* Remove synchronization from file system.Gravatar tomlu2017-12-28
| | | | | | | | | | After the path refactor we will no longer have path instances to synchronize on. The underlying OS file systems are already naturally thread safe, that is, their internal data structures cannot be damaged. Any further synchronization (eg. races between directory creation and deletion) has to be managed at the client level. The last attempt to do this failed because of races in FileUtils#createDirectoryAndParents on Windows. This method is now gone, replaced by a method from the Java framework that knows how to synchronize. PiperOrigin-RevId: 180290901
* Add FileSystem#createDirectoryAndParents.Gravatar tomlu2017-12-21
| | | | | | | | A native implementation of this (instead of using FileSystemUtils, which can only use public interfaces) should be more efficient and more easy to make correct. In particular, it should allow removing FileSystemUtils#createDirectoriesAndParents, which has poor thread safety characteristics. The latter method has a lot of logic that forces certain unnatural atomicity guarantees on createDirectory, and it also has logic that is conditional on sub-string content of exception messages.

* Refactor the FileSystem API to allow for different hash functions.Gravatar buchgr2017-11-30
| | | | | | | | | | | | | Refactor the FileSystem class to include the hash function as an instance field. This allows us to have a different hash function per FileSystem and removes technical debt, as currently that's somewhat accomplished by a horrible hack that has a static method to set the hash function for all FileSystem instances. The FileSystem's default hash function remains MD5. RELNOTES: None PiperOrigin-RevId: 177479772
* 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
* Change FileSystem#getDirectoryEntries to return strings of the ↵Gravatar tomlu2017-10-23

* Add Path argument to supportsModifications, supports*LinksNatively.Gravatar tomlu2017-10-20
| | | | | | | | This works better with UnionFileSystem, as (eg.) different mapped file systems might not agree on whether they are read-only. No actual code changes have been made that actually uses this argument, so this should be a behaviour no-op. PiperOrigin-RevId: 172782759

* Rather than logging the amount of free physical memory on Linux systems, log ↵Gravatar Googler2017-10-06
| | | | | | the amount of *available* physical memory. This includes memory used as cache or buffer that will be evicted if an application requests memory, and is a much more realistic metric of utilization than free memory, which is usually <1% of memory available to the machine.

Adding an option to set the hash function in the remote worker, defaulting to the current behavior (unfortunately it is a build option, have not found a clean way to specify it at runtime).

* Refactor all ctor callsites of PathFragment to instead call a static ↵Gravatar nharmata2017-04-05
| | | | | | | | | | | | 'create' method. This paves the way for changing PathFragment to e.g. an abstract class with multiple subclasses. This way we can split out the windows-specific stuff into one of these concrete classes, making the code more readable and also saving memory (since the shallow heap size of the NonWindowsPathFragment subclass will hopefully be smaller than that of the current PathFragment). This also lets us pursue gc churn optimizations. We can now do interning in PathFragment#create and can also get rid of unnecessary intermediate PathFragment allocations.

* Move UnixFileSystem to lib.unix, WindowsFileSystem to lib.windowsGravatar Ulf Adams2017-02-28

* Move FileAccessException to the vfs packageGravatar Ulf Adams2017-02-17
| | | | | | | | | | | | | | It was previously in unix, but also used from non-unix file systems, which means it's not actually unix-specific. This is in preparation for splitting compilation of the unix and windows file systems into separate libraries. That improves layering and reduces compile times - note that Bazel already injects the vfs into its lower layers, which should only rely on the normal vfs APIs, not on anything platform-specific. -- PiperOrigin-RevId: 147829659 MOS_MIGRATED_REVID=147829659
