A directory context_dir containing a Dockerfile will be assembled into a gzipped tar file at out_path.

We also scan the source Dockerfile for special syntax that influences context generation.

If a line in the Dockerfile has the form # %include <path>, the relative path specified on that line will be matched against files in the source repository and added to the context under the path topsrcdir/. If an entry is a directory, we add all files under that directory.

Returns the SHA-256 hex digest of the created archive.

gecko_taskgraph.util.docker.stream_context_tar(topsrcdir, context_dir, out_file, image_name, args)

gecko_taskgraph.util.scriptworker module

Make scriptworker.cot.verify more user friendly by making scopes dynamic.

Scriptworker uses certain scopes to determine which sets of credentials to use. Certain scopes are restricted by branch in chain of trust verification, and are checked again at the script level. This file provides functions to adjust these scopes automatically by project; this makes pushing to try, forking a project branch, and merge day uplifts more user friendly.

In the future, we may adjust scopes by other settings as well, e.g. different scopes for push-to-candidates rather than push-to-releases, even if both happen on mozilla-beta and mozilla-release.

Additional configuration is found in the graph config.

gecko_taskgraph.util.verify module

class gecko_taskgraph.util.verify.DocPaths(paths=NOTHING)

Bases: object

add(path)

Projects that make use of Firefox’s taskgraph can extend it with their own task kinds by registering additional paths for documentation. documentation_paths.add() needs to be called by the project’s Taskgraph registration function. See taskgraph.config.

get_files(filename)

gecko_taskgraph.util.verify.verify_aliases(task, taskgraph, scratch_pad, graph_config, parameters)

gecko_taskgraph.util.verify.verify_run_known_projects(task, taskgraph, scratch_pad, graph_config, parameters)

Validates the inputs in run-on-projects.

We should never let ‘try’ (or ‘try-comm-central’) be in run-on-projects even though it is valid because it is not considered for try pushes. While here we also validate for other unknown projects or typos.
