[gentoo-user] problems emerging some ruby packages

[gentoo-user] problems emerging some ruby packages

[Jack]

I'm helping support a web site hosted at Heroku and written in Ruby on  
Rails.  Following some tool upgrades there, I upgraded my local rails  
to 3.1, uninstalling the previous version 2.7.  I  now have  
RUBY_TARGETS="ruby31" in make.conf. and several specific dev-ruby  
package versions in package.accept_keywords.  Most of them upgraded  
fine, or at least reinstalled (using a version supporting ruby31 after  
unmerging the old version) but some are giving me grief.

For example, "emerge -1 dev-ruby/thor" gives me

!!! Problem resolving dependencies for dev-ruby/thor
... done!

!!! The ebuild selected to satisfy "dev-ruby/thor" has unmet  
requirements.
- dev-ruby/thor-1.2.1::gentoo USE="-doc -test" ABI_X86="(64)"  
RUBY_TARGETS="-ruby27 (-ruby30) (-ruby31)"

   The following REQUIRED_USE flag constraints are unsatisfied:
     any-of ( ruby_targets_ruby27 ruby_targets_ruby30  
ruby_targets_ruby31 )

I would expect USE_RUBY="ruby31" to translate into ruby_targets_ruby31,  
but even explicitly adding that to package.use has no effect.  Is there  
something I'm missing turning off ruby31, specifically for just a small  
number of packages?  (so far the only other one with this problem is  
dev-ruby/mini_mime).

Portage has two versions of thor: 1.1.0 and 1.1.2, both marked stable  
for amd64, and 1.2.1 has USE_RUBY="ruby26 ruby27 ruby30 ruby31" so I  
don't see any reason it's not working.

I already have railties installed (using -O) with ruby31, and it  
depends on thor via ruby_add_redepend, which I read as requiring thor  
with ruby31.  thor is not mentioned in any file under /etc/portage.

Does anybody see what I'm missing?

Maybe you have something in package.use for this package?

You could try to get emerge to tell you more explicitly what problem it has

USE="ruby_targets_ruby31" emerge -av dev-ruby/thor

Thanks for the response.

"grep -ir thor ." in /etc/portage has no hits.  In addition "grep -ir  
ruby ." in /etc/portage shows only package.accept_keyword entries and  
RUBY_TARGETS="ruby31" in make.conf.

I don't see how this is any different from putting it in package.use,  
but it has the same lack of effect.

Can anyone explain (or point me the the fine manual page I missed) the  
exact meaning of (-ruby31) in

!!! The ebuild selected to satisfy "dev-ruby/thor" has unmet  
requirements.
- dev-ruby/thor-1.2.1::gentoo USE="-doc -test" ABI_X86="(64)"  
RUBY_TARGETS="-ruby27 (-ruby30) (-ruby31)"

and why is ruby27 not in parens, but the other two are?  Is that just  
the assumption that ruby31 is off in any ebuild which does not  
explicitly mention it, or does it reflect an explicit turning off of  
that flag?

ruby30 and ruby31 are in parentheses, which means they are not available.

The ebuild contains USE_RUBY="ruby26 ruby27" ruby_add_bdepend "

Have you tried setting RUBY_TARGETS to ruby27 for this package?

I must say I find the whole RUBY_* thing even more troublesome than the
PYTHON_* stuff, and that's saying something!

As per the emerge man page:

-        prefix      not enabled (either disabled or removed)
[snip...]

()       circumfix   forced, masked, or removed

On a stable system with default ruby targets, I get this:

[ebuild  N     ] dev-ruby/thor-1.2.1:1::gentoo  USE="-doc -test" 
RUBY_TARGETS="ruby27 (-ruby30) (-ruby31)" 95 KiB

and, dev-lang/ruby-2.7.6:2.7 is drawn in as a build dependency:

[ebuild  N     ] dev-lang/ruby-2.7.6:2.7::gentoo  USE="gdbm ipv6 rdoc ssl -
berkdb -debug -doc -examples -jemalloc -jit -rubytests -socks5 -static-libs -
systemtap -tk -xemacs" 11,802 KiB

NOTE: ruby 3.0 and 3.1 are marked as testing.

I explicitly have ruby-3.1 unmasked with "=dev-lang/ruby-3.1.2-r1  
~amd64" in package.accept_keyword, and USE_RUBY="ruby31" in make.conf.   
I do not see any reference to ruby in the profile.  Is there somewhere  
else I need to unmask something?  emerge --info also says  
'RUBY_TARGETS="ruby31"' as its only reference to a specific ruby  
version.

As I said in my reply to Neil, why would this happen in just a handful  
of packages, but not in over thirty others?  mini_mime is the other  
problem package, and it does not use ruby_add_bdepend so there is only  
one line with USE_RUBY:  'USE_RUBY="ruby26 ruby27 ruby30 ruby31"'.

So - why is ruby31 disabled for (so far) only these two packages?    
(The other packages which are failing depend on one of these two.)

Maybe these two are just written more strict? I'm unable to read the
eclass to determine how it masks these flags on a stable system on
these packages, it will happily install it with ruby31 on my unstable
system, but you can try to unmask the flag in
/etc/portage/package.use.mask

dev-ruby/thor -ruby_targets_ruby31

Not the minus sign.

Well, this almost did the trick.  That file has to be in  
/etc/portage/profile.  Just having it in /etc/portage did not work.  It  
turns out the masking of ruby_targets_ruby30 and ruby_targets_ruby31 is  
in /usr/portage/profiles/base/use.stable.mask.   I still have no idea  
why ruby31 was masked for these two packages (thor and mini_mime) but  
not for over thirty other dev-ruby packages I have installed.

My next issue is that I installed several packages with -O (skip  
dependencies) so now I have to work my way through finding all the  
uninstalled dependencies I skipped, many of which will need to be  
unmasked as they are testing.

Thanks for all the suggestions and support, and I'll report back either  
when it's all done or if I find another blockage.

Try setting in your /etc/make.conf this expression instead:

RUBY_TARGETS="ruby31"

as per https://wiki.gentoo.org/wiki/Ruby

and if you have not yet switched to using it, run:

eselect ruby set ruby31

That's what you'd add in your make.conf, for this ruby slot to be used 
globally.

I think it is relevant to how these USE variables are parsed and their syntax.  
If you specify the ruby version via a USE flag, then this should be:

USE="ruby31" emerge -pv blah-blah
 

You need to specify it as above and since you want to use ruby31 wholesale on 
your system, set it in make.conf as the wiki page explains.

Given everything below - what other reasons might there be for this?   
I've yet to find any pattern of the difference between the ebuilds for  
the small number of dev-ruby packages that show this problem, and those  
for the the thirty plus which have installed just fine.

Hmm.  It looks to me that line should probably be 'USE_RUBY="ruby26  
ruby27 ruby30 ruby31" ruby_add_bdepend "'  However, as it only affects  
the required ruby version for two depedencies only if the test use flag  
is set (it is not) I'm not sure why it would matter.

I suppose it is likely just a typo in the ebuild.  They removed ruby25  
from 1.1.0 but didn't add the newer ruby versions.  Actually even 1.1.0  
may be broken as it includes ruby30 in USE_RUBY but not on the  
ruby_add_bdepend line.  However, I just made an -r1 in my local  
overlay, adding the new ruby versions to that line, and I still get the  
same error.  So I'm actually still stuck figuring out why this ebuild  
won't take ruby31.

Why would I do that if I don't have ruby-2.7 installed, nor do I want  
to?

That I agree with.  If I knew then what I know now, I would have argued  
much more vigorously against using Ruby on Rails for this web site.   
But that's fodder another entire thread.

We don't always get what we want. If thor currently needs 2.7 then you
have to have it if you want thor.

Try it with an emerge -p. Whether it works or not, you will have further
clues as to the source of the issue.
