lua: CMakeLists: drop redundant cmake_minimum_required

2025-10-07T12:19:52Z

The Lua module depends on the parent libubox project and can't be built independently. Drop redundant cmake_minimum_required from lua/CMakeLists.txt and inherit the version from the parent CMake project to keep version consistency.

lua: build: require CMake >= 3.10 due to dropped legacy support

2025-10-04T10:05:10Z

CMake version 4.0 and later require minimum version of 3.5 or later. Update to minimum version 3.10 which is the last not deprecated minimum version. CMake 3.10 was released in November 2017 and is included in Ubuntu 18.04. Suggested-by: Hannu Nyman Signed-off-by: Hauke Mehrtens

uloop: add support for user defined signal handlers

2023-11-02T16:56:45Z

Reuse and extend the existing signal waker pipe mechanism to add user defined signal handling functionality to uloop. This commit introduces two new api functions `uloop_signal_add()` and `uloop_signal_remove()` along with a new structure type `uloop_signal` to allow adding and removing arbitrary signal handlers. Registered signal handlers are maintained in a linked list and matched by their signo member value which allows registering multiple handlers for the same signal numbers. Upon registering a new signal handler, the existing handler is saved in the `uloop_signal` structure. When removing the user defined signal handler, the original behavior is restored. The Lua binding has been updated as well to support the new signal handler mechanism. Signed-off-by: Jo-Philipp Wich

uloop: add support for interval timers

2023-11-02T16:49:55Z

So far, the only way to implement periodic interval timers was to use one-shot uloop_timeout timers which are rearmed within their completion callback immediately on expiration. While simple, this approach is not very precise and interval lengths will slowly drift over time, due to callback execution overhead, scheduling granularity etc. In order to make uloop provide stable and precise interval timer capabilities, this commit introduces a new `uloop_interval` structure along with the new related `uloop_interval_set()`, `uloop_interval_cancel()` and `uloop_interval_remaining()` api functions. Periodic timers are implemented using the timerfd facility an Linux and kqueue EVFILT_TIMER events on macOS/BSD. The Lua binding has been updated to include support for the new timer type as well.

lua/uloop: fd_add: use absolute indices for arguments

2020-07-11T09:15:12Z

Instead of having to adjust the index repeatedly as the stack is manipulated, use absolute addressing for the function arguments, so they stay the same throughout the call. Zero functional change, just subjectively easier to follow variables. Signed-off-by: Karl Palsson

lua/uloop: make get_sock_fd capable of absolute addresses

2020-07-11T09:15:12Z

The original code required the use of relative addresses into the lua stack. It should accept either. Signed-off-by: Karl Palsson

lua/uloop: fd_add() better args checking

2020-07-11T09:15:12Z

Actually check for flags being valid, instead of simply ignoring the call if flags was zero. Use standard lua checks for the function argument, so you can get a normal "argument #2 was invalid, expected function, got xxx" instead of the vague, "invalid arg list" Signed-off-by: Karl Palsson
