Programming :: PyGTK: Send Output From A File Descriptor To A Textview?

Jul 22, 2010

Within PyGTK I'm using gobject.spawn_async to launch a bash script. I would like the output of that bash script to be displayed within my application. I have a textview set up to receive the text ...

Here are the commands that launch the program:

Code:
def run_command(command):
global keep_pulsing
keep_pulsing=True
(cpid, cstdin, cstdout, cstderr) = gobject.spawn_async(command,flags=gobject.SPAWN_DO_NOT_REAP_CHILD|gobject.SPAWN_STDERR_TO_DEV_NULL,standard_code....

Here are the two callback functions. But like I say ... I have no idea how to get that data from the 'cstdout' file descriptor into a textbuffer.

Code:
### THE FOLLOWING ARE GLOBALS:
textview = wTree.get_widget('textview1')
textbuffer=textview.get_buffer()
def update_textview_callback(fd, condition):
global keep_pulsing
if keep_pulsing:
progressbar.pulse()
code....

General :: Send The Output Of Send Command To A File?

Jan 20, 2011

in the middle of script, i need to send the output of (send command on line 8) to a file

#!/usr/bin/expect
spawn telnet 172.20.64.133
expect "ENTER USERNAM <"

[cod]....

i treid the below on line 8 :

1- send "show command;

" > logfile.txt : gives an error extra character after the "

2- logsave logfile.txt 'send "show command;

" ': error invalid command

3- i simply tried to send the output of the whole script to file logsave /home/logfile ./script : seems that logsave work under root only

4- ./script > logfile : the problem with this is that the output of echo or (read "enter your id") command will not be displayed on the screen (actually nothing will be displayed, i have to open the log file to see the output). is there any way to save the log of the "send" ? or to save the log of the complete script without hiding the output on the screen?

Programming :: What Does Closing A File Descriptor Mean

Mar 13, 2011

As we know, every process has a table with a file descriptor table, in which each entry contains a file pointer pointing to the corresponding file table which contains a v-node pointer pointing to the v-node table.

When closing a file descriptor, are all these data structure deleted?

Programming :: Create PyGTK Gnome Screensaver?

Dec 15, 2010

I have created a PyGTK app (a binary clock) that I would like to turn into a screensaver. I added the .desktop file to /usr/share/applications/screensavers/ but all I get when I select it is a black screen. On the GnomeScreensaver FAQ (here) it says to use a gsthemewindow as the toplevel window, but the libraries given are in C. Is there any way to:Import this C library to get access to this toplevel window, Convert this GTK+ C library to PyGTK, or use a pygtk app as a screensaver in some other way?

Debian Programming :: Implementing PyGtk For Python 3.3 In Wheezy

Sep 12, 2013

I run Wheezy Xfce 64-bit. I went through the Synaptic listings and added Python 3.3.2 and Tkinter for it, and that works fine; but for some reason PyGtk is available only for Python 2.7, not for Python 3.3, unless I'm just using the wrong way to try to find it. Is there a PyGtk available for Python 3.3 in Wheezy, and, if so, how do I install it and then import it once it's installed?

General :: Open Local File Error When Creating File Descriptor?

Sep 14, 2009

error message when I ran my program that I couldn't open my local file. I have two files first one is called client, second one is called server I am using named pipes to sent a message from client to the other file called server in client I used mknod() to create the two named pipes,one for read,one for write and created new thread in client using fork() spawned a child process that executed the server file both named pipes are opened the client file got the message from the user and sent it through the named pipes to the server file when the server receives the message , it needs to verfify it is correct in the server file, a local file descriptor is created to read and send this verifing message when it is not correct but I am getting an OPEN() error when I tried to open this shared local array buff and attach it to a file descriptor where the message is kept why do I get this error in server file

int main()
{
/*both named pipes are open*/

Programming :: Send File Through Raw Socket Using C Programming

Jul 23, 2010

I am currently doing a research on video transmission over wireless LAN. I tend to transmit my offline file (xx.svc) from server to client.It may sound stupid (since I have a very little knowledge about c programming and raw socket), but my biggest challenges is that when I want to write the file to the buffer, how actually to define/include the file at the programming coding? where I need to locate the file? Is it at the same folder with my c programming, or somewhere in the linuxinclude folder?

Can anyone just give a simple example on how to include a file and write it into a buffer before send it through raw socket.

Programming :: Sed - Save Output To File With Filename From Content Of Another File?

Feb 28, 2011

My employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Iïve named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:

sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.

Programming :: Send File With FTP From Small Version?

Feb 9, 2011

I have this problem.I need to do this:I got a small version of Linux installed in some small devices. These devices come from the provider with this small version of Linux installed.This devices should send data to some other machine in the internet. I have tested wput for this purpose with a PC which has an Ubuntu version 10 and it works fine. However, when I try wput in the small device, I get an error. It seems that the wput might need some libraries to work with the small version of Linux installed in the small device.The fact of using wput or not is optional. I just need being able to send files through ftp with this small version of Linux.The thing is that to be able to run wput in this small version of Linux, it seems that many of the needed libraries were missing. So what I did was just install all the needed libraries. But still the wput program fails in its first line.

General :: File Descriptor Redirection And Duplication?

Mar 3, 2010

i've checked the link, and it makes it better. but it doesn't include all the information. i'll continue searching the internet. However i have seen an example of creating a fd:

Code:
exec 5<&1
echo "TEST" >&5
exec 5>&-

as in the page, this was intended to redirect the stdout to the fd 5 and create it, and close it. i have the following questions:- what is exactly the meaning of second command? is it to redirect the command stdout "test" to the fd 5? and how i can see the contents of the fd 5? - in the first command, why the < is used instead if > and what is the difference between the below two commands as in the info bash *Redirection section It will be helpful if anyone could include a graph for file descriptor before and after different command execution.

Software :: Bad Tty & File Descriptor Error While Building RPM On F13

Dec 20, 2010

I have an FC13 x86_64 server and having trouble building RPMs, but I don't think it's specifically an RPM problem. I think it's a tty management or other type of problem.

When spec files have a "%files -f filelist.txt", which contains the list of files for the RPM, it calls the /usr/lib/check-files script, which sorts the files that are supposed to be in the RPM and compares them with the files that are in the built RPM before they are packaged.

The trouble is that the sort fails.

Here's the trace from the check-files script:

The above doesn't show that the output from sort is redirected into those /tmp files. The first sort succeeds because it reads data sent by the "find" in the same shell. The second sort fails because (I think) it cannot read data from stdin for some reason.

What could possibly cause this? I've checked various permissions, libraries, even used strace extensively, all of which is inconclusive.

This is one of my test server boxes, so this problem is something that I've caused, but I have no idea what.

libc controls input and output, correct? Could it somehow be a glibc problem, or a devpts problem? I can run a simple command and pipe it to sort with no problem. It appears to only be related to sub-shells.

I also replaced sort with cat and just tried to redirect stdin in that file to a temporary file, and that also fails.

I've tried running it with selinux disabled and that has no effect.

Programming :: How To Redirect ALL Output To (log) File?

Aug 6, 2010

I am again struggling to make a script work, but hey, it is fun, I am learning new things. I discovered the set -x option which was, for me, like the second coming. Still, what I am not able to do is redirect ALL output to a (log) file, including what is produced by the -x setting. Let's assume a very simple script:
Code: #!/bin/bash
set -x
source="/home/atelier/Bureau/"
ls -la $source and I am running it as . test.sh >> /var/log/test.rmcb.log

The result of ls goes inded into the log file, but the rest still shows on the console where I am running the script: Code: ++ source=/home/atelier/Bureau/
++ ls --color=auto -la /home/atelier/Bureau/ Is there a way to redirect EVERYTHING to the log file ?
