Subject: bug report: mutual recursion in the git-subtree shell script
Date: Sat, 13 Mar 2021 08:06:18 -0800 [thread overview]
Message-ID: <CAN7rbOve-EFOGPjr1wrD77r-3RQ+3+qso82_oV5Qud-skobL7w@mail.gmail.com> (raw)
[ resending bug report from git-users since there weren't any responses ]
So I'm trying to split out a directory from postgres source code
(which has 52k commits). I was able to split a directory into a
separate subtree (with 1685 commits). All good so far.
Now I do a pull from upstream and want to push the directory to my
subtree. The command fails with:
$ git subtree push --prefix=src/interfaces/libpq libpq master
/usr/lib/git-core/git-subtree: 647: Maximum function recursion depth
(1000) reached
As far as I can see, it seems to be a mutual recursion between
process_split_commit() and check_parents()
If this diagnosis is correct, are there any known workarounds? I've
tried increasing ulimit -s and FUNCNEST=10000, but it didn't fix the
problem.
Can this flow be coded without using recursion? Are there
implementations of git-subtree in another language which doesn't have
this problem?
