26.07

• breaking: Merge Noelware.Violet.Subprocess into the main repository. Everything is now available under //violet/subprocess
  rather than a separate framework package. (@auguwu)
• breaking: VIOLET_DEPRECATED / VIOLET_DEPRECATED_BECAUSE now take the version as a string literal (e.g. "26.07") instead of a bare token; the previous form silently produced malformed deprecation messages (@auguwu)
• Some classes, methods, typedefs, functions, etc. is marked with what versions they were introduced. Also, stablization points for experimental frameworks. (@auguwu)
• Remove violet::experimental::SmolString, now use violet::SmolString (@auguwu)

Noelware.Violet

• breaking: Removed ThreadSafety template paramter in CancellableDefer and added LocalCancellableDefer instead (@auguwu)
• breaking: Removed more deprecated macros (@auguwu)
• Added RefCnt and RefCntTraits, a way to externally provide reference counting (@auguwu)
• Added violet::Drop<T>, a no-op sink to deliberately consume and destroy a value (@auguwu)
• Added VIOLET_DISALLOW_COPY_SINCE macro, for deleting copy operations with a NOELDOC_SINCE annotation (@auguwu)
• [events] Disallow copy and move on events::Emitter<Event> (@auguwu)
• [events] Allow persisted guards to cleanup itself rather than doing it manually (@auguwu)
• [support/demangle] Added initial support for MSVC C++'s ABI but is unavailable. This will properly be available once Windows support is available (@auguwu)
• [support/demangle] Added getting the demangled C++ exception type if we are in a catch (...) block (@auguwu)
• [container/optional] Allow T in Optional to have non-copyable and non-movable types (@auguwu)
• [container/optional] Remove Value() accessor and operator== from Some<T> (@auguwu)
• [container/optional] Disallow copy and move operations if T is not copy or movable (@auguwu)
• [container/result] Remove Value() accessor and operator== from Ok<T> (@auguwu)

Noelware.Violet.IO

• Add source location tracking for OS-level errors (@auguwu)
• Disallow copies on FileDescriptor (@auguwu)
• Add FileDescriptor::Release(), which will release the descriptor to the caller (@auguwu)
• FileDescriptor is now non-copyable (@auguwu)
• FileDescriptor is now from 16 bytes to 4 bytes on Unix platforms, the SharedPtr<Impl> indirection is gone and the descriptor is stored inline (@auguwu)
• Add operator<<(std::ostream&, FileDescriptor). ToString() format changed from FileDescriptor(<id>) to fd(<id>) (@auguwu)
• On Windows, FileDescriptor::value_type is now HANDLE rather than void* (@auguwu)

Noelware.Violet.Filesystem

• breaking: Deprecate the free filesystem::Metadata(PathRef, bool followSymlinks) function in favour of Metadata::For(path, SymlinkResolution) (@auguwu)
• Add Metadata::For overloads for an open FileDescriptor, a (dirfd, path) pair (resolved via fstatat), and PathRef (@auguwu)
• Add SymlinkResolution enum (Follow / NoFollow) to make symlink behaviour explicit at call sites (@auguwu)
• Extend Metadata on Unix with Inode, Device, DeviceMajor, DeviceMinor, Rdev, RdevMajor, RdevMinor, UserID, GroupID, and HardLinks (@auguwu)
• Add Mode::GroupCanRead / GroupCanWrite / GroupCanExecute, which had been missing from the POSIX mode accessors (@auguwu)
• Add BasePath::WithCStr, which invokes a callable with a NUL-terminated view of the path, borrowing the existing storage when possible and falling back to a stack buffer or temporary String otherwise (@auguwu)
• Dirs and WalkDirs now derive from Iterator<...>, are non-copyable but move-constructible, and expose StopTraversing() to end iteration early (@auguwu)
• WalkDirs no longer silently swallows directories it cannot descend into, the failing openat surfaces as an io::Error item on the next Next() call (@auguwu)
• ReadDir, SetWorkingDir, and File::Open route their paths through WithCStr, removing the implicit static_cast<CStr>(path) copies (@auguwu)
• filesystem::Copy on Linux now falls back to a userspace read/write loop when copy_file_range is unusable (cross-filesystem copies on kernels < 5.3 returning EXDEV, sandboxes that block the syscall with ENOSYS, and EINVAL / EOPNOTSUPP / EPERM / EBADF from certain filesystems and pseudo-files), instead of failing outright (@auguwu)
• filesystem::Copy on Linux now mirrors the source file's permission bits onto the destination rather than hardcoding 0644 (@auguwu)
• Fix RemoveAllDirs failing with ENOTEMPTY: directories are now removed after their contents (deepest-first) instead of on first visit during the pre-order walk (@auguwu)

Noelware.Violet.Filesystem.Experimental

• Added Dir, analogus to violet::filesystem::File but for directories (@auguwu)

Noelware.Violet.Subprocess (from 26.06)

• ChildStdin, ChildStdout, and ChildStderr are now non-default-constructible, non-copyable, and move-only, they wrap an owning FileDescriptor and the previous implicit copies were unsound (@auguwu)
• [macOS] Child::Wait now falls back to waitpid when kevent registration fails with ESRCH (the child already exited between Spawn and Wait), instead of surfacing the error (@auguwu)

Noelware.Violet.Experimental

• Added violet::experimental::Slice, which is a std::array-like container (@auguwu)

Noelware.Violet.Experimental.Synchronization

• Added violet::experimental::sync::ReadWriteLock, which is a shared-or-exclusive mutex (@auguwu)
• Added violet::experimental::sync::WaitGroup (@auguwu)

Noelware.Violet

• Move type traits and concepts into their own header: violet/Traits.h (still re-exported when using violet/Violet.h header) (@auguwu)
• Optional: Allow non-assignable copy/move operations to be available. (@auguwu)
  • This disallowed Optional<std::pair<const K, V>> (like Abseil's absl::flat_hash_map) when building iterators.

Noelware.Violet.Experimental

• New types: Mutex (MutexLock, Condvar), Synchronized, and Own. (@auguwu)
  • Violet can use Abseil's Mutex types if provided via --@violet//buildsystem/bazel/flags:abseil=True. We set this to False; Noelware interally uses Abseil but for consumers that don't want to depend on Abseil.
  • Own is a version of std::shared_ptr that works with shared base types that point to derived types and other fixes.
• New integral-based functions arrive from Eous' codebase. (@auguwu)
• Deprecate VIOLET_HAS_EXCEPTIONS, VIOLET_USE_RTTI, VIOLET_IS_LITTLE_ENDIAN, and VIOLET_IS_BIG_ENDIAN for VIOLET_FEATURE_{EXCEPTIONS|RTTI} / VIOLET_PLATFORM_{LITTLE|BIG}_ENDIAN for consistency (@auguwu)
• Add anyhow::Error::ToString (@auguwu)

Noelware.Violet.Experimental.Time

This is a brand new framework that was brought from Eous' codebase.

This comes with Duration, TimePoint, and Instant for time manipulation and parsing that bridges C++'s std::chrono. Also provides Clock and FakeClock, which can be used instead of std::chrono::{system|steady}_clock. FakeClock's primary use is for tests.

Noelware.Violet.Filesystem

• Fix bug where CreateDirectories using the full path instead of current segment (@auguwu, #47)
