fix(telegram): retry on transient TLS failures during connect and send#1535
Merged
Conversation
Add exponential-backoff retry (3 attempts) around initialize() to handle transient TLS resets during gateway startup. Also catches TimedOut and OSError in addition to NetworkError. Add exponential-backoff retry (3 attempts) around send_message() for NetworkError during message delivery, wrapping the existing Markdown fallback logic. Both imports are guarded with try/except ImportError for test environments where telegram is mocked. Based on PR #1527 by cmd8. Closes #1526.

Connect retry
Wraps

Wraps the existing Markdown-fallback send logic with retry for
NetworkError— handles transient failures during message delivery without interfering with the Markdown → plain text fallback.Test safety
