From: Johannes Schindelin <redacted> I noticed recently that the leak-checking jobs still take a lot of time, and upon analysis, the git-svn tests contribute significantly to this. Analyzing a recent CI run, I saw that the Git test suite contains 1,017 tests, running for approximately 5¼ hours total. Of these, 65 git-svn-related tests (~6% of test count) took 42.24 minutes combined, accounting for ~13.% of the total runtime. This implies that the git-svn tests are roughly twice as expernsive compared to the other tests.
Looking at the CI logs for this PR the p4 and cvs tests account for another 24 minutes of test time and I suspect they also offer little in the way of extra coverage. Unfortunately there is no equivalent of NO_SVN_TESTS to disable them - I wonder if building with NO_PYTHON and NO_PERL would make sense for the leak test job? Either way I like the direction of this patch Thanks Phillip

However, testing git-svn in the leak-checking jobs provides minimal value: git-svn is implemented as a Perl script, and leak checking only handles C code. While git-svn does call into Git's built-in commands that are implemented in C, these are standard Git operations that are already thoroughly exercised elsewhere in the test suite. Therefore, running the git-svn tests in the leak-checking jobs only adds to the overall run time with little value in return. Given that the leak-checking jobs are particularly time-intensive and these 42+ minutes of SVN tests per job provide no additional leak detection value, skip them in the *-leaks jobs to reduce CI runtime. Assisted-by: Claude Sonnet 4.5 Signed-off-by: Johannes Schindelin <redacted> --- ci(*-leaks): skip the git-svn tests to save time I leaned heavily on AI to implement this patch, in particular when analyzing the logs. That's why I added that trailer talking about Claude Sonnet. If this is undesirable, please let me know.
