From 7a98d9ab00dc0a238b624b20c3884b50fe504e2b Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Wed, 13 Apr 2022 22:01:47 +0200 Subject: [PATCH] revisions API: have release_revisions() release "cmdline" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Extend the the release_revisions() function so that it frees the "cmdline" in the "struct rev_info". This in combination with a preceding change to free "commits" and "mailmap" means that we can whitelist another test under "TEST_PASSES_SANITIZE_LEAK=true". There was a proposal in [1] to do away with xstrdup()-ing this add_rev_cmdline(), perhaps that would be worthwhile, but for now let's just free() it. We could also make that a "char *" in "struct rev_cmdline_entry" itself, but since we own it let's expose it as a constant to outside callers. I proposed that in [2] but have since changed my mind. See 14d30cdfc04 (ref-filter: fix memory leak in `free_array_item()`, 2019-07-10), c514c62a4fd (checkout: fix leak of non-existent branch names, 2020-08-14) and other log history hits for "free((char *)" for prior art. This includes the tests we had false-positive passes on before my 6798b08e848 (perl Git.pm: don't ignore signalled failure in _cmd_close(), 2022-02-01), now they pass for real. Since there are 66 tests matching t/t[0-9]*git-svn*.sh it's easier to list those that don't pass than to touch most of those 66. So let's introduce a "TEST_FAILS_SANITIZE_LEAK=true", which if set in the tests won't cause lib-git-svn.sh to set "TEST_PASSES_SANITIZE_LEAK=true. This change also marks all the tests that we removed "TEST_FAILS_SANITIZE_LEAK=true" from in an earlier commit due to removing the UNLEAK() from cmd_format_patch(), we can now assert that its API use doesn't leak any "struct rev_info" memory. This change also made commit "t5503-tagfollow.sh" pass on current master, but that would regress when combined with ps/fetch-atomic-fixup's de004e848a9 (t5503: simplify setup of test which exercises failure of backfill, 2022-03-03) (through no fault of that topic, that change started using "git clone" in the test, which has an outstanding leak). Let's leave that test out for now to avoid in-flight semantic conflicts. 1. https://lore.kernel.org/git/YUj%2FgFRh6pwrZalY@carlos-mbp.lan/ 2. https://lore.kernel.org/git/87o88obkb1.fsf@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- revision.c | 10 ++++++++++ t/lib-git-svn.sh | 4 ++++ t/t0062-revision-walking.sh | 1 + t/t0101-at-syntax.sh | 2 ++ t/t1060-object-corruption.sh | 1 + t/t3303-notes-subtrees.sh | 1 + t/t3305-notes-fanout.sh | 1 + t/t3408-rebase-multi-line.sh | 1 + t/t4027-diff-submodule.sh | 1 + t/t4128-apply-root.sh | 1 + t/t4212-log-corrupt.sh | 1 + t/t5515-fetch-merge-logic.sh | 1 + t/t5518-fetch-exit-status.sh | 1 + t/t6002-rev-list-bisect.sh | 1 + t/t6003-rev-list-topo-order.sh | 1 + t/t6005-rev-list-count.sh | 1 + t/t6018-rev-list-glob.sh | 1 + t/t6100-rev-list-in-order.sh | 1 + t/t9100-git-svn-basic.sh | 1 + t/t9101-git-svn-props.sh | 2 ++ t/t9104-git-svn-follow-parent.sh | 2 ++ t/t9106-git-svn-commit-diff-clobber.sh | 2 ++ t/t9115-git-svn-dcommit-funky-renames.sh | 1 + t/t9116-git-svn-log.sh | 2 ++ t/t9122-git-svn-author.sh | 2 ++ t/t9127-git-svn-partial-rebuild.sh | 2 ++ t/t9129-git-svn-i18n-commitencoding.sh | 1 + t/t9132-git-svn-broken-symlink.sh | 1 + t/t9139-git-svn-non-utf8-commitencoding.sh | 1 + t/t9146-git-svn-empty-dirs.sh | 2 ++ t/t9148-git-svn-propset.sh | 1 + t/t9151-svn-mergeinfo.sh | 1 + t/t9160-git-svn-preserve-empty-dirs.sh | 1 + t/t9162-git-svn-dcommit-interactive.sh | 2 ++ t/t9164-git-svn-dcommit-concurrent.sh | 2 ++ t/t9501-gitweb-standalone-http-status.sh | 1 + 36 files changed, 58 insertions(+) diff --git a/revision.c b/revision.c index 622f0faecc..de4076e77d 100644 --- a/revision.c +++ b/revision.c @@ -2926,6 +2926,15 @@ int setup_revisions(int argc, const char **argv, struct rev_info *revs, struct s return left; } +static void release_revisions_cmdline(struct rev_cmdline_info *cmdline) +{ + unsigned int i; + + for (i = 0; i < cmdline->nr; i++) + free((char *)cmdline->rev[i].name); + free(cmdline->rev); +} + static void release_revisions_mailmap(struct string_list *mailmap) { if (!mailmap) @@ -2938,6 +2947,7 @@ void release_revisions(struct rev_info *revs) { free_commit_list(revs->commits); object_array_clear(&revs->pending); + release_revisions_cmdline(&revs->cmdline); release_revisions_mailmap(revs->mailmap); } diff --git a/t/lib-git-svn.sh b/t/lib-git-svn.sh index 2fde2353fd..ea28971e8e 100644 --- a/t/lib-git-svn.sh +++ b/t/lib-git-svn.sh @@ -1,3 +1,7 @@ +if test -z "$TEST_FAILS_SANITIZE_LEAK" +then + TEST_PASSES_SANITIZE_LEAK=true +fi . ./test-lib.sh if test -n "$NO_SVN_TESTS" diff --git a/t/t0062-revision-walking.sh b/t/t0062-revision-walking.sh index 8e215867b8..b9480c8178 100755 --- a/t/t0062-revision-walking.sh +++ b/t/t0062-revision-walking.sh @@ -5,6 +5,7 @@ test_description='Test revision walking api' +TEST_PASSES_SANITIZE_LEAK=true . ./test-lib.sh cat >run_twice_expected <<-EOF diff --git a/t/t0101-at-syntax.sh b/t/t0101-at-syntax.sh index a1998b558f..878aadd64c 100755 --- a/t/t0101-at-syntax.sh +++ b/t/t0101-at-syntax.sh @@ -1,6 +1,8 @@ #!/bin/sh test_description='various @{whatever} syntax tests' + +TEST_PASSES_SANITIZE_LEAK=true . ./test-lib.sh test_expect_success 'setup' ' diff --git a/t/t1060-object-corruption.sh b/t/t1060-object-corruption.sh index bc89371f53..e8a58b1589 100755 --- a/t/t1060-object-corruption.sh +++ b/t/t1060-object-corruption.sh @@ -1,6 +1,7 @@ #!/bin/sh test_description='see how we handle various forms of corruption' + . ./test-lib.sh # convert "1234abcd" to ".git/objects/12/34abcd" diff --git a/t/t3303-notes-subtrees.sh b/t/t3303-notes-subtrees.sh index eac193757b..bc9b791d1b 100755 --- a/t/t3303-notes-subtrees.sh +++ b/t/t3303-notes-subtrees.sh @@ -5,6 +5,7 @@ test_description='Test commit notes organized in subtrees' GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME +TEST_PASSES_SANITIZE_LEAK=true . ./test-lib.sh number_of_commits=100 diff --git a/t/t3305-notes-fanout.sh b/t/t3305-notes-fanout.sh index 9976d787f4..64a9915761 100755 --- a/t/t3305-notes-fanout.sh +++ b/t/t3305-notes-fanout.sh @@ -2,6 +2,7 @@ test_description='Test that adding/removing many notes triggers automatic fanout restructuring' +TEST_PASSES_SANITIZE_LEAK=true . ./test-lib.sh path_has_fanout() { diff --git a/t/t3408-rebase-multi-line.sh b/t/t3408-rebase-multi-line.sh index cde3562e3a..7b4607d72f 100755 --- a/t/t3408-rebase-multi-line.sh +++ b/t/t3408-rebase-multi-line.sh @@ -5,6 +5,7 @@ test_description='rebasing a commit with multi-line first paragraph.'
