Subject: kgb-bot hangs forever at test suite

package: kgb-bot
version: 1.33-2
x-debbugs-cc: reproducible-builds@lists.alioth.debian.org

Hi,

while rebuilding kgb-bot for reproducibility we noticed the testsuite hanging 
forever as can be seen in 
https://jenkins.debian.net/view/reproducible/job/reproducible_builder_zeta/2745/console 
or below.

The rebuild was done using pbuilder from wheezy, building in a sid chroot 
without networking set up...

If you need any other information or if you have things to test, I'd be glad 
to help debugging.

From the build log:

Thanks for maintaining kgb-bot and the bots - that's a super useful service to 
the community!

Thanks for the report. I was able to reproduce the problem by looping 
over building the package (in a wheezy pbuilder chroot) until the test 
suite hung.

In my test it hung after another test, but also in the place when the 
test tries to stop the running test bot instance. The test script was 
busy-looping checking for the existence of the lock file.

It seems that sometimes the test bot fails to stop (or to clean up), 
causing the test to hang.

I'll investigate further these days.

:)  We have plans to improve the service even further:

Description: 
 kgb-bot    - IRC collaboration bot
 kgb-client - client for KGB (IRC collaboration bot)
Changes:
 kgb-bot (1.34-1) unstable; urgency=medium
 .
   [ gregor herrmann ]
   * kgb-client.conf(5): change example shortening service from Metamark to
     TinyURL, following the example of WWW::Shorten. Metamark is not
     accepting new URLs anymore.
 .
   [ Damyan Ivanov ]
   * also mention cgit in the web-link description
   * add a new script, kgb-ci-report. used to notify about CI failures
   * bump years of copyright
 .
   [ Pierre Schweitzer ]
   * kgb-client: use login name when the full user name is not available
     Closes: #772747
   * Remove ${{project/}} token from the example multi-line message
     configuration (already removed from the single-line configuration)
     Closes: #772749
   * Fix multiline message template
     Closes: #772750
 .
   [ Damyan Ivanov ]
   * TestBot:
     - when waiting for the PID file to appear, also see if it has any content
     - close the PID file after reading it
   * kgb-bot:
     - add the PID to the "Listening on ..." line in the log
     - rewrite the PID management code using OO interface of Proc::PID::File.
       This fixes a rather nasty hardly-reproducible bug causing the PID file
       to be re-created after being removed, which may fool the tests and make
       them hang.
       Closes: #782079
   * kgb-client: add libwww-perl to Recommends, needed by kgb-ci-report
 .
   [ gregor herrmann ]
   * Update (build) dependencies.
     - build-depend on libmodule-build-perl only
       Closes: #834597
     - move libmodule-build-perl to Build-Depends.
     - remove unneeded version from kgb-client dependency
     - add build dependency on libdbd-pg-perl
   * Update Vcs-* headers-.
   * Declare compliance with Debian Policy 3.9.8.
   * Bump debhelper compatibility level to 9.
   * Build.PL:
     - install new kgb-ci-report script
     - add DBD::Pg as requirement in Build.PL
   * debian/*: Switch some URLs to HTTPS. Thanks to duck.
   * Fix some typos in the POD. Thanks to lintian.
   * Drop fix-username-in-tests.patch; applied.
   * Update years of packaging copyright.
 .
   [ Martín Ferrari ]
   * App::KGB::Client::ServerRef:
     - More consistent verbose reporting of server communication.
     - Add --dry-run option for debugging.
     - Bug fix: use correct method when sending a commit info with
       default protocol.
   * App::KGB::Client: format_message: Don't lose data.
     When the commit object does not have all the info, it still overwrites
     data coming from the extra arguments. It meant SVN commits were lacking
     branch and module information completely.
 .
   [ gregor herrmann ]
   * Fix t/52-client-git.t to work with newer git versions as well.
     Since 2.9.0, git allows merging branches without a common ancestors only
     when "--allow-unrelated-histories" is passed. This has lead to test
     failures.
     Pass the parameter conditionally.
