Bug Fixes:
* Fix resume after partial delete of backup by prior resume. (Reviewed by Cynthia Shang. Reported by Tom Swartz.)
Features:
* Add repo-ls command. (Reviewed by Cynthia Shang, Stefan Fercot.)
* Add repo-get command. (Contributed by Stefan Fercot, David Steele. Reviewed by Cynthia Shang.)
* Add archive-mode-check option. (Contributed by Stefan Fercot. Reviewed by David Steele, Michael Banck.)
Improvements:
* Improve archive-get performance. (Reviewed by Cynthia Shang.)
The C code does not use doubles to represent seconds like the Perl code did so time can be represented as an integer which reduces the number of data types that config has to understand.
Also remove Variant doubles since they are no longer used.
Note that not all double code was removed since we still need to display times to the user in seconds and it is possible for the times to be fractional. In the future this will likely be simplified by storing the original user input and using that value when the time needs to be displayed.
Bug Fixes:
* Allow [, #, and space as the first character in database names. (Reviewed by Stefan Fercot, Cynthia Shang. Reported by Jefferson Alexandre.)
* Create standby.signal only on PostgreSQL 12 when restore type is standby. (Fixed by Stefan Fercot. Reviewed by David Steele. Reported by Keith Fiske.)
Features:
* Expire history files. (Contributed by Stefan Fercot. Reviewed by David Steele.)

* Move info command text to the reference and link to user guide. (Reviewed by Cynthia Shang. Suggested by Christophe Courtois.)
* Update yum repository path for CentOS/RHEL user guide. (Contributed by Heath Lord. Reviewed by David Steele.)
Bug Fixes:

* Fix issue with = character in file or database names. (Reviewed by Bastian Wegge, Cynthia Shang. Reported by Brad Nicholson, Bastian Wegge.)
Features:
* Automatically retrieve temporary S3 credentials on AWS instances. (Contributed by David Steele, Stephen Frost. Reviewed by Cynthia Shang, David Youatt, Aleš Zelený, Jeanette Bromage.)
* Add archive-mode option to disable archiving on restore. (Reviewed by Stephen Frost. Suggested by Stephen Frost.)

* Fix typo in repo-cipher-type option reference. (Fixed by Don Seiler. Reviewed by David Steele.)
Documentation Improvements:
* Clarify that expire must be run regularly when expire-auto is disabled. (Reviewed by Douglas J Hunley. Suggested by Douglas J Hunley.)
We use the Z suffix in many functions to indicate that we are expecting a zero-terminated string so make this function conform to the pattern.
As a bonus the new name is a bit shorter, which is a good quality in a commonly-used function.
Bug Fixes:
* Fix restore --force acting like --force --delta. This caused restore to replace files based on timestamp and size rather than overwriting, which meant some files that should have been updated were left unchanged. Normal restore and restore --delta were not affected by this issue. (Reviewed by Cynthia Shang.)
Features:
* Azure support for repository storage. (Reviewed by Cynthia Shang, Don Seiler.)
* Add expire-auto option. This allows automatic expiration after a successful backup to be disabled. (Contributed by Stefan Fercot. Reviewed by Cynthia Shang, David Steele.)
Improvements:
* Asynchronous S3 multipart upload. (Reviewed by Stephen Frost.)
* Automatic retry for backup, restore, archive-get, and archive-push. (Reviewed by Cynthia Shang.)
* Disable query parallelism in PostgreSQL sessions used for backup control. (Reviewed by Stefan Fercot.)
* PostgreSQL 13 beta2 support. Changes to the control/catalog/WAL versions in subsequent betas may break compatibility but pgBackRest will be updated with each release to keep pace.
* Improve handling of invalid HTTP response status. (Reviewed by Cynthia Shang.)
* Improve error when pg1-path option missing for archive-get command. (Reviewed by Cynthia Shang.)
* Add hint when checksum delta is enabled after a timeline switch. (Reviewed by Matt Bunter, Cynthia Shang.)
* Use PostgreSQL instead of postmaster where appropriate. (Reviewed by Cynthia Shang.)
Documentation Bug Fixes:
* Fix incorrect example for repo-retention-full-type option. (Reported by Höseyin Sönmez.)
* Remove internal commands from HTML and man command references. (Reported by Cynthia Shang.)
Documentation Improvements:
* Update PostgreSQL versions used to build user guides. Also add version ranges to indicate that a user guide is accurate for a range of PostgreSQL versions even if it was built for a specific version. (Reviewed by Stephen Frost.)
* Update FAQ for expiring a specific backup set. (Contributed by Cynthia Shang. Reviewed by David Steele.)
* Update FAQ to clarify default PITR behavior. (Contributed by Cynthia Shang. Reviewed by David Steele.)
Bug Fixes:
* Fix issue checking if file links are contained in path links. (Reviewed by Cynthia Shang. Reported by Christophe Cavallié.)
* Allow pg-path1 to be optional for synchronous archive-push. (Reviewed by Cynthia Shang. Reported by Jerome Peng.)
* The expire command now checks if a stop file is present. (Fixed by Cynthia Shang. Reviewed by David Steele.)
* Handle missing reason phrase in HTTP response. (Reviewed by Cynthia Shang. Reported by Tenuun.)
* Increase buffer size for lz4 compression flush. (Reviewed by Cynthia Shang. Reported by Eric Radman.)

* Fix possibly missing pg1-* options for the remote command. (Reviewed by Cynthia Shang. Reported by Andrew L'Ecuyer.)
Features:
* Time-based retention for full backups. The --repo-retention-full-type option allows retention of full backups based on a time period, specified in days. (Contributed by Cynthia Shang, Pierre Ducroquet. Reviewed by David Steele.)
* Ad hoc backup expiration. Allow the user to remove a specified backup regardless of retention settings. (Contributed by Cynthia Shang. Reviewed by David Steele.)
* Zstandard compression support. Note that setting compress-type=zst will make new backups and archive incompatible (unrestorable) with prior versions of pgBackRest. (Reviewed by Cynthia Shang.)
* bzip2 compression support. Note that setting compress-type=bz2 will make new backups and archive incompatible (unrestorable) with prior versions of pgBackRest. (Contributed by Stephen Frost. Reviewed by David Steele, Cynthia Shang.)
* Add backup/expire running status to the info command. (Contributed by Stefan Fercot. Reviewed by David Steele.)
Improvements:
* Expire WAL archive only when repo-retention-archive threshold is met. WAL prior to the first full backup was previously expired after the first full backup. Now it is preserved according to retention settings. (Contributed by Cynthia Shang. Reviewed by David Steele.)
* Add local MD5 implementation so S3 works when FIPS is enabled. (Reviewed by Cynthia Shang, Stephen Frost. Suggested by Brian Almeida, John Kelley.)
* PostgreSQL 13 beta1 support. Changes to the control/catalog/WAL versions in subsequent betas may break compatibility but pgBackRest will be updated with each release to keep pace. (Reviewed by Cynthia Shang.)
* Reduce buffer-size default to 1MiB. (Reviewed by Stephen Frost.)
* Throw user-friendly error if expire is not run on repository host. (Contributed by Cynthia Shang. Reviewed by David Steele.)
Bug Fixes:
* Remove empty subexpression from manifest regular expression. MacOS was not happy about this though other platforms seemed to work fine. (Fixed by David Raftis.)
Improvements:
* Non-blocking TLS implementation. (Reviewed by Slava Moudry, Cynthia Shang, Stephen Frost.)
* Only limit backup copy size for WAL-logged files. The prior behavior could possibly lead to postgresql.conf or postgresql.auto.conf being truncated in the backup. (Reviewed by Cynthia Shang.)
* TCP keep-alive options are configurable. (Suggested by Marc Cousin.)
* Add io-timeout option.
When the Vagrant file was updated to use pgbackrest/ vs /backrest/ as the location for executing tests and building the documentation, parts of the contributing.xml (and hence the CONTRIBUTING.md) were not updated since some parts of the document are not actually executed when the CONTRIBUTING.md is built from contributing.xml: those parts that are executed were updated but those parts that are not executed were not.
This commit fixes the contributing.xml issue but also removes test/README.md as its contents were out of date and redundant given that they are covered in CONTRIBUTING.md.
This macro was created before the String object existed so subsequent usage with String always included a lot of strPtr() wrapping.
TEST_RESULT_STR_Z() had already been introduced but a wholesale replacement of TEST_RESULT_STR() was not done since the priority was on the C migration.
Update all calls to (old) TEST_RESULT_STR() with one of the following variants: (new) TEST_RESULT_STR(), TEST_RESULT_STR_Z(), TEST_RESULT_Z(), TEST_RESULT_Z_STR().
Adding a dummy column which is always set by the P() macro allows a single macro to be used for parameters or no parameters without violating C's prohibition on the {} initializer.
-Wmissing-field-initializers remains disabled because it still gives wildly different results between versions of gcc.
This documentation shows how to build a development environment on Ubuntu 19.04 and should work for other Debian-based distros.
Note that this document is not included in automated testing due to some unresolved issues with Docker in Docker on Travis CI. We'll address this in the future when we add contributing documentation to the website.
