      Packaging the software from CVS onto a machine file system requires many things: -

        -
      • documenting every component of the software, -
      • handling CVS source to file system target information -
      • handling (according to a hierarchical scheme of grouping) file -ownership and permissions, -
      • handling (according to a hierarchical scheme of grouping) directory -ownership and permissions, -
      • handling symbolic links -
      • providing for multiple options of installation targets -(RedHat versus Debian for instance), -
      • providing for different file ownerships and permissions to apply -to the same file, -
      • allowing system software documentation to be automatically generated -(see information on "make html"), -
      • providing information in an easily adjustable form as new demands -are made on the software packaging system, -
      • providing software package information (for RPM), -
      • having information in a format that allows for troubleshooting -the current status of the machine file system, -
      • allow for changes to the structure of the CVS repository, -
      • and something that is simple enough for any one to immediately work with, -without having to learn specifics (or hidden traps) of complicated Makefile's -or a new macro language (m4?). -

      I looked into, and tried, different ways of accomplishing the above including automake and recursive make. The automake system seemed quite complicated (and needlessly so in terms of this project since, by and large, it works to coordinate many different types of build/compilation parameters -whereas we are more concerned with installation parameters). Recursive make -has significant deficiencies in the sense that not all the information +whereas we are more concerned with installation parameters). The other +alternative, recursive make, +has significant deficiencies since not all the information is kept in one place, and there are significant levels of dependency between all the things that must be done to keep software packaging up to date.

Complicating -matters was, at the time, it was unclear as to what categories + +"Recursive Make Considered Harmful" by Peter Miller. Other complications +were that, at the time, it was unclear as to what categories of software files we had, and whether or not the directory structure of CVS would remain constant.

      +

      +If you take time to look at loncapafiles.lpml +(and perhaps run the make HTML command) you will find that the organizing information according to the markup -syntax in loncapafiles.html is simple. Simple is good. -

      -

As with any parser however, I remain paranoid. -

      -

      -My regrets with the current system is that parse.pl is -slow (can take 1 minute to run) and includes a few tidbits of code, -specific to the make process, that probably should be in -loncom/build/Makefile. Additionally, loncapafiles.html -should have a DTD and all those other good SGML-ish things (and parsing -should be done with a real SGML-derived parser). -

      -On the plus side, the parse.pl-loncapafiles.html -combination has been working very efficiently and error-free. -

      Configurable files versus non-configurable files

      -Machine-specific information is the difference -

      +

      +

      +Finally, some notes on the development. +lpml_parse.pl is very fast and styled after a state-based SAX-like +approach. I do eventually want to use a real XML/XSLT approach, however +I hesitate to make everyone everywhere install something like +XML::Xalan. +Also note that loncapafiles.lpml has a +DTD (loncom/build/lpml.dtd) against which it is valid. +I would also like to use more ENTITY's inside lpml.dtd but currently +the perl XML modules available at CPAN do not digest complex ENTITY's that +well. +

      +

      +The lpml_parse.pl-loncapafiles.lpml +combination has been highly efficient and error-free. +

      +
    11. +

      Configurable files versus non-configurable files

      +

      +Machine-specific information is the difference +

      +

      The current list of configurable files for the LON-CAPA system is -/etc/httpd/access.conf, /etc/smb.conf, /etc/ntp.conf, /etc/krb.conf, -/etc/atalk/config, /etc/ntp/step-tickers, -/home/httpd/html/res/adm/includes/copyright.tab, -/home/httpd/html/res/adm/includes/un_keyword.tab, -/home/httpd/hosts.tab, and -/home/httpd/spare.tab. -

      +/etc/httpd/conf/loncapa.conf, +/etc/ntp.conf, +/etc/krb.conf, +/etc/ntp/step-tickers, +/home/httpd/html/res/adm/includes/copyright.tab, +/home/httpd/html/res/adm/includes/un_keyword.tab, +/home/httpd/hosts.tab, and +/home/httpd/spare.tab. +

      +

      All of these configurable files contain machine-specific information. -For instance, the LON-CAPA system relies on unique host IDs such +For instance, the overall LON-CAPA system relies on unique host IDs such as msua3, s1, s2, msul1, and 103a1 (specified as a "PerlSetVar lonHostID" -field within /etc/httpd/access.conf). +field within /etc/httpd/conf/loncapa.conf). Non-configurable files simply do NOT have machine-specific information. -The impact on updating software -

      -What this means in terms of software updating is that -

        -
      • non-configurable files can be simply overwritten with newer versions -(without "anything" else to worry about), -
      • and configurable files must follow these steps to be safely overwritten -
          -
        1. have their machine specific information saved, -
        2. be overwritten, and then -

      Configuration files are installed during this step. This means -that files such as /etc/httpd/access.conf, /etc/smb.conf, /etc/atalk/config, -/home/httpd/html/res/adm/includes/copyright.tab, and -/home/httpd/spare.tab are overwritten. Before being overwritten, +that files such as /etc/httpd/conf/loncapa.conf, +/home/httpd/html/res/adm/includes/copyright.tab, and +/home/httpd/spare.tab are overwritten. Before being overwritten, a backup copy is made though. Information is read out of these backup copies and restored to the new files by the -loncaparestoreconfigurations script. To ensure that +loncaparestoreconfigurations script. To ensure that new file permissions and ownerships are installed, a final set of -chown and chmod commands are called for each of +chown and chmod commands are called for each of the configuration files. -

      +

      If you are truly paranoid, you can just make the -Makefile.configinstall file and then save, copy, +Makefile.configinstall file and then save, copy, and restore all the configuration values yourself. -loncaparestoreconfigurations is pretty smart though, has yet to -fail, and besides, a backup copy is always made (time-stamped so that backup -copies are not overwritten). -

      Building RPMs (make RPM)

      -Commands - -
      -cd loncom/build
      -rm -Rf BinaryRoot (or alternatively, "make clean")
      -make RPM
      -   (to subsequently install, you can type commands like
      -       "rpm -Uvh --force LON-CAPA-base-3.1-1.i386.rpm")
      -
      -
      -

      -WARNING!!!!!!!!!!!!!! -

      -Never never never never never manually install the -LON-CAPA-setup-3.1-1.i386.rpm. This RPM is meant to only be -installed by the CD installation process (it wipes out -the existing /etc/passwd file). -

      Building RPMs (make RPM)

      +

      +LON-CAPA is currently installed through "intelligent tarballs". +What I am describing now is part of an earlier (and perhaps future) effort +involving RPMs. +

      +

      +Commands +

      +

      +cd loncom/build
      +rm -Rf BinaryRoot (or alternatively, "make clean")
      +make RPM
      +(to subsequently install, you can type commands like +"rpm -Uvh --force LON-CAPA-base-3.1-1.i386.rpm") +

      +

      +Configuration files +

      +

      Configuration files are automatically saved with the file suffix -".rpmsave". So /etc/httpd/conf/access.conf is saved as -/etc/httpd/conf/access.conf.rpmsave. You can restore -the machine-specific configuration information by running -the /usr/sbin/loncaparestoreconfigurations. However, -a warning is important here. If you install an RPM twice -without restoring your configuration, you will overwrite the +".rpmsave". So /etc/httpd/conf/loncapa.conf is saved as +/etc/httpd/conf/loncapa.conf.rpmsave. +The loncaparestoreconfigurations script should work to restore +configurations in this case. However, please note that if you install an RPM +twice without restoring your configuration, you will overwrite the ".rpmsave" files. -

      +loncom/build/make_rpm.pl (also available at +CPAN) is robust (tested over the span of months) and, unlike other automated RPM-builders, cleanly builds new RPMs without any after-effect of temporary files left -on the system. (On the negative side, there are a number of -LON-CAPA specific customizations inside make_rpm.pl which, for -the sake of reusability, should eventually be removed). Two new RPMs -are generated: LON-CAPA-base-3.1-1.i386 and LON-CAPA-setup-3.1-1.i386.rpm -(again, never manually install LON-CAPA-setup-3.1-1.i386.rpm). -
