libuev

Changes

• Copyright updates, including LICENSE file, year + author last name
• Add tar.gz archives to distribution
• Enable .sha256 checksums for all tarballs

Fixes

• Debian packaging fixes only

Fixes

• Debian packaging fixes only.

Changes

• Support for Linux eventfd, uev_event_*() see API.md for details

NOTE: You now have to explicitly include sys/queue.h, or provide a local version of queue.h, if your application depends on it.

Changes

• Replaced BSD queue.h doubly-linked lst API with own implementation. Making libuEv stand-alone, no longer imposing any particular version of queue.h on the user
• Enforce -std=gnu11 to unlock typeof() in older GCC versions
• Code cleanup

Fixes

• Fix missing header deps. in Makefile.am, library did not rebuild properly if any of the local header files were changed

Changes

• Update joystick example, use first device, /dev/input/js0
• Minor refactor of uev_exit(), use _SAFE macros to traverse list of watchers instead of while()
• New API test to verify that uev_exit() terminates properly
• Make uev_signal_stop() idempotent

Fixes

• Let uev_timer_stop() call close() on the timerfd directly, do not call uev_timer_set() since that may cause lockups or hangs

Changes

• Minor refactor of event loop after fixing the nasty use-after-free bug in v2.1.1. Code can now be collapsed and noticeably simplified

Fixes

• Issue #17: Check if AM_PROG_AR macro exists before calling it, fixes problem building libuEv on systems with older autoconf + automake. Patch by Markus Svilans
• Fix minor issue with unit tests, return result of test not event loop

Fixes

• Fix use after free in main event loop if watcher deletes itself in the callback. I.e., the callback must be the last action for the watcher in the event loop
• Doc timer example fix by @tisyang
• Doc timer updates, non-zero timeout required

Changes

• Remove event loop error tracking used to trigger a epoll_create1() at a certain error threshold. This tracking was first introduced in [v1.1.0][], triggered by spurious EPOLLERR on I/O watchers
• Unconditionally stop I/O watchers that return EPOLLERR or EPOLLHUP, it is up to the watcher callback to clear the error and/or read() the last few bytes from the descriptor. HUP usally means EOF, or that the remote end of a stream or pipe closed, this may also be signaled by read() returning zero
• Add missing --enable-examples to configure script
• Update documentation, both README.md and API.md

Fixes

• Properly stop and de-register signal and cron/timer watchers from the epoll socket in case of errors, problem introduced in v2.0.0
• Mark watcher file descriptor as unintialized on internal error
• Fix double-close of cron/timer watchers. Problem triggered when the timer expires and calls uev_exit(), which stops all watchers. When the timer callback returns another call to stop the watcher triggered the double close()
• Fix unit test's error handling in watcher callbacks, for reference
• Fix use-before-set in cronrun unit test
• Make sure to restart unit test's I/O watchers on UEV_ERROR
• Make sure to restart example I/O watchers on UEV_ERROR
• Properly check for UEV_HUP in unit tests and examples

Beware, this is a major release, introducing incompatible changes to the failure modes of uev_run() and watcher callbacks. Most users will most likely not notice any difference, but please read on.

Changes

• uev_run() no longer exits the main event loop if an unrecoverable error with a watcher occurs. Instead, the watcher is disabled and the callback is run one last time with events set to UEV_ERROR.
• Watcher callbacks must handle UEV_ERROR conditions. This pertains in particular to signal and timer watchers.
• Examples and API docs updated with the new failure modes.

Changes

• Support for edge triggered and oneshot event types
• Add make package build target to trigger a .deb package build
• Support 64 bit time_t on 32 bit GLIBC systems

Fixes

• bench.c: Use signal.h, not non-standard sys/signal.h

Fixes

• Fix build regression in v1.5.1

Changes

• Add support for checking if a watcher is active.
• Refactor unit testing framework

Changes

• Add support for absolute timers with the uev_cron_*() API.
• Update build & install instructions in README

Fixes

• Fix uev_timer_set() so that it returns error in case the underlying
  Linux timerfd API fails.

Changes

Add range checks for period and timeout to uev_timer_init() and uev_timer_set().
If either on is < 0 libuEv now return ERANGE.

Changes

• Add some pkg-config integration tips for developers using libuEv
  with GNU autotools in their projects.

Fixes

• Add missing SFD_CLOEXEC and TFD_CLOEXEC to signal and timer file
  descriptors. This prevents these file descriptors from "leaking" into
  sub-processes of the parent thread. The kernel will atomically close
  these descriptors for forked-off children calling the exec*() family
  of syscalls.
• Minor coding style fixes and simplification of build scripts.

This release changes the header file namespace, which was silently introduced in v1.2.1.
Apologies for any problems this may cause!

Changes

• Change namespace for header files: libuev/ to uev/, e.g. using
  pkg-config your C program must now #include <uev/uev.h>
• Support for EPOLLPRI events for I/O watchers, thanks to Markus Svilans
• Simplified joystick example
• Updated README slightly

Fixes

• Remove symlinks to Markdown files from GIT
• Distribute and install Markdown files: README.md, etc.

Changes

• Change to GNU configure and build system
• Default optimization is now -O2, not -Os, which can be a bit
  unpredictable with some cross compiler toolchains. -O2 is
  the tried and tested path, and default in autotools
• Added -Wextra to the previous -W -Wall, drop -Werror
  which is supposed to be used by maintainer(s) only.

Fixes

• Do not allow VERSION to be overloaded by build system.
• Make sure we don't inherit LDFLAGS from environment.

Very minor release.

Changes

• README.md updates, mostly cleanup and readability improvements
• make test now runs the test case, on behalf of Travis-CI
• Renamed CHANGELOG.md to ChangeLog.md
• Dropped TODO.md from distribution archives, only for devs

Fixes

• Lots of Markdown syntax fixes in both README and ChangeLog
• Silence annoying warning from newer GNU ar in Ubuntu 15.10
