8e3464da80 v1.12: Page Checksums, Configuration, and Bug Fixes
IMPORTANT NOTE: In prior releases it was possible to specify options on the command-line that were invalid for the current command without getting an error. An error will now be generated for invalid options so it is important to carefully check command-line options in your environment to prevent disruption.

Bug Fixes:

* Fixed an issue where options that were invalid for the specified command could be provided on the command-line without generating an error. The options were ignored and did not cause any change in behavior, but it did lead to some confusion. Invalid options will now generate an error. (Reported by Nikhilchandra Kulkarni.)
* Fixed an issue where internal symlinks were not being created for tablespaces in the repository. This issue was only apparent when trying to bring up clusters in-place manually using filesystem snapshots and did not affect normal backup and restore.
* Fixed an issue that prevented errors from being output to the console before the logging system was initialized, i.e. while parsing options. Error codes were still being returned accurately so this would not have made a process look like it succeeded when it did not. (Reported by Adrian Vondendriesch.)
* Fixed an issue where the db-port option specified on the backup server would not be properly passed to the remote unless it was from the first configured database. (Reported by Michael Vitale.)

Features:

* Added the --checksum-page option to allow pgBackRest to validate page checksums in data files when checksums are enabled on PostgreSQL >= 9.3. Note that this functionality requires a C library which may not initially be available in OS packages. The option will automatically be enabled when the library is present and checksums are enabled on the cluster. (Suggested by Stephen Frost.)
* Added the --repo-link option to allow internal symlinks to be suppressed when the repository is located on a filesystem that does not support symlinks. This does not affect any pgBackRest functionality, but the convenience link latest will not be created and neither will internal tablespace symlinks, which will affect the ability to bring up clusters in-place manually using filesystem snapshots.
* Added the --repo-sync option to allow directory syncs in the repository to be disabled for file systems that do not support them, e.g. NTFS.
* Added a predictable log entry to signal that a command has completed successfully. For example a backup ends successfully with: INFO: backup command end: completed successfully. (Suggested by Jens Wilke.)

Refactoring:

* Abstracted code to determine which database cluster is the master and which are standbys. (Contributed by Cynthia Shang.)
* Improved consistency and flexibility of the protocol layer by using JSON for all messages.
* File copy protocol now accepts a function that can do additional processing on the copy buffers and return a result to the calling process.
* Improved IO->bufferRead to always return requested number of bytes until EOF.
* For simplicity, the pg_control file is now copied with the rest of the files instead of by itself of at the end of the process. The backup command does not require this behavior and the restore copies to a temporary file which is renamed at the end of the restore.
* Simplified the result hash of File->manifest(), Db->tablespaceMapGet(), and Db->databaseMapGet().
* Improved errors returned from child processes by removing redundant error level and code.
* Code cleanup in preparation for improved stanza-create command. (Contributed by Cynthia Shang.)
* Improved parameter/result logging in debug/trace functions.

1e0ca3056a v1.09: 9.6 Support, Configurability, and Bug Fixes
Bug Fixes:

* Fixed the check command to prevent an error message from being logged if the backup directory does not exist. (Fixed by Cynthia Shang.)
* Fixed error message to properly display the archive command when an invalid archive command is detected. (Reported by Jason O'Donnell.)
* Fixed an issue where the async archiver would not be started if archive-push did not have enough space to queue a new WAL segment. This meant that the queue would never be cleared without manual intervention (such as calling archive-push directly). PostgreSQL now receives errors when there is not enough space to store new WAL segments but the async process will still be started so that space is eventually freed. (Reported by Jens Wilke.)
* Fixed a remote timeout that occurred when a local process generated checksums (during resume or restore) but did not copy files, allowing the remote to go idle. (Reported by Jens Wilke.)

Features:

* Non-exclusive backups will automatically be used on PostgreSQL 9.6.
* Added the cmd-ssh option to allow the ssh client to be specified. (Suggested by Jens Wilke.)
* Added the log-level-stderr option to control whether console log messages are sent to stderr or stdout. By default this is set to warn which represents a change in behavior from previous versions, even though it may be more intuitive. Setting log-level-stderr=off will preserve the old behavior. (Suggested by Sascha Biberhofer.)
* Set application_name to "pgBackRest [command]" for database connections. (Suggested by Jens Wilke.)
* Check that archive_mode is enabled when archive-check option enabled.

Refactoring:

* Clarified error message when unable to acquire pgBackRest advisory lock to make it clear that it is not a PostgreSQL backup lock. (Suggested by Jens Wilke.)
* pgBackRest version number included in command start INFO log output.
* Process ID logged for local process start/stop INFO log output.

a8590c9ade v1.07: Thread to Process Conversion and Bug Fixes
Bug Fixes:

* Fixed an issue where tablespaces were copied from the master during standby backup.
* Fixed the check command so backup info is checked remotely and not just locally. (Fixed by Cynthia Shang.)
* Fixed an issue where retention-archive was not automatically being set when retention-archive-type=diff, resulting in a less aggressive than intended expiration of archive. (Fixed by Cynthia Shang.)

Features:

* Converted Perl threads to processes to improve compatibility and performance.
* Exclude contents of $PGDATA/pg_replslot directory so that replication slots on the master do not become part of the backup.
* The archive-start and archive-stop settings are now filled in backup.manifest even when archive-check=n.
* Additional warnings when archive retention settings may not have the intended effect or would allow indefinite retention. (Contributed by Cynthia Shang.)
* Experimental support for non-exclusive backups in PostgreSQL 9.6 rc1. Changes to the control/catalog/WAL versions in subsequent release candidates may break compatibility but pgBackRest will be updated with each release to keep pace.

Refactoring:

* Refactor of protocol minions in preparation for the new local minion.
* Remove obsolete thread index variable from File() module.
* Changed temporary file names to consistently use the .pgbackrest.tmp extension even if the destination file is compressed or has an appended checksum.
* Improve ASSERT error handling, safely check eval blocks, and convert $@ to $EVAL_ERROR.

be77136eae v1.06: Backup from Standby and Bug Fixes
Bug Fixes:

* Fixed an issue where a tablespace link that referenced another link would not produce an error, but instead skip the tablespace entirely. (Reported by Michael Vitale.)
* Fixed an issue where options that should not allow multiple values could be specified multiple times in pgbackrest.conf without an error being raised. (Reported by Michael Vitale.)
* Fixed an issue where the protocol-timeout option was not automatically increased when the db-timeout option was increased. (Reported by Todd Vernick.)

Features:

* Backup from a standby cluster. A connection to the primary cluster is still required to start/stop the backup and copy files that are not replicated, but the vast majority of files are copied from the standby in order to reduce load on the master.
* More flexible configuration for databases. Master and standby can both be configured on the backup server and pgBackRest will automatically determine which is the master. This means no configuration changes for backup are required after failing over from a master to standby when a separate backup server is used.
* Exclude directories during backup that are cleaned, recreated, or zeroed by PostgreSQL at startup. These include pgsql_tmp and pg_stat_tmp. The postgresql.auto.conf.tmp file is now excluded in addition to files that were already excluded: backup_label.old, postmaster.opts, postmaster.pid, recovery.conf, recovery.done.
* Experimental support for non-exclusive backups in PostgreSQL 9.6 beta4. Changes to the control/catalog/WAL versions in subsequent betas may break compatibility but pgBackRest will be updated with each release to keep pace.

Refactoring:

* Simplify protocol creation and identifying which host is local/remote.
* Removed all OP_* function constants that were used only for debugging, not in the protocol, and replaced with __PACKAGE__.
* Improvements in Db module: separated out connect() function, allow executeSql() calls that do not return data, and improve error handling.
* Improve error message for links that reference links in manifest build.
* Added hints to error message when relative paths are detected in archive-push or archive-get.
* Improve backup log messages to indicate which host the files are being copied from.

* Fixed an issue where db-path was not required for the check command so an assert was raised when it was missing rather than a polite error message. (Reported by Michael Vitale.)
* Fixed check command to throw an error when database version/id does not match that of the archive. (Fixed by Cynthia Shang.)
* Fixed an issue where a remote could try to start its own remote when the backup-host option was not present in pgbackrest.conf on the database server. (Reported by Lardière Sébastien.)
* Fixed an issue where the contents of pg_xlog were being backed up if the directory was symlinked. This didn't cause any issues during restore but was a waste of space.
* Fixed an invalid log() call in lock routines.

Features:

* Experimental support for non-exclusive backups in PostgreSQL 9.6 beta3. Changes to the control/catalog/WAL versions in subsequent betas may break compatibility but pgBackRest will be updated with each release to keep pace.

Refactoring:

* Enhancements to the protocol layer for improved reliability and error handling.
* All remote types now take locks. The exceptions date to when the test harness and pgBackRest were running in the same VM and no longer apply.
* Exceptions are now passed back from threads as messages when possible rather than raised directly.
* Temp files created during backup are now placed in the same directory as the target file.
* Output lock file name when a lock cannot be acquired to aid in debugging.
* Reduce calls to protocolGet() in backup/restore.
* Suppress banners on SSH protocol connections.
* Improved remote error messages to identify the host where the error was raised.

f2b3dda647 Fixed an issue where a remote could try to start its own remote.
This is a better approach than 93320b8 (reverted in this commit) because it ensures that the remote type will be none so any functions that utilize optionRemoteTypeTest will work correctly.

This bug was only an issue when backup-host was not properly configured on the database host.

1b62354dcb v1.03: Check Command and Bug Fixes
Bug Fixes:

* Fixed an issue where keep-alives could be starved out by lots of small files during multi-threaded backup. They were also completely absent from single/multi-threaded backup resume and restore checksumming. (Reported by Janice Parkinson, Chris Barber.)
* Fixed an issue where the expire command would refuse to run when explicitly called from the command line if the db-host option was set. This was not an issue when expire was run automatically after a backup (Reported by Chris Barber.)
* Fixed an issue where validation was being running on archive_command even when the archive-check option was disabled.

Features:

* Added check command to validate that pgBackRest is configured correctly for archiving and backups. (Contributed by Cynthia Shang.)
* Added the protocol-timeout option. Previously protocol-timeout was set as db-timeout + 30 seconds.
* Failure to shutdown remotes at the end of the backup no longer throws an exception. Instead a warning is generated that recommends a higher protocol-timeout.
* Experimental support for non-exclusive backups in PostgreSQL 9.6 beta2. Changes to the control/catalog/WAL versions in subsequent betas may break compatibility but pgBackRest will be updated with each release to keep pace.

Refactoring:

* The pg_xlogfile_name() function is no longer used to construct WAL filenames from LSNs. While this function is convenient it is not available on a standby. Instead, the archive is searched for the LSN in order to find the timeline. If due to some misadventure the LSN appears on multiple timelines then an error will be thrown, whereas before this condition would have passed unnoticed.
* Option handling is now far more strict. Previously it was possible for a command to use an option that was not explicitly assigned to it. This was especially true for the backup-host and db-host options which are used to determine locality.
* Improved handling of users/groups captured during backup that do not exist on the restore host. Also explicitly handle the case where user/group is not mapped to a name.
* Changed version variable to a constant. It had originally been designed to play nice with a specific packaging tool but that tool was never used.

9ab0dd80f7 v1.00: New Repository Format and Configuration Scheme, Link Support
* This flag day release breaks compatibility with older versions of pgBackRest. The manifest format, on-disk structure, configuration scheme, and the exe/path names have all changed. You must create a new repository to hold backups for this version of pgBackRest and keep your older repository for a time in case you need to do a restore. Restores from the prior repository will require the prior version of pgBackRest but because of name changes it is possible to have 1.00 and a prior version of pgBackRest installed at the same time. See the notes below for more detailed information on what has changed.

* Implemented a new configuration scheme which should be far simpler to use. See the User Guide and Configuration Reference for details but for a simple configuration all options can now be placed in the stanza section. Options that are shared between stanzas can be placed in the [global] section. More complex configurations can still make use of command sections though this should be a rare use case.

* The repo-path option now always refers to the repository where backups and archive are stored, whether local or remote, so the repo-remote-path option has been removed. The new spool-path option can be used to define a location for queueing WAL segments when archiving asynchronously. A local repository is no longer required.

* The default configuration filename is now pgbackrest.conf instead of pg_backrest.conf. This was done for consistency with other naming changes but also to prevent old config files from being loaded accidentally when migrating to 1.00.

* The default repository name was changed from /var/lib/backup to /var/lib/pgbackrest.

* Lock files are now stored in /tmp/pgbackrest by default. These days /run/pgbackrest is the preferred location but that would require init scripts which are not part of this release. The lock-path option can be used to configure the lock directory.

* Log files are now stored in /var/log/pgbackrest by default and no longer have the date appended so they can be managed with logrotate. The log-path option can be used to configure the lock directory.

* Executable filename changed from pg_backrest to pgbackrest.

* All files and directories linked from PGDATA are now included in the backup. By default links will be restored directly into PGDATA as files or directories. The --link-all option can be used to restore all links to their original locations. The --link-map option can be used to remap a link to a new location.

* Removed --tablespace option and replaced with --tablespace-map-all option which should more clearly indicate its function.

* Added detail log level which will output more information than info without being as verbose as debug.

aea14c8553 v0.91: Tablespace Bug Fix and Minor Enhancements
* **IMPORTANT BUG FIX FOR TABLESPACES**: A change to the repository format was accidentally introduced in 0.90 which means the on-disk backup was no longer a valid PostgreSQL cluster when the backup contained tablespaces. This only affected users who directly copied the backups to restore PostgreSQL clusters rather than using the restore command. However, the fix breaks compatibility with older backups that contain tablespaces no matter how they are being restored (pgBackRest will throw errors and refuse to restore). New full backups should be taken immediately after installing version 0.91 for any clusters that contain tablespaces. If older backups need to be restored then use a version of pgBackRest that matches the backup version. _Reported by Evan Benoit_.

* Copy global/pg_control last during backups.

* Write .info and .manifest files to temp before moving them to their final locations and fsync'ing.

* Rename --no-start-stop option to --no-online.

* Static source analysis using Perl-Critic, currently passes on gentle.

631535ae4f v0.90: 9.5 Support, Various Enhancements, and Minor Bug Fixes
* Fixed an issue where specifying --no-archive-check would throw a configuration error. Reported by Jason O'Donnell.

* Fixed an issue where a temp WAL file left over after a well-timed system crash could cause the next archive-push to fail.

* Fixed an issue where document generation failed because some OSs are not tolerant of having multiple installed versions of PostgreSQL. A separate VM is now created for each version. Also added a sleep after database starts during document generation to ensure the database is running before the next command runs. Reported by John Harvey.

* The retention-archive option can now be be safely set to less than backup retention (retention-full or retention-diff) without also specifying archive-copy=n. The WAL required to make the backups that fall outside of archive retention consistent will be preserved in the archive. However, in this case PITR will not be possible for the backups that fall outside of archive retention.

* When backing up and restoring tablespaces pgBackRest only operates on the subdirectory created for the version of PostgreSQL being run against. Since multiple versions can live in a tablespace (especially during a binary upgrade) this prevents too many files from being copied during a backup and other versions possibly being wiped out during a restore. This only applies to PostgreSQL >= 9.0 -- prior versions of PostgreSQL could not share a tablespace directory.

* Generate an error when archive-check=y but archivecommand does not execute pgbackrest. Contributed by Jason O'Donnell.

* Improved error message when repo-path or repo-remote-path does not exist.

* Added checks for --delta and --force restore options to ensure that the destination is a valid $PGDATA directory. pgBackRest will check for the presence of PGVERSION or backup.manifest (left over from an aborted restore). If neither file is found then --delta and --force will be disabled but the restore will proceed unless there are files in the $PGDATA directory (or any tablespace directories) in which case the operation will be aborted.

* When restore --set=latest (the default) the actual backup restored will be output to the log.

* Support for PostgreSQL 9.5 partial WAL segments and recoverytargetaction setting. The archivemode = 'always' setting is not yet supported.

* Support for recoverytarget = 'immediate' recovery setting introduced in PostgreSQL 9.4.

* The following tablespace checks have been added: paths or files in pgtblspc, relative links in pgtblspc, tablespaces in $PGDATA. All three will generate errors.

50a62fab6d v0.89: Timeout Bug Fix and Restore Read-Only Repositories
* Fixed an issue where longer-running backups/restores would timeout when remote and threaded. Keepalives are now used to make sure the remote for the main process does not timeout while the thread remotes do all the work. The error message for timeouts was also improved to make debugging easier.

* Allow restores to be performed on a read-only repository by using --no-lock and --log-level-file=off. The --no-lock option can only be used with restores.

* Minor styling changes, clarifications and rewording in the user guide.

* The dev branch has been renamed to master and for the time being the master branch has renamed to release, though it will probably be removed at some point -- thus ends the gitflow experiment for pgBackRest. It is recommended that any forks get re-forked and clones get re-cloned.

097eb7ca41 v0.85: Start/Stop Commands and Minor Bug Fixes
* Added new feature to allow all pgBackRest operations to be stopped or started using the stop and start commands.  This prevents any pgBackRest processes from running on a system where PostgreSQL is shutdown or the system needs to be quiesced for some reason.

* Removed dependency on IO::String module.

* Fixed an issue where an error could be returned after a backup or restore completely successfully.

* Fixed an issue where a resume would fail if temp files were left in the root backup directory when the backup failed.  This scenario was likely if the backup process got terminated during the copy phase.

* Experimental support for PostgreSQL 9.5 beta1.  This may break when the control version or WAL magic changes in future versions but will be updated in each pgBackRest release to keep pace.  All regression tests pass except for --target-resume tests (this functionality has changed in 9.5) and there is no testing yet for .partial WAL segments.

9be15d00f8 v0.82: Refactoring, Command-line Help, and Minor Bug Fixes
* Fixed an issue where resumed compressed backups were not preserving existing files.

* Fixed an issue where resume and incr/diff would not ensure that the prior backup had the same compression and hardlink settings.

* Fixed an issue where a cold backup using --no-start-stop could be started on a running PostgreSQL cluster without --force specified.

* Fixed an issue where a thread could be started even when none were requested.

* Fixed an issue where the pgBackRest version number was not being updated in backup.info and archive.info after an upgrade/downgrade.

* Fixed an issue where the info command was throwing an exception when the repository contained no stanzas.  Reported by Stephen Frost.

* Fixed an issue where the PostgreSQL pg_stop_backup() NOTICEs were being output to stderr.  Reported by Stephen Frost.

* Renamed recovery-setting option and section to recovery-option to be more consistent with pgBackRest naming conventions.

* Command-line help is now extracted from the same XML source that is used for the other documentation and includes much more detail.

* Code cleanup and refactoring to standardize on patterns that have evolved over time.

* Added dynamic module loading to speed up commands, especially asynchronous archiving.

* Expiration tests are now synthetic rather than based on actual backups.  This will allow development of more advanced expiration features.

* Experimental support for PostgreSQL 9.5 alpha2.  This may break when the control version or WAL magic changes in future versions but will be updated in each pgBackRest release to keep pace.  All regression tests pass except for --target-resume tests (this functionality has changed in 9.5) and there is no testing yet for .partial WAL segments.

a59284a4cc v0.80: DBI Support, Stability, and Convenience Features
* Fixed an issue that caused the formatted timestamp for both the oldest and newest backups to be reported as the current time by the info command.  Only text output was affected -- json output reported the correct epoch values.  Reported by Michael Renner.

* Fixed protocol issue that was preventing ssh errors (especially on connection) from being logged.

* Now using Perl DBI and DBD::Pg for connections to PostgreSQL rather than psql.  The cmd-psql and cmd-psql-option settings have been removed and replaced with db-port and db-socket-path.

* Add stop-auto option to allow failed backups to automatically be stopped when a new backup starts.

* Add db-timeout option to limit the amount of time pgBackRest will wait for pg_start_backup() and pg_stop_backup() to return.

* Remove pg_control file at the beginning of the restore and copy it back at the very end.  This prevents the possibility that a partial restore can be started by PostgreSQL.

* The repository is now created and updated with consistent directory and file modes.  By default umask is set to 0000 but this can be disabled with the neutral-umask setting.

* Added checks to be sure the db-path setting is consistent with db-port by comparing the data_directory as reported by the cluster against the db-path setting and the version as reported by the cluster against the value read from pg_control.  The db-socket-path setting is checked to be sure it is an absolute path.

* Experimental support for PostgreSQL 9.5 alpha1.  This may break when the control version or WAL magic changes in future versions but will be updated in each pgBackRest release to keep pace.  All regression tests pass except for --target-resume tests (this functionality has changed in 9.5) and there is no testing yet for .partial WAL segments.

* Major refactoring of the protocol layer to support future development.

* Added vagrant test configurations for Ubuntu 14.04 and CentOS 7.

* Split most of README.md out into USERGUIDE.md and CHANGELOG.md because it was becoming unwieldy.  Changed most references to "database" in the user guide to "database cluster" for clarity.

Most tests are working now.  What's not working:

2) No tests for the new .partial WAL segments that can be generated on timeline switch.
