From cc5fa2fdafa186d6e1e310828b22d0028e1fb51b Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Fri, 17 Dec 2010 20:26:47 +0700 Subject: [PATCH] Make rev-list --objects work together with pathspecs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When traversing commits, the selection of commits would heed the list of pathspecs passed, but subsequent walking of the trees of those commits would not. This resulted in 'rev-list --objects HEAD -- ' displaying objects at unwanted paths. Have process_tree() call tree_entry_interesting() to determine which paths are interesting and should be walked. Naturally, this change can provide a large speedup when paths are specified together with --objects, since many tree entries are now correctly ignored. Interestingly, though, this change also gives me a small (~1%) but repeatable speedup even when no paths are specified with --objects.
