Is this some cleanup that happened in Pharo and that requires a new package to be loaded? > We started to clean up ImageSegments in 1.3. Most of ImageSegments is there (and even cleaned and fixed by Mariano while he analyzed the code). We removed all of ImageSegment code in the image in 1.4, though. After *very* careful analysis *and* implementing a better replacement... (Fuel). The #saveImageSegments when saving the Image itself I removed in 1.3 already (after sending a mail to the list to ask if anyone uses it). The idea was that on image save, if image segments are written to disk, it would copy them over if you rename the image on save: saveImageSegments: previousFullImageName "This method is used for example when you save an image with another name. In this case, if there are segments written to files and there are ImageSegment instances, then it copies the file from the previous image location, to the new one. It is like a backup of the segment files when renaming an image. " | haveSegs oldImageSegDir theClass newImageSegDir | "If the class does not exist or has no instances, it has no sense to backUp the segments." self areThereImageSegments ifFalse: [ ^ self ]. theClass := Smalltalk globals at: #ImageSegment. oldImageSegDir := theClass segmentDirectoryFrom: previousFullImageName. newImageSegDir := theClass segmentDirectory. "create the folder" oldImageSegDir fileNames do: [ :theName | | imageSegmentName "copy all segment files" | imageSegmentName := oldImageSegDir pathName , FileDirectory slash , theName. newImageSegDir copyFileWithoutOverwriteConfirmationNamed: imageSegmentName toFileNamed: theName ] So if your image has no image segments, than it's ok to just remove the call.

Yes, but Adrian is on Holidays in India and I can't change it (at least I have not found out how).

[Pharo-project] new Cog VMs available [please read]
by Eliot Miranda Sept. 23, 2011

Sept. 23, 2011

...in http://www.mirandabanda.org/files/Cog/VM/VM.r2493/. These VMs are not much changed from the 2487 VMs, BUT the 2487 VMs introduced a bug while providing faster doesNotUnderstand: processing. These 2493 VMs contain code to help identify that bug. If you're already using a 2487 VM or newer /please/ upgrade to these 2493 VMs asap. I want to see C stack backtraces from these VMs whenever they crash. Typically the VMs produce a crash.dmp file somewhere in the file system (may be / on Mac OS, may be in the directory containing the VM or the current directory on other OSs, but it will be called crash.dmp, and on Mac OS info will be printed to the console or to a crash report window). The C backtrace part of things looks like this on windows: Stack backtrace: [004193EA] ??? + 4297706 in CogCode [00442337] ??? + 4465463 in CogCode [00442685] ??? + 4466309 in CogCode [00583018] ??? + 5779480 in CogCode [0040124B] ??? + 4198987 in CogCode [00401298] ??? + 4199064 in CogCode [7C816FE7] RegisterWaitForInputIdle + 73 in kernel32.dll [7C913BA7] RtlDosApplyFileIsolationRedirection_Ustr + 1824 in ntdll.dll this on Mac C stack backtrace: 0 nsvm 0x00038689 reportStackState + 105 1 nsvm 0x0003893e sigsegv + 110 2 libsystem_c.dylib 0x9b2e259b _sigtramp + 43 3 ??? 0xffffffff 0x0 + 4294967295 4 nsvm 0x0008b2a5 sufficientSpaceAfterGC + 69 5 nsvm 0x0008d11d primitiveNewWithArg + 221 6 ??? 0x068b9899 0x0 + 109811865 7 nsvm 0x00098d10 initStackPagesAndInterpret + 512 8 nsvm 0x0002c530 EventLoopEventHandler + 16 Etc. So please feel free to email me the crash.dmp's and/or the C backtraces of any crashes you have with 2493 VMs. Hopefully I'll track down this regression quickly. For the curious, what's the bug? I don't know yet. The symptom is that very rarely the inline cache linking machinery for MNU PICs relinks the call of an MNU PIC to the address 0x00000013, which causes a crash when the call is next executed, long after the bug bit. These VMs contain code that will raise an error when the relinking attempt is made, which should reveal the bug. Here's the 2493 readme: CogVM binaries as per VMMaker.oscog-eem.125/r2493. Add callsite link/relocate checks to catch the call 0x00000013 MNU callsite relinking bug. Reduce the size of the simStack to something proportional to LargeContextSize. In the Newspeak VM, don't cd to the image's directory on win32. Fix off-by-one error in Win32OSProcessPlugin>primitiveGetCurrentWorkingDirectory so it doesn't include an erroneous trailing null. Fix the 1Gb allocation bug. -- best, Eliot

[Pharo-project] Switching windows using CMD+right/left
by Benjamin Sept. 23, 2011

Sept. 23, 2011

He guys, I really would like to know if someone is using the shortcut cmd+right/left to switch between windows into Pharo. Because right now on Mac, this shortcut is used to jump to the begin/end of the line, when fn+right/left jump to the begin/end of the file. It means that per day, I lost 15 minutes (and my nerves ^^) because in eclipse I just jump at the end of the file instead the end of the line ( and then I have to scroll back... frustrating), and when I code in pharo, I use cmd, and then it swap the window. And the worst part is that cmd+right followed by cmd+left do NOT bring you back to the original window, so I am lost and it frustrates me a lot ^^ So I would like to propose to change the shortcut binding to be a bit consistent between pharo and mac (could windows/linux user tell me how it works on those platforms ?), and use ctrl+tab to switch between inner windows (like in a web browser or cmd+` like in Mac OSX Please tell me your experience about this, cause http://www.dailymotion.com/video/x4m18_queen-i-m-going-slightly-mad_news ;) Ben

[Pharo-project] Two objects with same hash

If you are on Windows you can use Microsofts GUID. I wrapped them in http://www.squeaksource.com/COM.html as class COMGUID. They are unique in time and location so you need no additional date. If I remember correctly the UUID plugin for Windows used them directly as the underlying generation algorithm ... I also expected UUIDs (for instance if generated on Mac or Linux) as unique in time and location so it should not be possible to generate the same value at the same time on two different computers.
