MWL#192: Non-blocking client API for libmysqlclient. All client functions that can block on I/O have alternate _start() and _cont() versions that do not block but return control back to the application, which can then issue I/O wait in its own fashion and later call back into the library to continue the operation. Works behind the scenes by spawning a co-routine/fiber to run the blocking operation and suspend it while waiting for I/O. This co-routine/fiber use is invisible to applications. For i368/x86_64 on GCC, uses very fast assembler co-routine support. On Windows uses native Win32 Fibers. Falls back to POSIX ucontext on other platforms. Assembler routines for more platforms are relatively easy to add by extending mysys/my_context.c, eg. similar to the Lua lcoco library. For testing, mysqltest and mysql_client_test are extended with the option --non-blocking-api. This causes the programs to use the non-blocking API for database access. mysql-test-run.pl has a similar option --non-blocking-api that uses this, as well as additional testcases. An example program tests/async_queries.c is included that uses the new non-blocking API with libevent to show how, in a single-threaded program, to issue many queries in parallel against a database. client/async_example.c: Fix const warning ****** Fix bug with wrong timeout value for poll(). include/Makefile.am: Fix missing include for `make dist` include/mysql.h: Add prototypes for all non-blocking API calls. include/mysql.h.pp: Add prototypes for all non-blocking API calls. mysys/my_context.c: Fix type warning for makecontext() function pointer argument. sql-common/mysql_async.c: Fix crashes in the non-blocking API for functions that can take MYSQL argument that is NULL. tests/Makefile.am: Add header file to `make dist` tests/mysql_client_test.c: Replace blocking calls with wrappers around the non-blocking calls, used in mysql_client_test to test the new non-blocking API. tests/nonblock-wrappers.h: Replace blocking calls with wrappers around the non-blocking calls, used in mysql_client_test to test the new non-blocking API. 2011-09-20 12:49:25 +02:00			`SET @old_general_log= @@global.general_log;`
