allow LIGHTTPD_EXE_PATH override to be able to run source tree tests/*.t
against installed executable, e.g. LIGHTTPD_EXE_PATH=/usr/sbin/lighttpd
Beware that tests might not pass or might not be supported if the target
executable is not the same version as that of the source tree
(Possible use for this override is by Debian autopkgtests)
disable server.graceful-restart-bg on OpenBSD and NetBSD
kqueue is not inherited across fork, and OpenBSD and NetBSD do not
implement rfork() (implemented on FreeBSD and DragonFly)
lighttpd has not implemented rebuilding the kqueues after fork,
so server.graceful-restart-bg is disabled on OpenBSD and NetBSD.
Note: there have always been limitations with lighttpd stat_cache.[ch]
using FAM/gamin on *BSD via kqueue() as lighttpd stat_cache.[ch] only
monitors directories. This kqueue() implementation also only monitors
directories and has limitations.
lighttpd stat_cache.[ch] is notified about additions and removals of
files within a monitored directory but might not be notified of changes
such as timestamps (touch), ownership, or even changes in contents
(e.g. if a file is edited through a hard link)
server.stat-cache-engine = "disable" should be used when files should
not be cached. Full stop. Similarly, "disable" is recommended if files
change frequently. If using server.stat-cache-engine with any engine,
there are caching effects and tradeoffs.
On *BSD and using kqueue() on directories, any change detected clears
the stat_cache of all entries in that directory, since monitoring only
the directory does not indicate which file was added or removed. This
is not efficient for directories containing frequently changed files.
include wolfssl/options.h crypto lib config
after selecting crypto lib to use
wolfSSL does not prefix its defines with a wolfSSL-specific namespace
(so we would like to avoid unnecessarily polluting preproc namespace)
This commit further isolates wolfSSL after split from mod_openssl.
Cleans up some preprocessor logic that was put in place when using
the wolfSSL compatibility layer for openssl, before creating a
workaround fragile code in wolfssl/wolfcrypto/types.h
Including header blows up compile in 32-bit when lighttpd meson build
in OpenWRT on a 32-bit platform generates lighttpd config.h containing
define of SIZEOF_LONG, but not SIZEOF_LONG_LONG, and the wolfssl types.h
flubs and fails to choose an enum value used by a macro that is unused
by most consumers of the wolfssl header.
(not (yet?) an end-user option in the build system)
(If extended to build system, build system should also unset CRYPTO_LIB)
If WITHOUT_LIB_CRYPTO is defined in sys-crypto.h, then non-TLS modules
will have access to MD5() and SHA1() built with lighttpd (algo_md5.[ch]
and algo_sha1.[ch]), but not to other message digest algorithms.
As of this commit, this affects only mod_secdownload with SHA256 digest
and mod_auth* modules using HTTP Digest Auth with digest=SHA-256, which
is not currently well-supported by client browers (besides Opera)
crippled functionality if wolfssl library not built --enable-opensslall
* SNI not handled since SNI callbacks are disabled in wolfSSL library
unless the wolfSSL library is built with --enable-openssall
This means that there is only one certificate per listening socket --
no certificate selection based on server name indication (SNI)
and is additionally a violation of the HTTP/2 specification,
which requires SNI.
slightly reduced functionality if wolfssl not built --enable-opensslall
* disable client certificate verification (error out if in lighttpd.conf)
* omit SSL_CIPHER_USEKEYSIZE, SSL_CIPHER_ALGKEYSIZE env vars
must update the cached copy of global scope config after cycling log.
Although (accesslog_st *) is modified in-place, the log_access_fd member
of (accesslog_st *) is copied into the cache and must be updated after
cycling logs in the global scope.
