> I used ucontext API because it can restore the signal mask after a call to `swapcontext`. The setjmp/longjmp mechanism doesn't seem to work with signals. Do you think it's better to close this PR and re-open a different one with the suggested changes ? After reading the related document carefully, I think at least there are at least two other possible, simple and portable method than ucontext: 1.call sigaction with SA_NODEFER http://man7.org/linux/man-pages/man2/sigaction.2.html 2.call sigsetjmp and siglongjmp https://linux.die.net/man/3/sigsetjmp ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
