Bugzilla Bug 107107

I have some old .7z files that p7zip-4.20 opens without any issue.
p7zip-4.27 gives errors as format not recognized/supported.

Reproducible: Always
Steps to Reproduce:
1.try to extract (7z e filename) your old .7z archives with 4.27....
2.
3.

Have you fixed it with trivial command before usage ?

printf '#!/bin/sh\nexec /usr/lib/p7zip/7z "$@"\n' > /usr/bin/7z

P.S. Who's idea was to put copy of /usr/lib/p7zip/7z in /usr/bin ? 7z executable
will attempt to find plugins in /usr/bin/Formats and /usr/bin/Codecs (if you'll
call it with full path) or in ./Formats and ./Codecs (if you'll call it without
fill path and executable will be found via PATH). Wrapper-script is in default
installation scheme BY REASON, not since someone does not know about symlinks!

Fix for 7za is more or less the same:

printf '#!/bin/sh\nexec /usr/lib/p7zip/7za "$@"\n' > /usr/bin/7za

But it's not really needed: 7za is stand-alone archiver, the only thing it can
use is SFX module and ebuild does not install that module, so...

P.S. Mentioned for completeness: I do not think it's good idea to use SFX
archives in first place but p7zip 4.27 DOES support them if you are willing -
just not if you've used Gentoo ebuild...

Yes, that fixed

fix commited into portage without version bump.
added sfx module, changed /usr/bin files to wrappers.
thank you guys for Your support.

Ne marche pas:

Do not EVER use $@ without quotes!

to Canal Vorfeed:

i have a similar problem to yours, that is i get the "No more files" warnings,
too, but i didn't understand how to fix it. i'm sure i didn't have this kind of
problems before updating to the last version...

please do: emerge sync && emerge p7zip
it will solve your problem.
