Refactor the code to allow a dynamic number of indexes for indexed options, e.g. pg-path. Our reliance on getopt_long() still limits the number of indexes we can have per group, but once this limitation is removed the rest of the code should be happy with dynamic numbers of indexes (with a reasonable maximum).
Add an option to set a default in each group. This was previously handled by the host-id option but now there is a specific option for each group, pg and repo. These remain internal until they can be fully tested with multi-repo support. They are fully tested for internal usage.
Remove the ConfigDefineOption enum and use the ConfigOption enum instead. They are now equal since the indexed options (e.g. cfgOptRepoHost2) have been removed from ConfigOption.
Remove the config/config test module and add required tests to the config/parse test module. Parsing is now the only way to load a config so this removes some redundancy.
Split new internal config structures and functions into a new header file, config.intern.h. More functions will need to be moved over from config.h but that will need to be done in a future commit to reduce churn.
Add repoIdx to repoIsLocal() and storageRepo*(). Multi-repository support requires that repo locality and storage be accessible by index. This allows, for example, multiple repos to be iterated in a loop. This could be done in a separate commit but doesn't seem worth it since the code is related.
Remove the type parameter from storageRepoGet(). This parameter existed solely to provide coverage for the case where the storage type was invalid. A better pattern is to check that the type is S3 once all other types have been ruled out.
This has always been equivalent to the ConfigCommand enum so it just adds complexity.
It was created for symmetry with ConfigDefineOption, which will also be removed soon.
The primary source for project info is now src/version.h.
The pgBackRestDoc::ProjectInfo module loads the project info from src/version.h at runtime so there is no need to update it.
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.
The tests and documentation have been using the core storage layer but soon that will depend entirely on the C library, creating a bootstrap problem (i.e. the storage layer will be needed to build the C library).
Create a simplified Posix storage layer to be used by documentation and the parts of the test code that build and execute the actual tests. The actual tests will still use the core storage driver so they can interact with any type of storage.
