MCO: 11029 Name: TARL Date: 3-Nov-83:15:55:28
[Symptom]
New: Move the ac set around. Re-organize their order to
approximate the tops-20 order, so that we can port tops20
monitor code more easily. In doing this, we formalize the
existance of seperate sets of AC names. These sets are:
TOPS10, DECNET, and TOPS20. Their orders are:
Number TOPS10 TOPS20 DECnet
0 S F FREE0
1 P P P
2 T1 T1 T1
3 T2 T2 T2
4 T3 T3 T3
5 T4 T4 T4
6 W Q1 T5
7 M Q2 T6
10 U Q3 FREE1
11 P1 P1 P1
12 P2 P2 P2
13 P3 P3 FREE2
14 P4 P4 MS
15 J P5 MB
16 F P6(.FP) (.FP)
17 R CX CX
The "TOPS20" acs aren't truly congruent to the TOPS20 set, since TOPS20 has
P being AC 17. Unfortunatley, there is too much fragile code which depends on
P being AC 1 in tops10.
The method of invoking these sets of ACs is via macro. Searching S will by
default invoke the TOPS10 set, changing to one of the other sets is done
by calling the T20SYM or D36SYM macro. Switching back to tops10 is done via
the T10SYM macro.
Beware: Any RTTRP or SNUP programs will have to be rewritten. Failing to do
so will cause you monitor to live short amounts of time.

MCO: 11042 Name: SMW Date: 16-Nov-83:16:08:53
[Symptom]
RP20'S can have 16 drives per kontroller, but we've
only supported 8.
[Diagnosis]
The way we used to build a monitor for 16 drives was to
build two KDB's (with 8 drives each). Besides being a
kludge, this results in a serious degradation in
performance.
1). RP20's can't do a position command on one drive when
there is a transfer in progress on another drive. If you're
smart, you start all the position commands before starting a
transfer. We run into trouble if we start a transfer on RNA
and then try to start a position on RNB (despite the fact
that there are two KDB's, these are both really the same
kontroller). It's impossible to start the position on RNB
at this time. RNXKON lies to FILIO and tells him that the
position command is already done. Later, an implied seek
will be done. An implied seek ties up the channel for
inordinate lengths of time. On a heavily loaded system it
was found that 1/3 of all transfers did implied seeks.
2). Swapping and queued protocol isn't as fast as it might
be. We try to decide which CPU to do the request on based
on which kontroller is idle. The fact that there are two
KDB's for the same kontroller makes it very hard to
accurately determine if the kontroller is really busy. The
existing code doesn't even try to get this case right.
[Cure]
Make RP20's have all 16 drives on a single KDB.

[Symptom]
Stopcode KCP if MCO 11042 is installed, needless
implied seeks if MCO 11042 is not installed.
[Diagnosis]
When a drive finishes a command, it normally takes the
next request from the queue. Due to the status of cache,
however, certain requests can only be done on a certain CPU
(despite the fact that both CPU's are ported to the drive).
We queue a clock request to come back on the other CPU and
start the command over there. By the time the clock ticks,
it is not necessarily true that the kontroller will still be
idle. We cannot start a position command on an RP20 if the
kontroller is busy.
[Cure]
When the clock ticks, check if the kontroller is busy.
If so, set the unit to position wait and dismiss the clock
request without starting anything. Later, when the current
transfer completes, FILIO will automatically take the next
request from the queue.

[Symptom]
LOGNUM off the number of login failures.
[Diagnosis]
ACCLG. UUO behaves as if the logging-in job is running on the CTY, OPR,
or a subjob of an operator job. Processing login failures for operator
jobs just happens to work by accident. User login failures cause LOGNUM
to be decremented twice, once in ACCLOG and once in CLRLOG. This is due
the fact that LOGIN uses the ACCLG. UUO incorrectly. LOGIN doesn't get
the LOGNUM interlock for operator jobs, which is OK, but it always tries
to clear the interlock. For user jobs, ACCLOG doesn't set the LOGNUM
interlock bit appropriately, causing CLRLOG to decrement LOGNUM one too
many times.
[Cure]
Crock up ACCLOG some more. This isn't a particularly good thing to do,
but at this late a stage in field test, it's the safest way to fix the
problem. The real solution is to re-think the LOGNUM/BATNUM problem
again, throw out the ACCLG. UUO, and start over with some cooperation
from LOGIN. Next release.

[Symptom]
Cache bug: Files written with big buffers are
corrupted. Problem is most likely to occur on a file which
is highly fragmented.
[Diagnosis]
We take the number of buffers which have been swept and
multiply by the number of blocks per buffer. This
theoretically gives us the number of blocks which have been
swept (i.e. the number of blocks we will transfer). This
value is too high, however, if some portion of the first
buffer has already been transferred. FILIO therefore thinks
that it's ok to transfer some portion of another buffer (one
that hasn't been swept yet).
[Cure]
Don't count the blocks that have already been
transferred.

[Symptom]
The RENAME UUO allows the user to change .RBVER, .RBSPL,
and .RBNCA of his UFD, but only if he changes the protection as well.
He can always do a second RENAME to change the protection back.
But why should he be required to do so?
[Diagnosis]
Ordinarily, the only operation an unprived job can do to
a UFD is to read it as a file. There is, however, an exception: the
owner is allowed to change the protection. The RENAME UUO then assumes
that if it's ok to change the protection, it must be ok to change
any of the other attributes as well. It is not legal, however, to
change any of the attributes unless the protection is changed as well.
[Cure]
Lie to CHKPRV, tell him we're changing the protection
when actually we're changing the attributes. Only lie if the
extension is UFD.

[Diagnosis]
That MCO stashes the SPT at die time, so that in looking at crashes
we have to look for the SPT in a different place than we would look
in a running monitor.

Since the problem is that REBOOT clobbers .CPSPT by calling SYSTR0,
have SYSTR0+ save the current value of the SPT, and REBOOT will restore
it. This also avoids some of the sticky issues which would arise if we
ever get a real full sized SPT.

Kind of a crock having a 1 word SPT.
[Diagnosis]
[Cure]
Make JBTUPM be a real SPT (only for the low segment for the time
being). The SPT slot's which map funny space are JBTUPM-CPU#. Thus the
SPT actually starts at JBTUPM-CPUN, and .CPSPT points at the slot to
be used by that CPU to map funny space. A context switch now becomes
MOVEM @.CPSPT
DATAO PAG,xxx
rather than
MOVEM .CPSPT
DATAO PAG,xxx
and all CPUs have the SPT base register pointing at the same address.
Namely, JBTUPM-CPUN.

[Symptom]
Hard to write a routine which does command parsing and wants to do
several PUSHs and then encounters an error.
[Diagnosis]
When an error occurs, tradition has it that one JRSTs to COMERA,
or if one level down, one JRSTs to COMERP which POPs one item off the stack.
If parsing is complicated, several items may have been PUSHed on the stack
and thus a JRST to either routine doesn't wind up back at COMRET but in the
boonies.
[Cure]
Make COMERP, COMERA, and friends exit via ABORTC which will ajust the
stack such that teh return is always to COMRET. This allows any command
processing routine to JRST to any of the error routines without worrying
about the stack.

[Symptom]
Problems with RP20's: 1). A servo problem on one
drive can cause other drives to drop off line, 2). Running
diagnostics on one drive (from the maintenance panel) can
cause trouble for the other drives (KCP stopcode, drive off
line, spurious I/O error).
[Diagnosis]
The device driver can't issue a new command if the
kontroller is still busy from the previous command (i.e.
the GO bit is still up). The above two conditions can cause
the kontroller to remain busy for longer than anticipated.
The monitor times out and decides to issue the next command.
This hangs the entire subsystem.
[Cure]
Exit from the device driver without issuing the new
command. Wait for the previous command to signal an
interrupt, then tell FILIO that both commands are done (this
is a lie). If the new command is a transfer, then lie to
FILIO and tell him "position done". FILIO will think he's
recovering from a hung transfer and will re-issue the
transfer command. If the new command is a position, then
tell filio "recal done". FILIO will think he's recovering
from a hung position and will re-issue the position command.

[Symptom]
LUUO's don't work in extended sections.
[Diagnosis]
Section 0 luuo's use locations 40 and 41, which are insufficient
for extended section luuos. The block used for trapping extended
LUUOs is a four word block pointed to by location 420 in the UPT.
[Cure]
Allow setting the pointer to this block with trap number
zero of the UTRP. uuo. The pointer is a full 30 bit address
to the four word block in user memory. The block looks like:
Block+0: Flags,,opcode of LUUO
Block+1: PC of LUUO
Block+2: Effective address of LUUO
Block+3: New PC.
You'll notice this looks oddly like the MUUO block at upt+424. It should.

[Symptom]
Not enough dispatch bits in command tables.
[Diagnosis]
Yes
[Cure]
Rearrange the command tables, assigning a table completely to the
bits, and another table exclusively for the dispatch address. UNQTAB is now
a table of one word entries with the post dispatch bits in the left
half and the predispatch and uniqueness bits in the right half. The
uniqueness bits must be the least significant bits so that we can
remain compatible with the user defined command tables which are still
compressed. DISP now contains the full word dispatch address. Dispatch
bit NOLOGC has been removed, since there was no longer a need for it.
The only logical name restictions now are the "R" and null commands.

[Symptom]
New: Move the default PFH into the monitor.
This eliminates only the functionality of fetching a default PFH when
no PFH is present; All page faults in these conditions are now handled
by the monitor. The old functionality of setting up a private PFH
continues to work.
This new PFH allows us to fix a number of outstanding virtual bugs, such as
dump mode filop I/O not working, that we never had room to fix. The new code
is considerably smaller than the old code, mainly by virtue of not having to
worry about overlaying and running in user mode. The algorithms are currently
much simpler than the old PFH (instead of a FIFO we have random page out),
and there is room for considerable experimentation.

manner: if the number of output buffers to be created is non-zero, and A
is non-zero, create the output buffer ring with buffers of size A+2.
Likewise, if the number of input buffers to be created is non-zero, and B
is non-zero, create the input buffer ring with buffers of size B+2. If the

[Symptom]
Virtual timer traps get cleared while PFH is still
around and active.
[Diagnosis]
Big fortran program gets pulled in by GET.EXE, which invokes
PFH.EXE before the program even gets started. PFH starts up,
and sets his virtual timer traps, and returns to the starting
program. This program, like all good programs, does a reset UUO
and ends up clearing the virtual timer traps. This does PFH
no good, since he never gets around to being called for garbage
collection.
[Cure]
Move the SETZM .USTMI from RESET into RMVPFH. The original
intent of MCO was simply to reset the timer between core images,
so that running OPR didn't cause the next program you ran
to go virtual. Zeroing the timer in RMVPFH makes more sense.

DN8x terminals can hang (stop output)
[Diagnosis]
If the -11 is EXTREMELY heavily loaded (loop service has not run for
20 clock ticks) then the DH/DZ output interrupt service starts shutting
down terminals in an attempt to "back off" and let loop service get
some cpu time (for routing, etc.), assuming that IRMA will eventually
get the line(s) restarted. Unfortunately, the line can be left without
DS.ACT (line active) set, in which case IRMA ignores that line.
[Cure]
Set DS.ACT for any line being "idled" due to overload.

SETUUO argument restrictions for setting minutes
till KSYS prohibits new OPR command, SET KSYS NOW <I mean it!>,
from working.
[Diagnosis]
SETUUO function for setting KSYS only allows
half-word argument value. To stop timesharing immediately, a
full-word -1 needs to be placed in SYSKTM.
[Cure]
If the argument to the SETUUO set KSYS function is 777777
(an immediate -1), change it to 777777,,777777 and then stuff it
in SYSKTM.

[Symptom]
Sporadic "?Illegal address in UUO" messages when creating an EXE file via
LINK on SMP systems.
[Diagnosis]
The CLOSE UUO calls RELSEG to see if we just superseded a known segment.
We wander into FNDSGU, where we set up a path pointer in .JDAT+SGAPPN.
Then, we call FNDSEG, which calls SRCSEG, which gets MM. When MM is not
available, we do a context switch, thus clobbering the dump ac we so
cleverly put our path pointer in.
[Cure]
PUSH/POP SGAPPN around the call to UPMM in SRCSEG.

[Symptom]
Cannot simulate SPY uuo with .PAGSP PAGE.
[Diagnosis]
People want to use the negative argument facility, so
they say "map 100 pages from monitor page 0 into user page 400".
When NXTPAG looks at .USNXP, he decides whether or not to
increment both halves by seeing if the left half is already
non-zero.
[Cure]
Make SPYPGS call NXTSPG, a routine which is similar to NXTPAG
but knows to increment both halves. This is a reasonable way to
fix this, since this is the only case where doing something to
page zero with a page uuo is legal.

[Symptom]
If all CPUs get a KAF stopcode at about the same time, they will
all loop, and the system must be reloaded by hand.
[Diagnosis]
The non-policy CPUs just went on ahead and jumped into their ACs, but
they never told the policy CPU that they died. Thus, the policy CPU
is waiting for a role switch to occur, so that it can die as a slave
CPU as well.
[Cure]
Have the slave CPUs tell the policy CPU that
they died, and have the loop for the policy CPU in
CPUSTP in ERRCON check occasionally to see if it is now the last
CPU and should do the reload. Have MONBTS check this
condition , so that we don't get two dumps for the same crash on
the same CPU.

Do not allow addresses in the range of 1 to 17 . Note that since
an address of 0 turns off address break but leaves the condition set,

Terminals with TERMINAL STOP and a non-zero PAGE lenght will go
into pause as though the monitor page limit had run out, even though
it has gone into terminal input wait less than the page limit
number of lines ago.
[Diagnosis]
The monitor will only clear the page count if there is no output to be done
before it goes into input wait. Often, it will go into input wait in
the code, while there are still characters to be output to the terminal.
[Cure]
At TWAITL, have the terminal wait until all characters have been sent,
then let it go into input wait.

MCO: 11194 Name: TARL Date: 7-May-84:04:01:35
[Symptom]
New: Six character STOPCD names.
This makes four major changes:
1) The code generated by the stopcd macro is now
XCT [
name:: PUSHJ P,DIE
SIXBIT /name/
XWD bits,cont addr
EXP typeout address
]
2) DIE handles the above format. DIE also now has an entry point PERISH
which handles the above format with a XPCW .CPSPC instead of PUSHJ DIE.
This could be used in cases where the stack pointer is suspect. (The
cases which come to mind are IME and KAF)
3) %SYSPC (prev. name,,pc) now contains a fullword PC. %SYSCD (new entry in
.GTSYS) contains the full stopcode name.
4) Location CRSWHY is now a fullword stopcode name, and the date/time/name
checksum has moved to the right half of CRSCHK in location 26.
Comment: With (2), it is possible to get into DIE without having pushed
the return address on the stack. To keep most of the code common (and to
fix some races), DIE now pops the STOPCD address off the stack early
in the game, so you can no longer say P/<Tab><backspace> to find the
stopcode. Currently, the way to find the stopcode is %SYSPC/<tab><backspace>.
a) Is it acceptable to have P look the way it is BEFORE calling the stopcode,
b) If (a), is %SYSPC a good enough location to look at? (if not, what?)

[Symptom]
1. I'm tired of use count crashes being mis-diagnosed.
2. A frequent failure mode (which used to be an IME in 7.02) is
now a KAF in 7.03. I liked it better back when it was a job
stopcode instead of a CPU stopcode.
[Diagnosis]
Attempt to CLOSE a file when the access table is
already on the free list.
[Cure]
Create a new stopcode: ALW (Access table Linked Wrong).
Make it a JOB stopcode.

[Symptom]
ORION can't find out where a 'SEND OPR' command came from
when the sender wasn't logged in.
[Diagnosis]
By the time the IPCF packet gets to ORION the sender's
job is gone or has been given to someone else.
[Cure]
Add a new QUEUE. UUO arg block, .QBTTY, and include it in the
IPCF message the monitor sends to ORION for a 'SEND OPR' command.
Put the SIXBIT TTY name of the sender in the block. This new arg
block should be reserved for the monitor's use only -- ORION
will only accept it if it comes from SYSTEM[GOPHER].

[Symptom]
WEM stopcodes are too generic.
[Diagnosis]
Person who wrote a lot of anf code was too lazy to think up
a lot of 3 character stopcode names, so he didn't bother.
[Cure]
Replace a large number of PUSHJ P,NTDSTP's with STOPCD's. The
generic rule was:
NETSER stopcodes became ANFxxx (where xxx relates to the comment)
NETMCR stopcodes became MCRxxx
NETTSK stopcodes became TSKxxx
NETDDP stopcodes became DDPxxx
The WEM stopcode still exists, and will continue to exist as a filler
location for dispatch tables and the like.
Also, while we're at it, change some other stopcode names. The specific
other cases are 6xx becomes DN60xx, 5xx becomes DC75xx, and 4xx becomes
RS04xx.

KAF while formating a disk with DDRPI.
[Diagnosis]
Super I/O causes the disk cache to be swept. The
number of blocks to sweep is computed by dividing DEVDMP by
200. This is not correct as the block size isn't
necessarily 200 words (headers and trailers are included
during formatting).
[Cure]
Don't sweep cache if the pack isn't mounted as a
structure. Don't sweep for negative block numbers.

[Symptom]
If you have EDDT loaded, and you happen to be so unfortunate
as to get your symbol table blown away, and then take a stopcd,
your monitor bites it off.
[Diagnosis]
DIE goes into DDT at the end of a STOPCD, and the only
way back out is via GOBACK$G, which won't work if you don't
have symbols.
[Cure]
Make DIE enter DDT via breakpoint with an XCT .CPDDT instead
of XCT SYSDDT. This means you can now say $P to continue your
monitor in the above tragedy.

Hung system.
[Diagnosis]
Someone had the absolutley terrible luck of getting
a PDL overflow in SVPPC, which caused a PIP stopcode,
which tried to enter secondary protocol by calling SVPPC.
Unfortunatley, SVPPC notices primary protocol isn't running,
and does nothing. THe original SVPPC never quite got around
to starting secondary protocol after breaking primary.
[Cure]
In SVPPC, if we decide we aren't in primary protocol,
enter secondary protocol anyway, just for paranoia's sake.

[Diagnosis]
Known bug.
[Cure]
Add a new resource CX. This will be used to insure that
VIRTAL won't go negative when more than one job attempts
to do some flavor of a save context. Since there is no
room left in the wait state field in JBTSTS, delete a bunch
of DECtape codes (D4, D5, D6, D7, and D8).

[Symptom]
1. After MCO 11204, 'SEND OPR' from a TTY/PTY controlled by
another TTY results in no text being passed to ORION.
2. MCO 11204 not complete. Node and line number of sender not
passed to ORION.
[Diagnosis]
1. LDB of the sender is not always the LDB of the controlling
terminal. Call to SENDHO returned U pointing to LDB of controlling
terminal. We need U pointing to the LDB of the sender when trying to get
characters he typed.
2. Yes.
[Cure]
1. Preserve U across call to SENDHO and GTNTSO.
2.Add code to pass node and line number of sender to ORION.

New: (Begin to) implement the "Don't care" bit for the
PAGE.UUO.
[Diagnosis]
This bit,if set,will cause the following effects:
1. For create/destroy,will cause NOOPs on pages that already
exist (create) or don't exist (destroy).
2. For page in/out,will cause NOOPs for those pages already
in (page in) or out (page out).
3. Exchange becomes a move in the appropriate direction if one
of the pages doesn't exist and a NOOP if both don't.
4. Move destroys the target page if it exists and is a NOOP if
the source page doesn't.
5. SPY page create/destroy will act akin to create/destroy.
6. REMAP will destroy target pages if they are in the way.
7. Create/destroy sections will act like create/destroy pages.
[Cure]
New bit is PG.IDC (100000 in the left half).

[Symptom]
ENQ. deadlock detection is broken.
[Diagnosis]
It was purposely broken by MCO 11226. Deadlock detection
involves tracing down queue chains for different contexts, but
QUESER doesn't know that jobs can have more than one context.
[Cure]
Teach QUESER about JCHs. The two job bit maps used by QUESER
are now replaced by two linked lists of JCHs. Restrict users from
ENQing any locks on files opened on channels 775, 776, or 777.
[This should not be a very important restriction, I assume.]
This MCO also adds a new routine CTXWAK to CTXSER. It claims to
wake up any context for any job, but really only wakes up a current
context for a job, and is a no-op for a not current context.
While we are at it, make all ENQ stop codes six characters long.
For the record, they are: ENQLNF, ENQDNL, ENQAVE, ENQCWD, ENQCWJ,
ENQIJC, ENQATA, and ENQQFU.
An interesting side-effect of this MCO is that job-wide locks are
actually useful for sharing resources between contexts of a job.

[Symptom]
1) CPU and device status blocks don't get read and/or reported on a
parity error on a single CPU system.
2) CPU and device status blocks get read and reported on all CPUs
except the one that had a parity error on an SMP system
3) CPUSTS clobbers SBUS errors when called.
[Diagnosis]
1) No code to do it.
2) All other CPUs call CHKDIE which calls RCDSTB in case we are DIEing.
3) Call is to REDSBC instead of REDSBD.
[Cure]
1) Add code.
2) Leave this the way it is since it might be useful but document it.
3) Call REDSBD.

[Symptom]
Use of a one word global byte pointer where the P&S
field is 77 causes a "KA10 floating point instruction" error
message.
[Diagnosis]
The code to handle illegal instructions is lazy in
testing for KA10 floating point instructions. It believes all
instructions between UFA (130) and FDVRB (177) are KA10 floating
point instructions. The byte instructions fall right in the
middle of that range.
[Cure]
Test for the byte instructions before the KA10 floating
point instructions. If the instruction is a byte instruction,
just give an "Illegal instruction" error message.

[Symptom]
1. IME while doing an ENQC. status function.
2. Occasionally an unowned long-term lock will never, ever go away.
3. Some locks don't get their date-time stamp fixed up on a SET DATE
or SET DAYTIME command.
4. It is possible for a job to log off with a permanent lock still
active, contrary to documentation.
5. The number of queued requests for a lock (returned by the ENQC.
status function) is always zero.
[Diagnosis]
1. The ENQC. status function didn't allow for the possibility that
a long-term lock might not have any owners or queued requests at
all. The code simply treated the lock block as a queue block entry,
and things went downhill from there.
2. Off-by-one bug in ENQMIN (once-a-minute code).
3. Off-by-one bug in ENQSDT (set date-time code).
4. Off-by-one bug in ENQNDR ("no delete on reset" code).
5. After carefully storing the count of queued requests in the left
half of P2, QUESER does a LOAD of a half word quantity into P2.
The LOAD assembles to an HLRZ, which will zero the left half of P2.
[Cure]
1. If there are no owners or queued requests, return -1 in the
right half of the first status word, and zero for everything else.
2. SOJG ==> SOJGE
3. SOJG ==> SOJGE
4. SOJG ==> SOJGE
5. This last bug is very interesting. I suspect no one has ever
used this field. However, instead of fixing it to correspond to the
documentation, change the documentation and then change the code to
reflect the new documentation. The documentation will now state
that the ENQC. status function returns the number of sharers of
the resource in the left half of the third status word.

[Symptom]
SETUUO functions to set the date (.STDAT), the current
time (.STDAY, .STTMS), and to set the KSYS timer (.STKSY) can
fail to perform their function on an SMP system.
[Diagnosis]
The code which sets up the new date and time isn't
interlocked from the updating of those values by CLOCK1. The
code which sets the KSYS timer isn't interlocked from the code
which tests and decrements it in CLOCK1. When setting a new
date or time, we aren't clearing the remainder from the last
universal data time computation.
[Cure]
Have these SETUUO functions run only on the policy CPU
so they are interlocked from CLOCK1's updating. When setting
a new date or time, clear the remainder left from the last
calculation.

MAPSLT still isn't right. Since MAPSLT must now scan the

from a core address.

Invent bit PM.COR as part of the map entry. This bit is turned on
when a disk address is translated to a core address and off when the

[Symptom]
Not enough free wait state codes.
[Diagnosis]
DECtapes still use up too many wait state codes, particularly
for an "unsupported" device.
[Cure]
Multiplex the DECtape wait state codes through an interlock word
in the master DECtape DDB. The word formerly was the routine to call
to wait (DnWAIT), so we don't need any more words in the DDB. The word
now contains the job number of the owning job.
Also add JBT table JBTDTC (see also MCO 11298) which contains
which master DECtape DDB the job is waiting for so the schedular can
unwind the resource properly.
The new wait state code is DT.

[Symptom]
Too many free wait state codes.
[Diagnosis]
MCO 11297, as you remember, freed up some wait state codes.
Since entropy must always increase on a universal scale, it's now time
to make the IPCF interlock into a real wait state code (incidentally, the
^C code for the IPCF interlock was broken recently anyway).
[Cure]
The new wait state code is IP.
This code uses the other (right) half of JBTDTC (called JBTIPC here)
which contains the JCH of the job we wish to interlock, so that the
schedular can unwind the resource properly.

[Symptom]
New: Implement multi-section FILOP. dump mode I/O. See extended
addressing spec for details.
[Diagnosis]
[Cure]
Well,let me put a little of it here, just for the fun of it.
This new form dump mode I/O uses an IOWD list composed of word pairs
instead of IOWDS. The word pairs are
1) Positive count of words to read/write
2) Address of first word touched by IO
If word (1) is zero, the pair is a goto, and word (2) is the 30 bit
address to go to. If a goto is to 0, that terminates the iowd list.
This is implemented by calling the PFH IOWD breakdown code from DMPIO,
and he will call filser (or whomever) with old-fashioned IOWDS of
128k or less. The reason for 128K limit is that under 7.03 positive IOWDS
don't work (cause unknown) - The limit is easy to change.

scheme will therefore allow the addition of other devices as time goes

[Symptom]
Spurious IO.IMP error while doing output to spooled
device.
[Diagnosis]
The first output to a spooled device forces an ENTER
UUO. The monitor makes up a filename that it hopes will be
unique. If it is not unique (i.e. the ENTER returns error
code 4) then the monitor tries for a new filename.
Unfortunately, the error code is only 18 bits wide and the
code does a 36 bit compare.
[Cure]
Do 18 bit compare. Check for both error codes 3 and 4
(file being modified, and file already exists,
respectively).

DZ based dataset lines behave VERY slowly on a KS10.
It may take tens of seconds for the autobaud character to be recognized.
[Diagnosis]
DZ dataset timing is based on being called once/tic. If M.STOF
is non-zero, it won't be. So with M.STOF=7 (a typical value for the KS),
it takes 16 seconds for carrier stabilization to time out. (Instead of 2)
[Cure]
Teach DZQADD to allow for M.STOF. Make STOPAT global - this makes
it easier for those folks who like to patch this on the fly as well.

[Symptom]
Now that we're going to support the CI disks, there's too
much free disk space per square inch of machine room.
[Diagnosis]
Since, as we learned back in MCO 11298, entropy must always
increase on a universal scale, it's time to use up the disk space.
[Cure]
Teach the swapper to use 21-bit (including unit #) disk addresses.
This divides into 3 bits of unit # and 18 bits of unit-relative address.
Changes of interest to others:
1. PM.ZER is now 21 bits wide, no longer less than a half word.
2. The address portion of page map entries, PM.ADR, is now no longer
less than a half word.
3. Symbol PM.NAD refers to all bits of a page map entry not part of the
address field.
4. Internal format of an IPCF packet header has been changed; the user's
format remains unchanged. The new internal format uses word .IPCFI
instead of .IPCFP (although when mapping from the internal to the
external format, it is the same word relative to the beginning of the
packet header). The "disk address" bit, formerly bit 18, is now
bit zero. The length, formerly the high order 18 bits is now 10
bits starting at bit 1. The address portion is the low order 21 bits.
Byte pointers PKLNxx where "xx" is the AC name to index off of (base
address of the packet header) will load the length. Length of 1000
is now used internally for page mode packets (along with the IP.CFV bit)
instead of -1.
5. JBT table rearrangement: NZSICN and NZSSCN (# of non-zero section
maps desired and have, respectively) are now six bit fields in the left
half of JBTIMI. JBTSWP is now 36 bits wide, right justified, except
that the fragmentation bit is still the sign bit.

File is left in FILE BEING MODIFIED state when a get
of PFH fails and the file is open on channel zero.
[Diagnosis]
GETXXX pushes USRJDA+0 and then uses channel zero for it's
own purposes. Unfortunatley, there are many ways that GETXXX can
bomb out that do not return via POPJ, so we never restore USRJDA+0.
Even RESET and CORE 0 never fix this, because there are no pointers
to the DDB, and thus to the access tables.
[Cure]
Don't just push and pop USRJDA+0. Allocate an extended channel,
copy USRJDA+0 to this place, and then move it back when we are done.
This way, when MERGE blows up, the pointer to the DDB is left in
a channel that IOALL can blow away.
Note that in 7.03 this is less critical, since we no longer read
in a PFH.EXE - The only thing we use GETXXX for is getting VMDDT.

[SYSTEM]INFO is the wrong place for the quota and its enforcement.
[Cure]
Move it into IPCSER. The CREATE function to [SYSTEM]IPCC is now unprivileged,
and will check against the invoker's PID quota, unless a privileged message was
sent. Not checking on a privileged send makes this case compatible with the
old scheme of PID creation.
This also adds the [SYSTEM]IPCC functions .IPCQS and .IPCQR to set and read
the PID quota.

[Symptom]
Virtual memory performance isn't as good as it could be.
[Diagnosis]
Too much paging I/O and when paging I/O is done ,its not as
efficient as it could be.
[Cure]
Implement an in-core cache of "paged out" pages including IPCF pages.
There are 4 new linked lists in PAGTAB. Two are lists of pages which have
been "paged out" via the PAGE. UUO, but have yet to be written to the
swapping space (one keeps track of IPCF pages and pages to go to the slow
swapping space, the other keeps track of normal paged out pages). The third
list is to keep track of pages which are being written to the disk and pages
migrate from the first two lists to this list when core is needed. Swapping
space is allocated contigously so the swap out is fast and before the
swapout begins, disk addresses are moved to the maps of all jobs which
have "paged out" pages. When the I/O completes, the pages are moved to the
fourth list. If core is needed, allocation can be done from the fourth list,
but only if there are no pages on the free core list.
When a "page in" is requested via a PAGE. UUO, if the page in question is
on the first two or the fourth list, it is simply given back to the job
giving back swapping space if necessary. If the page is on the I/O in progress
list, the job must block until the I/O completes.

PTYs go into TO wait state at end of page (sometimes.)
[Diagnosis]
MCO 11161 didn't take PTYs into account when it checked
to see if the page counter should be cleared.
[Cure]
If no characters have to be output, clear the line counter
always. If there are characters to be output, check to see if the
terminal is a PTY and if it is, always clear the page counter.

When a file is RENAMEd or updated, it is impossible to
change the existing account string for the file, even from a
privileged program. This is contrary to documentation.
[Diagnosis]
No code to do so.

Add code to enable a privileged user to specify a new
account string on an extended RENAME or update operation on
a file. If no account string is specified, the existing one
will be unchanged.

not have IPCF privileges enabled, this bit will be
ignored.
1B1 IP.CMI Indirect sender's PID. Word 2 (.IPCMI) contains the address
(30-bit or IFIW) of the PID to use, rather than the PID itself.
See .IPCMI for more information.

(0) Default INFO process
.IPCCC [SYSTEM]IPCC
.IPCCF [SYSTEM]INFO
.IPCCP [local]INFO
Any other value in this field will result in the IPCUF% error.
len field:
777777 IP.CML Total length of argument block, including this word.
May be 2 or 3. Any other value in this field will result
in the IPCUF% error.
word 1 .IPCMP Pointer to message block (detailed below). This pointer
can be either a 30-bit address or an IFIW. If it is an IFIW,
it is evaluated in the same section as that of the argument
block itself (i.e., the same section as that from which it
was fetched). No indexing or indirection allowed.
word 2 .IPCMI In-your-behalf word. PID on whose behalf to perform this
operation, or 0 to do it for the user's own job. If this
value is specified, then either the PID given must belong
to the user's current JCH, or the user must have IPCF
privileges enabled. If the PID belongs to someone else,
and the user does not have IPCF privileges enabled, the
IPCPI% error will result.
The message block for [SYSTEM]IPCC:
word 0 .IPCS0 xwd length,function
where length includes this word, and function is
the [SYSTEM]IPCC function desired to have performed.
word 1 .IPCS1 As documented for [SYSTEM]IPCC data packets.

Any data that the system process would return in a packet for the same function
will be returned in the user's message block.
Any of the errors that can be returned from the process, either on the send
or in the returned packet, can be returned by this UUO (with the exception of
those relating to page mode). Any error code returned by this UUO will be
returned in the user's AC.

[Symptom]
"?Job capacity exceeded" message appears when there are still
plenty of job slots left.
[Diagnosis]
This message is printed for three different reasons:
1) The maximum job capacity has really been exceeded.
2) There are no free TTY DDBs to allocate to a new job.
3) There is not enough free core to allocate a PDB for a new job.
Case 2) can occur rapidly if there are a lot of slave TTYs on
the system.
[Cure]
Append more informative error messages in cases 2 and 3
"?Job capacity exceeded (No free TTY DDBs)"
"?Job capacity exceeded (No core for a PDB)"
A naive user can either ignore extra info or tell his system programmer
what the specific error message is.
Redefine parameter TTXTRA to include the number of slave lines which
the monitor dedicates to DTEs on a KL10. This will increase the
number of TTY DDBs available.

[Symptom]
1) Cannot clear the aborted status of a lock by using the ENQ. modify function.
2) Cannot change the status of a lock from shared to exclusive by using the ENQ.
modify function, even when the user is the only sharer of a lock.
3) [1,2] jobs requesting shared global locks instead get exclusive global locks.
[Diagnosis]
1) The documentation clearly states that the aborted status of a lock
can be cleared by issuing an ENQ. modify function with EQ.FAB clear,
but the code also clearly never implemented this case.
2) For the second case, the documentation states this is possible, and
there is much code to support it. However, this code must never have
been tested, because it cannot possibly work as coded.
3) The third case is reasonably obscure. It requires having a [1,2] job that
doesn't have the JP.ENQ privilege. The subroutine that causes the problem
is documented as saving all the ACs, but it calls PRVBIT which normally
will preserve all ACs, except in this very case.
[Cure]
1) Add code to handle clearing the abort status with an ENQ. modify function.
2) Add missing instruction to skip over the lock block in a queue block chain.
3) Call SAVT to preserve all the temp ACs, before calling PRVBIT.

In the sequence OPEN-LOOKUP-USETI, the USETI takes the
block number as being relative to the file. In the sequence
OPEN-USETI, however, the block number is taken as being
relative to the structure (super I/O). The question is,
what should the sequence OPEN-ENTER-USETI do? (presently it
does super I/O).
[Diagnosis]
This is not the expected sequence. The user probably
made a mistake, and it would be dangerous to let him
continue.
[Cure]
Make the sequence OPEN-ENTER-USETI be illegal. It will
return an IO.IMP error. Likewise, OPEN-LOOKUP-USETO will be
illegal.

CORE UUO doesn't work in non-zero sections.
[Diagnosis]
VIRCHK doesn't know about sections.
[Cure]
Make VIRCHK use the PAGE UUO code for all CORE UUOs. Note that a CORE UUO behaves slightly
different in a non-zero section, since .UPREL, .UPMEM, etc. do not exist.
In particular, all a CORE UUO really guarantees in a non-zero section is
that all pages up to the given address exist. Pages which existed below
the given address are unaffected, as are pages above the given address.
In order for this code to work, new functionality has been added
to the .PAGCH (used to be "create high-seg", now "change high-seg") (aka
.PAGRM) function. If only one arg is now given (which used to be
illegal), then that arg is the number of pages to delete off of the
end of the high seg. If a negative number of pages is given, then the
specified number of pages is remapped from the low seg location into
the high seg.

[Symptom]
Various problems with eternal and aborted locks:
1) Eternal locks held by a context go into limbo when the context is
POPped. They can never be dequeued by any process, ever.
The same problem could potentially happen with a LOGOUT UUO.
2) Eternal locks cannot be made uneternal by an ENQ. modify function.
3) Locks do not become eternal or aborted if the resource requested
is owned by another context and the request must be queued.
4) A shared lock that is modified by one owner to become eternal
makes the lock eternal for all other sharers even though the
sharers never originally requested an eternal lock.
5) If contexts are queued for a resource, and the current owner
of the lock aborts the resource, the contexts queued for the
resource never get informed that the resource was aborted.
[Diagnosis]
Eternal and aborted locks were never completely thought out.
[Cure]
1) We could disallow popping a context that holds eternal locks,
but this adds unnecessary clutter to CTXSER. Instead, give
the eternal locks to whichever context we are popping to. This
still satisfies the requirement that eternal locks never go away.
If we ever get as far as a LOGOUT UUO, just delete the locks.
2) Change the ENQ. modify function so that a request with EQ.FEL
clear will now make a lock not eternal.
3) Move the eternal and abort flags from the lock block to the queue
block. This will insure that the flags are associated with the
current owner of the resource.
4) Only consider the lock to be eternal for the context that
requested it that way.
5) When a resource is aborted, wake up all waiters for the resource.
The waiters then check to see if they were woken up because the
resource they were waiting for was aborted. If so, return ENQAB%.
In the case that the waiters were expecting a PSI interrupt, give
them the interrupt, but set the sign bit in the status word to
indicate that at least one of the context requests was aborted.

of DIE, which will put stuff in normal SCNSER tty chunks for
OPR0. The format this stuff will type out on the CTY is:
%% BUGINF xxxxxx FOO: 0,0 BAR: 1,1
where FOO and BAR are the additional data fields (if any). This
still calls DAEMON for a stopcode, and (since DAEMON uses them)
still stores the ACs in .CPCAC.

[Symptom]
ONCCOM mechanism to request I/O on non-boot CPUs during once-only
doesn't work.
[Diagnosis]
For reasons unknown, the AC loop used by CPUs to wait for the boot
CPU to start was changed to use the once-only AC loop. Non-boot
CPUs spin their wheels waiting to autoconfigure. By the time ONCMOD
runs, it expects AUTCON to have finished. When ONCMOD AOS'ed the
non-boot's OK word, it ran AUTCON instead. Hence, a bunch of new
UDBs were built, but their structures were never mounted.
[Cure]
Change to use the correct AC loop.

Yes.
[Cure]
Fix it. Introduce error codes for the PIINI. UUO:
PIIBC%, Illegal bit or section number given
PIADC%, Address check
PINFS%, No monitor free space.
These error codes, plus the ability to give 30-bit vector addresses or
IFIW pointers, should be good enough for most people. See the section on
the software interrupt system in the user-mode extended addressing spec.

[Symptom]
1) If a remote node crashes (or the path to the remote node is
othewise lost) whilst a CONNECT to that node is pending then the
program or job that issued the CONNECT (e.g., OPEN monitor call or
ASSIGN monitor command) is stuck in network Event Wait.
2) Programs using PSI trapping are not informed when network
devices (especially TSK devices) go "offline" due to the remote node's
having crashed (or otherwise become inaccessible).
[Diagnosis]
1) The code to handle "Node Down" in NETSER was overly paranoid
about not NETWAKing a job when it shouldn't. In particular, for the
case of a CONNECT awaiting confirmation, the DDB will NOT have either
ASSCON or ASSPRG set for the device. These flags won't get set until
NETSER has successfully connected the device and returned it to UUOCON
for active use.
2) This is essentially the same as "1" above, aggravated by the
general lack of consistency of handling of this case by the various
device-type-specific service routines in NETDEV.
[Cure]
Both problems are fixed via a general cleanup of the "Network
Disconnect" and "Node Down" processing.
This fix implements a new extended I/O status code IONDD% which is
returned when a network device initiates a disconnect (rather than the
owning job). This error code distinguishes a "Node Down" condition
(extended error code IONND%) from a disconnecting device (currently
only TSK can initiate a disconnect).

Return: ac/ Bit mask (1B35=CPU0, etc.)
.RCIOW Wait for active I/O to finish on the system

Both of the returns mentioned above are the skip returns. Normal failure
returns also exist, with the usual RECON. error codes possible.

[Symptom]
CTX. UUO address checking doesn't work right.
[Diagnosis]
Should call TRNGE, but that halts the job if a bad address is
given. The CTX. UUO has an address check error code and I'd
like to use it.
[Cure]
Add a new UUO level address checking routine called ARNGE. It
takes two arguments: T1 has a user specified address and T2
a length. The address can be a full 30-bits or an IFIW word.
ARNGE has three returns:
1. CPOPJ if any address in the range is illegal
(i.e. non-existant, bad section number, etc.).
2. CPOPJ1 if the address is OK but illegal for I/O.
3. CPOPJ2 if the address is OK.
Addresses are allowed to cross section boundries only if a global
address was given. Attempts to span more than one section with
an IFIW will give the address check return.
The range of addresses is considered illegal for I/O if any page
is not marked as writeable in a page map. Also, if any section is
mapped to section zero and the target address is less then JOBPFI,
the range of addresses will be considered illegal for I/O.
ARNGE preserves PCS and all ACs. It resides in DATMAN. Eventually,
all calls to LRNGE and TRNGE should be replaced by calls to ARNGE so
that UUOs which are capable of returning address check error codes
may do so instead of halting the job as is currently done. ARNGE
supersedes routines RRNGE and WRNGE used only by QUESER.

global byte pointers, plus they call LRNGE and TRNGE which will

[Diagnosis]
OWGBPs are new stuff and TRNGE was all we had.
[Cure]
Remove QRNGE altogether. Teach PRNGE about OWGBPs and have it call
ARNGE. While we're at it, VMSER is too big and DATMAN isn't big
enough, so move PRNGE into DPRNGE into DATMAN.

[Symptom]
Stopcode SRO.
[Diagnosis]
There really is a lot of swap space available, but it is all
tied up in dormant high segs. The actual amount of
swap space immediately available is very small. The swap space
allocator calls IFDELE, finding it could make enough space available
by deleting dormant segments, causing it to call DODELE. DODELE's
function is to make available the desired amount of swap space by
deleting dormant high segs.
Unfortunately DODELE only guarantees that the prerequisite
amount of space is available, and makes no claims as to the
fragmentation pattern of said swap space. It can happen that
the order in which the space appears is such that the UPT and
MAP pages would be split across a fragment boundary. This
is not allowed, hence we go to look for more space elsewhere
(at this point it must be immediately available, not tied up
in dormant segments) and find none, hence the SRO.
An equivalent, although much more unlikely scenario is
that the swap space is so badly fragmented that the UPT and MAP
pages would be split across a fragment boundary no matter what
order the swap space were allocated in.
[Cure]
Remove the restriction on having the UPT and MAP pages
in the same fragment.The disk address of the MAP page is stored
in JBTAD2 (reference by byte pointer JBYMAP)on swap out; the address of the UPT is in JBTSWP as usual.

[Symptom]
MAPBAK doesn't.
[Diagnosis]
Code at THIS tries to keep the map pointer slot for
.UPMAP from being clobbered on a swapout, but it doesn't work
if the MAP page is the first page after crossing a cylinder
boundary.
[Cure]
Change MAPBAK to use the SECTAB pointer for section 0 to
reset the .UPMAP pointer; the SECTAB pointer is never translated.

Typing DDT after an address break occurs executes instructions
after the break instruction until a UUO is executed.
[Diagnosis]
Confusion about whether the PC is in user mode when the DDT
command is executed after the address break occurs. Specifically,it
isn't since it is somewhere in the middle of SEILM.
[Cure]
Clean up the stack and call the scheduler with the user mode
continue PC in .CPPC.

New: 7.03 sources for DN8x.
There is no new functionality in this MCO, just a slight
rearrangement and cleanup of some code.
The DNCDDH and DNDM11 modules are now defunct, and are
superseded by (included within) the DNDH11 module, anyone using
DH11-based datasets or DDCMP links should change their control
files accordingly (i.e., remove the DNDM11 and DNCDDH modules).
The DNCDDH and DNDM11 modules are still physically extant, and
if assembled will PRINTX that they shouldn't be assembled any-
more (but will not error/abort the batch job).

[Symptom]
QUEUE. UUO argument fetching doesn't work correctly in a non-zero
section using indexing and indirection. Likewise, G-floating point
instruction simulation doesn't work either.
[Diagnosis]
Routine CHKIND doesn't know about NZS and global indirect pointers.
[Cure]
Let the hardware resolve addresses. Add a new routine called EACALC.
It takes a user virtual address of a word containing possible
indirection and indexing. PCS must be set up. IFIWs are respected.
A non-skip return indicates the EA calculation referenced an illegal
address. Skip return have the respolved address in T1. No legality
checks are made on the address. GETWRD or PUTWRD will handle that.

[Symptom]
Random IPCF screwups using contexts.
[Diagnosis]
No way to interlock a context's data base. The CX
resource exists but it's system wide. It's also not
being used right now.
[Cure]
Change the CX resource to be job specific. This adds
word .PDCTO to the PDB. It contains the JCH of the job
whose interlock is desired in the LH and the JCH of the
job who owns this job's interlock. The new CX resource
management behaves like the AU, DA, and IP resources.
That is, code exists to unwind the scheduler, etc.

[Symptom]
No way to find out the contexts owned by a job.
[Diagnosis]
The spec implied there would be some way, but at the time it
was written, we didn't know what we wanted.
[Cure]
Add function .CTDIR which will return a directory of all contexts
for the specified job in the data buffer. The first word contains
the job number or -1 for the current job. The second word is filled
in with the number of words required or returned with directory
information by the monitor. The third word is the start of the
actual data containing byte-streams of context numbers. Each stream
represents one context chain and is terminated with a null (since
context #0 is illegal, this is OK). The byte pointer to the byte
stream can be GETTAB'ed (%CTBDM).

The DN8x TROLL is an unwieldy glutton.
[Diagnosis]
The troll gets hungry based on the bit pattern of the -11's uptime,
so it tends to be hungry about half of the time, thereby feasting
on about half of the hapless NCL messages passing through that -11,
thus starving anyone downwind of him.
[Cure]
Base the troll's appetite on the amount of traffic rather than on a
percentage of elapsed time (i.e., eat every n'th message).

[Symptom]
CTX. UUO not as useful as it could be.
[Diagnosis]
Often, a program will create an inferior context and run a program
at the CCL entry point. Usually, a TMPCOR file will be written.
Writing TMPCOR prior to issuing the CTX. UUO isn't impossible to do,
but it involves saving any existing file, writing a new one, doing
the CTX. UUO and finally putting the old TMPCOR file back again. It
would be desirable if the CTX. UUO would write the TMPCOR file in the
new context's funny space, thus eliminating the need for the user
program to save and restore the state of TMPCOR himself.
[Cure]
Add a new bit (CT.TCR) to the CTX. UUO flag word which indicates the
first two words of the data buffer contain the standard TMPCOR UUO two
word pointer to a user buffer to be copied into the inferior context's
funny space.

[Symptom]
KS Networks Don't.
In Particular:
1. Mongen defined line uses get ignored; people run crocks like ANF and
DECnet.EXE.
2. DDCMP doesn't meet corporate spec. Confuses others, and ourself.
3. %Unexpected restart on ... messages unexpectedly restart, producing
a black, illegible mess.
4. Adjacent node congestion.
5. Adjacent node remote reply timeouts.
6. Sundries.
[Diagnosis]
We're VERY confused.
1. BLTing zero over line user in KDL
2. Was coded to match ANF, almost. DECnet expects otherwise.
3. When we get a START on a running line, we don't halt DDCMP, we just
try and restart it.
4. Data messages aren't ACK'd until the other end sends a REP5. We idle REPs on DECnet lines.
6. Of course.
[Cure]
Of course.
1.Don't
2.Change to conform to spec
3.Halt DDCMP before restarting. Eg, send a STRT, not a STACK.
4.Always ACK data messages immediately. Note that this may not be
a seperate message; it can be piggybacked if the phase of the moon is OK.
5.Don't. ANF will continue to idle REPs, as this is how it determines line
down. This change causes the line timer to have a "stopped" state, per
the spec.
6.yes.

Output to a -20F LP20 printer succeeds even though the
VFU is bad and -20F had previously told us of this.
[Diagnosis]
If an idle -20F LP20 printer is powered off and then on,
-20F informs us that the printer is back online (after telling us it went
offline, of course) and that the VFU is not loaded. DLPSER carefully
sets the extended error code and lites the IO.ERR bits in S, but if
IOACT is not lit in S, these bits are never put in DEVIOS(F). Subsequent
OUTs to the printer succeed which can cause LPTSPL's headers and trailer
pages to look quite strange.
[Cure]
Make sure the error status in S gets stored in DEVIOS(F) regardless
of whether or not IOACT is lit in S. At DLPTK3+0, insert a MOVEM S,DEVIOS(S).

TMR and other STOPCDs when OPR defines a large disk and
believes the MAX value for # SATs/unit. Observed on RP07.
[Diagnosis]
ASKSPU tries to figure out how many retrieval pointers
(= SAT clusters) will fit in the RIB it builds. It cleverly allows
for all the change of unit pointers, and the prime RIB.
It fails to allow for the redundant RIB and the possible EOF pointer.
The TMR happens when we try to add the spare RIB pointer.
Because TMR is a HALT STOPCD, 20F tries to help things go further
downhill.

[Symptom]
The KL10 can fail in such a way that the DN8X doesn't detect it, thus
essentially hanging the -11 since the -11 will wait indefinitely for
the -10 to respond. Note that most normal failues will result in clearing
the DTE, thus informing the -11 that the -10 has died.
[Diagnosis]
The -11 only looks for "E-bus parity error" to decide if the -10 has
kroaked off, leaving open such things as the -10 has simply HALTed.
[Cure]
Nominally the current operation is the desired operation. However, for
those "high-availability" sites that might want the -11 to immediately
reroute terminal/et al connections if the KL stops running in any
fashion, add a new feature test FTKLKR to the DN8X code which, if
enabled (non-zero) will abort DTE protocol if the KL goes into the
HALT loop, gets a Clock Error Stop, or clears the RUN flop (something
only 20F is alleged capable of doing).

[Symptom]
DN8X terminals (and RDAs) can hang, especially on a heavily-loaded
-11.
[Diagnosis]
Improper error checking in the DH11 interrupt service routine, leading
the -11 to ignore NXM errors (the -11 tested for NXM by seeing if the
DH11 had transmit done set, and if so, assuming all was ok with the
DH11).
[Cure]
Check for NXM error explicitly, and take the appropriate error recovery
action.
Note that this problem doesn't arise with DZ11 lines, as the DZ11
doesn't care about such minutiae as NXM errors.

[Symptom]
NEW: Change the behaviour of deadlock detection when a time limit is
specified on the ENQ. request. Currently, deadlock detection is performed
when a request cannot be granted. If the request will not cause a deadlock,
the job HIBERs until the request is granted or the time limit expires.
The behaviour will now be: if a request cannot be granted, HIBER the job
first, until the request is granted or the time limit expires. If the time
limit expires, then do deadlock detection to see if that is the real cause.
However, the default case of a time limit of 0 (meaning HIBER forever),
will always check for deadlock before HIBERing the job.
This change has the effect of reducing the overhead cost of deadlock
detection. In most cases, if a request is not available, it will shortly
be freed by the owner. Deadlock is a very rare case, and will only be
checked for if a reasonable amount of time has passed.
Another bonus is that a form of deadlock priority can be implemented.
Batch jobs could specify a long wait time, while interactive jobs could
specify a short wait time. The interactive job, which wants quick response,
will time out first, and back out of the transaction because of deadlock.
The batch job, which probably has more time invested in its transaction,
can afford to wait longer, and therefore gets to continue processing.

[Diagnosis]
We could be kinder.
[Cure]
Add MONGEN symbol M.PCST (Number of PDB words reserved for customer use.
If defined, and non-zero, will allocate that number of words at symbol .PDCST.
The value of .PDCST is not fixed; it should be the last entry in the PDB.
If zero, .PDCST will not be defined. Customers can equate their words to
.PDCST+nnn.

No free core. TGHA conquers system.
[Diagnosis]
MOSSER is very happy to send ever MOS error that occurs to TGHA
for analysis. Each is an IPCF packet. When 17,000 (decimal) errors happen
in one metered minute, free core goes away. If things are this bad, TGHA
isn't doing much good anyhow.
[Cure]
Limit the maximum number of MOS errors /minute to some rational number.
Currently that's 5, but it can be patched at MOSMEM in MOSSER.
Add the following items to the PARITY subtable:
.CPMET - MOS errors this minute
.CPMEC - MOS errors that we tried to send to TGHA
.CPTME - Total MOS errors - filtered or not.

TU78 tape drives hang during rewind.
[Diagnosis]
MCO 11483 removed a seemingly useless instruction which prevented
T78KON from updating the density in the IORB twice. Doing this
saved about 10 instructions. Now rewinds hang until the rewind
hung timer expire.
[Cure]
If setting the density once is good, then doing it twice must be
better. It's cheaper to waste a few instructions than to spend a
couple of hours trying to understand this one.

[Symptom]
New: Add support for new bootstrap. This MCO eliminates the monitor
resident bootstrap (MONBTS) and the need to assemble microcodes into
the monitor. The BOOT loaded by RSX-20F or the KS10 will be mapped
into the monitor's virtual address space, thus allowing the monitor to
call it as a subroutine or to access data such as the microcodes with
little effort. From now on, the monitor will be dependent on BOOT
version 3(22) or later to provide the following functions:
1. Dump crashes.
2. System sleep dump.
3. Memory parity error page replacement.
4. Microcode storage for:
A. DX20/TX02 tape controllers.
B. DX20/RP20 disk controllers.
C. KLIPA/CI20 controllers.
5. The storage of vital information across monitor crashes,
necessary for auto-reload with no operator in attendance:
A. System search list.
B. Active swapping list.
C. System dump list.
The new BOOT is completely self contained, and has no knowledge of
monitor addresses. All commumications between the monitor and BOOT
are done through an entry vector which contains actual data or pointers
to data inside BOOT.
BOOT resides in section 6. Originally, it was to be put in section 7
with the NZS high seg code, but section 7 address space usage depends
on assembled-in addresses in the source code. Since BOOT is relocatable,
it made more sense to put it in another section. If desired, it could
be moved into sections 2 or 3 with no effort.
For the time being, MONBTS will exist as a collection of subroutines
used to interface to the new BOOT. This may change in the near future.
Support for the old BOOTS and the monitor resident bootstrap is no
longer an option, as the code has been completely removed. This
caused COMMON.MAC to shrink by about 15 blocks.

[Symptom]
Hard to upgrade an SMP system with MCA25s. Must buy as many MCAs as you have
CPUs. Also, since all of the new CPUs we make have MCA25s, all existing CPUs
would have to be upgraded to add a new CPU. This could all be quite expensive
and doesn't allow as graceful incremental growth.
[Diagnosis]
[Cure]
Turn on the "keep me" bit in all maps, but if a particular CPU
doesn't have an MCA25, don't turn it on in the section pointers. Since the
access bits get anded together, the "keep me" bit won't get propagated to
the pager thus causing page table parity errors. Thus CPUs with the MCA25
can take advantage of "keep me" without causing CPUs without it to get page
table parity errors.

[Symptom]
DZ11 terminal speeds can be left in the wrong state (i.e., the true
terminal speed is not what the user specified).
[Diagnosis]
A program must issue two TRMOP.s in order to set both transmit and
receive speeds for the DZ11. If the program is (e.g.,) scheduled or
otherwise interrupted between the two TRMOP.s, the -11 will be
notified of the partial speed change, and will reject it since it
appears to be an attempt to set the DZ to split-speed, which the DZ11
does not support. The -11 will then send back to the -10 the
"correct" (i.e., unaltered) speed. The user program then continues,
setting the other speed, which again sends a partial (or split) speed
request to the -11, which is also rejected. The end result is that
both TRMOP.s appear to succeed (take the skip return) but in fact the
-11 did not change the terminal's speed.
[Cure]
For DZ11 lines, rather than ignoring/rejecting split-speed requests,
just ignore the terminal receive speed and believe only the terminal
transmit speed.

...+1/ udx
...+2/ len,,addr2
addr2+/ mask ! values ! character
The field TC.MOD is a bit-mask of the values to change, TC.VAL is the new
values, and TC.CHR is the character to which they apply.
Bits which can appear in TC.VAL or TC.MOD:
TC.BRK ;This is a line break character
TC.NSA ;No special action (disable normal monitor action)
TC.OOB ;Out-of-band (receipt of this character causes
; an interrupt)
TC.DFR ;This character's interrupt type is deferred
TC.CLR ;The input buffer is cleared when posting the
; interrupt for this character (meaningful only
; for control characters)

DN8X assembly options confusing, hard to document, etc.
[Diagnosis]
My guess is that it just grew up that-a-way.
[Cure]
Change the async line configuration instructions as follows:
DH11-based systems use the DHCNFG and DHUSE macros as currently documented
with the exception that the arguments to the DHUSE macro are ***NOT*** to
be enclosed in parenthesis as shown in the examples.
DZ11-based systems no longer use the DHCNFG and DHUSE macros but instead
use the DZCNFG and DZUSE macros, which are invoked exactly as the DHCNFG
and DHUSE macros are.
DN20 systems now assume DZ11s and TTY support as the default case (this is
easy to change back, but I think the majority of DN20s are configured
with TTYs).
While it was reccommended that the TTYN parameter be supplied explicitly
in the DN8X control file, that parameter is no correctly defined by the
DHUSE/DZUSE macros.
*ALL* arguments to the DHUSE/DZUSE macros must be supplied correctly
(and in particular - for emphasis - NO PARENTHESIS!!!).
To suppress TTYs set FTDH11=0 or FTDZ11=0 depending on the class of -11
(DN8? or DN2? respectively). To force TTY support, set the corresponding
symbol non-zero and invoke the appropriate D?CNFG and D?USE macros.
The DZSPD macro has been added to correspond to the DHSPD macro,but for
DZ11-based systems.
Two new assembly macros are added - DHSET and DZSET, to be invoked within
the DHCNFG or DZCNFG macros respectively. DHSET/DZSET must be invoked before
the DHUSE/DZUSE macros. Each takes four arguments, physical line number,
line class ("TTY", "RDA", etc.), receive speed and transmit speed. These
macros look like DHSPD but use the physical line rather than logical line
with specified class of lines, and set the class of the line.
The FT.RDE assembly parameter has been removed. Use only FT.RDM for
multi-point DDCMP RDX device support, or FT.RDP for point-to-point DDCMP
RDX device support. FT.RDA continues to be used for ASCII RDA.

Add yet more CTERM-related code. This time, it's the following commands:
TTY [NO] UNPAUSE [o]
TTY [NO] ESCAPE [o]
TTY [NO] EIGHTBIT
and the new I/O mode .IOAS8 (4) for 8-bit ASCII. This mode uses 8-bit bytes
and keeps an accurate byte count, in the same fashion as mode 2 (PIM).
The use of TTY UNPAUSE and TTY ESCAPE is either as
TTY NO word ;to go back to using only the normal character
or
TTY word octal ;to specify that the given octal character code

If TTY EIGHTBIT is enabled, the full 8-bit ASCII character set will be
transferred to and from the terminal. If disabled, the 7-bit character set
will be used.
The following (corresponding) TRMOP.s are also implemented:
.TOUNP ;read/set the extra unpause character
.TOESC ;read/set the extra escape character
.TO8BT ;read/set the 8-bit terminal characteristic.

[Symptom]
Customer commands not always accessible.
[Diagnosis]
The SPCCMD macro is expanded too far down in the tables.
If a DEC command is found that exactly matches the customer one,
it will be executed, and the customer one won't be looked at.
[Cure]
Move the SPCCMD macro up in the NAMES macro so that it expands
right after the HALT command. If the customer wants more flexibility
he can use the uniqueness bits.

New: Expand ANF LN01 support:
Add I/O status flag IO.SVF (bit 25) to suppress DN8x VFU/etc.
(as in LN01 graphics where font files or the like are being
loaded).
Add 8-bit ASCII support. Any attempt to use a non-703 ANF LPT
or a 703 LPT that doesn't support 8-bit ASCII will return IO.IMP
error status (but the OPEN will always work, you won't get the
error until actual I/O is attempted).
Add new DN8X assembly parameter LPn8BT to specify that the
designated LPT supports 8-bit mode. (Note that the actual
utilization of 8-bit is controlled by STATUS messages from the
-10, so that 703 8-bit DN8x LPTs will work correctly with
7.02 7-bit monitors! And vice-versa! Boy, what a pain!)
This is speced out in more detail in LN01NT.MEM.

Enable/disable the action of ^V (control-V) as a super-quote character.
When TTY QUOTE is enabled, the ^V-<any character> combination will behave in

INITIA and the monitor can't agree as to who is using FRCLIN.
[Diagnosis]
Interlock is only per character.
[Cure]
Change the interlock to be per call to FRCSET or to the .TOTYP TRMOP.
Now, once INITIA starts sending multiple (but related) lines, it and
the monitor will be protected from each other.
This MCO also adds a range check to the .TOTYP TRMOP., such that if the
user tries to send more than TTIMAX (300) characters, we will return
error code 2 (range error). It seems better to inform the user of the
impossibility of success than to claim to have done the impossible.

At startup, the monitor will first try to use the preserved data, and
if it can't, a message will be output saying the SSL, ASL, or SDL will
be rebuilt from this disk data base. This adds three new startup option
switches (/NOSSL, /NOASL, and /NOSDL) to override the preserved data and
do things the old way.

[Symptom]
People get confused as to what the 'TTY [NO] ECHO' command really does.
[Diagnosis]
It was misnamed.
[Cure]
Fix it by renaming the command to TTY [NO] LOCALCOPY. Then, because so many
people have requested it, add a TTY [NO] ECHO command that really controls
echoing. If TTY NO ECHO has been typed, the monitor will echo no characters,
no matter what the user's setting of IO.SUP. If TTY ECHO is in effect, echoing
will be controled by IO.SUP as before.
New read/set TRMOP.: .TOCLE (command-level echo enable)
GETLCH bits of interest:
GL.CNE,1B4 ;Command-level no echo (TTY NO ECHO in effect)
GL.8BM,1B10 ;Terminal is open in 8-bit I/O mode
GL.SLV,1B12 ;TTY SLAVE is in effect
Some of these bits are old but never-before documented. All three are read-only
(that is, they do not apply to SETLCH).

Auto-disconnect timing feature too confusing, and too hard to expand for new
network types.
[Diagnosis]
Implemented on an ad-hoc basis for each new network type.
[Cure]
Make SCNSER's once-a-second code handle the auto-disconnect timer.
This adds the read-set TRMOP. .TOMXT (maximum timeout value), and the read
function .TOADT (remaining time on auto-disconnect timer).
The following symbols can be set by MONGEN:
IDLSEC [90] ;countdown timer (in seconds) for idle lines
M.DIDL [IDLSEC] ;countdown timer for idle datasets
M.AIDL [IDLSEC] ;countdown timer for ANF-10 lines
M.LIDL [IDLSEC] ;countdown timer for LAT lines
M.NIDL [IDLSEC] ;countdown timer for NRT/CTERM lines
These are the default values, which can be overridden via the .TOMXT TRMOP.

[Symptom]
Can't specify how to map customer terminal types to 'standard' types for
exchanging CTERM messages.
[Diagnosis]
No code.
[Cure]
Add code.
Summary of changes:
1. MONGEN accepts terminal definitions of the form
TTY33/LT33,72,0,..... as well as the old
TTY33,72,0,...
2. The TERMCR macro in COMDEV takes an optional second arg, the
alias name for the first. The remaining args follow as usual.
3. TRMTAB/TRMNAM entries are generated only if the alias name is
specified and is different from the TOPS-10 name.
4. COMDEV is still SOUP compatibile with previous monitors. Old
MONGEN .CTL files need not be changed.
The resulting code is no prettier than previously, but no worse either.

NETSER wastes freecore.
NDBSNM (station name pointer) always points to a 4-word block, of which we
use at most one. NDBSID (software ID pointer) always points to an 8-word
block, which is sometimes not needed. In fact, it is usually not needed if
your network has a lot of DCPs. It also points to a date string block, which
is also often not needed.
[Diagnosis]
Inefficient use of space.
[Cure]
Change NDBSNM to point to a new word (NDBSN2) in the NDB, and not allocate
a separate 4-word block to hold the sixbit name. Only allocate blocks
for NDBSID to point to if strings are supplied by the node.

SVEUB gets called and in previous monitors, when a POPJ occured,
SVEUB would have done a DATAO PAG which would have cleared the paging memory.
However, in 7.02 to try to save the refills, SVEUB only does that DATAO if the
UBR is being changed. Thus, even though the map has been redone, no one told the
paging memory that the mapping had been changed.

[Symptom]
Too hard for programs to find out about what kinds of pages
they have.
New:
1. Add PAGE. UUO function .PAGBM. This function will return a bit map
where the bit being on represents a page which fulfils the specified
attributes. The calling sequence is:
MOVE AC,[.PAGBM,,addr]
PAGE. AC,
error return
normal return
addr: EXP count ;# of args
EXP attribute-settings ;same bits as .PAGCA
EXP care-mask
EXP starting-page-#
(start of bit mask returned)
The 'attribute-settings' word specifies the desired state of the
appropriate page accesibility attribute. The 'care-mask' word specifies
which bits of the 'attribute-settings' word should be examined.
The starting page number specifies which page maps to bit 0 of the
mask.
2. Add PAGE. UUO function .PAGAL. This function will return the same
information as .PAGCA, but will take a list formatted argument list.
The calling sequence is:
MOVE AC,[.PAGAL,,addr]
PAGE. AC,
error return
normal return
addr: count ;# of args
EXP starting-page
(start of returned area)
The bits returned are the same as for .PAGCA
3. Add new bits to values for the above two functions and .PAGCA:
PA.GNS ;Page is in a non-existent section
PA.GVR ;Page is a virtual spy page
Also, for .PAGCA and .PAGAL, return PA.GPN for spy pages, the virtual
or physical target page being SPYed upon.

All errors will update the argument block appropriately, just like a success
return. On a success return, the AC is unchanged. The byte pointers returned
will have any indirection and indexing resolved, and will be expanded from
one-word global format to two-word global format if a OWGBP was specified.

LOGIN can't always attach to the desired job.
[Diagnosis]
ATTACH UUO fails because LOGIN is running logged-in on a
local terminal trying to attach to a detached job. The
code to prevent the attach from suceeding is trying to
protect the stupid REATTA program (which is unsupported).

New: Add the TRMOP. function .TOUNR (unread) to allow reading only the
already echoed characters without worrying about allowing further echo.
This is needed for CTHNRT to be able to perform the CTERM UNREAD function.
CALL: MOVE AC,[2,,ADDR]

Once an unread is done, input will not block (or allow echoing) until
an empty buffer is returned (IN/INPUT UUOs) or a null character is returned
(INCHRW/INCHWL) or the 'no input available' return is taken (INCHSL/INCHRS).
After this termination condition is met, subsequent attempts to perfrom input
will behave normally.

[Symptom]
Refresher loses blocks.
[Diagnosis]
REFSTR was changed in 7.02 to allocate UFDs near the center
of the structure. It does by calling TAKBLK asking for -1 blocks
starting at block <unit size>/2. REFSTR knows this allocation
will fail, but will leave the correct SAT positioned for future
allocation of the UFDs. Unfortunately, TAKBL is reducing the
allocation from -1 to <group size> blocks, which causes the
allocation to succeed. Zap, some lost blocks.
[Cure]
Test for DINITF in TAKBL and don't reduce allocation if set.

written, but if a crash occurs before then too bad.

[Symptom]
Output data can be lost on DN8x "RDM" (multipoint (DDCMP) RDX)
terminals.
[Diagnosis]
The DN8x tries to avoid "congestion" of DDCMP lines by throwing away
"unimportant" DDCMP messages such as REPs, NAKs, etc. if the DDCMP
output queue for a DDCMP line starts getting backed up (which is to
say has more than 40 messages queued). Unfortunately, output destined
for a multipoint DDCMP line slips through the check for "real data"
and can be thrown away. Since the "real data" has already been NCL
ACKed it is irretrievably lost.
[Cure]
If the DDCMP line is a multipoint line then assume that the line is an
RDM terminal line and preserve the data (i.e., assume that the data is
NOT NCL network data and therefore not recoverable).

[Symptom]
Not enough room in high core to autoconfigure a large system with a monitor
containing service routines for all devices and all software options.
[Diagnosis]
Only 256K of virtual address space in section 0.
[Cure]
Invent a new mechanism which allows intrasection calls between section 0, 1
and higher sections. This mechanism is in the form
SNCALL (subr,sn)
where subr is the name of the subroutine to be called, and sn is the section
the subroutine is to be executed in. The code generated has the effect of
doing a PUSHJ P,subr in section number sn. Return is nonskip/skip to the
caller in the section that the call was executed in.
At system startup, move any code located between MONTOP (alias VMEND), and
MONEND to section MS.HGH (currently section 7).
Using the above, put DECnet in section 7 by inserting SNCALLs as appropriate
and loading D36COM, DNADLL, LLINKS, NTMAN, ROUTER, SCLINK, and SCMUUO between
MONTOP and MONEND. Section 0, 1, and 7 are mapped 1:1 but the DECnet code is
only mapped in section 7. This allows the DECnet modules to address anything
between 0 and VMEND, but DECnet itself can only be called via SNCALL and
section changing calls executed within DECnet must use SNCALL.
The above gives us about 35 pages of high section 0/1 core which can be used
for autoconfiguring and 10-12 pages of symbol table back since the high and
high high (DECnet) segments can be moved to the top of section 0 (reserving
space for autoconfiguration is no longer necessary).
The above means that the load order of monitor modules is important. Anything
loaded between VMSER and the new monitor module MONEND will end up in section
MS.HGH and will not be addressable in section 0/1.

MCO: 11819 Name: RDH Date: 11-Feb-85:00:53:00
[Symptom]
Problems with multipoint RDX output:
1. User program gets undeserved IO.IMP error return from OUT of
large (but not erroneously so) buffers to multipoint RDX
devices;
2. Data requests can be lost;
3. Output data is "hung" in the -10 and never gets sent;
4. Blocking output doesn't block (i.e., can take a non-blocking
return to the user program from the OUT monitor call);
5. Possible WEM stopcode;
(Note: this MCO supersedes MCO 11801)
[Diagnosis]
If the buffer is too large to fit the 'default' 32-word PCB size
allocated by the monitor, the user's buffer is split across multiple
PCBs for transmission to the remote. Unfortunately RDXSER needs to
put the multipoint 'DROP' number into each message, so it treats the
first part of each PCB's worth of data as the five-digit drop number,
usually finding 'junk' on all but the first segment of the buffer
(where the drop number is supposed to be), so lighting IO.IMP and
aborting the OUT monitor call.
Further, if RDXSER cannot get a PCB to send the buffer, it doesn't
correctly "back out" of the transmit attempt. The data request count
has already been decremented, and is not re-incremented. The drop
number has already been parsed, and is lost. Also, the "error" (i.e.,
"non-blocking") return to UUOCON is always taken, whether or not the
RDM device is OPENed in a non-blocking I/O mode.
Finally, the "drop" number field is not counted in the NCL "COUNT"
field.
[Cure]
Dynamically calculate the PCB buffer size based on the size of the
output request from the user. If the user's buffer contains more data
than either the RDX device's maximum message size (RDEMML parameter in
the DN8x) or the network maximum message size (MSGMAX parameter in the
7.02 monitor) then abort the output and return an IO.BKT error to the
user. Note that this means that the segmenting of user data buffers
over the ANF network is NOT supported for multipoint RDX devices.
When RDXSER is unable to get a PCB, back up the DEVAXO byte pointer
and counter to the begining of the drop number so that the next time
through ROLOOP (the RDX output service loop) it can again reparse the
drop number. Take the non-blocking return to UUOCON iff the RDM
device is OPENed in a non-blocking I/O mode, otherwise call NETSLP
(i.e., block) waiting for a free PCB to do the output. (Note that in
this hopefully-rare case of non-blocking I/O being unable to do the
output because of the lack of a PCB, the user program cannot depend on
getting an (e.g.,) "output-done" PSI interrupt. Instead the user
program must have some sort of "hung timer" which will cause the OUT
monitor call to be re-executed at some time in the future if all the
output buffers have not been sent. This is not a new condition,
merely a non-obvious one of which the programmer should be cognizant.)
The data request count is automatically kept accurate in 7.02 by not
decrementing the count until the PCB has been sent (This involved
splitting 7.01's NTDCDQ routine into two routines - NTDCDQ to check if
any data requests are available, and NTDDDQ to actually decrement the
data request count after the PCB has been queued for output).
Finally, include the drop number in the NCL message "COUNT" field when
building the NCL data message.

[Symptom]
DTE ANF10 nodes can TRAP unnecessarily on a power fail restart.
[Diagnosis]
On a power fail restart TENSCB may be non-zero on entry
to routine DTEINI but the SCB it points to will be zeroed by
routine CLRSCB. When the DTE's are checked at loop level, INTLPS
will be called because TENSCB is non-zero and a TRAP will occur
because .PRDTE (primary DTE) is zero.
[Cure]
Always if .PRDTE is cleared, TENSCB should be cleared since

[Symptom]
Despite the contrary documentation, you can not supply an
expression to Decimal symbol, value.
If you supply an expression in Octal symbol, value, it may not contain
the * or ! operators, nor nested <>.
Config text may not contain *.
[Diagnosis]
MCO 10954 was a good idea, but it didn't go far enough.
[Cure]
Allow any legal expression in either octal or decimal symbol
definitions. (SIXBIT expressions are pointless). Allow * in config.

SCHED. function 32 (set free core goals/limits) requires that the
user provide the number of pages that must be free and potentially free to
cause the swapper to swap out jobs in long term wait. The typical system
adminstrator wouldn't even have any idea how many pages of user core he has
available.
[Diagnosis]
[Cure]
Change the arguments to percentages of free and potentialy free core.

[Symptom]
Random stopcodes caused by running a job which is in ^C state.
Usual symptom is an EUE.
[Diagnosis]
The wondrous swapper of 7.02 is multithreaded. Unfortunately
the background batch variables and their relationship to the rest of
the swapper isn't. If a background batch job is being fitted in at
the same time a normal job is, and FININ runs across the normal job
first, it will mark the normal job as on the just-in list (for background
batch, that is) and mark it as background batch, even if it isn't. We
eventually pick the job to run because it's on the just-in list even though
it's in STOPQ or CMQ which don't have runnable jobs in them.
We can also try to fit more than one background batch
into core at once and we'll only remember the last.
[Cure]
1. SKIPN-->CAME; SETZM-->CAMN,SETZM.
2. SKIPN (don't try and fit more than one background batch job in at a time).

[Symptom]
If a RTTRP interrupt which does a WAKE UUO occurs between the
time a HIBER UUO puts the SLPQ code into JBTSTS and the time SETSLP/SETNAP
put the SLPQ/NAPQ code into JBTSTS (for a HIBER with a non-zero sleep time)
(at SETSTT), then the job stays asleep instead of running immediately on
as should have been the case.
[Diagnosis]
HIBER sets up to sleep, then releases SYSPIF after setting
the SLPQ code. Unfortunately, if there's a non-zero sleep time,
the MSLEEP is called to set up the clock queue entry and again
jams SLPQ/NAPQ into JBTSTS. If the WAKE occured between the first
and second settings of JBTSTS, the WAKE gets lost.
[Cure]
Rearrange HIBER to set the queue only once.

[Symptom]
Output data can be lost on DN8x "Decnet Compatible Port" lines.
[Diagnosis]
The DN8x tries to avoid "congestion" of DDCMP lines by throwing away
"unimportant" DDCMP messages such as REPs, NAKs, etc. if the DDCMP
output queue for a DDCMP line starts getting backed up (which is to
say has more than 40 messages queued). Unfortunately, output destined
for a DECnet compatible port DDCMP line slips through the check for
"real data" and can be thrown away. Since the "real data" has already
been NCL ACKed it is irretrievably lost.
[Cure]
If the DDCMP line is a DECnet compatible port line then preserve the
data (i.e., assume that the data is NOT NCL network data and therefore
not recoverable).

Stopcode IME yanking structure
[Diagnosis]
UNISAB isn't zeroed after removing a structure. If we
wind up at WTUSAT (possible in CLOSE/RELEASE code) we will
attempt to link down SABRNG. SABRNG for the first SAB will
probably have been clobbered by GVFWDS and things go down
hill when we step to the next SAB.
[Cure]
Have TSTGIV zero UNISAB when it returns SAB core. TSTGIV already
does this for SPT core. Change TSTGIV to zero UNISAB and UNISPT
BEFORE returning the core so WTUSAT doesn't think a SAB is still
set up while we're blocked in GVFWDS returning the space. Also
check in WTUSAT after calling SATWRT to see if UNISAB got zeroed
while we were blocked in UUOPWQ, and exit from WTUSAT if so.

[Symptom]
1. WEM stopcodes
2. QUASAR has a hard time mounting (REASSIgning) ANF devices to users who
request them.
3. Even if (2) above worked, QUASAR still couldn't set the logical
name of an ANF device for a user before REASSIgnment.
[Diagnosis]
1. DEVOP. code to clear DVCMDA in DDB mistakingly clears
the label status bits in DEVIOS of non-magtape DDBs. When this
happens to network DDBs, NETSER gets upset when attempting to
disconnect the device.
2. After each UUO, network devices (DDBs) that are not assigned are
disconnected via ZAPNET. QUASAR has to do 2 UUOs before the REASSIgn
UUO (DEVOP to set DVCMDA, and DEVLNM to set logical name), however
after each UUO, the network device is disconnected. This makes it almost
impossible for QUASAR to "mount" ANF devices for users.
3. DEVLNM makes sure the owner of a device is the one trying to set the
logical name, or if it isn't owned, MDA is the one.
The check for MDA is only done if the job number in DEVJOB is zero.
If the DDB was created by MAKDDB when MDA was doing the DEVOP. to lite
DVCMDA, MDA's job number will be in DEVJOB.
[Cure]
1. In DVPMDC, JUMPN T3,CPOPJ1 => JUMPGE T3,CPOPJ1.
2. Don't call ZAPNET to disconnect a network device if DVCMDA is lit in
DEVCHR(F).
3. If the device isn't assigned and if MDA is doing the DEVLNM and MDA's job
number is also in DEVJOB(F), let the DEVLNM succeed.

New:
GETTAB table .GTVIR = job's virtual size. Index by job number (not a
segment-table).
GETTAB .GTCNF entry %CNIVM = 'AND' mask for .GTIMI/.GTIMO/.GTVIR.
Documentation: GTIMI is the job's physical memory size while in actual
physical memory. GTVIR is the job's total virtual memory size. Both
GETTABs include 'extraneous' stuff in high order bits, and should be
ANDed with %CNIVM to generate an actual page count (at this writing,
%CNIVM = 7,,777777 = 21-bit's worth of page count[*]). Other quirks:
GTIMI includes non-shareable high segment size (but *NOT* shareable
high segments); GTVIR does *NOT* include non-shareable high segment
size (which is - at this writing - found in bits 6-14 of GTVIR[*]);
GTIMI is a job+segment table (shareable high segment physical size
found by segment number); GTVIR is job-only table; Neither table
contain monitor-overhead page count (which are more-subtly scattered
around - at this writing, the page-map and other "per-process" page
count is bits 12-17 of GTPDB[*], while the non-zero-section-map page
count is bits 9-14 of GTIMI[*]; together these two quantities consitute
the "monitor overhead" page count for the job).
[*] = Precise details subject to vacillation at random developers'
whims, so probably a bad documentation risk . . .

Dangling bits in LDBREM
[Cure]
Make the "NETWORK" LDBs into a true "free pool" of LDBs under the
control of SCNSER. This way NRTSER/LATSER/othercronies won't have
to steal ANF terminals, then try to give them back without ANF's
noticing.
GETLDB is routine in SCNSER to call with server-class flag in T1
(LTLANF, LTLNRT, LTLLAT). Return is skip with U/address of LDB if
successful, otherwise non-skip.
DETLDB is routine in SCNSER to call with LDB address in U. Return
is non-skip always with the LDB/DDB detached/etc. Generally, you
should call DETLDB immediately before FRELDB.
FRELDB is routine in SCNSER to call with LDB address in U. Return
is non-skip always. The referenced LDB is returned to SCNSER's
free pool of available LDBS.
The caller is responsible for "customizing" the LDB according to
his needs.
The LDBTTW word has new bits in it:
LTLANF ANF network virtual terminal
LTLNRT DECnot NRT/CTERM terminal
LTLLAT LAT terminal
LTLREM "OR" of all the above
LTLUSE LDB-in-use flag
In particular, note the disappearance of LDRREM from LDBDCH.
New stopcode: LDBNIU - "LDB Not In Use" - occurs whenever a call to
FRELDB is made (e.g., from NETMCR for ANF, NRTSER for DECnet NRT/CTERM,
LATSER for LAT terminals) for a terminal which does not have the LTLUSE
bit set in the LDBTTW word of the terminal's LDB (the LTLUSE bit should
have been set on the successful return from GETLDB).

[Symptom]
If a job is locking in core, and another job grabs a page
which was made free for the first job (the page is for a DDB, for
example), then the swapper hangs until the second job releases
the page.
[Diagnosis]
Pages get put on the free list as LOKCON makes them
available for a locking job, but they're free game there for
anyone who is in core and wants one.
[Cure]
Don't put pages on the free list when they're being made free
for a locked job. Put them on a new queue (linked via PAGTAB and
PT2TAB). This queue is moved to the free list just before the
job is moved into place. Since the pages aren't on the free queue
until the MM is held, and are allocated properly by the time
the MM is released, the above race can no longer happen.
This entails fixing bugs in the maintenance of PT2TAB for pages
on the free list. It also means making all core returning go
through GVPAGS, where pages will be put on LOKCON's queue
instead of the free queue when they are returned, if the bit
P2.LIP (Lock in Progress) is set in PT2TAB for the page (set
at the time the job begins to lock).

Programs doing output to an ASSIGNed RDX device can hang in network
event wait.
[Diagnosis]
The IOSREL "device-has-been-RELEASed" flag in the RDX device's DEVIOS
word is not being cleared. This will cause the RDX device service
routine to not be NETWAKed if the job ever blocks for output (waiting
for data requests).
Note that this can only happen to ASSIGNed RDX devices - if the RDX
device was not ASSIGNed then the entire DDB was destroyed when the
RELEAS was performed and the device disconnected.
[Cure]
Clear the IOSREL flag on the first call to the output service routine
(this is the convention for network devices).

On some systems, a magtape cannot be referenced using MTxu:.
[Diagnosis]
If a system has two or more tape controllers and at least two
of any one type of controller, the number of magtape entries
in GENTAB is insufficient for all DDBs generated by AUTCON.
[Cure]
Assume there will be at least two of every type controller per
CPU and build that many GENTAB entries. Since GENTAB is built
at assembly time and the actual number of tape controllers cannot
be determined until AUTCON runs, this solution may not be sufficent
to cover a worst case situation (i.e. three DX10s in a single CPU
system). However the likelyhood of this sort of configuration is
quite remote. In a normal configuration, there is little justification
for dynamically building GENTAB. We will address the worst case
situation when it arises.

[Symptom]
Stopcode BAC, IMEs, or EUEs. Messed up PDL also possible.
[Diagnosis]
A job is sending an IPCF packet to EXEC. Before it could increment
.EPIPC for EXEC, it gets interrupted and someone else sends something
to EXEC. Both packets get processed thus decrementing .EPIPC twice,
but we didn't count it up for the original job yet. The second
decrement could cause the count to go to -1, but since we're dealing
with a 9-bit field, the next field (count of outstanding sends) gets
wiped. Eventually we pick up a packet which doesn't exist and either
cause a BAC trying to give back core, or get an IME trying to reference
it, or if the address is zero, muck with the packet header thereby
smashing the ACs.
[Cure]
AOS .EPIPC when the target context is interlocked.

[Symptom]
Too hard to share a CI bus among several systems.
[Diagnosis]
The disks get in the way. If you have lots of extra money you
can buy lots of HSC-50's and spread the disks across them, and set
the software disable flag for certain nodes for specific HSC-50's.
This isn't terribly easy and is prone to errors which will take a
lot of hair pulling and blue air before they are discovered.
[Cure]
Implement the (tuh-duh) "Uncommon File System". This software
will provide a means to restrict certain disks to certain systems.
The code is contained in the "FTSETS" conditional, defined in F.MAC.
This conditional will be set FALSE in the distributed FGEN.HLP.
No support of this code is implied by its existance. The code
is only provided to assist customers who wish to try such bold
undertakings. More detailed documentation will be available on
the Customer-Supported tape.

Confusion in FILSER when calling CTGOOD. We report

LAT circuits die too quickly.
[Diagnosis]
When we get notified that the NI went down, we kill
all LAT circuits almost immediately.
[Cure]
Since the NI may reappear very quickly on the other CPU (if SMP)
or the same CPU (if KLNI being reloaded), just keep the circuits alive.
If the NI is really dead, the normal circuit time-out mechanism will
kill the circuits within a minute or two.

[Symptom]
New: Allow "local" terminals (e.g., RSX20F) to be ASSIGNed via
ANF network connects - i.e., allow a remote host to assign
local host terminals.
Salient arcana:
The connect will be rejected if SCHED 10 is set.
The connect will be rejected if the terminal is 'busy', where
busy means one or more of the following:
Has a command pending;
Has a DDB (in use either to control a job or for I/O);
Has been SET HOSTed already.
The connect will be rejected if the terminal is a PTY, the CTY,
or an ANF terminal (caveat: whilst this might be construed to
mean that a NRT/LAT terminal is eligible for assigning, this
turns out to not be the case, as the 'CONFIG' message sent out
by the -10 only says it has 'n' local terminals where 'n' is
less than the ANF/NRT/LAT pool of LDBs, so the remote will never
attempt to assign that-high-a-numbered terminal, comma, although
if any remote were to blindly ignore the configuration and
try to assign the terminal anyway [Shame! -ed], it would be allowed
to succeed modulo the above-named restrictions).

[Symptom]
Autobauded dial in lines on RSX20F front ends lie about their speed
just after autobaud detection is complete. This can confuse customer
modified versions of INITIA that complain if the line speed is set to
an illegal value.
[Diagnosis]
This happens because sometime before the autobaud detection is
complete, we're told that the line is set to 2400 baud (the autobaud
test speed). After speed detection has completed, it can be a long
time before the front end tells us what the line's speed really is.
In the mean time, all we've got to tell TRMOP. is the possibly bogus
value of 2400, with no discernable way of knowing that it's wrong.
[Cure]
Fixing RSX20F to send the speed right away is a fairly major undertaking,
and fixing TTDINT to always wait for the speed to arrive just puts
needless delays in the dial in process, as well as making dialups
potentially less reliable. It would seem that the best cure is
to continue telling lies about the line speed, but in the most
obvious fashion possible: Set the line's speed bytes in the LDB
to zero when we receive the dataset connect message from the front
end; they'll be updated with the correct line speed when we receive
the speed message. If a customer has modified his INITIA to watch
for certain line speeds, he can make INITIA wait for the speed to
be non-zero before the test.

[Symptom]
The usual collection of stopcodes caused by yanking a structure while
I/O is in progress.
[Diagnosis]
Too little attention paid to shutting units down gracefully. We barrel
ahead and start dissolving SDB to UDB links as soon as we bump UNIGEN.
No attempt is made to let I/O complete before ripping the structure
apart.
[Cure]
Set the "No New Accesses" flag in the UDB as the first thing done in the
STRUUO "remove structure" function. Next, bump UNIGEN for all units in
the structure. This will cause I/O which is started on these units
subsequent to this to fail. Now give up the CB resource to allow jobs
blocked in FILSER to try to finish what they are doing. Finally, wait
for any queued or active I/O on these units to complete before getting
the CB resource back. At this point we are relatively safe taking the
structure apart.

The customer defined commands are still being searched
along with the normal commands.
[Cure]
Define a new table of customer defined commands. These commands
are defined using the MONGEN dialogue, as usual, but they will be
placed in their own table, and searched right after the user DECLARed
commands. The heirarchy to search is as follows: First the user defined
commands are searched. If an exact match is not found, we search the
customer table. If a match is found, we do not search the regular table
but rather, we will take the customer entry. We will only search the
regular commands if all else fails.
New GETTAB .GTCCM = 204 to allow HELP to access the table.

[Diagnosis]
BBFLAG can get set by one CPU running a lost time
scan after the other CPU has cleared it just prior to doing a QSCAN
for the swapper. This is because the CPU which clears the flag doesn't
do it under the schedular interlock. Note that this can't happen
in 7.01 because the schedular holds onto SCDLOK over the call to the
swapper.

[Symptom]
Stopcode PIP last seen; IMEs and other random assorted stopcodes
possible.
[Diagnosis]
Other scenarios are possible but one example is:
1. Job A whose UPT is physical page X gets swapped out. Note that
the slot in the UPT which points to itself ("370") points to page
X since we don't wipe out this slot in the UPT so MAPBAK has
an easier time of things.
2. Job B, which starts out on the swap space, gets swapped in, and
it so happens that the page that is used for its UPT is X.
3. Job B does something like disk I/O.
4. Job A types a command. COMCON calls SVEUB to set up mapping for
for the job, even though job isn't swapped in. Assume the command
requires the job to be in core, so it is diddly-com'd and the
swapping I/O is set up to bring the job into core.
5. One of the times that Job A is "mapped" because COMCON called SVEUB
(note that COMCON has effectively done a DATAO page for page X).
a disk interrupt happened.
6. Assume the swapping I/O to bring job A's UPT into core has already
happened. But assume also that SWPINT hasn't been called to point
the new UPT at itself, so the new UPT points to page X.
7. MKADD called for the disk interrupt for job B now checks USJOB and
finds that it's the same since .USJOB is mapped through job A's new
UPT which still points at the page that job A used to have as its
UPT (page X).
8. The monitor gets confused and things go downhill from there.
[Cure]
Point the UPT at NLUPMP just before swapping out. Fix MAPBAK to
know how to deal with this.

Undeserved NXM/parity sweeps on users who are spying on the monitor's hiseg.
[Diagnosis]
If the user spies on us, and we subsequently move our hiseg, and then the
user references the spy page, the user has a stale copy and hits the page we
gave up on.
[Cure]
Change 'virtual' spy pages to be truly virtual by mapping them through the SPT
and the monitor's own section map pages. This has the side effect of growing
the SPT by about 40 words (sigh), and making all entries within monitor section
maps have PM.PUB lit. However, the section pointers themselves (.E?STB) still
have PM.PUB clear, so we will continue to run in kernel mode as required. The
public bit is only there for the user mapping. Fix assorted minor & unreported
bugs with virtual spy pages & not checking them out correctly while we're in
the area.

MCO: 11976 Name: RCB Date: 2-Apr-85:09:42:17
[Symptom]
Problems with SICK & DIE:
BUGINFs do not store their names, etc., as the last stopcode type.
'NODUMP' stopcodes have no time-stamp & annoy users on -20F lines.
'NODUMP' stopcodes type out as 'monitor errors' when in fact they are not
errors, but only interesting occurrences.
[Diagnosis]
SICK is still sick.
Excess call to SVPPC.
Misleading format in the stopcode typeout.
[Cure]
Merge SICK into DIE, and make DIE's processing table-driven. Via these
tables, make sure that events and NODUMP stopcodes do not call SVPPC.
Change the format of the STOPCD typeout from
<bells>
?CPU1 monitor error, STOPCD name is FOO
...
CPU status block on <daytime>
...
where the CPU status block gets skipped for 'NODUMP' types,
to:
<bells>
?Stopcde FOO, type=DEBUG, on CPU1 at <daytime>
...
CPU status block
...
where the CPU status block still gets skipped for 'NODUMP' types.
Also, since 'NODUMP' was originally proposed as 'INFO', add INFO as a
synonym for NODUMP, and have INFO be what comes out as the STOPCD type in the
above format.
As a side-effect of merging SICK into DIE, STOPCD type EVENT is now the same as
a BUG.(INF,...).
The XPCW CROAK mechanism is still not being used, because enabling it causes
problems with returning from stopcodes (even those called by PUSHJs).

[Symptom]
Phase IV DECnet doesn't work on the KS10.
[Diagnosis]
Not enough address space for buffers and names.
[Cure]
Create an alternate map which will be used while executing DECnet
code. This map will be 1:1 with the regular monitor map except for
SYSSIZ=>whatever is required for DECnet buffers and name space. Whenever
a DECnet UUO is executed, when the once a jiffy code or once a second
DECnet code is called, and whenever an interrupt occurs on the DECnet
PI channel, switch to the alternate map. Also teach DNADLL about KDPs
DMRs, etc. Finally, reduce the amount of virtual address space allocated
for PAGTAB/MEMTAB/PT2TAB to 2K (enough to represent 1 Meg of physical
memory).

PG.IDC (PA.IDC) isn't complete.
[Diagnosis]
No code.
[Cure]
Add code. This allows PG.IDC to work for create/destroy section
and create/destroy spy pages. It won't work for move/exchange due
to some constraints on the way move/exchange works. Note that
in each of these cases the desired final effect is what happens; in
particular for the create functions, if the page or section already
existed, it is effectively deleted and replaced by a new section or
spy page. This is slightly different than for page create/destroy
pages which do not zero the old page if you try to create on top
of an already existing page.

QUEUE. UUO can block a job forever, but some functions (e.g., to ACTDAE) can

[Diagnosis]
No timeout facility.
[Cure]
Yes. Add field QF.HLN into word .QUFNC (77B17 in word 0). If non-zero, this
is the total length of the header. If zero, as currently required, assume a
three word header for backward compatability. Any words which are absent will
be assumed to be zero, including the *new* fourth word: .QUTIM.
Word .QUTIM is the number of seconds to wait for a response before aborting.
A timeout value of zero means to wait forever (just as now). If the request
does time out, error QUTMO% (11) will be returned.

Power fail restart on the KL doesn't.
[Diagnosis]
Power fail code eventually wanders into APRRES, either
directly if a transient failure or via RSX-20F when -20F
executes the instruction in location 70 when power comes
back. APRRES calls SYSTR0 to set up mapping, which sets
the SPT to the null job. When we eventually dismiss the
interrupt we get wierd stopcodes or halts during restart.
In addition, in 7.03, we set up a PDL via a MOVEI P,xxx.
This doesn't work when we wander into section 1 when DTESER
calls TTDRLD which calls ...
[Cure]
Restore the SPT at APnRES. Set up a real PDL where the
power fail code needs it. Use an ADJSP to skip over the
words on the stack we've stored data into.

REFSTR and ONCMOD are too unforgiving.
[Diagnosis]
Too many HALT stopcodes which can be STOP stopcodes.
REFSTR can't recover after a stopcode even though it tries.
Confusion over which unit/structure had problems when using
the DESTROY option.
[Cure]
Get rid of the HALT stopcodes and make them STOP stopcodes.
It's very annoying when the KL halts and you don't know why.
None of those conditions warrant a halt (and in fact, most could
probably be made DEBUG stopcodes).
Clean up stopcode recovery in REFSTR.
Make more extensive use of DIESTR and DIEUNI in stopcodes.

[Symptom]
KS too big and too slow, EDDT about right but too fast.
[Diagnosis]
We were in a hurry.
The hidden symbol table stuff for the KS alternate context maps was kludged.
[Cure]
yes.
1. Remove the CDB locations for the map pointers. This allows FILDDT to use
1,,addr to unconditionally get a normal context address, and 2,,addr to
unconditionally get a decnet context address, since the alternate map pointers
now live in SECTAB.
2. Remove the horrible kludge for fudging the EDV for symbol pointers. Instead,
add another sub-block to the EDV's symbol swap list to cause EDDT to force
normal context when poking at the symbol table. This eliminates overhead in
the monitor, and places it in EDDT where it belongs.

[Symptom]
1. BBFIT gets zeroed too many times.
2. BBFIT doesn't get zeroed enough. Actually, what ends up happening
is no background batch jobs ever get swapped in.
[Diagnosis]
1. Too many places indiscriminately zero BBFIT when
zeroing FIT, but they aren't necessarily the same.
2. If there is a collision on the high seg a background batch job
is using, we go away and forget about the fact that we brought this
job into core. Normally, we'd just scan it again at some later time,
but since the swapper only lets one background batch job come in per
background batch swap interval, we won't ever scan it again since the
interval doesn't really start until the current job finishes coming
in (which it didn't because of the collision on the high seg).
[Cure]
1. Don't zero BBFIT unless BBFIT=FIT when zeroing FIT.
2. Add a new linked list queue, linked through JBTJIL and headed
by JBTHSQ. This is a queue of all jobs waiting for some high seg
to finish swapping in. After clearing out all completed SWPLST
entries, scan the queue for jobs waiting for a high seg and complete
bringing any in which can now be completed (or set up to swap in the
high seg for those jobs if it already went out again or managed to
be on the way out when we checked before). Jobs get placed in this
queue if FININ says swapping I/O is in progress for the high seg.

LOKCON doesn't; stopcode CMU.
[Diagnosis]
When moving pages to LOKCON's queue, we keep track of the number
of pages in said queue via LOKHOL. These pages aren't included in BIGHOL
or CORTAL. CHKTAL attempts to compensate for this, but LOKHOL, which
actually corresponds to BIGHOL, isn't really the right thing to compensate with.
Unfortunately, the right thing doesn't exist.
[Cure]
Invent LOKTAL, which is the equivalent of CORTAL, and compensate
with that.

Add .QUCAT (16) to talk to CATLOG. Sub-blocks used are:
.QBVSN ;Volume set name (required)
.QBMFG ;Flags (QB.DSK,QB.TAP,QB.DTA) (optional)
Both block types already exist. However, QB.DTA is new.
Its previous non-existance was an oversight (unsupported code, after all).
The response block returned by CATLOG is described in CATPRM.MAC.

[Symptom]
Most obvious symptom is a tape drive stuck in EW; other
scenarios possible.
[Diagnosis]
Spacing operations don't block, yet call SETIOD when
they are finished. Since the user gained control as soon as the
operation was queued (rather than after it finished), he could
have queued up some I/O for us to do, and the call to SETIOD
for the spacing operation, releases him from his I/O wait.
This can allow two queued protocol requests to get in the queue,
which can cause the drive to hang.
[Cure]
Don't call SETIOD on spacing operation completion. CLOSE
which used to exit through here does need SETIOD called, so
give CLOSE a separate interrupt handling routine.

Job stuck virtual 'cause .UPANA is wrong.
[Diagnosis]
If we are paging in a page with access allowed off AND there
isn't enough core in core to just page in the page, we set up for
expansion and swap the job out and in again. Unfortunately, we also
turn on AABTAB and the accessibility even though AABTAB might have been
off before. We don't, however, decrement .UPANA.
[Cure]
Don't turn on AABTAB (PM.AAB in 7.03) if it wasn't on and
we are paging in (as opposed to creating).

1) Remove it. /USE:1 will work the same as USE:n for n.GE.2.
2) Add the /USE value to the section numbers in the EXE file. This
means that for the most part, EXE files should be for section 0 to

2) If you XCHNGEd RA60s you'd clobber the KDB and spread the
UDB over never-never land (7.03)
3) If units are busy you have to keep trying the command until
you happen to type it at the right time (7.02/7.03)
4) Code doesn't work well for dual-ported disks (7.02/7.03)
[Cure]
1) Don't let the dummies do this
2) Use UNYKOF as the "KONTAB" offset rather than UNYPUN
3) SLEEP until units are idle
4) DETACH alternate ports, exchange the data, then ATTACH the
alternate ports

ROUTER doesn't.
1. Verification failures, confusion. (Sound familiar?)
2. We send illegal phase III TI messages.
3. No way to specify a transmit password.
4. Circuit timing is VERY wrong under certain moon phases. Point-point
circuits come up VERY slowly, or not at all. Broadcast adjacencys work only
on "error free" ethernets.
[Diagnosis]
Yes.
1. The Phase IIIE MCO never made it to 7.03.
2. We don't know what sort of INIT we're sending, so we always include Hello
timer. This will cause paranoid Phase III nodes to recycle the line.
3. See 1.
4. Lots of code added to ROUTER for phase IV thinks that T2 is preserved
across calls to DNGTIM. It isn't for TOPS-10. This results in
inconsistent routing databases, overhead, and grey hair.
[Cure]
Yes.
1. As with the 7.02 MCO, require verification of the remote node only if we want
it. Not if we think HE wants it.
2. Don't include the hello timer value unless the init is > phase III
3. Add one. This time, it is a MONGEN question, asked after DECnet area/node #
You can specify a 0-64 character ASCII string.
4. Don't let DNGTIM trash T2

Can't change size of DECnet, SCA, Ethernet, LAT, or KLNI bit
mapped free core by redefining the "MONGEN" symbol via MONGEN.
[Diagnosis]
All of these symbols get redefined within COMMON to round them
up to the word boundary (of bits). Nobody does this in any of the other
common modules.
[Cure]
Change the MONGENable names to the following:
Old name New name Description
DCNSIZ M.DNSZ DECnet free core size
SCASIZ M.SCSZ SCA free core size
ETHSIZ M.ETSZ Ethernet free core size
LATSIZ M.LASZ LAT free core size
KNISIZ M.KNSZ KLNI free core size
The old names xxxSIZ are the actual size of the free pools (rounded up
to word boundary). Since M.xxSZ isn't redefined, you can't get any
multiply defined globals.

KNILDR runs and runs and runs and ...
[Diagnosis]
If KLNI free core has disappeared, then KLNI initialization
will fail (KNIKAF usually). When this happens, since initializatio
hasn't finished (and the time when the KLNI was stared hasn't been
updated), it requests another run of KNILDR. Also, if the system
has decided not to run KNILDR for one of the KLNIs, and the other
KLNI croaks, KNILDR get carried away and reloads both of them.
[Cure]
1) Reset the time when the KLNI was started when we first start the KLNI,
not when initialization completes.
2) When we start the KLNI, clear the reload request flag.
3) When KNILDR sets itself up as the reload job, clear the reload
request flag.
4) Add another bit to the status word returned by the .KBSTS function
of KNIBT. This bit is KS.RRQ (020000,,000000) which means that
KLNI reload has been requested by the system. Use this in KNILDR
to not reload everything in site when run on FRCLIN.

Bizarre "524292 hard read errors" in magtape usage statistics
when switching tape volumes.
[Diagnosis]
Monitor isn't at fault for the wierd numbers, it's QUASAR,

In TPMLSU, when we know the volume switch will succeed,
send QUASAR a magtape deassign statistics message for the old
unit, but lite a flag bit so QUASAR knows it not a "real" deassign,
just stats for the unit being switched from.

[Symptom]
System hangs when reloading if it doesn't know the date and time,
and there's no OPR to tell it.
[Diagnosis]
It isn't possible to use Primary protocol to ask -20F for the
date and time when we need it. But thanks to the -20F developer, and not Tooo much prodding from us, we can now use secondary protocol to get the
date and time.
[Cure]
Teach ONCE to default all the date and time answers. Default the
date and time questions to what we get from -20F if -20F will talk to , and the validity flag is on. Since it's possible that one FE has a valid
date and time, and some other does not, ask all possible CPUs to poke -20F
for us. Accept the first one that responds with valid data. For the KS,
do something different, unsupported, but equally helpful. While in the code,
make it easier to add the common site mod of confirming date and time. Add
the (normally OFF, UNSUPPORTED) FTDTCK feature test which does what internal
sites are used to.

[Symptom]
If a newly formated pack is mounted and the operator
chooses not to write the HOM blocks at ONCE time, but instead
does it with TWICE, PULSAR cannot mount a structure using said
pack.
[Diagnosis]
By default, all units are marked as having a pack
mounted during ONCE. When a unit is found to be off-line, the
status is changed to "no pack mounted". If the operator chooses
not to write the HOM blocks, the status is left to "pack mounted"
when it should be changed to "no pack mounted".
[Cure]
Set "no pack mounted" status appropriately.

[Symptom]
When many stopcodes happen in succession, SPEAR may only
report the correct information for the last one.
Even that information is wrong.
[Diagnosis]
During stopcode processing in DIE, the monitor
queues a request to DAEMON to log the stopcode info in ERROR.SYS.
DAEMON gets most of its info by PEEKing the monitor when it gets
scheduled. If there are several stopcodes in a row (especially
EVENT or INFO types), then DAEMON never sees the monitor info for
any event but the last one. Additionally, DAEMON always records
CPU0's AC set 0 only, even if some other AC block was actually active
at the time of the stopcode. DAEMON also uses some historical
location to read the PI status at the time of the stopcode. The
info isn't in that location any more.
[Cure]
Have the monitor create its own entry to be put into ERROR.SYS
using the system error block mechanism. Record the AC block which was
active at the time of the stopcode (according to .CPACA). Use the
contents of .CPCPI as the PI status at the time of the crash.

[Symptom]
"Alocatable" LDBs in use by DECnet NRT/CTERM may get lost.
ANFWLA stopcodes.
[Diagnosis]
When a NRT terminal disconnects (or otherwise dies), NRTSER tries to
be clever and notices that the LDB is VTMed away and tries to disconnect
the VTM link (which it does successfully). It then seems to forget about
the LDB, never calling the FRELDB routine to return it to the SCNSER free
pool.
If a LAT terminal is ANF SET HOSTed out, and the LAT service breaks
(User breaks the connection, LAT server or Ethernet goes down, etc.),
the LAT terminal (LDB) is freed (FRELDB) but the ANF VTM connection is
not disconnected. The next time that LDB gets used for any type of ANF
connection (incoming "MCR" or outgoing "VTM") then NETSER finds the
LDB in already in NETLAT, yielding an ANFWLA crash.
[Cure]
Don't worry about ANF/VTM wierdness in NRTSER, instead teach FRELDB to
worry about "other networkedness" of LDBs, and do all the right things.

won't affect anyone calling STOTAC, it will just make it behave

on the new unit class quantity. This enables a customer
to write a spooler which passes the unit class info to

[Symptom]
Stopcode IME, illegal address in UUO, doing both input and output
to a single DECtape.
[Diagnosis]
DEVEVM is getting timeshared for input and output. Unfortunately,
it can't be timeshared, so sometimes we get confused over which
buffer is mapped in EVM and either give an illegal address error
(if lucky) or an IME stopcode.
[Cure]
Change UUOCON so it can only open a single DECtape on one channel.
Trying to fix EVM handling so we can have both input and output EVM
would be a real pain.

If you're spooling to magtape using LPTSPL and the tape drive drops
off line, putting the tape drive back on line has no effect. The
job running LPTSPL is still waiting for an on line interrupt.
[Diagnosis]
TAPUUO gets called when a drive comes on line, and it tells the
MDC, but the information never gets passed on to the job which owns
the tape drive.
[Cure]
Teach TPMONL to call PSIONL as well as SNDMDC so the interrupt
gets back to the job owning the tape (if any).

[Symptom]
Monitor locations 0-177 get sprayed when trying to read a CI
disk with LOTS of bad blocks.
[Diagnosis]
If there are so many bad blocks that the HSC runs out of blocks
with which to do bad block replacement the I/O error will get
passed along to the monitor, which remembers the block number.
When we close (delete) the file, the monitor will scan the bad
block (region) to count the number of bad blocks. It does this
by calling MAPIO with an IOWD with an address portion of zero.
This type of IOWD indicates no transfer into memory is to be
done. That is, except in the case of the KLIPA. The KLIPA is
actually doing one blocks worth of input starting at monitor
address zero.
[Cure]
Teach TSTBAD about CI disks: if a CI disk, get a buffer to
read the block into, and return the buffer when done. This
really isn't needed that often, but if a CI disk starts to go
bad it would be nice to record some bad block information.

[Symptom]
The terminal "APC" value for local (RSX-20F, KS-10 DZ) dataset
terminals always says "hardwired" (.TOHDW) rather than "dataset"
(.TODSD) terminal.
[Diagnosis]
SYSINI calls LDBINI before calling LDBCLR, which results in the APC
value being calculated and set before the dataset status of the
terminal has been determined. This results in a local terminal always

Make LDBCLR initialize the APC field for the LDB. Remove the FTNET
conditional code in APCSET since all network-virtual-terminals (both
ANF-10 and DECnet/NRT) will always calculate and set the APC value

[Symptom]
Possible stopcode KAF when setting large amounts of monitor
memory off-line. More likely to happen in 7.02 than 7.03.
[Diagnosis]
When monitor memory is set off-line LOKCON moves all monitor
pages around during one clock tick. Due to how expensive PAGFRE
is in 7.02 this can easily take more time than RSX-20F thinks we
should be ignoring his keep-alive counter. The more memory you
try to set off the greater the chance of this happening.
[Cure]
After moving each page check if the second timer has expired,
and if so, exit the loop. This will cause the once/second code
to be executed, preventing RSX-20F from causing a KAF stopcode.

[Symptom]
Refreshing a pack on a KS from once only yields a WTP stopcode.
[Diagnosis]
ALSAUN calls HIACLU to allocate the SYS: directory, who calls TAKBLK, who
calls NEWSAT who calls SATWRT who calls MONWRT. Unfortunately, no one
has ever patched PWAIT1 to ONCWAT, so we call CLOCK1 to wait for the I/O
to complete. The reason that this doesn't happen on KLs is that KLs have
FTMP turned on, in which case we don't call MONWRT, but REFWRT (who calls
OMONIO, who DOES patch PWAIT1) instead.
[Cure]
Make HIACLU patch PWAIT1.

[Symptom]
LOGIN recomputes disk usage when it shouldn't.
[Diagnosis]
UFDSET uses a GOBSTR UUO to check if any other job has the
structure in question in their search list. If this is true,
UFDSET assumes recomputing is not necessary. If this is not
true, and RIPLOG is set, UFDSET will go ahead and recompute.
Problem is, the GOBSTR UUO fails when specifying a job number
which is not logged in. If two people try to log in under the
same PPN at the same time right after a crash, each will have
decided to recompute the same structures.
[Cure]
Remove the test in GOBSTR. Change LOGOUT so it will remove
structures from the JSL as they are processed while the UFD
is still interlocked. This will prevent any races which might
allow a user to log out over quota.

SCERR macro in DECNET doesn't leave as many traces as it should.
[Diagnosis]
SCERR generates a JRST to an error routine, so we can't tell
where the error was first detected.
[Cure]
Change JRST to be JSP CX, so that a clever system programmer can
set a breakpoint at the error routine to determine the source of the error.
Also make SCERR check for more popular aliases for CPOPJ so that it
will not generate an extra JRST CPOPJ.

[Diagnosis]
Too little interlocking on the code to typeout the messages. Too impatient

counter even if no characters have been typed yet.
[Cure]
Try harder to interlock the message typeout. Always make COMCON defer the
message handling to SCNSER. Add a 1.5-second slop factor the time we wait
for the typeout to finish before allowing the next SEND ALL.

[Diagnosis]
No code.
[Cure]
Add code. Also, table drive the "see if I own this resource"

earlier.
This adds the following routines:
UPCX - obtain the CX for job in T1 on behalf of job in .CPJOB,
blocking if it isn't available.
DWNCX - return CX job which job in .CPJOB owns.
GETCX - obtain CX on behalf of the current CPU; skip return
if obtained, non-skip otherwise.
GIVCX - return CX for current CPU.
GGVCX - coroutine to get the CX and give it up on return
(via UPCX and DWNCX).
OWNCX - skip if we own CX in some flavor.
Teach KILPDB and IPCLOK/IPCULK to use CX instead of MM.

other CPUs use the memory just allocated.

[Symptom]
Stopcode NSS refreshing a structure if someone selects the maximum
swapping space on a unit AND they tell ONCMOD to put the swapping
space at the end of the unit.
[Diagnosis]
The last SAT must have at least one free cluster for the SAT
itself to be marked. ONCMOD doesn't ensure this, and if swapping
space is larger than the actual number of blocks in the last SAT
(remember, the last SAT will have some non-existant blocks in it
since the unit size is usually never evenly divisible by the
blocks/SAT) the entire last SAT can be taken for swapping space,
causing the NSS when REFSTR tries to allocate a cluster in the
last SAT for the SAT itself.
[Cure]
Teach ONCMOD to allow for a free cluster in the last SAT when it
computes the highest logical block for swapping. This is only
necessary for the odd case described above.

[Diagnosis]
TOPS20 turns on SV%WRT+SV%SHR (page is writable and sharable)
in the EXE file directory to indicate the page is copy-on-write but since
TOPS10 has no notion of a sharable writable page, it says bad directory
for EXE file.

EXE files to be moved to TOPS10.

System will not talk to MCBs.
[Diagnosis]
When I changed %RTBSZ via MONGEN a while back so we could use
1400 byte messages on the ethernet this broke MCBs. It turns out
%RTBSZ is used with two different meanings: 1) executor block size,
and 2) maximum data link buffer size. TOPS-20 SETSPD program pokes
the location where "maximum data link buffer size" is stored to get
the system to use large messages on the ethernet.
[Cure]
Invent a new MONGEN symbol:
%DLBSZ Default maximum data link buffer size
Its default is 576 (just like %RTBSZ) and it governs the size of
the maximum messages that DECnet will use at the data link layer.

[Symptom]
SAVE of a large virtual program is too slow (1 of n). In fact,
I'm not sure that with the current algorithm, that the SAVE of a 16384
page program would complete in my life time; it certainly wouldn't in
the longest recorded uptime of any known system running TOPS10.
[Diagnosis]
1) The image size is immediately expanded to CORMAX causing it
to swap a lot
2) Since the image size is at CORMAX, any attempt to page in a page will
probably require a swap out to allocate the core
3) If a page must be paged out to page in the currently needed page, the
algorithm always starts looking at page zero for a page to page out. This
can take a long time if the only pages in core are high in the address
space
[Cure]
Modify the algorithm to always page out the last page paged in (if known).
This keeps the image small, eliminates the need to search for a page to page
out, and ripples through the core image from page 0-the top which is the
desired effect.

GET/RUN of large virtual programs is too slow (1 of 1?, I'm

[Diagnosis]
SEGCON doesn't do the I/O and/or the paging as efficiently as
it could.
[Cure]
1) Have SEGCON always (unless overlapping the EXE directory page)
setup to read all the pages described by an EXE directory entry. Let
MONPFH handle the I/O, paging.
2) When the I/O is done, always page out the entire glump of pages read
with PG.IDC turned on (this tends to minimize swapping while the GET is
in progress)

[Symptom]
No legitimate way to determine the "ethernet channel number" for
an ethernet channel id using the ETHNT. UUO.
[Diagnosis]
Not returned by any of the functions.
[Cure]
Add "ethernet channel number" to data buffer returned by the ETHNT.
function .ETRCI (read channel information). This word is at the front
of the block and shifts the remainder of the block down by one. New
format is:
Symbol Offset Name
.EICNM 0 Ethernet channel number
.EICEA 1-2 Current ethernet address

The format of the data buffer returned by the ETHNT. UUO function
.ETRCI has changed. A new word (.EICNM=0) has been added to the front of
the buffer. This word will contain the ethenet channel number. Word
.EICEA has been shifted down one word and is now offsets 1 and 2.

[Symptom]
DECnet memory allocation either pre-allocates too little or too
much. Running DECnet on the ethernet makes predicting the amount
of memory to give DECnet at startup hard to do. Customers usually
have to change the default amount allocated (M.DNSZ).
[Diagnosis]
Yes. Bitmap memory allocation is inflexible.
[Cure]
New: Add support for extensible bitmap memory. Extensible
bit map memory is managed by new routines in CORE1: GTXWDS and
GVXWDS which are called just like GETXWS/GIVXWS with the addition
of T3 containing the address of an allocation control block.
The ACB (allocation control block) has information about initial,
incremental and maximum memory allocation. This block also keeps
track of the current free amount and enforces limits on the max-
imum size to which the free pool can grow. The extensible bitmap
memory is implemented as a chain of bitmaps.
Several new MONGENable values now exist:
Name Default Description
M.DNCS 4 Size of chunks in words
M.DNSZ 30000 Initial size of DECnet allocation in words
M.DNTH 4000 Threshold allocation in words
(Point at which pool is expanded)
M.DNIN 4000 Incremental allocation in words
(Minimum amount pool is expanded)
M.DNMN 10000 Minimum allocation in words
(Target amount free when pool is expanded)
M.DNMX 100000 Maximum allocation in words
(Maximum size to which pool can expand)
Customers should normally only change M.DNSZ (initial allocation) and
M.DNMX (maximum allocation).
GETTAB table entires %DNLOC and %DNPTR are now obsolete. New GETTAB
items:
Name Table Item Description
%DNACB 170 23 Address of DECnet Allocation Control Block
%CNACB 11 202 Address of First Allocation Control Block
%CNAHB 11 203 Address of First Allocation Header Block
New stopcodes:
Name Module Type Description
CORNAH CORE1 DEBUG No allocation header block
CORCNA CORE1 DEBUG Core not allocated
CORNCB CORE1 DEBUG Not on a chunk boundary
COMCWA D36COM BUGCHK Core allocation wrong

[Symptom]
MAPIO on the KL can be minutely faster. The calling sequence
documentation leads one to believe the frame-count argument is
only used for DX10 channels. The restriction on IOWDs which
look like RH20 jumps should only apply to RH20 channels.
[Diagnosis]
Replace two instructions which fetch/test CHB22B with a test
on U (already set up from CHB22B). Change the documentation
to reflect reality. Change the restriction to only apply to
RH20 channels.

[Symptom]
Bringing up a system using the startup option switch /NOPRIMARY
doesn't last across warm restarts, MOS memory errors, or power
fail recovery.
[Diagnosis]
/NOPRIMARY causes ONCE to patch out 2 calls to STAPPC, one
in SYSINI and the other in COMMON (SPRINI). There are other
calls which don't get neutered.
[Cure]
Rather than increase the number of calls to neuter change ONCE's
handling of /NOPRIMARY to set a flag (ST%NPP) in CNFST2 which
indicates starting primary protocol has been disabled. Remove
PPCPAT and PPCPT1 to avoid any confusion. While we're at it,
remove the useless JFCL's following all calls to STAPPC (which
only has a non-skip return).

[Symptom]
The concept of a "planned CRAM parity error" on a CI20 or NIA20 is
difficult to understand. People see "CRAM parity error" and assume
something about broken hardware which may not be true.
[Diagnosis]
KLPSER and KNISER print one canned message for planned and unplanned
CRAM parity errors. An unplanned CRAM parity error is a real parity\
error which may be indicative of a hardware condition. A planned CRAM
parity error is simply a way the microprocessor tells the KL why the
microprocessor decided to halt.
[Cure]
Separate out the two cases. An unplanned CRAM parity error will cause
?Stopcode {KLPCPE|KNICPE} blah blah blah
{CI20|NIA20} CRAM parity error
CRAM location nnnn, CRAM contents m,,m p,,p
A planned CRAM parity error will cause
?Stopcode {KLPHLT|KNIHLT} blah blah blah
{CI20|NIA20} microprocessor halted - [reason why it halted]
If the planned CRAM parity error is not one we have defined the reason
will be "Undefined halt code xxxx" where xxxx is the CRAM location.

[Symptom]
It's a pain to debug SMP monitors because:
1. You have to remember to apply SYMS.DDT.
2. You want to use SYMS at a customer site, but you forgot
to take it and the customer doesn't have it.
3. Even if he had SYMS, he never knew what it was for so he
deleted it.
4. Tony deleted cute symbols used by SYMS.
5. It only works if the boot CPU is CPU0.
[Diagnosis]
Yes.
[Cure]
When starting the monitor at DEBUG, store away the CPU number
and have BECOM0 and BRKLOK check it and DEBUGF so calls to these
subroutine can be turned into noops. This feature can be disabled
by putting a JFCL at DDTCPU in ONCE.

It depended on not getting input from BATCON and MIC when running.
[Cure]
Add a new bit to HIBER, HB.DIN (demanding input). If lit, the new
JOBSTS bit JB.UHI (user HIBERing for input) will be enabled, so that BATCON
and MIC will notice that the user job wants input. If HB.DIN is off in the
HIBER request, the old (7.02 and previous) behavior will obtain. To wit,
no input lines will be sent to the job until it goes into TI or exits.

[Symptom]
Symbol table is truncated on large configurations, making debugging
difficult. Some large configurations may not fit in a 256K monitor .EXE
file. Making a TOPL10.REL is more difficult than it needs to be.
[Diagnosis]
A bad case of creeping featurism happened in 7.03. We used up all of
the addressing space available in section zero. As a stopgap measure we
loaded DECnet modules following the rest of the monitor code and played
games to relocate them into section 7 so the addressing space they used
could be re-used by AUTCON for data structures. Putting the DECnet
modules there required tweaking TOPL10.REL and DECNET.REL into one
TOPL10.REL with the DECnet modules in the "right" place. This in turn
made the monitor build procedures more difficult. Unfortunately, we
quickly used up any space which was left over with those new features
like CI and NI and LAT and contexts and ...
[Cure]
As a preliminary to making a real multi-section monitor .EXE file, start
using PSECTs for the high and low segment. In the first incarnation
nothing will actually move. The symbol table will still follow the low
segment, DECnet modules will still load following the rest of the
monitor, and the symbol table will still get truncated on large
configurations.

Section names are inconsistent and not very indicative of what is in a
particular section. Some references to MDSEC1 involve the addressing
space where SAT blocks are kept while others involve the first monitor
data section.
[Diagnosis]
MDSECn was OK when there were only a few things in extended sections,
but now that we are literally all over the place we need to separate
MDSECn into various other pieces.
[Cure]
Split MDSECn into MS.xxx, where xxx is "SAT" for SATs (old MDSEC1),
"MEM" for PAGTAB/PT2TAB/MEMTAB (old MDSEC2), "SCN" for SCNSER's data
base (old MDSEC3), and "FMD" for references to the first monitor data

No room for the sky high segment in a multi-section .EXE file when
loading in 768K.
[Diagnosis]
The sky high segment is currently in section 7. Since BOOT loads a
multi-section .EXE file in place, one would require 8 sections of 256K
to load a monitor with code in section 7. That's a little beyond the
SPD, to say nothing of the limits of reason.
[Cure]
Exchange the section numbers used for the SATs and the sky high segment.
SATs now reside in section 7, and the sky high segment resides in
section 2. By shuffling the sections around we make room for the DECnet
PSECT to load in (physical) section 2 when that MCO happens.

[Symptom]
JMF loops doing SYSPHY UUOs on CI disks.
[Diagnosis]
"Detached", "Second", and "Alternate" ports are handled in
varying ways. The inconsistancy causes problems when trying
to program around the inconsistancies.
[Cure]
Link "detached" and "alternate" ports onto a separate chain
(called SYSDET). Teach SRUNA to look at this chain when a
search is made for a physical unit. "Second" ports will not
appear in either the SYSUNI or SYSDET chains as happens now.

NODE command lies about DECnet nodes when running as an endnode.
All nodes are listed as unreachable.
[Diagnosis]
Yes. System doesn't know if the node is reachable or not,
but since it has no routing information it assumes the node is unreachable.
[Cure]
Yes. If the system is running as an endnode type "may be reachable
via the designated router" instead of unreachable.

[Symptom]
Sometimes, it appears that INITIA doesn't run
on freshly-connected LAT and NRT lines.
[Diagnosis]
INITIA really does run, but doesn't produce any output.
The reason is that the fresh LDB may sometimes have the "offline"
bit set. The reason the bit is set is that GETLDB calls
LDBCLR, which calls a routine through the LDBISR dispatch table
to determine whether a line is "offline". The problem is that
we still have the address of dispatch table from the previous owner
of the line. If the previous owner was ANF, we end up asking if
the line is still connected to some ANF node. ANF responds by
saying "It's not connected. I got rid of that line many ticks
ago.", so we set the offline bit. When SCNSER sees the offline bit
set, it doesn't bother doing output for the line in question.
[Cure]
When calling GETLDB to grab a fresh LDB, provide the address
of the new dispatch table as an argument.

[Symptom]
SNOOPY doesn't quite make it on an extended addressing machine.
When two monitor code sections overlap the PCs get ORed together
which leads to useless histograms.
[Diagnosis]
There isn't enough EVM available to lock as much of SNOOPY as
we'd like to produce finer resolution histograms.
[Cure]
Reserve monitor section 36 for SNOOPY's use. On an extended
addressing KL, SNOOPY will stick a pointer to his section 36
(to be used for PC histogram accumulation) into the EPT of the
CPU on which it is running. This will allow a resolution of
2**2 which should be enough for anyone, as well as allowing a
real histogram for a multiple section monitor.

LPT on the KS doesn't work.
[Diagnosis]
The LPT is on the same PI channel as the KDP; the KDP wants
DECnet context, but the EVM the LPT uses isn't mapped there.
[Cure]
It has been decided that EVM will not appear in DECnet
context (leaves more map slots for DECnet to snarf up). Therefore,
since SAVn for the KS always has to call one of DNMAP or RGMAP
to ensure consistent mapping at interrupt level (never know what
context we may have interrupted out of), give SAVn for the KS a
new set of entry points so that it can be decided at run time whether
to call DNMAP or RGMAP instead of always calling one or the other
for a given PI channel. Entry points SAVn and SAVnR (new) will
set up normal context mapping, and SAVnD (new) will set up DECnet
mapping. Fix the KDP and DMR interrupt routines to call SAVnD.

[Symptom]
Monitor runs with cache turned off after a reload if the patch at
SYSTRT to always run with cache turned on is removed.
[Diagnosis]
REBOOT turns off paging before getting to CP1CRS or RLDMON. At
SYSTRT we expect a CONI PAG, to contain the cache strategy bits.
It does when we first ran KLI, but doesn't after REBOOT.
[Cure]
Add some co-operation between the monitor and BOOT to save
the cache strategy across reloads. Teach BOOT to pass the cache
strategy to the monitor when we would have normally turned the
cache on so the monitor can run with cache on or off as appropriate.

[Symptom]
COMCON prints "??" when a user-defined command is typed after
getting an NZS program. Might do the same thing when a command
is delayed for any reason.
[Diagnosis]
If the command gets delayed we make a second pass through
COMMAND. In this pass SKIPS1 returns junk for the command name
due to a test on P2 versus PLNTXT. The first time through the
command decoder P2 contains zero for the first call to CTEXT,
while the second time P2 contains PLNTXT since we set that up
the previous pass. SKIPS1 sees this and takes the "no characters
left" return to CTEXT, who returns to COM1 with junk in T2.
[Cure]
Remove the test on P2 versus PLNTXT at SKIPS1. This looks like
an early attempt to prevent user-defined commands from doing
a RESCAN past the command which invoked them (left over from
7.02 days).

[Symptom]
Problems with fragmented swapping: IMEs and the potential
to miss swapping in parts of the job.
[Diagnosis]
If we decide the job is fragmented on the disk, but find out we
don't have enough low core blocks to continue a fragmented swap, we arrange
to swap in the first piece of the fragment as if it were the whole job, except
we light FRGSEG in JBTSWP to tell SWPIN3 to come back here when this piece
finishes. Unfortunately, SWPIN3 not only checks FRGSEG in JBTSWP, but
also SL.FRG in SWPLST. The latter check only works if we didn't
find a block to start with, rather than running out
after allocating the first block. It turns out that this is only
a problem if we ran out or core processing section 0.
[Cure]
Instead of checking for SL.FRG in SWPLST, check for J containing
a low seg and SL.DIO being off (swap in of job as opposed to high seg).
High segs will stopcode before ever getting here anyway; if they're
ever fixed, a high seg will probably still never get here (and it's
not too hard to fix even if it does and will serve as a reminder that
other things have to be fixed here anyway if that is ever to work).

Blue air when system runs slow because the cache was turned

[Diagnosis]
No warning if the cache has been disabled.
[Cure]
Add a warning message, to wit:
%%<ding><ding> Cache is disabled< on CPUn>
which will be printed on the CTY if a CPU's cache is disabled.
At the moment this message comes out rather late during ONCE.
Next week I'll see if I can make it happen a lot earlier, like
before we ask for the date/time.
This MCO also adds a routine to SCNSER called CTYERM which may
be called to set up for output to the CTY during ONCE or normal
timesharing, since this is useful in more than just one place
in MONBTS now.

Actually it does, it's just timing out the hung "transfer".
It seems the RH11 returns "non-existant drive" for the FIRST position

RH11 in this case and ignore the interrupt. Ignoring the interrupt
is probably not wise.

[Symptom]
Swapper sort of hung; doing lots of transfers but going nowhere.
Potential for real swapper hung, too.
[Diagnosis]
If a job trying to LOCK physically contiguous in core
has its own high seg in the way of the low seg (which is the only
part being LOCKed), LOKCON will attempt to swap out all low segs
connected to said high seg so that it can eventually swap out
the high seg. It will find that the job trying to LOCK is connected
to the high seg and swap it out, however, when the swap finishes, then
LOKCON will then notice that the job LOCKing in core is swapped out and
swap it right back in, so that the high seg in-core count never
goes to zero. LOKCON ends up swapping the low seg out so it can
swap out the high seg, and then swapping it back in again before
it can decide to swap out the high seg,...
The potential for the real hang is we can check
JS.SIP for a high seg, which doesn't exist.
[Cure]
Move the check for "job locking in core is not in core" until
after we've done all the mucking around with high segs and jobs to
see who needs to be moved around to accomodate the job locking
in core. Since IMGIN, NFYPGS, etc. are always set even when the job
is out, we don't need it in core anyway until then.
Don't check JS.SIP for high segs.

[Symptom]
Lost free core.
[Diagnosis]
When some commands are executed by a not logged job which has no
core, allocated (always one) context block will be lost. This
happens because the a user might have typed something like a DETACH
command. Around PCRLF4, if an error occured in an unlogged in job,
we merely delete the job's TTY DDB, ignoring any thing that the PDB
may contain. When the job slot is recycled, CREPDB finds and uses
the old PDB pointer, and zeros out the entire PDB, thus losing the
context block pointers.
[Cure]
Change command cleanup to call KILPDB. Make KILPDB call a new entry
point in CTXSER (CTXKIL) which will arbitrarily delete any context
blocks that remain. Note that in the normal case of a real job,
JOBKL would have called CTXLGO so all idle contexts would have been
auto-popped.

[Symptom]
Monitor isn't as efficient as it could be when memory fills
up with pages from the paging queue.
[Diagnosis]
If a job (say DTX) is paging madly, all of the pages go
onto the IN queue. Eventually, there are no free pages, since they're
all either in the job's working set or on the IN queue. The next time
any job asks for memory, it will be swapped because there aren't
enough allocatable pages on either the free list or the OUT queue.
At this point we also dump the IN queue anyway. It would be more efficient,
particularly if the job asking for memory (say DTX) is large, if we
didn't bother to swap it out if we could make sufficient room
for it by dumping the IN queue.
[Cure]
Make a new routine, FRDCRW, which will set up to dump the IN
queue and wait until it's done if sufficient memory can be made
by doing this. Call it in the appropriate places. This puts
the job in PQ (Paging Queue I/O) wait. When IP2OUT is called,
requeue all jobs in PQ to RN (PS, but that doesn't really
exist any more) so they can wake up and look for memory.
If enough room can't be found on the IN queues, then swap the job out.

Monitor won't run if BOOT isn't at the top of physical memory.
[Diagnosis]
Code to adjust SYSORG to reflect the presence of BOOT expects
BOOT to reside at the top of physical memory. Consequently, when
ONCE adjusts SYSORG to exclude BOOT it may wind up with a value
which will allow the monitor to allocate pages containing BOOT to
be used for the monitor's (sky) high segment.
[Cure]
If BOOTPA (physical address of BOOT [location 20]) is correct,
stuff that into SYSORG. This will ensure ONCMAP doesn't grab a
page which may contain the bootstrap. The "unoccupied" pages at
the top of physical memory will be reclaimed by KIINI for users.

SPEAR interpretation of software-detected disk errors is
not always right for massbus disk, and is completely meaningless for
CI disks.
[Diagnosis]
SPEAR uses heuristics to figure out what went wrong. When
it sees any kind of disk error, it looks at some counters to see if
they changed since the last entry from the same disk. It then attempts
to report what the real error was. It is frequently wrong.
CI disks don't have useful information in the massbus registers anyway.
[Cure]
When FILIO detects a disk error, set a code in the DAEMON entry
to indicate what part of FILIO found the error. These codes can
often be traced to a specific error like "RIB error" or "Unit offline".

[Symptom]
System having a KLIPA on a non-BOOT CPU but no KLIPA on the BOOT
CPU doesn't always (read that usually) get CI disks mounted during
ONCE.
[Diagnosis]
When CPU1 initiates a connection to the disk server in the HSC-50
we may not have enough memory available for the connection. If
this is the case the message won't be sent until more memory is
made available. When the memory is made available SCASER pokes
KLPSER to send the message, but since we're running on the wrong
CPU we only set the "queued I/O" flag in the PCB for that CPU and
wait until his once/tick code comes along to send the message.
If you guessed that once/tick code doesn't execute when a CPU is
looping in its ACs waiting for the BOOT CPU to ask it to do some
I/O or etc., you're right! Consequently we never do get around
to sending the message until the system really starts timesharing
and the disks don't get mounted.
[Cure]
Bypass limit checking during initialization but still flag we
need to create memory to prevent this hang.

[Symptom]
1) DECnet/KS doesn't when user program is virtual (and we page fault).
2) DECnet/KL too sensitive to load order (revisited).
[Diagnosis]
1) Calls to GETWRD/PUTWRD/CHKBPT and a host of other routines call
the routine in DECnet context. If we page fault, the monitor
tries to forge ahead in the wrong (DECnet) context.
2) Code depends on a fair amount of monitor HIGH segment code to
be accessible via indirect SKY segment map pointers. If high
segment moves, or user loads monitor HIGH segment in a funny
order, then the routines can't be called (except via SNCALL).
[Cure]
Invent macro MCALL which takes three arguments. First argument is
RG or DN (for regular or DECnet) which indiciates which context the
routine is to be called in (for FTXMON off). Second argument is
the section number the routine is to be called in (for FTXMON on),
and third argument is address of routine to call.
Use this macro generously in place of SNCALL and RGCALL in DECnet.
Also, since DECnet uses STOPCD macro, move DIE and PERISH from ERRCON
to COMMON (also routine BGCTYP). And since DECnet likes to run on
SMP, it is now a requirement that CPNSER be loaded after the DECnet
modules and before the remainder of TOPS10.REL so the SMP interlock
routines are available.

[Symptom]
Some random location in the monitor low segment gets the value of
PAGSIZ stuffed into it.
[Diagnosis]
Complex polish definition of WSBTBL in S.UNV causes MACRO confusion
when it is compiling VMSER.MAC. When MACRO reads the universal file
and inserts it into the symbol table it screws up the definition of
PAGSIZ, causing the start of the fixup chain for PAGSIZ to point off
into the boonies. Later, when the monitor is linked, LINK does just
what MACRO tells it to do and stuffs the value of PAGSIZ into the
location addressed by the bad fixup chain.
[Cure]
Polish in universal files is iffy, at best. In fact, an answer to
a SPR complaining about such a problem was marked as a restriction
in MACRO.
By using some minor magic in the definition of WSBTBL we can change
the definition from full-word polish to right-half polish, which is
enough to keep MACRO from shooting himself in the foot.

[Symptom]
Tape subsystem hangs occur in SMP configurations, most often when
MDA controlled tapes are being used. When this happens, the user job
or PULSAR will often be seen in Event Wait for the tape controller.
Occasionaly, either job will be stuck in IO. Sometimes this will
lead to a hung device condition. Stopcodes KSW, USW, and erratic tape
subsystem behavior may also be experienced.
[Diagnosis]
There are flaws in the queued I/O mechanism used to cause I/O to
happen on a CPU other than the one on which the job is currently
running on. This is evident by the fact that CPUTPQ (the system-wide
count of queued I/O requests) will be incremented but sometimes does
not get decremented to zero. When CPUTPQ remains positive, it
indicates that some queued I/O request was not satisfied (no interrupt
call to TAPSCH) and a job has been left in some I/O-related wait
state.
Additionally, bit IOSCP2 in AC S does not always get initialized
correctly for the tape scheduler prior to determining whether or not
queued I/O will be done for the IORB in question.
[Cure]
Do not count up the queued I/O request counts for the current CPU
if no IORB is present. It's quite possible to get to PCLTAP without
an IORB. Also clear IOSCP2 prior to calling the tape scheduler. Note
that although this patch is generated against the 7.03 monitor, it may
be applied without any changes to either the 7.02 or 7.01/7.01A
monitors.

[Symptom]
Trying to run a non-DECnet monitor in the minimum amount of
memory as specified in the SPD fails with a MNM stopcode
(monitor memory non-existant).
[Diagnosis]
MCO 12766 wasn't paranoia, it was a necessity. Map slots
for unused sky high segment pages must be cleared otherwise
KIINI gets confused when one of those pages (which may be
occupied by BOOT or hidden symbols) is marked in NXMTAB but
also is used for the regular high segment.
[Cure]
Install MCO 12766 as one of the "required" edits for 7.03.

[Symptom]
UFD corruption. RENAME error 22 when logging out. Data blocks of the
UFD get overwritten with garbage entries which turn out to be a RIB for
some file not belonging to that user.
[Diagnosis]
Blocks are retained in the monitor I/O cache after those blocks are
freed up by calling GIVBLK. RIBs for deleted files can be found in the
cache. If a user logs in and LOGIN creates an UFD for the user those
blocks can be re-used for the UFD. The usual case involves a RIB for a
temporary file which ACTDAE creates when the user logs in. When the
user logs out ACTDAE deletes the file, but the RIBs are still in the
monitor I/O cache. If LOGOUT deleted the user's UFD the next time the
user logs in they may be allocated the blocks which previously contained
RIBs for ACTDAE's temporary file. If a file is then created the monitor
will mistakenly believe the UFD data is contained in the cache, compress
the bogus UFD block(s), and add an entry for the file being created.
The user is rewarded with a handful of RIB errors.
[Cure]
Whenever GIVBLK is called call CSDELR to flush any blocks in the range
being returned from the monitor I/O cache.

[Symptom]
Stopcode KAF running DFPTA (and maybe other KLIPA diags).
[Diagnosis]
KLPSER is clearing the bits to test for on interrupt when
the KLIPA is set into maintainance mode. Unfortunately, a
tortuous path through the code has managed to stomp on P1
which is being used in the SETZM to clear the bits.
[Cure]
Reload P1 before the SETZM.
