qwzhou89 opened a new issue, #9878:
URL: https://github.com/apache/apisix/issues/9878
### Current Behavior
When I put the code to register a new variable inside my_hook.lua and
execute apisix reload, an error is output inside the logs
### Expected Behavior
There should be no mistakes.
### Error Logs
2023/07/21 06:53:10 [error] 1#1: init_by_lua error:
/usr/local/apisix/apisix/init.lua:21: changing jit stack size is not allowed
when some regexs have already been compiled and cached
stack traceback:
[C]: in function 'error'
/usr/local/openresty/lualib/ngx/re.lua:297: in function 'opt'
/usr/local/apisix/apisix/init.lua:21: in main chunk
[C]: in function 'require'
init_by_lua:4: in main chunk
### Steps to Reproduce
1.Run APISIX 2.15.3 in docker.
2.Modify 3 of the lines in conf/config-default.yaml as follows：
```shell
extra_lua_path: "/usr/local/apisix/conf/hook/?.lua" #
extend lua_package_path to load third party code
extra_lua_cpath: "" # extend lua_package_cpath to load third
party code
lua_module_hook: "my_hook" # the hook module which will be used to inject
third party code into APISIX
```
3.Create a new /usr/local/apisix/conf/hook/my_hook.lua file and insert the
following contents
(this is copied from
https://apisix.apache.org/docs/apisix/next/plugin-develop/#register-custom-variable)
```lua
local core = require "apisix.core"
core.ctx.register_var("a6_labels_zone", function(ctx)
local route = ctx.matched_route and ctx.matched_route.value
if route and route.labels then
return route.labels.zone
end
return nil
end)
```
4.Execute the `apisix reload` command
5.In the log there is the following output
```
