Hi Guix,
Consider the following manifest:
Toggle snippet (25 lines)
(use-modules (guix packages)
(guix profiles)
(guix utils)
(gnu packages))
(define %qt-major-version "6")
(manifest
(map package->manifest-entry
(fold-packages
(lambda (package lst)
(let ((uri (and=> (package-source package)
(lambda (x)
(and (origin? x)
(origin-uri x))))))
(if (and uri
(string? uri)
(string-prefix? "mirror://qt/" uri)
(= %qt-major-version (version-major
(package-version package))))
(cons package lst)
lst)))
'())))
There's a subtle bug in it, which is the '=' function which is used
instead of 'string=?'. I'd expect 'guix refresh -m qt-manifest.scm' to
let this exception interrupt execution, but instead it proceeds to
refresh all (?) the packages (taking a long time to compute).
At the REPL, the error is reported as:
Toggle snippet (4 lines)
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
In procedure =: Wrong type argument in position 1: "6"

Thanks,
Maxim
