* Reimplement blaze query using an async evaluation model. Use a concurrent ↵Gravatar Nathan Harmata2017-02-28
| | | | | | | | | | | | | | | | | | | backend for SkyQueryEnvironment's implementation in order to achieve parallelism. Advantages: -New design has no flaws that the old design had. -Code is structured so that deadlocks due to thread starvation are impossible (yup!). Disadvantages: -The meat of this change needs to all be in a single CL because every single QueryFunction and QueryExpression needs to be rewritten in the async style. Still TODO: -Fully embrace the async model in all QueryFunctions (e.g. 'rdeps', 'allpaths'). -Use concurrency in BlazeQueryEnvironment to achieve parallel evaluation for (non SkyQuery) 'blaze query' and genquery. -- PiperOrigin-RevId: 148690279 MOS_MIGRATED_REVID=148690279

| | | | | | | | | | | | | | | A target's tags and output files are reported as part of the TargetComplete event of the build event protocol (BEP).

* sandbox should create regular empty files, not symlink to /dev/null.Gravatar Philipp Wollermann2017-02-28
| | | | | | | | | | | | | | Adds a test based on our Python rules that makes sure that this actually fixes the issue. Thanks to @duggelz for the suggestion. It seems like our Python rules are the only place that actually provides an EmptyFilesSupplier to Runfiles, so there's probably no simpler way to test this behavior in an integration test. Fix #1458.

* Fix Cpp action cachingGravatar Ulf Adams2017-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This combines both previous changes and extends them to work both with and without kchodorow@'s rollout of the exec root rearrangement. Unfortunately, each of these changes individually breaks something somewhere, so they must all go into a single commit. Change 1: CppCompileAction must return false from inputsKnown for .d pruning This is necessary (but not sufficient) for the action cache to work correctly. Consider the following sequence of events: 1. action is executed 2. .d pruning is performed 3. action cache writes entry with post-pruning inputs list 4. action gets regenerated (e.g., due to server restart) 5. the action cache calls inputsKnown(), which returns true 6. action cache checks entry from step 3 against pre-pruning inputs list, which results in a cache miss The action cache needs to know that the current list is not the final list, so inputsKnown() in step 5 must return false if .d pruning is enabled. Change 2: Fix artifact root discovery for external artifacts The SkyframeExecutor was assuming that all exec paths were coming from the main repository. Instead, rely on external exec paths to start with "../". Additional change 3: In addition, update the PackageRootResolverWithEnvironment and the HeaderDiscovery to use the single unified repository name guessing implementation. Previously, the PackageRootResolverWithEnvironment was poisoning the source artifact cache, which then caused subsequent lookups to return a bad artifact. Add a precondition to double-check that artifacts looked up by exec path have the correct source root. For compatibility with kchodorow@'s upcoming exec root refactor, if the exec path starts with "external", then assume it's coming from an external repository. This must be removed when that change is successfully rolled out, or it will break if anyone creates a package called 'external'. Additional change 4: On top of all of that, PackageRootResolverWithEnvironment and SkyframeExecutor must use the same source root computation as the Package class itself. I extracted the corresponding code to Root, and added comments both there and in Package to clearly indicate that these methods have to always be modified in sync. Fixes #2490. -- PiperOrigin-RevId: 148439309 MOS_MIGRATED_REVID=148439309

| | | | | | | | | | | | | | | | | | | AbstractAction#getInputFilesForExtraAction(). Turns out, we didn't add *mandatory* inputs of the shadowed action to the extra action, thus, breakage. Original description: Remove AbstractAction#getInputFilesForExtraAction(). This method was used to return the discovered inputs for extra actions, but it turns out that we can use #discoverInputs() just as well. Note that this makes it possible for #discoverInputs() to be called more than once per action instance (once for the action and once for each extra action), but this appears to work. A followup change may be able to dispense with that, but let's take baby steps for now. Also note that this introduces synchronization between an action and its associated extra action. -- PiperOrigin-RevId: 148429641 MOS_MIGRATED_REVID=148429641
