Closes#32068Closes#15653
Not entirely sure that it fixes the latter issue, but I am fairly
certain given the comments in #32068 and the available logs in the
issue.
This PR fixes an issue where the Supermaven provider would not leave the
"Initializing" stage. This happened due to the downloaded binary missing
executable permissions. The change here ensures that freshly downloaded
binaries as well as existing binaries downloaded by Zed have executable
permissions set. I decided on also adding this for the latter since
existing downloads would continue to be broken and Supermaven does not
seem to change versions often given the logs provided by users.
While I was at it, I also added a `make_file_executable` to the util
crate mirroring the method of the `zed_extensions_api` and refactored
existing usages where possible to use that method instead. This makes
the code slightly more readable in my opinion, yet adds a method to
non-unix systems that practically does nothing. I can revert this should
that be preferred.
Release Notes:
- Fixed an issue where the Supermaven completion provider would not
leave the "Initializing" stage.

Prevent extensions from blocking async threads by enabling epoch
interruption with 100ms intervals. Extensions will yield control back to
the executor regularly during Future::poll operations.
Addresses the
[discussion](https://github.com/zed-industries/zed/discussions/24515)
that goes into depth on why this is important when enabling async
support with Wasmtime.

I can now load a custom Ruby extensions with all bells and whistles and
use it as my debugger.

This changes the way context servers are organised. We now store a
`source` which indicates if the MCP server is configured manually or
managed by an extension.

Closes#29032
This PR fixes an issue where reconnecting to SSH Remote would result in
a broken language server.
This was caused by SSH clients not registering because the `ssh_clients`
map would still contain an entry from a previously killed SSH server.
For fix, now we also check if its value has been dropped.
Release Notes:
- Fixed issue where reconnecting to SSH Remote would result in broken
code completions and diagnostics.
Before this I'd get log lines like
> ERROR [project] missing `database_url` setting
Now it's:
> ERROR [project] from extension "Postgres Context Server" version
0.0.3: missing `database_url` setting
Release Notes:
- N/A
Also adds reuse of the markdown documentation cache even when
completions are re-queried, so that markdown documentation doesn't
flicker when `is_incomplete: true` (completions provided by rust
analyzer always set this)
Release Notes:
- Added support for filtering language server completions instead of
re-querying.
We now actually call dap_schema provided by extensions instead of
defaulting to a null `serde_json::Value`. We still need to update the
Json LSP whenever a new dap is installed.
Release Notes:
- N/A
This PR allows DAPs to define their own schema so users can see
completion items when editing their debug.json files.
Users facing this aren’t the biggest chance, but behind the scenes, this
affected a lot of code because we manually translated common fields from
Zed's config format to be adapter-specific. Now we store the raw JSON
from a user's configuration file and just send that.
I'm ignoring the Protobuf CICD error because the DebugTaskDefinition
message is not yet user facing and we need to deprecate some fields in
it.
Release Notes:
- debugger beta: Show completion items when editing debug.json
- debugger beta: Breaking change, debug.json schema now relays on what
DAP you have selected instead of always having the same based values.

Builds on top of https://github.com/zed-industries/zed/pull/30942
This turns on incremental compilation and decreases extension
compilation times by up to another 41%
Putting us at roughly 92% improved extension load times from what is in
the app today.
Because we only have a static engine, I can't reset the cache between
every run. So technically the benchmarks are always running with a
warmed cache. So the first extension we load will take the 8.8ms, and
then any subsequent extensions will be closer to the measured time in
this benchmark.
This is also measuring the entire load process, not just the
compilation. However, since this is the loading we likely think of when
thinking about extensions, I felt it was likely more helpful to see the
impact on the overall time.
This works because our extensions are largely the same Wasm bytecode
(SDK code + std lib functions etc) with minor changes in the trait impl.
The more different that extensions implementation is, there will be less
benefit, however, there will always be a large part of every extension
that is always the same across extensions, so this should be a speedup
regardless.
I used `moka` to provide a bound to the cache. We could use a bare
`DashMap`, however if there was some issue this could lead to a memory
leak. `moka` has some slight overhead, but makes sure that we don't go
over 32mb while using an LRU-style mechanism for deciding which
compilation artifacts to keep.
I measured our current extensions to take roughly 512kb in the cache.
Which means with a cap of 32mb, we can keep roughly 64 *completely
novel* extensions with no overlap. Since our extensions will have more
overlap than this though, we can actually keep much more in the cache
without having to worry about it.
#### Before:

Release Notes:

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`
Release Notes:
- N/A
Extensions cannot look up available port themselves, hence the new API.
With this I'm able to port our Ruby implementation into an extension.
Release Notes:
- N/A
Precursor to other optimizations, but this already gets us a big
improvement.
Wasm compilation can easily be parallelized, and with all of the cores
on my M4 Max this already gets us an 86% improvement, bringing loading
an extension down to <9ms.
Not all setups will see this much improvement, but it will use the cores
available (it just uses rayon under the hood like we do elsewhere).
Since we load extensions in sequence, this should have a nice impact for
users with a lot of extensions.

Release Notes:

- Languages now define their preferred debuggers in `config.toml`.
- `LanguageRegistry` now exposes language config even for languages that
are not yet loaded. This necessitated extension registry changes (we now
deserialize config.toml of all language entries when loading new
extension index), but it should be backwards compatible with the old
format. /cc @maxdeviant

Because we instantiated `ContextServerManager` both in `agent` and
`assistant-context-editor`, and these two entities track the running MCP
servers separately, we were effectively running every MCP server twice.
This PR moves the `ContextServerManager` into the project crate (now
called `ContextServerStore`). The store can be accessed via a project
instance. This ensures that we only instantiate one `ContextServerStore`
per project.
Also, this PR adds a bunch of tests to ensure that the
`ContextServerStore` behaves correctly (Previously there were none).

`App::http_client` and `Client::http_client` both return an owned `Arc`

when calling these methods.

Things this doesn't currently handle:
- [x] ~testing~
- ~we really need an snapshot test that takes a vscode settings file
with all options that we support, and verifies the zed settings file you
get from importing it, both from an empty starting file or one with lots
of conflicts. that way we can open said vscode settings file in vscode
to ensure that those options all still exist in the future.~
- Discussed this, we don't think this will meaningfully protect us from
future failures, and we will just do this as a manual validation step
before merging this PR. Any imports that have meaningfully complex
translation steps should still be tested.
- [x] confirmation (right now it just clobbers your settings file
silently)
- it'd be really cool if we could show a diff multibuffer of your
current settings with the result of the vscode import and let you pick
"hunks" to keep, but that's probably too much effort for this feature,
especially given that we expect most of the people using it to have an
empty/barebones zed config when they run the import.
- [x] ~UI in the "welcome" page~
- we're planning on redoing our welcome/walkthrough experience anyways,
but in the meantime it'd be nice to conditionally show a button there if
we see a user level vscode config
- we'll add it to the UI when we land the new walkthrough experience,
for now it'll be accessible through the action
- [ ] project-specific settings
- handling translation of `.vscode/settings.json` or `.code-workspace`
settings to `.zed/settings.json` will come in a future PR, along with UI
to prompt the user for those actions when opening a project with local
vscode settings for the first time
- [ ] extension settings
- we probably want to do a best-effort pass of popular extensions like
vim and git lens
- it's also possible to look for installed/enabled extensions with `code
--list-extensions`, but we'd have to maintain some sort of mapping of
those to our settings and/or extensions
- [ ] LSP settings
- these are tricky without access to the json schemas for various
language server extensions. we could probably manage to do translations
for a couple popular languages and avoid solving it in the general case.
- [ ] platform specific settings (`[macos].blah`)
- this is blocked on #16392 which I'm hoping to address soon
- [ ] language specific settings (`[rust].foo`)
- totally doable, just haven't gotten to it yet
~We may want to put this behind some kind of flag and/or not land it
until some of the above issues are addressed, given that we expect
people to only run this importer once there's an incentive to get it
right the first time. Maybe we land it alongside a keymap importer so
you don't have to go through separate imports for those?~
We are gonna land this as-is, all these unchecked items at the bottom
will be addressed in followup PRs, so maybe don't run the importer for
now if you have a large and complex VsCode settings file you'd like to
import.
Release Notes:
- Added a VSCode settings importer, available via a
`zed::ImportVsCodeSettings` action

This adds a "workspace-hack" crate, see
[mozilla's](https://hg.mozilla.org/mozilla-central/file/3a265fdc9f33e5946f0ca0a04af73acd7e6d1a39/build/workspace-hack/Cargo.toml#l7)
for a concise explanation of why this is useful. For us in practice this
means that if I were to run all the tests (`cargo nextest r
--workspace`) and then `cargo r`, all the deps from the previous cargo
command will be reused. Before this PR it would rebuild many deps due to
resolving different sets of features for them. For me this frequently
caused long rebuilds when things "should" already be cached.
To avoid manually maintaining our workspace-hack crate, we will use
[cargo hakari](https://docs.rs/cargo-hakari) to update the build files
when there's a necessary change. I've added a step to CI that checks
whether the workspace-hack crate is up to date, and instructs you to
re-run `script/update-workspace-hack` when it fails.
Finally, to make sure that people can still depend on crates in our
workspace without pulling in all the workspace deps, we use a `[patch]`
section following [hakari's
instructions](https://docs.rs/cargo-hakari/0.9.36/cargo_hakari/patch_directive/index.html)
One possible followup task would be making guppy use our
`rust-toolchain.toml` instead of having to duplicate that list in its
config, I opened an issue for that upstream: guppy-rs/guppy#481.
TODO:
- [x] Fix the extension test failure
- [x] Ensure the dev dependencies aren't being unified by Hakari into
the main dependencies
- [x] Ensure that the remote-server binary continues to not depend on
LibSSL

Closes#18153
When calling `uninstall_extension`, the `work_dir` associated with this
`extension` doesn't have its corresponding `FileHandle` properly closed,
preventing the deletion of the `work_dir`. As seen in the image below,
after installing the `toml` extension, `zed.exe` holds two `Handle`s for
the folder `C:\Users\36477\AppData\Local\Zed\extensions\work\toml`.

Therefore, after deleting `extension_dir` and then calling
`this.update(...)`, `zed.exe` releases these two `Handles`, and only
then can the folder
`C:\Users\36477\AppData\Local\Zed\extensions\work\toml` be deleted. See
the corresponding file handles are closed after calling
`this.update(...)`:

However, if there is a running server of the extension, the error will
persist. At this point, I haven’t found a direct way to terminate all
running servers of the extension. Since this feature might affect the
`LspStore` structure, I paused my work here.
See when `toml` extension is running, we can not delete
`C:\Users\36477\AppData\Local\Zed\extensions\work\toml` since
`C:\Users\36477\AppData\Local\Zed\extensions\work\toml\taplo.exe` is
still running:

Closes https://github.com/zed-industries/zed/issues/14334, allowing
users to set environment variables for a language server binary like:
```json
"lsp": {
"rust-analyzer": {
"binary": {
"path": "/Users/dbarsky/.cargo/bin/rust-analyzer",
"env": {
"RA_PROFILE": "*>100"
}
},
}
}
```
The newly introduced environment variables are merged with the shell
environment. Perhaps more controversially, I've _also_ removed the
trimming/`stderr:`-prefixing of language server logs. This because
rust-analyzer has some nice, tree-shaped profiling built-in, and it
prevents us from printing profiles like this:

Release Notes:
- Added the ability to set a language server's environment variables.
- Removed the `stderr`-prefix of a language server's stderr logs.
This PR fixes an issues where the commands returned from context server
extensions were being used as-is instead of interpreting them relative
to the extension's work dir.
