From: Johannes Schindelin Date: Fri, 15 May 2009 18:52:47 +0000 (+0200) Subject: Cope better with a _lot_ of packs X-Git-Tag: v1.6.3.2~28 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=fd73ccf27956f24dc0db9acd4ff7d9dcd5e41bfb;p=git.git Cope better with a _lot_ of packs You might end up with a situation where you have tons of pack files, e.g. when using hg2git. In this situation, all kinds of operations may end up with a "too many files open" error. Let's recover gracefully from that. Signed-off-by: Johannes Schindelin Looks-right-to-me-by: Shawn O.
