NAME
Alien::Package::Rpm - an object that represents a rpm package
DESCRIPTION
This is an object class that represents a rpm package. It is derived
from Alien::Package.
FIELDS
prefixes
Relocatable rpm packages have a prefixes field.
METHODS
checkfile
Detect rpm files by their extension.
install
Install a rpm. If RPMINSTALLOPT is set in the environment, the
options in it are passed to rpm on its command line.
scan
Implement the scan method to read a rpm file.
unpack
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.
prep
Prepare for package building by generating the spec file.
cleantree
Delete the spec file.
build
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.
version
Set/get version.
When retreiving the version, remove any dashes in it.
postinst
postrm
preinst
prerm
Set/get script fields.
When retrieving a value, we have to do some truly 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.
arch
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 internal
form.
