description: "Use when a Gitea API merge on Dankclaw (192.168.0.143:3000) returns HTTP 422 \"[Do]: Required\" — the merge endpoint needs form-encoded fields with the lowercase field name do, not the JSON body that PR creation accepts."

Gitea on Dankclaw (192.168.0.143:3000) — merge quirk, measured 2026-10-19 on `dank/serverAppConfigs` and again on `dank/dankvoice`.
|
|
|
|
Creating a PR accepts a JSON body. **Merging does not**: `POST /api/v1/repos/{owner}/{repo}/pulls/{n}/merge` with a JSON body (`{"merge_style":"no-ff", ...}`) or with those values as request headers returns `422 {"message":"[Do]: Required"}` — four variants of that all fail identically, so do not "fix" it by changing the style name or moving the headers around.
|
|
|
|
**The field name is lowercase `do`.** `--data-urlencode 'Do=merge'` (capital D, which the error message spells) returns the same `422 [Do]: Required`. Do not retry with case variants — the web-UI form field is `do`.
|
|
|
|
Working call (form-encoded):
|
|
|
|
```bash
|
|
tok=$(sed -n 's|http://[^:]*:\([^@]*\)@.*|\1|p' ~/.config/secrets/gitea | head -1) # git credential.helper store file
|
|
curl -sS -X POST -w 'http %{http_code}\n' -K <(printf 'header = "Authorization: token %s"\n' "$tok") \
|
|
--data-urlencode 'do=merge' \
|
|
--data-urlencode 'merge_style=no-ff' \
|
|
http://192.168.0.143:3000/api/v1/repos/dank/<repo>/pulls/<N>/merge
|
|
# 200 with an empty body == merged
|
|
```
|
|
|
|
- `merge_style` values are the dashed names: `no-ff`, `merge`, `rebase`, `squash`.
|
|
- Keep the token out of argv: `-K <(printf …)` feeds the `Authorization` header through stdin (a `-H "Authorization: token …"` lands in `/proc/<pid>/cmdline`, world-readable — the 2026-09-16 HF-token leak class).
|
|
- Verify by fast-forwarding a checkout (`git fetch && git merge --ff-only origin/main`) rather than re-reading the PR.
|
|
- Fleet law still applies: never merge without an explicit current OK from Frank, and open the PR URL in his browser (`xdg-open`) the moment it exists.

## Credential-store token extraction (same file, adjacent trap)
|
|
|
|
`~/.config/secrets/gitea` holds one line shaped `http://user:token@192.168.0.143:3000`. Splitting it with `awk -F'/'` puts the host in `$3`, not `$2`, and `awk -F'/' '{print $NF}'` yields the host+path, not the token — an empty/garbage token makes **private repos answer `404 not found`** (Gitea hides them from anonymous), which reads like a wrong URL rather than an auth failure. Extract with:
|
|
|
|
```bash
|
|
tok=$(sed -n 's|^https\{0,1\}://[^:]*:\([^@]*\)@192\.168\.0\.143.*$|\1|p' ~/.config/secrets/gitea | head -1)
|
|
echo "token length: ${#tok}" # 40 — print the length, never the value
|
|
```
|
|
|
|
Other API quirks measured the same day:
|
|
|
|
- `GET /pulls?state=open` can return an error object where `state=all` returns the list; `state=all` list entries may omit `head`/`base` — fetch `/pulls/{n}` for those.
|
|
- POST `/pulls` for a head/base pair that already has a PR → `409` naming `issue_id: N`; the PR number is that `issue_id`, so PATCH it instead of POSTing again.
|
|
- Issues and PRs share the issue index per repo, so `#36`-style numbers are repo-scoped: a footer fix aimed at `dank/command-center#36` 404s when pointed at `dank/dankvoice`.
