Example 11 with FileSystem

use of com.google.devtools.build.lib.vfs.FileSystem in project bazel by bazelbuild.

the class DarwinSandboxedStrategy method getWritableDirs.

Example 12 with FileSystem

use of com.google.devtools.build.lib.vfs.FileSystem in project bazel by bazelbuild.

the class FsApparatus method newNative.

/**
   * When using a Native file system, absolute paths will be treated as absolute paths on the unix
   * file system, as opposed to paths relative to the backing temp directory. So for simplicity,
   * you ought to only use relative paths for FsApparatus#file, FsApparatus#dir, and
   * FsApparatus#path. Otherwise, be aware of the following issue
   *
   *   Path p1 = scratch.path(...);
   *   Path p2 = scratch.path(p1.getPathString());
   *
   * We'd like the invariant that p1.equals(p2) regardless if scratch is in-memory or not, but this
   * does not hold with our usage of Unix filesystems.
