lib-http: If istream read fails, preserve the istream's full error message

global: start relying on pool_unref(NULL) being a no-op Cleanup performed with the following semantic patch: @@ expression E; @@ - if (E != NULL) { - pool_unref(&E); - } + pool_unref(&E);

lib-http: message parser: Reject messages with invalid Date header when HTTP_MESSAGE_PARSE_FLAG_STRICT flag is enabled.

lib-http: message parser: Allow duplicate date header if HTTP_MESSAGE_PARSE_FLAG_STRICT is not set. The last instance of the date header is used.

lib-http: Restructured the header, message, request, and response parsers to have an extensible and consistent API using flags. Extended the test suites with a few cases that test parsing with and without the STRICT flag.

lib-http: message parser: Don't allocate a pool for the next message until it is needed. This prevents wasting memory when no message is being parsed.

lib-http: message parser: Delay allocation of message header.

lib-http: message parser: Don't create the connection_options array, unless it is actually used.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

lib-http: message parser: Made sure that payload stream is always destroyed (hence closed) when the next request is to be parsed. This makes sure that the connection input is always at the correct position for the next request. Remaining references to the payload stream could theoretically mess this up.

lib-http: ref/unref input stream in http message parser To prevent assidental disappearance of the stream while it's in use. Also, the caller can create and forget - we'll do the cleanup later. Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib-http: Minor improvement to "disconnected during payload read" error message. The same error is also used for http-server for parsing client input, so the message shouldn't say anything about reading the input from server.

lib-http: Don't silently truncate response payload if server disconnects during it.

lib-http: Updated comments to RFC7230/RFC7231.

Updated copyright notices to include year 2014.

lib-http: Added option to the header parser to make it lenient towards illegal characters in header field content. The offending characters are then skipped without error. This is required for the http client as a workaround for bugs in certain HTTP servers. This behavior is explicitly not enabled for the http-request-parser as used by our own HTTP server implementation.

lib-http: Added support for handling HTTP/1.0 messages explicitly. This means that default connection persistence semantics are inverted for HTTP/1.0 and keep-alive Connection option is recognized.

lib-http: Added support for enforcing a payload limit for incoming HTTP messages.

lib-http: Adjusted message and request parsers to return an error code.

lib-http: Implemented limits on overall HTTP header size, size of individual header fields and the number of fields in the header.

lib-http: Unified http-request.h and http-response.h headers. Renamed struct http_response_header to struct http_header_field, encapsulated the array in struct http_header and put it all in http-header.h/c Added inline utility functions for header querying and getting response/request payload size.

lib-http: Improved message header and body parsing for better RFC compliance. Added pre-parsed transfer-encoding and connection header content (array) to parsed message struct. Fixed message body handling for when both transfer-encoding and content-length headers are missing. Now duplicates of unique important message headers yield an error.

lib-http: Adjusted message parser to accept pool from caller.

lib-http: Implemented http-request-parser for HTTP servers. Moved code common with it and http-response-parser to http-message-parser.
