define LSHPACK_DEC_HTTP1X_OUTPUT 0
lighttpd does not require HTTP/1.1 output compat from HPACK decoder
("field-name: value\r\n")
define NDEBUG (in ls-hpack/lshpack.c)
lighttpd spends upwards of 20% total lighttpd CPU time in HPACK
encode/decode in h2load test on static file over cleartext (not TLS)
Defining NDEBUG eliminates some asserts() and results in a small
but measurable reduction in CPU usage
LiteSpeed ls-hpack v2.2.1
XXX: might be better to include this as a git submodule
but minor code changes were made here for portability:
- C99 flexible array members defined as a[] instead of a[0])
- pedantic compiler warnings (excess ';' and missing declarations)
- deletion of large tables from ls-hpack/huff-tables.h (code size)
(subsequently incrementally updated using git rebase)
huge props and many thank yous to writers of testing tools used while
developing HTTP/2 support in lighttpd:
h2spec - conformance testing tool for HTTP/2 implementation
https://github.com/summerwind/h2spec
h2load - HTTP/2 benchmarking tool
https://nghttp2.org/documentation/h2load-howto.html
curl - command line tool and library for transferring data with URLs

./configure --with-nettle to use Nettle crypto lib for algorithms,
instead of OpenSSL or wolfSSL. Note: Nettle does not provide TLS.

even 2 billion is way larger than even extreme operating values
expected for the members in base.h
include some structs directly in struct server, rather than by ptr
sys/event.h does not compile standalone, so check_include_files() fails
Add compiler flags -include sys/types.h so that the compile check passes
This allows cmake builds on FreeBSD to detect and use kqueue.
(missing HAVE_WOLFSSL_SSL_H without add_definition() suggests that
there are other definitions that are not being exported for use
in the build, so lighttpd built with CMake has base features only)
server.http-parseopts = ( ... ) URL normalization options
Note: *not applied* to CONNECT method
Note: In a future release, URL normalization likely enabled by default
(normalize URL, reject control chars, remove . and .. path segments)
To prepare for this change, lighttpd.conf configurations should
explicitly select desired behavior by enabling or disabling:
server.http-parseopts = ( "url-normalize" => "enable", ... )
server.http-parseopts = ( "url-normalize" => "disable" )
x-ref:
"lighttpd ... compares URIs to patterns in the (1) url.redirect and (2) url.rewrite configuration settings before performing URL decoding, which might allow remote attackers to bypass intended access restrictions, and obtain sensitive information or possibly modify data."

unit tests for request processing
collect existing request processing tests from Perl tests/*.t
(test_request.c runs *much* more quickly than Perl tests/*.t)
