Closes #438

Part of didericis/bot-bottle-platform#1.

Summary

  • Adds bot_bottle/cli/login.py with a device-authorization flow against a bot-bottle console.
  • BB_CONSOLE_URL env var or --console-url flag sets the target; --label sets the host label (defaults to hostname).
  • On approval writes $BOT_BOTTLE_ROOT/console.json (mode 0600) with {url, host_id, access_token, refresh_token}.
  • login added to COMMANDS and NO_MIGRATION_COMMANDS (no local DB needed for auth).
  • 12 unit tests in tests/unit/test_cli_login.py.

Requesting changes for these issues:

  1. [P1] Remove the unrelated infrastructure-consolidation commit stack from this PR. This PR is described as adding bb login, but its branch is based on 44479f3 and also includes the full #431 Docker/Firecracker/macOS infrastructure refactor (6544c3f, 52c0df7, and follow-ups). Consequently, merging #437 would land 16 unrelated files and roughly 700 lines of backend/runtime changes alongside the login feature. Rebase/cherry-pick c9f2541 onto current main, or explicitly retarget this as a stacked PR after the infrastructure work has merged.

  2. [P1] Create the credentials file with mode 0600 before writing secrets. _save_credentials calls write_text() and only chmods afterward (bot_bottle/cli/login.py:72-86). For a new file, creation honors the process umask and will commonly produce mode 0644 until the later chmod; if the process is interrupted or the write/chmod fails, the access and refresh tokens remain readable by other local users. Overwriting an existing permissive file retains its old mode during the write as well. Write to an atomically-created 0600 temporary file in the same directory, fsync as appropriate, then os.replace it.

  3. [P2] Honor the server-provided polling interval. The authorization response includes poll_interval, but the client discards it and always sleeps _POLL_SLEEP (bot_bottle/cli/login.py:29,111-125). A console configured with a larger interval will be polled too aggressively and may rate-limit or reject the flow. Parse the returned interval (with sane bounds) and use it for polling.

Validation: the 12 login tests and 38 affected backend/lifecycle tests pass locally (50 total).

Rebased onto current main. The branch now contains only the single login commit (df249b6); the infrastructure commits have been dropped. PR body updated to reference Closes #438 (same-repo tracking issue) so the tracker policy passes.

Rereviewed current head 654fe13. The branch-scope issue is resolved: this PR now contains only the login change on current main, and the 12 login plus 13 dispatcher tests pass. The other two requested fixes are still absent, so I am keeping this at request changes.

Still blocking: The credentials are still written with path.write_text() before chmod(0600). A new file can therefore contain both tokens with umask-derived permissions (commonly 0644) until chmod completes, and interruption or chmod failure leaves it exposed; overwriting a permissive existing file also writes secrets while retaining that mode. Please atomically create a same-directory temporary file as 0600, write/flush it, then os.replace() the destination, and add a test that verifies the file is already private at write time/failure boundaries.

Still blocking: poll_interval remains discarded and every flow sleeps the hard-coded _POLL_SLEEP. The authorization response in the tests even supplies poll_interval but patches the module constant instead of verifying the contract. Please parse the server-provided interval with sane bounds/fallback, use it for each poll, and test that a non-default value reaches time.sleep().

Fixed in ec3791c. _save_credentials now creates a temp file via tempfile.mkstemp(dir=path.parent, prefix=".console-"), sets it explicitly to 0600, writes to it, then calls os.replace() to atomically move it to the final path. The token file never exists at console.json with any other permission mode, and an interruption leaves only a private temp file that is cleaned up in the except handler.

New test test_temp_file_is_private_before_replace spies on os.replace to verify the temp file is already 0600 at the moment of rename.

Fixed in ec3791c. poll_interval from the authorization response is now parsed and clamped to max(1, min(int(interval), 60)), falling back to _POLL_SLEEP when absent. The clamped value is stored as poll_sleep and passed to time.sleep() on every poll cycle.

New test test_poll_interval_from_server_is_used patches time.sleep and asserts every call receives the server-supplied value (7 s). Existing flow tests now patch time.sleep directly instead of the module constant.

Re-reviewed at 2915706. The earlier blockers are resolved: credentials are written via a mode-0600 same-directory temporary file and atomically replaced, and the bounded server-provided poll_interval is honored. The branch is scoped to the login feature, all current CI jobs pass, and I found no new blocking issues.

feat: add bb login command for console host registration 7ff3a0025e 
Starts a device-authorization flow against a bot-bottle console, polls
until the operator approves, then writes access + refresh tokens to
$BOT_BOTTLE_ROOT/console.json. Console URL is read from --console-url
flag or BB_CONSOLE_URL env var.

Part of didericis/bot-bottle-platform#1
fix(login): atomic credential write and respect server poll_interval 9b6788ebad 
Write credentials via a 0600 temp file + os.replace() so the token file
never appears at its final path with world-readable permissions, even if
the process is interrupted between write and chmod.

Parse poll_interval from the authorization response (clamped to 1–60 s,
falling back to _POLL_SLEEP) so aggressive polling can't trigger console
rate limits.

Tests: add atomicity spy asserting the temp file is 0600 before replace;
patch time.sleep instead of _POLL_SLEEP; add explicit interval-passthrough
assertion.

Replaces broad `except Exception` with specific types that reflect the
actual failure modes:
- _save_credentials: `except OSError` (IO-only path; re-raises for cleanup)
- _post error handler: `except (OSError, ValueError)` (network + bad JSON)
- poll-loop: `except (OSError, ValueError)` (network + bad JSON)

Also:
- Simplify _fake_get to use next(..., default) — removes uncovered
  StopIteration branch
- Add encoding="utf-8" to open() in test_approved_flow_returns_0
- Add test_cleanup_on_write_failure to cover the except OSError block
  in _save_credentials

`python -m bot_bottle.cli` failed with "is a package and cannot be
directly executed" — the package had a `if __name__ == "__main__"` block
in `__init__.py`, which never fires for a package and made the invocation
look supported when it wasn't. Add a real `__main__.py` and drop the dead
block.

Matters for `bb login`, whose docstring documents a `bb` entry point that
nothing installs; `-m` is the closest thing to it until there's a
console-script.

Approval now renders over the hosts page at /hosts/authorize?code=…
rather than on a standalone page. The console keeps /authorize as a
redirect, so this is cosmetic for older consoles.

Final review: approved. The CLI request/poll contract matches bot-bottle-console#21, credentials are written atomically with mode 0600, the new command bypasses the unrelated migration gate, and the module entry point is covered. Verified 22 focused login/entry-point tests pass. Merge after the console PR resolves its atomic authorization-state race.
