signal-hook

• Documentation about SIGBUS (#204).

• Don't exclude .c files from release package.

• Fix double-close on pipe unregister (#200).
• Don't include development scripts in release package (195).

Version 0.4.1 (don't pin dep versions)

• Don't pin specific dependency versions accidentally.

Not bumping the async crates - they use it, but they don't expose the
changed API.

• Changed the low_level::pipe to look OwnedFd instead of IntoRawFd, to enforce ownership of the file descriptor (#196).

• Fix race condition leading into a panic in SignalsInfo::forever (#148).

• Fix compilation on OpenBSD (#147).

• Added the SIGINFO signal (where available).

• Add haiku support.

• Fix accidentally broken windows build.

• Provide fallback sigaddset, sigemptyset on certain androids, as they are missing them.

• Doc link fixes.

• Deliver SIGCHLD even on stop/continue.

• Fix docs.rs build.

• Unmask a signal in default emulation if it is termination.

• Fix the labels on docs.rs :-|.

• Doc: include the features & these little labels inside docs.

• Fix feature dependencies (iterator depends on channel).

• low_level::emulate_default_handler to emulate whatever default handler would do.
• low_level::signal_name to look up human readable name.
• The Origin's debug output now contains the human readable name of the signal.

• Allow extracting Origin from the raw siginfo_t structure by hand, without needing an iterator.
• Folding the signal-hook-sys inline (but still compiling C code only conditionally).
• WithRawSiginfo extractor (to get hands on the raw siginfo_t).
• Bugfix: Don't leak on WithOrigin destruction.

• Use caret dependencies where appropriate (to allow upgrades on signal-hook-registry).

• The cleanup module is gone, it was not a good API. Replaced by conditional termination in flag.
• Some abstractions/patterns are moved to low_level submodule, as they are considered building blocks, not for direct use (register, pipe, channel).
• The signal constants are moved to a submodule (consts), together with few more constants, to not clutter the root.
• The forever iterator no longer consumes.

• Extractor for the origin of a signal (PID, UID, what caused it).
• Fixing some doc links on re-exports.

• Allow turning the iterator module off (the iterator feature, part of default features). This would allow compiling the crate on 1.31.0.

• Bump minimal rustc version to 1.36.0 (signal-hook-registry still builds with 1.26.0).
• (Breaking) Support for exfiltrators ‒ ability to return more than just the signal number from the iterator and streams. Nothing more is implemented yet, but the place to put it is reserved in the API.
• (Breaking) pipe::register_raw now takes ownership and tries to use send first, falls back to O_NONBLOCK and write on failure.
• (Breaking) All async support is pulled out into separate crates, to decouple from the async runtime release cycles on the main signal-hook crate.
• Inner parts of the Iterator are now exposed in signal_hook::iterator::backend, to support the async crates.

• Fix possible blocking in signal handler registered by Signals.

• Make Signals work in edge-triggered mode in mio too, by always draining everything from the socket. Needed, because mio 0.7 doesn't have level-triggered any more.

• mio-0_7-support feature for use with mio 0.7.0+.
• Bump minimal rustc version to 1.31.0 (signal-hook-registry can still build with 1.26.0).

• Some doc clarifications.

• cleanup module to register resetting signals to default.

• Docs improvements.
• Fix registering pipes as well as sockets into the pipe module (#27).

• Fix busy loop in Iterator::forever when the mio-support feature is enabled (#16).

• The Signals iterator can now be closed (from another instance or thread), which can be used to shut down the thread handling signals from the main thread.

• The Signals iterator allows adding signals after creation.
• Fixed a bug where Signals registrations could be unregirestered too soon if the Signals was cloned previously.

• The internally used ArcSwap thing doesn't block other ArcSwaps now (has independent generation lock).

• Re-exported signal constants, so users no longer need libc.

• Compilation fix for android-aarch64

• Tokio support.
• Mio support.
• Dependency updates.

• Dependency updates.

• Get rid of catch_unwind inside the signal handler.
• Link to the nix crate.

• Initial basic implementation.
• Flag helpers.
• Pipe helpers.
• High-level iterator helper.
