…umbers with `+` sign Fixed parser inconsistency where CHANGE MASTER TO master_heartbeat_period rejected numeric values with an explicit '+' sign, while other parameters like master_connect_retry accepted them. The issue was in sql/sql_yacc.yy where master_heartbeat_period used NUM_literal (which doesn't accept '+'), while other parameters used ulong_num (which includes opt_plus). Solution: Added opt_plus before NUM_literal in the master_heartbeat_period grammar rule, making it consistent with other numeric parameters. Added test case to verify: - master_heartbeat_period=+60 now works (was broken) - master_heartbeat_period=60 still works (backward compatible) - Consistent behavior across all CHANGE MASTER TO numeric parameters All new code of the whole pull request, including one or several files that are either new files or modified ones, are contributed under the BSD-new license.

I’m back from Weekend Wednesday!
Thanks for including a test as well!
Although I don’t like how the older tests are named mdev_ABCD – very undescriptive.
Though for this topic, I suggest including the master_heartbeat_period=+60 test under the existing CHANGE MASTER test, which would be mysql-test/suite/rpl/t/rpl_heartbeat_basic.test by convention (if not rpl.rpl_heartbeat and it seems to have have their purposes mixed together).
master_connect_retry=+60 would belong to the corresponding CHANGE MASTER test… if there is one.
It and other fields are not the focus, anyhow.
(This is the status quo… I’d actually prefer gathering ALL format tests together in one script.)
As for the slave_net_timeout warning on amd64-debian-12-debug-embedded – It might be because the test needs --source include/not_embedded.inc, which in the rpl suite is normally practically covered by rpl_init.inc and co..
(We still can’t just get rid of Embedded builds… oh well.)

Description
Fixed parser inconsistency where CHANGE MASTER TO master_heartbeat_period rejected numeric values with an explicit '+' sign, while other parameters like master_connect_retry accepted them.
The issue was in sql/sql_yacc.yy where master_heartbeat_period used NUM_literal (which doesn't accept '+'), while other parameters used ulong_num (which includes opt_plus).
Solution: Added opt_plus before NUM_literal in the master_heartbeat_period grammar rule, making it consistent with other numeric parameters.
How can this PR be tested?
Execute the
mdev_38454.testinrpltest suite in mysql-test-run.Basing the PR against the correct MariaDB version
Backward compatibility
This is a bug fix which allows "+" sign for "master_heartbeat_period". It is compatible with previous versions.
