From f7886540120d6c9d564053ee25709f07fd49a784 Mon Sep 17 00:00:00 2001 From: unknown Date: Tue, 25 Sep 2007 12:01:23 +0200 Subject: [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. Before: timeout value: 123 3 timeout value: 122 2 timeout value: 122 2 timeout value: 122 2 timeout value: 123 3 After: timeout value: 127 7 timeout value: 126 6 timeout value: 129 9 timeout value: 139 19 timeout value: 137 17 timeout value: 151 31 timeout value: 130 10 timeout value: 132 12 Index: ndb-work/ndb/src/kernel/blocks/dbtc/DbtcMain.cpp =================================================================== ndb/src/common/util/Makefile.am: BUG#30379 Better randomise time before retry in timeout check (DBTC) ndb/include/util/ndb_rand.h: BUG#30379 Better randomise time before retry in timeout check (DBTC) ndb/src/common/util/ndb_rand.c: BUG#30379 Better randomise time before retry in timeout check (DBTC) ndb/src/kernel/blocks/dbtc/DbtcMain.cpp: BUG#30379 Better randomise time before retry in timeout check (DBTC) --- ndb/include/util/ndb_rand.h | 33 +++++++++++++++++++++++++++ ndb/src/common/util/Makefile.am | 3 ++- ndb/src/common/util/ndb_rand.c | 40 +++++++++++++++++++++++++++++++++ ndb/src/kernel/blocks/dbtc/DbtcMain.cpp | 4 +++- 4 files changed, 78 insertions(+), 2 deletions(-) create mode 100644 ndb/include/util/ndb_rand.h create mode 100644 ndb/src/common/util/ndb_rand.c diff --git a/ndb/include/util/ndb_rand.h b/ndb/include/util/ndb_rand.h new file mode 100644 index 00000000000..1521ca9c4ff --- /dev/null +++ b/ndb/include/util/ndb_rand.h @@ -0,0 +1,33 @@ +/* Copyright (C) 2003 MySQL AB + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; version 2 of the License. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
