d90b2724f8 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.

a1c13a50dd The check command is implemented entirely in C.
Note that building the manifest on each host has been temporarily removed.

This feature will likely be brought back as a non-default option (after the manifest code has been fully migrated to C) since it can be fairly expensive.

29e132f5e9 PostgreSQL 12 support.
Recovery settings are now written into postgresql.auto.conf instead of recovery.conf.  Existing recovery_target* settings will be commented out to help avoid conflicts.

A comment is added before recovery settings to identify them as written by pgBackRest since it is unclear how, in general, old settings will be removed.

recovery.signal and standby.signal are automatically created based on the recovery settings.

f96c54c4ba 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.

This information is not included in the JSON output because it requires reading the manifest which is too IO intensive to do for all manifests.  We plan to include this information for JSON in a future release.

c41fb575fb Add standby restore type.
This restore type automatically adds standby_mode=on to recovery.conf.

This could be accomplished previously by setting --recovery-option=standby_mode=on but PostgreSQL 12 requires standby mode to be enabled by a special file named standby.signal.

The new restore type allows us to maintain a common interface between PostgreSQL versions.

8979336819 Comment out unprivileged user documentation.

451ae397be The restore command is implemented entirely in C.
For the most part this is a direct migration of the Perl code into C.

There is one important behavioral change with regard to how file permissions are handled.  The Perl code tried to set ownership as it was in the manifest even when running as an unprivileged user.  This usually just led to errors and frustration.

The C code works like this:

If a restore is run as a non-root user (the typical scenario) then all files restored will belong to the user/group executing pgBackRest. If existing files are not owned by the executing user/group then an error will result if the ownership cannot be updated to the executing user/group. In that case the file ownership will need to be updated by a privileged user before the restore can be retried.

If a restore is run as the root user then pgBackRest will attempt to recreate the ownership recorded in the manifest when the backup was made. Only user/group names are stored in the manifest so the same names must exist on the restore host for this to work. If the user/group name cannot be found locally then the user/group of the PostgreSQL data directory will be used and finally root if the data directory user/group cannot be mapped to a name.

4815752ccc Add Perl interface to C storage layer.
Maintaining the storage layer/drivers in two languages is burdensome.  Since the integration tests require the Perl storage layer/drivers we'll need them even after the core code is migrated to C.  Create an interface layer so the Perl code can be removed and new storage drivers/features introduced without adding Perl equivalents.

The goal is to move the integration tests to C so this interface will eventually be removed.  That being the case, the interface was designed for maximum compatibility to ease the transition.  The result looks a bit hacky but we'll improve it as needed until it can be retired.

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.)

* 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.

d4418e7764 Rename pg-primary and pg-standby variables to pg1 and pg2.
It would be better if the hostnames were also pg1 and pg2 to illustrate that primaries and standbys can change hosts, but at this time the configuration ends up being confusing since pg1, pg2, etc. are also used in the option naming.  So, for now leave the names as pg-primary and pg-standby to avoid confusion.

72cbb9a9d4 Call Perl with built-in interpreter instead of execvp().
Exec'ing Perl worked fine but generated a very large command line in the process list and potentially exposed secrets.
