…icy, the binder deploy channel, stage-cost telemetry Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Kj9YeCDHGp9DU8LPtfWJ7W
…icity, deploy teardown - Swallowed linkToDeath failure -> a binder dead at connect is reported as an instant death and never registered, so deploys fail fast as NotConnected instead of timing out with the freezer hold kept on a dead package (tests: "a binder that is dead at connect is not left registered", "a dead binder's stale connect retry does not clobber a live registration"). - Non-atomic connect watch/registration -> registration and death watch are one @synchronized step, and death delivery shares the lock, so the watched binder and the registered target can never disagree and a death cannot slip between link and registration (test: "a death delivered while connect is registering still clears the target"; wiring: "a reconnect moves the watch, and firing it clears the registration"). - Restart payload retained with hot-swap metadata -> a confirmed restart deploy clears the retained set instead of retaining it, so a reconnect catch-up can never hot-swap over the live restart-sensitive component and falls back to the forced rebuild (test: "a confirmed restart deploy clears the retained payload instead of retaining it"). - endSession leaving an in-flight deploy to time out -> endSession routes through onDisconnected, whose Disconnected report answers the waiter deterministically (test: "ending the session answers a deploy awaiting its verdict as Disconnected"). - Adjacent minor: disconnect() now unlinks the death watch, so no stale recipient outlives a graceful disconnect (test: "a graceful disconnect unlinks the death watch").

📝 Walkthrough
WalkthroughAdds the core live-reload pipeline for Quick Build. The changes define reload decisions, build orchestration, asset packaging, proxy deployment and recovery, generation persistence, session messages, and end-to-end telemetry. Extensive JVM tests cover concurrency, deployment, parsing, retention, and save coalescing. ChangesAsset packaging
Reload domain
Live-reload orchestration
Proxy deployment
Telemetry
Save coalescing
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The changes can let an obsolete proxy disconnect break a replacement connection and can interrupt the editor during save-triggered restarts, affecting reload correctness and the user workflow; merge should wait for these paths to be fixed or explicitly accepted.

- Around line 57-60: Update packageAssets to deduplicate the mapped entries by
their normalized relative path before writing the ZIP and constructing
relativePaths. Use the rel value produced by relativeAssetPath as the uniqueness
key, while retaining one corresponding file for each path so ZipOutputStream
receives no duplicate entry names.

- Around line 248-259: Update the reconnect-generation branching in
PayloadDeployer so every reconnectGeneration value unequal to generation is
treated as a mismatch, including newer generations; retain the existing success
path only for exact equality and preserve the outdated-baseline rebuild outcome
for mismatches.
- Around line 209-234: The restart handling around ProxyAppLauncher.launch must
not foreground the proxy app when userInitiated() is false. Defer relaunch until
an explicit Quick Build action, or use a non-foregrounding restart mechanism,
while preserving the existing reconnect and failure behavior for user-initiated
deploys.
In
`@quickbuild/core/src/main/java/org/appdevforall/cotg/quickbuild/service/deploy/QuickBuildHostService.kt`:
- Around line 147-154: Update disconnect and the registration flow around
HostBinder.enforceCaller and ProxyAppConnections so each successful connect
records a per-registration caller identity or token, then disconnect validates
that identity before invoking clearDeathWatch and connections.onDisconnected.
Ignore stale disconnects from superseded proxies, while preserving disconnect
behavior for the currently registered proxy.
In
`@quickbuild/core/src/main/java/org/appdevforall/cotg/quickbuild/service/telemetry/MetricsReporting.kt`:
- Around line 19-24: Update report to rethrow CancellationException before
logging, and catch only ordinary reporting failures rather than all Throwable
values; ensure JVM Error types and coroutine cancellation propagate while
regular metrics sink exceptions still produce the existing warning.
In
`@quickbuild/core/src/test/java/org/appdevforall/cotg/quickbuild/domain/reload/LiveReloadOrchestratorTest.kt`:
- Line 14: Remove the unused report import from LiveReloadOrchestratorTest,
leaving the remaining imports and test code unchanged.
In
`@quickbuild/core/src/test/java/org/appdevforall/cotg/quickbuild/domain/telemetry/E2eTimelineGroupsTest.kt`:
- Around line 57-65: Update the singles list in `each HostSpans field alone
makes the group non-empty and counts toward the total` to include
`E2eTimeline.HostSpans(queueMillis = 7)`, covering the queue-only `isEmpty` and
total behavior alongside the existing fields.

Java ZipOutputStream putNextEntry duplicate entry ZipException official documentation
💡 Result:
In Java, the ZipOutputStream.putNextEntry(ZipEntry e) method throws a ZipException if a ZIP format error occurs [1][2]. While the official documentation does not explicitly detail every possible condition for a "duplicate entry" error in the text of the method description, it is a well-established behavior of the implementation that attempting to add an entry with a name that already exists in the ZIP archive will trigger this exception [1][3]. This behavior occurs because the ZIP file format maintains a central directory, and duplicate entry names are generally considered invalid or ambiguous within a single ZIP file structure. When you call putNextEntry with an entry name that has already been processed and closed in the current stream, the underlying implementation detects this conflict and throws a ZipException to indicate the violation of the ZIP format requirements [1][4]. To avoid this, ensure that your application logic tracks the names of entries already added to the ZipOutputStream (e.g., using a Set) and checks for duplicates before calling putNextEntry [1][2].

Deduplicate asset-relative paths before writing the ZIP.
packageAssets accepts a Collection<File>, and relativeAssetPath normalizes each path. Two lexical aliases can produce the same ZIP entry name. ZipOutputStream.putNextEntry rejects the duplicate and can abort asset packaging. Deduplicate by rel before writing the ZIP and constructing relativePaths.

E2eTimeline provides format(), but it does not provide parse. The current text documents an API that callers cannot use.

Do not foreground the proxy app for a save-triggered restart.
When userInitiated() is false, this path still calls ProxyAppLauncher.launch(). The launcher resumes the proxy app task and interrupts the editor. PayloadDeployerTest lines 91-108 confirms this behavior.
Defer the relaunch until an explicit Quick Build action, or implement a restart path that does not foreground the app.

Require the exact deployed generation after restart.
A reconnectGeneration greater than generation reaches the success branch. This returns BuildOutcome.Success(generation) although the proxy app reported a different generation.
Treat every reconnectGeneration != generation result as a mismatch, unless the protocol explicitly supports advancing to a newer generation here.

Android Binder.getCallingPid AIDL transaction caller process identity official documentation
💡 Result:
To identify the caller of an AIDL transaction in Android, you can use the static Binder.getCallingPid and Binder.getCallingUid methods [1][2]. These methods return the process ID (PID) and Linux user ID (UID) of the process that initiated the transaction currently being processed [1]. Key Technical Details: - Context: These methods must be called within the implementation of an AIDL interface method to retrieve the identity of the remote caller [1][3]. If the current thread is not executing an incoming transaction, these methods return the PID or UID of the current process [1][4]. - Limitations of PID: The Android documentation explicitly warns not to use the PID as a security identifier because PIDs can be reused [1]. - Oneway Transactions: For one-way (asynchronous) AIDL transactions, the calling PID is reported as 0 [1][2]. - Alternative Backend APIs: Depending on the implementation language of your service, different APIs provide the same caller identity information [2]: - Java: Binder.getCallingPid and Binder.getCallingUid [2] - C++: IPCThreadState::self->getCallingPid and IPCThreadState::self->getCallingUid [2] - NDK: AIBinder_getCallingPid and AIBinder_getCallingUid [2] - Rust: ThreadState::get_calling_pid and ThreadState::get_calling_uid [2] For security and permission checks, using Binder.getCallingUid is generally preferred over PID, as the UID is stable and tied to the application's identity [1][5]. You can resolve the UID to a package name using PackageManager.getNameForUid(int uid) or getPackagesForUid(int uid) [6][3][5].

Guard disconnect against superseded registrations. IQuickBuildHost.disconnect(String) has no registration token. HostBinder.enforceCaller checks only the shared UID, while disconnect calls the unconditional ProxyAppConnections.onDisconnected() path. An old proxy can therefore disconnect after a replacement completes connect, clearing the replacement target and releasing the freezer hold. Store a per-registration caller identity or token and ignore stale disconnects.
