Description Stef walter 2008-03-11 12:24:50 UTC
Seems like rsync 3.0.0 daemon process will assert when using --append under certain circumstances. 

 * This worked in 2.9.6. 
 * Removing the --append option avoids the assertion.
 * Tried to make a test case using less rsync options, but the 
   problem becomes harder for me to reproduce.

Whoops, my command line was actually:


/usr/local/bin/rsync -aREHx --inplace --append --links --ignore-errors --delete
--delete-excluded --delete-during --exclude-from - --stats --progress
/data/d2/comictrax.net/./ m3i::d1/comictrax.net

The latest dev source should have this fixed (e.g. git repository, latest "nightly" tar file).  There were quite a few issues with skipped hard-linked files (via --append, --ignore-existing, etc.) that could cause problems (I saw both the assert error you cited and a hang).  I also noticed that older versions of rsync were not doing the right thing in some of the option cases (e.g. hard-linking files into place that did not exist, even though --ignore-non-existing was specified).  So, this should both fix the regression and improve several things.

Thanks for the report!

Also, as a bonus, I noticed this log entry was bogus, and fixed that too:
