+DAEMON --------------------------------------------------------------
+
+server-imposed bandwidth limits
+rsyncd over ssh
-IMPORTANT ------------------------------------------------------------
+ There are already some patches to do this.
-Cross-test versions
+ BitKeeper uses a server whose login shell is set to bkd. That's
+ probably a reasonable approach.
- Part of the regression suite should be making sure that we don't
- break backwards compatibility: old clients vs new servers and so
- on. Ideally we would test the cross product of versions.
- It might be sufficient to test downloads from well-known public
- rsync servers running different versions of rsync. This will give
- some testing and also be the most common case for having different
- versions and not being able to upgrade.
+FEATURES ------------------------------------------------------------
+
+
+--dry-run is insufficiently dry
+
+ Mark Santcroos points out that -n fails to list files which have
+ only metadata changes, though it probably should.
+
+ There may be a Debian bug about this as well.
+
use chroot

http://lists.samba.org/pipermail/rsync/2001-September/thread.html
+
--files-from
Avoids traversal. Better option than a pile of --include statements
for people who want to generate the file list using a find(1)
command or a script.
+
File list structure in memory
Rather than one big array, perhaps have a tree in memory mirroring
which should just take a small change to the parser code.
+
Errors
If we hang or get SIGINT, then explain where we were up to. Perhaps
eof" give a message that is more detailed if possible and also more
helpful.
+ If we get an error writing to a socket, then we should perhaps
+ continue trying to read to see if an error message comes across
+ explaining why the socket is closed. I'm not sure if this would
+ work, but it would certainly make our messages more helpful.
+
+ What happens if a directory is missing -x attributes. Do we lose
+ our load? (Debian #28416) Probably fixed now, but a test case
+ would be good.
+
+
File attributes
Device major/minor numbers should be at least 32 bits each. See
versions.
-logging
-
- Perhaps flush stdout after each filename, so that people trying to
- monitor progress in a log file can do so more easily. See
- http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=48108
-
- At the connections that just get a list of modules are not logged,
- but they should be.
-
-rsyncd over ssh
-
- There are already some patches to do this.
-
proxy authentication
Allow RSYNC_PROXY to be http://user:pass@proxy.foo:3128/, and do
structures.

+
+ I think that would be good too. For example, people uploading files
+ to a web server might like to say
+
+ rsync -avzP --chmod a+rX ./ sourcefrog.net:/home/www/sourcefrog/
+
+ Ideally the patch would implement as many of the gnu chmod semantics
+ as possible. I think the mode parser should be a separate function
+ that passes back something like (mask,set) description to the rest of
+ the program. For bonus points there would be a test case for the
+ parser.
+
+ (Debian #23628)
+
+
+--diff
+
+ Allow people to specify the diff command. (Might want to use wdiff,
+ gnudiff, etc.)
+
+ Just diff the temporary file with the destination file, and delete
+ the tmp file rather than moving it into place.
+
+ Interaction with --partial.
+
+ Security interactions with daemon mode?
+
+ (Suggestion from david.e.sewell)
+
+
+Incorrect timestamps (Debian #100295)
+
+ A bit hard to believe, but apparently it happens.
+
+
+Check "refuse options works"
+
+ We need a test case for this...
+
+ Was this broken when we changed to popt?
+
+
+String area code
+
+ Test whether this is actually faster than just using malloc(). If
+ it's not (anymore), throw it out.

-hang/timeout friendliness

+ Use a separate function for reporting errors; prefix it with

verbose output

correctly.
