"""finalize_evidence.py — REQ-10 / D-028 / D-029
|
|
|
|
Uploads (PUT or POST) a local `audit.json` to the `acdl-evidence` repo on
|
|
Gitea via the file-contents API. Used by the pipeline workflow steps to
|
|
persist the hash-chained audit trail to `acdl-evidence` between dispatches
|
|
(D-028 state-persistence across re-dispatches; D-029 finalize step).
|
|
|
|
Uses only the Python standard library (urllib.request) so it has no
|
|
external dependency on `requests`. Auth header: `Authorization: token <token>`.
|
|
|
|
Input (argv flags):
|
|
--audit <path> (required) local audit.json file to upload
|
|
--owner <org> (optional, default continuous-intelligence)
|
|
--repo <name> (optional, default acdl-evidence)
|
|
--branch <name> (optional, default main)
|
|
--path <remote path> (optional, default audit.json) path in the repo
|
|
--token-env <env var> (optional, default ACDL_GITEA_TOKEN)
|
|
--host <url> (optional, default https://git.cloudinit.dev)
|
|
--message <commit msg> (optional, default chore(evidence): update audit.json)
|
|
|
|
Behavior:
|
|
1. Read the token from os.environ[token_env]. Missing -> stderr + exit 1.
|
|
2. Read the local audit file; base64-encode it.
|
|
3. GET the current file at .../contents/<path>?ref=<branch> to discover
|
|
the existing `sha`. 200 -> capture sha (update mode). 404 -> no sha
|
|
(create mode). Other errors -> exit 1.
|
|
4. If sha set: PUT with body {content, message, branch, sha}.
|
|
If no sha: POST with body {content, message, branch}.
|
|
5. Print {"uploaded": true, "path": "<path>", "sha": "<new sha>"} to
|
|
stdout and exit 0.
|
|
6. On any HTTP error: print
|
|
{"uploaded": false, "status": <code>, "body": "<body>"} to stdout
|
|
and exit 1.
