It's useful to check if the current chunk is the last one.
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.
Thanks to Steve Ridout for the patch. Fixes #69.
…ere errno is defined as a macro
- 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.
- 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.
