by Ching de la Serna 03 Nov '09

03 Nov '09

Hi All, Is there a good way to handle Socket timeouts when transferring files to a server? ftp _ FTPClient openOnHostNamed: remoteHost. ....some code ftp putFileNamed: 'something; as: 'something'. <---error when connecting to remoteHost Socket>>connectTo: hostAddress port: port waitForConnectionFor: timeout "Initiate a connection to the given port at the given host address. Waits until the connection is established or time outs." self connectNonBlockingTo: hostAddress port: port. self waitForConnectionFor: timeout ifTimedOut: [ConnectionTimedOut signal: 'Cannot connect to ' , (NetNameResolver stringFromAddress: hostAddress) , ':' , port asString] Thanks in advance, Ching

This change restores the original menu structure, except that "open... ->morphic project" and "open... ->morphic world" are now displayed only if Morphic is present in the image, as per presumed intent of the prior change to #openMenu. Open concerns: The "open... -> keep this menu up" option, restored to the menu by this change, and "open... ->mvc project" options, which now attempts to open an mvc (not morphic) project, are both badly broken and will cause image freeze. The "open... ->file list" and "open... ->morphic world" selections (not related to this menu change) are also broken, probably for the same reason. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2009-November/001724.h… Name: SMBase-dtl.92 Ancestors: SMBase-nice.91 Fix spelling error in error message ============================================= http://lists.squeakfoundation.org/pipermail/packages/2009-November/001725.h… Name: CollectionsTests-nice.106 Ancestors: CollectionsTests-nice.105 Provide non regression tests for literal Array storeOn: (especially it must not loose bits when storing Float) ============================================= http://lists.squeakfoundation.org/pipermail/packages/2009-November/001726.h… Name: Graphics-nice.87 Ancestors: Graphics-nice.86 Rectangle storeOn: needs parenthesis ============================================= http://lists.squeakfoundation.org/pipermail/packages/2009-November/001727.h… Name: GraphicsTests-nice.17 Ancestors: GraphicsTests-nice.16 A test for Rectangle storeOn: =============================================

MVC scheduling broken in trunk
by David T. Lewis 01 Nov '09

01 Nov '09

Something is out of whack with MVC control scheduling in Squeak trunk. I am guessing that it may be something related to some earlier process scheduling changes, but I can't spot what is going wrong. Here are a couple of scenarios that illustrate the problem. Can anyone point me in the right direction to find the cause? Scenario 1: From an MVC project, evaluate: ProjectView open: MVCProject new. No window opens, and the image will not respond. Now do an <alt><period>, and Squeak exits with "scheduler could not find a runnable process" on the console. Scenario 2: In an MVC project, do <alt><period>. No debugger window opens. Do another <alt><period>, and Squeak exits with "scheduler could not find a runnable process" on the console. I first noticed this issue some time ago when I was checking low space interrupt handling (which is broken for the same reason I guess). Today I was looking at a problem in the MVC open->mvc project menu and see the same sort of symptoms, so I think this is an issue that has been in trunk for a while, most likely prior to any of the recent Project refactorings to separate MVC and Morphic. Thanks, Dave
