Are there major known issues with CFHTTPStream? I'm encountering
situations
where it returns a -1 (parse failure) error in the HTTP error domain.
I don't know of any known issues here; in particular, the only cases
I've seen where a parse failure is returned have been legitimate server
errors (the server returned data that was not a valid HTTP response,
and could not be parsed as such).
I've seen two situations (one that seems to point to issues with HTTP
1.1
and chunked transfer-encoding, and the other seems to be somewhat less
concrete: timing related issues that may point to how it deals with
buffering of incoming data).
I've seen examples where the server omits the final CRLF from the final
chunk, and causes a parse error to be returned up the stream; this is a
valid parse failure (the HTTP transaction is not complete until that
final CRLF comes in), but is of little use since the client can't tell
whether the error occurred on the final chunk or an earlier one. If
this is what you're running in to, the workaround is to assume the data
you've received is valid and see if it contains all the content you're
expecting.
Before I spend a lot of time developing workarounds or generating test
cases
for bug reports (and maybe ultimately writing a new HTTP backend for
our
code...) are there known issues with this code?
I've posted the exhaustive list of known issues (to the best of my
knowledge) on this list before; if you search the archives, you should
find it pretty quickly. That might be a good place to start. However,
from your description, I suspect either a faulty HTTP server or a
faulty proxy en route to the server. I vote for the test cases for bug
reports. :)
