Filters: fail-closed 9 s deadline for iOS log/network/breadcrumb and Android breadcrumb - #160
Conversation
…Android breadcrumb The iOS SDK has no timeout for the log, network or breadcrumb filters, and the Android SDK has none for breadcrumbs, so a JS callback that never settled left its request (and the event it retains) pending for the life of the process. The bridges now arm a 9 s deadline, the same number the Android log and network bridges forget at, that drops the item and removes the request; a late reply is a no-op. Never passes the original through. Not fixable here: the Android breadcrumb provider never recycles its pooled entry (not on a null answer either), SDK-side.

… wording - iOS: one helper (BGSRNArmPendingFilterDeadline / BGSRNDropPendingFilter) serves all three filters and is unit-tested with a fake decision block (fail closed, once only); the module call sites and reply paths are thin callers of it. The timer is cancelled when a reply takes the request. - Android: Pending.deadline is volatile. - Docs say precisely what each platform does (bridge drops at 9 s on iOS; Android log/network bridges stop waiting at 9 s, the SDK drops at 10 s). 🤖 Generated with [Claude Code](https://claude.com/claude-code)

Claude finished @krassx's task in 1m 1s —— View job Code review: PR #160, fail-closed 9 s filter deadlinesI reviewed the whole diff and read the surrounding code in FindingsNo P0–P2 issues found, so I posted no inline comments. I tried to break it along these lines, and each held up:
P3, no action needed. The iOS P3, maintainability. Cosmetic. A few doc comments were re-wrapped badly:
Behaviour change, already stated in the PR. An answer later than 9 s is now dropped on iOS log/network/breadcrumb and Android breadcrumb. Because that is a visible change for slow async filters, it's worth a CHANGELOG or release-notes line. I didn't see one in the diff. Known gap, also stated in the PR. The Android breadcrumb provider never recycles its pooled entry. That needs a fix in bugsee-android. Please keep the SDK follow-up tracked, since 40 hung or null-answered crumbs can exhaust the pool. Test notes.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winEnforce the deadline when taking a pending filter.
If the expiration block waits behind work on its queue, a JavaScript reply received after nine seconds can still pass through
BGSRNTakePendingFilter. The network, log, and breadcrumb reply methods then apply the reply and call the SDK decision block. This violates the documented fail-closed deadline.Record a monotonic expiration time when arming the request. At the shared take boundary, remove expired items, call their decision with
nil, and returnnil. This fixes all three filter paths without relying on the expiration block running on time.Suggested fix

Fixes #136
Problem
A JS filter callback that never settles left its request pending for the process lifetime wherever the SDK has no deadline of its own. Verified against Android SDK v7.4.2 and iOS SDK 7.0.0-beta7:
Change
nil(drop). One shared helper (BGSRNFilterDeadline) with unit tests using a fake decision block (fail closed, once only, timer cancelled on reply).BreadcrumbFilterBridgegets the same 9 s fail-closed deadline (injectable scheduler, tested).Behaviour change
Answers later than 9 s are now dropped on iOS log/network/breadcrumb and Android breadcrumb. The iOS breadcrumb SDK deliberately supports late answers, and the iOS network/log SDK would record them; a slow async filter (>9 s) that used to record now drops. This is the fail-closed behaviour #136 asks for.
Release note
Not fixable here (SDK follow-up)
The Android breadcrumb provider never recycles its pooled entry, even when the filter answers
null(doLogBreadcrumb(null)returns). The wrapper deadline frees the wrapper's pending request but the pooled entry stays held for the session. That needs a fix in bugsee-android.Tests
Both platforms refuse a reply once the deadline has passed even if the timer ran late (monotonic expiry per request). jest 2203 pass; lint/typecheck clean; Android
