bug#29546: Intermittent test failures in 'git'

[Mark H Weaver]

On Hydra, the following intermittent test failure in 'git' has occurred
twice in the last two days, and twice about a month ago:

--8<---------------cut here---------------start------------->8---
not ok 3 - git svn branch tests
#	
#		test_must_fail git svn branch a &&
#		git svn branch --parents a &&
#		test_must_fail git svn branch -t tag1 &&
#		git svn branch --parents -t tag1 &&
#		test_must_fail git svn branch --tag tag2 &&
#		git svn branch --parents --tag tag2 &&
#		test_must_fail git svn tag tag3 &&
#		git svn tag --parents tag3
#	
# failed 1 among 3 test(s)
1..3
make[2]: *** [Makefile:49: t9167-git-svn-cmd-branch-subproject.sh] Error 1
--8<---------------cut here---------------end--------------->8---

The problem is not architecture specific.  It has occurred at least once
on all three hydra-supported-systems (x86_64, i686, and armhf).  The
collateral damage includes several hundred dependency failures.

The following error also happened once on x86_64 about a month ago:

--8<---------------cut here---------------start------------->8---
not ok 3 - git svn branch tests
#	
#		git svn branch a &&
#		base=$(git rev-parse HEAD:) &&
#		test $base = $(git rev-parse remotes/origin/a:) &&
#		git svn branch -m "created branch b blah" b &&
#		test $base = $(git rev-parse remotes/origin/b:) &&
#		test_must_fail git branch -m "no branchname" &&
#		git svn branch -n c &&
#		test_must_fail git rev-parse remotes/origin/c &&
#		test_must_fail git svn branch a &&
#		git svn branch -t tag1 &&
#		test $base = $(git rev-parse remotes/origin/tags/tag1:) &&
#		git svn branch --tag tag2 &&
#		test $base = $(git rev-parse remotes/origin/tags/tag2:) &&
#		git svn tag tag3 &&
#		test $base = $(git rev-parse remotes/origin/tags/tag3:) &&

#		git svn tag -n tag5 &&
#		test_must_fail git rev-parse remotes/origin/tags/tag5 &&
#		test_must_fail git svn tag tag1
#

Hi Mark,

This was discussed in <https://bugs.gnu.org/29512>, which led to commit
c03ba83c17c91e34e811a909fae0f63aab701ff9 to run tests sequentially.

Currently that seems to work well:

  https://hydra.gnu.org/job/gnu/master/git-2.15.1.x86_64-linux
  https://hydra.gnu.org/job/gnu/master/git-2.15.1.i686-linux

The ARM build is still running though:

  https://hydra.gnu.org/job/gnu/master/git-2.15.1.armhf-linux

Let’s see if the problem shows up again.

Bad news, it failed (see
<https://hydra.gnu.org/build/2367151/nixlog/2/tail-reload>):

I tried building it for i686 on my laptop and it failed similarly.

This bug report seems to be relevant, and it suggests bugs in the Perl
bindings of Subversion:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=871562

For now I’ve disabled three of the git-svn tests that were reported to
fail intermittently in commit c7699ebeb4233d81f294ff7e8b8eb3676119ae4a,
so that we can hopefully build Git more reliably.

Hi,

I'm closing this old report, as our git packages seems to build reliably
now.
