Bug#41860: Without Windows named pipe
The problem was that the patch for Bug#10374 broke named pipe
and shared memory transports on Windows due to a failure to
implement a dummy poll method for transports other than BSD
sockets. Another problem was that mysqltest lacked support
for named pipe and shared memory connections, which lead to
misleading test cases that were supposed run common queries
over both transports.
The solution is to properly implement, at the VIO layer, the
poll and is_connected methods. The is_connected method is
implemented for every suppported transport and the poll one
only where it makes sense. Furthermore, support for named pipe
and shared memory connections is added to mysqltest as to
enable testing of both transports using the test suite.
client/mysqltest.cc:
Add support for named pipe and shared memory connections.
include/violite.h:
Move private functions to vio/vio_priv.h
Add poll_read and is_connected methods.
mysql-test/t/named_pipe.test:
Run tests over a named pipe connection.
mysql-test/t/shm.test:
Run tests over a shared memory connection.
sql/item_func.cc:
Rename method.
sql/sql_class.cc:
Remove higher-level vio_is_connected implementation.
sql/sql_class.h:
Rename vio_is_connected to not conflict with the vio one.
Verify that there is a valid vio.
vio/vio.c:
Add poll_read and is_connected methods.
vio/vio_priv.h:
Add private functions.
vio/viosocket.c:
Implement the is_connected method for the various transports.
The problem is that the read and write methods of the shared
memory transport (protocol) didn't react to asynchronous close
events, which could lead to a lock up as the client would wait
(until time out) for a server response that will never come.
The solution is to also wait for close events while waiting
for I/O from or to the server.
mysql-test/r/shm.result:
Add test case result for Bug#33899
mysql-test/t/shm.test:
Add test case for Bug#33899
vio/viosocket.c:
Also wait for close events.
Improve test for shm on windows
mysql-test/include/windows.inc:
improve "skip message" and don't require a result file
mysql-test/r/shm.result:
Update result after adding more tests
mysql-test/t/shm-master.opt:
Add $MTR_BUILD_THREAD to get a unique shared memory base name
mysql-test/t/shm.test:
Run a bunch of more test to check shm
mysql-test/r/named_pipe.result:
New BitKeeper file ``mysql-test/r/named_pipe.result''
mysql-test/t/named_pipe-master.opt:
New BitKeeper file ``mysql-test/t/named_pipe-master.opt''
mysql-test/t/named_pipe.test:
New BitKeeper file ``mysql-test/t/named_pipe.test''
