In short, I previously ran by backup script that exported A=/media/arch_longtime/arch_2009_01_01_part_only_moon-gen-3_and_home_and_hosts in my console and now this is causing side effect on emerge. => whatever the environment is, emerge should satanise this kind of variables before doing his stuff. This bug may be a dup of an other one i saw long time ago about satanisation. I just don't find it again. Of course, the WA is trivial: export -n A But, it would be nicer, and even "more secure" if emerge had satanise all variables he needs before starting up. Error was obvious, because I used A to store a path; it would have been way less obvious if I used it to store ebuild names ...
Sorry for misspell :'( I knew something was wrong :/
Created attachment 177303 [details, diff] fix $A leakage If this patch is saved as /tmp/env_blacklist.patch, then it can be applied as follows: patch /usr/lib/portage/pym/portage/__init__.py /tmp/env_blacklist.patch
is $A the only leaking one ? I did not test the other ones, but from memory, portage internally uses at least 8 variables ... i don't find the list, but from memory: $S $T $D ... may also be affected the same way IMHO. Zac, do you want me to test the patch ?
I already tested the patch, so you don't have to. Because of various quirks in the portage code most other variables aren't affected the same way that $A was. Anyway, I'll go ahead and add the rest to the blacklist for conistency's sake.
I fell on that one with badluck. Reading various ebuild, I also find, possibly $P $PV $T ... I don't have enough experience to give you a nice list. I just say that if I could trigger $A, other ones *could* be. Good luck.
This is fixed in 2.1.6.5 and 2.2_rc21.
Fixed, verified, closing.

Created attachment 195997 [details, diff] fix regression in blacklist handling This is fixed in svn r13730.
This is fixed in 2.2_rc34.
I don't know about 2.1 branch, but 2.2 is now OK for me. Jumped from 2.2_rc33 to 2.2_rc41 and it's working fine. At least for variable $A :)
