From f7886540120d6c9d564053ee25709f07fd49a784 Mon Sep 17 00:00:00 2001 From: unknown Date: Tue, 25 Sep 2007 12:01:23 +0200 Subject: [PATCH 01/36] [PATCH] BUG#30379 Better randomise time before retry in timeout check (DBTC) timoOutLoopStartLab() checks if any transactions have been delayed for so long that we are forced to perform some action (e.g. abort, resend etc). It is *MEANT* to (according to the comment): > To avoid aborting both transactions in a deadlock detected by time-out > we insert a random extra time-out of upto 630 ms by using the lowest > six bits of the api connect reference. > We spread it out from 0 to 630 ms if base time-out is larger than 3 sec, > we spread it out from 0 to 70 ms if base time-out is smaller than 300 msec, > and otherwise we spread it out 310 ms. The comment (as all do) lies. the API connect reference is not very random, producing incredibly predictable "random" numbers. This could lead to both txns being aborted instead of just one.

The problem was integer overflow. Affects 4.1 only. myisam/ft_boolean_search.c: my_match_t::beg is unsigned int, that means type of expression (m[0].beg - 1) has unsigned type too. It may happen that instr() finds substring in the beggining of passed string, returning m[0].beg equal to 0. In this case value of expression (m[0].beg - 1) is equal to MAX_UINT. This is not a problem on platforms where sizeof(pointer) equals to sizeof(uint). That means ptr[(uint)-1] = ptr[(uint)MAX_UINT] = ptr - 1. On some 64-bit platforms where sizeof(pointer) is 8 and sizeof(uint) is 4, wrong address gets accessed. In other words ptr[(uint)-1] is equal to ptr + MAX_UINT. mysql-test/r/fulltext.result: A test case for BUG#11392. mysql-test/t/fulltext.test: A test case for BUG#11392. --- myisam/ft_boolean_search.c | 3 ++- mysql-test/r/fulltext.result | 6 ++++++ mysql-test/t/fulltext.test | 8 ++++++++ 3 files changed, 16 insertions(+), 1 deletion(-) diff --git a/myisam/ft_boolean_search.c b/myisam/ft_boolean_search.c index f1ff8f6d886..fad25abcc6c 100644 --- a/myisam/ft_boolean_search.c +++ b/myisam/ft_boolean_search.c @@ -446,7 +446,8 @@ static int _ftb_strstr(const byte *s0, const byte *e0, { if (cs->coll->instr(cs, p0, e0 - p0, s1, e1 - s1, m, 2) != 2) return(0); - if ((!s_after || p0 + m[1].beg == s0 || !true_word_char(cs, p0[m[1].beg-1])) && + if ((!s_after || p0 + m[1].beg == s0 || + !true_word_char(cs, p0[(int) m[1].beg - 1])) && (!e_before || p0 + m[1].end == e0 || !true_word_char(cs, p0[m[1].end]))) return(1); p0+= m[1].beg; diff --git a/mysql-test/r/fulltext.result b/mysql-test/r/fulltext.result index 3700ace4b19..af41adf3a24 100644 --- a/mysql-test/r/fulltext.result +++ b/mysql-test/r/fulltext.result @@ -454,3 +454,9 @@ ALTER TABLE t1 DISABLE KEYS; SELECT * FROM t1 WHERE MATCH(a) AGAINST('test'); ERROR HY000: Can't find FULLTEXT index matching the column list DROP TABLE t1; +CREATE TABLE t1(a TEXT); +INSERT INTO t1 VALUES(' aaaaa aaaa'); +SELECT * FROM t1 WHERE MATCH(a) AGAINST ('"aaaa"' IN BOOLEAN MODE); +a + aaaaa aaaa +DROP TABLE t1; diff --git a/mysql-test/t/fulltext.test b/mysql-test/t/fulltext.test index 1a9a6b578dc..661e93d8d87 100644 --- a/mysql-test/t/fulltext.test +++ b/mysql-test/t/fulltext.test @@ -379,4 +379,12 @@ ALTER TABLE t1 DISABLE KEYS; SELECT * FROM t1 WHERE MATCH(a) AGAINST('test'); DROP TABLE t1; +# +# BUG#11392 - fulltext search bug +# +CREATE TABLE t1(a TEXT); +INSERT INTO t1 VALUES(' aaaaa aaaa'); +SELECT * FROM t1 WHERE MATCH(a) AGAINST ('"aaaa"' IN BOOLEAN MODE); +DROP TABLE t1; + # End of 4.1 tests From b0bc908cbfd15a08a093b4df6e42375a7bb68484 Mon Sep 17 00:00:00 2001 From: unknown Date: Tue, 30 Oct 2007 15:22:52 +0100 Subject: [PATCH 23/36] bug#30630 --- mysql-test/mysql-test-run.pl | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/mysql-test/mysql-test-run.pl b/mysql-test/mysql-test-run.pl index 1ec91d200a5..799a37220cc 100755 --- a/mysql-test/mysql-test-run.pl +++ b/mysql-test/mysql-test-run.pl @@ -3715,6 +3715,13 @@ sub mysqld_arguments ($$$$) { # see BUG#28359 mtr_add_arg($args, "%s--connect-timeout=60", $prefix); + # When mysqld is run by a root user(euid is 0), it will fail + # to start unless we specify what user to run as.

Disabling indexes just sets a flag per non-unique index and does not free the index blocks of the affected indexes. Re-enabling indexes creates new indexes with new blocks. The old blocks remain unused in the index file. Fixed by dropping and re-creating all indexes if non-empty disabled indexes exist when enabling indexes. Dropping all indexes resets the internal end-of-file marker to the end of the index file header. It also clears the root block pointers of every index and clears the deleted blocks chains. This way all blocks are declared as free. myisam/mi_check.c: Bug#4692 - DISABLE/ENABLE KEYS waste a space Added function mi_drop_all_indexes() to support drop of all indexes in case we want to re-enable non-empty disabled indexes. Changed mi_repair(), mi_repair_by_sort(), and mi_repair_parallel() to use the new function instead of duplicate drop index code. mysql-test/r/myisam.result: Bug#4692 - DISABLE/ENABLE KEYS waste a space Added test result. mysql-test/t/myisam.test: Bug#4692 - DISABLE/ENABLE KEYS waste a space Added test. --- myisam/mi_check.c | 224 +++++++++++++++++++++++++++---------- mysql-test/r/myisam.result | 25 +++++ mysql-test/t/myisam.test | 26 +++++ 3 files changed, 218 insertions(+), 57 deletions(-) diff --git a/myisam/mi_check.c b/myisam/mi_check.c index ed0a84e737d..ba308f75d24 100644 --- a/myisam/mi_check.c +++ b/myisam/mi_check.c @@ -1375,6 +1375,139 @@ int chk_data_link(MI_CHECK *param, MI_INFO *info,int extend) } /* chk_data_link */ +/** + @brief Drop all indexes + + @param[in] param check parameters + @param[in] info MI_INFO handle + @param[in] force if to force drop all indexes + + @return status + @retval 0 OK + @retval != 0 Error + + @note + Once allocated, index blocks remain part of the key file forever. + When indexes are disabled, no block is freed.
