Cheeseshop needs mirrors
by Jon April 1, 2007

April 1, 2007

I'm a frequent helper in the IRC channel for the Pylons web framework. Pylons is installed from eggs using easy_install, and when Cheeseshop is down (or so slow it might as well be down), it gives a bad impression of our framework and Python in general. It took us half an hour to figure out how to bootstrap setuptools onto one person's machine, since ez_install.py sources from the cheeseshop, and even when we got that installed, bootstrapping the rest of Pylons was very troublesome. If something as widely used as eggs is going to have a single point of failure like the Cheeseshop, we can't have it going down. I'm sure there are other solutions, but my suggestion is simply to have mirrors. It works for Debian, after all.

saving Python process state for later debugging
by yossi.kreinin＠gmail.com April 1, 2007

April 1, 2007

Hi! Is there a way to save the state of a Python process for later inspection with a debugger? One way to do this is to dump core, but is the result usable for debugging with pdb (it can be debugged by gdb, which can inspect PyObjects in a CPython core, for example, but it's not much fun)? If there is no way to do this today, are there essential difficulties in implementing this on top of an OS support for "raw" core dumps? TIA, Yossi

Re: tag replacement in toxml()

Gabriel already answered the question: you need to add a 'b' element, which has a text child with the text 'problem'; this b element needs to be a sibling of the text node 'Here is the '. This still won't give you the output "Here is the <b>problem</>", as that will insert a closing tag. If you really want to produce the text '<?xml version="1.0" ?>\n<example><node><nodeTwo>Here is the <b>problem</></nodeTwo></node></example>' you cannot use an XML library to do so: this text is not well-formed XML (because </> is illegal syntax).

Unicode list
by Rehceb Rotkiv April 1, 2007

April 1, 2007

Hello, I have this little grep-like program: ++++++++++snip++++++++++ #!/usr/bin/python import sys import re pattern = sys.argv[1] inputfile = file(sys.argv[2], 'r') for line in inputfile: matches = re.findall(pattern, line) if matches: print matches ++++++++++snip++++++++++ Like this, the program prints some characters as strange escape sequences, which is due to the input file being encoded in utf-8: When I convert "re.findall..." to a string and wrap an "unicode()" around it, the matches get printed correctly. Is it possible to make "matches" unicode without saving it as a single string first? The function "unicode ()" seems only to work for strings. Or is there a general way of telling Python to abandon the ancient and evil land of iso-8859 for good and use utf-8 only? Regards, Rehceb

help with dates

April 1, 2007

I'm working on a website for some firefighters that want to be able to sign-up for overtime and I need some help figuring out a date related problem. Here's the scenario: Four groups of firefighters (group1, group2, group3, group4). Each group works a 24 hr shift. So group1 works April 1, group2 works April 2, group3 works April 3, group4 works April 4, group 1 works April 5, etc. It just keeps rolling like this forever into next year, etc. I need to come up with a methodology for the following:

Converting _node* to a Code object?
by Brendon Costa April 1, 2007

April 1, 2007

Hi All, I have an application with an embedded python interpreter and i need to get the embedded interpreter to "import" strangely named files as python modules. Anyhow the simple part of the question is: How do i convert a _node* object returned from: PyParser_SimpleParseStringFlagsFilename() into a code object i can use as a module to import with: PyImport_ExecCodeModule() I cant seem to find any documentation about this. If you are wondering why i want to do this, then you can read on and maybe there is a much better way to achieve what i am after. Thanks, Brendon ----- What i am trying to achieve ----- Basically i want to "import" using the python C API a module from various files which may have names that do not make valid python module names. In particular i have an embedded python interpreter that is used to apply a number of operations on some data based on a user supplied "suppressions file" (*.eds). This .eds file is just a python source file designed only to be used from within this application. Now the names of these suppression files usually matche that of a library or application to which they will apply to. For example: libstdc++.so.6.0.5 : has eds file: libstdc++.so.6.0.5.eds Now i want to have my code import this eds file as a python module so that i can then use it as any other standard python module. So i need to separate the name of the module from the name of the file. I was thinking for example for the above filename i would give it a module name like: libstdc___so_6_0_5 (The name is not important just that the above one is a valid module name from what i understand and it is based on the original name) So i have some random file: /foo/bar/lib/libstdc++.so.6.0.5.eds and i want to be able to import that as a module using the Python C API so native python code can access the module like: libstdc___so_6_0_5.PostCalculation() If you have any better method of doing this, i would love to know what it is. Thanks in advance for any help, Brendon.
