Running valgrind and backtrace together has been causing tests to timeout in CI, mostly likely due to limited resources. This has not been a problem in normal development environments.
Since it is still important to run backtraces for debugging, split the u22 test that was doing all this work to run coverage and backtrace together and valgrind-only as a separate test. As a bonus these tests run faster separately and since they run in parallel the total execution time is faster.
When this code was migrated to C the unit tests were not included because there were more important priorities at the time.
This also requires some adjustments to coverage because of the new code location.
All unit and performance tests are now built by the C harness.
Remove all unit/performance test build code from Perl.
Remove code from C harness that is no longer used. This code was included so the C harness could be run separately, but that is no longer needed with this full integration.
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).
Build pgbackrest binary and auto-generated code automatically.
Remove --module option and allow modules to run by parameter. This is less verbose and multiple modules can be run at a time.
Allow filtering of modules. Multiple tests can be passed as parameters and if the module ends in / it will be used as a prefix filter. For example, common/ will run all the common modules.
If a test errors the remaining tests will still run but the test process will eventually exit with an error.
CI tests are included but unit tests remain on the development branch.
With these changes all unit tests run except those that specify the define (e.g. common/assert-off) or containerReq (e.g. protocol/protocol) keywords.
Building the C test harness has been simplified:
meson -Dwerror=true -Dfatal-errors=true -Dbuildtype=debug test/build/none pgbackrest
ninja -C test/build/none test/src/test-pgbackrest
To run all modules:
test/build/none/test/src/test-pgbackrest test
Just the common/error module:
test/build/none/test/src/test-pgbackrest test common/error
All info modules:
test/build/none/test/src/test-pgbackrest test info/
Having the test harness in C will allow us to remove duplicated Perl code and test on systems where Perl support is not present.
Custom harnesses and shims are currently not implemented, which means only the following tests in the common module will run: error, stack-trace, type-convert, assert-on, mem-context, time, encode, type-object, type-string, type-list, type-buffer, type-variant, reg-exp, log.
The experimental test harness is being committed with partial functionality so it can be used in Windows development. The remaining features will follow as needed.
