In preparation for having the "log" family of functions make wider use of release_revisions() let's have them call it just before exiting. This changes the "log", "whatchanged", "show", "format-patch", etc. commands, all of which live in this file. The release_revisions() API still only frees the "pending" member, but will learn to more members of "struct rev_info" in subsequent commits. In the case of "format-patch" revert the addition of UNLEAK() in dee839a2633 (format-patch: mark rev_info with UNLEAK, 2021-12-16), and which will cause several tests that previously passed under "TEST_PASSES_SANITIZE_LEAK=true" to start failing. In subsequent commits we'll now be able to use those tests to check whether that part of the API is really leaking memory, and will fix all of those memory leaks. Removing the UNLEAK() allows us to make incremental progress in that direction. See [1] for further details about this approach. 1. https://lore.kernel.org/git/220218.861r00ib86.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> --- builtin/log.c | 20 ++++++++++++-------- t/t4126-apply-empty.sh | 2 -- 2 files changed, 12 insertions(+), 10 deletions(-)
