folks! I get the following error message and I have no idea what to do. Is this a already known net-ldap bug? I tried to update my gems and I already looked for further informations in the internet. The first part is ok, I get ally my data from my ldap database but this error occurs in the end.
/usr/local/lib/ruby/gems/1.9.1/gems/net-ldap-0.3.1/lib/net/ber/core_ext/string.rb:23:in

and here my code:
require 'rubygems'
require 'net/ldap'
ldap = Net::LDAP.new
ldap.host = 'xxxxxx'
ldap.authenticate "cn=admin, dc=xxxx, dc=xxxxx, dc=de", "xxxxx!"
#puts ldap.bind
if ldap.bind
# authentication succeeded
else
# authentication failed
# p ldap.get_operation_result
end
filter = Net::LDAP::Filter.eq("uid", "*")
treebase = "xxxxx, dc=xxxxxx, dc=de"
ldap.search(:base => treebase, :filter => filter) do |entry|
puts "DN: #{entry.dn}"
entry.each do |attribute, values|
puts " #{attribute}:"
values.each do |value|
puts " --->#{value}"
end
end
end
There are many encoding issues in v0.3.1 of net-ldap [1],[2],[3],[4]. Several patches are already merged, but sadly, this great project seems semi-abandoned and the changes aren't pushed out to rubygems. Using it directly from github has been working well for me, and if you're using bundler, it is as easy sticking something like this in your Gemfile:
gem "net-ldap", :git => "git://github.com/ruby-ldap/ruby-net-ldap.git", :ref => '8a182675f4'
1 - https://github.com/ruby-ldap/ruby-net-ldap/pull/41
2 - https://github.com/ruby-ldap/ruby-net-ldap/pull/44
3 - https://github.com/ruby-ldap/ruby-net-ldap/pull/64
4 - https://github.com/ruby-ldap/ruby-net-ldap/pull/55

I am following the very basic tutorial found here: http://guides.rubygems.org/make-your-own-gem/
hola_username.rb:
class Hola
def self.hi
puts "Hello world!"
end
end
hola_username.gemspec:
Gem::Specification.new do |s|
s.name = 'hola_username'
s.version = '0.0.0'
s.date = '2010-04-28'
s.summary = "Hola!"
s.description = "A simple hello world gem"
s.authors = ["Surname Lastname"]
s.email = 'me.me#gmail.com'
s.files = ["lib/hola_username.rb"]
s.homepage =
'http://rubygems.org/gems/hola_username'
s.license = 'MIT'
end
That really is all there is to the project.
I can build my gem with
gem build .\hola_username.gemspec
I have also tested it by importing and executing the hi function of the Hola class and it works:
PS E:\hola_username> gem install .\hola_username-0.0.0.gem
Successfully installed hola_username-0.0.0
Parsing documentation for hola_username-0.0.0
Done installing documentation for hola_username after 0 seconds
1 gem installed
&
irb(main):001:0> require 'hola_username'
=> true
irb(main):002:0> Hola.hi
Hello world!
=> nil
irb(main):003:0>
But when I try to
gem push .\hola_username-0.0.0.gem
I get:
ERROR: While executing gem ... (Psych::SyntaxError)
(): control characters are not allowed at line 1 column 1
Any ideas?
Edit: I am on a windows 10 machine using ruby 2.0.0p598
Edit v01: Anything I put after gem push will result in the above error, doesn't seem to be a problem with the sample rubygem.
Edit v02: My credentials file that was generated in the .gem folder however stars with hex characters: fffe2d002d00.. Which might be the ones causing trouble?
My credentials file in .gem folder was encoded with UCS2 - Little Endian and converting it to UTF without BOM did the trick.
Although I have absolutey no idea why..
The following code works in Ruby 1.9.3p-551
require "open-uri"
res = open("http://example.com/version").read
p res => {"buildNumber": 2496, "buildDate": "2015-09-29 11:18:02 +0200", "timestamp": 1443639212 }
In any Ruby version higher than 1.9.3 I get the following error;
from /Users/imac/.rbenv/versions/2.1.0/lib/ruby/2.1.0/net/http/response.rb:357:in `finish': incorrect header check (Zlib::DataError)
I need to use a higher version as this will be used in a Rails 4 app.
Any ideas for alternatives?
Turns out the gzip encoding is not accepted by default. Or at least that's what I'm guessing.
The following works.
res = open("http://someurl.com/version", "Accept-Encoding" => "plain").read
Interesting how this changed from Ruby 2.0.0+
Another neat solution for this.
require 'rest-client'
url = "http://example.com/version"
def get_response(url)
begin
return RestClient.get(url, {:accept => :json})
rescue RestClient::GatewayTimeout
"GatewayTimeout"
rescue RestClient::RequestTimeout
"RequestTimeout"
rescue SocketError
"SocketError"
end
end
p get_response(url)
# => "{\"buildNumber\": 2535, \"buildDate\": \"2015-09-30 17:41:42 +0200\", \"timestamp\": 1444085042 }"
Suppose I was trying crawl a website a skip a page that ended like so:
http://HIDDENWEBSITE.com/anonimize/index.php?page=press_and_news&subpage=20060117
I am currently using Anemone gem in Ruby to build the crawler. I am using the skip_links_like method but my pattern never seems to match. I am trying to make this as generic as possible so it isn't dependent on subpage but just =2105925 (the digits).
I have tried /=\d+$/ and /\?.*\d+$/ but it doesn't seem to be working.
This similar to Skipping web-pages with extension pdf, zip from crawling in Anemone but I can't make it worth with digits instead of extensions.
Also, testing on http://regexpal.com/ with the pattern =\d+$ will successfully match http://misc.com/test/index.php?page=news&subpage=20060118
EDIT:
Here is the entirety of my code. I wonder if anyone can see exactly what's wrong.
require 'anemone'
...
Anemone.crawl(url, :depth_limit => 3, :obey_robots_txt => true) do |anemone|
anemone.skip_links_like /\?.*\d+$/
anemone.on_every_page do |page|
pURL = page.url.to_s
puts "Now checking: " + pURL
bestGuess[pURL] = match_freq( manList, page.doc.inner_text )
puts "Successfully checked"
end
end
My output something like this:
...
Now checking: http://MISC.com/about_us/index.php?page=press_and_news&subpage=20110711
Successfully checked
...
Anemone.crawl(url, :depth_limit => 3, :obey_robots_txt => true, :skip_query_strings => true) do |anemone|
anemone.on_every_page do |page|
pURL = page.url.to_s
puts "Now checking: " + pURL
bestGuess[pURL] = match_freq( manList, page.doc.inner_text )
puts "Successfully checked"
end
end
Actually the /\?.*\d+$/ works:
~> irb
> all systems are go wirble/hirb/ap/show <
ruby-1.9.2-p180 :001 > "http://hiddenwebsite.com/anonimize/index.php?page=press_and_news&subpage=20060117".match /\?.*\d+$/
=> #<MatchData "?page=press_and_news&subpage=20060117">
There are a number of examples on the Web (such as http://techoctave.com/c7/posts/32-create-an-rss-feed-in-rails) showing how to make a nice RSS feed using Builder. The canonical template is something like this:
xml.instruct! :xml, :version => "1.0"
xml.rss :version => "2.0" do
xml.channel do
xml.title "Your Blog Title"
xml.description "A blog about software and chocolate"
xml.link posts_url
for post in #posts
xml.item do
xml.title post.title
xml.description post.content
xml.pubDate post.posted_at.to_s(:rfc822)
xml.link post_url(post)
xml.guid post_url(post)
end
end
end
This works fine in Rails 3.0.7. In Rails 3.1 Edge, every command seems to produce...
Rendered home/index.rss.builder (25.2ms)
Completed 500 Internal Server Error in 875ms
ActionView::Template::Error (wrong number of arguments (1 for 0)):
1: xml.instruct!(:xml, :encoding => "UTF-8")
2:
3: xml.rss :version => "2.0" do
4: xml.channel do
app/views/home/index.rss.builder:1:in `_app_views_home_index_rss_builder___2123990471_2215695900'
app/controllers/home_controller.rb:17:in `index'
app/controllers/home_controller.rb:11:in `index'
Rails 3.1.0.rc1 broke for me with this bug too, but only when using Ruby 1.8.7 - turns out it's a problem with .instruct!
As a temporary solution you could monkeypatch xchar.rb with the following (as suggested by the author of this post http://lists.alioth.debian.org/pipermail/pkg-ruby-extras-maintainers/2010-June/005411.html):
--- /home/prahal/xmlbase.rb.orig 2010-06-03 11:18:38.000000000 +0200
+++ /home/prahal/xmlbase.rb.new 2010-06-03 11:18:53.000000000 +0200
## -131,7 +131,11 ##
end
else
def _escape(text)
- text.to_xs((#encoding != 'utf-8' or $KCODE != 'UTF8'))
+ begin
+ text.to_xs((#encoding != 'utf-8' or $KCODE != 'UTF8'))
+ rescue
+ text.to_xs()
+ end
end
end
You will also get this error if you have both Builder 3.0 and fast_xs 0.8.0 installed (note that hpricot bundles fast_xs 0.8.0 also)
You can work around this with the following monkey patch in application.rb:
class String
alias_method :orig_fast_xs, :fast_xs
def fast_xs(ignore)
orig_fast_xs
end
end
I am writing some Ruby code, not Rails, and I need to handle something like this:
found 1 match
found 2 matches
I have Rails installed so maybe I might be able to add a require clause at the top of the script, but does anyone know of a RUBY method that pluralizes strings? Is there a class I can require that can deal with this if the script isn't Rails but I have Rails installed?
Edit: All of these answers were close but I checked off the one that got it working for me.
Try this method as a helper when writing Ruby, not Rails, code:
def pluralize(number, text)
return text.pluralize if number != 1
text
end
Actually all you need to do is
require 'active_support/inflector'
and that will extend the String type.
you can then do
"MyString".pluralize
which will return
"MyStrings"
for 2.3.5 try:
require 'rubygems'
require 'active_support/inflector'
should get it, if not try
sudo gem install activesupport
and then the requires.
Inflector is overkill for most situations.
def x(n, singular, plural=nil)
if n == 1
"1 #{singular}"
elsif plural
"#{n} #{plural}"
else
"#{n} #{singular}s"
end
end
Put this in common.rb, or wherever you like your general utility functions and...
require "common"
puts x(0, 'result') # 0 results
puts x(1, 'result') # 1 result
puts x(2, 'result') # 2 results
puts x(0, 'match', 'matches') # 0 matches
puts x(1, 'match', 'matches') # 1 match
puts x(2, 'match', 'matches') # 2 matches
I personally like the linguistics gem that is definitely not rails related.
# from it's frontpage
require 'linguistics'
Linguistics.use :en
"box".en.plural #=> "boxes"
"mouse".en.plural #=> "mice"
# etc
This works for me (using ruby 2.1.1 and actionpack 3.2.17):
~$ irb
>> require 'action_view'
=> true
>> include ActionView::Helpers::TextHelper
=> Object
>> pluralize(1, 'cat')
=> "1 cat"
>> pluralize(2, 'cat')
=> "2 cats"
require 'active_support'
require 'active_support/inflector'
inf = ActiveSupport::Inflector::Inflections.new
to get the inflector, not sure how you use it
my solution:
# Custom pluralize - will return text without the number as the default pluralize.
def cpluralize(number, text)
return text.pluralize if number != 1
return text.singularize if number == 1
end
So you can have 'review' returned if you call cpluralize(1, 'reviews')
Hope that helps.
I've defined a helper function for that, I use it for every user editable model's index view :
def ovyka_counter(array, name=nil, plural=nil)
name ||= array.first.class.human_name.downcase
pluralize(array.count, name, plural)
end
then you can call it from the view :
<% ovyka_counter #posts %>
for internationalization (i18n), you may then add this to your locale YAML files :
activerecord:
models:
post: "Conversation"
