Documentation builds, but failing doctest in fast_callable.pyx
.
Would like more information on "overflow exceptions in cot/csc
", which is presumably this commit. What does this fix exactly?
The versioning is nonstandard. If this is a minor update it should be 0.6.9.1, otherwise 0.6.10.

Replying to paulmasson:

Curious. The doctest change seemeed necessary, but not anymore.

cot/csc
", which is presumably this commit. What does this fix exactly?
I think I explained this already. The only exact numeric value that can go into inverse()
is zero. All others are inexact. Otherwise the doctest that fails is:
File "src/sage/functions/trig.py", line 268, in sage.functions.trig.Function_cot.__init__ Failed example: cot(float(0)) Exception raised: Traceback (most recent call last): File "/home/ralf/sage/local/lib/python2.7/sitepackages/sage/doctest/forker.py", line 498, in _run self.compile_and_execute(example, compiler, test.globs) File "/home/ralf/sage/local/lib/python2.7/sitepackages/sage/doctest/forker.py", line 861, in compile_and_execute exec(compiled, globs) File "<doctest sage.functions.trig.Function_cot.__init__[16]>", line 1, in <module> cot(float(Integer(0))) File "sage/symbolic/function.pyx", line 996, in sage.symbolic.function.BuiltinFunction.__call__ (build/cythonized/sage/symbolic/function.cpp:11008) res = super(BuiltinFunction, self).__call__( File "sage/symbolic/function.pyx", line 488, in sage.symbolic.function.Function.__call__ (build/cythonized/sage/symbolic/function.cpp:6241) res = g_function_eval1(self._serial, OverflowError: numeric::inverse(): division by zero
The versioning is nonstandard. If this is a minor update it should be 0.6.9.1, otherwise 0.6.10.
Where do you get the idea of a standard for versioning? I could use ISO 8601 of the release date as well for the version string. There is a tradition to use major/minor/micro for Pynac, and I changed micro from 9 to 91 (ninety one) to stay lexicographically consecutive.

The traditional split indicates the use of semantic versioning. In semantic versioning numbers are incremented numerically, not lexicographically. See item (2) in this standard: http://semver.org

Nothing there forbids incrementing by 82.

Because of this change:

src/sage/functions/trig.py
diff git a/src/sage/functions/trig.py b/src/sage/functions/trig.py index 40c0586..fba1100 100644
a b class Function_cot(GinacFunction): 265 265 266 266 TESTS: 267 267 268 sage: cot(float(0)) 269 Infinity 270 sage: cot(SR(0)) 271 Infinity 272 sage: cot(float(0.1)) 273 9.966644423259238 274 sage: type(_) 275 <type 'float'> 276 268 277 Test complex input:: 269 278 270 279 sage: cot(complex(1,1)) # rel tol 1e15
The doc is incorrect. You need to change TESTS:
> TESTS::
.
Other than that, I would be willing to set this to a positive review unless Paul has any objections.

48dac6b  21623: doc fix

comment:13 Changed 5 years ago by
I have a problem with the version number. In semantic versioning, incrementing by 82 implies that many private releases in between versions, which clearly wasn't the case. This version number is inconsistent with the entire versioning history of Pynac.
This version number appears to be an arbitrary choice. As a belatedly recognized direct contributor to this version, I think it is well within my purview to request a modification. As more of the symbolics of Sage is moved into Pynac, I would like to see that project become more of a true collaboration. Changing the version on GitHub is a straightforward process and would give evidence of acceptance of feedback.
I don't think this ticket should be approved with the current version number.
comment:14 Changed 5 years ago by
I think this is in the realm of bikeshedding.
comment:15 Changed 5 years ago by
While I disapprove of the numbering, I don't care enough to make it an issue for inclusion/review.

Travis, since there is no review process for Pynac this is the only place to question arbitrary decisions made by one person. If you consider that trivial, so be it.
comment:17 followup: ↓ 19 Changed 5 years ago by
The Pynac review process happens here, nothing new. Maintainer decisions are often seen as arbitrary. I won't devote time to revert a numbering issue. Rather, I started yesterday on fast series expansion using Flint, which will make a new minor number change necessary because of the hard dependency. So if 0.6.91 doesn't get positive review it'll be replaced by 0.7.0 later, anyway. The numbering criticism is noted and will be followed when 0.7.10 is on the plate. Or if.

IMO, let's try to sneak this into the next Sage release. So I'm setting this to a positive review.
