Blob Monitor - Proof of Concept +//! +//! Monitors CTE blob access patterns and auto-adjusts scores based on frecency. +//! +//! Architecture (Two-Map Design): +//! +//! 1. **Telemetry Stats Map** - tracks access patterns by offset +//! - Key: (tag_id, offset) from CTE telemetry +//! - Value: TelemetryStats { access_count, bytes_read, bytes_written, timestamps } +//! - Populated from telemetry polling +//! - Purpose: Understand I/O patterns at offset granularity +//! +//! 2. **Blob Registry Map** - tracks blobs by name for score updates +//! - Key: (tag_id, blob_name) from tag.get_contained_blobs() +//! - Value: BlobInfo { score, last_checked, access_count } +//! - Populated from tag blob discovery +//! - Purpose: THIS is what we use for calling reorganize_blob() +//! +//! 3. **Main Logic:** +//! - Telemetry task updates TelemetryStats by offset +//! - Registry task updates BlobRegistry by name +//! - Main loop: for each blob in registry, calculate frecency → score +//! - Call tag.reorganize_blob(blob_name, new_score) for actual CTE updates +//! +//! # Per-Tag Frecency Limitation +//! +//! **IMPORTANT**: This implementation tracks frecency at the TAG level, not the +//! individual blob level. All blobs within a tag share the same access patterns +//! from telemetry, which is aggregated by tag_id. This is a fundamental limitation +//! of the current telemetry API, which provides offset-based data but no blob-to-offset +//! mapping. +//! +//! For per-blob frecency tracking, CTE would need to expose: +//! 1. Blob-to-offset mappings for each tag +//! 2. Telemetry entries that include blob identification +//! +//! Current behavior: All blobs in a tag inherit the tag's aggregate frecency score. +//! +//! # Lock Ordering +//! +//! To prevent deadlocks, locks must ALWAYS be acquired in this order: +//! 1. `telemetry_stats` (read or write) +//! 2. `blob_registry` (read or write) +//! 3. `known_tags` (read or write) - MUST NEVER be held with other locks +//! +//!

This ensures the C++ code never runs on the +/// async executor's threads, preventing any potential interference with async +/// scheduling. +/// +/// 2. **Per-Instance Isolation**: Each Tag instance is independent. Concurrent +/// operations should create multiple Tag instances (via `duplicate()`), each +/// running in its own `spawn_blocking` context. This matches the C++ design +/// where each Tag object is independent and thread-safe for its own instance. +/// +/// 3. **C++ Thread-Safety Guarantees**: The underlying C++ `wrp_cte::core::Tag` +/// class is designed for single-threaded use within each operation. All state +/// modifications are completed before returning from FFI calls, and the object +/// does not maintain internal threads or async state that could cause races. +/// +/// 4. **No Interior Mutability**: The C++ Tag class does not use interior mutability +/// patterns that could cause data races. All mutations go through explicit FFI +/// calls. +/// +/// # SAFETY +/// +/// This implementation is safe because: +/// +/// - Each Tag instance is used exclusively within `spawn_blocking` closures, +/// ensuring the C++ object is only accessed from one thread at a time. +/// +/// - `spawn_blocking` guarantees that the closure runs on a dedicated thread pool +/// separate from the async executor, preventing async runtime interference. +/// +/// - For concurrent operations, users create separate Tag instances via `duplicate()`, +/// each wrapped in its own `spawn_blocking` context. This eliminates shared state +/// at the Rust level entirely. +/// +/// - The underlying C++ `Tag` object does not use callbacks, signals, or any +/// other mechanism that could cause re-entrancy or cross-thread access. +/// +/// - The C++ object lifetime is managed by `UniquePtr`, which ensures proper +/// destruction when the Rust wrapper is dropped. +/// +/// - No mutable static state exists in the C++ Tag implementation that could +/// cause cross-thread interference. +struct SendableTag(cxx::UniquePtr); + +// SAFETY: SendableTag is safe to send across threads because: +// +// 1. SPAWN_BLOCKING GUARANTEE: The UniquePtr is created within a +// spawn_blocking closure and used exclusively within that closure. +// No concurrent access to the Tag object can occur. +// +// 2. SINGLE-THREADED ACCESS: Each Tag instance is accessed only from the +// thread running the spawn_blocking closure. The UniquePtr is never +// shared across threads for the same Tag instance. +// +// 3. C++ THREAD-SAFETY: The underlying wrp_cte::core::Tag class is +// designed for single-threaded use. It doesn't spawn threads, use atomics, +// or have any internal concurrency. All state changes are completed +// before the FFI call returns. +// +// 4. OWNERSHIP MODEL: UniquePtr ensures proper cleanup. The C++ destructor +// runs exactly once when the UniquePtr is dropped, in the same thread +// that created it (within the spawn_blocking closure). +// +// 5. NO SHARED STATE BETWEEN INSTANCES: For concurrent operations, users +// create separate Tag instances via duplicate(). Each instance has its +// own UniquePtr, eliminating any possibility of shared mutable state. +// +// IMPORTANT: This Send impl is safe because each Tag instance's UniquePtr +// lives entirely within spawn_blocking closures, ensuring single-threaded +// access patterns required by the C++ implementation. +unsafe impl Send for SendableTag {} + +// SAFETY: SendableTag is safe to synchronize across threads because: +// 1. Arc requires SendableTag: Sync for Arc: Send +// 2. Each spawn_blocking closure owns its Arc clone (stack-allocated) +// 3. Concurrent closures access the same SendableTag via Arc, but each +// closure's &SendableTag is scoped to that closure's stack +// 4. IMPORTANT: Users must use Tag::duplicate() for concurrent operations +// to avoid concurrent access to the same C++ Tag object +unsafe impl Sync for SendableTag {} + +/// Wrapper to make unique_ptr Send for use with spawn_blocking +/// +/// This wrapper is necessary because `cxx::UniquePtr` does not implement `Send` +/// by default, which prevents it from being used across thread boundaries. +/// +/// # Thread Safety +/// +/// The wrapper ensures thread-safe access through the following mechanisms: +/// +/// 1. **spawn_blocking Isolation**: The FFI call executes in a dedicated blocking +/// thread pool managed by tokio. Each FFI call runs in isolation. +/// +/// 2. **Per-Call Client Creation**: Unlike Tag, Client objects are created fresh +/// for each FFI call within the spawn_blocking closure. This eliminates any +/// need for mutex synchronization since each call gets its own Client instance. +/// +/// 3. **C++ Thread-Safety Guarantees**: The underlying C++ `wrp_cte::core::Client` +/// class is stateless - it only communicates with the runtime. All state is +/// maintained in the runtime process, not in the Client object itself. +/// +/// # SAFETY +/// +/// This implementation is safe because: +/// +/// - Each FFI call creates a temporary `ffi::client_new()` instance that lives +/// only within the spawn_blocking closure. No state is shared across calls. +/// +/// - The C++ Client provides a stateless interface to the runtime. The only +/// shared state is in the runtime process, which uses its own synchronization. +/// +/// - No mutable static state exists in the C++ Client implementation that could +/// cause cross-thread interference. +/// +/// - The UniquePtr is created, used, and destroyed entirely within the +/// spawn_blocking closure, ensuring proper cleanup in the correct thread. +struct SendableClient(cxx::UniquePtr); + +// SAFETY: SendableClient is safe to send across threads because: +// +// 1. PER-CALL INSTANCES: Each FFI call creates a fresh Client instance inside +// spawn_blocking. No Client is shared across threads or calls. +// +// 2. SPAWN_BLOCKING ISOLATION: The closure runs on a dedicated blocking thread +// pool, ensuring complete isolation from the async runtime and other blocking +// tasks for the duration of the call. +// +// 3. C++ STATELESS DESIGN: The underlying wrp_cte::core::Client class is +// stateless. It only communicates with the CTE runtime via IPC. All shared +// state is in the runtime, which has its own synchronization primitives. +// +// 4. IMMEDIATE CLEANUP: The UniquePtr is dropped at the end of the +// spawn_blocking closure, ensuring proper C++ resource cleanup in the same +// thread that created it. +// +// 5. NO CROSS-CALL STATE: Since each call gets a new Client, there's no +// possibility of cross-thread state sharing or race conditions. +// +// The Send impl is needed to move the closure into spawn_blocking, but the +// actual access pattern (create, use, destroy) within the closure is safe. +unsafe impl Send for SendableClient {} + +// SAFETY: SendableClient is safe to synchronize across threads because: +// 1.

CXX bridge to C++ CTE library +//! +//! This module defines the FFI boundary between Rust and C++ using the cxx crate. +//! Design: All shared types are opaque except primitive scalars. Complex data +//! is passed through output parameters (Vec, Vec). +//! +//! # Architecture +//! +//! The FFI uses the following design patterns: +//! +//! 1. **Opaque Types**: C++ types (`Client`, `Tag`) are exposed as opaque types +//! that can only be created/destroyed through FFI functions. +//! +//! 2. **Output Parameters**: Complex data structures (strings, byte arrays) are +//! passed through output parameters rather than return values, avoiding +//! complex memory management at the FFI boundary. +//! +//! 3. **Primitive Parameters**: All scalar types use C-compatible primitives +//! (u32, u64, i32, f32, f64) that have identical representations in both +//! languages. +//! +//! # Safety Guarantee +//! +//! The cxx bridge provides the following safety guarantees: +//! +//! 1. **Memory Layout**: cxx ensures identical memory layout for all types +//! passed across the FFI boundary, including alignment and padding. +//! +//! 2. **Lifetime Management**: `UniquePtr` provides automatic RAII cleanup +//! of C++ objects when the Rust wrapper is dropped. +//! +//! 3. **Exception Safety**: C++ exceptions are caught by cxx and converted +//! to Rust panics or Result types, preventing undefined behavior. +//! +//! 4. **Thread Safety**: All FFI functions can be safely called from any +//! thread; the C++ implementation handles internal synchronization. + +// Import error types from parent module +use crate::{CteError, CteResult}; + +/// Telemetry entry size in bytes: op(4) + off(8) + size(8) + tag_major(4) + tag_minor(4) + +/// blob_hash(8) + mod_time_nanos(8) + read_time_nanos(8) + logical_time(8) = 60 bytes +pub const TELEMETRY_ENTRY_SIZE: usize = 60;

The internal representation is completely hidden +/// from Rust, preventing incorrect memory access or modification. +/// +/// 2. **Primitive Types**: All scalar parameters use C-compatible types (u32, u64, +/// i32, f32, f64, &str) that have identical bit-level representations in both +/// languages. cxx generates compile-time static assertions to verify compatibility. +/// +/// 3. **Buffer Types**: `Vec` and `Vec` map to C++ `std::vector` +/// and `std::vector` with identical memory layouts and alignment. +/// cxx manages the buffer capacity/size/ptr triplet correctly. +/// +/// ## Ownership Model +/// +/// 1. **UniquePtr**: Factory functions (`client_new`, `tag_new`, `tag_from_id`) +/// return `UniquePtr` which uniquely owns the C++ object. When dropped, the +/// C++ destructor is called automatically. +/// +/// 2. **Borrowing**: All operations accept `&T` references that borrow the UniquePtr. +/// The reference cannot outlive the owner, preventing use-after-free. +/// +/// 3. **String Slices**: `&str` parameters borrow Rust strings with guaranteed null +/// termination provided by cxx's CxxString adapter, preventing buffer overflows. +/// +/// ## Thread Safety +/// +/// 1. **Cross-Thread Movement**: `UniquePtr` is not `Send` by default because +/// C++ destructors must run on the thread that owns the object. The async module +/// wraps these in `SendableTag`/`SendableClient` with explicit SAFETY documentation. +/// +/// 2. **Internal Synchronization**: The C++ implementations use internal mutexes +/// for shared state, ensuring thread-safe concurrent access to the runtime. +/// +/// 3. **No Global State**: The FFI functions don't access mutable global state +/// directly; all state is in Client/Tag objects or the runtime process. +/// +/// ## Exception Safety +/// +/// 1. **C++ Exceptions**: cxx catches C++ exceptions at the FFI boundary and +/// converts them to Rust panics. For FFI functions returning Result, exceptions +/// become Err variants; for infallible functions, they become panics. +/// +/// 2. **Panic Safety**: If Rust code panics across an FFI call, cxx ensures the +/// C++ stack is properly unwound before terminating. +/// +/// ## Undefined Behavior Prevention +/// +/// 1. **Null Pointers**: cxx ensures UniquePtr values are never null when passed +/// to C++ (empty UniquePtr maps to nullptr which C++ handles correctly). +/// +/// 2. **Lifetime Bounds**: All references have lifetime bounds enforced by the +/// compiler; `&str` parameters cannot outlive the calling function. +/// +/// 3. **No Data Races**: The FFI functions don't provide mutable access to shared +/// state without synchronization primitives. +/// +/// # FFI Function Overview +/// +/// ## Factory Functions +/// - `cte_init`: Initialize the CTE runtime +/// - `client_new`: Create a new CTE client +/// - `tag_new`: Create or open a tag by name +/// - `tag_from_id`: Open an existing tag by ID +/// +/// ## Query Functions +/// - `tag_get_id_major`/`tag_get_id_minor`: Get tag ID components +/// - `tag_get_blob_score`: Get blob placement score +/// - `tag_get_blob_size`: Get blob size in bytes +/// - `tag_get_contained_blobs`: List all blobs in a tag +/// - `client_poll_telemetry_raw`: Poll telemetry entries +/// +/// ## Mutation Functions +/// - `tag_put_blob`: Write data to a blob +/// - `tag_get_blob`: Read data from a blob +/// - `tag_reorganize_blob`: Change blob placement score +/// - `client_del_blob`: Delete a blob +/// - `client_reorganize_blob`: Change blob score via client API +#[cxx::bridge(namespace = "cte_ffi")] +pub mod ffi { + unsafe extern "C++" { + include!("shim/shim.h"); + + // Opaque types - managed by cxx + // + // SAFETY: These types are opaque from Rust's perspective.
