PANIC: unprotected error in call to Lua API (attempt to index a nil value) #298

Open centminmod opened 6 years ago

centminmod commented 6 years ago

I install Wrk via git clone on CentOS 7.4 64bit systems. Usually it works fine except for one system I get the following error when running wrk with parameters

I'm getting this error using wrk package from Ubuntu 18.04 which is also 4.0.2-2 version, did you manage to make it work?

centminmod commented 6 years ago

i just use make these days works on my forked wrk branch

Experiencing this with Mint 19

me too

landon30 commented 5 years ago

i occurs the runtime error，but i solved

  1. ensure the compile-make luajit is same with the ldd dependency luajit
  2. it occurs when the system LD_LIBRARY_PATH has a luajit，this luajit is not same with the compile luajit

Same issue on Debian 9:

Package: wrk

State: installed
Automatically installed: no

Uncompressed Size: 116 k
Depends: libc6 (>= 2.14), libluajit-5.1-2, libssl1.1 (>= 1.1.0)
Description: HTTP benchmarking tool
 wrk is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It combines a multithreaded design
 with scalable event notification systems such as epoll and kqueue. 

 An optional LuaJIT script can perform HTTP request generation, response processing, and custom reporting.

On Debian 9, the default libluajit-5.1-2 version is 2.0.4+dfsg-1+b1. If you're running on backports luajit (2.1.0~beta3+dfsg-5.1~bpo9+1), you need to recompile wrk.

I'm getting the same on macos with clang-12 after stripping the binary:

$ file wrk
wrk: Mach-O 64-bit executable x86_64
$ otool -L wrk
wrk:
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1292.60.1)
    /opt/pkg/lib/libssl.1.1.dylib (compatibility version 1.1.0, current version 1.1.0)
    /opt/pkg/lib/libcrypto.1.1.dylib (compatibility version 1.1.0, current version 1.1.0)
$ ./wrk -c 1 -t 1 http://localhost
unable to connect to localhost:http Connection refused
$ strip wrk
$ ./wrk -c 1 -t 1 http://localhost
PANIC: unprotected error in call to Lua API (attempt to index a nil value)

Have no idea what's the real reason. I'm building wrk with static LuaJIT, and I don't have any LuaJIT libs in the system.

UDPATE: it is failing in https://github.com/wg/wrk/blob/master/src/script.c#L102:

$ nm wrk.orig | fgrep luaJIT_BC
0000000100080460 S _luaJIT_BC_wrk
$ nm wrk.stripped | fgrep luaJIT_BC
$

Looks interesting.

this do solve my problem！

Still happening in Ubuntu 23.10 :(

@centminmod Thanks your fork is working on WSL https://github.com/centminmod/wrk/tree/centminmod

I've been receiving some messages, I don't know if this is normal

Same problem here with this script.
