Sinatra: Upgrading with Sinatra-1.4.7 is taking forever and a lot of CPU right now.

Is this normal to take so long on an old quad Intel system with its SSD? :/

Thank you in advance. :)

That's entirely between you and RubyGems

[zzak]

Yes, this would have nothing to do with Sinatra -- but maybe something you could report to RubyGems or RDoc?

[ctrlcctrlv]

Same story here...

Other gems install fine, so I don't understand how you can blame it entirely on RubyGems or RDoc. Perhaps some feature of RDoc is because used that takes forever to install, I don't know. This isn't a good way to get new users though.

I tested this problem with versions 1.4.7, 1.4.6, 1.4.5, and 1.4.4 on following configurations:

Ruby versions: 2.2.0p0 and 2.1.6p336
Rubygems versions: 2.4.5 and 2.2.3 respectively

And I can see it takes atleast 300 seconds. I'm checking with other versions too and report back.

[lgustafson]

Yes, it hangs for a long time specifically on "Installing ri documentation for sinatra-1.4.7" on ruby 2.3.0 and rubygems 2.5.1 on linux.

[canton7]

Yes, ri and rdoc can take a long time. It's not something that changing any code in this repository will fix. Try passing --no-ri and --no-rdoc

[lgustafson]

Agreed, ultimately the problem is not Sinatra's, however, it may be possible to determine if there is something in particular in one of the translations, for instance, that is causing it to take so long.

[RailsDuck]

The same thing is happening here, but I know how to solve it. First of all, you either tried these codes:
gem install padrino
sudo gem install padrino

Now, for whatever you tried, type this code in instead and it will fix all of your problems:
gem install padrino --no-ri --no-rdoc
sudo gem install padrino --no-ri --no-rdoc

This will make your normal, 15 minute cycle, drop to 30 seconds. I feel like I have wasted a ton of time, and I hope this doesn't happen to you too!

UPDATE:
I used the Padrino gem instead of the Sinatra gem, so be sure to not use Padrino if you are working in Sinatra!

[antdude]

RailsDuck: Interesting. Well, with ri (what is it?) and rdoc (documents I assume?) should be fixed.

[RailsDuck]

As long as it worked, you should be good. 👍 or 👎 ?

[zzak]

This is an RDoc issue, so I'm locking this ticket.
