[Pharo-project] question about Issue 207: ImageSegment discoverActiveClasses strange error
by sheridan＠sheridan-mahoney.com Sept. 5, 2009

Sept. 5, 2009

- retrying in plain text... Hello, I am new to Pharo, and so have been perusing the bug database, and reading the recent posts in this list in order to investigate how to become involved in this community.  So far, I am very impressed! and encouraged that such a technically expert and friendly, supportive group is coelescing on this work effort! I have found a report that seems quite interesting, and have done some digging into the issue described here: http://code.google.com/p/pharo/issues/detail?id=207 ( ImageSegment discoverActiveClasses strange error ) and now I have a few questions I was hoping to get feedback on. It seems that, after using this method, some follow-up is required in order to reset the image back to a usable state.  And there are several options as to how to do that: 1) ImageSegment discoverActiveClasses. ImageSegment activeClasses size printString , ' classes were active out of ' , Smalltalk allClasses size printString. - this type of statment order will reset things ok.         2) ImageSegment discoverActiveClasses. ImageSegment  recoverFromMDFault. ImageSegment activeClasses. - it appears you still need the activeClasses method to reset the image (which wasn't entirely clear from the method comments - further comments may be useful here), otherwise there are classes with methodDictionaries that are set to nil. 3) ImageSegment discoverActiveClasses. Smalltalk at: #MDFaultDict put: Dictionary new. ImageSegment  recoverFromMDFaultWithTrace. Smalltalk at: #MDFaultDict. - this sequence of statments will give the user a report of active classes along with a description of how they came to be used. Similar to above o/w. 4)ImageSegment discoverActiveClasses. ImageSegment swapOutInactiveClasses. - there are at least 2 problems with this sequence - a)  initial result is a DNU - ThreadSafeTranscript(Object)>>doesNotUnderstand: #print    b) when you comment out the Transcript print statements to avoid the DNUs you get: ByteString(Object)>errorImproperStore I will be looking further into this issue, but was just wondering, firstly, is this a useful area to be spending time, and secondly, would it be appropriate to start a new bug, or update the old one?  Many thanks for your comments, Sheridan Mahoney

[Pharo-project] MC merge vs. load question
by Schwab,Wilhelm K Sept. 4, 2009

Sept. 4, 2009

Hello all, I might be having a problem querying a MySQL bit field, and want to try the latest ODBC package; it's been updated once since I built my current image, and there was mention of numeric mishaps, so it might go away. Is there a preferred way to get Monticello to update the package? I am specifically thinking of load vs. merge, but if there is anything else I should be asking, please let me know. Bill

[Pharo-project] runaway Pharo beta image
by Paul DeBruicker Sept. 4, 2009

Sept. 4, 2009

Hi - I have done something to my image and don't know how to fix it. When it opens it maximizes one of the processors and allocates a large amount of RAM to itself. When I attempt to run the Debug > Start profiling all Processes it crashes the vm after I move the mouse to the top of the screen. When I run Process allInstancesDo: [ :p | | rules | rules := ProcessBrowser nameAndRulesFor: p. rules second ifTrue: [ p terminate ] "1=name, 2=safe-to-kill, 3=safe-to-debug" ]. from here: http://wiki.squeak.org/squeak/1799 nothing changes. Printing 'ProcessBrowser new processList' in a workspace gives: a WeakArray(a Process in Delay class>>handleTimerEvent a Process in SystemDictionary>>lowSpaceWatcher a Process in [] in Delay>>wait a Process in WeakArray class>>finalizationProcess a Process in nil a Process in ByteString(String)>>encodeOn: a Process in [] in BlockClosure>>newProcess) And the VM statistics are: uptime 0h8m53s memory 1,055,051,120 bytes old 1,050,497,028 bytes (99.6%) young 83,708 bytes (0.0%) used 1,050,580,736 bytes (99.6%) free 4,470,384 bytes (0.4%) GCs 4,999 (107ms between GCs) full 3 totalling 18,400ms (3.0% uptime), avg 6133.0ms incr 4996 totalling 120,999ms (23.0% uptime), avg 24.0ms tenures 112 (avg 44 GCs/tenure) Are there other things I can do to get it back under control or should I just save everything in some MC repositories and set up a new image? I'm reluctant to do that now because I don't know what I did to create the situation I'm in. Thanks for your help Paul

[Pharo-project] Added package SLICE-RemoveReferencesToReadStreamOn-PeterHugossonMiller.3 to PharoInbox
by Peter Hugosson-Miller Sept. 4, 2009

Sept. 4, 2009

Hi there, This is my first contribution to PharO :-) I've followed the instructions on the "How to Contribute" page, and there is now a bunch of packages, and a SLICE-package that depends on all of them (named in the subject of this message) in the PharO inbox. One of the packages (KernelTests-PeterHugossonMiller.142.mcz) I have managed to miss the log message, but otherwise I believe I have done everything correctly. I attach screenshots of the TestRunner results run before and after my changes. Please could someone review the changes and let me know how I did. -- Cheers, Peter *Before my changes:* [image: Before_RemoveReferencesToReadStreamOn.png] *After my changes:* [image: After_RemoveReferencesToReadStreamOn.png]

[Pharo-project] FFI meets 74 bits - there be dragons here??
by Schwab,Wilhelm K Sept. 4, 2009

Sept. 4, 2009

Hello all, So far, I am one for two on getting ODBC to work on my 64 bit Ubuntu system. I'm using a pre-production (the only option we were given by our IT guys) Cisco vpn that does not support 64 bit systems; enter a 32 bit vpn and some copied libraries. After that fun, I have been able to get isql (unixODBC test utility) to see a MySQL server I have living on a blade machine. That much works. My Pharo image seems unable to talk to it, and I am wondering whether it might be because the library is 64 bit - please excuse me if that's just plain stupid. Of course, so was installing the 64 bit OS<g>, but I figure there will not be an option some day, so I'm trying to get my bad news early. Any ideas about how to proceed? I'm thinking of subclassing ODBCLibrary and tweaking the types (something on the net addresses some changes) to see if I can get some success and then keep going as needed. Does that sound reasonable? Any better ideas? FreeTDS is letting me down talking to a SQL server machine. If anyone has set that up successfully, I would greatly enjoy knowing what you did. Bill
