This is consistent with the way BackRest and BackRest test were renamed way back in 18fd2523.
More modules will be moving to pgBackRestDoc soon so renaming now reduces churn later.
This directory was once the home of the production Perl code but since f0ef73db this is no longer true.
Move the modules to test in most cases, except where the module is expected to be useful for the doc engine beyond the expected lifetime of the Perl test code (about a year if all goes well).
The exception is pgBackRest::Version which requires more work to migrate since it is used to track pgBackRest versions.
This was the interface between Perl and C introduced in 36a5349b but since f0ef73db has only been used by the Perl integration tests. This is expensive code to maintain just for testing.
The main dependency was the interface to storage, no matter where it was located, e.g. S3. Replace this with the new-introduced repo commands (d3c83453) that allow access to repo storage via the command line.
The other dependency was on various cfgOption* functions and CFGOPT_ constants that were convenient but not necessary. Replace these with hard-coded strings in most places and create new constants for commonly used values.
Remove all auto-generated Perl code. This means that the error list will no longer be maintained automatically so copy used errors to Common::Exception.pm. This file will need to be maintained manually going forward but there is not likely to be much churn as the Perl integration tests are being retired.
Update test.pl and related code to remove LibC builds.
Ding, dong, LibC is dead.
Bug Fixes:
* Fix remote timeout in delta restore. When performing a delta restore on a largely unchanged cluster the remote could timeout if no files were fetched from the repository within protocol-timeout. Add keep-alives to prevent remote timeout. (Reported by James Sewell, Jens Wilke.)
* Fix handling of repeated HTTP headers. When HTTP headers are repeated they should be considered equivalent to a single comma-separated header rather than generating an error, which was the prior behavior. (Reported by donicrosby.)
Improvements:
* JSON output from the info command is no longer pretty-printed. Monitoring systems can more easily ingest the JSON without linefeeds. External tools such as jq can be used to pretty-print if desired. (Contributed by Cynthia Shang.)
* The check command is implemented entirely in C. (Contributed by Cynthia Shang.)
Documentation Improvements:
* Document how to contribute to pgBackRest. (Contributed by Cynthia Shang.)
* Document maximum version for auto-stop option. (Contributed by Brad Nicholson.)
Test Suite Improvements:
* Fix container test path being used when --vm=none. (Suggested by Stephen Frost.)
* Fix mismatched timezone in expect test. (Suggested by Stephen Frost.)
* Don't autogenerate embedded libc code by default. (Suggested by Stephen Frost.)
Bug Fixes:
* Improve slow manifest build for very large quantities of tables/segments. (Reported by Jens Wilke.)
* Fix exclusions for special files. (Reported by CluelessTechnologist, Janis Puris, Rachid Broum.)
Improvements:
* The stanza-create/update/delete commands are implemented entirely in C. (Contributed by Cynthia Shang.)
* The start/stop commands are implemented entirely in C. (Contributed by Cynthia Shang.)
* Create log directories/files with 0750/0640 mode. (Suggested by Damiano Albani.)
Documentation Bug Fixes:
* Fix yum.p.o package being installed when custom package specified. (Reported by Joe Ayers, John Harvey.)
Documentation Improvements:
* Build pgBackRest as an unprivileged user. (Suggested by Laurenz Albe.)
Bug Fixes:
* Remove request for S3 object info directly after putting it. (Reported by Matt Kunkel.)
* Correct archive-get-queue-max to be size type. (Reported by Ronan Dunklau.)
* Add error message when current user uid/gid does not map to a name. (Reported by Camilo Aguilar.)
* Error when --target-action=shutdown specified for PostgreSQL < 9.5.
Improvements:
* Set TCP keepalives on S3 connections. (Suggested by Ronan Dunklau.)
* Reorder info command text output so most recent backup is output last. (Contributed by Cynthia Shang. Suggested by Ryan Lambert.)
* Change file ownership only when required.
* Redact authentication header when throwing S3 errors. (Suggested by Brad Nicholson.)
Bug Fixes:
* Fix potential buffer overrun in error message handling. (Reported by Lætitia.)
* Fix archive write lock being taken for the synchronous archive-get command. (Reported by Uspen.)
Improvements:
* Embed exported C functions and Perl modules directly into the pgBackRest executable.
* Use time_t instead of __time_t for better portability. (Suggested by Nick Floersch.)
* Print total runtime in milliseconds at command end.
