Arch Linux

Oops, I phrased the last line wrong. Should say: Even if SuSE aren't making valid RPMs, rpmextract 0-2 is broken because rpmextract 0-1 could handle them ;)

So, I recommend reverting back.

rpmextract 0-2 uses bsdtar, so it's bsdtar that cannot extract some broken rpms

never change a working script :D

$ rpmextract.sh wine-snapshot-0.9.55.20080219-11.1.i586.rpm
gzip: stdin: not in gzip format
cpio: premature end of archive

I'm sorry, but that doesn't indicate working to me- it just indicates a different kind of failure.

Can you expand on your generalization here? You file the bug as 'SuSE RPMs' and yet only tried one.

Don't confuse success and failure. Success is extracting all the files properly with a return code of 0. That's what rpmextract 0-1 does.

I called it "SuSE RPMs" because I assume rpmextract 0-2 was actually tested on an RPM or two before it was released. I have tried rpmextract 0-1 and 0-2 on wine-0.9.55-11.1.i586.rpm also, with identical results showing that it is only rpmextract 0-2 which fails (bad return code).

There's an obvious fix here, which is to reinstate rpmextract 0-1 as rpmextract 0-3.

In rpmextract 0-1, the 2 error messages re gzip & cpio are only shown because the first half of "dd if=$pkg ibs=$o skip=1 2>/dev/null | gunzip | cpio -idmuv || dd if=$pkg ibs=$o skip=1 2>/dev/null | bzip2 -d | cpio -idmuv" fails - therefore those 2 error messages can safely be ignored.

Ideally, there would be a command which did "gunzip || bzip2 -d, as appropriate", then the line wouldn't need 2 halves ;)

Aha, the problem is with bsdtar (owned by libarchive), rather than rpmextract.

Simply upgrading from libarchive 2.4.11 to libarchive 2.4.12 (not yet in Arch, hint hint) completely fixes this bug :)

2.4.12 in Testing, please confirm it fixes the bug ;)

I confirm that testing/libarchive fixes the bug. This now succeeds:

rpmextract.sh /var/abs/local/bin32-wine-suse/wine-0.9.56-14.1.i586.rpm || echo "failed"
