Running `git remote add --mirror -f origin ../one` will not change HEAD, consequently if init.defaultBranch is not the same as what HEAD in the remote ("one"), HEAD in "mirror" will be pointing to a non-existent reference. Hence if "mirror" is used as a remote by yet another repository, ls-remote will not show HEAD. On the other hand, if init.defaultBranch happens to match HEAD in "one", then ls-remote will show HEAD. Since the CI globally exports GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main, there's a drift between how the test repositories are set up in the CI and during local testing. This issue does not manifest currently, as the test does not do any remote HEAD manipulation where this would come up, but should such things be added, a locally passing test would break the CI vice-versa. Set GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main in the test to be consistent with the CI. --- Notes: v9: - new patch - a bandaid for the CI issue noticed by Taylor (cf: https://lore.kernel.org/git/Zw8IKyPkG0Hr6%2F5t@nand.local/), but see https://lore.kernel.org/git/D4ZAELFWJMKN.S88LJ6YK31LZ@ferdinandy.com/ for the root cause in detail t/t5505-remote.sh | 3 +++ 1 file changed, 3 insertions(+) diff --git a/t/t5505-remote.sh b/t/t5505-remote.sh index 532035933f..9b50276646 100755 --- a/t/t5505-remote.sh +++ b/t/t5505-remote.sh @@ -2,6 +2,9 @@ test_description='git remote porcelain-ish' +GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main +export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME + TEST_PASSES_SANITIZE_LEAK=true . ./test-lib.sh From patchwork Sat Oct 19 22:53:09 2024 Content-Type: text/plain;

Extend refs_update_symref under a new function name, to record the value after the ref has been locked if the caller of refs_update_symref_extended requests it via a new variable in the function call. Keep the original refs_update_symref function with the same signature, but now as a wrapper around refs_update_symref_extended. Signed-off-by: Bence Ferdinandy --- Notes: v4: new patch v5: - added before_target to reftables backend - added an extra safety check for transaction's existence in refs.c v6: - no change v7: - remove the whole before_target concept from the backends and handle checking it in refs.c instead (thanks Karthik) - rename the before_target to referent which is how the same concept is called in the backends - change commit prefix to be more in line with project standards v8: no change v9: - instead of adding parameters to refs_update_symref, rename what was in v8 as refs_update_symref_extended and make refs_update_symref a wrapper for that. This significantly reduces the number of files that need to be touched, and avoids adding a lot of dummy NULL-s in unrelated places. refs.c | 19 ++++++++++++++++--- refs.h | 4 ++++ 2 files changed, 20 insertions(+), 3 deletions(-) diff --git a/refs.c b/refs.c index 5f729ed412..24a4172cd2 100644 --- a/refs.c +++ b/refs.c @@ -2115,6 +2115,13 @@ int peel_iterated_oid(struct repository *r, const struct object_id *base, struct int refs_update_symref(struct ref_store *refs, const char *ref, const char *target, const char *logmsg) +{ + return refs_update_symref_extended(refs, ref, target, logmsg, NULL);

Instead of calling get_main_ref_store(the_repository) multiple times, call it once and store in a new refs variable. Although this change probably offers some performance benefits, the main purpose is to shorten the line lengths of function calls using this variable.

Change the output of --auto, so the output actually reflects what was done: a) set a previously unset HEAD, b) change HEAD because remote changed or c) no updates. As a fourth output, if HEAD is changed from a previous value that was not a remote branch, explicitly call attention to this fact. Signed-off-by: Bence Ferdinandy --- Notes: v1-v2: was RFC in https://lore.kernel.org/git/20240910203835.2288291-1-bence@ferdinandy.com/ v3: This patch was originally sent along when I thought set-head was going to be invoked by fetch, but the discussion on the RFC concluded that it should be not. This opened the possibility to make it more explicit. Note: although I feel both things the patch does are really just cosmetic, an argument could be made for breaking it into two, one for the no-op part and one for the --auto print update.

Silently pass if the user already has the same remote/HEAD set as reported by the server or if we encounter any errors along the way. Signed-off-by: Bence Ferdinandy --- Notes: v3: - does not rely on remote set-head anymore so it only authenticates once - uses the new REF_CREATE_ONLY to atomically check if the ref exists and only write it if it doesn't - in all other cases the maximum it does is print a warning v4: - instead of the discarded REF_CREATE_ONLY, it uses the existing, but updated transaction api to request a silent create only - it now uses the atomic before_target to determine reporting - refactored for legibility v5: - instead of printing a not too useful message, it now fails silently, this in line with the objective to only set up remote/HEAD automatically if the right thing is trivial, for everything else there is remote set-head - fixed all failing tests - added two new tests, one for checking if remote/HEAD is set to the correct one, and one to test that we do not override remote/HEAD if it has changed on the server from what we have locally v6: - fixed style issues and unintended extra empty line - updated function call with bool to int from previous patch's change - removed calls to error(...) inherited from builtin/remote.c so we actually fail silently - set the test for remote set-head --auto to the correct value here, which was previously erronously set in the remote set-head patch v7: - no change v8: - changed logmsg in call to refs_update_symref from "remote set-head" to "fetch" v9: - follow through with refs_update_symref_extended - fix test errors uncovered by the new patch builtin/fetch.c | 82 +++++++++++ t/t4207-log-decoration-colors.sh | 3 +- t/t5505-remote.sh | 21 ++-
