Funnies ain't so funny.

[IanTrudel]

The sample code Funnies in both Shoes3 and HacketyHack is not working. The download stalling on (possibly) redirections. It loads query on google but certainly not XKCD. Directly invoking HTTPS URL of XKCD will not help. Even famously standard w3c will not work.

Redirect checker reports:

http://xkcd.com/rss.xml
301 Moved Permanently
https://xkcd.com/rss.xml
200 OK

[ccoupe]

According to XKCD.com About page you're supposed to use json. I subscribe to the atom feed and it's OK but perhaps he dropped rss.xml . Same question about w3c does it have and rss.xml? No visual indication that it does.

I would not be surprised it there are https problems in Shoes. I suspect packaging has one.

[ccoupe]

wget https://xkcd.com/rss.xml does produce something reasonable. I get an hpricot error so thats a bug to fix in expert-funnies.rb

[IanTrudel]

Hpricot? Both are using Nogokiri. I also tested download on its own, hence the mention about other non-rss URLs.

[ccoupe]

I didn't have hpricot or nokogiri installed in that ruby (Loose Shoes). Download is actually done in Ruby, a change I made long long ago. lib/shoes/download.rb if you want see what is doing. I also remember a recent commit to Shoes 4 and I made a note to see if Shoes 3.x needs it.

[ccoupe]

An Shoes app that knew how to get the daily comics for various sites (lots of web server issues there) would be good project for someone.

[dredknight]

I can try this one.

[IanTrudel]

Good luck @dredknight !

[ccoupe]

@dredknight - did you volunteer to fix the bug or write a more general comics reader?

[ccoupe]

Fixed the http->https redirect see commit . Works for me and samples/expert-funnies.rb. If you don't want to wait for 3.3.3 beta (I wouldn't), you can fix your Shoes by replacing one file from the github repo lib/shoes/download.rb and add one file: lib/shoes/open-uri-patch.rb

[ccoupe]

The Shoes4 code appears to handle the problem and might be worth backporting into Shoes 3.3.3

[dredknight]

@ccoupe currently writing the shoes-exe GUI. I will take this one after that. Currently I am not sure of approach because adding and using external libs is not my strongest shoes skill but I believe it will be good thing to learn. I will update you when I have some progress. Thanks for the proposals!

[IanTrudel]

For reference only:

Shoes 4 approach does work in Shoes 3 with some changes. It would need download.rb with some minor modifications and http_request.rb with an additional require "net/https" and change @started_proc&.call(response) to @started_proc.call(response) unless @started_proc.nil?.

Your approach @ccoupe is much lighter. Some changes inspired by Shoes 4 might be in order but it's yet unclear whether open_uri with redirection or http_request is better.

@dredknight don't be shy to share with us, we sure can give you feedback. Your contribution is more than welcomed! :)

[ccoupe]

I suspect the Shoe4 code is better but the easy way works, so far.

[IanTrudel]

I suspect the Shoe4 code is better but the easy way works, so far.

Shoes 4 is clean and considerably easier to understand. Sometimes a little over-engineered and the final rendering isn't as good as Shoes 3. For example, the Shoes 4 manual is not rendered properly and looks rather retro.

We sure can stick with open_uri with redirection for now. My previous comment is meant to be a reference in case something comes up, then it will be possible to dig into issue tracker for alternative solution.

[IanTrudel]

The code committed on the repository is not working here. It takes a while and then two windows open up.

[ccoupe]

Did you run that with the old Hacketyhack shoes installed?

Sorry? I made a portable installation of HacketyHack. Shoes 3.3.2 is by default.

> cshoes -v
Shoes walkabout 3.3.2 r2741 i386-mingw32 2.2.4
``

[ccoupe]

I just package up a beta exe walkabout.mvmanila.com/public/shoes/ for 3.3.3 and it does not have the strangeness you show. However it doesn't fix expert-funnies.rb.

[ccoupe]

There's more going on here than I first thought. It's easy to change the xkcd feed to use the proper https: url , and without the open-uri-patch it still hangs on Windows. Digging deeper it seems that nothing that uses a https works. Also in image.rb we don't have the patch but it's hanging getting the rss.xml, not the image.

Updated to include: nothing that uses a https works.

[ccoupe]

Now we have something to dig into. From the shoes.log on windows (cross compiled)

Error in <unknown> line 0 | 2017-02-01 00:13:12 -0700

Certs!

[IanTrudel]

It's possible to disable certificate verification.

output = open(request_uri, {ssl_verify_mode: OpenSSL::SSL::VERIFY_NONE})

[ccoupe]

That does appear to help with some things. Be aware that image caching can fool us!

[ccoupe]

Ok. I think I have something that works for Linux and Windows. Two test scripts, samples/expert-funnies.rb (xkcd with https redirect) and this test

Shoes.app {
  stack do
    image "https://shoes.mvmanila.com/public/images/2017-01-30.gif"
    download "https://xkcd.com/rss.xml" do |dl|
     puts "got xkcd rss.xml"
    end
    download "https://shoes.mvmanila.com/public/images/dino.jpg", save: "dino.jpg" do |f|
      puts "got dino image"
    end
  end
  #image "https://s3.amazonaws.com/static.garfield.com/comics/garfield/2017/2017-01-30.gif"
}

I think this beta will work for windows. It's 22MB because it has debugging symbols - might be helpful in a crash. It has some puts status messages from inside download.rb. Don't forget to clear the image cache with cobbler when testing the image method.

The beta does not verify the ssl certificates but thats OK for now. I suspect a deeper bug between ruby, a possibility out-dated openssl version, and the two Windows ssl dlls included with Shoes.

[dredknight]

Heya. I am back now. Anything I can help with here?

[IanTrudel]

Welcome back @dredknight !

You have plenty of choices. Let's see...

• Adding code samples to Shoes Manual #317
• Documenting Chipmunk basic usage #321
• Documenting mask method #113
• Documenting dash style #244
• Documenting attach => Shoes::Mouse #114
• Adding more relevant samples to samples directory
• Backporting Shoes 4 RSpec #79

[dredknight]

Good :)

[ccoupe]

Closing. Does not fix that download can be very slow. - different issue.
