From efe4be12490ab684786c48135731c4d2648bbecc Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Thu, 1 Mar 2012 22:40:51 +0100 Subject: bundle: keep around names passed to add_pending_object() The 'name' field passed to add_pending_object() is used to later deduplicate in object_array_remove_duplicates(). git-bundle had a bug in this area since 18449ab (git-bundle: avoid packing objects which are in the prerequisites, 2007-03-08): it passed the name of each boundary object in a static buffer. In other words, all that object_array_remove_duplicates() saw was the name of the *last* added boundary object. The recent switch to a strbuf in bc2fed4 (bundle: use a strbuf to scan the log for boundary commits, 2012-02-22) made this slightly worse: we now free the buffer at the end, so it is not even guaranteed that it still points into addressable memory by the time object_array_remove_ duplicates looks at it. On the plus side however, it was now detectable by valgrind. The fix is easy: pass a copy of the string to add_pending_object.
