Webrick & CGI programs on WinXP

A

Austin Ziegler

I'm attempting to get ruwiki running under WEBrick on Windows XP. It's not
working, so I am attempting with a very simple CGI script. Well, that isn't
working, either.

I'm starting WEBrick with:
----------------
#!/usr/local/bin/ruby
require 'webrick'
include WEBrick

s = HTTPServer.new:)Port => 2000, :DocumentRoot => Dir::pwd + "/htdocs")

# mount subdirectories
s.mount("/ruwiki", HTTPServlet::CGIHandler, "C:/Apps/Ruby18/bin/ruby.exe")

trap("INT"){ s.shutdown }
s.start
----------------

My CGI script is currently called hello.rb, but I've tried it as hello.cgi
as well and it doesn't work:
----------------
#!C:/Apps/Ruby18/bin/ruby.exe

# hello.pl -- my first perl script!

print "Content-type: text/html\n\n"

print <<"EOF"
<HTML>

<HEAD>
<TITLE>Hello, world!</TITLE>
</HEAD>

<BODY>
<H1>Hello, world!</H1>
</BODY>

</HTML>
EOF
----------------

Here's the error message:

WEBrick has too many UNIX-isms to work well on a microsoft platform,
I've got it working though.

In cgihandler.rb add ``<< ::Conifg::CONFIG['EXEEXT']'' to line 21, so
the correct name of the ruby interpreter is used.

I had to add quotes to line 22 to use the correct path, because my ruby
is installed in a non-standard location:

CGIRunner =3D "\"#{Ruby}\" \"#{Config::LIBDIR}/httpservlet/cgi_runner.rb\""

I had to start WEBrick with a CGIInterpreter:

s =3D WEBrick::HTTPServer.new:)CGIInterpreter =3D> "\"#{WEBrick::HTTPServle=
t::CGIHandler::Ruby}\"")

I was then able to use a CGI:

s.mount("/hi", WEBrick::HTTPServlet::CGIHandler. "cgi.rb")

where cgi.rb was:

print "content-type: text/plain\r\n\r\n"

puts "hi"

Could you apply the attached patch? And if same error
occurs again, please increase the sleep time. (Windows
doesn't allow deleting opened files. This patch makes it
delay to wait for exiting of child process.)

and try it.

require 'webrick'
include WEBrick
s = HTTPServer.new(
:port => 2000,
:DocumentRoot => Dir::pwd + "/htdocs",
:CGIInterpreter => "C:/Apps/Ruby18/bin/ruby.exe"
)
s.mount("/rwiki", HTTPServlet::FileHandler, "/path/of/script-dir")
s.start

When CGIHandler is mounted on server directly, third
argument of mount() is expexted to be a pathname of script.

s.mount("/rwiki", HTTPServlet::CGIHandler, "/path/of/script.cgi")

Yes, but I don't hope it;-)

I'll merge these fix. Thanks.

After merging Eric's and gotoyuzo's patches, the script runs ... but
produces a 500 error and nothing in the log. I had already pretty much
reached the decision to implement this as a servlet, but it seems that the
CGI interface on Windows still needs some work. I may look at it a bit later
-- I am more interested in getting RuWiki working with WEBrick in any way
that I can so that the possibilities for RuWiki are greater.

That is the same error that I get on Sun. So it looks like
you have at least put XP on par with Unix.

Could you get error message with ruby -v?

Good idea.
I get the following:

Exception `WEBrick::HTTPStatus::InternalServerError' at

ary = [ "", "\n", "foo: bar", "foo: bar\n", "foo:bar\n\n" ]
ary.each{|data|
a, b = data.split(/^[\xd\xa]+/on, 2)
p [ data, a, b ]
}

result is:

["", nil, nil]
["\n", "", ""]
["foo: bar", "foo: bar", nil]
["foo: bar\n", "foo: bar\n", nil]
["foo:bar\n\n", "foo:bar\n", ""]

It seems that output of CGI is empty or doesn't include
separator of headers and message-body.
It may be that WEBrick couldn't get CGI output correctly;-)
