Tom Lane	5c4c771daf	Revert "Test conversion of NaN between float4 and float8." ... This reverts commit 55e0e45817. It's served its purpose of demonstrating what was wrong on buildfarm member opossum. We could consider putting some kind of single-purpose hack into ftod() to make the test pass there; but I don't think it's worth the trouble, since there are surely many other places whether this platform bug could manifest.	8 years ago
Tom Lane	55e0e45817	Test conversion of NaN between float4 and float8. ... Results from buildfarm member opossum suggest that this doesn't work quite right on that platform. We've seen issues with NaN support on MIPS/NetBSD before ... allegedly they fixed this stuff back in 2010, but maybe only for small values of "fixed". If, in fact, opossum fails this test then I plan to revert it; it's mainly for diagnostic purposes rather than something we'd necessarily keep long-term. I think that the failures in window.sql could be worked around with some code duplication, but I want to verify my theory about the cause first.	8 years ago
Peter Eisentraut	fc946c39ae	Remove useless whitespace at end of lines	15 years ago
Peter Eisentraut	3f11971916	Remove extra newlines at end and beginning of files, add missing newlines ... at end of files.	16 years ago
Tom Lane	4d17a2146c	Insert a hack into get_float8_nan (both core and ecpg copies) to deal with ... the fact that NetBSD/mips is currently broken, as per buildfarm member pika. Also add regression tests to ensure that get_float8_nan and get_float4_nan are exercised even on platforms where they are not needed by float8in/float4in. Zoltán Böszörményi and Tom Lane	16 years ago
Bruce Momjian	f9ac414c35	Fix float4/8 to handle Infinity and Nan consistently, e.g. Infinity is a ... valid result from a computation if one of the input values was infinity. The previous code assumed an operation that returned infinity was an overflow. Handle underflow/overflow consistently, and add checks for aggregate overflow. Consistently prevent Inf/Nan from being cast to integer data types. Fix INT_MIN % -1 to prevent overflow. Update regression results for new error text. Per report from Roman Kononov.	19 years ago
Neil Conway	f5ab0a14ea	Add a "USING" clause to DELETE, which is equivalent to the FROM clause ... in UPDATE. We also now issue a NOTICE if a query has _any_ implicit range table entries -- in the past, we would only warn about implicit RTEs in SELECTs with at least one explicit RTE. As a result of the warning change, 25 of the regression tests had to be updated. I also took the opportunity to remove some bogus whitespace differences between some of the float4 and float8 variants. I believe I have correctly updated all the platform-specific variants, but let me know if that's not the case. Original patch for DELETE ... USING from Euler Taveira de Oliveira, reworked by Neil Conway.	21 years ago
Neil Conway	975e27377a	Adjust input routines for float4, float8 and oid to reject the empty string ... as valid input (it was previously treated as 0). This input was deprecated in 8.0 (and a warning was emitted). Regression tests updated.	21 years ago
Neil Conway	bfd6f52b0e	Allow 'Infinity' and '-Infinity' as input to the float4 and float8 ... types. Update the regression tests and the documentation to reflect this. Remove the UNSAFE_FLOATS #ifdef. This is only half the story: we still unconditionally reject floating point operations that result in +/- infinity. See recent thread on -hackers for more information.	22 years ago
Neil Conway	e2ded829f6	Revise int2/int4/int8/float4/float8 input routines to allow for ... any amount of leading or trailing whitespace (where "whitespace" is defined by isspace()). This is for SQL conformance, as well as consistency with other numeric types (e.g. oid, numeric). Also refactor pg_atoi() to avoid looking at errno where not necessary, and add a bunch of regression tests for the input to these types.	22 years ago
Thomas G. Lockhart	61ef6a1a3f	Clean up syntax to use SQL92-ish type coersion ... rather than the Postgres "::" notation. All of these tests have been completely inspected and give correct results.	26 years ago
Thomas G. Lockhart	83b8cf5b6b	Add inter-type regression tests for geometry, date/time, and numbers. ... Add regression tests for circles, line segments, and paths. Modify regression tests to allow GEQ optimizer (order results).	29 years ago
Marc G. Fournier	3451abf632	Make these self-contained tests...they are testing types, so the tables ... that are created should only exist as long as the test requires them... things are just toooooo spread around	29 years ago
Marc G. Fournier	04688df668	Again, add more tests	29 years ago
