* This will help catch Perl errors in the doc code since it is not run across multiple OSs like the core and test code.
* It is to be hoped that a newer kernel will make Docker more stable.
Release notes are now broken into sections so that bugs, features, and refactors are clearly delineated. An "Additional Notes" section has been added for changes to documentation and the test suite that do not affect the core code.
The change log was the last piece of documentation to be rendered in Markdown only. Wrote a converter so the document can be output by the standard renderers. The change log will now be located on the website and has been renamed to "Releases".
Somewhere between perl 5.14 and 5.20, constructs like this:
perl -e '$a = {}; keys $a'
started to throw warnings:
keys on reference is experimental at -e line 1.
Fix by adding a bunch of %{} and @{} casts.
* Enhanced text output of `info` command to include timestamps, sizes, and the reference list for all backups. Contributed by Cynthia Shang.
* Allow selective restore of databases from a cluster backup. This feature can result in major space and time savings when only specific databases are restored. Unrestored databases will not be accessible but must be manually dropped before they will be removed from the shared catalogue.
* Experimental support for non-exclusive backups in PostgreSQL 9.6 beta1. Changes to the control/catalog/WAL versions in subsequent betas may break compatibility but pgBackRest will be updated with each release to keep pace.
Some files need to be added to the manifest after the initial build. This is currently done in only one place but usage will expand in the future so the functionality has been encapsulated in addFile().
Added database version constants and changed version identification code to use hash tables instead of if-else. Propagated the db version constants to the rest of the code and in passing fixed some path/filename constants.
Added new regression tests to check that specific files are never copied.
The join() used was not able to handle nulls and was replaced by a loop. An injudicious trim was removed when the source of extra linefeeds was determined to be an additional loop execution that was not handled correctly.
This feature can result in major space and time savings when only specific databases are restored. Unrestored databases will not be accessible but must be manually dropped before they will be removed from the shared catalogue.
This change assigns each version of PostgreSQL to a specific OS version for testing to minimize the number of tests being run. In general, older versions of PostgreSQL are assigned to older OS versions.
The old behavior can be enabled with `--db-version=all`.
This change allows for easier testing since all files are local on the host VM and can be easily accessed without using `docker exec`. In addition, this change is required to allow multiple Docker containers per test case which is coming soon.
Added a note to documentation that only 64-bit distributions are supported. It seems unlikely that anybody would be running a production server on anything else these days so we'll wait for a field report before taking further action.
* This flag day release breaks compatibility with older versions of pgBackRest. The manifest format, on-disk structure, configuration scheme, and the exe/path 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. Restores from the prior repository will require the prior version of pgBackRest but because of name changes it is possible to have 1.00 and a prior version of pgBackRest installed at the same time. See the notes below for more detailed information on what has changed.
* Implemented a new configuration scheme which should be far simpler to use. See the User Guide and Configuration Reference for details but for a simple configuration all options can now be placed in the stanza section. Options that are shared between stanzas can be placed in the [global] section. More complex configurations can still make use of command sections though this should be a rare use case.
* The repo-path option now always refers to the repository where backups and archive are stored, whether local or remote, so the repo-remote-path option has been removed. The new spool-path option can be used to define a location for queueing WAL segments when archiving asynchronously. A local repository is no longer required.
* The default configuration filename is now pgbackrest.conf instead of pg_backrest.conf. This was done for consistency with other naming changes but also to prevent old config files from being loaded accidentally when migrating to 1.00.
* The default repository name was changed from /var/lib/backup to /var/lib/pgbackrest.
* Lock files are now stored in /tmp/pgbackrest by default. These days /run/pgbackrest is the preferred location but that would require init scripts which are not part of this release. The lock-path option can be used to configure the lock directory.
* Log files are now stored in /var/log/pgbackrest by default and no longer have the date appended so they can be managed with logrotate. The log-path option can be used to configure the lock directory.
* Executable filename changed from pg_backrest to pgbackrest.
* All files and directories linked from PGDATA are now included in the backup. By default links will be restored directly into PGDATA as files or directories. The --link-all option can be used to restore all links to their original locations. The --link-map option can be used to remap a link to a new location.
* Removed --tablespace option and replaced with --tablespace-map-all option which should more clearly indicate its function.
* Added detail log level which will output more information than info without being as verbose as debug.

This makes make the migrated file functions available to parts of the code that don't have access to a File object. They still exist as wrappers in the File object to support remote calls.
* Specific VMs can now be built by using --vm along with --vm-build.
* Docker caching can be disabled with --vm-force.
* ControlMaster is now used for al VMs to improve test speed.
