From 295dd2ad201c0ebb281563750a13d904bd466e01 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Fri, 9 Nov 2007 06:06:10 -0500 Subject: [PATCH] Fix memory leak in traverse_commit_list If we were listing objects too then the objects were buffered in an array only reachable from a stack allocated structure. When this function returns that array would be leaked as nobody would have a reference to it anymore. Historically this hasn't been a problem as the primary user of traverse_commit_list() (the noble git-rev-list) would terminate as soon as the function was finished, thus allowing the operating system to cleanup memory. However we have been leaking this data in git-pack-objects ever since that program learned how to run the revision listing internally, rather than relying on reading object names from git-rev-list. To better facilitate reuse of traverse_commit_list during other builtin tools (such as git-fetch) we shouldn't leak temporary memory like this and instead we need to clean up properly after ourselves.
