gem andrequire 'sorted_set'
to useSortedSet
. [Feature #21287]
C API updates¶ ↑
-
-
rb_thread_fd_close
is deprecated and now a no-op. If you need to expose file descriptors from C extensions to Ruby code, create anIO
instance usingRUBY_IO_MODE_EXTERNAL
and userb_io_close(io)
to close it (this also interrupts and waits for all pending operations on theIO
instance). Directly closing file descriptors does not interrupt pending operations, and may lead to undefined behaviour. In other words, if twoIO
objects share the same file descriptor, closing one does not affect the other. [Feature #18455]
