Add support for logging daemon messages to an SQL database.
-After applying this patch you'll need to run autoconf and autoheader to
-generate updated versions of "configure" and "config.h.in".
+After applying this patch, run these commands for a successful build:
-You'll need to run configure with the --with-ODBC option in order for the
-extended features to be active.
+ autoconf
+ autoheader
+ ./configure --with-ODBC
+ make proto
+ make
-Patch provided by Steve Sether.
+Steve Sether writes:
-(Tweaked by Wayne Davison for rsync-style purposes but not compiled, so if the
-dblog.c file has a compile problem, it's probably my fault...)
+This patch adds the following options:
+"database logging"
+ If set to True, rsync will attempt to connect to
+ the specified datasource and write to the named tables.
+ Defaults to False.
