Version 1.7.7.2 - 4 February 2015

  • bundled the "resty" command-line utility (version 0.01) from the resty-cli project: https://github.com/openresty/resty-cli
    • bugfix: the resty utility could not start when the nginx was built with ./configure --conf-path=PATH where PATH was not conf/nginx.conf. thanks Zhengyi Lai for the report.
    • feature: added support for user-supplied arguments which the user Lua scripts can access via the global Lua table "arg", just as in the "lua" and "luajit" command-line utilities. thanks Guanlan Dai for the patch.
    • feature: added new command-line option --nginx=PATH to allow the user to explicitly specify the underlying nginx executable being invoked by this script. thanks Guanlan Dai for the patch.
    • feature: added support for multiple -I options to specify more than one user library search paths. thanks Guanlan Dai for the patch.
    • feature: print out resty's own version number when the -V option is specified.
    • feature: resty: added new options --valgrind and --valgrind-opts=OPTS.
  • upgraded Set Misc Nginx Module to 0.28.
  • upgraded Lua Nginx Module to 0.9.14.
    • bugfix: ngx.re.gsub/ngx.re.sub incorrectly swallowed the character right after a 0-width match that happens to be the last match. thanks Guanlan Dai for the patch.
    • bugfix: tcpsock:setkeepalive(): we did not check NULL connection pointers properly, which might lead to segmentation faults. thanks Yang Yue for the report.
    • bugfix: ngx.quote_str_str() incorrectly escaped "\026" to "\z" while "\Z" is expected. thanks laodouya for the original patch.
    • bugfix: ngx.timer.at: fixed a small memory leak in case of running out of memory (which should be extremely rare though).
    • optimize: minor optimizations in timers.
    • feature: added the Lua global variable __ngx_cycle which is a lightuserdata holding the current ngx_cycle_t pointer, which may simplify some FFI-based Lua extensions.
    • doc: added a warning for the "share_all_vars" option for ngx.location.capture*.
  • upgraded Lua Resty Core Library to 0.1.0.
    • bugfix: resty.core.regex: data corruptions might happen when recursively calling ngx.re.gsub via the user replacement function argument because of incorrect reusing a globally shared captures Lua table. thanks James Hurst for the report.
    • bugfix: ngx.re.gsub: garbage might get injected into gsub result when ngx.* API functions are called inside the user callback function for the replacement. thanks James Hurst for the report.
    • feature: resty.core.base: added the FFI_BUSY constant for NGX_BUSY.
  • upgraded Lua Resty Lrucache Library to 0.04.
    • bugfix: resty.lrucache.pureffi: set(): it did not update to the new value at all if the key had an existing value (either stale or not). thanks Shuxin Yang for the patch.
  • upgraded Lua Resty Web Socket Library to 0.05.
    • feature: resty.websocket.client: added support for SSL/TLS connections (i.e., the wss:// scheme). thanks Vladislav Manchev for the patch.
    • doc: mentioned the bitop library dependency when using the standard Lua 5.1 interpreter (this is not needed for LuaJIT because it is already built in). thanks Laurent Arnoud for the patch.
  • upgraded LuaJIT to v2.1-20150120: https://github.com/openresty/luajit2/tags
    • imported Mike Pall's latest changes:
      • bugfix: don't compile IR_RETF after CALLT to ff with side effects.
      • bugfix: fix BC_UCLO/BC_JMP join optimization in Lua parser.
      • bugfix: fix corner case in string to number conversion.
      • bugfix: x86: fix argument checks for ipairs() iterator.
      • bugfix: gracefully handle lua_error() for a suspended coroutine.
      • x86/x64: Drop internal x87 math functions. Use libm functions.
      • x86/x64: Call external symbols directly from interpreter code. (except for ELF/x86 PIC, where it's easier to use wrappers.)
      • ARM: Minor interpreter optimization.
      • x86: Minor interpreter optimization.
      • PPC/e500: Drop support for this architecture.
      • MIPS: Fix excess stack growth in interpreter.
      • PPC: Fix excess stack growth in interpreter.
      • ARM: Fix excess stack growth in interpreter.
      • ARM: Fix write barrier check in BC_USETS.
      • ARM64: Add build infrastructure and initial port of interpreter.
      • OpenBSD/x86: Better executable memory allocation for W^X mode.
  • bugfix: the ngx_http_redis module failed to compile when the ngx_gzip module was disabled. thanks anod221 for the report.

Version 1.7.7.1 - 6 December 2014

  • upgraded the Nginx core to 1.7.7.
  • bugfix: applied a patch to the nginx core to fix the memory invalid reads when exceeding the pre-configured limits in an ngx_hash_t hash table.
  • bugfix: applied a patch to the nginx core to fix a memory invalid read regression introduced in nginx 1.7.5+'s resolver.
  • ./configure: usage text: renamed --with-luajit=PATH to --with-luajit=DIR. thanks Dominic for the suggestion.
  • feature: ./configure: added the default prefix value to the usage text.
  • upgraded LuaJIT to v2.1-20141128: https://github.com/openresty/luajit2/tags
    • imported Mike Pall's latest changes:
      • feature: FFI: added ffi.typeinfo(). thanks to Peter Colberg.
      • bugfix: fixed snapshot #0 handling for traces with a stack check on entry. this bug might lead to bad register overwrites (and eventually segmentation faults in GC upon trace exits, at least).
      • bugfix: FFI: no meta fallback when indexing pointer to incomplete struct.
      • bugfix: fixed fused constant loads under high register pressure.
      • bugfix: fixed DragonFly build (unsupported). thanks to Robin Hahling, Alex Hornung, and Joris Giovannangeli.
      • bugfix: FFI: fixed initialization of unions of subtypes. thanks to Peter Colberg.
      • bugfix: FFI: Fix for cdata vs. non-cdata arithmetic and comparisons. thanks to Roman Tsisyk.
      • optimize: eliminated hmask guard for forwarded HREFK.
    • debugging: added an (expensive) assertion to check GC objects in current stack upon trace exiting. thanks Mike Pall. only enabled when building with -DLUA_USE_ASSERT.
  • upgraded Lua Nginx Module to 0.9.13.
    • optimize: reduced the pool size of a fake connection from the default pool size (16KB) to 128B, affecting init_worker_by_lua and ngx.timer.at.
    • optimize: made fake requests share their connection pools, affecting init_worker_by_lua and ngx.timer.at.
    • feature: the error logger used by ngx.timer.at handlers now outputs the "client: xxx, server: xxx" context info for the original (true) request creating the timer.
    • feature: added nginx configuration file names and line numbers to the rewrite/access/content/log_by_lua directives' Lua chunk names in order to simplify debugging.
    • feature: ngx.flush(true) now returns the "timeout" and "client aborted" errors to the Lua land for the cases that writing to the client is timed out or the client closes the connection prematurely, respectively.
    • feature: ngx.flush(true) can now wait on delayed events due to nginx's limit_rate config directive or $limit_rate variable settings. thanks Shafreeck Sea for the original patch.
    • bugfix: ngx.flush(), ngx.eof(), and some other things did not update busy/free chains after calling the output filters.
    • bugfix: ngx_gzip/ngx_gunzip module filters might cause ngx.flush(true) to hang until timeout for nginx 1.7.7+ (and some other old versions of nginx). thanks Maxim Dounin for the help.
    • bugfix: ngx.get_phase() did not work in the context of init_worker_by_lua*.
    • bugfix: use of ngx.flush(true) with the limit_rate config directive or the $limit_rate variable may hang the request forever for large volumn of output data. thanks Shafreeck Sea for the report.
    • bugfix: compilation error when PCRE is disabled in the nginx build. thanks Ivan Cekov for the report.
    • bugfix: when syslog was enabled in the error_log directive for nginx 1.7.1+, use of init_worker_by_lua or ngx.timer.at() would lead to segmentation faults. thanks shun.zhang for the report.
    • bugfix: fixed compilation error with nginx 1.7.5+ because nginx 1.7.5+ changes the API in the events subsystem. thanks Charles R. Portwood II and Mathieu Le Marec for the report.
    • bugfix: ngx.req.raw_header(): buffer overflow and the "buffer error" exception might happen for massively pipelined downstream requests. thanks Dane Knecht for the report.
    • bugfix: ngx.req.raw_header(): we might change nginx's internal buffer pointers, which might cause bad side-effects.
    • doc: added a new section, Cocockets Not Available Everywhere, under the Known Issues section.
  • upgraded Lua Resty DNS Library to 0.14.
    • feature: added support for the SPF record type specified by RFC 4408. thanks Tom Fitzhenry for the patch.
  • upgraded Lua Resty Lrucache Library to 0.03.
    • feature: the get() method now also returns the stale value as the second returned value if available.
  • upgraded Lua Resty Lock Library to 0.04.
    • bugfix: the shared dictionary would incorrectly get unref'd for multiple times when the lock() and/or unlock() methods are called more than once. thanks Peng Wu for the report and Dejiang Zhu for the patch.
  • upgraded Echo Nginx Module to 0.57.
  • upgraded Drizzle Nginx Module to 0.1.8.
    • bugfix: fixed compilation error with nginx 1.7.5+ because nginx 1.7.5+ changes the API in the events subsystem.
  • upgraded Postgres Nginx Module to 1.0rc5.
