* Remove feature to allow expansion flags to have values.Gravatar ccalvarin2017-10-18
| | | | | | | | | It was added as a potential fix for --config (an expansion flag with values), but this would have required forcing the parser to know the config's expansions at parsing time, which is not currently possible. Instead, we will use the new addition of option-location tracking to make sure we expand options at a the correct place, even if the expansion is triggered after the fact. This is mostly a straight forward undoing of https://github.com/bazelbuild/bazel/commit/7c7255ec8d6da20526c2c4078c57aadaf3dd3612, except where the context has changed. Notably, implicit requirements are effectively treated like expansion flags, so special casing in OptionDescription could be removed. RELNOTES: None. PiperOrigin-RevId: 172514997

* Make cc_toolchain put the files comprising the toolchain into its FileProvider.Gravatar lberki2017-10-18
| | | | | | | Note that cc_toolchain_suite is not changed this way, but that rule doesn't currently serve as a proxy for cc_toolchain (unlike java_runtime_suite for java_runtime), so that's OK. RELNOTES: None. PiperOrigin-RevId: 172502279

| | | | | | | | | | | | | | The previous regex was only matching lines and was not even correctly doing so. We no match everything that is starting with none, n/a or no as a sentence or as a full line. We also match empty string and '.' as a full line. RELNOTES: . RELNOTES: None.

* Only run cpp_darwin_integration_test on darwinGravatar hlopko2017-10-18
| | | | | | | | | | | | This test assumes linking and loading behavior only present on darwin, it doesn't make sense to run this test on other platforms. But our CI does. This cl makes the test pass without executing anythign when run on a non-darwin platform.

* Skylint: don't warn for unused initialization with 'None'.Gravatar fzaiser2017-10-18
| | | | | | | | | | | | | | | | | | | | It's good practice to place a "declaration" of a variable in a location that dominates all its uses, especially so if you want to document the variable. Hence we want no warning saying this declaration is unused. Example: var = None # don't warn about the unused declaration here if condition: var = 0 else: var = 1 As noted in the code, this also has the undesired side-effect of suppressing the warning here: var = None # doesn't warn either but ideally should var = 0 Fixing the latter problem is not worth the increased code complexity, in my opinion.

* build_windows_jni: fix @cd callGravatar Laszlo Csomor2017-10-18
| | | | | | | | | | | | In cmd.exe it's not enough to `cd` into a directory to change the shell's current working directory: you also have to change to the right drive.

* Stream rest cache file uploads.Gravatar Benjamin Peterson2017-10-18
| | | | | | | | | | | | | | | This means we no longer keep large action inputs or outputs in memory during upload. I adjusted the SimpleBlogStore interface to require clients to pass in the InputStream length. That allows us to always set Content-length on uploads. It's polite to do so, so that the server may, e.g., preallocate space for the blob. Fixes https://github.com/bazelbuild/bazel/issues/3250.

* Remove the target_apple_env and the apple_host_system_env methods from ↵Gravatar lberki2017-10-18
| | | | | | | | | | ctx.fragments.apple . Progress towards #3424. RELNOTES[INC]: the target_apple_env and apple_host_system_env methods on ctx.fragments.apple are not supported anymore. The same information is accessible through apple_common.target_apple_env and apple_common.apple_host_system_env . They need the Xcode configuration as an argument, which can be obtained by declaring an implicit dependency on it (i.e. attr.label(default=Label("@bazel_tools//tools/osx:current_xcode_config")) and then calling e.g. apple_common.apple_host_system_env(ctx.attr._xcode_config[apple_common.XcodeVersionConfig]).

* Track Option placement within a priority category.Gravatar ccalvarin2017-10-18
| | | | | | | | | An option has precedence over previous options at the same enum-valued priority. Track its placement in this ordering explicitly. This will allow after-the-fact expansion of expansion options such that they correctly take precedence or not compared to other mentions of the same flag. This is needed to fix --config's expansion.

* Optimize trusted MutableList constructionGravatar michajlo2017-10-18
| | | | | | | | | | | | Cuts back a lot of unnecessary copying. All construction is funneled through copyOf and wrapUnsafe. copyOf is the traditional construction mechanism, taking defensive copies of the input and determining if GlobList information needs to be retained. wrapUnsafe takes full ownership of the supplied ArrayList, allowing us to skip a lot of copies in trusted situations. This is particularly useful for common built in functions which return a list, range() being one common example. RELNOTES: None PiperOrigin-RevId: 172361367
* Delayed rollforward of commit 8fb311b4dced234b2f799c16c7d08148619f4087.Gravatar kush2017-10-18
| | | | | | | | | | | | | | | This was rolled back due to Tensorflow breakage but the patch I exported to gerrit (https://bazel-review.googlesource.com/c/bazel/+/18590) passed Tensorflow (https://ci.bazel.io/job/bazel/job/presubmit/52/Downstream_projects/). Confirmed with jcater@ that the "newly failing" projects in the Global Tests are known issues. I think we can check this in now. Additionally I had attempted to reproduce any tensorflow issues with this by building and testing TensorFlow locally with this patch, and all tests which passed with the released bazel had also passed with this patch. ================= Original change description ========================== Reinstate idleness checks where the server self-terminates when it's idle and there is either too much memory pressure or the workspace directory is gone. Arguably, it should kill itself when the workspace directory is gone regardless of whether it's idle or not, but let's first get us back to a known good state, then we can think about improvements.

* Windows: genenrate a fake CROSSTOOL when VC not foundGravatar Yun Peng2017-10-18
| | | | | | | | | | | | | | | | When Visual C++ build tools are not found on Windows, we generating a fake CROSSTOOL so that users can still build for other languages. In the fake CROSSTOOL, we point all tools to a batch script which prints error messages to notify users when they try to build any cc targets. Also, added an extra default_toolchain specification for x64_windows cpu value, so that users can use this cpu in select on non-Windows platforms.

* Accept command lines from tools invoking Bazel.Gravatar ccalvarin2017-10-18
| | | | | | | | | | | For tools that wrap Bazel in some way, the original way that the tool was invoked can be a useful piece of information to track when logging what Bazel did and why. In order to output this information in the same way that Bazel outputs its command lines, we accept --tool_command_line in the structure command line format that Bazel uses in the BEP. These structured command lines are protos that we expect as a base64 encoded byte array. For simple scripts that wish to use this feature without compiling the proto, we will also accept any old string (that cannot be interpreted as a base64 encoding) as a single "chunk" in a structured command line. This is experimental for now and users should not get attached to the format. We will remove the experimental_ prefix when it is stable. RELNOTES: None. PiperOrigin-RevId: 172341216
* Make tests independent of the default value for --experimental_uiGravatar Klaus Aehlig2017-10-18
| | | | | | | | | In preparation of experimental UI becoming the default UI for bazel, change some tests that depend on specifics of the current UI to explicitly specify the UI to use. Change-Id: If976c3eccd19c4a523c7eb1b4c4355ab2e5f9371 PiperOrigin-RevId: 172340189

* Actions now have a temp envvar.Gravatar László Csomor2017-10-16
| | | | | | | | | | | | | | | | | | | | | Every build and test action that creates a Spawn will now have platform-specific environment variables for temp directories: - on Windows: TMP and TEMP - on Linux/Darwin: TMPDIR This is particularly important on Windows where e.g. Java programs cannot create temp directories unless there's a valid TMP or TEMP environment variable set.

* BuildEventStreamer: clear a pending BuildStarted event firstGravatar Klaus Aehlig2017-10-16
| | | | | | | | | | | | | | | | | | | | If we receive an event indicating that the build is over, we first post that event and then clear up all pending event by stating that their prerequisite event was aborted (which we can safely assert, as we know we will not process any further events). Now, if a build is aborted (e.g., user interruption) before the build starting event is generated, the streamer can receive a build-finished event while still having an event (e.g., the raw command line) blocked on the build-starting event. So the canonical order of clearing the stream would send a build-finished event before the build-starting event, which can be confusing to consumers of the stream. Therefore, if have to generate an artificial aborted build-starting event, do so first (including clearing the events blocked on the build-starting event) and only afterwards post the build-finished event in the stream.

* BEP: explicitly report failures associated with a label as suchGravatar Klaus Aehlig2017-10-16
| | | | | | | | | | There is a conceptual difference between the (maybe unsuccessful) completion of a top-level target and a label as the root cause for a failure (i.e., a missing source file).
