* MDEV-27142 - postfixVladislav Vaintroub2022-11-041-0/+2
| | | | | | | | Fix build failure in comp_err, if git is configured with default, platform-specific EOL. The error happens because comp_err is not prepared to handle extraneous CR characters from errmgs-utf8.txt. Use fopen in text mode to fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the following to statistic counters: * my_file_opened * my_file_total_opened * my_stream_opened * my_tmp_file_created There is one non-statistics use of my_file_opened/my_stream_opened in my_end which prints a warning if we shutdown and its still open. It seems excessive to hold locks to prevent this warning. A file descriptor is already a unique element per process - in Windows, protection occurs at fd allocation using THR_LOCK_open in my_win_{,f}open and in other OSes, a unique fd to file map exists at the OS level. So accesses to my_file_info[fd] don't need to be protected by the THR_LOCK_open. my_close/my_fclose where restructured to clear out the my_file_info before the close/my_win_close/my_win_fclose. After these calls another thread could gain the same file descriptor. So for Windows this the file_info elements available to the my_win_{,f}_open are released during the invalidate_fd call within my_win_close. No locking is needed as the my_win_{,f}open is searching for a invalidate entry which is determined by a single value change. my_fclose also changed for non-Windows to retry closing if EINTR was returned, same as my_close. Closes #657

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.

The patch replaces the use of the POSIX I/O interfaces in mysys on Windows with the Win32 API calls (CreateFile, WriteFile, etc). The Windows HANDLE for the open file is stored in the my_file_info struct, along with a flag for append mode (because the Windows API does not support opening files in append mode in all cases) The default max open files has been increased to 16384 and can be increased further by setting --max-open-files=<value> during the server start. Noteworthy benefit of this patch is that it removes limits from the table_cache size - allowing for more simultaneus users

In the case of this bug report, the streams would end up associated to InnoDB ibd files. The freopen(3) function is not thread-safe on FreeBSD. What this means is that if another thread calls open(2) during freopen() is executing that another thread's fd returned by open(2) may get re-associated with the file being passed to freopen(3). See FreeBSD PR number 79887 for reference: http://www.freebsd.org/cgi/query-pr.cgi?pr=79887 This problem is worked around by substituting a internal hook within the FILE structure. This avoids the loss of atomicity by not having the original fd closed before its duplicated. Patch based on the original work by Vasil Dimov. include/my_sys.h: Export my_freopen. mysys/my_fopen.c: Add a my_freopen abstraction to workaround bugs in specific OSes. Add a prototype for getosreldate() as older FreeBSD versions did not define one. sql/log.cc: Move freopen abstraction code over to mysys. The streams are now only reopened for writing.

* | Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabledDavi Arnaut2010-07-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. client/mysqldump.c: Pass my_free directly as its signature is compatible with the callback type -- which wasn't the case for free_table_ent.

The Windows HANDLE for the open file is stored in the my_file_info struct, along with a flag for append mode because the Windows API does not support opening files in append mode in all cases) The default max open files has been increased to 16384 and can be increased further by setting --max-open-files=<value> during the server start. Another major change in this patch that almost all Windows specific file IO code has been moved to a new file my_winfile.c, greatly reducing the amount of code in #ifdef blocks within mysys, thus improving readability. Minor enhancements: - my_(f)stat() is changed to use __stati64 structure with 64 file size and timestamps. It will return correct file size now (C runtime implementation used to report outdated information) - my_lock on Windows is prepared to handle additional timeout parameter - after review : changed __WIN__ to _WIN32 in the new and changed code. client/mysqlbinlog.cc: fileno -> my_fileno client/readline.cc: fileno -> my_fileno include/config-win.h: Increase OS_FILE_LIMIT for Windows. Remove O_SHARE - Windows does not support it. Its definition conflicts with O_SHORT_LIVED, that has different semantics. include/my_dir.h: Use stat64 for stat() family of functions on Windows, because of 64 bit file size. include/my_global.h: Increased default value for open file limit to 16K include/my_sys.h: - my_file_info got new structure members - file handle and open flags - 2 new Windows-only mysys functions : my_get_osfhandle and my_osmaperr, modelled after Windows C runtime functions _get_osfhandle and _dosmaperr libmysql/CMakeLists.txt: new files my_winfile.c and my_winerr.c mysql-test/suite/large_tests/r/lock_tables_big.result: test for more then 2048 open file descriptors on Windows mysql-test/suite/large_tests/t/lock_tables_big.test: test for more then 2048 open file descriptors on Windows mysys/CMakeLists.txt: new files my_winfile.c and my_winerr.c mysys/Makefile.am: new files my_winfile.c and my_winerr.c mysys/default_modify.c: fileno -> my_fileno mysys/my_chsize.c: implementation of chsize on Windows now moved to my_winfile.c mysys/my_create.c: - my_sopen->my_win_open - close open file before removing (won't generally work on Windows otherwise) mysys/my_file.c: On Windows, files returned by my_open will not start with 0, but 2048 (making it simple to detect incompatible mix of CRT and mysys io functions) mysys/my_fopen.c: fileno->my_win_fileno , fclose->my_win_fclose, fdopen->my_win_fdopen Check for legal filename is done by my_win_[f]open functions mysys/my_fstream.c: fileno->my_fileno mysys/my_lib.c: Windows stat() functions are moved to my_winfile.c mysys/my_lock.c: Move Windows code under #ifdef to a separate function win_lock().

The problem with _dosmaperr() used previously is that 1) it is nowhere documented and thus code relying on it is not guaranteed to work in subsequent releases on the C runtime 2) it is present only in static C runtime (mysqld does not link if compiled with /MD) mysys/my_winfile.c: New file my_winfile.c Implements ANSI/Posix file IO routines, when possible using native Windows IO, without C runtime (C runtime dropped because of the 2048 file descriptor limit). mysys/my_write.c: write->my_win_write mysys/mysys_priv.h: Declaration of Windows Posix functions (private to mysys, shall not be visible outside) storage/innobase/handler/ha_innodb.cc: mysys native Windows IO : correct innodb tmp file handling mysql_tmpfile does not return valid CRT file descriptor, thus it is not possible to dup() it. Instead, the native file handle has to be duplicated and then converted to CRT descriptor. storage/myisam/mi_locking.c: _commit->my_sync
