The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

|
|
* RemoteOpenFileChild: a thin wrapper around regular nsIFile classes that does
|
|
* IPC to open a file handle on parent instead of child. Used when we can't
|
|
* open file handle on child (don't have permission), but we don't want the
|
|
* overhead of shipping all I/O traffic across IPDL. Example: JAR files.
|
|
*
|
|
* To open a file handle with this class, AsyncRemoteFileOpen() must be called
|
|
* first. After the listener's OnRemoteFileOpenComplete() is called, if the
|
|
* result is NS_OK, nsIFile.OpenNSPRFileDesc() may be called to get a
|
|
* duplicated file descriptor.
|
|
*
|
|
* Note that the file descriptor returned by NSPRFileDesc() is duplicated from
|
|
* the original, which shares its file offset with the original. If the file
|
|
* offset is modified (ex: by lseek/read/write) on one of the shared
|
|
* descriptors, the offset is also changed for the other. It can be safely
|
|
* used only with operations that take absolute offsets, such as
|
|
* mmap/pread/pwrite.
|
|
*
|
|
* This class should only be instantiated in a child process.
