Remove the HTTP_PARSER_DEBUG macro for two reasons:
* It changes the size of struct http_parser, resulting in spurious memory
corruption bugs if part of your application is built with HTTP_PARSER_DEBUG=1
and other parts with HTTP_PARSER_DEBUG=0.
* It's a debugging tool for maintainers. It should never have been exposed in
the API in the first place.
Makes it easier for integrators to generate bindings for the HTTP methods that
we support. Example:
// stringify method names
const char *methods[] = {
#define XX(num, name) #name,
HTTP_METHOD_MAP(XX)
#undef XX
};
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
- 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.
- 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.
