From afdae2f3b7245b5242ef27ff850365cd4a43dd93 Mon Sep 17 00:00:00 2001 From: unknown Date: Tue, 3 Oct 2006 18:42:59 +0400 Subject: [PATCH 1/2] Patch for BUG#15934: im_daemon_life_cycle fails sporadically. The problem was a race condition in a test case. The fix eliminates the race condition by explicit wait on UNIX socket to start accepting connections. The patch affects only test suite (i.e. does not touch server codebase). mysql-test/mysql-test-run.pl: Expose necessary environment variables. mysql-test/r/im_daemon_life_cycle.result: Update result file. mysql-test/t/im_daemon_life_cycle.imtest: Wait for Instance Manager to start accepting connections after restart. mysql-test/t/wait_for_socket.sh: Helper script: waits for UNIX socket to start accepting connections. --- mysql-test/mysql-test-run.pl | 6 +++ mysql-test/r/im_daemon_life_cycle.result | 1 + mysql-test/t/im_daemon_life_cycle.imtest | 6 +++ mysql-test/t/wait_for_socket.sh | 62 ++++++++++++++++++++++++ 4 files changed, 75 insertions(+) create mode 100755 mysql-test/t/wait_for_socket.sh diff --git a/mysql-test/mysql-test-run.pl b/mysql-test/mysql-test-run.pl index 06dd3864212..41d86944ada 100755 --- a/mysql-test/mysql-test-run.pl +++ b/mysql-test/mysql-test-run.pl @@ -1249,6 +1249,9 @@ sub environment_setup () { $ENV{'IM_PATH_PID'}= $instance_manager->{path_pid}; $ENV{'IM_PATH_ANGEL_PID'}= $instance_manager->{path_angel_pid}; $ENV{'IM_PORT'}= $instance_manager->{port}; + $ENV{'IM_PATH_SOCK'}= $instance_manager->{path_sock}; + $ENV{'IM_USERNAME'}= $instance_manager->{admin_login}; + $ENV{'IM_PASSWORD'}= $instance_manager->{admin_password}; $ENV{'IM_MYSQLD1_SOCK'}= $instance_manager->{instances}->[0]->{path_sock}; $ENV{'IM_MYSQLD1_PORT'}= $instance_manager->{instances}->[0]->{port}; @@ -1257,6 +1260,9 @@ sub environment_setup () { $ENV{'IM_MYSQLD2_PORT'}= $instance_manager->{instances}->[1]->{port}; $ENV{'IM_MYSQLD2_PATH_PID'}=$instance_manager->{instances}->[1]->{path_pid}; + $ENV{'EXE_MYSQL'}= $exe_mysql; + + $ENV{MTR_BUILD_THREAD}= 0 unless $ENV{MTR_BUILD_THREAD}; # Set if not set # We are nice and report a bit about our settings diff --git a/mysql-test/r/im_daemon_life_cycle.result b/mysql-test/r/im_daemon_life_cycle.result index 52a69d98fcf..a0849313b19 100644 --- a/mysql-test/r/im_daemon_life_cycle.result +++ b/mysql-test/r/im_daemon_life_cycle.result @@ -8,6 +8,7 @@ mysqld2 offline Killing the process...

With this change, "CALL p;" is equivalent to "CALL p();". While the SQL spec does not explicitely mandate this syntax, supporting it is needed for practical reasons, for integration with JDBC / ODBC connectors. Also, warnings in the sql/sql_yacc.yy file, which were not reported by Bison 2.1 but are now reported by Bison 2.2, have been fixed. The warning found were: bison -y -p MYSQL -d --debug --verbose sql_yacc.yy sql_yacc.yy:653.9-18: warning: symbol UNLOCK_SYM redeclared sql_yacc.yy:656.9-17: warning: symbol UNTIL_SYM redeclared sql_yacc.yy:658.9-18: warning: symbol UPDATE_SYM redeclared sql_yacc.yy:5169.11-5174.11: warning: unused value: $2 sql_yacc.yy:5208.11-5220.11: warning: unused value: $5 sql_yacc.yy:5221.11-5234.11: warning: unused value: $5 conflicts: 249 shift/reduce "unused value: $2" correspond to the $$=$1 assignment in the 1st {} block in table_ref -> join_table {} {}, which does not procude a result ($$) for the rule but an intermediate $2 value for the action instead. "unused value: $5" are similar, with $$ assignments in {} actions blocks which are not for the final reduce. mysql-test/r/sp.result: New test case for Bug#21462 mysql-test/t/sp.test: New test case for Bug#21462 sql/sql_yacc.yy: "CALL p;" syntax for calling a stored procedure Fixed bison 2.2 warnings. --- mysql-test/r/sp.result | 27 +++++++++++++++++++++++++++ mysql-test/t/sp.test | 33 +++++++++++++++++++++++++++++++++ sql/sql_yacc.yy | 20 +++++++++++--------- 3 files changed, 71 insertions(+), 9 deletions(-) diff --git a/mysql-test/r/sp.result b/mysql-test/r/sp.result index 31aa96ab05d..6e8a609d669 100644 --- a/mysql-test/r/sp.result +++ b/mysql-test/r/sp.result @@ -5470,5 +5470,32 @@ CAD CHF DROP FUNCTION bug21493| DROP TABLE t3,t4| +drop procedure if exists proc_21462_a| +drop procedure if exists proc_21462_b| +create procedure proc_21462_a() +begin +select "Called A"; +end| +create procedure proc_21462_b(x int) +begin +select "Called B"; +end| +call proc_21462_a| +Called A +Called A +call proc_21462_a()| +Called A +Called A +call proc_21462_a(1)| +ERROR 42000: Incorrect number of arguments for PROCEDURE test.proc_21462_a; expected 0, got 1 +call proc_21462_b| +ERROR 42000: Incorrect number of arguments for PROCEDURE test.proc_21462_b; expected 1, got 0 +call proc_21462_b()| +ERROR 42000: Incorrect number of arguments for PROCEDURE test.proc_21462_b; expected 1, got 0 +call proc_21462_b(1)| +Called B +Called B +drop procedure proc_21462_a| +drop procedure proc_21462_b| End of 5.0 tests drop table t1,t2; diff --git a/mysql-test/t/sp.test b/mysql-test/t/sp.test index 87d19baf888..ffbbf56d3ac 100644 --- a/mysql-test/t/sp.test +++ b/mysql-test/t/sp.test @@ -6420,6 +6420,39 @@ SELECT bug21493(Member_ID) FROM t3| DROP FUNCTION bug21493| DROP TABLE t3,t4| +# +# Bug#21462 Stored procedures with no arguments require parenthesis +# + +--disable_warnings +drop procedure if exists proc_21462_a| +drop procedure if exists proc_21462_b| +--enable_warnings + +create procedure proc_21462_a() +begin + select "Called A"; +end| + +create procedure proc_21462_b(x int) +begin + select "Called B"; +end| + +call proc_21462_a| +call proc_21462_a()| +-- error ER_SP_WRONG_NO_OF_ARGS +call proc_21462_a(1)| + +-- error ER_SP_WRONG_NO_OF_ARGS +call proc_21462_b| +-- error ER_SP_WRONG_NO_OF_ARGS +call proc_21462_b()| +call proc_21462_b(1)| + +drop procedure proc_21462_a| +drop procedure proc_21462_b| + --echo End of 5.0 tests diff --git a/sql/sql_yacc.yy b/sql/sql_yacc.yy index cb105d05332..06afbabbba4 100644 --- a/sql/sql_yacc.yy +++ b/sql/sql_yacc.yy @@ -650,11 +650,8 @@ bool my_yyoverflow(short **a, YYSTYPE **b, ulong *yystacksize); %token UNIX_TIMESTAMP %token UNKNOWN_SYM %token UNLOCK_SYM -%token UNLOCK_SYM %token UNSIGNED %token UNTIL_SYM -%token UNTIL_SYM -%token UPDATE_SYM %token UPDATE_SYM %token UPGRADE_SYM %token USAGE @@ -1447,15 +1444,20 @@ call: lex->value_list.empty(); sp_add_used_routine(lex, YYTHD, $2, TYPE_ENUM_PROCEDURE); } - '(' sp_cparam_list ')' {} + opt_sp_cparam_list {} ; /* CALL parameters */ -sp_cparam_list: +opt_sp_cparam_list: /* Empty */ - | sp_cparams + | '(' opt_sp_cparams ')' ; +opt_sp_cparams: + /* Empty */ + | sp_cparams + ; + sp_cparams: sp_cparams ',' expr { @@ -5166,7 +5168,7 @@ when_list2: /* Warning - may return NULL in case of incomplete SELECT */ table_ref: table_factor { $$=$1; } - | join_table { $$=$1; } + | join_table { LEX *lex= Lex; if (!($$= lex->current_select->nest_last_join(lex->thd))) @@ -5208,7 +5210,7 @@ join_table: | table_ref normal_join table_ref ON { - YYERROR_UNLESS($1 && ($$=$3)); + YYERROR_UNLESS($1 && $3); /* Change the current name resolution context to a local context. */ if (push_new_name_resolution_context(YYTHD, $1, $3)) YYABORT; @@ -5223,7 +5225,7 @@ join_table: | table_ref STRAIGHT_JOIN table_factor ON { - YYERROR_UNLESS($1 && ($$=$3)); + YYERROR_UNLESS($1 && $3); /* Change the current name resolution context to a local context. */ if (push_new_name_resolution_context(YYTHD, $1, $3)) YYABORT;
