Hi guys! This is my first post on this list. I'd like have your opinion on how to safely implement WSGI on a production server. My benchmarks show no performance differences between our PHP and Python environments. I'm using mod_wsgi v3.4 with Apache 2.4. Is that ok or can it get faster? Thanks in advance.... more »

|
| |
Hi folks,
This questions may be asked several times already, but the development of relevant software continues day-for-day. For some time now I've been using xhtml2pdf [1] to generate PDF documents from HTML templates (which are rendered through my Django-based web application. This have been working for some time now but I'm constantly adding new templates and they are not looking like I want it (sometimes bold text is bold, sometimes not, layout issues, etc). I'd like to use something else than xhtml2pdf.... more »

How to make shutil.make_archive support symbol links?
|
| |
Hi comp.lang.python group,
I'm trying to make a zip archive with shutil.make_archive, but it seems that it doesn't support symbol links, after creating a archive with shutil.make_archive, all the symbol links would be lost.
What I want is something like `zip -y`, which "stores symbolic links as the link instead of the referenced file", is it possible to do in pure python? I also looked into the zipfile module, but it mentions no symbol links.... more »
