2025-09-17whatchanged: hint about git-log(1) and aliasingKristoffer Haugsbakk2-2/+8
There have been quite a few `--i-still-use-this` user reports since Git 2.51.0 was released.[1][2] And it doesn’t seem like they are reading the man page about the git-log(1) equivalent. Tell them what options to plug into git-log(1), either as a replacement command or as an alias.[3] That template produces almost the same output[4] and is arguably a plug-in replacement. Concretely, add an optional `hint` argument so that we can use it right after the initial error line. Also mention the same concrete options in the documentation while we’re at it.

2025-09-17refs/files: catch conflicts on case-insensitive file-systemsKarthik Nayak1-3/+18
During the 'prepare' phase of a reference transaction in the files backend, we create the lock files for references to be created. When using batched updates on case-insensitive filesystems, the entire batched updates would be aborted if there are conflicting names such as: refs/heads/Foo refs/heads/foo This affects all commands which were migrated to use batched updates in Git 2.51, including 'git-fetch(1)' and 'git-receive-pack(1)'. Before that, reference updates would be applied serially with one transaction used per update. When users fetched multiple references on case-insensitive systems, subsequent references would simply overwrite any earlier references. So when fetching: refs/heads/foo: 5f34ec0bfeac225b1c854340257a65b106f70ea6 refs/heads/Foo: ec3053b0977e83d9b67fc32c4527a117953994f3 refs/heads/sample: 2eefd1150e06d8fca1ddfa684dec016f36bf4e56 The user would simply end up with: refs/heads/foo: ec3053b0977e83d9b67fc32c4527a117953994f3 refs/heads/sample: 2eefd1150e06d8fca1ddfa684dec016f36bf4e56 This is buggy behavior since the user is never informed about the overrides performed and missing references. Nevertheless, the user is left with a working repository with a subset of the references. Since Git 2.51, in such situations fetches would simply fail without updating any references. Which is also buggy behavior and worse off since the user is left without any references. The error is triggered in `lock_raw_ref()` where the files backend attempts to create a lock file. When a lock file already exists the function returns a 'REF_TRANSACTION_ERROR_GENERIC'. When this happens, the entire batched updates, not individual operation, is aborted as if it were in a transaction. Change this to return 'REF_TRANSACTION_ERROR_CASE_CONFLICT' instead to aid the batched update mechanism to simply reject such errors. The change only affects batched updates since batched updates will reject individual updates with non-generic errors. So specifically this would only affect: 1. git fetch 2. git receive-pack 3. git update-ref --batch-updates This bubbles the error type up to `files_transaction_prepare()` which tries to lock each reference update. So if the locking fails, we check if the rejection type can be ignored, which is done by calling `ref_transaction_maybe_set_rejected()`. As the error type is now 'REF_TRANSACTION_ERROR_CASE_CONFLICT', the specific reference update would simply be rejected, while other updates in the transaction would continue to be applied. This allows partial application of references in case-insensitive filesystems when fetching colliding references. While the earlier implementation allowed the last reference to be applied overriding the initial references, this change would allow the first reference to be applied while rejecting consequent collisions. This should be an okay compromise since with the files backend, there is no scenario possible where we would retain all colliding references. Let's also be more proactive and notify users on case-insensitive filesystems about such problems by providing a brief about the issue while also recommending using the reftable backend, which doesn't have the same issue.

2025-09-11odb: drop deprecated wrapper functionsPatrick Steinhardt1-3/+3
In the Git 2.51 release cycle we've refactored the object database layer to access objects via `struct object_database` directly. To make the transition a bit easier we have retained some of the old-style functions in case those were widely used. Now that Git 2.51 has been released it's time to clean up though and drop these old wrappers. Do so and adapt the small number of newly added users to use the new functions instead.

2025-09-08stash: pass --no-color to diff plumbing child processesJeff King1-1/+4
After a partial stash, we may clear out the working tree by capturing the output of diff-tree and piping it into git-apply (and likewise we may use diff-index to restore the index). So we most definitely do not want color diff output from that diff-tree process. And it normally would not produce any, since its stdout is not going to a tty, and the default value of color.ui is "auto". However, if GIT_PAGER_IN_USE is set in the environment, that overrides the tty check, and we'll produce a colorized diff that chokes git-apply: $ echo y | GIT_PAGER_IN_USE=1 git stash -p [...] Saved working directory and index state WIP on main: 4f2e2bb foo error: No valid patches in input (allow with "--allow-empty") Cannot remove worktree changes Setting this variable is a relatively silly thing to do, and not something most users would run into. But we sometimes do it in our tests to stimulate color. And it is a user-visible bug, so let's fix it rather than work around it in the tests. The root issue here is that diff-tree (and other diff plumbing) should probably not ever produce color by default. It does so not by parsing color.ui, but because of the baked-in "auto" default from 4c7f1819b3 (make color.ui default to 'auto', 2013-06-10). But changing that is risky; we've had discussions back and forth on the topic over the years. E.g.: https://lore.kernel.org/git/86D0A377-8AFD-460D-A90E-6327C6934DFC@gmail.com/. So let's accept that as the status quo for now and protect ourselves by passing --no-color to the child processes. This is the same thing we did for add-interactive itself in 1c6ffb546b (add--interactive.perl: specify --no-color explicitly, 2020-09-07).

2025-08-09diff: --no-index should ignore the worktreeJunio C Hamano1-0/+15
The act of giving "--no-index" tells Git to pretend that the current directory is not under control of any Git index or repository, so even when you happen to be in a Git controlled working tree, where in that working tree should not matter. But the start-up sequence tries to discover the top of the working tree and chdir(2)'s there, even before Git passes control to the subcommand being run. When diff_no_index() starts running, it starts at a wrong (from the end-user's point of view who thinks "git diff --no-index" is merely a better version of GNU diff) directory, and the original directory the user started the command is at "prefix". Because the paths given from argv[] have already been adjusted to account for this path shuffling by prepending the prefix, and showing the resulting path by stripping the prefix, the effect of these nonsense operations (nonsense in the context of "--no-index", that is) is usually not observable. Except for special cases like "-", where it is not preprocessed by prepending the prefix. Instead of papering over by adding more special cases only to cater to the no-index codepath in the generic code, drive the diff machinery more faithfully to what is going on. If the user started "git diff --no-index" in directory X/Y/Z in a working tree controlled by Git, and the start up sequence of Git chdir(2)'ed up to directory X and left Y/Z in the prefix, revert the effect of the start up sequence by chdir'ing back to Y/Z and emptying the prefix.

2025-08-06builtin/reflog: implement subcommand to write new entriesPatrick Steinhardt1-0/+65
While we provide a couple of subcommands in git-reflog(1) to remove reflog entries, we don't provide any to write new entries. Obviously this is not an operation that really would be needed for many use cases out there, or otherwise people would have complained that such a command does not exist yet. But the introduction of the "reftable" backend changes the picture a bit, as it is now basically impossible to manually append a reflog entry if one wanted to do so due to the binary format. Plug this gap by introducing a simple "write" subcommand. For now, all this command does is to append a single new reflog entry with the given object IDs and message to the reflog. More specifically, it is not yet possible to: - Write multiple reflog entries at once. - Insert reflog entries at arbitrary indices. - Specify the date of the reflog entry. - Insert reflog entries that refer to nonexistent objects. If required, those features can be added at a future point in time. For now though, the new command aims to fulfill the most basic use cases while being as strict as possible when it comes to verifying parameters.

The way subcommands of git-reflog(1) are laid out does not make any immediate sense. Reorder them such that read-only subcommands precede writing commands for a bit more structure. Furthermore, move the "expire" subcommand last. This prepares for a subsequent change where we are about to introduce a new "write" command to append reflog entries. Like this, the writing subcommands are ordered such that those affecting a single reflog come before those spanning across all reflogs.

2025-08-05remote: bail early from set_head() if missing remote nameJeff King1-4/+7
In "git remote set-head", we can take varying numbers of arguments depending on whether we saw the "-d" or "-a" options. But the first argument is always the remote name. The current code is somewhat awkward in that it conditionally handles the remote name up-front like this: if (argc) remote = ...from argv[0]... and then only later decides to bail if we do not have the right number of arguments for the options we saw. This makes it hard to figure out if "remote" is always set when it needs to be. Both for humans, but also for compilers; with -Og, gcc complains that "remote" can be accessed without being initialized (although this is not true, as we'd always die with a usage message in that case). Let's instead enforce the presence of the remote argument up front, which fixes the compiler warning and is easier to understand. It does mean duplicating the code to print a usage message, but it's a single line.

2025-08-04revert: initialize const valueJeff King1-1/+1
When building with clang-22 and DEVELOPER=1 mode, this warning causes us to fail compilation: builtin/revert.c:114:13: error: default initialization of an object of type 'const char' leaves the object uninitialized [-Werror,-Wdefault-const-init-var-unsafe] 114 | const char sentinel_value; | ^ The compiler is right that this code is a bit funny. We declare a const value without an initializer. It cannot be assigned to because of the const, but without an initializer it has no predictable value. So as a variable it can never have any useful function, and if we tried to look at it, we'd get undefined behavior. But it does have a function. We never use its value, but rather use its address as a sentinel value for some other variables: const char *gpg_sign = &sentinel_value; ...maybe set gpg_sign via parse_options... if (gpg_sign != &sentinel_value) ...we got a non-default value... Normally we'd use NULL as a sentinel value for a pointer, but it doesn't work here because we also want to detect --no-gpg-sign, which is marked by setting the pointer to NULL. We need a separate "this was not touched" value, which is what this sentinel variable gives us. So the code is correct as-is, but the sentinel variable itself is funny enough that it's understandable for a compiler warning to flag it. Let's try to appease the compiler. There are a few possible options: 1. Instead of a variable, we could just construct an artificial sentinel address like "1", "-1", etc. I think these technically fall afoul of the C standard (even if we do not access them, even constructing invalid pointers is not always allowed). But it's also something we do elsewhere, and even happens in some standard interfaces (e.g., mmap()'s MMAP_FAILED value). It does involve some annoying casts, though. 2. We can mark it as static. That gives it a definite value, but perhaps makes people wonder if the static-ness is important, when it's not. 3. We can just give it a value to shut the compiler up, even though nobody cares about that value. I went with (3) here as the smallest and most obvious change.

2025-07-24submodule: prevent overwriting .gitmodules on path reuseK Jayatheerth1-0/+27
Adding a submodule at a path that previously hosted another submodule (e.g., 'child') reuses the submodule name derived from the path. If the original submodule was only moved (e.g., to 'child_old') and not renamed, this silently overwrites its configuration in .gitmodules. This behavior loses user configuration and causes confusion when the original submodule is expected to remain intact. It assumes that the path-derived name is always safe to reuse, even though the name might still be in use elsewhere in the repository. Teach module_add() to check if the computed submodule name already exists in the repository's submodule config, and if so, refuse the operation unless the user explicitly renames the submodule or uses the --force option, which will automatically generate a unique name by appending a number (e.g., child1).

2025-07-23config: move Git config parsing into "environment.c"Patrick Steinhardt40-0/+40
In "config.c" we host both the business logic to read and write config files as well as the logic to parse specific Git-related variables. On the one hand this is mixing concerns, but even more importantly it means that we cannot easily remove the dependency on `the_repository` in our config parsing logic. Move the logic into "environment.c". This file is a grab bag of all kinds of global state already, so it is quite a good fit. Furthermore, it also hosts most of the global variables that we're parsing the config values into, making this an even better fit. Note that there is one hidden change: in `parse_fsync_components()` we use an `int` to iterate through `ARRAY_SIZE(fsync_component_names)`. But as -Wsign-compare warnings are enabled in this file this causes a compiler warning. The issue is fixed by using a `size_t` instead. This change allows us to drop the `USE_THE_REPOSITORY_VARIABLE` declaration. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-07-23config: drop `git_config_set_multivar()` wrapperPatrick Steinhardt3-13/+13
In 036876a1067 (config: hide functions using `the_repository` by default, 2024-08-13) we have moved around a bunch of functions in the config subsystem that depend on `the_repository`. Those function have been converted into mere wrappers around their equivalent function that takes in a repository as parameter, and the intent was that we'll eventually remove those wrappers to make the dependency on the global repository variable explicit at the callsite. Follow through with that intent and remove `git_config_set_multivar()`. All callsites are adjusted so that they use `repo_config_set_multivar(the_repository, ...)` instead. While some callsites might already have a repository available, this mechanical conversion is the exact same as the current situation and thus cannot cause any regression. Those sites should eventually be cleaned up in a later patch series. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
