unable to unmask package use flag

Hi there

Im getting the following masked package unable to be unmasked.

my ruby target is 2.7 because of GitLab, but I have an app that does not yet have have Ruby27 support so Im going though the needed dependencies and unmasking ruby26. I don't want to unmask ruby26 system wide for one app. Also the idea is to set the explicit exceptions to the base I've set.

things have been going well until this one package, no matter what I do in /etc/portage/profile/package.use.mask it won't mask the ruby27 flag I've set in make.conf, no wildcards seem to work

ideas?

Code: Select all

emerge: there are no ebuilds to satisfy "dev-ruby/public_suffix:3[ruby_targets_ruby27(-)]".
(dependency required by "dev-ruby/addressable-2.7.0::gentoo[ruby_targets_ruby27,-test]" [ebuild])

as per the 3.1.1 ebuild:

Code: Select all

USE_RUBY="ruby24 ruby25 ruby26"

it does not support ruby27

https://gitweb.gentoo.org/repo/gentoo.g ... 1.1.ebuild

Code: Select all

emerge: there are no ebuilds to satisfy "dev-ruby/public_suffix:3[ruby_targets_ruby27(-)]".
(dependency required by "dev-ruby/addressable-2.7.0::gentoo[ruby_targets_ruby27,-test]" [ebuild])

If you look in addressable ebuild you see

Code: Select all

ruby_add_rdepend "|| ( dev-ruby/public_suffix:4 dev-ruby/public_suffix:3

So you should install dev-ruby/public_suffix:4 with ruby27 target and emerge resolve problem

Hi there

im a bit disappointed that no one read my package.use.mask supplied in my post, per the docs, to unmask a parent mask.

Im not trying to use Ruby27 im tying MASK ruby27. to use ruby26 for my application. I KNOW ruby27 is not supported. I'm forcing ruby27 system wide and then removing the mask on a per-application basis by explicitly setting the flags on the required packages.

make.conf: RUBY_TARGETS="ruby27" <- this remains. exceptions made in package.use.mask and package.use I am keeping one version of ruby on my system as the general version.

as my post indicated but no one noticed:

emerge: there are no ebuilds to satisfy "dev-ruby/public_suffix:3[ruby_targets_ruby27(-)]". (the ability to mask Ruby27 for ruby26 is masked by my make.conf - the minus in brackes (-) ) I cannot, no matter what I put in package.use.mask, unmask ruby26 for this package.

Im tying to REMOVE the forced ruby27 flag I have set in make.conf because the APP, as others have pointed out, does not support ruby26, and if you looked at my package.use.mask, you see im NEGATING the ruby_targets_ruby27 flag, to then, in package.use enable ruby26

localhost ~ # cat /etc/portage/profile/package.use.mask
dev-ruby/ruby-openid -ruby_targets_ruby27
dev-ruby/rack -ruby_targets_ruby27
dev-ruby/htmlentities -ruby_targets_ruby27
=dev-ruby/crass-1.0* -ruby_targets_ruby27
>=dev-ruby/rack-test-0.6.3:* -ruby_targets_ruby27
>=dev-ruby/rexical-1.0.7 -ruby_targets_ruby27
>=dev-ruby/mini_mime-0.1.1 -ruby_targets_ruby27
*dev-ruby/public_suffix* -ruby_targets_ruby27 <----- disable ruby27, to allow ruby26 flag.

/etc/portage/package.use/ruby
>=dev-ruby/fcgi-0.9.2.1-r1 ruby_targets_ruby26 <--- force ruby26 (random example, there are close to 40 lines in this file all enabling ruby26)
>=dev-ruby/mini_magick-4.11.0 ruby_targets_ruby26
>=dev-ruby/ruby-net-ldap-0.17.0 ruby_targets_ruby26
>=dev-ruby/redcarpet-3.5.1 ruby_targets_ruby26
>=dev-ruby/mysql2-0.5.3-r1 ruby_targets_ruby26
>=www-apache/passenger-6.0.6 ruby_targets_ruby26

so why is this in package.use.mask not working: *dev-ruby/public_suffix* -ruby_targets_ruby27 DESPITE the examples in the SAME file working.
emerge: there are no ebuilds to satisfy "dev-ruby/public_suffix:3[ruby_targets_ruby27(-)]"

RUBY_TARGETS="ruby26 ruby27" in make.conf is not an option I will consider. package.use.mask and package.use to unmask ruby26 is the only accepted solution.

The /etc/portage/profile/package.use.mask and /etc/portage/profile/use.mask works differently that /etc/portage/package.use, if you want unmask use minus prefix on use flag otherwise without

Hi there

if you want unmask use minus prefix on use flag otherwise without

you've repeated what I understand already why is my line not being respected?

why is this not working when I have it set in my package.use.mask, the minus prefix is ALREADY there, i've attempted to wildcard the package name to match, but It will not negate my ruby27 flag, what is wrong with this line? there are other examples in the same file that work just fiine, just not this one package.

*dev-ruby/public_suffix* -ruby_targets_ruby27

this is my package.use.mask as is, look at the last line, you clearly see i've already masked ruby27 for other packages and those are fine. I have been able to enable ruby26

localhost ~ # cat /etc/portage/profile/package.use.mask
dev-ruby/ruby-openid -ruby_targets_ruby27
dev-ruby/rack -ruby_targets_ruby27
dev-ruby/htmlentities -ruby_targets_ruby27
=dev-ruby/crass-1.0* -ruby_targets_ruby27
>=dev-ruby/rack-test-0.6.3:* -ruby_targets_ruby27
>=dev-ruby/rexical-1.0.7 -ruby_targets_ruby27
>=dev-ruby/mini_mime-0.1.1 -ruby_targets_ruby27
*dev-ruby/public_suffix* -ruby_targets_ruby27 <----- disable ruby27, to allow ruby26 flag. why is this not working?

Sorry I don't understand. You say

No with minus you unmask the use flag.

look at my file.. I've already negated my ruby27 flag.....the negation exists.

localhost ~ # cat /etc/portage/profile/package.use.mask
dev-ruby/ruby-openid -ruby_targets_ruby27
dev-ruby/rack -ruby_targets_ruby27
dev-ruby/htmlentities -ruby_targets_ruby27

=dev-ruby/crass-1.0* -ruby_targets_ruby27 <- ruby27 masked allowing ruby26 -- look at package.use below showing flagging ruby26

>=dev-ruby/rack-test-0.6.3:* -ruby_targets_ruby27 <- ruby27 masked allowing ruby26
>=dev-ruby/rexical-1.0.7 -ruby_targets_ruby27 <- ruby27 masked allowing ruby26
>=dev-ruby/mini_mime-0.1.1 -ruby_targets_ruby27 <- ruby27 masked allowing ruby26

*dev-ruby/public_suffix* -ruby_targets_ruby27 <--- disable ruby27, to allow ruby26 flag. why is this not working?

then I flag the package for ruby26....

cat /etc/portage/package.use/ruby
....

>=dev-ruby/crass-1.0.6 ruby_targets_ruby26

....

Hi there

so this was not only needing to disable ruby27 but enable ruby26 as it was explictly masked by the ebuild

Code: Select all

(dev-ruby/addressable-2.7.0:0/0::gentoo, ebuild scheduled for merge) USE="-doc -test" RUBY_TARGETS="-ruby25 (-ruby26) ruby27" pulled in by

fixed by the following, there was also a conflict with dev-ruby/addressable-2.6.0 as 2.7.0 had a ruby27 flag and 2.6.0 did not, so I masked 2.7.0 and explictly enabled ruby26 to be sure. Public suffix needed ~amd64 keyword to get its correct version with the correct flag enabled.

Code: Select all

<dev-ruby/addressable-2.7.0 -ruby_targets_ruby27 ruby_targets_ruby26
=dev-ruby/public_suffix-4.0.5 -ruby_targets_ruby27 ruby_targets_ruby26

If I understand your posts correctly, then your understanding is backward. In package.use.mask:

category/package flag: force category/package to MASK OUT flag, thereby preventing it from being enabled, regardless of the user's USE / RUBY_TARGETS values.
category/package -flag: force category/package to UNMASK flag, thereby allowing, but not requiring the user to enable the flag.

Your shown file allows, but does not require, you to enable ruby27 on the listed packages. It has no effect on other flags, such as ruby26. It has no effect on packages that would already not USE=ruby_targets_ruby27.

pakage.use.mask is a positive effecting mask on the build process, so yes you want to MASK *something* then you are correct in your understanding. Also respecting the inheritance of profile -> make.conf -> package.* -> ebuild

my end goal is negating a flag already negated, (-ruby_targets_ruby26), the default of the system: make.conf - RUBY_TARGETS="ruby27" : ruby27 flag is enabled, note the missing ruby26 target. Explicitly compiling against ruby27 only.

my goal, to SELECTIVELY enable RUBY_TARGETS="ruby26" on a PER PACKAGE BASIS - not globally in make.conf... so far still positive effect on the use flag ruby_targets_ruby26

since the majority of the packages I was emerging were MASKED because of make.conf NOT adding RUBY_TARGETS="ruby26", thus NOT enabled - negated by make.conf.

so now since my RUBY_TARGETS="ruby27" (root) - make.conf (negated ruby26)
I need to ENABLE RUBY_TARGETS="ruby26" (child) - package.use.mask

so...how does one negate a negative....in math, one does this (negative * negative) = positive (-2*-2) == 4. negating the negative. As I clearly stated in the beginning, so since my flag because make.conf = RUBY_TARGETS="ruby27" (-ruby_targets_ruby26). I need to negate that.

So, the end result was TWO positives, both ruby27 (system set in make.conf) and ruby26 (for my application in package.use.mask) being enabled, where, because of make.conf, it was NOTenabled.

make.conf effect:

Code: Select all

[ebuild  N    ~] dev-ruby/addressable-2.7.0  USE="-doc -test" RUBY_TARGETS="-ruby25 -ruby26 ruby27"

then lets look at the package, it has an explicit mask of ruby26 in the ebuild, the root cause of this thread, also explaining why I needed to explictly enable ruby26 (ruby_targets_ruby26) on the package as well as negating ruby27 (-ruby_targets_ruby27)

Code: Select all

(dev-ruby/addressable-2.7.0:0/0::gentoo, ebuild scheduled for merge) USE="-doc -test" RUBY_TARGETS="-ruby25 (-ruby26) ruby27" pulled in by

so my understanding of having to mask a negative was correct, as the math proves. This started out as a negative, see, ruby26 was masked because of make.conf, and explicitly by the ebuild itself, then unmasked, (positive effect of negative masking) in package.use.mask, respecting config inheritance.

Code: Select all

[ebuild  N    ~] dev-ruby/addressable-2.7.0  USE="-doc -test" RUBY_TARGETS="-ruby25 ruby26 ruby27"
