[zope2-tracker] [Bug 403083] [NEW] Wrong check for Transfer-Encoding "chunked" in Zope while using finder (MacOS) as webdav client

[Sven Rudolph]

Public bug reported:

According to RFC2616 - Hypertext Transfer Protocol -- HTTP/1.1, Chapter
3.6 all transfer-coding values are case-insensitive, but Zope checks for
"chunked" only as lower case string.

Found in (Zope-2.11.3):
zope/server/http/httprequestparser.py. line 147
zope/server/http/httptask.py, line 138
ZServer/medusa/http_server.py, line 216

Result:
Uploaded files with finder (MacOSX) as webdav client always have a length of 0 Bytes.
Finder sends the transfer-coding value as "Chunked" (with a capital C), which is allowed according to RFC2616, but falls through the checks in the listed files.


Greetings
Sven
