+# BUG#23300: Slow query log on slave does not log slow replicated statements
+#
+# Description:
+#   The slave should log slow queries replicated from master when
+#   --log-slow-slave-statements is used.
+#
+#   Test is implemented as follows:
+#      i) stop slave
+#     ii) On slave, set long_query_time to a small value.
+#     ii) start slave so that long_query_time variable is picked by sql thread
+#    iii) On master, do one short time query and one long time query, on slave
+#         and check that slow query is logged to slow query log but fast query 
+#         is not.
+#     iv) On slave, check that slow queries go into the slow log and fast dont,
+#         when issued through a regular client connection
+#      v) On slave, check that slow queries go into the slow log and fast dont
+#         when we use SET TIMESTAMP= 1 on a regular client connection.
+#     vi) check that when setting slow_query_log= OFF in a connection 'extra2'
+#         prevents logging slow queries in a connection 'extra'
+#
+# OBS: 
+#   This test only runs for statement binlogging format because on row format
+#   slow queries do not get slow query logged. 
+#   Note that due to the sleep() command the insert is written to the binary
+#   log in row format.

+- Set "Oracle and/or its affiliates" as the vendor and copyright owner,
+  accept upgrading from packages showing MySQL or Sun as vendor.
+
+* Fri Feb 05 2010 Joerg Bruehe <joerg.bruehe@sun.com>
+
+- Formatting changes:
+  Have a consistent structure of separator lines and of indentation
+  (8 leading blanks => tab).
+- Introduce the variable "src_dir".
+- Give the environment variables "MYSQL_BUILD_CC(CXX)" precedence
+  over "CC" ("CXX").
+- Drop the old "with_static" argument analysis, this is not supported
+  in 5.1 since ages.
+- Introduce variables to control the handlers individually, as well
+  as other options.
+- Handle the InnoDB plugin using a positive logic: "WITH_INNODB_PLUGIN",
+  the old negative logic ("WITHOUT_INNODB_PLUGIN") was obfuscating.
+- Use the new "--with-plugin" notation for the table handlers.
+- Drop handling "/etc/rc.d/init.d/mysql", the switch to "/etc/init.d/mysql"
+  was done back in 2002 already.
+- Make "--with-zlib-dir=bundled" the default, add an option to disable it.
+- Add missing manual pages to the file list.
+- Improve the runtime check for "libgcc.a", protect it against being tried
+  with the Intel compiler "icc".
