From 64a99eb4760de2ce2f0c04e146c0a55c34f50f20 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Thu, 8 Aug 2013 18:05:38 +0700 Subject: gc: reject if another gc is running, unless --force is given MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This may happen when `git gc --auto` is run automatically, then the user, to avoid wait time, switches to a new terminal, keeps working and `git gc --auto` is started again because the first gc instance has not clean up the repository. This patch tries to avoid multiple gc running, especially in --auto mode. In the worst case, gc may be delayed 12 hours if a daemon reuses the pid stored in gc.pid. kill(pid, 0) support is added to MinGW port so it should work on Windows too.
