EXEC : possible to update pairs directly?

[FRANKS, Andy (SHREWSBURY AND TELFORD HOSPITAL NHS TRUST)]

Thanks Alan.

>>   Sorry.  :(  We're working on it, but there's a ton of things to fix in v4.

I just appreciate you've done this thing you can download for free, put your time into it, believe in open source. I've little room to grumble. :-)

>> Arran's wrong!
Lol!
For now, I'll just update when "back in" freeradius, copy attributes over, it's not too bad.

Alternatively I guess I could work a bit more on getting 3.1 working again, that's been working here for years now perfectly, but it no longer compiles.

>> Perl in v4 still works.
I'll have to look into Perl with mysql, if it works as is reliable and quick, then it should be a possibility. I'd always thought perl was a bit "yesterday" according to general thinking, but I'm not overly bothered by that.
I've dabbled with Python, but lack the knowledge around creating full modules, rather than "scripts", I should just learn I guess!

Thanks again
Andy

  Sorry.  :(  We're working on it, but there's a ton of things to fix in v4.

  I'm pretty sure that doesn't work.  In v3, the "exec" parsing uses the same code path as used by the "files" module.  Which doesn't support list qualifiers.

  Arran's wrong!

> Also happy taking advice on how best to replicate sql maps and attribute pair functionality best, possibly in python or perl I suppose, although those seem more "fixed" at a glance than exec.

  Perl in v4 still works.
