Hi,
I use rsync in the following way to update some remote files over a low bandwidth line:
rsync -v -r -z -t -p <local dir> <user>@<host>:<dir on host>
After updating from rsync 2.5.2 to 2.5.4 I noticed that modified files are always copied completely. The problem seems to be related to the new (in 2.5.3) option -no-whole-file. The global variable whole_file is initialized to -1 in options.c. In server_options() (options.c) it is set to zero if the original value has not been changed. A value of zero on whole_file is not transmitted to the remote rsync however.
So the remote rsync has -1 instead of zero on its whole_file variable. To fix the problem I applied the following patch that forwards --no-whole-file to the remote side if whole_file has a value of zero:
--- options.c.O Fri Mar 15 10:25:42 2002
+++ options.c Fri Mar 15 10:27:24 2002
