Mats Kindahl	e409d6f69c	WL#5030: Split and remove mysql_priv.h This patch: - Moves all definitions from the mysql_priv.h file into header files for the component where the variable is defined - Creates header files if the component lacks one - Eliminates all include directives from mysql_priv.h - Eliminates all circular include cycles - Rename time.cc to sql_time.cc - Rename mysql_priv.h to sql_priv.h	16 years ago
Staale Smedseng	04f1434781	Bug #45058 init_available_charsets uses double checked locking A client doing multiple mysql_library_init() and mysql_library_end() calls over the lifetime of the process may experience lost character set data, potentially even a SIGSEGV. This patch reinstates the reloading of character set data when a mysql_library_init() is done after a mysql_library_end().	16 years ago
Staale Smedseng	983770aa6a	Bug #45058 init_available_charsets uses double checked locking As documented in the bug report, the double checked locking pattern has inherent issues, and cannot guarantee correct initialization. This patch replaces the logic in init_available_charsets() with the use of pthread_once(3). A wrapper function, my_pthread_once(), is introduced and is used in lieu of direct calls to init_available_charsets(). Related defines MY_PTHREAD_ONCE_* are also introduced. For the Windows platform, the implementation in lp:sysbench is ported. For single-thread use, a simple define calls the function and sets the pthread_once control variable. Charset initialization is modified to use my_pthread_once().	16 years ago

Alexey Botchkov	96817d2483	Bug#47126 equal flag values causing unexpected behaviour Although the MY_SYNC_DIR flag supported in my_create(), my_delete(), my_rename() and my_symlink(), this feature is not used in the mysql code now. So technically we can declare the MY_SYNC_DIR as 0, but I decided to assign a new value for it as it's probably safer and worths nothing. per-file comments: include/my_sys.h Bug#47126 equal flag values causing unexpected behaviour assign unique value for the MY_SYNC_DIR	16 years ago

He Zhenxing	86c36aa1fd	Backport BUG#25192 Using relay-log and relay-log-index without values produces unexpected results. Options loaded from config files were added before command line arguments, and they were parsed together, which could interprete the following: option-a option-b as --option-a=--option-b if 'option-a' requires a value, and caused confusing. Because all options that requires a value are always given in the form '--option=value', so it's an error if there is no '=value' part for such an option read from config file. This patch added a separator to separate the arguments from config files and that from command line, so that they can be handled differently. And report an error for options loaded from config files that requires a value and is not given in the form '--option=value'.	16 years ago
Vladislav Vaintroub	6e6b84fd02	backport of Revision: 2597.72.1 revid:sp1r-Reggie@core.-20080403153947-15243 removed instances of __NT__ from code. We now only build "NT" binaries	16 years ago
Ingo Struewing	21586dfb08	WL#4259 - Debug Sync Facility Backport from 6.0 to 5.1. Only those sync points are included, which are used in debug_sync.test. The Debug Sync Facility allows to place synchronization points in the code: open_tables(...) DEBUG_SYNC(thd, "after_open_tables"); lock_tables(...) When activated, a sync point can - Send a signal and/or - Wait for a signal Nomenclature: - signal: A value of a global variable that persists until overwritten by a new signal. The global variable can also be seen as a "signal post" or "flag mast". Then the signal is what is attached to the "signal post" or "flag mast". - send a signal: Assign the value (the signal) to the global variable ("set a flag") and broadcast a global condition to wake those waiting for a signal. - wait for a signal: Loop over waiting for the global condition until the global value matches the wait-for signal. Please find more information in the top comment in debug_sync.cc or in the worklog entry.	16 years ago
Vladislav Vaintroub	4e92af9f43	This is the downport of Bug#24509 - 2048 file descriptor limit on windows needs increasing, also WL#3049 - improved Windows I/O 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. 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.	16 years ago

The mysql server option 'sync_frm' is ignored when table is created with syntax CREATE TABLE .. LIKE.. Fixed by adding the MY_SYNC flag and calling my_sync() from my_copy() when the flag is set.

He Zhenxing	e7605e338b	BUG#22082 Slave hangs(holds mutex) on "disk full" When disk is full, server may waiting for free space while writing binlog, relay-log or MyISAM tables. The server will continue after user have freed some space. But the error message printed was not quite clear about the how often the error message is printed, and there will be a delay before the server continue and user freeing space. And caused users thinking that the server was hanging forever. This patch fixed the problem by making the error messages printed more clear. The error message is split into two part, the first part will only be printed once, and the second part will be printed very 10 times. Message first part: Disk is full writing '<filename>' (Errcode: <errorno>). Waiting for someone to free space... (Expect up to 60 secs delay for server to continue after freeing disk space) Message second part: Retry in 60 secs, Message reprinted in 600 secs	17 years ago
Alexey Kopytov	752cbab9a4	Fix for bug #40552 : Race condition around default_directories in load_defaults() load_defaults(), my_search_option_files() and my_print_default_files() utilized a global variable containing a pointer to thread local memory. This could lead to race conditions when those functions were called with high concurrency. Fixed by changing the interface of the said functions to avoid the necessity for using a global variable. Since we cannot change load_defaults() prototype for API compatibility reasons, it was renamed my_load_defaults(). Now load_defaults() is a thread-unsafe wrapper around a thread-safe version, my_load_defaults().	17 years ago

Alexey Botchkov	cf0d0a5e96	Bug#37995 Error message truncation in test "innodb" in embedded mode. code backported from 6.0 per-file messages: include/my_global.h Remove SC_MAXWIDTH. This is unused and irrelevant nowadays. include/my_sys.h Remove errbuf declaration and unused definitions. mysys/my_error.c Remove errbuf definition and move and adjust ERRMSGSIZE. mysys/my_init.c Declare buffer on the stack and use my_snprintf. mysys/safemalloc.c Use size explicitly. It's more than enough for the message at hand. sql/sql_error.cc Use size explicitly. It's more than enough for the message at hand. sql/sql_parse.cc Declare buffer on the stack. Use my_snprintf as it will result in less stack space being used than by a system provided sprintf -- this allows us to put the buffer on the stack without causing much trouble. Also, the use of errbuff here was not thread-safe as the function can be entered concurrently from multiple threads. sql/sql_table.cc Use MYSQL_ERRMSG_SIZE. Extra space is not needed as my_snprintf will nul terminate strings. storage/myisam/ha_myisam.cc Use MYSQL_ERRMSG_SIZE. sql/share/errmsg.txt Error message truncation in test "innodb" in embedded mode filename in the error message can safely take up to 210 symbols.	17 years ago

tsmith@ramayana.hindu.god	ef59ca3d78	Bug #20748 : Configuration files should not be read more than once A user could not override system-wide settings in their ~/.my.cnf, because the DEFAULT_SYSCONFDIR was being searched last. Also, in some configurations (especially when the --sysconfdir compile-time option is set to /etc or /etc/mysql), the system-wide my.cnf file was read multiple times, causing confusion and potential problems. Rearrange default directories to conform to the manual and logic. Move --sysconfdir=<path> (DEFAULT_SYSCONFDIR) from the last default directory to the middle of the list. $HOME/.my.cnf should be last, so the user is able to override the system-wide settings. Change init_default_directories() to remove duplicates from the list.	18 years ago

kaa@polly.(none)	04b1c9ca40	Post-merge changes for bug #31207 : Test "join_nested" shows different strategy on IA64 CPUs / Intel's ICC compiler.	18 years ago
kaa@polly.(none)	6d1f3e8de5	Fix for bug #31207 : Test "join_nested" shows different strategy on IA64 CPUs / Intel's ICC compile The bug is a combination of two problems: 1. IA64/ICC MySQL binaries use glibc's qsort(), not the one in mysys. 2. The order relation implemented by join_tab_cmp() is not transitive, i.e. it is possible to choose such a, b and c that (a < b) && (b < c) but (c < a). This implies that result of a sort using the relation implemented by join_tab_cmp() depends on the order in which elements are compared, i.e. the result is implementation-specific. Since choose_plan() uses qsort() to pre-sort the join tables using join_tab_cmp() as a compare function, the results of the sorting may vary depending on qsort() implementation. It is neither possible nor important to implement a better ordering algorithm in join_tab_cmp(). Therefore the only way to fix it is to force our own qsort() to be used by renaming it to my_qsort(), so we don't depend on linker to decide that. This patch also "fixes" bug #20530: qsort redefinition violates the standard.	18 years ago

anozdrin/alik@ibm.	9fae9ef66f	Patch for the following bugs: - BUG#11986: Stored routines and triggers can fail if the code has a non-ascii symbol - BUG#16291: mysqldump corrupts string-constants with non-ascii-chars - BUG#19443: INFORMATION_SCHEMA does not support charsets properly - BUG#21249: Character set of SP-var can be ignored - BUG#25212: Character set of string constant is ignored (stored routines) - BUG#25221: Character set of string constant is ignored (triggers) There were a few general problems that caused these bugs: 1. Character set information of the original (definition) query for views, triggers, stored routines and events was lost. 2. mysqldump output query in client character set, which can be inappropriate to encode definition-query. 3. INFORMATION_SCHEMA used strings with mixed encodings to display object definition; 1. No query-definition-character set. In order to compile query into execution code, some extra data (such as environment variables or the database character set) is used. The problem here was that this context was not preserved. So, on the next load it can differ from the original one, thus the result will be different. The context contains the following data: - client character set; - connection collation (character set and collation); - collation of the owner database; The fix is to store this context and use it each time we parse (compile) and execute the object (stored routine, trigger, ...). 2. Wrong mysqldump-output. The original query can contain several encodings (by means of character set introducers). The problem here was that we tried to convert original query to the mysqldump-client character set. Moreover, we stored queries in different character sets for different objects (views, for one, used UTF8, triggers used original character set). The solution is - to store definition queries in the original character set; - to change SHOW CREATE statement to output definition query in the binary character set (i.e. without any conversion); - introduce SHOW CREATE TRIGGER statement; - to dump special statements to switch the context to the original one before dumping and restore it afterwards. Note, in order to preserve the database collation at the creation time, additional ALTER DATABASE might be used (to temporary switch the database collation back to the original value). In this case, ALTER DATABASE privilege will be required. This is a backward-incompatible change. 3. INFORMATION_SCHEMA showed non-UTF8 strings The fix is to generate UTF8-query during the parsing, store it in the object and show it in the INFORMATION_SCHEMA. Basically, the idea is to create a copy of the original query convert it to UTF8. Character set introducers are removed and all text literals are converted to UTF8. This UTF8 query is intended to provide user-readable output. It must not be used to recreate the object. Specialized SHOW CREATE statements should be used for this. The reason for this limitation is the following: the original query can contain symbols from several character sets (by means of character set introducers). Example: - original query: CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1; - UTF8 query (for INFORMATION_SCHEMA): CREATE VIEW v1 AS SELECT 'Hello' AS c1;	19 years ago

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	19 years ago
