The list of
CASA supported OSs has grown from 2 (RHEL 4.x and one version of OS X) to 7, and there is ongoing pressure to increase support. CASA has been trying to distribute native packages for both 3rd party development tools and published CASA packages. At this time, CASA is not meeting OS support requirements, and does not look like it can within available resources.
Evaluate cross platform package managers to see if any help reduce the work of delivering CASA 3rd party packages to developers and CASA packages to users enough to offset the costs of adoption.
Status: See
CAS-5685.

Plan
- Collect requirements.
- Collect candidates.
- Eliminate candidates as quickly as possible.
- For each of the top three remaining candidates.
- Try with trivial example
- Try with non-trivial example
- Evaluate
Deliverables
- Requirements used to evaluate candidates.
- List of all candidates evaluated.
- For each reject, give reason.
- Report comparing top three candidates, with recommendation.
- Admin instructions for setting up candidate for use by users.
- User instructions for using candidate to install CASA 3rd party packages for developers.
- User instructions for using candidate to install CASA packages for users.
Requirements
Candidate cross platform package managers must meet these requirements:
- Co-exist with native platform package managers for all CASA supported OSs.
- Allow us to override platform packages without breaking other software on that platform.
- Allow us to install several consistent sets of CASA 3rd party packages and CASA packages at the same time without interfering with each other. For example, to support old and new 3rd party packages while transitioning between versions.
- Not require complex configuration by users.
- Allow CASA to deliver binary packages.
- Minimize the number of platforms we must build on before publishing packages.
- Allow users to install binary packages where they like (and have write permission), without rebuilding.
- Allow users to setup a developer environment easily.
- Must not cause CASA to run more slowly.
