Glenn Strauss 122094e3e3 [multiple] employ http_date.h, sys-time.h
- replace use of strptime() w/ implementation specialized for HTTP dates
- use thread-safe gmtime_r(), localtime_r() (replace localtime, gmtime)

Glenn Strauss 7c7f8c467c [multiple] split con, request (very large change)
NB: r->tmp_buf == srv->tmp_buf (pointer is copied for quicker access)

NB: request read and write chunkqueues currently point to connection
    chunkqueues; per-request and per-connection chunkqueues are
    not distinct from one another
      con->read_queue  == r->read_queue
      con->write_queue == r->write_queue

NB: in the future, a separate connection config may be needed for
    connection-level module hooks.  Similarly, might need to have
    per-request chunkqueues separate from per-connection chunkqueues.
    Should probably also have a request_reset() which is distinct from

Glenn Strauss f24e6d696a [multiple] plugin_stats array
use global rather than passing around (server *) just for that

Glenn Strauss 80638252dc [multiple] validate UTF-8 in url-decoded paths
validate UTF-8 in url-decoded paths obtained elsewhere than from request

(burl_normalize(), if enabled with server.http-parseopts, checks url for
 overlong encodings of ASCII chars in the HTTP request-line)
2018-11-25 19:52:08 -05:00
Glenn Strauss e8e59396d3 [core] reject decoded url-path without leading '/'
buffer_simplify_path() no longer prepends '/' if '/' is missing.
Callers must check for leading '/' depending on use, such as in
concatenation with others paths, or direct use accessing filesystem

Note: lighttpd 1.4.50 provides the server.http-parseopts directive.
Recommended settings unless specific use requires looser settings:
  server.http-parseopts = (
    "header-strict"            => "enable",
    "host-strict"              => "enable",
    "host-normalize"           => "enable",
    "url-normalize"            => "enable",
    "url-normalize-unreserved" => "enable",
    "url-normalize-required"   => "enable",
    "url-ctrls-reject"         => "enable",
    "url-path-2f-decode"       => "enable",
    "url-path-dotseg-remove"   => "enable",
    "url-query-20-plus"        => "enable"


As noted in the link above, mod_access should be preferred instead
of mod_rewrite for access controls to URLs.

buffer_is_equal_caseless_string() now correctly matches against
