Add tools/build_wiki.py, which builds the five English wiki pages into wiki/, rewrites links so they work inside the wiki and reports pages that differ from their sources. Offline tests cover the conversion and assert that the committed pages are current. Task: MIL-005#3

# Workflow credentials
|
|
|
|
The sync workflow uses two secrets. Give each the least privilege that works,
|
|
store it only as a Gitea secret, and rotate it when a person with access
|
|
leaves.
|
|
|
|
| Secret | Content | Used for |
|
|
| --- | --- | --- |
|
|
| `TOKEN_FOR_GITEA` | A bare token, a JSON string, or JSON with `GITEA_TOKEN` | Reading the repository (description, topics) and its push mirrors |
|
|
| `CREDENTIALS_FOR_GITHUB` | JSON object with a non-empty `GITHUB_PAT` | Changing the description and topics of the GitHub mirror |
|
|
|
|
## Minimum permissions
|
|
|
|
These come from the Gitea and GitHub documentation and the API calls the
|
|
workflow makes. They have **not been confirmed with a minimal token on this
|
|
instance yet**; S05 should confirm them when the tokens are created.
|
|
|
|
**Gitea token** (a personal access token of a user, not a deploy key; deploy
|
|
keys do not work for the REST API):
|
|
|
|
- scope `read:repository`
|
|
- the user must be allowed to read the repository's push mirrors, which
|
|
Gitea limits to repository administrators
|
|
|
|
Calls made: `GET /repos/{owner}/{repo}` and `GET /repos/{owner}/{repo}/push_mirrors`.
|
|
|
|
**GitHub token** (fine-grained personal access token):
|
|
|
|
- Resource owner: the owner of the mirror repository
|
|
- Repository access: only the mirror repository
|
|
- Repository permission: **Administration: Read and write** (no other permission)
|
|
- Set an expiry date
|
|
|
|
Calls made: `GET /repos/{owner}/{repo}`, `PATCH /repos/{owner}/{repo}` (description)
|
|
and `PUT /repos/{owner}/{repo}/topics`.
|
|
|
|
Format of `CREDENTIALS_FOR_GITHUB`:
|
|
|
|
```json
|
|
{"GITHUB_PAT": "<token>"}
|
|
```
|
|
|
|
## What the workflow checks before it changes anything
|
|
|
|
The workflow runs a preflight and writes nothing to GitHub unless it passes:
|
|
|
|
1. Both secrets exist and have the expected shape.
|
|
2. Gitea accepts the token and the repository is visible with it.
|
|
3. At most one GitHub push mirror is configured. With none, the run ends
|
|
successfully without syncing and the GitHub secret is not read.
|
|
4. GitHub accepts the token for the mirror repository **and** the token
|
|
reports administration access to it.
|
|
|
|
On success the log says `Preflight passed: Gitea and GitHub accepted the
|
|
credentials.` Failures start with a category such as `[credentials]` or
|
|
`[permissions]`; see [troubleshooting.md](Troubleshooting). No secret value
|
|
is ever printed.
|
|
|
|
## Rotating a token
|
|
|
|
1. Create the new token with the permissions above.
|
|
2. Replace the secret value in the repository or organization settings.
|
|
3. Run the workflow manually and wait for `Preflight passed`.
|
|
4. Revoke the old token.
