495dec44f0 v2.24: Auto-Select Backup Set for Time Target
Bug Fixes:

* Prevent defunct processes in asynchronous archive commands. (Reviewed by Stephen Frost. Reported by Adam Brusselback, ejberdecia.)
* Error when archive-get/archive-push/restore are not run on a PostgreSQL host. (Reviewed by Stephen Frost. Reported by Jesper St John.)
* Read HTTP content to eof when size/encoding not specified. (Reviewed by Cynthia Shang. Reported by Christian ROUX.)
* Fix resume when the resumable backup was created by Perl. In this case the resumable backup should be ignored, but the C code was not able to load the partial manifest written by Perl since the format differs slightly. Add validations to catch this case and continue gracefully. (Reported by Kacey Holston.)

Features:

* Auto-select backup set on restore when time target is specified. Auto-selection is performed only when --set is not specified. If a backup set for the given target time cannot not be found, the latest (default) backup set will be used. (Contributed by Cynthia Shang.)

Improvements:

* Skip pg_internal.init temp file during backup. (Reviewed by Cynthia Shang. Suggested by Michael Paquier.)
* Add more validations to the manifest on backup. (Reviewed by Cynthia Shang.)

Documentation Improvements:

* Prevent lock-bot from adding comments to locked issues. (Suggested by Christoph Berg.)

2358d34485 v2.23: Bug Fix
Bug Fixes:

* Fix missing files corrupting the manifest. If a file was removed by PostgreSQL during the backup (or was missing from the standby) then the next file might not be copied and updated in the manifest. If this happened then the backup would error when restored. (Reviewed by Cynthia Shang. Reported by Vitaliy Kukharik.)

Improvements:

* Use pkg-config instead of xml2-config for libxml2 build options. (Contributed by David Steele, Adrian Vondendriesch.)
* Validate checksums are set in the manifest on backup/restore. (Reviewed by Cynthia Shang.)

bae6e1c9e3 v2.22: Bug Fix
Bug Fixes:

* Fix error in timeline conversion. The timeline is required to verify WAL segments in the archive after a backup. The conversion was performed base 10 instead of 16, which led to errors when the timeline was ≥ 0xA. (Reported by Lukas Ertl, Eric Veldhuyzen.)

2c0ba0820d v2.21: C Migration Complete
Bug Fixes:

* Fix options being ignored by asynchronous commands. The asynchronous archive-get/archive-push processes were not loading options configured in command configuration sections, e.g. [global:archive-get]. (Reviewed by Cynthia Shang. Reported by Urs Kramer.)
* Fix handling of \ in filenames. \ was not being properly escaped when calculating the manifest checksum which prevented the manifest from loading. Since instances of \ in cluster filenames should be rare to nonexistent this does not seem likely to be a serious problem in the field.

Features:

* pgBackRest is now pure C.
* Add pg-user option. Specifies the database user name when connecting to PostgreSQL. If not specified pgBackRest will connect with the local OS user or PGUSER, which was the previous behavior. (Contributed by Mike Palmiotto.)
* Allow path-style URIs in S3 driver.

Improvements:

* The backup command is implemented entirely in C. (Reviewed by Cynthia Shang.)

39fc2b7ad6 v2.20: Bug Fixes
Bug Fixes:

* Fix archive-push/archive-get when PGDATA is symlinked. These commands tried to use cwd() as PGDATA but this would disagree with the path configured in pgBackRest if PGDATA was symlinked. If cwd() does not match the pgBackRest path then chdir() to the path and make sure the next cwd() matches the result from the first call. (Reported by Stephen Frost, Milosz Suchy.)
* Fix reference list when backup.info is reconstructed in expire command. Since the backup command is still using the Perl version of reconstruct this issue will not express unless 1) there is a backup missing from backup.info and 2) the expire command is run directly instead of running after backup as usual. This unlikely combination of events means this is probably not a problem in the field.
* Fix segfault on unexpected EOF in gzip decompression. (Reported by Stephen Frost.)

2d10293d04 v2.19: C Migrations and Bug Fixes
Bug Fixes:

* Fix remote timeout in delta restore. When performing a delta restore on a largely unchanged cluster the remote could timeout if no files were fetched from the repository within protocol-timeout. Add keep-alives to prevent remote timeout. (Reported by James Sewell, Jens Wilke.)
* Fix handling of repeated HTTP headers. When HTTP headers are repeated they should be considered equivalent to a single comma-separated header rather than generating an error, which was the prior behavior. (Reported by donicrosby.)

Improvements:

* JSON output from the info command is no longer pretty-printed. Monitoring systems can more easily ingest the JSON without linefeeds. External tools such as jq can be used to pretty-print if desired. (Contributed by Cynthia Shang.)
* The check command is implemented entirely in C. (Contributed by Cynthia Shang.)

Documentation Improvements:

* Document how to contribute to pgBackRest. (Contributed by Cynthia Shang.)
* Document maximum version for auto-stop option. (Contributed by Brad Nicholson.)

Test Suite Improvements:

* Fix container test path being used when --vm=none. (Suggested by Stephen Frost.)
* Fix mismatched timezone in expect test. (Suggested by Stephen Frost.)
* Don't autogenerate embedded libc code by default. (Suggested by Stephen Frost.)

4629237d6a v2.18: PostgreSQL 12 Support
Features:

* PostgreSQL 12 support.
* Add info command set option for detailed text output. The additional details include databases that can be used for selective restore and a list of tablespaces and symlinks with their default destinations. (Contributed by Cynthia Shang. Suggested by Stephen Frost, ejberdecia.)
* Add standby restore type. This restore type automatically adds standby_mode=on to recovery.conf for PostgreSQL < 12 and creates standby.signal for PostgreSQL ≥ 12, creating a common interface between PostgreSQL versions. (Reviewed by Cynthia Shang.)

Improvements:

* The restore command is implemented entirely in C. (Reviewed by Cynthia Shang.)

Documentation Improvements:

* Document the relationship between db-timeout and protocol-timeout. (Contributed by Cynthia Shang. Suggested by James Chanco Jr.)
* Add documentation clarifications regarding standby repositories. (Contributed by Cynthia Shang.)
* Add FAQ for time-based Point-in-Time Recovery. (Contributed by Cynthia Shang.)

Bug Fixes:

* Fix archive retention expiring too aggressively. (Fixed by Cynthia Shang. Reported by Mohamad El-Rifai.)

Improvements:

* The expire command is implemented entirely in C. (Contributed by Cynthia Shang.)
* The local command for restore is implemented entirely in C.
* Remove hard-coded PostgreSQL user so $PGUSER works. (Suggested by Julian Zhang, Janis Puris.)
* Honor configure --prefix option. (Suggested by Daniel Westermann.)
* Rename repo-s3-verify-ssl option to repo-s3-verify-tls. The new name is preferred because pgBackRest does not support any SSL protocol versions (they are all considered to be insecure). The old name will continue to be accepted.

Documentation Improvements:

* Add FAQ to the documentation. (Contributed by Cynthia Shang.)
* Use wal_level=replica in the documentation for PostgreSQL ≥ 9.6. (Suggested by Patrick McLaughlin.)

ec9622cde8 Use the git log to ease release note management.
The release notes are generally a direct reflection of the git log.  So, ease the burden of maintaining the release notes by using the git log to determine what needs to be added.

Currently only non-dev items are required to be matched to a git commit but the goal is to account for all commits.

The git history cache is generated from the git log but can be modified to correct typos and match the release notes as they evolve.  The commit hash is used to identify commits that have already been added to the cache.

There's plenty more to do here.  For instance, links to the commits for each release item should be added to the release notes.

* Increase process-max limit to 999. (Suggested by Rakshitha-BR.)
* Improve error message when an S3 bucket name contains dots.

Documentation Improvements:

* Clarify that S3-compatible object stores are supported. (Suggested by Magnus Hagander.)

904550c97f v2.06: Checksum Delta Backup and PostgreSQL 11 Support
Bug Fixes:

* Fix missing missing URI encoding in S3 driver. (Reported by Dan Farrell.)
* Fix incorrect error message for duplicate options in configuration files. (Reported by Jesper St John.)
* Fix incorrectly reported error return in info logging. A return code of 1 from the archive-get was being logged as an error message at info level but otherwise worked correctly.

Features:

* Add checksum delta for incremental backups which uses checksums rather than timestamps to determine if files have changed. (Contributed by Cynthia Shang.)
* PostgreSQL 11 support, including configurable WAL segment size.

Improvements:

* Ignore all files in a linked tablespace directory except the subdirectory for the current version of PostgreSQL. Previously an error would be generated if other files were present and not owned by the PostgreSQL user.
* Improve info command to display the stanza cipher type. (Contributed by Cynthia Shang. Suggested by Douglas J Hunley.)
* Improve support for special characters in filenames.
* Allow delta option to be specified in the pgBackRest configuration file. (Contributed by Cynthia Shang.)

bc7462d86d v2.05: Environment Variable Options and Exclude Temporary/Unlogged Relations
Bug Fixes:

* Fix issue where relative links in $PGDATA could be stored in the backup with the wrong path. This issue did not affect absolute links and relative tablespace links were caught by other checks. (Reported by Cynthia Shang.)
* Remove incompletely implemented online option from the check command. Offline operation runs counter to the purpose of this command, which is to check if archiving and backups are working correctly. (Reported by Jason O'Donnell.)
* Fix issue where errors raised in C were not logged when called from Perl. pgBackRest properly terminated with the correct error code but lacked an error message to aid in debugging. (Reported by Douglas J Hunley.)
* Fix issue when a boolean option (e.g. delta) was specified more than once. (Reported by Yogesh Sharma.)

Features:

* Allow any option to be set in an environment variable. This includes options that previously could only be specified on the command line, e.g. stanza, and secret options that could not be specified on the command-line, e.g. repo1-s3-key-secret.
* Exclude temporary and unlogged relation (table/index) files from backup. Implemented using the same logic as the patches adding this feature to PostgreSQL, 8694cc96 and 920a5e50. Temporary relation exclusion is enabled in PostgreSQL ≥ 9.0. Unlogged relation exclusion is enabled in PostgreSQL ≥ 9.1, where the feature was introduced. (Contributed by Cynthia Shang.)
* Allow arbitrary directories and/or files to be excluded from a backup. Misuse of this feature can lead to inconsistent backups so read the --exclude documentation carefully before using. (Reviewed by Cynthia Shang.)
* Add log-subprocess option to allow file logging for local and remote subprocesses.
* PostgreSQL 11 Beta 3 support.

Improvements:

* Allow zero-size files in backup manifest to reference a prior manifest regardless of timestamp delta. (Contributed by Cynthia Shang.)
* Improve asynchronous archive-get/archive-push performance by directly checking status files. (Contributed by Stephen Frost.)
* Improve error message when a command is missing the stanza option. (Suggested by Sarah Conway.)

a8143ec125 v2.04: Critical Bug Fix for Backup Resume
IMPORTANT NOTE: This release fixes a critical bug in the backup resume feature. All resumed backups prior to this release should be considered inconsistent. A backup will be resumed after a prior backup fails, unless resume=n has been specified. A resumed backup can be identified by checking the backup log for the message "aborted backup of same type exists, will be cleaned to remove invalid files and resumed". If the message exists, do not use this backup or any backup in the same set for a restore and check the restore logs to see if a resumed backup was restored. If so, there may be inconsistent data in the cluster.

Bug Fixes:

* Fix critical bug in resume that resulted in inconsistent backups. A regression in v0.82 removed the timestamp comparison when deciding which files from the aborted backup to keep on resume. See note above for more details. (Reported by David Youatt, Yogesh Sharma, Stephen Frost.)
* Fix error in selective restore when only one user database exists in the cluster. (Fixed by Cynthia Shang. Reported by Nj Baliyan.)
* Fix non-compliant ISO-8601 timestamp format in S3 authorization headers. AWS and some gateways were tolerant of space rather than zero-padded hours while others were not. (Fixed by Andrew Schwartz.)

Features:

* PostgreSQL 11 Beta 2 support.

Improvements:

* Improve the HTTP client to set content-length to 0 when not specified by the server. S3 (and gateways) always set content-length or transfer-encoding but HTTP 1.1 does not require it and proxies (e.g. HAProxy) may not include either. (Suggested by Adam K. Sumner.)
* Set search_path = 'pg_catalog' on PostgreSQL connections. (Suggested by Stephen Frost.)

ee8aafb3ca v2.02: Parallel Asynchronous Archive Get and Configuration Includes
Bug Fixes:

* Fix directory syncs running recursively when only the specified directory should be synced. (Reported by Craig A. James.)
* Fix archive-copy throwing "path not found" error for incr/diff backups. (Reported by yummyliu, Vitaliy Kukharik.)
* Fix failure in manifest build when two or more files in PGDATA are linked to the same directory. (Reported by Vitaliy Kukharik.)
* Fix delta restore failing when a linked file is missing.
* Fix rendering of key/value and list options in help. (Reported by Clinton Adams.)

Features:

* Add asynchronous, parallel archive-get. This feature maintains a queue of WAL segments to help reduce latency when PostgreSQL requests a WAL segment with restore_command.
* Add support for additional pgBackRest configuration files in the directory specified by the --config-include-path option. Add --config-path option for overriding the default base path of the --config and --config-include-path option. (Contributed by Cynthia Shang.)
* Add repo-s3-token option to allow temporary credentials tokens to be configured. pgBackRest currently has no way to request new credentials so the entire command (e.g. backup, restore) must complete before the credentials expire. (Contributed by Yogesh Sharma.)

Improvements:

* Update the archive-push-queue-max, manifest-save-threshold, and buffer-size options to accept values in KB, MB, GB, TB, or PB where the multiplier is a power of 1024. (Contributed by Cynthia Shang.)
* Make backup/restore path sync more efficient. Scanning the entire directory can be very expensive if there are a lot of small tables. The backup manifest contains the path list so use it to perform syncs instead of scanning the backup/restore path.
* Show command parameters as well as command options in initial info log message.
* Rename archive-queue-max option to archive-push-queue-max to avoid confusion with the new archive-get-queue-max option. The old option name will continue to be accepted.

2a3d6ecde8 v2.01: Minor Bug Fixes and Improvements
Bug Fixes:

* Fix --target-action and --recovery-option options being reported as invalid when restoring with --type=immediate. (Reported by Brad Nicholson.)
* Immediately error when a secure option (e.g. repo1-s3-key) is passed on the command line. Since pgBackRest would not pass secure options on to sub-processes an obscure error was thrown. The new error is much clearer and provides hints about how to fix the problem. Update command documentation to omit secure options that cannot be specified on the command-line. (Reported by Brad Nicholson.)
* Fix issue passing --no-config to embedded Perl. (Reported by Ibrahim Edib Kokdemir.)
* Fix issue where specifying log-level-stderr > warn would cause a local/remote process to error on exit due to output found on stderr when none was expected. The max value for a local/remote process is now error since there is no reason for these processes to emit warnings. (Reported by Clinton Adams.)
* Fix manifest test in the check command when tablespaces are present. (Fixed by Cynthia Shang. Reported by Thomas Flatley.)

Improvements:

* Error when multiple arguments are set in the config file for an option that does not accept multiple arguments. (Contributed by Cynthia Shang.)
* Remove extraneous sudo commands from src/Makefile. (Contributed by Adrian Vondendriesch.)

13cdb75ac5 v2.00: Performance Improvements for Archive Push
Features:

* The archive-push command is now partially coded in C which allows the PostgreSQL archive_command to run significantly faster when processing status messages from the asynchronous archive process. (Reviewed by Cynthia Shang.)

Improvements:

* Improve check command to verify that the backup manifest can be built. (Contributed by Cynthia Shang.)
* Improve performance of HTTPS client. Buffering now takes the pending bytes on the socket into account (when present) rather than relying entirely on select(). In some instances the final bytes would not be flushed until the connection was closed.
* Improve S3 delete performance. The constant S3_BATCH_MAX had been replaced with a hard-coded value of 2, probably during testing.
* Allow any non-command-line option to be reset to default on the command-line. This allows options in pgbackrest.conf to be reset to default which reduces the need to write new configuration files for specific needs.
* The C library is now required. This eliminates conditional loading and eases development of new library features.
* The pgbackrest executable is now a C binary instead of Perl. This allows certain time-critical commands (like async archive-push) to run more quickly.
* Rename db-* options to pg-* and backup-* options to repo-* to improve consistency. repo-* options are now indexed although currently only one is allowed.

ba6b49ecb7 v1.26: Repository Encryption
Bug Fixes:

* Fixed an issue that could cause copying large manifests to fail during restore. (Reported by Craig A. James.)
* Fixed incorrect WAL offset for 32-bit architectures. (Fixed by Javier Wilson.)
* Fixed an issue retrieving WAL for old database versions. After a stanza-upgrade it should still be possible to restore backups from the previous version and perform recovery with archive-get. However, archive-get only checked the most recent db version/id and failed. Also clean up some issues when the same db version/id appears multiple times in the history. (Fixed by Cynthia Shang. Reported by Clinton Adams.)
* Fixed an issue with invalid backup groups being set correctly on restore. If the backup cannot map a group to a name it stores the group in the manifest as false then uses either the owner of $PGDATA to set the group during restore or failing that the group of the current user. This logic was not working correctly because the selected group was overwriting the user on restore leaving the group undefined and the user incorrectly set to the group. (Reported by Jeff McCormick.)
* Fixed an issue passing parameters to remotes. When more than one db was specified the path, port, and socket path would for db1 were passed no matter which db was actually being addressed. (Reported by Uspen.)

Features:

* Repository encryption support. (Contributed by Cynthia Shang, David Steele.)

85b35f30a4 v1.25: S3 Performance Improvements
Bug Fixes:

* Fix custom settings for compress-level option being ignored. (Reported by Jens Wilke.)
* Remove error when overlapping timelines are detected. Overlapping timelines are valid in many Point-in-Time-Recovery (PITR) scenarios. (Reported by blogh.)
* Fix instances where database-id was not rendered as an integer in JSON info output. (Fixed by Cynthia Shang. Reported by Jason O'Donnell.)

Features:

* Improve performance of list requests on S3. Any beginning literal portion of a filter expression is used to generate a search prefix which often helps keep the request small enough to avoid rate limiting. (Suggested by Mihail Shvein.)

Bug Fixes:

* Fixed an issue where warnings were being emitted in place of lower priority log messages during backup from standby initialization. (Reported by Uspen.)

Features:

* Exclude contents of pg_snapshots, pg_serial, pg_notify, and pg_dynshmem from backup since they are rebuilt on startup.
* Exclude pg_internal.init files from backup since they are rebuilt on startup.
