# This script builds the perfetto.dev docs website (via ./build) and pushes the
# contents to the gs://perfetto.dev GCS bucket. It doesn't re-deploy the
# AppEngine instance, as that doesn't depend on the contents (use
# ./appengine/deploy for that).
# This is ran by the Cloud Build infrastructure (./cloudbuild.yaml) whenever a
# docs/ change is detected. See go/perfetto-ui-autopush for more details.

# The markdown docs are rendered into extension-less HTML files to make the URLs
# look nice (e.g., /docs/tracing rather than /docs/tracing.html). By default
# gsutil infers the mime-type from the extension, falling back to octet/stream
# for extension-less fiels. octect/stream causes the browser to download the
# file rather than parsing it as a web page.
# We set use_magicfile = True here, which causes gsutil to infer the MIME type
# by invoking `file -b --mime /path/to/file`.
# Unfortunately, that solves the HTML MIME problem but adds another one: the
# standard `file` util doesn't deal with .css files and marks them as text/plain
# causing the browser to ignore the CSS.
# Here what we do is replacing the standard `file` util with a custom made one
# (mime_util/file) which sets the right MIME types we want. We do this by
# prepending our script to the PATH.
