1790960 - FS: Start using XPCOM streams for file reads and writes

Status: RESOLVED FIXED

(Core :: DOM: File, task, P2)

Description

[Jan Varga [:janv]]

Currently, we use direct low level calls like PR_Read and PR_Write which limit our ability to do quota checks using existing stream wrappers.

The transition to streams will also allow:

• add any other stream wrapper, for example encryption/decryption for private browsing
• do I/O on a background thread pool
• cancel the reading or writing (for example during app shutdown or window/worker teardown or when a clear origin operation has been requested)
• to respond to control runnables in workers
