* Remove LoadingResultGravatar ulfjack2018-07-25
| | | | | | | | | | | Instead, refactor the code to use TargetPatternPhaseValue exclusively. This removes the need to convert from TargetPatternPhaseValue to LoadingResult, and prepares for interleaving. It also reduces the number of Skyframe calls which may speed up null builds a bit, as a followup for https://github.com/bazelbuild/bazel/commit/1067310e18cb9ac203110726de0be53bdc403cea.

* remote: fix race on download error. Fixes #5047Gravatar buchgr2018-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | For downloading output files / directories we trigger all downloads concurrently and asynchronously in the background and after that wait for all downloads to finish. However, if a download failed we did not wait for the remaining downloads to finish but immediately started deleting partial downloads and continued with local execution of the action. That leads to two interesting bugs: * The cleanup procedure races with the downloads that are still in progress. As it tries to delete files and directories, new files and directories are created and that will often lead to "Directory not empty" errors as seen in #5047. * The clean up procedure does not detect the race, succeeds and subsequent local execution fails because not all files have been deleted. The solution is to always wait for all downloads to complete before entering the cleanup routine. Ideally we would also cancel all outstanding downloads, however, that's not as straightfoward as it seems. That is, the j.u.c.Future API does not provide a way to cancel a computation and also wait for that computation actually having determinated. So we'd need to introduce a separate mechanism to cancel downloads. RELNOTES: None PiperOrigin-RevId: 205980446

| | | | | | | | | | *** Reason for rollback *** Fixed duplicate derived inputs bug. Test is in diffbase. RELNOTES[INC]: If the same artifact is generated by two distinct but identical actions, and a downstream action has both those actions' outputs in its inputs, the artifact will now appear twice in the downstream action's inputs. If this causes problems in Skylark actions, you can use the uniquify=True argument in Args.add_args. PiperOrigin-RevId: 205863806

* Move LoadingPhaseCompleteEvent posting to TargetPatternPhaseFunctionGravatar ulfjack2018-07-24
| | | | | | | | | | | Also simplify LoadingPhaseCompleteEvent, and SkyframeExecutor, and remove LoadingCallback, which is unnecessary now that we only have a single implementation (previously LoadingPhaseRunner). This also removes some of the excessive Skyframe calls introduced by https://github.com/bazelbuild/bazel/commit/1067310e18cb9ac203110726de0be53bdc403cea, and prepares for interleaving target pattern eval and loading.

* Remove redundancy in DigestHashFunction use in FileSystem.Gravatar ccalvarin2018-07-23

* 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. PiperOrigin-RevId: 205634761
* 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.)
