Speed up require on win32

[Alex 2k8]

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?

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.

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?

Hello, Robert

Your logs looks good.

And I also do not notice any slowdowns of require.

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

My version was

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

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.

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

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

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

Kind regards

robert

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...

Probably cygwin is not calling the same OS functions.

Yes, that's a likely explanation.

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

Kind regards

Hi, Robert

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.

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.
