Fri Apr  2 17:03:00 UTC 2010 - jmcdonough@suse.de

- Update to version 1.0.114.
  + Lots of changes from Metze
- Update to version 1.0.113.
  + Incorrect use of dup2() could cause ctdb to spin eating 100% cpu.
- Update to version 1.0.112.
  + Revert the use of wbinfo --ping-dc as it is proving too unreliable.
  + Minor testsuite changes.
- Update to version 1.0.111.
  + Fix a logging bug when an eventscript is aborted that could cause a crash.
  + Add back cb_status that was lost in a previous commit.
- Update to version 1.0.110.
  + Metxe: fix for filedescriptor leak in the new eventscript code.
  + Rusty: fix for a crash bug in the eventscript code.
- Update to version 1.0.109.
  + Massive eventscript updates. (bz58828)
  + Nice the daemon instead of using realtime scheduler, also use mlockall() to
    reduce the risk of blockign due to paging.
  + Workarounds for valgrind when forking once for each script. Valgrind consumes
    massive cpu when terminating the scripts on virtual systems.
  + Sync the tdb library with upstream, and use the new TDB_DISALLOW_NESTING flag.
  + Add new command "ctdb dumpdbbackup"
  + Start using the new tdb check framework to validate tdb files upon startup.
  + A new framework where we can control health for individual tdb databases.
  + Fix a crash bug in the logging code.
  + New transaction code for persistent databases.
  + Various other smaller fixes.
- Update to version 1.0.108.
  + Transaction updates from Michael Adam.
  + Use the new wbinfo --ping-dc instead of -p in the eventscript for samba
    the check if winbindd is ok.
  + Add a better "process-exist" for samba so it will automatically
    reap smbd's on stopped and banned nodes to reclaim subrecords.
    This will be done a bit differently in the next release.
  + Use a statically allocated buffer for the 'first-time' capture buffer
    to reduce the pressure on malloc/free.
- Update to version 1.0.107.
  + fix for rusty to solve a double-free that can happen when there are
    multiple packets queued and the connection is destroyed before
    all packets are processed.
- Update to version 1.0.106.
  + Buildscript changes from Michael Adam
  + Dont do a full recovery when there is a mismatch detected for ip addresses,
    just do a less disruptive ip-reallocation
  + When starting ctdbd, wait until all initial recoveries have finished
    before we issue the "startup" event.
    So dont start services or monitoring until the cluster has
    stabilized.
  + Major eventscript overhaul by Ronnie, Rusty and Martins and fixes of a few
    bugs found.

-------------------------------------------------------------------
Wed Nov 19 13:39:51 CET 2009 - lmuelle@suse.de

- Update to version 1.0.105.
  + Fix a bug where we could SEGV if multiple concurrent "ctdb eventscript
    ..." are used and some of them block.
  + Monitor the daemon from the syslog child process so we shutdown cleanly
    when the main daemon terminates.
  + Add a 500k line ringbuffer in memory where all log messages are stored.
  + Add a "ctdb getlog <level>" command to pull log messages from the in
    memory ringbuffer.
  + Fixes to cifs and nfs autotests
  + Fix a bashism in 11.natgw
- Update to version 1.0.104.
  + We can now use killtcp to kill local connections for nfs so change the
    killtcp script to kill both directions of an NFS connection.
  + When using natgw, try to avoid using a UNHEALTHY node as the natgw master.
  + Fix a SEGV bug in the recent change to the eventscripts to allow the
    timeout to apply to each individual script.
  + Fix a talloc bug in teh vacuuming code that produced nasty valgrind
    warnings.
  + Set up ulimit to create core files for ctdb, and spawned processes by
    default.
  + Remove the wbinfo -t check from the startup check that winbindd is happy.
  + Enhance the test for bond devices so we also check if the sysadmin have
    disabled all slave devices using "ifdown".
- Update to version 1.0.103.
  + Dont use vacuuming on persistent databases.
  + Transaction updates to persistent databases.
  + Dont activate service automatically when installing the RPM.
  + Create a child process to send all log messages to, to prevent a hung/
    slow syslogd from blocking the main daemon. In this case, discard log
    messages instead and let the child process block.
- Update to version 1.0.102.
  + Fix for the vacuuming code.
  + Stronger tests for persistent database filename tests.
  + Improve the log message when we refuse to startup since wbinfo -t fails
    to make it easier to spot in the log.
  + Update the uptime command output and the man page to indicate that "time
    since last ..." if from either the last recovery OR the last failover.
  + Transaction updates.
- Update to version 1.0.101.
  + Create a separate context for non-monitoring events so they dont interfere
    with the monitor event.
  + Make sure to return status 0 in teh callback when we abort an event.
- Update to version 1.0.100.
  + Change eventscript handling to allow EventScriptTimeout for each
    individual script instead of for all scripts as a whole.
  + Enhanced logging from the eventscripts, log the name and the duration for
    each script as it finishes.
  + Add a check to use wbinfo -t for the startup event of samba.
  + TEMP: allow clients to attach to databases even when teh node is in
    recovery mode.
  + Dont run the monitor event as frequently after an event has failed.
  + DEBUG: in the eventloops, check the local time and warn if the time
    changes backward or rapidly forward.
  + Fix a bug where recovery master becoming unhealthy did not trigger an ip
    failover.
  + Disable the multipath script by default.
  + Automatically re-activate the reclock checking if the reclock file is
    specified at runtime. Update manpage to reflect this.
  + Add a mechanism where samba can register a SRVID and if samba unexpectedly
    disconnects, a message will be broadcasted to all other samba daemons.
  + Log the pstree on hung scripts to a file in /tmp instead of
    /var/log/messages.
  + Change ban count before unhealthy/banned to 10.
- Update to version 1.0.99.
  + Fix a SEGV in the new db priority code.
  + Eliminate a ctdb_fatal() if there is a dmaster violation detected.
  + During testing we often add/delete eventscripts at runtime. This could
    cause an eventscript to fail and mark the node unhealthy if an eventscript
    was deleted while we were listing the names. Handle the errorcode and make
    sure the node does not becomne unhealthy in this case.
  + Lower the debuglevel for the messages when ctdb creates a filedescruiptor
    so we dont spam the logs with these messages.
  + Dont have the RPM automatically restart ctdb.
  + Add a missing transaction_cancel() in the handling of persistent
    databases.
  + Treat interfaces with the anme ethX* as bond devices in 10.interfaces so
    we do the correct test for if they are up or not.
- Update to version 1.0.98.
  + Fix for the vacuuming database.
  + Create a directory where the test framework can put temporary overrides
    to variables and functions.
  + Wait a lot longer before shutting down the node when the reclock file is
    incorrectly configured, and log where it is configured.
  + Try to avoid running the "monitor" event when databases are frozen.
  + Add logging for every time we create a filedescriptor so we can trap fd
    leaks.
- Update to version 1.0.97.
  + Update onnode to allow specifying an alternative nodes file from the
    command line and also to be able to specify hostnames on the list of
    targets : onnode host1,host2,...   
- Update to version 1.0.96.
  + Add more debugging output when eventscripts have trouble. Print a 
   "pstree -p" to the log when scripts have hung.
  + Update the initscript,  only print the "No reclock file used" warning when
    we do "service ctdb start", dont also print them for all other actions.
  + When changing between unhealthy/healthy state, push a request to the
    recovery master to perform an ip reallocation instead of waiting for the
    recovery master to pull and check the state change.
  + Fix a bug in the new db-priority handling where a pre-.95 recovery master
    could no longer lock the databases on a post-.95 daemon.
  + Always create the nfs state directories during the "monitor" event.  This
    makes it easier to configure and enable nfs at runtime.
  + Forward-port a simper deadlock avoiding patch from the 1.0.82 branch. This
    is a simpler versionof the "db priority lock order" patch that went into
    1.0.95, and will be kept for a few versions until samba has been updated
    to use the functionality from 1.0.95.
- Update to version 1.0.95.
  + Add database priorities. Allow samba to set the priority of databases and
    lock the databases in priority order during recovery to avoid a deadlock
    when samba locks one database then blocks indefinitely while waiting for
    the second databaso to become locked.
  + Be aggressive and ban nodes where the recovery transaction start call
    fails.
- Update to version 1.0.94.
  + Be very aggressive and quickly ban nodes that can not freeze their
    databases.
- Update to version 1.0.93.
  + When adding an ip, make sure to update this assignment on all nodes so it
    wont show up as -1 on other nodes.
  + When adding an ip and immediately deleting it, it was possible that the
    daemon would crash accessing already freed memory.  Readjust the memory
    hierarchy so the destructors are called in the right order.
  + Add a handshake to the recovery daemon to eliminate some rare cases where
    addip/delip might cause a recovery to occur.
  + Updated onnode documenation.
  + Updates to the natgw eventscript to allow disabling natgw at runtime.
- Update to version 1.0.92.
  + Test updates and merge.
  + Add notification for "startup".
  + Add documentation for notification.
  + Fix for restarting vsftpd in the eventscript.
- Update to version 1.0.91.
  + New vacuum and repack design.
  + Add a new eventscript 01.reclock that will first mark a node unhealthy and
    later ban the node if the reclock file can not be accessed.
  + Add machinereadable output to the ctdb getreclock command.
  + Merge transaction updates.
  + In the new banning code, reset the culprit count to 0 for all nodes that
    could successfully compelte a full recovery.
  + Dont mark the recovery master as a ban culprit because a node in the
    cluster needs a recovery.  This happens naturally when using ctdb recover
    command so dont make this cause a node to be banned.
- Update to version 1.0.90.
  + Be more forgiving for eventscripts that hang during startup.
  + Fix for a banning bug in the new banning logic.

- Update to version 1.0.89
  + Make it possible to manage winbind independently of samba.
  + Add new prototype banning code
  + Overwrite the vsftpd state file instead of appending. This eliminates
    annoying errors in the log.
  + Redirect some iptables commands to dev null
  + From Michael A, explicitely set the broadcast when we takeover a public ip
  + Remove a reclock file check we no longer need
  + Skip any persistent database files ending in .bak
- Version 1.0.88
  + Add a new state for eventscripts : DISABLED.
    Add two new commands "ctdb enablescript/disablescript" to enable/disable
    eventscripts at runtime.
  + Bugfixes for TDB from rusty.
  + Merge/Port changes from upstream TDB library by rusty.

  + Add a new event "stopped" that is called when a node is stopped.
  + Documentation of the STOPPED flag and the stop/continue commands
  + Make it possible to start a node in STOPPED mode.
  + Add a new node flag : STOPPED and commands "ctdb stop" "ctdb continue"
    These commands are similar to "diasble/enable" but will also remove the 
    node from the vnnmap, while disable only fails all ip addresses over.
  + tests for NFS , CIFS by martins
  + major updates to the init script by martins
  + Send gratious arps with a 1.1 second stride instead of a 1 second stride
    to workaround interesting "features" of common linux stacks.
  + Various test enhancements from martins:

     object so that we can reparent the object in the tallic hierarchy.
  + document the ipreallocate command
  + Updates to enable/disable to use the ipreallocate command to block until 
    the following ipreallocation has completed.
  + Update the main daemon and the tools to allow debug level to be a string
    instead of an integer.
  + Update the sysconfig file to show using string literals instead of numeric
    values for the debuglevels used.
  + If no debuglevel is specific, make "ctdb setdebug" show the available 
    options.
  + When trying to allocate network packets, add explicit checks if the network
    transport has been shutdown before trying and failing, to make log messages
    easier to read. Add this extra check and logging to every plave packets are
    allocated.
- Version 1.0.86
  + Do not access the reclock at all if VerifyRecoveryLock is zero, not even
    try to probe it.
  + Allow setting the reclock file as "", which means that no reclock file at
    all should be used.
  + Document that a reclock file is no longer required, but that it is
    dangerous.
  + Add a control that can be used to set/clear/change the reclock file in the
    daemon during runtime.
  + Update the recovery daemon to poll whether a reclock file should be sued
    and if so which file at runtime in each monitoring cycle.

    reclock file.
- Version 1.0.85
  + From William Jojo : Dont use getopt on AIX
  + Make it possible to use "ctdb listnodes" also when the daemon is not running
  + Provide machinereadable output to "ctdb listnodes"
  + Dont list DELETED nodes in the ctdb listnodes output
  + Try to avoid causing a recovery for the average case when
    adding/deleting/moving an ip
  + When banning a node, drop the IPs on that node only and not all nodes.
  + Add tests for NFS and CIFS tickles
  + Rename 99.routing to 11.routing so it executes before NFS and LVS scripts
  + Increase the default timeout before we deem an unresponsive recovery daemon
    hung and shutdown
  + Reduce the reclock timout to 5 seconds
  + Spawn a child process in the recovery daemon ot check the reclock file to
    avoid blocking the process if the underlying filesystem is unresponsive
  + fix for filedescriptor leak when a child process timesout
  + Dont log errors if waitpid() returns -1
  + Onnode updates by Martins

  + When building initial vnnmap, ignode any nonexisting nodes
  + Add a new nodestate : DELETED that is used when deleting a node from an
    existing cluster.

    initscripts when restarting ctdb quickly after stopping it.
  + TDB nesting reworked.
  + Remove obsolete ipmux
  + From Flavio Carmo Junior: Add eventscript and documentation for ClamAV
    antivirus engine
  + From Sumit Bose: fix the regex in the test to handle the new ctdb
    statistics output that was recently added.
  + change the socket type we use for grauitious arps from the obsolete
    AF_INET/SOCK_PACKET to instead use PF_PACKET/SOCK_RAW.
  + Check return codes for some functions, from Sumit Bose, based on codereview
    by Jim Meyering.
  + Sumit Bose: Remove structure memeber node_list_file that is no longer used.
  + Sumit Bose: fix configure warning for netfilter.h
  + Updates to the webpages by Volker.
  + Remove error messages about missing /var/log/log.ctdb file from
    ctdb_diagnostics.sh from christian Ambach
  + Additional error logs if hte eventscript switching from dameon to client
    mode fails.
  + track how long it takes for ctdbd and the recovery daemon to perform the
    rec-lock fcntl() lock attemt and show this in the ctdb statistics output.
- Version 1.0.82
  + Update the "ctdb lvsmaster" command to return -1 on error.
  + Add a -Y flag to "ctdb lvsmaster"
  + RHEL5 apache leaks semaphores when crashing. Add semaphore cleanup to the 
    41.httpd eventscript and try to restart apache when it has crashed.
  + Fixes to some tests
  + Add a -o option to "onnode" which will redirect all stdout to a file for
    each of the nodes.
  + Add a natgw and a lvs node specifier to onnode so that we can use 
    "onnode natgw ..."
  + Assign the natgw address to lo instead of the private network so it can also
    be used where private and public networks are the same.
  + Add GPL boilerplates to two missing scripts.
  + Change the natgw prefix NATGW_ to CTDB_NATGW_
- Version 1.0.81
  + use smbstatus -np instead of smbstatus -n in the 50.samba eventscript 
    since this avoids performing an expensive traverse on the locking and brlock
    databases.
  + make ctdb automatically terminate all traverse child processes clusterwide
    associated to a client application that terminates before the traversal is
    completed.
  + From Sumit Bose : fixes to AC_INIT handling.
  + From Michael Adam, add Tridge's "ping_pong" tool the the ctdb distro since 
    this is very useful for testing the backend filesystem.
  + From Sumit bose, add support for additional 64 bit platforms.
  + Add a link from the webpage to Michael Adams SambaXP paper on CTDB.
- Version 1.0.80
  + change init shutdown level to 01 for ctdb so it stops before any of the
    other services
  + if we can not pull a database from a remote node during recovery, mark that
    node as a culprit so it becomes banned
  + increase the loglevel when we volunteer to drop all ip addresses after
    beeing in recovery mode for too long. Make this timeout tuneable with
    "RecoveryDropAllIPs" and have it default to 60 seconds
  + Add a new flag TDB_NO_NESTING to the tdb layer to prevent nested
    transactions which ctdb does not use and does not expect. Have ctdb set
    this flag to prevent nested transactions from occuring.
  + dont unconditionally kill off ctdb and restrat it on "service ctdb start".
    Fail "service ctdb start" with an error if ctdb is already running.
  + Add a new tunable "VerifyRecoveryLock" that can be set to 0 to prevent the
    main ctdb daemon to verify that the recovery master has locked the reclock
    file correctly before allowing it to set the recovery mode to active.
  + fix a cosmetic bug with ctdb statistics where certain counters could become
    negative.

  + Use -q instead of >/dev/null for grep to enhance readability of the
    scripts from Michael Adam.
  + Update to the "ctdb recover" command. This command now block until the
    has completed. This makes it much easier to use in scripts and avoids
    the common workaround :
       ctdb recover
       ... loop while waiting for recovery completes ...
       continue ...
  + Add a CTDB_TIMEOUT variable. If set, this variable provides an automatic
    timeout for "ctdb <command>", similar to using -T <timeout>
  + Set a unique errorcode for "ctdb <command>" when it terminates due to a 
    timeout so that scripts can distinguish between a hung command and what was
    just a failure.
  + Update "ctdb ban/unban" so that if the cluster is in recovery these commands
    blocks and waits until after recovery is complete before the perform the
    ban/unban operation. This is necessary since the recovery process can cause
    nodes to become automatically unbanned.
  + Update "ctdb ban/unban" to block until the recovery that will follow shortly
    after this command has completed.
    This makes it much easier to use in scripts and avoids the common
    workaround :
       ctdb ban/unban
       ... loop while waiting for recovery completes ...
       continue ...
  + Bugfix for the new flags handling in 1.0.67. Abort and restart monitoring
    if we failed to get proper nodemaps from a remote node instead of
    dereferencing a null pointer.
  + If ctdbd was explicitely started with the '--socket' argument, make
    ctdbd automatically set CTDB_SOCKET to the specified argument.
    This ensures that eventscripts spawned by the ctdb daemon will default to
    using the same socket and talk to the correct daemon.
    This primarily affects running multiple daemons on the same host and where 
    you want each instance of ctdb daemons have their eventscripts talk to the
    "correct" daemon.
  + Update "ctdb ping" to return an error code if the ping fail so that it
    can be used in scripts.
  + Update to how to synchronize management of node flags across the cluster.

-----------------------------------------------------------------
Thu Dec 3 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.67
  + Add a document describing the recovery process.
  + Fix a bug in "ctdb setdebug" where it would refuse to set a negative
    debug level.
  + Print the list of literals for debug names if an invalid one was given
    to "ctdb setdebug"
  + Redesign how "ctdb reloadnodes" works and reduce the amont of tcp teardowns
    used during this event.
  + Make it possible to delete a public ip from all nodes at once using
    "ctdb delip -n all"

-----------------------------------------------------------------
Mon Nov 24 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.66
  + Allow to change the recmaster even when we are not frozen.
  + Remove two redundant SAMBA_CHECK variables from the sysconf example
  + After a node failure it can take very long before some lock operations
    ctdb needs to perform are allowed/works with gpfs again. Workaround this
    by treating a hang/timeout as success.
  + Dont override CTDB_BASE is fet in the shell already
  + Always send keepalive packets regardless of whether the link is idle or not.
  + Rewrite the disable/enable flag update logic to prevent a race between 
    "ctdb disable/enable" and the recovery daemon when updating the flags to 
    all nodes.

-----------------------------------------------------------------
Thu Nov 13 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.65
  + Update the sysconfig example: The default debug level is 2 (NOTICE) and not
    0 (ERROR)
  + Add support for a CTDB_SOCKET environment variable for the ctdb command
    line tool. If set, this overrides the default socket the ctdb tool will
    use.
  + Add logging of high latency operations.

-----------------------------------------------------------------
Mon Oct 22 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.64
  + Add a context and a timed event so that once we have been in recovery for
    too long we drop all public addresses.

-----------------------------------------------------------------
Mon Oct 20 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.63
  + Remove logging of "periodic cleanup ..." in 50.samba
  + When we reload a nodes file, we must detect this and reload the file also
    in the recovery daemon before we try to dereference somethoung beyond the
    end of the nodes array.

-----------------------------------------------------------------
Thu Oct 16 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.62
  + Allow multiple eventscritps using the same prefix number.
    It is undefined which order scripts with the same prefix will execute in.

-----------------------------------------------------------------
Wed Oct 15 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.61
  + Use "route add -net" instead of "ip route add" when adding routes in
    99.routing
  + lower the loglevel os several debug statements
  + check the status returned from ctdb_ctrl_get_tickles() before we try to
    print them out to the screen.
  + install a new eventscript 20.multipathd whoich can be used to monitor that
    multipath devices are healthy

-----------------------------------------------------------------
Wed Oct 15 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.60
  + Verify that nodes we try to ban/unban are reachable and print an error
    othervise.
  + Update the client and server sides of TAKEIP/RELEASEIP/GETPUBLICIPS and
    GETNODEMAP to fall back to the old style ipv4-only controls if the new
    ipv4/ipv6 controls fail. This allows an ipv4/v6 enabled ctdb daemon to
    interoperate with earlier ipv4-only versions of the daemons.
  + From Mathieu Parent : log debian systems log the package versions in ctdb
    diagnostics
  + From Mathieu Parent : specify logdir location for debian (this patch was
    later reversed)
  + From Michael Adams : allow # comments in nodes/public_addresses files

-----------------------------------------------------------------
Tue Oct 7 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.59
  + Updated "reloadnodes" logic. Instead of bouncing the entire tcp layer it
    is sufficient to just close and reopen all outgoing tcp connections.
  + New eventscript 99.routing which can be used to re-attach routes to public
    interfaces after a takeip event. (routes may be deleted by the kernel when
    we release an ip)
  + IDR tree fix from Jim Houston
  + Better handling of critical events if the local clock is suddenly changed
    forward by a lot.
  + Fix three slow memory leaks in the recovery daemon
  + New ctdb command : ctdb recmaster   which prints the pnn of the recmaster
  + Onnode enhancements from Martin S : "healthy" and "connected" are now
    possible nodespecifiers
  + From Martin S : doc fixes
  + lowering some debug levels for some nonvital informational messages
  + Make the daemon daemon monitoring stronger and allow ctdbd to detect a hung
    recovery daemon.
  + From C Cowan : patches to compile ipv6 under AIX
  + zero out some structs to keep valgrind happy

-----------------------------------------------------------------
Wed Aug 27 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.58
  + revert the name change tcp_tcp_client back to tcp_control_tcp so
    samba can build.
  + Updates to the init script from Abhijith Das <adas@redhat.com>

-----------------------------------------------------------------
Mon Aug 25 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.57
  + initial support for IPv6

-----------------------------------------------------------------
Mon Aug 11 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.56
  + fix a memory leak in the recovery daemon.

-----------------------------------------------------------------
Mon Aug 11 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.55
  + Fix the releaseip message we seond to samba.

-----------------------------------------------------------------
Fri Aug 8 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.54
  + fix a looping error in the transaction code
  + provide a more detailed error code for persistent store errors
    so clients can make more intelligent choices on how to try to recover

-----------------------------------------------------------------
Thu Aug 7 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.53
  + Remove the reclock.pnn file   it can cause gpfs to fail to umount
  + New transaction code

-----------------------------------------------------------------
Mon Aug 4 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.52
  + Send an explicit gratious arp when starting sending the tcp tickles.
  + When doing failover, issue a killtcp to non-NFS/non-CIFS clients
    so that they fail quickly. NFS and CIFS already fail and recover 
    quickly.
  + Update the test scripts to handle CTRL-C to kill off the test.

-----------------------------------------------------------------
Mon Jul 28 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.51
  + Strip off the vlan tag from bond devices before we check in /proc
    if the interface is up or not.
  + Use testparm in the background in the scripts to allow probing
    that the shares do exist.
  + Fix a bug in the logging code to handle multiline entries better
  + Rename private elements from private to private_data

-----------------------------------------------------------------
Fri Jul 18 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.50
  + Dont assume that just because we can establish a TCP connection
    that we are actually talking to a functioning ctdb daemon.
    So dont mark the node as CONNECTED just because the tcp handshake
    was successful.
  + Dont try to set the recmaster to ourself during elections for those
    cases we know this will fail. To remove some annoying benign but scary
    looking entries from the log.
  + Bugfix for eventsystem for signal handling that could cause a node to
    hang.

-----------------------------------------------------------------
Thu Jul 17 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.49
  + Update the safe persistent update fix to work with unpatched samba
    servers.

-----------------------------------------------------------------
Thu Jul 17 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.48
  + Update the spec file.
  + Do not start new user-triggered eventscripts if we are already
    inside recovery mode.
  + Add two new controls to start/cancel a persistent update.
    A client such as samba can use these to tell ctdbd that it will soon
    be writing directly to the persistent database tdb file. So if
    samba is -9ed before it has eitehr done the persistent_store or
    canceled the operation, ctdb knows that the persistent databases
    'may' be out of sync and therefore a full blown recovery is called for.
  + Add two new options :
    CTDB_SAMBA_SKIP_CONF_CHECK and CTDB_SAMBA_CHECK_PORTS that can be used
    to override what checks to do when monitoring samba health.
    We can no longer use the smbstatus, net or testparm commands to check
    if samba or its config is healthy since these commands may block
    indefinitely and thus can not be used in scripts.

-----------------------------------------------------------------
Fri Jul 11 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.47
  + Fix a double free bug where if a user striggered (ctdb eventscript)
    hung and while the timeout handler was being processed a new user
    triggered eventscript was started we would free state twice.
  + Rewrite of onnode and associated documentation.

-----------------------------------------------------------------
Thu Jul 10 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.46
  + Document both the LVS:cingle-ip-address and the REMOTE-NODE:wan-accelerator
    capabilities.
  + Add commands "ctdb pnn", "ctdb lvs", "ctdb lvsmaster".
  + LVS improvements. LVS is the single-ip-address mode for a ctdb cluster.
  + Fixes to supress rpmlint warnings
  + AXI compile fixes.
  + Change \s to [[:space:]] in some scripts. Not all RHEL5 packages come
    with a egrep that handles \s   even same version but different arch.
  + Revert the change to NFS restart. CTDB should NOT attempt to restart
    failed services.
  + Rewrite of the waitpid() patch to use the eventsystem for handling
    signals.

-----------------------------------------------------------------
Tue Jul 8 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.45
  + Try to restart the nfs service if it has failed to respond 3 times in a row.
  + waitpid() can block if the child does not respond promptly to SIGTERM.
    ignore all SIGCHILD signals by setting SIGCHLD to SIG_DEF.
    get rid of all calls to waitpid().
  + make handling of eventscripts hanging more liberal.
    only consider the script to have failed and making the node unhealthy
    IF the eventscript terminated wiht an error
    OR the eventscript hung 5 or more times in a row

-----------------------------------------------------------------
Mon Jul 7 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.44
  + Add a CTDB_VALGRIND option to /etc/sysconfig/ctdb to make it start ctdb
    under valgrind. Logs go to /var/log/ctdb_valgrind.PID
  + Add a hack to show the control opcode that caused uninitialized data
    in the valgrind output by encoding the opcode as the line number.
  + Initialize structures and allocated memory in various places in
    ctdb to make it valgrind-clean and remove all valgrind errors/warnings.
  + If/when we destroy a lockwait child, also make sure we cancel any pending
    transactions
  + If a transaction_commit fails, delete/cancel any pending transactions and
    return an error instead of calling ctdb_fatal()
  + When running ctdb under valgrind, make sure we run it with --nosetsched
    and also ensure that we do not use mem-mapped i/o when accessing the
    tdb's.
  + zero out ctdb->freeze_handle when we free/destroy a freeze-child.
    This prevent a heap corruption/ctdb crash bug that could trigger
    if the freeze child times out.
  + we dont need to explicitely thaw the databases from the recovery daemon
    since this is done implicitely when we restore the recovery mode back to
    normal.
  + track when we start and stop a recovery. Add the 'time it took to complete
    the recovery' to the 'ctdb uptime' output.
    Ensure by tracking the start/stop recovery timestamps that we do not
    check that the ip allocation is consistend from inside the recovery daemon
    while a different node (recovery master) is performing a recovery.
    This prevent a race that could cause a full recovery to trigger if the
    'ctdb disable/enable' commands took very long.
  + The freeze child indicates to the master daemon that all databases are
    locked by writing data to the pipe shared with the master daemon.
    This write sometimes fail and thus the master daemon never notices that
	 the databases are locked cvausing long timeouts and extra recoveries.
    Check that the write is successful and try the write again if it failed.
  + In each node, verify that the recmaster have the right node flags for us
    and force a push of our flags to the recmaster if wrong.

-----------------------------------------------------------------
Tue Jul 1 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.43
  + Updates and bugfixes to the specfile to keep rpmlint happy
  + Force a global flags update after each recovery event.
  + Verify that the recmaster agrees with our node flags and update the
    recmaster othervise.
  + When writing back to the parent from a freeze-child across the pipe, loop
    over the write in case the write failed with an error othervise the parent
    will never be notified tha the child has completed the operation.
  + Automatically thaw all databases when recmaster marks us as being in
    normal mode instead of recovery mode.

-----------------------------------------------------------------
Fri Jun 13 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.42
  + When event scripts have hung/timedout more than EventScriptBanCount times
    in a row the node will ban itself.
  + Many updates to persistent write tests and the test scripts.

-----------------------------------------------------------------
Wed May 28 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.41
  + Reactivate the safe writes to persistent databases and solve the
    locking issues. Locking issues are solved the only possible way,
    by using a child process to do the writes.  Expensive and slow but... . 

-----------------------------------------------------------------
Tue May 27 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.40
  + Read the samba sysconfig file from the 50.samba eventscript
  + Fix some emmory hierarchical bugs in the persistent write handling

-----------------------------------------------------------------
Thu May 22 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.39
  + Moved a CTDB_MANAGES_NFS, CTDB_MANAGES_ISCSI and CTDB_MANAGES_CSFTPD
    into /etc/sysconfig/ctdb
  + Lowered some debug messages to not fill the logfile with entries
    that normally occur in the default configuration.

-----------------------------------------------------------------
Fri May 16 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.38
  + Add machine readable output support to "ctdb getmonmode"
  + Lots of tweaks and enhancements if the event scripts are "slow"
  + Merge from tridge: an attempt to break the chicken-and-egg deadlock that
    net conf introduces if used from an eventscript.
  + Enhance tickles so we can tickle an ipv6 connection.
  + Start adding ipv6 support : create a new container to replace sockaddr_in.
  + Add a checksum routine for ipv6/tcp
  + When starting up ctdb, let the init script do a tdbdump on all
    persistent databases and verify that they are good (i.e. not corrupted).
  + Try to use "safe transactions" when writing to a persistent database
    that was opened with the TDB_NOSYNC flag. If we can get the transaction
    thats great, if we cant  we have to write anyway since we cant block here.

-----------------------------------------------------------------
Mon May 12 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.37
  + When we shutdown ctdb we close the transport down before we run the 
    "shutdown" eventscripts. If ctdb decides to send a packet to a remote node
    after we have shutdown the transport but before we have shutdown ctdbd
    itself this could lead to a SEGV instead of a clean shutdown. Fix.
  + When using the "exportfs" command to extract which NFS export directories
    to monitor,  exportfs violates the "principle of least surprise" and
    sometimes report a single export line as two lines of text output
    causing the monitoring to fail.

-----------------------------------------------------------------
Fri May 9 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.36
  + fix a memory corruption bug that could cause the recovery daemon to crash.
  + fix a bug with distributing public ip addresses during recovery.
    If the node that is the recovery master did NOT use public addresses,
    then it assumed that no other node in the cluster used them either and
    thus skipped the entire step of reallocating public addresses.

-----------------------------------------------------------------
Wed May 7 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.35
  + During recovery, when we define the new set of lmasters (vnnmap)
    only consider those nodes that have the can-be-lmaster capability
    when we create the vnnmap. unless there are no nodes available which
    supports this capability in which case we allow the recmaster to
    become lmaster capable (temporarily).
  + Extend the async framework so that we can use paralell async calls
    to controls that return data.
  + If we do not have the "can be recmaster" capability, make sure we will
    lose any recmaster elections, unless there are no nodes available that
    have the capability, in which case we "take/win" the election anyway.
  + Close and reopen the reclock pnn file at regular intervals.
    Make it a non-fatal event if we occasionally fail to open/read/write
    to this file.
  + Monitor that the recovery daemon is still running from the main ctdb
    daemon and shutdown the main daemon when recovery daemon has terminated.
  + Add a "ctdb getcapabilities" command to read the capabilities off a node.
  + Define two new capabilities : can be recmaster and can be lmaster
    and default both capabilities to YES.
  + Log denied tcp connection attempts with DEBUG_ERR and not DEBUG_WARNING

-----------------------------------------------------------------
Thu Apr 24 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.34
  + When deleting a public ip from a node, try to migrate the ip to a
    different node first.
  + Change catdb to produce output similar to tdbdump
  + When adding a new public ip address, if this ip does not exist yet in the
    cluster, then grab the ip on the local node and activate it.
  + When a node disagrees with the recmaster on WHO is the recmaster, then
    mark that node as a recovery culprit so it will eventually become banned.
  + Make ctdb eventscript support the -n all argument.

-----------------------------------------------------------------
Thu Apr 10 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.33
  + Add facilities to include site local adaptations to the eventscript by
    /etc/ctdb/rc.local which will be read by all eventscripts.
  + Add a "ctdb version" command.
  + Secure the domain socket with proper permissions from Chris Cowan
  + Bugfixes for AIX from Chris Cowan

-----------------------------------------------------------------
Wed Apr 02 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.32
  + Add a control to have a node execute the eventscripts with arbitrary
    command line arguments.
  + Add a control "rddumpmemory" that will dump the talloc memory allocations
    for the recovery daemon.
  + Decorate the talloc memdump to produce better and easier memory leak
    tracking. 
  + Update the RHEL5 iscsi tgtd scripts to allow one iscsi target for each
    public address.
  + Add two new controls "addip/delip" that can be used to add/remove public
    addresses to a node at runtime. After using these controls a "ctdb
    recover" if required to make the changes take.
  + Fix a couple of slow memory leaks.

-----------------------------------------------------------------
Tue Mar 25 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.31
  + Add back controls to disable/enable monitoring on a node.
  + Fix a memory leak where we used to attach CALL data to the ctdb structure
    when performing a local call. Memory which would be lost if the call was
    aborted.
  + Reduce the loglevel for the log output when someone connects to a non
    public ip address for samba.
  + Redo and optimize the vacuuming process to send only one control to each
    other node containing all records to be vacuumed instead of one control
    per node per record.

-----------------------------------------------------------------
Tue Mar 04 12:00:00 CEST 2008 - samba@samba.org

- Version 1.0.30
  + Update documentation cor new commands and tuneables
  + Add machinereadable output to the ip,uptime and getdebug commands
  + Add a moveip command to manually failover/failback public ips
  + Add NoIPFallback tuneable that prevents ip address failback
  + Use file locking inside the CFS as alternative to verify when other nodes
   Are connected/disconnected to be able to recover from split network
  + Add DisableWhenUnhealthy tunable
  + Add CTDB_START_AS_DISABLED sysconfig param
  + Add --start-as-disabled flag to ctdb
  + Add ability to monitor for OOM condition
