21 $Log: gcm_daemon.php,v $
22 Revision 1.15 2003-09-02 12:48:09 arjen
23 BUGFIX: Secondary indices on log_notification were unique.
24 Additional information in the 'usr' table: 'display_name' and 'email'.
25 Added new issues and services.
27 Revision 1.14 2003/09/01 06:51:07 arjen
28 Accept command argument '-c config' to use an alternate
29 gnucomo configuration.
31 Revision 1.13 2003/08/14 10:22:42 arjen
34 Revision 1.12 2003/08/05 07:46:37 arjen
35 BUGFIX: Print an error message if a parameter does not have
38 Revision 1.11 2003/07/09 07:25:02 arjen
39 Gcm_daemon gathers statistics on parameters, notifications, etc. for all objects.
41 Revision 1.10 2003/03/29 08:33:58 arjen
42 In phpclasses/db.class.php: Added the database connection string as
43 an argument to the function copy_db_class.
44 Fixed the PHP member function db::db_connect(). The Postgres connection
45 string is now passed as an argument to that function.
47 Revision 1.9 2003/02/21 08:37:59 arjen
48 Added new table to the database: log_adv_daemon_email.
