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
Follow-up of https://github.com/zed-industries/zed/pull/44887
Trims the worktree trust mechanism to the actual `worktree`s, so now
"global", workspace-level things like `prettier`, `NodeRuntime`,
`copilot` and global MCP servers are considered as "trusted" a priori.
In the future, a separate mechanism for those will be considered and
added.
Release Notes:
- N/A
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 }`

While zed itself is not a heavy user of rayon, wasmtime is, especially
for compilation. This change is similar to the rayon default but we
halve the number of threads still so we don't spawn too many threads
overall.

Deals with https://github.com/zed-industries/zed/issues/5259
Highlights brackets with different colors based on their depth.
Uses existing tree-sitter queries from brackets.scm to find brackets,
uses theme's accents to color them.
https://github.com/user-attachments/assets/cc5f3aba-22fa-446d-9af7-ba6e772029da
1. Adds `colorize_brackets` language setting that allows, per language
or globally for all languages, to configure whether Zed should color the
brackets for a particular language.
Disabled for all languages by default.
2. Any given language can opt-out a certain bracket pair by amending the
brackets.scm like `("\"" @open "\"" @close) ` -> `(("\"" @open "\""
@close) (#set! rainbow.exclude))`
3. Brackets are using colors from theme accents, which can be overridden
as
```jsonc
"theme_overrides": {
"One Dark": {
"accents": ["#ff69b4", "#7fff00", "#ff1493", "#00ffff", "#ff8c00", "#9400d3"]
}
},
```
Release Notes:
- Added bracket colorization (rainbow brackets) support. Use
`colorize_brackets` language setting to enable.

This is an in-progress work on changing how task scheduler affects
performance of project search. Instead of relying on tasks being
executed at a discretion of the task scheduler, we want to experiment
with having a set of "agents" that prioritize driving in-progress
project search matches to completion over pushing the whole thing to
completion. This should hopefully significantly improve throughput &
latency of project search.
This PR has been reverted previously in #40831.
Release Notes:
- Improved project search performance in local projects.

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

Using `shlex` unconditionally is dangerous as it assumes the underlying
shell is POSIX which is not the case for PowerShell, CMD, or Nushell.
Therefore, whenever we want to quote the args we should utilise our
helper `util::shell::ShellKind::try_quote` which takes into account
which shell is being used to actually exec/spawn the invocation.

This PR adds the ability to control the capabilities granted to
extensions by the extension host via the new
`granted_extension_capabilities` setting.
This setting is a list of the capabilities granted to any extension
running in Zed.
The currently available capabilities are:
- `process:exec` - Grants extensions the ability to invoke commands
using
[`zed_extension_api::process::Command`](https://docs.rs/zed_extension_api/latest/zed_extension_api/process/struct.Command.html)
- `download_file` - Grants extensions the ability to download files
using
[`zed_extension_api::download_file`](https://docs.rs/zed_extension_api/latest/zed_extension_api/fn.download_file.html)
- `npm:install` - Grants extensions the ability to install npm packages
using
[`zed_extension_api::npm_install_package`](https://docs.rs/zed_extension_api/latest/zed_extension_api/fn.npm_install_package.html)
Each of these capabilities has parameters that can be used to customize
the permissions.
For instance, to only allow downloads from GitHub, the `download_file`
capability can specify an allowed `host`:
```json
[
{ "kind": "download_file", "host": "github.com", "path": ["**"] }
]
```
The same capability can also be granted multiple times with different
parameters to build up an allowlist:
```json
[
{ "kind": "download_file", "host": "github.com", "path": ["**"] },
{ "kind": "download_file", "host": "gitlab.com", "path": ["**"] }
]
```
When an extension is not granted a capability, the associated extension
APIs protected by that capability will fail.
For instance, trying to use `zed_extension_api::download_file` when the
`download_file` capability is not granted will result in an error that
will be surfaced by the extension:
```
Language server phpactor:
from extension "PHP" version 0.4.3: failed to download file: capability for download_file https://github.com/phpactor/phpactor/releases/download/2025.07.25.0/phpactor.phar is not granted by the extension host
```
Release Notes:
- Added a `granted_extension_capabilities` setting to control the
capabilities granted to extensions.
This allows to filter by main zed binary or remote server crashes, as
well as easily tell whether a crash happened in a remote-server binary
or not.
Release Notes:
- N/A
