This is a problem by itself, but more so if fsclient is run as a child of itself as in the default stpgm currently:
fs/st.default/control/stpgm.ctl
Line 6 in 71df302
This results in two windows being opened for every window managed by fsserver. (This was frustrating to track down!)
Such uses cases my be better covered by using ssub directly anyway, especially once #25 is merged.
This prevents, for example. the .snp
file from working as is for a BB test with no recorder.
This can probably be fixed with something like:
+++ b/drudg/snap.f
@@ -1091,7 +1091,7 @@ C prior to this scan. Do only on a new pass for continuous.

endif
- if(km6disk) then

csetup_name="setupbb"
else
call setup_name(ccode(icod),csetup_name)
After a successful make, when doing a check 'make' to see if there are any problems, we get some extraneous output that might cloud the issue:
make -C oprin
make[1]: Entering directory '/usr2/fs-10.0.0-alpha2-11-g352e0da7/oprin'

Makefile:59: warning: ignoring old recipe for target 'clean'
make[1]: '../bin/oprin' is up to date.
oprin does work
While investigating #22, it became clear that the output display and logging for the TNX command uses logit()
, creating a risk of a possible deadlock.
Background: The TNX functionality was added in 08249d9 (2001 Feb). In 54af15c (2016 Jul), ddout was fixed to not use class I/O with fserr, sterp, and erchk to eliminate the risk of a deadlock in high log entry volume situations, like multicast logging. However TNX use of logit()
and reporting error bo -999
(also usinglogit()
)were apparently overlooked; they are still vulnerable to this. Probably only cls_snd()
was looked for.
Still, the chance of a deadlock is pretty low. It could probably only happen in a high volume situation (active multicast logging) if the operator either uses TNX or changes to an existing log file big enough to cause a warning about its size (bo -999
). Even then it is probably unlikely that the class I/O system would be at maximum capacity.
It looks like the most straightforward way to fix this in ddout.c is probably:
logit()
The particular bo
errors reported by ddout
would probably forego being filtered by TNX and sent to sterp and erchk, but with more code rearrange probably could be fully supported.
There is no make dependency on the VERSION/RELEASE information. So the information in the executables could be stale. Possible solutions:
Brute force delete the affected .o files on every top level make
Save VERSION/RELEASE information in a file and if different (or missing) apply (1).
Write rules for the affected .o files that will cause them to be remade when the condition in (2) is met instead of using (1),
From #45:
07:29:44?ERROR fm -1 Opening file: /usr2/proc/nothing.prc
07:29:44?ERROR bo -133 Error opening procedure library, UNIX 2: No such
file or directory
Added in a2f6bbc, while removing a non-logged error message when used with the FS, i.e., in a program that is "online". This was being conservative to avoid a silent error in case the caller did not handle the error. In fact, everywhere it is used in a FS online (i.e. not stand-alone), the error is logged normally, except aquir, where it could be fixed up easily (there are lots of other non-logged fmpsee/ errors though). In the case of aquir, this was a by-product of how it was incompletely promoted from an external to an internal FS program in 1ae556d. I can remember both of those errors, but finding them in the history with blame was relatively easy; especially since the second was apparently more about 25 years ago.
If the snap command given to inject_snap
generates an error, the code to print the message back to the user hits an error eg:
$ inject_snap -w blag
cls_chk: illegal class number 0 pid 25020
cls_chk error 1 in cls_rcv()
Seen on both 32 and 64bit FSL10.
For example, running
help=(
Causes a segfault in fsclient
or boss
, depending on running with fs server or not:
23:16:14;help=(
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
...
boss terminated-Segmentation violation
This was the underlying problem in #3.
The shell use allows some pretty trivial remote execution. While it's not security issue right now as we "trust" user input, it might be good to fix this if we want to change model in the future.
In a similar vein, there's also a buffer overrun error here that should be fixed.
Actually it is /usr2/tle_files
FS10 seems to ship equip.ctl with the default lines
* DBBC3 firmware version, bbcs/if, ifs
v223 16 8
According to the Hat-Lab hompage, https://www.hat-lab.cloud/downloads-dbbc3-ddc/, the available firmwares are: 121, 123 (mostly used by e.g. Onsala so far in VGOS obs), 124 (should be 123 with multicast; see #32 ), 125 (experimental)
Therefore I was puzzled by the "223" in the default equip.ctl. Should it perhaps be 123? Also, which firmware versions are currently supported by the FS; is this listed somewhere?
It would be nice to have a facility to suppress metserver (and maybe metclient) error e-mails when their is a known problem, e.g., the device is disconnected, without having to disable it. That way it could recover automatically when it comes back on line.
There might be something fancier that would be better, but a simple approach might be have a file in /usr2/control that the daemon reads. If it doesn't exist, processing is normal. If it does exist, it has a time limit/epoch for how long to suppress the e-mails, including options for indefinitely and until it recovers. Maybe deleting the file would be a simple way for the operator to restore it immediately.

This causes a conflict between 32- and 64-bit operation in fixed length data structures in C and values passed to FORTRAN. This will need to be fully resolved before 2038, only 19 years away.
Short term:
A change in declarations of passed in pointers in rtelb from time_t to int and changes to pass pointers to int to the same routines (and then conversion of results to time_t) in fmset is probably sufficient for now. This is implemented. It needs to be tested in setcl and fmset for:
5B
RDBE
FiLa10G
Mark IV
S2 (no longer possible)
VLBA (no longer possible)
Use of the rtelb routines in FORTRAN needs to be checked.
Longer term:
The use of the int array centisec in dbbcn, rdbcn, mk5cn, (other...cn?), fmset, and setcl (and chekr?) and perhaps others can probably be easily rewritten to use a structure with time_t in C code.
The use in FORTRAN code will be tricker since there needs to be integer4 and integer8 for 32- and 64-bit respectively, and that will also affect the data structure lay-out. Are FORTRAN structures an option?
In principle for model computer
there is no need to have the time since boot limited to 248 days. For 64-bit systems this limit will be expanded beyond being a practical constraint (248 days already seemed long enough for that), but maybe the time code could be restructured to avoid this even on 32-bit systems. Maybe struct timeval
could be used internally instead of clock_t
to represent ticks, but that seems excessive Maybe a 64-bit int is good enough. There is a related issue #56.
Similar to #48, fsclient with the "-n" flag will still create fs.prompt.
This case is slightly more complex however. In principle you could be in a situation with only one fsclient with the "-n" flag set and a blocking "fs.prompt" is called, in which case the client would give no indication as to why the FS has stopped.
Perhaps such a situation is unlikely enough that the right thing to do is ignore it and honour "-n" anyway.
It looks like an "anonymous" method is available with ftp-ssl:
https://cddis.nasa.gov/Data_and_Derived_Products/CDDIS_Archive_Access.html
Which might be a good idea to minimize dependence on a .netrc file in case some sites can't use that.
This (benign) error also occurred on all three systems at Wz right after the year change. The FS at Onsala, at least, had been running since summer.
Note from the attached log (where is it?) that this error was not for the first procedure executed, exper_initi
, typically from the schedule procedure library, but for sched_initi
and clock procedure, typically in the station procedure library. If the field system had not been restarted since the new year, the already open procedure libraries have the previous year’s timestamps. The station library would have been in that state. The log was opened after the year change. The check for a century wrap in newpr.f is not restrictive enough and moved the procedure last log time into the next century, past the 2038 signed 32-bit limit, hence the error:
if(itpr(6).lt.mod(itmlog(6),100)) then
itpr(6)=itpr(6)+(itmlog(6)/100+1)*100
else
itpr(6)=itpr(6)+itmlog(6)-mod(itmlog(6),100)
endif
Tightening up that if
test, should fix it (testing should prove it). OTOH, reseting the procedure time-stamps when a new log is opened should also fix it. The former is probably better.
We probably haven’t hit this case before (or heard about it) since most people probably don’t leave the FS running across the year boundary (once upon a time it was not supported) or they were too busy to report it when it went away after a restart (which resets the procedure timestamps).

Hello Ed,
I hope you had a nice Christmas and New years. I have an FS error question. Earlier this week, when started a schedule I got this error on the OTT-FS machines:
2020.007.10:04:13.90?ERROR bo -257 Internal error: time for prsecs invalid
After restarting the FS the problem seems gone, but I have never seen this before. Could you explain what "prsecs" is, and perhaps any clue to why this error appeared? I haven't managed to track it down to a specific command causing it, but if it happens again it may be useful to know a bit more.
Sometimes a monit program will be started in a window of the wrong size (the user should perhaps edit X resources for a more permanent fix) and resizing does not help.
The monit programs should respond to SIGWINCH and redo their init function.
The day 248 time problem reared its head at WSRT without warning as reported by Richard Blaauw (and subsequently by Jon Quick for HartRAO). This turned out to be because the errors/warning were not enabled if the time model is computer
.
This goes back to traced back to commit f3ee6ea, FS 9.11.0, Jan 23, 2013 , code change made 2012/05/25.
After a few e-mails with Richard, we identified the lack of warning being due to the code incorrectly only reporting the error if the model is not computer
. In principle there is no limitation if the model is computer
, which is why it was not checked. However it should have been checked since the same internal 32-bit logic as for non-computer
models is used for tracking the computer time, for now. Lesson learned: it must always be checked. Related issue #15 discusses the long term solution.

Sometimes schedules aren't available on CDDIS, but are on others.
Maybe the support for other data centers could be à la plog.
I tried running ONOFF with cont_cal=on. Doing this on the 9.12.12 system works, I think because the relevant procedures are defined as
define caloffnf 20128155358
caloff
sy=go onoff &
!+1s
sy=go onoff &
enddef
define calonnf 20128155406
calon
sy=go onoff &
!+1s
sy=go onoff &
enddef
However, following the recommendations in "/usr2/fs-git/help/onoff.___" , I have now (for FS10) defined these as
define calonnf 20171074921
if=cont_cal,,calon
!+1s
sy=rte_go onoff &
enddef
define caloffnf 20171074911x
if=cont_cal,,caloff
!+1s
sy=rte_go onoff &
enddef
I don't remember the logic for the IF statements (is this documented somewhere?), i.e. which call is excecuted if true/false.
I assume from the behaviour in dc6.log that with cont_cal enabled, I don't get any useful tcal signal for the DBBC3. Likely the work in #32 needs to be finished first? Assuming this is the case, I turned cont_cal=off and tried again. Indeed, I now get reasonable values, see attached dc7.log. Should I get reasonable values also with cont_cal enabled? Perhaps I am missing something somewhere?
fsserver
currently needs some /var/run
directories to create unix sockets to
comminucate with client. fsalloc
creates them and sets the group owner to rtx
and permissions for group read and write.
While the group rtx
is used on standard on FSL, it may not exists on other less
supported systems. This will result in fsalloc failing.
Ultimatly I plan to move fssever to use just a single TCP socket which will
remove the need for the directories.
It would be useful to publish the log messages on fsserver too. This will require some code in ddout.

Hi Ed
There's something slightly fishy with TNX. A source set before the end of

And, no the error did not occur in the interim. Logically one should be able to turn an error back on if it appears in the TNX list even if it hasn't yet occurred in the context of the current schedule. What intrigues me most is that initially it wouldn't let me but, after thinking about all night, then
it would! Actually I suspect it was trying to turn it off again that 'fixed' it.
Most of the uses of FS libraries use implicit function declarations, which might be hiding some sleeping bugs --- especially with 64 bit conversion.
A better approach would be to make header files with the function declarations/prototypes and include them when needed. A tool like cproto could help generate the header files from what we currently have. This will also clean up some of those pesky compiler warnings!
We would need to decide how we should structure/arrange the headers. Some options:
include/clib.h
, etc.include/dbbc.h
(maybe these can be merged with the struct definitions that are already there)This is a cul-de-sac of 64bit development that comes off of 9.12.12 used at MGO and at AuScope that could be added to the FS history. Since it has been used in operations, perhaps it should be added.
It seems grub-install assumes the mounted /boot/efi
partition is the one you want to install to, so this line doesn't do anything. Should replace with
check /dev/sda1 is mounted as /boot/efi, then:
grub-install /dev/sda
update-grub
cp /dev/sda1 /dev/sdb1
Entering "help" or "help=", causes a "help=(null)" to be sent to fsclient and then fsclient crashes.
Two things need to be fixed here:

erroring like thatReported by Jun Yang at Onsala.
Thinking out loud ...
So sometimes it is necessary to do development on an operational system. However, you don't want to disturb the repo that is actively being used for operations. Is there a well accepted way to do that?
One possibility is to clone the repo that is being for operations to another local repo for development, pushing to the operational repo for testing (this is assuming you don't want/need to change the link to the repo and reboot to re-initialized shared memory). This gives a way to stage changes and make sure they compile before trying to run them. I have tried that and it seems to work fine.
However, another possibility is to make the development repo the clone of the github repo and make the operational repo a clone of that. This would allow staging changes from the github repo as well without affecting the operational repo. You would pull to the operational system to do the testing.
In either case, you are still disturbing the operation system. but only when testing is possible and if the development is on a new branch the operational system should be restored with checkout - and make.
Maybe it is just better to have a separate repo, a clone of the operational repo, change the link, and reboot. Then you would only push when it is ready for operations. Changing the link and rebooting (twice) is a lot of overhead though.
Are there other/better possibilities? Maybe the above options are ungood git thinking. :)
Using commit fbd0133 :
The ONOFF VAL and SIG lines appar OK, but others have a spurious char inserted after #onoff#, for example:
2020.171.07:34:20.63#onoff#ðAPR ih 9552.00 1.573 371.67 0.027000 1.00000 0.027000 11600.00 p 0.16620

Is this correct? Please see attached logfile dc6.log. Again, it doesn't happen for the VAL or SIG lines, but for the others.
Some field misalignments, particular the third, do not produce visible errors. This can make commands appear to be unavailable. This is particular bad for stcmd.ctl since when it will be obvious at a station why local commands have disappered. A problem like this is more likely to be caught in fscmd.ctl since FS testing before a release should reveal it.

Depending on the skedf.ctl set-up, drudg may want to prompt interactively, currently for tpicd interval and continuous cal control when making .prc files.
Maybe there is some way to pass those "unexpected" prompts to the user for an answer (expect?).
Maybe fesh could have command line options to set those responses or to allow the .prc dialogue to be interactive or something better ...

I might very well be missing some file/configuration/procedure, but I cannot figure out where to start looking. Any ideas?
The main obstacle here is that the user can't pick an arbitrary start time on the target day. However, it would still be useful in some cases to simply rotate a short schedule to a different day.
One sometimes gets warnings about modified holog/MASK/... or holog/mask/... files when checking out old versions. Are they benign? Is there a way to fix that?
Perhaps the group "operators" can run a "send_usr2" command which does the sending tar etc. EG,
on fs1:
visudo
Then edit to add:
%operators ALL=(ALL) NOPASSWD: /usr/local/bin/send_usr2
This allows operators to run that command as root without having to enter a password
On fs2:
visudo
Then edit to add:
%operators ALL=(ALL) NOPASSWD: /usr/local/bin/receive_usr2
%operators ALL=(ALL): /usr/local/bin/refresh_spare_usr2
In refresh_spare_usr2:
ssh fs1 sudo send_us2 | sudo receive_usr2
with
send_usr2 (on fs1):
#!/bin/bash
cd /usr2; tar --one-file-system -cf - .
receive_usr2 (on fs2 with correct /dev/…; also in check if mounted)
fuser -k -m /usr2
umount /usr2
mkfs.ext4 -U $(tune2fs -l /dev/md2 | grep UUID | grep -o '[^ ]*$') /dev/md2
mount /usr2
cd /usr2
tar xpf -
all instead of:
ssh root@mauka "(cd /usr2; tar --one-file-system -cf - .)" | (cd /usr2; tar xpf -)
For VGOS observations using DBBC3, and in particular for source-structure interpretation of the correlated data, we need (continuous) logging of tsys values to a log file during observations.
@wehimwich informed me via email 2019-10-01 regarding this that:
Continuous cal worked, but the communication required overloaded the system. It will have to wait until [DBBC3] multicast is available.
Yesterday I read in an email from Gino Tuccari (DBBC3 developer) that
[multicast is] available the v124 V version, which produces multicast strings and it's just like the version v123 in terms of firmware. [...] I don't think it's compatible one-to-one with the RDBE multicast, because we developed independently, but I suppose this could in some way compared or adapted for the FS.
I have asked Gino if there is an interface document etc. to describe the structure of the multicast. Hopefully the community can work together to adapt the FS10 to parse the DBBC3 multicast in a way similar to the RDBE.

To what extent is DBBC3 supported in DRUDG? If non/limited; do we know what is lacking?
Currently only handles git repos.
Remove for that case?
If the FS is in /usr2/fs-git, the wrong link is set for /usr2/fs. Maybe the solution is to use the last directory field from pwd BEFORE the script cd's to /usr2. Maybe:
DIRECTORY := (
And then use $DIRECTORY everywhere in place fs-$FS_VERSION
This should handle git repos (whether name fs-git or not) or archive versions that would the version explicit in the directory name, e.g. fs-10.0.0.
Maybe POSIX IPC has something. If so maybe the libraries could rewritten using that. Maybe we should get off system V anyway. Maybe POSIX would give us longer message queues (or is having these smallish better anyway).
