Do we currently return NS_OK from Necko in such circumstances or another
error code?

Hey all,
In the networking team we're about to introduce an error code for
"partial transfers" (see
https://bugzilla.mozilla.org/show_bug.cgi?id=237623). It will be
returned when the underlying protocol's framing is cut off and we know
that the transfer was indeed partial - not all data arrived.
Right now the patch in progress returns this value for HTTP 1.1
Content-Length: underrun, cut off chunked-encoding chunks and broken
SPDY or http2 streams.
While the primary bug report for this identifies a problem in the
download manager that makes it not discover cut off transfers and
instead signal them as complete, this change will and can have some
further impact on other areas of Firefox and I want to highlight this,
give you all a heads up and listen in if there are any additional
thoughts or feedback on this pending change.
The question I think all consumers of protocol data need to ask
ourselves is: how should we deal with partial contents? Up until today,
we silently just ignored the potential problems and considered whatever
we got fine enough to use. Images? Javascript? CSS? Anything else?
This change will also make Firefox align with the other browsers that
already are stricter in this area.
