* Add the ability to reconstruct a BuildOptions from the diff with another ↵Gravatar janakr2018-03-09
| | | | | | BuildOptions. Motivation is that the diffs are likely to be much smaller than the actual BuildOptions objects themselves, so in places we need a BuildOptions (I'm looking at you, BuildConfigurationValue.Key), we can instead store a diff, reconstructing the BuildOptions object itself on demand when needed.

* Improve the warning for malformed recursive configs.Gravatar ccalvarin2018-03-09
| | | | | | | | | Unlike in fixed-point (legacy) expansion of configs, with --expand_configs_in_place we do not use the options parser to parse each config-definition default override - we first find the full expansion and then expand it in place of the original --config=value instance. For this reason though, we don't support space-separation of recursive configs and their values. The old warning for this was confusing though, and did not provide much guidance. This should be better, now the warning specifies which config is malformed, in what file, and that it expects the "=" character. RELNOTES: None. PiperOrigin-RevId: 188509060

* Update cpp-use-cases.mdGravatar aolivas2018-03-09
| | | | | | | | | | | | | I wasn't able to build a simple 'hello-world' example with an identical structure. I encountered several problems: 1) bazel forces to declare a license for code within the 'third_party' sub-directory. This not at all obvious to noobs. 2) bazel complains about a missing input file 'some_lib.h' without the leading 'include' in hdrs and the build fails. 3) compilation throws "No such file or directory" when trying to include 'some_lib.h' with the trailing 'include' in copts. I think this is particularly important for converting legacy projects (not necessarily third party) that use cmake, autoconf, etc... Closes #4697. PiperOrigin-RevId: 188471650
* tests: fix flaky RecursiveFSTraversalFunctionTestGravatar Laszlo Csomor2018-03-09
| | | | | | | | | | | | | | | | | | Fix the testTraversalOfGeneratedDirectory method in RecursiveFilesystemTraversalFunctionTest that was flaky on Windows. The fix is to wait so that changes to files in the InMemoryFileSystem will have observable effects on the file ctimes. Depends on https://github.com/bazelbuild/bazel/pull/4787 Fixes https://github.com/bazelbuild/bazel/issues/4755 Closes #4788. PiperOrigin-RevId: 188470080

* Automated rollback of commit 3edf41b70de9bb1a8702d0342beeb2ad13898d71.Gravatar philwo2018-03-09
| | | | | | | | | | | | | | | | | | | | | *** Reason for rollback *** Rollback was requested by original authors @hmemcpy and @ittaiz in #3201: "We found a problem with this patch... seems that tests that are added dynamically by the test runner (in our case, specs2 'examples' that are generated with Fragments.foreach) do not appear in the xml!" This should be part of 0.12.0-rc1, otherwise that release will have the above mentioned regression. *** Original change description *** Skipping writing FILTERED tests to test.xml This fixes #3201 by preventing tests that haven't actually run to be written to the test.xml. This is consistent with how e.g. surefire reports work, tests that were filtered out do not appear in the xml. This allows changing the Bazel plugin in such a way that does not depend on `time` being 0.0. Closes #4596. PiperOrigin-RevId: 188455315
* runfiles,py,java: rlocation accepts absolute pathGravatar Laszlo Csomor2018-03-09
| | | | | | | | | | | | | | | | | | | | | The rlocation functions in the Python and Java runfiles libraries (under @bazel_tools//tools/runfiles) now consistently return the argument itself if it is an absolute path. If the argument is a driveless absolute Windows path (e.g. "\\windows\\system32") then rlocation reports an error. See https://github.com/bazelbuild/bazel/issues/4460 Change-Id: I80474f7cc4736a571bf113438a916f71c36a344d Closes #4806.

* Optimize GC churn of parameter bindings performed before each user defined ↵Gravatar nharmata2018-03-08
| | | | | | | | | | | | | | | function call. This is the 2nd attempt at this commit. The first attempt (https://github.com/bazelbuild/bazel/commit/f1013485d41efd8503f9d4f937e17d1b4bc91ed3) was rolled back because it introduced the following two bugs: (1) The side effects of Environment#enterScope are relevant: it creates and stores a new Continuation that has a reference to the set currently referenced by 'knownGlobalVariables', and then overwrites the value of the variable. When there are e.g. nested function calls, 'knownGlobalVariables' will be wrong in the Environment used to stage the inner call (see the added test for an example). (2) The finally block in UserDefinedFunction#call assumes the env.enterScope was called. Because of the EvalException (incorrectly) thrown due to (1), this is no longer true. I restructured the code such that (2) isn't possible and I also added a unit test that would have caught the two bugs. In my first attempt, I was doing too much - I was also trying to save the CPU-costs in the env.update call (dispatches to the just-created lexical frame, and calls LexicalFrame#put, which does an unnecessary mutability sanity check, etc) and in doing so completely missed the above bugs. Sorry. RELNOTES: None PiperOrigin-RevId: 188411737

* Add an interface to interact with sandboxfs.Gravatar jmmv2018-03-08
| | | | | | | | | | | | | | | | The new SandboxfsProcess interface allows interacting with sandboxfs. There are two implementations: RealSandboxfsProcess, which spawns the sandboxfs binary, and FakeSandboxfsProcess, which mimics what sandboxfs does but using symlinks and is intended for testing purposes only. The RealSandboxfsProcess implementation works but still carries many TODOs. The most "painful" one may be that the test requires manual invocation because we do not yet have an easy way to integrate with sandboxfs. That will be solved later on; for now this is sufficient for initial testing. RELNOTES: None. PiperOrigin-RevId: 188347393

* Fixed missing C standard library functions with NDK r15 and r16Gravatar jingwen2018-03-07
| | | | | | | | | Certain C++ stdlib wrapper headers are unable to find their C counterparts (e.g. math.h for cmath) that are in %ndk%/sysroot/usr/include. This is because the -isystem for the include path was added with addCompilerFlag instead of addUnfilteredCxxFlag. The former is filtered out when compiling C code, whereas the latter keeps it.
