There was a missing rest field access. In addition createTag doesn't actually create a tag, it creates a tag object. A tag object is an object which references a commit or other kind of object and has various kinds of metadata. You need to store it in a reference stored in refs/tags/ to actually show as tag in the git ui. The code to update the tag however creates a lightweight tag (which is a file in refs/tags/ which directly references a commit rather than a tag object) as such do the same when creating the initial dev tag by using createRef with a commit id as object sha.
See also https://git-scm.com/book/en/v2/Git-Internals-Git-References for the difference between a lightweight tag and an annotated tag.
* Speed up index fetches on CI
Use the `sparse` protocol from Rust 1.68.0 which should shave a minute
or two off most steps on CI.
* Update nightly toolchains in CI
prtest:full
* Fix date
Aside from a few new features (notably automatic registry suggestions), this
release removes the need to import description for criteria that are not
directly used, and adds an explicit version to the cargo-vet instance.
Noted in #5954 this'll report `cargo vet` status checks on PRs that
modify the `supply-chain` directory in addition to `Cargo.lock`
modifications that already happen.
I saw some PRs fail this step earlier today due to rate limits but it
ended up not failing the entire PR's CI due to it not being listed in
the final set of dependencies, so add it there.
* Don't run LLDB tests on PRs
These take an extra minute or so, so only run them on the full test
suite of a merge instead of on all PRs as well.
* Add a test for the x64 isa files
This guarantees that if cranelift's x64 backend is modified that the
tests will be run on a PR, even if other backends were also modified.
These mostly only validate changes to `Cargo.lock` so skip these checks
by default on PRs which generally never need to trigger them. If
`Cargo.lock` changes, however, then run them for PRs.
GitHub recently made its merge queue feature available for use in public
repositories owned by organizations meaning that the Wasmtime repository
is a candidate for using this. GitHub's Merge Queue feature is a system
that's similar to Rust's bors integration where PRs are tested before
merging and only passing PRs are merged. This implements the "not rocket
science" rule where the `main` branch of Wasmtime, for example, is
always tested and passes CI. This is in contrast to our current
implementation of CI where PRs are merged when they pass their own CI,
but the code that was tested is not guaranteed to be the state of `main`
when the PR is merged, meaning that we're at risk now of a failing
`main` branch despite all merged PRs being green. While this has
happened with Wasmtime this is not a common occurrence, however.
The main motivation, instead, to use GitHub's Merge Queue feature is
that it will enable Wasmtime to greatly reduce the amount of CI running
on PRs themselves. Currently the full test suite runs on every push to
every PR, meaning that our workers on GitHub Actions are frequently
clogged throughout weekdays and PRs can take quite some time to come
back with a successful run. Through the use of a Merge Queue, however,
we're able to configure only a small handful of checks to run on PRs
while deferring the main body of checks to happening on the
merge-via-the-queue itself. This is hoped to free up capacity on CI and
overall improve CI times for Wasmtime and Cranelift developers.
The implementation of all of this required quite a lot of plumbing and
retooling of our CI. I've been testing this in an [external
repository][testrepo] and I think everything is working now. A list of
changes made in this PR are:
* The `build.yml` workflow is merged back into the `main.yml` workflow
as the original reason to split it out is not longer applicable (it'll
run on all merges). This was also done to fit in the dependency graph
of jobs of one workflow.
* Publication of the `gh-pages` branch, the `dev` tag artifacts, and
release artifacts have been moved to a separate
`publish-artifacts.yml` workflow. This workflow runs on all pushes to
`main` and all tags. This workflow no longer actually preforms any
builds, however, and relies on a merge queue or similar being used for
branches/tags where artifacts are downloaded from the workflow run to
be uploaded. For pushes to `main` this works because a merge queue is
run meaning that by the time the push happens all artifacts are ready.
For release branches this is handled by..
* The `push-tag.yml` workflow is subsumed by the `main.yml` workflow. CI
for a tag being pushed will upload artifacts to a release in GitHub,
meaning that all builds must finish first for the commit. The
`main.yml` workflow at the end now scans commits for the preexisting
magical marker and pushes a tag if necessary.
* CI is currently a flat list of "run all these jobs" and this is now
rearchitected to a "fan out" approach where some jobs run to determine
the next jobs to run which then get "joined" into a finish step. The
purpose for this is somewhat nuanced and this has implications for CI
runtime as well. The Merge Queue feature requires branches to be
protected with "these checks must pass" and then the same checks are
gates both to enter the merge queue as well as pass the merge queue.
The saving grace, however, is that a "skipped" check counts as
passing, meaning checks can be skipped on PRs but run to completion on
the merge queue. A problem with this though is the build matrix used
for tests where PRs want to only run one element of the build matrix
ideally but there's no means on GitHub Actions right now for the
skipped entries to show up as skipped easily (or not that I know of).
This means that the "join" step serves the purpose of being the single
gate for both PR and merge queue CI and there's just more inputs to it
for merge queue CI. The major consequence of this decision is that
GitHub's actions scheduling doesn't work out well here. Jobs are
scheduled in a FIFO order meaning that the job for "ok complete the CI
run" is queued up after everything else has completed, possibly
after lots of other CI requests in the middle for other PRs. The hope
here is that by using a merge queue we can keep CI relatively under
control and this won't affect merge times too much.
* All jobs in the `main.yml` workflow will not automatically cancel the
entire run if they fail. Previously this fail-fast behavior was only
part of the matrix runs (and just for that matrix), but this is
required to make the merge queue expedient. The gate of the merge
queue is the final "join" step which is only executed once all
dependencies have finished. This means, for example, that if rustfmt
fails quickly then the tests which take longer might run for quite
awhile before the join step reports failure, meaning that the PR sits
in the queue for longer than needed being tested when we know it's
already going to fail. By having all jobs cancel the run this means
that failures immediately bail out and mark the whole job as
cancelled.
* A new "determine" CI job was added to determine what CI actually needs
to run. This is a "choke point" which is scheduled at the start of CI
that quickly figures out what else needs to be run. This notably
indicates whether large swaths of ci (the `run-full` flag) like the
build matrix are executed. Additionally this dynamically calculates a
matrix of tests to run based on a new `./ci/build-test-matrix.js`
script. Various inputs are considered for this such as:
1. All pushes, meaning merge queue branches or release-branch merges,
will run full CI.
2. PRs to release branches will run full CI.
3. PRs to `main`, the most common, determine what to run based on
what's modified and what's in the commit message.
Some examples for (3) above are if modifications are made to
`cranelift/codegen/src/isa/*` then that corresponding builder is
executed on CI. If the `crates/c-api` directory is modified then the
CMake-based tests are run on PRs but are otherwise skipped.
Annotations in commit messages such as `prtest:*` can be used to
explicitly request testing.
Before this PR merges to `main` would perform two full runs of CI: one
on the PR itself and one on the merge to `main`. Note that the one as a
merge to `main` was quite frequently cancelled due to a merge happening
later. Additionally before this PR there was always the risk of a bad
merge where what was merged ended up creating a `main` that failed CI to
to a non-code-related merge conflict.
After this PR merges to `main` will perform one full run of CI, the one
as part of the merge queue. PRs themselves will perform one test job
most of the time otherwise. The `main` branch is additionally always
guaranteed to pass tests via the merge queue feature.
For release branches, before this PR merges would perform two full
builds - one for the PR and one for the merge. A third build was then
required for the release tag itself. This is now cut down to two full
builds, one for the PR and one for the merge. The reason for this is
that the merge queue feature currently can't be used for our
wildcard-based `release-*` branch protections. It is now possible,
however, to turn on required CI checks for the `release-*` branch PRs so
we can at least have a "hit the button and forget" strategy for merging
PRs now.
Note that this change to CI is not without its risks. The Merge Queue
feature is still in beta and is quite new for GitHub. One bug that
Trevor and I uncovered is that if a PR is being tested in the merge
queue and a contributor pushes to their PR then the PR isn't removed
from the merge queue but is instead merged when CI is successful, losing
the changes that the contributor pushed (what's merged is what was
tested). We suspect that GitHub will fix this, however.
Additionally though there's the risk that this may increase merge time
for PRs to Wasmtime in practice. The Merge Queue feature has the ability
to "batch" PRs together for a merge but this is only done if concurrent
builds are allowed. This means that if 5 PRs are batched together then 5
separate merges would be created for the stack of 5 PRs. If the CI for
all 5 merged together passes then everything is merged, otherwise a PR
is kicked out. We can't easily do this, however, since a major purpose
for the merge queue for us would be to cut down on usage of CI builders
meaning the max concurrency would be set to 1 meaning that only one PR
at a time will be merged. This means PRs may sit in the queue for awhile
since previously many `main`-based builds are cancelled due to
subsequent merges of other PRs, but now they must all run to 100%
completion.

* Remove trailing whitespace in `lower.isle` files
* Legalize the `band_not` instruction into simpler form
This commit legalizes the `band_not` instruction into `band`-of-`bnot`,
or two instructions. This is intended to assist with egraph-based
optimizations where the `band_not` instruction doesn't have to be
specifically included in other bit-operation-patterns.
Lowerings of the `band_not` instruction have been moved to a
specialization of the `band` instruction.
* Legalize `bor_not` into components
Same as prior commit, but for the `bor_not` instruction.
* Legalize bxor_not into bxor-of-bnot
Same as prior commits. I think this also ended up fixing a bug in the
s390x backend where `bxor_not x y` was actually translated as `bnot
(bxor x y)` by accident given the test update changes.
* Simplify not-fused operands for riscv64
Looks like some delegated-to rules have special-cases for "if this
feature is enabled use the fused instruction" so move the clause for
testing the feature up to the lowering phase to help trigger other rules
if the feature isn't enabled. This should make the riscv64 backend more
consistent with how other backends are implemented.
* Remove B{and,or,xor}Not from cost of egraph metrics
These shouldn't ever reach egraphs now that they're legalized away.
* Add an egraph optimization for `x^-1 => ~x`
This adds a simplification node to translate xor-against-minus-1 to a
`bnot` instruction. This helps trigger various other optimizations in
the egraph implementation and also various backend lowering rules for
instructions. This is chiefly useful as wasm doesn't have a `bnot`
equivalent, so it's encoded as `x^-1`.
* Add a wasm test for end-to-end bitwise lowerings
Test that end-to-end various optimizations are being applied for input
wasm modules.
* Specifically don't self-update rustup on CI
I forget why this was here originally, but this is failing on Windows
CI. In general there's no need to update rustup, so leave it as-is.
* Cleanup some aarch64 lowering rules
Previously a 32/64 split was necessary due to the `ALUOp` being different
but that's been refactored away no so there's no longer any need for
duplicate rules.
* Narrow a x64 lowering rule
This previously made more sense when it was `band_not` and rarely used,
but be more specific in the type-filter on this rule that it's only
applicable to SIMD types with lanes.
* Simplify xor-against-minus-1 rule
No need to have the commutative version since constants are already
shuffled right for egraphs
* Optimize band-of-bnot when bnot is on the left
Use some more rules in the egraph algebraic optimizations to
canonicalize band/bor/bxor with a `bnot` operand to put the operand on
the right. That way the lowerings in the backends only have to list the
rule once, with the operand on the right, to optimize both styles of
input.
* Add commutative lowering rules
* Update cranelift/codegen/src/isa/x64/lower.isle

This fixes the build issue identified in #5664 at the toolchain level
rather than working around it in our own build. The next step in fixing
this will be to remove the nightly override in the future when the
toolchain becomes stable.
This allows the `wasmtime` binary provided in our release artifacts to
cross-compile: `wasmtime compile` can build a `.cwasm` for any platform
that Wasmtime supports, not just the host platform. This may be useful
in some deployment scenarios.
We don't turn on `all-arch` by default because it increases build time
and binary size of Wasmtime itself, and other embedders of the
`wasmtime` crate won't necessarily want this; hence, we set it only as
part of the CI build configuration.
Fixes#5655.
We accidentally broke the build for Android when introducing the jit-icache-coherence
crate. To avoid this happening again, add a check job just to ensure that it can build.
See #5323 and #5331 for context.
We accidentally broke the build for FreeBSD when introducing the jit-icache-coherence
crate. To avoid this happening again, add a check job just to ensure that it can build.
See #5323 and #5331 for context.
* Use the `sym` operator for inline assembly
Avoids extra `#[no_mangle]` functions and undue symbols being exposed
from Wasmtime. This is a newly stabilized feature in Rust 1.66.0. I've
also added a `rust-version` entry to the `wasmtime` crate to try to head
off possible reports in the future about odd error messages or usage of
unstable features if the rustc version is too old.
* Fix a s390x warning
* Add `rust-version` annotation to Wasmtime crate
As the other main entrypoint for embedders.
CI is currently broken because `ubuntu-latest` moved to 22.04, which is
missing at least one package (`libclang1-9` used in our CI jobs) and may
be causing other issues as well.
This PR pins us back to 20.04; separately we should look into upgrading
when issues are resolved.
This hopefully will speed things up slightly since ASan can add a chunk
to the compile time. Unsure if this will actually help, though, so let's
find out!
* wiggle: no longer need to guard wasmtime integration behind a feature
this existed so we could use wiggle in lucet, but lucet is long EOL
* replace wiggle::Trap with wiggle::wasmtime_crate::Trap
* wiggle tests: unwrap traps because we cant assert_eq on them
* wasi-common: emit a wasmtime::Trap instead of a wiggle::Trap
formally add a dependency on wasmtime here to make it obvious, though
we do now have a transitive one via wiggle no matter what (and therefore
can get rid of the default-features=false on the wiggle dep)
* wasi-nn: use wasmtime::Trap instead of wiggle::Trap
there's no way the implementation of this func is actually
a good idea, it will panic the host process on any error,
but I'll ask @mtr to fix that
* wiggle test-helpers examples: fixes
* wasi-common cant cross compile to wasm32-unknown-emscripten anymore
this was originally for the WASI polyfill for web targets. Those days
are way behind us now.
* wasmtime wont compile for armv7-unknown-linux-gnueabihf either
Looks like #5091 wasn't enough and some of the APIs needed updating with
changes made in the meantime. I've updated the action here and
additionally made a separate change where the release isn't continually
created and deleted but instead left alone and only the tag is updated.
This should work for the `dev` release and avoids deleting/recreating on
each PR, sending out notifications for new releases.
A local github action we have has been broken for about a month now
meaning that the `dev` tag isn't getting updated or getting new
releases. This appears to be due to the publication of new versions of
these dependencies which are running into issues using one another. I
think I've figured out versions that work and have added a
`package-lock.json` to ensure we keep using the same versions.
* Upgrade our github actions to "node16"
Each github actions run has a lot of warnings about using node12 so this
upgrades our repository to using node16. I'm hoping no other changes are
needed and I suspect other actions we're using are on node12 and will
need further updates, but this should help pin down what's remaining.
* Update `actions/checkout` workflow to `v3`
* Update to `actions/cache@v3`
* Update to `actions/upload-artifact@v3`
* Drop usage of `actions-rs/toolchain`
* Update to `actions/setup-python@v4`
* Update mdbook version
This commit fixes the `push-tag.yml` workflow to work with the new
`Cargo.toml` manifest since workspace inheritance was added. This
additionally fixes some warnings coming up on CI about our usage of
deprecated features on github actions.
In #5023 we are seeing a failing CI job (see [1]); after four attempted
restarts, it 404's each time when trying to download OpenVino from the
Intel apt mirrors.
This PR temporarily removes the wasi-nn CI job from our CI configuration
so that we have green CI and can merge other work.

* Make wasmtime build for windows-aarch64
* Add check for win arm64 build.
* Fix checks for winarm64 key in workflows.
* Add target in windows arm64 build.
* Add tracking issue for Windows ARM64 trap handling
* Leverage Cargo's workspace inheritance feature
This commit is an attempt to reduce the complexity of the Cargo
manifests in this repository with Cargo's workspace-inheritance feature
becoming stable in Rust 1.64.0. This feature allows specifying fields in
the root workspace `Cargo.toml` which are then reused throughout the
workspace. For example this PR shares definitions such as:
* All of the Wasmtime-family of crates now use `version.workspace =
true` to have a single location which defines the version number.
* All crates use `edition.workspace = true` to have one default edition
for the entire workspace.
* Common dependencies are listed in `[workspace.dependencies]` to avoid
typing the same version number in a lot of different places (e.g. the
`wasmparser = "0.89.0"` is now in just one spot.
Currently the workspace-inheritance feature doesn't allow having two
different versions to inherit, so all of the Cranelift-family of crates
still manually specify their version. The inter-crate dependencies,
however, are shared amongst the root workspace.
This feature can be seen as a method of "preprocessing" of sorts for
Cargo manifests. This will help us develop Wasmtime but shouldn't have
any actual impact on the published artifacts -- everything's dependency
lists are still the same.
* Fix wasi-crypto tests
The release process failed last night due to me filling out the dates in
the release notes early (rather than leaving "Unreleased") which mean
there were no changes for each commit. Switch to passing `--allow-empty`
when making a commit to prevent this.
* Adds a github action to support x64 performance testing using a sightglass
This github action allows performance testing using sightglass. The
action is triggered either via a workflow dispatch or with the comment
'/bench_x64', in a pull request. Once triggered the action will send
a request to a private repository that supports using a self-hosted runner
to do comparisons of "refs/feature/commit" vs "refs/heads/main" for
wasmtime. If the action is triggered via a comment in a pull request
(with '/bench_x64') then the commit referenced by the pull request is used
for the comparison against refs/head/main. If triggered via a workflow
dispatch the interface will request the commit to compare against
refs/head/main. The results of the performance tests, run via sightglass,
will be a table showing a percentage change in clock ticks in various stages
requried for executing the benchmark, namely instantiate, compiliation,
and execution. This patch is intended to be just a starting patch with much
to tweak and improve. One of the TODOs will be adding support for aarch64
.. currently this patch supports only x64. Note also that the logic for
actually doing the comparison and parsing the results occurs with the action
associated with the private repo and so this patch itself (though the trigger)
is fairly straight forward.
* Refactor patch to consolidate all steps to here.
* Remove unused code
* Remvoes unused pull_request_review_comment trigger
* Match trigger word when contained anywhere in the pull request review message
* Remove redundant repo and ref variables for wasmtime_commit
* Minor comment update
* Remove command to install jq
* Remove printing of git config variables being used
* Fix token for posting results
* Update message explaining pct_change for benchmark results
* Revert TOKEN for publsh change
* Update message explaining results
* [fuzz] Remove some differential fuzz targets
The changes in #4515 do everything the `differential_spec` and
`differential_wasmi` fuzz target already do. These fuzz targets are now
redundant and this PR removes them. It also updates the fuzz
documentation slightly.
* Add source tarballs to our releases
This commit adds a small script to create a source tarball as part of
the release process. This goes further than requested by #3808 by
vendoring all Rust dependencies as well to be more in line with
"download the source once then build somewhere without a network".
Vendoring the Rust dependencies makes the tarball pretty beefy (67M
compressed, 500M uncompressed). Unfortunately most of this size comes
from vendored crates such as v8, pqcrypto-kyber, winapi, capstone-sys,
plotters, and web-sys. Only `winapi` in this list is actually needed for
`wasmtime`-the-binary and only on Windows as well but for now this is
the state of things related to `cargo vendor`. If this becomes an issue
we could specifically remove the bulky contents of crates in the
`vendor` directory such as `v8` since it's only used for fuzzing.
