2014-02-22  Lenz Grimmer <lenz@grimmer.com>

 - BUG#1283094: The Option "--recoveryopts" did not actually work when
   provided on the command line.

2014-02-16  Lenz Grimmer <lenz@grimmer.com>

 - BUG#1095690: The mycnf option now accepts both a file name pointing to an
   individual my.cnf file as well as a directory name like /etc/mysql to back
   up an entire configuration directory. The configuration will be stored
   in a subdirectory <prefix>-cnf-<suffix>.
 - BUG#1269096: Tar output was always verbose, even if quiet option was set.

2014-02-15  Lenz Grimmer <lenz@grimmer.com>

 - BUG#1186570: Check for the existence of the backup LV and bail out
   earlier (not when trying to create the LV snapshot)

2013-08-25  Lenz Grimmer <lenz@grimmer.com>

 - The purge action now only works for tar and local rsync archives (zbackup
   repos would be corrupted, rsnap does its own retention)

2013-08-08  Korjavin Ivan <korjavin@gmail.com>

- Added zbackup backup type

2013-06-11  Lenz Grimmer <lenz@grimmer.com>

 - Improved error handling: send out an email if mail_report_on has been
   set to "errors" and a log message with log level LOG_ERR was logged.
 - Abort and clean up if the snapshot volume could not be mounted
 - Abort and clean up if the backup creation failed
 - Exit with a non-zero return code if errorstate was set

2013-06-09  Lenz Grimmer <lenz@grimmer.com>

 - Enabled timestr() formatting sequences for snapshot volume names, to
   create snapshot names which contain a dynamic date value. This can
   be useful when thin provisioned snapshots are used as the actual backup
   by enabling the keep_snapshot option

2013-06-03  Lenz Grimmer <lenz@grimmer.com>

 - Added "thin" option to mylvmbackup.conf (default=0), to enable 
   thin provisioned LVM snapshots

2013-06-01  Lenz Grimmer <lenz@grimmer.com>

 - Added new configuration option "recoveryopts" that allows to modify
   the command line options that are passed to the MySQL instance that
   performs the InnoDB recovery (BUG#544295 and BUG#1091950)
   The current default options are "--skip-networking --skip-grant
   --bootstrap --skip-syslog --skip-slave-start" (which better
   accommodates MySQL 5.1)

2013-05-30  Lenz Grimmer <lenz@grimmer.com>

 - Merged patches from Alexandre Anriot to provide a mail reporting method
   which sends the log output via email and a new "purge" action that allows
   to only keep a defined number of backups in the backup directory

2013-03-31  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch contributed by Klaus Ethgen that removes the annoying LVM
   warnings about a leaked file descriptor (DBD:mysql does not add FD_CLOEXEC
   on the MySQL socket)

2012-12-16  Lenz Grimmer <lenz@grimmer.com>

 - BUG#1086313: mvlvmbackup lacks support for 'thin' LVM snapshots
   (Thanks to Neil Wilson for the patch)

2011-11-24  Lenz Grimmer <lenz@grimmer.com>

 - BUG#787063: Ensure to clean up temporary .pos files when the snapshot mount
   is kept, too 

2011-02-14  Lenz Grimmer <lenz@grimmer.com>

 - Applied small patch from Norbert Tretkowski: change umask to 077 before
   creating the tarball backup files to prevent them from being readable by
   everyone

2010-09-21  Lenz Grimmer <lenz@grimmer.com>

 - BUG#593220: Fixed the compressarg option for cat (removed the comment)

2010-09-09  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch contributed by Ben Bonnel to add a new configuration option
   "rsnaprsyncarg" that allows one to pass special options to the rsync process
   when using the rsnap backend.
 
2010-01-09  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch provided by Ask Bjørn Hansen to allow targets not to have a
   timestamp (e.g. for rsync targets)

2009-09-06  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.14

2009-07-02  Lenz Grimmer <lenz@grimmer.com>

 - Deleted sample precleanup.pm hook as it has potential to cause harm and
   is too specialized on a particular use case (BUG#394668)

2009-06-26  Lenz Grimmer <lenz@grimmer.com>

 - Added support for rsync via SSH (BUG#392462)
 - Fixed InnoDB recovery in case a relative path to the MySQL
   data directory is defined (BUG#38337), improved the documentation
   of relpath in the man page.

2009-06-20  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.13

2009-06-18  Lenz Grimmer <lenz@grimmer.com>

 - Fixed allowed format strings for timestamped backupdir and mountdir
   directory names
 - Updated documentation: added information about hooks as Perl modules,
   added new logerr hook to the list of available hooks, use of format
   strings for the backupdir and mountdir. Documented the fact that these
   directories are now created automatically, if they don't exist.
 - Fixed Makefile and RPM spec file to install Perl hooks (and include them
   in the distribution)
 - Removed the absolute path names to external tools, as they tend to differ
   between Linux distributions - ensure to configure $PATH correctly instead
 - Added --log-err to the startup options of the InnoDB recovery instance
   to redirect logging output to $TMP/mylvmbackup_recoverserver.err (instead
   of using the primary instance's error log file, in case it has been defined
   in my.cnf)
 
2009-06-14  Lenz Grimmer <lenz@grimmer.com>

 - Merged contributions from Matthew Boehm:
 - Added support for date/time formatted file paths for the backupdir
   and mountdir. Example: $backupdir=/path/to/%Y/%m/%d will expand to
   /path/to/2008/10/02 and backups will go in there.
 - Added support to attempt to create $backupdir and $mountdir if they do
   not exist.
 - Added support for using Perl modules as hook scripts. Module must be
   named <hook>.pm and must be a package of type <hook>.  Module must
   implement ->execute() which is called by mylvmbackup to initiate the 
   hook. It must return boolean true/false (1 or 0) on success/failure.
   ->execute() will be passed 2 parameters. The first parameter is a
   clone() of the global $dbh. This will allow hook scripts to perform
   actions on the DB using the existing connection. The second parameter
   is a string containing any messages passed to the run_hook() function.
   Module must also implement ->errmsg() which will return a string error
   message to be sent to log_msg(). This will be called by mylvmbackup
   when ->execute() returns false/0.
 - Added new hook, 'logerr'. Called by log_msg() when log severity is
   LOG_ERR. Passes $msg to hook script.

2009-06-13  Lenz Grimmer <lenz@grimmer.com>

 - Removed the bind mount of the position file directory: copy the config
   files (position record and my.cnf) into the writable snapshot directly
 - Fixed the backup backends to honor this change, fixed the rsnap plugin
   to actually include the config files as well
 - Removed some hardcoded /tmp paths with a $TMP variable
 - Removed superflous $lvm_version variable
 
2009-06-07  Lenz Grimmer <lenz@grimmer.com>

 - Made Linux LVMv2 a requirement

2009-05-07  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch by Tim Stoop: added option --keep_mount which keeps the
   snapshot mounted after the mylvmbackup run (which also implies
   --keep_snapshot)

2009-03-02  Lenz Grimmer <lenz@grimmer.com>

 - Updated all URL references to point to lenzg.net instead of lenzg.org
 - Applied small patch from Baron Schwartz to allow reading from ~/.my.cnf

2008-12-17  Lenz Grimmer <lenz@grimmer.com>

 - Added project home page URL to the --help output, added note about
   the existence of a sample config file to the man page
 - Add build date to the version string in the help output
 - Fixed check for backupdir to not require it when using rsync to a
   remote server or when not doing any backups with backuptype=none
   (Thanks to Ronald Bradford for these suggestions)

2008-11-23  Lenz Grimmer <lenz@grimmer.com>

 - Added new option "--quiet" that suppresses informal logging output
   (warnings and errors will still be printed/logged)
 - Small fixes to kjetilho's patch

2008-11-20  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch from "kjetilho" that makes mylvmbackup more robust and
   paranoid when it comes to handling errors/failures (Bug #298175)
   Now the script aborts cleanly in case of any error.

2008-10-22  Lenz Grimmer <lenz@grimmer.com>

 - Fixed error handling in case of a failed DB connection (patch submitted
   by Matthew Boehm, Bug #280989)
 - Merged changes from Alexander Skwar: Fix for Bug #278478 and implemented
   Blueprint "Improve the tar backup backend of mylvmbackup"

2008-10-01  Lenz Grimmer <lenz@grimmer.com>

 - Fixed Bug #271671: "overloading parameters does not work" by removing
   the default values for host and port from the configuration file and
   removing the unnecessary check for passing both host and socket at
   the same time. Updated documentation and configuration file comments
   accordingly.
 - Applied patch suggested by "Jonas" to fix Bug #267944: "backup returns
   successfully when snapshot creation fails"
 - Code cleanup: moved flushing of tables in a separate subroutine
   flush_tables()
 - Code cleanup: moved log messages into the respective subroutines
 - Code cleanup: use return values of subroutines instead of updating global
   variables
 - Improved some log messages to explain what was DONE or FAILED
 - Code cleanup: build up long command strings in a $command variable before
   passing it to system()
 - Renamed subroutine create_snapshot() to create_lvm_snapshot()

2008-09-25  Lenz Grimmer <lenz@grimmer.com>

 - Merged patch from Matthew Boehm: Removed old asciidoc documentation in
   favor of POD style. This removes the dependency on the external program a2x
   for creating documentation and uses the 'built-in' pod2html and pod2man
   instead. Updated the Makefile to accommodate the change.

2008-09-24  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch from Matthew Boehm to make the backup file name
   suffix configurable via a "--suffix" option. Updated the man
   page accordingly.

2008-09-23  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.11
 - Applied patch from Matt Lohier to support rsnap as a backup backend
 - Updated man page
 - Moved the list of contributors from the man page into a separate CREDITS
   file, added missing names
 - Updated the RPM spec file to include CREDITS

2008-09-03  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch from Marc Haber: added option "--keep_snapshot" that will
   skip the removal of the backup snapshot before terminating the script.
   Providing the option "--backuptype=none" will now skip creating a backup
   using the builtin backup modules. Both options provide more flexibility
   when using hooks for performing the actual backup tasks.
 - Added two new hooks: "backupsuccess" and "backupfailure" which are called
   respectively upon success of failure of the backup operation (Bug #264089)
 - Updated documentation

2008-07-18  Lenz Grimmer <lenz@grimmer.com>

 - Make sure that binaries are being found ($PATH may not include /sbin when
   called from cron), added missing entry for "lvs" to mylvmbackup.conf
   (Bug #255703)

2008-07-10  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch from Patrick Hahn: provide an option to call external
   scripts/applications (hooks) at various stages of the backup
   process. See the man page for instructions
 - Added options "--skip_hooks" to disable the execution of hooks and
   "--hooksdir" to define the location for these (default is
   /usr/share/mylvmbackup)
 - Updated documentation: added new options and instructions on how
   to use hooks
 - Updated TODO

2008-07-09  Lenz Grimmer <lenz@grimmer.com>

 - Applied patch from Robin H. Johnson: Full support for an rsync:// service
   as the backup destination. If you include any path fragments with the rsync
   module name, they must already exist!
 - Updated documentation to reflect this change

2008-06-25  Lenz Grimmer <lenz@grimmer.com>

 - The mylvmbackup source tree was moved from Subversion to Bazaar and is now
   hosted on Launchpad.net: 

2008-04-10  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.9

2008-04-09  Lenz Grimmer <lenz@grimmer.com>

 - Fixed a bug in the InnoDB recovery function: the second mysqld process
   clobbered the socket file of the primary MySQL instance
   (thanks to Alain Hoang for reporting this)
 - Updated the man page, noted some other limitations of the InnoDB recovery
   function

2008-04-04  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.8

2008-03-03  Lenz Grimmer <lenz@grimmer.com>

 - Bug fix: use the correct mysqld parameter to provide an alternative PID
   file (--pid-file instead of --pidfile) - thanks to Guillaume Boddaert and
   Jim Wilson for reporting this!
 - Added option "--skip_mycnf" to skip including a copy of the MySQL
   configuration file in the backup, added a safety check that the file
   actually exists prior to backing it up.

2007-10-27  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.7

2007-10-27  Lenz Grimmer <lenz@grimmer.com>

 - Use mktemp/mkdtemp to generate the random temporary file/directory names

2007-10-27  Robin H. Johnson <robbat2@gentoo.org>

 - Add rsync backup type. This is very useful if you want to use mylvmbackup to
   create the initial state for your slave servers.
 - Shrink the --help output by only listing common options, and referring the
   user to the manpage for further information.

2007-10-20  Robin H. Johnson <robbat2@gentoo.org>

 - Add support for a trailing argument to tar, can be used for excluding
   files.
 - Clean up variable ordering and manpage to ensure that all
   arguments/configopts are documented.
 - Do not start NDB or a replication slave when performing InnoDB recovery
 - Separate out the suffix of the tarball (Preparation for rsync and users
   that want to use bzip2 or no compression.)
 - Use a temporary suffix at the end of the tar backup file to indicate that
   it is incomplete.
 - Applied patch from Robin H. Johnson: Include the my.cnf file in the backup.
   (TODO: make this optional and check for the existence of the file before
   copying it)
 - Add the ability to run an extra FLUSH TABLES for busy databases where
   lvcreate might take a long time (and may overrun the interactivity timeout
   on the connection, losing the lock).

2007-09-13  Lenz Grimmer <lenz@grimmer.com>

 - Added option "--pidfile" to provide an alternative PID file location for
   the second server instance that is started to perform the InnoDB recovery
   on the snapshot prior to backing it up (Otherwise it may default to using
   the same pid file location that the running server uses and safe_mysqld
   will abort) - thanks to Kristian Köhntopp for making me aware of this
   problem
 - Before discarding the snapshot LV, the output of "lvs <snapshot>" is now
   printed out for diagnostics. It contains useful information like "how much
   percent of the backing store was used, which helps tuning the size of the
   snapshot LV.
 - Updated the man page, documented the new pidfile option and added a section
   with general hints

2007-07-03  Lenz Grimmer <lenz@grimmer.com>

 - Added option "--skip-flush-tables" that performs the snapshot without
   flushing the tables to disk beforehand (which is not supported by InnoDB
   tables anyway) - this would save time, as the flushing can take some time,
   depending on the buffer sizes. (Thanks to Peter Zaitsev for the suggestion)

2007-05-31  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.6
 - Updated man page and README to list all required Perl modules
   (thanks to Scott Kaminiski for pointing this out)
 - Replaced the call to the external /bin/date binary for creating
   the timestamp string with a builtin function (using Date::Format)

2007-05-07  Lenz Grimmer <lenz@grimmer.com>

 - Bumped up version number to 0.5
 - Slightly reworked Eric's patch and performed some minor code cleanup
 - Documented the InnoDB recovery option in the man page

 - Added Option "--innodb-recover", which provides an option to run InnoDB
   recovery on LVM2 snapshots (which provide write access to the device) prior
   to creating the backup archive. This speeds up resuming a MySQL instance
   from a restored backup. Also fixed a bug with the default value handling
   for command line options. In version 0.4 if a config file was specified
   default values in the script were all changed to blank. This means that
   the config file had to supply values for every variable instead of just
   the values that need to be changed from default.

 - Bumped up version number to 0.4
 - Fixed DSN string handling (thanks to Peter Zaitsev for spotting this)
 - removed a few unused configuration options from the config file (we can
   re-add them once they are really used)
 - Slightly cleaned up Robin's changes, updated the man page and help output
 - Fixed logging to the console (log levels were not printed)

2007-01-12  Robin H. Johnson <robbat2@gentoo.org>

 - Clean up option handling to load the defaults, followed by the default
   configuration file, followed by an alternative configuration file
   (specified via CLI arguments), followed by the remainder of the CLI
   arguments.
 - Do cleanups on directory inputs for spaces and trailing slashes.
 - Enforce a non-empty prefix at all times.
 - Change the capture of the position file and tarball creation to not use
   absolute paths, and instead use them relative to $mountdir.
 - Utilize a bindmount to get the position directory near the $mountdir for
   the tarball creation.
 - 'use vars' has been deprecated by upstream way back in Perl-5.6.0
   http://perldoc.perl.org/vars.html, use 'my' instead.

 - Cleaned up Fred's patch a bit: added --help output and corrected the option
   handling. Provide sane default values when no option file is used.
 - Only require SyS::Syslog if we actually use syslog for logging (less
   Perl module dependencies)
 - Slightly beefed up the console logging by printing a time stamp in front
   of the message and display "Info/Warning/Error/" according to the log
   level.
 - Removed syslog_ident and syslog_args from the command line options and
   config file (these remain hardcoded)
 - added check for hostname, if remote logging is requested
 - Updated and reformatted the help output
 - Changed the name of the default logging from "standard" to "console"
 - Added descriptions of the new logging options to the man page
 - Released as version 0.3

2006-11-23  Fred Blaise <fred.blaise@gmail.com>

 - Added functionality to use syslog for logging activity. This requires
   the Sys::Syslog Perl module.
 - Bugfix: in GetOptions, tar and umount were pointing to the mount binary.
 - Do not append a '/' to $mountdir if $prefix is empty.
 - Bugfix: Corrected variable 'date_format' back to 'datefmt'
 - Bugfix: Removed tailing slash for backupdir and mountdir in config file to
   avoid resulting double slash with unused variable
 - Bugfix: Fixed wrong section assignation of $prefix (misc, instead of lvm),
   which resulted in uninitialized value.

2006-11-23  Lenz Grimmer <lenz@grimmer.com>

 - slightly cleaned up Fred's patch, reverted using the previous default values
   and match the variables used in the config file with the command line
   options
 - Updated TODO (supporting external config files is done, thanks)
 - bumped up version number to 0.3
 - Added installing of the config file to the Makefile
 - Changed the default LVM snapshot size from 10M to 5G to match the defaults
 - Added the config file to the RPM file list
 - Changed the script to still work without the configfile, falling back to
   builtin defaults (to revert the previous behavior).
 - Started converting the man page to asciidoc for easier maintenance and
   more possibilities to convert to other formats like HTML or DocBook.
 - Renamed the man page input file, added man page building with a2x to the
   Makefile

2006-11-22  Fred Blaise <fred.blaise@gmail.com>

 - Added initial support for using an external /etc/mylvmbackup.conf
   configuration file (requiring the Config::IniFiles Perl module)

2006-11-21  Lenz Grimmer <lenz@grimmer.com>

 - Removed the START/STOP SLAVE calls (They cause problems where the box isn't
   a slave, and don't actually help anything where the box is a slave) - thanks
   to Robin H. Johnson <robbat2@gentoo.org> for reporting this and Fred Blaise
   for verifying it.

2006-11-15  Lenz Grimmer <lenz@grimmer.com>

 - Added Makefile to perform various build and installation tasks
 - Renamed the mylvmbackup source file to mylvmbackup.pl.in, which
   is turned into the mylvmbackup executable by the Makefile
 - Added RPM spec file to build RPM packages
 - Updated Version to 0.2 (now defined in the Makefile)
 - Updated INSTALL file, now one can run "make install" instead of manually
   copying the files
 - Updated TODO list
 - Released as version 0.2

2006-11-14  Lenz Grimmer <lenz@grimmer.com>

 - Documented Robin's changes in the man page, cleaned up the man page
   in general
 - Added new option: 'datefmt' that allows one to define the format of
   the date time stamp in the backup file name

2006-11-12  Robin H. Johnson <robbat2@gentoo.org>

 - General cleanup, intended to make mylvmbackup usable for distributions.
 - Add --xfs to help with using XFS snapshots (adds nouuid per LVM HOWTO)
 - Support for relative paths within the datadir LV.
 - Sane default locations for the snapshot mount point and the backup
   directory. Distributions should create /var/tmp/mylvmbackup/mnt/ and
   /var/tmp/mylvmbackup/backup/ on installation of mylvmbackup.
 - Add a prefix name for backups, to enable multiple parallel backups.
 - Add host/port/socket support for connecting to MySQL properly.
 - Give a little more output during the backup process.
 - Change the position file format to be a key/value pair style.
 - Capture the slave and master status during position capture.
 - Hidden option: 'tararg' to override the default 'cvzf' parameter to tar.
 - Hidden option: 'backuplv' to control the name of the snapshot LV.

2006-05-05  Lenz Grimmer <lenz@grimmer.com>

 - Initial version 0.1
 - Moved out of the internal BK repository, added GPL license and additional info
