django-phased's Issues

Performance penalty for large pages

When PhasedRenderMiddleware is turned on, rendering time grows very fast with size of the content that is outside of phased block.

For simple page that results in ~100 kB of HTML:

without PhasedRenderMiddleware in MIDDLEWARE_CLASSES is rendered below 0.1 second
with PhasedRenderMiddleware it takes over 20 seconds on my machine to render.

This slowdown is reproducible in many environments:

devserver; python 2.7.3; django 1.4.6, 1.5.2
apache 2.2.22; mod_wsgi 3.3; python 2.7.3; django 1.5.2
apache 2.2.15; mod_wsgi 3.2; python 2.6.6; django 1.5.2

Steps to reproduce this problem:

setup example project from django-phased repository
add long text to base.html template, outside phased block
e.g. {% for _ in ""|ljust:"10000" %} some text {% endfor %} just after <div id="body">
visit any page using base.html template e.g. /blog/
wait for page to appear

'WSGIRequest' object has no attribute 'user'

Hey, I am getting error 'WSGIRequest' object has no attribute 'user' when trying to use django-phased. It happens when I try to refresh a page that was just cached. If I go to another page and then return back to the previous page, it does not happen. I am not exactly sure how to fix this.

Here is the context processor that causes the issue:

def inbox(request):
    from models import Message
    if not request.is_ajax() and request.user.is_authenticated(): # the error occurs becaue I access request.user here
        try: member = request.user.member
        except: member = None
        return {'inbox_unread_count': Message.get_inbox_unread_count(member)}
    else:
        return {}

using phased with contrib.messages

I am trying to apply phased on a snippet where I render flash messages but It doesn't quite work. I get the messages printed on all the pages several times. It's like they are staying in session as not-yet-printed even though they have been already printed by second_pass_renderer.

Error with comments app

I got this error when I try to use phased with the comments forms to check if the user is authenticated:

'functools.partial' object has no attribute '__module__'

This is the code on the template:

{% load phased_tags %}
{% phased %}
{% load comments %}

{% if request.user.is_authenticated %}
<a href="/exit/">Exit</a>
{% render_comment_form for enq %}
{% else %}
<a href="/login/">login</a>
{% endif %}

{% endphased %}

Is there something wrong with the code?

Thanks!

Django-phased with i18n trans tag

Probably a known problem, but I couldn't see it in the docs anywhere.

If you try and use {% phased %} and the trans tag you get a TemplateSyntaxError: Invalid block tag: 'trans' error message.

Is there away around this?

This project needs a maintainer.

Hi,

This repository seems to lack maintenance, I propose myself as a new maintainer.

Could you give me the right to push in your repository or just transfer it on my account in github?

Thank you
