| | | | | | | | | | | | | | | | | | iff we have a connection open to the main daemon there are some child processes where we do not create a connection to the main daemon (switch_from_server_to_client()) because it is expensive to set up and we normally might not need to talk to the daemon at all via a domainsocket. but we might want to still call to ctdb_ltdb_store() from such chil processes.

* rb_tree: fix possible access-after-free-error in trbt_traversearray32_nodeMichael Adam2011-12-231-4/+7
| | | | | | | | | When the traverse callback frees the current node, the traverse of the rbtree can fail (the next node->right fails since node is not there any more...). This is fixed by introducing variables to store the right (and left) pointers before the callback is called. (This used to be ctdb commit 8b0caaeed154d26c67a73659d3bbbdd63b21be11)

| |/ | | | | | | | | | | | | | | | | | | | | Following connection to the local ctdbd, ctdb_cmdline_client() currently issues a CTDB_CONTROL_GET_PNN request with a fixed 3 second timeout. The ctdb cmd line client accepts a --timelimit argument for specifying a per request timeout, pass this value through to ctdb_cmdline_client() for use as a CTDB_CONTROL_GET_PNN request timeout.

* io: Make queue_io_read() safe for reentryDavid Disseldorp2011-08-051-74/+63
| | | | | | | | | | | | | | | | | | queue_io_read() may be reentered via the queue callback, recoverd is particularly guilty of this. queue_io_read() is not safe for reentry if more than one packet is received and partial chunks follow - data read off the pipe on re-entry is assumed to be the start-of-packet four byte length. This leads to a wrongly aligned stream and the notorious "Invalid packet of length 0" errors. This change fixes queue_io_read() to be safe under reentry, only a single packet is processed per call. https://bugzilla.samba.org/show_bug.cgi?id=8319 (This used to be ctdb commit 9ea41d2fab612772f861270c8a59c01c43bd3a4c)

* Remove LACOUNT and LACCESSOR and migrate the records immediately.Ronnie Sahlberg2011-02-181-1/+0
| | | | | | | | | | | | | | | This concept didnt work out and it is really just as expensive as a full migration anyway, without the benefit of caching the data for subsequence accesses. Now, migrate the records immediately on first access. This will be combined with a "cheap vacuum-lite" for special empty records to prevent growth of databases. Later extensions to mimic read-only behaviour of records will include proper shared read-only locking of database records, making the laccessor/lacount read-only access to the data obsolete anyway. By removing this special case and handling of lacount laccessor makes the codapath where shared read-only locking will be be implemented simpler, and frees up space in the ctdb_ltdb header for use by vacuuming flags as well as read-only locking flags.

* Add a new event "ipreallocated"Ronnie Sahlberg2010-08-301-0/+1
| | | | | | | | | | | | | | | | | This is called everytime a reallocation is performed. While STARTRECOVERY/RECOVERED events are only called when we do ipreallocation as part of a full database/cluster recovery, this new event can be used to trigger on when we just do a light failover due to a node becomming unhealthy. I.e. situations where we do a failover but we do not perform a full cluster recovery. Use this to trigger for natgw so we select a new natgw master node when failover happens and not just when cluster rebuilds happen.
