I suggest the following change in the CMake install macros which will avoid excluding the MTR test .inc files. This fixes the (relevant) failing tests. I'll make a PR if this change is appropriate.

When building with -DWITH_WSREP=OFF, files required for MTR tests are excluded and several tests fail. This is cause by a recent commit 7b44d0ba which attempted to solve MDEV-23230.

Specifically, it is this specific change which causes the failure, right robinnew?

Perhaps there should be a CI build with WSREP/Galera disabled to catch this mistake sooner.

Agreed.

@dlenski Correct

Robin, I think you patch is right for the fault observed in gitlab, please do a PR.

Daniel, there might be different problem here. wsrep includes in sql/*.h (for non-wsrep files are):

sql/item_strfunc.h:#include "wsrep_api.h" - under a   #ifdef WITH_WSREP

sql/sql_class.h:#include "wsrep.h" - no def prot

sql/sql_class.h:#include "wsrep_on.h" - no def prot

sql/sql_class.h:#include "wsrep_client_service.h" - this and below under #ifdef WITH_WSREP

sql/sql_class.h:#include "wsrep_client_state.h"

sql/sql_class.h:#include "wsrep_mutex.h"

sql/sql_class.h:#include "wsrep_condition_variable.h"

So remove EXCL_WSREP parts of include/CMakeLists.txt for wsrep.h to be there.

and in sql/CMakeList -

SET(EXCL_WSREP "wsrep_[a-np-z]*.h")

maybe? to keep the wsrep_on.h, which happens to be the only wsrep_o*.h file.

On CI, seems to be getting more common so a build at least so probably soon.

Do you know of a test that links against the server headers?

Happy to take this as one or two PRs, whatever is easiest.

Thanks Daniel. PR created here: https://github.com/MariaDB/server/pull/2411

I have no issues with the change if it's right. I'm not sure what the MTR tests are, and why they need the wsrep/galera includes if wsrep isn't to be used. Shouldn't the tests instead be changed to not use need them when building without WSREP, similar to what was done to fix MDEV-25625?

Yes, agreed. If tests aren't actually using Galera/WSREP (and clearly if they're passing when it's not built… they're not ) then they shouldn't be including Galera/WSREP include files.

The test Robin tripped on Gitlab was missing include/wait_wsrep_ready.inc called from ./include/start_mysqld.inc (more widely used on many tests that restart the server) which has inbuilt tests which detects galera missing, which results in it being largely a no-op, but mtr can't tell that unless the file is there.

Both wsrep.h and wsrep_on.h contain no-op macros needed in the without wsrep case. so hence https://github.com/MariaDB/server/pull/2417 which adds the two files to the Devel package. Thanks dlenski

Okay. Just wanted to make sure the earlier removal of that one pattern from `INSTALL_MYSQL_TEST`s `EXCL_GALERA` was still correct.

Yes. Resulting wsrep files (including both PRs) is per https://github.com/MariaDB/server/pull/2417#issue-1521525371. Two or three files might be excess to absolute minimal requirements but its better than going too far.
