Issue #21038 has been updated by k0kubun (Takashi Kokubun). Backport changed from 3.1: REQUIRED, 3.2: DONE, 3.3: DONE, 3.4: REQUIRED to 3.1: REQUIRED, 3.2: DONE, 3.3: DONE, 3.4: DONE ruby_3_4 commit:2108ab2cb68e9d975e4dcf035a11243e1173336f merged revision(s) commit:04ec07794657cd2444ecb001a522b9df2db1b90a. ---------------------------------------- Bug #21038: Preserve `errno` in `rb_fiber_scheduler_unblock` https://bugs.ruby-lang.org/issues/21038#change-111930 * Author: ioquatix (Samuel Williams) * Status: Closed * Backport: 3.1: REQUIRED, 3.2: DONE, 3.3: DONE, 3.4: DONE ---------------------------------------- `rb_fiber_scheduler_unblock` can invoke user code that can affect `errno`, and at least in `io_binwrite`, this is unexpected. Whether `io_binwrite` should be fixed is a separate issue (it probably should be, as `errno` is not explicitly preserved or documented how it is preserved).
