| Noteworthy changes in release 4.5.19 |
| ==================================== |
| |
| * Changes in behavior |
| * When command exits, strace now exits with the same exit status. |
| If command is terminated by a signal, strace terminates itself |
| with the same signal, so that strace can be used as a wrapper |
| process transparent to the invoking parent process. |
| When using -p option, the exit status of strace is zero unless |
| there was an unexpected error in doing the tracing. |
| (Addresses Fedora bug #105371 and Debian bug #37665) |
| |

| * Implemented decoding of new Linux syscalls: accept4, dup3, |
| epoll_create1, eventfd2, inotify_init1, pipe2, signalfd4. |
