A small convenience update to OSProcess/CommandShell
by David T. Lewis 09 Oct '14

09 Oct '14

I have updated OSProcess/CommandShell with some changes that allow PipeableOSProcess to be used more conveniently for executing commands on a Unix/Linux/OSX system. You can now run a simple command without worrying about closing (pipe) file handles or other special handling. For example: ( PipeableOSProcess command: 'ls -l' ) output Explanation: PipeableOSProcess was originally designed to support command pipeline execution within a CommandShell. In that scenario, the command shell handles all setup and cleanup of pipe handles. In practice, PipeableOSProcess turns out to be useful for simple command execution with input and output pipes connected to the image. The updates to PipeableOSProcess class>>command: add the necessary setup and cleanup that would otherwise have been done by the command shell. OSProcess and CommandShell are on SqueakMap (select the "head" version to get the latest), or from the squeaksource repository at: http://www.squeaksource.com/OSProcess http://www.squeaksource.com/CommandShell Dave

.mcd to .mcz (urgent)
by Eliot Miranda 09 Oct '14

09 Oct '14

Hi All, so *how* do I ensure I have a .mcz when there appears to only be a .mcd? I'm talking about trying to get 'Kernel-ul.875.mcz' from trunk when Kernel-ul.875(eem.872).mcd appears to be on offer. If I try MCCacheRepository default storeVersion: (trunk versionNamed: 'Kernel-ul.875.mcz') I *do not* get a 'Kernel-ul.875.mcz' in my cache repository. I'm f*&^%d until I can get this working. help, please! -- best, Eliot

Debugger hiccups
by Balázs Kósi 07 Oct '14

07 Oct '14

Hi, Today I came across two nuisances in the debugger: The first one is, that if you try to evaluate code in a debugger started from another debugger, you'll get an MNU: MessageAsTempNode>>beMethodArg. The other one is a tad more dangerous, so don't try it in an image dear to you: If you try to debug one of the following expressions: "nil", "-1", "0", "1" and "2" your image hangs. After interrupting it you get infinite debuggers with the message: "subscript is out of bounds: 2". The stack shows just one line: MethodContext(Object)>>error: I did not investigate any further yet. Cheers, Balázs
