For inverted diff APIs like `hunks_intersecting_base_text_range`, we
need a snapshot of the main buffer to use as context to compare hunk
anchors, convert anchors to points, etc. Previously, we were always
using a snapshot of the main buffer at the time when the diff was
calculated. This worked well for the hunks of the primary `BufferDiff`,
but it's not valid when the diff also has a secondary set of hunks,
because those hunks are recalculated on their own schedule--so it's
possible for the hunks of the secondary diff to contain anchors that are
newer than the original buffer snapshot that was taken at the time the
primary diff hunks were last calculated. This caused a panic when using
these anchors with the original buffer snapshot.
This PR fixes the issue by using the same approach for inverted diffs as
for non-inverted diffs at the multibuffer level: we take a snapshot of
the main buffer at the time when we snapshot the diff state (including
the diff itself), guaranteeing that that snapshot will be new enough to
resolve all the anchors included in both the primary diff and the
secondary diff.
Closes ZED-54J
Release Notes:
- Fixed a panic that could occur when using the branch diff in split
view mode.

This PR removes onboarding modals for features that were announced, at
this point, a long time ago: Git v1, Debugger, and Agent Panel v1. This

left the ACP and Claude Code ones, though; they were the two more recent
ones, but we should be able to remove them soon enough, too.

This change improves performance of project diff in that:
* scrolling in split view for very large diffs (think chromium repo with
`git reset HEAD~1000`) is now very smooth on macOS and fairly smooth on
Linux
* switching from split to unified is very smooth on macOS, and fairly
smooth on Linux
There still remains the case of (severe) hangs when switching from
unified to split however, but it will be addressed in a follow-up PR.
Anyhow, here's the screenshot of the Instruments.app capture of opening
chromium repo in Zed in split view, scrolling a little, moving to
unified, scrolling some more, and moving back to split. Prior to this
change, split -> unified would cause a severe hang, whereas now it's a
hang and thus feels much smoother already (without Instruments profiling
is barely visible). Unified -> split severe hangs are still there but
don't last as long.

Searching (and related vim stuff like `*`/`n`/`N`) now work in the LHS
of a
split diff.
Also fixes the bug with indent guides being visible through the spacer
checkerboard pattern.
Release Notes:
- N/A
Currently we always compute breadcrumbs and sticky headers on every
editor paint which is not cheap to do especially in bigger files, moving
this off to be computed on event handling where they change and then
caching them can save serveral milliseconds per render in bigger files.
This also puts matching brackets refreshing and document highlights on a
background task, as this tends to block the main task for prolonged time
as well.

Closes#48195
Filter out `remote_info` when viewing stashes by adding `.filter(|_|
self.stash.is_none())`.
Release Notes:
- Fixed "View on GitHub" button incorrectly appearing when viewing
stashes
The indent guide computation was using visible list indices directly to
access entries, instead of mapping through `logical_indices` first. This
caused incorrect depths to be read from hidden entries when a folder was
collapsed, resulting in stray vertical lines extending to unrelated folders.
Closes#48189
Release Notes:
- Fixed a visual bug in the Git Panel where collapsing a folder in tree
view would cause indent guide lines to incorrectly extend to unrelated
folders below it.
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)
This branch:
1. teaches `--diff `command line option to to recurse into folders if
provided.
2. Adds a `MultiDiffView` that shows _all_ changed files in a single,
scrollable view.
This is necessary to provide a smooth user experience for `jj` and Zed
users who wish to use Zed as their jj difftool.
I'm not fully sure how this change interacts with
https://github.com/zed-industries/zed/pull/44936, or what plans y'all
have in mind.
Here's a screenshot of the resulting behavior:

I setup zed to handle jj diffs by adding the following to my jj config:
```toml
[aliases]
zdiff = ["diff", "--tool", "zed"]
[merge-tools.zed]
program = "/Users/dbarsky/Developer/zed/target/debug/cli"
# omit diff-invocation-mode to keep the default (JJ passes two dirs)
diff-args = [
"--zed", "/Users/dbarsky/Developer/zed/target/debug/zed",
"--wait",
"--new",
"--diff",
"$left",
"$right",
]
```
Release Notes:
- `--diff`, if provided with folders instead of files, will recurse into
those directories.
- Added a `MultiDiffView`, which will show all changed files within a
single, scrollable view.
**AI Disclosure**: Pretty much all of this code was written using Codex
with GPT-5.1-Codex. I edited by hand and tested this.

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.

When working in a workspace with multiple repositories, the git panel
provides a repository picker to switch between them. However, there was
no visual indication of which repositories have uncommitted changes:
users had to either select each repository individually or check the
project panel where modified directories are highlighted.
This change adds git status icons to the repository picker, allowing
users to see at a glance which repositories contain changes (modified,
added, deleted, or conflicted files). The icons use the same visual
language already established for file status throughout the git panel.
Additionally, the repository picker now matches the branch picker's
styling for visual consistency:
- Added "Repositories" header
- Aligned popover width and positioning
- Added scrollbar
- Added check icon next to currently selected repo
- Added selected branch under repo list item
- Sort by display name is now case insensitive

The rate limiter's semaphore guard was being held for the entire
duration of a turn, including during tool execution. This caused
deadlocks when subagents tried to acquire permits while parent requests
were waiting for them to complete.
## The Problem
In `run_turn_internal`, the stream (which contains the `RateLimitGuard`
holding the semaphore permit) was kept alive throughout the entire loop
iteration - including during **tool execution**:
1. Parent request acquires permit
2. Parent starts streaming, consumes response
3. Parent starts executing tools (subagents)
4. **Stream/guard still held** while tools execute
5. Subagents try to acquire permits → blocked because parent still holds
permit
6. Deadlock if all permits are held by parents waiting for subagent
children
## The Fix
Two changes were made:
1. **Drop the stream early**: Added an explicit `drop(events)` after the
stream is fully consumed but before tool execution begins. This releases
the rate limit permit so subagents can acquire it.
2. **Removed the `bypass_rate_limit` workaround**: Since the root cause
is now fixed, the bypass mechanism is no longer needed.
Note: no release notes because subagents are still feature-flagged, and
this rate limiting change isn't actually observable without them.

This PR improves the performance of the `CopyButton` component by
tracking the copied state locally through a `CopyButtonState` struct
instead of making an OS call every time the component re-renders. Also
pushing a slight improvement here by resetting the state after two
seconds so as to make the check mark go away after you clicked to copy.
Release Notes:
- N/A
## Problem
When subagents use the `edit_file` tool, it creates an `EditAgent` that
makes its own model request to get the edit instructions. These "nested"
requests compete with the parent subagent conversation requests for rate
limiter permits.
The rate limiter uses a semaphore with a limit of 4 concurrent requests
per model instance. When multiple subagents run in parallel:
1. 3 subagents each hold 1 permit for their ongoing conversation streams
(3 permits used)
2. When all 3 try to use `edit_file` simultaneously, their edit agents
need permits too
3. Only 1 edit agent can get the 4th permit; the other 2 block waiting
4. The blocked edit agents can't complete, so their parent subagent
conversations can't complete
5. The parent conversations hold their permits, so the blocked edit
agents stay blocked
6. **Deadlock**
## Solution
Added a `bypass_rate_limit` field to `LanguageModelRequest`. When set to
`true`, the request skips the rate limiter semaphore entirely. The
`EditAgent` sets this flag because its requests are already "part of" a
rate-limited parent request.
(No release notes because subagents are still feature-flagged.)
