	Avoid importing barman.utils module twice

2017-01-03  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Make retry hook script options global (bugfix)

2016-12-27  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Update the ChangeLog file

2016-12-26  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Release 2.1a1

2016-12-21  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add PostgreSQL 10 versioning scheme compatibility
	Fix #73

	Exclude extraneous files during tablespace copy
	PostgreSQL stores the tablespace data in a directory defined in the
	PostgreSQL source as:

	    "PG_" PG_MAJORVERSION "_" CATALOG_VERSION_NO

	The CATALOG_VERSION_NO is not easy to retrieve, so we copy

	    "PG_" + PG_MAJORVERSION + "_*"

	It could select some spurious directory if a development or a beta
	version have been used, but it's good enough for a production system
	as it filters out other major versions.

	Fix #74

2016-12-20  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Align the list of excluded files to pg_basebackup
	Fixes #72

2016-12-18  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Return failure when 'barman get-wal' command is used on inactive servers
	The 'barman get-wal' command is meant to be used used as PostgreSQL's
	restore_command, so it must succeed only if the target WAL file has
	been actually returned.

2016-12-17  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add last archived WAL info to diagnose output
	Show in diagnose the last archived WAL per timeline

	switch-xlog --archive waits for the closed WAL file
	Modify the switch-xlog --archive behaviour to wait for the specific WAL
	file, instead of a generic one. This is faster and it avoids possible
	issues when a higher timeline is present in the archive.

2016-12-03  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add --archive and --archive-timeout options to switch-xlog command
	Improve the switch-xlog command adding the --archive and
	--archive-timeout options.

	The --archive option will start an archiver process for the selected
	server, and will wait for 30 seconds for a new xlog to be archived.

	The --archive-timeout TIMEOUT will allow the user to increase or
	decrease the number of seconds the archiver process will wait
	for the archival of a new xlog file, before exiting.

2016-11-26  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Make streaming application name options global
	Make both 'streaming_archiver_name' and 'streaming_backup_name'
	global options, as per documentation. Bugfix.

	Fixes #57

	Fix how barman behave when a compressed history files is found.

	Fixes: #66

	Avoid dereferencing symlinks in pg_tblspc when preparing recovery
	This commit fixes a bug triggered by the presence of a broken tablespace
	symlink in the target pg_tblspc directory when recovery starts.

	Fixes: #55

2016-10-06  Martin Swiech  <martin.swiech@zonky.cz>

	Fix comparation of last archiving failure
	Compare the time of last failure instead of the WAL name to detect
	archiving failures.

	Closes: #40, #58

2016-11-13  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Avoid failing recovery if postgresql.conf is not writable
	Fixes: #68

2016-11-08  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Add start time and execution time to delete output
	Improve the output of `barman delete` command by adding some execution
	time statistics.

	Additionally, the utility function that prints human readable time deltas
	has been improved to correctly handle a wider range of values.

	Closes #67

2016-10-26  Ian Barwick  <ian@2ndquadrant.com>

	Change references from non-existent `path` option to `path_prefix`

2016-10-28  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Exclude files within pg_replslot from backups
	Thanks to Magnus Hagander for reporting the issue.

	Ref: https://www.postgresql.org/docs/current/static/continuous-archiving.html#BACKUP-LOWLEVEL-BASE-BACKUP-DATA

	Fixes #65

2016-10-20  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

2016-10-17  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Fix output of the replication-status command.
	The replication-status command used to emit an exception in some
	PostgreSQL releases, due to the different structure of the
	`pg_stat_replication` view.

	This patch fixes the issue checking for the existence of the fields
	before writing them to the output.

	Fixes #56

2016-10-11  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Move isort configuration in setup.cfg

	Add a note in docs about concurrent backup for 9.6

2016-09-30  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Split the logic of the copy method in CopyController
	This patch creates an analisys phase and a copy phase. the analisys
	phase is responsible for the preparation of the list of files that we
	want to copy. The copy phase is responsible for the execution of the
	actual copy using rsync.

2016-10-02  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Fix level of section about WAL verification

2016-09-27  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

2016-09-23  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Improve documentation of get-wal command
	This patch improves the documentation of the get-wal command for the
	local recovery, specifying that the command must be executed as `barman`
	user and not as the user which is running the PostgreSQL server.
	It also includes details about the barman-wal-restore command.

2016-09-23  Gabriele Bartolini  <gabriele.bartolini@2ndquadrant.it>

2016-09-20  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Set version to 2.0b1

	Remove the quickstart guide
	At the moment, it is an empty document. It may be reintroduced later.

2016-09-20  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Improve configurantion error message
	The configuration error message raised when a parameter has an invalid
	value was not telling the wrong value but only the key.

	This patch improves the error message in that case.

2016-09-16  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Add troubleshooting section to manual

2016-09-16  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Improve "Features in detail" section

2016-09-19  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Avoid logging tracebacks in case of expected failures
	There was a few places in the code where an expected error was producing
	a traceback in the logs. They have been replaced with a simple error
	output.

2016-09-16  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Integrate barman-wal-restore in barman recovery
	During a remote restore, use the barman-wal-restore command instead of
	calling `barman get-wal` on the remote machine. It requires the
	barman-cli package to be installed on the target server.

	Force special tox environments to use a specific Python version
	Use Python 2.7 in the 'flake8' environment, because it doesn't work with
	Python 2.6.

	Use Python 2.6 in the 'minimal' envorinment, because it doesn't work
	with Python 3.x due to the presence of Python-2-only modules.

	Enable the minimal target in Travis-CI again, as it was failing due to
	the default Python version used there (Python 3.5).

2016-09-19  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Fix wrongly named database parameter in configuration examples
	Thanks to Abhijit Menon-Sen <ams@2ndQuadrant.com> who found it.

2016-09-14  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	This patch complete the section "general commands" inside the Barman
	manual.

2016-09-13  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Add the "setup new server" documentation section
	This patch complete the work on the "Setup of a new server in Barman"
	documentation section.

2016-09-13  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Make sure 'dbname' parameter is not set for streaming connections
	Also fix an issue in the parse_dsn method, many thanks to
	Théophile Helleboid <chtitux@gmail.com> for reporting it.

2016-09-15  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Fix flake8 plugin versions

2016-09-13  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Make sure path_prefix is honored in every Command subclass
	Commit ad8002745326fe20a2c4ce2a5e9115a26c5a5f49 contains a typo
	so it was not working at all. The typo is fixed in this commit.

2016-09-13  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Pass `--no-password` option to pg_basebackup and pg_receivexlog
	Barman will never send any password through the pg_basebackup or
	pg_receivexlog standard input channel. Invoking them with the
	`--no-password` option will produce a cleaner error message in case of
	authentication failure.

	Modify tests accordingly.

2016-09-12  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Improve the warning message for configuration files outside PGDATA
	Now the `backup_method=postgres` code emits the warning message for
	configuration files that are located outside PGDATA only when that's
	the actual case.

2016-09-12  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Moved barman-wal-restore in barman-cli project

2016-09-12  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Enable `show-server` command on inactive or disabled servers

2016-09-09  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Disable minimal tox env on travis-ci as it doesn't work on py35

	Update the ChangeLog file

	Prepare release 2.0a1

	Run minimal and flake8 tox envs in travis-ci

2016-09-09  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Fix flake8 error

2016-08-26  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	First stub of documentation for 2.0
	This is a first attempt to change the documentation in Barman,
	which creates two artifacts: a manual and a quickstart guide.

	The work is currently incomplete, but it is ok for a first
	alpha release, given that all required information from a
	technical point of view is in man pages.

	The reason for this is that now Barman does not have a sequential
	installation procedure, but different options for backup and
	WAL archiving that produce several possibile combinations of
	setups.

2016-09-09  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Set last supported version by argh for Python 2.x
	Add minimal checks in Tox

2016-09-09  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Release notes for 2.0a1

2016-09-09  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Rename barman-wal-restore.py to barman-wal-restore

2016-09-09  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Fix exception in barman check
	Barman check raise an exception when streaming_archiver is on and
	streaming_conninfo is not configured.

	This patch controls if the streaming connection is correctly configured
	before checking the pg_basebackup compatibility, removing the exception
	cause.

2016-09-09  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Remove unit test dependency on environment
	Previously unit tests were failing the $USER environment variable was
	not defined. This patch removes this requirement.

2016-09-08  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Make sure path is used in every Command class

	Switch xlog after a concurrent backup
	For a backup to be usable, all the XLOG files written between the backup
	start and the backup end must be archived.

	This patch makes PostgreSQL switch the current XLOG file after a
	concurrent backup either using rsync or streaming backup mode, in this
	way the WAL file containing the backup end position will be archived as
	soon as possible.

2016-09-07  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Add retry support when `backup_method=postgres`
	Modify the backup executor to handle the retry of a streaming
	backup with pg_basebackup (`backup_method=postgres`).
	Between every retry attempt, the PGDATA and the directories that
	contain the tablespaces are removed. Therefore, subsequent
	backup attempts restart from scratch.

2016-09-07  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Fix E303 too many blank lines (flake8)

2016-09-07  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Support /etc/barman.d in rpm packaging

2016-09-01  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Redesign retry logic for backup and recovery
	The CommandWrapper class is now responsible to specifically
	design the logic of a retry operation in case of failure.

	Previously, retry was managed at an outer level, by the
	backup manager and the executor classes.

	With this new approach, every single command can now develop its
	own retry logic.

2016-09-05  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Force `archiver=on` when no archiver is active.
	This is a back-compatibility feature that will be kept
	in Barman for a few releases, and mitigate the upgrade
	to version 2.0 (which requires explicit setting of
	an archiving method - before, `archiver` was `on` by default)

2016-09-05  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Change 'wal_level' to 'replica' in unit tests

2016-08-29  Ian Barwick  <ian@2ndquadrant.com>

	Enable barman-wal-restore.py to pass -c/--config to Barman
	This enables barman-wal-restore.py to be used if the Barman
	server uses a non-default configuration file.

2016-09-02  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Add slot name to `replication-status` (PostgreSQL 9.5+)

	Handle PostgresConnectionError exception differently
	Changed the way PostgresConnectionError works, in order
	to be more easily used in 'check' methods for both
	standard and streaming connection purposes.

	Specified also a new exception (PostgresAppNameError).

2016-09-01  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Remove any reference to Rsync.smart_copy()
	Remove the smart copy logic from the command wrappers module,
	as it is now part of RsyncCopyController.

	Support 9.6 syntax for `synchronous_standby_names`

2016-09-01  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Cosmetic changes in recovery_executor.py
	Renamed also some methods as they are private

2016-08-30  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Introduce the CopyController module for recovery
	This patch introduces the use of the RsyncCopyController
	inside the recovery_executor.py module.

2016-08-31  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Add Config.get_bwlimit() public method
	Move the private method _bwlimit() from RsyncBackupExecutor
	class into Config, and rename it into get_bwlimit().

2016-08-30  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Add status() method for archiver classes

2016-08-30  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add StreamingWalArchiver._is_synchronous()
	Make code clearer and easier to read by encapsulating
	checks for synchronous replication in a separate method
	of the StreamingWalArchiver class. Make code more resilient
	by checking that PostgreSQL connection is working.

2016-08-25  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Introduce the CopyController module for backup
	This patch adds a new module called copy_controller.py.

	The new module is responsible for containing the logic of
	a physical copy of for a backup, starting with basic
	rsync support.

	This patch is a refactor of the existing code, with
	no additional functionality yet. Only backup executor
	is using this class for now.

2016-08-30  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Fix exception in 'check' when postgres is unreachable
	The check method of PostgresBackupExecutor and ConcurrentBackupStrategy
	objects were raising an exception if PostgreSQL connection was not
	working.

	This commit fixes this behaviour by correctly handling this case.

2016-08-26  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Set default value of 'archiver' to 'off'
	This is a milestone in Barman's history as it
	removes the need for standard WAL archiving through
	the `archive_command` configuration option in
	PostgreSQL (even though it is still recommended
	to use it in conjunction with WAL streaming, for
	more robust architectures).

	**IMPORTANT**: When upgrading from 1.X.X versions
	of Barman to 2.X versions, users must explicitly add
	`archiver = on` (either globally or at server level).

	Created configuration templates for streaming and Ssh use cases

2016-08-24  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Enable streaming-only archiver with replication slots
	Remove the previous restriction that required standard WAL archiver
	(`archiver=on`) to be always present. Allow a server to operate
	with just WAL streaming if a replication slot is set (PostgreSQL
	9.4 or higher is required). Replication slots make sure that every
	WAL file is streamed to the Barman server.

	Basic checks have been implemented at configuration level, requiring
	`streaming_archiver=on` and a `slot_name` if `archiver=off`.

2016-08-25  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Improve replication slot error messages
	Barman didn't catch connection related exceptions in the
	`receive-wal` subcommand while creating and deleting a replication
	slot.

	This patch fixes that and reports to the user the connection error,
	avoiding to print a stack trace.

	This commit also adds a specific error message in case of drop of a
	replication slot that is currently in use.

2016-08-23  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Manage 'all replication slots are in use' error during slot creation
	Display an informative message to the user instead of a raw exception
	when the PostgreSQL's max_replication_slots setting is too low.

2016-08-23  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Improve replication slot related messages
	This patch improves the replicaiton slot creation and drop messages
	quoting the names of the servers and of the replication slots.

2016-08-23  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Fix error messages during create and drop of replication slots
	Modified error message emitted in case of an already existing
	replication slot during the execution of receive-wal --create-slot.  the
	message have been changed to error from info, replicating the behaviour
	of pg_receivexlog. Now, in case on error, the barman process exit code
	will be 1.

	The error message emitted during the execution of the receive-wal
	--drop-slot in case of a not existing replication slot have been changed
	to error as well.

2016-08-23  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Set version to 2.0 alpha 1
	Anticipating PostgreSQL's new versioning system kicking in
	from version 10.0, development team has decided to adopt the same
	policy to Barman's versioning system starting from version 2.0.

	The development team has also decided that this version deserves
	to be 2.0 due to the scope of the new features that will be introduced,
	in particular streaming-only backup and "zero data loss" backups.

2016-08-23  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Improve error messages for receive-wal subcommand
	Error messages for the receive-wal subcommands were incoherent and this
	patch improves them, using a common form.

	In addition to that, the availability of the 'slot_name' configuration
	parameter was checked before the server version, making that check
	useless if the PostgreSQL server version has no support for replication
	slots.

2016-08-20  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Support zero data loss backup (synchronous WAL streaming)
	Automatically start `pg_receivexlog` with `--synchronous`
	if the following conditions are met:

	- WAL streaming is active (see `streaming_archiver` and
	  `streaming_conninfo`)
	- the WAL streamer application name (see `streaming_archiver_name`)
	  is in the `synchronous_standby_names` priority list of the PostgreSQL
	  server (which defines the synchronous standby servers)
	- PostgreSQL server 9.4 or higher
	- pg_receivexlog 9.5 or higher

	This feature allows a Barman backup solution to act like a
	synchronous standby server in a PostgreSQL business continuity
	cluster, bringing RPO=0 backups (zero data loss).
	Currently, RPO=0 requires a replication slot to be properly configured
	(see `slot_name`).

2016-08-23  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Fix exception during `barman diagnose`
	Barman diagnose was trying to serialize a LooseVersion object to the
	JSON stream, which is not serializable by default.

	This patch add the support for (Loose|Strict)Version objects to the
	BarmanEncoder object treting them as a string.

2016-08-22  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Fix archiver by catching ENOENT exception
	Fixed a corner-case error that could occour when an unexpected
	file (e.g. .partial file) was not found anymore by the archiver
	process while trying to move it in the errors directory.

	This commit also makes logging messages easier to read.

	Add support for replication slots in `receive-wal` command
	If `slot_name` option is set and `streaming_archiver` is enabled, the
	`receive-wal` command will use the given replication slot to ensure
	that no WAL file is lost before its archival.

	The `check` command will monitor the status of the configured slot
	on the PostgreSQL side, accordingly with the value of the
	`streaming_archiver` option: if `streaming_archiver` is on, it will make
	sure that the slot exists and it is used, otherwise it will warn the
	user in case a stale slot is found.

	Fix directory permissions when backup_method=postgres
	This patch fixes how pg_basebackup manages the permissions of
	the destination directory of a backup on the barman server,
	forcing 0700 at creation time.
	The same rights are applied to the destination directory of every
	tablespace copied.

	Fix misleading message on pg_receivexlog termination
	In case of termination of the pg_receivexlog subprocess using a signal,
	a misleading entry was written in the log file.

	This patch improves the error message.

2016-08-13  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Introduce batch size for WAL archiving
	Previously, the `archive-wal` command would scan the
	incoming directories for both standard and streaming archiving
	and then process all the available WAL files in one single
	run.

	While this remains the default behaviour, two global/server
	options have been added to Barman: `archiver_batch_size` and
	`streaming_archiver_batch_size`.

	The first controls the batch size for the `archiver` process,
	the latter for the `streaming_archiver` process.
	The default value is 0, meaning unlimited batch (traditional
	behaviour in Barman). A value greater than 0 would trigger
	batch processing of WAL archiving in Barman, limiting a single
	run of `archive-wal` for the specific incoming queue (file archival
	or streaming) to that value.

	For example, setting `archiver_batch_size` to `10` would allow
	the `archive_wal` command to stop after processing a maximum of
	10 WAL segments from `archive_command` in the same run (assuming
	`archiver` is enabled). In those contexts where `streaming_archiver`
	is enabled, setting `streaming_archiver_batch_size` to `10` would
	reach the same goal for WAL segments that have been streamed to
	Barman.

	These settings should be tuned based on the server's workload
	and the frequency of the `barman cron`. A more distributed
	WAL processing certainly reduces the probability of xlog.db
	locking (be careful not to set these value too low - the risk
	is that your Barman server stays behind the server's WAL production).

	Renamed WalArchiverBatch class into a more appropriate WalArchiverQueue.

	Add to receive-wal the '--drop-slot' option
	This patch adds to the 'receive-wal' Barman subcommand a '--drop-slot'
	option. That option drop the replication slot named in the 'slot_name'
	configuration parameter.

	The patch also adds the relative documentation to the Barman man
	page in the section 1.

2016-07-30  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Add to receive-wal the '--create-slot' option
	This patch adds to the 'receive-wal' Barman subcommand a

2016-08-12  Leonardo Cecchi  <leonardo.cecchi@2ndQuadrant.it>

	Correctly handle history files from streaming
	Since 9.3, `pg_receivexlog` follows timeline switches and creates
	appropriate `.history` files when needed. Previous implementation
	in Barman of WAL archiving from streaming connections erroneously
	skipped history files and treated them as errors.
	This patch fixes this behaviour.

2016-08-04  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Avoid to lock XLOGDB while checking if WAL archiving is set up
	The patch avoid to take a lock during the checking of the WAL
	archiving setup.

	This is important for invocations of `barman check` to work correctly
	even when there are long activities on the XLOGDB file, i.e. when the
	archive process is managing many WAL files.

	Fix flake8 version for Unit Tests

2016-07-28  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Check tablespace-mapping option in pg_basebackup
	With `postgres` backup method, tablespaces are supported only
	for PostgreSQL servers 9.3 or higher and pg_basebackup 9.4 or higher.

	The reason is that pg_basebackup supports the `tablespace-mapping`
	option only from 9.4, and this option is needed in case there are
	tablespaces in the server. Given that pg_basebackup 9.4 is not
	compatible with PostgreSQL 9.1 and 9.2, these versions are not
	supported in case of tablespace presence.

	This patch adds a check for this scenario, providing users with
	warnings and preventing them from starting a backup in case
	the aforementioned requirements are not met.

	Documentation has been modified accordingly.

2016-07-19  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add the `slot_name` configuration parameter
	Setting the `slot_name` parameter on a server running at least
	PostgreSQL 9.4 will enable the usage of a physical replication slot
	to track the position of the `receive-wal` process.

	Cosmetic changes in barman-wal-restore.py help page

2016-07-14  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add a check for spurious messages in ssh_command output
	The aim of this check is to early detect potential communication
	problems through the configured ssh_command.

	For example, if the login script on the PostgreSQL server outputs
	any messages, this additional output could confuse Barman and
	therefore trigger random backup failures.

2016-07-13  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Fix replication-status command on PostgreSQL 9.1
	Barman was using the `pg_xlog_location_diff` function to calculate the
	difference in bytes between the master and the standby xlog locations.
	As `pg_xlog_location_diff` is available only from PostgreSQL 9.2, the
	`replication-status` command wasn't working on PostgreSQL 9.1.

	Adds the diff_lsn function to calculate the difference between
	two xlog locations.

	Fixes #45

	9.6 backup API support improvement
	PostgreSQL 9.6 provides functions to read the control file,
	so we can avoid parsing the backup_label to know the current
	timeline.

2016-06-16  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Support backup from standby
	This commit allows to backup standby servers using rsync or the new
	PostgreSQL 9.6 backup API.

	Allow invoking current_xlog_info on standby servers
	Previously, `pg_current_xlog_location` was used to get the current
	transaction log location, but this function can't be used on a standby
	server. Now the code checks the server type and use
	`pg_last_xlog_replay_location` if the server is in recovery mode.

	Uniform backup_label parsing
	The backup_label file was previouly parsed in multiple places of code.
	This code has been moved in a dedicated method.

2016-05-30  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Add support for concurrent backups with PostgreSQL 9.6
	As of version 9.6 PostgreSQL support concurrent backups natively.
	Add support to the new API, using new calls for concurrent
	backups. Users from PostgreSQL 9.2 to 9.5 can continue using
	the pgespresso extension.

	Code has been refactored accordingly.

	Refine the logic to detect unused WAL files.
	When multiple timelines are present in the archive, avoid purging
	WAL files that could be used by a backup on a different timeline.

2016-06-13  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Store detailed backup mode in backup.info file
	The `mode` field is present since long time, but before was always set
	to `default`.

	From now on, the `mode` field contains a descriptive string that shows
	the type of executor involved in the backup (rsync/postgres) and, if
	present, the strategy of the backup executor (exclusive/concurrent)

2016-06-03  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Add a warning message to show-backup checking timelines
	If after a backup there is a timeline switch, the "Last WAL" field from
	the show-backup subcommand will show the last available WAL on the
	timeline on which the backup was taken and not the last archived one.
	This behaviour, while it's correct, can confuse the user.

	Now barman handles such situation and emits a warning if there is more
	than one timeline reachable from the displayed backup.

	Base backups through PostgreSQL streaming replication
	Enable 'streamrep' only base backups with `backup_method=postgres`
	configuration option (global/server). Requires a valid streaming
	replication connection.

	Barman's implementation relies on `pg_basebackup`, therefore the
	following limitations apply:

	- `bandwidth_limit` is available with `pg_basebackup` >= 9.4 only
	- `network_compression`, `reuse_backup` and `tablespace_bandwidth_limit`
	  are not supported
	- configuration files outside PGDATA are not copied

2016-05-30  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add contrib/barman-wal-restore.py
	Python version of the WAL restore script to be used as
	'restore_command' for recovery or fallback method with standby
	servers. This script invokes 'barman get-wal' through
	a secure shell channel, and supports also parallel fetching
	of WAL files (requires Barman 1.6.1+).

	Requires argparse. Supersedes barman-wal-restore for bash.

2016-05-27  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Limit the maximum execution time of 'barman check' command
	Add a configurable timeout for the execution of the 'barman check'

	Refactor current_xlog_* properties in PostgreSQLConnection
	Introduce the current_xlog_info property that returns detailed info
	about current xlog location.

	Rename current_xlog property as current_xlog_file_name.

	Now current_xlog_file_name and current_xlog_location properties have
	been reimplemented and now they call current_xlog_info.

	Generalise DataTransferFailure exception
	A DataTransferFailure exception is not necessarily related to rsync only.
	Make it generic by accepting the command name as argument in the
	from_command_error factory method.

	Extract _purge_unused_wal_files method from SshBackupExecutor
	For reuse purposed, the code responsible for removing unused wal files
	in the backup method of SshBackupExecutor has been extracted.
	A new method called _purge_unused_wal_files is now part of the base class.

	The --target option allows users to limit the scope to
	only hot standby servers ('hot-standby') or WAL streaming
	clients, such as pg_receivexlog ('wal-streamer'). By default,
	--target is set to 'all'.

2016-05-05  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Check for 'backup_label' on the master
	If a PostgreSQL server is abruptly shut down when an
	exclusive backup is in progress, the 'backup_label' file
	will stay inside PGDATA.

	In case of a failed exclusive backup, if the Postgres server
	is down, "barman check" verifies that a backup_label is present.
	If so, prints "A 'backup_label' is present".

	Fixes #69

	compression (introduced in 1.6.0 development branch).

	Fixes: #27

	Remove trashing of old WAL files from the archiver
	The archiver now always archives any file with a valid name that
	finds inside the incoming directory.

	NOTE: The block of code that has been removed changes behaviour
	of existing Barman installations, but in a conservative way.
	We defer to future versions of Barman to better understand
	WAL files' sequentiality (parsing history files, for example),
	by writing specific classes/modules responsible for deeper
	and more robust checks in the archive area.

	Manage the termination of receive-wal in cron
	When the 'streaming_archive' option is disabled for a server,
	a cron execution makes sure that a running receive-wal process
	is correctly terminated.

	Clearer output and logging messages for `receive-wal`.

2016-02-05  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Add check for archiver errors
	Barman now checks for the presence of files in the error directory.

	Improve error handling when required server parameters are missing
	Add error handling in case a required parameter (i.e. ssh_command,
	conninfo, ...) is missing, by emitting meaningful error messages.

2016-02-02  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Adjust severity of some messages produced by cron command
	The messages about subprocess execution produced by the cron command
	were emitted for every cron run. They provide little information and
	their presence may make the log difficult to analyse, so they have been
	removed from log.

	Add 'receive-wal' cron integration
	Add integration of the new command 'receive-wal' during the execution of
	the cron command.

	If the option 'streaming_archiver' is on, the command 'receive-wal' is
	automatically executed as subprocess by the cron command, allowing
	Barman to receive WAL files from PostgreSQL using the native streaming
	protocol.

	TODO: Implement a way to interrupt a running streaming process

2015-12-09  Stefano Zacchiroli  <zack@upsilon.cc>

	Add support for the pigz compressor
	Pigz on-disk format is the same of gzip, but (de)compression is much
	faster due to the usage of CPU parallelism.

	For write-intense workloads pigz vs gzip might make the difference,
	between struggling to keep up with archiving incoming WALs and being
	able to keep up easily.

2016-01-09  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Add check() method in WalArchiver classes
	Move code from the server.check_postgres() method in
	the WalArchiver class, so that each implementation (FileWalArchiver
	and StreamingArchiver) perform their specific checks.
	Created the RemoteStatusMixin class that implements a cacheable
	version of remote status information.

	Currently it is only used by the WalArchiver class tree.
	TODO: propagate it to all other classes implementing the
	get_remote_status() function in a later commit.

2016-01-08  Christoph Moench-Tegeder  <christoph@2ndquadrant.de>

	Permit `archive_mode=always` for 9.5 servers
	PostgreSQL 9.5 introduces archive_mode=always. Even though Barman's
	current framework for checks does not allow yet to correctly monitor
	archiving from standby servers, Barman now allows users to set
	`archive_mode` to `always`, provided that archiving happens from the master.

	Rename get_first_backup and get_last_backup methods
	Renamed get_first_backup() and get_last_backup() methods of the
	Server and BackupManager classes, respectively into get_first_backup_id()
	and get_last_backup_id(), for coherence and code clarity.
	Now the fact that the method returns the ID of a backup instead
	of a BackupInfo object has been made explicit.

	Fix management of backup id during backup deletion
	Fix an error that prevents the deletion of an existing
	backup while a backup on the same server is in progress.

	Fixes #22

	Use isort python package to keep imports ordered

2015-12-14  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Implement `receive-wal` command
	The `receive-wal` command receives the stream of transaction logs for a
	server. The process relies on `pg_receivexlog` to receive WAL files from
	a PostgreSQL server through the streaming protocol.
	It is a foreground process which lasts until it receives a SIGINT.

2015-12-31  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add support for long running Commands
	The Command class now supports the execution of long running
	subprocesses, by passing the subprocess output and error streams
	to a handler, line by line.

	Remove spurious newlines from log lines
	Error messages coming from libpq often terminate with a newline.
	Always call strip() on strings that have been extracted from
	exceptions before logging them.

	Make get_remote_status methods behaviour coherent
	A 'get_remote_status' method should never raise an exception in case of
	error. The expected behaviour is to set missing values to None in the
	resulting dictionary.

2015-12-29  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Fix exception when streaming connection is unavailable
	Previously, when 'streaming_archiver' was on and pg_receivexlog correctly
	installed, Barman would raise an AttributeError exception when streaming
	connection to PostgreSQL was unavailable, as it could not detect the
	server version.

	This commit fixes the error by modifying the management of a failed
	connection to PostgreSQL through streaming connection. It also adds
	an unit test for this scenario, as well as hints for the user during
	`barman check` suggesting a possible streaming connection error.

2015-12-28  Leonardo Cecchi  <leonardo.cecchi@2ndquadrant.it>

	Propagate "-c" option to any Barman subprocess
	The "-c" option lets users specify a custom location for the configuration
	file. It must be propagated to every Barman subprocess for consistency
	of behaviour.

	Fixes #19

	Update documentation about WAL archiving

2015-12-22  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Manage WAL duplicates in `archive-wal` command
	In case a WAL file is archived twice, `archive-wal` will check
	if the new file is identical to the already archived one (compressed
	WAL files will be decompressed and checked). If yes, the second
	file is discarded, otherwise it is saved in the 'errors' directory.

	Accept compressed WAL files in incoming directory
	In case a WAL file in the incoming directory is already compressed
	using a known algorithm, archive it as is.

	Add streaming support to 'archive-wal' command
	The `archive-wal` command now looks for both archived WAL files
	(shipped from PostgreSQL through its `archive_command`) and streamed
	ones (via the `receive-wal` command).

2015-12-24  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Add sleep time option to `barman-wal-restore` script
	Introduce the '-s seconds' option to the barman-wal-restore script.
	After a failure of the get-wal command, the script will sleep for
	the specified amount of seconds (default 0, no wait) before
	exiting the restore_command from PostgreSQL.

	Closes #7

	Remove redundant sete[gu]id() calls
	Python's documentation of the os.setuid/os.setgid calls is
	oversimplified to the point of being wrong. Under the hood,
	the setuid(2)/setgid(2) functions are used, thus making these
	calls as POSIX compliant as the underlying operating system.
	As barman won't be installed SUID (it's an interpreter file),
	effective, real and saved user id should always be the same.
	That way, the only reason to use setuid() family calls at all
	is for a privileged user (root) to change over to the barman
	(unprivileged) user. According to POSIX.1-2013, the setuid()
	call changes all three (real, effective and saved) uids if
	called by a privileged user (the same holds for setgid() and
	the group ids). In this construct, the additional seti[gu]id
	calls are redundant no-ops and can be removed.

2015-11-27  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Add support for 'streaming_archiver' option
	Add a global/server boolean option called 'streaming_archiver' which
	enables the use of the PostgreSQL's streaming protocol to receive
	transaction logs from a server.
	If set to 'on', Barman expects to find `pg_receivexlog` in the PATH
	(see `path` option) and that streaming connection for the server is
	properly working. Subsequently, it activates both proper connection
	checks and management of WAL files.

	Refactored the code to use a new class, the StreamingWalArchiver,
	which is responsible for managing WAL files using a streaming
	connection.

	Add support for 'archiver' option
	Add a global/server boolean option called 'archiver' which
	enables continuous WAL archiving (through log shipping using
	PostgreSQL's archive_command) for a specific server.
	If set the 'true' (default), Barman expects that PostgreSQL
	continously deposits WAL files in the 'incoming' directory
	of that server, and subsequently activates proper checks and
	management.

	Refactored the code to use a new class, the FileWalArchiver.
	The class is in charge of both archival and compression of WAL files.
	This is the first step towards the implementation of streaming
	archiving support.

	Added the `streaming_conninfo` option to Barman configuration.
	This option (with server scope only), adds the support in Barman
	for a streaming replication connection to a PostgreSQL server.

	Added also a simple check for the barman check command, that tests
	that the streaming connection to PostgreSQL is properly working.

2015-11-13  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Add support for `path_prefix` configuration option
	The `path_prefix` global/server option can contain one
	or more absolute paths, separated by colon, where Barman
	looks for executable files.

	The paths specified in `path_prefix` are tried before the
	ones specified in `PATH` environment variable.

	By terminating a retry hook script with EXIT_ABORT_STOP, users
	request Barman to stop its main operation (i.e. backup or WAL archival).

	EXIT_ABORT_CONTINUE is implemented by every retry hook script.

	EXIT_ABORT_STOP is currently implemented only with 'pre_backup_retry_script'
	and 'pre_archive_retry_script'.

	EXIT_ABORT_STOP is currently ignored by 'post_backup_retry_script' and

	(include, include_if_exists, include_dir) are not supported

	During backup, warn users and list the files that require

	Workaround for rsync on SUSE Linux
	Many thanks to Christoph Moench-Tegeder <christoph@2ndquadrant.de>
	for his workaround proposal. This fixes the outstanding issue
	on SUSE Linux - previously raised by issues #13 and #26.
	See also: https://bugzilla.opensuse.org/show_bug.cgi?id=898513

2015-08-17  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Added copy_method option (fixed to rsync)

2015-08-06  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Support for 'retry' hook scripts for backup and WAL archiving
	A 'retry' hook script is a special kind of hook scripts that Barman
	tries to run indefinitely until it either returns a SUCCESS (0) or
	an ABORT (63) exit code.

	Safe hook scripts are executed immediately before (pre) and after (post)
	the command execution. Standard hook scripts are executed immediately
	before (pre) and after (post) the retry hook scripts.

	This patch adds support for pre/post retry hook scripts for backup
	and WAL archiving.

	The following four global/server configuration options have been added:

	* pre_backup_retry_script: executed before a backup
	* post_backup_retry_script: executed after a backup
	* pre_archive_retry_script: executed before a WAL archive operation
	* post_archive_retry_script: executed after a WAL archive operation

	By default, no retry hook script is executed. Environment variables
	are identical to the equivalent standard hook script.

2015-08-12  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Updated AUTHORS file

2014-05-29  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Support for the 'get-wal' command
	The 'barman get-wal' command allows users to fetch any WAL file
	from the archive of a specific server in Barman.

2015-08-21  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Add simple Travis CI integration

2015-07-30  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Preserve Timeline history files. Fixes #70.
	Added check for the management of history files during the removal of a
	backup or during normal maintenance operations (cron).

2015-08-06  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Forbid the delete of a running backup
	Block the execution of a barman delete command on a backup that is in progress.
	Use locks to ensure that there are no running backups on that server.
	Otherwise check for the position of the backup to be deleted in the
	catalogue and its status: if it is the first backup and its status is STARTED or EMPTY,
	the backup is running and delete is forbidden.

2015-08-03  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Follow symlinks when checking directory paths
	Check conflicting paths in configuration files using canonical paths and
	following symlinks when necessary.

2015-07-13  Francesco Canovai  <francesco.canovai@2ndquadrant.it>

	Pin mock==1.0.1 for testing.
	In version 1.1.x mock has changed some behaviours and is currently
	incompatible with our unit tests.

2015-07-08  Stefano Bianucci  <stefano.bianucci@2ndquadrant.it>

	Execute check() before starting a backup
	Execute the full suite of tests from barman check command before
	starting a backup. Skip the execution of a backup in case check
	fails.

	Add a strategy for managing the results of the checks. Now every
	check is properly logged as error (failure) or debug (success).

2015-07-03  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

2015-07-01  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Improved management of configuration in tests
	Improved and simplified the management of configurations in tests. Added
	a method for the creation of dictionaries containing all the keys that
	are usually present in a configuration. Updated tests accordingly.

2015-06-18  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Second part of the backup_executor module's refactor
	Refactored and streamlined the executor module. Introduced a specific
	class for physical backup with Rsync through Ssh, as well as a strategy
	pattern for the management of exclusive and concurrent backups (for
	backups from a standby).

2015-06-23  Gabriele Bartolini  <gabriele.bartolini@2ndquadrant.it>

	Standard error management for server commands
	Standardised the process of managing errors with server commands in
	barman/cli.py. By default, inactive servers are skipped (without error)
	as well as temporarily disabled servers (with error). No distinction is
	made between calling a command with one server as target or with a list
	of them (including 'all'). Exceptions are check (no server is skipped,
	errors are returned only for active servers), cron (no error is ever
	returned), list-server and diagnose (both managing active/disabled
	servers with no errors). Inactive servers are the ones with 'active'
	option set to False. Disabled servers are the ones with internal
	directory conflicts (e.g. WALs directory = base backup directory).

2015-06-23  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Asciidoc support for man pages and tutorial

	For better usability, warn users about setting a proper value
	for wal_level setting in PostgreSQL.

2015-05-14  Stefano Bianucci  <stefano.bianucci@2ndquadrant.it>

	Add check for conflicting paths in Barman's configuration
	Added controls for path-clash during the creation of Barman servers.
	If there are conflicting paths, Barman will disable those servers
	containing errors.
	If a potentially destructive command like "backup" is issued on a server
	containing conflicts, Barman exits with an error message.

2015-05-21  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Complete refactor of the 'recover' command
	The main 'recover' command has been completely refactored, through
	the creation of a separate module, called 'recovery_executor'.
	The RecoveryExecutor class now embodies both local and remote
	operations, laying the road for future improvements.

	This patch also fixes #68, by disabling dangerous settings in
	postgresql.auto.conf (available from PostgreSQL 9.4).

	Basic unit tests have been added.

2015-05-19  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Rename class Server to ServerConfig in barman.config module
	Previously both barman.config and barman.server modules had a Server
	class. The former has now been renamed to ServerConfig, hence removing
	the ambiguity.

2015-03-24  Giulio Calacoci  <giulio.calacoci@2ndquadrant.com>

	Improved cache management of backups
	Streamlined the management of the cache of the backups.
	It is now possible to register and remove a backup from the cache.
	The cache structure has been simplified and now it is a simple
	dictionary of backups. Status filters are applied by the
	get_available_backups() method.
	Managed registration and removal of a backup in the cache
	during backup operations.

2015-03-02  Giulio Calacoci  <giulio.calacoci@2ndquadrant.com>

	Create backup_executor module and refactor backup.
	Extract all the methods relative to the execution of a backup into a
	dedicated object.
	The RsyncBackupExecutor encapsulates the operation of backing up a
	remote server using rsync and ssh to copy files.

2015-03-27  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Improved management of xlogb file
	The xlogdb file is now correctly fsynced when updated.
	Also, the rebuild-xlogdb command now operates on a temporary
	new file, which overwrites the main one when finished.

2015-03-27  Stefano Bianucci  <stefano.bianucci@2ndquadrant.it>

	Add "active" configuration option for a server
	It is now possible to temporarily disable a server through
	the 'active' configuration option. Defined at server level
	as a boolean, when set to False the server is ignored by
	main operational commands such as cron, backup and recover.
	By default, it is set to True.

2015-03-20  Giulio Calacoci  <giulio.calacoci@2ndquadrant.com>

	the correct names.

2015-03-17  Giulio Calacoci  <giulio.calacoci@2ndquadrant.com>

	Fix computation of WAL production ratio
	The WAL file ratio reported in the 'show-backup' command output was wrong
	because it was considering only the number of WALS produced during the
	backup instead of the number of WALs produced until next backup.

2015-02-25  Giulio Calacoci  <giulio.calacoci@2ndquadrant.com>

	Fix for WAL archival stop working if first backup is EMPTY
	In some rare cases, if an empty backup has left by a failure during a
	backup, the cron could start trashing WAL files, as if there is no
	available backups.

	Closes: #64

2015-03-06  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Added 'barman_lock_directory' global option
	Barman now allows to specify the default directory for locks through
	the global option called 'barman_lock_directory', by default set to
	'barman_home'. Lock files will be created inside this directory.

	Names of lock files have been slightly changed. However, this won't
	affect users of Barman, unless you are relying on their locations and
	paths.

	This patch introduces four classes for managing lock files:
	GlobalCronLock, ServerBackupLock, ServerCronLock and ServerXLOGDBLock.

2015-02-03  Giulio Calacoci  <giulio.calacoci@2ndquadrant.com>

	New backup directory structure
	Inside the backup directory the 'pgdata' has been renamed to 'data'.
	Tablespaces, if present, are stored into individual directories alongside
	the 'data' directory.
	During backup and recovery operations, tablespaces are copied individually
	using a separate rsync command.

	Store deduplication effects for incremental backup
	When incremental backup is enabled and uses hard links
	(reuse_backup = link), output of 'backup' command reports
	the effects of deduplication. The metrict is stored along
	the backup.info file in the 'deduplicated_size' field.

	IMPORTANT: this metric refers to the increment in size
	of the current backup from the previous backup and reflects
	only the situation at backup time.

2011-12-07  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Incremental base backup implementation
	Add support for reuse_backup global/server option, accepting
	three possible values:

	* off:  no incremental backup support (default)
	* copy: uses the last available backup as source (preventing unmodified
	        files from being copied)
	* link: same as copy but uses hard links on destination, if the filesystem
	        on the backup server allows it (reducing the occupied space)

	Add support for command line '--reuse-backup' option (default: link).

	Invoke WAL maintenance after a successful backup
	* At the end of the 'barman backup' command, maintenance operations
	  are automatically started for successful backups (equivalent to
	  manually executing a 'barman cron' command, just for that server)

	* Trashing of unuseful WALs (part of 'barman cron') has been changed
	  as follows:

	  * in case of one or more backups, delete WAL files older than
	    the start WAL of the first backup
	  * otherwise, trash WAL files in case of exclusive backup server
	    (that is, not concurrent)

2014-09-03  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Minor changes:
	 - In retry_backup_copy log the exception which caused the failure

	Support for 'last_backup_max_age'
	This new global/server option allows administrators
	to set the max age of the last backup, making it easier
	to detect any issues with periodical backup execution.

2014-06-18  Marco Nenciarini  <marco.nenciarini@2ndquadrant.it>

	Support for "smart" incremental recovery
	Avoid invoking rsync with --checksum option during recovery,
	while maintaining the same level of safety by splitting the
	copy operation in multiple steps.
	Barman will only use the --checksum option on files having identical
	time and size that have been modified after the start of the backup.
	This change greatly improves the speed of "incremental" recovery.

	Minor changes:
	- disable --checksum even for backup. During a backup the rsync
	  destination directory is empty, so it is safe to go with a plain
	  rsync
	- Put a ".barman-recover.info" with backup metadata inside the
	  destination directory during recover.

	Use Postgres' server time for both begin_time and end_time
	Minor changes:
	- make sure exceptions during backup are logged with stacktraces
	- commit on disk the backup status just after issuing the PostgreSQL
	  start_backup command

	Change version to 1.3.3-alpha.1

2014-06-09  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

2014-05-08  Giulio Calacoci  <giulio.calacoci@2ndquadrant.it>

	Retry option for base backup
	If a network error happens during rsync, add the ability
	to retry a defined number of time.

	Two options have been added:
	 * basebackup_retry_times: INT (> 0, default 1)
	     maximum number or retry before giving up
	 * basebackup_retry_sleep: INT (> 0, default 10)
	     wait time (seconds) before retrying, after an error

	27: Addresses potential corruption of WAL xlog.db files.
	In barman.lockfile.release() the file is unlinked (deleted). This effectively
	nullifies any future attempts to lock the file by a blocking process by deleting
	the open file table entry upon which the flock is based.

	This commit removes the unlink and instead unlocks the file and then closes the file
	descriptor leaving the lock file and open file table entry intact.

2012-12-08  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Add retention status to show-backup and list-backup commands

	Auto-management of retention policies for base backups
	Using the report() method for retention policies, enforce retention
	policy through cron (if policy mode is 'auto'), by deleting OBSOLETE
	backups.

	Retention status and report() method for retention policies
	Created the following states for retention policies:
	VALID, OBSOLETE, NONE and POTENTIALLY_OBSOLETE (an
	object which is OBSOLETE but cannot be removed
	automatically due to minimum_redundancy requirements).
	Created the report() method for the retention policy
	base class, which exected the _backup_report() method
	for base backups and the _wal_report() method for WAL
	retention policies (currently not enforced).
	The report method iterates through the DONE backups
	and according to the retention policy, classifies
	the backup. RedundancyRetentionPolicy uses the number
	of backups, RecoveryWindowRetentionPolicy uses the
	time window and the recoverability point concept.

	Integrated minimum_redundancy with "barman check"

	Initialisation of retention policies for a server
	Added the _init_retention_policies() method in the
	Server class constructor, which integrates with
	the new RetentionPolicy classes and performs
	syntax checking.
	Integrated retention policies with log, 'barman check'
	and 'barman status'.

	String representation conforms to retention syntax
	The string representation produces now a syntax-valid
	retention policy configuration string.
	The previous __str__ method has been renamed into debug()
	SimpleWALRetentionPolicy objects are now created from
	the server's main retention policy by the factory class.

2012-12-07  Gabriele Bartolini  <gabriele.bartolini@2ndQuadrant.it>

	Add the global/server option minimum_redundancy. Check it is >= 0. Guarantees that when delete is performed (or retention policies are enforced), this is the minimum number of backups to be kept for that server.

	Add support for retention_policy_mode global/server option which defines the method for enforcing retention policies (currently only "auto", in future versions "manual" will be allowed)

	Added first stub of retention policy classes

	Started version 1.2.0

	Add pre/post backup hook scripts definition (Closes: #7)
	Add the possibility to manage hook scripts before and after a base
	backup. Add the global (overridden per server) configuration options
	called:

	* pre_backup_script: executed before a backup
	* post_backup_script: executed after a backup

	Use the environment to pass at least the following variabiles:

	* BARMAN_BACKUP_DIR: backup destination directory
	* BARMAN_BACKUP_ID: ID of the backup
	* BARMAN_CONFIGURATION: configuration file used by barman
	* BARMAN_PHASE: 'pre' or 'post'
	* BARMAN_SERVER: name of the server

	The script definition is passed to the shell and can return any exit code.

	Barman won't perform any exit code check. It will simply log the result in the log file.

	To test it you can try adding

	pre_backup_script = env | grep ^BARMAN
	post_backup_script = env | grep ^BARMAN

	in your barman config and you'll see the variables on console.
