MySQL Bugs: #1643: mysqld does not properly register itself as a service

Bug #1643	mysqld does not properly register itself as a service
Submitted:	24 Oct 2003 7:58	Modified:	11 Dec 2003 17:51
Reporter:	Gilles Levreau
Status:	Closed
Category:	Server	Severity:	S2 (Serious)
Version:	4.0.15	OS:	Microsoft Windows (windows 2000)
Assigned to:	Bugs System	Target Version:

Description:
The way the server is registered as a service has been changed in 4.0.15 and does it
incorrectly.

When the service is started, it expects the last argument to the program to be
the service name. However, when mysqld registers itself to the Service Control Manager,
it omits that service name in the command to call to start the service. Only the
executable path and the option is in the command.

When mysql service is started, it does not recognize it has to start as a service, hangs,
and abort.

How to repeat:
- open console
- cd to mysql bin directory
- mysqld-nt --install mysql --defaults-file="<my-defaults-file>"
- net start mysql

It hangs and after a while prints an error message reading the server could not be
started.

Suggested fix:
In version 4.0.15, this bug can be fixed by adding these lines to sql/mysqld.cpp, line
2570 (in default_service_handling(), after extra_opt has been added to the command):

  /* Add service name at end of command */
  *pos++= ' ';
  pos = strxnmov(pos, (uint) (end-pos), "\"", servicename, "\"", NullS);

Workaround, in the meantime:
- open the registry editor (regedit), go to the key
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\<your mysql service name>

- edit the subkey 'ImagePath' and add the service name at the end of the command
(with a space before it).

- start the service

Verified in 4.0.16.  With additional options --install is not appending the service name.
