[Karrigell-main] Release of Karrigell-2.0.3

[<que...@fr...>]

(sent from another mail address - wanadoo seems to be on sourceforge blac=
k=20
list !?)

I've just released the version 2.0.3 of Karrigell. No major change this t=
ime=20
but a number of bug fixes, and a couple of new features :

*Bug fixes*

- add handling of urls without extensions in the debugger and Include

- in the name space, the field names with a leading undercore were not cl=
eaned=20
after script execution !

- restore original sys.path after script execution (once a script named=20
myScript.py had been imported from a directory, it was impossible to impo=
rt=20
another myScript.py from another directory)

- debug level could not be set to 0 !

- bug in update() method for objects in dbStorage

- error classes in gadflyStorage and sqliteStorage were not correctly set

- the query string of the caller url was not included in the qs generated=
 by=20
the join() method for Components

- removed the cache mechanism in Include**Component : event if the script=
 has=20
not changed, its output may have (search in a database for instance)

- when a script is cached, the query string attribute must be reset


* New features *

- in init file, in the "global" option of section "Server", specify Pytho=
n=20
scripts which will be imported before each script execution (allowing for=
 user-
defined values available for all scripts). this is an implentation of a=20
suggestion by Fred Pacquier

- better exception handling if parsing error in PIH scripts

- */terrific database management demo !/* I haven't documented it yet, an=
d it's=20
still bugged, but I'll go on working on it. Most of the bugs fixed in thi=
s=20
release were found as I worked on this demo. The basic idea is to describ=
e the=20
structure of a database in a text file, such as :

Title: Association

Danser
  Name
  Surname
  Birth: type=3Ddate
  Courses: type=3DCourse; multiple; view=3DTeacher,Day

Course
  Course number: type=3Dinteger
  Teacher: type=3DTeacher
  Day: type=3Ddate
  Hour start: type=3Dhour
  Hour end: type=3Dhour

Teacher
  Name
  Surname

Then a Python script generates all the Karrigell scripts needed to handle=
 the=20
base and the tables (here Danser, Course and Teacher) : you can browse th=
e=20
tables, add and remove items. All this uses gadflyStorage of course, maki=
ng the=20
scripts rather simple. An object can have attributes which are themselves=
=20
objects (here, a Danser instance has an attribute Courses, which is a lis=
t of=20
instances of the table Course)

Thanks for your advice, feedback and bug reports on this new version

A+
