The problem was that enabling the event scheduler inside a init
file caused the server to crash upon start-up. The crash occurred
because the event scheduler wasn't being initialized before the
commands in the init-file are processed.
The solution is to initialize the event scheduler before the init
file is read. The patch also disables the event scheduler during
bootstrap and makes the bootstrap operation robust in the
presence of background threads.
mysql-test/std_data/init_file.dat:
Add test case for Bug#43587
sql/event_scheduler.cc:
Signal that the thread_count has been decremented.
sql/events.cc:
Disable the event scheduler during bootstrap.
sql/mysql_priv.h:
Export variable.
sql/mysqld.cc:
Initialize the event scheduler before commands are executed.
sql/sql_parse.cc:
Signal that the bootstrap thread is done.
- Starting time of a query sent by bootstrapping wasn't initialized
and starting time defaulted to 0. This later used value by NOW-
item and was translated to 1970-01-01 11:00:00.
- Marketing the time with thd->set_time() before the call to
mysql_parse resolves this issue.
- set_time was refactored to be part of the thd->init_for_queries-
process.
mysql-test/r/init_file.result:
Manual merge from 4.1
mysql-test/std_data/init_file.dat:
Manual merge from 4.1
sql/sql_class.cc:
- Moved set_time into init_for_queries process.
run at startup"
The server returned an error when trying to execute init-file with a
stored procedure that could return multiple result sets to the client.
A stored procedure can return multiple result sets if it contains
PREPARE, SELECT, SHOW and similar statements.
The fix is to set client_capabilites|=CLIENT_MULTI_RESULTS in
sql_parse.cc:handle_bootstrap(). There is no "client" really, so
nothing is ever sent. This makes init-file feature behave consistently:
the prepared statements that can be called directly in the init-file
can be used in a stored procedure too.
Re-committed the patch originally submitted by Per-Erik after review.
mysql-test/Makefile.am:
Fix re-make without make clean.
mysql-test/r/init_connect.result:
Updated results (a test case for Bug#17843)
mysql-test/r/init_file.result:
Updated results (a test case for Bug#17843)
mysql-test/std_data/init_file.dat:
Add test coverage for new features added in 5.0. Note, that what can
be done in init_file is very limited as it does not support any other
delimiter except ';' -- only "one liners" and no multiple statement
procedures. Also, this is executed with a dummy user "boot@", which
calls for the use of DEFINER clause.
mysql-test/t/init_connect.test:
Add test coverage for new features added in 5.0.
mysql-test/t/init_file.test:
Add test coverage for new features added in 5.0 --
stored routines, views, triggers. The actual tests are in
std_data/init_file.dat, here we just check the results and clean up.
sql/sql_class.cc:
Initialize Security_context::priv_host to an empty string:
when executing an init-file, sql_parse.cc:get_default_definer()
will use this for the value of the definer if it's not set in the query.
sql/sql_parse.cc:
Set CLIENT_MULTI_RESULTS in handle_bootstrap(), to make prepared
statements work in stored procedures called from init-file.
mkdir in Makefile, not in configure

sql/ha_ndbcluster.cc:
Change mode to -rw-rw-r--
sql/ha_ndbcluster.h:
Change mode to -rw-rw-r--
BitKeeper/etc/ignore:

mysql-test/std_data/init_file.dat:
add EOL
make a test faster
so it gets picked up by "make dist" and updated init_file test accordingly.
mysql-test/std_data/init_file.dat:
Rename: mysql-test/t/init_file.sql -> mysql-test/std_data/init_file.dat
mysql-test/t/init_file-master.opt:
- moved init file to std_data
mysql-test/t/init_file.test:
- updated info
