2023-11-24orphan/unborn: add to the glossary and use them consistentlyJunio C Hamano
To orphan is a verb that denotes the act of getting on an unborn branch, and a few references to "orphan branch" in our documentation are misuses of the word. They caused end-user confusion, which was made even worse because we did not have the term defined in the glossary document. Add entries for "unborn" branch and "orphan" operation to the glossary, and adjust existing documentation accordingly. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-10-10doc/git-worktree: mention "refs/rewritten" as per-worktree refsPatrick Steinhardt
Some references are special in the context of worktrees as they are considered to be per-worktree instead of shared across all of the worktrees. Most importantly, this includes "refs/worktree/" that have explicitly been designed such that users can create per-woorktree refs. But there are also special references that have an associated meaning like "refs/bisect/", which is used to track state of git-bisect(1). These special per-worktree references are documented in git-worktree(1), but one instance is missing. In a9be29c9817 (sequencer: make refs generated by the `label` command worktree-local, 2018-04-25), we have converted "refs/rewritten/" to be a per-worktree reference as well. These references are used by our sequencer infrastructure to generate labels for rebased commits. So in order to allow for multiple concurrent rebases to happen in different worktrees, these references need to be tracked per worktree. We forgot to update our documentation to mention these new per-worktree references, which is fixed by this patch.

2023-05-17worktree add: extend DWIM to infer --orphanJacob Abel
Extend DWIM to try to infer `--orphan` when in an empty repository. i.e. a repository with an invalid/unborn HEAD, no local branches, and if `--guess-remote` is used then no remote branches. This behavior is equivalent to `git switch -c` or `git checkout -b` in an empty repository. Also warn the user (overriden with `-f`/`--force`) when they likely intend to checkout a remote branch to the worktree but have not yet fetched from the remote. i.e. when using `--guess-remote` and there is a remote but no local or remote refs.

2022-02-08Documentation: add extensions.worktreeConfig detailsDerrick Stolee
The extensions.worktreeConfig extension was added in 58b284a (worktree: add per-worktree config files, 2018-10-21) and was somewhat documented in Documentation/git-config.txt. However, the extensions.worktreeConfig value was not specified further in the list of possible config keys. The location of the config.worktree file is not specified, and there are some precautions that should be mentioned clearly, but are only mentioned in git-worktree.txt. Expand the documentation to help users discover the complexities of extensions.worktreeConfig by adding details and cross links in these locations (relative to Documentation/): - config/extensions.txt - git-config.txt - git-worktree.txt The updates focus on items such as * $GIT_DIR/config.worktree takes precedence over $GIT_COMMON_DIR/config. * The core.worktree and core.bare=true settings are incorrect to have in the common config file when extensions.worktreeConfig is enabled. * The sparse-checkout settings core.sparseCheckout[Cone] are recommended to be set in the worktree config. As documented in 11664196ac ("Revert "check_repository_format_gently(): refuse extensions for old repositories"", 2020-07-15), this extension must be considered regardless of the repository format version for historical reasons. A future change will update references to extensions.worktreeConfig within git-sparse-checkout.txt, but a behavior change is needed before making those updates.

2021-01-30worktree: teach `list` verbose modeRafael Silva
"git worktree list" annotates each worktree according to its state such as "prunable" or "locked", however it is not immediately obvious why these worktrees are being annotated. For prunable worktrees a reason is available that is returned by should_prune_worktree() and for locked worktrees a reason might be available provided by the user via `lock` command. Let's teach "git worktree list" a --verbose mode that outputs the reason why the worktrees are being annotated. The reason is a text that can take virtually any size and appending the text on the default columned format will make it difficult to extend the command with other annotations and not fit nicely on the screen. In order to address this shortcoming the annotation is then moved to the next line indented followed by the reason If the reason is not available the annotation stays on the same line as the worktree itself. The output of "git worktree list" with verbose becomes like so: $ git worktree list --verbose ... /path/to/locked-no-reason acb124 [branch-a] locked /path/to/locked-with-reason acc125 [branch-b] locked: worktree with a locked reason /path/to/prunable-reason ace127 [branch-d] prunable: gitdir file points to non-existent location ...

2021-01-30worktree: teach `list` to annotate prunable worktreeRafael Silva
The "git worktree list" command shows the absolute path to the worktree, the commit that is checked out, the name of the branch, and a "locked" annotation if the worktree is locked, however, it does not indicate whether the worktree is prunable. The "prune" command will remove a worktree if it is prunable unless `--dry-run` option is specified. This could lead to a worktree being removed without the user realizing before it is too late, in case the user forgets to pass --dry-run for instance. If the "list" command shows which worktree is prunable, the user could verify before running "git worktree prune" and hopefully prevents the working tree to be removed "accidentally" on the worse case scenario. Let's teach "git worktree list" to show when a worktree is a prunable candidate for both default and porcelain format. In the default format a "prunable" text is appended: $ git worktree list /path/to/main aba123 [main] /path/to/linked 123abc [branch-a] /path/to/prunable ace127 (detached HEAD) prunable In the --porcelain format a prunable label is added followed by its reason: $ git worktree list --porcelain ... worktree /path/to/prunable HEAD abc1234abc1234abc1234abc1234abc1234abc12 detached prunable gitdir file points to non-existent location ...

2020-12-21worktree: teach `repair` to fix multi-directional breakageEric Sunshine
`git worktree repair` knows how to repair the two-way links between the repository and a worktree as long as a link in one or the other direction is sound. For instance, if a linked worktree is moved (without using `git worktree move`), repair is possible because the worktree still knows the location of the repository even though the repository no longer knows where the worktree is. Similarly, if the repository is moved, repair is possible since the repository still knows the locations of the worktrees even though the worktrees no longer know where the repository is. However, if both the repository and the worktrees are moved, then links are severed in both directions, and no repair is possible. This is the case even when the new worktree locations are specified as arguments to `git worktree repair`. The reason for this limitation is twofold. First, when `repair` consults the worktree's gitfile (/path/to/worktree/.git) to determine the corresponding <repo>/worktrees/<id>/gitdir file to fix, <repo> is the old path to the repository, thus it is unable to fix the `gitdir` file at its new location since it doesn't know where it is. Second, when `repair` consults <repo>/worktrees/<id>/gitdir to find the location of the worktree's gitfile (/path/to/worktree/.git), the path recorded in `gitdir` is the old location of the worktree's gitfile, thus it is unable to repair the gitfile since it doesn't know where it is. Fix these shortcomings by teaching `repair` to attempt to infer the new location of the <repo>/worktrees/<id>/gitdir file when the location recorded in the worktree's gitfile has become stale but the file is otherwise well-formed. The inference is intentionally simple-minded. For each worktree path specified as an argument, `git worktree repair` manually reads the ".git" gitfile at that location and, if it is well-formed, extracts the <id>. It then searches for a corresponding <id> in <repo>/worktrees/ and, if found, concludes that there is a reasonable match and updates <repo>/worktrees/<id>/gitdir to point at the specified worktree path. In order for <repo> to be known, `git worktree repair` must be run in the main worktree or bare repository. `git worktree repair` first attempts to repair each incoming /path/to/worktree/.git gitfile to point at the repository, and then attempts to repair outgoing <repo>/worktrees/<id>/gitdir files to point at the worktrees. This sequence was chosen arbitrarily when originally implemented since the order of fixes is immaterial as long as one side of the two-way link between the repository and a worktree is sound. However, for this new repair technique to work, the order must be reversed. This is because the new inference mechanism, when it is successful, allows the outgoing <repo>/worktrees/<id>/gitdir file to be repaired, thus fixing one side of the two-way link. Once that side is fixed, the other side can be fixed by the existing repair mechanism, hence the order of repairs is now significant. Two safeguards are employed to avoid hijacking a worktree from a different repository if the user accidentally specifies a foreign worktree as an argument. The first, as described above, is that it requires an <id> match between the repository and the worktree. That itself is not foolproof for preventing hijack, so the second safeguard is that the inference will only kick in if the worktree's /path/to/worktree/.git gitfile does not point at a repository.

2020-09-07git-worktree.txt: discuss branch-based vs. throwaway worktreesEric Sunshine
By default, `git worktree add` creates a new worktree associated with a particular branch (which may have been created automatically if not specified explicitly on the command-line). It is also convenient to create throwaway worktrees not associated with any branch, which can be handy when making experimental changes or doing testing. However, the latter use-case may not be obvious to newcomers since the high-level description of worktrees talks only about checking out "more than one branch at a time". Therefore, enhance the description to to discuss both use-cases. A secondary goal of highlighting the distinction between branch-based and throwaway worktrees is to help newcomers understand that the simplest form `git worktree add <path>` automatically creates a new branch. Stating this early in the description, may help newcomers avoid creating branches without realizing they are doing so, and later wondering why `git branch --list` shows branches the user did not intentionally create.

2020-08-31worktree: teach "repair" to fix outgoing links to worktreesEric Sunshine
The .git/worktrees/<id>/gitdir file points at the location of a linked worktree's .git file. Its content must be of the form /path/to/worktree/.git (from which the location of the worktree itself can be derived by stripping the "/.git" suffix). If the gitdir file is deleted or becomes corrupted or outdated, then Git will be unable to find the linked worktree. An easy way for the gitdir file to become outdated is for the user to move the worktree manually (without using "git worktree move"). Although it is possible to manually update the gitdir file to reflect the new linked worktree location, doing so requires a level of knowledge about worktree internals beyond what a user should be expected to know offhand. Therefore, teach "git worktree repair" how to repair broken or outdated .git/worktrees/<id>/gitdir files automatically. (For this to work, the command must either be invoked from within the worktree whose gitdir file requires repair, or from within the main or any linked worktree by providing the path of the broken worktree as an argument to "git worktree repair".)

If a worktree's .git file is deleted or becomes corrupted or outdated, then the linked worktree won't know how to find the repository or any of its own administrative files (such as 'index', 'HEAD', etc.). An easy way for the .git file to become outdated is for the user to move the main worktree or bare repository. Although it is possible to manually update each linked worktree's .git file to reflect the new repository location, doing so requires a level of knowledge about worktree internals beyond what a user should be expected to know offhand. Therefore, teach "git worktree repair" how to repair broken or outdated worktree .git files automatically.

2020-08-04git-worktree.txt: make start of new sentence more obviousEric Sunshine
When reading the rendered description of `add`, it's easy to trip over and miss the end of one sentence and the start of the next, making it seem as if they are part of the same statement, separated only by a dash: ... specific files such as HEAD, index, etc. - may also be specified as <commit-ish>; it is synonymous with... This can be particularly confusing since the thoughts expressed by the two sentences are unrelated. Reduce the likelihood of confusion by making it obvious that the two sentences are distinct.

2020-08-04git-worktree.txt: consistently use term "working tree"Eric Sunshine
As originally composed, git-worktree.txt employed a mix of "worktree" and "working tree" which was inconsistent and potentially confusing to readers. bc483285b7 (Documentation/git-worktree: consistently use term "linked working tree", 2015-07-20) undertook the task of employing the term "working tree" consistently throughout the document and avoiding "worktree" altogether for descriptive text.

2020-06-10worktree: make "move" refuse to move atop missing registered worktreeEric Sunshine
"git worktree add" takes special care to avoid creating a new worktree at a location already registered to an existing worktree even if that worktree is missing (which can happen, for instance, if the worktree resides on removable media). "git worktree move", however, is not so careful when validating the destination location and will happily move the source worktree atop the location of a missing worktree. This leads to the anomalous situation of multiple worktrees being associated with the same path, which is expressly forbidden by design. For example: $ git clone foo.git $ cd foo $ git worktree add ../bar $ git worktree add ../baz $ rm -rf ../bar $ git worktree move ../baz ../bar $ git worktree list .../foo beefd00f [master] .../bar beefd00f [bar] .../bar beefd00f [baz] $ git worktree remove ../bar fatal: validation failed, cannot remove working tree: '.../bar' does not point back to '.git/worktrees/bar' Fix this shortcoming by enhancing "git worktree move" to perform the same additional validation of the destination directory as done by "git worktree add". While at it, add a test to verify that "git worktree move" won't move a worktree atop an existing (non-worktree) path -- a restriction which has always been in place but was never tested.

2018-10-22refs: new ref types to make per-worktree refs visible to all worktreesNguyễn Thái Ngọc Duy
One of the problems with multiple worktree is accessing per-worktree refs of one worktree from another worktree. This was sort of solved by multiple ref store, where the code can open the ref store of another worktree and has access to the ref space of that worktree. The problem with this is reporting. "HEAD" in another ref space is also called "HEAD" like in the current ref space. In order to differentiate them, all the code must somehow carry the ref store around and print something like "HEAD from this ref store". But that is not feasible (or possible with a _lot_ of work). With the current design, we pass a reference around as a string (so called "refname"). Extending this design to pass a string _and_ a ref store is a nightmare, especially when handling extended SHA-1 syntax. So we do it another way. Instead of entering a separate ref space, we make refs from other worktrees available in the current ref space. So "HEAD" is always HEAD of the current worktree, but then we can have "worktrees/blah/HEAD" to denote HEAD from a worktree named "blah". This syntax coincidentally matches the underlying directory structure which makes implementation a bit easier. The main worktree has to be treated specially because well... it's special from the beginning. So HEAD from the main worktree is acccessible via the name "main-worktree/HEAD" instead of "worktrees/main/HEAD" because "main" could be just another secondary worktree. This patch also makes it possible to specify refs from one worktree in another one, e.g. git log worktrees/foo/HEAD Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-10-22worktree: add per-worktree config filesNguyễn Thái Ngọc Duy
A new repo extension is added, worktreeConfig. When it is present: - Repository config reading by default includes $GIT_DIR/config _and_ $GIT_DIR/config.worktree. "config" file remains shared in multiple worktree setup. - The special treatment for core.bare and core.worktree, to stay effective only in main worktree, is gone. These config settings are supposed to be in config.worktree. This extension is most useful in multiple worktree setup because you now have an option to store per-worktree config (which is either .git/config.worktree for main worktree, or .git/worktrees/xx/config.worktree for linked ones). This extension can be used in single worktree mode, even though it's pretty much useless (but this can happen after you remove all linked worktrees and move back to single worktree). "git config" reads from both "config" and "config.worktree" by default (i.e. without either --user, --file...) when this extension is present. Default writes still go to "config", not "config.worktree". A new option --worktree is added for that (*). Since a new repo extension is introduced, existing git binaries should refuse to access to the repo (both from main and linked worktrees). So they will not misread the config file (i.e. skip the config.worktree part). They may still accidentally write to the config file anyway if they use with "git config --file <path>". This design places a bet on the assumption that the majority of config variables are shared so it is the default mode. A safer move would be default writes go to per-worktree file, so that accidental changes are isolated. (*) "git config --worktree" points back to "config" file when this extension is not present and there is only one worktree so that it works in any both single and multiple worktree setups.

2018-10-06Add a place for (not) sharing stuff between worktreesNguyễn Thái Ngọc Duy
When multiple worktrees are used, we need rules to determine if something belongs to one worktree or all of them. Instead of keeping adding rules when new stuff comes (*), have a generic rule: - Inside $GIT_DIR, which is per-worktree by default, add $GIT_DIR/common which is always shared. New features that want to share stuff should put stuff under this directory. - Inside refs/, which is shared by default except refs/bisect, add refs/worktree/ which is per-worktree. We may eventually move refs/bisect to this new location and remove the exception in refs code. (*) And it may also include stuff from external commands which will have no way to modify common/per-worktree rules.

2018-08-30worktree: teach 'add' to respect --force for registered but missing pathEric Sunshine
For safety, "git worktree add <path>" will refuse to add a new worktree at <path> if <path> is already associated with a worktree entry, even if <path> is missing (for instance, has been deleted or resides on non-mounted removable media or network share). The typical way to re-create a worktree at <path> in such a situation is either to prune all "broken" entries ("git worktree prune") or to selectively remove the worktree entry manually ("git worktree remove <path>"). However, neither of these approaches ("prune" nor "remove") is especially convenient, and they may be unsuitable for scripting when a tool merely wants to re-use a worktree if it exists or create it from scratch if it doesn't (much as a tool might use "mkdir -p" to re-use or create a directory). Therefore, teach 'add' to respect --force as a convenient way to re-use a path already associated with a worktree entry if the path is non-existent. For a locked worktree, require --force to be specified twice. Signed-off-by: Eric Sunshine <sunshine@sunshineco.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
