Oct. 1, 2004

Hi I want to dynamically generate a graph in python that would be displayable on a web page. What would be the best way to do this? The reason I want to do this, is because I am making a program to convert data from scientic probes into web pages. I have been able to do every thing except the graph generation. Your help would be much appriciated --- Tim Henderson

No more command history with cursor keys
by Chris Oct. 1, 2004

Oct. 1, 2004

Since I've installed (from sources) Python 2.3.4 on SuSE 8.2 the command history is not working anymore. When I press the cursor keys I get ^[[A or ^[[B .... I also tried to install IPython but the same problem is there. What's wrong? Chris

Avoiding shell metacharacters in os.popen
by Nick Craig-Wood Oct. 1, 2004

Oct. 1, 2004

I'm trying to avoid using shell metacharacters in os.popen in a portable fashion. os.popen() only seems to take a string as the command which would need tricky quoting. os.popen2() can take a string or a list - the relevant code in Unix python (in popen2.py) being... def _run_child(self, cmd): if isinstance(cmd, basestring): cmd = ['/bin/sh', '-c', cmd] for i in range(3, MAXFD): try: os.close(i) except OSError: pass try: os.execvp(cmd[0], cmd) finally: os._exit(1) This is perfect behaviour as far as I'm concerned - if you pass a list it doesn't go through the shell and if you pass a string it does. eg w, r = os.popen2(["ls", "-l"]) r.read() This leads on to my questions :- 1) is this behaviour (string vs list) of popen2 intentional? Its not documented anywhere and it doesn't work under Windows (gives "TypeError: popen2() argument 1 must be string, not list") 2) is there anything similar for os.popen() planned? 3) is there an equivalent to the perl quotemeta() command. This quotes meta-characters in a string for use in the shell. Here is a suitable definition for Unix, but I don't think that \ quoting works in Windows cmd = re.sub(r"(\W)", r"\\\1", cmd) Avoiding shell metacharacter attacks is a must for secure programs. Python does pretty well with its os.exec* and os.spawn* functions, but seems to be lacking in the os.popen* department! Any insights appreciated! -- Nick Craig-Wood <nick(a)craig-wood.com> -- http://www.craig-wood.com/nick
