Servers may allow the unauthenticated MCP handshake yet protect individual
tool calls via _meta["mcp/www_authenticate"]. The 'reauthorization is not
required' guard would silently abort the tool-challenge reauth path.
Threaded the authorization server's advertised registration endpoint through OAuth discovery, add, reauth, and the client flow instead of deriving metadata from the authorization endpoint.
Added pathful-issuer discovery and end-to-end DCR regression coverage.
Fixes#5267
Esc and wizard abort signals now race the MCP OAuth login promise directly, so cancellation wins even before OAuthCallbackFlow reaches its callback wait and registers an abort listener. OAuthCallbackFlow also checks pre-aborted signals before opening/waiting on the callback server and its wait path handles already-aborted signals.
Threaded the abort signal into MCP OAuth fetches so dynamic client registration, metadata discovery, authorization probes, and token exchange unblock promptly when the user cancels.
Added a regression test where MCPOAuthFlow.login never observes ctrl.signal, matching the pre-wait race called out in review.
Fixes#3888
#handleOAuthFlow now installs an editor.onEscape hook that aborts its
AbortController, and accepts an external abortSignal so the add-wizard
can thread its own controller through (the wizard owns focus and absorbs
Esc itself). Cancellation surfaces as MCPOAuthCancelledError, which the
reauth and add catches translate into a neutral status line instead of
the generic OAuth failure banner. Disambiguated from the existing 5-min
timeout via a userCancelled flag so timeouts still read as errors.
The wizard intercepts Esc/Ctrl+C while #oauthAbort is set so its own
"Press Esc to cancel" advertisement now matches the behaviour, and
renames its error heading + tip when the failure is a user cancel. Also
fixed the misleading "(Press Ctrl+C to cancel)" message in the chat
transcript onAuth block to say "Press Esc" — Ctrl+C is bound to the
editor clear action, not interrupt.
Fixes#3888
Migrate 203 test files (356 call sites) from fs.rm/fs.rmSync to
removeWithRetries/removeSyncWithRetries to reduce EBUSY test failures
on Windows. removeWithRetries is now exported from @oh-my-pi/pi-utils.
The migration uses a regex-based approach that:
- Replaces fs.rm(path, { recursive, force }) → removeWithRetries(path)
- Replaces fs.rmSync(path, { recursive, force }) → removeSyncWithRetries(path)
- Replaces fs.rm(path) → removeWithRetries(path) (no options)
- Skips fs.rm/fs.rmSync inside template literals (bun --eval scripts)
- Adds imports to existing @oh-my-pi/pi-utils import or creates new one
- Removes unused fs imports where fs.rm was the only fs usage (4 files)
