It doesn't need to be an instance function, and the new checks can cause some comparators to be called where they weren't before, causing debug assertions like the ones in bug 1947516 comment 13. Differential Revision: https://phabricator.services.mozilla.com/D243313

* FRAMECHECK_LAX - no check
|
|
* FRAMECHECK_BARELY - allows:
|
|
* 1) that chunk-encoding does not have the last 0-size
|
|
* chunk. So, if a chunked-encoded transfer ends on exactly
|
|
* a chunk boundary we consider that fine. This will allows
|
|
* us to accept buggy servers that do not send the last
|
|
* chunk. It will make us not detect a certain amount of
|
|
* cut-offs.
|
|
* 2) When receiving a gzipped response, we consider a
|
|
* gzip stream that doesn't end fine according to the gzip
|
|
* decompressing state machine to be a partial transfer.
|
|
* If a gzipped transfer ends fine according to the
|
|
* decompressor, we do not check for size unalignments.
|
|
* This allows to allow HTTP gzipped responses where the
|
|
* Content-Length is not the same as the actual contents.
|
|
* 3) When receiving HTTP that isn't
|
|
* content-encoded/compressed (like in case 2) and not
|
|
* chunked (like in case 1), perform the size comparison
|
|
* between Content-Length: and the actual size received
|
|
* and consider a mismatch to mean a
|
|
* NS_ERROR_NET_PARTIAL_TRANSFER error.
|
|
* FRAMECHECK_STRICT_CHUNKED - This is the same as FRAMECHECK_BARELY only we
|
|
* enforce that the last 0-size chunk is received
|
|
* in case 1).
|
|
* FRAMECHECK_STRICT - we also do not allow case 2) and 3) from
|
|
* FRAMECHECK_BARELY.
