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.
Remove embedded Perl from the distributed binary. This includes code, configure, Makefile, and packages. The distributed binary is now pure C.
Remove storagePathEnforceSet() from the C Storage object which allowed Perl to write outside of the storage base directory. Update mock/all and real/all integration tests to use storageLocal() where they were violating this rule.
Remove "c" option that allowed the remote to tell if it was being called from C or Perl.
Code to convert options to JSON for passing to Perl (perl/config.c) has been moved to LibC since it is still required for Perl integration tests.
Update build and installation instructions in the user guide.
Remove all Perl unit tests.
Remove obsolete Perl code. In particular this included all the Perl protocol code which required modifications to the Perl storage, manifest, and db objects that are still required for integration testing but only run locally. Any remaining Perl code is required for testing, documentation, or code generation.
Rename perlReq to binReq in define.yaml to indicate that the binary is required for a test. This had been the actual meaning for quite some time but the key was never renamed.
Three major changes were required to get this working:
1) Provide the path to pgbackrest in the build directory when running outside a container. Tests in a container will continue to install and run against /usr/bin/pgbackrest.
1) Set a per-test lock path so tests don't conflict on the default /tmp/pgbackrest path. Also set a per-test log-path while we are at it.
2) Use localhost instead of a custom host for TLS test connections. Tests in containers will continue to update /etc/hosts and use the custom host.
Add infrastructure and update harnessCfgLoad*() to get the correct exe and paths loaded for testing.
Since new tests are required to verify that running outside a container works, also rework the tests in Travis CI to provide coverage within a reasonable amount of time. Mainly, break up to doc tests by VM and run an abbreviated unit test suite on co6 and co7.
Scaling allows the starting values to be increased from the command-line without code changes.
Also suppress valgrind and assertions when running performance testing. Optimization is left at -O0 because we should not be depending on compiler optimizations to make our code performant, and it makes profiling more informative.
Sometimes it is useful to get at the internals of a module that is not being tested for coverage in order to provide coverage for another module that is being tested. The include directive allows this.
Update modules that had previously been added to coverage that only need to be included.
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.
Improve on 7794ab50 by including the build flag files directly into the Makefile as dependencies (even though they are not includes). This simplifies some of the rsync logic and allows make to do what it does best.
Also split build flag files into test, harness, and build to reduce rebuilds. Test flags are used to build test.c, harness flags are used to build the rest of the files in the test harness, and build flags are used for the files that are not directly involved in testing.
Many options that were set per test can instead be inferred from the types, i.e. container, c, expect, and individual.
Also finish renaming Perl unit tests with the -perl suffix.
This makes it easier to create objects and then copy them to another context when they are complete without having to worry about freeing them on error. Update List, StringList, and Buffer to allow moves. Update Ini and Storage to take advantage of moves.
Move command begin to C except when it must be called after another command in Perl (e.g. expire after backup). Command begin logs correctly for complex data types like hash and list. Specify which commands will log to file immediately and set the default log level for log messages that are common to all commands. File logging is initiated from C.
Buffering now takes the pending bytes on the socket into account (when present) rather than relying entirely on select(). In some instances the final bytes would not be flushed until the connection was closed.
The coverage report shows some code as never being run -- but that makes no sense because the tests pass. This may be due to trying to combine the C and Perl coverage reports and overwriting some runs.
Suppress for now with a plan to implement LCOV for the C unit tests.
* Add strCmp*() and strFirst*() to String.
* Add strLstSort() and strLstNewSplitSize() to StringList.
* Add strLstNewSplitZ() to StringList a update calls to strLstNewSplit() as needed.
* Add lstSort to List.
* Add strBeginsWith(), strEndsWith(), strEq(), and strBase().
* Enable compiler type checking for strNewFmt() and strCatFmt().
* Rename strNewSzN() to strNewN().
