Bugzilla Bug 51552

a variable is set in /etc/profile.env, say 'AMANDA_CONFIG_NAME=xyz'.
now in the emerge enviroment
'export AMANDA_CONFIG_NAME=foobar'
'emerge package'
inside the package, AMANDA_CONFIG_NAME is xyz and not foobar.

Reproducible: Always
Steps to Reproduce:
'emerge amanda'
then see bug 51370, comment #7.


Expected Results:  
local environment should override /etc/profile.env

as a further note, older versions of portage do this correctly, as the
app-admin/amanda package used to rely on it and work perfectly when I
originally wrote it.

Jason: they are not the same!
the changes listed under that bug only provide a special environment for portage.
i want emerge to use the environment present when it is run, which is NOT the same as the contents as profile*, .bashrc, et al, as I've set environment variables locally.

the closest thing is the mention of 'It should go after CC/CXX are saved and restored from sourcing profile.env, because the admin may wish to override CC for a particular package in /etc/portage/bashrc.' I want practially all variables to have the same behavior as CC/CXX.

That's not easy in the least... Although it semi-reasonable...

carpaski: i don't see it as that difficult at all.
at the very start of emerge, it should capture the enviroment in place.
1. printenv > tmpfile (this needs to be done as early as possible)
2. source /etc/profile, /etc/portage/bashrc etc.
3. remove all special items from tmpfile (just use egrep -v)
4. eval `cat tmpfile`
5. you may want to save this environment now so it can be re-used faster instead of re-doing the above.

Robin: Apologies. The bugs are definately related though.

any progress on this?

*bump*

*bump back*
Nick, the daemon fixes this (fyi)...

Just testing again, this seems to work as of 2.0.51.22-r1

Erm, not really fixed.
