Cherry-picked Kb/wasm panics (#35319)
Follow-up of https://github.com/zed-industries/zed/pull/34208
Closes https://github.com/zed-industries/zed/issues/35185
Previous code assumed that extensions' language server wrappers may leak
only in static data (e.g. fields that were not cleared on deinit), but
we seem to have a race that breaks this assumption.
1. We do clean `all_lsp_adapters` field after
https://github.com/zed-industries/zed/pull/34334 and it's called for
every extension that is unregistered.
2. `LspStore::maintain_workspace_config` ->
`LspStore::refresh_workspace_configurations` chain is triggered
independently, apparently on `ToolchainStoreEvent::ToolchainActivated`
event which means somewhere behind there's potentially a Python code
that gets executed to activate the toolchian, making
`refresh_workspace_configurations` start timings unpredictable.
3. Seems that toolchain activation overlaps with plugin reload, as
`2025-07-28T12:16:19+03:00 INFO [extension_host] extensions updated.
loading 0, reloading 1, unloading 0` suggests in the issue logs.
The plugin reload seem to happen faster than workspace configuration
refresh in
c65da547c9/crates/project/src/lsp_store.rs (L7426-L7456)
as the language servers are just starting and take extra time to respond
to the notification.
At least one of the `.clone()`d `adapter`s there is the adapter that got
removed during plugin reload and has its channel closed, which causes a
panic later.
----------------------------
A good fix would be to re-architect the workspace refresh approach, same
as other accesses to the language server collections.
One way could be to use `Weak`-based structures instead, as definitely
the extension server data belongs to extension, not the `LspStore`.
This is quite a large undertaking near the extension core though, so is
not done yet.
Currently, to stop the excessive panics, no more `.expect` is done on
the channel result, as indeed, it now can be closed very dynamically.
This will result in more errors (and backtraces, presumably) printed in
the logs and no panics.
More logging and comments are added, and workspace querying is replaced
to the concurrent one: no need to wait until a previous server had
processed the notification to send the same to the next one.
Release Notes:
- Fixed warm-related panic happening during startup

Closes#31917
Previously, as of #28457 we used a hack, creating an empty transaction
in the history that we then merged formatting changes into in order to
correctly identify concurrent edits to the buffer while formatting was
happening. This caused issues with noop formatting however, as using the
normal API of the buffer history (in an albeit weird way) resulted in
the redo stack being cleared, regardless of whether the formatting
transaction included edits or not, which is the correct behavior in all
other contexts.
This PR fixes the redo issue by codifying the behavior formatting wants,
that being the ability to push an empty transaction to the history with
no other side-effects (i.e. clearing the redo stack) to detect
concurrent edits, with the tradeoff being that it must then manually
remove the transaction later if no changes occurred from the formatting.
The redo stack is still cleared when there are formatting edits, as the
individual format steps use the normal `{start,end}_transaction` methods
which clear the redo stack if the finished transaction isn't empty.
Release Notes:
- Fixed an issue where redo would not work after buffer formatting
(including formatting on save) when the formatting did not result in any
changes
Supersedes: #34242
Creates an `ActionArgumentsEditor` that implements the required logic to
have a JSON language server run when editing keybinds so that there is
auto-complete for action arguments.
This is the first time action argument schemas are required by
themselves rather than inlined in the keymap schema. Rather than add all
action schemas to the configuration options we send to the JSON LSP on
startup, this PR implements support for the
`vscode-json-language-server` extension to the LSP whereby the server
will request the client (Zed) to resolve URLs with URI schemes it does
not recognize, in our case `zed://`. This limits the impact on the size
of the configuration options to ~1KB as we send URLs for the language
server to resolve on demand rather than the schema itself. My
understanding is that this is how VSCode handles JSON schemas as well. I
plan to investigate converting the rest of our schema generation logic
to this method in a follow up PR.

Closes https://github.com/zed-industries/zed/discussions/33979
- 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.
Closes#33442
Release Notes:
- Resolved an issue where the ESLint language server returned an empty
string for the CodeDescription.href field in diagnostics, leading to
missing diagnostics in editor.
Fixes an issue that caused Windows to fail when removing extension's
directories, as Zed had never stop any related processes.
Now:
* Zed shuts down and waits until the end when the language servers are
shut down
* Adds `impl Drop for WasmExtension` where does
`self.tx.close_channel();` to stop a receiver loop that holds the "lock"
on the extension's work dir.
The extension was dropped, but the channel was not closed for some
reason.
* Does more unregistration to ensure `Arc<WasmExtension>` with the `tx`
does not leak further
* Tidies up the related errors which had never reported a problematic
path before

### Improves debug console autocompletion behavior
This PR fixes a regression in completion trigger support for the debug
console, as we only looked if a completion trigger, was in the beginning
of the search text, but we also had to check if the current text is a
word so we also show completions for variables/input that doesn't start
with any of the completion triggers.
We now also leverage DAP provided information to sort completion items
more effectively. This results in improved prioritization, showing
variable completions above classes and global scope types.
I also added for completion the documentation field, that directly comes
from the DAP server. NOTE: I haven't found an adapter that returns this,
but it needs to have.

Release Notes:
- Debugger: Improve autocompletion sorting for debug console
- Debugger: Fix autocompletion menu now shown when you type
- Debugger: Fix completion item showing up twice for some adapters
This fixes an issue where lower-priority language servers cannot provide
contentful responses even when the first capable server returned empty
responses.
Most of the diffs are copypasted since the existing implementations were
also copypasted.
Release Notes:
- Improved Go to Definition / Declaration / Type Definition /
Implementation and Find All References to include all results from
different language servers
This PR revives zed-industries/zed#27818 and aims to complete the
partially implemented overloaded signature help feature.
The first commit is a rebase of zed-industries/zed#27818, and the
subsequent commit addresses all review feedback from the original PR.
Now the overloaded signature help works like

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`.

* Fixes inlay colors spoiled after document color displayed
* Optimizes the query pattern for large multi buffers
Release Notes:
- Fixed document colors issues with other inlays and multi buffers
Closes https://github.com/zed-industries/zed/issues/33522
Turns out a bunch of Zed requests were not checking their capabilities
correctly, due to odd copy-paste and due to default that assumed that
the capabilities are met.
Adjust the code, which includes the document colors, add the test on the
colors case.
Release Notes:
- Fixed excessive document colors requests for unrelated files

The tool still looks like designed by professional developers, and still
may change its UX based on the internal feedback.

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
I don't have a concrete misbehavior from it, but this update of
`insert_range` doesn't make sense for two reasons:
* If the resolved completion doesn't have a new `text_edit` it would
clear out the `insert_range`.
* It doesn't update the completion if it has already been resolved,
except this update of `insert_range` happened before that.
Guessing it was written this way because this field needed to only be
mutated within the `CompletionSource::Lsp` case and this was a
convenient match below.

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
Do not cleanup the result_id data on buffer drop, as this data is meant
to be stored between buffer reopens.
Use `LanguageServerId` as keys as this way it's simpler to access the
data.

`BufferId` can change between file reopens: e.g. open the buffer, close
it, go back in history to reopen it — the 2nd one will have a different
`BufferId`, but the same `result_ids` semantically.

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
Follow-up of https://github.com/zed-industries/zed/pull/19230
* starts to send `result_id` in pull requests to allow servers to reply
with non-full results
* fixes a bug where disk-based diagnostics were offset after pulling the
diagnostics
* fixes a bug due to which pull diagnostics could not be disabled
* uses better names and comments for the workspace pull diagnostics part

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!

Follow-up of https://github.com/zed-industries/zed/pull/30707
The old code does something odd, re-accessing essentially the same
adapter-server pair for every language server initialized; but that was
done before for "incorrect", non-reused worktree_id hence never resulted
in external worktrees' files registration in this code path.
Release Notes:
- Fixed certain external worktrees' files sometimes not registered with
language servers
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.
This reverts commit 1e55e88c18.
Closes #ISSUE
Release Notes:
- Python toolchain selector now uses path to the closest pyproject.toml
as a basis for picking a toolchain. All files under the same
pyproject.toml (in filesystem hierarchy) will share a single virtual
environment. It is possible to have multiple Python virtual environments
selected for disjoint parts of the same project.
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
Adds a new `agent.model_parameters` setting that allows the user to
specify a custom temperature for a provider AND/OR model:
```json5
"model_parameters": [
// To set parameters for all requests to OpenAI models:
{
"provider": "openai",
"temperature": 0.5
},
// To set parameters for all requests in general:
{
"temperature": 0
},
// To set parameters for a specific provider and model:
{
"provider": "zed.dev",
"model": "claude-3-7-sonnet-latest",
"temperature": 1.0
}
],
```
Release Notes:
- agent: Allow customizing temperature by provider/model
