| Tularis | hey guys, I have a problem with Zope's security system. I'm trying to enable the re module in the PythonScript product, but I can't seem to enable it fully. Base methods work fine, but the subobjects don't. So I can match a string against a regexp, but I can't use any of the result object's methods for some weird reason. Could someone possibly enlighten me as to what I'm doing wrong? | 00:39 |
|---|---|---|
| Tularis | The script and error are on: http://paste.lisp.org/+30SK (and I'm using Zope 2.10.6) | 00:40 |
| Tularis | Tried quite a few things... but nothing seems to work for me :s | 00:40 |
| Tularis | Was hoping someone here could give me a hint :) | 00:40 |
| kosh | geeze I have not played with that stuff in a long while | 00:44 |
| kosh | let me look up what you need | 00:44 |
| Tularis | I was pretty sure a simple import re allow_module('re') would be enough | 00:47 |
| Tularis | but apparently it wasn't | 00:47 |
| kosh | not it has to do with allowing access to unprotected subobjects | 00:47 |
| Tularis | well, I did read that adding a | 00:48 |
| Tularis | re.__allow_access_to_unprotected_subobjects__ = 1 | 00:48 |
| Tularis | would allow access to them | 00:48 |
| Tularis | but that's also automatically set by allow_module() | 00:48 |
| Tularis | even a couple of simple: | 00:48 |
| Tularis | allow_type(type(re.compile(''))) | 00:49 |
| Tularis | allow_type(type(re.match('x','x'))) | 00:49 |
| Tularis | didn't work :( | 00:49 |
| kosh | normally what I do is just use an external method and have it do any security restricted things and just had a result back | 00:49 |
| kosh | I convert to a list or tuple to hand back and that works for json, csv and a bunch of other stuff | 00:49 |
| kosh | I never use regex for anything | 00:49 |
| Tularis | one of my site maintainers requested it; he recieves a list of adresses, and has to split them up into street, housenumber and any additional info after it | 00:51 |
| Tularis | easiest way would be using regexps | 00:51 |
| kosh | for what I would do is just create an external method that you give it a string and it hands back the street,housenumber,additional stuff | 00:52 |
| Tularis | I guess making it an external method would work... I was just hoping I could also give them access to regexps, so it would be eaier for em | 00:52 |
| Tularis | *easier | 00:52 |
| kosh | have you tried doing re.__allow_access_to_unprotected_subobjects__=1 ? | 00:52 |
| Tularis | yes, to no avail :( | 00:53 |
| Tularis | it's also part of the allow_module code, so it gets ran anyway | 00:53 |
| kosh | overall it looks like one of the sites that used to have the way to do this I can't find anymore | 00:55 |
| kosh | ah I think I know the problem | 00:57 |
| kosh | allow_module works for pure python modules but re actually has a lot of c code and it does not work for that | 00:58 |
| kosh | I think external methods will be the only way to do it | 00:58 |
| Tularis | hmm | 01:01 |
| Tularis | the strange thing is, this is even mentioned as an example in the PythonScripts source code :s | 01:01 |
| Tularis | http://svn.zope.org/Zope/branches/2.10/lib/python/Products/PythonScripts/module_access_examples.py?revision=68400&view=markup&pathrev=68400 | 01:01 |
| kosh | security changes have been made since then | 01:01 |
| kosh | I forgot which version it was where the python script security model was rebuilt entirely | 01:02 |
| Tularis | I see, too bad :( | 01:05 |
| Tularis | for me that is | 01:05 |
| Tularis | good thing security was enhanced obviously ;) | 01:05 |
| kosh | it is just not something I have run into, it turns out all of the stuff I have needed to allow access to works | 01:05 |
| Tularis | same here, but not with this so far... | 01:05 |
| kosh | and I will not being doing new web dev for much longer | 01:05 |
