[Modeling-users] problem with qualifier parser?

[John L. <jo...@vi...>]

Sender: John Lenton <jo...@ma...>

Hi there, long time no see :)

First, sorry for my delay with the cimarron example. I've had to stop
working on cimarron for a while...

Now I'm working with Modeling in zope, and I seem to have come across
a bug... and I'm hoping there's an easy fix (or that it's already
fixed and I've just not seen it on sourceforge :p).

    $ python
    Python 2.3.3 (#2, Feb 24 2004, 09:29:20)=20
    [GCC 3.3.3 (Debian)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> from Modeling.EditingContext import EditingContext
    >>> ec=3DEditingContext()
    >>> ec.fetch('foo', 'orbit > 3')
    Traceback (most recent call last):
      File "<stdin>", line 1, in ?
      File "/usr/lib/python2.3/site-packages/Modeling/EditingContext.py", l=

        qualifier=3DqualifierWithQualifierFormat(qualifier)
      File "/usr/lib/python2.3/site-packages/Modeling/Qualifier.py", line 1=
29, in qualifierWithQualifierFormat
        return QualifierParser.qualifierWithQualifierFormat(expression)
      File "/usr/lib/python2.3/site-packages/Modeling/QualifierParser.py", =
line 550, in qualifierWithQualifierFormat
        _parse=3Dparse(sc)
      File "/usr/lib/python2.3/site-packages/Modeling/QualifierParser.py", =
line 417, in parse
        return parser.parse(tokens)
      File "/usr/lib/python2.3/site-packages/spark.py", line 204, in parse
        self.error(tokens[i-1])
      File "/usr/lib/python2.3/site-packages/Modeling/QualifierParser.py", =
line 261, in error
        raise ValueError, "Syntax error near token: `%s'" % token
    ValueError: Syntax error near token: `<Token OR>'

actually there's the same problem with any token: OR, AND, IN, or
NOT. Is this a known problem in spark? is my spark version wrong?
spark is 0.6.1, Modeling is 0.9-pre-16-patch892454.

Not a problem, 'having a hard time here as well :)

This is a bug, unfortunately not fixed on sf yet :/  I'll have a look at it
tonite. In the meantime you can build the same qualifier by hand:

  >>> from Modeling.Qualifier import *
  >>> q=3DKeyValueQualifier('foo', QualifierOperatorGreaterThan, 3)
  >>> print q
  (foo>3)
  >>> ec.fetch('foo', q)

You can have a look at test_Qualifier.py for other examples.

        HTH,

        Hi John and all,

  You'll find a patch solving the problem along w/ the corresponding
  unittests at sf.net, bug #938096:

https://sourceforge.net/tracker/index.php?func=3Ddetail&aid=3D938096&group_=
id=3D58935&atid=3D489335

        Thanks for reporting!

PS for Yannick: I still did not find the time to investigate any further
  about GNU Arch, but I will, this looks interesting (not to say about
  the new name for the framework...!-). Any comparison w/ subversion,
  BTW?
