This makes it easier to create objects and then copy them to another context when they are complete without having to worry about freeing them on error. Update List, StringList, and Buffer to allow moves. Update Ini and Storage to take advantage of moves.
Scanning the entire backup directory can be very expensive if there are a lot of small tables. The backup manifest contains the backup directory list so use it to perform syncs instead of scanning the backup directory.
* Perform apt-get update to ensure packages are up to date before installing.
* Add -p to the repository mkdir so it won't fail if the directory already exists, handy for testing packages.
Switch from Devel::Cover because it would not report on branch coverage for reports converted from gcov.
Branch coverage is not complete, so for the time being errors will only be generated when statement coverage is not complete. Coverage of unit tests is not displayed in the report unless they are incomplete for either statement or branch coverage.
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.)

* Replace remaining NDEBUG blocks with the more granular DEBUG_UNIT.
* Remove some debug memset() calls in MemContext since valgrind is more useful for these checks.
Move command begin to C except when it must be called after another command in Perl (e.g. expire after backup). Command begin logs correctly for complex data types like hash and list. Specify which commands will log to file immediately and set the default log level for log messages that are common to all commands. File logging is initiated from C.
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.
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.
The host-*-ip variable is created from the id param so the name param can be changed without affecting the host-*-ip variable. If id is not specified then it is copied from name.
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.
* Check both doc-path and bin-path for logo.
* Allow PDF to be output to a location other than the output directory.
* Use PDF-specific version variable for more flexible formatting.
1) Error when the same option is defined multiple times in a section using alternate names.
2) Fix logging of invalid command error.
3) Warn when a stanza-only option is in a global section.
Also, make a note to add validation of section names to the check command.
Per review by Cynthia Shang.
The log-level-console option should not be changed in the parent process. Even though it is harmless at the moment, that may not always be true.
Per review by Cynthia Shang.
This provides correct matching in the event there are system-id and db-version duplicates (e.g. after reverting a pg_upgrade).
Fixed by Cynthia Shang.
Reported by Adam K. Sumner.
This allows specific options in pgbackrest.conf to be ignored (and set to default) which reduces the need to write new configuration files for specific needs.
Note that boolean, non-command-line options are already negatable.
When a backup host is present, backups should only be allowed on the backup host and restores should only be allowed on the database host unless an alternate configuration is created that ignores the remote host.
Reported by Lardière Sébastien.
Required to test restores on the backup server, a fairly common scenario.
Improve the restore function to accept optional parameters rather than a long list of parameters. In passing, clean up extraneous use of strType and strComment variables.
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.)
