# Types of CI pipelines:
# | pipeline name        | context   | description                                                 |
# |----------------------|-----------|-------------------------------------------------------------|
# | merge pipeline       | mesa/mesa | pipeline running for an MR; if it passes the MR gets merged |
# | pre-merge pipeline   | mesa/mesa | same as above, except its status doesn't affect the MR      |
# | post-merge pipeline  | mesa/mesa | pipeline immediately after merging                          |
# | fork pipeline        | fork      | pipeline running in a user fork                             |
# | scheduled pipeline   | mesa/mesa | nightly pipelines, running every morning at 4am UTC         |
# | direct-push pipeline | mesa/mesa | when commits are pushed directly to mesa/mesa, bypassing Marge and its gating pipeline |
#
# Note that the release branches maintained by the release manager fall under
# the "direct push" category.
#
# "context" indicates the permissions that the jobs get; notably, any
# container created in mesa/mesa gets pushed immediately for everyone to use
# as soon as the image tag change is merged.
#
# Merge pipelines contain all jobs that must pass before the MR can be merged.
# Pre-merge pipelines contain the exact same jobs as merge pipelines.
# Post-merge pipelines contain *only* the `pages` job that deploys the new
# version of the website.
# Fork pipelines contain everything.
# Scheduled pipelines only contain the container+build jobs, and some extra
# test jobs (typically "full" variants of pre-merge jobs that only run 1/X
# test cases), but not a repeat of the merge pipeline jobs.
# Direct-push pipelines contain the same jobs as merge pipelines.
