Cherry-picked Use buffer's main language when fetching language tasks
(#32580)

Closes https://github.com/zed-industries/zed/issues/32465

Release Notes:

- Fixed language tasks fetched incorrectly for certain selections

Co-authored-by: Kirill Bulatov <kirill@zed.dev>

Closes https://github.com/zed-industries/zed/issues/32316

Multi buffer design was changed so that control buttons are not
occupying extra lines, the hardcoded logic for that is obsolete thus
removed.

I didn't find an executor-agnostic watch crate that was well maintained
(we already tried postage and async-watch), so decided to implement it
our own version.

Release Notes:

- Fixed a panic that could sometimes occur when the agent performed
edits.

Fixes https://github.com/zed-industries/zed/issues/12174

Release Notes:

- Fixed a bug where ERB files were not parsed correctly when the
languages were initially loaded.

Cherry-picked Filter language server completions even when
`is_incomplete: true` (#32491)

In #31872 I changed the behavior of completions to not filter instead of
requerying completions when `is_incomplete: false`. Unfortunately this
also stopped filtering completions when `is_incomplete: true` - we still
want to filter the incomplete completions so that the menu updates
quickly even when completions are slow. This does mean that the
completions menu will display partial results, hopefully only briefly
while waiting for fresh completions.

Thanks to @mikayla-maki for noticing the regression. Thankfully just in
time to fix it before this makes it into a stable release. Leaving off
release notes since I will cherry-pick this to the current preview
version, 190.x, and there probably won't be a preview release before the
next stable.

Reverts zed-industries/zed#31399

I found that in some cases, Zed will panic when using `editor: open
selections in multibuffer` if the selection is reversed. It doesn't
happen in most cases that I've tested, but in some strange edge cases
(that I dont fully understand ATM), it does. I'm reverting for now, as
the previous behavior is better than a panic, but will re-implement this
fix to preserving selection directions in a new PR with comprehensive
testing

Release Notes:

Cherry-picked Use unix pipe to capture environment variables (#32136)

The use of `NamedTempFile` in #31799 was not secure and could
potentially cause write permission issues (see [this

comment](https://github.com/zed-industries/zed/issues/29528#issuecomment-2939672433)).
Therefore, it has been replaced with a Unix pipe.

Cherry-picked Fix buffer rendering on every mouse move (#32408)

Closes #32210

This notify was added in #13433. Solution is to only notify when the
breakpoint indicator state has changed.

Also improves the logic for enqueuing a task to delay showing - now only
does this if it isn't already visible, and that delay task now only
notifies if still hovering.

Release Notes:

- Fixed a bug where buffers render on every mouse move.

Cherry-picked No longer instantiate recently opened agent threads on
startup (#32285)

This was causing a lot of work on startup, particularly due to
instantiating edit tool cards. The minor downside is that now these
threads don't open quite as fast.

Includes a few other improvements:

* On text thread rename, now immediately updates the metadata for
display in the UI instead of waiting for reload.

* On text thread rename, first renames the file before writing. Before
if the file removal failed you'd end up with a duplicate.

* Now only stores text thread file names instead of full paths. This is
more concise and allows for the app data dir changing location.

* Renames `ThreadStore::unordered_threads` to
`ThreadStore::reverse_chronological_threads` (and removes the old one
that sorted), since the recent change to use a SQL database queries them
in that order.

* Removes `ContextStore::reverse_chronological_contexts` since it was
only used in one location where it does sorting anyway - no need to sort
twice.

* `SavedContextMetadata::title` is now `SharedString` instead of
`String`.

Release Notes:

- Fixed regression in startup performance by not deserializing and
instantiating recently opened agent threads.

Cherry-picked Fix panic dragging tabs multiple positions to the right
(#32305)

Closes https://github.com/zed-industries/zed/issues/32303

Release Notes:

- Fixed a panic that occurred when dragging tabs multiple positions to
the right (preview only)

Co-authored-by: Joseph T. Lyons <JosephTLyons@gmail.com>

Closes #32205

The issue was that in some places the end of the replacement range used
anchors with `Bias::Left` instead of `Bias::Right`. Before #31872
completions were recomputed on every change and so the anchor bias
didn't matter. After that change, the end anchor didn't move as the
user's typing. Changing it to `Bias::Right` to "stick" to the character
to the right of the cursor fixes this.

Also fixes slash command arguments to now have `is_incomplete: true`,
since some of the argument providers do limited fuzzy matching.

Release Notes:

- Fixed slash command completions in agent text threads to replace the
user's query text (Preview Only)

This was a regression with my recent fixes to pinned tabs. Dragging a
pinned tab left in the pinned region would still update the pinned tab
count, which would later cause an out-of-bounds later when it used that
value to index into a vec.

https://zed-industries.slack.com/archives/C04S6T1T7TQ/p1749220447796559

Release Notes:

https://github.com/zed-industries/zed/issues/32229
https://github.com/zed-industries/zed/issues/32230
https://github.com/zed-industries/zed/issues/32232

Release Notes:

- Fixed a bug where if the last tab was a pinned tab and it was dragged
to the right, resulting in a no-op, it would become unpinned
- Fixed a bug where a pinned tab dragged just to the right of the end of
the pinned tab region would become unpinned
- Fixed a bug where dragging a pinned tab from one pane to another
pane's pinned region could result in an existing pinned tab becoming
unpinned when `max_tabs` was reached
- Fixed a bug where moving an unpinned tab to the left, just to the end
of the pinned region, would cause the pinned tabs to become unpinned.

Fix 1: A pinned tab dragged into a new split should remain pinned


https://github.com/user-attachments/assets/608a7e10-4ccb-4219-ba81-624298c960b0

Fix 2: Moving a pinned tab from one pane to another should not cause
other pinned tabs to be unpinned


https://github.com/user-attachments/assets/ccc05913-591d-4a43-85bb-3a7164a4d6a8

I also added tests for moving both pinned tabs and unpinned tabs into
existing panes, both into the "pinned" region and the "unpinned" region.

Release Notes:

- Fixed a bug where dragging a pinned tab into a new split would lose
its pinned tab state.
- Fixed a bug where pinned tabs in one pane could be lost when moving
one of the pinned tabs to another pane.

Hi, this pull request adds `sorbet` and `steep` to the list of available
language servers for the Ruby language in order to prepare default Ruby
language settings for these LS. Both language servers are disabled by
default. We plan to add both in #104 and #102. Thanks!

Release Notes:

- ruby: Added `sorbet` and `steep` to the list of available language servers.

Removes the load_model trait method and its implementations in Ollama
and LM Studio providers, along with associated preload_model functions
and unused imports.

When `<old_text>` points to more than one location in a file, we used to
edit the first match, confusing the agent along the way. Now we will
return an error, asking to expand `<old_text>` selection.

Closes #ISSUE

Release Notes:

- agent: Fixed incorrect file edits when edit locations are ambiguous

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

It seems that there was a regression. `build_config` no longer has an
`OUT_DIR` in it.
On way to mitigate it is to stop relying on it and just use `cwd` as dir
for the test binary to be placed in.

Modify the `replace_and_mark_text_in_range` method in the `Editor` to
keep the cursor at the start of the preedit range during IME
composition. Previously, the cursor would move to the end of the preedit
text with each update, causing the IME candidate box to shift (e.g.,
when typing pinyin with Fcitx5 on Wayland). This change ensures the
cursor and candidate box remain fixed until the composition is
committed, improving the IME experience.

Closes #14496.

In https://github.com/zed-industries/zed/pull/31976, we modified the
highlighting behavior for entries when certain entries or paths are
being dragged over them. Instead of relying on marked entries for
highlighting, we introduced the `highlight_entry_id` parameter, which
determines which entry and its children should be highlighted when an
item is being dragged over it.

The rationale behind that is that we can now utilize marked entries for
various other functions, such as:

1. When dragging multiple items, we use marked entried to show which
items are being dragged. (This is already covered because to drag
multiple items, you need to use marked entries.)
2. When dragging a single item, set that item to marked entries. (This
PR)

Prep for https://github.com/zed-industries/zed/pull/32040

Currently, there’s no way to modify the cursor style of the active drag
state after dragging begins. However, there are scenarios where we might
want to change the cursor style, such as pressing a modifier key while
dragging. This PR introduces an API to update and read the current
active drag state cursor.

Zed’s current method of loading environment variables from the login
shell has two issues:
1. Some shells—​fish in particular—​​write specific escape characters to
`stdout` right before they exit. When this happens, the tail end of the
last environment variable printed by `/usr/bin/env` becomes corrupted.
2. If a multi-line value contains an equals sign, that line is
mis-parsed as a separate name-value pair.

This PR addresses those problems by:
1. Redirecting the shell command's `stdout` directly to a temporary
file, eliminating any side effects caused by the shell itself.
2. Replacing `/usr/bin/env` with `sh -c 'export -p'`, which removes
ambiguity when handling multi-line values.

Additional changes:
- Correctly set the arguments used to launch a login shell under `csh`
or `tcsh`.
- Deduplicate code by sharing the implementation that loads environment
variables on first run with the logic that reloads them for a project.
