bug#30460: [PATCH] Remove :stop key from make-process. |
Date: |
Fri, 19 Apr 2019 13:06:43 +0200 |
This has never worked and caused issues such as Bug#30460.
* src/process.c (Fmake_process): Don't accept :stop key any more.
(syms_of_process): Define needed symbol 'null'.
* test/src/process-tests.el (make-process/stop): New unit test.
* doc/lispref/processes.texi (Asynchronous Processes): Remove :stop
key from manual.
