Sabine,
I did not yet tested OSProcess but with OSSubprocess (in 5.0) I cannot
reproduce the issue:
*Polling strategy works:*
Delay delaySchedulerClass: DelayMillisecondScheduler.
20 timesRepeat: [OSSUnixSubprocess new
command: 'echo';
arguments: {
' };
redirectStdout;
*runAndWaitPollingEvery: (Delay forMilliseconds: 50) retrievingStreams:
true onExitDo: [*
:process :outString :errString |
Transcript show: outString;cr .
].
].
*Semaphore-based (child watcher) works:*
Delay delaySchedulerClass: DelayMillisecondScheduler.
20 timesRepeat: [OSSUnixSubprocess new
command: 'echo';
arguments: { 'Hi There' };
redirectStdout;
*runAndWaitOnExitDo:* [
:process :outString :errString |
Transcript show: outString;cr .
].
].
*Using shellCommand: (bash) instead of #command: and #arguments: does work
too:*
Delay delaySchedulerClass: DelayMillisecondScheduler.
20 timesRepeat: [OSSUnixSubprocess new
*shellCommand: ('echo "Hi there"');*
redirectStdout;
runAndWaitOnExitDo: [
:process :outString :errString |
Transcript show: outString;cr .
].
].
