Merge Risk: 🔵 Low · up to Message history may fail to match or correctly label records if a connected node supplies a noncanonical ID. Confirm the device ID contract or normalize IDs when recording received messages. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to When logging is enabled, accepted message traffic can grow the history indefinitely and retain an expanding set of packet identifiers in memory. Sustained traffic could exhaust resources on the user's machine. Logging defaults off, and restrictive file permissions and escaped display text reduce other exposures. Retained concerns

Review comments at @meshtastic/__main__.py:
- Around line 607-612: Before calling message_store.log_sent in the sent-message
flow, normalize args.dest to the canonical node ID form used by _node_id,
preserving ^all, and pass the actual port used for the send so private messages
are recorded with their correct application.
- Around line 1659-1665: Update the message-argument flow in common() around
handleMessageStoreArgs and handleShowMessagesArgs: check for the --messages and
--show-messages combination before saving any setting, then return after on,
off, or status when no other command was given, using the same parser-default
comparison as handleShowMessagesArgs. Keep live running through the normal
command flow.
Review comments at @meshtastic/message_store.py:
- Around line 285-298: Update the my_id property logic so negative node numbers
from localNode.nodeNum are rejected before caching and the myInfo.my_node_num
fallback is tried; cache the formatted ID only when the selected value is a
non-negative integer.

Review comments at @meshtastic/message_store.py:
- Line 269: Update the message-log opening flow around os.open and
_tighten_permissions to reject symlink path components, use O_NOFOLLOW for the
final target where supported, and skip logging if validation or opening fails
before permissions are changed or records are written.
- Around line 76-77: Update the permission-tightening handler used by
MessageLog.append to let an os.fchmod OSError propagate to its existing error
handler instead of suppressing it, so the message is not appended when
permissions cannot be tightened.

absolute path without resolving symlinks, check the target and each parent for
symlinks, and raise `OSError` when one is found so the existing handler skips
the write.

Review comments at @meshtastic/__main__.py:

calling onConnected so the --sendtext path records the sender’s node ID; retain
the existing fallback when the sender ID is unavailable.

TCP setup when --messages is on, off, or status and every other parsed option
remains at its parser default. Preserve the existing connection path for live
mode and for invocations with any other non-default option.

data path, but leave paths supplied through `directory` or

`_ensure_dir` for all paths, including configured paths.

@ianmcorvidae Not sure if this acceptable? Im working on fine tuning it but I don’t know if this is something that is needed and if this is the right implementation. If you have any other way of implementation in mind, I can work on changes. Would appreciate the feedback! |

[optional] Persistent text-message log (
--messages,--show-messages)Refs [#593} (No way to get messages out via CLI)
Why
The library delivers received packets once over pubsub and keeps no history, so the CLI can't show messages after it exits. The README roadmap also lists a standardized way of recording packets for later use. This adds an opt-in, client-side text-message log and a way to read it back.
What this adds
--messages on|off|status|liveon/off: enable or disable logging and save the setting (default: off).status(also bare--messages): print whether logging is on, without changing it.live: log for this run only, without changing the saved setting. Combine it with--listen,--sendtext, etc.--show-messages [all]What gets logged (only while logging is enabled)
TEXT_MESSAGE_APPonly), captured frommeshtastic.receive.--sendtext, logged right after sending.How to use
