#22590: rsync can silently corrupt OS X files due to lack of extended attribute
support
-------------------------+--------------------------------------------------
Reporter: nad@… | Owner: macports-tickets@…
Type: defect | Status: new
Priority: Normal | Milestone:
Component: ports | Version: 1.8.1
Keywords: | Port: rsync
-------------------------+--------------------------------------------------
The MacPorts rsync lacks the Apple-specific modifications to support
extended attribute and resource fork copy.
-E, --extended-attributes copy extended attributes, resource
forks
vs
-E, --executability preserve executability
This is particularly nasty because at least one popular port (git-core)
pulls in rsync as a dependency and -aE is a valid option in both versions
of rsync. So, when users install git-core via MacPorts, they may not
realize that rsync is also being installed and, if they use rsync to
backup OS X files, they may not find out until it is too late that crucial
HFS metadata (like resource forks and other extended attributes) were not
copied as expected if the Apple rsync had been used.
I would think the best solution would be to forward port the Apple -E
changes but, if that's not possible, there should be some other change,
perhaps a warning when -E is selected. Or remove the dependency in git-
core on rsync. As it stands, considering the popularity of rsync as a
backup solution, it is way too easy for users to end up with silently
corrupted files.
