[Starlingx-discuss] build-pkg --parallel

[Hu, Yong]

It is awesome!!
Running “create_dependancy_cache.py” against the mirror (of RPMs) is to generate a new “dependancy-cache”, isn’t it?

Subject: [Starlingx-discuss] build-pkg --parallel


I had a successful parallel build (aka build-pkgs --parallel) inside the docker container.   ~1h45m on 24 core, 64G ram

The prerequisite was a populated $MY_REPO/cgcs-tis-repo/dependancy-cache.

Currently we only generate the cache after the build in the 'generate-cgcs-tis-repo' step.  I'd like to see the cache stored in git and updated regularly by 'official' builds.

Note: The cache doesn't have to be perfect, so a cache that is out of date by a day or a week is still very useful.  build-pkgs/mockchain just needs a rough guide on build dependencies and potential dependency loops.
