CommandShell 4.6.22

Accommodate Squeak themes. Because CommandShellTranscript is a model, but does not inherit from Model, implement #windowColorToUse to delegate to a Model for selecting a default color.

When forking an image with PipeableOSProcess, close unused pipe handles for the connecting pipes immediately in both child and parent, otherwise testing #atEndOfFile can fail in one image beccause of the open handle in the other image.

In tests, add a #flush because C runtime may require it. Use upToEndOfFile and remove the now unneeded delay.

CommandShell 4.6.10

RemoteTask (poor man's multiprocessing): Add support for the Magma serializer. A RemoteTask can communicate its results to the parent image using any of the supported serializers (#referenceStream, #fuel, or #magma). See the class initialization methods for RemoteTask.

A RemoteTask represents a block to be evaluated in a headless Squeak child process. The results of evaluating the block are returned to the sender through a serialization stream on an OS pipe. Asynchronous event notification may be used to signal completion of remote processing.

OSProcess 4.5.11, CommandShell 4.6.8
Fixes by Sean DeNigris for win32 support in PipeableOSProcess (CommandShell package)

Date: Fri, 27 Dec 2013 10:09:37 -0800 (PST)
From: "Sean P. DeNigris"
To: squeak-dev@lists.squeakfoundation.org
Subject: [squeak-dev] Fix: OSProcess on Windows

I made a small fix for MNU #defaultShellPath, which has been reported a few times. I didn't have repo write access, so I committed to
http://smalltalkhub.com/#!/~SeanDeNigris/SeansOutbox . Sometimes on Windows (e.g. seemingly when there are quoted command line arguments), the argument to #waitForCommand: and command: must be wrapped in $". I don't think there is any harm in always doing this (on Windows), but wanted to get feedback from Dave first...

PipeableOSProcess are now working, with two restrictions:
- no access to stdout
- argument to #waitXyz: may have to be surroundedByDoubleQuotes

CommandShell 4.5.5

Address process synchronization issues exposed by unit tests.

An error pipeline stream is shared by multiple process proxies, so do not raise an error in PipeJunction>>closeErrorPipeline if the close fails.

Add a short (10 ms) delay ProxyPipeline>>value after each proxy is started in order to permit associated (Smalltalk) processes to be scheduled to service that proxy. When using AIO event driven streams, this permits a BufferedAsyncFileReadStream to start its event handler process.

CommandShell 4.5.0

Update RemoteTask to support asynchronous task completion notification. Eliminate redundant buffering of input stream, and read the result object directly from the pipe reader upon notification of data available from the remote image. Processing no longer waits for remote image exit, and does not read remote data into intermediate buffers and streams.

Add #do:whenComplete: to schedule a remote task (image forked in separate OS process) with results handled in a completion block. The supervisory Squeak image carries none of the processing load during remote task execution.

Support forkSqueak with AIO event handling to provide notification of data available from remote Squeak.

CommandShell 4.4.8

Return to publishing full CommandShell package. Splitting CommandShell into individual packages is nice for modularity, but not good for version tracking. The individual subpackages will continue to be published separately along with the full CommandShell package.

Changes since CommandShell 4.4.4:

CommandShell 4.4.8
Change RemoteTask>>result to poll for child completion to avoid spin wait on pipe read. Better solution would be to change ReferenceStream reading to work with non-positionable stream.

CommandShell 4.4.7
Fix a race condition in PipeableOSProcess accessProtect that led to intermittent blocking of the OSProcess grimReaper process when running test suite.

CommandShell 4.4.6
Pharo pretends to be unaware that it #isMorphic, so implement a workaround in CommandShell class>>isMorphic.

Handle Pharo variances for window spec on class initialization

Fix handling of WindowColorSpec not present

CommandShell 4.4.5

Do not open a command shell window in CommandShell class>>initialize (instead use CommandShell class>>openWithHelp in SAR postscript).

Work around some Pharo differences:
- Preference mechanism is different
- Window color specs replaced by some other mechanism.
- World menu registration requires pragmas, will not work in e.g. Squeak 3.8

CommandShell 4.4.4

Add RemoteTask for remote block execution.

"RemoteTask do: [2 + 2]"

A RemoteTask represents a block to be evaluated in a headless Squeak child process. The results of evaluating the block are returned to the sender through a reference stream on an OS pipe.
