Microsoft had decided to switch over to a different releasing strategy,
autogenerating all releases and not publishing tarballs anymore.
But it was not enough, and they had also removed old tarballs, including
a relatively old `2.4.4` version release's tarballs, which broke Zed
downloads.
See https://github.com/microsoft/vscode-eslint/issues/1954

This PR uses
https://github.com/zed-industries/vscode-eslint/releases/tag/2.4.4 from
Zed's fork, manually released for the same tag.

This approach is merely a stub before more sustainable solution is
found, and I think we need to pivot into downloading *.vsix from
https://open-vsx.org/extension/dbaeumer/vscode-eslint but this is quite
a change so not done right now.

Release Notes:

- Fixed eslint 404 downloads

Release Notes:

- Fixed cmd-shift-e / ctrl-shift-e (`pane::RevealInProjectPanel` /
`project_panel::ToggleFocus`) to better my VSCode behavior

Closes #ISSUE

Release Notes:

- vim: Add support for `ctrl-w _` and `ctrl-w =`

Closes #8628

Release Notes:

- Added support for resizing the current pane using vim keybinds with
the intention to follow the functionality of vim
  - "ctrl-w +" to make a pane taller 
  - "ctrl-w -" to make the pane shorter
  - "ctrl-w >" to make a pane wider
  - "ctrl-w <" to make the pane narrower
- Changed vim pre_count and post_count to globals to allow for other
crates to use the vim count. In this case, it allows for resizing by
more than one unit. For example, "10 ctrl-w -" will decrease the height
of the pane 10 times more than "ctrl-w -"
- This pr does **not** add keybinds for making all panes in an axis
equal size and does **not** add support for resizing docks. This is
mentioned because these could be implied by the original issue

Closes #20858

This fix depends on the sanitization logic implemented in PR #20577.
Since that branch may undergo further changes, this branch will be
periodically rebased on it. Once #20577 is merged, the dependency will
no longer apply.

Release Notes:

- Fix missing or duplicated files when copying multiple items in the
project panel.
- Fix marked files not being deselected after selecting a directory on
primary click.
- Fix "copy path" and "copy path relative" with multiple items selected
in project panel.

**Problem**:

In this case, `dir1` is selected while `dir2`, `dir3`, and `dir1/file`
are marked. Using the `marked_entries` function results in only `dir1`,
which is incorrect.

<img height="120"
src="https://github.com/user-attachments/assets/d4d92cc5-c998-4948-9a58-25c4f54167f2"
/>

Currently, the `marked_entries` function is used in five actions, which
all produce incorrect results:

1. Delete (via the disjoint function)
2. Copy 
3. Cut
4. Copy Path
5. Copy Path Relative

**Solution**:

1. `marked_entries` function should not use "When currently selected
entry is not marked, it's treated as the only marked entry." logic.
There is no grand scheme behind this logic as confirmed by piotr
[here](https://github.com/zed-industries/zed/issues/17746#issuecomment-2464765963).
2. `copy` and `cut` actions should use the disjoint function to prevent
obivous failures.
3. `copy path` and `copy path relative` should keep using *fixed*
`marked_entries` as that is expected behavior for these actions.

1. Before/After: Partial Copy

Select `dir1` and `c.txt` (in that order, reverse order works!), and
copy it and paste in `dir2`. `c.txt` is not copied in `dir2`.

2. Before/After: Duplicate Copy

Select `a.txt`, `dir1` and `c.txt` (in that order), and copy it and
paste in `dir2`. `a.txt` is duplicated in `dir2`.

3. Before/After: Directory Selection

Simply primary click on any file, now primary click on any dir. That
previous file is still marked.

/>

---
4. Before/After: Copy Path and Copy Path Relative

Upon `copy path` (ctrl + alt + c):

Before: Only `/home/tims/test/dir2/a.txt` was copied.
After: All three paths `/home/tims/test/dir2`, `/home/tims/test/c.txt`
and `/home/tims/test/dir2/a.txt` are copied.

This is also how VSCode also copies path when multiple are selected.

Release Notes:

Change the "Apply" and "Discard" buttons to match @danilo-leal's design!
Here are some different states:

### Cursor in the first hunk

Now that the cursor is in a particular hunk, we show the "Apply" and
"Discard" names, and the keyboard shortcut. If I press the keyboard
shortcut, it will only apply to this hunk.

### Cursor in the second hunk

Moving the cursor to a different hunk changes which buttons get the
keyboard shortcut treatment. Now the keyboard shortcut is shown next to
the hunk that will actually be affected if you press that shortcut.

This PR adds a checkbox to the `assistant2` message editor to control
whether tools should be used for a given message.

Release Notes:

- N/A

Fix cmd-pipe
Remove redudnant jetbrains/sublime keybinds (these exist as `cmd-{` and `cmd-}` under default vscode keymap) and were broken as part of the recent keybind changes.
Remove excess JSON whitespace from tests to make them more readable.

Follow-up of https://github.com/zed-industries/zed/pull/21173

Rust-analyzer with `checkOnSave` enabled will push diagnostics for a
file after each diagnostics refresh (e.g. save, file open, file close).

If there's a file that is not open in any pane and has only warnings,
and the diagnostics editor has warnings toggled off, then

0. rust-analyzer will push the corresponding warnings after initial load
1. the diagnostics editor code registers
`project::Event::DiagnosticsUpdated` for the corresponding file path and
opens the corresponding buffer to read its associated diagnostics from
the snapshot
2. opening the buffer would send `textDocument/didOpen` which would
trigger rust-analyzer to push the same diagnostics
3. meanwhile, the diagnostics editor would filter out all diagnostics
for that buffer, dropping the open buffer and effectively closing it
4. closing the buffer will send `textDocument/didClose` which would
trigger rust-analyzer to push the same diagnostics again, as those are
`cargo check` ones, still present in the file
5. GOTO 1

Release Notes:

- Fixed diagnostics editor not scrolling properly under certain
conditions

- Closes https://github.com/zed-industries/zed/issues/21185

Release Notes:

- Fixed incorrect handling of the completion list defaults

This PR restructures the storage of the tool uses and results in
`assistant2` so that they don't live on the individual messages.

It also introduces a `LanguageModelToolUseId` newtype for better type
safety.

Release Notes:

- N/A

This PR styles the messages in `assistant2` so they don't look quite as
rough:

Release Notes:

- N/A

This PR adds rudimentary support for using tools to `assistant2`. There
are currently no visual affordances for tool use.

This is gated behind the `assistant-tool-use` feature flag.

Release Notes:

- N/A

This PR factors the tool definitions out of the `assistant` crate so
that they can be shared between `assistant` and `assistant2`.

`ToolWorkingSet` now lives in `assistant_tool`. The tool definitions
themselves live in `assistant_tools`, with the exception of the
`ContextServerTool`, which has been moved to the `context_server` crate.

As part of this refactoring I needed to extract the
`ContextServerSettings` to a separate `context_server_settings` crate so
that the `extension_host`—which is referenced by the `remote_server`—can
name the `ContextServerSettings` type without pulling in some undesired
dependencies.

Release Notes:

- N/A

This PR wires up the `assistant2::NewThread` action so that you can
create new threads.

Release Notes:

- N/A

This PR improves the tracking of pending completions in `assistant2`
such that we actually remove ones that have been completed.

Release Notes:

- N/A

This PR makes it so previous messages in the thread are included when
constructing the completion request, instead of only sending up the most
recent user message.

Release Notes:

- N/A

This PR removes an unnecessary `Pane` that was copied over from
`assistant::AssistantPanel` to `assistant2::AssistantPanel`.

Release Notes:

- N/A

This PR makes it so that the completion text streams into the message
list rather than being buffered until the end.

Release Notes:

- N/A

This is a pure refactor, motivated by wanting to introduce to the
BufferStore new logic for opening staged and committed changes.

I found the `BufferStoreImpl` trait a little bit confusing, particularly
how the different implementors of the trait held a handle back to the
owning buffer store. I was able to reduce the amount of code
considerably (-78 lines) by using a two-variant enum instead, similar to
what we do for `LspStore`, `WorktreeStore` and `Worktree`.

Release Notes:

- N/A

This PR adds in rudimentary functionality for sending messages to the
LLM in `assistant2`.

@bennetbo @as-cii @mrnugget I'm really not liking the hints about AI on
every line. It feels too distracting to me and damaging to the user

Closes #ISSUE

Release Notes:

- pylsp will now use version installed in user venv, if one is
available.

Release Notes:

- Add `string.doc` python syntax highlighting to class and module-level
docstrings.

Previously, only docstrings inside python functions were labeled as
`string.doc`, but docstrings can exist at the class or module level too.
This adds the more specific string type for each of those.

- Unify welcome page event type string structure
- Differentiate between metric telemetry event and diagnostic telemetry
event

Release Notes:

- N/A

This needs scrutinized. Detailed breakdown of what events I kept and
threw out here:

https://zed.dev/channel/app-events-17178/notes

I also removed a few fake events and tossed out json properties that
were being inserted for things we don't have logic to track. See PR
review comments below.

I think the only bad data we have are that we were identifying all node,
pnpm, and yarn projects as 'node' in the `project_type` property, so a
few days of lost data there.

Release Notes:

This PR factors the language model selector out into its own
`language_model_selector` crate so that it can be reused in
`assistant2`.

Also renamed it from `ModelSelector` to `LanguageModelSelector` to be a
bit more specific.

Release Notes:

- N/A

This PR breaks ground on a new `assistant2` crate.

In order to see this new version of the assistant, both of the following
must be true:
1. The `assistant2` feature flag is enabled for your user
   - It is **not** currently enabled for all staff.
2. You are running a development build of Zed

The intent here is to enable the folks working on `assistant2` to
incrementally land work onto `main` without breaking use of the current
Assistant for anyone.
