Alvaro Herrera	f2c587067a	Rethink how to get float.h in old Windows API for isnan/isinf ... We include <float.h> in every place that needs isnan(), because MSVC used to require it. However, since MSVC 2013 that's no longer necessary (cf. commit cec8394b5c), so we can retire the inclusion to a version-specific stanza in win32_port.h, where it doesn't need to pollute random .c files. The header is of course still needed in a few places for other reasons. I (Álvaro) removed float.h from a few more files than in Emre's original patch. This doesn't break the build in my system, but we'll see what the buildfarm has to say about it all.

Tom Lane	93b6e03ab4	Fix jsonb_plperl to convert Perl UV values correctly. ... Values greater than IV_MAX were incorrectly converted to SQL, for instance ~0 would become -1 rather than 18446744073709551615 (on a 64-bit machine).

Tom Lane	1731e3741c	Fix excessive enreferencing in jsonb-to-plperl transform. ... We want, say, 2 to be transformed as 2, not \\2 which is what the original coding produced. Perl's standard seems to be to add an RV wrapper only for hash and array SVs, so do it like that. This was missed originally because the test cases only checked what came out of a round trip back to SQL, and the strip-all-dereferences loop at the top of SV_to_JsonbValue hides the extra refs from view. As a better test, print the Perl value with Data::Dumper, like the hstore_plperlu tests do. While we can't do that in the plperl test, only plperlu, that should be good enough because this code is the same for both PLs. But also add a simplistic test for extra REFs, which we can do in both. That strip-all-dereferences behavior is now a bit dubious; it's unlike what happens for other Perl-to-SQL conversions. However, the best thing to do seems to be to leave it alone and make the other conversions act similarly. That will be done separately.

Peter Eisentraut	e348e7ae57	Prevent infinity and NaN in jsonb/plperl transform ... jsonb uses numeric internally, and numeric can store NaN, but that is not allowed by jsonb on input, so we shouldn't store it. Also prevent infinity to get a consistent error message. (numeric input would reject infinity anyway.)

Tom Lane	331b2369c0	Fix platform and Perl-version dependencies in new jsonb_plperl code. ... Testing SvTYPE() directly is more fraught with problems than one might think, because depending on context Perl might be storing a scalar value in one of several forms, eg both numeric and string values. This resulted in Perl-version-dependent buildfarm test failures. Instead use the SvTYPE test only to distinguish non-scalar cases (AV, HV, NULL). Disambiguate scalars by testing SvIOK, SvNOK, then SvPOK. This creates a preference order for how we will resolve cases where the value is available in more than one form, which seems fine to me. Furthermore, because we're now dealing directly with a "double" value in the SvNOK case, we can get rid of an inadequate and unportable string-comparison test for infinities, and use isinf() instead. (We do need some additional #include and "-lm" infrastructure to use that in a contrib module, per prior experiences.) In passing, prevent the regression test results from depending on DROP CASCADE order; I've not seen that malfunction, but it's trouble waiting to happen.

Tom Lane	d4a4c3d5b4	Suppress compiler warning in new jsonb_plperl code. ... Some compilers are evidently pickier than others about whether Perl's I32 typedef should be considered equivalent to int. Dodge the problem by using a separate variable; the prior coding was a bit confusing anyway. Per buildfarm. Note this does nothing to fix the test failures due to SV_to_JsonbValue not covering enough variable types.	7 years ago
Peter Eisentraut	341e166180	Transforms for jsonb to PL/Perl ... Add a new contrib module jsonb_plperl that provides a transform between jsonb and PL/Perl. jsonb values are converted to appropriate Perl types such as arrays and hashes, and vice versa.
