#!/usr/bin/env lucicfg
#
# This is the LUCI configuration for the 'chromium-website' project,
# the set of machines that build and test changes for the static website
# deployed to serve www.chromium.org.
#
# The chromium website needs basically the simplest possible LUCI project:
# one presubmit (aka "try") builder and one postsubmit (aka "CI" or
# continuous integration) builder, with the following conventions:
#
# - The project is called PROJECT_NAME.
# - The repo containing the LUCI configuration is found in PROJECT_REPO.
# - The recipes are found in the same repo as the rest of the LUCI config
#   (which is likely also the main repo for the project source code).
# - The builders will run in LUCI's public flex pools.
# - The builders will be configured into two different buckets, called "try"
# - and "ci"
# - The builders will be named $PROJECT_NAME-$BUCKET-builder
# - The builders will use the same recipe, found in
#   //infra/config/recipes/$PROJECT_NAME.py

# This should match the LUCI project name.
#
# In order to aid with grepping for occurrences of the project name
# in various other names, we repeat the string, below in some places,
# rather than using string interpolation. This means that if you change
# the project name, you should also do a search-and-replace for other
# occurrences of the string in this file.
PROJECT_NAME = "chromium-website"

# TODO(dpranke): Update this once the production repo is populated.
PROJECT_REPO = "https://chromium.googlesource.com/experimental/website"

# TODO(dpranke): Update this when/if you get a custom logo.
PROJECT_LOGO = "https://storage.googleapis.com/chrome-infra-public/logo/chromium.svg"

RECIPE_CIPD_PACKAGE = "infra/recipe_bundles/chromium.googlesource.com/chromium/tools/build"
RECIPE_NAME = 'chromium_website'

#
# Everything below this comment should be almost completely generic; however,
# in some places we explicitly expand $PROJECT_NAME rather than using
# string interpolation to aid in grepping for strings / code search.
# See the note above for more.
