+Subject: [PATCH] afsql: afsql_dd_insert_db() refactor
+
+Upstream-Status: Backport
+
+A lot of the code that was previously in afsql_dd_insert_db() have been
+extracted to smaller functions, and afsql_dd_insert_db() was rebuilt on
+top of these. At the same time, memory leaks were plugged, and in case
+of a transaction error, backlog rewinding has been fixed too, to not
+loose messages since the last BEGIN command.

+Subject: [PATCH] mainloop: Deinit the new config when reverting to the old one
+
+Upstream-Status: Backport
+
+When reloading, and the new config fails, deinit it before initializing
+the old config. This is so that conflicting things do not remain held by
+the half-initialized new config, while the old tries to take it
+over. (It also removed a couple of memory leaks, most likely.)
+
+The reason we can do this, is because cfg_tree_stop() (called by
+cfg_deinit()) goes over all the known nodes, and log_pipe_deinit() is
+also smart enough to not deinit a node that has not been inited before.

+SUMMARY = "Alternative system logger daemon"
+DESCRIPTION = "syslog-ng, as the name shows, is a syslogd replacement, \
+but with new functionality for the new generation. The original syslogd \
+allows messages only to be sorted based on priority/facility pairs; \
+syslog-ng adds the possibility to filter based on message contents using \
+regular expressions. The new configuration scheme is intuitive and powerful. \
+Forwarding logs over TCP and remembering all forwarding hops makes it \
+ideal for firewalled environments. \
