Subject: Possibly solved invalid free() in git-remote-http from Git 1.7.2.1
Date: Mon, 1 Aug 2011 17:22:47 +0200 [thread overview]
Message-ID: <CACBZZX7s+NeH2jLC9Ym65_rMQkgVmfbCAkqZbBFhTiY9U8uP2A@mail.gmail.com> (raw)
In case anyone would like to look into this I had this undiagnosed
free() error from git-remote-http in git version 1.7.2.1:
error: Couldn't create temporary file
/tmp/clone/main.git/.git/objects/e3/2a06e85053d958f78a20f37c9604e40b8282ad.temp:

It happened when I rm -rf'd the /tmp/clone directory that
git-remote-http was working on. It's possibly fixed in later versions
of git, I didn't check.
Just posting it here in case someone has time to write a test for this
/ track it down. I don't at the moment.q
