Field report: a public channel that had accumulated 3800 messages made the
interface "slow down drastically", and clearing it restored normal speed. The
reporter also noticed it was still noticeable at only ~300 messages and asked
whether something loops over every message. It does.
threadHasMessageHistory() answered "does this thread have any stored message?"
by walking the ring via getThreadMessageIndexes(). That scan stops early once it
finds a match, so a thread WITH recent messages is cheap — but a thread with
none walks every record in the ring doing a strncmp per record, and "has no
history" is precisely what the callers are testing for. getCombinedInboxCount()
and getUnreadTotal() both call it once PER THREAD, so a full ring turned every
inbox refresh into threads x messages string compares. That is the reported
slowdown, and it explains why it is felt well below a full ring.
Now cached per thread:
- an append sets the owning thread's flag directly, so the common path never
scans at all;
- anything that REMOVES messages (ring eviction, clearThreadHistory,
removeThread, any history load) marks the cache dirty, and the next reader
rebuilds every thread's flag in ONE ring pass instead of one pass per
thread, stopping as soon as all live threads are resolved.
clearThreadHistory clears just its own flag (no other thread is touched), so the
common "clear one chat" action stays O(ring) once rather than forcing a rebuild.
Behaviour is unchanged; this only removes repeated work. The separate request
from the same thread — a configurable per-channel history limit with a lower
default and a warning — is NOT in this commit.
Builds clean on V4 + T-Deck; flashed to the T-Deck.

A real touchscreen UI for your mesh radio. · open source · GPL-3.0
Touch-UI MeshCore companion-radio firmware for the LilyGo T-Deck / T-Deck Plus and Heltec V4 + TFT (ESP32-S3).
An LVGL touch UI — map, chat, contacts, channels, settings — split out of
meshcomod. The app depends on a
MeshCore fork via PlatformIO lib_deps.

Architecture
This repo holds only the app: the companion_radio glue, the ui-touch
LVGL UI, the two boards' glue/variants, and platformio.ini. The MeshCore
core is not vendored here — it's pulled as a library via lib_deps from the
ALLFATHER-BV/meshcomod monorepo
(the same repo as the non-touch firmware), pinned by a lean source-only core-*
git tag. The touch-app files this repo owns (TouchPrefsStore, WifiRuntimeStore,
the transports, …) are dropped from the lib via -DMC_VENDORED_TOUCH_APP so they
aren't compiled twice. The build is byte-identical to the original in-tree
meshcomod firmware.
Build
PlatformIO pulls the core fork and all libraries automatically:
pio run -e heltec_v4_tft_companion_radio_usb_tcp_touch # Heltec V4 TFT
pio run -e LilyGo_TDeck_companion_radio_touch # LilyGo T-Deck
# or just `pio run` to build both
Flash with the NVS-preserving 4-component chain (bootloader / partitions /
boot_app0 / firmware at 0x0 / 0x8000 / 0xe000 / 0x10000) so saved Wi-Fi
credentials survive — not a merged image, which 0xFF-pads and wipes NVS.

License
GPL-3.0-or-later — see LICENSE. wadamesh is copyleft: anyone who distributes a build or a fork must also make their source available under the GPL. This keeps the UI open and concentrates community effort instead of fragmenting it into closed forks.
wadamesh incorporates and depends on MeshCore (MIT, © Scott Powell / rippleradios.com) and other third-party components — see NOTICE for the full list and their licenses. MeshCore-derived files keep their MIT notices; the combined work is distributed under the GPL (MIT is GPL-compatible). The MeshCore fork that wadamesh builds against stays MIT on purpose, so its Wi-Fi/BLE hooks remain upstreamable to MeshCore.
