[gentoo-user] Blacklisting all packages from overlay except a specific group and version

[gentoo-user] Blacklisting all packages from overlay except a specific group and version

[Nikos Chantziaras]

So, I want to install packages from an overlay, but only from a specific 
group. In this case, the dev-qt/ group. The overlay name is "qt".

It doesn't work:

   package.mask: */*::qt
   package.unmask: dev-qt/*-5.6*::qt

With this, 5.6 versions are still masked.

How do I do this?

Not entirely sure what you wish. Maybe package sets?

Not sure what *you* mean :-) How would package sets help me in masking 
all packages from an overlay and then whilelist only specific ones?

Add the overlay with layman but don't add it to repos.conf. Then symlink
the dev-qt directory of the overlay into your local overlay.

It's a kludge but it works ;-)

Well, I brute-forced it. I've use this mask:

   */*::qt

and this unmask:

   <dev-qt/designer-5.7
   <dev-qt/linguist-tools-5.7
   <dev-qt/qdbus-5.7
   <dev-qt/qtconcurrent-5.7
   <dev-qt/qtcore-5.7
   <dev-qt/qtdbus-5.7
   <dev-qt/qtdeclarative-5.7
   <dev-qt/qtgraphicaleffects-5.7
   <dev-qt/qtgui-5.7
   <dev-qt/qtimageformats-5.7
   <dev-qt/qtmultimedia-5.7
   <dev-qt/qtnetwork-5.7
   <dev-qt/qtopengl-5.7
   <dev-qt/qtpaths-5.7
   <dev-qt/qtprintsupport-5.7
   <dev-qt/qtquickcontrols-5.7
   <dev-qt/qtscript-5.7
   <dev-qt/qtsql-5.7
   <dev-qt/qtsvg-5.7
   <dev-qt/qttest-5.7
   <dev-qt/qtwidgets-5.7
   <dev-qt/qtx11extras-5.7
   <dev-qt/qtxml-5.7
   <dev-qt/qtxmlpatterns-5.7

It works, but I would have expected that computers are good with 
wildcards :-/ The above should be equivalent to this:

   <dev-qt/*-5.7*

but portage refuses to recognize it.

Ah, well.

Why don't you mask versions higher than 5.7 instead?

[gentoo-user] Re: Blacklisting all packages from overlay except a specific group and version

[Nikos Chantziaras]

Because that is already covered by:

   */*::qt

in package.mask. This masks everything from the qt overlay, including 
versions of Qt higher or equal to 5.7.

I only masked >=5.7, then the other packages from the qt overlay would 
not be masked. What I need is mask ALL packages in the qt overlay EXCEPT 
dev-qt/*-5.6.*.

The syntax for "5.6*"-like versions has an equals at the start, for example =dev-qt/qtbase-5.6*, so if it's allowed, =dev-qt/*-5.6*::qt would be the correct package.unmask syntax.  Does that work?

Cheers,
Bryan

That works.

Nope:

   "Invalid atom in /etc/portage/package.unmask/qt: =dev-qt/*-5.6*::qt"

(Doesn't work with or without the "::qt".)

It's the leading "*" that's wrong there, because it's not a glob or a
regex; it's more a placeholder metacharacter with it's own rules. Look
at the relevant section in man 5 ebuild. It's not explicit but it does
strongly hint that "*" goes at the end of a string

It didn't look like it to me at all. From the man page:

   Examples:

   # match anything with a version containing 9999, which can be used in
   # package.mask to prevent emerge --autounmask from selecting live
   # ebuilds
   =*/*-*9999*

So if that works, one would assume that "=dev-qt/*-*5.6*" should work 
just as well :-/

This has always been a horribly misleading example, because it
does not follow the PMS rules of wildcard version matching:
=foo/bar-9999* must mach foo/bar-9999p1 but not foo/bar-9999999

Maybe portage finally dumped this bad case, which was already reported
https://bugs.gentoo.org/show_bug.cgi?id=572178

OTOH, it would appear reasonable that portage could accept
=dev-qt/*-5.6*
although there is of course the ambiguity that it is not clear
that the -5.6* is the version specification.
Perhaps one could open a portage bug/feature request about it.

eix-0.31.7 accepts both (=dev-qt/*-5.6* with PMS rules
as well as the non-PMS =dev-qt/*-*5.6* [with string instead
of PMS matching rules]).
