2008-04-07Added method Path::getDirname().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49352 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-03Re-implemented Path::createDirectoryOnDisk (for Unix).Ted Kremenek
This method allows one to create a directory, and optionally create all parent directories that do not exist. The original implementation would require that *all* directories along a path are writable by the user, including directories that already exist. For example, suppose we wanted to create the directory "/tmp/foo/bar", and the directory "/tmp" already exists, but not "/tmp/foo". Since "/tmp" is writable by all users, the original implementation would work, and create "/tmp/foo", followed by "/tmp/bar". A problem occurred, however if one wanted to created the directory "/Users/myuser/bar" (or equivalently "/home/myuser/bar"), and "/Users/myuser" already existed and is writable by the current user. The directory "/User/myuser" is writable by the user, but "/User" is not. The original implementation of createDirectoryOnDisk would return with failure since "/User" is not writable, even though "/User/mysuser" is writable. The new implementation works by recursively creating parents as needed, and thus doesn't need to check the permissions on every directory in a path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49162 91177308-0d34-0410-b5e6-96231b3b80d8
