Thanks to Diego "dieggsy" for pointing out this incongruity with scsh-process.
2018-01-23Bump version to 1.2.11.2.1Peter Bex
2018-01-23Do not connect stdin to subprocess' stdout in run/filePeter Bex
This would cause the REPL to exit after calling (run/file ...) because it reached EOF. Strangely this didn't cause any issues in the tests. Still not sure why this would be the case. Reported by Diego "dieggsy"

2017-11-18Tag 1.1.01.1.0Peter Bex
2017-11-18Run signal handler in a separate threadPeter Bex
This seems to be necessary so that condition-variable-broadcast! works when the signal handler is running in the same thread as the waiting thread.
2017-11-18Perform trial wait with "nohang" set to #t when blockingPeter Bex
We might have missed the one and only SIGCHLD event for the process we're about to wait for, so attempt to reap it before entering the condition variable wait loop. Just in case, we always do this when we're woken up, so that we can't accidentally miss the signal.
2017-11-10Tag 1.0.01.0.0Peter Bex
2017-11-10Also unmask (if needed) sigchld in the child process thunkPeter Bex
This would be otherwise kept in masked mode because the thunk is in the dynamic extent of the dynamic-wind.
2017-11-10Don't unmask signal if the signal was already masked before forkingPeter Bex
2017-11-09Tag 0.9.00.9.0Peter Bex
2017-11-09Temporarily mask sigchld to avoid race condition in forkPeter Bex
We do a fork, and immediately afterwards we insert a scsh-process object into the pending processes table with the pid of the newly created child process. However, sigchld may arrive in between the fork and the insertion of the scsh-process object into the pending process table. The sigchld handler will reap the child process and attempt to update the pending scsh-process object, but it can't find it yet because the insertion of this object into the table happens after the fork, thus losing the reaped child's exit status. Then, if the program waits for the process after that, we enter an infinite busy waiting loop that expects a sigchld to arrive and update the object through the table, but that never happens because the child has already been reaped.
