2009-11-05s3: Add parameter "ctdb timeout"Volker Lendecke2-4/+21
When something in the cluster blocks, it can happen that we wait indefinitely long for ctdb, just adding to the blocking condition. In theory, nothing should block, but as someone said "In practice the difference between theory and practice is larger than in theory". This adds a timeout parameter in seconds, after which we stop waiting for ctdb and panic.

2009-11-03s3: Remove debug_ctx()Volker Lendecke2-18/+3
smbd just crashed on me: In a debug message I called a routine preparing a string that itself used debug_ctx. The outer routine also used it after the inner routine had returned. It was still referencing the talloc context that the outer debug_ctx() had given us, which the inner DEBUG had already freed.

node. In ctdb_transaction_commit(), when the trans2_commit control fails, there is a race condition in the 1 second sleep between the local transaction_cancel and the call to ctdb_replay_transaction(): The database is not locked, and neither is the transaction_lock record. So another client can start and possibly complete a new transaction in this gap, but only on the same node: The locking of the transaction_lock record on a different node which involves migration of the record to the other node has been disabled by introduction of the transaction_active flag on the db which closes precisely this gap from the start of the commit until the call to TRANS2_FINISH or TRANS2_ERROR. But this mechanism does not cover the case where a process on the same node tries to start a transaction: There is no obstacle to locking the transaction_lock record because the record does not need to be migrated. This commit closes this race condition in ctdb_transaction_fetch_start() by using the new ctdb_ctrl_transaction_active() call to ask the local ctdb daemon whether it has a transaction running on the database. If so, the check is repeated until the running transaction is done. This does introduce an additional call to the local ctdbd when starting transactions, but it does close the (hopefully) last race condition. Michael

2009-11-03s3:dbwrap_ctdb: fix a race in starting concurrent transactions on a single nodeMichael Adam1-0/+25
There are two races in concurrent transactions on a single node. One in starting a transaction and one with replay during commit. This commit closes the first race by storing the client pid in the transaction-lock record and comparing the stored pid against its own pid after releasing the lock and refetching the record inside the transaction.

2009-09-06Fix bug 6673 - smbpasswd does not work with "unix password sync = yes".Jeremy Allison1-17/+25
Revert change from 3.3 -> 3.4 with read_socket_with_timeout changed from sys_read() to sys_recv(). read_socket_with_timeout() is called with non-fd's (with a pty in chgpasswd.c and with a disk file in lib/dbwrap_file.c via read_data()). recv works for the disk file, but not the pty. Change the name of read_socket_with_timeout() to read_fd_with_timeout() to make this clear (and add comments). Jeremy.
