* Dynamic transitions for controlling resource filteringGravatar Googler2017-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Dynamically Configured Resource Filtering change 4/6 Add dynamic transitions for controlling resource filtering. These transitions will be called in the next few reviews. Specifically, one transition turns dynamically configured resource filtering on, and updates the dynamically passed resource filter to contain the current target's resource filtering settings. The other turns off dynamic filtering, including removing all filtering settings and transitioning to FilterBehavior.FILTER_IN_ANALYSIS. We apply the appropriate transition in getTopLevelPatchTransition: if dynamic filtering was not requested, no transition is made; if dynamic filtering was requested but would not be appropriate (either because multiple top-level targets would mean dynamic configuration would probably split the build graph, or because no resource filters were provided so dynamically propagating them would be a waste of time) we transition to static filtering, and, otherwise, we continue to use dynamic filtering but preserve the current target's filtering settings so they can be passed to its dependencies. These transitions will actually be called in the next review. RELNOTES: none PiperOrigin-RevId: 162209042

* Extend the SpawnRunner APIGravatar ulfjack2017-07-17
| | | | | | | | | | | | | - add an id for logging; this allows us to correlate log entries for the same spawn from multiple spawn runner implementations in the future - add a prefetch method to the SpawnExecutionPolicy; better than relying on the ActionInputPrefetcher being injected in the constructor - add a name parameter to the report method; this is in preparation for a single unified SpawnStrategy implementation - it's basically the last bit of difference between SandboxStrategy and RemoteSpawnStrategy; they're otherwise equivalent (if not identical) PiperOrigin-RevId: 162194684
* AndroidBusyBox: deprecate path-list-type flagsGravatar laszlocsomor2017-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit: - deprecates PathListConverter - removes ExistingPathListConverter because it was not used in production, only tests - deprecated List<Path> type flags that use PathListConverter - introduces new List<Path> type flags next to the deprecated ones that use @Options.allowMultiple and convert with PathConverter; the new and old lists are concatenated, yielding the flag value PathListConverter and all of its occurrences should be removed after 2018-01-31 (about 6 months from now, which is a safe enough timeframe for everyone to upgrade Bazel so it uses the new-style flags). Reason for deprecation is that colon-separated path lists don't work on Windows because paths have colons in them. Since the Android BusyBox is not intended to be executed by users but by Bazel only, there's no release notes necessary.

* remote: Lower the chances of a race condition in the remote upload.Gravatar Ola Rozenfeld2017-07-17
| | | | | | | | | | | | Lower the chances of triggering #3360. Immediately before uploading output artifacts, check if any of the inputs ctime changed, and if so don't upload the outputs to the remote cache. I profiled the runs on //src:bazel before vs. after the change; as expected, the number of VFS_STAT increases by a factor of 180% (!), but, according to the profiler, it adds less than 1ms to the overall build time of 130s.

* ResourceFilter supports dynamically configured resource filteringGravatar Googler2017-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dynamically Configured Resource Filtering change 3/6 Resource filtering behaves somewhat differently when dynamically configured. Resources obtained from dependencies will have already been filtered and do not need to be filtered again. Resources that were filtered out do not need to be tracked since resource processing will never receive a reference to them anyway. Also, to make builds where ResourceFilter is dynamically configured, add equals and hashCode methods (otherwise, the configuration code throws a NullPointerException) and a global output prefix (otherwise, conflicts can occur). To ensure that the global output prefix (and the ResourceFilter object itself) is the same regardless of the ordering of filters in the android_binary, build the filters into a set, not a list, and sort them as part of creating the ResourceFilter object. This way, for example, objects built with filters "en,fr", "fr,en", and "en,en,fr" will all end up equal. Finally, rename the getFilteredResources method to better reflect its new role, and improve the isPrefiltering method to not try to prefilter if there are no filters. Add tests for all of this, and helper methods for all of those tests, including, most notably, a makeResourceFilter method that instantiates a ResourceFilter similarly to how it is actually created outside of tests (rather than directly calling the constructor) and a fake implementation of AttributeMap to support this.

* Filter LocalResourceContainer and use it to get a filtered ResourceContainerGravatar Googler2017-07-17
| | | | | | | | | | | | | | | | | | | | | | | Dynamically Configured Resource Filtering change 2/6 We need to filter LocalResourceContainer for dynamically configured resource filtering - it is an input to resource parsing for android_library targets. Filter it appropriately. Once it's being filtered, use it to build a filtered ResourceContainer, rather than building an unfiltered ResourceContainer and then filtering it. This means filtering gets done sooner, saving a bit of time and work, and isn't done twice, which would just be bad. To do this, we pass an unbuilt ResourceContainer.Builder into createApk, rather than a fully built one. Move the setAssetsAndResourcesFrom and setManifest calls to that builder, called every time, into createApk so that we only call them once. Also, initialize the ResourceFilter object when it's needed, rather than pass it down from the binary or library. This makes the code a bit cleaner, plus means library targets will pick up the dynamically configured information once that exists. RELNOTES: none PiperOrigin-RevId: 162007885
* Merge handleOptions into beforeCommandGravatar ulfjack2017-07-17

* Add new type descriptions for rule attribute documentation.Gravatar gregce2017-07-17

* Add the option filter enums in java, with equivalence check.Gravatar ccalvarin2017-07-17
| | | | | | | | | | In order to break out the proto dependency of the OptionsParser, add a java-only enum that users of the options parser can depend on, instead of requiring the dependency on the protobuf. The protocol buffer definition is kept in order to be used for command line reporting in the BEP, so a test is added to make sure that the two are kept in sync. Also add some clearer guidance for how to go about selecting, and adding, option categories and tags. Migrating the current uses of the proto enum to this one will happen in a follow-up change.

* Clean up string representations for unknown objectsGravatar vladmos2017-07-17

* Simplify exception handling in spawn strategiesGravatar ulfjack2017-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | The main change here is to only catch SpawnExecException in StandaloneTestStrategy, so all other exceptions simplify propagate up. As a result, Bazel no longer retries tests that fail with an exception, we only retry tests that actually ran, had a spawn result, and resulted in a UserExecException. That is probably what we want. Also do some cleanup: - Remove ExecException.timedOut; nobody was calling it (but there's still SpawnExecException.timedOut) - Remove SpawnActionContext.shouldPropagateExecException; all exceptions (except SpawnExecException) are now propagated by default - Remote the SandboxOptions from the SandboxStrategies; all sandboxing options are now handled by the underlying SpawnRunner implementations I'll send a followup CL to remove the UserExecException and EnvironmentalExecException types; the types don't do anything special, and there are no catch blocks in production code that catch one of these more specific types. This should fix #3322 by removing a bunch of special handling. PiperOrigin-RevId: 161960919

* CustomCommandLine.Builder: clean up its interfaceGravatar laszlocsomor2017-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this commit: - remove unused methods and classes - turn CustomCommandLine.ArgvFragment into an interface - remove the CustomCommandLine.TreeFileArtifactArgvFragment abstract class; it only had one remaining subclass - add @Nullable annotations where nulls are fine - add Precondition checks for non-nullable args - simplify the interface by removing add* methods that can be composed of other add* methods; this makes it easier to see what the callers do with the Builder - remove add* methods that add a single argument followed by a list of other elements (or a joined string of them); these had a bug in that they didn't check if the collection was empty (only that it was not null), and if it was empty then the single argument was still added though it was not followed by any value - fix call sites of add* methods where we previously could have added a flag with an empty collection - audit every affected call site RELNOTES: none PiperOrigin-RevId: 161957521

* Add link options from feature config to the Go link lineGravatar Googler2017-07-14
| | | | | | | | | | The C++ link for Go links involving C++ objects did not add linker options from feature configurations in the crosstool to the link line. This caused failures in go_test links when linking with LIPO, since a recent change moved the necessary link options to the crosstool feature config (e.g. unknown commit), instead of explicitly specifying them for the tests. This issue affected other link types as well (I confirmed that an --fdo_instrument link of a go_binary failed because it did not pick up the necessary link options from the feature config).

* experimental UI: keep console updated till the endGravatar Klaus Aehlig2017-07-14
| | | | | | | | | | | | | | | | For commands that do not send a BuildFinishedEvent, we normally use the NoBuildEvent to determine the end of the build and hence the moment where the UI should not any more interfere with the output. For some requests, like fetch, however, we should continue to report progress till the very end (as there is no output to interfere with). Do so, and also be sure that the experimental UI also reports downloads if not explicitly in a loading or analysis phase. While there, also group digits in the number of downloaded bytes, to increase readability. Change-Id: I31efeee5bdb1d29b2ecf842acb3e383e297707f8 PiperOrigin-RevId: 161935456
* experimentalUI: agressively bufferGravatar Klaus Aehlig2017-07-14
| | | | | | | | | | | | | | | | | To update the progress bar, we first have to remove it and then write the new one. For this to look smooth, the control sequence removing the old progress bar and the characters of the new progress bar have to arrive "in one go" at the (actual) terminal. As AnsiTerminal sends each control sequence as a separate write to the underlying stream, we have to buffer the underlying stream. Therefore, if the experimental UI is used, buffer that stream unconditionally until flushed, and not by line. For the experimental UI this is save, as it flushes the stream appropriately. For the old UI, we keep the line buffering, as the old UI relies on an implicit flush whenever a new-line character is written.

| | | | | | | | | | The Chunker should only open a file on the first call to next().

That's because on creating a new Chunker object it would already open a file, eventhough the first call to next would happen at a much later stage. PiperOrigin-RevId: 161923568
