    Hello,

    I am trying to speedup the ruby1.8.6 'require' function for Windows.
    I've noticed that for file that successfully found FileMon reports too
    many such errors:

    DeviceIoControl, FAST IO DISALLOWED, Control: 0x12043
    DeviceIoControl, INVALID PARAMETER, Control: 0x12043

    One of the sources of these messages is:
    win32.c > rb_w32_fclose > is_socket > getsockopt

    I decided to reproduce this error. So, I wrote a test application linked
    with msvcr80-ruby18-static.lib:

    - - - - -
    FILE * fp = fopen(fname, "r");
    fclose(fp); // This results in rb_w32_fclose call.
    - - - - -

    But I do NOT get DeviceIoControl errors from my_test!

    So in short
    1. I get DeviceIoControl errors from rb_w32_fclose called by ruby.exe
    2. I do NOT get DeviceIoControl from rb_w32_fclose called by my_test.exe
    3. Errors come from the 'getsockopt' function.

    Can any one explain this, please? How can we avoid errors comming from
    ruby.exe?

    Thank you,
    - Alex

    Aha.. I forgot to call WSAStartup. No my_test.exe reports
    DeviceIoControl errors too.

    Btw, is not there any better alternative for 'win32.c > is_socket'
    function?

    I did this with cygwin's version of Ruby

    $ ruby -r a -e '1'

    There was an empty file a.rb in the current directory.

    I used Process Monitor 2.03 which is the successor of File Mon. I
    exported the trace filtered for the file name in field "Path" and
    "Process Name" for "ruby.exe". Please find the result attached. I did
    not find any DeviceIoControl which might be because of the other ruby
    version.

    HTH

    Cheers

    Hello, Robert

    Your logs looks good.

    I tested again in such environment:
    OS: Vista
    Process Monitor: 2.03
    Ruby: 1.8.6, 1.8.7, 1.9.0

    Used the same a.rb and command line as you. I got similar results for
    all ruby versions: every successfull read of a.rb is followed by ~60
    DeviceIoControl.

    I can't attach my CVS (posting from google site). How did you attach
    it?

    And I also do not notice any slowdowns of require.

    My version was

    ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-cygwin]

    Maybe it's in your environment? Do you somehow require "rubygems"?

    I sent it via Newsreader to the newsgroup comp.lang.ruby.

    Kind regards

    Hi, Robert

    > ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-cygwin]

    Probably cygwin is not calling the same OS functions.

    > Maybe it's in your environment? Do you somehow require "rubygems"?

    I tested on Windows Server 2003. And I tryed with/without rubygems -
    same results.

    Btw, I compiled ruby from sources, and changed rb_w32_fclose.

    //if (!is_socket(sock)) {
    if(1) {
    ...
    return fclose(fp);
    }

    The DeviceIoControl lines are gone. Then I checked the speed. I
    installed rails 2.2.2, then did:
    1. irb -rubygems
    2. s = Time.now; require 'activesupport'; e = Time.now; e.to_f - s.to_f

    For normal ruby results was:
    ~ 1.16 sec

    For patched ruby:
    ~ 1.00 sec

    Not a big advantage, but any way. Going to see if in more complex
    situations this can be more valuable...

    Yes, that's a likely explanation.

    I don't think it's worth the hassle. Just my 0.02EUR...

    Kind regards

    I see the same issue here, with MSVC builds. However, with MingW
    builds, i don't get the problem. The is_socket function you mention
    has been changed significantly in 1.9.1 anyway.

    This was not a patch, just an experiment. I simply commented a call to
    is_socket in rb_w32_fclose function. The 'require' works, but socket
    related functionality whould be broken :) And as for now I see no
    significant improvements, not going to continue.
