From ea011372c9af60190c01187854f6535f1bc7d21b Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Fri, 22 May 2026 05:37:38 +0300 Subject: [PATCH 1/2] Add com.codename1.crash on-device crash protection client New package for capturing unhandled exceptions on device, scrubbing PII, and uploading structured crash reports to the BuildCloud crash service. Pairs with the new /api/v2/crash/reports server endpoint (separate BuildCloud PR). Surface: - CrashProtection.install() / setEnabled() / setScrubber() / capture(). Endpoint is fixed; opt-in is developer-controlled and persisted in Preferences (default off). - PiiScrubber is a public subclassable class. Default rules: emails partially redacted (keep first 3 chars + full domain), runs of 6+ digits collapsed to [num]. URLs are NOT scrubbed. - Storage-first delivery: every payload is written to Storage with a fresh eventId BEFORE the POST; the storage entry is deleted only on a 2xx. Failed sends are retried on next launch. The server uses eventId for idempotent dedup. Wire-up: - Android: AndroidImplementation's UncaughtExceptionHandler now also forwards to CrashProtection.capture(e), guarded by try/catch so a bug here can't suppress the legacy Log.bindCrashProtection path. - iOS: no client change. The existing signal handlers in CodenameOne_GLAppDelegate.m convert signals to JVM exceptions which flow through the EDT error handler naturally. Build-server utility: - maven/codenameone-maven-plugin/.../util/CrashSymbolUploader. Used by the cloud build executor's post-build hook to POST mapping.txt (Android) or the dSYM zip (iOS, release builds only) to the /api/v2/build/{buildKey}/symbols endpoint. Standalone, no Spring dep. AndroidGradleBuilder + IPhoneBuilder carry comments pointing the executor at the right call sites. Java 5 source compatibility maintained in the core client classes. No new runtime dependencies on the device. ASCII-only sources; CodenameOne header (not Oracle).

Opt-in detection (build-time) - New CrashProtectionOptIn utility decides per-build per-platform whether to upload symbols. Two independent signals trigger upload; either is sufficient: 1. codename1.crashProtection.enabled=true in the project's codenameone_settings.properties (build hint). 2. The user's compiled classes reference com.codename1.crash.CrashProtection (bytecode scan over the classes directory or jar -- the API name appears in the constant pool of any class that imports it). Per-platform opt-OUT via codename1.crashProtection..enabled=false. Defaults to enabled for every platform when the global signal is true. Per-platform runtime gate - CrashProtection.install() now reads codename1.crashProtection..enabled at runtime via Display.getProperty and no-ops on the current platform when set to false. Property is baked into the deliverable from the build-time settings file; runtime check uses Display.getPlatformName() lowercased. Symbol upload wiring - CrashSymbolUploader extended with PLATFORM_MAC / PLATFORM_LINUX / PLATFORM_WIN32 + per-platform helpers and env-var-based endpoint / secret / buildKey resolvers. - LinuxNativeBuilder + WindowsNativeBuilder call the uploader at the end of build() with the produced binary (and, for Windows, the .pdb when present -- preferred over the .exe for symbolication). - Mac native delegates from IPhoneBuilder; the existing hook comment in IPhoneBuilder covers both iOS dSYM + Mac native uploads from the executor's post-build stage. - Android (mapping.txt) + iOS (dSYM) hook comments updated to reference the new opt-in helper. - All builders fail open: an upload failure never fails the build. Docs - New Crash-Protection.asciidoc chapter in the developer guide: setup checklist, opt-in signals, per-platform opt-out, PII scrubber defaults, tier quotas + retention, repo mapping flow. - pricing.md gains 4 new Crash Protection FAQ entries (what is it, how to enable, storage limits, per-platform opt-out, where crashes end up). - faq.md links Crash Protection from the production-functionality section. What's NOT in this PR - Server-side gate flip from > USER_TYPE_ENTERPRISE to >= USER_TYPE_PRO. That lives in BuildCloud and is a single-line change that should land AFTER this PR ships -- otherwise Pro customers see the UI but the build-server symbol upload isn't there yet.

      + *
    1. Build hint property: + * {@code codename1.crashProtection.enabled=true} in + * {@code codenameone_settings.properties} (the app project's + * build configuration). Lets a developer flip crash protection + * on without having to commit to also calling the runtime API + * yet.

Means the user wired the + * runtime API and we infer build-time intent.
      3. + *
    + * + *

    Per-platform opt-OUT: even when the global signal is true the + * developer can disable a specific platform with + * {@code codename1.crashProtection..enabled=false}.
