* Add --experimental_enable_cc_toolchain_label_from_crosstool_proto flag for ↵Gravatar rosica2018-07-23
| | | | | | | | | disabling relying on CROSSTOOL file in order to select the cc_toolchain label CROSSTOOL file should not have any influence over selection of the cc_toolchain label. Ultimately the information that CROSSTOOL offers will be rerouted through an attribute of cc_toolchain. RELNOTES: None. PiperOrigin-RevId: 205651369

* Suppress RepositoryCache IOException on downloadGravatar George Gensure2018-07-23
| | | | | | | | | | | | | | With invalid contents in the repository cache, silence the IOException on RepositoryCache::get and re-download an artifact when attempting to short-circuit that operation. The repository cache can easily get into this state when a build is interrupted while downloading into the non- atomic repository cache destination. Possible solution to #5390 Closes #5392.

* Remove PerActionFileCacheGravatar ulfjack2018-07-23
| | | | | | | | | | | | | Instead, make ActionMetadataHandler implement the MetadataProvider interface. This fixes an issue where an action that runs two spawns where one depends on an output of the other was unable to get the metadata for the intermediate output. We don't currently have actions that do this, but we will have in a future change (which will also implicitly act as a regression test). PiperOrigin-RevId: 205629237

* Move --linkopt flags into user_link_flagsGravatar hlopko2018-07-19
| | | | | | | | | | | | | | | | Previous behavior was to put flags coming from Bazel option --linkopt into legacy_link_flags. They should be in user_link_flags instead (together with flags coming from linkopts rule attribute). This cl introduces --experimental_linkopts_in_user_link_flags option that flips the behavior. There is another incompatible change. Previously cc_common.create_link_variables() included flags from --linkopt, with the flag flipped it doesn't anymore. I believe --linkopt flags shouldn't be there by default because: * We don't tie the API with the specifics of C++ rules/options, enabling theoretical use with other languages (objc) * Users are free to use ctx.fragments.cpp to access C++ options and add them explicitly (https://github.com/bazelbuild/bazel/issues/5602) * New behavior maintains the symmetry with --copt and user_compile_flags RELNOTES: None.

* When applying an aspect to a generated file of a Fileset avoid creating the ↵Gravatar lpino2018-07-18
| | | | | | | | FilesetEntryMap for the aspect's RuleContext. The current logic in createFilesetEntryMap() uses the rule of the RuleContext.Builder to determine whether to create a filesetEntryMap or not, because of this, applying an aspect to a generated file of a fileset (e.g. 'out' attribute of a Fileset) causes createFilesetEntryMap to create the map even though the associated target is, for instance, a generated file. As a consequence, applying any aspect to a generated file of a fileset causes a NullPointerException. PiperOrigin-RevId: 205065778

* Android NDK r17 supportGravatar Jingwen Chen2018-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Full NDK changelog](https://github.com/android-ndk/ndk/wiki/Changelog-r17) Changes related to Bazel's NDK toolchain/CROSSTOOL generation: - Removed support for targeting mips, mips64, armeabi. - Bumped bundled clang version to 6.0.2. - The default STL is now libc++. If Bazel detects that r17 is being used, it aliases `@androidndk//:default_toolchain` to `@androidndk//:toolchain-libcpp`, instead of `@androidndk//:toolchain-gnu-libstdcpp`. - Removed tests that build against armeabi, mips, mips64. - Stop passing `-fno-integrated-as` into the compiler by default. TODO: - [x] Java tests - [x] ~Support for wrap.sh to use with ASANs~ Implementing in follow up PR. - [ ] Fix or disable remote caching with android_ndk_integration_test https://github.com/bazelbuild/bazel/issues/4663 Fixes https://github.com/bazelbuild/bazel/issues/4742 RELNOTES: Added support for Android NDK r17. The default STL is now `libc++`, and support for targeting `mips`, `mips64` and `ARMv5` (`armeabi`) has been removed. Closes #5371.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | range used to use MutableList which would eagerly allocate an array list with all range elements, which is not efficient for very large ranges or when only a small number of its elements are used. This implementation uses a constant amount of RAM and computes a value for each requested index. For the following Skylark snippet: ``` def check_content(t): if t == []: return t return False def modulo(n): return n % 797 N = 10000000 [check_content(i) for i in range(N)] [check_content(i) for i in range(N)] [modulo(i) for i in range(N)] [modulo(i) for i in range(N)] ``` the total runtime goes from ``` $ time bazel-bin/src/main/java/com/google/devtools/skylark/Skylark test.bzl bazel-bin/src/main/java/com/google/devtools/skylark/Skylark test.bzl 93.09s user 1.67s system 316% cpu 29.930 total ``` to ``` $ time bazel-bin/src/main/java/com/google/devtools/skylark/Skylark test.bzl bazel-bin/src/main/java/com/google/devtools/skylark/Skylark test.bzl 31.45s user 0.86s system 179% cpu 17.974 total ``` which reflects the reduced system time (fewer allocations) and performance.

* Ensure BEP file output stream is flushed promptly.Gravatar Googler2018-07-16
| | | | | | | | | | | | | | | | | | Tulsi uses BEP json output in its UI, to simulate Bazel terminal outptut. This means we have to promptly flush the stream. It's sufficient to do flushing at the granularity of whole events, not any specific count of bytes, since whole events are what's being consumed by the user. To balance IO throughput and interactivity, let's flush at a regular sub-second interval. (The alternative solution of using a stream with smaller buffer could still end up with small-sized event descriptions buffered arbitrarily long; and abandoning buffering altogether would be suboptimal for throughput when writing a long sequence of small build events.)

* remote: add a ByteStreamBuildEventArtifactUploaderGravatar buchgr2018-07-12
| | | | | | | | | | | | | | | This change allows local files referenced by the BEP/BES protocol to be uploaded to a ByteStream gRPC service. The ByteStreamUploader is now implicitly also used by the BES module which has a different lifecycle than the remote module. We introduce reference counting to ensure that the channel is closed after its no longer needed. This also fixes a bug where we currently leak one socket per remote build until the Bazel server is shut down. RELNOTES: None PiperOrigin-RevId: 204275316

This will make it easier and less error-prone to add additional state to the provider. PiperOrigin-RevId: 204258844
* Set the version of a computed node to the max of its child versions rather ↵Gravatar janakr2018-07-11
| | | | | | | | | | | | | | | | | than the graph version when that is feasible. * It's not feasible when the computation accesses outside state, i.e. is non-hermetic, so see below. * It's also more complicated (and not worth the trouble) when the computation is taking place just for the error status. Have SkyFunctionName declare whether the function it corresponds to is hermetic or non-hermetic. Only non-hermetically-generated SkyValues can be directly marked changed, and non-hermetic SkyFunctions have their values saved at the graph version, not the max of the child versions. All SkyFunctions are hermetic except for the ones that can be explicitly dirtied. A marked-hermetic SkyFunction that has a transient error due to filesystem access can be re-evaluated and get the correct version: if it throws an IOException at version 1 and then, when re-evaluated at version 2 with unchanged dependencies, has a value, the version will be version 1. All Skyframe unit tests that were doing non-hermetic things to nodes need to declare that those nodes are non-hermetic. I tried to make the minimal set of changes there, so that we had good incidental coverage of hermetic+non-hermetic nodes. Also did some drive-by clean-ups around that code. Artifacts are a weird case, since they're doing untracked filesystem access (for source directories). Using max(child versions) for them gives rise to the following correctness bug: 1. do a build at v1 that creates a FileStateValue for dir/ at v1. Then at v2, add a file to dir/ and do a build that consumes dir/ as a source artifact. Now the artifact for dir/ will (incorrectly) have v1. Then at v1, do that build again. We'll consume the "artifact from the future". However, this can only have an effect when using the local action cache, since the incorrect value of the artifact (the mtime) is only consumed by the action cache. Bazel is already broken in this way (incremental builds don't invalidate directories), so this change doesn't make things worse. PiperOrigin-RevId: 204210719
* Make the FileArtifactvalue of generated targets available via the ↵Gravatar kush2018-07-11
| | | | | | | | | | | | | | FilesetOutputSymlink whenever available. In this change I'm simply plumbing the FileArtifactValue we requested within RecursiveFilesystemTraversalFunction to the FilesetOutputSymlink. This does not work when the targets are output directories (or symlink to output dirs). The main scenarios this happens is when: 1. Fileset depends on the output dir created by a genrule. 2. Fileset depends on a GoAppengineBinary which creates an output dir. 3. Fileset depends on another Fileset in the non-recommended way (Fileset.entry.files = [<another_fileset>]) instead of the recommended way (FilesetEntry.srcdir = <another_fileset>).
