Re: [Maria-developers] safe patches to backport -- pool-of-threads
by Michael Widenius 20 Mar '09

Hi! Sorry for replying this 'off-thread', but I was not by some strange reason subscribed to the maria-developers list :( MARK CALLAGHAN writes: mark> One of the features listed here mark> http://askmonty.org/wiki/index.php/MariaDB_versus_MySQL as a potential mark> backport is support for pool-of-threads. I am not sure how safe this mark> feature is today. mark> mark> http://mysqlha.blogspot.com/2009/01/no-new-global-mutexes-and-how-to-make.h… mark> describes some of the problems that might cause a server to hang when mark> pool-of-threads is used. The main port of the pool-of-threads code has been in extensive use by a high performance MySQL customer for a long time and, within their limits, it has given them a lot of extra performance. To be fair, the above customer is using a scheduler that is using getport instead of libevent. I am considering to add also getport support to the scheduler.cc in MariaDB, even if this only gives higher performance on Solaris. The patch has it's problems and is not complete, but for certain workloads and configurations it can definitely save the day. One example is if your application needs 200,000 connected users. One of the biggest problem with pool-of-threads is that when you run out of threads you are stuck as you can't see what's going on and you can connect and kill things. The extra-port options fixes that. It also allows you to mix pool-of-threads and one-thread-per-connection in an easy way. It would have been better to make this a connection option, but because connections are also handled by the thread pool, when you run with pool-of-threads, this doesn't work as if all worker threads are occupied the connection will never go trough. Adding another pool for connection would require so much new work that it wouldn't be safe for MariaDB 5.1. For MariaDB 5.2 we should consider looking at adding another thread pool for connections and making the scheduler a connection option. Drizzle is by default using pool-of-threads, so the code gets more tested every day. mark> http://bugs.mysql.com/bug.php?id=42288 describes the performance mark> overhead of pool-of-threads. The overhead is significant for workloads mark> with fast queries such as sysbench. Brian/Drizzle is, as far as I know, trying to benchmark the original getevent port code and the libevent code to find out how things really stands. Brian suspect that there may a problem in libevent that needs to be fixed and he has someone looking into it. When they or we have fixed it, we will collaborate to ensure both projects works properly. mark> I think that pool-of-threads needs a lot of work before it can be mark> considered safe. We backported this to our 5.0 branch at work and have mark> begun to search for fixes. At least pool-of-threads is not default in MariaDB and you have to turn it explicitely one if you want to use it; This makes it reasonable safe to include into MariaDB 5.1 at this point as old user will not be affected at all by it and new users trying it can do that as long as they are aware of the limitations. Regards, Monty

[Maria-developers] Launchpad repoistories upgraded, bzr version 1.9 now required
by Kristian Nielsen 20 Mar '09

20 Mar '09

This morning I finished upgrading our three maria repositories at launchpad to repository format 1.9: lp:maria lp:maria/5.2 lp:maria/6.0 There should be no need to re-branch from launchpad or make any other changes to local trees or branches. However, I believe it will now be necessary to use bzr of at least version 1.9 to access the repositories on launchpad. It is recommended, but not required, to upgrade local shared repositores and branches with bzr upgrade --1.9 to get the following benefits 1. Stacked branches, which allows pushing private clones to lp:~USER/maria/xxx with only having to upload changes to main trees, for me pushing such a private branch now takes only ~30 seconds. 2. General faster operation of bzr in my experience (eg bzr log 10x faster). - Kristian.

#At lp:maria 2684 knielsen(a)knielsen-hq.org 2009-03-17 BUG#43418: MTR2: does not notice a memory leak occuring at shutdown of mysqld w/ --valgrind Problem was that mysql-test-run.pl sometimes skipped parsing part of the error log, and sometimes shutdown mysqld with kill -9, preventing tools like Valgrind and safemalloc from outputting memory leak check in the error logs. Fixed by - Stopping mysqld servers gracefully rather than kill -9 when warnings are being checked. - After stopping mysqld servers, do an additional parse of the error log to check for any warnings generated during shutdown. - Fix error log parsing to be careful not to skip parsing part of the file, by keeping track of previous file position rather than relying on mark_log markers. - Workers report warnings during shutdown to the master process with a new packet 'WARNINGS' which includes a list of names of test that might have caused the problem (could be any test run since last server start). - Fail entire test suite if warnings are found. Also fixed home-brewed and broken serialization in My::Test to use the standard Storable serializer. modified: mysql-test/lib/My/Test.pm mysql-test/mysql-test-run.pl === modified file 'mysql-test/lib/My/Test.pm' --- a/mysql-test/lib/My/Test.pm 2008-11-14 10:49:12 +0000 +++ b/mysql-test/lib/My/Test.pm 2009-03-17 08:23:05 +0000 @@ -9,6 +9,7 @@ package My::Test; use strict; use warnings; use Carp; +use Storable(); sub new { @@ -30,18 +31,6 @@ sub key { } -sub _encode { - my ($value)= @_; - $value =~ s/([|\\\x{0a}\x{0d}])/sprintf('\%02X', ord($1))/eg; - return $value; -} - -sub _decode { - my ($value)= @_; - $value =~ s/\\([0-9a-fA-F]{2})/chr(hex($1))/ge; - return $value; -} - sub is_failed { my ($self)= @_; my $result= $self->{result}; @@ -58,66 +47,22 @@ sub write_test { # Give the test a unique key before serializing it $test->{key}= "$test" unless defined $test->{key}; - print $sock $header, "\n"; - while ((my ($key, $value)) = each(%$test)) { - print $sock $key, "= "; - if (ref $value eq "ARRAY") { - print $sock "[", _encode(join(", ", @$value)), "]"; - } else { - print $sock _encode($value); - } - print $sock "\n"; - } - print $sock "\n"; + my $serialized= Storable::freeze($test); + $serialized =~ s/([\x0d\x0a\\])/sprintf("\\%02x", ord($1))/eg; + print $sock $header, "\n", $serialized, "\n"; } sub read_test { my ($sock)= @_; - my $test= My::Test->new(); - # Read the : separated key value pairs until a - # single newline on it's own line - my $line; - while (defined($line= <$sock>)) { - # List is terminated by newline on it's own - if ($line eq "\n") { - # Correctly terminated reply - # print "Got newline\n"; - last; - } - chomp($line); - - # Split key/value on the first "=" - my ($key, $value)= split("= ", $line, 2); - - if ($value =~ /^\[(.*)\]/){ - my @values= split(", ", _decode($1)); - push(@{$test->{$key}}, @values); - } - else - { - $test->{$key}= _decode($value); - } - } + my $serialized= <$sock>; + chomp($serialized); + $serialized =~ s/\\([0-9a-fA-F]{2})/chr(hex($1))/eg; + my $test= Storable::thaw($serialized); + die "wrong class (hack attempt?)" + unless ref($test) eq 'My::Test'; return $test; } -sub print_test { - my ($self)= @_; - - print "[", $self->{name}, "]", "\n"; - while ((my ($key, $value)) = each(%$self)) { - print " ", $key, "= "; - if (ref $value eq "ARRAY") { - print "[", join(", ", @$value), "]"; - } else { - print $value; - } - print "\n"; - } - print "\n"; -} - - 1; === modified file 'mysql-test/mysql-test-run.pl' --- a/mysql-test/mysql-test-run.pl 2009-03-12 22:27:35 +0000 +++ b/mysql-test/mysql-test-run.pl 2009-03-17 08:23:05 +0000 @@ -357,7 +357,7 @@ sub main { mtr_print_thick_line(); mtr_print_header(); - my $completed= run_test_server($server, $tests, $opt_parallel); + my ($completed, $fail)= run_test_server($server, $tests, $opt_parallel); # Send Ctrl-C to any children still running kill("INT", keys(%children)); @@ -393,6 +393,10 @@ sub main { mtr_error("Not all tests completed"); } + if ($fail) { + mtr_error("Test suite failure."); + } + mtr_print_line(); if ( $opt_gcov ) { @@ -412,6 +416,7 @@ sub run_test_server ($$$) { my $num_saved_cores= 0; # Number of core files saved in vardir/log/ so far. my $num_saved_datadir= 0; # Number of datadirs saved in vardir/log/ so far. my $num_failed_test= 0; # Number of tests failed so far + my $test_failure= 0; # Scheduler variables my $max_ndb= $childs / 2; @@ -445,7 +450,7 @@ sub run_test_server ($$$) { $s->remove($sock); if (--$childs == 0){ $suite_timeout_proc->kill(); - return $completed; + return ($completed, $test_failure); } next; } @@ -509,18 +514,19 @@ sub run_test_server ($$$) { } $num_saved_datadir++; + $test_failure= 1; if ( !$opt_force ) { # Test has failed, force is off $suite_timeout_proc->kill(); push(@$completed, $result); - return $completed; + return ($completed, 1); } elsif ($opt_max_test_fail > 0 and $num_failed_test >= $opt_max_test_fail) { $suite_timeout_proc->kill(); mtr_report("Too many tests($num_failed_test) failed!", "Terminating..."); - return undef; + return (undef, 1); } $num_failed_test++; } @@ -571,7 +577,18 @@ sub run_test_server ($$$) { elsif ($line eq 'START'){ ; # Send first test } - else { + elsif ($line eq 'WARNINGS'){ + my $fake_test= My::Test::read_test($sock); + my $test_list= join (" ", @{$fake_test->{testnames}}); + mtr_report("***Warnings generated in error logs during shutdown ". + "after running tests: $test_list"); + $test_failure= 1; + if ( !$opt_force ) { + # Test failure due to warnings, force is off + $suite_timeout_proc->kill(); + return ($completed, 1); + } + } else { mtr_error("Unknown response: '$line' from client"); } @@ -649,7 +666,7 @@ sub run_test_server ($$$) { if ( ! $suite_timeout_proc->wait_one(0) ) { mtr_report("Test suite timeout!

#At lp:maria 2685 knielsen(a)knielsen-hq.org 2009-03-18 Add testing of extra port for pool-of-threads. The additional test uses up all threads in the pool with SELECT SLEEP(), and tests that this makes normal connections block, but connections on the extra port still work. Also test connection limit on extra port with and without pool-of-threads enabled. Add --connect-timeout option to mysqltest program. Add facility for --extra-port option to ConfigFactory.
