This PR revamps our feature flag system, to enable richer iteration.
Feature flags can now:
- Support enum values, for richer configuration
- Be manually set via the settings file
- Be manually set via the settings UI
This PR also adds a feature flag to demonstrate this behavior, a
`agent-thread-worktree-label`, which controls which how the worktree tag
UI displays.

All of the important changes are in
[`db.rs`](https://github.com/zed-industries/zed/pull/51809/changes#diff-2f644eab943bfa58feec29256281a3d9e8d4d7784cd34783e845af8beb15b16d).
Consider reading the commit log in order to review this work.
The DB crate's macro and API was changed to fix flakiness observed in
the MultiWorkspace tests when run locally. This flakiness was caused by
a shared `static LazyLock`, that caused concurrent test runs to interact
with the same underlying in-memory database. This flakiness wasn't
possible on CI due to it's usage of `cargo nextest`, whose
process-per-test approach masked this problem.
Essentially, I've changed the `static_connection` macro to remove the
static database variable and redone the internal model. Now, all
database types are thin wrappers around a generic `AppDatabase`. The
`AppDatabase` collects all of the individual table's migrations via the
`inventory` crate, and so only runs the migrations once on startup,
rather than a dozen times on startup.
The new API requires a `cx` so that we can replace the database returned
at runtime, rather than relying exclusively on a process-global
thread-local. However, we are still using a `static LazyLock` so that we
only need to take an `&App`, instead of an `&mut App`. These databases
types are `Clone + Send + Sync`, so you can easily capture-and-move the
database into background tasks and other places that don't have a `cx`.
For tests that require database isolation, it is now possible to set
their own database in init. See
[`workspace::init_test`](https://github.com/zed-industries/zed/pull/51809/changes#diff-041673bbd1947a35d45945636c0055429dfc8b5985faf93f8a8a960c9ad31e28R13610),
for the flakiness fix.
Best part, this change should be entirely compiler driven, so the Zed
agent was able to make the app-wide refactor easily.
Before you mark this PR as ready for review, make sure that you have:
- [x] Added a solid test coverage and/or screenshots from doing manual
testing
- [x] Done a self-review taking into account security and performance

Previously, if you wanted to have a button that contains icons on both
edges, you'd need to use a `ButtonLike` component, which takes any
children. Meanwhile, the `Button` would only take one icon, where you
could control its position through the `IconPosition` enum. This has
always felt unnecessarily limiting. So, this PR removes this limitation
by adding two new methods to the button: `start_icon` and `end_icon`.
In the meantime, I have also been bothered by the unnecessary
indirection in the `IconButton` due to the existence of the `ButtonIcon`
component. So I figured I could also completely eliminate that by adding
some of its methods directly to the `IconButton` and in the Button, just
using a regular `Icon` component.
---
## Before
```rust
Button::new("id", "Label")
.icon(IconName::Plus)
.icon_position(IconPosition::Start)
.icon_size(IconSize::Small)
.icon_color(Color::Muted)
```
## After
```rust
Button::new("id", "Label")
.start_icon(Icon::new(IconName::Check))
.end_icon(Icon::new(IconName::ChevronDown).size(IconSize::XSmall))
```
This should have no visual impact to the UI.

This adds `debug_panel::Toggle` which is the same as
`terminal_panel::Toggle` but for the debug panel. It also moves
`debug_panel::{Toggle, ToggleFocus}` to its own `pub mod` for
consistency with other keybinds.
[Related
discussion](https://github.com/zed-industries/zed/discussions/47931#discussion-9404091)
Release Notes:
- Added `debug_panel::Toggle` to show/hide debug panel like
`terminal_panel::Toggle`
Closes #ISSUE
Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

This PR adds a button to close the panel when it is docked to the
bottom. Effectively, the button triggers the same `ToggleBottomDock`
action that clicking on the button that opened the panel triggers, but I
think having it there just makes it extra obvious how to close it, which
is beneficial.
As a bonus, also fixed the panel controls container height when it is
docked to the sides, so it perfectly aligns with the panel tabbar
height.

- In the launch tab of the new session mode, I've switched it to use the
`InputField` component instead given that had all that we needed
already. Allows for removing a good chunk of editor-related code
- Also in the launch tab, added support for keyboard navigation between
all of the elements there (dropdown, inputs, and switch component)
- Added some simple an empty state treatment for the breakpoint column
when there are none set

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

Closes#39172
This refactors when we resolve UI keybindings in an effort to reduce
flickering whilst painting these: Previously, we would always resolve
these upon creating the binding. This could lead to cases where the
corresponding context was not yet available and no binding could be
resolved, even if the binding was then available on the next presented
frame. Following that, on the next rerender of whatever requested this
keybinding, the keybind for that context would then be found, we would
render that and then also win a layout shift in that process, as we went
from nothing rendered to something rendered between these frames.
With these changes, this now happens less often, because we only look
for the keybinding once the context can actually be resolved in the
window.

Also reduced cloning in the keymap editor in this process, since that
requiered changing due to this anyway.
Release Notes:
- Fixed some cases where keybinds would appear with a slight delay,
causing a flicker in the process
I love keybindings.
I spend way to much time thinking about them.
I also REALLY like working in Zed.
so far, however, I have found the key context system in Zed to be less
flexible than in VSCode.
the HUGE context that is available in VSCode helps you create
keybindings for very specific targeted scenarios.
the tree like structure of the Zed key context means you loose some
information as focus moves throughout the application.
For example, it is not currently possible to create a keybinding in the
editor that will only work when one of the Docks is open, or if a
specific dock is open.
this would be useful in implementing solutions to ideas like #24222
we already have an action for moving focus to the dock, and we have an
action for opening/closing the dock, but to my knowledge (very limited
lol) we cannot determine if that dock *is open* unless we are focused on
it.
I think it is possible to create a more flexible key binding system by
adding more context information to the higher up context ancestors.
while:
```
Workspace right_dock=GitPanel
Dock
GitPanel
Editor
```
may seem redundant, it actually communicates fundamentally different
information than:
```
Workspace right_dock=GitPanel
Pane
Editor
```
the first says "the GitPanel is in the right hand dock AND IT IS
FOCUSED",
while the second means "Focus is on the Editor, and the GitPanel just
happens to be open in the right hand dock"
This change adds a new set of identifiers to the `Workspace` key_context
that will indicate which docks are open and what is the specific panel
that is currently visible in that dock.
examples:
- `left_dock=ProjectPanel`
- `bottom_dock=TerminalPanel`
- `right_dock=GitPanel`
in my testing the following types of keybindings seem to be supported
with this change:
```jsonc
// match for any value of the identifier
"context": "Workspace && bottom_dock"
"context": "Workspace && !bottom_dock"
// match only a specific value to an identifier
"context": "Workspace && bottom_dock=TerminalPanel"
// match only in a child context if the ancestor workspace has the correct identifier
"context": "Workspace && !bottom_dock=DebugPanel > Editor"
```
some screen shots of the context matching in different circumstances:

the persistent_name values for `ProjectPanel` and `OutlinePanel` needed
to be updated to not have a space in them in order to pass the
`Identifier` check. all the other Panels already had names that did not
include spaces, so it just makes these conform with the other ones.
I think this is a great place to start with adding more context
identifiers and i think this type of additional information will make it
possible to create really dynamic keybindings!
Release Notes:
- Workspace key context now includes the state of the 3 docks
Fixes#39998
Debugpy and pylsp are installed in a Zed-global venv with pip. We need a
Python interpreter to create this venv when it doesn't exist and one of
these tools needs to be installed, and sometimes we attempt to use
`python3` from `$PATH`. This can cause issues on Windows, where out of
the box `python3` is a sort of shim that opens the Microsoft Store app.
This PR changes the debugpy installation path to create the Zed-global
venv using the Python interpreter from a venv in the project, and only
use python3 from `$PATH` if that fails. That matches how pylsp
installation already works. It also tightens up how we search for a
global Python installation by doing a basic sanity check (`python3 -c
'print(1 + 2)`) before accepting it, which should catch the Windows
shim.
Release Notes:
- windows: improved the behavior of Zed in situations where no global
Python installation exists.
Closes https://github.com/zed-industries/zed/issues/38690Closes#37353
### Background
On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.
Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.
### Solution
Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.
The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).

This button already exists in the main menu, as well as the "New
Session" view in the debugger panel. However, this view disappears after
starting the debugging session. This PR adds the same button to the
debugger control strip that remains accessible. This is convenient for
people editing their debug.json frequently.
Site-node: I feel like the `Cog` icon would be more appropriate, but I
picked `Code` to stay consistent with the "New Session" view.

Release Notes:
- Added additional context to debug task selection
Adding additional context when selecting a debug task to help with
projects that have multiple config files with similar names for tasks.
I think there is room for improvement, especially adding context for a
LanguageTask type. I started but it looked like it would need to add a
path value to that and wanted to make sure this was a good idea before
working on that.
Also any thoughts on the wording if you do like this format?

This PR cleans up some emitted events around the codebase. These events
are either never emitted or never listened for.
It seems better to re-implement these at some point should they again be
needed - this ensures that they will actually be fired in the cases
where they are needed as opposed to being there and getting unreliable
and stale (which is already the case for the majority of the events
removed here).
Lastly, this ensures the `CapabilitiesChanged` event is not fired too
often.

This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.

I also removed a debug assertion that wasn't true when a debug session
was restarting through a request, because there wasn't a booting task
Zed needed to run before the session.
I renamed SessionState::Building to SessionState::Booting as well,
because building implies that we're building code while booting the
session covers more cases and is more accurate.

This solves problems where users couldn't shut down sessions while
locators or build tasks are running.
I renamed `debugger::Session::Mode` enum to `SessionState` to be more
clear when it's referenced in other crates. I also embedded the boot
task that is created in `SessionState::Building` variant. This allows
sessions to shut down all created threads in their boot process in a
clean and idiomatic way.
Finally, I added a method on terminal that allows killing the active
task.
Release Notes:
- Debugger: Allow shutting down debug sessions while they're booting up
This PR updates the debugger panel's session list to be more useful in
some cases that are commonly hit when using the JavaScript adapter. We
make two adjustments, which only apply to JavaScript sessions:
- For a child session that's the only child of a root session, we
collapse it with its parent. This imitates what VS Code does in the
"call stack" view for JavaScript sessions.
- When a session has exactly one thread, we label the session with that
thread's name, instead of the session label provided by the DAP. VS Code
also makes this adjustment, which surfaces more useful information when
working with browser sessions.
Closes#33072

Restarting sessions was broken in #33273 when we moved away from calling
`kill` in the shutdown sequence. This PR re-adds that `kill` call so
that old debug adapter processes will be cleaned up when sessions are
restarted within Zed. This doesn't re-introduce the issue that motivated
the original changes to the shutdown sequence, because we still send
Disconnect/Terminate to debug adapters when quitting Zed without killing
the process directly.
We also now remove manually-restarted sessions eagerly from the session
list.
Closes#33916
Release Notes:
- debugger: Fixed not being able to restart sessions for Debugpy and
other adapters that communicate over TCP.
