- When handling upgraded bodies, http_parser_execute() used to return
one fewer bytes parsed than expected. This caused the final LF to be
interpreted by the caller as part of the body.
- Add a bunch of upgrade body unit tests.
Normal value cb is called for subsequent lines. LWS is skipped.
Note that \t whitespace character is now supported after header field name.
RFC 2616, Section 2.2
"HTTP/1.1 header field values can be folded onto multiple lines if the
continuation line begins with a space or horizontal tab. All linear
white space, including folding, has the same semantics as SP. A
recipient MAY replace any linear white space with a single SP before
interpreting the field value or forwarding the message downstream."
- Add IS_ALPHA(), IS_NUM(), IS_HOST_CHAR(), etc. macros for determining
membership in a character class. HTTP_PARSER_STRICT causes some of
these definitions to change.
- Support '_' character in hostnames in non-strict mode.
- Support leading digits in hostnames when the method is HTTP_CONNECT.
- Don't re-define HTTP_PARSER_STRICT in http_parser.h if it's already
defined.
- Tweak Makefile to run non-strict-mode unit tests. Rearrange non-strict
mode unit tests in test.c.
- Add test_fast to .gitignore.
Fixes#44
- This is non-spec behavior, but it appears that most HTTP servers
implicitly support non-ASCII characters when parsing path components.
Extend http-parser to allow this.
- Fill out slots [128, 256) in normal_url_char[] with 1 so that these
high octets are accepted in path components.
- Add unit test for paths that include such non-ASCII characters.
Fixes#37.
Check for overflow during chunk trailer by removing unnecessary check in macro PARSING_HEADER. This will force the parser to abort if the chunk trailer contains more than HTTP_MAX_HEADER_SIZE of data.
Without this change, it is possible to get an assertion to fail by
continuing to call http_parser_execute after it has returned an error.
Specifically, the parser could be called with parser->state ==
s_chunk_size_almost_done and parser->flags & F_CHUNKED set. Then,
F_CHUNKED could have been cleared, and an error could be hit. In this
case, the parser would have returned with F_CHUNKED clear, but
parser->state == s_chunk_size_almost_done, resulting in an assertion
failure on the next call.
There are alternate solutions possible, including just saving all of
the fields (state included) on error.
I didn't add a test case because this is a bit annoying to test, but I
can add one if necesssary.
acceptable_header[x] is always assigned to a variable of type char, so
the 'unsigned' is unnecessary.
The other arrays can be of type int8_t/uint8_t to save space.
