Re: [Zope] ExtFile Extention Mappings

[Stefan H. Holek]

Why?
Because one of the main tricks of ExtFile is the ability to have files 
and images served statically by Apache, right out of the repository. 
Apache determines the mime type to serve from the file extension, ergo 
ExtFile has to make sure there is one.

How?
from mimetypes import guess_extension
ext = guess_extension(self.content_type)
If this yields the wrong result perhaps your system's mimetypes table 
is messed up? I must admit my use case is images for the most part, and 
they work just fine.

If this does not do what you want poke around a bit in Config.py. You 
can change almost every aspect of ExtFile's repository handling.

Re: [Zope] ExtFile Extention Mappings

[Satchidanand Haridas]

Hi,
Have you had a look at the Config.py file? I believe you can change the 
settings there so that the Zope filenames are preserved including the 
extensions. More specifically, I am referring to the following section 
in Config.py:

section
# repository file extension handling
ZOPEID = 0  # use ZOPEID (even if it doesn't include an 
extension)
MIMETYPE_APPEND = 1 # append extension to ZOPEID according to mimetype
MIMETYPE_REPLACE = 2# remove extension from ZOPEID, then append mime 
extension

REPOSITORY_EXTENSIONS = MIMETYPE_REPLACE
/section
Thanks.

In our quest to replace the not-quite-working External File product, 
we're looking at ExtFile. However, when I upload files into an 
ExtFile, file extensions on the file system are being changed. 
test1.txt becomes test1.ksh, test2.doc becomes test2.dot. They have 
the correct ID's in the ZMI, but on the file system they now have 
something quite new.

Our solution relies on accessing via the ZMI and the file system at 
the same time, so the name being changed is somewhat inconvenient in 
its unpredictability (and I think Apaches mime types will get nicely 
screwed if we start bypassing Zope to get at them). I've done some 
poking at the source code but don't see why ExtFile is doing this or 
what logic it uses.

I bet someone out there knows.
