Hi! Here is part from a patch that I will push today to MariaDB-5.1-release that fixes so that pbxt compiles on OpenSolaris 5.11. Issues fixed: - lock_multi.test was not updated to latest release main.lock_multi.test and still relied on sleep, which caused random failures. Fixed by merging with main.lock_multi.test - thr_main() was declared in /usr/include/thread.h and caused a name conflict. Fixed by renaming it to thr_main_pbxt() Hope you can add this to pbxt ASAP! Regards, Monty === modified file 'mysql-test/suite/pbxt/r/lock_multi.result' --- mysql-test/suite/pbxt/r/lock_multi.result 2009-04-02 10:03:14 +0000 +++ mysql-test/suite/pbxt/r/lock_multi.result 2010-01-06 12:18:02 +0000 @@ -1,22 +1,4 @@ drop table if exists t1,t2; -create table t1(n int); -insert into t1 values (1); -lock tables t1 write; -update low_priority t1 set n = 4; -select n from t1; -unlock tables; -n -1 -drop table t1; -create table t1(n int); -insert into t1 values (1); -lock tables t1 read; -update low_priority t1 set n = 4; -select n from t1; -unlock tables; -n -1 -drop table t1; create table t1 (a int, b int); create table t2 (c int, d int); insert into t1 values(1,1); @@ -43,6 +25,7 @@ insert t1 select * from t2; drop table t2; ERROR 42S02: Table 'test.t2' doesn't exist drop table t1; +End of 4.1 tests create table t1(a int); lock tables t1 write; show columns from t1; @@ -50,10 +33,10 @@ Field Type Null Key Default Extra a int(11) YES NULL unlock tables; drop table t1; -use mysql; +USE mysql; LOCK TABLES columns_priv WRITE, db WRITE, host WRITE, user WRITE; FLUSH TABLES; -use mysql; +USE mysql; SELECT user.Select_priv FROM user, db WHERE user.user = db.user LIMIT 1; OPTIMIZE TABLES columns_priv, db, host, user; Table Op Msg_type Msg_text @@ -63,7 +46,8 @@ mysql.host optimize status OK mysql.user optimize status OK UNLOCK TABLES; Select_priv -use test; +N +USE test; use test; CREATE TABLE t1 (c1 int); LOCK TABLE t1 WRITE; @@ -90,7 +74,115 @@ DROP DATABASE mysqltest_1; ERROR HY000: Can't drop database 'mysqltest_1'; database doesn't exist create table t1 (f1 int(12) unsigned not null auto_increment, primary key(f1)) engine=innodb; lock tables t1 write; -alter table t1 auto_increment=0; alter table t1 auto_increment=0; alter table t1 auto_increment=0; alter table t1 auto_increment=0; alter table t1 auto_increment=0; // -alter table t1 auto_increment=0; alter table t1 auto_increment=0; alter table t1 auto_increment=0; alter table t1 auto_increment=0; alter table t1 auto_increment=0; // +alter table t1 auto_increment=0; +alter table t1 auto_increment=0; +unlock tables; +drop table t1; +create table t1 (a int); +create table t2 like t1; +# con1 +lock tables t1 write; +# con2 +flush tables with read lock; +# con5 +# global read lock is taken +# con3 +select * from t2 for update; +# waiting for release of read lock +# con4 +# would hang and later cause a deadlock +flush tables t2; +# clean up +unlock tables; +unlock tables; +a +drop table t1,t2; +# +# Lightweight version: +# Ensure that the wait for a GRL is done before opening tables. +# +create table t1 (a int); +create table t2 like t1; +# +# UPDATE +# +# default +flush tables with read lock; +# con1 +update t2 set a = 1; +# default +# statement is waiting for release of read lock +# con2 +flush table t2; +# default +unlock tables; +# con1 +# +# LOCK TABLES ..
