OpenResty 1.21.4.2 Released
Johnny Wang , 19 Jul 2023 (created 19 Jul 2023)We are happy to announce the new formal release, 1.21.4.2, of the OpenResty web platform based on NGINX and LuaJIT.
The (portable) source code distribution, the Win32/Win64 binary distributions, and the pre-built binary Linux packages for Ubuntu, Debian, Fedora, CentOS, RHEL, Alpine, OpenSUSE, Amazon Linux, Rocky Linux, Oracle Linux, and CBL Mariner are provided on this Download page.
Version Highlights
- LuaJIT
- Avoid negation of signed integers in C that may hold INT*_MIN, since recent C compilers 'take advantage' of the undefined behavior, this completely changes the meaning of expressions like
(k == -k)
. - Correct fix for stack check when recording
BC_VARG
. - Fix trace join to
BC_JLOOP
originating fromBC_ITERN
. - Fix
math.floor()
andmath.ceil()
. - Many fixes imported from Mike Pall's upstream https://github.com/luajit/luajit repository.

- Fixed a bug that uses memory after free when encountering an invalid
IF-Match
request header. Thanks to Michal Jeczalik Jr, Nishant Hooda and Kong Inc for reporting this issue. - Implemented
monotonic_msec()

- Reimplemented
tcpsock:sslhandshake
, coroutine wrapper, andngx.req.is_internal
with FFI. - SSL/TLS supports passphrase protected private key.
- Fixed a segmentation fault when get headers via
ngx.req.raw_header
with malformed requests. - Fixed potential null pointer dereference.
- lua-cjson module
empty_array
can not work on Apple because cjson did not compare light userdata address with masked address. Since we usedjson_lightudata_mask
when creating lightuserdata, same mask should be applied when comparing the return oftouserdata
.
- headers-more-nginx-module module
- Fixed crash while accessing uninitialized pointer.
- lua-resty-websocket module
