* Rename `-S common` to `-S cli`.
The "common" in `-S common` came from "wasi-common" which came from the
idea of having code in common between Wasmtime, Lucet, and others. It
doesn't have a clear meaning for end users, and has a risk of being
interpreted as "common" functionality that's generally available
everywhere.
This PR renames `-S common` to `-S cli`, and documents it as including
the WASI CLI APIs, to clarify its purpose `-S common` is still accepted,
with a warning.
* Fix formatting in RELEASES.md.
* Disable the warning about `-S common` for now.
This commit makes it so that the library type for core dumps is serializable
into the standard binary format for core dumps.
Additionally, this commit makes it so that we use the library type for
generating core dumps in the CLI. We previously were using a one-off
implementation of core dump generation that only had backtrace information and
no instances, modules, globals, or memories included. The library type has all
that information, so the core dumps produced by our CLI will both be more
featureful and be generated by shared code paths going forward.
Along the way, implementing all this required some new helper methods sprinkled
throughout `wasmtime` and `wasmtime-runtime`:
* `wasmtime::Instance::module`: get the module that a `wasmtime::Instance` is an
instance of. This is public, since it seems generally useful. This involved
adding a new return value from `ModuleRegistry::register_module` that is an
identifier that can be used to recover a reference to the registered module.
* `wasmtime::Instance::all_{globals,memories}`: get the full global/memory index
space. I made these `pub(crate)` out of caution. I don't think we want to commit
to exposing non-exported things in the public API, even if we internally need
them for debugging-related features like core dumps. These also needed
corresponding methods inside `wasmtime-runtime`.
* `wasmtime::{Global,Memory}::hash_key`: this was needed to work around the fact
that each time you call `{Global,Memory}::from_wasmtime`, it creates a new
entry in the `StoreData` and so you can get duplicates. But we need to key some
hash maps on globals and memories when constructing core dumps, so we can't
treat the underlying `Stored<T>` as a hash key because it isn't stable across
duplicate `StoreData` entries. So we have these new methods. They are only
`pub(crate)`, are definitely implementation details, and aren't exposed in the
public API.
* `wasmtime::FrameInfo::module`: Each frame in a backtrace now keeps a handle to
its associated module instead of just the name. This is publicly exposed
because it seems generally useful. This means I also deprecated
`wasmtime::FrameInfo::module_name` since you can now instead do
`frame.module().name()` to get that exact same info. I updated callers inside
the repo.
* x64: Fix an off-by-one in in `i64x2.shr_s`
This commit fixes a mistake from #6372 where one of the immediates to a
`pshufd` instruction was off-by-one in terms of bits. This fixes the
behavior of the wasm `i64x2.shr_s` instruction with constant shift
amounts larger than 32.
* Update release notes
* Partially revert CLI argument changes from #6737
This commit is a partial revert of #6737. That change was reverted
in #6830 for the 12.0.0 release of Wasmtime and otherwise it's currently
slated to get released with the 13.0.0 release of Wasmtime. Discussion
at today's Wasmtime meeting concluded that it's best to couple this
change with #6925 as a single release rather than spread out across
multiple releases. This commit is thus the revert of #6737, although
it's a partial revert in that I've kept many of the new tests added to
showcase the differences before/after when the change lands.
This means that Wasmtime 13.0.0 will exhibit the same CLI behavior as
12.0.0 and all prior releases. The 14.0.0 release will have both a new
CLI and new argument passing semantics. I'll revert this revert (aka
re-land #6737) once the 13.0.0 release branch is created and `main`
becomes 14.0.0.
* Update release notes
* Add some initial release notes for 13.0.0
May need more updates over the coming days, but this should document
everything up-to-now.
* Review comments
* Update release date of Wasmtime 12.0.0
* Update date to today

* Wasmtime: Rename `IndexAllocator` to `ModuleAffinityIndexAllocator`
We will have multiple kinds of index allocators soon, so clarify which one this
is.
* Wasmtime: Introduce a simple index allocator
This will be used in future commits refactoring the pooling allocator.
* Wasmtime: refactor the pooling allocator for components
We used to have one index allocator, an index per instance, and give out N
tables and M memories to every instance regardless how many tables and memories
they need.
Now we have an index allocator for memories and another for tables. An instance
isn't associated with a single instance, each of its memories and tables have an
index. We allocate exactly as many tables and memories as the instance actually
needs.
Ultimately, this gives us better component support, where a component instance
might have varying numbers of internal tables and memories.
Additionally, you can now limit the number of tables, memories, and core
instances a single component can allocate from the pooling allocator, even if
there is the capacity for that many available. This is to give embedders tools
to limit individual component instances and prevent them from hogging too much
of the pooling allocator's resources.
* Remove unused file
Messed up from rebasing, this code is actually just inline in the index
allocator module.
* Address review feedback
* Fix benchmarks build
* Fix ignoring test under miri
The `async_functions` module is not even compiled-but-ignored with miri, it is
completely `cfg`ed off. Therefore we ahve to do the same with this test that
imports stuff from that module.
* Fix doc links
* Allow testing utilities to be unused
The exact `cfg`s that unlock the tests that use these are platform and feature
dependent and ends up being like 5 things and super long. Simpler to just allow
unused for when we are testing on other platforms or don't have the compile time
features enabled.
* Debug assert that the pool is empty on drop, per Alex's suggestion
Also fix a couple scenarios where we could leak indices if allocating an index
for a memory/table succeeded but then creating the memory/table itself failed.
* Fix windows compile errors
