From 054e308f5d85ca96327861a577d69c6e18fdc9dc Mon Sep 17 00:00:00 2001 From: Hartmut Goebel Date: Sun, 15 Nov 2020 21:25:16 +0100 Subject: [PATCH] import: crate: Use existing package satisfying semver requirement. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If a package satisfying the dependency's semver requirement already exists, use it. Prior to this change the highest version matching the semver requirement was used (and imported in case it was not defined as package already). When resolving a dependency (now done in `sort-map-dependencies`), first search for a package matching the semver requirement and only if this fails reach out for a crate. * guix/import/crate.scm (crate->guix-package)[find-package-version]: New function. [dependency-name+version]: New function. [sort-map-dependencies]: Use it instead of lambda function. * tests/crate.scm (test-doctool-crate, test-doctool-dependencies): New variables. ("self-test …", "cargo-recursive-import-hoors-existing-packages"): New tests. --- guix/import/crate.scm | 37 ++++++++++++++----- tests/crate.scm | 83 +++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 112 insertions(+), 8 deletions(-) diff --git a/guix/import/crate.scm b/guix/import/crate.scm index b133529ba7..3bc261b04e 100644 --- a/guix/import/crate.scm +++ b/guix/import/crate.scm @@ -32,6 +32,7 @@ #:use-module (guix packages) #:use-module (guix upstream) #:use-module (guix utils) + #:use-module (gnu packages) #:use-module (ice-9 match) #:use-module (ice-9 regex) #:use-module (json) @@ -92,7 +93,7 @@ (requirement crate-dependency-requirement "req")) ;string (module-autoload!
