Re: [rdiff-backup-users] Invalid mode: rb?

[Andrew Ferguson]

Hi Kevin,

I believe I have resolved your issue.

The error number (102) returned by the C test program I sent you is an
error specific to sockets. However, when you did `ls -al` and got

-rwxr-xr-x 1 kwh staff   0 Apr  3 18:38 Commands*
-rwxr-xr-x 1 kwh staff   0 Apr  3 18:38 Notification*

ls did not indicate that those files are sockets! I installed Adobe
Reader 8 on my PPC Mac and got it to create those files, so I did:

$ ls -l ~/Library/Acrobat\ User\ Data/8.0_ppc/Synchronizer/
srwxr-xr-x    1 owsla  owsla    0B Jul 16 13:04 Commands
srwxr-xr-x    1 owsla  owsla    0B Jul 16 13:04 Notification

See the difference in the first character?

I backed-up the directory with rdiff-backup and uncovered a bug related
to extended attributes, which I have fixed in CVS for version 1.1.13.
However, I was not able to trigger the bug you got because my system is
correctly interpreting those files as sockets.

Something is broken for you below the level of rdiff-backup, and below
the level of python. What happens if you run:

$ file ~/Library/Acrobat\ User\ Data/8.0_ppc/Synchronizer/

I get 'socket' listed for both of those files.

I suggest three possible remedies:

1) Run 'Repair Disk Permissions' using Apple's Disk Utility
2) Delete the Synchronizer folder. Acrobat will recreate it if needed
3) Reinstall Adobe Reader 8


Since rdiff-backup isn't being told that those files are sockets, it
proceeds with trying to open them with 'rb' as the mode, triggering the
ListError that you observe.

Best,
Andrew
