Subversion - changing way of handling hooks

  • 772

My hosting provider had enabled Trusted Path Execution (Grsec), so all my subversion hooks (for example post-commit) stopped working. Any attempt to commit something ends with warning:

post-commit hook failed (exit code 255) with no output.

I checked, that scripts can be run manually using following syntax:

bash post-commit [PATH] [REV]

but not by:

./post-commit [PATH] [REV]

I think Subversion uses the last one, which cause the problem. So is it possible to change the way which subversion handle hooks?

svn grsec

    Hook execution method is hard-coded in Subversion and you have to patch the source and re-build it, if you want to change that. The relevant code may be found in subversion/libsvn_repos/repos.{c,h} in the source distribution.

    By the way, hooks are currently executed by their full path (as in /path/to/your/repo/hooks/post-commit) and not with cd /path/to/your/repo && ./post-commit.
