Description Andrew Liles 2004-07-07 14:46:07 UTC
I use rsync on Cygwin and have found a new bug in version 2.6.2 that seems to 
be related to the combination of command line options.

I have 2 test cases and 2 machines.  Test case 1 succeeds on machine A & B
test case 2 fails on machine A (newer rsync) and succeeds on B.

Test Case 1 (both machines ok):
rsync -v --password-file .rsync.secrets t.txt 
backupjudi2@host.starfishzone.com::judi2/

Test Case 2 (fails on machine B):
rsync -v --modify-window=1 --password-file .rsync.secrets t.txt 
backupjudi2@host.starfishzone.com::judi2/

Machine A (failing on test 2):
Windows XP Home
CYGWIN_NT-5.1 judi 1.5.10(0.116/4/2) 2004-05-25 22:07 i686 unknown unknown 
Cygwin
rsync  version 2.6.2  protocol version 28

Machine B (both test ok)
Windows XP Home
CYGWIN_NT-5.1 Dell3 1.5.5(0.94/3/2) 2003-09-20 16:31 i686 unknown unknown 
Cygwin
rsync  version 2.5.7  protocol version 26

Error says:
@ERROR: auth failed on module judi2
rsync: connection unexpectedly closed (102 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) 
at /home/lapo/packaging/tmp/rsync-2.6.2/io.c(342)

I have tried to use the
	--rsync-path=/SOME/PATH/rsync-debug 
but this does not go into debug mode nor create a trace file under Cygwin; it 
seems to ignore the option.

Please let me know if this is something I should submit to the Cygwin folk.

WORKAROUND: 
don't use the modify-window option(!)
Comment 1 Wayne Davison 2005-02-25 11:14:55 UTC
I am unable to duplicate this using 2.6.3 on cygwin.  Do you still see this
problem?  The only theory I have is that the asprintf() call that is used to
create the --modify-window option that is passed to the server was not working
right in that build of rsync (or perhaps in that version of cygwin's library?).

If you still see the problem, try specifying --max-delete=200 instead of
--modify-window=1 and see if there is a problem for that option as well.  If so,
it is likely to be an asprintf()-related bug.

I haven't been able to duplicate this bug.
