pylint #110213 "No such message id W0704" when using Python 3.3 [validation pending]

I tried installing to a fresh 3.3 virtualenv. It seems to install okay, but when I run Pylint, it gives an error. I'm using Arch Linux. Install output and error message:

    I hit the same snag on Fedora 18 using virtualenvwrapper's mkvirtualenv to create the venv, workon venv, then pip install pylint.

  • 2012/12/21 12:57, written by anon

    Same here with ArchLinux (3.6.10-1-ARCH x86_64) and Python 3.3.0.

  • 2013/01/10 18:38, written by ToBeReplaced

    pylint-0.26.0 seems incompatible with CPython-3.3.0. The function `package_load` in pylint/checkers/__init__.py will not correctly load the checker modules, which is what is causing the bug in this thread. I hacked the file on my local copy to see if I could get it running, but I ran into a number of other issues before the rabbit hole got too deep.

    First, the TreeRebuilder(3k) in logilab-astng-0.24.1 does not implement methods for some of the nodes it needs. It is missing methods for `visit_try` and `visit_yieldfrom`. Patching those with dummies got me to an issue visit_with, where I had to give up.

  • 2013/01/13 15:05, written by anon

    I had the same problem with visit_try , visit_yieldfrom, and visit_with using Eclipse and pylint 0.26.0;python 3.3; astng 0.24.1; common 0.58.3.

    visit_yieldfrom and visit_with were resolved by manually downloading astng 0.24.1 from the python website and manually installing. Did the same with common. This version of 0.24.1 contains visit_with and visit_yieldfrom methods.
    I had tried using pip before.

    I also made a visit_try method in TreeBuilder and copied the visit_tryelse method body from TreeBuilder and that resolved that(not a good fix but one that made it start working).

    I also was getting the no module named* errors.
    I replaced this line in pylint.checkers package_load to fix(not ideal I think):
    #module = __import__(basename, globs, globs, None)
    import importlib
    module = importlib.import_module("pylint.checkers." + basename)

    I also loaded the src for common, astng, pylint and fixed some imports that eclipse said weren't working. Not sure if I needed to do this it was an early fix attempt. But try it if the above still doesn't fix it.
    Also there's a cmp method pylint.reporters __init__ diff_string that doesn't work with 3.# python. I found this workaround on some site:
    def cmp(a, b):
    return (a > b) - (a < b)

    Not sure if I really need this since I'm not sure I use reporters with eclipse since I turn off reports with --reports=n. Maybe reporters doesn't have anything to do with reports. Worth trying it out if the above doesn't fix it.

  • 2013/01/13 15:09, written by anon

    I meant TreeRebuilder in astng rebuilder.py in the above post.

  • 2013/01/15 03:55, written by anon

    Actually visit_yieldfrom isn't in astng. Though it just gives an error message and pylint still works I guess.

    Also the visit_try fix doesn't really fix anything it just allows pylint to not error out. I don't think try blocks will get processed correctly.

  • 2013/01/25 06:47, written by anon

    I was able to get visit_try to work with 3.3. Although it's not ideal it does pass the unit tests involved with testing try blocks. Even so, the unit tests didn't pick out every situation so you might have to add more fixes to different newnode attributes than the ones listed below.

    In astng rebuilder add:

    from _ast import Try

    In astng rebuilder TreeRebuilder class add:

    def try_fix(self , newnode, node, attr=""):
    newNodeBlock = []
    for child in getattr(node, attr):
        if isinstance(child, Try):
            newNodeBlock.extend(self.visit(child, newnode))
        else:
            newNodeBlock.append(self.visit(child, newnode))
    setattr(newnode, attr, newNodeBlock)

    In astng rebuilder TreeRebuilder class add:

    def visit_try(self, node, parent):
     newnodes = []
     if node.finalbody:
         newnodes.append(self.visit_tryfinally(node, parent))
     newnodes.append(self.visit_tryexcept(node, parent))
     return newnodes

    Now in astng rebuilder replace every instance of:

    newnode.body = [self.visit(child, newnode) for child in node.body]

    replace with:

    self.try_fix(newnode, node, 'body')

    newnode.handlers = [self.visit(child, newnode) for child in node.handlers]

    replace with:

    self.try_fix(newnode, node, 'handlers')

    newnode.orelse = [self.visit(child, newnode) for child in node.orelse]

    replace with:

    self.try_fix(newnode, node, 'orelse')
  • 2013/01/25 07:04, written by anon

    Another fix to astng rebuilder for python 3 only:

    In astng rebuilder TreeRebuilder visit_with function change all:
    node.context_expr
    replace with:
    node.items[0].context_expr

    Please stop adding python3.3 related bugs as comment in this thread, rather add new tickets. I've added the following tickets extracted from this thread:

    You will also find patches attached there, and I would be glad if you could test them.
