Package EXTERNAL-PROGRAM: SYS:PID-EXIT-STATUS no more available in Lispworks 7

Dear LW Gurus!

While loading package EXTERNAL-PROGRAM (see https://github.com/sellout/external-program) - I used Quicklisp to load this package,

I get the following error:

**++++ Error between functions:

Symbol "PID-EXIT-STATUS" not found at all in the SYSTEM package.

; (METHOD EXTERNAL-PROGRAM:PROCESS-P (EXTERNAL-PROGRAM::EXTERNAL-PROCESS))

The relevant code section is:

(defmethod process-status ((process external-process))

(let ((status-code (sys:pid-exit-status (external-process-process-id

process))))

(values (if status-code :exited :running) status-code)))

I would like to make this available on LW7 - but so far could not find a more or less drop-in replacement for this call. I am sure I am missing something … Any help / hint / advice really appreciated. Thanks for your help.

Kind regards

Frank

Re: Package EXTERNAL-PROGRAM: SYS:PID-EXIT-STATUS no more available in Lispworks 7

I discovered the same thing some time back, and contacted Lispworks support about it. The response I got was

: Thanks for the report -- the change is documented in the Release Notes 15.20.6
: (http://www.lispworks.com/documentation/lw70/RNIG/html/readme-151.htm#marker-972462)
: but was missing from the index so is not easy to find.

: LispWorks 7.0 has sys:pipe-exit-status for pipes.

: We don't support working with PIDs inside Lisp because the SIGCHLD handler
: automatically reaps the exit status and hence the PID will no longer be
: unique.

It should be relatively easy to make the necessary changes to code that uses sys:pid-exit-status.

Here is an example that has both lispworks6 and lispworks7 versions side by side: https://github.com/ExaScience/elprep/blob/master/io-utils.lisp

Look for “(defstruct process”, “(defun run-program”, and “(defun process-close”.

Re: Package EXTERNAL-PROGRAM: SYS:PID-EXIT-STATUS no more available in Lispworks 7

May I recommend uiop:run-program instead of external-program?

If you're doing only synchronous calls, it's a slam dunk better.

If you're doing asynchronous calls, however, it is admittedly mostly
undocumented.
