Review finding. _sweep_debris globbed only *.partial. The *.corrupt files this PR writes when a batch cannot be decoded are matched by no glob in the module, so they accumulated for the life of the install. Collected on the expiry window rather than the stale window, deliberately: a quarantined batch is the only remaining evidence of events that could not be delivered, so someone chasing a report of missing telemetry has to be able to find a recent one. Debris keeps the short window; it carries nothing. One test, asserting both halves: a recent quarantine survives and an expired one does not.

"""Usage telemetry for Mem0 agent plugins.
|
|
|
|
Events are linked to your Mem0 account email when an API key is configured, and
|
|
to a random per-machine id otherwise. Not anonymous — the Python SDK and CLI
|
|
attribute the same way.
|
|
|
|
Hooks run on a 3-6 second budget and fire on every tool call, so recording never
|
|
touches the network: `record` appends one JSON line to a local spool and returns.
|
|
A detached `python3 telemetry.py` drains the spool in one batched PostHog request,
|
|
started once per session and again from the flush worker that is already detached.
|
|
|
|
Pure stdlib, matching the rest of the plugin. Opt out with MEM0_TELEMETRY=false.
|
|
|
|
Never sends prompts, memory text, queries, file paths, repository names, or API
|
|
keys: only event names, durations, counts, coarse outcomes, and repo/session
|
|
identifiers hashed with a random per-install salt.

|
|
lived in the identity dict:
|
|
|
|
- Hooks are short-lived separate processes firing on every tool call, and
|
|
people run more than one agent window. A read-modify-write would let each
|
|
process mint its own salt, so one repository would hash several ways in the
|
|
window before a writer won.
|
|
- resolve_distinct_id holds a copy of the identity dict across a network call
|
|
to /v1/ping/, so whichever write landed second erased the other's key —
|
|
losing either the salt (repo_hash changes mid-stream) or the email (a
|
|
second $identify, splitting the person).
|
|
- Touching the identity file from record() would create it, and is_first_run

|
keys off that file, so recording an event would silently suppress the
|
|
install event.
|
|
|
|
Published atomically, and there is deliberately no derived fallback. Creating

the file with O_CREAT|O_EXCL and then writing into it leaves a window where
|
|
the file exists and is empty, and a concurrent hook that reads it in that
|
|
window gets nothing. Falling back to a digest of the path would hand that
|
|
process a salt an attacker can compute, memoized for its whole run, which is
|
|
the privacy control this function exists to provide silently turning itself

off under load. The salt is written to a private temp file first and linked

into place, so the name either does not exist or already has the full value.
