All hang on line: OSProcess waitForCommand: 'touch /tmp/delete.me'.

UnixProcess>>waitForCommand:        <snip>        [proc runState == #complete] whileFalse: [d wait]. <-- infinite loop

This may be related to another problem I was having with CommandShell:  p := PipeableOSProcess command: '/bin/echo this is a test'.  result := p output. "hangs"

ExternalUnixOSProcess>>isComplete  ^ self runState == #complete from PipeableOSProcess(PipeJunction)>>isComplete from PipeableOSProcess(PipeJunction)>>outputOn: from PipeableOSProcess(PipeJunction)>>output

sounds like VM cannot detect that child process are finished (complete).

Hi Sean, If you have a chance, could you please run the following and post your results from the transcript? Thanks a lot. Transcript clear. { 'CommandShell versionString ==> ', CommandShell versionString. 'OSProcess versionString ==> ', OSProcess versionString. OSProcess accessor osppModuleName asString. 'OSPP versionString ==> ', OSProcess accessor osppModuleVersionString asString. OSProcess accessor aioModuleName asString. 'AIO plugin versionString ==> ', OSProcess accessor aioVersionString asString. OSProcess accessor xdcpModuleName asString. 'XDCP versionString ==> ', OSProcess accessor xdcpVersionString asString } do: [:e | Transcript cr; show: e] For reference, on a Linux platform with interpreter VM you might get results like this: CommandShell versionString ==> 4.4.15 OSProcess versionString ==> 4.4.2 UnixOSProcessPlugin 24 May 2011 (e) OSPP versionString ==> 4.4.3 AioPlugin 24 May 2011 (e) AIO plugin versionString ==> 2.2.4 XDisplayControlPlugin 24 May 2011 (e) XDCP versionString ==> 2.1.6 Thank you, Dave On Fri, Jun 03, 2011 at 04:04:35AM -0700, Sean P.

***********************OSProcess test results are...

UnixProcessTestCase - it seems like tests that fork (e.g. UnixProcessTestCase>>testClassForkHeadlessSqueakAndDo) hang forever and then things that were working don't work anymore (there is often a warning "forkSqueak requires XDisplayControlPlugin" before something bad happens, but it seems like it gets screwed up whether you hit proceed or abandon). This seems to be the major issue.

All pass in OSPipeTestCase, UnixProcessFileLockTestCase, UnixProcessUnixFileLockingTestCase, UnixProcessWin32FileLockingTestCase

UnixProcessAccessorTestCase Failures: testChDir testIsExecutableForUserInGroup testIsReadableForUserInGroup testIsWritableForUserInGroup

AioEventHandlerTestCase: Errors: '#(''AioEventHandlerTestCase>>#testPrimAioModuleName''

Failures: ''AioEventHandlerTestCase>>#testFileReadableEvent'' ''AioEventHandlerTestCase>>#testFileWritableEvent'' ''AioEventHandlerTestCase>>#testSuspendAioForSocketReadableEvent'' ''AioEventHandlerTestCase>>#testHandleForFile'' ''AioEventHandlerTestCase>>#testEnableHandleAndDisable'' ''AioEventHandlerTestCase>>#testSocketReadableEvent'' ''AioEventHandlerTestCase>>#testHandleForSocket'' ''AioEventHandlerTestCase>>#testPrimAioModuleVersionString''

All pass in ExpressionEvaluatorTestCase, InternalPipeTestCase, PipelineEventsTestCase, ShellSyntaxTestCase

PipeableOSProcessTestCase testForkHeadlessSqueakReadAndWriteReferenceStream, testForkSqueak, testForkSqueakReadAndWriteReferenceStream, testForkSqueakReferenceStream give warning "forkSqueak requires XDisplayControlPlugin" testForkHeadlessSqueak, testForkHeadlessSqueak2, testForkHeadlessSqueakReferenceStream give same warning, and then hang

CommandShellTestCase - all pass, except testPipeline65 fails. Sean

Thanks Sean, Some of the VMs for OS X were accidentally built with an out of date OSProcessPlugin (OSPP). It looks like you have one of them. You have version 4.2.4 of OSPP which was from April 2007, and does not contain many necessary updates and fixes. Dave

Aha! That VM came directly from http://www.squeakvm.org/mac/. Where do I get the right one?

I am not a Mac user, so I don't know if I am giving you the right information here. But I think you said you are using a 4.2.5 VM, which according to http://squeakvm.org/mac/ would be for older Mac systems "mostly for EToys which has to run on really old macintosh computers that you find the USA school system". If I remember correctly, there are no plans for further updates to that VM (Esteban could say better than me of course). If it is important for you to have OSProcess on the older Mac systems, I can raise the question on the vm-dev list. Dave

From http://forum.world.st/looking-for-feedback-on-Cocoa-Cog-MT-VM-td3534230.html : Esteban Lorenzano wrote:

What is definitively true, is the fact that there are a lot of machines who needs to use a 4.x series (in mac versions), and a lot of legacy code who will be using this "old" vm too... and because of this, 4.x series will be around a long time.

With Cog 5.8b12, I got warnings like "process accessor module not available". And I mentioned the hanging tests with the Cocoa 5.7.4.1 in my last post. So there seems to be issues with all the Mac VMs. David T. Lewis wrote:
