[Karrigell-main] As Proxy Code

[Luis C. <lc...@ma...>]

For those interested, I added this configuration for using the Karrigell 
Web Server as a target for Apache Proxy.  Also, it works for ssl too, 
just add to ssl.conf.

CODE:
=======================================
LoadModule python_module modules/mod_python.so

SetHandler python-program
PythonHandler ApacheHandler

<VirtualHost *:80>
    ServerAdmin  x@yyy.zzz
    DocumentRoot /usr/local/apache2/htdocs
    SetHandler python-program
    PythonPath  "sys.path+['/usr/local/apache2/karri']"
    PythonHandler ApacheHandler
    PythonDebug on
    ServerName localhost.xyz.net


        ProxyRequests on

        <Proxy *>
            Order allow,deny
            Deny from none
            Allow from all

[Karrigell-main] Apache2 and Demo -- Missing variables?

[Luis C. <lc...@ma...>]

Hello:

Reading some of the comments on the forum, it sounds like apache or 
maybe just apache2 support is not there yet.  I'm a Zope user ( or was 
).  It is just to hard to do things with Zope once you get into it.  I 
prefer the KISS methology of Karrigell and I like writing my stuff in 
pure python too.

I got this trace back while running the demo and I think it is 
associated with the same problem you've been having before with Apache2.


Traceback (most recent call last):
  File "/usr/local/apache2/karri/Template.py", line 163, in render
    exec pythonCode in ns
  File "<string>", line 3, in ?
NameError: name '_content' is not defined

I am using the latest everything:

Apache2 - 2.0.53
mod_python - 3.1.4
Karrigell - 2.1.2 ( well there might be a later version than this, but I 
can't get to it yet ).

I'll be happy to send you other information that may be useful too 
(apache configure options ? ).

Also, there may be another way to skin this cat.  I have used this trick 
for years with Zope.  You setup your Karrigell web server behind your 
apache2 server by using the proxy command set of Apache.

So your web request comes in to Apache2 and then Apache2 redirects 
"transparently" to a local running Karrigell web server ( is there an 
acronym I can use for the web server?? ).

I'll try it to see if it works.

Luis.

[Karrigell-main] Web framework comparisons

[Pierre Q. <que...@wa...>]

I have found this Python web framework comparison :

http://the.taoofmac.com/space/blog/2005-02-13

The author seems to have a fairly good opinion on Karrigell (although he 
eventually chose Snakelets) :

-------------------------
This was the first "light" application server I looked at, and it kind 
of set the tone for the rest of my search. It was simple, neat and 
effective, although in need of a bit more polish.


        Pluses:

    * Templating, session, authentication, internationalization support.
    * Enough of a mix between object orientation and templating for
      real-life work.
    * Small code base.


        Minuses

    * Simplistic web server based on BaseHTTPServer. No gzip support, no
      HTTP <http://the.taoofmac.com/space/HTTP> 1.1 features, etc.
    * Small developer community (almost no activity on mailing-lists).
    * Documentation needs some work.

-----------------------------

With the last release the web server is hopefully less "simplistic" and 
gzip support is under way

I wonder what to do about the documentation ; do you have an opinion on 
how to improve it ? For instance, should I include a tutorial ?

Another point about comparisons : the PyWebOff project 
(http://pyre.third-bit.com/pyweb/) will be presented at the next Python 
Conference. 7 frameworks are reviewed, Karrigell is one of them, so this 
should give some more exposure to it - although it doesn't seem the 
project team has done much work on it so far

[Karrigell-main] Version 2.1.2 released

[Pierre Q. <que...@wa...>]

I have released version 2.1.2 of Karrigell. I've been waiting for weeks, 
hoping the statistics on sourceforge work again (I like to see how many 
people visit the page and download when I release a version) but it's 
still stopped on January,15th...

The main changes in this new release are : 
 
- a change in the default web server : instead of the SocketServer-based 
server, the one used when running python Karrigell.py is now an 
asyncore-based, asynchronous web server. From the measures I have made 
it it something like 30% faster than the previous one, and seems very 
stable. The SocketServer-based server can still be used, running python 
Karrigell_SocketServer.py 
- the If-Modified-Since header is now handled for static pages (patch by 
Luca Montecchiani) 
- the Content-Length header was missing 
- a new module called HTMLTags has been added, it can be used to 
generate HTML with Python functions. For instance, print A('Go 
there',href="foo.py") generates the HTML <A HREF="foo.py">Go there</A> 
- the Component features present in the previous versions has been 
removed. The concept of ready-to-use pieces of code still makes sense to 
me, but the implementation was ugly and bugged (trying to include 
components in other components failed). Perhaps it will come back in a 
future version, if I can find better ways to implement it 
- the small, all-Python KirbyBase database has been included in the 
package, with some demos already running with it (more support will be 
added in the next versions) 
- changes in Template.py to make the namespace for script execution cleaner

As usual, comments and bug fixes are welcome !

The "to do list" (http://www.karrigell.cafewiki.org/index.php?ToDoList) 
is updated, I am working on the gzip encoding

Pierre

Re: [Karrigell-main] Re: KarrigellRequestHandler.py bug ? Is this already known ?

[Pierre Q. <que...@wa...>]

I'm not sure, but this could be related to the proxy settings of IE. When you're at home, go to Tools/Internet options/Connections/LAN settings and uncheck the boxes so that IE doesn't look for proxies, then try to connect to http://127.0.0.1
Hope this helps,

[Karrigell-main] Re: KarrigellRequestHandler.py bug ? Is this already known ?

[Wayan W. <way...@gm...>]

I face this kind of problem too.  I use my machine ( Windows ) at home
where there is no network or internet. I started Karrigell an  it run
fine, but IE failed to access http://127.0.0.1/ ( with the message
exactly the same as Gabriele Giorgetti posted ), or if it even succeed
but it takes too long .

In mean time, if I use my machine at work ( I connected it to network
), I always succeed to access http://127.0.0.1/. If I disconnects the
cable from the NIC , it will failed with the same message.


Is it normal ?, Please help me. As I mostly doing my Python/Karrigell
thingy at home , and I want to working on Karrigell at home.

Thankyou.

Thanks! now i know what the problem was i guess.
I've been playing with modules quite a bit in my latest setup. And i got
strange errors: view a page, get an error msg, about some attribute of a
module not being available.
while True:
    Reload the page,
    not a problem.
    Reload the page
    error is back again

so i got rid of the file stuff in there, and it seems to work. Not that
i create modules on the fly, but some things sure seem like it :)
Especially if it's checked against the sys.path list ;) as i change that
list during page buildup.

Anyway, thanks for the explanation. Maybe this mail can be a pointer if
someone else has the same issues :)

[Karrigell-main] HTMLTags, a module to generate HTML in Python programs

[Pierre Q. <que...@wa...>]

I've never been satisfied with the way HTML code is produced by the 
modules in Karrigell, they all require the code to be written 
litterally, with long, often multi-line strings with opening and closing 
tags

I knew of HTMLGen but it was too big and a little too difficult for the 
scope of Karrigell ; so I finally wrote a very small module called 
HTMLTags (less than 100 lines of code), I've just published it on the 
Python Cookbook at 
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/366000

This is how it works :

The HTMLTags module defines a class for all the valid HTML tags, written in
 uppercase letters. To create a piece of HTML, the general syntax will be :

    t = TAG(innerHTML, key1=val1,key2=val2,...)

so that "print t" results in :

    <TAG key1="val1" key2="val2" ...>innerHTML</TAG>

For instance :

    print A('bar', href="foo") ==> <A href="foo">bar</A>

To generate HTML attributes without value, give them the value True :

    print OPTION('foo',SELECTED=True,value=5) ==> 
            <OPTION value="5" SELECTED>

For non-closing tags such as <IMG> or <BR>, the print statement does not 
generate the closing tag

The innerHTML argument can be an instance of an HTML class, so that you can nest 
tags, like this :

    print B(I('foo')) ==> <B><I>foo</I></B>

Instances of the HTML classes support the addition :

    print B('bar')+INPUT(name="bar") ==> <B>bar</B><INPUT name="bar">

and also repetition :

    print TH('&nbsp')*3 ==> <TD>&nbsp;</TD><TD>&nbsp;</TD><TD>&nbsp;</TD>

If you have a list of instances, you can't concatenate the items with 
sum(instanceList) because sum takes only numbers as arguments. So there is a 
function called Sum which will do the job :

    Sum([ TR(TD(i)+TD(i*i)) for i in range(100) ])

generates the rows of a table showing the squares of integers from 0 to 99

The innerHTML argument can be a string, but you can't concatenate a string and 
an instance of an HTML class, like in :

    H1('To be or ' + B('not to be'))

For this, use a class called TEXT, which will not generate any tag :

    H1(TEXT('To be or ') + B('not to be'))


A simple document can be produced by :

    print HTML( HEAD(TITLE('Test document')) +
        BODY(H1('This is a test document')+
             TEXT('First line')+BR()+
             TEXT('Second line')))

This will produce :

    <HTML>
    <HEAD>
    <TITLE>Test document</TITLE>
    </HEAD>
    <BODY>
    <H1>This is a test document</H1>
    First line
    <BR>
    Second line
    </BODY>
    </HTML>

If the document is more complex it is more readable to create the elements 
first, then to print the whole result in one instruction. For example :

stylesheet = LINK(rel="Stylesheet",href="doc.css")

head= HEAD(TITLE('Record collection')+stylesheet)
title = H1('My record collection')
rows = Sum ([TR(TD(rec.title,Class="title")+TD(rec.artist,Class="Artist")) 
	for rec in records])
table = TABLE(TR(TH('Title')+TH('Artist')) + rows)

print HTML(head + BODY(title + table))


I will include this module in the next release, and I've re-written the 
records management demo using it, I find it much cleaner

A bientot,
Pierre

Hello,

I started something like this. I wanted to make it seem a little like
ASP.NET's WebForms, at least in terms of API. I didn't complete it
though ... it has been standing around for a few months untouched (until
now). :-) I have to write validation tools and more controls.

However, maybe this will help:
http://toulouse.amber.org/archives/2003/09/03/python_form_and_validation_kits.html

Out of the list, I used formlib, which is decent, but I think needs a
little refactoring (this is why I started on my own project - to
approach forms differently.)

[Karrigell-main] Karrigell and missing HTTP Headers

[Gabriele G. <gab...@te...>]

Hi, I've noticed that the HTTP headers sent by Karrigell are very minimal.
Eg: The Content-Length is missing and if you download a file off 
Karrigell its size is unkown.
There are also problems with the pages cache...

Here is some code which deals with HTTP headers:

       if ctype.startswith('text/'):
            mode = 'r'
        else:
            mode = 'rb'
        try:
            f = open(path, mode)
        except IOError:
            self.send_error(404, "File not found")
            return None

        try:
            s = os.stat(path)
            # the os.stat modified time should be local
            # mdt is only used for comparisons below now
            mdt = time.gmtime(s[8])
            lastModified = date_time_string(s[8])
            size = str(s[6])
        except:
            mdt = None
            lastModified = None
            size = None

        ims = self.headers.getheader('if-modified-since')
        not_modified = 0
        if ims and mdt:
            # items 6, 7, 8 of parsedate will be usable
            # so those aren't used in the comparison below
            # see http://www.python.org/doc/current/lib/module-rfc822.html
            sdt = rfc822.parsedate(ims.split(';')[0])
            if mdt[:6] <= sdt[:6]:
                not_modified = 1
                # don't send back a file if 304
                f = None
        if not_modified:
            self.send_response(304)
        else:
            # note that send_response doesn't currently
            # accept an optional size parameter, so it can't
            # pass on the size to log_request
            # I've provided a backward-compatible version below that uses
            # a named argument
            self.send_response(200, size=size)
            if lastModified:
                self.send_header("Last-Modified", lastModified)
            if size:
                self.send_header("Content-Length", size)
            self.send_header("Content-type", ctype)


CherryPy does handle HTTP headers correctly for example, so you may want 
to take a look at the sources.

[Karrigell-main] Request for Form Framework in Karrigell

[NORA C. <nor...@gm...>]

Hallo

I wanted  a framework that makes it much easier to implement the 
processing for complicated/multipaged forms.
This  Form Framework to be  include widget classes that correspond to 
the various HTML form elements:
        * StringWidget (string): For entering a single line of text.
        * TextWidget (text): For entering multi-line strings.
        * PasswordWidget (password): Like StringWidget, but obscures 
what's being typed.
        * FileWidget (file): For uploading files.
        * CheckboxWidget (checkbox): A single checkbox.
        * SingleSelectWidget (single_select): A select box in which the 
user can choose one item.
        * MultipleSelectWidget (multiple_select): A select box in which 
the user can choose several items.
        * RadiobuttonsWidget (radiobuttons): A group of related radio 
buttons.
        * SubmitButtonWidget (submit_button): A submit button.
        * HiddenWidget (hidden): A hidden form field that isn't shown to 
the user.
        * IntWidget (int): A text widget that returns an integer value.
        * FloatWidget (float): A text widget that returns a float value.
Add several helper methods using sessionobject to render(), action(), 
process()   in workflow (next - submit - prev).

For python exist some FormKit. Has anyone experience?

[Karrigell-main] Re: Using Karrigell in Windows (best Praktices)

[Jim E. <jim...@gm...>]

One trick for running scripts as services under Windows is to create a
scheduled task (see under the Control Panel.)  If you use the schedule
option  'At system startup' you can effectively run Karrigell as a
service, or the 'At logon' option. You should uncheck the 'Stop task
if it runs for:' option under  Settings.

To incorporate logging, it's probably best to write a small command
file containing the text:

python Karrigell.py > info.txt 2> access.log

(as in Andrew's mail). e.g. save this as karrigell.cmd. Then call the
command file from the scheduled task.

Finally, create a local account for karrigell, and use this as the
schedule task account. The account should only be granted permissions
on the file system as required.

Hope this helps.

Cheers,
Jim

You can log stdout and stderr in dos like *nix:

python Karrigell.py 2> access.log

Will log most output into access.log. I say most, since it logs some 
things to stdout such as "Karrigell running on port (whatever)". If you 
really do want all that, then:

python Karrigell.py > info.txt 2> access.log

Will do the job.

for authentication, sessions, etc.

[Karrigell-main] Release of version 2.1.1

[Pierre Q. <que...@wa...>]

I have released version 2.1.1 today, and posted an entry in the Python 
Package Index. I'll release the next version as soon as the problem with 
Apache on Linux is fixed, but I wanted to advertise the "karrigell 
service" new feature, and this release includes a number of bug fixes 
that couldn't wait too long

The release notes are below :

The main new feature in this release is the introduction of a new kind 
of scripts,
    called "Karrigell services" : Python scripts where the functions can 
be called by a
    specific URL. That is, the url foo.ks/bar gets the result of 
function bar() in the
    script foo.ks. A small website can be built with just one "ks" 
script, instead of
    having several separate files. See the documentation and the examples
    One of these examples is "kwiki" : it's like a wiki, you can edit 
the pages, but
    instead of the strange markup in a textarea, kwiki uses a wysiwyg 
text editor, the
    excellent FCKEditor
    I have also introduced a couple of demos using the excellent 
KirbyBase 100% Python
    flat-file database (demos wiki_KirbyBase and kwiki_KirbyBase). 
KirbyBase itself is
    not (yet) included in this release but can be downloaded at
    http://www.netpromi.com/kirbybase.html
    Other minor features have been added :
    - in dbStorage : a new mode 'c' for opening (creates the base if it 
doesn't exist) ;
    no information table is created before an object can be inserted
    - I have spent some time to make the presentation of the home page, 
of some demos
    (especially gadflyAdmin) and of the documentation nicer (well, 
hopefully)
    A couple of bug fixes too :
    - a file not found results in a HTTP 404 error
    - debug and silent options were not correctly handled
    - cookie management was bugged
    As usual, comments and bug reports will be welcome !

Regards,
Pierre

I wrote a small homepages (extensive used sessionsobject, multipage  
Form and DB)  with "Karrigell services" in ver 2.1,

[Karrigell-main] Release of version 2.1

[Pierre Q. <que...@wa...>]

Hi all,

I've just released the version 2.1 of Karrigell

There are two main new features in this release :
1. the introduction of a new kind of scripts, called "Karrigell 
services" : Python scripts where the functions can be called by a 
specific URL. A small website can be built with just one "ks" script, 
instead of having several separate files. See the documentation and the 
examples

One of these examples is "kwiki" : it's like a wiki, you can edit the 
pages, but instead of the strange markup in a textarea, kwiki uses a 
wysiwyg text editor, the excellent FCKEditor

2. a beta version of persistence for session objects. If the 
"persistentSession" in the [Server] section of the configuration file is 
set, then all session objects will be store in a shelve file, instead of 
remaining in memory. Because of the rules that apply to serializing of 
Python objects, in this version only built-in types can be stored as 
attributes to the session object when the session is persistent. I have 
rewritten all the demos so that they work in all cases

This is introduced to solve problems of session handling that occur with 
Apache on Linux, but I haven't a Linux machine so I couldn't test it ; 
may I ask all readers who have this configuration to test the persistent 
session option (you must change the option in Karrigell.ini to 1) and 
tell me if it works ?

Other minor features have been added :
- in dbStorage : a new mode 'c' for opening (creates the base if it 
doesn't exist) ; no information table is created before an object can be 
inserted
- I have spent some time to make the presentation of the home page, of 
some demos (especially gadflyAdmin) and of the documentation nicer 
(well, hopefully)

A couple of bug fixes too :
- a file not found results in a HTTP 404 error
- debug and silent options were not correctly handled
