4e7bd4468a Worked on issue #122: 9.5 Integration.
Most tests are working now.  What's not working:

1) --target-resume option fails because pause_on_recovery setting was removed.  Need to implement to the new 9.5 option and make that work with older versions in a consistent way.
2) No tests for the new .partial WAL segments that can be generated on timeline switch.

c568f5e727 v0.78: Remove CPAN dependencies, stability improvements
* Removed dependency on CPAN packages for multi-threaded operation.  While it might not be a bad idea to update the threads and Thread::Queue packages, it is no longer necessary.

* Added vagrant test configurations for Ubuntu 12.04 and CentOS 6.

* Modified wait backoffs to use a Fibonacci sequence rather than geometric.  This will make then grow less aggressively while still giving reasonable wait times.

* More options for regression tests and improved code to run in a variety of environments.

b1ded135df v0.77: CentOS/RHEL 6 support and protocol improvements
* Removed pg_backrest_remote and added the functionality to pg_backrest as remote command.

* Added file and directory syncs to the File object for additional safety during backup/restore and archiving.  Suggested by Andres Freund.

* Support for Perl 5.10.1 and OpenSSH 5.3 which are default for CentOS/RHEL 6.  Found by Eric Radman.

* Improved error message when backup is run without archive_command set and without --no-archive-check specified.  Found by Eric Radman.

* Moved version number out of the VERSION file to Version.pm to better support packaging.  Suggested by Michael Renner.

* Replaced IPC::System::Simple and Net::OpenSSH with IPC::Open3 to eliminate CPAN dependency for multiple distros.

1afbab010f v0.75: New repository format, info command and experimental 9.5 support
* IMPORTANT NOTE: This flag day release breaks compatibility with older versions of PgBackRest.  The manifest format, on-disk structure, and the binary names have all changed.  You must create a new repository to hold backups for this version of PgBackRest and keep your older repository for a time in case you need to do a restore.  The `pg_backrest.conf` file has not changed but you'll need to change any references to `pg_backrest.pl` in cron (or elsewhere) to `pg_backrest` (without the `.pl` extension).

* Add info command.

* More efficient file ordering for backup.  Files are copied in descending size order so a single thread does not end up copying a large file at the end.  This had already been implemented for restore.

* Logging now uses unbuffered output.  This should make log files that are being written by multiple threads less chaotic.  Suggested by Michael Renner.

* Experimental support for PostgreSQL 9.5.  This may break when the control version or WAL magic changes but will be updated in each release.

* Includes updating the manifest to format 4.  It turns out the manifest and .info files were not very good for providing information.  A format update was required anyway so worked through the backlog of changes that would require a format change.

* Multiple database versions are now supported in the archive.  Does't actually work yet but the structure should be good.

* Tests use more constants now that test logs can catch name regressions.

f83f0fa54d v0.70: Stability improvements for archiving, improved logging and help
* Fixed an issue where archive-copy would fail on an incr/diff backup when hardlink=n.  In this case the pg_xlog path does not already exist and must be created. Reported by Michael Renner

* Allow duplicate WAL segments to be archived when the checksum matches.  This is necessary for some recovery scenarios.

* Allow comments/disabling in pg_backrest.conf using #.  Suggested by Michael Renner.

* Better logging before pg_start_backup() to make it clear when the backup is waiting on a checkpoint.  Suggested by Michael Renner.

* Various command behavior, help and logging fixes.  Reported by Michael Renner.

* Fixed an issue in async archiving where archive-push was not properly returning 0 when archive-max-mb was reached and moved the async check after transfer to avoid having to remove the stop file twice.  Also added unit tests for this case and improved error messages to make it clearer to the user what went wrong.  Reported by Michael Renner.

* Fixed a locking issue that could allow multiple operations of the same type against a single stanza.  This appeared to be benign in terms of data integrity but caused spurious errors while archiving and could lead to errors in backup/restore. Reported by Michael Renner.

* Replaced JSON module with JSON::PP which ships with core Perl.

49fe40850f v0.65: Improved resume and restore logging, compact restores
* Better resume support.  Resumed files are checked to be sure they have not been modified and the manifest is saved more often to preserve checksums as the backup progresses.  More unit tests to verify each resume case.

* Resume is now optional.  Use the `resume` setting or `--no-resume` from the command line to disable.

* More info messages during restore.  Previously, most of the restore messages were debug level so not a lot was output in the log.

* Fixed an issue where an absolute path was not written into recovery.conf when the restore was run with a relative path.

* Added `tablespace` setting to allow tablespaces to be restored into the `pg_tblspc` path.  This produces compact restores that are convenient for development, staging, etc.  Currently these restores cannot be backed up as PgBackRest expects only links in the `pg_tblspc` path.

a9b9ec2492 v0.61: bug fix for uncompressed remote destination
* Fixed a buffering error that could occur on large, highly-compressible files when copying to an uncompressed remote destination.  The error was detected in the decompression code and resulted in a failed backup rather than corruption so it should not affect successful backups made with previous versions.

5185d49873 v0.60: better version support and WAL improvements
* Pushing duplicate WAL now generates an error.  This worked before only if checksums were disabled.

* Database System IDs are used to make sure that all WAL in an archive matches up.  This should help prevent misconfigurations that send WAL from multiple clusters to the same archive.

* Regression tests working back to PostgreSQL 8.3.

* Improved threading model by starting threads early and terminating them late.

b37d59832f v0.50: restore and much more
* Added restore functionality.

* All options can now be set on the command-line making pg_backrest.conf optional.

* De/compression is now performed without threads and checksum/size is calculated in stream.  That means file checksums are no longer optional.

* Added option `--no-start-stop` to allow backups when Postgres is shut down.  If `postmaster.pid` is present then `--force` is required to make the backup run (though if Postgres is running an inconsistent backup will likely be created).  This option was added primarily for the purpose of unit testing, but there may be applications in the real world as well.

* Fixed broken checksums and now they work with normal and resumed backups.  Finally realized that checksums and checksum deltas should be functionally separated and this simplied a number of things.  Issue #28 has been created for checksum deltas.

* Fixed an issue where a backup could be resumed from an aborted backup that didn't have the same type and prior backup.

* Removed dependency on Moose.  It wasn't being used extensively and makes for longer startup times.

* Checksum for backup.manifest to detect corrupted/modified manifest.

* Link `latest` always points to the last backup.  This has been added for convenience and to make restores simpler.

* More comprehensive unit tests in all areas.
