...compared the performance of some application on both a Xen domU and a standard linux machine (where domU runs on a similar physical mahine), I notice the application runs faster on the domU than on the physical machine. Instrumenting the application code shows the application spends more time on popen() calls on domU than on the physical machine. I wonder if xenlinux does some special modification of the popen code to improve its performance than the original Linux popen code? Thanks in advance for your help.

I''ve got a client who''s recently been moved onto a CentOS4 machine from a 3.x and is writing: "It looks like there''s one remaining problem now; at several points in the PHP part of the dating software, C- binaries are called using popen(). The binaries work correct (tested at the command line with the proper arguments) The popen() retrieves the correct command (I''ve echo''d it) popen() returns true The pointer set by popen() is a valid resource. Yet, nothing happens; the binaries should always return output, put...

Howdy. I am trying to launch an external shell process from my Rails app using IO.popen. The process runs just fine when I am logged in as the user from the shell but when I run it from Rails, the task doesn''t run properly and the output is too truncated to see any errors. Anything special I need to worry about when running shell tasks this way? I have code like the follow...

Hi, My application uses popen to execute UNIX commands. After I replace rsh with ssh, it stopped working. I have made a test C code to reproduce the problem as attached in this email. In the test program, I called popen for ssh command and then pclose right away. I got the following error: kirk 588$ a.out Write failed f...

Hello, I''m trying to write a utility to run an external process and capture it''s stderr. It seems that IO.popen only lets me read the stdout. Any tips for how to read stderr?

I want to write a python script and visual interface to manage glusterfs, such as creating and deleting volumes.This can be easier to manage glusterfs? But,now ,I execute the glusterfs command using python's subprocess.popen function?such as subprocess.Popen(GLUSTER_CMD, shell=True,stdout=subprocess.PIPE, stderr=subprocess.PIPE)...... But this does not feel like a good program, Because it has a serious dependence on the shell Is there a python or c library/function to execute the glusterfs command?So I can develop a be...

Hi all, I am encountering the following crash-causing bug using popen on occasion. I haven''t been able to narrow it down yet, but I am curious if anyone else has seen it or may have more information for me: Workers::DviToPng::PipeProtocol > terminate called after throwing an instance of ''std::runtime_error'' > what(): unable to re...

As described on wkhtmltopdf Google group (http://code.google.com/p/wkhtmltopdf/issues/detail?id=162), I have a problem generating a PDF while using popen and wkhtmltopdf. wkhtmltopdf takes HTML code as input and ouputs a PDF file.

...o binaries instead of recompiling the whole Xen everytime, so what I do is just modifying this two binaries, recompile them with "make tools" and then copy them into /usr/lib64/xen/bin/ .

I''m looking to write a javascript heavy clientside program with a something serverside backend that connects to the free maxima math program. I have extensive knowledge of ruby on rails, so I would prefer to call Maxima with ruby, but I don''t know if this is even possible. Its fairly easy to call Maxima (with a lisp implementation) using ANSI C, it is a little less easy to
