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	eac93e20af	Remove less-portable-than-believed test case. ... In commit 331b2369c I added a test to see what jsonb_plperl would do with a qr{} result. Turns out the answer is Perl version dependent. That fact doesn't bother me particularly, but coping with multiple result possibilities is way more work than this test seems worth. So remove it again. Discussion: https://postgr.es/m/E1f3MMJ-0006bf-B0@gemulon.postgresql.org	7 years ago
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.

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.
