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

Thread stacks in rust by default have 2 megabytes of stack which for
sumtrees (or ropes in this case) can easily be exceeded depending on the
workload.
Release Notes:
- Fixed stack overflows when constructing large ropes
We only use it a handful of times and the default amount of threads
(logical cpu core number) its spawns is overkill for this. This also
gives the threads names oppose to being labeled `<unknown>`

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 is a refactoring PR to simplify our environment loading code by:
- Getting rid of `EnvironmentErrorMessage` in favor of using
`anyhow::Result` everywhere, with a separate `mpsc` channel to
communicate statuses that will be shown in the activity indicator
- Inlining some functions that were only called once to reduce
indirection
- Removing the separate `direnv` module
Release Notes:

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.
Release Notes:
- Improved project search performance

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
Closes #ISSUE
Improves the efficiency of our interactions with the Zed language
server. Previously, on startup and after every workspace configuration
changed notification, we would send >1MB of JSON Schemas to the JSON
LSP. The only reason this had to happen was due to the case where an
extension was installed that would result in a change to the JSON schema
for settings (i.e. added language, theme, etc).
This PR changes the behavior to use the URI LSP extensions of
`vscode-json-language-server` in order to send the server URI's that it
can then use to fetch the schemas as needed (i.e. the settings schema is
only generated and sent when `settings.json` is opened. This brings the
JSON we send to on startup and after every workspace configuration
changed notification down to a couple of KB.
Additionally, using another LSP extension request we can notify the
server when a schema has changed using the URI as a key, so we no longer
have to send a workspace configuration changed notification, and the
schema contents will only be re-requested and regenerated if the schema
is in use.
Release Notes:
- Improved the efficiency of communication with the builtin JSON LSP.
JSON Schemas are no longer sent to the JSON language server in their
full form. If you wish to view a builtin JSON schema in the language
server info tab of the language server logs (`dev: open language server
logs`), you must now use the `editor: open url` action with your cursor
over the URL that is sent to the server.
- Made it so that Zed urls (`zed://...`) are resolved locally when
opened within the editor instead of being resolved through the OS. Users
who could not previously open `zed://*` URLs in the editor can now do so
by pasting the link into a buffer and using the `editor: open url`
action (please open an issue if this is the case for you!).

### 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).

In the settings refactor I'd assumed server settings were like project
settings. This is not the case, they are in fact the normal user
settings;
but just read from the server.
Release Notes:

Tests that the downstream project can see custom agents configured in
the remote server's settings, and that it constructs an appropriate
`AgentServerCommand`.

In local projects, initialize the list of agents in the agent server
store immediately. Previously we were initializing the list only after a
delay, in an attempt to avoid sending the `ExternalAgentsUpdated`
message to the downstream client (if any) before its handlers were
initialized. But we already have a separate codepath for that situation,
in the `AgentServerStore::shared`, and we can insert the delay in that
place instead.
Release Notes:
- acp: Fixed a bug where starting an external agent thread soon after
Zed starts up would show a "not registered" error.

@maxdeviant We can eventually turn down the panic telemetry endpoint,
but should probably leave it up while there's still a bunch of stable
users hitting it.
@maxbrunsfeld We're optimistic that this change also fixed the macos
crashed-thread misreporting. We think it was because the
`CrashContext::exception` was getting set to `None` only on macos, while
on linux it was getting a real exception value from the sigtrap. Now
we've unified and it uses `SIGABRT` on both platforms (I need to double
check that this works as expected for windows).
We unconditionally set `RUST_BACKTRACE=1` for the current process so
that we see backtraces when running in a terminal by default. This
should be fine but I just wanted to note it since it's a bit abnormal.

Closes#37520
This change makes the attach modal load processes from the remote server
when connecting via SSH, rather than showing local processes from the
client machine.
This works by using the new GetProcessesRequest RPC message to allow
downstream clients to get the correct processes to display. It also only
works with downstream ssh clients because the message handler is only
registered on headless projects.
Release Notes:
- debugger: Fix bug where SSH attach modal showed local processes
instead of processes from the server

Noisy RPC LSP logs were functioning this way already, but to keep Collab
loaded even less, do not send any kind of logs to the client if the
client has a corresponding log tab not opened.
This change is pretty raw and does not fully cover scenarious with
multiple clients: if one client has a log tab open and another opens tab
with another kind of log, the 2nd kind of logs will be streamed only.
Also, it should be possible to forward the host logs to the client on
enabling — that is not done to keep the change smaller.
Release Notes:
- N/A
Take 2: https://github.com/zed-industries/zed/pull/36709 but without the
