Re: [Pharo-dev] Pharo for the Raspberry Pi

Ok. This means I may suggest someone to lend some manpower to look into that. I'll ask. Could a stackVM and an ARM NB be a reasonable, short term target? I saw someone saying he would start on ASMJit for ARM a while back.

Re: [Pharo-dev] HTTPProgress Content-Length v.

I've pulled out some code to Workspace script into [2] with the resulting Transcript result shown in [3]. I'm guessing this is due to the _"Transfer-Encoding: chunked"_ header clashing with the "Content-Length" header [1]. By putting a 'self halt' in ZnStatusLine>>readFrom: and executing several "Transcript crShow: (ZnLineReader on: stream) nextLine" the real headers were found as shown in [4], from which it seems the Content-Length is faked-up after the download finishes, and no use for a progress bar. >>> >>> >> >> Completely correct!

This is an unusual request, I've never needed it, I guess you could do something like | client | client := ZnClient new. client url: 'http://zn.stfx.eu/zn/small.html'. client request requestLine version: 'HTTP/1.0'. client get. client > Maybe a downside of forcing HTTP/1.0 would requiring the server to not be a VirtualHost (??). Does anyone know how the configuration of the servers used by Pharo Launcher relate to this? But yes, you will break lots of stuff, and for what ? I mean, is it so bad that one of the downloads has no real progress bar ? How long can an 80Kb download take ? There should still be a dialog that says downloading with a moving byte count, the graphic should be an animated in definitive progress bar. > -ben > > [5] http://webmasters.stackexchange.com/questions/38738/how-to-avoid-chunked-tr… > [6] http://www.jargonsoft.com/support/knowledgebase.php?article=12 > >> >>> cheers -ben >>> >>> >>> [1] >>> http://stackoverflow.com/questions/2419281/content-length-header-versus-chu… >>> >>> >>> "[2]start------------------Workspace-script----------" >>> workBlock := >>> [ ZnClient new >>> signalProgress: true ; >>> url: ' >>> http://files.pharo.org/image/30/ >>> ' ; >>> enforceHttpSuccess: true ; >>> beOneShot ; >>> accept: 'text/html;charset=utf-8' ; >>> enforceAcceptContentType: true ; >>> logToTranscript ; >>> get >>> ]. >>> >>> UIManager default informUserDuring: >>> [ :bar| >>> [ workBlock value] on: HTTPProgress do: >>> [ : progress | >>> Transcript crShow: '# ' , progress printString , >>> ' total=' , progress total asString , >>> ' amount=' , progress amount asString. >>> bar label: progress printString. progress isEmpty ifFalse: [ bar current: progress percentage ]. >>> progress resume. >>> ]. >>> ]. >>> "[2]end------------------Workspace-script----------" >>> >>> >>> "[3]start--------------Transcript------" >>> # HTTPProgress: Connecting to files.pharo.org total=nil amount=nil >>> 2013-10-02 00:43:36 428852 I Wrote a ZnRequest(GET /image/30/) >>> 2013-10-02 00:43:36 428852 D Sent headers >>> Accept: text/html;charset=utf-8 >>> User-Agent: Zinc HTTP Components 1.0 >>> Connection: close >>> Host: files.pharo.org >>> # HTTPProgress: Writing request total=nil amount=nil >>> # HTTPProgress: Reading response total=nil amount=nil >>> ZnUtils>>signalProgress: 16384 total: nil >>> # HTTPProgress: Tranferred 16.38k bytes ... total=nil amount=nil >>> ZnUtils>>signalProgress: 32768 total: nil >>> # HTTPProgress: Tranferred 32.77k bytes ... total=nil amount=nil >>> ZnUtils>>signalProgress: 49152 total: nil >>> # HTTPProgress: Tranferred 49.15k bytes ... total=nil amount=nil >>> ZnUtils>>signalProgress: 65536 total: nil >>> # HTTPProgress: Tranferred 65.54k bytes ... total=nil amount=nil >>> ZnUtils>>signalProgress: 81920 total: nil >>> # HTTPProgress: Tranferred 81.92k bytes ... total=nil amount=nil >>> ZnUtils>>signalProgress: 85434 total: nil >>> # HTTPProgress: Tranferred 85.43k bytes ... total=nil amount=nil >>> 2013-10-02 00:43:38 428852 I Read a ZnResponse(200 OK text/html;h5ai=0.22.1;charset=UTF-8 85444B) >>> 2013-10-02 00:43:38 428852 D Received headers >>> Date: Tue, 01 Oct 2013 16:43:34 GMT >>> Transfer-Encoding: chunked >>> Content-Length: 85444 >>> Vary: Accept-Encoding >>> Server: Apache >>> Connection: close >>> Content-Type: text/html;h5ai=0.22.1;charset=UTF-8 >>> 2013-10-02 00:43:38 428852 T GET /image/30/ 200 85444B 1874ms >>> "[3]end--------------Transcript------" >>> >>> "[4]start----------ZnStatusLine>>readReal-Headers--------" >>> HTTP/1.1 200 OK >>> Date: Tue, 01 Oct 2013 17:23:55 GMT >>> Server: Apache >>> Vary: Accept-Encoding >>> Connection: close >>> Transfer-Encoding: chunked >>> Content-Type: text/html;h5ai=0.22.1;charset=UTF-8 >>> "[4]end-----------Real-Headers--------" >>> >>> >>> >>> >> >> >> >> >> >

I don't think it has to do with Cog, but rather with a few silly primitives related to files and time, I am just not sure which ones.
