afdf5483c9
full diff: 26c1120b8d...efbc4488d8
Relevant changes:
- sysx/xattr: fix and improve
- fix getxattrAll: change initial buffer size to 128 to prevent unneeded
iterations and change the logic to get the real size in case we get ERANGE
rather than doubling the buffer)
- improve listxattrAll; refactor for readability, prevent calling `listxattr()`
twice. Handle condition when attributes size is changed in between the two
calls to listxattr().
- Remove Windows' Readlink fork
- Drops support for Go 1.12 and under
- Fix sameFile() to recognize empty files as the same
- fixes "Empty files can diff as "modified" even when they're not"
