Two sites, same class, different blast radius:
`forge_http_base()` fell back to `http://localhost:3000` when
`HIVE_FORGE_URL` was unset. The NixOS module sets that variable
unconditionally, so the fallback could only ever fire for a process
started outside the module — where guessing produces a confusing
"connection refused" far from its cause. It now panics saying exactly
that.
`forge_git_url()` had a second, nastier fallback: a base URL with no
`://` produced `http://core:<token>@localhost:3000/...`, sending a
*credentialed* git push at whatever happened to answer on the local
port. Split the credential-insertion half out as `git_url_with_base`,
which panics on a malformed base.
That split also lets the tests cover the shape without setting a
process-wide env var, which would race every other test in the binary.
Adds a case pinning that the scheme is carried through rather than
assumed — the old hardcoded `http://` would have silently downgraded a
TLS-fronted forge.
Refs #2860
Rewrite the approval flow's step 4 as the three phases, with the reason
the rollback state is a git ref, and refresh the coordinator's node
inventory + dispatch table. Fix four doc comments that still pointed at
the deleted `run_merge_config_pr`.
Two hardening items from argus's review of #2374:
1. PR state check at submission:
- Add `pr_is_open(repo, pr)` to forge/pr_merge.rs using
`repo_get_pull_request` + `StateType` — early error if the PR is
already closed or merged instead of queuing a card that fails later
- Call it in `submit_merge_config_pr` before fetching the head sha
2. Atomic fetched_sha INSERT:
- Add `fetched_sha: Option<&str>` to `Approvals::submit_kind` so
the sha can be included in the INSERT rather than a follow-up UPDATE
- MergeConfigPr already knows the sha before inserting the row
(pr_head_sha runs first) → pass `Some(&sha)`, drop the separate
`set_fetched_sha` call → truly atomic
- ApplyCommit still needs two writes (sha resolved by git_fetch_to_tag
after the row exists) → pass `None`, `set_fetched_sha` unchanged
- All other callers (InitConfig, Spawn, UpdateMetaInputs,
SchedulePrompt) pass `None` — no behavioural change
- Add `fetched_sha_in_insert_is_readable_via_get` test covering the
MergeConfigPr path
Replace the hardcoded FORGE_HTTP const with forge_http_base() which
reads HIVE_FORGE_URL from the environment (already set unconditionally
by hive-c0re.nix to http://<forge.domain>). Add forge_git_url() helper
that inserts core:<token> credentials between scheme and authority for
git push/clone URLs.
All call sites updated:
- forge/mod.rs: api() OnceLock + new forge_git_url/forge_http_base fns
- forge/repos.rs: push_meta, push_config, ensure_meta_remote
- forge/pr_merge.rs: tokenised_repo_url delegate + test loosened
- workers/knowledge.rs: clone + push URLs
- socket_server/mod.rs: clone_url in RepoCreated response
No new env var: HIVE_FORGE_URL was already the right knob (mara).
Closes#1868. Closes#2174 (this supersedes the operators-team fix from
the closed#2218, which is re-applied in the ensure_operators_team call
that was already merged separately).
