From cc39bb819079f0bfdcca23039f121f0c056c0aee Mon Sep 17 00:00:00 2001 From: Tejas Deshpande Date: Fri, 7 Feb 2025 14:58:37 -0500 Subject: [PATCH 01/24] Remove the logging of GaugeMetadata to allow using AQS (#6678) Based on the behaviour of AQS w/ Fireperf, an AQS session isn't available when (currently) logging gauge metadata. Changes: - Remove the current logging of gauge metadata - will be re-introduced in a future PR. - Switch Gauge collection from `scheduleAtFixedRate` to `scheduleWithFixedDelay`. As [documented](https://stackoverflow.com/a/78405653), this *should* prevent a potentially large amounts of gauge collection if a process is cached, and then restored during a verbose session - which *should* make it work better w/ AQS. - Remove API restricted behaviour which is no longer relevant. --- .../firebase/perf/FirebasePerformance.java | 1 - .../firebase/perf/session/SessionManager.java | 17 ----- .../session/gauges/CpuGaugeCollector.java | 13 +--- .../perf/session/gauges/GaugeManager.java | 9 +-- .../session/gauges/GaugeMetadataManager.java | 34 +--------- .../session/gauges/MemoryGaugeCollector.java | 6 +- .../perf/session/SessionManagerTest.java | 58 +--------------- .../gauges/GaugeMetadataManagerTest.java | 66 +------------------ 8 files changed, 14 insertions(+), 190 deletions(-) diff --git a/firebase-perf/src/main/java/com/google/firebase/perf/FirebasePerformance.java b/firebase-perf/src/main/java/com/google/firebase/perf/FirebasePerformance.java index 40468566225..3cc49896ce0 100644 --- a/firebase-perf/src/main/java/com/google/firebase/perf/FirebasePerformance.java +++ b/firebase-perf/src/main/java/com/google/firebase/perf/FirebasePerformance.java @@ -182,7 +182,6 @@ public static FirebasePerformance getInstance() { .initialize(firebaseApp, firebaseInstallationsApi, transportFactoryProvider);
