Wrap waitForCompactionRetry() in try/catch to capture AbortError
that was escaping and bypassing the model fallback mechanism.
When a timeout fires, session.abort() causes both session.prompt()
and waitForCompactionRetry() to throw AbortError. Previously only
the prompt error was captured, allowing the compaction error to
escape to model-fallback.ts where it was immediately re-thrown
(line 199: isAbortError check), bypassing fallback model attempts.
Fixes#313
This commit fixes several issues with multi-account OAuth rotation that
were causing slow responses and inefficient account cycling.
## Changes
### 1. Fix usageStats race condition (auth-profiles.ts)
The `markAuthProfileUsed`, `markAuthProfileCooldown`, `markAuthProfileGood`,
and `clearAuthProfileCooldown` functions were using a stale in-memory store
passed as a parameter. Long-running sessions would overwrite usageStats
updates from concurrent sessions when saving.
**Fix:** Re-read the store from disk before each update to get fresh
usageStats from other sessions, then merge the update.
### 2. Capture AbortError from waitForCompactionRetry (pi-embedded-runner.ts)
When a request timed out, `session.abort()` was called which throws an
`AbortError`. The code structure was:
```javascript
try {
await session.prompt(params.prompt);
} catch (err) {
promptError = err; // Catches AbortError here
}
await waitForCompactionRetry(); // But THIS also throws AbortError!
```
The second `AbortError` from `waitForCompactionRetry()` escaped and
bypassed the rotation/fallback logic entirely.
**Fix:** Wrap `waitForCompactionRetry()` in its own try/catch to capture
the error as `promptError`, enabling proper timeout handling.
Root cause analysis and fix proposed by @erikpr1994 in #313.
Fixes#313
### 3. Fail fast on 429 rate limits (pi-ai patch)
The pi-ai library was retrying 429 errors up to 3 times with exponential
backoff before throwing. This meant a rate-limited account would waste
30+ seconds retrying before our rotation code could try the next account.
**Fix:** Patch google-gemini-cli.js to:
- Throw immediately on first 429 (no retries)
- Not catch and retry 429 errors in the network error handler
This allows the caller to rotate to the next account instantly on rate limit.
Note: We submitted this fix upstream (https://github.com/badlogic/pi-mono/pull/504)
but it was closed without merging. Keeping as a local patch for now.
## Testing
With 6 Antigravity accounts configured:
- Accounts rotate properly based on lastUsed (round-robin)
- 429s trigger immediate rotation to next account
- usageStats persist correctly across concurrent sessions
- Cooldown tracking works as expected
## Before/After
**Before:** Multiple 429 retries on same account, 30-90s delays
**After:** Instant rotation on 429, responses in seconds
Discord voice messages have empty `content` with the audio in attachments.
The nullish coalescing operator (`??`) doesn't fall through on empty strings,
so voice messages were being dropped as 'empty content'.
Changed to logical OR (`||`) so empty string falls through to media placeholder.
Adds a /stop command that:
- Can interrupt a running agent session mid-execution
- Works in both DMs and group chats (including forum topics)
- Uses grammy's bot.command() to run before the main message handler
- Returns status: stopped, stop requested, or nothing running
Also fixes session key lookup in pi-embedded-runner to use sessionKey
instead of sessionId, ensuring /stop finds the correct active run.
