| 7 | # Convienence class for extracting RPMs |
8 | # @BLURB: convenience class for extracting RPMs |
| 8 | # |
|
|
| 9 | # Basically, rpm_src_unpack does: |
|
|
| 10 | # |
|
|
| 11 | # 1. uses rpm_unpack to unpack a rpm file using rpmoffset and cpio |
|
|
| 12 | # 2. if it is a source rpm, it finds all .tar .tar.gz, .tgz, .tbz2, .tar.bz2, |
|
|
| 13 | # .zip, .ZIP and unpacks them using unpack() (with a little hackery) |
|
|
| 14 | # 3. deletes all the unpacked tarballs and zip files from ${WORKDIR} |
|
|
| 15 | # |
|
|
| 16 | # This ebuild now re-defines a utility function called rpm_unpack which |
|
|
| 17 | # basically does what rpm2targz does, except faster. It does not gzip the |
|
|
| 18 | # output tar again but directly extracts to ${WORKDIR} |
|
|
| 19 | # |
|
|
| 20 | # It will autodetect for rpm2cpio (included in app-arch/rpm) and if it exists |
|
|
| 21 | # it will use that instead of the less reliable rpmoffset. This means if a |
|
|
| 22 | # particular rpm cannot be read using rpmoffset, you just need to put : |
|
|
| 23 | # |
|
|
| 24 | # DEPEND="app-arch/rpm" |
|
|
| 25 | # |
|
|
| 26 | # in your ebuild and it will install and use rpm2cpio instead. If you wish |
|
|
| 27 | # to force your ebuild to use rpmoffset in the presence of rpm2cpio, define: |
|
|
| 28 | # |
|
|
| 29 | # USE_RPMOFFSET_ONLY="1" |
