| * Added name to MEM_ROOT for esier debuggingMonty2018-02-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This will make it easier to how memory allocation is done when debugging with either DBUG or gdb. Will especially help when debugging stored procedures Main change is a name argument as second argument to init_alloc_root() init_sql_alloc() Other things: - Added DBUG_ENTER/EXIT to some Virtual_tmp_table functions

| | | | | | | | | | | | | | | | | | | | | | - Fix win64 pointer truncation warnings (usually coming from misusing 0x%lx and long cast in DBUG) - Also fix printf-format warnings Make the above mentioned warnings fatal. - fix pthread_join on Windows to set return value.
* | Fix that end_bulk_insert() doesn't write to to-be-deleted filesMonty2017-05-171-14/+51
|/ | | | | | | | | | | | | | This affected mainly MyISAM and Aria engines. Also fixed that end_bulk_insert() detects errors from internal mi_end_bulk_insert() and ma_end_bulk_insert() - delete_tree() and delete_tree_element() now has an extra argument that marks if future calls to tree->free should be ignored. - tree->free changed to function returning int, to be able to signal errors. - Restored deleting flag in MyISAM that was accidently disabled in mi_extra(PREPARE_FOR_DROP)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UNIQUE::~UNIQUE | SQL/UNIQUES.CC:355 Analysis ======== Enabling the sort_buffer_size with a large value can cause operations utilizing the sort buffer like DELETE as mentioned in the bug report to fail. 5.5 and 5.6 versions reports OOM error while in 5.7+, the server crashes. While initializing the mem_root for the sort buffer tree, the block size for the mem_root is determined from the 'sort_buffer_size' value. This unsigned long value is typecasted to unsigned int, hence it becomes zero. Further block_size computation while initializing the mem_root results in a very large block_size value. Hence while trying to allocate a block during the DELETE operation, an OOM error is reported. In case of 5.7+, the PFS instrumentation for memory allocation, overshoots the unsigned value and allocates a block of just one byte. While trying to free the block of the mem_root, the original block_size is used. This triggers the crash since the server tries to free unallocated memory. Fix: ==== In order to restrict usage of such unreasonable sort_buffer_size, the typecast of block size to 'unsigned int' is removed and hence reports OOM error across all versions for sizes exceeding unsigned int range.

| | * | Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabledDavi Arnaut2010-07-081-2/+2
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Essentially, the problem is that safemalloc is excruciatingly slow as it checks all allocated blocks for overrun at each memory management primitive, yielding a almost exponential slowdown for the memory management functions (malloc, realloc, free). The overrun check basically consists of verifying some bytes of a block for certain magic keys, which catches some simple forms of overrun. Another minor problem is violation of aliasing rules and that its own internal list of blocks is prone to corruption. Another issue with safemalloc is rather the maintenance cost as the tool has a significant impact on the server code. Given the magnitude of memory debuggers available nowadays, especially those that are provided with the platform malloc implementation, maintenance of a in-house and largely obsolete memory debugger becomes a burden that is not worth the effort due to its slowness and lack of support for detecting more common forms of heap corruption. Since there are third-party tools that can provide the same functionality at a lower or comparable performance cost, the solution is to simply remove safemalloc. Third-party tools can provide the same functionality at a lower or comparable performance cost. The removal of safemalloc also allows a simplification of the malloc wrappers, removing quite a bit of kludge: redefinition of my_malloc, my_free and the removal of the unused second argument of my_free. Since free() always check whether the supplied pointer is null, redudant checks are also removed. Also, this patch adds unit testing for my_malloc and moves my_realloc implementation into the same file as the other memory allocation primitives.

Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updating data in HEAP table with BTREE index results in wrong index_length counter value, which keeps growing after each update. When inserting new record into tree counter is incremented by: sizeof(TREE_ELEMENT) + key_size + tree->size_of_element But when deleting element from tree it doesn't decrement counter by key_size: sizeof(TREE_ELEMENT) + tree->size_of_element This fix makes accurate allocated memory counter for tree. That is decrease counter by key_size when deleting tree element.

The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC. Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc(). There are plenty of new asserts to ensure that for a debug server the counting is correct. Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS. - The later is there mainly to show how query is progressing. The following changes in interfaces was needed to get this to work: - init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root() - my_init_dynamic_array() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - Added flag for hash_init() so that one can mark hash table to be thread specific. - Added flags to init_tree() so that one can mark tree to be thread specific. - Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG. - Added flag to Warning_info::Warning_info() if the structure should be fully initialized. - String elements can now be marked as thread specific. - Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC. - Changed type of myf from int to ulong, as this is always a set of bit flags. Other things: - Removed calls to net_end() and thd->cleanup() as these are now done in ~THD() - We now also show EXAMINED_ROWS in SHOW PROCESSLIST - Added new variable 'memory_used' - Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory. - Removed calls to the obsoleted function init_dynamic_array() - Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...) client/completion_hash.cc: Updated call to init_alloc_root() client/mysql.cc: Updated call to init_alloc_root() client/mysqlbinlog.cc: init_dynamic_array() -> my_init_dynamic_array() Updated call to init_alloc_root() client/mysqlcheck.c: Updated call to my_init_dynamic_array() client/mysqldump.c: Updated call to init_alloc_root() client/mysqltest.cc: Updated call to init_alloc_root() Updated call to my_init_dynamic_array() Fixed compiler warnings extra/comp_err.c: Updated call to my_init_dynamic_array() extra/resolve_stack_dump.c: Updated call to my_init_dynamic_array() include/hash.h: Added HASH_THREAD_SPECIFIC include/heap.h: Added flag is internal temporary table. include/my_dir.h: Safety fix: Ensure that MY_DONT_SORT and MY_WANT_STAT don't interfer with other mysys flags include/my_global.h: Changed type of myf from int to ulong, as this is always a set of bit flags. include/my_sys.h: Added MY_THREAD_SPECIFIC and MY_THREAD_MOVE Added malloc_flags to DYNAMIC_ARRAY Added extra mysys flag argument to my_init_dynamic_array() Removed deprecated functions init_dynamic_array() and my_init_dynamic_array.._ci Updated paramaters for init_alloc_root() include/my_tree.h: Added my_flags to allow one to use MY_THREAD_SPECIFIC with hash tables.
