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...

...rying 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 than ap...

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.

...s 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. ---------------------------------------------------------------------- You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=413&aid=4121&group_id=85

Hi all, Aslak brought up a good point with regards to returning the pid for a popen4() method. As it stands now, it returns the pid of the shell rather than the pid of the process itself. However, my attempts to remove the COMSPEC stuff result in CreateProcess() failing with an error code of 2, i.e. "the system cannot find the file specified" - not too helpful. This is...

...ample program and some of the usual files (README, etc). This is just Park''s win32_popen package stripped down and modified to match the Open3 API. So far, so good. For the first release, I''ve decided that we should strip it down to popen3 only. We can always add popen2 and popen4 back in later. Also, I''ve dropped support for Win9x or ME. What''s left? Well, I need to write the docs yet. Also, I need to write some tests for the modes and generally figure out how modes work for popen3 on Win32. Any help or docs in that area appreciated. :) Also, I ha...

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.
