WL#3951 - MyISAM: Additional Error Logs for Data Corruption When table corruption is detected, in addition to current error message provide following information: - list of threads (and queries) accessing a table; - thread_id of a thread that detected corruption; - source file name and line number where this corruption was detected; - optional extra information (string). mysql-test/r/myisam_crash_before_flush_keys.result: Adjusted a test case according to WL#3951. mysql-test/t/myisam_crash_before_flush_keys.test: Adjusted a test case according to WL#3951. storage/myisam/CMakeLists.txt: Added mi_extrafunc.h to myisam sources list. storage/myisam/Makefile.am: Added mi_extrafunc.h to myisam headers list. storage/myisam/ha_myisam.cc: Added _mi_report_crashed() function (reports additional information whenever table corruption is detected). storage/myisam/mi_extrafunc.h: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/mi_locking.c: For every call to mi_lock_database(F_[RD|WR|EXTRA_]LCK) - add current thread to the list of threads accessing this table. For every call to mi_lock_database(F_UNLCK) - remove current thread from the list of threads accessing this table. storage/myisam/mi_test1.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/mi_test2.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/mi_test3.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/myisam_ftdump.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/myisamchk.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/myisamdef.h: Extra elements are added to MI_INFO and MYISAM_SHARE structures. MI_INFO is extended with LIST element, that holds a pointer to THD object accessing a table. MYISAM_SHARE is extended with LIST (list of threads accessing a table). Whenever table is marked as crashed, call mi_report_crashed() macro to provide useful information. storage/myisam/myisamlog.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/myisampack.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/rt_test.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisam/sp_test.c: All standalone programs must define their version of _mi_report_crashed() by including mi_extrafunc.h. storage/myisammrg/ha_myisammrg.cc: For each unedrlying table initialize `in_use' variable.
