Whole database lock requests can no longer be denied + because there are too many active locks - this is particularly + important for freezing databases during recovery. + +* The debug_locks.sh script locks against itself. If it is already + running then subsequent invocations will exit immediately. + +* ctdb tool commands that operate on databases now work correctly when + a database ID is given. + +* Various code fixes for issues found by Coverity. + +Important internal changes +-------------------------- + +* statd-callout has been updated so that statd client information is + always up-to-date across the cluster. This is implemented by + storing the client information in a persistent database using a new + "ctdb ptrans" command. + +* The transaction code for persistent databases now retries until it + is able to take the transaction lock. This makes the transation + semantics compatible with Samba's implementation. + +* Locking helpers are created with vfork(2) instead of fork(2), + providing a performance improvement. + +* config.guess has been updated to the latest upstream version so CTDB + should build on more platforms. + + Changes in CTDB 2.5 =================== |
