the v6 parsing works by adding extra states for working with the
[] notation for v6 addresses. hosts and ports cannot be 0-length
because we url parsing from ending when we expect those fields to
begin.
http_parser_parse_url gets a free check for the correctness of
CONNECT urls (they can only be host:port).
this addresses the following issues:
i was bored and had my head in this space.
Before this change it would include the last slash in the separator between the
schema and host as part of the host. we cant use the trick used for skipping the
separator before ports, query strings, and fragments because if it was a CONNECT
style url string (host:port) it would skip the first character of the hostname.
Work around this by introducing a few more states to represent these separators
in a url differently to what theyre separating. this in turn lets us simplify
the url parsing so can simply skip what it considers delimiters rather than
having to special case certain types of url parts and skip their prefixes.
Add tests for the http_parser_parse_url().
This compares the http_parser_url struct that http_parser_parse_url()
produces against one that we expect from the test. If they differ
then http_parser_parse_url() misbehaved.
'inline' is not a recognized C89 keyword, it made the build fail with strict or
older compilers (msvc 2008, gcc with -std=c89).
'inline' is also just a hint, one that gcc 4.4.3 in this particular case happily
ignored. Ergo, remove it.
Summary:
- Add http_parser_pause() API. A callback may invoke this at any time.
This will cause http_parser_parse() to return indicating that it
parsed less than the number of requested bytes and set an error to
HBE_PAUSED. A paused parser with fail with HBE_PAUSED until it is
un-paused with http_parser_pause().
- Stop using 'state', 'header_state', 'index', and 'nread' shadow
variables and then updating their http_parser fields when we're done.
Instead, update the live values as we go. This will make it possible
to return from anywhere in the parser (say, due to EPAUSED) and have
valid/expected state.
- Update state before making callbacks so that if the want to pause,
we'll know the correct state already.
- Make sure that every callback has a state that uniquely identifies the
next step so that we can resume in the right place if we were suppoed
to be paused.
- Clean and re-factor up CALLBACK() macros.
- Use CALLBACK() macros for (almost) all callbacks; on_headers_complete
is still a special case. This includes on_body which we used to invoke
manually with a long run of bytes. We now use a 'body' mark and hit
its callback just like every other data callback.
- Clean up (most) gotos and replace with real states.
- Add some unit tests.
Fixes#70
- Break EOF handling out of http_should_keep_alive() into
http_message_needs_eof(), which we now use when determining what to do
with a message of unknown length. This prevents us from falling into
the s_body_identity_eof state in the cases where we actually *do* know
the length of the message (e.g. because the response status was 204).
- Add an http_parser_parse_url() method to parse a URL into its
constituent components. This uses the same underlying parser
as http_parser_parse() and doesn't do any data copies.
- Re-add the URL components in various test.c structures; validate
them when parsing.
- Treat ' ' specially, as apparently IIS6.0 can send this in headers.
Allow this character through if we're not in strict mode.
- Move some test code around so that test indices don't break when
HTTP_PARSER_STRICT changes.
Fixes#13.
With HTTP/1.1, if neither Content-Length nor Transfer-Encoding is present,
section 4.4 of RFC 2616 suggests http-parser needs to read a response body
until the connection is closed (except the response must not include a body)
See also joyent/node#2457.
Fixes#72
- Get rid of support for these callbacks in http_parser_settings.
- Retain state transitions between different URL portions in
http_parser_execute() so that we're making the same correctness
guarantees as before.
- These are being removed because making multiple callbacks for the same
byte makes it more difficult to pause the parser.
- This was only used by CALLBACK() (which then cleared the mark anyway),
and the end of the http_parser_execute() body (after which they
go out of scope).
