6.1 CVS to Pastwatch Conversion

Pastwatch can translate an existing CVS repository and import it into a new Pastwatch project with the cvs2past command.

6.1.1 Required Perl Modules

cvs2past uses the Date::Calc Perl module. If you run cvs2past and it outputs an error message like this:

     % cvs2past 
     Can't locate Date/Calc.pm in @INC (@INC contains:
     /usr/local/lib/perl5/site_perl/5.6.1 /usr/local/lib/perl5/site_perl
     /usr/local/lib/perl5/5.8.5/BSDPAN /usr/local/lib/perl5/5.8.5/mach
     /usr/local/lib/perl5/5.8.5 .) at /usr/local/bin/cvs2past line 16.  BEGIN
     failed--compilation aborted at /usr/local/bin/cvs2past line 16.

then you will need to install Date::Calc. To install Date::Calc run the following commands on your system as root, and answer the configuration questions Perl asks.

     perl -MCPAN -e 'install Date::Calc'

Afterwards, Date::Calc should be installed on your system. Now, running cvs2past should result in usage information.

     % cvs2past 
     cvs2past.pl cvsroot cvsmodule pastmodule projname username

6.1.2 Using cvs2past

cvs2past reads a module from an existing CVS repository and creates a new Pastwatch project that contains all the files, commits and branches from the CVS module.

During translation, cvs2past creates a new Pastwatch project, and a new project member key. The full syntax for cvs2past is:

     cvs2past <cvsroot> <cvsmodule> <pastmodule> <projname> <username>

cvs2past outputs a lot of messages during translation. It is safe to ignore these messages unless cvs2past fails during translation.
