Using a consistent numeric interpretation for timestamps, dates and
times simplifies a bunch of operations. It certainly simplifies
conversion between the Postgres formats.
Copied from TUWF::Validate with a few small changes. I have a few more
features planned, but let's see how this goes first.
It's been an incredibly useful module in the past, I'm not sure right
now if I had ideas for potential improvements at some point, will need
to check notes.
And with this, I have a working rewrite of the manned.org backend into
FU. \o/
The $st->row methods are very useful even for queries that may not
return anything, so their old behavior was unhelpful. Interestingly
enough, the error-on-multiple-rows did catch an actual bug in
Manned.org, so I'm keeping that behavior.
...I was hoping not to have to implement the date type, because date
conversions suck, but it turns out manned.org actually needs it.
(Only to then convert it into a Unix timestamp again, hmm, maybe this
string conversion isn't useful at all?)
What I'd really like, in addition to this, is a way to extract a query
from an $st object that can be run in the psql CLI. VNDB has a debugging
feature for that, but it's less trivial to make that work with binary
query parameters.
Realized that, since html_() now returns a string, it's just as easy to
just pass that to fu->set_body(); no need for integration complexity.
Combined import options don't save much typing, not worth the overhead
either.
And remove UTF-8 check in JSON writer. It honestly feels kind of silly
to do that validation there while I've never done similar validations in
any other output routines - including this XML writer.
FU::XMLWriter is a copy of TUWF::XMLXS with a bunch of improvements
applied: now uses refcounts to determine the current output instance,
auto-generates XS functions and has faster escaped string output -
inspired by the JSON writer.
TODO:
- Integrate into FU
- Do something with bool attribute values
- Benchmarks
- Should $content be optional for all tags? The reason they weren't in
TUWF::XMLXS is because TUWF::XML supports opening tags without closing
them, but that idea turned out to suck and isn't supported anymore.
This is hopefully the last XS module for the FU framework. The only C
code being written now should be bug fixes and extending FU::Pg with
some planned features. Already ended up with more C than I had
planned...
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 -.-
This shows I got some optimizing to do. I was expecting integer parsing
to be slower, though, but it looks like it can compete with JSON::XS's
specialized small-int parsing code anyway.
That completes the json_format() function for now. At least, it now does
everything I had planned for it.
Ended up at a bit over 300 LOC. That's larger than I had expected, but
still alright.
