[SR-11250] Different behavior during testing between Xcode and SPM #53651
Comments
|
Comment by Daniel Müllenborn (JIRA) I found out that the following code cannot be compiled correctly with SPM. import Foundation
precedencegroup ExponentiationPrecedence {
associativity: right
higherThan: MultiplicationPrecedence
}
infix operator **: ExponentiationPrecedence
infix operator **=: AssignmentPrecedence
extension Double {
static func ** (lhs: Double, rhs: Double) -> Double {
return pow(lhs, rhs)
}
static func **= (lhs: inout Double, rhs: Double) {
lhs = lhs ** rhs
}
}
let az: Double = 2.737712023738262
let el: Double = 0.4587429800191673
let beta: Double = 0
let sfaz: Double = 0
let theta: Double = (cos(az - sfaz) / abs(cos(az - sfaz)) * 180
/ .pi * acos(sqrt(1 - (cos(el - beta) - cos(beta) * cos(el)
* (1 - cos(az - sfaz))) ** 2)))
print(theta) // prints "nan" only when build with SPM |

Hm, I'm not seeing this with a non-dev build. DanielM (JIRA User), did you get your 5.1 from a downloadable toolchain, or did you build it yourself? |
|
And with master I get failures both in Xcode and in SwiftPM. So I'm going to assume that Xcode wasn't actually using your toolchain for whatever reason and hand this over to the stdlib folks. @stephentyrone? |
|
Comment by Daniel Müllenborn (JIRA) I also installed the Swift for TensorFlow Toolchain 0.4RC4, maybe this is the reason. |
|
Comment by Daniel Müllenborn (JIRA) I checked the SPM version again, and noticed that I accidentally used the TensorFlow toolchain. |
|
Comment by Daniel Müllenborn (JIRA) I think this bug should be fixed by your team. |

Environment
macOS 10.14.6
Xcode 11 beta5
Swift version 5.1-dev (LLVM af1f73e9e9, Swift 76e4d7f5ab)
Swift Package Manager - Swift 5.1.0 (1e376cb3)

Issue Description:
I have a test for an angle calculation, in Xcode the test is successful, but if I use SPM to run the test, the calculation returns "nan" and the test fails. I've added a small project to show the strange behavior of SPM.
