* Fixed an issue where resumed compressed backups were not preserving existing files.
* Fixed an issue where resume and incr/diff would not ensure that the prior backup had the same compression and hardlink settings.
* Fixed an issue where a cold backup using --no-start-stop could be started on a running PostgreSQL cluster without --force specified.
* Fixed an issue where a thread could be started even when none were requested.
* Fixed an issue where the pgBackRest version number was not being updated in backup.info and archive.info after an upgrade/downgrade.
* Fixed an issue where the info command was throwing an exception when the repository contained no stanzas. Reported by Stephen Frost.
* Fixed an issue where the PostgreSQL pg_stop_backup() NOTICEs were being output to stderr. Reported by Stephen Frost.
* Renamed recovery-setting option and section to recovery-option to be more consistent with pgBackRest naming conventions.
* Command-line help is now extracted from the same XML source that is used for the other documentation and includes much more detail.
* Code cleanup and refactoring to standardize on patterns that have evolved over time.
* Added dynamic module loading to speed up commands, especially asynchronous archiving.
* Expiration tests are now synthetic rather than based on actual backups. This will allow development of more advanced expiration features.
* Experimental support for PostgreSQL 9.5 alpha2. This may break when the control version or WAL magic changes in future versions but will be updated in each pgBackRest release to keep pace. All regression tests pass except for --target-resume tests (this functionality has changed in 9.5) and there is no testing yet for .partial WAL segments.
Unable to reproduce this anymore. It seems to have been fixed with the last round of config changes. Add regression tests to make sure it doesn't happen again.
* Fixed an issue that caused the formatted timestamp for both the oldest and newest backups to be reported as the current time by the info command. Only text output was affected -- json output reported the correct epoch values. Reported by Michael Renner.
* Fixed protocol issue that was preventing ssh errors (especially on connection) from being logged.
* Now using Perl DBI and DBD::Pg for connections to PostgreSQL rather than psql. The cmd-psql and cmd-psql-option settings have been removed and replaced with db-port and db-socket-path.
* Add stop-auto option to allow failed backups to automatically be stopped when a new backup starts.
* Add db-timeout option to limit the amount of time pgBackRest will wait for pg_start_backup() and pg_stop_backup() to return.
* Remove pg_control file at the beginning of the restore and copy it back at the very end. This prevents the possibility that a partial restore can be started by PostgreSQL.
* The repository is now created and updated with consistent directory and file modes. By default umask is set to 0000 but this can be disabled with the neutral-umask setting.
* Added checks to be sure the db-path setting is consistent with db-port by comparing the data_directory as reported by the cluster against the db-path setting and the version as reported by the cluster against the value read from pg_control. The db-socket-path setting is checked to be sure it is an absolute path.
* Experimental support for PostgreSQL 9.5 alpha1. This may break when the control version or WAL magic changes in future versions but will be updated in each pgBackRest release to keep pace. All regression tests pass except for --target-resume tests (this functionality has changed in 9.5) and there is no testing yet for .partial WAL segments.
* Major refactoring of the protocol layer to support future development.
* Added vagrant test configurations for Ubuntu 14.04 and CentOS 7.
* Split most of README.md out into USERGUIDE.md and CHANGELOG.md because it was becoming unwieldy. Changed most references to "database" in the user guide to "database cluster" for clarity.
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.
* Major refactoring of the protocol layer to support this work.
* Fixed protocol issue that was preventing ssh errors (especially connect) from being logged.
On some systems the JSON->encode() function was adding a linefeed and on others it was not. This was causing regression test failures in in the test logs and may have also been inconvenient for users.
* 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.
* 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.
Replaced IPC::System::Simple and Net::OpenSSH with IPC::Open3 to eliminate CPAN dependency for multiple distros. Using open3 will also be used for local processes so it make sense to switch now.
Also stopped replacing FORMAT number which explains the large number of test log changes. FORMAT should change very rarely and cause test log failures when it does.
More separation of the protocol and remote layers than was done in issue #106.
Settings are passed to the remote via command-line parameters rather than in the protocol.
* 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.
