… in current stack upon trace exiting. thanks Mike Pall." This reverts commit aa8fc2e.
The Lua API can be used like below: local exdata = require "thread.exdata" exdata(0xdeadbeefLL) -- set the exdata of the current Lua thread local ptr = exdata() -- fetch the exdata of the current Lua thread The exdata value on the Lua land is represented as a cdata object of the ctype "void*". Right now the reading API, i.e., `exdata()` calls without any arguments, can be JIT compiled. Also exposed the following public C API functions for manipulating exdata on the C land: void lua_setexdata(lua_State *L, void *exdata); void *lua_getexdata(lua_State *L); The exdata pointer is initialized to NULL when the main thread is created. Any child Lua threads created will inherit the parent's exdata but still have their own exdata storage. So child Lua threads can always override the inherited parent exdata pointer values. This API is used internally by the OpenResty core so never ever mess with it yourself in the context of OpenResty. Thanks Zexuan Luo for preparing the final version of the patch.

This Lua API can be JIT compiled.
Returns true when the table contains non-nil array elements or non-nil
key-value pairs.
Usage:
```lua
local isempty = require "table.isempty"
print(isempty({})) -- true
print(isempty({nil, dog = nil})) -- true
print(isempty({"a", "b"})) -- false
print(isempty({nil, 3})) -- false
print(isempty({cat = 3})) -- false
```

…eturns true for purely array-like Lua tables and false otherwise.
Empty Lua tables are treated as arrays.
Use it like this:
isarr = require "table.isarray"
print(isarr{"a", true, 3.14}) -- true
print(isarr{"dog" = 3}) -- false
print(isarr{}) -- true

This Lua builtin returns the number of elements in a Lua table, i.e.,
the number of non-nil array elements plus the number of non-nil key-value
pairs in a single Lua table.
It can be used like this:
local nkeys = require "table.nkeys"
print(nkeys({})) -- 0
print(nkeys({ "a", nil, "b" })) -- 2
print(nkeys({ dog = 3, cat = 4, bird = nil })) -- 2
print(nkeys({ "a", dog = 3, cat = 4 })) -- 3
This Lua API can be JIT compiled.

…a stack traversal code. thanks Thibault Charbonnier for the report in #40.
…se-after-free issues and memory corruptions. Fix #42.
doc: also mentioned our own bugfixes in LuaJIT's JIT compiler and VM. Fix #39.
The unsinking code was not using the correct layout for GC64 IR constants (value in adjacent slot) for this case. This patch is a derivative of raptorjit/raptorjit#246 ported for LuaJIT itself. Fixed after an intense debugging session with @lukego. Co-authored-by: Luke Gorrie <lukego@gmail.com>
