...odeforpeople/ http://www.codeforpeople.com/lib/ruby/ SYNOPSIS open child process with handles on pid, stdin, stdout, and stderr: manage child processes and their io handles easily. HISTORY 0.5.0: - on the suggestion of tim pease (thanks tim!), i added timeout features to open4. the command run may have an overall timeout and individual timeouts set for each of the io handles. for example cmd = ''command_that_produce_out_at_one_second_intervals'' open4.spawn cmd, :stdout_timeout => 2 or cmd = ''comm...

...I am trying to start a rails webrick server programmatically. I want the console for that server to be shown. I earlier decided on using win32-open3 module as it provides me with flexibility to keep track of running of processes. I use following call to start webrick server, input, out, err, pid = Open4.popen4("ruby homedir/script/server -p 3001", mode=''t'',show=true) webrick server does get started but with no console; how do make the console visible. The reason I want the console to be up is because I have observed that rails applications run using console are faster...

Open3.popen3 returns the pid as well as the in, out, and err streams. I thought only the streams were supposed to be returned. Thanks -- Nathaniel <:((><

...i all, The topic of creating a unified API for open3 for Windows came up at RubyConf 2004 this year. Park, I was wondering if you would mind if we modified win32_popen so that the API matches the open3 library that ships with Ruby. This also means deciding whether or not to leave in the open2, open4, and posix stuff. I guess it doesn''t hurt to leave this in, although Open3.open4 seems a bit off ;) I suppose we could argue that "Open3" was a poorly chosen module name, but it''s too late now I think. Also, I had some trouble with win32_popen on XP Home although i...

Hi all, Just wanted to let you know that I released 0.3.1 last night. This addresses Bug #712 and incorporates Patches #1087 and #1137 (thanks Aslak). I''ll try to get an open4 implementation out this weekend, though I noticed that Aslak''s patch is different than what Park originally had, so I''ll have to decide which I prefer, or if they can be blended somehow. Regards, Dan

...it status Initial Comment: The UNIX Open3 sets the global $? to a Process::Status object so that one can read the exit status of the sub process. It seems that one is not supposed to fiddle with /that/ variable, but we can make our own. This patch adds a #last_status method to both the Open3 and Open4 modules that returns a Process::Status object that is set when the pipes are closed (similarly to how Ruby does it in io.c). I also made popen3 and popen4 return the object when they''re called with a block. I figured it was as neat idea. -------------------------------------------------...

In my previous mail the last line was supposed to be: "It turns out I probably won''t use fork unless support FOR STREAMS is added to it." aslak

Hi, I have an RoR application(parent) which is use to kick off other RoR applications(ajax scaffold based). I use win32-process Open4.popen4() to start the RoR applications. Untill recently I was using normal scaffold feature of Rails, and recently I migrated to Ajax Scaffold; After moving on to Ajax scaffold, when I try to start a RoR from my parent RoR, the application do get started, when I fire a request to get me the list pa...

I''ve added another patch for the popen3 library which sets $? and adds Process::Status a return when popen3/4 is called with a block thus making it closer to the Open4. This is a merge of a couple of patches previously submitted by Samuel Tesla. http://rubyforge.org/tracker/index.php?func=detail&aid=4603&group_id=85&atid=413 Note that this implementation is not thread-safe (as is demonstrated by sample code I''ve provided.)

hi, i want to make application that run a process automatically after server starts completely. I have explore and find popen4 gem which provides this facility. I have installed a gem but there is some problem while executing the ruby program. The error is like * <internal:lib/rubygems/custom_require>:29:in `require'': no such file to load -- win32/open3 (LoadError)* * from <internal:lib/rubygems/c...

hi all, is there a way to use fork with redirected streams? i mean in a similar way that ruby''s standard open3 does it. i''d like to be able to read the stdout/stdin/stderr streams from the forked ruby process in the parent process. cheers, aslak

If my Rails server has been sitting idle for a while, it does not respond to new requests. What is the best way to troubleshoot something like that.
