Call diff_free() on the "pruning" member of "struct rev_info". Doing so makes several tests pass under SANITIZE=leak. This was also the last missing piece that allows us to remove the UNLEAK() in "cmd_diff" and "cmd_diff_index", which allows us to use those commands as a canary for general leaks in the revisions API. See [1] for further rationale, and 886e1084d78 (builtin/: add UNLEAKs, 2017-10-01) for the commit that added the UNLEAK() there. 1. https://lore.kernel.org/git/220218.861r00ib86.gmgdl@evledraar.gmail.com/ (local) Signed-off-by: Ævar Arnfjörð Bjarmason <redacted> --- builtin/diff-index.c | 1 - builtin/diff.c | 1 - revision.c | 1 + t/t1001-read-tree-m-2way.sh | 1 + t/t1002-read-tree-m-u-2way.sh | 1 + t/t2200-add-update.sh | 1 + t/t4039-diff-assume-unchanged.sh | 1 + t/t4206-log-follow-harder-copies.sh | 2 ++ t/t6131-pathspec-icase.sh | 2 ++ 9 files changed, 9 insertions(+), 2 deletions(-)
