* MDEV-22950 followupVladislav Vaintroub2020-06-251-1/+4
| | | | | | | | | Deadlock in DbugParse, on Linux. In 10.1, DBUG recursive mutex was improperly implemented. CODE_STATE::locked counter was never updated. Copy the code around LockMutex/UnlockMutex from 10.2
* mtr: use env for perlDaniel Black2020-06-232-2/+2
| | | | | | | | On FreeBSD, perl isn't in /usr/bin, its in /usr/local/bin or elsewhere in the path. Like storage/{maria/unittest/,}ma_test_* , we use /usr/bin/env to find perl and run it.
* MDEV-22950 : fix race condition in dbugVladislav Vaintroub2020-06-201-2/+2

* try to fix data races in DBUGEugene Kosov2019-11-281-2/+40
| | | | | init_settings.keywords and it's pointee are shared data. Protect them with mutex too.
* cleanup DBUGEugene Kosov2019-11-211-39/+28
| | | | | | | | | | | DbugParse(): removed mutex lock/unlock which should protect file writes only. And no file writes happen in this function. DbugFlush(): move mutex_unlock out of this method because fflush() doesn't need any locking. Slow stuff like mutex lock/unlock and accessing errno (TLS) is moved to a more narrow scope.

* | dbug: correct trace for DBUG_RETURN(func()); -- gcc onlySergei Golubchik2015-11-161-3/+7
| | | | | | | | | | | | | | | | | | | | | | when func1 calls func2 from DBUG_RETURN, dbug shows the trace as | > func1 | < func1 | > func2 | < func2 because DBUG_LEAVE happens before func2(). Change that to invoke DBUG_LEAVE when the local variable goes out of scope. This uses gcc specific __attribute__((cleanup)).

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.

| * | | Bug#12779790 COMPILATION FAILS OS X 10.7 - IMPLICIT DECLARATION OFJon Olav Hauglid2011-07-213-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FUNCTION 'PTHREAD_INIT' The problem was that compilation would fail with a warning: Implicit declaration of function 'pthread_init' if MySQL was compiled on OS X 10.7 (Lion). The reason was that pthread_init() is now part of an internal OS X pthread library so it was found by CMake. This patch fixes the problem by removing HAVE_PTHREAD_INIT and related code. pthread_init() was specific to MIT-pthreads which has not been supported since 4.1 and was therefore no longer relevant. No test case added.
| * | | Bug#12727287: Maintainer mode compilation fails with gcc 4.6Davi Arnaut2011-07-071-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 4.6 has new -Wunused-but-set-variable flag, which is enabled by -Wall, that causes GCC to emit a warning whenever a local variable is assigned to, but otherwise unused (aside from its declaration). Since the maintainer mode uses -Wall and -Werror, source code which triggers these warnings will be rejected. That is, these warnings become hard errors. The solution is to fix the code which triggers these specific warnings. In most of the cases, this is a welcome cleanup as code which triggers this warning is probably dead anyway. dbug/dbug.c: Unused but set. libmysqld/lib_sql.cc: Length is not necessary as the converted error message is always null-terminated. sql/item_func.cc: Make get_var_with_binlog private to this compilation unit. If a error was raised, do not attempt to evaluate the user variable as the statement execution will be interrupted anyway. sql/mysqld.cc: Use a void expression to silence the warning. Avoids the use of macros that would make the code more unreadable than it already is. sql/protocol.cc: Length is not necessary as the converted error message is always null-terminated. Remove unnecessary casts and assignment. sql/sql_class.h: Function is only used in a single compilation unit. sql/sql_load.cc: Only use the variable outside of EMBEDDED_LIBRARY. storage/innobase/btr/btr0cur.c: Do not retrieve field, only the record length is being used. storage/perfschema/pfs.cc: Use a void expression to silence the warning. tests/mysql_client_test.c: Unused but set. unittest/mysys/lf-t.c: Unused but set.

| * | | Bug#473914: mysql_client_test fail with in debug compilaton on windows x64Vladislav Vaintroub2010-12-061-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reason: inconsistent compilation, federatedx is compiled without SAFEMALLOC flag, while anything else is compiled with SAFEMALLOC. As a consequence, my_hash_init used inside federatedx initialization does not provide correct caller info parameters (file, line) , so they are initialized with whatever is on stack. When info about allocated memory is output in COM_DEBUG command, the server crashes trying to output string starting at 0xcccccccccccccccc. The fix is to remove SAFEMALLOC preprocessor flags from every CMakeLists.txt, except the top-level one. Also, SAFEMALLOC is not defined by default now, instead there is WITH_DEBUG_FULL CMake option which adds -DSAFEMALLOC to C and C++ flags in debug compilation. This option is off by default, because 1) Debug C runtime already has heap debugging builtin with overwrite and leak detection 2)safemalloc considerably slows down the tests. Note also that - SAFEMALLOC is gone in MySQL5.5 - On Windows, heap related overflows can also be found using free pageheap utility (that is also part of application verifier). This is even more efficient if there are no other layers on top of Windows heap allocator, e.g it is most efficient with release version.
