ZnClient send big data + progress
by roberto.minelli＠usi.ch June 6, 2014

June 6, 2014

Hi guys, I have a problem with Zinc, I need to send a huge amount of data (bytes) that translates to ~50Mb. When I do something like: ZnEasy post: 'http://localhost:15432' data: (ZnEntity bytes: aHugeByteArray.] I encounter a âConnectionTimedOut: Data send timed out.â, I attach the stack trace: ZdcSocketStream(ZdcSimpleSocketStream)>>flushBytes:startingAt:count: ZdcSocketStream>>next:putAll:startingAt: ZnBivalentWriteStream>>next:putAll:startingAt: ZnUtils class>>nextPutAll:on: ZnByteArrayEntity>>writeOn: ZnEntityWriter>>writeEntity: ZnRequest(ZnMessage)>>writeOn: ZnRequest>>writeOn: ZnClient>>executeRequestResponse ZnClient>>getConnectionAndExecute in Block: [ self executeRequestResponse ] BlockClosure>>ensure: ZnClient>>getConnectionAndExecute ZnClient>>executeWithRedirectsRemaining: ZnClient>>executeWithRetriesRemaining: in Block: [ self executeWithRedirectsRemaining: self maxNumb...etc... BlockClosure>>on:do: ZnClient>>executeWithRetriesRemaining: ZnClient>>executeWithTimeout in Block: [ self executeWithRetriesRemaining: self numberOfR...etc... BlockClosure>>on:do: ZnClient>>executeWithTimeout in Block: [ ... ZnClient>>withTimeoutDo: in Block: [ ^ block value ] ZnConnectionTimeout(DynamicVariable)>>value:during: in Block: [ ... BlockClosure>>ensure: ZnConnectionTimeout(DynamicVariable)>>value:during: ZnConnectionTimeout class(DynamicVariable class)>>value:during: ZnClient>>withTimeoutDo: ZnClient>>executeWithTimeout ZnClient>>execute in Block: [ result := self executeWithTimeout ] ZnClient>>withProgressDo: in Block: [ ^ block value ] ZnSignalProgress(DynamicVariable)>>value:during: in Block: [ ... BlockClosure>>ensure: I tried to: - Augment the client timeout to a huge value (10 mins) but it has no effect: The data send still goes into timeout, after 10-15 sec - I replaced the ZnEntity with a ZnMultiPartFormDataEntity, still no luck I am wondering what else can I do. Moreover, I discovered there is a #signalProgress: message to signal process. The following examples do not work, any hint? ################################################################################ Example 1, from the book @ http://zn.stfx.eu/zn/zinc-http-components-paper.html: UIManager default informUserDuring: [ :bar | [ ^ ZnClient new signalProgress: true; get: 'http://zn.stfx.eu/echo?delay=2' ] on: HTTPProgress do: [ :progress | bar value: progress printString. progress resume ] ] ################################################################################ Example 2, from ZnClientTests>>#testProgress works, but not when issuing a POST request [ :bar | bar title: 'Downloading Sources...'. [ ZnClient new url: 'http://files.pharo.org/sources/PharoV30.sources'; signalProgress: true; downloadTo: FileLocator temp ] on: HTTPProgress do: [ :progress | progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ] ] asJob run. â¦works but only when using #downloadTo: if you do a #post:contents: or a #get: as in the example with #get: 'http://zn.stfx.eu/echo?delay=10' no process is shown. Any hint? Thanks in advance, Roberto

Is there an Amber-Pharo one click built with CI to allow development with both (amber for client, pharo on server). If not is it planned to provide one? Thx T.

TextMorph on Athens
by Hilaire Fernandes June 4, 2014

June 4, 2014

Hi, DrGeo needs to know what is the status of TextMorph on Athens. I have been through most of the broken parts of DrGeo@Pharo3 (really a lot!), and this one is the last one AFAIK. Depending on, I may write a temporary hack to bypass textmorph, but may be it is not necessary and DrGeo can wait a bit, but I need to know. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-dev] Brainstorming Pharo4

If we can integrate libtorrent as well, we should be able to use our dvcs as it is supposed to be used: peer-to-peer. Github is a fine place to store backups :) I assume the embeddable vm work includes resurrecting coral? We can create a ConfigurationOfGlamour that avoids loading the whole of Moose ;) Stephan

Some PharoVM work news
by Esteban Lorenzano June 4, 2014

June 4, 2014

Hi, Iâve been working on re-aligning our sources to latest Eliot sources. This is a step previous to compile a spur vm for Pharo. So farâ¦ it was a lot of work but I have a working version (in mac, not yet tested in others)â¦ but I forget to port Igorâs finalization improvements (I forgot it was there and I passed over it when merging), now I have to put it back inâ¦ Overallâ¦ I have the impression latest Eliot versions are 5-10% faster than our current ones, but Iâm not sure (it could be just a good day for my machine), so we will need to wait until release. This is a necessary step: our codebase is diverging more and more from Eliotâs without any good reason, just a direct application of entropy laws, and we need to realign if we want to continue working together (and we certainly want :D). With luck, this work will be finished for the end of the week. cheers, Esteban
