2022-02-10fetch: skip computing output width when not printing anythingLibravatar Patrick Steinhardt1-2/+6
When updating references via git-fetch(1), then by default we report to the user which references have been changed. This output is formatted in a nice table such that the different columns are aligned. Because the first column contains abbreviated object IDs we thus need to iterate over all refs which have changed and compute the minimum length for their respective abbreviated hashes. While this effort makes sense in most cases, it is wasteful when the user passes the `--quiet` flag: we don't print the summary, but still compute the length. Skip computing the summary width when the user asked for us to be quiet. This gives us a speedup of nearly 10% when doing a mirror-fetch in a repository with thousands of references being updated: Benchmark 1: git fetch --quiet +refs/*:refs/* (HEAD~) Time (mean ± σ): 96.078 s ± 0.508 s [User: 91.378 s, System: 10.870 s] Range (min … max): 95.449 s … 96.760 s 5 runs Benchmark 2: git fetch --quiet +refs/*:refs/* (HEAD) Time (mean ± σ): 88.214 s ± 0.192 s [User: 83.274 s, System: 10.978 s] Range (min … max): 87.998 s … 88.446 s 5 runs Summary 'git fetch --quiet +refs/*:refs/* (HEAD)' ran 1.09 ± 0.01 times faster than 'git fetch --quiet +refs/*:refs/* (HEAD~)' Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-02-08checkout/fetch/pull/pack-objects: allow `-h` outside a repositoryLibravatar Johannes Schindelin4-10/+17
When we taught these commands about the sparse index, we did not account for the fact that the `cmd_*()` functions _can_ be called without a gitdir, namely when `-h` is passed to show the usage. A plausible approach to address this is to move the `prepare_repo_settings()` calls right after the `parse_options()` calls: The latter will never return when it handles `-h`, and therefore it is safe to assume that we have a `gitdir` at that point, as long as the built-in is marked with the `RUN_SETUP` flag. However, it is unfortunately not that simple. In `cmd_pack_objects()`, for example, the repo settings need to be fully populated so that the command-line options `--sparse`/`--no-sparse` can override them, not the other way round. Therefore, we choose to imitate the strategy taken in `cmd_diff()`, where we simply do not bother to prepare and initialize the repo settings unless we have a `gitdir`.

2022-02-06ls-remote & transport API: release "struct transport_ls_refs_options"Libravatar Ævar Arnfjörð Bjarmason3-9/+9
Fix a memory leak in codepaths that use the "struct transport_ls_refs_options" API. Since the introduction of the struct in 39835409d10 (connect, transport: encapsulate arg in struct, 2021-02-05) the caller has been responsible for freeing it. That commit in turn migrated code originally added in 402c47d9391 (clone: send ref-prefixes when using protocol v2, 2018-07-20) and b4be74105fe (ls-remote: pass ref prefixes when requesting a remote's refs, 2018-03-15). Only some of those codepaths were releasing the allocated resources of the struct, now all of them will. Mark the "t/t5511-refspec.sh" test as passing when git is compiled with SANITIZE=leak. They'll now be listed as running under the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI target). Previously 24/47 tests would fail.

2022-02-04branch: add --recurse-submodules option for branch creationLibravatar Glen Choo2-6/+76
To improve the submodules UX, we would like to teach Git to handle branches in submodules. Start this process by teaching "git branch" the --recurse-submodules option so that "git branch --recurse-submodules topic" will create the `topic` branch in the superproject and its submodules. Although this commit does not introduce breaking changes, it does not work well with existing --recurse-submodules commands because "git branch --recurse-submodules" writes to the submodule ref store, but most commands only consider the superproject gitlink and ignore the submodule ref store. For example, "git checkout --recurse-submodules" will check out the commits in the superproject gitlinks (and put the submodules in detached HEAD) instead of checking out the submodule branches. Because of this, this commit introduces a new configuration value, `submodule.propagateBranches`. The plan is for Git commands to prioritize submodule ref store information over superproject gitlinks if this value is true. Because "git branch --recurse-submodules" writes to submodule ref stores, for the sake of clarity, it will not function unless this configuration value is set. This commit also includes changes that support working with submodules from a superproject commit because "branch --recurse-submodules" (and future commands) need to read .gitmodules and gitlinks from the superproject commit, but submodules are typically read from the filesystem's .gitmodules and the index's gitlinks. These changes are: * add a submodules_of_tree() helper that gives the relevant information of an in-tree submodule (e.g. path and oid) and initializes the repository * add is_tree_submodule_active() by adding a treeish_name parameter to is_submodule_active() * add the "submoduleNotUpdated" advice to advise users to update the submodules in their trees Incidentally, fix an incorrect usage string that combined the 'list' usage of git branch (-l) with the 'create' usage; this string has been incorrect since its inception, a8dfd5eac4 (Make builtin-branch.c use parse_options., 2007-10-07).

2022-02-02patch-id: fix scan_hunk_header on diffs with 1 line of before/afterLibravatar Jerry Zhang1-2/+7
Normally diffs will contain a hunk header of the format "@@ -2,2 +2,15 @@ code". However when there is only 1 line of change, the unified diff format allows for the second comma separated value to be omitted in either before or after line counts. This can produce hunk headers that look like "@@ -2 +2,18 @@ code" or "@@ -2,2 +2 @@ code". As a result, scan_hunk_header mistakenly returns the line number as line count, which then results in unpredictable parsing errors with the rest of the patch, including giving multiple lines of output for a single commit. Fix by explicitly setting line count to 1 when there is no comma, and add a test. apply.c contains this same logic except it is correct. A worthwhile future project might be to unify these two diff parsers so they both benefit from fixes. Signed-off-by: Jerry Zhang <jerry@skydio.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-02ll-merge: make callers responsible for showing warningsLibravatar Elijah Newren1-4/+8
Since some callers may want to send warning messages to somewhere other than stdout/stderr, stop printing "warning: Cannot merge binary files" from ll-merge and instead modify the return status of ll_merge() to indicate when a merge of binary files has occurred. Message printing probably does not belong in a "low-level merge" anyway. This commit continues printing the message as-is, just from the callers instead of within ll_merge(). Future changes will start handling the message differently in the merge-ort codepath. There was one special case here: the callers in rerere.c do NOT check for and print such a message; since those code paths explicitly skip over binary files, there is no reason to check for a return status of LL_MERGE_BINARY_CONFLICT or print the related message. Note that my methodology included first modifying ll_merge() to return a struct, so that the compiler would catch all the callers for me and ensure I had modified all of them. After modifying all of them, I then changed the struct to an enum. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-02log: clean unneeded objects during `log --remerge-diff`Libravatar Elijah Newren1-6/+7
The --remerge-diff option will need to create new blobs and trees representing the "automatic merge" state. If one is traversing a long project history, one can easily get hundreds of thousands of loose objects generated during `log --remerge-diff`. However, none of those loose objects are needed after we have completed our diff operation; they can be summarily deleted. Add a new helper function to tmp_objdir to discard all the contained objects, and call it after each merge is handled.

2022-02-02show, log: provide a --remerge-diff capabilityLibravatar Elijah Newren1-0/+14
When this option is specified, we remerge all (two parent) merge commits and diff the actual merge commit to the automatically created version, in order to show how users removed conflict markers, resolved the different conflict versions, and potentially added new changes outside of conflict regions in order to resolve semantic merge problems (or, possibly, just to hide other random changes). This capability works by creating a temporary object directory and marking it as the primary object store. This makes it so that any blobs or trees created during the automatic merge are easily removable afterwards by just deleting all objects from the temporary object directory. There are a few ways that this implementation is suboptimal: * `log --remerge-diff` becomes slow, because the temporary object directory can fill with many loose objects while running * the log output can be muddied with misplaced "warning: cannot merge binary files" messages, since ll-merge.c unconditionally writes those messages to stderr while running instead of allowing callers to manage them. * important conflict and warning messages are simply dropped; thus for conflicts like modify/delete or rename/rename or file/directory which are not representable with content conflict markers, there may be no way for a user of --remerge-diff to know that there had been a conflict which was resolved (and which possibly motivated other changes in the merge commit). * when fixing the previous issue, note that some unimportant conflict and warning messages might start being included. We should instead make sure these remain dropped. Subsequent commits will address these issues. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-01receive-pack: purge temporary data if no command is ready to runLibravatar Chen Bojun1-0/+9
When pushing a hidden ref, e.g.: $ git push origin HEAD:refs/hidden/foo "receive-pack" will reject our request with an error message like this: ! [remote rejected] HEAD -> refs/hidden/foo (deny updating a hidden ref) The remote side ("git-receive-pack") will not create the hidden ref as expected, but the pack file sent by "git-send-pack" is left inside the remote repository. I.e. the quarantine directory is not purged as it should be. Add a checkpoint before calling "tmp_objdir_migrate()" and after calling the "pre-receive" hook to purge that temporary data in the quarantine area when there is no command ready to run. The reason we do not add the checkpoint before the "pre-receive" hook, but after it, is that the "pre-receive" hook is called with a switch-off "skip_broken" flag, and all commands, even broken ones, should be fed by calling "feed_receive_hook()".

2022-01-27stash: stop warning about the obsolete `stash.useBuiltin` config settingLibravatar Johannes Schindelin1-10/+0
In 8a2cd3f5123 (stash: remove the stash.useBuiltin setting, 2020-03-03), we removed support for `stash.useBuiltin`, but left a warning in its place. After almost two years, and several major versions, it is time to remove even that warning.

2022-01-27add: remove support for `git-legacy-stash`Libravatar Johannes Schindelin1-14/+0
In 90a6bb98d11 (legacy stash -p: respect the add.interactive.usebuiltin setting, 2019-12-21), we added support to use the built-in `add -p` from the scripted `stash -p`. In 8a2cd3f5123 (stash: remove the stash.useBuiltin setting, 2020-03-03), we retired the scripted `stash` (including the scripted `stash -p`). Therefore this support is no longer necessary.
