From f1a1e89f5a16f7b48cbd2b47e9de5d881448fcb4 Mon Sep 17 00:00:00 2001 From: Georgi Kodinov Date: Fri, 17 Oct 2008 13:55:16 +0300 Subject: [PATCH 01/18] Bug #38637: COUNT DISTINCT prevents NULL testing in HAVING clause IS NULL was not checking the correct row in a HAVING context. At the first row of a new group (where the HAVING clause is evaluated) the column and SELECT list references in the HAVING clause should refer to the last row of the previous group and not to the current one. This was not done for IS NULL, because it was using Item::is_null() doesn't have a Item_is_null_result() counterpart to access the data from the last row of the previous group. Note that all the Item::val_xxx() functions (e.g. Item::val_int()) have their _result counterparts (e.g. Item::val_int_result()). Fixed by implementing a is_null_result() (similarly to int_result()) and calling this instead of is_null() column and SELECT list references inside the HAVING clause. --- mysql-test/r/having.result | 7 +++++++ mysql-test/t/having.test | 11 +++++++++++ sql/item.cc | 19 ++++++++++++++++++- sql/item.h | 3 +++ sql/item_func.cc | 9 +++++++++ sql/item_func.h | 1 + 6 files changed, 49 insertions(+), 1 deletion(-) diff --git a/mysql-test/r/having.result b/mysql-test/r/having.result index f113304c767..bc8596100f8 100644 --- a/mysql-test/r/having.result +++ b/mysql-test/r/having.result @@ -424,3 +424,10 @@ select f1 from t1 group by f1 having max(f1)=f1;

Updated MySQL time handling code to react correctly on UTC leap second additions. MySQL functions that return the OS current time, like e.g. CURDATE(), NOW() etc will return :59:59 instead of :59:60 or 59:61. As a result the reader will receive :59:59 for 2 or 3 consecutive seconds during the leap second.

This state was correctly maintained inside the selection of the next partial plan table (in best_extension_by_limited_search()). greedy_search() also moves the current position by adding the last partial match table when there's not enough tables in the partial plan found by best_extension_by_limited_search(). This may require update of the global state variables that describe the current position in the plan if the last table placed by greedy_search is not a top-level join table. Fixed by updating the state after placing the partial plan table in greedy_search() in the same way this is done on entering the best_extension_by_limited_search().

The fix: 1) Introduce a variable "AWK" in some of the BDB shell scripts, 2) search "gawk" and give it precedence over "awk" when assigning a value to the "AWK" variable, fail if neither is found, 3) use that variable when calling an "awk" program with one of the critical scripts. The perfect solution would be to use the "awk" program found by "configure", but we cannot follow that approach because BDB's configuration is handled as a special case before the overall "configure" is run. Because of this, 1) the "configure" result isn't yet available, 2) "configure" will not handle these BDB files. Searching "gawk" is a (not-so-nice) way out. Note that all this need not be perfectly portable, it is needed only when we create a source distribution tarball from a develkopment tree. --- bdb/dist/s_all | 15 +++++++++++++++ bdb/dist/s_include | 6 +++--- bdb/dist/s_recover | 2 +- bdb/dist/s_rpc | 2 +- 4 files changed, 20 insertions(+), 5 deletions(-) diff --git a/bdb/dist/s_all b/bdb/dist/s_all index 132017def3c..97ce572a4ae 100644 --- a/bdb/dist/s_all +++ b/bdb/dist/s_all @@ -1,6 +1,21 @@ #!/bin/sh - # $Id: s_all,v 1.10 2001/08/04 14:01:44 bostic Exp $ +# Search an AWK program, use GNU awk if available +for x in gawk awk ; do + if type $x; then + AWK=$x + break + fi +done + +if test -z "$AWK"; then + echo 'No AWK program found' + exit 1 +fi +export AWK +# end of AWK search + sh s_dir #sh s_perm # permissions. diff --git a/bdb/dist/s_include b/bdb/dist/s_include index 878b4a38af1..5cb3a666dc0 100755 --- a/bdb/dist/s_include +++ b/bdb/dist/s_include @@ -79,7 +79,7 @@ for i in db btree clib common dbreg env fileops hash hmac \ [ $i = os ] && f="$f ../os_win32/*.c" [ $i = rpc_server ] && f="../$i/c/*.c" [ $i = crypto ] && f="../$i/*.c ../$i/*/*.c" - awk -f gen_inc.awk \ + $AWK -f gen_inc.awk \ -v db_version_unique_name=$DB_VERSION_UNIQUE_NAME \ -v e_dfile=$e_dfile \ -v e_pfile=$e_pfile \ @@ -97,7 +97,7 @@ done # files. for i in dbm hsearch; do f="../$i/*.c" - awk -f gen_inc.awk \ + $AWK -f gen_inc.awk \ -v db_version_unique_name=$DB_VERSION_UNIQUE_NAME \ -v e_dfile=$e_dfile \ -v e_pfile=$e_pfile \ @@ -142,7 +142,7 @@ head space defonly _DB_EXT_185_DEF_IN_ > $e_dfile head space _DB_EXT_185_PROT_IN_ > $e_pfile f="../db185/*.c" -awk -f gen_inc.awk \ +$AWK -f gen_inc.awk \ -v db_version_unique_name=$DB_VERSION_UNIQUE_NAME \ -v e_dfile=$e_dfile \ -v e_pfile=$e_pfile \ diff --git a/bdb/dist/s_recover b/bdb/dist/s_recover index fc2e160c083..f6d2ad33e5a 100755 --- a/bdb/dist/s_recover +++ b/bdb/dist/s_recover @@ -45,7 +45,7 @@ cmp $loglist $f > /dev/null 2>&1 || for i in db dbreg btree fileops hash qam txn; do for f in ../$i/*.src; do subsystem=`basename $f .src` - awk -f gen_rec.awk \ + $AWK -f gen_rec.awk \ -v source_file=$source \ -v header_file=$header \ -v template_file=$template < $f diff --git a/bdb/dist/s_rpc b/bdb/dist/s_rpc index cdafa669d85..f9495ec121f 100644 --- a/bdb/dist/s_rpc +++ b/bdb/dist/s_rpc @@ -43,7 +43,7 @@ rm -f $client_file \ xidsize=\ `awk '/^#define/ { if ($2 == "DB_XIDDATASIZE") { print $3 }}' $dbinc_file` -awk -f gen_rpc.awk \ +$AWK -f gen_rpc.awk \ -v major=$DB_VERSION_MAJOR \ -v minor=$DB_VERSION_MINOR \ -v xidsize=$xidsize \ From 918a0381655a5b34f3ac8a976bb53137bd1ff209 Mon Sep 17 00:00:00 2001 From: Davi Arnaut Date: Tue, 13 Jan 2009 20:07:06 -0200 Subject: [PATCH 14/18] Bug#36326: nested transaction and select The problem is that the query cache stores packets containing the server status of the time when the cached statement was run. This might lead to a wrong transaction status in the client side if a statement is cached during a transaction and is later served outside a transaction context (and vice-versa). The solution is to take into account the transaction status when storing in and serving from the query cache. --- mysql-test/r/innodb_cache.result | 10 +++--- mysql-test/r/query_cache.result | 51 +++++++++++++++++++++++++++ mysql-test/t/query_cache.test | 27 ++++++++++++++ sql/mysql_priv.h | 2 ++ sql/sql_cache.cc | 17 ++++++--- tests/mysql_client_test.c | 60 ++++++++++++++++++++++++++++++++ 6 files changed, 158 insertions(+), 9 deletions(-) diff --git a/mysql-test/r/innodb_cache.result b/mysql-test/r/innodb_cache.result index 5e8611655a2..36fa3c5c352 100644 --- a/mysql-test/r/innodb_cache.result +++ b/mysql-test/r/innodb_cache.result @@ -66,10 +66,10 @@ a 2 show status like "Qcache_queries_in_cache";

The solution is to always discard the caching of a query that failed to send its results to the associated client. --- mysql-test/r/query_cache_notembedded.result | 16 +++++++++++ mysql-test/t/query_cache_notembedded.test | 31 +++++++++++++++++++++ sql/sql_cache.cc | 7 ++++- 3 files changed, 53 insertions(+), 1 deletion(-) diff --git a/mysql-test/r/query_cache_notembedded.result b/mysql-test/r/query_cache_notembedded.result index 8e5df012cfb..bf582bfaec6 100644 --- a/mysql-test/r/query_cache_notembedded.result +++ b/mysql-test/r/query_cache_notembedded.result @@ -345,3 +345,19 @@ id drop table t1; drop function f1; set GLOBAL query_cache_size=0; +DROP TABLE IF EXISTS t1; +FLUSH STATUS; +SET GLOBAL query_cache_size=1048576; +CREATE TABLE t1 (a INT); +INSERT INTO t1 VALUES (1),(2),(3),(4),(5); +SHOW STATUS LIKE 'Qcache_queries_in_cache'; +Variable_name Value +Qcache_queries_in_cache 0 +LOCK TABLES t1 WRITE; +SELECT * FROM t1; +UNLOCK TABLES; +SHOW STATUS LIKE 'Qcache_queries_in_cache'; +Variable_name Value +Qcache_queries_in_cache 0 +DROP TABLE t1; +SET GLOBAL query_cache_size= default; diff --git a/mysql-test/t/query_cache_notembedded.test b/mysql-test/t/query_cache_notembedded.test index a4f4144d9c6..c427e0d1afc 100644 --- a/mysql-test/t/query_cache_notembedded.test +++ b/mysql-test/t/query_cache_notembedded.test @@ -222,3 +222,34 @@ disconnect con2; connection default; set GLOBAL query_cache_size=0; + +# +# Bug#40264: Aborted cached query causes query to hang indefinitely on next cache hit +# + +--disable_warnings +DROP TABLE IF EXISTS t1; +--enable_warnings + +FLUSH STATUS; +SET GLOBAL query_cache_size=1048576; +CREATE TABLE t1 (a INT); +INSERT INTO t1 VALUES (1),(2),(3),(4),(5); +SHOW STATUS LIKE 'Qcache_queries_in_cache'; +LOCK TABLES t1 WRITE; +connect(con1,localhost,root,,); +--send SELECT * FROM t1 +connection default; +let $show_type= open tables where `table`='t1' and in_use=2; +let $show_pattern= '%t1%2%'; +--source include/wait_show_pattern.inc +dirty_close con1; +UNLOCK TABLES; +let $show_type= open tables where `table`='t1' and in_use=0; +let $show_pattern= '%t1%0%'; +--source include/wait_show_pattern.inc +SHOW STATUS LIKE 'Qcache_queries_in_cache'; +DROP TABLE t1; +SET GLOBAL query_cache_size= default; + +# End of 5.0 tests diff --git a/sql/sql_cache.cc b/sql/sql_cache.cc index 4a521d83192..b55fa148e24 100644 --- a/sql/sql_cache.cc +++ b/sql/sql_cache.cc @@ -710,7 +710,12 @@ void query_cache_end_of_result(THD *thd) if (thd->net.query_cache_query == 0) DBUG_VOID_RETURN; - if (thd->killed) + /* + Check if the NET layer raised a unreported error -- my_error() and + as a consequence query_cache_abort() haven't been called.
