Diagnosis

Perform the following steps with the user that will run Stash:

  1. git --version
cd $STASH_HOME/tmp
git init git-perl-test
cd git-perl-test

  2. Create a new file .git/hooks/pre-commit with the following content:

    #!/usr/bin/env bash
perl -v > .git/perl-version

  3. Make sure the file is executable and create a commit to test that the Git hooks work and the Perl version is compatible:

    chmod u+x .git/hooks/pre-commit
echo test > temp
git add -A --
git commit -m "Initial"
cat .git/perl-version

For reference, an output similar to the following is expected:

kraken:~ mheemskerk$ git --version
git version 1.7.10.2 (Apple Git-33)
kraken:tmp mheemskerk$ cd $STASH_HOME/tmp
kraken:tmp mheemskerk$ git init git-perl-test
Initialized empty Git repository in /Users/mheemskerk/tmp/git-perl-test/.git/
kraken:tmp mheemskerk$ cd git-perl-test
kraken:git-perl-test mheemskerk$ emacs .git/hooks/pre-commit
kraken:git-perl-test mheemskerk$ chmod u+x .git/hooks/pre-commit
kraken:git-perl-test mheemskerk$ echo test > temp
kraken:git-perl-test mheemskerk$ git add -A --
kraken:git-perl-test mheemskerk$ git commit -m "Initial"
[master (root-commit) 5b50935] Initial
 1 file changed, 1 insertion(+)
 create mode 100644 temp
kraken:git-perl-test mheemskerk$ cat .git/perl-version

This is perl 5, version 12, subversion 4 (v5.12.4) built for darwin-thread-multi-2level
(with 2 registered patches, see perl -V for more detail)

Cause

There are two possible causes for this behavior:

  • $STASH_HOME is mounted over NFS with the "noexec" option and thus no hooks can be executed.
  • Perl has been upgraded after the Git installation.

Resolution

According to the causes, there are two solutions:

  • Remove the NFS "noexec" option and remount.
  • Recompile Git with the newer version of Perl.
