From 9116de5957423d553fce5857a835284a0527d037 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Gr=C3=A9goire=20Barbier?= Date: Sat, 19 Jan 2008 16:22:47 +0100 Subject: [PATCH] http-push: fix webdav lock leak. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Releasing webdav lock even if push fails because of bad (or no) reference on command line. To reproduce the issue that this patch fixes, prepare a test repository availlable over http+webdav, say at http://myhost/myrepo.git/ Then: $ git clone http://myhost/myrepo.git/ $ cd myrepo $ git push http Fetching remote heads... refs/ refs/heads/ refs/tags/ No refs in common and none specified; doing nothing. $ git push http Fetching remote heads... refs/ refs/heads/ refs/tags/ No refs in common and none specified; doing nothing. $ Finally, you look at the web server logs, and will find one LOCK query and no UNLOCK query, of course the second one will be in 423 return code instead of 200: 1.2.3.4 - gb [19/Jan/2008:14:24:56 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 200 465 (...) 1.2.3.4 - gb [19/Jan/2008:14:25:10 +0100] "LOCK /myrepo.git/info/refs HTTP/1.1" 423 363 With this patch, there would have be two UNLOCKs in addition of the LOCKs From the user's point of view: - If you realize that you should have typed e.g. "git push http master" instead of "git push http", you will have to wait for 10 minutes for the lock to expire by its own. - Furthermore, if somebody else is dumb enough to type "git push http" while you need to push "master" branch, then you'll need too to wait for 10 minutes too.
