 # Revision 1.151  2003/10/03 15:11:03  albertel  
 # - if we fail to fetch an update to the file, don't blow away the old one  
 #   (this was the BUG that blew away that one default.sequence that Matthew  
 #    ended up restoring from data.)  
 #  
 # Revision 1.150  2003/09/30 10:16:06  foxr  
 # Added invocation of apachereload in ReloadApache sub.  
 # This completes the addtion of the reinit functionality.  
 #  
 # Revision 1.149  2003/09/30 09:44:13  foxr  
 # Tested UpdateHosts ability to  
 # - Remove live children for hosts that are no longer in the hosts.tab  
 # - Remove live children for hosts whose IPs have changed in the hosts.tab  
 #  
 # Revision 1.148  2003/09/29 10:09:18  foxr  
 # Put in logic to reinit lond itself (except for apache reload).  I don't believe  
 # this logic works correctly yet, however lond still does everything it used to doso I'll do the commit anyway.  
 #  
 # Revision 1.147  2003/09/23 11:23:31  foxr  
 # Comlplete implementation of reinit functionality.  Must still implement  
 # the actual initialization functionality, but the process can now  
 # receive the request and either invoke the appropriate internal function or  
 # signal the correct lonc.  
 #  
 # Revision 1.146  2003/09/16 10:28:14  foxr  
 # ReinitProcess - decode the process selector and produce the associated pid  
 # filename.  Note: While it is possible to test that valid process selectors are  
 # handled properly I am not able to test that invalid process selectors produce  
 # the appropriate error as lonManage also blocks the use of invalid process selectors.  
 #  
 # Revision 1.145  2003/09/16 10:13:20  foxr  
 # Added ReinitProcess function to oversee the parsing and processing of the  
 # reinit:<process> client request.  
 #  
 # Revision 1.144  2003/09/16 09:47:01  foxr  
 # Added skeletal support for SIGUSR2 (update hosts.tab)  
 #  
 # Revision 1.143  2003/09/15 10:03:52  foxr  
 # Completed and tested code for pushfile.  
 #  
 # Revision 1.142  2003/09/09 20:47:46  www  
 # Permanently store chatroom entries in chatroom.log  
 #  
 # Revision 1.141  2003/09/08 10:32:07  foxr  
 # Added PushFile sub This sub oversees the push of a new configuration table file  
 # Currently supported files are:  
 # - hosts.tab   (transaction pushfile:hosts:contents)  
 # - domain.tab  (transaction pushfile:domain:contents)
