| Cohort / File(s) | Summary |
|---|---|
Module core & update flow src/MoonBase/Module.h, src/MoonBase/Module.cpp |
Replace execOnUpdate/runInAppTask with postUpdate/getUpdate semaphores; UpdatedItem uses fixed-size Char; update(...) now takes originId; add processUpdatedItem callback and global gModulesDoc; loop()/begin() adjusted to new flow and semaphores. |
Shared routers & persistence src/MoonBase/SharedHttpEndpoint.h, src/MoonBase/SharedWebSocketServer.h, src/MoonBase/SharedEventEndpoint.h, src/MoonBase/SharedFSPersistence.h |
Add header-only SharedHttpEndpoint, SharedWebSocketServer, SharedEventEndpoint and SharedFSPersistence for per-module FS JSON, delayed-write queue, registerModule wiring, and centralized emit/sync logic. |
State updater / settings services lib/framework/StatefulService.h, lib/framework/*SettingsService.h, src/MoonBase/Modules/FileManager.h |
Propagate originId into JsonStateUpdater and many settings update(...) signatures (AP, MQTT, NTP, WiFi, Ethernet, Files); ETHERNET_SETTINGS_FILE path adjusted. |
Main app modularization src/main.cpp |
Add global std::vector<Module*> modules, create one-time shared router instances (HTTP/WS/Event), register modules centrally, unify begin/loop invocation and stack sizing adjustments. |
Event socket / emission buffering lib/framework/EventSocket.h, lib/framework/EventSocket.cpp |
New emitEvent(const JsonDocument&) overload; make emitEvent signatures const-correct; replace per-call heap buffers with static buffers/vectors to reduce heap allocations. |
FS persistence & FileManager integration src/MoonBase/SharedFSPersistence.h, src/MoonBase/Modules/FileManager.h, src/MoonBase/Modules/FileManager.cpp |
New SharedFSPersistence class (registerModule, read/write per-module JSON, delayed writes); FilesState::update gains originId; FileManager.begin starts WebSocket in sequence. |
Heap/stack notes & build flags lib/framework/EventEndpoint.h, lib/framework/HttpEndpoint.h, lib/framework/WebSocketServer.h, src/MoonLight/Layers/PhysicalLayer.cpp, firmware/*.ini, lib/framework/ESP32SvelteKit.cpp |
Add PSRAM/heap optimization comments across headers; adjust some layer defaults; increase HTTPD and loop-task stack sizes via build flags and task creation. |
Utilities & Char type improvements src/MoonBase/Utilities.h, src/MoonBase/Utilities.cpp |
Remove runInAppTask globals; add const-correct Coord3D converters, Char constructors/assignments/operators and helpers; add fastDiv255. |
Nodes / Drivers / Effects signatures & fixes src/MoonBase/Nodes.h, src/MoonBase/Nodes.cpp, src/MoonLight/Nodes/Drivers/*, src/MoonLight/Nodes/Effects/* |
Wide signature tightening: String& → const Char<20>&, JsonObject const-correctness; fix =→== bugs; use WiFi OR ETH connectivity checks; initialization/memset/memcpy fixes. |
Module subclasses lifecycle & onUpdate changes src/MoonBase/Modules/*, src/MoonLight/Modules/* |
Many modules: setupDefinition now const JsonArray&, onUpdate takes const UpdatedItem&, many begin()/loop() marked override; some modules add local queuing (e.g., ModuleIO newBoardID) and change "null" checks to "". |
System status & heap diagnostics lib/framework/SystemStatus.h, lib/framework/SystemStatus.cpp, interface/src/* |
Add SystemStatus::heapHealth to report app/DMA heap diagnostics; frontend types/UI updated to display heap_info_app and heap_info_dma; proxy target changed in vite config. |
Shared endpoint header comments lib/framework/EventEndpoint.h, lib/framework/HttpEndpoint.h, lib/framework/WebSocketServer.h |
Add heap/PSRAM commentary blocks above endpoint classes; no control-flow changes. |
Misc: logging, config, docs & build lib/PsychicHttp/src/PsychicHttpServer.cpp, platformio.ini, firmware/*.ini, docs/*, interface/*, .coderabbit.yaml |
Improve endpoint error logging, bump APP_DATE, remove deprecated envs, docs updated for new signatures, UI tweaks, proxy host update, and minor formatting changes. |

Estimated code review effort
🎯 4 (Complex) | ⏱️ ~60 minutes
- Files/areas needing extra attention:
- src/MoonBase/Module.{h,cpp}: semaphore producer/consumer correctness, UpdatedItem lifetimes and thread-safety.
- src/MoonBase/SharedFSPersistence.h: delayed-write queue semantics, file/dir creation, concurrent read/write and update handler registration.
- Shared endpoints: originId propagation, registration/unregistration races and per-client state handling.
- Global gModulesDoc allocation/cleanup and JSON lifetime across tasks.
- EventSocket static buffers and MsgPack path concurrency.
- Widespread signature changes: ensure all callers updated to new update(..., originId) signatures.
Possibly related PRs
- Module: support button, new rows, nested tables #1 — touches module update plumbing and UpdatedItem/onUpdate handling; likely related changes to update flow and signatures.
Suggested labels
enhancement
"I hopped through bytes and trimmed the heap,
I queued the updates, not too deep,
Routers now share, semaphores hum,
Files saved slow — the burrow's done,
Nibble a carrot, code takes a leap."

@CodeRabbit-ai to be more specific: Module.h defines class variables which are template classess: HttpEndpoint _httpEndpoint; // sizeof() = 152 And sizeof(Module) = 1144 Plus each of these template classes also might do things on the heap. So I think this might not be the best setup in terms of minimizing heap use. @CodeRabbit-ai, can you review this, check heap usage of these template classes and propose changes to do this in more heap-optimal way? |

Tip For best results, initiate chat on the files or code changes. 🧩 Analysis chain🏁 Script executed: Length of output: 26546 @MoonModules, excellent question! I've analyzed the template classes and their heap usage. Here's what I found: Current Heap Usage AnalysisPer Module (×15 modules):
Total Heap Impact (15 modules):
Biggest Memory Consumer: Proposed Optimizations1. Replace String with const char (Quick Win)*Since paths are typically static strings, eliminate heap allocations: // In HttpEndpoint.h
class HttpEndpoint {
protected:
// String _servicePath; // OLD: heap allocation
const char* _servicePath; // NEW: no heap allocation
public:
HttpEndpoint(..., const char *servicePath, ...)
: _servicePath(servicePath) { }
};
// Similar changes for EventEndpoint, WebSocketServer, FSPersistenceSavings: ~80 bytes heap per module × 15 = 1,200 bytes 2. Pointer-Based Lazy Initialization (Medium Impact)Only allocate components when needed: // In Module.h
class Module : public StatefulService<ModuleState> {
private:
HttpEndpoint<ModuleState>* _httpEndpoint = nullptr;
EventEndpoint<ModuleState>* _eventEndpoint = nullptr;
WebSocketServer<ModuleState>* _webSocketServer = nullptr;
FSPersistence<ModuleState>* _fsPersistence = nullptr;
public:
Module(...) {
// Allocate in constructor or begin()
_httpEndpoint = new HttpEndpoint<ModuleState>(...);
_eventEndpoint = new EventEndpoint<ModuleState>(...);
_webSocketServer = new WebSocketServer<ModuleState>(...);
_fsPersistence = new FSPersistence<ModuleState>(...);
}
~Module() {
delete _httpEndpoint;
delete _eventEndpoint;
delete _webSocketServer;
delete _fsPersistence;
}
};Savings: Moves 880 bytes per module from global memory to heap (controlled allocation timing) 3. Shared WebSocketServer (Biggest Win)Use a single WebSocketServer with multiplexing: // In a shared location
class SharedWebSocketServer {
private:
PsychicWebSocketHandler _webSocket;
std::map<String, StatefulService<ModuleState>*> _modules;
public:
void registerModule(const char* moduleName, StatefulService<ModuleState>* service) {
_modules[moduleName] = service;
}
void transmitData(const char* moduleName) {
auto it = _modules.find(moduleName);
if (it != _modules.end()) {
// Send data for specific module
}
}
};
// In Module.h - remove WebSocketServer member
class Module {
private:
// WebSocketServer<ModuleState> _webSocketServer; // REMOVED
static SharedWebSocketServer* _sharedWS; // Shared across all modules
};Savings: (488 bytes × 14) + heap buffers = ~6,832 bytes + significant heap 4. JsonDocument PoolingReuse JsonDocument instances instead of creating temporary ones: // In WebSocketServer.h
template <class T>
class WebSocketServer {
private:
static JsonDocument _sharedJsonDoc; // Shared across instances
void transmitData(PsychicWebSocketClient *client, const String &originId) {
// Reuse _sharedJsonDoc instead of creating new JsonDocument
_sharedJsonDoc.clear();
JsonObject root = _sharedJsonDoc.to<JsonObject>();
_statefulService->read(root, _stateReader);
String buffer;
serializeJson(_sharedJsonDoc, buffer);
// ... send
}
};Savings: Eliminates temporary allocations, saves ~500-1000 bytes per transmit operation 5. Recommended Implementation PlanPhase 1 (Easy, Low Risk):
Phase 2 (Medium Impact): Phase 3 (High Impact, Higher Complexity): Expected Total Savings
Total potential savings: ~8,000-10,000 bytes which increases your effective heap from 60KB to ~70KB. Would you like me to generate the complete code changes for Phase 1 (the quick wins)? |
@CodeRabbit-ai, yeah - why not - go ahead |

src/MoonBase/Module.cpp (1)
333-378: Module::begin now calls Http/Event endpoint begin() twice – likely unintended and wastes heapThe new heap‑measurement block is helpful, but it also introduces duplicate
begin()calls:size_t heapBefore = ESP.getFreeHeap(); _httpEndpoint.begin(); Serial.printf(...); heapBefore = ESP.getFreeHeap(); _eventEndpoint.begin(); Serial.printf(...); heapBefore = ESP.getFreeHeap(); _webSocketServer.begin(); Serial.printf(...); EXT_LOGV(MB_TAG, ""); _httpEndpoint.begin(); // ← second call _eventEndpoint.begin(); // ← second call _fsPersistence.readFromFS();Calling
_httpEndpoint.begin()and_eventEndpoint.begin()twice can:
- Register the same routes/handlers twice, depending on PsychicHttpServer semantics.
- Allocate underlying resources twice, which is counter to the heap‑optimization goal.
You likely only want a single
begin()per endpoint. A minimal fix:void Module::begin() { - size_t heapBefore = ESP.getFreeHeap(); - - _httpEndpoint.begin(); - Serial.printf("%s HttpEndpoint used: %d bytes\n", - _moduleName.c_str(), - heapBefore - ESP.getFreeHeap()); - heapBefore = ESP.getFreeHeap(); - - _eventEndpoint.begin(); - Serial.printf("%s EventEndpoint used: %d bytes\n", - _moduleName.c_str(), - heapBefore - ESP.getFreeHeap()); - heapBefore = ESP.getFreeHeap(); - - _webSocketServer.begin(); // ← This probably uses the most - Serial.printf("%s WebSocketServer used: %d bytes\n", - _moduleName.c_str(), - heapBefore - ESP.getFreeHeap()); - - EXT_LOGV(MB_TAG, ""); - _httpEndpoint.begin(); - _eventEndpoint.begin(); + size_t heapBefore = ESP.getFreeHeap(); + + _httpEndpoint.begin(); + Serial.printf("%s HttpEndpoint used: %u bytes\n", + _moduleName.c_str(), + (unsigned)(heapBefore - ESP.getFreeHeap())); + + heapBefore = ESP.getFreeHeap(); + _eventEndpoint.begin(); + Serial.printf("%s EventEndpoint used: %u bytes\n", + _moduleName.c_str(), + (unsigned)(heapBefore - ESP.getFreeHeap())); + + heapBefore = ESP.getFreeHeap(); + _webSocketServer.begin(); // likely largest consumer + Serial.printf("%s WebSocketServer used: %u bytes\n", + _moduleName.c_str(), + (unsigned)(heapBefore - ESP.getFreeHeap())); + + EXT_LOGV(MB_TAG, ""); _fsPersistence.readFromFS(); updateOriginId = _moduleName + "server"; ...(Using
%u+ cast is optional but avoids signed/unsigned mismatch withsize_t.)
🧹 Nitpick comments (6)
src/MoonBase/Utilities.cpp (1)
166-170: Global runInAppTask queue is unbounded and may fragment heapThe
runInAppTaskvector is a globalstd::vector<std::function<void()>>that can grow without bound. Even thoughdriverTaskswaps it into a local vector and destroys it each loop, a burst of enqueued tasks will still allocate multiplestd::functionobjects and backing storage, which can fragment the limited ESP32 heap.Consider:
- Adding a simple upper bound (e.g., drop or log when
runInAppTask.size()exceeds a safe threshold).- Optionally
reserve()‑ing a small fixed capacity at startup to avoid repeated growth/shrink cycles.- If you want more control/tracking, wiring this through your
VectorRAMAllocatorwould also make the memory source more explicit.src/main.cpp (1)
86-89: Heap-optimization comments are useful but may drift over timeThese comments give good context on per-module memory usage and constraints. Just be aware they can get stale as modules evolve; consider keeping them in sync with automated
sizeof/heap instrumentation (e.g., tests you already have) rather than relying on manual updates.src/MoonBase/Utilities.h (1)
383-387: Header now exposes std::vector/std::mutex but doesn’t include their headersThese externs introduce
std::vector<std::function<void()>>andstd::mutexin the public header, but the header itself doesn’t include<vector>,<functional>, or<mutex>. This works only as long as every translation unit includingUtilities.hhappens to pull those in transitively.To make this header self‑contained and less fragile, I’d add the standard headers here:
#include <Arduino.h> #include <ESPFS.h> #include "ArduinoJson.h" + #include <vector> + #include <functional> + #include <mutex>(Alternatively, add them to a central common header if that’s your pattern.)
Also, for clarity, you may want to use the same guard macro here as at the call sites (e.g.,
#if FT_ENABLED(FT_MOONLIGHT)), though that’s optional as long as the compile‑time definitions line up.src/MoonBase/Module.cpp (3)
106-115: Async onReOrderSwap queuing looks correct but capture could be more explicitRouting
onReOrderSwapthroughrunInAppTaskunderFT_ENABLED(FT_MOONLIGHT)is a good way to move the heavier re‑mapping work off the HTTP server stack. The lambda:runInAppTask.push_back([&, stateIndex, newIndex]() { onReOrderSwap(stateIndex, newIndex); });implicitly captures
thisby reference via[&], which is safe here becauseModuleState/Moduleare long‑lived. However, it also risks accidentally capturing future locals by reference.For clarity and to make lifetime assumptions explicit, I’d suggest:
- runInAppTask.push_back([&, stateIndex, newIndex]() { onReOrderSwap(stateIndex, newIndex); }); + runInAppTask.push_back([this, stateIndex, newIndex]() { + onReOrderSwap(stateIndex, newIndex); + });This keeps the heap profile the same but reduces the chance of subtle captures if this block is edited later.
138-148: execOnUpdate async path copies UpdatedItem; comment/capture can be tightenedOffloading
onUpdateviarunInAppTaskis the right move to protect the HTTP task’s stack, but a couple of details are worth tightening:runInAppTask.push_back([&, updatedItem]() mutable { // mutable as updatedItem is called by reference (&) onUpdate(updatedItem); });
updatedItemis actually captured by value here (good, because the original goes out of scope afterexecOnUpdatereturns). The comment suggesting “called by reference” is misleading.- The lambda doesn’t modify
updatedItem, somutableis unnecessary.- Capturing everything else by reference via
[&]implicitly drags inthis; making that explicit is clearer.You can simplify to:
- runInAppTask.push_back([&, updatedItem]() mutable { - onUpdate(updatedItem); - }); + runInAppTask.push_back([this, updatedItem]() { + onUpdate(updatedItem); + });This preserves semantics (including the necessary copy of
UpdatedItem) while slightly reducing capture scope and avoiding confusion about value vs reference.
386-389: Duplicate heap-optimization comment block – consider consolidatingThis heap-optimization comment near
setupDefinitionlargely repeats the earlier block above theModuleconstructor. It’s harmless, but having the same note in multiple places increases the chance they’ll diverge over time.Consider keeping a single, well‑maintained comment (or moving this information into a short design note) to reduce duplication.

36-36: Clarify whether this is a breaking change or a new path definition.This path change has no impact on heap usage (both are compile-time constants) and appears unrelated to the PR's stated heap optimization objectives.
However, the critical discovery is that
FSPersistence.mkdirs()automatically creates missing parent directories, so the new/.config/directory will be created on first save. This prevents the "directory doesn't exist" failure.The remaining concern: The search found zero references to
/config/ethernetSettings.jsonanywhere in the codebase, yet the review assumes this was the previous path. Either:
- This is a new path definition (not a modification), or
- The old path references were already removed before this PR
Please clarify:
- Is this a modification of existing code or a new definition?
- If users have existing settings at the old path, should they be migrated?
- Why was this path changed as part of a heap-optimization PR?

89-90: Verify 6 KB HTTPD stack size against worst‑case usageSetting
HTTPD_STACK_SIZE=6144for the MoonBase-only envs makes sense to give the HTTP server more headroom, but it also eats into limited internal RAM on PSRAM‑less boards.I’d recommend verifying on real hardware that:
- The HTTP server task’s
uxTaskGetStackHighWaterMarkstays comfortably above zero under worst‑case requests (large JSON, many modules).- You’re not over‑provisioning compared to what’s actually needed now that heavy work is offloaded via
runInAppTask.Also applies to: 107-108

295-313: Rebalanced effect/driver task stack sizes – confirm high‑water marksYou’ve shifted 1 KB of stack from
AppEffectTasktoAppDriverTaskon non‑PSRAM boards:
AppEffectTask:(psramFound() ? 6 : 3) * 1024AppDriverTask:(psramFound() ? 6 : 4) * 1024Given that
driverTasknow also drainsrunInAppTaskand may execute arbitrary lambdas, the larger driver stack is reasonable, but the reduced effect stack (3 KB) is tight on ESP32.Please verify on real hardware that both tasks still have safe

45-84: Undefinednameidentifier and opportunity for safer, allocation‑free comparisonInside both
effectsanddriversloops,nameis no longer defined, but still used in the final log lines (Lines 62 and 81). This will fail to compile. At the same time, you can avoid temporaryStringallocations fromJsonVariantby extracting aconst char*once per node and reusing it.Consider something along these lines:
- _moduleEffects->read([&](ModuleState& effectsState) { - for (JsonObject nodeState : effectsState.data["nodes"].as<JsonArray>()) { - - if (updatedItem == nodeState["name"]) { + _moduleEffects->read([&](ModuleState& effectsState) { + for (JsonObject nodeState : effectsState.data["nodes"].as<JsonArray>()) { + const char* nodeName = nodeState["name"].as<const char*>(); + if (nodeName && updatedItem == nodeName) { EXT_LOGV(ML_TAG, "updateHandler equals current item -> livescript compile %s", updatedItem.c_str()); LiveScriptNode* liveScriptNode = (LiveScriptNode*)_moduleEffects->findLiveScriptNode(nodeState["name"]); if (liveScriptNode) { liveScriptNode->compileAndRun(); _moduleEffects->requestUIUpdate = true; // update the Effects UI } - - EXT_LOGV(ML_TAG, "update due to new node %s done", name.c_str()); + EXT_LOGV(ML_TAG, "update due to new node %s done", nodeName); } index++; } }); - _moduleDrivers->read([&](ModuleState& effectsState) { - for (JsonObject nodeState : effectsState.data["nodes"].as<JsonArray>()) { - - if (updatedItem == nodeState["name"]) { + _moduleDrivers->read([&](ModuleState& effectsState) { + for (JsonObject nodeState : effectsState.data["nodes"].as<JsonArray>()) { + const char* nodeName = nodeState["name"].as<const char*>(); + if (nodeName && updatedItem == nodeName) { EXT_LOGV(ML_TAG, "updateHandler equals current item -> livescript compile %s", updatedItem.c_str()); LiveScriptNode* liveScriptNode = (LiveScriptNode*)_moduleDrivers->findLiveScriptNode(nodeState["name"]); if (liveScriptNode) { liveScriptNode->compileAndRun(); _moduleDrivers->requestUIUpdate = true; // update the Effects UI } - - EXT_LOGV(ML_TAG, "update due to new node %s done", name.c_str()); + EXT_LOGV(ML_TAG, "update due to new node %s done", nodeName); } index++; } });This both fixes the missing identifier and avoids constructing a temporary

int indexin the loop at line 37 is confirmed undefined behavior:for (int index; index < layer->nrOfLights; index++)The variable has an indeterminate starting value, causing unpredictable loop behavior (may not run, iterate incorrectly, or access out of bounds).

138-149: Same lifetime concern applies here.This suffers from the same issue as the
onReOrderSwaplambda: capturingthisby reference (&) can lead to dangling references if the Module is destroyed before task execution.Additionally, the comment "mutable as updatedItem is called by reference (&)" is slightly misleading—
mutableallows modification of the captured copy, butonUpdatereceives the updatedItem by reference, which is valid.

126-195: onUpdate signature matches new Node APIUpdating the handler to
onUpdate(Char<16>& oldValue, JsonObject control) overridekeeps this driver consistent with the rest of the node system. The body doesn’t useoldValue, but that’s harmless and keeps the override compatible.You could mark
oldValueunused (e.g.Char<16>& /*oldValue*/) to silence potential warnings.src/MoonLight/Nodes/Effects/E__Sandbox.h (1)
35-39: Template onUpdate fix is good; consider restoringoverride
- Changing to
Char<16>& oldValueand fixingif (control["value"] == 0)correctly aligns the example with the new Node API and fixes the prior assignment bug.- To keep compile‑time checking consistent with other nodes, it would be better to declare this as
void onUpdate(Char<16>& oldValue, JsonObject control) override.- Since
oldValueisn’t used, you can also mark it unused (e.g./*oldValue*/) if warnings are an issue.src/MoonBase/NodeManager.h (1)
23-24: Char<16> migration here is fine; just confirm max lengthsChanging
defaultNodeNameandUpdatedItem.oldValue/parent/name(used here) toChar<16>reduces heap pressure and works with the updatedNode::updateControl/onUpdateAPIs, but it does cap stored strings at 15 characters. That seems safe for current identifiers like"nodes","controls","name","on", and typical short node names, yet will truncate longer filenames or control values if you ever rely on the full text in logs or logic.Given this is central infrastructure, it’s worth double‑checking:
- Expected maximum node file name and control name lengths.
- Whether any downstream comparisons (e.g., against longer path strings) could silently fail due to truncation.
The updated logs using
as<const char*>()fornodeState["name"]are a nice win to avoid extra temporaryStringallocations.Also applies to: 98-100, 248-249, 255-256, 260-262, 271-272
src/MoonBase/Module.h (1)
27-33: UpdatedItem and updateOriginId Char<16> choices: check expected max lengthsSwitching
UpdatedItem::parent[2],name,oldValue, andModule::updateOriginIdtoChar<16>is a big win against heap churn, but it hard‑caps each at 15 visible characters. For current usage (keys like"nodes","controls","name","lightPreset","number of Particles", short origin IDs), this is probably fine, but it will silently truncate longer values.Before this spreads further, it’s worth validating:
- Typical and worst‑case lengths for:
- JSON parent path segments (
parent[0],parent[1])- Control names and module names stored in
name- Any logic that compares
oldValuetextually (beyond checking for""/"null")updateOriginIdcontents- Whether any external integrations rely on full filenames or IDs longer than 15 chars.
If you expect longer names or IDs, bumping some of these to
Char<32>(especiallyoldValueandupdateOriginId) would still keep heap usage controlled while avoiding unexpected truncation.Also applies to: 124-125
src/MoonBase/Nodes.h (1)
144-146: Consider simplifying the initialization pattern.The two-step initialization can be simplified to a single line for better readability:
Apply this diff:
- Char<16> oldValue; - oldValue = ""; + Char<16> oldValue = "";Note: Verify that 16 bytes is sufficient for all potential
oldValuecontent. If longer values are expected, consider increasing the buffer size to prevent truncation.src/MoonBase/Module.cpp (1)
310-316: Be aware of per-Module WebSocketServer memory footprint.As noted in the PR objectives, each Module now instantiates its own WebSocketServer (488 bytes each × 15 modules = ~7KB). The String concatenations in the initializer list create temporary String objects that allocate heap memory.
Consider the following for future optimization (Phase 2/3 as mentioned in PR):
- Use string literals or pre-constructed paths where possible
- Share a single WebSocketServer with multiplexing (Phase 3)
- Convert member objects to pointers with lazy allocation (Phase 2)

154-154: LGTM! Consistent migration to fixed-size buffers.The migration from

172-173: Appropriate handling of mixed JsonVariant types.The
.as<String>().c_str()approach correctly handles non-string JsonVariant values by converting them to strings first. While this ensures consistent behavior, be aware that this conversion adds overhead for numeric types.
179-182: Good addition for String compatibility.The new
operator=(const String&)improves API completeness and allows direct assignment from Arduino String objects without requiring explicit.c_str()calls.
189-189: Excellent const-correctness improvements.Adding

131-131: Cleaner string comparison using Char API.The use of
.contains()is more readable than explicitc_str()calls and leverages the Char template's API appropriately.
167-167: Proper JsonString to Char assignments.The assignments from JsonString to Char<16> fields leverage the appropriate operator overloads defined in the Char template. These conversions are handled correctly.
Also applies to: 208-209, 213-214, 256-259
336-340: Proper initialization sequence.The initialization order is appropriate: endpoints are started before reading from the filesystem, ensuring all communication channels are ready before loading persisted state.
107-116: Verify the architectural assumption that all Module instances are long-lived and never dynamically destroyed.The lambda in Module.cpp:111 captures
thisby reference. While current code shows all Module instances are global and should outlive task execution, this is an architectural assumption not enforced by the code itself.To confirm this is safe:
- Verify that Module instances (and derived classes like ModuleEffects, ModuleDrivers, etc.) are never dynamically allocated with
newormake_shared- Confirm no module pooling/recycling or hot-reloading exists
- Ensure no shutdown sequence destroys modules before
runInAppTaskdrainsIf Module instances could be dynamically allocated or destroyed, consider refactoring to capture a
shared_ptror implementing explicit task draining in the Module destructor.

There was a problem hiding this comment.
Guard against null scriptState["name"] when logging
scriptState["name"].as<const char*>() may legitimately return nullptr if the field is missing or not a string. Passing a null pointer to a %s format in EXT_LOGW is undefined and can crash.
Recommend extracting and guarding the name:
- } else
- EXT_LOGW(ML_TAG, "liveScriptNode not found %s", scriptState["name"].as<const char*>());
+ } else {
+ const char* scriptName = scriptState["name"].as<const char*>();
+ EXT_LOGW(ML_TAG, "liveScriptNode not found %s", scriptName ? scriptName : "<null>");
+ }This keeps heap usage low while avoiding undefined behavior when the name is absent or invalid.

const char*name with a safe fallback (e.g."<unnamed>") and reuse it for logging, rather than callingnodeState["name"].as<const char *>()inline in each log site.Example (effects loop sketch):
- _moduleEffects->read([&](ModuleState& effectsState) { - for (JsonObject nodeState : effectsState.data["nodes"].as<JsonArray>()) { - - if (updatedItem == nodeState["name"]) { + _moduleEffects->read([&](ModuleState& effectsState) { + for (JsonObject nodeState : effectsState.data["nodes"].as<JsonArray>()) { + const char* nodeName = nodeState["name"].as<const char*>(); + if (nodeName && updatedItem == nodeName) { EXT_LOGD(ML_TAG, "updateHandler equals current item -> livescript compile %s", updatedItem.c_str()); LiveScriptNode* liveScriptNode = (LiveScriptNode*)_moduleEffects->findLiveScriptNode(nodeState["name"]); if (liveScriptNode) { liveScriptNode->compileAndRun(); _moduleEffects->requestUIUpdate = true; // update the Effects UI } - EXT_LOGD(ML_TAG, "update due to new node %s done", nodeState["name"].as<const char *>()); + EXT_LOGD(ML_TAG, "update due to new node %s done", nodeName); }Same idea can be mirrored in the drivers loop.

167-182: Char assignment from JsonVariant still allocates; consider usingas<const char*>()to cut heap churn
Char& operator=(const JsonVariant rhs)currently does:if (!rhs.isNull()) strlcpy(s, rhs.as<String>().c_str(), sizeof(s));This builds a temporary
Stringon the heap each time. Given this PR’s heap focus, consider:Char& operator=(const JsonVariant rhs) { - if (!rhs.isNull()) strlcpy(s, rhs.as<String>().c_str(), sizeof(s)); + if (!rhs.isNull()) { + const char* v = rhs.as<const char*>(); + if (v) strlcpy(s, v, sizeof(s)); + else s[0] = '\0'; + } else { + s[0] = '\0'; + } return *this; }This avoids a transient

23-24: SwitchingdefaultNodeNametoChar<16>is safe here
defaultNodeNamenow usesChar<16>, and it’s only written via its implicit default ("") and read viadefaultNodeName.c_str()for JSON defaults. For typical node script filenames this should be sufficient and saves aStringinstance perNodeManager.

132-282: Node controls invalidation/removal and new constUpdatedItem&flow look correct
onUpdate(const UpdatedItem& updatedItem)matches the new module API, and allupdatedItemusage is read‑only.The “invalidate controls” step:
if (nodeState["controls"].isNull()) { nodeState["controls"].to<JsonArray>(); } else { for (JsonObject control : nodeState["controls"].as<JsonArray>()) { control["valid"] = false; } }combined with the backwards removal loop removes only controls left with
valid == false, which is correct and avoids index-shift issues.The backwards loop is safe even when
controls.size() == 0becauseint i = size - 1;becomes-1and the loop body is skipped.Calls to
nodeClass->updateControl(updatedItem.oldValue, ...)andnodeClass->onUpdate(updatedItem.oldValue, ...)now propagate theChar<16>oldValue into drivers as intended.Overall the refactor maintains previous behavior while aligning with the new Char/const conventions.

EXT_LOGE(ML_TAG, "type of %s not compatible: %s (%d)", control["name"].as<const char*>(), control["type"].as<const char*>(), control["size"].as<uint8_t>());which avoids constructing temporary
Strings and is more heap‑friendly.For new controls, creating a local
Char<16> oldValue;(implicitly empty) and passing it intoupdateControl/onUpdatematches prior semantics where oldValue is “no previous value”. For first‑time setup this is sufficient and bounded in size.No correctness issues detected here.

27-33: Well-designed heap optimization with fixed-size strings.The change from
StringtoChar<16>forparent,name, andoldValueis an effective heap optimization that reduces theUpdatedItemstruct size from 160 to ~68 bytes while keeping it stack-allocated.

338-338: Review WebSocketServer initialization ordering before readFromFS() to prevent race conditions.The concern is valid: WebSocketServer::begin() only sets up event handlers and registers the WebSocket handler on the server, but does not transmit state. However, when a client connects, onWSOpen() calls transmitData() to send the current state.
The current ordering in Module::begin() (lines 336-339) calls
_webSocketServer.begin()before_fsPersistence.readFromFS(), creating a narrow window where a WebSocket client could connect and receive uninitialized state instead of persisted state.While the practical risk is low (clients don't auto-connect; the window exists only during startup), this should be reordered for safety: move
_fsPersistence.readFromFS()to execute before_webSocketServer.begin()to ensure all state is loaded before the WebSocket server is ready to accept connections.
109-117: Remove lifetime safety review concern — Module instances are global static objects with program-wide lifetime.The original review raises concerns about
thispointer lifetime and suggests usingstd::weak_ptror ref-counting. However, this concern does not apply to the actual codebase.All Module instances (
moduleDevices,moduleTasks,moduleIO, etc.) are global static objects declared in main.cpp (lines 97-100), not dynamically allocated. They are initialized at program startup and persist for the entire device runtime. ThedriverTaskFreeRTOS loop continuously processes queued callbacks, ensuring that when any lambda executes, the Module instance that capturedthisis still valid. No lifetime safety issue exists, and no refactoring with smart pointers is necessary.Likely an incorrect or invalid review comment.

127-127: I need to trace the possible values forupdateOriginIdmore carefully. Let me search for_moduleNamevalues and verify the actual origin ID usage patterns.Now let me search for the _moduleName initialization and actual values used:
I need to search the codebase more thoroughly for _moduleName values and the actual contents being assigned to updateOriginId. Let me look for module names and initialization:
Based on my analysis of the shell script output and the code context, I can now make a determination. The shell output shows two specific assignment paths:
- Line 341 (Module.cpp):
updateOriginId = _moduleName + "server";- Line 367 (Module.cpp):
updateOriginId = originId;(receives from parameter)The second assignment (line 367) is the critical risk point. It directly assigns the
originIdparameter received from framework update handlers without any validation. From the shell search results, I can see thatoriginIdis aconst String&passed through various callbacks from the StatefulService framework throughout the codebase. There is no evidence of length constraints onoriginIdvalues in the framework layer.The first assignment (line 341) concatenates
_moduleName + "server". The shell output doesn't reveal actual module names used, but the identifier suggests module names should be reasonably short.Key risk: If any external code or framework handler passes an
originIdlonger than 15 characters to theupdateHandlercallback, the assignment at line 367 will silently truncate it. This could break logic that depends on exact string matching for origin IDs (like the.contains("server")check mentioned in the review).Verify: The review comment asks to verify all origin ID assignments, and the practical findings show the actual values used are simple identifiers like "server", "web", "websocket"—all under 15 characters. However, without compile-time or runtime checks, there's no guarantee against future extensions or external originId values that exceed the limit.
Verify that Char<16> is sufficient for all updateOriginId values.
The change from
StringtoChar<16>reduces heap allocations, but introduces truncation risk. From the codebase search,updateOriginIdis assigned at two points:
- Line 341:
updateOriginId = _moduleName + "server"— Risk depends on _moduleName length- Line 367:
updateOriginId = originId— Directly receivesconst String&from framework handlers without length validationCurrent usage patterns show simple identifiers ("server", "web", "websocket"), all under 15 characters. However, Char<16> provides silent truncation with no error feedback. If origin IDs can be extended externally or dynamically generated with longer values, truncation could cause logic errors in string comparisons (e.g., the
.contains("server")check).Recommendation: Either add compile-time static assertions or runtime checks to enforce maximum length, or increase to
Char<32>for safety margin against future extensions.

Verify that Char<16> capacity is sufficient for all property names and values.
The heap optimization replacing String with Char<16> (15 usable characters) is excellent for reducing allocations. However, the comment on line 32 notes "smaller then 11 bytes mostly" for oldValue, which suggests you've analyzed typical usage.
Please verify:
- Property names: Can any module property name exceed 15 characters? (e.g., "boardPreset", "modded", "usage" are all under 15, but check all modules)
- Parent names: Can any parent/array names exceed 15 characters?
- Old values: While most are under 11 bytes, what happens when a longer value (e.g., a UUID, path, or JSON string) is assigned to
oldValue?
Run the following script to check for potential overflows:
If any names exceed 15 characters, consider:
- Increasing
Char<16>toChar<32>for specific fields - Adding truncation with a warning log when assigning to
Char<16> - Using a compile-time assertion to catch oversized literals

And several at exactly 16 characters: customRuleString, oscillatorOffset, macroMutatorFreq, microMutatorFreq, Rectangle height, horizontalPanels, channelsPerOutput, colorwheelbrightness.
At lines 213 and 256 in src/MoonBase/Module.cpp, property names are assigned to updatedItem.name:
updatedItem.name = property.key(); // Line 213
updatedItem.name = key; // Line 256Since Char<16> can hold only 15 characters, these names will silently truncate, breaking property tracking and updates.
Required fixes:
- Increase

🤖 Prompt for AI Agents
In src/MoonBase/Module.h around lines 27 to 34, UpdatedItem's Char<16> fields
for parent and name are too small and truncate property names; change parent and
name to Char<32> to safely hold names up to 31 characters, and add a safeguard
that validates incoming property names before assignment (preferably a constexpr
static_assert for max supported length and/or a runtime check that logs/errors
when a name exceeds the capacity) so oversized names are caught instead of
silently truncated.

@coderabbitai, I want to save on memory, I think this will work fine assuming the first 15 characters will be unique so I think the statement: breaking property tracking and updates. is not happening. But please prove me wrong
If you prove me wrong, I can increase to Char<20> and make sure names are not longer then 19, but my IT brain says multiples of 2,4,8,16,32,64 etc is better (also they fit nicer in the heap then). Or is that bollocks?

cat << 'EOF'
ESP32 (Xtensa LX6) alignment rules:
- char: 1-byte aligned, no padding
- uint8_t: 1-byte aligned, no padding
- JsonVariant: typically 16 bytes, 4-byte or 8-byte aligned
- Struct padding: aligned to largest member's alignment requirement
For UpdatedItem struct:
1. Char<N> parent[2] - N bytes each, total 2*N bytes
2. uint8_t index[2] - 2 bytes
3. Char<N> name - N bytes
4. Char<N> oldValue - N bytes
5. JsonVariant value - 16 bytes (assume 8-byte aligned)
Padding calculation:
- After 2*N + 2 + N + N bytes (4*N + 2), need padding to align JsonVariant
- If JsonVariant needs 8-byte alignment:
* Char<16>: 4*16 + 2 = 66, pad to 72, + 16 = 88 bytes ✓ (matches comment)
* Char<20>: 4*20 + 2 = 82, pad to 88, + 16 = 104 bytes
* Char<24>: 4*24 + 2 = 98, pad to 104, + 16 = 120 bytes
* Char<32>: 4*32 + 2 = 130, pad to 136, + 16 = 152 bytes
Power-of-2 sizing for char arrays:
- DOES NOT affect struct padding (padding depends on alignment, not size)
- Char<20> vs Char<16>: ~16 byte increase per UpdatedItem
- Char<24> vs Char<16>: ~32 byte increase per UpdatedItem
- Char<32> vs Char<16>: ~64 byte increase per UpdatedItem
UpdatedItem instances are typically:
- Stack-allocated in callbacks (short-lived)
- NOT stored long-term in arrays
Conclusion on power-of-2:
- For char arrays: NO significant benefit
- For integer types: YES, can affect performance
- Struct padding: depends on member alignment, not sizes

If NO collisions found:
- Char<16> is SAFE for name matching
- Truncation is acceptable since first 15 chars are unique
- Your intuition is CORRECT
If COLLISIONS found:
- Must use larger size or ensure names are shortened

@ewowi, You are absolutely right! I owe you an apology. The analysis proves your intuition is correct:
✅ Evidence: No Collisions Found
Out of 211 unique property names, all 15-character prefixes are unique. Here are the longest names and their truncations:
21 chars: gravityChangeInterval → "gravityChangeIn"
20 chars: colorwheelbrightness → "colorwheelbrigh"
19 chars: startingLifeDensity → "startingLifeDen"
19 chars: number of Particles → "number of Parti"
18 chars: universesPerOutput → "universesPerOut"
17 chars: channelsPerOutput → "channelsPerOutp"
16 chars: customRuleString → "customRuleStrin"
None of these 15-character prefixes collide with any other property name. Your statement that "the first 15 characters will be unique" is factually correct, so property tracking will NOT break.
About Power-of-2 Sizing
Your IT brain is right about power-of-2 for many scenarios (integers, cache lines, memory pools), but for char arrays inside structs, it's actually less relevant:
UpdatedItem Struct Sizes (with 8-byte alignment for JsonVariant):
Char<16>: 88 bytes ← current
Char<20>: 104 bytes (+16 bytes)
Char<24>: 120 bytes (+32 bytes)
Char<32>: 152 bytes (+64 bytes)
Key insight: The struct padding is determined by JsonVariant's alignment requirement (8 bytes), not by whether the char array size is a power of 2. So:
Char<16>vsChar<20>→ both pad to 8-byte boundaries for JsonVariant- Going from 16→20 saves only 4 bytes per field × 4 fields = 16 bytes total
- Power-of-2 doesn't give you extra alignment benefits here
My Recommendation
Keep Char<16> as-is. It's safe and saves ~16 bytes per UpdatedItem compared to Char<20>, and ~64 bytes compared to Char<32>. Since UpdatedItem is stack-allocated (short-lived), this is a sensible optimization.
Minor trade-offs to be aware of:
- Debugging: Truncated names in logs might be slightly harder to read (e.g., "customRuleStrin" instead of "customRuleString")
- Future-proofing: New property names should keep the first 15 characters unique (a comment or static_assert could help)
Optional safeguard (if you want extra peace of mind):
// Add to Char::operator= to catch truncation in debug builds
#ifdef DEBUG
if (strlen(str) >= N) {
EXT_LOGW("Char", "Truncating '%s' to %d chars", str, N-1);
}
#endifBottom line: No functional breakage. Your optimization is solid! 🎯

@coderabbitai, in ModuleIO.h::setBoardPresetDefaults, calling update(object, ModuleState::update, _moduleName + "server"); crashes the esp32: on esp32-D0, while it runs fine on ESP32-S3 (having PSRAM). setBoardPresetDefaults creates a relatively big, but absolutely not so big json document.

@coderabbitai, regarding setBoardPresetDefaults (see above). None of Solution 1,2 and 3 worked, I tried them independently and combined. Regarding updateWithoutPropagation: that's not how it works. the update fires all the onUpdates already, WithoutPropagation means no added updateHandlers are fired. Could the solution be that the used JsonDocument doc, which is now a local variable of setBoardPresetDefaults is moved to a global place, to be reused by all functions needing temp jsondocuments? |

I've now identified the critical difference between 🔍 Root Cause: Call Stack Depth, Not Just JsonDocument SizeModuleTasks (works fine): JsonDocument root; // Line 71 - LOCAL variable

✅ Solution: Move setBoardPresetDefaults Execution Out of onUpdateThe issue is that Option 1: Queue setBoardPresetDefaults for Later Execution (Recommended)// In ModuleIO.h onUpdate()
void onUpdate(const UpdatedItem& updatedItem) override {
if (updatedItem.name == "boardPreset" && !updateOriginId.contains("server")) {
#if FT_ENABLED(FT_MOONLIGHT)

std::mutex runInAppTask_mutex;
// Pre-allocate capacity to avoid reallocation fragmentation
void initRunInAppTask() {
runInAppTask.reserve(100); // Reserve space for 100 tasks upfront
}
// Call this from setup() in main.cpp
#endifThen in main.cpp void setup() {
#if FT_ENABLED(FT_MOONLIGHT)
initRunInAppTask(); // Pre-allocate vector capacity
#endif
// ... rest of setup
}Option 3: Increase driverTask Stack (Backup Plan)In main.cpp: xTaskCreateUniversal(driverTask,
"AppDriverTask",
(psramFound() ? 6 : 8) * 1024, // 4KB → 8KB on D0
NULL,

&driverTaskHandle,

@coderabbitai, I am about to push a commit with some of your advices implemented, but not all: You want JsonDocument to be shared instead of function variables, because of minimal heap/stack. You say it is easy 1000 bytes, but in ArduinoJson v7 it is very small sizeof(JsonDocument) says 16 bytes, so until further notice I will not yet do it. |

Tip For best results, initiate chat on the files or code changes. @ewowi, you're absolutely right on both points! 👍 JsonDocument in ArduinoJson v7You're correct that Core Functionality PhilosophyI completely agree with your engineering approach:
This is spot-on for embedded systems. If semaphore creation fails, the system is already in an unrecoverable state—defensive checks there just add complexity without real benefit. Better to:
Real Memory Pressure PointsYou've correctly identified where the actual memory challenges are:
These do need runtime bounds checking and graceful degradation since they're user-dependent. Would you like help implementing runtime safeguards for those variable components? For example:
Otherwise, looking forward to seeing your commit! The shared router refactoring you've implemented should already free up significant memory for those variable components. 🚀 🧠 Learnings used |

124-134: Inconsistent IP reporting in writeUDP() with new ETH support.The connectivity guards now allow operation when ETH is connected, but line 132 hardcodes
WiFi.localIP()when announcing the device. If only Ethernet is connected, this will report an invalid or empty IP address.Consider using the appropriate interface IP based on which is connected:
void writeUDP() { if (deviceUDP.beginPacket(IPAddress(255, 255, 255, 255), deviceUDPPort)) { UDPMessage message; message.name = esp32sveltekit.getWiFiSettingsService()->getHostname().c_str(); deviceUDP.write((uint8_t*)&message, sizeof(message)); deviceUDP.endPacket(); - // EXT_LOGD(MB_TAG, "UDP packet written (%s -> %d)", message.name.c_str(), WiFi.localIP()[3]); + IPAddress activeIP = WiFi.localIP() ?

88-103: Consider using pooled JsonDocument for transmitData.Per learnings, on ESP32-D0 boards without PSRAM, large module states can cause heap exhaustion when allocating JsonDocument locally. Consider using the global

5-10: Missing include for WEB_SOCKET_ORIGIN macros.
WEB_SOCKET_ORIGIN(line 48) andWEB_SOCKET_ORIGIN_CLIENT_ID_PREFIX(line 74) are defined inWebSocketServer.hbut not included here.

80-85: Substring matching may match unintended modules.This issue was previously flagged. Using
contains()can incorrectly match if one module name is a substring of another.src/MoonBase/SharedFSPersistence.h (3)
74-84: Consider using global JsonDocument pool for large module states.Based on learnings, ESP32-D0 boards without PSRAM can crash when deserializing large module states (e.g., ModuleIO with 50+ GPIO pins) due to heap exhaustion. Consider using the global
gTempDocpool protected by mutex, as recommended in previous reviews.
10-11: Global delayed writes queue lacks thread synchronization.The
sharedDelayedWritesvector is accessed from multiple contexts (update handlers,writeToFSDelayed) without mutex protection. On ESP32, concurrent access from HTTP/WebSocket handlers and the main loop can cause data races.+#include <mutex> + // ADDED: Global delayed writes queue (matches templated version) inline std::vector<std::function<void(char)>> sharedDelayedWrites; +inline std::mutex sharedDelayedWritesMutex;Then wrap accesses in

38-38: StaticupdateOriginIdlacks thread synchronization.
ModuleState::updateOriginIdis a static variable written byModuleState::update()(line 265) and potentially read by other code paths. Without synchronization, concurrent updates from HTTP/WebSocket handlers can cause race conditions where the wrong originId is observed.Consider making this a per-instance field or adding mutex protection.
src/MoonBase/Module.h (2)
63-72: Shared gModulesDoc lifetime and cleanup now look correct for the single-constructor pattern.The switch to
extern JsonDocument* gModulesDocwith lazy allocation in the constructor and null-guarded cleanup in the destructor resolves the earlier linkage and null-dereference issues. Given that modules (and theirModuleStates) are constructed statically and never deleted at runtime, the one-timenew JsonDocument(...)plus per-instanceadd<JsonObject>()and destructor-sidearr.remove(i)is a reasonable trade-off between RAM usage and simplicity. No additional mutexing is needed here under the current initialization model.Also applies to: 79-94
57-61: Binary semaphore creation/usage lacks NULL guards and can hard-fault on low heap; also handshake assumes semaphores always exist.
xSemaphoreCreateBinary()can returnnullptrunder memory pressure; today you immediately callxSemaphoreGive(updateProcessedSem)in the constructor and laterxSemaphoreTake/xSemaphoreGiveinpostUpdate()/getUpdate()with no handle checks. On an ESP32-D0 already close to its heap limits, this will result in a crash rather than a graceful degradation when semaphore allocation fails.You can keep the nice bounded producer/consumer design but make it fail-safe like this:
ModuleState() { EXT_LOGD(MB_TAG, "ModuleState constructor"); - updateReadySem = xSemaphoreCreateBinary(); // assuming this will be successful - updateProcessedSem = xSemaphoreCreateBinary(); // assuming this will be successful - xSemaphoreGive(updateProcessedSem); // Ready for first update + updateReadySem = xSemaphoreCreateBinary(); + updateProcessedSem = xSemaphoreCreateBinary(); + if (!updateReadySem || !updateProcessedSem) { + EXT_LOGE(MB_TAG, "Failed to create update semaphores"); + if (updateReadySem) { + vSemaphoreDelete(updateReadySem); + updateReadySem = nullptr; + } + if (updateProcessedSem) { + vSemaphoreDelete(updateProcessedSem); + updateProcessedSem = nullptr; + } + // Fall back to direct processing in postUpdate() when semaphores are missing. + } else { + // Ready for first update + xSemaphoreGive(updateProcessedSem); + } } @@ ~ModuleState() { @@ - if (updateReadySem) vSemaphoreDelete(updateReadySem); - if (updateProcessedSem) vSemaphoreDelete(updateProcessedSem); + if (updateReadySem) vSemaphoreDelete(updateReadySem); + if (updateProcessedSem) vSemaphoreDelete(updateProcessedSem); } @@ void postUpdate(const UpdatedItem& updatedItem) { @@ - if (contains(taskName, "SvelteKit") || contains(taskName, "loopTask")) { // at boot, the loopTask starts, after that the loopTask is destroyed + if (contains(taskName, "SvelteKit") || contains(taskName, "loopTask")) { // at boot, the loopTask starts, after that the loopTask is destroyed if (processUpdatedItem) processUpdatedItem(updatedItem); } else { - if (xSemaphoreTake(updateProcessedSem, portMAX_DELAY) == pdTRUE) { + // If semaphores are unavailable (OOM at init), fall back to direct processing. + if (!updateReadySem || !updateProcessedSem) { + if (processUpdatedItem) processUpdatedItem(updatedItem); + return; + } + if (xSemaphoreTake(updateProcessedSem, portMAX_DELAY) == pdTRUE) { this->updatedItem = updatedItem; xSemaphoreGive(updateReadySem); } @@ bool getUpdate() { - if (xSemaphoreTake(updateReadySem, 0) == pdTRUE) { + if (!updateReadySem || !updateProcessedSem) return false; + if (xSemaphoreTake(updateReadySem, 0) == pdTRUE) { if (processUpdatedItem) processUpdatedItem(updatedItem); xSemaphoreGive(updateProcessedSem); return true; // Update retrievedThis keeps heap usage bounded (at most one

50-56: onUpdate signature is heap‑friendly; consider addingoverrideand markingoldValueunusedSwitching to
const Char<20>& oldValueandJsonObjectis aligned with the heap‑reduction goals (no per‑updateStringallocations, JsonObject is a lightweight handle). The body currently ignoresoldValue, though, and the function isn’t markedoverridelike inD_VirtualDriver.h.To tighten this up without behavior change:
- void onUpdate(const Char<20>& oldValue, const JsonObject control) { + void onUpdate(const Char<20>& /*oldValue*/, const JsonObject control) override {or equivalently cast to void inside the body to silence “unused parameter” warnings.

173-175: ArduinoJson JsonVariant usage is acceptable but could be simplifiedUsing
root["heap_info_app"].to<JsonVariant>()/.to<JsonVariant>()and thenvariant.set(...)works, but is a bit roundabout for just storing a string. You could equivalently passroot["heap_info_app"]/root["heap_info_dma"]directly toheapHealthand callvariant.set(...)there without.to<>(), which keeps the code slightly simpler and avoids an extra template call. This is purely stylistic; current code is correct.interface/src/routes/system/status/SystemStatus.svelte (2)
164-173: Docs link: semantics OK, consider precomputing GitHub parts (optional)The reflowed anchor markup looks fine and keeps behavior unchanged. If you ever touch this again, consider computing
owner/repoonce in<script>(or exposing a helper) instead of callingpage.data.github.split('/')twice in the template for readability and to avoid repeated work on re-renders.
208-237: Battery visibility condition and sub‑blocks look correctThe guard on
page.data.features.batteryplus the>= 0checks forsoc,voltage, andcurrentmatches the intended “only show when valid” behavior, and the nested blocks render each metric independently. This is a nice, explicit structure; no functional issues spotted.If you want to trim template noise later, you could destructure
$telemetry.batteryinto local variables in<script>or a$derivedstore and reference those instead of repeating$telemetry.battery.*in the markup.interface/vite.config.ts (1)
21-26: Hardcoded development IP should not be committed.These proxy target IPs (192.168.1.152) are developer-specific and will break for other contributors with different network setups. Consider using environment variables or a local override file (e.g.,
.env.localor a gitignoredvite.config.local.ts).+// Add to .env.local (gitignored): +// VITE_DEV_TARGET=192.168.1.152 '/rest': { - target: 'http://192.168.1.152', + target: `http://${process.env.VITE_DEV_TARGET || 'localhost'}`, changeOrigin: true }, '/ws': { - target: 'ws://192.168.1.152', + target: `ws://${process.env.VITE_DEV_TARGET || 'localhost'}`, changeOrigin: true, ws: true }src/MoonBase/SharedWebSocketServer.h (1)

23-29: UpdatedItem Char<20> vs earlier Char<16> is a small RAM regression; consider reverting for tighter heap use.Given the prior analysis that all property names have unique 15-character prefixes and typical
oldValuestrings are short,Char<16>remained safe forparent,name, andoldValue. Moving toChar<20>slightly increasesUpdatedItem(and thus eachModuleState) size for relatively little functional gain. If you still want maximum heap headroom on ESP32-D0, consider reverting the fields back toChar<16>(or selectively usingChar<16>forparent/nameand keeping more space only where really needed), accepting the already-verified prefix-uniqueness constraint.
Based on learnings, all property names have unique 15-character prefixes.
55-56: Static updateOriginId couples all modules; ensure the single-writer assumption holds or encapsulate origin per update.
updateOriginIdbeing a staticChar<20>shared across allModuleStateinstances and read inModule::processUpdatedItem()is a clever way to propagate origin through nested updates, but it does rely on only one update chain being active at a time. If, in the future, two tasks can concurrently callModuleState::update(...)with differentoriginIds, they will race on the same static buffer andsaveNeededdecisions may become non-deterministic.If your architecture truly guarantees a single producer (e.g., one HTTP/SvelteKit task) updating modules at a time, at minimum consider adding a comment here documenting that invariant. If you ever relax that constraint, a safer alternative would be to carry
originIdinUpdatedItemitself or as a per-ModuleStatefield instead of a global static.Also applies to: 156-167
146-154: Loop wiring to getUpdate() is a nice heap-bounded replacement for the old runInAppTask queue.Having
Module::loop()simply call_state.getUpdate()and letting the producer side usepostUpdate()gives you a fixed upper bound of one pendingUpdatedItemper module and avoids the unboundedstd::vectorof captured lambdas that was previously exhausting heap on ESP32-D0 during large updates. Just ensure all derived modules that overrideloop()actually callModule::loop()as the comment states; marking the override withoverridein derived classes will help enforce that at compile time.
181-193: Size-of comments are useful but likely stale after these changes; consider regenerating or removing.The inline
sizeof(...)comments documenting memory footprints (e.g.,sizeof(Module) // 1144) were accurate at the time but are almost certainly out of date now thatModuleStategained semaphores and additional fields. If you rely on these numbers for heap budgeting, it’s worth re-running thesizeofchecks and updating the comments, or alternatively removing them to avoid misleading future readers.Also applies to: 196-199

Learning: On ESP32-D0 boards without PSRAM, creating large local JsonDocument instances (e.g., with 50+ GPIO pins in setBoardPresetDefaults) can cause heap exhaustion and crashes due to insufficient contiguous heap memory. The solution is to use a global pre-allocated JsonDocument pool (gTempDoc) protected by a mutex, which eliminates repeated heap allocation/deallocation and fragmentation.

158-158: The oldValue condition change is correct and aligns with the codebase initialization pattern.The change from
!= "null"to!= ""is intentional and fixes the boot-detection logic:
- oldValue initialization: The
UpdatedItemconstructor does not explicitly initializeoldValue, so it defaults to an empty string (Char<20>()="").- Boot vs. user update: When loading initial state,
oldValue = ""(empty); when a user updates a value,oldValuecontains the previous state value (non-empty).- No "null" assignments: The literal string
"null"is never assigned tooldValueanywhere in the codebase, so the old check was ineffective.- Consistent pattern: Other modules (e.g.,
ModuleIO.hline 396) already use the sameoldValue == ""pattern to detect boot-time initialization.The new check correctly prevents script actions (kill, execute, delete) from running during boot while allowing them on user updates.

269-291: Good memory pre-allocation strategy for module registration.The

330-346: Now I have enough information to complete the verification. The review comment is valid, and I found additional issues:Key findings:
- Documentation mismatch:
docs/moonbase/tasks.mdshows AppEffectTask should use 6KB (PSRAM) / 4KB (non-PSRAM), but the actual code uses 4KB / 3KB- Incorrect comment: The comment says "updated from 4 to 6" but the code shows values reduced from 6 to 4, making the comment backwards
- Stack size concern is valid: 3-4KB is significantly smaller than comparable system tasks (Wi-Fi: 12KB, HTTPD: 6-8KB, OTA: 9KB)
- LiveScript enabled by default: FT_LIVESCRIPT=1 is set in platformio.ini, so 3KB must support LiveScript stack depth
- Stack monitoring in place: The codebase uses
uxTaskGetStackHighWaterMark()in all logging macros, but no indication of validation resultsFinal Output
Update stack size documentation and clarify the stack allocation strategy for non-PSRAM boards.
The reduced stack sizes (3KB for non-PSRAM, 4KB for PSRAM) warrant verification, especially with LiveScript enabled by default. Additionally, the inline comment is outdated—it claims "updated from 4 to 6" but code shows 4KB/3KB; documentation in
docs/moonbase/tasks.mdlists different values (6KB/4KB).Since stack monitoring via
uxTaskGetStackHighWaterMark()is integrated into all logging macros, run tests to confirm 3KB is sufficient under LiveScript load and update the comment to reflect actual changes and any validation results. If the reduction from the documented 6KB/4KB was deliberate, document the rationale and any testing methodology used.src/MoonBase/NodeManager.h (2)
23-23: Good heap optimization: Using fixed-sizeChar<20>instead ofString.Replacing
StringwithChar<20>fordefaultNodeNameeliminates per-instance heap allocation, aligning with the PR's heap optimization goals.

outBuffer(bothStringandvector<uint8_t>) that are reused across calls significantly reduces heap allocation churn. Thereserve()calls withmeasureJson()/measureMsgPack()ensure capacity without repeated reallocations.
111-118: LGTM! Clean refactoring to support pre-constructed JsonDocument.The overload delegation pattern is clean - the
(event, jsonObject)overload builds a document and delegates to the new(JsonDocument)overload, avoiding code duplication.

Guard / normalize new App RAM & DMA RAM fields for older firmware
The new “App RAM” and “DMA RAM” tiles are useful additions and align with the memory‑optimization work. One thing to consider is compatibility with existing devices/firmware that may not yet send heap_info_app / heap_info_dma:
- If these fields are missing or
undefined, the template will currently render the literal stringundefined. - If they’re raw byte counts, the UI will show large integers without units, unlike the other memory tiles.
You can keep the UI behavior but make it more robust and consistent with a small tweak:
- <div class="font-bold">App RAM</div>
- <div class="text-sm opacity-75">
- {systemInformation.heap_info_app}
- </div>
+ <div class="font-bold">App RAM</div>
+ <div class="text-sm opacity-75">
+ {systemInformation.heap_info_app ?? 'n/a'}
+ </div>
...
- <div class="font-bold">DMA RAM</div>
- <div class="text-sm opacity-75">
- {systemInformation.heap_info_dma}
- </div>
+ <div class="font-bold">DMA RAM</div>
+ <div class="text-sm opacity-75">
+ {systemInformation.heap_info_dma ?? 'n/a'}
+ </div>If the backend instead returns fully formatted, human‑readable strings, this keeps that intact while providing a clean fallback.

In interface/src/routes/system/status/SystemStatus.svelte around lines 262 to
287, the new App RAM and DMA RAM tiles can render "undefined" or raw bytes for
older firmware; update the template to guard and normalize these fields: check
each of systemInformation.heap_info_app and heap_info_dma and if undefined/null
show a safe fallback like "N/A" or "—", if the value is a number convert it to a
human-readable unit string (KB/MB/GB) via the existing bytes-format helper or a
small helper function, and otherwise render the value as-is so preformatted

In src/MoonBase/Modules/ModuleTasks.h around line 99, the expression "100 *
ts->ulRunTimeCounter / totalRunTime" can overflow uint32_t before division;
change the calculation to perform it in 64-bit and guard against
division-by-zero — e.g., cast operands to uint64_t and compute
(uint64_t)ts->ulRunTimeCounter * 100 / (uint64_t)totalRunTime (or divide first
if preferred) so the multiplication cannot overflow, and ensure totalRunTime !=
0 before formatting the percentage.

Add #include <HttpEndpoint.h> to src/MoonBase/SharedHttpEndpoint.h.
The constant HTTP_ENDPOINT_ORIGIN_ID is defined in lib/framework/HttpEndpoint.h (line 11) but is not included in SharedHttpEndpoint.h. The file uses this constant at line 70 without having access to its definition. This will cause a compilation error. The pattern throughout the codebase shows files explicitly include HttpEndpoint.h when they need HTTP_ENDPOINT_ORIGIN_ID.

Substring matching may match unintended modules.
Using contains() can incorrectly match if one module name is a substring of another (e.g., "IO" would match "/ws/ModuleIO"). Use exact suffix matching instead.

In src/MoonBase/SharedWebSocketServer.h around lines 105 to 110, the findModule

suffix matching of the module name against the path (for example, check that the
path ends with the module name and that the character before the suffix is a
path separator such as '/'), using std::string methods (rfind/compare or substr)
to ensure exact match of the module name at the end of the path and return the
module only when that exact suffix condition holds.

<function_calls>
#!/bin/bash
Look for similar callback patterns in related files
rg "updateHandler|onUpdate|update.*Handler" --type h --type cpp -B5 -A5 | head -n 100
Let me check nearby files for context on how updates are handled:

Let me check the Module.h file directly:
<function_calls>
#!/bin/bash
Check if Module.h exists and contains type information
find . -name "Module.h" | xargs head -n 100
Let me verify the exact behavior we need to check. Based on ArduinoJson documentation:
<function_calls>
"JsonVariant" "as<const char*>" EXT_LOGD format string %s
</function_calls>
Now let me check Arduino String comparison implementation:
<function_calls>
"Arduino String" "operator==" "const char*" implicit conversion JsonVariant
</function_calls>
Let me search for how comparison happens at line 51:
<function_calls>
#!/bin/bash
The pattern is: if (updatedItem == nodeState["name"])
updatedItem appears to be std::string or Arduino String (likely const std::string&)
nodeState["name"] is JsonVariant
Search for JsonVariant operator== implementations in the codebase

rg "nodeState\s*=" --type h --type cpp -B3 -A3 | head -n 150
Based on my investigation, let me create a comprehensive analysis. Let me check one more crucial thing - whether the code actually compiles and how the comparison works:
<function_calls>
#!/bin/bash
Search for JsonObject or DynamicJsonDocument to understand nodeState type better
rg "DynamicJsonDocument|JsonObject|StaticJsonDocument" --type h --type cpp -B2 -A2 | head -n 100
Let me now look for the specific pattern where the pointer might be null:
<function_calls>
#!/bin/bash
Search for logging patterns that handle null from .as()
rg 'EXT_LOGD.*%s' --type h --type cpp | head -n 20
Check if there are any safe logging patterns in the codebase
rg 'as<const char.*?(' --type h --type cpp -A3 | grep -B1 -A2 "EXT_LOGD|printf|log"
Let me verify the ArduinoJson behavior specifically for null safety in format strings:
<function_calls>
ArduinoJson 6.x JsonVariant["key"].as<const char*>() behavior missing key or wrong type
</function_calls>
Let me make a final comprehensive check of the actual safety issue:
<function_calls>
#!/bin/bash
Final verification - check if there are ANY guards around similar patterns
python3 << 'PYEOF'
import re
with open("src/MoonLight/Modules/ModuleLiveScripts.h") as f:
content = f.read()
Find all .as<const char*>() calls
pattern = r'.as<const char\s**>\s*()'
matches = list(re.finditer(pattern, content))
print(f"Found {len(matches)} uses of .as<const char*>()")
lines = content.split('\n')
for match in matches:
# Find line number
line_num = content[:match.start()].count('\n') + 1
line_content = lines[line_num - 1]
print(f"\nLine {line_num}: {line_content.strip()}")
# Check if result is immediately used in a format string
after = content[match.end():match.end()+100]
print(f" After: {after[:60]}")
PYEOF
Now let me verify the key comparison semantic issue:
<function_calls>
#!/bin/bash
Understand what happens when you compare std::string with JsonVariant
Check if there's an operator== that handles this
python3 << 'PYEOF'
Check ArduinoJson documentation and common patterns
The issue is:
Line 51: if (updatedItem == nodeState["name"])
updatedItem is likely const std::string& (from function parameter)
nodeState["name"] is JsonVariant
For this to work, JsonVariant must have operator==(const std::string&)
or operator==(const char*) or similar
Let's verify by checking includes and available comparison operators
with open("src/MoonLight/Modules/ModuleLiveScripts.h") as f:
lines = f.readlines()
print("Key code snippets:")
print("\nLine 51-53:")
for i in range(50, 53):
print(f" {i+1}: {lines[i].rstrip()}")
print("\nLine 62:")
print(f" 62: {lines[61].rstrip()}")
print("\n\nAnalysis:")
print("- Line 51: if (updatedItem == nodeState["name"])")
print(" Requires: JsonVariant::operator==(std::string) or similar")
print(" Or: std::string::operator==(JsonVariant) if JsonVariant converts to const char*")
print()
print("- Line 62: EXT_LOGD(ML_TAG, "update due to new node %s done", nodeState["name"].as<const char >())")
print(" Issue: If nodeState["name"] is not a string or doesn't exist,")
print(" .as<const char>() might return nullptr, which will crash in printf with %s")
PYEOF
Perfect! Now I have enough information. Let me verify one more time by searching for how ArduinoJson behaves:
<function_calls>
ArduinoJson6 JsonVariant::operator== const char*
</function_calls>
Let me check for the null return behavior explicitly:
<function_calls>
ArduinoJson JsonElement as method returns null pointer missing field
</function_calls>
Based on my thorough investigation, let me now write the rewritten review comment:
Guard against null pointer when logging nodeState["name"].as<const char*>().
At line 62, nodeState["name"].as<const char*>() may return nullptr if the "name" field is missing from the JSON document or is not a string type. Passing a null pointer to the %s format specifier in EXT_LOGD causes undefined behavior and crashes on ESP32.
Additionally, verify that the comparison at line 51 (if (updatedItem == nodeState["name"])) is safe. This requires JsonVariant to have an appropriate operator== overload that accepts the type of updatedItem, or a conversion operator that allows the comparison.
Apply this fix to the logging call:
- EXT_LOGD(ML_TAG, "update due to new node %s done", nodeState["name"].as<const char *>());
+ const char* nodeName = nodeState["name"].as<const char*>();
+ EXT_LOGD(ML_TAG, "update due to new node %s done", nodeName ? nodeName : "<null>");Also applies to: 62-62

In src/MoonLight/Modules/ModuleLiveScripts.h (around lines 51–62), retrieve
nodeState["name"] into a const char* first, check it for nullptr before using it
in the if comparison and in EXT_LOGD (e.g., const char* name =
nodeState["name"].as<const char*>(); if (name && updatedItem == name) { ...
EXT_LOGD(..., name); } else { EXT_LOGD(..., name ? name : "<missing>"); }), and
ensure the comparison uses the C-string (or convert to std::string) rather than
relying on an implicit operator== between UpdatedItem and JsonVariant.

Guard against null when logging nodeState["name"] in drivers section.
The same null-pointer concern from the effects section applies here. At line 81, nodeState["name"].as<const char*>() may return nullptr, causing undefined behavior when passed to %s in EXT_LOGD.
Apply this diff to guard the logging:

In src/MoonLight/Modules/ModuleLiveScripts.h around lines 67-72 and line 81,
guard against nodeState["name"] being null before passing it to EXT_LOGD and
findLiveScriptNode: read the name into a const char* via
nodeState["name"].as<const char*>(), check if it's nullptr and substitute a safe
fallback like "<null>" for logging and for the findLiveScriptNode call, and also
ensure you check the returned LiveScriptNode* for nullptr before dereferencing
or using it.

@coderabbitai, here are some notes on your comments. Wait with replying until I add my next commit, that you can make one reply on both instead of 2: scriptState["name"] should never be null, and if so it is a dev error which should be fixed. Regarding #62 (comment) : Note: SharedFSPresistence is not used yet. I will use it in one of the subsequent commits |
|
Tip For best results, initiate chat on the files or code changes. @ewowi, thank you for the detailed feedback! I understand and will wait for your next commit before providing a consolidated reply. This will keep the PR review thread cleaner and more focused. I've noted all your points:
Looking forward to your next commit! 🚀 ✏️ Learnings added

src/MoonBase/Modules/ModuleDevices.h (3)
50-62: Dual-interface IP guard is logically correct; consider centralizing active-IP logic.The new
if (!WiFi.localIP() && !ETH.localIP()) return;checks inloop1s()andloop10s()correctly ensure at least one interface is up before doing UDP I/O. That’s a good correctness + small CPU/heap win (no UDP work when fully offline).To reduce duplication and make the WiFi/ETH selection more self-documenting, you could optionally introduce a small helper:
+inline IPAddress getActiveIP() { + IPAddress ip = WiFi.localIP(); + if (!ip) ip = ETH.localIP(); + return ip; +} void loop1s() { if (!_socket->getConnectedClients()) return; - if (!WiFi.localIP() && !ETH.localIP()) return; + if (!getActiveIP()) return; ... } void loop10s() { if (!_socket->getConnectedClients()) return; - if (!WiFi.localIP() && !ETH.localIP()) return; + if (!getActiveIP()) return; ... }This avoids repeating the WiFi/ETH condition and makes the “active IP” concept explicit.
73-111: New IP guard inupdateDevices()is good; a couple of small heap trims are possible nearby.The added
if (!WiFi.localIP() && !ETH.localIP()) return;before building/sending the JSON snapshot is helpful: when the node has no IP, you now skip thestd::vectorbuild, sort, andJsonDocumentallocation, which is a nice small win on constrained heap.Right around here you can shave a bit more heap churn with minimal change:
- Avoid repeated
ip.toString()allocations in the loop and on insert:- for (JsonObject dev : _state.data["devices"].as<JsonArray>()) { - if (dev["ip"] == ip.toString()) { + String ipStr = ip.toString(); // one allocation + for (JsonObject dev : _state.data["devices"].as<JsonArray>()) { + if (dev["ip"] == ipStr) { device = dev; ... } } if (device.isNull()) { device = _state.data["devices"].as<JsonArray>().add<JsonObject>(); EXT_LOGD(ML_TAG, "added ...%d %s", ip[3], name); - device["ip"] = ip.toString(); + device["ip"] = ipStr; }This removes multiple transient
Stringallocations per call, which helps heap fragmentation on ESP32, especially ifupdateDevices()is hit frequently.
- Optional (only if device lists can grow large): if you expect many devices, consider whether
std::vector<JsonObject>+std::sortplus a freshJsonDocument devices;each time is acceptable on D0 boards. If not, a small fixed-capacity container or reusing a sharedJsonDocument/buffer (as you do elsewhere) could further reduce heap pressure. Otherwise, the current approach is fine. Based on learnings, focus on this only if device counts are realistically high.
124-134:activeIPselection is correct; minor clarity/refactor improvement possible.Picking
activeIP = WiFi.localIP() ? WiFi.localIP() : ETH.localIP();and feeding it intoupdateDevices()fixes the previous WiFi-only behavior for Ethernet-only setups and aligns with the new guards.For readability and reuse with the other IP checks, you could align this with a shared helper (as sketched earlier):
- IPAddress activeIP = WiFi.localIP() ? WiFi.localIP() : ETH.localIP(); + IPAddress activeIP = getActiveIP(); + if (!activeIP) return; // defensive, if you want extra safety // EXT_LOGD(MB_TAG, "UDP packet written (%s -> %d)", message.name.c_str(), activeIP[3]); updateDevices(message.name.c_str(), activeIP);This keeps the “pick WiFi, else ETH” rule in one place and avoids subtle differences if more call sites appear later.

36-38: SolidEffect white-channel loop fix is correct; optional micro‑optimizationInitialization of
indexin the loop header is correct and fixes the previous undefined behavior. If you want a tiny CPU win, you could precompute the brightness‑scaled white once before the loop:- if (layer->layerP->lights.header.offsetWhite != UINT8_MAX && white > 0) - for (int index = 0; index < layer->nrOfLights; index++) layer->setWhite(index, white * brightness / 255); + if (layer->layerP->lights.header.offsetWhite != UINT8_MAX && white > 0) { + const uint8_t whiteLevel = white * brightness / 255; + for (int index = 0; index < layer->nrOfLights; index++) { + layer->setWhite(index, whiteLevel); + } + }
264-271: Caching active IP is fine; consider avoiding doubleWiFi.localIP()and handling no‑IP case
IPAddress activeIP = WiFi.localIP() ? WiFi.localIP() : ETH.localIP();is heap‑neutral and works, but it callsWiFi.localIP()twice and assumes at least one interface has a non‑zero IP. You could improve clarity and robustness by caching once and falling back explicitly if both are unset:- IPAddress activeIP = WiFi.localIP() ? WiFi.localIP() : ETH.localIP(); + IPAddress wifiIP = WiFi.localIP(); + IPAddress ethIP = ETH.localIP(); + IPAddress activeIP = wifiIP ? wifiIP : ethIP; + // Optional: if both are 0.0.0.0, show a placeholder instead of ".0"Then continue to use
activeIP[3]as you do now.lib/framework/APSettingsService.h (1)
52-54: Origin-aware update signature is consistent; consider markingoriginIdunusedAdding
originIdtoAPSettings::updatekeeps it consistent with other settings services, even though it’s currently unused. To avoid compiler warnings, you might want to mark it as intentionally unused (e.g.,(void)originId;or an[[maybe_unused]]attribute).Also applies to: 115-144
src/MoonBase/SharedEventEndpoint.h (1)
27-60: Heap-friendly captures; consider reusing the global JsonDocument pool insyncStateGood:
registerModulelambdas capturemoduleby pointer, avoiding per‑handlerStringallocations, andsyncStateearly‑returns when there are no connected clients.If you still want to squeeze heap usage on ESP32‑D0, consider reusing the shared
gTempDoc(with its mutex) insidesyncStateinstead of a freshJsonDocument doc;each time, especially for large module states. That keeps the JSON serialization buffer contiguous and avoids repeated allocate/free cycles.src/MoonBase/Module.h (2)
51-56: New semaphore-basedpostUpdate/getUpdateflow is heap-friendly but relies on the loop() contractThe producer/consumer pattern using
updateReadySem/updateProcessedSemandpostUpdate/getUpdatenicely replaces the prior unbounded lambda queue with a single in‑flightUpdatedItemper module, which is much safer for heap usage.The trade‑off is that correct behavior now depends on every module that overrides
loop()callingModule::loop()sogetUpdate()runs; otherwise producers can block indefinitely. You might eventually want a small helper (e.g., a non‑virtualloop()that calls a virtualloopImpl()) to make that contract harder to violate, but the current design is workable if callers respect the comment.Also applies to: 116-137, 149-168
55-56: StaticupdateOriginIdis efficient but assumes serialized updatesUsing a single static
Char<20> updateOriginIdwritten byModuleState::updateand consumed inprocessUpdatedItemkeeps memory overhead low, but it implicitly assumes only one update is “active” at a time across tasks. If you ever introduce true parallel updates from different origins, you may want to move the origin ID into per‑state or per‑update context instead of a static.Given current architecture (single app loop + serialized update paths), this is acceptable; just something to keep in mind for future concurrency changes.

Learning: On ESP32-D0 boards without PSRAM, creating large local JsonDocument instances (e.g., with 50+ GPIO pins in setBoardPresetDefaults) can cause heap exhaustion and crashes due to insufficient contiguous heap memory. The solution is to use a global pre-allocated JsonDocument pool (gTempDoc) protected by a mutex, which eliminates repeated heap allocation/deallocation and fragmentation.

Learning: On MoonLight ESP32 firmware, core infrastructure components (semaphores, basic memory allocations for Module initialization, etc.) are expected to succeed and should be validated through testing rather than runtime NULL guards. Memory safeguards should focus on variable/user-configurable components like lights.channels arrays, mappingTable sizes, and Node counts that vary per user configuration.

19-19: AP channel default change appears orthogonal to heap optimization PR objectives.The change from channel 1 to channel 6 is a reasonable WiFi best practice (channel 6 sits in the center of the spectrum and typically experiences less interference), and the comment clearly documents the rationale. However, this configuration update is not mentioned in the PR objectives, which focus on heap optimization, shared routers, and memory-bounded queuing.
Please confirm whether this configuration change is intended as part of this heap optimization PR or should be submitted separately.

925-930: RubiksCubeEffect::onUpdate signature change is consistent and avoidsStringheap usageSwitching to
void onUpdate(const Char<20>& oldValue, const JsonObject control) overridealigns this node with the new Char-based API (as in other nodes) and removes the ArduinoString&from the callback path, which helps keep heap usage down on ESP32. The body only inspectscontrol["name"]and remains behaviorally equivalent.
1110-1126: ParticlesEffect::onUpdate updated to new signature; behavior unchanged and heap‑friendlyThe new
onUpdate(const Char<20>& oldValue, const JsonObject control) overridematches the standardized callback signature and keeps heap allocations out of the parameter list. Re‑initializing particles only when"number of Particles"or"barriers"change is the same behavior as before and reuses the existing staticparticles[255]buffer, so no new heap pressure is introduced.lib/framework/FSPersistence.h (1)
176-181: Switch toto<JsonObject>()inapplyDefaultslooks correctUsing
jsonDocument.to<JsonObject>()here is consistent with other call sites and ArduinoJson v7 patterns; it guarantees the root is an object before passing it into_stateUpdater.src/MoonBase/Module.h (1)
23-37: UpdatedItem and ModuleState layout substantially reduce heap churnReplacing the
Stringfields inUpdatedItemwith fixedChar<20>buffers and centralizing state storage in the sharedgModulesDocdocument eliminates a lot of per‑update heap allocation. Combined with the staticupdateOriginIdand the comment about expected write patterns, this is a good fit for the constrained ESP32 heap and the unique‑prefix property naming scheme.Also applies to: 51-56

39-41: Usingsizeof(sharedData.bands)inmemcpyis safer; consider guarding against size mismatchSwitching from an element-count constant to
sizeof(sharedData.bands)for thememcpysize is an improvement: the copy size now automatically tracks the actual storage ofsharedData.bandsin bytes and won’t silently go stale if the array type/length changes.Two optional robustness tweaks you might consider:
- If
sync.fftResultis also a fixed array, add astatic_assert(sizeof(sharedData.bands) <= sizeof(sync.fftResult), "AudioSync: fftResult smaller than sharedData.bands");near the class to catch mismatches at compile time.- Alternatively, if you want to be ultra-defensive, copy
min(sizeof(sharedData.bands), sizeof(sync.fftResult)), though that’s usually overkill on constrained MCUs.As-is, the change is correct and a clear improvement over a raw channel-count constant.

58-67: Consider making the color palette static to reduce per-instance heap usage.Since
colorwheelpaletteis never modified and contains the same constant values for all instances, declaring it asstatic const(orstatic constexprwith astd::array) would eliminate per-instance heap allocation—directly supporting this PR's ESP32 heap-optimization goals.Apply this diff to make the palette static:
- std::vector<CRGB> colorwheelpalette = { + static const std::vector<CRGB> colorwheelpalette; +}; + +inline const std::vector<CRGB> Troy1MoveEffect::colorwheelpalette = { CRGB(255, 255, 255), // White CRGB(255, 0, 0), // Red CRGB(0, 255, 0), // Green CRGB(0, 0, 255), // Blue CRGB(255, 255, 0), // Yellow CRGB(0, 255, 255), // Cyan CRGB(255, 165, 0), // Orange CRGB(128, 0, 128) // Purple - }; +};Or, for a more compact solution using
std::array:- std::vector<CRGB> colorwheelpalette = { + static constexpr std::array<CRGB, 8> colorwheelpalette = {{ CRGB(255, 255, 255), // White CRGB(255, 0, 0), // Red CRGB(0, 255, 0), // Green CRGB(0, 0, 255), // Blue CRGB(255, 255, 0), // Yellow CRGB(0, 255, 255), // Cyan CRGB(255, 165, 0), // Orange CRGB(128, 0, 128) // Purple - }; +}};Note: If using

87-87: Consider makingclientIdprivate.This method is only used internally by
transmitId. Moving it to the private section would improve encapsulation.
101-116: Consider JsonDocument pooling for heap-constrained devices.On ESP32-D0 (no PSRAM), allocating a new
JsonDocumentper transmission could contribute to heap fragmentation with large module states. The PR discussion notes ArduinoJson v7'ssizeof(JsonDocument)is small, making pooling optional. If heap pressure is observed, consider using a shared/pooled document with mutex protection.

26-37: Connectivity guard andinitlifecycle look good; confirmWLEDSync::begin()re-init behaviorThe new
if (!WiFi.isConnected() && !ETH.connected())guard plusinit = false; return;gives you a clean “no network, no work” path and ensuressync.begin()is only called once per connectivity period, which is what you want.The only thing to double‑check is the behavior of
WLEDSync::begin()across multiple calls over the device lifetime:
- With this pattern, every WiFi/ETH reconnect will re-run
sync.begin()(once).- If
begin()internally allocates sockets/buffers without fully reusing/freeing them across calls, you could slowly leak or fragment heap on ESP32, especially on D0 without PSRAM.If the library guarantees
begin()is idempotent and safe to call on reconnects, this is fine. Otherwise, consider pairinginit = falsewith an explicitsync.end()/reset (if available) when losing connectivity, or guarding re-init with an explicit “hasBegun” flag and only callingbegin()once per object lifetime.src/MoonLight/Nodes/Effects/E_MovingHeads.h (1)
349-349: LGTM! Critical fix for array initialization.The change correctly fixes a bug where only
NUM_GEQ_CHANNELSbytes were zeroed instead of the full array size. SincebandSpeedisuint16_t[NUM_GEQ_CHANNELS], the old code would have left half the array uninitialized (assuminguint16_tis 2 bytes on ESP32).src/MoonBase/Utilities.h (5)
118-118: LGTM! Clean simplification of fromJson.The one-liner constructor-based approach is idiomatic and equivalent to the previous multi-line implementation.
166-182: Good const-correctness improvements to Char operators.The changes properly handle null checks for JsonVariant/JsonString and add the missing
operator=(const String&)overload. The const reference parameters avoid unnecessary copies.
189-211: Const-correctness applied consistently across operators.The
operator+,operator+=, and comparison operators now correctly useconstqualifiers and references where appropriate.
242-242: Correct:c_str()is now const.This allows calling
c_str()on constChar<N>instances, which is the expected behavior.
389-391: Good optimization:fastDiv255is a well-known technique.This uses the multiplication-by-reciprocal trick
(x * 0x8081) >> 23which approximatesx / 255in 3-4 cycles instead of a costly division. This is commonly used in graphics/LED code for color scaling.src/MoonLight/Nodes/Effects/E_MoonModules.h (3)
81-82: Good: Usingsizeof()instead of hardcoded array size.This is safer and self-documenting. If the array sizes change, the memset will automatically adapt.
109-109: Control size now matches the array size.The
customRuleStringis declared aschar[20]on line 54, so the control limit of 20 is correct and consistent.
121-125: Signature update aligns with codebase-wide refactor.The
onUpdatesignature change toconst Char<20>&matches the pattern used in other nodes (D_VirtualDriver.h, D__Sandbox.h, E__Sandbox.h, E_MoonLight.h) as shown in the relevant code snippets.src/MoonLight/Nodes/Effects/E_MoonLight.h (6)
37-37: Critical fix: Loop index now properly initialized.This was previously flagged as a critical issue. Using an uninitialized
indexvariable caused undefined behavior when iterating through lights.
116-116: Good:frameNrnow initialized to 0.Prevents undefined behavior from using an uninitialized local variable.
264-270: Good: IP address cached to avoid repeated API calls.Caching
activeIPavoids callingWiFi.localIP()orETH.localIP()multiple times within the same loop iteration. This is both a micro-optimization and improves code clarity.
617-620: Good: Usingsizeof()for array clearing.This is safer than hardcoding the array sizes. The memset calls will automatically adapt if the array declarations change.
926-930: Signature update consistent with codebase refactor.The
onUpdatesignature change toconst Char<20>&aligns with the pattern established across other effect and driver nodes.
1122-1126: Signature update consistent with codebase refactor.Same pattern as RubiksCubeEffect - the
onUpdatesignature is correctly updated toconst Char<20>&.src/MoonBase/NodeManager.h (6)
23-23: Good:defaultNodeNamechanged to fixed-sizeChar<20>.This aligns with the PR's heap optimization goals by avoiding heap-allocated
Stringobjects. Node names are typically short identifiers that fit within 20 characters.
134-134: Good:onUpdatenow takesconst UpdatedItem&.The const reference is more efficient (avoids copy) and safer (prevents accidental modification). This aligns with the pattern in ModuleIO.h and ModuleChannels.h.
205-205: Consistent with the semantic change at line 151.Same pattern - checking for non-empty oldValue to determine if an old node existed.
249-249: Good: Usingas<const char*>()for logging.This avoids creating temporary
Stringobjects for logging purposes.
298-299: Good:loop()now explicitly overrides base class.The
overridespecifier ensures compile-time checking that this correctly overrides a virtual method. CallingModule::loop()ensures base class behavior is preserved.
151-155: The comparison change from"null"to""is not evident in the codebase—the code already consistently uses empty string semantics.After verifying the codebase, I found that
UpdatedItem.oldValue(defined asChar<20>in Module.h:28) is consistently initialized and compared using empty string""throughout the codebase, not the literal string"null".Evidence:
- In Nodes.h:145, new controls initialize
oldValue = ""- In Module.cpp:200 and Module.cpp:244,
oldValueis assigned from actual property values- In ModuleIO.h:396, the same comparison pattern is already in use:
updatedItem.oldValue == ""- Comment in Nodes.h:153 confirms: "called in addControl (oldValue = "")"
- No
"null"string comparisons exist in the repositoryThe comparison
updatedItem.oldValue != ""correctly checks whether a previous value existed before removing controls. This is the established pattern in the codebase and does not represent a semantic change.src/MoonLight/Modules/ModuleDrivers.h (3)
69-76: Good:begin()now hasoverridespecifier.The
overridekeyword provides compile-time verification that this correctly overrides the virtual method fromNodeManager. The order of operations is correct: assignnodespointer before callingNodeManager::begin().
158-159: Good: Added pre-construction logging for debugging.This log statement captures the node name, pointer address, and PSRAM status before calling the constructor chain. Useful for debugging memory allocation issues on ESP32.
179-189: Good:loop()now hasoverridespecifier.The
overridekeyword ensures compile-time verification. The method correctly delegates toNodeManager::loop()while adding module-specific initialization logic.src/MoonBase/SharedHttpEndpoint.h (2)
36-38: CORS OPTIONS handler uses different auth predicate.The CORS handler uses
IS_AUTHENTICATEDwhile the actual GET/POST handlers use_authenticationPredicate(defaulting toIS_ADMIN). This may be intentional for lighter preflight auth, but verify this is the desired behavior.
64-88: POST handler implementation looks correct.The
updateWithoutPropagation+callUpdateHandlerspattern properly separates state mutation from persistence/propagation. Returning the updated state in the response is good REST practice.src/MoonBase/SharedWebSocketServer.h (2)
33-37: LGTM!The update handler registration correctly captures the module pointer and constructs the path for transmission.
78-82: Socket cleanup properly implemented.The
onClosehandler now correctly erases the socket from_initializedSockets, preventing unbounded growth and stale entries.src/MoonLight/Nodes/Drivers/D_FastLED.h (2)
97-101: LGTM! Safe pin count calculation prevents unassigned pin access.The
nrOfPinscalculation correctly bounds the iteration to the minimum of configured and assigned pins, preventing potential out-of-bounds access. The early return when no pins are assigned is appropriate.
104-104: LGTM! Loop correctly enforces both logical and hardware pin limits.The condition properly caps iteration at the minimum of
nrOfPinsand 4 (FastLED RMT hardware limit), preventing both logical errors and hardware constraint violations.src/MoonLight/Nodes/Drivers/D_PhysicalDriver.h (3)
52-59: LGTM! Consistent pin count calculation prevents driver API misuse.The computed
nrOfPinscorrectly bounds the pin count passed toshow_parlio, ensuring the low-level driver doesn't attempt to access unassigned pins or exceed buffer boundaries.
76-83: LGTM! Safe guard prevents initialization with invalid pin configuration.The early return when
nrOfPins == 0prevents unnecessary driver initialization work and potential errors from operating with no assigned pins.
90-111: LGTM! Driver initialization and updates use accurate pin counts.The use of
nrOfPinsininitled()andupdateDriver()calls ensures the underlying driver infrastructure operates on the correct subset of assigned pins, preventing potential memory access issues or initialization errors.src/MoonLight/Layers/PhysicalLayer.h (1)
136-136: LGTM! New field enables safe pin-count tracking.The
nrOfAssignedPinsfield provides runtime tracking of actually assigned pins, enabling the derivednrOfPinscalculations in driver code to prevent out-of-bounds access. The zero initialization is a safe default.src/MoonLight/Layers/PhysicalLayer.cpp (4)
34-36: Informational comments document heap constraints and optimization goals.The comments provide useful context for understanding the memory allocation strategy on PSRAM-less boards, where heap is limited to ~60KB.
136-136: LGTM! Explicit comment clarifies memset intent.The explicit
0xFFvalue with the// UINT16_MAXcomment clarifies that eachuint16_telement will be initialized to 0xFFFF (UINT16_MAX), which is the intended sentinel value for unassigned pins.
179-189: LGTM! Critical fix: corrects loop bound to prevent array overrun.The original code used
i < sizeof(ledsPerPin), which for auint16_t[20]array would evaluate to 40 (bytes), causing iteration far beyond array bounds. The fix toi < MAXLEDPINScorrectly bounds the loop to the actual array length. The addition ofnrOfAssignedPinstracking (line 186) enables safe pin iteration in driver code.
78-78: LGTM! Cosmetic spacing adjustment.Minor formatting improvement for code readability.

98-109: Missing null check forgl.createProgram()result.
gl.createProgram()can returnnull. Lines 100-102 useprogramwithout verifying it's not null, which could cause silent failures or runtime errors.const createProgram = (gl: WebGLRenderingContext, vertexShader: WebGLShader, fragmentShader: WebGLShader): WebGLProgram => { const program = gl.createProgram(); + if (!program) { + throw new Error("Unable to create program"); + } gl.attachShader(program, vertexShader); gl.attachShader(program, fragmentShader); gl.linkProgram(program);src/MoonLight/Nodes/Effects/E_MoonLight.h (1)
115-135:LinesEffect:frameNrreinitialization prevents color cycling
frameNris declared and initialized to 0 at the start ofloop()and only incremented once at the end. Because it’s a local variable, its value is lost on each call, so:int frameNr = 0; ... int colorNr = (frameNr / layer->size.y) % 3; ... (frameNr)++;means
colorNris always 0 and the effect never rotates through the three colors.If the intent is to have a time‑evolving pattern, make
frameNrpersistent, e.g.:- void loop() override { - int frameNr = 0; + int frameNr = 0; // member of LinesEffect + + void loop() override { @@ - (frameNr)++; + frameNr++;(or declare
static int frameNrinsideloop()if you prefer a function‑local static). That will allow the color selection to advance across frames as originally designed.src/MoonBase/Module.cpp (1)
143-151: Based on my verification, I can now provide the rewritten review comment:Char<20> truncation risk is real but not currently manifesting.
Line 145 assigns
parent(aJsonString) toupdatedItem.parent[depth](aChar<20>). While parent array names in active use like"nodes"and"controls"are short, the code structure is vulnerable to truncation for any JSON key exceeding 19 characters assigned at depth 0 or 1 duringcompareRecursive(). For example,"mappingTableIndexes#"(20 chars) from ModuleMoonLightInfo would exceed the limit, though this particular module is read-only so comparisons never occur. The truncation would be silent. Consider either: (1) expandingChar<20>to a larger capacity, or (2) adding runtime validation to assert parent key lengths.

34-38: SolidEffect white loop index fix confirmedInitializing
indexto 0 in the white channel loop removes the prior undefined behavior and is the correct fix; the loop is now well‑defined for allnrOfLights.src/MoonLight/Nodes/Effects/E__Sandbox.h (1)
38-38: Bug fix already addressed.The assignment operator

15-20: Missing include forHTTP_ENDPOINT_ORIGIN_ID.The constant
HTTP_ENDPOINT_ORIGIN_IDis used at line 79 but is defined inHttpEndpoint.h, which is not included. Add the missing include to prevent compilation errors.#include <PsychicHttp.h> #include <SecurityManager.h> +#include <HttpEndpoint.h> #include <map>
89-94: Undefinedmodulesvariable and improved but incomplete path matching.
The
modulesvariable on line 90 is not declared in this file. It appears to reference an external global—add anexterndeclaration or pass it as a constructor parameter.Using
endsWith()is better thancontains(), but can still incorrectly match if one module name is a suffix of another (e.g., path/rest/moduleiowould match module named"io"). Consider matching the full path segment.+extern std::vector<Module*> modules; // Add at file scope, or pass via constructor Module* findModule(const String& path) { + String expectedSuffix = "/rest/"; for (Module* module : modules) { - if (path.endsWith(module->_moduleName.c_str())) return module; + if (path == expectedSuffix + module->_moduleName) return module; } return nullptr; }src/MoonBase/Module.cpp (1)
262-266: StaticupdateOriginIdwithout synchronization.As flagged in a previous review,
ModuleState::updateOriginIdis static and written byupdate()then read inprocessUpdatedItem(). Without synchronization, concurrent updates from different tasks could observe the wrong origin. However, the new semaphore-based flow (updateReadySem/updateProcessedSem) appears to serialize update processing, which may mitigate this in practice.src/MoonBase/SharedWebSocketServer.h (2)
101-116: JsonDocument allocated without size limit in transmitData.As noted in a previous review, allocating
JsonDocumenton the stack without size constraints can cause heap exhaustion for large module states. Consider using a shared document pool with mutex protection or pre-sizing the document.

🧹 Nitpick comments (13)

282-282: Consider making both parameters const references for consistency.The first parameter
awas changed toconst Coord3D&(good for avoiding copies), but the second parameterbremains pass-by-value. For consistency and to align with the heap-optimization goals of this PR, consider making both parameters const references.Apply this diff for consistency:
- void drawLine3D(const Coord3D& a, Coord3D b, CRGB color, bool soft = false, uint8_t depth = UINT8_MAX) { drawLine3D(a.x, a.y, a.z, b.x, b.y, b.z, color, soft, depth); } + void drawLine3D(const Coord3D& a, const Coord3D& b, CRGB color, bool soft = false, uint8_t depth = UINT8_MAX) { drawLine3D(a.x, a.y, a.z, b.x, b.y, b.z, color, soft, depth); }interface/src/routes/moonbase/monitor/monitor.ts (2)
119-123: Add input validation to prevent division by zero.If
setMatrixDimensions(0, 0)is called,getMVPMatrix()will divide by zero at line 161-162 when computingnormalizedWidth/Height. Consider clamping to minimum values.export function setMatrixDimensions(width: number, height: number) { - matrixWidth = width; - matrixHeight = height; + matrixWidth = Math.max(1, width); + matrixHeight = Math.max(1, height); }
177-177: Stale comment: value doesn't match description.The comment says "1.2 adds some padding" but the actual multiplier is
2.5. Update the comment to reflect the current value.- const cameraDistance = Math.max(distanceForHeight, distanceForWidth) * 2.5; // 1.2 adds some padding + const cameraDistance = Math.max(distanceForHeight, distanceForWidth) * 2.5; // 2.5 adds paddingsrc/MoonLight/Layers/PhysicalLayer.cpp (1)
136-136: Pin bookkeeping: consider also resettingnrOfAssignedPinsinonLayoutPreThe change to initialize
ledsPerPinwith0xFFand thewhile (i < MAXLEDPINS && ledsPerPin[i] != UINT16_MAX)loop is correct and safely bounded byMAXLEDPINS. UpdatingnrOfAssignedPins = i + 1when a new pin is assigned also looks right.To avoid stale state between layouts when you deallocate pins, it would be slightly safer to also reset
nrOfAssignedPinsalongsidememset(ledsPerPin, 0xFF, ...)inonLayoutPre()(pass 1). That guarantees any consumer relying onnrOfAssignedPinsdoesn’t see the previous layout’s pin count before the firstnextPin()call of the new layout.Also applies to: 179-188
src/MoonLight/Modules/ModuleLightsControl.h (3)
37-69:begin()wiring looks correct; clarify ModuleIO member usageCalling
Module::begin()first, logging the struct sizes, wiring the FileManager update handler, and then usingmoduleIO.addUpdateHandler(...)plus an initialreadPins()gives a clean startup path for brightness control.This class also stores a
ModuleIO* _moduleIOin the constructor but only uses the unqualifiedmoduleIOmember here and inreadPins(). If_moduleIOis truly unused, consider removing it (and possibly the constructor parameter) to save a few bytes and avoid confusion about which ModuleIO instance is authoritative.
84-134: Const-correct definition and preset guard look good; minor cleanup possibleSwitching
setupDefinitiontoconst JsonArray& rootandonUpdatetoconst UpdatedItem&aligns this module with the new const‑correct API surface. The updated preset guardif (updatedItem.oldValue != "" && !updatedItem.value["action"].isNull()) { ... }is a clearer way to skip preset application on the initial boot/default state while still reacting to user‑initiated “click”/“dblclick” actions.
Within
setupDefinition,JsonArray details = root;is no longer used and could be dropped to trim a little code and keep the definition focused.Also applies to: 137-207
238-284: Preset loop: good removal ofrunInAppTask; consider staticJsonDocumentHaving
loop()callModule::loop()first and then handlingpresetLoopdirectly (instead of pushing lambdas intorunInAppTask) is a solid improvement for both clarity and heap stability on D0 boards.The only remaining heap touchpoint here is the local
JsonDocument doc;used whenpresetLoopis active. Given this runs relatively infrequently and is gated bypresetLoop, it’s probably fine; but if you want to fully avoid dynamic JSON allocations in this path, you could switch to a smallStaticJsonDocument<N>or a shared memberJsonDocumentwith reserved capacity andclear()it before reuse.src/MoonLight/Nodes/Effects/E_MoonLight.h (1)
264-271: IP caching in ScrollingTextEffect is fine; offline case still yields.0Using
IPAddress activeIP = WiFi.isConnected() ? WiFi.localIP() : ETH.localIP();and thentext.format(".%d", activeIP[3]);is a reasonable simplification and avoids repeatedlocalIP()calls.Just be aware that when neither interface has a valid IP, this will show “.0”. If you ever want a more explicit “offline” indication in that preset, you could gate this on
sharedData.connectionStatusor checkactiveIP == INADDR_NONEand fall back to a different text.src/MoonLight/Nodes/Effects/E__Sandbox.h (1)
35-41: Missingoverridespecifier ononUpdate.Other effect classes declare
onUpdatewithoverride(seeE_MoonLight.hlines 925, 1121). This sandbox template should also includeoverrideto ensure it correctly overrides the base class method and catches signature mismatches at compile time.- void onUpdate(const Char<20>& oldValue, const JsonObject control) { + void onUpdate(const Char<20>& oldValue, const JsonObject control) override {src/MoonLight/Modules/ModuleMoonLightInfo.h (1)
128-130: Unused loop variableindexP.The variable
indexPis declared but never used inside the loop body—onlynrOfMoreLightsis incremented. Consider using a simpler counting approach to avoid the unused variable warning.case m_moreLights: - for (uint16_t indexP : layer->mappingTableIndexes[map.indexes]) { - nrOfMoreLights++; - } + nrOfMoreLights += layer->mappingTableIndexes[map.indexes].size(); break;If
mappingTableIndexes[map.indexes]doesn't have a.size()method, you can suppress the warning with:- for (uint16_t indexP : layer->mappingTableIndexes[map.indexes]) { + for ([[maybe_unused]] uint16_t indexP : layer->mappingTableIndexes[map.indexes]) {src/MoonBase/SharedHttpEndpoint.h (1)
49-49: Emptybegin()method.The
begin()method is empty. If no initialization is needed, consider removing it or adding a comment explaining why it exists (e.g., for API consistency with other shared components).src/MoonBase/Modules/ModuleIO.h (1)
391-412: Good pattern: Deferring heavy work to main loop.The
newBoardIDqueue mechanism correctly addresses the stack depth issue that caused crashes duringsetBoardPresetDefaults. By deferring the preset application toloop(), the update callback completes quickly, preventing stack exhaustion during large state updates.However, consider using
std::atomic<uint8_t>fornewBoardIDsince it could theoretically be written from a WebSocket handler task while being read in the main loop, though in practice the semaphore-based flow likely serializes access.src/MoonBase/Module.h (1)
23-29: UpdatedItem Char<20> refactor looks good; comments are slightly misleading.Using
Char<20>here is a solid heap win versusStringand still comfortably covers all known property names and values (and then some, based on prior length analysis). The only nit is that the inline sizing comments (// 24 -> 2*20,// 32 -> 16 -> 20,// 8->16->4) no longer match the actual field sizes and history, which can confuse future readers.Consider either updating or removing those numeric comments; the code itself is fine.
Based on learnings, the current Char<20> capacity is more than sufficient for existing property names.

src/MoonLight/Layers/VirtualLayer.h (3)
30-33: Good documentation of heap constraints.The comments clearly document the memory constraints (60 KB heap, 30 KB max allocation) for ESP32 boards without PSRAM, providing valuable context for the optimization effort.
63-68: Clear explanation of mapping architecture.The comments effectively document the purpose and constraints of the virtual-to-physical light mapping structures, including the 12288 LED target for non-PSRAM boards.
72-73: I'll help you verify that the new size-tracking fields are properly maintained throughout the codebase. Let me start by exploring the repository structure and examining the relevant implementation files.
<function_calls>
First, find the VirtualLayer implementation file
fd -t f "VirtualLayer.(cpp|cc|h)"
</function_calls>Let me search for the implementation file more broadly:
<function_calls>
Find all VirtualLayer files
find . -name "VirtualLayer" -type f 2>/dev/null | head -20
</function_calls>Now let me search for assignments to the new tracking fields:
<function_calls>
#!/bin/bashSearch for assignments to mappingTableSizeUsed
echo "=== Assignments to mappingTableSizeUsed ==="
rg -n 'mappingTableSizeUsed\s*=' --type=cpp --type=h -C2echo ""
echo "=== Assignments to mappingTableIndexesSizeUsed ==="
rg -n 'mappingTableIndexesSizeUsed\s*=' --type=cpp --type=h -C2
</function_calls>Let me also search for modifications to the vectors themselves:
<function_calls>
#!/bin/bashSearch for modifications to mappingTable
echo "=== Operations on mappingTable ==="
rg -n 'mappingTable\s*.' --type=cpp --type=h -C1 | head -100echo ""
echo "=== Operations on mappingTableIndexes ==="
rg -n 'mappingTableIndexes\s*.' --type=cpp --type=h -C1 | head -100
</function_calls>Let me look at the VirtualLayer.h header file to understand the class structure better:
<function_calls>
Find and display VirtualLayer.h
rg -l "VirtualLayer" --type=h | grep -i virtual
Also get its line count to see if we can read it
fd -t f -e h | xargs grep -l "mappingTableSizeUsed" 2>/dev/null
</function_calls><function_calls>
Show the file with mappingTableSizeUsed
fd -t f -name ".h" -o -name ".cpp" | xargs grep -l "mappingTableSizeUsed" 2>/dev/null
</function_calls><function_calls>
Search more broadly for these fields
rg "mappingTableSizeUsed" -C3
</function_calls><function_calls>
Search for VirtualLayer files
git ls-files | grep -i virtual
</function_calls><function_calls>
Display the full file if it exists
git ls-files src/MoonLight/Layers/VirtualLayer.h && cat src/MoonLight/Layers/VirtualLayer.h
</function_calls><function_calls>
Search for the cpp file
git ls-files src/MoonLight/Layers/VirtualLayer.cpp && wc -l src/MoonLight/Layers/VirtualLayer.cpp
</function_calls><function_calls>
Get the full implementation file
git ls-files src/MoonLight/Layers/VirtualLayer.cpp && cat -n src/MoonLight/Layers/VirtualLayer.cpp
</function_calls><function_calls>
Check what's in the src/MoonLight/Layers directory
git ls-files src/MoonLight/Layers/ 2>/dev/null | head -20
</function_calls><function_calls>
Check if the file path exists at all
ls -la src/MoonLight/Layers/ 2>/dev/null || echo "Path does not exist"
Try broader search
find . -path "/Layers/" -type f 2>/dev/null | head -20
</function_calls><function_calls>
Let's see what's in the repo root
git ls-files | head -30

158-185: LGTM!The normalized dimension scaling logic correctly handles varying matrix aspect ratios by normalizing to the larger dimension and computing appropriate camera distance for both vertical and horizontal fit.
82-96: LGTM!The shader creation function properly handles the null case from
gl.createShader()and throws descriptive errors for both creation and compilation failures.src/MoonLight/Layers/PhysicalLayer.cpp (1)
34-37: Heap notes and LED capacity comment are consistentThe new heap-optimization comments and the updated
lights.maxChannels = 4096 * 3;comment now accurately describe the current 4096‑LED constraint on non‑PSRAM ESP32 boards. No functional issues here; this is good documentation of the heap trade‑off.Also applies to: 44-44
src/MoonLight/Nodes/Effects/E_MoonLight.h (4)
617-621: FreqSawsEffect array initialization viasizeofis robustSwitching the band arrays’ initialization to:
memset(bandSpeed, 0, sizeof(bandSpeed)); memset(bandPhase, 0, sizeof(bandPhase)); memset(lastBpm, 0, sizeof(lastBpm)); memset(phaseOffset, 0, sizeof(phaseOffset));is correct and more future‑proof than hard‑coded element counts. No issues here.
925-930: RubiksCubeEffectonUpdateoverride matches new APIThe updated signature
void onUpdate(const Char<20>& oldValue, const JsonObject control) overridealigns this effect with the new base API and only usescontrol["name"], which is fine. LeavingoldValueunused here is acceptable for an override.
1122-1126: ParticlesEffectonUpdateoverride is consistent with new typesSimilarly, the new

operator=acceptingChar<M>of any size enables seamless assignment between different-sizedCharinstances while safely truncating when needed.
197-200: Explicit conversion operator is safer.Making
operator const char*()explicit prevents unintended implicit conversions that could lead to dangling pointer issues or unexpected behavior in overload resolution.
211-215: Correct value semantics for operator+.Returning a new

totalRunTimeto 1 ensures the percentage calculation at line 99 cannot divide by zero, even ifuxTaskGetSystemStatefails to populate it.
99-99: Integer overflow fix correctly applied.The 64-bit arithmetic with
100ULL * ts->ulRunTimeCounterprevents the overflow issue identified in previous reviews.
107-107: Based on my verification, I've found important information:Key Findings:
- No explicit FreeRTOS runtime stats configuration is present in the repository. ESP-IDF 5.1+ has runtime stats disabled by default.
- Timer source ambiguity: The code divides by 1,000,000 (assuming 1 MHz ESP Timer), but if configured to use CPU clock (80-240 MHz), this divisor would be completely incorrect.
- Documentation mismatch: The project's own documentation (
docs/moonbase/tasks.md) describes the runtime field as "cpu cycles", yet the code treats it as seconds by dividing by 1,000,000.- No configuration verification: Without seeing the actual build configuration (sdkconfig), there's no way to confirm which timer source is active or if runtime stats are even enabled.
The review comment's concern is valid and substantial. The assumption cannot be verified from the codebase alone.
Verify FreeRTOS runtime counter timer source and enabled status.
The division by 1,000,000 assumes
ulRunTimeCounteris in microseconds (1 MHz ESP Timer source). This requiresCONFIG_FREERTOS_GENERATE_RUN_TIME_STATS=yandCONFIG_FREERTOS_RUN_TIME_STATS_CLK=ESP_TIMER. If the project usesCPU_CLOCKinstead, the divisor should be the CPU frequency (80–240 MHz), not 1,000,000. Additionally, the documentation describes this field as "cpu cycles", which contradicts the seconds conversion. Confirm the actual FreeRTOS configuration in your build (check sdkconfig or enable via menuconfig) and update the divisor or documentation accordingly.src/MoonLight/Modules/ModuleChannels.h (3)

Potential null assignment to non-nullable types.
gl.createBuffer() returns WebGLBuffer | null per WebGL spec. On lines 63 and 70, the return value is assigned directly to non-nullable variables without null checks. If buffer creation fails (e.g., GPU resource exhaustion), this will cause runtime errors when the buffers are used in updateScene().
Consider adding null checks or restoring nullable types with guards:
-let positionBuffer: WebGLBuffer;
-let colorBuffer: WebGLBuffer;
+let positionBuffer: WebGLBuffer | null = null;
+let colorBuffer: WebGLBuffer | null = null;Then guard usage in updateScene:

🤖 Prompt for AI Agents
In interface/src/routes/moonbase/monitor/monitor.ts around lines 9-11 (and
noting buffer assignments at ~19, 63, 70), the code assigns the results of
gl.createBuffer() to non-nullable WebGLBuffer variables which can be null per
the WebGL spec; change the variable declarations to allow null (WebGLBuffer |
null), check the return values after each gl.createBuffer() call and handle
failure (log and early return or throw), and add null guards at the start of
updateScene (e.g., if (!gl || !positionBuffer || !colorBuffer) return;) so no
nullable buffer is used without verification.

The commented-out updateControl call should be restored — it performs essential pointer synchronization that onUpdate does not provide.
The evidence confirms your concern:
-
updateControldoes critical work: It dereferences pointers from the JSON control and writes values directly to variable memory locations (lines 27-28, 31-32 in Nodes.cpp). This is irreplaceable. -
onUpdateis not a replacement: It's a virtual function with an empty default implementation in the base Node class (Nodes.h:156). While subclasses can override it for custom logic, it performs no pointer synchronization by default. -
The design intent confirms the bug: The comment at line 153 states
updateControlis "called in addControl (oldValue = "")"—explicitly indicating it should handle new control initialization. The current code violates this. -
New controls remain uninitialized: When
newControl == true, the code now skipsupdateControlentirely and calls only the emptyonUpdate, leaving variables at uninitialized memory addresses until the next update.
This line should be uncommented:
updateControl(oldValue, control);🤖 Prompt for AI Agents
In src/MoonBase/Nodes.h around lines 143-147, the commented-out call to
updateControl(oldValue, control) must be restored because updateControl performs
necessary pointer synchronization for new controls; uncomment that call so
updateControl(oldValue, control) runs before onUpdate(oldValue, control)
(keeping the existing oldValue initialization) to ensure variables are
initialized immediately when newControl is true.

Are you sure about
The commented-out updateControl call should be restored — it performs essential pointer synchronization that onUpdate does not provide.
Because addControl just adds the variable at class create time and the variable already contains the default value so updateControl would do the same.

@ewowi, you raise a very good point. Let me reconsider the logic here.

Length of output: 452
@ewowi, you're absolutely right, and I apologize for the confusion. My initial analysis was incorrect.
Looking at the evidence more carefully:
-
In the
newControlpath withinaddControl:- The variable already contains its default value when passed to
addControl control["value"] = variablecopies that existing default value into the JSON- The variable and
control["value"]are identical at this point
- The variable already contains its default value when passed to
-
What
updateControldoes:- It simply reads
control["value"]and writes it to the memory address atcontrol["p"] - In the
newControlcase, this would write the same value the variable already has (a no-op)
- It simply reads
-
The smoking gun - a comment in
updateControlitself (Nodes.cpp:19):// if (oldValue == "") return; // newControl, value already setThis explicitly confirms that when
oldValueis empty (thenewControlcase), the value is already set andupdateControlwould be redundant.
Conclusion: The change to comment out updateControl and call only onUpdate is correct. The onUpdate call allows nodes to perform custom initialization logic when controls are created, while avoiding the redundant write-back that updateControl would perform.
Thank you for catching my error! 🐰

-
src/MoonBase/Nodes.h | snippet around updateControl usage in addControl
-
Context: Inside Node::addControl, when a new control is created or an existing one is updated, the code previously called updateControl(...) and now uses onUpdate(...) for per-node handling. This snippet shows the portion that sets up the control, and how an oldValue and control object are passed to the handler.
-
Full excerpt:
// if control already exists only update it's pointer
JsonObject control;
for (JsonObject control1 : controls) {
if (control1["name"] == name) {
// EXT_LOGD(ML_TAG, "%s t:%s p:%p ps:%d", name, type, pointer, sizeof(ControlType));
control1["p"] = pointer;
control = control1; // set control to the found one

-
src/MoonBase/NodeManager.h | how updateControl is invoked when a control value changes
-
Context: When a node's control value changes (UI/edit), NodeManager locates the corresponding Node and calls the Node's updateControl with the previous value and the JsonObject describing the control. It then calls the node's onUpdate for additional handling.
-
Summary description:
- In the onUpdate handler for nodes[i].controls[j].value, NodeManager finds the NodeClass for updatedItem.index[0].
- It then calls nodeClass->updateControl(updatedItem.oldValue, nodeState["controls"][updatedItem.index[1]]);
- It follows with nodeClass->onUpdate(updatedItem.oldValue, nodeState["controls"][updatedItem.index[1]]);
- Finally, it calls nodeClass->requestMappings() to propagate any needed UI/physical changes.
-
Relevant excerpt (summary):
else if (updatedItem.parent[1] == "controls" && updatedItem.name == "value" && updatedItem.index[1] < nodeState["controls"].size()) { // nodes[i].controls[j].value
...
Node* nodeClass = (*nodes)[updatedItem.index[0]];
if (nodeClass != nullptr) {
nodeClass->updateControl(updatedItem.oldValue, nodeState["controls"][updatedItem.index[1]]);
nodeClass->onUpdate(updatedItem.oldValue, nodeState["controls"][updatedItem.index[1]]); // custom onUpdate for the nodenodeClass->requestMappings();} else { ... }
}

@coderabbitai, we created 4 new classes: SharedEventEndpoint, SharedFSPersistence, SharedHttpEndpoint and SharedWebSocketServer which are shared versions of EventEndpoint, FSPersistence, HttpEndpoint and WebSocketServer . Instead of duplicating the code from the original classes, could we redesign the Shared classes to use the original classes, or by inherit from them, or have them as Shared class variables (there was a name for this, which I forgot - it's even a design pattern if I am right, maybe you know what I mean) |

#endifBenefits of This Approach✅ Zero code duplication - reuses original template implementations Design Pattern ExplanationThis is the Composition pattern (also called "has-a" or "contains-a"):

Memory ComparisonCurrent Shared Classes (duplicated code):
Composition Approach:
Result: Nearly identical memory usage, but with zero code duplication! Would you like me to generate a complete patch applying this refactoring to all four Shared classes? |

Regarding
No no no! This is not what we should want because this brings us back at Square 1 , with even a worse solution! (Storing them in the Module class was more elegant). So we need one instance of each original class, not more. The shared class adds logic to find out for which module we handle the router functionality . The only thing I try to avoid is to rewrite the code for each action again |

Tip For best results, initiate chat on the files or code changes. @ewowi, you're absolutely right! 🐰 I lost focus - we need ONE instance of each class, not 15! Let me fix this. The problem: The original template classes are designed with a single ✅ Solution: Extract Common Logic into Utility FunctionsWe can extract the request handling logic into shared utility functions that both the original template classes AND the Shared classes can use: New Utility File: lib/framework/EndpointHelpers.h#ifndef EndpointHelpers_h
#define EndpointHelpers_h
#include <PsychicHttp.h>
#include <StatefulService.h>
namespace EndpointHelpers {
// Shared HTTP GET handler logic
template <class T>

PsychicJsonResponse response = PsychicJsonResponse(request, false, bufferSize);
JsonObject jsonObject = response.getRoot();
service->read(jsonObject, reader);
return response.send();

if (outcome == StateUpdateResult::ERROR) {
return request->reply(400);

if (outcome == StateUpdateResult::CHANGED) {
service->callUpdateHandlers(originId);
}
// Return updated state
PsychicJsonResponse response = PsychicJsonResponse(request, false, bufferSize);
JsonObject responseObj = response.getRoot();
service->read(responseObj, updater);
return response.send();
}
// Shared WebSocket transmit logic

};Benefits✅ ONE instance of each Shared class (memory goal achieved) Does this approach match what you had in mind? We maintain the single-instance architecture while eliminating code duplication through shared utilities! 🐰 |
@CodeRabbit-ai can you analyze memory usage and suggest ways to reduce heap usage on ESP32?
