       mod-active - batch processing of ctlinnd newgroup/rmgroup/changegroup


       mod-active [ ctlinnd_command_file ]


       mod-active  is  a perl script that updates the active file based on its
       input lines of ctlinnd newgroup, rmgroup and changegroup commands.   It
       pauses  the  server  briefly while the existing active file is read and
       rewritten, which not only keeps innd from updating the active file  but
       also locks against other instances of mod-active.

       The input to mod-active can come either from one or more files named on
       the command line, or from the standard input.  Typically its  input  is
       the  output  from  the  docheckgroups  or actsync commands.  Every line
       which contains the string "ctlinnd  newgroup",  "ctlinnd  rmgroup",  or
       "ctlinnd  changegroup",  optionally  preceded  by whitespace and/or the
       path to ctlinnd, is noted for the update.  Redundant commands, such  as
       a  newgroup  directive  for  a  group that already exists, are silently
       ignored.  All other lines in the input are also silently ignored.

       After the new active file has  been  generated,  the  existing  one  is
       renamed  to active.old and the new one is moved into place.  The script
       then displays the differences between the two files.

       Any groups that were added to the active file are  also  added  to  the
       active.times file with the string "checkgroups-update".


       Though  innd  is paused while mod-active works, it is not inconceivable
       that there could be a conflict if something else tries  to  update  the
       active  file  during  the  relatively  short  time  that  mod-active is
       working.  The two most realistic ways I can think of for this to happen
       are  either  by  an  administrator  concurrently doing a manual ctlinnd
       command, or by  innd  receiving  a  control  message,  then  mod-active
       pausing  the  server, then the control message handler script that innd
       forked running its own ctlinnd command  while  mod-active  is  working.
       I’ve  been  using  mod-active  regularly for several years, though, and
       never had either problem.
