I liked the Perl implementation of transactions, but managing state
between Perl and C is a bit cumbersome, so I've moved the whole thing
into C.
Also added a few statement configuration methods that currently don't do
anything yet.
Partly because some errors currently appeared to come from within FU::PG
itself, which is useless, and partly because it's common to wrap
database access methods, while that's exactly the kind of operation
where you *really* want to know where the error originated from.
(Source: too much time wasted debugging VNDB errors)
Was expecting the implementation of this to get overly complicated and
brittle, but using a counter-based cookie and doing parts of it in Perl
made it pretty easy actually. Pretty happy with how this turned out so
far.
TODO: documentation -.-
Going to need a way to pass arguments into the XS function anyway, so
might as well do the entire arg parsing step in XS while we're at it.
Provides a significant speedup for tiny inputs as well, but I don't find
that too interesting.
It works and can format all "plain" Perl data, but has a few known bugs
and limitations that still need to be worked out.
It's about 8x smaller than JSON::XS's encoder and *much* smaller than
Cpanel::JSON::XS, but this is just a first attempt, it'll grow.
