Bugzilla Bug 229897

Rubygems ebuilds use find without path and they also use xargs instead of
-exec.

The incorrect use of find makes it fail i.e. on GentooFreeBSD but still this
bug is not only related to BSD or ALT its a general problem that simply does
not show up on linux.



See this manual at the end:
http://devmanual.gentoo.org/tools-reference/find/index.html

All the ebuilds should be patched like that:
-       find -name '.*' -type f -print0|xargs -0 rm
+       find "${S}" -name '.*' -type f -exec rm '{}' \;

Reproducible: Always

Steps to Reproduce:
1. emerge rubygems on gfbsd or on s system with no GNU-find

Actual Results:  
> ...
>  * Applying rubygems-1.2.0-setup.patch ...                                                    > [ ok ]
> find: illegal option -- n
> find: illegal option -- a
> find: illegal option -- m
> find: illegal option -- e
> find: .*: No such file or directory
> >>> Source unpacked.
> ...

These messages appear somewhere in the log but the merge does not fail.

Expected Results:  
Find should locate the files and they should be removed.



I checked for 1.2.0 the qlist output for the patched version and the original
was the same. So there where no files found/deleted in version 1.2.0, maybe the
statement is superfluous anyway.

I grepped through the tree for "find -" and this mistake seems pretty common.
There are some hits on packages that are linux-only like
sys-kernel/linux-headers or media-gfx/bootsplash-themes.

But there are also a lot of hits on packages that might be of interest for
other OSs where find without path may not work. i.e:
dev-util/netbeans
dev/libs/openssl
dev-java/jexcelapi

These are only examples, actually there are quite some packages having that
bug. For a complete list i suggest you to grep for yourself.

This is kind of a meta-bug and i dont know how to handle that so i reported it
along with this one.

"-name '.*'" should be superfluous.

No. That would match "*" instead of ".*". But as i said the whole thing seems
to be superfluous, at least for 1.2.0.

I wonder which version of rubygems shipped with these dot-files, since I could
not find any... I've removed the find from all stable and new versions, the
other versions will be removed shortly anyway.

Thanks for reporting!
