I have applied this to maint-2.39 and then merged them up to the
maintenance tracks. The results will be pushed out to the "split
out" repository at
https://github.com/gitster/git/
as these branches:
js/fix-clone-w-hooks-2.39
js/fix-clone-w-hooks-2.40

js/fix-clone-w-hooks-2.42
js/fix-clone-w-hooks-2.43
js/fix-clone-w-hooks-2.44
js/fix-clone-w-hooks-2.45
For those who are merging them up at home yourselves, here are the
remerge diff that show the conflict resolution I made.

As it happens, I had already worked on tentative/maint-* branches (that you can see here: https://github.com/dscho/git/branches/active), but had to take a break before finalizing them. The major difference I see is that js/fix-clone-w-hooks-2.41 still declares `do_files_match()` in `setup.h` (even if it is no longer defined or called), and that `hook.c` includes `copy.h` (but that is no longer needed), and that `setup.h` includes `hook.h` (but that's not needed either). While comparing, I noticed that I had missed an extra empty line in my merge conflict resolutions, a `grep` -> `test_grep` conversation and an `UNUSED` attribute for the `ctx` parameter of the `safe_hook_cb()` function. So I am really grateful that you did those integrations independently. You will also note that I tentatively added commits to mark v2.39.5, ..., v2.45.2 ready for tagging, along with release notes, just so we can hit the ground running as soon as reviews settle down.

Oh, I forgot to mention that I also integrated backports of some CI fixes into the `tentative/maint-*` branches, to let the `osx-gcc` job pass again. Ciao, Johannes >
There have been a couple of issues that were reported about v2.45.1, and in addition I have noticed some myself: * a memory leak in the clone protection logic * a missed adjustment in the Makefile that leads to an incorrect templates path in v2.39.4, v2.40.2 and v2.41.1 (but not in v2.42.2, ..., v2.45.1) * an overzealous core.hooksPath check * that Git LFS clone problem where it exits with an error (even if the clone often succeeded...) This patch series is based on maint-2.39 to allow for (relatively) easy follow-up versions v2.39.5, ..., v2.45.2. Changes since v1: * simplified adding the SHA-256s corresponding to Git LFS' hooks * the core.hooksPath test case now verifies that the config setting was configured correctly Johannes Schindelin (8): hook: plug a new memory leak init: use the correct path of the templates directory again Revert "core.hooksPath: add some protection while cloning" tests: verify that `clone -c core.hooksPath=/dev/null` works again hook(clone protections): add escape hatch hooks(clone protections): special-case current Git LFS hooks hooks(clone protections): simplify templates hooks validation Revert "Add a helper function to compare file contents" Documentation/config/safe.txt | 6 ++ Makefile | 2 +- builtin/init-db.c | 7 +++ cache.h | 14 ----- config.c | 13 +---- copy.c | 58 -------------------- hook.c | 100 +++++++++++++++++++++++++++------- hook.h | 10 ++++ setup.c | 1 + t/helper/test-path-utils.c | 10 ---- t/t0060-path-utils.sh | 41 -------------- t/t1350-config-hooks-path.sh | 7 +++ t/t1800-hook.sh | 40 ++++++++++---- t/t5601-clone.sh | 19 +++++++ 14 files changed, 161 insertions(+), 167 deletions(-) base-commit: 47b6d90e91835082010da926f6a844d4441c57a6 Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-1732%2Fdscho%2Fvarious-fixes-for-v2.45.1-and-friends-v2 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-1732/dscho/various-fixes-for-v2.45.1-and-friends-v2 Pull-Request: https://github.com/gitgitgadget/git/pull/1732 Range-diff vs v1: 1: d4a003bf2ce = 1: d4a003bf2ce hook: plug a new memory leak 2: 961dfc35f42 = 2: 961dfc35f42 init: use the correct path of the templates directory again 3: 57db89a1497 = 3: 57db89a1497 Revert "core.hooksPath: add some protection while cloning" 4: 7d5ef6db2a9 ! 4: cd14042b065 tests: verify that `clone -c core.hooksPath=/dev/null` works again @@ t/t1350-config-hooks-path.sh: test_expect_success 'git rev-parse --git-path hook ' +test_expect_success 'core.hooksPath=/dev/null' ' -+ git clone -c core.hooksPath=/dev/null . no-templates ++ git clone -c core.hooksPath=/dev/null . no-templates && ++ value="$(git -C no-templates config --local core.hooksPath)" && ++ # The Bash used by Git for Windows rewrites `/dev/null` to `nul` ++ { test /dev/null = "$value" || test nul = "$value"; } +' + test_done 5: a4f5eeef667 = 5: b841db8392e hook(clone protections): add escape hatch 6: 98465797e72 ! 6: 5e5128bc232 hooks(clone protections): special-case current Git LFS hooks @@ Commit message ## hook.c ## @@ hook.c: static int is_hook_safe_during_clone(const char *name, const char *path, char *s - if (get_sha256_of_file_contents(path, sha256) < 0) - return 0; -+ /* Hard-code known-safe values for Git LFS v3.4.0..v3.5.1 */ -+ if ((!strcmp("pre-push", name) && -+ !strcmp(sha256, "df5417b2daa3aa144c19681d1e997df7ebfe144fb7e3e05138bd80ae998008e4")) || -+ (!strcmp("post-checkout", name) && -+ !strcmp(sha256, "791471b4ff472aab844a4fceaa48bbb0a12193616f971e8e940625498b4938a6")) || -+ (!strcmp("post-commit", name) && -+ !strcmp(sha256, "21e961572bb3f43a5f2fbafc1cc764d86046cc2e5f0bbecebfe9684a0b73b664")) || -+ (!strcmp("post-merge", name) && -+ !strcmp(sha256, "75da0da66a803b4b030ad50801ba57062c6196105eb1d2251590d100edb9390b"))) -+ return 1; -+ if (!safe_hook_sha256s_initialized) { safe_hook_sha256s_initialized = 1; ++ ++ /* Hard-code known-safe values for Git LFS v3.4.0..v3.5.1 */ ++ /* pre-push */ ++ strset_add(&safe_hook_sha256s, "df5417b2daa3aa144c19681d1e997df7ebfe144fb7e3e05138bd80ae998008e4"); ++ /* post-checkout */ ++ strset_add(&safe_hook_sha256s, "791471b4ff472aab844a4fceaa48bbb0a12193616f971e8e940625498b4938a6"); ++ /* post-commit */ ++ strset_add(&safe_hook_sha256s, "21e961572bb3f43a5f2fbafc1cc764d86046cc2e5f0bbecebfe9684a0b73b664"); ++ /* post-merge */ ++ strset_add(&safe_hook_sha256s, "75da0da66a803b4b030ad50801ba57062c6196105eb1d2251590d100edb9390b"); ++ git_protected_config(safe_hook_cb, &safe_hook_sha256s); + } + ## t/t1800-hook.sh ## @@ t/t1800-hook.sh: test_expect_success '`safe.hook.sha256` and clone protections' ' 7: c487bd06be8 = 7: bd6d72625f5 hooks(clone protections): simplify templates hooks validation 8: c45c33d8e3f = 8: 4b0a636d41a Revert "Add a helper function to compare file contents"
