[gentoo-portage-dev] Error logs

Hi,

In reference to this forum post -
https://forums.gentoo.org/viewtopic-t-1091144-highlight-.html , I was told
that several users found wrong information in the portage error logs
pointing them to the wrong directory for distfiles to be downloaded and
placed in for the emerge to work when the tree variable was displayed to
the user, for the user to place the downloaded files in.
Instead of not using the tree variable to point to the distfiles location
(and having a less descriptive error message), was using some other form of
keeping a track of where the files are stored discussed? Or figuring out
why the variable pointed to the wrong directory?

I could take a look at it if that is a feature you would be open to having.

Regards,

Can you highlight some more examples (good & bad) as even the forum post
doesn't really go into much detail about what's present and missing? I can
see that dev-libs/cudnn is poor - usually LICENSE-restricted files give
some sensible directions, iirc. Not sure quite why this package is an
exception if it's problematic in being mirrored ...

For oracle-jdk - https://pastebin.com/iT1XsfUv
In this case the log tells you to download jdk-8u192-linux-x64.tar.gz from
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
and place it in your distfiles directory. But it does not tell you where
your distfiles directory is. (This is more descriptive than cudnn and one
could run a recursive bash script to find the distfiles directory but
instead of saying distfiles directory, if it printed out the actual
directory location it would be far more convenient)

Regards,

I'm sorry to say that it's intentionally vague. Since ebuilds run in a
environment standardized environment [1], the true location of your
distfiles directory is not strictly knowable within ebuild scope.

To make things more interesting, there are plans to roll out a split
distfiles directory structure [2].
