About cr and lf

by Stephane Ducasse

Hi guys While writing pillar code, I ended up using "stream cr" and it worries me to still expand usage of a pattern I would like to remove. Let us imagine that we would like to prepare the migration from cr. I was thinking that we could replace cr invocation by newLine so that after newLine could be redefined as Stream >> newLine self nextPutAll: OSPlatform current lineEnding what do you think about this approach?

Re: [Pharo-dev] Creating the smallest server runtime footprint

by Tim Mackinnon

Hi Mariano - Iâve looked at this again, and it was my fault - I was compiling in : fuelAccept: aGeneralMapper ^self explicitRequirement. Because when I looked at the Traits for fuel - this is what it had for TClass? - as Iâm not so clear on traits, what does this mean - as I had just assumed that I should flatten the Fuel methods for TCLass, TBehaviour and TClassDescription - but I think Iâve misunderstood what I should do (and I guess from Pavelâs comment - I should really look at why that initial method was missing as it sounds like it should have worked - so maybe its an order loading thing?). Thanks, for helping by the way - this is proving very instructional.

Re: [Pharo-dev] Creating the smallest server runtime footprint

by Tim Mackinnon

If Traits are supported then I must be doing something else wrong - maybe load order? (To be honest, I donât fully understand how traits work - but I will keep digging). It could be that my latest error (having just done Class compile: ââ¦. Missing method code â¦ â) is something deeper related to these traits methods not applying somehowâ¦ Iâll try a few things this morning. Itâs amazing how easily the image size jumps up when you add things though. With the original minimal v6 64bit image you sorted out for me I had a footprint of 21.6mb (image was 12mb). Now with the v7 image - and adding fuel and some S3 handling - it jumps up to 32.4mb (image is 15mb). I know that the S3 support has a lot of XML crud - but it seems quite astounding that this takes almost 8mb of code/objects. AWS loading (and hence response time) seems quite sensitive to the size of the package it has to load - although equally I wonder if there is also more #startUp/initalisation cost that is going on as well as when you get a warm lambda instance (so its not just loading your package) Iâm still not seeing the 400-500ms times but more 800-1000ms times. Its all quite interesting - and shows why the work behind a minimal image is very useful. Of course there is tiny-minimal (which I know you guys are after) and then there is small-server- minimal (which is realistically what Iâm after, so I can just focus on creating my app and just carefully load code and dependencies - but still have core server services like Fuel, and Git loading). Thanks for doing this work - as it brings a lot of useful things together.

OR is there something simple I can checkin and load locally to return that behaviour? (Personally I think it would make sense to allow remote loading - Iâm guessing Pharo itself as a core has everything it needs - but if you want to do any experimentation on the core and need remote packages, you would hit this too - so it feels a bit limiting). >>>>> >>>>> The dependencies in th baseline are supported but the support for most of external repositories (like package Metacello-GitBasedRepository) is loaded at the end of bootstrapping process in BaselineOfIDE. We should check/solve dependencies and move it into the minimal Pharo. For now you can try to load it by yourself or work with already prepared local clones of required repositories. >>>>> >>>>> -- Pavel >>>>> >>>>> >>>>> >>>>> >>>>> Tim >>>>> >>>>>> On 1 Aug 2017, at 10:06, Pavel Krivanek <pavel.krivanek(a)gmail.com <mailto:pavel.krivanek@gmail.com>> wrote: >>>>>> >>>>>> >>>>>> >>>>>> 2017-07-31 22:51 GMT+02:00 Tim Mackinnon <tim(a)testit.works <mailto:tim@testit.works>>: >>>>>> I wasnât clear on which image to retry - the https://ci.inria.fr/pharo/job/Pharo-6.0-Update-Step-3.2-Minimal/lastSuccess… <https://ci.inria.fr/pharo/job/Pharo-6.0-Update-Step-3.2-Minimal/lastSuccess…> one still shows as being last updated 7 days ago. >>>>>> >>>>>> The https://ci.inria.fr/pharo/view/6.0-SysConf/job/Pharo-6.0-Step-04-01-Configu… <https://ci.inria.fr/pharo/view/6.0-SysConf/job/Pharo-6.0-Step-04-01-Configu…> one gives me a mismatch error: This interpreter (vers. 68021) cannot read image file (vers. 6521). >>>>>> >>>>>> The https://ci.inria.fr/pharo/view/7.0/job/70-Bootstrap-32bit-Conversion/lastSu… <https://ci.inria.fr/pharo/view/7.0/job/70-Bootstrap-32bit-Conversion/lastSu…> one gives me a walkback when trying to run my install script : >>>>>> >>>>>> 25 UndefinedObject(Object)>>doesNotUnderstand: #addTo: >>>>>> 26 MCRepositoryGroup>>addRepository: >>>>>> 27 createRepository >>>>>> | repo | >>>>>> repo := self project createRepository: self. >>>>>> ^ MCRepositoryGroup default repositories >>>>>> detect: [ :each | each = repo ] >>>>>> ifNone: [ >>>>>> MCRepositoryGroup default addRepository: repo. >>>>>> repo ] in MetacelloRepositorySpec>>createRepository >>>>>> >>>>>> I think this is because the image doesnât support Metacello?
