Problem: In cases when a client-side macro appears inside a server-side comment, the add_line() function in mysql.cc discarded all characters until the next delimiter to remove macro arguments from the query string. This resulted in broken queries being sent to the server when the next delimiter character appeared past the comment's boundaries, because the comment closing sequence ('*/') was discarded. Fix: If a client-side macro appears inside a server-side comment, discard all characters in the comment after the macro (that is, until the end of the comment rather than the next delimiter). This is a minimal fix to allow only simple cases used by the mysqlbinlog utility. Limitations that are worth documenting: - Nested server-side and/or client-side comments are not supported by mysql.cc - Using client-side macros in multi-line server-side comments is not supported - All characters after a client-side macro in a server-side comment will be omitted from the query string (and thus, will not be sent to server). client/mysql.cc: If a client-side macro appears inside a server-side comment, discard all characters in the comment after the macro. mysql-test/r/mysql.result: Added a test case for bug #30164. mysql-test/t/mysql.test: Added a test case for bug #30164.

This is a performance bug, affecting in particular the bison generated code for the parser. Prior to this fix, the grammar used a long chain of reduces to parse an expression, like: bit_expr -> bit_term bit_term -> bit_factor bit_factor -> value_expr value_expr -> term term -> factor etc This chain of reduces cause the internal state automaton in the generated parser to execute more state transitions and more reduces, so that the generated MySQLParse() function would spend a lot of time looping to execute all the grammar reductions. With this patch, the grammar has been reorganized so that rules are more "flat", limiting the depth of reduces needed to parse <expr>. Tests have been written to enforce that relative priorities and properties of operators have not changed while changing the grammar. See the bug report for performance data. mysql-test/r/parser_precedence.result: Improved test coverage for operator precedence mysql-test/t/parser_precedence.test: Improved test coverage for operator precedence sql/sql_yacc.yy: Simplified the grammar to improve performances

If, after the tables are locked, one of the conditions to read from a HANDLER table is not met, the handler code wrongly jumps to a error path that won't unlock the tables. The user-visible effect is that after a error in a handler read command, all subsequent handler operations on the same table will hang. The fix is simply to correct the code to jump to the (same) error path that unlocks the tables. mysql-test/r/handler.result: Bug#30632 test case result mysql-test/t/handler.test: Bug#30632 test case sql/sql_handler.cc: Always unlock the internal and external table level locks if any of the conditions (including errors) to read from a HANDLER table are not met.

The problem from a user's perspective: user creates table A, and then tries to CREATE TABLE a SELECT from A - and this causes a deadlock error, a hang, or fails with a debug assert, but only if the storage engine is InnoDB. The origin of the problem: InnoDB uses case-insensitive collation (system_charset_info) when looking up the internal table share, thus returning the same share for 'a' and 'A'. Cause of the user-visible behavior: since the same share is returned to SQL locking subsystem, it assumes that the same table is first locked (within the same session) for WRITE, and then for READ, and returns a deadlock error. However, the code is wrong in not properly cleaning up upon an error, leaving external locks in place, which leads to assertion failures and hangs. Fix that has been implemented: the SQL layer should properly propagate the deadlock error, cleaning up and freeing all resources. Further work towards a more complete solution: InnoDB should not use case insensitive collation for table share hash if table names on disk honor the case. mysql-test/r/innodb-deadlock.result: Bug#25164 test case result mysql-test/t/innodb-deadlock.test: Bug#25164 test case. The CREATE TABLE may fail depending on the character set of the system and filesystem, but it should never hang. sql/lock.cc: Unlock the storage engine "external" table level locks, if the MySQL thr_lock locking subsystem detects a deadlock error.

since this flag was explicitly removed in pushbuild for GCOV builds. BUILD_CMD => ['sh', '-c', 'perl -i.bak -pe "s/ \\\\\$static_link//" ' . 'BUILD/compile-pentium-gcov; BUILD/compile-pentium-gcov'], Moving $static_link to SETUP.sh broke this, and is now fixed. Should this flag be needed on some platforms, the proper location is compile-<platform>-gcov Tested the amd64 and pentium64 build fine without it, and can run NDB tests. BUILD/SETUP.sh: Removed $static_link from GCOV builds.

This is a performance bug, related to the parsing or 'OR' and 'AND' boolean expressions. Let N be the number of expressions involved in a OR (respectively AND). When N=1 For example, "select 1" involve only 1 term: there is no OR operator. In 4.0 and 4.1, parsing expressions not involving OR had no overhead. In 5.0, parsing adds some overhead, with Select->expr_list. With this patch, the overhead introduced in 5.0 has been removed, so that performances for N=1 should be identical to the 4.0 performances, which are optimal (there is no code executed at all) The overhead in 5.0 was in fact affecting significantly some operations. For example, loading 1 Million rows into a table with INSERTs, for a table that has 100 columns, leads to parsing 100 Millions of expressions, which means that the overhead related to Select->expr_list is executed 100 Million times ... Considering that N=1 is by far the most probable expression, this case should be optimal. When N=2 For example, "select a OR b" involves 2 terms in the OR operator. In 4.0 and 4.1, parsing expressions involving 2 terms created 1 Item_cond_or node, which is the expected result. In 5.0, parsing these expression also produced 1 node, but with some extra overhead related to Select->expr_list : creating 1 list in Select->expr_list and another in Item_cond::list is inefficient. With this patch, the overhead introduced in 5.0 has been removed so that performances for N=2 should be identical to the 4.0 performances. Note that the memory allocation uses the new (thd->mem_root) syntax directly. The cost of "is_cond_or" is estimated to be neglectable: the real problem of the performance degradation comes from unneeded memory allocations. When N>=3 For example, "select a OR b OR c ...", which involves 3 or more terms. In 4.0 and 4.1, the parser had no significant cost overhead, but produced an Item tree which is difficult to evaluate / optimize during runtime. In 5.0, the parser produces a better Item tree, using the Item_cond constructor that accepts a list of children directly, but at an extra cost related to Select->expr_list. With this patch, the code is implemented to take the best of the two implementations: - there is no overhead with Select->expr_list - the Item tree generated is optimized and flattened. This is achieved by adding children nodes into the Item tree directly, with Item_cond::add(), which avoids the need for temporary lists and memory allocation Note that this patch also provide an extra optimization, that the previous code in 5.0 did not provide: expressions are flattened in the Item tree, based on what the expression already parsed is, and not based on the order in which rules are reduced. For example : "(a OR b) OR c", "a OR (b OR c)" would both be represented with 2 Item_cond_or nodes before this patch, and with 1 node only with this patch. The logic used is based on the mathematical properties of the OR operator (it's associative), and produces a simpler tree. sql/item_cmpfunc.h: Improved performances for parsing boolean expressions sql/sql_yacc.yy: Improved performances for parsing boolean expressions mysql-test/r/parser_precedence.result: Added test cases to cover boolean operator precedence mysql-test/t/parser_precedence.test: Added test cases to cover boolean operator precedence

This is a follow up for the patch for Bug#26162 "Trigger DML ignores low_priority_updates setting", where the stored procedure ignores the session setting of low_priority_updates. For every table open operation with default write (TL_WRITE_DEFAULT) lock_type, downgrade the lock type to the session setting of low_priority_updates. sql/lock.cc: Add late lock_type assertion. sql/sql_base.cc: Possibly downgrade lock type to the the session setting of low_priority_updates and also remove early assertion.

This patch provides compile helper scripts only, no server logic is affected. Before this patch, GCOV and GPROF build scripts were only provided for pentium platforms. With this patch, pentium, pentium64 and amd64 platforms have associated helper build scripts. The GCOV and GPROF specific compilation flags are set once in SETUP.sh, to avoid code duplication. BUILD/SETUP.sh: Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh BUILD/compile-pentium-gcov: Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh BUILD/compile-pentium-gprof: Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh BUILD/compile-amd64-gcov: Added helper scripts for GCOV and GPROF builds. BUILD/compile-amd64-gprof: Added helper scripts for GCOV and GPROF builds. BUILD/compile-pentium64-gcov: Added helper scripts for GCOV and GPROF builds. BUILD/compile-pentium64-gprof: Added helper scripts for GCOV and GPROF builds.

There was a special upgraded lock mode (TL_WRITE instead of TL_WRITE_ALLOW_READ) in ALTER TABLE to make sure nobody has the table opened when deleting the old table in ALTER TABLE. This special mode was causing ALTER TABLE to hang waiting on a lock inside InnoDB. This special lock is no longer necessary as the server is closing the tables it needs to delete in ALTER TABLE. Fixed by removing the special lock. Note that this also reverses the fix for bug 17264 that deals with another consequence of this special lock mode being used. sql/ha_innodb.cc: Bug 29644: reverse the (now excessive) fix for bug 17264 (but leave the test case).

When innodb detects a deadlock it calls ha_rollback_trans() to rollback the main transaction. But such action isn't allowed from inside of triggers and functions. When it happen the 'Explicit or implicit commit' error is thrown even if there is no commit/rollback statements in the trigger/function. This leads to the user confusion. Now the convert_error_code_to_mysql() function doesn't call the ha_rollback_trans() function directly but rather calls the mark_transaction_to_rollback function and returns an error. The sp_rcontext::find_handler() now doesn't allow errors to be caught by the trigger/function error handlers when the thd->is_fatal_sub_stmt_error flag is set. Procedures are still allowed to catch such errors. The sp_rcontext::find_handler function now accepts a THD handle as a parameter. The transaction_rollback_request and the is_fatal_sub_stmt_error flags are added to the THD class. The are initialized by the THD class constructor. Now the ha_autocommit_or_rollback function rolls back main transaction when not in a sub statement and the thd->transaction_rollback_request is set. The THD::restore_sub_statement_state function now resets the thd->is_fatal_sub_stmt_error flag on exit from a sub-statement. innodb-big.test, innodb-big.result: Added a test case for the bug 24989: The DEADLOCK error is improperly handled by InnoDB. sql/ha_innodb.cc: Bug 24989: The DEADLOCK error is improperly handled by InnoDB.
