[Warning] InnoDB: Cannot change innodb_undo_tablespaces=0 because previous shutdown was not with innodb_fast_shutdown=0
because mariadbd *before this test* wasn't using innodb_fast_shutdown=0
Fix the bootstrap to use innodb_fast_shutdown=0 (and the bootstrap
creates a starting point for any test that uses a .cnf file)
followup for cac0fc97cc
also, remove redundant include/have_innodb.inc
Some fixes related to commit f838b2d799 and
Rows_log_event::do_apply_event() and Update_rows_log_event::do_exec_row()
for system-versioned tables were provided by Nikita Malyavin.
This was required by test versioning.rpl,trx_id,row.
MDEV-33582 Add more warnings to be able to better diagnose network issues
- Disabled "Semisync ack receiver got hangup" warning
- One could get this warning from semisync if running
mtr --mysqld=log-warnings=3 rpl.rpl_semi_sync_shutdown_await_ack
- Fixed result file for engines/funcs/rpl_get_lock.test
Warnings are added to net_server.cc when
global_system_variables.log_warnings >= 4.
When the above condition holds then:
- All communication errors from net_serv.cc is also written to the
error log.
- In case of a of not being able to read or write a packet, a more
detailed error is given.
Other things:
- Added detection of slaves that has hangup to Ack_receiver::run()
- vio_close() is now first marking the socket closed before closing it.
The reason for this is to ensure that the connection that gets a read
error can check if the reason was that the socket was closed.
- Add a new state to vio to be able to detect if vio is acive, shutdown or
closed. This is used to detect if socket is closed by another thread.
- Testing of the new warnings is done in rpl_get_lock.test
- Suppress some of the new warnings in mtr to allow one to run some of
the tests with -mysqld=--log-warnings=4. All test in the 'rpl' suite
can now be run with this option.
- Ensure that global.log_warnings are restored at test end in a way
that allows one to use mtr --mysqld=--log-warnings=4.

Let us suppress this timing-sensitive warning globally.
We added it in commit d34479dc66 (MDEV-33053)
so that in case InnoDB hangs due to running out of buffer pool, there
would be a warning about it. On a heavily loaded system that is running
with a small buffer pool, these warnings may be occasionally issued
while page writes are in progress.
The directio(3C) function on Solaris is supported on NFS and UFS
while the majority of users should be on ZFS, which is a copy-on-write
file system that implements transparent compression and therefore
cannot support unbuffered I/O.
Let us remove the call to directio() and simply treat
innodb_flush_method=O_DIRECT in the same way as the previous
default value innodb_flush_method=fsync on Solaris. Also, let us
remove some dead code around calls to os_file_set_nocache() on
platforms where fcntl(2) is not usable with O_DIRECT.
On IBM AIX, O_DIRECT is not documented for fcntl(2), only for open(2).
