This PR reworks the (still feature-gated) side-by-side diff view to use
a different approach to representing the multibuffers on the left- and
right-hand sides.
Previously, these two multibuffers used identical sets of buffers and
excerpts, and were made to behave differently by adding a new knob to
the multibuffer controlling how diffs are displayed. Specifically, the
left-hand side multibuffer would filter out the added range of each hunk
from the excerpts using a new `FilteredInsertedHunk` diff transform, and
the right-hand side would simply not show the deleted sides of expanded
hunks. This approach has some problems:
- Line numbers, and actions that navigate by line number, behaved
incorrectly for the left-hand side.
- Syntax highlighting and other features that use the buffer syntax tree
also behaved incorrectly for the left-hand side.
In this PR, we've switched to using independent buffers to build the
left-hand side. These buffers are constructed using the base texts for
the corresponding diffs, and their lifecycle is managed by `BufferDiff`.
The red "deleted" regions on the left-hand side are represented by
`BufferContent` diff transforms, not `DeletedHunk` transforms. This
means each excerpt on the left represents a contiguous slice of a single
buffer, which fixes the above issues by construction.
The tradeoff with this new approach is that we now have to manually
synchronize excerpt ranges from the right side to the left, which we do
using `BufferDiffSnapshot::row_to_base_text_row`.

Closes https://github.com/zed-industries/zed/issues/45630
Remote host location alone is not enough to distinguish between remote
worktrees: different remote projects open in different windows will have
the same remote host location and _will_ have the same `WorktreeId`.
Thus, require an associated `WorktreeStore` with all
`WorktreeId`-related trust questions, and store those IDs based on the
store key.
Release Notes:
- Fixed worktree trust handling of multiple projects on the same remote
host
Draft as a base for continuing the discussion in #8008 : adds a
`SplitOperation` enum to support bindings like `["pane::SplitLeft",
{"operation": "Clear"}]`
To be discussed @MrSubidubi and others:
- Naming: Generally not happy with names yet and specifically `Empty` is
unclear, e.g., what does this mean for terminal panes? Added placeholder
code to split without cloning, but unsure what users would expect in
this case.
- ~~I removed `SplitAndMoveXyz` actions but I guess we should keep them
for backwards compatibility?~~
- May have missed details in the move implementation. Will check the
code again for opportunities to refactor more code after we agree on the
approach.
- ~~Tests should go to `crates/collab/src/tests/integration_tests.rs`?~~
Closes#8008
Release Notes:
- Add `pane::Split` mode (`{ClonePane,EmptyPane,MovePane}`) to allow
creating an empty buffer.

Follow-up of https://github.com/zed-industries/zed/pull/44887
This fixes remote server builds.
Additionally:
* slightly rewords workspace trust text in the security modal
* eagerly ask for worktree trust on open
Release Notes:
- N/A
Closes https://github.com/zed-industries/zed/issues/12589
Forces Zed to require user permissions before running any basic
potentially dangerous actions: parsing and synchronizing
`.zed/settings.json`, downloading and spawning any language and MCP
servers (includes `prettier` and `copilot` instances) and all
`NodeRuntime` interactions.
There are more we can add later, among the ideas: DAP downloads on
debugger start, Python virtual environment, etc.
By default, Zed starts in restricted mode and shows a `! Restricted
Mode` in the title bar, no aforementioned actions are executed.
Clicking it or calling `workspace::ToggleWorktreeSecurity` command will
bring a modal to trust worktrees or dismiss the modal:
<img width="1341" height="475" alt="1"
src="https://github.com/user-attachments/assets/4fabe63a-6494-42c7-b0ea-606abb1c0c20"
/>
Agent Panel shows a message too:
<img width="644" height="106" alt="2"
src="https://github.com/user-attachments/assets/0a4554bc-1f1e-455b-b97d-244d7d6a3259"
/>
This works on local, SSH and WSL remote projects, trusted worktrees are
persisted between Zed restarts.
There's a way to clear all persisted trust with
`workspace::ClearTrustedWorktrees`, this will restart Zed.
This mechanism can be turned off with settings:
```jsonc
"session": {
"trust_all_worktrees": true
}
```
in this mode, all worktrees will be trusted by default, allowing all
actions, but no auto trust will be persisted: hence, when the setting is
changed back, auto trusted worktrees will require another trust
confirmation.
This settings switch was added to the onboarding view also.
Release Notes:
- Introduced worktree trust mechanism, can be turned off with
`"session": { "trust_all_worktrees": true }`

The test `test_collaborating_with_completion` has a latent race
condition that hasn't manifested on CI yet but could cause hangs with
certain task orderings.
## The Bug
Commit `fd1494c31a` set up LSP request handlers AFTER typing the trigger
character:
```rust
// Type trigger first - spawns async tasks to send completion request
editor_b.update_in(cx_b, |editor, window, cx| {
editor.handle_input(".", window, cx);
});
// THEN set up handlers (race condition!)
fake_language_server
.set_request_handler::<lsp::request::Completion, _, _>(...)
.next().await.unwrap(); // Waits for handler to receive a request
```
Whether this works depends on task scheduling order, which varies by
seed. If the completion request is processed before the handler is
registered, the request goes to `on_unhandled_notification` which claims
to handle it but sends no response, causing a hang.
## Changes
- Move handler setup BEFORE typing the trigger character
- Make `TestDispatcher::spawn_realtime` panic to prevent future
non-determinism from real OS threads
- Add `execution_hash()` and `execution_count()` to TestDispatcher for
debugging
- Add `DEBUG_SCHEDULER=1` logging for task execution tracing
- Document the investigation in `situation.md`

This PR removes the database schema migrations from the repo, as these
are now managed by Cloud.
There's a new `20251208000000_test_schema.sql` "migration" that we use

The registration ID responsible for generating each diagnostic is now
tracked. This allows us to replace only the diagnostics from the same
registration ID when a pull diagnostics report is applied.
Additionally, various deficiencies in our support for pull diagnostics
have been fixed:
- Document pulls are issued for all open buffers, not just the edited
one. A shorter debounce is used for the edited buffer. Workspace
diagnostics are also now ignored for open buffers.
- Tracking of `lastResultId` is improved.
- Stored pull diagnostics are discarded when the corresponding buffer is
closed.
Release Notes:
- Improved compatibility with language servers that use the "pull
diagnostics" feature of Language Server Protocol.

We'll now add panels to the workspace as soon as they're ready rather
than waiting for all the rest to complete. We should strive to make all
panels fast, but given that their load tasks are fallible and do IO,
this approach seems more resilient.
Additionally, we'll now start loading the agent panel at the same time
as the rest.
Release Notes:
- workspace: Add panels as soon as they are ready
We now run git pre-commit hooks before we commit. This ensures we don't
run into timeout issues with askpass delegate and report invalid error
to the user.

- Fixed long running pre-commit hooks causing committing from Zed to

Part One for Resolving #10910
### Summary
Typing prefix (partial keybinding) will behave like Vim. No timeout
until you either finish the sequence or hit Escape, while ambiguous
sequences still auto-resolve after 1s.
### Description
This follow-up tweaks the which-key system first part groundwork so our
timeout behavior matches Vim’s expectations. Then we can implement the
UI part in the next step (reference latest comments in
https://github.com/zed-industries/zed/pull/34798)
- `DispatchResult` now reports when the current keystrokes are already a
complete binding in the active context stack (`pending_has_binding`). We
only start the 1s flush timer in that case. Pure prefixes or sequences
that only match in other contexts—stay pending indefinitely, so
leader-style combos like `space f g` no longer evaporate after a second.
- `Window::dispatch_key_event` cancels any prior timer before scheduling
a new one and only spawns the background flush task when
`pending_has_binding` is true. If there’s no matching binding, we keep
the pending keystrokes and rely on an explicit Escape or more typing to
resolve them.
Release Notes:
- Fixed multi-stroke keybindings so only ambiguous prefixes auto-trigger
after 1 s; unmatched prefixes now stay pending until canceled, matching
Vim-style leader behavior.
This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

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.)

Adds support for opening and displaying images in remote projects. The
server streams image data to the client in chunks, where the client then
reconstructs the image and displays it. This change includes:
- Adding `image` crate as a dependency for remote_server
- Implementing `ImageStore` for remote access
- Creating proto definitions for image-related messages
- Adding handlers for creating images for peers
- Computing image metadata from bytes instead of reading from disk for
remote images
Closes#20430Closes#39104Closes#40445
Release Notes:
- Added support for image preview in remote sessions.
- Fixed#39104
