Jakub Konka 359160c8b1 git: Add askpass delegate to git-commit handlers (#42239)
In my local setup, I always enforce git-commit signing with GPG/SSH
which automatically enforces `git commit -S` when committing. This
changeset will now show a modal to the user for them to specify the
passphrase (if any) so that they can unlock their private key for
signing when committing in Zed.

Ayush Chandekar e025ee6a11 git: Add base branch support to create_branch (#42151)
Closes [#41674](https://github.com/zed-industries/zed/issues/41674)

Description:
Creating a branch from a base requires switching to the base branch
first, then creating the new branch and checking out to it, which
requires multiple operations.

Add base_branch parameter to create_branch to allow a new branch from a
base branch in one operation which is synonymous to the command `git
switch -c <new-branch> <base-branch>`.

Below is the video after solving the issue: 

(`master` branch is the default branch here, and I create a branch
`new-branch-2` based off the `master` branch. I also show the error
which used to appear before the fix.)

Release Notes:

- Fixed the branch-picking error by replacing multiple sequential switch
operations with just one switch operation.

Alvaro ParkerandCole Miller e5660d25f1 git: Add git worktree picker (#38719)
Related discussions #26084 

Worktree creations are implemented similar to how branch creations are
handled on the branch picker (the user types a new name that's not on
the list and a new entry option appears to create a new branch with that
name).


https://github.com/user-attachments/assets/39e58983-740c-4a91-be88-57ef95aed85b

With this picker you have a few workflows: 

- Open the picker and type the name of a branch that's checked out on an
existing worktree:
    - Press enter to open the worktree on a new window
- Press ctrl-enter to open the worktree and replace the current window
- Open the picker and type the name of a new branch or an existing one
that's not checked out in another worktree:
- Press enter to create the worktree and open in a new window. If the
branch doesn't exists, we will create a new one based on the branch you
have currently checked out. If the branch does exists then we create a
worktree with that branch checked out.
- Press ctrl-enter to do everything on the previous point but instead,
replace the current window with the new worktre.
- Open the picker and type the name of a new branch or an existing one
that's not checked out in another worktree:
- If a default branch is detected on the repo, you can create a new
worktree based on that branch by pressing ctrl-enter or
ctrl-shift-enter. The first one will open a new window and the last one
will replace the current one.


Note: If you preffer to not use the system prompt for choosing a
directory, you can set `"use_system_path_prompts": false` in zed
settings.

Release Notes:

- Added git worktree picker to open a git worktree on a new window or
replace the current one
- Added git worktree creation action

Alvaro Parker db404fc2e3 git: Add diff view for stash entries (#38280)
Continues the work from #35927 to add a git diff view for stash entries.

[Screencast From 2025-09-17
19-46-01.webm](https://github.com/user-attachments/assets/ded33782-adef-4696-8e34-3665911c09c7)

Stash entries are [represented as
commits](https://git-scm.com/docs/git-stash#_discussion) except they
have up to 3 parents:

```
       .----W (this is the stash entry)
      /    /|
-----H----I |
           \|
            U
```

Where `H` is the `HEAD` commit, `I` is a commit that records the state
of the index, and `U` is another commit that records untracked files
(when using `git stash -u`).

Given this, I modified the existing commit view struct to allow loading
stash and commits entries with git sha identifier so that we can get a
similar git diff view for both of them.

The stash diff is generated by comparing the stash commit with its
parent (`<commit>^` or `H` in the diagram) which generates the same diff
as doing `git stash show -p <stash entry>`. This *can* be
counter-intuitive since a user may expect the comparison to be made
between the stash commit and the current commit (`HEAD`), but given that
the default behavior in git cli is to compare with the stash parent, I
went for that approach.

Hoping to get some feedback from a Zed team member to see if they agree
with this approach.

Release Notes:

- Add git diff view for stash entries
- Add toolbar on git diff view for stash entries
- Prompt before executing a destructive stash action on diff view
- Fix commit view for merge commits  (see #38289)

03f9cf4414 Represent relative paths using a dedicated, separator-agnostic type (#38744)
Closes https://github.com/zed-industries/zed/issues/38690
Closes #37353

### Background

On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.

Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.

### Solution

Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.

The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).

This PR continues work from #32821 by adding a stash entry picker for
pop/drop operations. Additionally, the stash pop action in the git panel
is now disabled when no stash entries exist, preventing error logs from
attempted pops on empty stashes.

Eric Cornelissen 1d72fa8e9e git: Add ability to pass --signoff (#29874)
This adds an option for `--signoff` to the git panel and commit modal.
It allows users to enable the [`--signoff`
flag](https://git-scm.com/docs/git-commit#Documentation/git-commit.txt-code--signoffcode)
when committing through Zed. The option is added to the context menu of
the commit button (following the style of the "Editor Controls").

To support this, the commit+amend experience was revamped (following the
ideas of [this
comment](https://github.com/zed-industries/zed/pull/29874#issuecomment-2950848000)).
Amending is now also a toggle in the commit button's dropdown menu. I've
kept some of the original experience such as the changed button text and
ability to cancel outside the context menu.

The tooltip of the commit buttons now also includes the flags that will
be used based on the amending and signoff status (which I couldn't
capture in screenshots unfortunately). So, by default the tooltip will
say `git commit` and if you toggle, e.g., amending on it will say `git
commit --amend`.

## Issue

The agent may run very slowly on projects that contain many or large
binary files not listed in `.gitignore`.


## Solution

Temporarily rewrite `.git/info/exludes` to ignore:
- Common binary files based on the extension
- Files larger than 2 MB

## Benchmark

I measure the time between sending an agent message in UI ("hitting
Enter") and actually sending it to an LLM. Ideally, it should be
instant. Numbers for a 7.7 GB Rust project with no .gitignore.

Filter                            | Time
----------------------------------|-----
No filter (= before this change)  | 62 s
Exclude common file types only    | 1.46 s
Exclude files >2MB only           | 1.16 s
Exclude both                      | 0.10 s


## Planned changes:

- [x] Exclude common binary file types
- [x] Exclude large files
- [ ] Track files added by agent so we could delete them (we can't rely
on git for that anymore)
- [ ] Don't block on waiting for a checkpoint to complete until we
really need it
- [ ] Only `git add` files that are about to change


Closes #ISSUE

Release Notes:

- Improved agent latency on repositories containing many files or large
files

Kirill Bulatov 16366cf9f2 Use anyhow more idiomatically (#31052)
https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.

The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.

The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.

* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

Release Notes:

- N/A

Cole Miller 7f5c874a38 git: Use the CLI for loading commit SHAs and details (#29351)
Since #28065 merged we've seen deadlocks inside iconv when opening Zed
in a repository containing many submodules. These calls to iconv happen
inside libgit2, in our implementations of the methods `head_sha`,
`merge_head_shas`, and `show` on `RealGitRepository`. This PR moves
those methods to use the git CLI instead, sidestepping the issue. For
the sake of efficiency, a new `revparse_batch` method is added that uses
`git cat-file` to resolve several ref names in one invocation. I
originally intended to make `show` operate in batch mode as well (or
instead), but I can't see a good way to do that with the git CLI; `git
show` always bails on the first ref that it can't resolve, and
`for-each-ref` doesn't support symbolic refs like `HEAD`.

Separately, I removed the calls to `show` in `MergeDetails::load`, going
back to only loading the SHAs of the various merge heads. Loading full
commit details was intended to support the inlays feature that ended up
being cut from #28065, and we can add it back in when we need it.

Release Notes:

- N/A
