Re: [Pharo-dev] Git breaks Monticello's version numbers

by Ben Coman

Could a pragmatic fix be simply... if the first-generated MC version number is greater than 10000, then re-generate the MC version number based off the latest version number in the MC repository. But the bigger question is for... v1(MC) --> v2(git) --> v3(git) --> v4(git) --> v5(MC) what about all the intermediate commits? Do v2, v3, v4 need to make it into MC? Its the same sort of problem if you were maintaining two separate MC repos in sync, not specifically an Iceberg problem. So as Joel describes in "Let me go Back" regarding the tipping point for Excel to overtake Lotus123, perhaps we a (separate) tool in the default Image that migrates from git back to MC, as well as from MC to git. https://www.joelonsoftware.com/2000/06/03/strategy-letter-iii-let-me-go-bac… cheers -ben On Sat, May 13, 2017 at 10:42 PM, Thierry Goubier <thierry.goubier(a)gmail.com> wrote: > Le 13/05/2017 Ã 16:17, Esteban Lorenzano a Ã©crit : >> >> >>> On 13 May 2017, at 15:51, Thierry Goubier <thierry.goubier(a)gmail.com> >>> wrote: >>> >>> Le 13/05/2017 Ã 15:43, Esteban Lorenzano a Ã©crit : >>>> >>>> >>>> >>>>> On 13 May 2017, at 13:16, Yuriy Tymchuk <yuriy.tymchuk(a)me.com> >>>>> wrote: >>>>> >>>>> Iâm not a bit expert, but if you donât use âmetadatalessâ format >>>>> everything works fine with monticello.

In fact my test was broken an in addition the debugger does not show the top frame and it took me a while to see that I should always scroll to be the stack. And I was always only seeing this mustBeABoolean.

Hi, I am not quite sure where the issue is because I cannot seem to reproduce the problem. I try this Playground script: Object subclass: #ABC instanceVariableNames: '' classVariableNames: '' package: 'ABC'. ABC compile: 'doesNotUnderstand: aMessage "support sending message to access properties" | selector | selector := aMessage selector. self halt: aMessage selector. ^ selector isUnary ifTrue: [ (self hasPropertyAt: selector) ifTrue: [ self propertyAt: aMessage selector asSymbol ] ifFalse: [ super doesNotUnderstand: aMessage ] ] ifFalse: [ selector numArgs = 1 ifTrue: [ self propertyAt: aMessage selector allButLast asSymbol put: aMessage argument ] ifFalse: [ super doesNotUnderstand: aMessage ] ]'.

How to be able to get a debugger inside DNU

by Stephane Ducasse

Hi In the past it was possible to step throw such code and now we cannot anymore because of a smart trick. I should say that I hate when we break the reachibility and understandibility of the system. So why I cannot get a debugger opens after the halt: ? How do I get that ? Now I will put traces: super cool! Stef doesNotUnderstand: aMessage "support sending message to access properties" | selector | selector := aMessage selector. self halt: aMessage selector. ^ selector isUnary ifTrue: [ (self hasPropertyAt: selector) ifTrue: [ self propertyAt: aMessage selector asSymbol ] ifFalse: [ super doesNotUnderstand: aMessage ] ] ifFalse: [ selector numArgs = 1 ifTrue: [ self propertyAt: aMessage selector allButLast asSymbol put: aMessage argument ] ifFalse: [ super doesNotUnderstand: aMessage ] ]
