2025-04-08builtin/merge-recursive: switch to using merge_ort_generic()Elijah Newren
Switch from merge-recursive to merge-ort. Adjust the following testcases due to the switch: * t6430: most of the test differences here were due to improved D/F conflict handling explained in more detail in ef527787089c (merge tests: expect improved directory/file conflict handling in ort, 2020-10-26). These changes weren't made to this test back in that commit simply because I had been looking at `git merge` rather than `git merge-recursive`. The final test in this testsuite, though, was expunged because it was looking for specific output, and the calls to output_commit_title() were discarded from merge_ort_internal() in its adaptation from merge_recursive_internal(); see 8119214f4e70 (merge-ort: implement merge_incore_recursive(), 2020-12-16). * t6434: This test is built entirely around rename/delete conflicts, which had a suboptimal handling under merge-recursive. As explained in more detail in commits 1f3c9ba707 ("t6425: be more flexible with rename/delete conflict messages", 2020-08-10) and 727c75b23f ("t6404, t6423: expect improved rename/delete handling in ort backend", 2020-10-26), rename/delete conflicts should each have two entries in the index rather than just one. Adjust the expectations for all the tests in this testcase to see the two entries per rename/delete conflict. * t6424: merge-recursive had a special check-if-toplevel-trees-match check that it ran at the beginning on both the merge-base and the other side being merged in. In such a case, it exited early and printed an "Already up to date." message. merge-ort got rid of this, and instead checks the merge base tree matching the other side throughout the tree instead of just at the toplevel, allowing it to avoid recursing into various subtrees. As part of that, it got rid of the specialty toplevel message. That message hasn't been missed for years from `git merge`, so I don't think it is necessary to keep it just for `git merge-recursive`, especially since the latter is rarely used. (git itself only references it in the testsuite, whereas it used to power one of the three rebase backends that existed once upon a time.)

2025-01-17builtin: send usage() help text to standard outputJunio C Hamano
Using the show_usage_and_exit_if_asked() helper we introduced earlier, fix callers of usage() that want to show the help text when explicitly asked by the end-user. The help text now goes to the standard output stream for them. These are the bog standard "if we got only '-h', then that is a request for help" callers. Their if (argc == 2 && !strcmp(argv[1], "-h")) usage(message); are simply replaced with show_usage_and_exit_if_asked(argc, argv, message); With this, the built-ins tested by t0012 all send their help text to their standard output stream, so the check in t0012 that was half tightened earlier is now fully tightened to insist on standard error stream being empty.

2024-09-13builtin: remove USE_THE_REPOSITORY_VARIABLE from builtin.hJohn Cai
Instead of including USE_THE_REPOSITORY_VARIABLE by default on every builtin, remove it from builtin.h and add it to all the builtins that include builtin.h (by definition, that means all builtins/*.c). Also, remove the include statement for repository.h since it gets brought in through builtin.h. The next step will be to migrate each builtin from having to use the_repository.

2024-07-13merge-recursive: honor diff.algorithmAntonin Delpeuch
The documentation claims that "recursive defaults to the diff.algorithm config setting", but this is currently not the case. This fixes it, ensuring that diff.algorithm is used when -Xdiff-algorithm is not supplied. This affects the following porcelain commands: "merge", "rebase", "cherry-pick", "pull", "stash", "log", "am" and "checkout". It also affects the "merge-tree" ancillary interrogator. This change refactors the initialization of merge options to introduce two functions, "init_merge_ui_options" and "init_merge_basic_options" instead of just one "init_merge_options". This design follows the approach used in diff.c, providing initialization methods for porcelain and plumbing commands respectively. Thanks to that, the "replay" and "merge-recursive" plumbing commands remain unaffected by diff.algorithm.

2024-06-11builtin/merge-recursive: fix leaking object ID basesPatrick Steinhardt
In `cmd_merge_recursive()` we have a static array of object ID bases that we pass to `merge_recursive_generic()`. This interface is somewhat weird though because the latter function accepts a pointer to a pointer of object IDs, which requires us to allocate the object IDs on the heap. And as we never free those object IDs, the end result is a leak. While we can easily solve this leak by just freeing the respective object IDs, the whole calling convention is somewhat weird. Instead, refactor `merge_recursive_generic()` to accept a plain pointer to object IDs so that we can avoid allocating them altogether.

2023-04-24hash-ll.h: split out of hash.h to remove dependency on repository.hElijah Newren
hash.h depends upon and includes repository.h, due to the definition and use of the_hash_algo (defined as the_repository->hash_algo). However, most headers trying to include hash.h are only interested in the layout of the structs like object_id. Move the parts of hash.h that do not depend upon repository.h into a new file hash-ll.h (the "low level" parts of hash.h), and adjust other files to use this new header where the convenience inline functions aren't needed. This allows hash.h and object.h to be fairly small, minimal headers. It also exposes a lot of hidden dependencies on both path.h (which was brought in by repository.h) and repository.h (which was previously implicitly brought in by object.h), so also adjust other files to be more explicit about what they depend upon.

2023-03-28builtins: mark unused prefix parametersJeff King
All builtins receive a "prefix" parameter, but it is only useful if they need to adjust filenames given by the user on the command line. For builtins that do not even call parse_options(), they often don't look at the prefix at all, and -Wunused-parameter complains. Let's annotate those to silence the compiler warning. I gave a quick scan of each of these cases, and it seems like they don't have anything they _should_ be using the prefix for (i.e., there is no hidden bug that we are missing). The only questionable cases I saw were: - in git-unpack-file, we create a tempfile which will always be at the root of the repository, even if the command is run from a subdir. Arguably this should be created in the subdir from which we're run (as we report the path only as a relative name). However, nobody has complained, and I'm hesitant to change something that is deep plumbing going back to April 2005 (though I think within our scripts, the sole caller in git-merge-one-file would be OK, as it moves to the toplevel itself). - in fetch-pack, local-filesystem remotes are taken as relative to the project root, not the current directory. So: git init server.git [...put stuff in server.git...] git init client.git cd client.git mkdir subdir cd subdir git fetch-pack ../../server.git ... won't work, as we quietly move to the top of the repository before interpreting the path (so "../server.git" would work). This is weird, but again, nobody has complained and this is how it has always worked. And this is how "git fetch" works, too. Plus it raises questions about how a configured remote like: git config remote.origin.url ../server.git should behave. I can certainly come up with a reasonable set of behavior, but it may not be worth stirring up complications in a plumbing tool. So I've left the behavior untouched in both of those cases. If anybody really wants to revisit them, it's easy enough to drop the UNUSED marker. This commit is just about removing them as obstacles to turning on -Wunused-parameter all the time.

Change a few stray users of the inline gettext.h Q_() function to stop casting its "n" argument, the vast majority of the users of that wrapper API use the implicit cast to "unsigned long". The ngettext() function (which Q_() resolves to) takes an "unsigned long int", and so does our Q_() wrapper for it, see 0c9ea33b90f (i18n: add stub Q_() wrapper for ngettext, 2011-03-09). The function isn't ours, but provided by e.g. GNU libintl. This amends code added in added in 7171a0b0cf5 (index-pack: correct "len" type in unpack_data(), 2016-07-13). The cast it added for the printf format to die() was needed, but not the cast to Q_(). Likewise the casts in strbuf.c added in 8f354a1faed (l10n: localizable upload progress messages, 2019-07-02) and for builtin/merge-recursive.c in ccf7813139f (i18n: merge-recursive: mark error messages for translation, 2016-09-15) weren't needed. In the latter case the cast was copy/pasted from the argument to warning() itself, added in b74d779bd90 (MinGW: Fix compiler warning in merge-recursive, 2009-05-23).

2019-08-19Ensure index matches head before invoking merge machinery, round NElijah Newren
This is the bug that just won't die; there always seems to be another form of it somewhere. See the commit message of 55f39cf7551b ("merge: fix misleading pre-merge check documentation", 2018-06-30) for a more detailed explanation), but in short: <quick summary> builtin/merge.c contains this important requirement for merge strategies: ...the index must be in sync with the head commit. The strategies are responsible to ensure this. This condition is important to enforce because there are two likely failure cases when the index isn't in sync with the head commit: * we silently throw away changes the user had staged before the merge * we accidentally (and silently) include changes in the merge that were not part of either of the branches/trees being merged Discarding users' work and mis-merging are both bad outcomes, especially when done silently, so naturally this rule was stated sternly -- but, unfortunately totally ignored in practice unless and until actual bugs were found. But, fear not: the bugs from this were fixed in commit ee6566e8d70d ("[PATCH] Rewrite read-tree", 2005-09-05) through a rewrite of read-tree (again, commit 55f39cf7551b has a more detailed explanation of how this affected merge). And it was fixed again in commit 160252f81626 ("git-merge-ours: make sure our index matches HEAD", 2005-11-03) ...and it was fixed again in commit 3ec62ad9ffba ("merge-octopus: abort if index does not match HEAD", 2016-04-09) ...and again in commit 65170c07d466 ("merge-recursive: avoid incorporating uncommitted changes in a merge", 2017-12-21) ...and again in commit eddd1a411d93 ("merge-recursive: enforce rule that index matches head before merging", 2018-06-30) ...with multiple testcases added to the testsuite that could be enumerated in even more commits. Then, finally, in a patch in the same series as the last fix above, the documentation about this requirement was fixed in commit 55f39cf7551b ("merge: fix misleading pre-merge check documentation", 2018-06-30), and we all lived happily ever after... </quick summary> Unfortunately, "ever after" apparently denotes a limited time and it expired today. The merge-recursive rule to enforce that index matches head was at the beginning of merge_trees() and would only trigger when opt->call_depth was 0. Since merge_recursive() doesn't call merge_trees() until after returning from recursing, this meant that the check wasn't triggered by merge_recursive() until it had first finished all the intermediate merges to create virtual merge bases. That is a potentially HUGE amount of computation (and writing of intermediate merge results into the .git/objects directory) before it errors out and says, in effect, "Sorry, I can't do any merging because you have some local changes that would be overwritten." Trying to enforce that all of merge_trees(), merge_recursive(), and merge_recursive_generic() checked the index == head condition earlier resulted in a bunch of broken tests. It turns out that merge_recursive() has code to drop and reload the cache while recursing to create intermediate virtual merge bases, but unfortunately that code runs even when no recursion is necessary. This unconditional dropping and reloading of the cache masked a few bugs: * builtin/merge-recursive.c: didn't even bother loading the index. * builtin/stash.c: feels like a fake 'builtin' because it repeatedly invokes git subprocesses all over the place, mixed with other operations. In particular, invoking "git reset" will reset the index on disk, but the parent process that invoked it won't automatically have its in-memory index updated. * t3030-merge-recursive.h: this test has always been broken in that it didn't make sure to make index match head before running. But, it didn't care about the index or even the merge result, just the verbose output while running. While commit eddd1a411d93 ("merge-recursive: enforce rule that index matches head before merging", 2018-06-30) should have uncovered this broken test, it used a test_must_fail wrapper around the merge-recursive call because it was known that the merge resulted in a rename/rename conflict. Thus, that fix only made this test fail for a different reason, and since the index == head check didn't happen until after coming all the way back out of the recursion, the testcase had enough information to pass the one check that it did perform. So, load the index in builtin/merge-recursive.c, reload the in-memory index in builtin/stash.c, and modify the t3030 testcase to correctly setup the index and make sure that the test fails in the expected way (meaning it reports a rename/rename conflict). This makes sure that all callers actually make the index match head. The next commit will then enforce the condition that index matches head earlier so this problem doesn't return in the future.

2015-09-25convert trivial sprintf / strcpy calls to xsnprintfJeff King
We sometimes sprintf into fixed-size buffers when we know that the buffer is large enough to fit the input (either because it's a constant, or because it's numeric input that is bounded in size). Likewise with strcpy of constant strings. However, these sites make it hard to audit sprintf and strcpy calls for buffer overflows, as a reader has to cross-reference the size of the array with the input. Let's use xsnprintf instead, which communicates to a reader that we don't expect this to overflow (and catches the mistake in case we do).

Fix warnings from 'make check'. - These files don't include 'builtin.h' causing sparse to complain that cmd_* isn't declared: builtin/clone.c:364, builtin/fetch-pack.c:797, builtin/fmt-merge-msg.c:34, builtin/hash-object.c:78, builtin/merge-index.c:69, builtin/merge-recursive.c:22 builtin/merge-tree.c:341, builtin/mktag.c:156, builtin/notes.c:426 builtin/notes.c:822, builtin/pack-redundant.c:596, builtin/pack-refs.c:10, builtin/patch-id.c:60, builtin/patch-id.c:149, builtin/remote.c:1512, builtin/remote-ext.c:240, builtin/remote-fd.c:53, builtin/reset.c:236, builtin/send-pack.c:384, builtin/unpack-file.c:25, builtin/var.c:75 - These files have symbols which should be marked static since they're only file scope: submodule.c:12, diff.c:631, replace_object.c:92, submodule.c:13, submodule.c:14, trace.c:78, transport.c:195, transport-helper.c:79, unpack-trees.c:19, url.c:3, url.c:18, url.c:104, url.c:117, url.c:123, url.c:129, url.c:136, thread-utils.c:21, thread-utils.c:48 - These files redeclare symbols to be different types: builtin/index-pack.c:210, parse-options.c:564, parse-options.c:571, usage.c:49, usage.c:58, usage.c:63, usage.c:72 - These files use a literal integer 0 when they really should use a NULL pointer: daemon.c:663, fast-import.c:2942, imap-send.c:1072, notes-merge.c:362 While we're in the area, clean up some unused #includes in builtin files (mostly exec_cmd.h).

2010-09-03builtin/merge_recursive.c: Add an usage string and make use of it.Thiago Farina
This improves the usage output by adding builtin_merge_recursive_usage string that follows the same pattern used by the other builtin commands. The previous output for git merger-recursive was: usage: merge-recursive <base>... -- <head> <remote> ... Now the output is: usage: git merge-recursive <base>... -- <head> <remote> ... Since cmd_merge_recursive is used to handle four different commands we need the %s in the usage string, so the following example: $ git merge-subtree -h Will output: usage: git merge-subtree <base>... -- <head> <remote> ...

2010-08-26merge-recursive --patienceJustin Frankel
Teach the merge-recursive strategy a --patience option to use the "patience diff" algorithm, which tends to improve results when cherry-picking a patch that reorders functions at the same time as refactoring them. To support this, struct merge_options and ll_merge_options gain an xdl_opts member, so programs can use arbitrary xdiff flags (think "XDF_IGNORE_WHITESPACE") in a git-aware merge. git merge and git rebase can be passed the -Xpatience option to use this.

2010-08-26merge-recursive: expose merge options for builtin mergeJonathan Nieder
There are two very similar blocks of code that recognize options for the "recursive" merge strategy. Unify them. No functional change intended.

2010-08-06merge-recursive --renormalizeJonathan Nieder
Teach "git merge-recursive" a --renormalize option to enable the merge.renormalize configuration. The --no-renormalize option can be used to override it in the negative. So in the future, you might be able to, e.g.: git checkout -m -Xrenormalize otherbranch or git revert -Xrenormalize otherpatch or git pull --rebase -Xrenormalize The bad part: merge.renormalize is still not honored for most commands. And it reveals lots of places that -X has not been plumbed in (so we get "git merge -Xrenormalize" but not much else).

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds
This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
