- Remove RunnableVariant::Compat variant entirely
- Update PlatformScheduler::timer() to use async_task::Builder with RunnableMeta
- Update REPL's ZedDispatcher to wrap external Runnable with metadata
- Simplify all platform dispatchers (Mac, Linux, Windows, Test):
- Remove Compat match arms
- Use let-binding pattern for single-variant enum
- Remove unused trampoline_compat function from Mac dispatcher
All tasks now carry source location information for better debugging
and profiling. The RunnableVariant enum is now single-variant and
could be simplified further in a future change.
Both GPUI and scheduler Task types now have identical APIs:
- ready(val) - create a task with an immediate value
- is_ready() - check if task has completed
- detach() - run task to completion in background
The only difference is GPUI's detach_and_log_err() which requires App context.
Phase 2a partial - Unified RunnableMeta:
- Re-export RunnableMeta from scheduler crate in gpui/src/platform.rs
- Remove GPUI's duplicate RunnableMeta struct definition
- Remove RunnableVariant::Scheduler variant (now uses Meta for both)
- Update all platform dispatchers to remove Scheduler variant handling
- Update PlatformScheduler to use RunnableVariant::Meta
Phase 3c - Execution tracking:
- Add execution_hash and execution_count to TestScheduler state
- Add execution_hash(), execution_count(), reset_execution_tracking() methods
- Update step() to track execution order via location hashing
- Enables determinism verification in tests
Note: Waiting hints (Phase 3b) skipped - TestScheduler already has
superior pending_traces system with TracingWaker that automatically
captures backtraces for all pending futures.
This commit integrates the scheduler crate's TestScheduler into GPUI's
TestDispatcher for deterministic testing. The TestDispatcher now uses
TestScheduler for:
- Clock/timing (via scheduler.clock())
- Random number generation (via scheduler.rng())
- Block-on tick configuration
GPUI's TestDispatcher maintains its own task queues (foreground, background,
delayed) because it needs to handle RunnableVariant with multiple variants
(Meta, Compat, Scheduler) that TestScheduler cannot process directly.
Key changes:
- TestDispatcher::new() now takes a seed (u64) instead of StdRng
- Clock and RNG are delegated to TestScheduler
- Added RunnableVariant::Scheduler for scheduler-based runnables
- Updated all platform dispatchers to handle the new variant
KNOWN ISSUE: Tests hang after completion. After running the collab
'workspace' tests, the test process hangs indefinitely after these pass:
- test_contact_requests
- test_server_restarts
- test_random_channel_buffers
- test_random_project_collaboration
The hang likely relates to teardown/cleanup when TestDispatcher shares
state with TestScheduler. Need to investigate:
1. Whether blocked_sessions in TestScheduler is properly cleaned up
2. Whether there are threads being parked that never get unparked
3. Whether the test macro teardown sequence interacts badly with scheduler
The test had a race condition where LSP request handlers were registered
AFTER typing the trigger character. Whether this worked depended on task
scheduling order, which varies by seed.
Changes:
- Move handler setup BEFORE typing the trigger character in the test
- Make TestDispatcher::spawn_realtime panic to prevent future non-determinism
from real OS threads escaping the deterministic test scheduler
- Add execution_hash() and execution_count() to TestDispatcher for debugging
- Add DEBUG_SCHEDULER=1 logging for task execution tracing
- Document the investigation in situation.md
Add the repository name when:
- there's more than one repository, and
- the name of the active repository doesn't match the name of the
project (to avoid stuttering with the adjacent project switcher button)
Release Notes:
- The branch name in the title bar now includes the name of the current
repository when needed to disambiguate.
- Edit prediction providers can now be configured through the settings
UI
- Cleaned up the status bar menu to only show _configured_ providers
- Added to the status bar icon button tooltip the name of the active
provider
- Only display the data collection functionality under "Privacy" for the
Zed models
- Moved the Codestral edit prediction provider out of the Mistral
section in the agent panel into the settings UI
- Refined and improved UI and states for configuring GitHub Copilot as
both an agent and edit prediction provider
#### Todos before merge:
- [x] UI: Unify with settings UI style and tidy it all up
- [x] Unify Copilot modal `impl`s to use separate window
- [x] Remove stop light icons from GitHub modal
- [x] Make dismiss events work on GitHub modal
- [ ] Investigate workarounds to tell if Copilot authenticated even when
LSP not running
Release Notes:
- settings_ui: Added a section for configuring edit prediction providers
under AI > Edit Predictions, including Codestral and GitHub Copilot.

This fixes an issue where a user could get confused by the branch picker
because it would only show the 10 most recent branches, instead of all
branches.
Release Notes:
- git: Show all branches in branch picker when search field is empty
We were panicking whenever something went wrong with an example in the
CLI. This can be very disruptive when running many examples, and e.g a
single request fails. Instead, if running more than one example, errors
will now be logged alongside instructions to explore and re-run the
example by itself.

You can still opt in to stop as soon as en error occurs with the new
`--failfast` argument.

- Limit status lines to 10 in case `max_parallelism` is specified with a
grater value
- Handle logging gracefully rather than writing over it when clearing
status lines
Release Notes:
- N/A
Currently we have a single cache for this data shared between all
snapshots which is incorrect, as we might update the cache to a new
version while having old snapshots around which then may try to access
new data with old offsets/rows.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
Update the issue template used for "Report a bug" to include a field
specifically for the user's keymap file, as we've seen multiple cases
where we end up asking the users for their custom keymap, to ensure that
they're not overriding existing defaults.
Release Notes:
- N/A
- Fix missing font features in
`git_ui::blame_ui::GitBlameRenderer.render_blame_entry`
- Fix missing buffer font features in
`markdown_preview::markdown_renderer`
- Update the way that the markdown style is built for hover popovers so
that, for code blocks, the buffer font features are used.
- Introduce `gpui::Styled.font_features` to allow callers to also set
the font's features, similar to how `gpui::Styled.font_family` already
exists.
Relates to #44209
Release Notes:
- Fixed wrong font features in Blame UI, Hover Popover and Markdown

Closes#41567
We were using the git panel editor to check the focus where the commit
modal has its only editor.
Release Notes:
- Fixed an issue where commit and amend actions wouldn’t trigger when
using keybinds in the commit modal.
Update the behavior of `git::Amend` to ensure that the latest head
commit message, if available, is always loaded into the commit message
editor, regardless of its state. The previous text, if any, is now also
restored after the amend is finished.
- Update `FakeGitRepository.show` to include a message in the returned
`CommitDetails` so we can assert that this specific commit message is
set in the commit message editor.
- Add default implementation for `FakeGitRepository.commit` and
`FakeGitRepository.run_hook` to ensure that tests are able to run and
don't panic on `unimplemented!()`
- Refactor `GitPanel.load_last_commit_message_if_empty` to
`GitPanel.load_last_commit_message`, ensuring that the head commit
message is always loaded, regardless of whether the commit message
editor is empty.
- Update `GitPanel.commit_changes` to ensure that the pending amend
state is only updated if the editor managed to actually commit the
changes. This also ensures that we don't restore the commit message
editor's contents when amending a commit, before the amend is actually
processed.
- Update `CommitModal.amend`, removing the call to
`GitPanel.set_amend_pending` as that is now handled by the background
task created in `GitPanel.commit_changes`.
- Split the `commit` and `amend` methods from the event handlers so that
the methods can be called directly, as is now being done by
`CommitModal.on_commit` and `CommitModal.on_amend`.
Release Notes:
- Updated the `git: amend` command to always load the latest head
commit message, and to restore any previously entered text in the commit
message editor after the amend completes
This also applies to `cargo clean` one.
Closes#20873
Release Notes:
- rust: Changed cwd of tasks that spawn a binary target to the root of a
current package (which used to be a directory of the current source
file).
Closes#21324
Adds four new commands:
- `markdown::MoveUp`, `markdown::MoveDown` - these scroll up and down in
markdown preview mode, by no more than the height of a large headline.
- `markdown::MoveUpByItem`, and `markdown::MoveDownByItem` - these
scroll up and down by the height of the item at the top of the markdown
preview window. So headlines and large codeblocks, for instance, scroll
further than individual paragraph lines.
Also attempts to create sensible defaults:
`down` -> `markdown::ScrollDown`
`up` -> `markdown::ScrollUp`
`alt-down` -> `markdown::ScrollDownByItem`
`alt-up` -> `markdown::ScrollUpByItem`
And in Vim:
`ctrl-u` -> `markdown::ScrollPageUp`
`ctrl-d` -> `markdown::ScrollPageDown`
`ctrl-e` -> `markdown::ScrollDown`
`ctrl-y` -> `markdown::ScrollUp`
Release Notes:
- Added commands `markdown::ScrollUp`, `markdown::ScrollDown`,
`markdown::ScrollUpByItem`, and `markdown::ScrollDownByItem`
- Changed commands `markdown::MovePageUp` to `markdown::ScrollPageUp`
and `markdown::MovePageDown` to `markdown::ScrollPageDown`
