* MDEV-23238 - remove async client from server code.Vladislav Vaintroub2020-09-011-761/+0
| | | | | | | It is already in libmariadb, and server (also that client in server) does not need it. It does not work in embedded either since it relies on non-blocking sockets

| | * mysql_client_test_nonblock fails when compiled with clangVicențiu Ciorbaru2017-03-081-1/+2
| | | | | | | | | | | | | | | | | | | | | mysql_client uses some inline assembly code to switch thread stacks. This works, however tools that perform backtrace get confused to fix this we write a specific constant to signify bottom of stack. This constant is needed when compiling with CLang as well.

| | * Fix compiler check for stack unwind hintKristian Nielsen2016-06-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The check inserts a DWARF directive to tell stack unwinding that the bottom of the (co-routine) stack has been reached. Without this, stack traces may attempt to continue past the bottom of the stack. The GCC version check was incorrect, and failed to trigger for GCC version 5.[0123].

| * MDEV-4601 : Allow MariaDB to be build without non-blocking client.Vladislav Vaintroub2013-06-151-0/+34
| | | | | | | | | | Non-blocking client currently can be build on Windows, GCC on i386 and x64, or any OS wth ucontext.h header. Prior to this patch, build failed if neither of these conditions is true. Fix to avoid compiler errors in these case - non-blocking API would not be useful on , but otherwise everything will work as before.

| * Fix crashes on 32-bit async client lib when -fomit-frame-pointerunknown2012-10-311-5/+16
| | | | | | | | | | | | | | | | | | | | - Ensure asm parameters are in registers, so we do not de-reference from bogus stack pointer. - Make return address undefined in DWARF unwind info in my_context_spawn, so DWARF-based unwinders will know this is the end of the call stack (same as the amd64 fix for the similar issue).

* MWL#192: non-blocking client API, after-review fixes.unknown2012-01-061-87/+35
| | | | | | | | | | | Main change is that non-blocking operation is now an option that must be explicitly enabled with mysql_option(mysql, MYSQL_OPT_NONBLOCK, ...) before any non-blocing operation can be used. Also the CLIENT_REMEMBER_OPTIONS flag is now always enabled and thus effectively ignored (it was not really useful anyway, and this simplifies things when non-blocking mysql_real_connect() fails).
* MWL#192: Non-blocking client API for libmysqlclient.unknown2011-09-201-0/+749
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.
