5244: Add a command to compute memory usage statistics r=matklad a=jonas-schievink
This allows inspecting memory usage on a live rust-analyzer instance after it has been used interactively.
This will only work with `--features jemalloc`, so maybe it should print something more useful when that's not available? Right now it will just print 0 Bytes for every query.

5209: Fixes to memory usage stats r=matklad a=jonas-schievink
This brings the unaccounted memory down from 287mb to 250mb, and displays memory used by VFS and "other" allocations.

5192: Implement rust-analyzer feature configuration to tests. r=matklad a=daxpedda
Fixes#3198.
I'm unsure if it is desired this way, maybe we want to make a seperate configuration?

5101: Add expect -- a light-weight alternative to insta r=matklad a=matklad
This PR implements a small snapshot-testing library. Snapshot updating is done by setting an env var, or by using editor feature (which runs a test with env-var set).
Here's workflow for updating a failing test:
Here's workflow for adding a new test:
Note that colorized diffs are not implemented in this PR, but should be easy to add (we already use them in test_utils).
Main differences from insta (which is essential for rust-analyzer development, thanks @mitsuhiko!):
* self-updating tests, no need for a separate tool
* fewer features (only inline snapshots, no redactions)
* fewer deps (no yaml, no persistence)
* tighter integration with editor
* first-class snapshot object, which can be used to write test functions (as opposed to testing macros)
* trivial to tweak for rust-analyzer needs, by virtue of being a workspace member.
I think eventually we should converge to a single snapshot testing library, but I am not sure that `expect` is exactly right, so I suggest rolling with both insta and expect for some time (if folks agree that expect might be better in the first place!).
# Editor Integration Implementation
The thing I am most excited about is the ability to update a specific snapshot from the editor. I want this to be available to other snapshot-testing libraries (cc @mitsuhiko, @aaronabramov), so I want to document how this works.
The ideal UI here would be a code action (💡). Unfortunately, it seems like it is impossible to implement without some kind of persistence (if you save test failures into some kind of a database, like insta does, than you can read the database from the editor plugin). Note that it is possible to highlight error by outputing error message in rustc's format. Unfortunately, one can't use the same trick to implement a quick fix.
For this reason, expect makes use of another rust-analyzer feature -- ability to run a single test at the cursor position. This does need some expect-specific code in rust-analyzer unfortunately. Specifically, if rust-analyzer notices that the cursor is on `expect!` macro, it adds a special flag to runnable's JSON. However, given #5017 it is possible to approximate this well-enough without rust-analyzer integration. Specifically, an extension can register a special runner which checks (using regexes) if rust-anlyzer runnable covers text with specific macro invocation and do special magic in that case.

5120: Add a simple SSR subcommand to the rust-analyzer command line binary r=davidlattimore a=davidlattimore
Is adding the dependency on ra_ide_db OK? It's needed for the call to `db.local_roots()`
Co-authored-by: David Lattimore <dml@google.com>
There are two reasons why we don't want a generic ra_progress crate
just yet:
*First*, it introduces a common interface between separate components,
and that is usually undesirable (b/c components start to fit the
interface, rather than doing what makes most sense for each particular
component).
*Second*, it introduces a separate async channel for progress, which
makes it harder to correlate progress reports with the work done. Ie,
when we see 100% progress, it's not blindly obvious that the work has
actually finished, we might have some pending messages still.
