| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (variables_debug fails) The problem was that "SET GLOBAL debug" could cause a crash on Solaris. The crash happened if the server failed to open the trace file given in the "SET GLOBAL debug" statement. This caused an error message to be printed to stderr containing the process name. However, printing to stderr crashed the server since the pointer to the process name had not been initialized. This patch fixes the problem by initializing the process name properly when doing "SET GLOBAL debug". No test case added as this bug was repeatable with existing test coverage in variables_debug.test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When re-setting (SET GLOBAL debug='') the GLOBAL debug settings the server was not freeing the data elements from the top (initial) frame before setting them to 0 without freeing the underlying memory. As these are global settings there's a chance that something is there already. Fixed by : 1. making sure the allocated data are cleaned up before re-setting them while parsing a debug string 2. making sure the stuff allocated in the global settings is freed on shutdown.
| * | | Bug #46165 server crash in dbugJon Olav Hauglid2010-09-281-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This crash occured if the same debug trace file was closed twice, leading to the same memory being free'd twice. This could occur if the "debug" server system variable refered to the same trace file in both global and session scope. Example of an order of events that would lead to a crash: 1) Enable debug tracing to a trace file (global scope) 2) Enable debug tracing to the same trace file (session scope) 3) Reset debug settings (global scope) 4) Reset debug settings (session scope) This caused a crash because the trace file was, by mistake, closed in 3), leading to the same memory being free'd twice when the file was closed again in 4). Internally, the debug settings are stored in a stack, with session settings (if any) on top and the global settings below. Each connection has its own stack. When a set of settings is changed, it must be determined if its debug trace file is to be closed. Before, this was done by only checking below on the settings stack. So if the global settings were changed, an existing debug trace file reference in session settings would be missed. This caused the file to be closed even if it was in use, leading to a crash later when it was closed again. This patch fixes the problem by preventing the trace file from being shared between global and session settings. If session debug settings are set without specifying a new trace file, stderr is used for output. This is a change in behaviour and should be reflected in the documentation. Test case added to variables.test.

Additional tests. mysql-test/t/merge_debug.test: Test of error handling when reopening MERGE tables. mysql-test/t/udf_query_cache.test: Added missing flush status mysys/my_getopt.c: Removed not used variable mysys/my_symlink2.c: Changed (null) to (NULL) to make it easier to find NULL arguments to DBUG_PRINT() functions. (On linux, NULL to sprintf is printed 'null') mysys/thr_lock.c: Added priority of locks to avoid crashes with MERGE tables. Added thr_lock_merge() to allow one to merge two results of thr_lock(). - This is needed for MyISAM as all locked table must share the same status. If not, you will not see newly inserted rows in other instances of the table. If calling thr_unlock() with THR_UNLOCK_UPDATE_STATUS, call update_status() and restore_status() for the locks. This is needed in some rare cases where we call thr_unlock() followed by thr_lock() without calling external_unlock/external_lock in between. Simplify loop in thr_multi_lock(). Added 'start_trans', which is called at end of thr_multi_lock() when all locks are taken. - This was needed by Aria to ensure that transaction is started when we got all locks, not at get_status(). Without this, some rows could not be visible when we lock two tables at the same time, causing REPLACE using two tables to fail unexpectedly. sql/handler.cc: Add an assert() in handler::print_error() for "impossible errors" (like table is crashed) when --debug-assert-if-crashed-table is used. sql/lock.cc: Simplify mysql_lock_tables() code if get_lock_data() returns 0 locks. Added new parameter to thr_multi_unlock() In mysql_unlock_read_tables(), call first externa_unlock(), then thr_multi_unlock(); This is same order as we do in mysql_unlock_tables(). Don't abort locks in mysql_lock_abort() for merged tables when a MERGE table is deleted; Would cause a spin lock. Added call to thr_merge_locks() in mysql_lock_merge() to ensure consistency in thr_locks(). - New locks of same type and table is stored after the old lock to ensure that we get the status from the original lock. sql/mysql_priv.h: Added debug_assert_if_crashed_table sql/mysqld.cc: Added --debug-assert-if-crashed-table sql/parse_file.cc: Don't print '(null)' in DBUG_PRINT of no dir given sql/set_var.cc: Increase default size of buffer for @debug variable. sql/sql_base.cc: In case of error from reopen_table() in reopen_tables(), call unlock_open_table() and restart loop. - This fixed bug when we twice deleted same table from open_cache. Don't take name lock for already name locked table in open_unireg_entry(). - Fixed bug when doing repair in reopen_table(). - In detach_merge_children(), always detach if 'clear_refs' is given. We can't trust parent->children_attached as this function can be called twice, first time with clear_refs set to 0. sql/sql_class.cc: Changed printing of (null) to "" in set_thd_proc_info() sql/sql_parse.cc: Added DBUG sql/sql_trigger.cc: Don't call unlink_open_table() if reopen_table() fails as the table may already be freed. storage/maria/ma_bitmap.c: Fixed DBUG_ASSERT() in allocate_tail() storage/maria/ma_blockrec.c: Fixed wrong calculation of row length for very small rows in undo_row_update(). - Fixes ASSERT() when doing undo. storage/maria/ma_blockrec.h: Added _ma_block_start_trans() and _ma_block_start_trans_no_versioning() storage/maria/ma_locking.c: Call _ma_update_status_with_lock() when releasing write locks. - Fixes potential problem with updating status without the proper lock. storage/maria/ma_open.c: Changed to use start_trans() instead of get_status() to ensure that we see all rows in all locked tables when we got the locks. - Fixed 'not found row' bug in REPLACE with Aria tables. storage/maria/ma_state.c: Added _ma_update_status_with_lock() and _ma_block_start_trans(). This is to ensure that we see all rows in all locked tables when we got the locks. storage/maria/ma_state.h: Added _ma_update_status_with_lock() storage/maria/ma_write.c: More DBUG_PRINT storage/myisam/mi_check.c: Fixed error message storage/myisam/mi_extra.c: Added HA_EXTRA_DETACH_CHILD: - Detach MyISAM table to not be part of MERGE table (remove flag & lock priority). storage/myisam/mi_locking.c: Call mi_update_status_with_lock() when releasing write locks. - Fixes potential problem with updating status without the proper lock. Change to use new HA_OPEN_MERGE_TABLE flag to test if MERGE table. Added mi_fix_status(), called by thr_merge(). storage/myisam/mi_open.c: Added marker if part of MERGE table. Call mi_fix_status() in thr_lock() for transactional tables. storage/myisam/myisamdef.h: Change my_once_flag to uint, as it stored different values than just 0/1 Added 'open_flag' to store state given to mi_open() storage/myisammrg/ha_myisammrg.cc: Add THR_LOCK_MERGE_PRIV to THR_LOCK_DATA to get MERGE locks sorted after other types of locks. storage/myisammrg/myrg_locking.c: Remove windows specific code. storage/myisammrg/myrg_open.c: Use HA_OPEN_MERGE_TABLE to mi_open(). Set HA_OPEN_MERGE_TABLE for linked MyISAM tables. storage/xtradb/buf/buf0buf.c: Fixed compiler warning storage/xtradb/buf/buf0lru.c: Initialize variable that could be used not initialized.

Instead, give a nice summary report at the end of the failures. Fix code to make 100% sure no failures will go undetected. Revert earlier wrong change. Fix race with port allocation semaphore file permissions. Adjust testsuite to copy with new PBXT engine now in the tree. The PBXT engine causes an extra table to appear in the INFORMATION_SCHEMA. This causes different output for a few test cases. dbug/dbug.c: If DbugParse() is called multiple times, the stack->keywords for the top stack frame could be overwritten without being freed, causing a memory leak reported by Valgrind. include/my_global.h: Add useful macro for different values when Valgrind (HAVE_purify) and not. mysql-test/extra/rpl_tests/rpl_auto_increment.test: Omit pbxt variables from show variables output. mysql-test/include/have_pbxt.inc: Add facility to disable test if PBXT engine is not available. mysql-test/lib/mtr_report.pm: Give a nice summary report at the end of tests of any warnings seen in logs during server shutdowns. mysql-test/lib/mtr_unique.pm: Move chmod 777 to greatly reduce the risk of leaving the port semaphore file unaccessible bu other users. mysql-test/mysql-test-run.pl: Don't abort in case of warnings detected, instead give a nice summary report. Fix code to make 100% sure no failures will go undetected. Revert earlier wrong change when master disconnects early. mysql-test/r/information_schema.result: Omit PBXT INFORMATION_SCHEMA table from output. Move part of test to information_schema_all_engines. mysql-test/r/information_schema_all_engines.result: New file for information_schema tests that depend on which engines are available. mysql-test/r/information_schema_db.result: Move part of test to information_schema_all_engines. mysql-test/r/innodb-autoinc.result: Omit pbxt variables from show variables output. mysql-test/r/mysqlshow.result: Move part of test to information_schema_all_engines. mysql-test/suite/rpl/r/rpl_auto_increment.result: Omit pbxt variables from show variables output. mysql-test/t/information_schema.test: Omit PBXT INFORMATION_SCHEMA table from output.

Add suppression for problem with inet_ntoa(). sql/mysqld.cc: Fix missing DBUG_RETURN. Fix uninitialised thd->connect_utime, likely introduced by pool_of_threads. sql/set_var.cc: Fix one-byte buffer overflow in several places. Fix unsafe use of String::c_ptr() of stack-allocated String buffer. sql/sql_select.cc: Silence valgrind warning due to GCC bug. sql/sql_string.h: Document potential problem with String::c_ptr() and String() constructor with caller-supplied buffer. storage/archive/azio.c: Silence Valgrind false warning for libz.
