From 91f8f7e46fd86f2d20e93e00af451bf75febfe18 Mon Sep 17 00:00:00 2001 From: René Scharfe Date: Sat, 30 Apr 2022 12:32:44 +0200 Subject: 2.36 format-patch regression fix MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit e900d494dc (diff: add an API for deferred freeing, 2021-02-11) added a way to allow reusing diffopts: the no_free bit. 244c27242f (diff.[ch]: have diff_free() call clear_pathspec(opts.pathspec), 2022-02-16) made that mechanism mandatory. git format-patch only sets no_free when --output is given, causing it to forget pathspecs after the first commit. Set no_free unconditionally instead. The existing test was unable to detect this breakage because it checks stderr for the absence of a certain string, but format-patch writes to stdout. Also the test was not checking the case of one commit modifying multiple files and a pathspec limiting the diff. Replace it with a more thorough one.
