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 <:((><

Any ideas?

To: djberg96 at gmail.com Dan, Thanks for your work on the win32util modules. I''ve created an expect-like library that allows one to easily script interactions with non-GUI applications.

Hi all, Well, what''s in CVS at the moment is what I''m planning on releasing tomorrow, unless anyone has any objection. Please test, check out the docs, etc. Let me know if there''s anything fatal I''m missing. Regards, Dan

...lution: None Priority: 3 Submitted By: John-Mason Shackelford (jpshackelford) Assigned to: Nobody (None) Summary: [open3] set $? and return Process::Status with block call Initial Comment: This is another version Samuel Tesla''s patch which sets $? and also returns the Process::Status when popen3/4 is called with a block (i.e. this patch merges changes from the two patches Samuel submitted). Note that this implementation is not thread-safe.

Hi all, I''m seeing strange behavior with net-ping on Windows, which uses win32-open3 (Open3.popen3) behind the scenes. Download (or checkout) net-ping and run this: ruby -Ilib test\tc_pingexternal.rb It looks like the test suite is running twice. What''s happening?

Hi all, I''ve got an initial version of Open3.popen3 checked into CVS, along with a test suite, a sample 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 dow...

...Open Resolution: None Priority: 4 Submitted By: Daniel Berger (djberg96) Assigned to: Park Heesob (phasis68) Summary: Allow win32-open3 to take a block Initial Comment: I think we should allow win32-open3''s methods to take a block in the way that the Unix open3 module works, e.g. Open3.popen3(cmd){ |cmd_in, cmd_out, cmd_err| # ... } Each pipe should be closed via ensure as open3.rb does. This keeps the API compatible with the current Ruby API, and is probably a better way to use the module in general (since the pipes are guaranteed to be closed at the end of the block). Regards,...

Hi, I am using backgroundrb to create a automated system of typo blogs.So, users can create new typo applications using web interface and all that jazz. Now..its working perfectly except one minor glitch. Since latest version of typo has a command called "typo", i simply use that command to install new typo app.And it works. def do_work(args) DIR =

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

So, just spent seven straight hours on this. I have a post-commit svn script that runs all my tests. Emails me if something goes wrong. One of the lines looks like: @output = `rake test RAILS_ENV=test` The output from the rspec tests don''t seem to appear in @output. Why would that be? Oddly enough, that only seems to happen when the script is ran from svn''s post-commit

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...

OK I know whats happening. Your while loop completes and calls kill on the worker before your task_progress controller method ever gets called> So the worker is deleted and when you try to access it from rails you get an error because there is no longer a worker at that job key. The kill method is meant to be used within a worker that you fire and forget. If you want to get the

...his messes things up. I control smbclient via popen4() in python2.1. I've found this strange placement in the prompt to be the reason my code isn't working, via running smbclient like this: c = popen2.Popen4("smbclient //machine/c -N | tee /tmp/smb_out.txt) And watching smb_out.txt (Popen3() acts the same way). Is this likely to be an issue with how python talks to the process ? I have not included a test case in this mail because it would make it longer than it already is, but can provide one. Note that when I talk to the smbclient myself (via starting one from a shell) it appears...

...ly be considered an error. That still leaves the SW_HIDE vs. SW_SHOW issue, though. (Possible solution) Create an Open3.show_window= method that accepts a boolean value. It would be the onus of the programmer to remember to set this to true if they want to create a GUI window of some sort using popen3 or popen4. Ok, I''m done thinking for a little while. :) Comments?

Just for kicks, I thought I''d give the following a shot: require "win32/process" require "open3" sin,sout,serr = Open3.popen3("echo %PATH%") p sout.gets p serr.gets Returns nil for both, but hey, at least it doesn''t crash. :) Dan
