I'm not sure if this is gonna work on all supported compilers. We also target C89 so definitions has to be at the beginning of block.

Considering that VLA is C99, you can't really use it though.

@tback I think that memory allocation is a small overhead and this (status) is definitely not a perf critical path so I wouldn't worry about that. As I mentioned, you can't use VLA so there is not much options anyway... :) The It will go to 7.1 so if you could target it, that would be great! Thanks for your work! |

@bukka: I decided against implementing
fpm_scoreboard_copyfor now. The way I did it avoids explicit memory management because the scoreboard copies are put on the stack.I don't know exactly what php version introduced the fpm status page, but I know the code was present in 5.5 already.
