Reworking File

[james-pre]

Currently, File is a wrapper for a path, position, and any changed data. I think it would make sense to consolidate the internal functionality on FileSystem, then to provide a mechanism for syncing. I'm currently thinking of these changes:

1. Change FileSystem#sync to only handle synchronizing, not updating data (breaking)
   • This would also need some tweaking of the Readonly mixin.
2. Add a new method to FileSystem for updating metadata/stats
3. Move File into the VFS (breaking)
4. Remove the openFile method of FileSystem (breaking)
5. Rework the createFile method of FileSystem to not return a File— maybe Stats instead (breaking)

For the most part, this would make things much easier to maintain.

The non-breaking changes that can be done before 2.0:

• The new FileSystem method (2)
• The functionality for sync-only sync (1)
• Deprecate old code paths
• Rewrite the relevant parts of the VFS to use the new code paths

Other than that, a breaking 2.0 release is needed.

I'm creating this discussion to get community feedback on this, please let me know if you have any questions or concerns!
