python - Activate a virtualenv via fabric as deploy user -

-

I want to run my clothes script locally, which in turn, log in to my server, user Switch to Deploy, Activate Projects. VirtualAnv, which will replace the project, and release the GIT bridge. 

  def git_pull (): sudo ('su deploy') # I need to switch to Virtualenwin run here ('Git pull')

Actually, the VirtualWrapper uses the workon command, which will keep the source of the active file and the postactivate file in the project folder. In this case, it seems that the clothes run from within the shell, the control gives up to the fabric, so I can not use the built-in bash source in the source $ ~ / .virtualenv / myvenv / bin / activate>

Someone has given an example and explanation how they did it?

Now, what can I do, which is a kundi, but works perfectly well * (This use assumes that you are using VirtualWeaver - which you should be - but you can easily mention the 'substituted' source at the place that you have mentioned, if not): 

  def work (): workon = 'workon myvenv & amp; Amp; Run (Kamon + 'GIT pull') run (Varkon + 'do other stuff, etc.')

This technique is used in fabric since version 1.0, so that you For example: 

  def function: With prefix ('version mywave'): run ('git pull') ('do other stuff, etc.')

* should be bound in cases where command1 & amp; Amp; Command2 approach can blow you up, like when Command1 fails ( command2 never runs) or if command1 is not saved properly and there are special shell characters in it.

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...

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...
