Pharacloud Seaside Rest exception when opening the application
by Lionel Akue July 14, 2017

July 14, 2017

Hello everyone, I have a fully working Seaside MDL application in locale. But when I load the image (pharo 6) to ephemeric cloud and try to open the application, I get: WAArgumentNotFoundError: argument "aPhonenumberString" was not found in #(#arg1 #arg2) Debug Full Stack thisContext WAFullPlaceholderPathMatch class(WAMatch class)>>argument:notFoundInd: self WAFullPlaceholderPathMatch thisContext [ :arg3 | | tmp1 | arg3 isDigit ifFalse: [ tmp1 := arg2 indexOf: arg1. tmp1 isZero ifTrue: [ ...etc... self WAFullPlaceholderPathMatch thisContext ByteString(SequenceableCollection)>>do: self 'aPhonenumberString' When I use an Pharo 5 image, the Seaside welcome page doesn't show up. And I get a '500 internal server error'. Could you help fixing this? thanks, Lionel

VoyageMongo not working in Pharo 6?
by kmo July 14, 2017

July 14, 2017

I just had a quick tryout of VoyageMongo in Pharo 6 and VOMongoRepository>>save:anObject fails because UUIDGenerator does not have the method makeSeed. UUIDGenerator >> makeSeed was present in pharo 5. It's not there in pharo 6. I installed from the Catalog browser where VoyageMongo is listed as being OK for pharo 6. -- View this message in context: http://forum.world.st/VoyageMongo-not-working-in-Pharo-6-tp4954843.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Peristence with SandStone or Voyage -> Bypassing the saving of a variable.
by sergio ruiz July 14, 2017

July 14, 2017

So, I tried using mongo voyage for persistence of my Models, and when trying to the SsStateMachine, Mongo Voyager had problems figuring out what to do with my state machine..Â So, it occurred to me.. the state machine really does nothing but guide the order through its journey. By the time the order is complete, the state machine is irrelevant.. and there is no chance that the state machine will ever be relevant..Â So, my question is..Â Is there any way to mark a variable (like statemachine) as âdo not persistâ?Â This would solve all my problems.. Thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Is there a 64bit minimal image for either 6.0 or 7.0?
by Tim Mackinnon July 14, 2017

July 14, 2017

Hi - I would like to try a minimal image on AWS lambda (so I need a 64 bit version). Is there a 64bit image for either 6.0 or 7.0 that is easy to download? I can see - http://get.pharo.org/60-minimal <http://get.pharo.org/60-minimal> but it doesnât say its 64 bit, so I assume its 32bit? Tim

Using SandstoneDB for persistance. Getting error.
by sergio ruiz July 13, 2017

July 13, 2017

Hi, all.. I am finally ready to work on the persistence end of my project. I am having a little bit of an issue, though.. I have very simple set of models: Customers Orders LineItems more.. The Customer has a variable called âordersâ which is just an OrderedCollection of Orders. The trick is, this is an SMS bot, so the order has a StateMachine (SsStateMachine) that, after it receives an SMS.. it processes it, and moves (or doesnât) along in state. the problem I have is, when I save the customer, I need to save the orders first (I got an error stating this). When I try to save the order, I get the following error: Â 'An ActiveRecord can not reference any sub instances of instruction stream. Â Make sure you are not saving blocks. â This looks like itâs happening at the point where it is trying to save the StateMachine.. Here is the full error.. Thanks!: Context(InstructionStream)>>sandstoneDeepCopyVisits: BlockClosure(Object)>>sandstoneDeepCopyVisits: SsState(Object)>>sandstoneDeepCopyVisits: SsStateMachine(Object)>>sandstoneDeepCopyVisits: Order(Object)>>sandstoneDeepCopyVisits: Order(SDActiveRecord)>>sandstoneDeepCopy SDFileStore>>storeObject: [ self validate.

2 questions around gitlab, gitfiletree, BaselineOf
by Sabine Manaa July 13, 2017

July 13, 2017

Hi, we have our own gitlab running now and I succeeded to move our code from sthub to it. I can push my new code into it from Pharo. All fine. I also created a Baseline (based on my former configurationOf). Loading the code from others (e.g. seaside) with this baseline is also fine. There are 2 Points where I am sure it could be better (it is worse) 1) For loading my own code, I currently have a bad solution It is in the postLoadBaseline and does this: | gitRepository | gitRepository := MCFileTreeRepository new directory: '/Applications/Pharo5.0-7.app/Contents/Resources/spf-gitlab/repository' asFileReference. {'RKA24-Model' . 'RKA24-System' . 'RKA24-Translator' . 'RKA24-View' . 'RKA24-Test' . 'RKA24-Report' . 'RKA24-Overwrites'} do: [ :each | Gofer it repository: gitRepository; package: each; load ]. I would like to load it within my baseline like this below but I dont know what to write in the fileTreeRepository method... baseline: spec <baseline> spec for: #common do: [ spec blessing: #baseline. spec repository: ##self fileTreeRepository##. "here I load all the the oher stuff" spec package: 'RKA24-Model'; package: 'RKA24-System'; package: 'RKA24-Translator'; package: 'RKA24-View'; package: 'RKA24-Test'; package: 'RKA24-Report'; package: 'RKA24-Overwrites' ] 2) Also, when I take a new Image, I have to do several steps load gitfiletree from catalog add/open my gitfiletree repository from Monticello load BaselineOfRKA24 manually with (BaselineOfRKA24 project map at: 'baseline') load I think this is not the best way, I would like to make it right. Can anyone give me some hints how to improve this two steps? I use Pharo 5 and I don't want to go to Pharo 6 right now. I develop on mac and production server is on windows.

Problems with PunQLite
by PBKResearch July 12, 2017

July 12, 2017

Hello I have decided to have another try with PunQLite, having failed to get it working before. For the record, I am using Windows 10 Home with all recent updates applied. I tried the following: 1. Download latest image of Moose 6.1 (Pharo 6.0 Latest update: #60507). 2. Search Catalog Browser for PunQLite, which is flagged as OK for Pharo 6.0, and select 'Install stable version'. 3. Check that the file unqlite.dll has been installed in the same folder as the image. 4. Run tests in PqDatabaseTests. 30 tests run, all red. 5. Try to run some tests manually. Enter 'PqDatabase openOnMemory' and 'doIt'. Result: 'Error: External module not found'. Looking at the Monticello Browser, I see that my image has ConfigurationOfPunQLite(TorstenBergmann.29) and PunQLite-Core(TorstenBergmann.28). This is the version chosen as stable by the Catalog Browser. Have I in fact got the right version? Do I have to do something with the .dll to make it visible to the .ffi call? Any suggestions gratefully received. Peter Kenny

Fwd: [CfP][Meta'17] Workshop on Meta-Programming Techniques and Reflection
by Guillermo Polito July 12, 2017

July 12, 2017

Hi all, sorry for multiple copies, ========================================================= Call for Papers: Metaâ17 ======================== Workshop on Meta-Programming Techniques and Reflection Co-located with SPLASH 2017 October 22, 2017, Vancouver, Canada Twitter @MetaAtSPLASH http://2017.splashcon.org/track/meta-2017 The heterogeneity of mobile computing, cloud applications, multicore architectures, and other systems leads to increasing complexity of software and requires new approaches to programming languages and software engineering tools. To manage the complexity, we require generic solutions that can be adapted to specific application domains or use cases, making metaprogramming an important topic of research once more. However, the challenges with metaprogramming are still manifold. They start with fundamental issues such as typing of reflective programs, continue with practical concerns such as performance and tooling, and reach into the empirical field to understand how metaprogramming is used and how it affects software maintainability. Thus, while industry accepted metaprogramming on a wide scale with Ruby, Scala, JavaScript and others, academia still needs to answer a wide range of questions to bring it to the same level of convenience, tooling, and programming styles to cope with the increasing complexity of software systems. This workshop aims to explore meta-level technologies that help tackling the heterogeneity, scalability and openness requirements of emerging computations platforms. ### Topics of Interest The workshop is a venue for all approaches that embrace metaprogramming: - from static to dynamic techniques - reflection, meta-level architectures, staging, open language runtimes applications to middleware, frameworks, and DSLs - optimization techniques to minimize runtime overhead - contract systems, or typing of reflective programs reflection and metaobject protocols to enable tooling - case studies and evaluation of such techniques, e.g., to build applications, language extensions, or tools - empirical evaluation of metaprogramming solutions - security in reflective systems and capability-based designs - meta-level architectures and reflective middleware for modern runtime platforms (e.g. IoT, cyber-physical systems, mobile/cloud/grid computing, etc) - surveys, conceptualization, and taxonomization of existing approaches In short, we invite contributions to the workshop on a wide range of topics related to design, implementation, and application of reflective APIs and meta-programming techniques, as well as empirical studies and typing for such systems and languages. ### Workshop Format and Submissions This workshop welcomes the presentation of new ideas and emerging problems as well as mature work as part of a mini-conference format. Furthermore, we plan interactive brainstorming and demonstration sessions between the formal presentations to enable an active exchange of ideas. The workshop papers will be published in the ACM DL, if not requested otherwise by the authors. Thus, they will be part of SPLASH workshop proceedings. Therefore, papers are to be submitted using the SIGPLAN acmart style: http://www.sigplan.org/Resources/Author/.
