* Actions now have the option of returning an ActionResult, containing a ↵Gravatar ruperts2017-10-18

* 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
* Fall back on basic StringCodec if FastStringCodec isn't availableGravatar michajlo2017-10-18
| | | | | | | Also adds a method which can be used to tell if this behavior actually applied, for more performance-sensitive users. PiperOrigin-RevId: 172512011
* 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

* Start process of making auto_cpu_environment_group non-experimental.Gravatar jcater2017-10-18
| | | | | | | | Adds a legacy flag so clients can continue to use both experimental_auto_cpu_environment_group and auto_cpu_environment_group until uses can be cleaned up. PiperOrigin-RevId: 172470616
* 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]).

* Fixing #3834, making sure test.log always exists.Gravatar olaola2017-10-18
| | | | | | | | Even if the test action produced no output, which it really shouldn't, Bazel should create an empty test.log file. TESTED=unit tests RELNOTES: Fixes #3834 PiperOrigin-RevId: 172412615
* Removing local fallback on failed action commands.Gravatar olaola2017-10-18

* 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. RELNOTES: None. PiperOrigin-RevId: 172367996
* 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.

* 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
* 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). Indicate that difference as such, by having a separate message for failures associated with an unconfigured label. Change-Id: I3f2e20d4dc85782eb11b104a7baf089e66d972e7 PiperOrigin-RevId: 172299938

* Add callcount system for blaze developers.Gravatar tomlu2017-10-16
| | | | | | | | | | | This simple system allows blaze developers to insert instrumentations in particular methods that they want to know: 1. How often are they called? 2. From which call sites are they called, with full call stack The output is a pprof file that can then be analysed offline. PiperOrigin-RevId: 172128440

* Expand implicitRequirements in the location of the option that required it.Gravatar ccalvarin2017-10-13
| | | | | | | | | | | Removes the special casing of implicit requirements. Accumulating them and parsing them at the end of the parse() function was never enough to actually guarantee that the value not be replaced. I've gone through all options with implicit requirements to make sure that the expectation is checked after options parsing, so this change should be relatively safe. Implicit requirements is still a broken concept - they don't actually expand based on the value given, so a user that is explicitly NOT setting a flag might unwittingly be setting all the requirements for that unset flag. Removing it fully requires redesigning or removing the flags that set it, though, so for now we are standardizing the behavior so that it behaves like any other expansion options, just one with a value. Also consolidate the deprecated wrapper option behavior into the expansion work. It will soon be removed entirely, but for now it can get grouped in with the expansion logic, so that its differences are more explicit. RELNOTES: None. PiperOrigin-RevId: 171957502

* Only delete the current execroot in clean.Gravatar Benjamin Peterson2017-10-13
| | | | | | | | | | | | | I noticed a problem where if you have a workspace with basename "server", clean will rudely delete the server's pid file and cause it to commit suicide. This is because clean deletes the deep and non-deep execroot, presumably temporarily as part of the deep execroot migration. --deep_execroot has been enabled for more than a year now, so hopefully we can safely remove this aggressive deleting. --expunge can take care of old execroots if needed.
