[Trac] htacces / Authentication information not available
Hi Guys, I switched to trac two weeks ago and have been enjoying it alot! Unfortunatly i ran into a problem and i can't seem to find any info on it. If i log in i get the error message: Authentication information not available. I get this message after i loged in. If i use a nonsense login name it is redirecting me back to the login so i guess part of the login works as it recognizing my login credentials. The guys over at my hosting (dreamhost) told me to fix it by adding this to the htacess file: AuthType Basic AuthName Trac AuthUserFile /path/to/my/trac.passwd Require valid-user however, it seems there are still some things not completly right. First of all the logout function doesn't seem to work. Second, and more important, when i use a rss reader to read the feed it asks for my name and password but still wont retrive the feed. Anyone tips on what i'm doing wrong? -- You received this message because you are subscribed to the Google Groups Trac Users group. To post to this group, send email to trac-us...@googlegroups.com.

[Trac] Trac detected an internal error when displaying Timeline
Hi all,
I've installed TRAC and SVN.
It worked well since I updated data in the TRAC SQLite database in tickets.
Now, all features are running well except Timeline !
Trac encounters the following error.
I already searched in the TRAC ticket database and I found nothing about this
issue.
Oops...
Trac detected an internal error:
TypeError: coercing to Unicode: need string or buffer, NoneType found
This is probably a local installation issue.
Found a bug in Trac?
If you think this should work and you can reproduce the problem, you should
consider reporting this to the Trac team.
Before you do that, though, please first try searching
http://trac.edgewall.org/search?ticket=yesnoquickjump=1q=TypeError%3A+coercing+to+Unicode%3A+need+string+or+buffer%2C+NoneType+found
for similar issues, as it is quite likely that this problem has been reported
before. For questions about installation and configuration of Trac, please try
the mailing list http://trac.edgewall.org/wiki/MailingList instead of filing
a ticket.
Otherwise, please a new ticket at the Trac project site, where you can
describe the problem and explain how to reproduce it.

Hi all,
Finally, I found that some tickets had no summaries.
Adding a summary on these tickets solved the problem.

Re: [Trac] Macro for referencing values and do calculations
If you are calling eval() on a user-provided string you should assume they can run arbitrary code with the permissions of the webserver. This almost certainly means anyone with edit access can delete the Trac site, and probably do plenty of more subtly evil things. If you wouldn't give every one of your users root on the Trac machine, don't do this. If you want to make a single calculation system, PyParsing has one as an example. --Noah On Feb 19, 2010, at 5:04 AM, W.

Re: [Trac] Macro for referencing values and do calculations
Quoting Noah Kantrowitz n...@coderanger.net:
If you are calling eval() on a user-provided string you should
assume they can run arbitrary code with the permissions of the
webserver.
Even if I limit the available commands? I use:
eval(argument, {__builtins__: None}, CalcMacro._localdict)
_localdict contains some Python built-ins and math functions.
If you want to make a single calculation system, PyParsing has one
as an example.
Yes, PyParsing is really nice and capable.

Yes, don't do that. There's currently no sensible way to make eval()
safe (short of writing your own version). There was a kind of contest at
some point where people tried to write arbitrary programs using only a
single eval() (can't find the link ATM, but it was quite...
enlightening). And no, there doesn't seem to be a way to restrict the
available symbols. IIRC, you can always find a way to access __import__,
which gives you access to all the rest.

I see.
IIRC, you can always find a way to access __import__,

At least the naive way is blocked:
eval(__import__(), {__builtins__: None})
Traceback (most recent call last):
File stdin, line 1, in module
File string, line 1, in module
NameError: name '__import__' is not defined
Anyway, I will look into a PyParsing based solution.
Still, I'm more than curious to learn how to break eval(),
but this a Python issue, not a Trac one.
