Performance of zero conf install since 6.1 seems very slow?

by Tim Mackinnon

Hi - has anyone else noticed that since 6.1 - using zero conf for installs is very very slow (it takes minutes to download pharo64.zip when using curl get.pharo.org/64/ | bash This is both on my local computer but also on the gitlab ci server? Is it possibly something isnât configured right? Tim

NeoJSON "conditional" parsing/mapping

by Esteban A. Maringolo

Hi Sven, all, I'm working on a JSON-RPC client, I started using LtJsonRpcClient, but since it's based on the "legacy" JSON package I decided to try to adapt it to use NeoJSON. So I created a NeoJSONRPCClient based on LtJson... because... why not. At its core JSON-RPC is a pretty simple protocol, every response is a JSON object with a 'result' attribute holding the returned object from the RPC call, an 'error' one (nil if no error happened), and a few other ones [1]. If I convert the response using the traditional `NeoJSONReader fromString: responseObject` all the object three is converted to a Dictionary, and what I want is to be able to: 1. Determine whether there was an error in the response 2. If there was no error, convert the 'result' field to my preferred class of object instead of a Dictionary. I plan to make my classes inherit from NeoJSONObject though. All the above to avoid the use of an intermediate set of nested dictionaries (which could be in the thousands). I understand I could subclass NeoJSONReader to perform that at the character stream level, but I wanted to ask first whether there is a pattern/configuration of dealing with something like this. Best regards! [1] http://www.jsonrpc.org/specification#response_object Esteban A. Maringolo

I will stop listening on my port for incoming HTTP connections. If unregister is true, unregister me from the list of managed instances. Does nothing when I am not running" self isRunning ifFalse: [ ^ self ]. unregister ifTrue: [ Error signal: 'stop: true was sent to running server!' ]. process terminate. process := nil. unregister ifTrue: [ self unregister ]. self closeDelegate. self logStopped As a result, different PharoDebug.log was generated (only in headless case, of course), which shows the server was indeed saved with both process and serverSocket being notNil.

Very strange. Somewhere between headless W10 shutdown and W10 ui startup something must be broken that made Zinc unregister the running and registered server. Herby

Re: [Pharo-users] Reef examples?

I tried to write something but I failed because this is too complex to have to understand first a frameworks and then write a real documentation. This costs me too much I cannot do it anymore.

Re: [Pharo-users] Looking for small boards and tiny computers which can run Pharo

by Bruce O'Neel

Hi, With a bit of work it probably fits on one of these: [https://onion.io/omega2/](https://onion.io/omega2/) If you feel on really wasting space this would work as well, though it would need some porting if you wanted to run it locally. [https://getchip.com/pages/pocketchip](https://getchip.com/pages/pocketchip) If you don't want the display and keyboard and want to run it remote this will work then, it's the CPU from the above. [https://getchip.com/pages/chip](https://getchip.com/pages/chip) If I get some free time I can poke at these and see how well Squeak etc runs. cheers bruce > Hi, > i am looking for: > - small hardware, boards/computers, "embeddable" devices, etc. that can run Pharo (except Raspberry pi that i already know) > - robots, flying drones or things alike with an open linux which can possibly run Pharo > Could somebody points me to documentation or web sites where such things can be found ? > Thanks, > Steven.

Re: [Pharo-users] [Pharo-dev] [ANN] Pharo 6.1 (summer) released!

Is just that it does not has so many changes :) this was a version we told it was going to be made available to update iceberg (as we use iceberg for develop P7, we need to have recurrent updates even in Pharo 6). And since there was important modifications, we needed to change the backend library. And since we changed the backend library, we needed to change the vm. Finally, since we changed the VM, we were unable to apply this update as a âhot-fixâ (what we do regularly, but version number does not change, just build number). So, Pharo 6.1 is exactly the same as before, but with: new iceberg, new vm, new backend library. cheers! Esteban ps: the other regressions, when fixed, can be applied as we usual apply backported hot-fixes. > > Le 25/07/2017 Ã 08:59, Hilaire a Ã©crit : >> Meaning these tow ones ? >> >> http://forum.world.st/Regression-with-PNGReaderWriter-in-P6-td4951796.html#… <http://forum.world.st/Regression-with-PNGReaderWriter-in-P6-td4951796.html#…> >> http://forum.world.st/WrapAthen-World-coordinate-td4951750.html#a4951966 <http://forum.world.st/WrapAthen-World-coordinate-td4951750.html#a4951966> > -- > Dr. Geo > http://drgeo.eu <http://drgeo.eu/>
