| 2018-08-16 | Port scsh-process to CHICKEN 5 | Peter Bex | |
| Thanks to Vasilij Schneidermann for providing an initial patch. | |||
| 2018-04-21 | Make ">" redirect truncate existing files | Peter Bex | |
| Thanks to Joerg Wittenberger | |||
| 2018-01-26 | Fix ordering of (= x y) redirection EPF | Peter Bex | |
| Thanks to Diego "dieggsy" for pointing out this incongruity with scsh-process. | |||
| 2018-01-23 | Do not connect stdin to subprocess' stdout in run/file | Peter 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" | |||
| 2017-12-09 | Do not redirect stderr to stdin in fork/pipe. | Benutzer | |

| 2017-11-18 | Run signal handler in a separate thread | Peter 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. | |||
| 2017-11-18 | Perform trial wait with "nohang" set to #t when blocking | Peter 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. | |||
| 2017-11-10 | Also unmask (if needed) sigchld in the child process thunk | Peter Bex | |
| This would be otherwise kept in masked mode because the thunk is in the dynamic extent of the dynamic-wind. | |||
| 2017-11-10 | Don't unmask signal if the signal was already masked before forking | Peter Bex | |
| 2017-11-09 | Temporarily mask sigchld to avoid race condition in fork | Peter 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. | |||

| 2017-01-21 | Also export proc:pid (thanks to Joerg Wittenberger) | Peter Bex | |
| 2016-09-24 | Add proc:pid, proc?, signal-process and process-sleep for improved compat | Peter Bex | |
| Thanks to Joerg Wittenberger for the suggestion to add proc:pid and signal-process. | |||
| 2015-07-18 | Fix default output redirections to ignore stderr. | Peter Bex | |
| This is what scsh does as well, and is more like a regular UNIX shell. Thanks to Haochi Kiang for reporting the bug and providing a patch. | |||

| 2012-10-06 | Provide a new 'wait' procedure so we don't need to modify the type of ↵0.3 | Peter Bex | |
| process-wait, which could lead to trouble in user code when compiled with scrutiny and/or specialization. This procedure returns the values in a different order for ease of use. May be a bit confusing... | |||
| 2012-10-06 | Revert back to standard-extension and include a type declaration override ↵ | Peter Bex | |

| 2012-10-05 | Improve test for <<-redirection by making it less dependent on random ↵ | Peter Bex | |
| factors that determine process interleaving, ensuring it gets processed through the pipeline rather than on the same descriptor by mangling it through 'tr'. Fix <<-redirection by reopening output port on new descriptor and explicitly setting up the input port to the given fd in the parent process | |||
| 2012-10-04 | Reorder return values of process-wait; we shouldn't mess with that! | Peter Bex | |
