Timeout used for connections and read/write operations.
Note that the entire read/write operation does not need to complete within this timeout but some progress must be made, even if it is only a single byte.
This is really a socket option so the new name is clearer.
Since common/io/socket/tcp will contains a mix of options it makes sense to rename it to socket and cascade name changes as needed.
Prior to 2.25 the individual TCP keep-alive options were not being configured due to a missing header. In 2.25 they were being configured incorrectly due to a disconnect between the timeout specified in ms and what was expected by the TCP options, i.e. seconds.
Instead make the TCP keep-alive options directly configurable, with correct units and better testing. Keep-alive is enabled by default (though it can be defaulted to the system setting instead) and the rest of the options are not set by default. This is in line with what PostgreSQL does, though PostgreSQL does not allow keep-alive to be defaulted.
Also move configuration of TCP options before connect() as PostgreSQL does.
LZ4 compresses data faster than gzip but at a lower ratio. This can be a good tradeoff in certain scenarios.
Note that setting compress-type=lz4 will make new backups and archive incompatible (unrestorable) with prior versions of pgBackRest.
These commands are generally useful but more importantly they allow removing LibC by providing the Perl integration tests an alternate way to work with repository storage.
All the commands are currently internal only and should not be used on production repositories.
This command only makes sense for the repository storage since other storage (e.g. pg and spool) must be located on a local Posix filesystem and can be listed using standard unix commands. Since the repo storage can be located lots of places having a common way to list it makes sense.
Prefix with repo- to make the scope of this command clear.
Update documentation to reflect this change.
Add compress-type option and deprecate compress option. Since the compress option is boolean it won't work with multiple compression types. Add logic to cfgLoadUpdateOption() to update compress-type if it is not set directly. The compress option should no longer be referenced outside the cfgLoadUpdateOption() function.
Add common/compress/helper module to contain interface functions that work with multiple compression types. Code outside this module should no longer call specific compression drivers, though it may be OK to reference a specific compression type using the new interface (e.g., saving backup history files in gz format).
Unit tests only test compression using the gz format because other formats may not be available in all builds. It is the job of integration tests to exercise all compression types.
Additional compression types will be added in future commits.
Although path-style URIs have been deprecated by AWS, they may still be used with products like Minio because no additional DNS configuration is required.
Path-style URIs must be explicitly enabled since it is not clear how they can be auto-detected reliably. More importantly, faulty detection could cause regressions in current installations.
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.
This should have been removed when the support for the option was removed in c7333190.
The option cannot be removed entirely because we don't want to error in the case where --force was specified but the stanza is valid.
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.
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.
These features finally make the ls command practical.
Currently the JSON contains only name, type, and size. We may add more fields in the future, but these seem like the minimum needed to be useful.
If this option is set then ports appended to repo-s3-endpoint or repo-s3-host will be ignored.
Setting this option explicitly may be the only way to use a bare ipv6 address with S3 (since multiple colons confuse the parser) but we plan to improve this in the future.
Allow commands to be skipped by default in the command help but still work if help is requested for the command directly. There may be other uses for the flag in the future.
Update help for ls now that it is exposed.
Allows listing repo paths/files from the command-line, to be used primarily for testing and debugging.
This command is internal-only so the interface may change at any time without notice.
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.
Admonitions call out places where the user should take special care.
Support added for HTML, PDF, Markdown and help text renderers. XML files have been updated accordingly.

Use checksums rather than timestamps to determine if files have changed. This is useful in cases where the timestamps may not be trustworthy, e.g. when performing an incremental after failing over to a standby.
If checksum delta is enabled then checksums will be used for verification of resumed backups, even if they are full. Resumes have always used checksums to verify the files in the repository, enabling delta performs checksums on the database files as well.
Note that the user must manually enable this feature in cases were it would be useful or just keep in enabled all the time. A future commit will address automatically enabling the feature in cases where it seems likely to be useful.

This option was previously allowed on the command-line only for no particular reason that we could determine.
Being able to specify it in the config file seems like a good idea and won't change current usage.

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.
pgBackRest currently has no way to request new credentials so the entire command (e.g. backup, restore) must complete before the credentials expire.

Configuration files are loaded from 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.
