| Data structures and relations: |
| |
| BASIC VALUE TYPE: |
| |
| apreq_value_t: basic type for handling opaque data. The type |
| is meant to be extended by placing all "metadata" |
| in front (within a larger structure). |
| |
| COOKIES: |
| |
| apreq_cookie_t: extends apreq_value_t to represent server-side |
| cookie data. |
| |
| apreq_jar_t: This struct is analogous to apreq_request_t for params. |
| |
| PARAMS: |
| |
| apreq_param_t: extends apreq_value_t to represent POST param data. |
| |
| apreq_request_t: maintains arg/body tables which represent parsed data. |
| |
| REQUEST STATES: |
| req->body == NULL: No POST data has been read/parsed yet. The |
| req->parser slot may be safely modified. |
| |
| req->body != NULL: Some parsing has taken place, so req->parser |
| cannot be modified now without risking |
| loss of data. |
| |
| status: (as returned by apreq_env_read and APREQ_RUN_PARSER) |
| APR_INCOMPLETE: Parsing in progress. |
| APR_SUCCESS: Parsing complete. |
| <other>: parser error, parsing aborted. |
| |
| |
| PARSER EXTENSIONS: |
| |
| apreq_parser_t: parser callback, with its associated configuration data. |
| |
| apreq_hook_t: extends multipart/form-data parser by transforming incoming |
| brigades which represent the contents of a file upload. |
