file collisions: /usr/bin/python-exec2

[strogdon]

Both sage-baselayout and dev-vcs/git install the symlink

ls -al /usr/bin/python-exec2
lrwxrwxrwx 1 root root 31 Feb 19 20:51 /usr/bin/python-exec2 -> ../lib/python-exec/python-exec2

and I get file collisions that don't seem to be resolvable. I don't recall seeing this previously? And I have collision-protect turned off in make.conf. Perhaps the order of install is important. This appeared while rebuilding git-2.0.5 with sage-baselayout-9999 installed.

[strogdon]

I should have posted the failure:

Detected file collision(s):

        /usr/bin/python-exec2

Searching all installed packages for file collisions...

Press Ctrl-C to Stop

sci-mathematics/sage-baselayout-9999:0::sage-on-gentoo

Package 'dev-vcs/git-2.0.5' NOT merged due to file collisions. If
necessary, refer to your elog messages for the whole content of the
above message.

ll /usr/bin/python-exec2
ls: cannot access /usr/bin/python-exec2: No such file or directory

Not present here. I will have to see if it is something from an eclass update.

[kiwifb]

eclass flip-flopping, are you a late upgrader for dev-lang/python-exec? It should be 2.0.1-r1.

[strogdon]

That's the python-exec that I have. FWIW this appeared after a sync and updating world.

[kiwifb]

OK doing that just now, we'll see.

[kiwifb]

Just reinstalled git, still no /usr/bin/python-exec2

[strogdon]

Ahh. python-exec is old! It was never updated. Let me manually do it and then see.

[strogdon]

The python-exec is old

ls -al /usr/bin/python-exec
-rwxr-xr-x 1 root root 1397 Mar 12  2014 /usr/bin/python-exec

I manually updated python-exec and I still get the collisions when installing git. So I

rm /usr/bin/python-exec
emerge -1 dev-lang/python-exec 
emerge -1 sci-mathematics/sage-baselayout
emerge -1 dev-vcs/git

And now

* Detected file collision(s):
 * 
 *      /usr/bin/python-exec2
 * 
 * Searching all installed packages for file collisions...
 * 
 * Press Ctrl-C to Stop

with

ls -al /usr/bin/python-exec2 
lrwxrwxrwx 1 root root 31 Feb 22 14:41 /usr/bin/python-exec2 -> ../lib/python-exec/python-exec2

Strange?

[kiwifb]

I have a dim memory that the file needed to be removed manually.

rm /usr/bin/python-exec2

[strogdon]

Here after removing the symlink /usr/bin/python-exec2, sage-baselayout-9999 re-installs it. And then installing git will fail.

[kiwifb]

With what message?

[strogdon]

I think it failed because of file collisions, although I'm not now positive. I did

rm /usr/bin/python-exec2
emerge -1 dev-vcs/git
emerge -1 sci-mathematics/sage-baselayout

without a problem. And

rm /usr/bin/python-exec2
emerge -C git
emerge -1 sage-baselayout

pulled in git first and then sage-baselayout. So there must be a correct order of merging. I guess.

[kiwifb]

Still very curious. I wonder if we should ask someone like mgorny. Then again I am surprised you have not been forced to upgrade earlier so it may be a pitfall due to slow removal of the link.
