Error Code 431

Error Code 431

[Prashanth Guduru]

Hi,

I have gnats-4.0 installed and have gnatsd running on
a machine. I have gnatsweb-4.0 setup on my webserver
machine and have setup the gnatsweb.html
appropriately.
I now have created 4 databases and whenever anyone
tries to create a PR the gnats.lock file in the
$GNATSROOT/database/gnats-adm directory doesnt get
deleted. After the PR is submitted, the gnatsweb page
says "Error : unparseable reply from server". When
queried i can see the PR created. I have also tried
creating a PR using send-pr from  a different machine
than the one that runs gnatsd and has databases on it.
I have set the GNATSDB env variable for this to work.
send-pr creates a new PR but i have also observed the
gnats.lock file is created and then deleted by the
send-pr. I have been having difficulties figuring out
why gnatsweb's create PR request is not being handled
properly by the gnatsd. Is there a way i can view the
logs/output of gnatsd. Have anybody seen this kinda
behaviour before. THanks in advance.

Regards,
Prashanth

Sorry to hear you are having difficulties.

GNATS logging is still an undocumented mess. However, the first thing I 
would advise you to do is to turn on debug output in Gnatsweb. Simply 
add the string "?debug=all" to the URL you use to access Gnatsweb. Thus, 
the access URL should read something similar to this:

http://www.example.com/cgi-bin/gnatsweb.pl?debug=all

Hi Prashanth,

I have had a look into the gnatsd logging functionality to see if it
might help you with this problem.  Sometimes gnatsd will log error
messages to the system log, so it might be worthwhile looking there to
see if there are any messages that appear when the problem occurs.
(I think the system log is /var/log/messages on a default Red Hat
GNU/Linux installation.)

The gnatsd code has functionality for logging "debugging" information,
but there is no interface for enabling this.  To enable it you would
need to make a small change to the source code, rebuild and reinstall
GNATS.  A patch file with the the required change is at the end of
this message.  The information logged when a PR is successfully
created is not very extensive, it looks like this:

Sep 14 13:22:08 olga gnatsd[1936]: gnatsd: responsible person is: andrewg 
Sep 14 13:22:08 olga gnatsd[1936]: gnatsd: PR written out: /usr/local/com/gnatsdb/hammer/2

It is difficult to say if enabling debug logging would help you find
the cause of the problem you are seeing.  I guess it might be worth a
try if you exhaust other approaches.

Hi Yngve,

THanks for your prompt response. I have actually done
that, i mean having "?debug=all" appended to the url. 
I have 2 different databases, the first one i created
was "test", it doesnt have any categories except for
the default ones.
I can create a PR using GNATSWEB in the test database
with no problem of the gnats.lock file being left
undeleted. So what i did was i did ?debug=all for both
the cases, i mean for the test database and for the
other database.Heres what i observed.

server_reply: 210 PR added. 



THis is the last client command that is run in both
the cases. For the test database i can see the
server_reply: 210 PR added and in case of the other
database when PR is created the "server_reply:" is
empty and thats when i get "Error: Unparseable reply
from server" and that follows the "Problem Report
Sent. THank you for your report...........". I have
closely observed the both databases, except for the
categories there is no difference in them atall. I
dont quite understand why isnt there a 210 PR added
response from server and why is'nt the gnats.lock file
getting deleted. Any comments.

Regards,
Prashanht

210 PR added.

This is really confusing. If there is a problem with
gnatsweb.pl and if its sending bogus to gnatsd that it
cant handle, then i dont understand why there is no
error with the test database. From this little test
that Mel suggested i feel gnatsd shuld be ok. Any
ideas?

Thanks,
Prashanth

Thanks for posting that output.

I'm not sure I have the details of the problem right, so I will repeat
the key things:

- When someone submits a PR via Gnatsweb the gnats.lock file in
  $GNATSROOT/database/gnats-adm is created but is not deleted.  The PR
  is created but Gnatsweb reports "Error : unparseable reply from
  server".

- This happens with all four "real" databases.

- You can create a PR in the "real" databases by using send-pr and by
  running gnatsd from the command line and entering the PR manually
  (as suggested by Mel).  In this case no error is generated and the
  gnats.lock file is deleted as expected.

- When you create a test database that does not have any categories
  except for the default ones, you can submit a PR via Gnatsweb and
  the gnats.lock file is deleted as expected.

Is the above correct?  Have I missed anything you think is important?

From this it appears that something about your "real" configurations
is triggering a problem in the interaction between Gnatsweb and
gnatsd.  That would explain there being no error when submitting a PR
to the test database via Gnatsweb.  In other words, it is not simply a
problem with gnatsweb.pl sending the wrong thing.  The test with
running gnatsd from the command line (as Mel suggested) indicates that
gantsd can handle PR submissions for the "real" databases in some
circumstances, but apparently something is different in what Gnatsweb
does.

Some things you could try:

- Adding to the test configuration to make it like one of the "real"
  databases until the problem occurs.  I understand this is a tedious
  process, but it might be effective.

- Looking for gnatd core files.  If gnatsd is crashing, as Yngve
  suggested, then it may be leaving a core file, as Mel indicated.  I
  do not know where the core file would be created, I guess the
  directory where the gnatsd executable lives, that is
  /usr/local/libexec/gnats be default.  If there is no core file there
  you could try triggering the problem then searching the complete
  file system for core files generated in the last 10 minutes:

  find / -mmin -10 -name core -print

  The stack trace from a core file would be very useful in finding the
  cause of the problem.

Re: Error Code 431

[Prashanth Guduru]

Hi Andrew,

Yes, youve got everything right. I dont think at this
moment i have any new observations yet. But i did look
for the messages file for any information about
gnatsd. All i see is the inetd started gnatsd and
thats about it. I dont see any indications of a crash
or core dump and cant find any core files on the
system. I still have to make the change in the code
and rebuild gnats for the debug information. Will post
the output if i find thats useful. Thanks for your
time and help. Meanwhile please let me know if you
think of something else.

Bests,
Prashanth

Re: Error Code 431

[Prashanth Guduru]

Hi all,

Its been a long time that i havent written back as i
said. I have done some testing and finally found that
there is something wrong in the dbconfig. I had edited
the dbconfig to delete unnecassary fields and i was 
careful in doing so. Whenever i deleted an entry in
the
sql structure or the others i made sure i also deleted
the qualifying string, like the %s. So i was using
this dbconfig as the default dbconfig, so that all
the databases used it when they were created. Hence
was seeing the same problem in all the databases. I
finally grabbed the original dbconfig that came with
the distribution and started using it. I dont seem
to have the same problem again. Thanks to everyone who
promptly replied to my messages.
