* Support multiple command lines / params files in SpawnAction.Gravatar tomlu2017-09-15
| | | | | | This is necessary for the upcoming Skylark implementation of param files. PiperOrigin-RevId: 168744486
* Add whitelists for android_resources removalGravatar Googler2017-09-15
| | | | | | | Add additional tooling for removing android_resources RELNOTES: none PiperOrigin-RevId: 168741510
* Add serialization support to BlazeDirectories (and .hashCode() and .equals() ↵Gravatar janakr2017-09-15
| | | | | | | | support into the bargain). Equality checking isn't that important since there's only one instance per Blaze server, but it keeps serialization semantics reasonable. PiperOrigin-RevId: 168735669
* Do not flatten resource artifacts in Android rules.Gravatar tomlu2017-09-15
| | | | | | This involves rather tediously rolling up each artifact type in its own individual nested set. PiperOrigin-RevId: 168729120
* Use top-level targets' configurations for convenience symlinks.Gravatar mstaib2017-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new flag, --use_top_level_targets_for_symlinks. Configuration-specific convenience symlinks (i.e., (prefix)bin, (prefix)genfiles, (prefix)testlogs) previously pointed at the one top-level target configuration. If there were multiple top-level target configurations, which could only happen when --experimental_multi_cpu was used, then no symlinks would be created, though they would not be deleted either. With the flag on, the output directories of the configurations actually used by the top-level targets (after rule class transitions etc.) are compared. If all targets with non-null configurations have the same configuration (or, more specifically, if all targets with non-null configurations have configurations with the same output directory), then a symlink is created pointing at it. Otherwise, the symlink is deleted, to avoid confusion with stale symlinks from old builds. Known changes in behavior WITHOUT the flag turned on: * In the --experimental_multi_cpu case, non-configuration-specific convenience symlinks (i.e., (prefix)(workspace) and (prefix)out) will always be created, even though they previously wouldn't have been created at all in this case. (should be harmless) * In the --experimental_multi_cpu case, configuration-specific convenience symlinks will be created if all configs have the same output directory. (should be safe, or specifically, should never happen because multi-cpu would necessarily change the output path, but shouldn't hurt anything even if it did) * In the --experimental_multi_cpu case, configuration-based convenience symlinks will be deleted if some configs have a different output directory. (slightly more noticeable since that will be every build using experimental_multi_cpu, but then, it is experimental) RELNOTES: None. PiperOrigin-RevId: 168720843

* Only compute hostname once per server lifetimeGravatar hlopko2017-09-14
| | | | | | | | | | | | NetUtil.getShortHostName can take seconds on mac and on windows (like, 20!), since it performs reverse dns lookup. We already cached hostname for the BazelWorkspaceStatusModule, let's cache it for entire bazel server. Also make sure that users of the method understand it's cached. Fixes #3586. RELNOTES: None.

* Pass the UnparsedOptionValues when setting or adding option values.Gravatar ccalvarin2017-09-14
| | | | | | | | Stop breaking the value apart to be recombined later. Also stop using OptionValueDescriptions as though we have a final option when expanding flags for invocation policy. These values are explicitly the output from parsing the expansion strings, not yet converted or combined with other values of the same flag. After this change, only UnparsedOptionValueDescription should be used when strings of flags are parsed, and OptionValueDescription should be used when the final version of a flag is created or used. PiperOrigin-RevId: 168688063
* Implemented a check for implicitly-exported deps in android_library, and ↵Gravatar jingwen2017-09-14
| | | | | | | | | raise a warning/error depending on --experimental_allow_android_library_deps_without_srcs (defaulted to true for a warning). Previously, users of generated android_library rules with this specific attribute combination do not see the warning message because the message comes from a Skylark macro. Once this is in, users having such a rule (even in their transitive, generated dependencies) will see the warning message. RELNOTES: Deprecated: Using the android_library.deps attribute to implicitly export targets to dependent rules. If your code is using this feature, Bazel will raise a warning. To fix, please use android_library.exports to explicitly specify exported targets. Run with --experimental_allow_android_library_deps_without_srcs=false to ensure forward compatibility when this feature is removed in a future release. PiperOrigin-RevId: 168686765

* Consolidate the "unparsed" option value tracking.Gravatar ccalvarin2017-09-14
| | | | | | | In preparation for linking the parsed and unparsed values of options, consolidate and standardize our representation of the flag values as we received them (what is meant by "unparsed" values in this case). This was being done separately in ParseOptionResult, which, with extra context added, is being folded into UnparsedOptionValueDescription. We now track how an option was provided and where it came from for all option parsing. RELNOTES: None. PiperOrigin-RevId: 168682082
* bep: Properly URI encode file pathsGravatar buchgr2017-09-14
| | | | | | RELNOTES: The Build Event Protocol's File.uri field is now properly encoded according to RFC2396. PiperOrigin-RevId: 168674865
* Introduce -c source_file -o output_file build variablesGravatar hlopko2017-09-14
| | | | | | | | | | | | Prior to this cl CompileCommandLine would (almost) unconditionally emit -c and -o flags. This cl removes this logic and relies on crosstool to emit these flags. This is another small step towards platform independent C++ rules. Memory use is not affected, since the build variables used by this cl are already exposed, this cl just forces crosstools to use it. RELNOTES: None. PiperOrigin-RevId: 168671507
* Windows: Adding default --python_pathGravatar Yun Peng2017-09-14
| | | | | | | | | | | On Windows, Bazel client will try to find python.exe in $PATH. If succeed, then we pretend to add a --python_path option in the least important bazelrc file.

* Introduce empty "toolchain_category" rule for labels that will be used asGravatar cpeyser2017-09-14
| | | | | | | | categories of toolchains for the purpose of toolchain selection. Up to now, we've used the native toolchain_type rule for this purpose. That rule depends on a number of configuration fragments that supply build variables - we don't want toolchains to need to depend on those fragments as well. E.g. toolchain_type depends on JvmConfiguration, but we would like toolchains to work with --experimental_disable_jvm. PiperOrigin-RevId: 168577759
* Adds the command line report protocol.Gravatar ccalvarin2017-09-14
| | | | | | | | This will be used by tools to pass Bazel their command lines, and by Bazel to report its command line(s) via the build event stream. See https://bazel.build/designs/2017/07/13/improved-command-line-reporting.html for additional context on why this is useful. This proto is intentionally vague about certain details of the command line, in order to be accommodating of future changes. However, it needs to be specific enough that it is very clear how a command line would be broken up into the different types of sections. PiperOrigin-RevId: 168576969

* Move option value tracking classes to their own file.Gravatar ccalvarin2017-09-13
| | | | | | | These classes are mostly used during the options parsing process itself, and are barely a part of the options parser interface, so they really don't belong in OptionsParser.java. They are also about to change significantly, so taking this opportunity to split them out. RELNOTES: None. PiperOrigin-RevId: 168400162

Ensure that even in this case the steam of build events is internally closed (i.e., all announced events are reported, the last event is marked as such).

* bes: cancel stream on bazel shutdownGravatar buchgr2017-09-12
| | | | | | | | | | | | | | | | | Introduce a new method BuildEventTransport#closeNow() which forcefully closes the BES upload even if there are still events to upload. This is executed if the bazel server is being shutdown. The implementation in the BuildEventServiceTransport works by shutting down the ExecutorService handling the upload, which in turn will interrupt the upload thread, which in turn will cancel the streaming RPC. The BuildEventServiceTransport will wait up to 100ms for that cancellation to happen. Also fix a bug where the BES transport would not wait for ACKS. PiperOrigin-RevId: 168359947

* Merging a RunfilesSupport object into Runfiles.Builder no longer adds the ↵Gravatar Benjamin Peterson2017-09-12
| | | | | | | | | | | | | | | | | | | | | | runfiles middleman to the artifacts. Runfiles.Builder.merge(RunfilesSupport) would add the runfiles middleman of the RunfilesSupport object being merged into the artifacts of the nascent Runfiles object. This effectively made the construction of one runfiles tree depend on that of another. Instead of putting the runfiles middleman into the runfiles artifacts, we can put it into the FilesToRunProvider, which should have the same effect. To facilitate this, RuleConfiguredTargetBuilder gains a addFilesToRun method. Note that not every caller of merge(RunfilesSupport) has to be modified because some were already adding the runfiles middleman to their FilesProvider (e.g., AndroidHostServiceFixture), which is a subset of FilesToRunProvider. This is split out from https://bazel-review.googlesource.com/c/14010 Change-Id: Icfca5262a32619e1e351477f3ff641350b6798dc PiperOrigin-RevId: 168358030
* remote: Add new retrier with support for circuit breakingGravatar buchgr2017-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | Add a generic retrier implementation (Retrier2) that can be configured by plugging in a backoff strategy, a function to decide on retriable errors and a circuit breaker. A concrete implementation is added via RemoteRetrier that mostly is a copy of the code of the existing Retrier. Retrier2 adds support for circuit breaking [1]. It allows the retrier to reject execution when failure rates are high. The remote execution code will use this to gently switch between local and remote execution/caching if the latter experiences lots of failures. Retrier2 is also useful when not used with gRPC. We need retriers for the HTTP caching interface too. All the code added in this CL is unused, to keep reviews managable. In a follow up CL, I will switch the code to use the new Retrier and delete the old retrier. [1] https://martinfowler.com/bliki/CircuitBreaker.html PiperOrigin-RevId: 168355597

| | | | | | | | | This cl removes hardcoded --sysroot flag generation from bazel when constructing command line for C++ actions. The hardcoded flag is still exposed to Skylark (to stay backwards compatible). RELNOTES: None. PiperOrigin-RevId: 168346711
