2018-03-06Merge branch 'jc/allow-ff-merging-kept-tags'Libravatar Junio C Hamano1-4/+39
Since Git 1.7.9, "git merge" defaulted to --no-ff (i.e. even when the side branch being merged is a descendant of the current commit, create a merge commit instead of fast-forwarding) when merging a tag object. This was appropriate default for integrators who pull signed tags from their downstream contributors, but caused an unnecessary merges when used by downstream contributors who habitually "catch up" their topic branches with tagged releases from the upstream. Update "git merge" to default to --no-ff only when merging a tag object that does *not* sit at its usual place in refs/tags/ hierarchy, and allow fast-forwarding otherwise, to mitigate the problem. * jc/allow-ff-merging-kept-tags: merge: allow fast-forward when merging a tracked tag
2018-03-01write_locked_index(): add flag to avoid writing unchanged indexLibravatar Martin Ågren1-9/+6
We have several callers like if (active_cache_changed && write_locked_index(...)) handle_error(); rollback_lock_file(...); where the final rollback is needed because "!active_cache_changed" shortcuts the if-expression. There are also a few variants of this, including some if-else constructs that make it more clear when the explicit rollback is really needed. Teach `write_locked_index()` to take a new flag SKIP_IF_UNCHANGED and simplify the callers. Leave the most complicated of the callers (in builtin/update-index.c) unchanged. Rewriting it to use this new flag would end up duplicating logic. We could have made the new flag behave the other way round ("FORCE_WRITE"), but that could break existing users behind their backs. Let's take the more conservative approach. We can still migrate existing callers to use our new flag. Later we might even be able to flip the default, possibly without entirely ignoring the risk to in-flight or out-of-tree topics.

2018-02-16merge: allow fast-forward when merging a tracked tagLibravatar Junio C Hamano1-4/+39
Long time ago at fab47d05 ("merge: force edit and no-ff mode when merging a tag object", 2011-11-07), "git merge" was made to always create a merge commit when merging a tag, even when the side branch being merged is a descendant of the current branch. This default is good for merges made by upstream maintainers to integrate work signed by downstream contributors, but will leave pointless no-ff merges when downstream contributors pull a newer release tag to make their long-running topic branches catch up with the upstream. When there is no local work left on the topic, such a merge should simply fast-forward to the commit pointed at by the release tag. Update the default (again) for "git merge" that merges a tag object to (1) --no-ff (i.e. create a merge commit even when side branch fast forwards) if the tag being merged is not at its expected place in refs/tags/ hierarchy and (2) --ff (i.e. allow fast-forward update when able) otherwise.

2017-09-08builtin/merge: honor commit-msg hook for mergesLibravatar Stefan Beller1-0/+8
Similar to 65969d43d1 (merge: honor prepare-commit-msg hook, 2011-02-14) merge should also honor the commit-msg hook: When a merge is stopped due to conflicts or --no-commit, the subsequent commit calls the commit-msg hook. However, it is not called after a clean merge. Fix this inconsistency by invoking the hook after clean merges as well. This change is motivated by Gerrit's commit-msg hook to install a ChangeId trailer into the commit message. Without such a ChangeId, Gerrit refuses to accept any commit by default, such that the inconsistency of (not) running the commit-msg hook between commit and merge leads to confusion and might block people from getting their work done. As the githooks man page is very vocal about the possibility of skipping the commit-msg hook via the --no-verify option, implement the option in merge, too. 'git merge --continue' is currently implemented as calling cmd_commit with no further arguments. This works for most other merge related options, such as demonstrated via the --allow-unrelated-histories flag in the test. The --no-verify option however is not remembered across invocations of git-merge. Originally the author assumed an alternative in which the 'git merge --continue' command accepts the --no-verify flag, but that opens up the discussion which flags are allows to the continued merge command and which must be given in the first invocation.

2017-08-23merge: save merge state earlierLibravatar Michael J Gruber1-0/+2
If the `git merge` process is killed while waiting for the editor to finish, the merge state is lost but the prepared merge msg and tree is kept. So, a subsequent `git commit` creates a squashed merge even when the user asked for proper merge commit originally. Demonstrate the problem with a test crafted after the in t7502. The test requires EXECKEEPSPID (thus does not run under MINGW). Save the merge state earlier (in the non-squash case) so that it does not get lost. This makes the test pass.

2017-08-23merge: split write_merge_state in twoLibravatar Michael J Gruber1-3/+8
write_merge_state() writes out the merge heads, mode, and msg. But we may want to write out heads, mode without the msg. So, split out heads (+mode) into a separate function write_merge_heads() that is called by write_merge_state(). No funtional change so far, except when these non-atomic writes are interrupted: we write heads-mode-msg now when we used to write heads-msg-mode.

2017-08-23merge: clarify call chainLibravatar Michael J Gruber1-0/+2
prepare_to_commit() cannot be reached in the non-squash case: It is called by merge_trivial() and finish_automerge() only, but the calls to the latter are somewhat hard to track: If option_commit is not set, the code in cmd_merge() uses a fake conflict return code (ret=1) to avoid writing the tree, which also avoids setting automerge_was_ok (just as in the proper ret==1 case), so that finish_automerge() is not called. To ensure that no code change breaks that assumption, safe-guard prepare_to_commit() by a BUG() statement.

2017-05-08Convert lookup_commit* to struct object_idLibravatar brian m. carlson1-1/+1
Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch.

2017-03-26Convert GIT_SHA1_HEXSZ used for allocation to GIT_MAX_HEXSZLibravatar brian m. carlson1-1/+1
Since we will likely be introducing a new hash function at some point, and that hash function might be longer than 40 hex characters, use the constant GIT_MAX_HEXSZ, which is designed to be suitable for allocations, instead of GIT_SHA1_HEXSZ. This will ease the transition down the line by distinguishing between places where we need to allocate memory suitable for the largest hash from those where we need to handle the current hash.
