Extract the chat store into its own repository - #1346
Merged
Conversation
The chat store materializes the event stream into chats, previews, unread counts, ordering and a search index. Those are application decisions, not protocol ones, and this repository implements the protocol. Nothing about the crate needed to live here: it consumed only the public surface — `Event`, `Jid`, `proto_helpers`, `time`, and one `SqliteStore` — and owned its schema and migrations outright. It was never published, so no released API changes. The bundled-SQLite trim keeps FTS5 despite nothing here indexing on it now. This config is not inherited by consumers, so leaving it on is what keeps proving the subsystem compiles for embedders that want it.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This change removes the in-repository chat-store implementation and tests; without the replacement repository already created and linked, the extracted crate lacks a stable destination and the PR is not merge-ready.

| Filename | Overview |
|---|---|
| Cargo.toml | Removes chat-store from the workspace member list without leaving workspace references behind. |
| Cargo.lock | Removes only the obsolete whatsapp-rust-chat-store package entry and its dependency edges. |
| .github/workflows/main.yml | Removes the deleted package from the hardcoded MSRV check while retaining checks for all remaining published crates. |
| .cargo/config.toml | Updates the bundled SQLite feature rationale while preserving the existing build flags. |
| storages/chat-store/Cargo.toml | Deletes the unpublished crate manifest as part of extracting the entire subsystem. |
| storages/chat-store/src/store.rs | Deletes the chat-store materializer and writer implementation with the rest of the extracted crate. |
| storages/chat-store/tests/chat_store_test.rs | Deletes the chat-store integration suite; the PR explicitly documents that these tests will move to the consumer repository. |

Why
The chat store materializes the event stream into chats, previews, unread counts, thread ordering and a full-text index. Those are application decisions, not protocol ones, and this repository implements the protocol.
Why it is clean to remove
Nothing about the crate required living here. It consumed only the public surface any third-party embedder has:
wacore::types::events(Event,ServerAck,Receipt,LazyHistorySync),wacore_binary::Jid,wacore::proto_helpers,wacore::timewhatsapp-rust-sqlite-storage(SqliteStore), for the connectionwhatsapp-rustcrate at allIt owned its own schema and migrations rather than sharing the device store's, and it was never published to crates.io (
publish = false), so no released API changes.What this costs
Its ~6.3k lines of tests were the strongest integration exercise of the event bus in this repo, and they ran in the same PR that broke an event. After this they run against a pinned revision, so an event change lands green here and surfaces at the consumer's next bump. Worth stating plainly rather than discovering later.
References removed
Workspace member, the MSRV check's package list in
main.yml, the lockfile entry, and the bundled-SQLite comment in.cargo/config.toml. FTS5 stays enabled there: nothing here indexes on it now, but that file is not inherited by consumers, so keeping it on is what proves the subsystem still compiles for embedders who want it.Verification
cargo fmt --checkclean,cargo check --workspaceclean, 4993 tests pass (e2e excluded — they need the mock server). Nochat-store/ChatStorereferences remain anywhere in the tree.
