Bug 30206 – emerge crashes while trying to get deps for binary packages

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Scott Beck 2003-10-02 14:47:30 UTC]

When I try to emerge a large number of binary packages emerge choaks on getting
dependecies for one of the packages. I did some debugging and found the problem.
In portage.py around line 2344 there is:
    if myusevar in myuse:
            enabled=1
    else:
            enabled=0

In the case with binary package myuse comes from somewhere else and it is not
an array so python throws an error.

I'll attach a patch that fixes this but I am not sure if it is the _right_ way
to fix it as I am not a python person.

Reproducible: Always
Steps to Reproduce:
1. setup a system that uses a lot of binary packages
2. emerge -eK world

Actual Results:  
emerge crashed

Expected Results:  
not crashed

Created attachment 18629 [details, diff]
fixes binary package deps checking for me..

[Comment 2 Scott Beck 2003-10-07 04:06:23 UTC]

This patch does not fix things. It only fixes them for certain situations,
for
some reason sometimes what I do a split on is a string and sometimges it
is a
list. I'll try to track it down further.

[Comment 3 Scott Beck 2003-10-07 09:31:22 UTC]

ok, tracked it down I think.
In portage.py there is a function:
def get_use(self,pkgname):
        mysplit=string.split(pkgname,"/")
        if self.isremote(pkgname):
                return string.split(self.remotepkgs[mysplit[1]+".tbz2"]["USE"][:])
        tbz2=xpak.tbz2(self.getname(pkgname))
        return tbz2.getfile("USE")

getfile returns a string. So only in that case does it fail. Changing it
to:
return tbz2.getfile("USE").split()
seems to fix it in all situations.

This is out stable already.
