Integration branch contains packages split, renaming and deletion of deprecated methods

Summary by CodeRabbit

• New Features

  • Added separate device and server SDK entry points with fluent client builders for REST and realtime connections.
  • Added side-specific client identification in requests and agent headers.
  • Added support for publishing device and server artifacts under the new Pub/Sub package namespace.

• Deprecations

  • Deprecated direct AblyRest and AblyRealtime constructors; use the device or server builders instead.

• Documentation

  • Updated README and contribution guidance for the 2.0 package split and migration context.

Walkthrough

The project introduces core, core-android, device, and server modules for version 2.0. It adds device and server client builders, side-specific agent metadata, release artifact validation, updated workflows, and migration documentation.

Changes

Pub/Sub package split

Layer / File(s)	Summary
Module topology and publication setup settings.gradle.kts, gradle.properties, gradle/libs.versions.toml, core/*, core-android/*, device/*, server/*, java/gradle.properties, android/gradle.properties, liveobjects/*, pubsub-adapter/*, uts/*, examples/*	The project replaces the java and android modules with core, core-android, device, and server. Publication metadata and module dependencies use the new structure.
Device and server client entry points device/src/commonMain/kotlin/io/ably/pubsub/device/PubSubDevice.kt, server/src/main/java/io/ably/pubsub/server/PubSubServer.java, shared/src/main/java/io/ably/pubsub/internal/Side.java, lib/src/main/java/io/ably/lib/util/Side.java, lib/src/main/java/io/ably/lib/types/ClientOptions.java, lib/src/main/java/io/ably/lib/transport/Defaults.java, device/src/*Test*, server/src/test/*, lib/src/test/*	The new builders configure AblyRealtime and AblyRest clients. Side-specific agent entries are injected. Client option copying includes headers, fallback hosts, transport parameters, and agents.
Release verification and build workflows build.gradle.kts, .github/workflows/check.yml, .github/workflows/release.yaml, .github/workflows/emulate.yml, .github/workflows/integration-test.yml, .github/workflows/javadoc.yml, deploy/check-archives.sh	verifyReleaseArtifacts checks artifact coordinates and lockstep versions. Release and dry-run workflows execute the check. Test, Javadoc, and archive paths use the renamed modules.
Migration guidance and deprecation references README.md, CONTRIBUTING.md, core/src/main/java/io/ably/lib/rest/AblyRest.java, core-android/src/main/java/io/ably/lib/rest/AblyRest.java, lib/src/main/java/io/ably/lib/realtime/AblyRealtime.java, core-android/src/main/java/io/ably/lib/push/ActivationContext.java	Documentation references the new modules and builders. Existing REST and realtime constructors are deprecated with replacement links.

[sacOO7]

The core split mechanics are implemented well — the exact door surfaces, the io.ably.pubsub:{core,core-android,device,server} coordinates with the core POMs marked internal-use, versionless side flags applied last so they win collisions, the renamed family identifier with a wire-level canary, and single-version lockstep enforced by a release pre-flight. But the branch is not GA-ready: 3 Critical and 9 Major issues follow as individual comments below (plus several Minor/Info ones).

[sacOO7]

(Duplicate submission of the review above, caused by a tooling retry — its inline comments have been removed; please refer to the review above.)

[sacOO7]

[MAJOR] features.yml still passes repository-name: ably-java

features.yml passes repository-name: ably-java into the shared ably/features workflow, which uses it for the OIDC role assumption and the sdk.ably.com upload path. With the repo renamed to ably-pubsub-java (PubSub device/server split rollout, PDR-091b2), the features report will publish under the wrong key or fail role assumption — silently, on push to main. Please update it to ably-pubsub-java in lockstep with the rename (and confirm the ably/features repo knows the new name).

(Posted as a general comment because features.yml is not touched by this PR.)

[sacOO7]

[MAJOR] No 1.x maintenance branch; merge to main strands 1.x fixes

Merging this branch renames the Maven group to io.ably.pubsub, bumps to 2.0.0, and deletes the io.ably:ably-java/io.ably:ably-android artifact definitions — after which main can no longer cut a 1.x security or critical fix. The PubSub device/server split rollout (PDR-091b2) requires a dedicated maintenance branch for the existing packages (security/critical fixes only, 1-year support window, then EOL). No such branch exists on the remote today — only ephemeral release/* branches and the v1.8.2 tag. Please cut the 1.x maintenance branch (e.g. from v1.8.2) before this merges, and state the support-window/EOL plan in the PR description.

(Posted as a general comment because this is about repository/branch state, not a specific changed line.)

[sacOO7]

[MINOR] LIBRARY_NAME build-config fields are dead after the family-identifier flip

LIBRARY_NAME is still generated into BuildConfig for both core ("java") and core-android ("android"), but nothing reads it — Defaults.ABLY_AGENT_VERSION now hardcodes ably-pubsub-java. That also means the Android artifact no longer reports a distinct ably-android-style family; fine under the PubSub device/server split rollout (PDR-091b2), which defines a single family per SDK, but worth a deliberate note. Please drop the dead fields (or add a comment recording that Android intentionally shares the ably-pubsub-java family) so the next reader isn't misled into thinking they still drive the agent string.

(Posted as a general comment because core/build.gradle.kts and core-android/build.gradle.kts are pure renames with no changed lines to anchor to in this PR.)

[sacOO7]

[INFO] No API/binary-compatibility gate on the new public surface

There's no API/binary-compatibility check on the new public door surface — no japicmp, metalava, revapi or Kotlin apiValidation anywhere in the build (also true pre-split, so not a regression); device has Kotlin explicitApi(), which governs visibility only. Reasonable to defer for a greenfield v2 — flagging it so it's a conscious choice rather than an oversight, given these are brand-new public APIs.

Suppressed comments (3)

device/src/androidTest/java/io/ably/pubsub/device/PubSubDeviceTest.java:43

• PubSubDevice only declares the no-argument clientBuilder() method, so this ClientOptions overload does not compile. Configure the returned builder through its fluent methods instead.
  device/src/androidTest/java/io/ably/pubsub/device/PubSubDeviceTest.java:49
• There is no clientBuilder(String) overload in PubSubDevice, so the instrumentation test cannot compile. Use the builder's key method and disable auto-connect for this fake key.
  device/src/androidTest/java/io/ably/pubsub/device/PubSubDeviceTest.java:63
• The new builder has no clientBuilder(ClientOptions) overload, so this call does not compile. Pass the relevant option values through the fluent API; this still allows the test to verify that the caller's agents map is untouched.

recommendation. Preserve the existing internal-artifact warning and dependency

- Line 422: Update the PubSubDevice build method and both PubSubServer build
