SVN rev 214697 on 2010-11-02 22:49:20Z by pjd
MFC r214119,r214273,r214274,r214275,r214276,r214282,r214283,r214284,r214692:
r214119:
Use closefrom(2) instead of close(2) in a loop.
r214273:
Load geom_gate.ko module after parsing arguments.
r214274:
Plug memory leaks.
Found with: valgrind
r214275:
Plug memory leak.
r214276:
Simplify code a bit.
r214282:
Move all NV defines into nv.c, they are not used externally thus there is
no need to make then visible from outside.
r214283:
Implement nv_exists() function that returns true if argument of the given
name exists.
r214284:
Before this change on first connect between primary and secondary we
initialize all the data. This is huge waste of time and resources if
there were no writes yet, as there is no real data to synchronize.
Optimize this by sending "virgin" argument to secondary, which gives it a hint
that synchronization is not needed.
In the common case (where noth nodes are configured at the same time) instead
of synchronizing everything, we don't synchronize at all.
r214692:
Send packets to remote node only via the send thread to avoid possible
races - in this case a keepalive packet was send from wrong thread which
lead to connection dropping, because of corrupted packet.
Fix it by sending keepalive packets directly from the send thread.
As a bonus we now send keepalive packets only when connection is idle.
