Alien::Package::Rpm - an object that represents a rpm package
This is an object class that represents a rpm package. It is derived from
- Relocatable rpm packages have a prefixes field.
- Detect rpm files by their extension.
- Install a rpm. If RPMINSTALLOPT is set in the environment,
the options in it are passed to rpm on its command line.
- Implement the scan method to read a rpm file.
- Implement the unpack method to unpack a rpm file. This is a
little nasty because it has to handle relocatable rpms and has to do a bit
of permissions fixing as well.
- Prepare for package building by generating the spec
- Delete the spec file.
- Build a rpm. If RPMBUILDOPT is set in the environment, the
options in it are passed to rpm on its command line.
An optional parameter, if passed, can be used to specify the program to use
to build the rpm. It defaults to rpmbuild.
- Set/get version.
When retreiving the version, remove any dashes in it.
- Set/get script fields.
When retrieving a value, we have to do some truely sick mangling. Since
debian/slackware scripts can be anything -- perl programs or binary files
-- and rpm is limited to only shell scripts, we need to encode the files
and add a scrap of shell script to make it unextract and run on the fly.
When setting a value, we do some mangling too. Rpm maintainer scripts are
typically shell scripts, but often lack the leading shebang line. This can
confuse dpkg, so add the shebang if it looks like there is no shebang
magic already in place.
Additionally, it's not uncommon for rpm maintainer scripts to contain
bashisms, which can be triggered when they are ran on systems where
/bin/sh is not bash. To work around this, the shebang line of the scripts
is changed to use bash.
Also, if the rpm is relocatable, the script could refer to
RPM_INSTALL_PREFIX, which is set by rpm at run time. Deal with this by
adding code to the script to set RPM_INSTALL_PREFIX.
- Set/get arch field. When the arch field is set, some
sanitizing is done first to convert it to the debian format used
internally. When it's retrieved it's converted back to rpm form from the
