Set log-level-file=off when more that one test will run. In this case is it impossible to see the logs anyway since they will be automatically cleaned up after the test. This improves performance pretty dramatically since trace-level logging is expensive. If a singe integration test is run then log-level-file is trace by default but can be changed with the --log-level-test-file option.
Reduce buffer-size to 64k to save memory during testing and allow more processes to run in parallel.
Update log replacement rules so that these options can change without affecting expect logs.
This user was created before we tested in containers to ensure isolation between the pg and repo hosts which were then just directories. The downside is that this resulted in a lot of sudos to set the pgbackrest user and to remove files which did not belong to the main test user.
Containers provide isolation without needing separate users so we can now safely remove the pgbackrest user. This allows us to remove most sudos, except where they are explicitly needed in tests.
While we're at it, remove the code that installed the Perl C library (which also required sudo) and simply add the build path to @INC instead.
No new Perl code is being developed, so these tools are just taking up time and making migrations to newer platforms harder. There are only a few Perl tests remaining with full coverage so the coverage tool does not warn of loss of coverage in most cases.
Remove both tools and associated libraries.
Maintaining the storage layer/drivers in two languages is burdensome. Since the integration tests require the Perl storage layer/drivers we'll need them even after the core code is migrated to C. Create an interface layer so the Perl code can be removed and new storage drivers/features introduced without adding Perl equivalents.
The goal is to move the integration tests to C so this interface will eventually be removed. That being the case, the interface was designed for maximum compatibility to ease the transition. The result looks a bit hacky but we'll improve it as needed until it can be retired.
C or Perl coverage tests can now be run on any VM provided a recent enough version of Devel::Cover or lcov is available.
For now, leave u18 as the only VM to run coverage tests due to some issues with older versions of lcov.
Running coverage testing on multiple distros takes time but doesn't add significant value. Also ensure that the distro designated to run coverage tests is one of the default test distros.
Refactor storage layer to allow for new repository filesystems using drivers. (Reviewed by Cynthia Shang.)
Refactor IO layer to allow for new compression formats, checksum types, and other capabilities using filters. (Reviewed by Cynthia Shang.)
* Full coverage is verified when specified.
* Modules marked with partial coverage will error if they are actually fully covered.
* Simplified test representation is DefineTest.
* Added new representation for queries in DefineTest and added API functions.
* Update modules using DefineTest to use new API.
* Allow logging to be suppressed via logDisable() and logEnable().
* Added more flexibility in initializing and cleaning up after modules and tests.
* testResult() suppresses logging and reports exceptions.
* testException() allows messages to be matched with regular expressions.
* Refactor name/locations of common modules that setup test environments.
