* Introduce ap_scan_http_token / ap_scan_http_field_content for a muchWilliam A. Rowe Jr2016-07-291-51/+86
| | | | | | | | | | | | | | | | more efficient pass through the header text; rather than reparsing the strings over and over under the HTTP_CONFORMANCE_STRICT fules. Improve logic and legibility by eliminating multiple repetitive tests of the STRICT flag, and simply reorder 'classic' behavior first and this new parser second to simplify the diff. Because of the whitespace change (which I had wished to dodge), reading this --ignore-all-space is a whole lot easier. Particularly against 2.4.x branch, which is now identical in the 'classic' logic flow. Both of which I'll share with dev@ git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1754556 13f79535-47bb-0310-9956-ffa450edef68

* core: Limit to ten the number of tolerated empty lines between request,Yann Ylavic2015-10-221-7/+12
| | | | | | | | | | | | | | | | | | | | | | | and consume them before the pipelining check to avoid possible response delay when reading the next request without flushing. Before this commit, the maximum number of empty lines was the same as configured LimitRequestFields, defaulting to 100, which was way too much. We now use a fixed/hard limit of 10 (DEFAULT_LIMIT_BLANK_LINES). check_pipeline() is changed to check for (up to the limit) and comsume the trailing [CR]LFs so that they won't be interpreted as pipelined requests, otherwise we would block on the next read without flushing data, and hence possibly delay pending response(s) until the next/real request comes in or the keepalive timeout expires. Finally, when the maximum number of empty line is reached in read_request_line(), or that request line does not contains at least a method and an (valid) URI, we can fail early and avoid some failure detected in further processing. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1710095 13f79535-47bb-0310-9956-ffa450edef68
