lcov does not seem to be very well maintained and is often not compatible with the version of gcc it ships with until a few months after a new distro is released. In any case, lcov is that not useful for us because it generates reports on all coverage while we are mainly interested in missing coverage during development.
Instead use the JSON output generated by gcov to generate our minimal coverage report and metrics for the documentation.
There are some slight differences in the metrics. The difference in the common module was due to a bug in the old code -- build/common was being added into common as well as being reported separately. The source of the two additional branches in the backup module is unknown but almost certainly down to how exclusions are processed with regular expressions. Since there is additional coverage rather than coverage missing this seems fine.
Since this was pretty much a rewrite it was also a good time to migrate to C.
The code is not completely reflowed yet so there are some cases that uncrustify will not catch. The formatting will be improved over time.
Some block of code require special formatting so have been surrounded with the {uncrustify-off}/{uncrustify-on} markers. These exceptions should be kept to a minimum.
Add --code-format (to reformat code) and --code-format-check (to check formatting) to test.pl.
Add a CI test that will check code formatting. Code must be correctly formatted before it can be merge to integration.
Add documentation to the coding standards for code formatting.
Add tzdata package so timezone tests in command/restore work correctly.
Mark default git path as safe. This is a security fix that is not applicable in this environment, but must be set.
Also remove package cleanup, which is inconvenient when new packages need to be installed. It makes sense for containers that will be downloaded from Dockerhub but not so much for a locally-maintained container.
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.
Meson is a new build system that offers simpler syntax and superior performance to autoconf/make. In addition, Windows is supported natively.
The Meson build appears complete, but currently is used only for auto-generation of code and the host build of pgbackrest. Some container upgrades will be required before Meson can be used for container builds.
Also patch the Debian package to force autoconf/make rather than Meson.
This is a bit of legacy from the current Vagrant environment used to do the release, but since it is not as easy to change the user in Vagrant, just make the Docker environment conform.
This allows documentation to be built in a Vagrant environment (or any environment with the same user name) and to be deployed in a Docker environment.
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.
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.
