in e5b1ae5554, a new option named
"debug_version_for_testing" is introduced to override the version so
we can test version check.
in crimson, we have two families of shared functions.
- one of them is used by alien store. they are compiled with
-DWITH_SEASTAR and -DWITH_ALIEN, to enable the shim code between
seastar and POSIX thread.
- another is used by crimson in general. where no lock is allowed.
currently, we use the "crimson" and "ceph" namespace to differentiate
these two families of functions, so they can colocate in the same
executable without violating the ODR. see src/include/common_fwd.h for
more details.
the functions defined in src/common/version.cc are also shared by
alien store and crimson code. and because we have different
implementations of `CephContext` in crimson and in classic OSD (i.e.
alienstore), we have to have different implementations of this function
as well, if we follow the same approach. but since these functions are
very simple and are non-blocking, there is not much value in
differentiating them, it is better to inject the test settings using
environment variable instead of using ceph option subsystem.
in this change, "ceph_debug_version_for_testing" environment variable is
checked instead, so that crimson and alienstore can share the same
compilation unit of version.cc. and "debug_version_for_testing" option
is removed.
