fix: Telegram stream preview finalizes in place by obviyus · Pull Request #17218 · openclaw/openclaw

obviyus · 2026-02-15T14:39:51Z

Summary

switch Telegram stream preview transport from sendMessageDraft to sendMessage + editMessageText
finalize text-only replies by editing the same preview message in place (no extra final send)
keep fallback path for non-text/complex finals (normal delivery + preview cleanup)
fix race where a late in-flight preview update could overwrite the final formatted edit
decouple preview streaming from forced block-stream disable so Telegram block streaming still works when enabled
update Telegram streaming docs/config help text to match current behavior

Testing

pnpm test src/telegram/draft-stream.test.ts src/telegram/bot-message-dispatch.test.ts src/telegram/send.edit-message.test.ts src/telegram/bot-message.test.ts src/auto-reply/reply.block-streaming.test.ts
pnpm check

Greptile Summary

Switched Telegram stream preview transport from sendMessageDraft to sendMessage + editMessageText, enabling text-only final replies to be delivered by editing the same preview message in place instead of sending a duplicate final message.

Key changes:

Preview messages now use standard sendMessage API (no longer requires private chat with topics enabled)
Text-only finals edit the preview message in place (prevents duplicate sends)
Non-text/complex finals fall back to normal delivery with preview cleanup
Race condition fix: flush() now waits for all in-flight preview updates before returning, preventing late updates from overwriting the final formatted edit
Decoupled preview streaming from block streaming disable (Telegram block streaming works independently when enabled)
Updated docs and config help text to reflect new behavior

Confidence Score: 5/5

This PR is safe to merge with minimal risk
The changes are well-tested with comprehensive test coverage including race condition handling, fallback paths, and cleanup logic. The implementation correctly addresses the race condition by ensuring flush() waits for in-flight operations before returning. The finally block properly handles cleanup in both success and failure scenarios. Documentation and config help text accurately reflect the new behavior.
No files require special attention

Works well! To enable, we need a minimum of:

{
  "agents": {
    "defaults": {
      "blockStreamingDefault": "off"
    }
  },
  "channels": {
    "telegram": {
      "streamMode": "partial",
      "blockStreaming": false
    }
  }
}

Huge thanks to @amiller for the deep root-cause analysis in #7123 (and @rursache for the original request/demo). Switched from sendMessageDraft to edit-based streaming because draft bubbles are limited to specific DM/topic contexts and can conflict with block streaming, while sendMessage + editMessageText works consistently across Telegram contexts and lets us finalize in place. If Telegram later adds draft streaming support across all message contexts, we can reevaluate and move back to that path.

how to install it?

aflag · 2026-02-18T20:21:38Z

I believe that, after this change, openclaw will constantly edit the same message. It will write a full message, delete it all and come back with a new one. Is that the original intention? I'd rather either it sent the intermediate message or not show me at all. Seeing multiple messages popping up, not having any time to read, just to get a revised one is infuriating

obviyus · 2026-02-19T01:55:07Z

Hi, definitely not intentional. I believe this is fixed now, could you try running it on the latest commit?
