+This adds the --ignore-case option, which makes rsync compare filenames
+in a case-insensitive manner.
-Peter Tattam [peter@jazz-1.trumpet.com.au] writes:
+To use this patch, run these commands for a successful build:
-> I believe a suitable workaround would be to ignore case for file names
-> when the rsync process is undertaken. Is this facility available or
-> planned in the near future?
+ patch -p1 <patches/ignore-case.diff
+ ./configure (optional if already run)
+ make
-I've attached a context diff for some changes I made to our local copy
-a while back to add an "--ignore-case" option just for this purpose.
-In our case it came up in the context of disting between NTFS and FAT
-remote systems. I think we ended up not needing it, but it does make
-rsync match filenames in a case insensitive manner, so it might at
-least be worth trying to see if it resolves your issue.
+TODO:
-A few caveats - both ends have to support the option - I couldn't make
-it backwards compatible because both ends exchange information about a
-sorted file list that has to sort the same way on either side (which
-very subtly bit me when I first did this). I also didn't bump the
-protocol in this patch (wasn't quite sure it was appropriate just for an
-incompatible command line option) since it was for local use.
+ - Make this code handle multibyte character encodings, and honor the
+ --iconv setting when converting case.
-NOTE: patch updated for latest CVS source by Wayne Davison, but UNTESTED!
