Turns out this is necessary even if the fd is going to be passed through
exec() soon, because the supervisor might receive multiple fds before
spawning another process, in which case all of them are going to be
passed to the new process instead of just one.
Most of these are binary strings and shouldn't be interpreted as C
strings in the first place, but better be safe in case they are, anyway.
The lack of nul-termination of FU::Pg `$hex` strings was more likely to
be problematic.
And use it for automatic output compression in FU, as (potentially)
faster alternative to Compress::Raw::Zlib.
Was also planning to maybe add support for Zstd or Brotli, but given the
performance of libdeflate, I'm not sure that's really necessary. Brotli
does tend to do a better job at compressing HTML, though.
I'm breaking stuff left and right while I still can.
Idea: "key_names" validation?
Idea: "tuple" validation that works like "keys" but for arrays.
(i.e. { tuple => { $index => $schema } }, could make "missing" and
"unknown" work for arrays, too)
This allows all built-in options to be duplicated inside a single
schema, the semantics of which are the same as the kind of merging
done as part of inheriting options from custom validations.
This also causes all 'keys' and 'values' validation schemas to be
merged, which changes error messages a bit but is great for
introspection. Probably slightly improves performance as well.
API is not super convenient and implementation is lousy, but uploading
files is not a super common operation so that should be fine.
At least it supports large files with only a single in-memory copy.
Using a consistent numeric interpretation for timestamps, dates and
times simplifies a bunch of operations. It certainly simplifies
conversion between the Postgres formats.
Compress::Zstd decided to bundle libzstd instead of linking to the
system lib, and it predictably hasn't been updated in 6 years. I
consider that broken to the point of DO-NOT-USE.
Maybe I'll do a custom dlopen() wrapper for that later, but for now
let's just stick with gzip.
