* packages: Rewrite 'transitive-inputs' to be linear and remove duplicates.Ludovic Courtès2015-07-12
| | | | | | | | | | | | | | | | | | | | | | | There were two issues: 1. Use of 'delete-duplicates', which is quadratic, was a serious problem for closures with lots of propagated inputs, such as that of the 'hydra' package (several minutes for 'guix build hydra -n'!). 2. The 'delete-duplicates' call essentially had no effect since duplicate inputs typically had a different label and were thus kept. For instance, (bag-transitive-inputs (package->bag inkscape)) would return 216 items whereas (delete-duplicates (map cdr THAT)) contains only 67 items. The new implementation returns 67 items in this case. For 'hydra', we're down from 42211 items to 361, and roughly 13s for 'guix build hydra'. * guix/packages.scm (transitive-inputs): Rewrite as a breadth-first traversal. Remove duplicate propagated inputs. * tests/packages.scm ("package-transitive-inputs", "package->bag, propagated inputs"): Adjust to use simple labels for propagated inputs, without "/".
