Package repositories now look like this: top-level-dir/ repo.yaml packages/ libelf/ package.py mpich/ package.py ... This leaves room at the top level for additional metadata, source, per-repo configs, indexes, etc., and it makes it easy to see that something is a spack repo (just look for repo.yaml and packages).

$spack/var/spack/repos/builtin From 34401cf0c3ee019fd6b8fb739e2a511c6de0870c Mon Sep 17 00:00:00 2001 From: Todd Gamblin Date: Fri, 25 Dec 2015 14:00:33 -0800 Subject: [PATCH 20/37] Rework Spack config: keep user & site config in memory. - User and site config are now kept separately in memory. - Merging is done on demand when client code requests the configuration. - Allows user/site config to be updated independently of each other by commands. - simplifies config logic (no more tracking merged files) --- .gitignore | 1 + lib/spack/spack/cmd/compiler.py | 7 +- lib/spack/spack/cmd/config.py | 12 +- lib/spack/spack/cmd/mirror.py | 4 +- lib/spack/spack/compilers/__init__.py | 76 ++-- lib/spack/spack/config.py | 409 +++++++++++---------- lib/spack/spack/spec.py | 1 + lib/spack/spack/stage.py | 5 +- lib/spack/spack/test/config.py | 21 +- lib/spack/spack/test/database.py | 3 +- lib/spack/spack/test/mock_packages_test.py | 6 +- 11 files changed, 281 insertions(+), 264 deletions(-) diff --git a/.gitignore b/.gitignore index 1c6ca4c99e1..4b97de5d507 100644 --- a/.gitignore +++ b/.gitignore @@ -8,3 +8,4 @@ /etc/spackconfig /share/spack/dotkit /share/spack/modules +/TAGS diff --git a/lib/spack/spack/cmd/compiler.py b/lib/spack/spack/cmd/compiler.py index 2a64dc914ed..6efc9a3347a 100644 --- a/lib/spack/spack/cmd/compiler.py +++ b/lib/spack/spack/cmd/compiler.py @@ -65,10 +65,11 @@ def compiler_add(args): if c.spec not in spack.compilers.all_compilers()] if compilers: -
