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).
- Uses more standard $CFLAGS and $CPPFLAGS variables to populate the set
of flags to build with.
- Allow extending compilation and linking flags with
$CPPFLAGS_DEBUG_EXTRA, $CPPFLAGS_FAST_EXTRA, $CFLAGS_DEBUG_EXTRA, and
$CFLAGS_FAST_EXTRA.
Closes#40.
- Add http_errno enum w/ values for many parsing error conditions. Stash
this in http_parser.state if the 0x80 bit is set.
- Report line numbers on error generation if the (new) HTTP_PARSER_DEBUG
cpp symbol is set. Increases http_parser struct size by 8 bytes in
this case.
- Add http_errno_*() methods to help turning errno values into
human-readable messages.
- 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.
