[Trac] Problem with slow project listing.


We've got a strange slowdown issue with our projects root listing. 
Nothing else is effected. No individual project has a problem.

Pretty much a textbook setup:

        <Location "/projects">
                SetHandler mod_python
                PythonHandler trac.web.modpython_frontend
                PythonOption TracEnvParentDir "/var/trac"
                PythonOption TracUriRoot "/projects"
                SetEnv PYTHON_EGG_CACHE /tmp

        </Location>

Useful Tidbits:
Trac 10.4
We're using SSL. Problem does not seem SSL-specific.
We have 175 and counting projects.
We've got a couple custom plugins, nothing earth-shattering.

So what we're seeing happening, we think, is that mod_python is loading, 
over and over again, a bunch of plugins, for some unknown reason:

2008-03-31 17:12:20,126 Trac[__init__] DEBUG: Loading egg plugin 
navhider.filter from 
/usr/lib/python2.4/site-packages/TracNavHider-1.0-py2.4.egg

Thanks for your quick response!

MaxRequestsPerChild is set to 0 AFAIK.

I am sure that the messages are from the single request, as we are 
watching it happen on our staging server. We can see the same problem on 
production (which makes us want to fix this quickly).

Thanks

Perhaps use a different value for:

  SetEnv PYTHON_EGG_CACHE /tmp

Hi All
The reason is that I forgot to add

[Trac] how can I make sure user needs to log in before he can access trac?


Hi,

How can I make sure user needs to log in before he can access trac?  I
have tried this command, but i can see browser the code without
logging in.
 $ trac-admin /path/to/projenv permission remove anonymous '*'

Thank you for any help.

[Trac] How to display info on Wiki page in box to the right?


I'd like to display some text/links on the right side of a wiki page
in a separate box. I'd like it to look similar to how a
[[PageOutline]] or [[TOC()]] macro would look, just with arbitrary
wiki markup in it.

I keep thinking there must be a way to do this that I haven't seen,
but I haven't found any macros or processors either built-in or as
plugins that seem to have this feature built in.

Can someone help me out here?  Thanks!

You can use the NewsFlashMacro to accomplish this.

http://trac-hacks.org/wiki/NewsFlashMacro

Only difference I can think of from your request is that the box has a
green background. But it contains the functionality your looking.

Thanks!

I did figure out another way though that doesn't require any plugins
and allows a lot of flexibility. The DIV wiki processor does what we
need in conjunction with some standard trac css declarations. It works
in 0.11b2, I'm not sure if it'll work in older versions or not.

This adds a standard box to side (formatted just like a table on
contents box):

{{{
#!div class="wiki-toc"
This goes into a box on the side
}}}

You can tweak the appearance with a bit of CSS code:

{{{
#!div class="wiki-toc" style="background-color: #ffccff"
A second box with a different background color
}}}

Note that you can have more than one on the page and they line up next
to each other. One advantage of this method is that the default colors
and layout would match the standard layouts of the rest of your Trac
site.

does that works? if so it's new to me.

everytime I have done that I removed each permission in a different command.
