* Replace all usages of Blaze's Preconditions class with guava.Gravatar tomlu2017-11-09
| | | | | | | | Blaze had its own class to avoid GC from varargs array creation for the precondition happy path. Guava now (mostly) implements these, making it unnecessary to maintain our own. This change was almost entirely automated by search-and-replace. A few BUILD files needed fixing up since I removed an export of preconditions from lib:util, which was all done by add_deps. There was one incorrect usage of Preconditions that was caught by error prone (which checks Guava's version of Preconditions) that I had to change manually. PiperOrigin-RevId: 175033526
* Make --watchfs a common command option.Gravatar Ulf Adams2016-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | Adding an options parameter to DiffAwareness#getCurrentView seems like the simplest way to achieve that. Alternatives considered: 1. Making the diff awareness modules stateful. However, I did not want to do so as I've also been working on improving the module API to reduce state, or at least to have a proper lifecycle management for any necessary state. 2. Making the watchFs flag a constructor parameter. However, that would also invalidate any implementations that don't use the flag (of which we have several). 3. Only passing in a single boolean flag instead of an options class provider; however, this is a more principled, futureproof API, which allows other modules / awareness implementations to use their own options. RELNOTES: --watchfs is now a command option; the startup option of the same name is deprecated. I.e., use bazel build --watchfs, not blaze --watchfs build. -- MOS_MIGRATED_REVID=136154395

* Introduce FsEventsDiffAwareness for OS X.Gravatar Damien Martin-Guillerez2016-06-02
Use FsEvents API (https://developer.apple.com/library/mac/documentation/Darwin/Reference/FSEvents_Ref) to watch the file system. This change also refactor the LocalDiffAwareness to extract the WatchService specific part. It now select the FsEventsDiffAwareness on OSX and the WatchServiceDiffAwareness on Linux. RELNOTES[NEW]: On OSX, --watchfs now uses FsEvents to be notified of changes from the filesystem (previously, this flag had no effect on OS X). Fixes #1074. -- Change-Id: I927951468e4543a399e0e0ad0f1dd23d38ce15a0 Reviewed-on: https://bazel-review.googlesource.com/3420 MOS_MIGRATED_REVID=123854017
