New Cog VMs available
by Eliot Miranda Oct. 25, 2014

Oct. 25, 2014

...at http://www.mirandabanda.org/files/Cog/VM/VM.r3114/. CogVM binaries as per VMMaker.oscog-eem.913/r3114 Spur: Fix baaaad bug in checking for still-married contexts in Spur. One *cannot* simply follow what is assumed to be the frameContext field of what is presumed to be a context. On Spur we need to *know* whether we have a valid frameContext field, and for that we have to know there is a valid frame. So refactor, moving isFrame:onPage: from StackInterpreterPrimitives to StackInterpreter, and use it to validate the frame pointer of a maybe married context before testing the context for being forwarded. All: Avoid cogging methods containing unknown bytecodes early in scanMethod. Use a hack to avoid a test on the common path. Fix assert fail cases in ceInterpretMethodFromPIC:receiver: Both of these together fix assert fails due to cogging methods containing unknown bytecodes. Spur: Implement image segments. Use Igor's idea of splitting the computation of the transitive closure from the writing of the image segment for simplicity, even if the two are together into a single primitive for backwards-compatibility. All: Rewrite the two image segment primitives to pass back an error code on failure, and rewrite the (New)ObjectMemory code to answer informative failure codes. Print slots of word objects in longPrintOop: Fix parenthesization bugs in validation code in some Alien plugin primtiives. Make findClassContainingMethod:startingAt: et al robust in the face of faulted-out classes (nil method dictionaries). Include the AioPlugin in the Newspeak linux VMs; recent reports indicate it's essential to good performance in recent versions of OSProcessPlugin. Unix startup script: Quote the LD_LIBRARY_PATH setting to tolerate directory names with spaces. -- best, Eliot

Weird rehashing problem
by Max Leske Oct. 25, 2014

Oct. 25, 2014

Hi I have a rather strange problem with rehasing that occurred simultaneously multiple times on the same day but not since. Luckily Iâve saved an image with the debugger in it. The mean thing is: that doesnât help me at all because from what I can tell either the Debugger is broken or thereâs a VM problem. Note: The image is a Pharo 1.3 image. The problem occurred on two different VMs independently, an NBCog VM (Croquet Closure Cog VM [CoInterpreter VMMaker-oscog-EstebanLorenzano.166] 21.0) and a Squeak VM (Squeak3.10.2 of '5 June 2008' [latest update: #7179]). The operation during which this happened was the loading of an ImageSegment (in both instances). Hereâs what happened. I got a SubscriptOutOfBounds error during rehashing of a Dictionary. When I look at the debugger itâs clear why the exception got signaled but not how that situation could ever happen. These are the top three contexts on the stack: Array(Object)>>errorSubscriptBounds: Array(Object)>>at:put: CBConfiguration(Dictionary)>>noCheckAdd: This is the #noCheckAdd: methodâ noCheckAdd: anObject "Must be defined separately for Dictionary because (self findElementOrNil:) expects a key, not an association. 9/7/96 tk" array at: (self findElementOrNil: anObject key) put: anObject. tally := tally + 1 and hereâs #at:put: where the exception is signaled: at: index put: value <primitive: 61> index isInteger ifTrue: [self class isVariable ifTrue: [(index >= 1 and: [index <= self size]) ifTrue: [self errorImproperStore] ifFalse: [self errorSubscriptBounds: index]] <âââ signaled ifFalse: [self errorNotIndexable]]. index isNumber ifTrue: [^self at: index asInteger put: value] ifFalse: [self errorNonIntegerIndex] Hereâs the weird thing: according to the debugger âarray' in #noCheckAdd: IS NOT THE SAME INSTANCE as âselfâ in #at:put:!!!!!! ????????? When I look at the pointers to both arrays, the correct one is pointed to by the dictionary while the other is only being referenced by the exception context: Bad array: 1: SubscriptOutOfBounds: 88 2: Array(Object)>>errorSubscriptBounds: 3: Array(Object>>at:put: 4: an Inspector â¦ Good array: 1: aCBConfiguration(size 107) I really have no clue how this could have happened. Iâd appreciate any thoughts you might haveâ¦ Cheers, Max

Monticello on local network server
by Dario Trussardi Oct. 25, 2014

Oct. 25, 2014

Hi, i work with Pharo 1.4. I need to manage a packages on a local server with Monticello http repository. I configured the Monticello repository with: MCHttpRepository location: 'http://www.server1.com/RepositoryDTR/' user: '' password: '' And configured the local DNS to redirect the request on the IP server and configured the lighttpd on the server to redirect the /RepositoryDTR/ path on the specific server path. Now when i open the repository with Monticello i can see the hold *.mcz package into server 1 /RepositoryDTR/ path I found the error: ZnHttpUnsuccessful: 404 Not Found when i save, with Monticello browser, a new package version on the server. I need to do some initialization before use a remote http ? Thanks for any considerations, Dario This is the stack relative of the error.

Playground/Rubric bracket highlighting in the System Browser
by Peter UhnÃ¡k Oct. 24, 2014

Oct. 24, 2014

Hi! Playground has a very nice feature that it highlights matching bracket. I guess Rubric does it. Is this something that is planned to be implemented into the System Browser editor? That would probably mean replacing the PluggableTextMorph, but I don't know if there are any problems with doing so. Also is there a keyboard shortcut for jumping to the matching brace/bracket?

Take care with Package renaming in Pharo 3/4
by Torsten Bergmann Oct. 24, 2014

Oct. 24, 2014

Take care when renaming a package in Pharo: when you rename by just changing upper/lower case the package and code vanishes away. https://pharo.fogbugz.com/f/cases/14310/Renaming-a-package-just-by-changing… This is in Pharo 4.0 (up to 40324) and 3.0 (up to 30858). Nice way to get rid of fresh written code, even change sorter, changes file or recover lost changes will not help anymore :(

.source file

Oct. 24, 2014

For information, a iStoa user reported to me this problem, related to a Pharo regression I already discussed about here https://bugs.launchpad.net/istoa/+bug/1384649 I see this related bug report: https://pharo.fogbugz.com/f/cases/10464/Always-warn-when-sources-or-changes… So what is the plan regarding source code, will we be forced to ship it. It is untrue disk space is cheap, especially for desktop or tablet application. Hilaire -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

RemotesManager Fishiness
by Sean P. DeNigris Oct. 24, 2014

Oct. 24, 2014

[rant] This is a weird class! It's protocol seems convoluted to me (even though it only contains one operation!). The standard dialog #actionBlock: is eschewed for #selectedChangedBlock:, which lets you know every time an item is checked or unchecked. I'm not clear on the use case for that verbose level of updating. I would think you'd mostly be interested in the final state once the dialog was accepted. In addition, there is a #selectedRemotes instVar, but it never gets updated and has no getter. Maybe I'm just not getting it, but it seems like something was quickly hacked together as an experiment to serve an immediate purpose without much design thought. While I love new features, this worries me because it sounds very familiar and three forks may be one too many ;) Maybe we should have a more formal code review procedure for shiny new features (non-bug fix/enhancement)? [/rant] 14303 RemotesManager: Make more generally useful https://pharo.fogbugz.com/default.asp?14303 Initial slice incoming... ----- Cheers, Sean -- View this message in context: http://forum.world.st/RemotesManager-Fishiness-tp4786315.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
