Encoding is not available to Ruby scripts on 1.2

[jferris]

You can reproduce this with the following Ruby script:

require "uri"

I get the following error:

   weechat =!= | ruby: error: eval:31:in `module_eval': uninitialized
               | constant Encoding::UTF_7 (NameError)
   weechat =!= | ruby: error:      from

   weechat =!= | ruby: error:      from eval:31:in `module_eval'
   weechat =!= | ruby: error:      from eval:31:in `load_eval_file'

I'm on Ruby 2.2.2, Weechat 1.2, Arch Linux:

[evilgawd]

Is there any workaround for this ?

[flashcode]

For now I have no workaround.
I'll have to dig this problem, but I'm not an expert with Ruby so any help is appreciated to fix this problem.

[akaritakai]

I also ran into this on 1.3 while using a gem that required uri. I don't have a workaround either.

[ChinnoDog]

I found this problem in 1.3 after doing a package upgrade on my Ubuntu server. I use slacklog.rb and encounter this error when I attempt to load it in weechat. I used irb to interactively load the script's object and it does not complain. The uri issue only appears in weechat. I only have one version of Ruby on my server and that is 2.0.

[flashcode]

Ruby developers/gurus: a patch is still welcome for this issue :)

[akerl]

So the encodings made available inside weechat differ dramatically from those on the system:

irb(main):001:0> Encoding.list.join(',')
=> "ASCII-8BIT,UTF-8,US-ASCII,UTF-16BE,UTF-16LE,UTF-32BE,UTF-32LE,UTF-16,UTF-32,UTF8-MAC,EUC-JP,Windows-31J,Big5,Big5-HKSCS,Big5-UAO,CP949,Emacs-Mule,EUC-KR,EUC-TW,GB2312,GB18030,GBK,ISO-8859-1,ISO-8859-2,ISO-8859-3,ISO-8859-4,ISO-8859-5,ISO-8859-6,ISO-8859-7,ISO-8859-8,ISO-8859-9,ISO-8859-10,ISO-8859-11,ISO-8859-13,ISO-8859-14,ISO-8859-15,ISO-8859-16,KOI8-R,KOI8-U,Shift_JIS,Windows-1251,IBM437,IBM737,IBM775,CP850,IBM852,CP852,IBM855,CP855,IBM857,IBM860,IBM861,IBM862,IBM863,IBM864,IBM865,IBM866,IBM869,Windows-1258,GB1988,macCentEuro,macCroatian,macCyrillic,macGreek,macIceland,macRoman,macRomania,macThai,macTurkish,macUkraine,CP950,CP951,stateless-ISO-2022-JP,eucJP-ms,CP51932,EUC-JIS-2004,GB12345,ISO-2022-JP,ISO-2022-JP-2,CP50220,CP50221,Windows-1252,Windows-1250,Windows-1256,Windows-1253,Windows-1255,Windows-1254,TIS-620,Windows-874,Windows-1257,MacJapanese,UTF-7,UTF8-DoCoMo,SJIS-DoCoMo,UTF8-KDDI,SJIS-KDDI,ISO-2022-JP-KDDI,stateless-ISO-2022-JP-KDDI,UTF8-SoftBank,SJIS-SoftBank"

23:07:04     ruby: loading script "/home/akerl/.weechat/ruby/autoload/dummy.rb"

That script uses the following the generate that output:

Weechat.print '', Encoding.list.join(',')

Was there a code change recently that would have impacted the locales you present when loading Ruby?

[akerl]

Looks very related to https://savannah.nongnu.org/bugs/?41115

[akerl]

My C skills are pretty horrible, but looking at d8b9e0a, it looks like you may be checking defined(RUBY_API_VERSION_MAJOR) before #include <ruby/version.h>, which is the header that defines RUBY_API_VERSION_MAJOR. Based on that, it looks like #include <ruby/encoding.h> would never be utilized

[akerl]

No luck. Removing that had no visible impact

[akerl]

@flashcode Have you had a chance to look into this? It's pretty crippling given that ever since upgrading to latest weechat, ruby scripts are all dead in the water

[flashcode]

@akerl: I played with the include of encoding.h, but no luck, I think the problem is not there.

The problem could be in weechat_ruby_code (in function weechat_plugin_init), the code used to load and eval scripts.
But I don't know what is wrong, so any help is still welcome for this issue.

[jkolo]

For me workaround/solution is to add to script (.weechat/ruby/<name_of_script>.rb) line require 'enc/encdb.so' as the first require

[gsingh93]

@jkolo's workaround works for me. Hopefully this gets a proper solution sometime soon.

[flashcode]

Yes it works with this workaround, but I'm not able to apply this workaround on the script loader (in weechat-ruby.c).
The enc/encdb.so should already be included.

[flashcode]

Ah, good news, just found a way to fix the problem by moving the include of enc/encdb.so just before evaluating the script code (before module_eval(lines)).
I'll make some tests and commit if it's OK.

[flashcode]

Please try with the latest commit, it should fix the problem.

Gosh, I didn't update in ages... on the bright side, I can confirm the fix works 😉
