    7: install_web_site_cronjob - maintain install.lon-capa.org web-site every day

    9: =head1 DESCRIPTION
   10: 
   11: This is a file that runs periodically on B<install.lon-capa.org>.
   12: 
   13: This file should be run by the 'loninst' user and be part of
   14: the 'loninst' crontab entries (to view loninst crontab, login
   15: as loninst and crontab C<-l>; to edit loninst crontab, login as
   16: loninst and crontab C<-e>).
   17: 
   18: This file should be on the B<install.lon-capa.org> filesystem as
   19: F</home/loninst/auto/install_web_site_cronjob>.
   20: 
   21: The current 'loninst' crontab entry is:
   22: 
   23: 13 16 * * *    /home/loninst/auto/install_web_site_cronjob
   24: 
   25: The main goal of B<install_web_site_cronjob> is to periodically produce the
   26: unstable tarball needed for LON-CAPA installation.
   27: 
   28: A secondary yet important function of B<install_web_site_cronjob> is that it
   29: also refreshes the documentation present on the install.lon-capa.org
   30: web site.
   31: 
   32: This documentation is refreshed based on a file located inside
   33: F</home/loninst/public_html/versions>.  This file is named
   34: F<LATEST-IS-VERSIONNUMBER>, where
   35: I<VERSIONNUMBER> is the latest stable release of loncapa (e.g. 0.4 or 0.6.1).
   36: The F<LATEST-IS-VERSIONNUMBER> file contains a string
   37: that is used to date the release of the current stable version.
   38: 
   39: The coding of this script is a strange brew of shell commands
   40: with perl.

   47: # --------------------------------------------- Making the tarball distribution
   48: 
   49: # In an ideal world, this tarball distribution would be always generated with
   50: # the "make tardist" command.  But instead, unstable is now defined as
   51: # "all the gunk we have been working on", whereas the 
   52: # "make tardist" command means a "carefully inventoried selection of gunk".
   53: #`cd /home/loninst/auto; export CVS_PASSFILE=/home/loninst/.cvspass; export CVSROOT=:pserver:scott\@localhost:/home/cvs; rm -Rf loncapa/[C][^V]*; rm -Rf loncapa/[^C]*; cvs -Q co loncapa; cd loncapa/loncom/build; make build 2>/dev/null; make tardist;`;
   54: 
   55: # The real world.  Just give them all the gunk for the unstable distribution.
   56: `cd /home/loninst/auto; export CVS_PASSFILE=/home/loninst/.cvspass; export CVSROOT=:pserver:scott\@localhost:/home/cvs; rm -Rf loncapa-unstable; rm -Rf loncapa; cvs -Q export -r HEAD loncapa;`;
   57: 
   58: # Generate a README file that advises them about dealing with the gunk.

   63: print(OUT `date`);
   64: print(OUT <<END);
   65: 
   66: To generate an installable tarball distribution from this file, you can
   67: execute the following commands:
   68: cd loncom/build
   69: make tardist
   70: 
   71: Note that the installable tarball distribution (the 'tardist' target)
   72: is what encapsulates the stable releases of the LON-CAPA software (as
   73: well as ensuring that LON-CAPA's distributability does not rely solely on
   74: CVS software).
   75: 
   76: END
   77: print(OUT <<END);
   78: An alternative Makefile command sequence is:
   79: cd loncom/build
   80: make build
   81: make install
   82: 
   83: For more information on Makefile targets, you can just enter the following
   84: commands:
   85: cd loncom/build
   86: make help
   87: 
   88: Finally, if you encounter any problems, be sure to enter them
   89: into the bug database http://bugs.lon-capa.org/ or, alternatively,
   90: discuss them on one of the mailing lists available at
   91: http://mail.lon-capa.org/.
