VM Maker: FileAttributesPlugin.oscog-AlistairGrant.39.mcz

commits-2
 
Eliot Miranda uploaded a new version of FileAttributesPlugin to project VM Maker:
http://source.squeak.org/VMMaker/FileAttributesPlugin.oscog-AlistairGrant.39.mcz

==================== Summary ====================

Name: FileAttributesPlugin.oscog-AlistairGrant.39
Author: AlistairGrant
Time: 4 October 2018, 8:34:34.356792 am
UUID: 986e319e-eadc-4852-853e-715149efa50e
Ancestors: FileAttributesPlugin.oscog-AlistairGrant.38

FileAttributesPlugin v2.0.1

1. The following primitives weren't updated as part of the support file restructure:

- primitiveChangeMode
- primitiveChangeOwner
- primitiveSymlinkChangeOwner
- primitiveRewinddir

Get these working again in the new framework (fapath).

2, Rewinding the directory on Windows returns the first entry.
Modify the primitive to behave this way on all platforms.

3. Path conversion primitives shouldn't include the Long Path Prefix on
Windows as part of the path.
