Davi Arnaut	0eb26fdfa8	Bug#53445: Build with -Wall and fix warnings that it generates Apart strict-aliasing warnings, fix the remaining warnings generated by GCC 4.4.4 -Wall and -Wextra flags. One major source of warnings was the in-house function my_bcmp which (unconventionally) took pointers to unsigned characters as the byte sequences to be compared. Since my_bcmp and bcmp are deprecated functions whose only difference with memcmp is the return value, every use of the function is replaced with memcmp as the special return value wasn't actually being used by any caller. There were also various other warnings, mostly due to type mismatches, missing return values, missing prototypes, dead code (unreachable) and ignored return values. BUILD/SETUP.sh: Remove flags that are implied by -Wall and -Wextra. Do not warn about unused parameters in C++. BUILD/check-cpu: Print only the compiler version instead of verbose banner. Although the option is gcc specific, the check was only being used for GCC specific checks anyway. client/mysql.cc: bcmp is no longer defined. client/mysqltest.cc: Pass a string to function expecting a format string. Replace use of bcmp with memcmp. cmd-line-utils/readline/Makefile.am: Always define _GNU_SOURCE when compiling GNU readline. Required to make certain prototypes visible. cmd-line-utils/readline/input.c: Condition for the code to be meaningful. configure.in: Remove check for bcmp. extra/comp_err.c: Use appropriate type. extra/replace.c: Replace use of bcmp with memcmp. extra/yassl/src/crypto_wrapper.cpp: Do not ignore the return value of fgets. Retrieve the file position if fgets succeed -- if it fails, the function will bail out and return a error. extra/yassl/taocrypt/include/blowfish.hpp: Use a single array instead of accessing positions of the sbox_ through a subscript to pbox_. extra/yassl/taocrypt/include/runtime.hpp: One definition of such functions is enough. extra/yassl/taocrypt/src/aes.cpp: Avoid potentially ambiguous conditions. extra/yassl/taocrypt/src/algebra.cpp: Rename arguments to avoid shadowing related warnings. extra/yassl/taocrypt/src/blowfish.cpp: Avoid potentially ambiguous conditions. extra/yassl/taocrypt/src/integer.cpp: Do not define type within a anonymous union. Use a variable to return a value instead of leaving the result in a register -- compiler does not know the logic inside the asm. extra/yassl/taocrypt/src/misc.cpp: Define handler for pure virtual functions. Remove unused code. extra/yassl/taocrypt/src/twofish.cpp: Avoid potentially ambiguous conditions. extra/yassl/testsuite/test.hpp: Function must have C language linkage. include/m_string.h: Remove check which relied on bcmp being defined -- they weren't being used as bcmp is only visible when _BSD_SOURCE is defined. include/my_bitmap.h: Remove bogus helpers which were used only in a few files and were causing warnings about dead code. include/my_global.h: Due to G++ bug, always silence false-positive uninitialized variables warnings when compiling C++ code with G++.

No need to use helpers for simple bit operations. sql/log_event_old.cc: Replace bmove_align with memcpy. sql/mysqld.cc: Move use declaration of variable to the ifdef block where it is used. Remove now-unnecessary casts and arguments. sql/set_var.cc: Replace bogus helpers with simple and classic bit operations. sql/slave.cc: Cast to expected type and silence bogus warning. sql/sql_class.h: Don't use enum values as bit flags, the supposed type safety is bogus as the combined bit flags are not a value in the enumeration. sql/udf_example.c: Only declare variable when necessary. sql/unireg.h: Replace use of bmove_align with memcpy. storage/innobase/os/os0file.c: Silence bogus warning. storage/myisam/mi_open.c: Remove bogus cast, DBUG_DUMP expects a pointer to unsigned char. storage/myisam/mi_page.c: Remove bogus cast, DBUG_DUMP expects a pointer to unsigned char. strings/bcmp.c: Remove built-in bcmp. strings/ctype-ucs2.c: Silence bogus warning. tests/mysql_client_test.c: Use a appropriate type as expected by simple_command().	16 years ago

Sergey Glukhov	1c5388765f	Bug#51431 Wrong sort order after import of dump file The problem is that QUICK_SELECT_DESC behaviour depends on used_key_parts value which can be bigger than selected best_key_parts value if an engine supports clustered key. But used_key_parts is overwritten with best_key_parts value that prevents from correct selection of index access method. The fix is to preserve used_key_parts value for further use in QUICK_SELECT_DESC. mysql-test/r/innodb_mysql.result: test case mysql-test/t/innodb_mysql.test: test case sql/sql_select.cc: preserve used_key_parts value for further use in QUICK_SELECT_DESC	16 years ago
Staale Smedseng	18388d2105	Bug #53899 Wrong mysql_stmt_errno() after connection loss with automatic reconnect A client with automatic reconnect enabled will see the error message "Lost connection to MySQL server during query" if the connection is lost between mysql_stmt_prepare() and mysql_stmt_execute(). The mysql_stmt_errno() number, however, is 0 -- not the corresponding value 2013. This patch checks for the case where the prepared statement has been pruned due to a connection loss (i.e., stmt->mysql has been set to NULL) during a call to cli_advanced_command(), and avoids changing the last_errno to the result of the last reconnect attempt.	16 years ago

Davi Arnaut	715bac92ba	Bug#54457: Test suite broken for 32-bit build The default value of the myisam_max_extra_sort_file_size could be higher than the maximum accepted value, leading to warnings upon the server start. The solution is to simply set the value to the maximum value in a 32-bit built (2147483647, one less than the current). This should be harmless as the option is currently unused in 5.1. include/myisam.h: Remove now-unused macro. sql/mysqld.cc: Set max value to INT_MAX32.	16 years ago
Davi Arnaut	e42d90850c	Bug#54041: MySQL 5.0.92 fails when tests from Connector/C suite run The problem was that a user could supply supply data in chunks via the COM_STMT_SEND_LONG_DATA command to prepared statement parameter other than of type TEXT or BLOB. This posed a problem since other parameter types aren't setup to handle long data, which would lead to a crash when attempting to use the supplied data. Given that long data can be supplied at any stage of a prepared statement, coupled with the fact that the type of a parameter marker might change between consecutive executions, the solution is to validate at execution time each parameter marker for which a data stream was provided. If the parameter type is not TEXT or BLOB (that is, if the type is not able to handle a data stream), a error is returned. sql/sql_prepare.cc: Before converting the parameter data stream, check the type compatibility. tests/mysql_client_test.c: Add test case.	16 years ago

unknown	451cea3f62	The following statements support the CURRENT_USER() where a user is needed. DROP USER RENAME USER CURRENT_USER() ... GRANT ... TO CURRENT_USER() REVOKE ... FROM CURRENT_USER() ALTER DEFINER = CURRENT_USER() EVENTbut, When these statements are binlogged, CURRENT_USER() just is binlogged as 'CURRENT_USER()', it is not expanded to the real user name. When slave executes the log event, 'CURRENT_USER()' is expand to the user of slave SQL thread, but SQL thread's user name always NULL. This breaks the replication. After this patch, session's user will be written into query log events if these statements call CURREN_USER() or 'ALTER EVENT' does not assign a definer. mysql-test/include/diff_tables.inc: Expend its abilities. Now it can diff not only in sessions of 'master' and 'slave', but other sessions as well. mysql-test/include/rpl_diff_tables.inc: Diff the same table between master and slaves. sql/log_event.cc: session's user will be written into Query_log_event, if is_current_user_used() is TRUE.

Jon Olav Hauglid	b4593605e0	Bug #54360 Deadlock DROP/ALTER/CREATE DATABASE with open HANDLER This deadlock happened if DROP DATABASE was blocked due to an open HANDLER table from a different connection. While DROP DATABASE is blocked, it holds the LOCK_mysql_create_db mutex. This results in a deadlock if the connection with the open HANDLER table tries to execute a CREATE/ALTER/DROP DATABASE statement as they all try to acquire LOCK_mysql_create_db. This patch makes this deadlock scenario very unlikely by closing and marking for re-open all HANDLER tables for which there are pending conflicing locks, before LOCK_mysql_create_db is acquired. However, there is still a very slight possibility that a connection could access one of these HANDLER tables between closing/marking for re-open and the acquisition of LOCK_mysql_create_db. This patch is for 5.1 only, a separate and complete fix will be made for 5.5+. Test case added to schema.test.	16 years ago

Alexey Kopytov	0e6560398c	Bug#54477: Crash on IN / CASE with NULL arguments Incorrect handling of NULL arguments could lead to a crash on the IN or CASE operations when either NULL arguments were passed explicitly as arguments (IN) or implicitly generated by the WITH ROLLUP modifier (both IN and CASE). Item_func_case::find_item() assumed all necessary comparators to be instantiated in fix_length_and_dec(). However, in the presence of WITH ROLLUP modifier, arguments could be substituted with an Item_null leading to an "unexpected" STRING_RESULT comparator being invoked. In addition to the problem identical to the above, Item_func_in::val_int() could crash even with explicitly passed NULL arguments due to an optimization in fix_length_and_dec() leading to NULL arguments being ignored during comparators creation. mysql-test/r/func_in.result: Test cases for bug#54477. mysql-test/t/func_in.test: Test cases for bug#54477. sql/item_cmpfunc.cc: Added additional checks for Item_nulls in Item_func_case::find_item() and Item_func_in::val_int().	16 years ago

Joerg Bruehe	b3eac87c3c	Fix bug#27072: RPM autostarts the server This is the fix for 5.1, where only the behaviour on upgrade is changed: If the server was stopped when the upgrade begins, we assume the administrator is taking manual action, so we do not start the (new) server at the end of the upgrade. We still install the start/stop script, so it will be started on reboot. support-files/mysql.spec.sh: In the "pre" section of the spec file, check the server status, and write the result to a file. In the "post" section, evaluate the status file, and start the server if it was running during status analysis. In 5.1, we start the server if there is no status file (which will happen on first installation, when there is no data directory yet).	16 years ago

Martin Hansson	0823afc8bf	Bug#53859: Valgrind: opt_sum_query(TABLE_LIST, List<Item>&, Item) at opt_sum.cc:305 Queries applying MIN/MAX functions to indexed columns are optimized to read directly from the index if all key parts of the index preceding the aggregated key part are bound to constants by the WHERE clause. A prefix length is also produced, equal to the total length of the bound key parts. If the aggregated column itself is bound to a constant, however, it is also included in the prefix. Such full search keys are read as closed intervals for reasons beyond the scope of this bug. However, the procedure missed one case where a key part meant for use as range endpoint was being overwritten with a NULL value destined for equality checking. In this case the key part was overwritten but the range flag remained, causing open interval reading to be performed. Bug was fixed by adding more stringent checking to the search key building procedure (matching_cond) and never allow overwrites of range predicates with non-range predicates. An assertion was added to make sure open intervals are never used with full search keys.	16 years ago
Davi Arnaut	0f9ddfa9d8	Bug#42733: Type-punning warnings when compiling MySQL -- strict aliasing violations. One somewhat major source of strict-aliasing violations and related warnings is the SQL_LIST structure. For example, consider its member function `link_in_list` which takes a pointer to pointer of type T (any type) as a pointer to pointer to unsigned char. Dereferencing this pointer, which is done to reset the next field, violates strict-aliasing rules and might cause problems for surrounding code that uses the next field of the object being added to the list. The solution is to use templates to parametrize the SQL_LIST structure in order to deference the pointers with compatible types. As a side bonus, it becomes possible to remove quite a few casts related to acessing data members of SQL_LIST. sql/handler.h: Use the appropriate template type argument. sql/item.cc: Remove now-unnecessary cast. sql/item_subselect.cc: Remove now-unnecessary casts. sql/item_sum.cc: Use the appropriate template type argument.

Davi Arnaut	6f3a540c37	Bug#42733: Type-punning warnings when compiling MySQL -- strict aliasing violations. Essentially, the problem is that large parts of the server were developed in simpler times (last decades, pre C99 standard) when strict aliasing and compilers supporting such optimizations were rare to non-existent. Thus, when compiling the server with a modern compiler that uses strict aliasing rules to perform optimizations, there are several places in the code that might trigger undefined behavior. As evinced by some recent bugs, GCC does a somewhat good of job misoptimizing such code, but on the other hand also gives warnings about suspicious code. One problem is that the warnings aren't always accurate, yet we can't afford to just shut them off as we might miss real cases. False-positive cases are aggravated mostly by casts that are likely to trigger undefined behavior. The solution is to start a cleanup process focused on fixing and reducing the amount of strict-aliasing related warnings produced by GCC and others compilers. A good deal of noise reduction can be achieved by just removing useless casts that are product of historical cruft and are likely to trigger undefined behavior if dereferenced. client/mysql.cc: Remove now-unnecessary casts.
