Double spaces have fallen out of favor in recent years because they no longer contribute to readability.
We have been using single spaces and editing related paragraphs for some time, but now it seems best to update the remaining instances to avoid churn in unrelated commits and to make it clearer what spacing contributors should use.
Ubuntu 18.04 will be EOL before the next release, so update to the oldest available Debian version.
Also fix one incorrect return value type, a test cast, and adjust some test timeouts.
Our new policy is to support ten versions of PostgreSQL, the five supported releases and the last five EOL releases. As of PostgreSQL 15, that means 9.0/9.1/9.2 are no longer supported by pgBackRest.
Remove all logic associated with 9.0/9.1/9.2 and update the tests.
Document the new support policy.
Update InfoPg to read/write control versions for the history in backup.info, since we can no longer rely on the mappings being available. In theory this could have been an issue after removing 8.3/8.4 if anybody was using a version that old.
The C test harness is used for unit tests from the Perl harness where possible. Currently, unit tests can be run in the C harness when --no-coverage is specified and --profile is not specified.
C harness tests work on meson 0.45.
The C harness runs with valgrind by default. Valgrind can be disabled with --no-valgrind.
Also rebuild containers to add meson and update the documentation so that meson builds will work (even though we don't do them yet).
Both have newer gcc and OpenSSL 3.
Fedora 36 runs horribly slow with valgrind enabled so run the valgrind tests on Ubuntu 22.04. Fedora 36 has a newer gcc so it is still worth testing on.
Remove VM_OS_REPO since it is no longer required.
Rebalance PostgreSQL versions for more efficient test times.
Always print version of PostgreSQL when testing. This helps verify that new minor releases are being used.
PostgreSQL 15 drops support for exclusive backup and renames the start/stop backup commands.
This is based on the pgdg-testing repo since beta1 has not been released yet, but it seems unlikely that breaking changes will be made at this point. beta1 should be tagged just before our next release so we'll retest before the release.
The /etc/profile.d/lang.sh script was causing issues but it does not exist on amd64, so it seems the easiest thing was to remove it.
Fix how 32-bit VMs are determined now that another 64-bit architecture has been added.
And remove some obsolete VM hashes.
Since CentOS 8 will be EOL at the end of the year it makes sense to do this now. The centos:8 image is still used in documentation.xml because changes there require manual testing, which will need to be done at a later date. The changes are not user-facing, however, and can be done at any time.
Also update CentOS references to RHEL since that is what we are emulating for testing purposes.
The newer version of valgrind helps with some arm64 issues that have been fixed since the architecture has become more popular. Also add the valgrind builds to the Vagrantfile and Dockerfile.
Move the CA cert install from the base container to the test container. This means the CA cert can be changed without rebuilding all the base containers.
Update Ubuntu 12.04 to 16.04. Version 16.04 is recently EOL but testing on an old version is beneficial.
Update Ubuntu 18.04 to 20.04.
Update Fedora 32 to 33. Version 34 would have been preferred but there were some build issues, i.e. the default shell did not work with configure, and after ksh was installed configure locked up.
Add --no-install-recommends to apt-get commands to save a bit of time and space.
Update test Dockerfile to run in multiple steps. This makes the container larger but also makes rebuilding after changes faster. The --squash option may be used to keep the container small.
Remove obsolete casts in protocol/parallel module. These casts were included in the original migration because Ubuntu 12.04 32-bit gcc required them, but Ubuntu 16.04 32-bit gcc complains. There is no production issue here since at this point in the code the file descriptors are guaranteed to be >= 0.
There are no code changes from PostgreSQL 13 so simply add the new version.
Add CATALOG_VERSION_NO_MAX to allow the catalog version to "float" during the PostgreSQL beta/rc period so new pgBackRest versions are not required when the catalog version changes.
Update the integration tests to handle new PostgreSQL startup messages.
The tests worked fine on multiple architectures, but would only run "bare metal", i.e. tests that required containers could not be run.
Enable basic multi-architecture support by allowing containers to be built using whatever architecture the host supports. Also allow cached containers to be defined for multiple architectures in container.yaml.
Add a Dockerfile which can be used as a container for other containers to provide a consistent development environment.
The primary goal is to allow development on Mac M1 but other architectures should find these improvements useful.
CentOS6 EOL'd and the mirrors were swiftly deleted, leading to failures in tests and documentation.
Remove CentOS 6 for now to get builds going again with the intention to replace it in the near future with CentOS 8.
Add older PostgreSQL versions to the u18 container that were not available before.
This also updates all minor versions for prior versions of PostgreSQL.
There don't appear to be any behavioral changes since PostgreSQL 12 and all the tests pass.
Changes to the control/catalog/WAL versions in subsequent betas may break compatibility but pgBackRest will be updated with each release to keep pace.

bzip2 is a widely available, high-quality data compressor. It typically compresses files to within 10% to 15% of the best available techniques (the PPM family of statistical compressors), while being around twice as fast at compression and six times faster at decompression.
bzip2 is currently available on all supported platforms.
Zstandard is a fast lossless compression algorithm targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library.
Zstandard version >= 1.0 is required, which is generally only available on newer distributions.
LZ4 compresses data faster than gzip but at a lower ratio. This can be a good tradeoff in certain scenarios.
Note that setting compress-type=lz4 will make new backups and archive incompatible (unrestorable) with prior versions of pgBackRest.
pkg-config is a generic way to get build options rather than relying on a package-specific utility.
XML2_CONFIG can be used to override this utility for systems that do not ship pkg-config.
Installing lcov 1.14 everywhere turned out to be a problem just as using 1.13 on Ubuntu 19.04 was.
Since we primarily use Ubuntu 18.04 for coverage testing and reporting, we definitely want to make sure that works. So, revert to using the default packaged lcov except when specified otherwise in VmTest.pm.
PostgreSQL minor version releases are also included since all containers have been rebuilt.
A number of tests have been updated and Fedora 30 has been added to the test suite so the unit tests can run on gcc 9.
Stop running unit tests on co6/7 since we appear to have ample unit test coverage.
This analysis never produced anything but false positives (var might be NULL) but took over a minute per test run and added 600MB to the test container.
ScalityS3 has not received any maintenance in years and is slow to start which is bad for testing. Replace it with minio which starts quickly and ships as a single executable or a tiny container.
Minio has stricter limits on allowable characters but should still provide enough coverage to show that our encoding is working correctly.
This commit also includes the upgrade to openssl 1.1.1 in the Ubuntu 18.04 container.
Update RHEL repos that have changed upstream. Remove PostgreSQL 9.3 since the RHEL6/7 packages have disappeared.
Remove PostgreSQL versions from U12 that are still getting minor updates so the container does not need to be rebuilt.
LZ4 is included for future development, but this seems like a good time to add it to the containers.
Test certificates were generated dynamically but there are advantages to using static certificates. For example, it possible to use the same certificate between container versions. Mostly, it is easier to document the certificates if they are not buried deep in the container code.
The new test certificates are initially intended to be used with the C unit tests but they will eventually be used for integration tests as well.
Two new certificates have been defined. See test/certificate/README.md for details.
The old dynamic certificates will be retained until they are replaced.
The standard npm packages on Ubuntu 18.04 suddenly required libssl1.0 which broke the pgbackrest package builds. Installing nodejs from deb.nodesource.com seems to work fine with standard libssl.
This package is required by ScalityS3 which is used for local S3 testing.
