[gentoo-user] eix-test-obsolete problem

[Shaochun Wang]

I have an local overlay, which contains some ebuild written by myself or
copied from bugzilla.

When I execute eix-test-obsolete, it display the following wierd thing:

	Installed packages with a version not in the database (or masked):
	
	[I] app-misc/beagle (0.3.3[?]@02/27/08): Search tool that ransacks 
	your personal information space to find whatever you're looking for
	[I] net-ftp/proftpd (1.3.1[?]@02/20/08): An advanced and very 
	configurable FTP server.
	[I] x11-misc/qterm (0.4.1[?]@03/07/08): QTerm is a BBS client in Linux.
	[1] /usr/local/portage
	
And I also notice that when I execute command update-eix, the following is printed:
	Reading Portage settings ..
	Building database (/var/cache/eix) ..
	[0] "gentoo" /usr/portage/ (cache: metadata)
	     Reading 100%
	[1] "" /usr/portage/local/layman/sajinet (cache: none)
	     Reading 100%
	[2] "berkano" /usr/portage/local/layman/berkano (cache: none)
	     Reading 100%
	[3] "" /usr/local/portage (cache: none)
	     Reading 100%
	Applying masks ..
	Database contains 12454 packages in 152 categories.

It seems that there is no cache in the portage overlays, so update-eix
can't get the package information in these overlay.

What can I do to get the local overlay picked by eix?

That's normal. eix still gets the information, by reading the filesystem.
The cache is simply a way of speeding u this process for large trees.

It should already, if you search for a package that has an ebuild in the
overlay, it should display it, along with the name of the overlay.

% eix openchrome
* x11-drivers/xf86-video-openchrome [1]
     Available versions:  0.2.901 {dri}
     Description:         VIA unichrome graphics driver

This is your problem: eix is not able to detect from which repository
this version was installed. The reason is that you have not given your
overlay a name.

Some time ago, eix was able to guess the repository by means of the
information in /var/db/*/*/environment.bz2, but new portage versions
do not store that information in this file anymore.

The clean solution of your problem is to give your overlay a name
(i.e. to create a "profile" subdirectory in your overlay and store
your name in a new file "profile/repo_name") and then to reemerge
all packages from the overlay so that the name is also stored in
the /var/db database. (Instead of reemerging you can also hack
the database manually and create the files /var/db/*/*/repository
with the corresponding overlay name in it; however, I give no
guarantee that this will not have unexpected side effects...).

If you want that eix-test-obsolete just ignores the repository
(i.e. that 0.3.3[?] is "found" in the database even if the version
in the database is from a possibly different overlay), set
   NONEXISTENT_IF_OTHER_OVERLAY='false'
in /etc/eixrc. However, I would not recommend this.

The output of update-eix is as expected:

> 	[3] "" /usr/local/portage (cache: none)
            ^^                            ^^^^
This is empty, because you have not       ^^^^
named your overlay yet                    ^^^^
                                          ^^^^
                    This means that the cache method "none" is used
                    (man eix for details) which is the default for
                    overlays unless you set something special.[*]

[*] With eix-0.12.0 the default has changed to a new cache method
    which appears superior (but has some security risks).
    The previous cache method "none" was renamed.

Thanks very much. It works.

BTW, there is a trivial error in you reply as following

It should be		   profiles/repo_name
