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().
