similar to: mmap and faster IO?

Hi all, Ruby 1.8.1 (hand built, not the installer) Windows 2000 I was just playing with win32-mmap. I tried running the test_server.rb and test_client.rb. I started the server, which seems to be fine, but when I run the client I get this: C:\eclipse\workspace\win32-mmap-0.1.0\test>ruby test_client.rb C:/ruby/lib/ruby/1.8/ftools.rb:23:in `initialize'': Permission denied -

Hi all, This is odd. It looks to me like we have all 4 variations of memcpy set in Windows::MSVCRT::Buffer but somehow this one creeps up. I actually noticed it in a few cases with that earlier mmap sub/replace example, but I wasn''t sure what was happening. Note that windows-api 0.2.3 and windows-pr-0.8.3 are the latest versions in CVS, but this happens with windows-api-0.2.2 and

Hi all, I realized the current implmentation has a problem - you can only get the last value set? I realized, after looking at the old C code, that it actually stores values in a hash and marshals the hash, not the values themselves. That seemed clunky to me, though. I thought it would be more interesting if we just marshalled the entire mmap object and passed that back and forth.

I just tried running tc_mmap.rb and noticed that something rather curious seems to happen. The call to Mmap.new in setup seems to cause the test suite to just exit without ever actually running the tests. I reduced the test suite to just this bit of code. This works, although the final test (TypeError) does not pass - no exception in thrown. This is 1.8.1 on Win2k. Any ideas? Dan PS - I

Hi all, I was looking at win32-mmap today. I thought it might be worth it to rewrite this one as pure Ruby. In the process, I decided I don''t really like the current API very much. Just feels too clunky and not very friendly. I think we followed Win32::MMF too closely. Anyway, I have a very preliminary version in CVS that I was hoping folks could take a look at and comment on.

Hello Chad, I installed and tried out rubygems for one of the win32-utils projects named win32-mmap. This is on Win XP (Home). Here is how I did it but got some errors (see at the end). I must be doing something wrong. Please help ... -- Shashank #------------------------------------------------------------ require ''rubygems'' spec = Gem::Specification.new do |s|

Hi all, I have committed win32-mmap package. It is similar to mmap or shared memory of unix Basically, it can be used for variable sharing like this In server side ================================== m = Mmap.new a = 1 m.setvar("a",a) =================================== In client side ================================== m = Mmap.new(''reuse''=>true) a =

Hi all, I''ve been going through the various IPC modules for Win32Utils and converting them to pure Ruby. I''m almost done with win32-mutex, but I can''t get the example to work. I keep getting this error: C:/Documents and Settings/djberge/workspace/win32-mutex/examples/mutex_test.rb:41: undefined method `+'' for nil:NilClass (NoMethodError) from

Hi all, At RubyConf this year I talked about win32-mmap with Patrick Hurley and Ara Howard. Ara mentioned that Guy''s version of mmap (for Unix) contains some string-like methods that let you access pieces of the view like a string. Patrick and I came up with this (which requires the latest windows-pr in cvs so that we can use a more flexible version of memcpy, as well as some

Hi all, I''ve got the latest win32-mmap code checked into CVS. Unfortunately, it seems that I''m not able to open an existing mapping and retrieve set data. Below is a simple example that seems like it ought to work but doesn''t. Any ideas? # map1.rb require ''win32/mmap'' include Win32 mmap = MMap.new(:name => ''alpha'', :size

Oops - just realized that there aren''t accessors for namespace, swapfile, size, etc. Should we add them? Or don''t we want to because then it might become confusing as to whether those values were "shared"?

I suggest getting rid of the hash style arguments fior new() for this package. In this particular case, you already have a class and accessors, so you can just use the yield trick, e.g. rb_yield(self) if rb_block_given_p(). Thus you can do: mm = Mmap.new do |m| m.namespace = file m.swapfile = sfile m.size = 1024 end Looks just as nice, and is a lot less code on the C side of

Hi all, Since I didn''t get any takers on the win32-ole rewrite I thought I''d take a stab at starting it. Here''s what I''ve got so far (along with some extra constants in Windows::COM only in CVS), but the call to CoCreateInstance() isn''t working. I''m not sure if I''m dealing with the IDispatch interface properly: # win32/ole.rb require

Hello Guys, I''m trying to get this working: t = Thread.new { while true puts "printing a line" sleep 2 end } gets t.exit puts "exiting" As you see, the idea is get multiple "printing a line" until a hit enter. The thing is this is a known problem for 1.8 on win32. I tried both mingw, VC6 and VC8 with the same results. Saw a post

Excellent! Like I said, I really need to do some code cleanup.
