#1 Performance imp (for nested loops and many vars)

[Köster Georg]

Hi Andrei,

the current code copies on every loop-entry all of the variables into a new map, so that it can overwrite parent vars with local variables.
That is exponential complexity - too much in my case.

Here I propose using a chainable map - which brings the complexity as far as loop-nesting and variables are concerned.

Thanks for providing this code, it has helped us get up to speed quickly!
Cheers,
Georg

Georg,

Do your tests pass with the patch? I ran this with GCC 4.4.5, and I get segmentation faults when trying to create a reference test file, as in: ./test create t/loop.tmpl

Andrei,

currently I don't have a dev environment for Linux, sorry.

At the time it was running well, even in production. I really don't remember if I ran the tests! But certainly if I didn't run them, than because they didn't work right from the start. I guess you checked for that already. ; )

I am not joking about the speed : )

Best regards,
Georg
