From: Eric Wong Date: Wed, 10 Jan 2007 09:22:38 +0000 (-0800) Subject: git-svn: cleanup: put SVN workarounds into their own namespace X-Git-Tag: v1.5.1-rc1~255 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d81bf827192f0af6b1cca64d2cdbaac9b5ca2020;p=git.git git-svn: cleanup: put SVN workarounds into their own namespace Force some svn_ra functions to use a temporary pool via wrapper This cleans up the code a bit by removing explicit instances of pool allocation and deallocation and providing wrapper functions that make use of temporary pools. I've also added an explicit pool usage when creating the commit editor for commit-diff where get_commit_editor can be called multiple times with the same pool previously.
