…e, Per-proc throttling in Reflex, STALE support
… topic (/eee/metrics)
📝 WalkthroughWalkthroughSystem renamed from "Vital Circulatory System (VCS)" to "Semantic Cognitive System (SCS)" throughout the changelog. New logging infrastructure added with gzip-enabled rotating file handlers and batch ledger persistence. Metrics publishing plugin introduced alongside stale module detection, publish throttling, and enhanced health query reporting in the ROS bridge. Changes

There was a problem hiding this comment.
When the queue hits BATCH_SIZE, the worker thread calls _flush_ledger_batch() while holding _ledger_lock. _flush_ledger_batch() immediately tries to acquire the same non‑reentrant lock again, which deadlocks the logging thread the moment a batch fills. That stops further log processing and can stall shutdown. This only happens under bursty logging that reaches the batch threshold, but that’s exactly when batching is needed. Consider releasing the lock before flushing, or refactor _flush_ledger_batch() to assume the caller already holds the lock (or use an RLock).

In `@AuRoRA/src/scs/scs/CHANGELOG.rst`:
- Around line 7-8: Update the system description sentence in CHANGELOG.rst by
replacing the plural "feedbacks" with the correct uncountable noun "feedback" in
the string "**Description:** This system is the
thinking/reasoning/cognitive/guardrail, basically the command centre, of AGi
robots, that receive inputs from users, environments and sensors, and provides
feedbacks to different systems in the robots and to users." so it reads "...and
provides feedback to different systems in the robots and to users."
- Around line 66-69: Update the roadmap section heading and any matching
references from "Core VCS Architecture" to "SCS" for consistency; locate the
heading text "Core VCS Architecture" in CHANGELOG.rst and replace it with "SCS",
and scan the surrounding lines for other occurrences of "VCS" within that
section and update them accordingly to "SCS".
- Around line 12-14: The nested bullet uses "* -" which breaks RST rendering;
update the list under the "Add the following modules to Igniter:" entry so child
items are indented and use proper RST bullets (e.g., indent the module lines and
use "-" or "*" consistently), replacing the "* - Bio-Logic Clock: ..." and "* -
Memory: ..." lines with properly indented child bullets; edit the lines in
CHANGELOG.rst near the Igniter entry so the top-level line stays as "Add the
following modules to Igniter:" and the two module descriptions are indented
beneath it as nested bullets (keeping the same text for the module names and
descriptions).
- Around line 30-37: Fix the typos in the CHANGELOG entry: change "Awarenes
sPlugin" to "Awareness Plugin" in the line that begins "Added Awarenes sPlugin
to bridge EEE to ROS 2 rosout" (locate by that phrase), and remove the extra
space after "gzip," in the line that starts "Add File rotation + gzip, Batch
Ledger inserts..." so it reads "gzip, Batch Ledger inserts, ...".
In `@AuRoRA/src/scs/scs/eee.py`:
- Around line 35-52: The doRollover implementation in GzipRotatingFileHandler
skips compressing the oldest rotated file because the loop uses
range(self.backupCount - 1, 0, -1) and never targets the .{backupCount} file;
update doRollover to explicitly target and compress the oldest backup
(baseFilename + f".{self.backupCount}") or change the loop to include
self.backupCount, check existence, gzip it to .gz using gzip and
shutil.copyfileobj, then unlink the original; reference
GzipRotatingFileHandler.doRollover, RotatingFileHandler, self.backupCount and
self.baseFilename when making the change.
- Around line 231-244: The code holds EEEAggregator._ledger_lock while calling
EEEAggregator._flush_ledger_batch(), causing a deadlock because threading.Lock
is not reentrant; modify _start_ledger_flush (flush_loop) so it does not call
_flush_ledger_batch() while holding EEEAggregator._ledger_lock (release the lock
before invoking _flush_ledger_batch()), and likewise update the batch-full path
that currently calls _flush_ledger_batch() inside the _ledger_lock context to
instead perform the flush after exiting the lock; keep the Timer setup
(threading.Timer, daemon, start) unchanged but ensure actual flush calls occur
outside the _ledger_lock scope.

Correct the plugin name typo and extra spacing.
“Awarenes sPlugin” and the double space after “gzip,” should be fixed for clarity.

Compress the actual oldest rotated backup.
RotatingFileHandler keeps backups numbered 1 to backupCount, where .backupCount is the oldest. The current loop (range(self.backupCount - 1, 0, -1)) checks .1 through .(backupCount-1) but skips the oldest file .backupCount. Directly compress .backupCount instead.
🛠️ Proposed fix
- if self.backupCount > 0:
- # Find the oldest .1 file (or whichever is now the "extra" one)
- log_path = Path(self.baseFilename)
- for i in range(self.backupCount - 1, 0, -1):
- old_file = log_path.parent / f"{log_path.name}.{i}"
- if old_file.exists():
- with open(old_file, 'rb') as f_in:
- with gzip.open(f"{old_file}.gz", 'wb') as f_out:
- shutil.copyfileobj(f_in, f_out)
- old_file.unlink() # Delete uncompressed
- break

In `@AuRoRA/src/scs/scs/eee.py` around lines 35 - 52, The doRollover
implementation in GzipRotatingFileHandler skips compressing the oldest rotated
file because the loop uses range(self.backupCount - 1, 0, -1) and never targets
the .{backupCount} file; update doRollover to explicitly target and compress the
oldest backup (baseFilename + f".{self.backupCount}") or change the loop to
include self.backupCount, check existence, gzip it to .gz using gzip and
shutil.copyfileobj, then unlink the original; reference
GzipRotatingFileHandler.doRollover, RotatingFileHandler, self.backupCount and
self.baseFilename when making the change.

Deadlock risk: _flush_ledger_batch() acquires _ledger_lock while it's already held.
threading.Lock is non-reentrant. The code calls _flush_ledger_batch() in two places while already holding _ledger_lock:
- Lines 231-244:
_start_ledger_flush()holds the lock, thenflush_loop()immediately calls_flush_ledger_batch() - Lines 437-441: the batch-full path calls
_flush_ledger_batch()inside the lock context
Both will deadlock. Release the lock before calling _flush_ledger_batch().

In `@AuRoRA/src/scs/scs/eee.py` around lines 231 - 244, The code holds
EEEAggregator._ledger_lock while calling EEEAggregator._flush_ledger_batch(),
causing a deadlock because threading.Lock is not reentrant; modify
_start_ledger_flush (flush_loop) so it does not call _flush_ledger_batch() while
holding EEEAggregator._ledger_lock (release the lock before invoking
_flush_ledger_batch()), and likewise update the batch-full path that currently
calls _flush_ledger_batch() inside the _ledger_lock context to instead perform
the flush after exiting the lock; keep the Timer setup (threading.Timer, daemon,
start) unchanged but ensure actual flush calls occur outside the _ledger_lock
scope.
