Bug 270884 – sys-apps/paludis failed to work with Funtoo's new modular package.mask

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Tim O'Kelly 2009-05-22 23:27:50 UTC]

1) 29.04.2009 Daniel Robbins have decided to move to new modular package mask for better support overlays.
http://github.com/funtoo/portage/commit/5dc56b9ee75773a3e5d3a5e0c2a63e57e29d0adc
http://xenoterracide.blogspot.com/2009/02/split-packagemask.html

2) sys-apps/paludis didn't adapt to this change and so began to fail.

Reproducible: Always

Steps to Reproduce:
1. Clone the Funtoo Portage repository (brief instructions are here: http://wiki.github.com/funtoo/portage/first-steps)
2. Switch to the funtoo.org branch of that tree (# cd /usr/portage; git checkout funtoo.org)
3. Sync the tree (# paludis -s)
4. Try to install (or pretend) something: (# paludis -ip ccache)
5. Paludis failed
  * When adding profile configuration file '/usr/portage/profiles/package.mask':
  * In file '/usr/portage/profiles/package.mask': Error reading file: 'Error reading from fd 3: Is a directory' (paludis::SafeIFStreamError) (paludis::ConfigFileError)

Actual Results:  
travel portage # paludis -ip ccache
Building target list...
Unhandled exception:
  * In program paludis (--continue-on-failure if-satisfied --with-unused-dependencies --dl-new-slots as-needed --log-level silent) -ip ccache:

  * In file '/usr/portage/profiles/package.mask': Error reading file: 'Error reading from fd 3: Is a directory' (paludis::SafeIFStreamError) (paludis::ConfigFileError)

Expected Results:  
Normal work as expected.

No packages were specified on the command line, so detailed information is not
available (Paludis can display detailed information for both installed and
installable packages).

So if you're reporting a bug in cat/pkg, use 'paludis --info cat/pkg' instead.

I'm Marking this as RESO INVALID for the following reasons:

1) If anything this is a funtoo problem and as such should not be reported to gentoo's bugzilla.

2) Funtoo uses EAPI 0 ebuilds in the tree. As such, they /should/ have their tree in compliance with PMS(http://dev.gentoo.org/~gentoofan23/pms/head/html/pms.html#x1-450005.2 specifically). Rather, they rely on certain portage behaviour that allows package.mask to be a directory. Whether or not one thinks this should be changed is beyond the scope of this bug report. Paludis follows what the PMS states(and the Gentoo Council approved PMS as a draft standard(any discrepancies have a review process)), and, if anything, portage is the package to be 'fixed' to not allow package.mask be a directory.

I would strongly suggest that the Funtoo people instruct their users that paludis will not work with the funtoo tree due to differences in the profiles/ directory structure.

Change Resolution...

[Comment 3 Tim O'Kelly 2009-05-26 20:05:32 UTC]

Thanks for the detailed explanation. I agree, that it's not a paludis bug.
I like paludis for it's strict following standarts.

But I'm a novice developer and I can't ask Daniel Robbins to change his opinion about modular package.mask. And also I agree with him, that it's not a bad idea and can possibly be included in future versions of PMS (I just don't see, why modular package.mask is bad).

To deal with this situation as I can, I wrote simple workaround for paludis (a hook script), that makes it work with funtoo portage tree by switching it to modular before syncing, and back to singular after it.
I hope it will be useful and so publish it here.

Created attachment 192538 [details]
Should reside in /usr/share/paludis/hooks/auto/

[Comment 5 Marc-Antoine Perennou 2009-09-05 12:02:49 UTC]

I think the simplest thing to do is to rename the modular package.mask as package.mask.d before doing anything with paludis, and rename it as package.mask before syncing or doing anything with portage, that's how I do and it works pretty well
