Changes:
- Add interned keys to salsa (#150) -- see salsa-rs/salsa-rfcs#2
for more details.
- Fix bugs re: GC and volatile queries
- Optimization for GC (#144), though I think this later got undone
as part of the bug fixes =)
- GC API now more orthogonal + flexible (#138)
- Removed `set_unchecked` testing mechanism (#141)
- Generated enums now squelch `non_camel_case_types` lint (#135)
- Tests now using `set_foo` (#139)
- `Query::group_storage` now called `Query::query_storage` (#142)
Contributors to this release:
- @matklad
- @memoryruins
- @nikomatsakis
- You now write `#[salsa::database(query_groups...)]` instead of
`database_storage!`, and you don't ned to list individual
queries (#123, #124, #125)
- We now generate `set_foo` methods for inputs (#126)
- We can now peek at values using debug query interface (#122)
- Local handles recover from unwinds better (#114)
- We don't issue docs for `__SalsaQueryDescriptor` (#116)
- The unwind safety impls were moved about (internal refactoring, #115)

Switch to a procedural implementation of the `query_group!` macro,
residing in the `components/salsa_macros` subcrate.
Allow the user to override the invoked function via `salsa::invoke(...)`
and the name of the generated query type via `salsa::query_type(...)`.
In all tests, replace the `salsa::query_group! { ... }` invocations with
the new attribute-style `#[salsa::query_group]` macro, and change them
to the new naming scheme for query types (`...Query`).
Update README, examples, and documentation.
- Panic safety improvements (#81)
- We build on stable now (#94)
- Removed use of dynamic dispatch for constructing query
descriptors (#95)
- Technically a breaking change, though unlikely to affect clients
- Removed use of upgradable reads to avoid Amanieu/parking-lot#101 (#75)
- Upgraded parking lot (#100)
- Improved Debug output (#98)
- Snapshot implements Debug (#85)
- major refactoring to the database APIs for safer parallel
processing (#78, #82):
- To set an input, you now write `db.query_mut(Query).set(...)`,
and you must declare your database as `mut`.
- To fork a thread, you now write `db.snapshot()`, which acquires
a read-lock that is only released when the snapshot is dropped
(note that this read-lock blocks `set` from occuring on the main
thread).
- Therefore, there can only be one mutable handle to the
database; all other handles are snapshots. This eliminates a variety
of complex and error-prone usage patterns.
- introduced the `salsa_event` callback that can be used for logging
and introspection (#63)
Changes:
- correct dead locks and add parallel stress test (#72)
- we now panic if you `get` an input that has not been `set` and
we do not compare inputs for equality (thus dropped `Default` and `Eq`
bounds) (#69)
- `PanicGuard` now detects internal salsa bugs (#71)
