v1.2.0

Breaking Changes

• Unified Cancellable<T> type — CancellableFuture<T> and CancellableTask<T> are merged into a single Cancellable<T> struct. asyncio::Promise subclasses are replaced with using declarations for zero::async::promise types; EventLoop now implements IExecutor for callback dispatch (include/asyncio/task.h, include/asyncio/promise.h)

• Path ops are now synchronous — absolute(), relative(), proximate(), and currentPath() no longer return Task; they are re-exported as synchronous zero::filesystem functions via using declarations. canonical() and weaklyCanonical() remain async since they resolve symlinks via blocking syscalls. Migration: remove co_await at call sites (include/asyncio/fs.h)

• Unified error handling policy — Establish a consistent rule: extreme errors (OOM, invariant violations, programming errors) throw; normal/recoverable errors return via std::unexpected:

  • Factory functions from(), make(), pipe() now return values directly and throw on failure — callers no longer need to Z_EXPECT their results
  • Compressor::reset(), Decompressor::reset(), and PseudoConsole::resize() now return void
  • SSL/BIO allocation failures now throw, consistent with standard library OOM semantics
  • SSL_CTX_get_cert_store postcondition is now asserted rather than returned as an error

• Coroutine parameters must not be passed by reference — Passing parameters by reference to coroutines is unsafe due to lifetime issues; affected API signatures have been corrected

New Features

• error::capture() — Add a capture function that catches thrown exceptions and converts them to std::expected, providing a uniform way to bridge exception-based and error-code-based paths in coroutines (include/asyncio/error.h)

• readDirectory / walkDirectory overloads — Add overloads accepting a DirectoryOptions parameter to control traversal behavior (e.g. following symlinks) (include/asyncio/fs.h)

• HTTP server sample — Add sample/http/server.cpp with a complete HTTP server usage example

• gRPC integration samples — Add sample/grpc/ with full client and server examples plus a .proto definition demonstrating gRPC integration

Bug Fixes

• Windows process termination race — TerminateProcess returning ERROR_ACCESS_DENIED after the process has already exited is now treated as success (src/process.cpp)

• Unexpected HTTP status codes — HTTP client now correctly handles non-2xx and other unexpected response status codes instead of silently ignoring them

Internal Improvements

• Use C++ Concepts to constrain callable types in templates, yielding cleaner interfaces and better error messages (include/asyncio/concepts.h and various headers)
• Adapt to zero's new executor-based promise/future mechanism
• Remove redundant std::move in co_return statements
• Add -Wa,-mbig-obj compile flag for MinGW to handle large object files

CI

• Upgrade actions/cache from v4 to v5
