From 35b869944e206ba1742c9b8d7d2329fd0db2f1e0 Mon Sep 17 00:00:00 2001 From: Jason Ross Date: Sun, 5 Jul 2026 17:46:48 -0500 Subject: [PATCH] feat(reporting): PII-free latency breadcrumbs on the message-open path (#358) Adds AppLog breadcrumbs to the message-open path so a debug report can show where the reader's spinner time goes: - ImapClient.withStore: per-op connect vs. work timing plus a live connect-per-op connection gauge (issue #125's provider-ceiling context). - fetchBodyMarkingSeen: select/body/flag phase timings plus PII-free size counts (RFC822 size, body chars, attachment count). - MailRepositoryImpl.openMessage: end-to-end open latency plus the cached-vs-fetched branch, keyed by accountLogRef and logSafeFolderLabel. - ReaderViewModel: spinner-to-ready latency, split success vs. failure. All breadcrumbs are PII-free: accounts are logged via the existing accountLogRef hash, folders via the existing logSafeFolderLabel allowlist, and everything else is sizes/durations/booleans only. Fixes the 4 unit-test classes that exercise this code without mocking android.util.Log (a throwing stub under plain JVM tests): mockkStatic(Log) is now installed in MailRepositoryImplCoverageTest, ImapClientBackfillTest, ImapFolderOpenLatencyTest, and ReaderViewModelActionsTest, following the existing MailBackfillerTest/ImapClientTest conventions. detekt.yml gains two more ForbiddenImport excludes for the newly Log-importing test files.
