ReadOnly: After recovering all databases, make sure to clear out the tracking database used to track delegations and revoke. This is because the recovery will implicitely result in a revoke of all delegations.
ReadOnly: Add an extra flag to ctdb_call_local to specify whether we want to write the record and header back to the tdb (for example we do when performing dmaster migrations)
ReadOnly: Add functions to register CALLs to a context used to handle deferal of processing of CALL commands.
ReadOnly: Add a function to start a revoke of all delegations for a record.
ReadOnly: Add a new flag to call request packet to indicate that the client wants a readonly delegation
ReadOnly: When releasing all deferred calls that blocked during revoke of all previous delegations, add a 1 second grace/delay for any new readonly delegation requests so that the read-write fetch-lock porcess has a chance to make progress
ReadOnly: Once recovery has finished, make sure to free all revoke child processes and trigger the destructors for all deferred calls to re-queue the original packets to the input packet processing function
ReadOnly: Add processing for ReadOnly delegation requests and revoke requests to the processing loop for CALL packets we receive from different nodes.
ReadOnly: Add handlign of readonly requests readwrite requests, delegations and revoking of delegation to the processing loop for CALL requests coming in from a local client via domain socket
ReadOnly: Add a ctdb_ltdb_fetch_readonly() helper function
ReadOnly: Add clientside code to fetch readonly records
ReadOnly: Add a test tool to fetch a record, requesting a readonly delegation and lock the record once
ReadOnly: Add a test tool that requests a readonly delegation in a loop
ReadOnly: Change the update_record test tool to use the new fetchlock routine that can do either normal or readonly fetchlock
ReadOnly: When the client wants a readwrite lock but the local node is the dmaster and also have delegations active we must send a CALL to the local daemon to trigger it to revoke the delegations
ReadOnly: clear out the tracking record once a revoke is completed
ReadOnly: add description of readonly records
ReadOnly: Check the readonly flag instead of whether the tdb pointer is NULL or not
ReadOnly: Change the ctdb_db structure to keep a uint8_t for flags instead of a boolean for
ReadOnly: add a readonly flag to the getdbmap control and show the readonly setting in ctdb getdbmap output
ReadOnly: add a new control to activate readonly lock capability for a database.
ReadOnly: update the documentation about readonly locks
ReadOnly: Rename the function ctdb_ltdb_fetch_readonly() to ctdb_ltdb_fetch_with_header() since this is what it actually does.
fix some compiler warnings for the test tools
ReadOnly: revokechild_active is a list, not a context.
ReadOnly: Dont update the record header from the calling client. While it is convenient since it avoids having to create a child process from the main dameon for writing the updated record it makes the cleitn more complex.
ReadOnly DOCS: update the docs for readonly delegations to remove the passage that records are written/updated by the client
ReadOnly: fix bug writing incorrect amount of data in delegated record
ReadOnly: add readonly record lock requests to libctdb
ReadOnly: If record does not exist, upgrade to write-lock
libctdb: dont allow ctdb_writerecord() for readonly records
ReadOnly: update the loop test tool to print number of fetches per second
New version 1.2.40
ReadOnly: Do not force all normal database to READONLY.
Eventscripts: remove the horrible horrible circular reference between state and callback since these two structures do not even share the same parent talloc context.
make tdb valgrind-happy
Make KILLTCP structure a child of VNN so that it is freed at the same time
When adding ips to nodes, set up a deferred rebalance for the whole node to trigger after 60 seconds in case the normal ipreallocated is not sufficient to trigger rebalance.
Add a tunable variable to control how long we defer after a ctdb addip until we force a rebalance and try to failback addresses onto this node
Vacuuming: change default timeout to 120 seconds
READONLY: skip vacuuming or deleting records with readonly delegations.
Niceify the readonlyrecord API. Dont force clients to be exposed to the fetch_with_header function
READONLY: allow specifying the db name for setdbreadonly instead of just the hash
READONLY: when updating a remote node to revoke a delegation, make sure
READONLY: only send a control to schedule fast-vacuuming from child context iff we have a connection open to the main daemon
READONLY: readonly fetch collapse. Make sure we only keep one single readonly fetch for a record in flight at a time.
STATISTICS: add total counts for number of delegations and number of revokes
Revert "READONLY: readonly fetch collapse. Make sure we only keep one single readonly fetch for a record in flight at a time."
readonly, dont allow any kind of fast vacuum for ro delegated records
new version 1.2.41
ReadOnly: Only restrict the readonly sanity/paranoia check that only allows
new version 1.2.42
New version 1.2.43
New version 1.2.44
Add new command to find which interface is located on
When we release an ip, get the interface name from the kernel
When we find an ip we shouldnt host, just release it

root (1):
ctdbd_pid : dont assign the ctdbd_pid until we have finished startup and thus dont log warnings about 'Handling event ...' until startup has finished.
