Special thanks go to all our developers and contributors!
The highlights of this release are:
1. New real-time in-memory nginx error log capturing API. Now it's
easy to inspect nginx error logs on the Lua land without accessing any
files.
2. Ability to launch a privileged agent process under the master,
which runs under the same system account as master. This process does
not handle any incoming traffic, but can do system operations work and
nginx master management via signals. This does not work on Win32
though.
3. Now the Lua light threads can voluntarily yield the execution
control to the nginx event loop without introducing any extra delays
(previously it requires an extra delay of at least 1 millisecond).
This is achieved by the ngx.sleep(0) call on the Lua land.
4. New ngx.timer.every() Lua API for easily creating recurring timers
on the Lua land.
5. New Lua API function for tuning the JIT stack size of PCRE.
6. New Lua API for fetching the current nginx error_log filtering
level in efffect.
7. Now we search for LuaJIT bytecode files *.ljbc in the default
search paths before searching *.lua files.
8. Enforces nginx to do graceful shutdown even in single process mode
(i.e., master is off). This does not work on Win32 though.
Complete change logs since the last (formal) release, 1.11.2.4:
* feature: applied a patch to the nginx core to make the nginx
variable $proxy_add_x_forwarded_for accessible on Lua land.
thanks spacewander for the patch.
* feature: added the balancer-status-code patch to the nginx core
to allow returning arbitrary HTTP status codes inside upstream
balancers. thanks Datong Sun for the patch.
* feature: we now search LuaJIT bytecode files "*.ljbc" before Lua
source files "*.lua" in the default Lua module search paths.
* feature: applied the intercept-error-log patch to the nginx core
to provide 3rd-party modules a hook to intercept nginx error log
data without touching files. 3rd-party modules can register a
custom interception hook to
"ngx_http_core_main_conf_t.intercept_log_handler". thanks
Yuansheng Wang for the patch.
* feature: "./configure": the user flags specified by the
"--with-luajit-xcflags=FLAGS" option are not appended to the
default flags instead of being prepended. thanks spacewander for
the report.
* feature: applied a small patch to the nginx core to add support
for the "privileged agent" process which is run by the same
system account as the master. thanks Yuansheng Wang for the
patch.
* change: applied a patch to the nginx core to turn nginx to
openresty in the builtin special response pages' footer. thanks
Datong Sun for the patch.
* bugfix: the feature test for SSE 4.2 support did not really
check if the local CPU indeed has it. thanks Jukka Raimovaara
for the patch.
* bugfix: applied the single-process-graceful-exit patch to the
nginx core to fix the issue that nginx fails to perform graceful
exit when "master_process" is turned off.
* bugfix: "./configure": the "--without-http_lua_upstream" option
alone incorrectly disabled all the Lua stuff.
* feature: applied the delayed-posted-events patch to the nginx
core for adding "delayed posted events" which run in the next
event cycle with 0 delay. this nginx core feature is needed by
the "ngx.sleep(0)" feature in ngx_lua, for example. thanks
Datong Sun for the patch.
* change: swtched to OpenResty's own fork of "ngx_postgres":
https://github.com/openresty/ngx_postgres
* doc: updated the LuaJIT restydoc indexes to the latest version.
* upgraded resty-cli to 0.19.
* feature: resty: added new command-line option
"--errlog-level LEVEL". thanks Michal Cichra for the patch.
* feature: resty: added new command-line option "--rr" to use
"rr record" to run the underlying C process. this is for
Mozilla rr recording.
* feature: resty: added new command-line option "--gdb" to use
gdb to run the underlying C process.
* feature: resty: implemented the "--http-conf CONF"
command-line option.
* feature: added the "--ns IP" command line options to
override system (or google) nameservers. thanks Aapo
Talvensaari for the patch.
* bugfix: we did not quote the Lua code chunk names properly.
* bugfix: bad Lua file names given on the command line might
give rise to strange errors and even hanging.
* bugfix: resty: user created timers and unwaited light
threads were not handled gracefully upon exit.
* bugfix: md2pod.pl: we did not unescape "*".
* optimize: resty: now we increase the value of
lua_regex_cache_max_entries to 40K.
* doc: made it clear that one should install "openresty-resty"
and/or "openresty-doc" if they uses the offiical OpenResty
pre-built Linux package repositories.
* upgraded ngx_lua to 0.10.10.
* feature: added pure C API for tuning the "jit_stack_size"
option in PCRE. this is used by the ngx.re library of
lua-resty-core.
* feature: added pure C functions
"ngx_http_lua_ffi_worker_type()" &
"ngx_http_lua_ffi_worker_privileged()" for the ngx.process
module in lua-resty-core.
* feature: added new config directive lua_intercept_error_log
for capturing nginx error logs on Lua land. the
corresponding Lua API is provided by the ngx.errlog module
in lua-resty-core. thanks Yuansheng Wang for the patch and
Jan Prachař for a bug fix.
* feature: implemented the ngx.timer.every() API function for
creating recurring timers. thanks Dejiang Zhu for the patch.
* feature: balancer_by_lua*: now the user Lua code can
terminate the current request with arbitrary HTTP response
status codes via ngx.exit().
* feature: added pure C API function
"ngx_http_lua_ffi_errlog_get_sys_filter_level" for the
"ngx.errlog" module's "get_sys_filter_level()" function in
the lua-resty-core library. thanks spacewander for the
patch.
* feature: "ngx.sleep(0)" now always yield the control to the
nginx event loop. this can be used to do voluntary CPU time
slicing when running CPU intensive computations on the Lua
land and to avoid such computations from blocking the nginx
event loop for too long. this feature requires OpenResty's
delayed-posted-event patch for the nginx core.
* feature: added new pure C API
"ngx_http_lua_ffi_process_signal_graceful_exit()" for the
signal_graceful_exit() function of the ngx.process module in
lua-resty-core.
* feature: nginx 1.11.11+ can now build with this module.
note: nginx 1.11.11+ are still not an officially supported
target yet.
* bugfix: the running timer counter might go out of sync when
non-timer handlers using fake requests are involved (like
ssl_certficate_by_lua* and ssl_session_fetch_by_lua*).
thanks guanglinlv for the patch.
* bugfix: ngx.encode_args() did not escape "|", ",", "$", "@",
and """. now it is now consistent with what Google Chrome's
JavaScript API function "encodeURIComponent()` does. thanks
goecho for the patch.
* bugfix: ngx.escape_uri() did not escape "|", ",", "$", "@",
and "`".
* bugfix: segmentation fault would occur when several server
{} blocks listen on the same port or unix domain socket file
path *and* some of them are using ssl_certificate_by_lua*
configurations while some are not. thanks petrovich-ua for
the report and original patch.
* bugfix: the fake requests/connections might leak when memory
allocations fail. thanks skyever for the patch.
* bugfix: segmentation fault might happen when a stale read
event happens after the downstream cosocket object is
closed. thanks Dejiang Zhu for the report.
* bugfix: ngx.semaphore: when nginx workers exit, the harmless
error message "semaphore gc wait queue is not empty" might
be logged.
* bugfix: fixed typos in error messages. thanks spacewander
for the patch.
* refactor: ocsp: removed a useless line of code, which
unbreak the libressl build. thanks Kyra Zimmer for the
original patch.
* doc: fixed a typo in a code example for "ngx.re.match".
thanks Ming Wen for the patch.
* upgraded lua-resty-core to 0.1.12.
* feature: added opt() function to the ngx.re Lua module that
accepts the "jit_stack_size" option to tune the JIT stack
size of PCRE. thanks Andreas Lubbe for the patch.
* feature: added new Lua module ngx.process which has
functions type() and enable_privileged_agent(). thanks
Yuansheng Wang for the patch.
* feature: added new Lua module ngx.errlog which provides Lua
API to capture nginx error log data on Lua land.
* feature: added the new signal_graceful_exit() function to
the ngx.process Lua module.
* feature: ngx.errlog: added the get_sys_filter_level() API
function to get the "system" error log filtering level
defined in nginx.conf's error_log directive. thanks
spacewander for the patch.
* bugfix: ngx.re: split() might enter infinite loops when the
regex yields matches with empty captures.
* optimize: simplified the "BOOL and true or false"
expressions. thanks Evgeny S for the patch.
* doc: ngx.ssl: added performace notes for set_priv_key() and
set_cert(). thanks Filip Slavik for the patch.
* doc: ngx.balancer: fixed some typos. thanks detailyang for
the patch.
* doc: code example: private keys are usually stored in PEM,
so we use the func priv_key_pem_to_der in the example to do
the conversion.
* doc: ngx.ssl.session: fixed the missing arguments in the
code example. thanks soul11201 for the patch.
* doc: fixed the code examples since directives
"ssl_session_*_by_lua*" are no longer allowed in "server
{}". thanks Yuansheng Wang for the patch.

for the human readable "info" message in MySQL's "OK
packet". thanks zhuanyenan for the report.
* upgraded lua-resty-lock to 0.07.
* feature: added new method expire() that can change the TTL
of the lock being held.
* upgraded lua-resty-string to 0.10.
* bugfix: resty.aes: fixed memory overrun bug when user
provided a salt of less than 8 characters but

* refactor: commented out unneeded locals, and removed unused
variable declarations. thanks Aapo Talvensaari for the
patch.
* doc: typo fixes from Juarez Bochi.
* upgraded lua-resty-upstream-healthcheck to 0.05.

the patch.
* doc: typo fixes from Mike Rostermund.
* upgraded lua-resty-limit-traffic to 0.04.
* bugfix: reduce race condition between get/incr(key). by
using "incr" first, we could avoid overcommits between
"get(key)" and "incr(key)". thanks spacewander for the
patch.
* upgraded lua-resty-lrucache to 0.07.
* bugfix: fixed a type mismatch issue found by 其实不想走. the old
form still works due to LuaJIT FFI's magic.

https://github.com/openresty/luajit2/tags
* bugfix: FFI C parsers could not parse some C constructs like
"__attribute((aligned(N)))" and "#pragma". decoupled hash
functions used in comparison (hardcoded) and string table.
