rsync - Dec 2007 - Problem with filenames with commas in them

This is a continuation of my previous problem where cp could copy
files whereas rsync couldn't.  It turns out that the problem is with
files which have commas in their names, rsync can write the initial
version of the file but it can't check/rewrite them.

Here is the error I get from rsync when trying to overwrite the files
(using --inplace) :-

    home# rsync -r --inplace .in /freecom/backup/home/chris/Mtest/   
    rsync: open
"/freecom/backup/home/chris/Mtest/.in/audacity/cur/1172007150.76430_0.newred:2,"

    rsync: open

    rsync: open

    rsync: open

    rsync: open
"/freecom/backup/home/chris/Mtest/.in/freecycle/cur/1172005922.70482_0.newred:2,S"
failed: Input/output error (5)
    rsync error: some files could not be transferred (code 23) at main.c(977)
[sender=2.6.9]

Now if I do a find for the maildir files in the destination directory
I see:-

    ./audacity/cur/1172007150.76430_0.newred:2,
    ./audacity/cur/1172012773.6188_0.newred:2,

    ./audacity/cur/1172038263.69147_0.newred:2,
    ./cafe/new/1172050891.76512_0.newred

    ./ixion/new/1172051518.79746_0.newred
    [snip lots more]

The five errors are on the only five files that have commas in their
names.  Now this *may* be because the destination can't cope with
filenames with commas in very well but the files are certainly
accessible on the destination and appear quite normal.

An "rsync -r" without the --inplace just gets a different error:-

    rsync: rename
"/freecom/backup/home/chris/Mtest/.in/audacity/cur/.1172007150.76430_0.newred:2,.V9Pd4n"
-> ".in/audacity/cur/1172007150.76430_0.newred:2,": Input/output
error (5)



.... and *anyway* why is rsync trying to copy these files at all,
they're unchanged!

... I have found a solution, I had to install rsync version 3.0.0 to
get it though.

If I use the --temp-dir option to put temporary files on the local
ext3 filesystem then the rsync succeeds, hurrah!  :-)

    home# /usr/local/bin/rsync -r --temp-dir=/tmp .in
/freecom/backup/home/chris/Mtest
    home#
    
(I have the version 3.0.0pre6 installed in /usr/local/bin at the
moment)

While I'm about it the alternative -T option for --temp-dir doesn't
work, rsync just says "-T=/tmp: unknown option".

Still I seem to have a fix for my problem.
