I wanted a way to make it easy to figure out which version of a language
server Zed is running. Now, you get a tooltip when hovering on a
language server in the Language Servers popover.

/>
This PR also fixes a bug. We had existing code to open a tooltip on
these language server entrees and display the language server message,
which was never fully wired up for `CustomEntry`s. Now, in this PR, we
will show show either version, message, or both, in the documentation
aside, depending on what the server has given us.
Mostly done with Droid (using GPT-5.2), with manual review and multiple
follow ups to guide it into using existing patterns in the codebase,
when it did something abnormal.
Release Notes:
- Added language server version in a tooltip on language server hover

Leverages a new `await_on_background` API that spawns the future on the

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.
Release Notes:
- N/A
Prior we only logged the crate in `log_err`, which is not too helpful.
We now assemble the module path from the file system path.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
Part of reworking our installation handling to allow for multiple
different versions to be handled
Release Notes:
- Fixed pre-release lsp fetching setting not having an affect until
restarting Zed
Follow-up to #35250. Let's experiment with having this by default on
nightly.
Release Notes:
- Added built-in support for the basedpyright language server for Python
code. basedpyright is now enabled by default, and pyright (previously
the primary Python language server) remains available but is disabled by
default. This supersedes the basedpyright extension, which can be
uninstalled. Advantages of basedpyright over pyright include support for
inlay hints, semantic highlighting, auto-import code actions, and
stricter type checking. To switch back to pyright, add the following
configuration to settings.json:
```json
{
"languages": {
"Python": {
"language_servers": ["pyright", "pylsp", "!basedpyright"]
}
}
}
```

Instead of holding a connection for potentially long LSP queries (e.g.
rust-analyzer might take minutes to look up a definition), disconnect
right after sending the initial request and handle the follow-up
responses later.
As a bonus, this allows to cancel previously sent request on the local
Collab clients' side due to this, as instead of holding and serving the
old connection, local clients now can stop previous requests, if needed.
Current PR does not convert all LSP requests to the new paradigm, but
the problematic ones, deprecating `MultiLspQuery` and moving all its
requests to the new paradigm.
Release Notes:
- Improved resource usage when querying LSP over Collab

We used to not respond at all to requests that we didn't have a handler
for, which is yuck. It may have left the language server waiting for the
response for no good reason. The other (worse) finding is that we did
not have a full definition of an Error type for LSP, which made it so
that a spec-compliant language server would fail to deserialize our
response (with an error). This then could lead to all sorts of
funkiness, including hangs and crashes on the language server's part.

- Switches to the debounce task pattern for diagnostic summary
computations, which most importantly lets us do them only once when a
large number of DiagnosticUpdated events are received at once.
- Makes workspace diagnostic requests not time out if a partial result
is received.
- Makes diagnostics from workspace diagnostic partial results get
merged.
There might be some related areas where we're not fully complying with
the LSP spec but they may be outside the scope of what this PR should
include.
Release Notes:
- Added support for streaming LSP workspace diagnostics.
- Fixed editor freeze from large LSP workspace diagnostic responses.
Follow up: #18634Closes#33328
Release Notes:
- Fixed language server shutdown process to prevent race conditions and
improper termination by waiting for shutdown confirmation before closing
connections.
The major change in schemars 1.0 is that now schemas are represented as
plain json values instead of specialized datatypes. This allows for more
concise construction and manipulation.
This change also improves how settings schemas are generated. Each top
level settings type was being generated as a full root schema including
the definitions it references, and then these were merged. This meant
generating all shared definitions multiple times, and might have bugs in
cases where there are two types with the same names.
Now instead the schemar generator's `definitions` are built up as they
normally are and the `Settings` trait no longer has a special
`json_schema` method. To handle types that have schema that vary at
runtime (`FontFamilyName`, `ThemeName`, etc), values of
`ParameterizedJsonSchema` are collected by `inventory`, and the schema
definitions for these types are replaced.
To help check that this doesn't break anything, I tried to minimize the
overall [schema
diff](https://gist.github.com/mgsloan/1de549def20399d6f37943a3c1583ee7)
with some patches to make the order more consistent + schemas also
sorted with `jq -S .`. A skim of the diff shows that the diffs come
from:
* `enum: ["value"]` turning into `const: "value"`
* Differences in handling of newlines for "description"
* Schemas for generic types no longer including the parameter name, now
all disambiguation is with numeric suffixes
* Enums now using `oneOf` instead of `anyOf`.

This PR addresses to fix (#31308) a race condition where auto-indent (in
buffer.cs) and on-type-formatting (in lsp_store.rs) concurrently
calculate indentation using the same buffer snapshot.
Previous Solution (Abandoned):
https://github.com/zed-industries/zed/pull/31340
Final Solution:
Delay applying on-type-formatting until auto-indent is complete.
Issue:
If AutoindentMode finishes first, formatting works correctly. If
"Formatting on typing" starts before AutoindentMode completes, it
results in double indentation.
Closes#31308
Release Notes:
- Fixed a race condition resulting in incorrect buffer contents when combining auto-indent and on-type-formatting
https://github.com/user-attachments/assets/ad0fa304-e4fb-4598-877d-c02141f35d6f
Closes https://github.com/zed-industries/zed/issues/4678
Also adds the code to support `textDocument/colorPresentation`
counterpart that serves as a resolve mechanism for the document colors.
The resolve itself is not run though, and the editor does not
accommodate color presentations in the editor yet — until a well
described use case is provided.
Use `lsp_document_colors` editor settings to alter the presentation and
turn the feature off.
Release Notes:
- Start showing inline previews for LSP document colors
Follow-up of https://github.com/zed-industries/zed/pull/19230
Implements the workspace diagnostics pulling, and replaces "pull
diagnostics every open editors' buffer" strategy with "pull changed
buffer's diagnostics" + "schedule workspace diagnostics pull" for the
rest of the diagnostics.
This means that if the server does not support the workspace diagnostics
and does not return more in linked files, only the currently edited
buffer has its diagnostics updated.
This is better than the existing implementation that causes a lot of
diagnostics pulls to be done instead, and we can add more heuristics on
top later for querying more diagnostics.
Release Notes:
- N/A
Closes [#13107](https://github.com/zed-industries/zed/issues/13107)
Enabled pull diagnostics by default, for the language servers that
declare support in the corresponding capabilities.
```
"diagnostics": {
"lsp_pull_diagnostics_debounce_ms": null
}
```
settings can be used to disable the pulling.
Release Notes:
- Added support for the LSP `textDocument/diagnostic` command.
# Brief
This is draft PR that implements the LSP `textDocument/diagnostic`
command. The goal is to receive your feedback and establish further
steps towards fully implementing this command. I tried to re-use
existing method and structures to ensure:
1. The existing functionality works as before
2. There is no interference between the diagnostics sent by a server and
the diagnostics requested by a client.
The current implementation is done via a new LSP command
`GetDocumentDiagnostics` that is sent when a buffer is saved and when a
buffer is edited. There is a new method called `pull_diagnostic` that is
called for such events. It has debounce to ensure we don't spam a server
with commands every time the buffer is edited. Probably, we don't need
the debounce when the buffer is saved.
All in all, the goal is basically to get your feedback and ensure I am
on the right track. Thanks!

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!(...));`

This PR uses Tree Sitter to show inline values while a user is in a
debug session.
We went with Tree Sitter over the LSP Inline Values request because the
LSP request isn't widely supported. Tree Sitter is easy for
languages/extensions to add support to. Tree Sitter can compute the
inline values locally, so there's no need to add extra RPC messages for
Collab. Tree Sitter also gives Zed more control over how we want to show
variables.
There's still more work to be done after this PR, namely differentiating
between global/local scoped variables, but it's a great starting point
to start iteratively improving it.

I wanted this for CONL (https://conl.dev )'s nascent langauge server,
and it seems like most of the support was already wired up on the LSP
side, so this surfaces it into the editor.
Release Notes:
- Added support for the `insert_text_mode` field of completions from the
language server protocol.
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
