From fff0d0abdde6729606824688c2acac72db643e65 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Thu, 15 Apr 2010 02:25:38 -0500 Subject: [PATCH 1/3] Document new "already-merged" rule for branch -d MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit v1.7.0-rc0~18^2 (branch -d: base the "already-merged" safety on the branch it merges with, 2009-12-29) taught ‘git branch’ a new heuristic for when it is safe to delete a branch without forcing the issue. It is safe to delete a branch "topic" without second thought if: - the branch "topic" is set up to pull from a (remote-tracking, usually) branch and is fully merged in that "upstream" branch, or - there is no branch.topic.merge configuration and branch "topic" is fully merged in the current HEAD. Update the man page to acknowledge the new rules.

From 21798708031ed808cb77232e771e20d3146cf9c8 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Thu, 15 Apr 2010 14:59:37 +0200 Subject: [PATCH 2/3] combined diff: correctly handle truncated file MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Consider an evil merge of two commits A and B, both of which have a file 'foo', but the merge result does not have that file. The combined-diff code learned in 4462731 (combine-diff: do not punt on removed or added files., 2006-02-06) to concisely show only the removal, since that is the evil part and the previous contents are presumably uninteresting. However, to diagnose an empty merge result, it overloaded the variable that holds the file's length. This means that the check also triggers for truncated files. Consequently, such files were not shown in the diff at all despite the merge being clearly evil. Fix this by adding a new variable that distinguishes whether the file was deleted (which is the case 4462731 handled) or truncated. In the truncated case, we show the full combined diff again, which is rather spammy but at least does not hide the evilness.
