logging memory address of a table

[ms2008]

Is there a way to log the table's address by ngx.log? Just same as PUC Lua print({}) outputs table: 0xcc1e00 . This feature would be extremely useful for debugging the weak table related issues.

@ms2008 Just use the tostring() Lua API function yourself to generate such strings.

@ms2008 A quick example:

$ resty -e 'ngx.log(ngx.WARN, tostring{ dog = 3 })'
2019/01/19 12:58:32 [warn] 898#898: *2 [lua] (command line -e):1: table: 0x7f25a530f508, context: ngx.timer
