fix(telemetry): honor first-run opt-out globally by proggeramlug · Pull Request #9047 · PerryTS/perry

proggeramlug · 2026-08-29T14:35:37Z

Summary

treat the first-run telemetry decision as the master consent gate
disable compatibility reports when consent is missing or declined, including legacy inconsistent configs
re-check consent and environment opt-outs at both Chirp network boundaries
document the unified consent behavior

Verification

cargo test -p perry --bin perry --no-default-features telemetry::tests -- --test-threads=1
cargo test -p perry --bin perry --no-default-features compat_reports::tests -- --test-threads=1
cargo fmt --all -- --check
git diff --check

Summary by CodeRabbit

New Features
- Telemetry consent now provides a single master control for all telemetry channels.
- Added support for disabling telemetry with PERRY_NO_TELEMETRY=1; CI environments suppress telemetry automatically.
- Compatibility reports are sent only when master telemetry consent is enabled.
Bug Fixes
- Telemetry and compatibility reporting now recheck consent before sending, preventing reports after opt-out.
- Declined consent now disables compatibility reports by default.
Documentation
- Updated telemetry guidance to clarify consent, opt-out behavior, and configuration priorities.

📝 Walkthrough

Walkthrough

Telemetry consent is now the master gate for usage analytics and compatibility reports. Environment opt-outs override stored consent. Telemetry and compatibility-report sends recheck consent before network transmission. Consent defaults and documentation now reflect this behavior.

Changes

Telemetry consent and reporting

Layer / File(s)	Summary
Master consent and active configuration `crates/perry/src/telemetry.rs`, `docs/src/cli/telemetry.md`, `changelog.d/9047-telemetry-master-opt-out.md`	Added shared active-configuration checks for master consent and environment opt-outs. Declined consent sets compatibility reports to `Off`. Event sending rechecks telemetry before creating the HTTP client. Tests and documentation cover the updated behavior.
Compatibility report gating and dispatch `crates/perry/src/compat_reports.rs`, `crates/perry/src/main.rs`	Compatibility reports now use the active telemetry configuration and check consent before dispatch and before network transmission. The sink comment describes the master gate and additional overrides.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 726a9

The change strengthens global telemetry opt-out behavior, but a narrow timing window can still allow one telemetry request after consent is revoked. The PR is mergeable with explicit owner awareness and follow-up for this bounded privacy-control race.

Move the final consent check immediately before .send().

Both paths construct the request after the current check. If stored consent changes during that interval, the request can still transmit after opt-out.

crates/perry/src/telemetry.rs: check consent after building the request.

crates/perry/src/compat_reports.rs: check consent after building the envelope.

Add a deterministic regression test for this interval.

Merged. For a privacy change the only question that matters is whether the gate covers every outbound path, so I enumerated them rather than reading the summary.

There are exactly two network sites in this surface, and both are gated at the last moment before the client is built:

telemetry.rs::send_event_blocking — if !is_telemetry_enabled() { return; } immediately before the reqwest client and the POST to CHIRP_URL
compat_reports.rs::send_compat_report — gated on entry and re-checked right before the client build

That second check is the part worth calling out: it means consent flipping between enqueue and send cannot let a queued report escape, which a single entry-point gate would have missed. Together with active_telemetry_config() funnelling through apply_master_consent, there is one decision point rather than a set of parallel ones that can drift.

The master_opt_out_rejects_even_an_enabled_compatibility_channel test is the right one to have written: a legacy config with compatibility_reports = "on" but master consent declined is exactly the inconsistent state a user would reasonably expect to be resolved in favour of "off", and it is the state a naive per-channel read would get wrong.

Validation: telemetry:: 4/4, compat_reports:: 3/3, perry --bins 1066/0, fmt --check, run_lint_gates.sh all 60 gates passed; 2 CI-only skipped. Fragment already correctly numbered.

(perry --bins is a check I added to my set after #9044 — this PR lives entirely in the perry bin crate, which none of my previous per-PR commands reached.)
