92e04ea9f4 Remove per-stanza repo cache clear during testing.
This was not being used and is not supported by the equivalent C code.

e3fe3434b4 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.

1bc84c6474 The local command for restore is implemented entirely in C.
This is just the part of restore run by the local helper processes, not the entire command.

Even so, various optimizations in the code (like pipelining and optimizations for zero-length files) should make the restore command faster on object stores.

cb00030ee3 Remove dead code missed in 1b486847.
This commit removed all Perl references to spool storage but some stuff was left behind.

1b48684713 The archive-push command is implemented entirely in C.
This new implementation should behave exactly like the old Perl code with the exception of updated log messages.

Remove as much of the Perl code as possible without breaking other commands.

d245f8eb42 The info command is implemented entirely in C.
The C info code has already been committed but this commit wires it into main.

Also remove the info Perl code and tests since they are no longer called.

b4146b6bff Update Perl repo rules to work when stanza is not specified.
The C storage object strives to use rules whenever possible instead of generating absolute paths.  This change helps the C and Perl storage work together via the protocol layer.

801e2a5a2c Rename PGBACKREST/BACKREST constants to PROJECT.
This brings consistency between the C and Perl constants and allows for easier code reuse.

b6b2c915b2 Allow hashSize() to run on remote storage.
Apparently we never needed to run this function remotely.

It will be needed by the backup checksum delta feature, so implement it now.

d41570c37a Improve log file names for remote processes started by locals.
The log-subprocess feature added in 22765670 failed to take into account the naming for remote processes spawned by local processes.  Not only was the local command used for the naming of log files but the process id was not pass through.  This meant every remote log was named "[stanza]-local-remote-000" which is confusing and meant multiple processes were writing to the same log.

Instead, pass the real command and process id to the remote.  This required a minor change in locking to ignore locks if process id is greater than 0 since remotes started by locals never lock.

6a40c916d4 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.

54dd6f3ed4 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.

27aa5f756e Add support for additional pgBackRest configuration files.
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.

f0250dab4b Move async forking and more error handling to C.
The Perl process was exiting directly when called but that interfered with proper locking for the forked async process. Now Perl returns results to the C process which handles all errors, including signals.

6fd0c3dcaa Improved lock implementation written in C.
Now only two types of locks can be taken: archive and backup. Most commands use one or the other but the stanza-* commands acquire both locks. This provides better protection than the old command-based locking scheme.

be90028100 Rename db-* options to pg-* and backup-* options to repo-* to improve consistency.
* repo-* options are now indexed although only one is allowed.
* List deprecated option names in documentation and command-line help.

74d6398ad2 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.

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.

eb4918d018 Fixed locking bug and refactoring.
* Fixed an issue where read-only operations that used local worker processes (i.e. restore) were creating write locks that could interfere with parallel archive-push. (Reported by Jens Wilke.)
* Simplify locking scheme. Now, only the master process will hold write locks (archive-push, backup) and not all the local and remote worker processes as before.
