We have a currently unreproducible flaky e2e test. This PR captures snapshots on e2e test failures so we can better debug flaky e2e tests that don't fail locally.
Modified the `run_devtools_e2e_tests` script so that you can pass in a React version. If you pass in a version, it will build the DevTools shell and run the e2e tests with that version.
This PR adds a `--replaceBuild` option to the script that downloads older React version builds. If this flag is true, we will replace the contents of the `build` folder with the contents of the `build-regression` folder and remove the `build-regression` folder after, which was the original behavior.
However, for e2e tests, we need both the original build (for DevTools) and the new build (for the React Apps), so we need both the `build` and the `build-regression` folders. Not adding the `--replaceBuild` option will do this.
This PR also modifies the circle CI config to reflect this change.
This PR adds a script that downloads the specified react version from NPM (ie. react-dom, react, and react-test-renderer) and replaces the corresponding files in the build folder with the downloaded react files.
The scheduler package, unlike react-dom, react, and react-test-renderer, is versioned differently, so we also need to specifically account for that in the script.
Update all our local scripts to use `build` instead of `build2`.
There are still downstream scripts that depend on `build2`, though, so
we can't remove it yet.
Uses the layout of the build artifact directory to infer the format
of a given file, and which lint rules to apply.
This has the effect of decoupling the lint build job from the existing
Rollup script, so that if we ever add additional post-processing, or
if we replace Rollup, it will still work.
But the immediate motivation is to replace the separate "stable" and
"experimental" lint-build jobs with a single combined job.
* Remove /dist/ UMD builds
We publish UMDs to npm (and we're considering stopping even that).
This means we'll stop publishing to http://react.zpao.com/builds/master/latest/
* Update fixture paths
* Write size info to separate file per bundle
`bundle-sizes.json` contains the combined size information for every
build. This makes it easier to store and process, but it prevents us
from parallelizing the build script, because each process would need to
write to the same file.
So I've updated the Rollup script to output individual files per build.
A downstream CI job consolidates them into a single file.
I have not parallelized the Rollup script yet. I'll do that next.
* Parallelize the build script
Uses CircleCI's `parallelism` config option to spin up multiple build
processes.
Removes `--extract-errors` argument from CI build script command.
Instead, the author is expected to run `yarn extract-errors` locally
or manually edit the error code map.
The lint rule should be sufficient to catch unminified errors, but
as an extra precaution, I added a post-build step that greps the
production bundles. The post-build step works even if someone disables
the lint rule for a specific line or file.
Updates the CircleCI config to use the workflows features to run jobs in
parallel, instead of the `parallelism` option. This change alone doesn't
improve the overall build time much, since almost all of the total time
is spent running the Rollup script, which runs entirely sequentially.
But it does improve reporting, and should make it easier to add
additional parallel jobs in the future.
* Store FB bundles as CI artifacts
Updates the Circle CI config to store Facebook bundles as build
artifacts. We already do this for our npm packages.
* Might as well store everything in build/
* Store build directory as a tarball
So it's easy to download
* Rewrite ReactFiberScheduler
Adds a new implementation of ReactFiberScheduler behind a feature flag.
We will maintain both implementations in parallel until the new one
is proven stable enough to replace the old one.
The main difference between the implementations is that the new one is
integrated with the Scheduler package's priority levels.
* Conditionally add fields to FiberRoot
Some fields only used by the old scheduler, and some by the new.
* Add separate build that enables new scheduler
* Re-enable skipped test
If synchronous updates are scheduled by a passive effect, that work
should be flushed synchronously, even if flushPassiveEffects is
called inside batchedUpdates.
* Passive effects have same priority as render
* Revert ability to cancel the current callback
React doesn't need this anyway because it never schedules callbacks if
it's already rendering.
* Revert change to FiberDebugPerf
Turns out this isn't neccessary.
* Fix ReactFiberScheduler dead code elimination
Should initialize to nothing, then assign the exports conditionally,
instead of initializing to the old exports and then reassigning to the
new ones.
* Don't yield before commit during sync error retry
* Call Scheduler.flushAll unconditionally in tests
Instead of wrapping in enableNewScheduler flag.
* Add command to run tests in persistent mode
* Convert Suspense fuzz tester to use noop renderer
So we can run it in persistent mode, too.
* Don't mutate stateNode in appendAllChildren
We can't mutate the stateNode in appendAllChildren because the children
could be current.
This is a bit weird because now the child that we append is different
from the one on the fiber stateNode. I think this makes conceptual
sense, but I suspect this likely breaks an assumption in Fabric.
With this approach, we no longer need to clone to unhide the children,
so I removed those host config methods.
Fixes bug surfaced by fuzz tester. (The test case that failed was the
one that's already hard coded.)
* In persistent mode, disable test that reads a ref
Refs behave differently in persistent mode. I added a TODO to write
a persistent mode version of this test.
* Run persistent mode tests in CI
* test-persistent should skip files without noop
If a file doesn't reference react-noop-renderer, we shouldn't bother
running it in persistent mode, since the results will be identical to
the normal test run.
* Remove module constructor from placeholder tests
We don't need this now that we have the ability to run any test file in
either mutation or persistent mode.
* Revert "test-persistent should skip files without noop"
Seb objected to adding shelljs as a dep and I'm too lazy to worry about
Windows support so whatever I'll just revert this.
* Delete duplicate file
* Don't download bundle stats from master on CI
This was temporarily necessary in the past because we didn't have the logic that downloads actual *merge base* stats.
We do have that now as part of the Danger script. So we can remove this.
* Use absolute threshold for whether to show a change
* Download master stats, but only for other master builds
* Rewrite sizes
* Revert "Replace danger token with a refreshed facebook-open-source-bot token (#12295)"
This reverts commit 2d511479c4.
* Revert "Temporarily disable Danger in CI (#12291)"
This reverts commit 925fc93389.
* [Danger] Use the PR's mergebase for a branch in the dangerfile instead of
the root commit's parent.
* [Danger] Get the full history to find the merge base
* Adds danger_js with an initial rule for warning about large PRs
Signed-off-by: Anandaroop Roy <roop@artsymail.com>
* [WIP] Get the before and after for the build results
* [Dev] More work on the Dangerfile
* [Danger] Split the reports into sections based on their package
* Remove the --extract-errors on the circle build
* [Danger] Improve the lookup for previous -> current build to also include the environment
* Fix rebase
I'm running out of ideas to keep these commit messages entertaining. Thankfully this should keep the CI green and we can forget any of it ever happened.
* Move ReactFiberTreeReflection to react-reconciler/reflection #11659
* Use * for react-reconciler
We don't know the latest local version, and release script currently doesn't bump deps automatically.
* Remove unused field
* Use CommonJS in entry point for consistency
* Undo the CommonJS change
I didn't realize it would break the build.
* Record sizes
* Remove reconciler fixtures
They're unnecessary now that we run real tests on reconciler bundles.
* Add bundle linting and tests to the release script
- add yarn lint-build
- use yarn lint-build in circle ci build.sh
- add yarn lint-build, yarn test-prod, yarn test-build, and yarn test-build-prod to the realse script
* Improve readability of release test messages
* Run prettier
* Updating package versions for release 16.2.0
* Seperate bundle specific tests
- Moved the runYarnTask into utils since its being used two files now
- Uncomment out checks I mistakenly committed
* Revert a bunch of version bump changes
Mistakenly commited by release script
* .js for consistency
