Here's some backstory:
* on macOS, @cole-miller and I noticed that since roughly Oct 2025, due
to some changes to latest macOS Tahoe, for any spawned child process we
needed to reset Mach exception ports
(https://github.com/zed-industries/zed/issues/36754 +
6e8f2d2ebe)
* the changes in that PR achieve that via `pre_exec` hook on
`std::process::Command` which then abandons `posix_spawn` syscall for
`fork` + `execve` dance on macOS (we tracked it down in Rust's std
implementation)
* as it turns out, `fork` + `execve` is pretty expensive on macOS
(apparently way more so than on other OSes like Linux) and `fork` takes
a process-wide lock on the allocator which is bad
* however, since we wanna reset exception ports on the child, the only
official way supported by Rust's std is to use `pre_exec` hook
* posix_spawn on macOS exposes this tho via a macOS specific extension
to that syscall `posix_spawnattr_setexceptionports_np` but there is no
way to use that via any standard interfaces in `std::process::Command`
* thus, it seemed like a good idea to instead create our own custom
Command wrapper that on non-macOS hosts is a zero-cost wrapper of
`smol::process::Command`, while on macOS we reimplement the minimum to
achieve `smol::process::Command` with `posix_spawn` under-the-hood
Notably, this changeset improves git-blame in very large repos
significantly.
Release Notes:
- Fixed performance spawning child processes on macOS by always forcing
`posix_spawn` no matter what.

Release Notes:
- N/A (nightly only)
Git commands can fail when staging or unstaging a very large number of
files because each file path is passed as a separate CLI argument. Once
the argument list grows beyond the OS limit, git errors with Argument
list too long (os error 7).
Since git 2.26, pathspecs can be read from stdin, which lets us avoid
passing thousands of paths as arguments and bypass this limitation.
I looked for existing issues related to this but couldn’t find any.
Repro:
- Clone rust-lang repo
- Delete root tests folder
- Try to stage or unstage (40,000+ files)
- Git fails with Argument list too long (os error 7)
Release Notes:
- Fixed an issue where stage/unstage could fail when operating on a very
large number of files
GitHub's commit API endpoint is rate limited to 60 requests/hour for
unauthenticated users. This causes avatar loading to fail after toggling
blame a few times.
This PR uses GitHub's CDN avatar endpoint
`https://avatars.githubusercontent.com/u/e?email={email}&s=128` instead,
which doesn't count against API rate limits. The author email is already
available from local git data (blame output), so
no API calls are needed.
- When author email is available, constructs the CDN URL directly (zero
API calls)
- Falls back to existing API-based behavior when email is unavailable
- Adds unit tests for URL construction
Closes#47590
## Test plan
- [x] `./script/clippy` passes
- [x] `cargo test -p git_hosting_providers` passes (89 tests including 3
new ones i added)
- [ ] Manual test: Open a file, toggle git blame, verify avatars load
without hitting rate limits
Release Notes:
- Fixed GitHub avatar rate limiting in git blame by using CDN endpoint
instead of API calls (#47590)
Basically just replaced `SharedString::new("` with
`SharedShring::new_static("` which removes the allocation to `Arc<str>`.
Unfortunately this can't be enforced at compile time without trait
specialization which is only available on nightly. You could assert that
`TypeId`'s differ, but `TypeId` only exists at runtime.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
Closes#26866
### Summary
Adds a git graph to Zed, accessible via the `git_graph::Open` action if
a project has an active repository. There's still more to do, but this
is a solid foundation to expand upon. The code structure is in line with
Zed's codebase and shouldn't require architectural changes to add
missing features.
The git graph can be opened via the command palette (`git graph: open`)
or by binding a key to `git_graph::Open`. It's available when the
project has an active git repository.
### Architecture
Similar to the Debugger, the git graph is split between a data layer and
a view/UI layer. When the view layer is rendering, it queries the data
layer for its active state. This setup allows the data layer to lazily
request graph data (only when needed for rendering), abstracts collab
from the view layer, allows most of the data loading to happen on a
background thread, and makes caching easy to implement.
#### Graph Loading
The graph data is loaded in two phases:
1. `Repository::graph_data()` streams commit structure (SHA, parents,
refs) in chunks of 1000 via `git log`
2. `CommitDataReader` lazily fetches full commit details (author,
timestamp, subject) on-demand using a persistent `git cat-file --batch`
process
This two-phase approach makes the initial loading of the graph as fast
as possible, because `git log` takes significantly longer when all the
needed graph data is queried through it. Zed then lazily loads commits
in the user's viewport through `cat-file --batch`. This makes scrolling
to any place in the graph extremely snappy and benefits the
collaborative architecture by only fetching data needed to render the
graph. It also allows Zed to share commit data between different graph
visualizations (e.g., date order vs. topological order).
#### Performance
Tested on both the Zed and LLVM repositories with good performance in
both cases. The two-phase loading approach and lazy fetching keep the UI
responsive even with large commit histories.
#### Testing
I added property testing that builds randomized commit graphs and
verifies that the graph is constructed correctly. This also works as an
integration test and will be expanded in the future to test collab graph
visualization, graph filtering, commit actions, etc.
### New Crate
- `git_graph` (GPL-licensed) — contains UI and graph computation logic
### Not Yet Implemented
- Remote repository support (collab)
- Filtering by branch
- Commit actions (checkout, cherry-pick, etc.)
- Search
- Open commit view for selected commit
- Resizable columns
- Column filtering

This happens when a user's default branch has different remote and local
versions on their system. Because we would get a diff using just a
branch name without including it's remote name as well
This is a better default because it's far less confusing from a user's
perspective to debug what's going on.
Release Notes:
- git: Fix BranchDiff showing incorrect diffs when default local branch
is out of sync with the remote default branch
Also improves the commit view to use the same status-based buffer header
visual overrides as the project diff as a driveby.
Fixes https://github.com/zed-industries/zed/issues/45735

Closes#26424
Supersedes #35328
Originally, `git::blame` uses its own `ParsedCommitMessage` as the
source for the commit information, including the PR section. This
changes unifies this with `git::repository` and `git_ui::git_panel` by
moving this and some other commit-related structs to `git::commit`
instead, and making both `git_ui::blame_ui` and `git_ui::git_panel` pull
their information from these structs.
Release notes :
- (Let's Git Together) Fixed the commit tooltip in the git panel not
showing information like avatars.

Fix git hook hang when using with `prek`. Can see
[comments](https://github.com/zed-industries/zed/issues/44057#issuecomment-3606837089),
this is easy test, should using release build, debug build sometimes not
hang.
The issue existing long time, see issue #37293 , and then in commit

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.

Release Notes:

askpass modal
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.)

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

Previously, staging a large file in the git panel would block the UI
items until that operation finished. This is due to the fact that
staging is a git op that is locked globally by git (per repo) meaning
only one op that is modifying the git index can run at any one time. In
order to make the UI snappy while letting any pending git staging jobs
to finish in the background, we track their progress via `PendingOps`
indexed by git entry path. We have already had a concept of pending
operations however they existed at the UI layer in the `GitPanel`
abstraction. This PR moves and augments `PendingOps` into the model
`Repository` in `git_store` which seems like a more natural place for
tracking running git jobs/operations. Thanks to this, pending ops are
now stored in a `SumTree` indexed by git entry path part of the
`Repository` snapshot, which makes for efficient access from the UI.
Release Notes:
- Improved UI responsiveness when staging/unstaging large files in the
git panel
- Adds a new action `git::PullRebase` which adds `--rebase` in the final
command invoked by existing Git-Pull implementation.
- Includes the new action in "Fetch/Push" button in the Git Panel
(screenshot below)
- Adds key-binding for `git::PullRebase` in all three platforms,
following the existing key-binding patterns (`ctrl-g shift-down`)
- Update git docs to include the new action.
Sidenote: This is my first ever OSS contribution

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

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)
We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.
