[3pt] Document Thoth's requirement for dependencies to be in an index

codificat commented 2 years ago

Problem statement

As a Thoth user, I am frustrated because Thoth can not provide advise about my application software stack, because my Pipfile references modules that are not hosted in a package index (local modules, file / git references).

For example:

And if I run thamos advise and my Pipfile contains an editable install:

$ thamos advise
2022-05-19 13:50:37,067 [163181] WARNING  thamos: Development dependencies will not be considered during the resolution process - see https://thoth-station.ninja/j/no_dev
2022-05-19 13:50:37,067 [163181] INFO     thamos.lib: Using Pipenv files to manage dependencies located in '/home/pep/github/os-climate/aicoe-osc-demo'
2022-05-19 13:50:37,067 [163181] INFO     thamos.lib: Submitting Pipfile.lock as a base for user's stack scoring - see https://thoth-station.ninja/j/user_stack
2022-05-19 13:50:37,068 [163181] ERROR    thamos: Failed to load Pipfile (path: /home/pep/github/os-climate/aicoe-osc-demo/Pipfile: Package 'src' is editable local project instead of a package from a package index

and it is unclear to me why this is an ERROR and how to fix it.

High-level Goals

Documentation exists, clearly reachable within the Thoth documentation, that explains:

why this is happening
what are the alternatives and their implications
how should I proceed so that Thoth can provide advice

Proposal description

Alternatives

Additional context

A blog post was published one year ago about this topic: https://developers.redhat.com/articles/2021/05/26/can-we-consider-editable-bad-practice

However, this is not part of Thoth's documentation.

Acceptance Criteria

Documentation in the Thoth website covers:

[ ] the requirements that my dependency specifications must meet
[ ] the reasoning behind these requirements
[ ] alternative options and their consequences
[ ] clear steps to help me meet the requirements
[ ] pointers and references to learn more about it

And based on that documentation:

[ ] create a follow-up issue so that entry points that fail due to unmet requirements provide links to the documentation about them

Given that the content of the documentation is heavily tied to the guidance service, this is /sig stack-guidance more than /remove-sig user-experience

This is delayed waiting for input from the alternative approaches and how they apply to a real-life use case, e.g. https://github.com/thoth-station/opendatahub-cnbi/issues/14
