* c++,runfiles: move runfiles libraryGravatar Laszlo Csomor2018-04-30
| | | | | | | | | | | | | | | | Move the half-done C++ runfiles library to `//tools/cpp/runfiles`. (The Python and Bash runfiles libraries are already under `//tools/<language>/runfiles`.) See https://github.com/bazelbuild/bazel/issues/4460 Change-Id: I1006f7f81462ea0e4b1de1adcdba89e386d4f9e7 Closes #5107.

* windows,client: no longer support Unix-style pathsGravatar Laszlo Csomor2018-04-26
| | | | | | | | | | | | | | The Bazel client no longer supports MSYS paths. The only exception is "/dev/null" which the client treats as "NUL". After this change you can no longer pass MSYS paths as Bazel flag values on Windows. See https://github.com/bazelbuild/bazel/issues/4319 Change-Id: I39d81843015c5a4014dd5953bac2e1c29dcd5bed PiperOrigin-RevId: 194372504
* windows,client: fix error reportingGravatar Laszlo Csomor2018-04-24
| | | | | | | | | | | | | | | | | | | | | | Fix error reporting in the path conversion methods of the Bazel client. Previously the error reporting logic used GetLastErrorString in places where it was not appropriate (i.e. it was not a failed Windows API call that caused an error). This cleanup prepares removing the concept of the MSYS root from the Bazel client, since MSYS paths are no longer supported and we want to cut Bazel's dependency on Bash (thus MSYS) completely. See https://github.com/bazelbuild/bazel/issues/4319 Change-Id: Ie50a20e0ee0c572592f637340a2f2948c7f53088 Closes #5072.

* Declare internal helper functions in option_processor-internal.Gravatar ccalvarin2018-04-23
| | | | | | | It's better for testing, while keeping it clear that these functions should not be used outside of option_processor.cc. RELNOTES: None. PiperOrigin-RevId: 193947022
* Remove overlap between the blazerc and bazelrc names.Gravatar ccalvarin2018-04-20
| | | | | | | | Bazel now has its own subclass of StartupOptions to specify bazel-only options. This is needed for https://github.com/bazelbuild/bazel/issues/4502. RELNOTES(INC): No longer accepts --blazerc or --[no]master_blazerc, accepts bazelrc name only. PiperOrigin-RevId: 193718297
* Reduce the state kept in OptionProcessor.Gravatar jmmv2018-04-19
| | | | | | | | | | | | | | | Make the list of rc files a local variable as it need not be a class attribute, and drop the unused rcoptions_ field. This is a trivial refactoring and the remaining code is still too confusing. It'd be worth splitting OptionProcessor in two pieces: OptionProcessor to exclusively keep the virtual ParseOptions method and no state, and a new ParsedOptions type to act as the immutable return value of ParseOptions. This would decouple all state mutations. RELNOTES: None. PiperOrigin-RevId: 193557347
* Refactor where rc files are controlled.Gravatar ccalvarin2018-04-19
| | | | | | | In preparation for https://github.com/bazelbuild/bazel/issues/4502, make OptionProcessor::GetRcFiles contain the logic for both the user bazelrcs and the master bazelrcs. RELNOTES: None PiperOrigin-RevId: 193521683
* windows: change output_base name computationGravatar Laszlo Csomor2018-04-19
| | | | | | | | | | | | | | | | | Change GetHashedBaseDir in the Bazel client on Windows, to only use an alphabet of 32 characters, not of 64. The 64-element alphabet contained effective repetitions because path names on Windows are case-insensitive.

* Made 'file_posix.cc' POSIX compatibleGravatar Jasper Siepkes2018-04-09
| | | | | | | | | | | | | | | | The `d_type` field is not part of the POSIX specification. Added a compile time check to see if we can use it. When not present fallback to a (slightly more expensive) call to 'stat'. The reason why I need this is because I'm trying to port Bazel to a POSIX compliant platform. Even though my porting effort might fail miserably ;-) I think having a POSIX implementation which is POSIX compliant would be of benefit to the Bazel project. Besides the POSIX spec I've based the implementation on information I found here: * https://stackoverflow.com/questions/2197918/cross-platform-way-of-testing-whether-a-file-is-a-directory * https://stackoverflow.com/questions/23958040/checking-if-a-dir-entry-returned-by-readdir-is-a-directory-link-or-file#answer-29094555 * https://stackoverflow.com/questions/39429803/how-to-list-first-level-directories-only-in-c/39430337#39430337 Closes #4967.

* Remove die() and replace it with BAZEL_DIE, part of the logging framework.Gravatar ccalvarin2018-04-06

* Create BAZEL_DIE macro.Gravatar ccalvarin2018-04-03

* Make the client's java startup command line list all startup options.Gravatar ccalvarin2018-03-30
| | | | | | | | | | | We expect that the client passes all startup options to the server, default or explicit. The server's listing of default values should not matter. Yet for a number of these options, the default value in the server was relied upon, because the server command line was not constructed with the client's default value included. Fix visible cases of this, long term this should be tested for, so the invariant is not broken again. This has been the documented expectation for a long time, but a number of violations have crept up over time. Update the comments that lead to this expectation to be more realistic. Add debug statement that shows which options are changed when startup options cause the server to be restarted. The detailed logs will only be seen if --client_debug is set to TRUE. RELNOTES: None. PiperOrigin-RevId: 191066983
* Remove pdie.Gravatar ccalvarin2018-03-29
| | | | | | | pdie and die are pretty similar, pdie just adds the errno string or equivalent from GetLastErrorString(). Make this explicit. This makes message formatting more clear in preparation for moving these all to BAZEL_LOG. RELNOTES: None. PiperOrigin-RevId: 190957255
* Remove startup JVM version checkGravatar cushon2018-03-29
| | | | | | | | | | | | This was added during the JDK 7->8 transition to improve the diagnostic when an older-than-supported host_javabase was used. The version number handling doesn't work with JDK 9 (see [1]), and using Bazel binaries with a bundled host_javabase avoid the error entirely so the message is less important.

* Remove the --allow_configurable_attributes startup option.Gravatar ccalvarin2018-03-27
| | | | | | | It was removed from the java code 4 years ago, mentioning it causes the server to crash at startup. RELNOTES: None. PiperOrigin-RevId: 190636455
* Fold in warning and error output into client logging.Gravatar ccalvarin2018-03-23
| | | | | | | To replace blaze_util::die and blaze_util::pdie as well, FATAL statements need to accept blaze exit codes. RELNOTES: None. PiperOrigin-RevId: 190285798
* Update the client's skeleton logging framework to use it for --client_debug.Gravatar ccalvarin2018-03-21
| | | | | | | | | We are still unable to turn this on to write to files, but there are currently 2 logging systems in use in the client: the inactive one, and the print-to-stderr option triggered by --client_debug. Combine these, so we can use the same logging format for both. Also combine it with the VerboseLogging functionality - it was not documented anywhere and seems redundant. RELNOTES: None.

* Convert static std::set to constexpr arrayGravatar Loo Rong Jie2018-03-01
| | | | | | | | | | | | | Google C++ Style Guide disallows static variable with non-trivial destructor. Use constexpr for static variable whenever possible. std::array would make the code cleaner, but MSVC's implementation of constexpr std::array is buggy. Side-benefit: linear search is faster when array is small (<20). Change-Id: Ic8244dcb868e27d02ceb5298ccec482e7d4254b7 PiperOrigin-RevId: 187451495

| | | | | | | | | | | | | | | | In MSVC, `environ` is a macro (from `stdlib.h`): ```cpp extern char*** __p__environ(void); #define _environ (*__p__environ()) #define environ _environ ``` So `extern char **environ;` will be expanded as `extern char **(*__p_environ());` which is invalid.

| | | | | | | | | Fail fast if we are about extract the Bazel binary for version V into the predetermined install_base directory for version V'. This fixes Bazel's weakness to a race condition that puts it in a stable inconsistent state where all current and future attempts to use Bazel at version V will actually use V'. A rerun of the Bazel client will be able to successfully use version V'. This race condition occurs when the Bazel binary is replaced after determine the install directory (via the install_base_key file in the Bazel zip) but before we extract the files in the zip into the directory.
