problem opening pdf-files with firefox in LocalFS folders on Zope
Hi, I've got Zope 2.8.5 installed with LocalFS version LocalFS-1-3-andreas on Solaris (SunOs 5.8, I'm not sure which version number of solaris that is...) When I place pdf-files in the LocalFS directories, sometimes they open correctly, but most of the time they open as text-file when using Firefox. With other browsers (Internet Explorer, Opera) this problem does not occur. In the directory-listing the files are all identified correctly as type "application/pdf". At first I thought that Firefox had problems with some documentversions of pdf, so instead of using version 1.6 I tried 1.2. But no luck. When placing the files in the zope db, and not in a LocalFS folder, Firefox has no problems with any of them, and just opens them fine. Does anyone have a clue what is going wrong here and even better, how I can solve this problem? Thanks in advance, Ria Marinussen

A bug in "LocalFS". In our local copy, I fixed it this way (in "LocalFS/StreamingFile.py"): class StreamingFile(File): .... # DM 2005-11-07 # funny that we should not need a "Content-Type" header # when the file is sufficiently small? if RESPONSE is not None: # DM 2005-11-18: support for 'if_modified_since' and range requests if self._if_modified_since_request_handler(REQUEST, RESPONSE): # we were able to handle this by returning a 304 return '' if self._range_request_handler(REQUEST, RESPONSE): # we served a chunk of content in response to a range request. return '' RESPONSE.setHeader('Content-Type', self.content_type) #DM 2005-11-17: 'Last-Modified' support RESPONSE.setHeader( 'Last-Modified', rfc1123_date(stat(self._local_path)[8]) ) # DM 2005-11-18: support for range requests RESPONSE.setHeader('Accept-Ranges', 'bytes') threshold = 2 << 16 # 128 kb if self.size < threshold or RESPONSE is None: try: f = open(self._local_path, 'rb') return f.read() finally: f.close() else: RESPONSE.setHeader('Content-Length', self.size) # DM 2005-11-07: moved outside the "if" #RESPONSE.setHeader('Content-Type', self.content_type) return filestream_iterator(self._local_path, 'rb') The fix also provides "if-modified-since" and "if-ranges".
With other browsers (Internet Explorer, Opera) this problem does not occur.
They ignore the (wrong) "Content-Type" and look on the filename extension. -- Dieter
