<straight-shoota> @szabgab Yes --fail-fast

<straight-shoota> In 1.1 this will actually be in the output of crystal spec --help. Because it's a runtime option, you currently only get the help by building and runnning the spec (crystal spec -- --help)

<hightower2> Are there some articles on multitenant http-based apps with Crystal?

@straight-shoota thanks

@szabgab

Is there a web site collecting videos about Crystal? Similar (or not) to https://pyvideo.org/ ?

George Dietrich

@Blacksmoke16

i doubt it

@alexherbo2

is there an equivalent to File.fnmatch from Ruby?

I want to test a glob string matches a file

thanks o/

@Blacksmoke16

is there a way to call a parent classes implementation of a method from a different method and when that parent method is also redefined in the child?

i.e. cant just do self.parent_method and super wont work because its not the same method

maybe ::parent_method would do it?

George Dietrich

@Blacksmoke16

nope

super.parent_method doesnt work either

@Blacksmoke16

looks like you're trying to read from a closed IO

Jonathan Silverman

@mixflame

before, it was nil errors

alright, i got it to connect, now im just back to the refusal to send bug

@mixflame

ERROR :Closing link: (97KAAAAEC@c-107-2-145-228.hsd1.co.comcast.net) [Registration timeout]

something to do with flush()?

George Dietrich

@Blacksmoke16

https://gist.github.com/mixflame/4e81d9083a02c9859ccc59c623b4d3c9#file-irc-cr-L79 is prob closing the socket so that when the other fibers execute it's closed

would be my guess without actually trying it

Chris Watson

@watzon

Seems likely. The code inside of the spawn is going to run asynchronously, so the .close is going to happen while the socket is still being accessed.

Jonathan Silverman

@mixflame

whoa thx

George Dietrich

@Blacksmoke16

looks like you got some non-ideal concurrency code going on

Jonathan Silverman

@mixflame

sorry guys even with that close disable the server still closes the link, there's a fail to write... i'll show the current code

https://gist.github.com/mixflame/ac368524b43075ab5768893290cc914d

the code has worked fine before without the SSL stuff bolted on...

trying to get it onto my irc network

George Dietrich

@Blacksmoke16

whats the error exactly again?

Jonathan Silverman

@mixflame

i'm back to this IRC based error, "ERROR :Closing link: (97KAAAAEC@c-107-2-145-228.hsd1.co.comcast.net) [Registration timeout]"

it happens when you don't do this fast enough:

```

  def login
    return unless @response_count == 3
    ssl_socket.as(OpenSSL::SSL::Socket::Client).unbuffered_write "PASS #{password}\r\n".to_slice
    ssl_socket.as(OpenSSL::SSL::Socket::Client).unbuffered_write "NICK #{nick}\r\n".to_slice
    ssl_socket.as(OpenSSL::SSL::Socket::Client).unbuffered_write "USER #{user} 8 * :#{user}\r\n".to_slice
    @logged_in = true
  end

George Dietrich

@Blacksmoke16

so at this point it sounds like it's a logic problem

Jonathan Silverman

@mixflame

surely

but the SSL socket simply isn't sending, i ran into this before

George Dietrich

@Blacksmoke16

do you need to use that socket directly versus just like HTTP::Client with tls enabled?

Jonathan Silverman

@mixflame

there's no TLS enable IRC socket in the crystal lang lib

it's speaking the Internet Relay Chat protocol

George Dietrich

@Blacksmoke16

ah right, and it's not HTTP based i take it?
