Closes#37473
### Background
Previously, we enabled foreign keys at all times for our sqlite database
that we use for client-side state.
The problem with this is that In sqlite, `alter table` is somewhat
limited, so for many migrations, you must *recreate* the table: create a
new table called e.g. `workspace__2`, then copy all of the data from
`workspaces` into `workspace__2`, then delete the old `workspaces` table
and rename `workspaces__2` to `workspaces`. The way foreign keys work in
sqlite, when we delete the old table, all of its associated records in
other tables will be deleted due to `on delete cascade` clauses.
Unfortunately, one of the types of associated records that can be
deleted are `editors`, which sometimes store unsaved text. It is very
bad to delete these records, as they are the *only* place that this
unsaved text is stored.
This has already happened multiple times as we have migrated tables as
we develop Zed, but I caused it to happened again in
https://github.com/zed-industries/zed/pull/36714.
### The Fix
The Sqlite docs recommend a multi-step approach to migrations where you:
* disable foreign keys
* start a transaction
* create a new table
* populate the new table with data from the old table
* delete the old table
* rename the new table to the old name
* run a foreign key check
* if it passes, commit the transaction
* enable foreign keys
In this PR, I've adjusted our sqlite migration code path to follow this
pattern more closely. Specifically, we disable foreign key checks before
running migrations, run a foreign key check before committing, and then
enable foreign key checks after the migrations are done.
In addition, I've added a generic query that we run *before* running the
foreign key check that explicitly deletes any rows that have dangling
foreign keys. This way, we avoid failing the migration (and breaking the
app) if a migration deletes data that *does* cause associated records to
need to be deleted.
But now, in the common case where we migrate old data in the new table
and keep the ids, all of the associated data will be preserved.
Release Notes:
- Fixed a bug where workspace state would be lost when upgrading from
Zed 0.201.x. or below.
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
This PR adds the ability to enable/disable breakpoints. It also fixes a
bug where toggling a log breakpoint from the breakpoint context menu
would add a standard breakpoint on top of the log breakpoint instead of
deleting it.
todo:
- [x] Add `BreakpointState` field Breakpoint that manages if a
breakpoint is active or not
- [x] Don't send disabled breakpoints to DAP servers - in progress
- [x] Half the opacity of disabled breakpoints - in progress
- [x] Add `BreakpointState` to database
- [x] Editor test for enabling/disabling breakpoints
- [ ] Integration Test to make sure we don't send disabled breakpoints
to DAP servers
- [x] Database test to make sure we properly serialize/deserialize
BreakpointState

- N/A

### DISCLAIMER
> As of 6th March 2025, debugger is still in development. We plan to
merge it behind a staff-only feature flag for staff use only, followed
by non-public release and then finally a public one (akin to how Git
panel release was handled). This is done to ensure the best experience
when it gets released.

There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure

Fixes https://github.com/zed-industries/zed/issues/13073
Note that, contrary to the issue's text, we're still shipping a
statically bundled sqlite3 after this PR. We use enough new features of
sqlite, like `sqlite3_error_offset` and `STRICT`, that our minimum
version (v3.38.0) is higher than is presumably accessible on Ubuntu.

Reverts zed-industries/zed#7481
This would regress performance because we'd be using the standard
library's hash maps everywhere, so reverting for now.
On Windows, `OsStr` must be a valid
[WTF-8](https://simonsapin.github.io/wtf-8/) sequence, and there are no
safety ways converting from bytes to OsStr in std. So I added
`PathExt::try_from_bytes` and use it in `sqlez`.
