 Thanks Remy for the prompt response!

 We are currently running the Trac over Windows server. I tried giving
 the write access to the trac.ini to everyone, but still the same issue
 is occurring. Can anyone please guide me to the correct way of
 assigning write permissions to the trac.ini file?

 The section in httpd.conf file for more info -
 Location /trac
     SetHandler mod_python
     PythonInterpreter main_interpreter
     PythonHandler trac.web.modpython_frontend
     PythonOption TracEnvParentDir E:\\Trac_projects
     PythonOption TracUriRoot /trac
     PythonOption PYTHON_EGG_CACHE E:\\egg_cache\\.egg-cache
  /Location

Does anyone know how to make the Trac conf file writable by Apache on
the Windows server? Will creating global trac.ini inside Trac-source/
conf help in flushing the cached data?

Re: [Trac] About including jQuery UI in Trac ...

 For distributions such as Debian or Ubuntu it is very important

 package that is used by Trac, but also by other web applications.
 If e.g. a security bug is found in JQuery, we need only to update
 the JQuery package with a fixed version and do not need to care
 about Trac and e.g. half a dozen other packages.

While I understand (and agree with) the general idea, I wonder if that
situation really applies to jQuery (core, not jQuery UI, see below):

 - Maybe I'm a bit naive, but what security issues could be in a
JavaScript library? Security is provided by the browser, not the
libraries, isn't it?

 - Trac expects to find jquery.js in trac/htdocs/js. So in the Debian
packaging, you replace the file provided with Trac with a symlink to the
separately-packaged jquery.js?

 - Do you keep several versions of jQuery installed at the same time on
a system, and for every package you link to the required version?
Packaging jQuery with Trac (besides simplifying dependencies) ensures
that we can make changes to the Trac code required by a jQuery update in
sync with the update.

 If Trac would use an embedded copy of JQuery, why not also
 include Genshi, Pygments, PySQLite/PsycoPG etc.? I hope, you
 don't do that :~)

Certainly not. There's (at least) one difference with jQuery: it doesn't
have a standard packaging, and therefore no standard location in the
filesystem where we could easily find it. And even if it did, it's a
single file, so I guess it seemed simpler to just include it.

I also notice that Gentoo doesn't have a jQuery package (just a data
point, certainly not an authoritative argument).

This would probably be different for jQuery UI, though. I assume it
includes images for the UI controls, so the single file argument
drops. Does Debian package jQuery UI? How does it link it into the
packages that need it?

[Trac] Can't login after upgrading to 11.6

2009-12-23 Thread Michel Jung
Hi

I upgraded my Trac from 11.5 (I guess) to 11.6. Now, I can't login
anymore (see Traceback below). I had installed some plugins like
UserAdmin or however it was called (to allow users to register
themselves).
Couldn't find anything on google yet, except a 3 year old, solved trac-
ticket (http://trac.edgewall.org/ticket/5383). Any suggestions?

 Looking forward to your comments ;o)

 As one of the packagers of Trac for Debian I have to oppose.
 (Well, not strongly, but oppose.)

 For distributions such as Debian or Ubuntu it is very important
 not to duplicate software in the archive, mainly, but not only,
 for security reasons.

+1

 In any case, as Debian packager of Trac I would have to use the
 Debian JQuery package, not an embedded copy in the Trac archive.
 If, however, the JQuery version embedded in Trac and the one in
 Debian diverge, if Debian uses a newer version, I fear, that
 resulting problems would not have high priority, because the
 embedded copy works. Well, the risk is probably not so high,
 but in any case I would prefer to not include any 3rd party SW
 in the Trac release.


Which is cool from a packager perspective but, what about the
programmers outside the (great) Debian world ? They have to bundle
jQuery UI over and over in every plugin to ensure that it will work
everywhere ...


 If Trac would use an embedded copy of JQuery,
 why not also
 include Genshi, Pygments, PySQLite/PsycoPG etc.? I hope, you
 don't do that :~)


I agree with you about not including Py libs in trac package, but
perhaps we are talking about two different things. I am mentioning a
poor little JS lib bundled with Trac since a long time ago whereas all
you mention are Python libs . Isn't it possible to do for jQuery UI
(i.e. libjs-jquery-ui) the same thing you do (and I can't figure out
;o) when packaging Trac w/ jQuery (i.e. libjs-jquery) ?

@ Remy Blank

Q:
  -  Does Debian package jQuery UI? How does it link it into the
 packages that need it?

`libjs-jquery-ui`, and `libjs-jquery` is in recommends so I suppose
there's another copy inside Trac ?

I think it's a bit premature for 0.12. We don't have yet any use for 
jQuery UI in Trac itself, so if we would add it just for the plugins 
without a good internal use case, we will probably not do it correctly. 
Such an use case could be the date picker for the date fields in the 
custom query ... some attempts have been made, but nothing satisfying 
yet. Once 0.12 is out, hopefully someone will send a good patch.

Btw, I don't see it as a problem to bundle it with Trac. We would have 
our own copy, with a well tested version, so what? Debian or other 
packagers can decide to strip it out and add whatever hoops they want. 
It will then be up to them to ensure that in the end, the .js files will 
still be installed when doing a trac-admin env deploy folder. But 
for Windows for example, it would be silly to require a separate download.

So maybe for 0.12.1, once we have a good example usage in Trac core.

Ah, and o|;o) too ;-)

[Trac] Advanced use of Genshi substitutions using wiki docs

2009-12-23 Thread Olemis Lang
This one is about Genshi, but it's for a Trac plugin. Hope you don't mind ;o)

I'd like to do the following :

  1- Retrieve a text written using WikiFormatting. Wiki text contains
some Genshi template expressions (done !)
  2- Render the text as (X)HTML leaving template expressions intact (done !)
  3- Transform the text using a known dict as context , thus expanding
template expressions
  4- Insert that text in an specific place inside another «static» XML template
using same rendering context

Q:
  - Is there a way to pass the output of 2) directly to 4) ? I mean to have
something in the «static» template just like ${wiki_tx(text)} and
expand the
contents inside the wiki text too when transforming the «static» template

I thought I knew, but I either forgot or was dreaming ...

Re: [Trac] About including jQuery UI in Trac ...

2009-12-23 Thread W. Martin Borgert
Quoting Remy Blank remy.bl...@pobox.com:
  - Maybe I'm a bit naive, but what security issues could be in a
 JavaScript library? Security is provided by the browser, not the
 libraries, isn't it?

In the case of JavaScript, the code runs in the browser, so maybe
it could influence client-side security. But in any case, there
can be errors in jQuery that need fixes, and there is no need to
replace Trac plus other servers, if you can just update jQuery.

  - Trac expects to find jquery.js in trac/htdocs/js. So in the Debian
 packaging, you replace the file provided with Trac with a symlink to the
 separately-packaged jquery.js?

Yes.

  - Do you keep several versions of jQuery installed at the same time on
 a system, and for every package you link to the required version?

There is only one jQuery package in Debian. I hope, that no need
arises to keep multiple versions around. Debian could cope with
that (we have a lot of libraries etc. in multiple versions), but
currently this is not supported for the jQuery package.

 Packaging jQuery with Trac (besides simplifying dependencies) ensures
 that we can make changes to the Trac code required by a jQuery update in
 sync with the update.

This is also my fear: If jQuery is packaged with Trac, Trac will
maybe depend on a specific version of jQuery and it might be
harder for Debian and other distributions to make it work with
the version that is supported by the distribution. For jQuery
this is risk is probably very low, but it exists.

 I also notice that Gentoo doesn't have a jQuery package (just a data
 point, certainly not an authoritative argument).

I have a friend at Gentoo, I will immediately tell him, how much
better Debian and Ubuntu are, because we have this package :~)

 This would probably be different for jQuery UI, though. I assume it
 includes images for the UI controls, so the single file argument
 drops. Does Debian package jQuery UI? How does it link it into the
 packages that need it?

Currently we have in Debian:

libjs-jquery: 1.3.3
libjs-jquery-ui: 1.7.2
libjs-flot: 0.5

Any package that needs a JavaScript Library just symlinks to file
it needs. E.g. libjs-jquery provides (among others) the file
/usr/share/javascript/jquery/jquery.js
The Trac package has a symlink
/usr/share/pyshared/trac/htdocs/js/jquery.js
to the above file.

For Windows-Users it might better to have a kind of Trac meta-package,
which contains not only Trac and jQuery, but also other important
dependencies, i.e. Python libraries. Whenever I have to work with
Windows, I feel relieved, when there is an installer with all I need.

 harder for Debian and other distributions to make it work with
 the version that is supported by the distribution. For jQuery
 this is risk is probably very low, but it exists.


I am not an expert but I thought `apt` solved this kind of things if
e.g. jquery=1.2 was specified in dependencies. Then if there were
multiple versions then it selects =1.2.6 (probably multiple repos in
sources.list ...)

 I also notice that Gentoo doesn't have a jQuery package (just a data
 point, certainly not an authoritative argument).

 I have a friend at Gentoo, I will immediately tell him, how much
 better Debian and Ubuntu are, because we have this package :~)


lol

 This would probably be different for jQuery UI, though. I assume it
 includes images for the UI controls, so the single file argument
 drops. Does Debian package jQuery UI? How does it link it into the
 packages that need it?

 Currently we have in Debian:

 libjs-jquery: 1.3.3
 libjs-jquery-ui: 1.7.2

Hehehe ... and trac works with jquery 1.3.3. or 1.2.6 ? Well, probably
does not matter . The only thing that would be needed is a symlink to
compatible versions of jQuery + jQuery UI . In the end , major changes
are included by Debian packagers too , isn't it ?

In the end what programmers (me) care about is about relying on the
fact that jQuery UI is there and therefore they won't need to bundle
it with each plugin (and not all are in Debian ;o) . Whether it is a
symlink or another copy, it's just an implementation detail.

 libjs-flot: 0.5


cool !

 Any package that needs a JavaScript Library just symlinks to file
 it needs.

Love Debian !

RE: [Trac] About including jQuery UI in Trac ...

 Quoting Remy Blank remy.bl...@pobox.com:
   - Maybe I'm a bit naive, but what security issues could be in a
  JavaScript library? Security is provided by the browser, not the
  libraries, isn't it?
 
 In the case of JavaScript, the code runs in the browser, so maybe
 it could influence client-side security. But in any case, there
 can be errors in jQuery that need fixes, and there is no need to
 replace Trac plus other servers, if you can just update jQuery.
 
   - Trac expects to find jquery.js in trac/htdocs/js. So in the Debian
  packaging, you replace the file provided with Trac with a symlink to
 the
  separately-packaged jquery.js?
 
 Yes.
 
   - Do you keep several versions of jQuery installed at the same time
 on
  a system, and for every package you link to the required version?
 
 There is only one jQuery package in Debian. I hope, that no need
 arises to keep multiple versions around. Debian could cope with
 that (we have a lot of libraries etc. in multiple versions), but
 currently this is not supported for the jQuery package.
 
  Packaging jQuery with Trac (besides simplifying dependencies) ensures
  that we can make changes to the Trac code required by a jQuery update
 in
  sync with the update.
 
 This is also my fear: If jQuery is packaged with Trac, Trac will
 maybe depend on a specific version of jQuery and it might be
 harder for Debian and other distributions to make it work with
 the version that is supported by the distribution. For jQuery
 this is risk is probably very low, but it exists.

 Any package that needs a JavaScript Library just symlinks to file
 it needs. E.g. libjs-jquery provides (among others) the file
 /usr/share/javascript/jquery/jquery.js
 The Trac package has a symlink
 /usr/share/pyshared/trac/htdocs/js/jquery.js
 to the above file.
 
 For Windows-Users it might better to have a kind of Trac meta-package,
 which contains not only Trac and jQuery, but also other important
 dependencies, i.e. Python libraries. Whenever I have to work with
 Windows, I feel relieved, when there is an installer with all I need.

Just remember the alternative is that every plugin has its own copy. However
much work it might be to retrofit Trac to use a central version, it will be
much harder to do this for every plugin that wants to use jQuery UI.

No question: This would be worse.
