automagic bome header at start of utf16 content?
by Jürgen Herrmann 08 Jan '09

08 Jan '09

hello! i'm debugging a problem with our licence generation application. it spits out a ini file for our actual licence generator program (windows exe). to maintain backwards compatibility with an older version i try to encode the content windows-1252 if possibly, utf16 otherwise. on top of the method id do somthing like this: REQUEST.RESPONSE.setHeader('Content-Type', 'x-limiall-ini') REQUEST.RESPONSE.setHeader('Content-Disposition', 'attachment; filename=bla.blub') lines is a list of unicode strings. then i do: try: return '\r\n'.join(lines).encode('windows-1252') except UnicodeEncodeError: return '\r\n'.join(lines).encode('utf16') if there are unicode chars in the strings, that cannot be encoded in windows-1252, i get a file with a correct BOM header at the start ('\xFF\xFE'), which is exactly what we need. but i wonder where it comes from. i already sent the request directly to the zope server omitting our apache proxy and monitored traffic with wireshark. the com header comes from zope. i did not find anything in zope's code that heuristically finds out this is utf16 content and prepends the BOM header. so i'm a bit confused where zope takes it's wisdom from :) anybody? best regards, jürgen herrmann

Hi all, I need to set-up page with anonymous access with some informations from site, where are authorized access only. This page call dtml method list_robot from authorized site, from where are called other authorized methods and documents. From authorized site list_robot works, of course. Site structure: domain.com/authorized_pages.htm domain.com/public/index_html I was set-up to allow view etc for anonymous (and for all users) in security tab for "public" folder, index_html have defined proxy role "manager" and I am still not able to get content from authorized site content. And it still could not get DTML document js_lib (it is called as <dtml-var js_lib>) from authorized site. If I was comment js_lib calling, then it fails that used ZSQL method does not exist... Error Type: KeyError Error Value: js_lib This resource may be trying to reference a nonexistent object or variable js_lib. Traceback (innermost last): File /var/zope/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /var/zope/lib/python/ZPublisher/Publish.py, line 114, in publish File /var/zope/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: public) File /var/zope/lib/python/ZPublisher/Publish.py, line 98, in publish File /var/zope/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: index_html) File /var/zope/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: index_html) File /var/zope/lib/python/OFS/DTMLDocument.py, line 127, in __call__ (Object: index_html) File /var/zope/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: index_html) File /var/zope/lib/python/OFS/DTMLMethod.py, line 120, in __call__ (Object: list_robot) File /var/zope/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: list_robot) KeyError: (see above) It is Zope 2.5.1.
