python - How can I launch a background process in Pylons? -

-

I'm trying to write an application that will allow a user to initiate a long-running process ( 5-30 seconds). After this, the user should allow the production of the process to be checked as it has been prepared. Output will be required only for the user's current session so that no longer need to be stored for a long time. There are two questions about how this can be accomplished when availing the benefits of the Pylons framework:

  1. What is the best way to start the background process, such as a pilot controller with?

  2. What is the best way to get back the output of the background process? (Do I need to store output in sessions, data, etc. in the database?)

Edit: The problem is whether I have an order Launching a controller waiting for sub-publication to end before continuing, using the subprocess in an administrator, which shows the blank page to the user who loads until the process is completed Used to be. I want to be able to redirect the user to a status page immediately after starting subprocess, so that he can complete himself.

I have managed this problem in the past (long-running process on HTTP). Your Pilliance controller makes a system call to your second process (whatever data is required to pass it) and the second process immediately becomes a daemon, this system ends the call and your controller can come back.

My web applications typically release AJAX requests until it is complete until it is complete.

Have used.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
