I am considering a patch that would exclude compressing a given list of file extensions when the -z option is used. Users may want to use -z, but not want to try to compress .gz, .jpg, .mp3, etc. type files. Rsyncd has this feature with it's "dont compress" option, but I think many users are using rsync over ssh and therefore do not have this functionality available to them.
The way my test code works is by modifying the set_compression() function in token.c and using the wildmatch() function, exactly like rsyncd's dont compress option is doing now. If this seems useful, I want to receive input on how to implement the user-interface. I was thinking about two command line options, --dont-compress and --dont-compress-from. This is what it would look like: rsync -z --dont-compress="*.mp3 *.gz ....." However, since this list could be very long, you would also have: rsync -z --dont-compress-from=/etc/rsync/already_compressed.txt where the already_compressed.txt would have a list of extensions not to compress. Another option, is to have --dont-compress and --dont-compress-from use rsync's Exclude Patterns, but I have not studied this code and do not know how much harder this would be to implement. Any thought? -John -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
