[Solved] Delay with accessibility of downloaded file?

[netsoul]

Hi all,
I've faced with a some problem during downloading files. Really, a downloaded file isn't accessible for reading at the moment when KL returns klError=0&klEnd=1. Symbian returns 'Unable to find file c:/...'. But it can be read in a few moments later.

This's not a blocker but this adds a headache to OOP developers. Can you please specify the following: klEnd returns on the moment of download complete or on the moment of saving complete?

Thanks,
Alex

Hi,

actually klStatus is intended to be used to catch "download complete" event.
klCommand=status, then poll for variable klProgress eq 100,

ok, I'll try it but what does it mean:
"klEnd value indicates that conversation is finalized and all data is received"?

I guess, the status is useful to show the download progress but not to handle an event of ending? The reasonable question: is klEnd the same of klProgress==100? And how much time requires to write the received data after the event klProgress==100?

Thanks,
Alex

"klEnd value indicates that conversation is finalized and all data is received"?

Actually this refers to the message incoming from KuneriLite server. For instance if you have 3 variables in KL response, klEnd indicates all 3 values are received by FL. klEnd is definitely different than other arguments. It's only ensuring FL got whole response from KL server, not related to any plugin specifically.

I remember facing such problem with download complete event. We will study this and try to correct the issue. Right behavior should be receiving klStatus=complete only when file is ready to be read, and developers should be able to trust on that.

That's how I detect completed download in KISS60;

Code:

if(/:klStatus eq "complete") { // Is download complete?
    gotoAndPlay("PROCESS_COMPLETE");
} else {
    XXXX
}

Thanks for raising the issue Alex!

Yes, thanks Alex,
wiki wasn't up-to-date, now it is corrected.

We'll investigate this problem:
The data is being written into file during download, but file seem to be remain unlocked sometimes even klStatus=complete.

cheers,

Thanks you too. The situation is clearer to me now.

Hi again,

The process of downloading works more stably in 0.95. One more point is to improve. If download is unsuccessful, a zero-length file stays in the phone. It look like a successful download of empty file for the following command Exist or the following application session.

Hi Alex, I am sure Jukka will check this out. I personally delete file(s) manually from Flash Lite side, if a download is not successful. This especially is a good idea, if you are downloading more than one file consequently.

Nice to hear that Download is working better now.

BTW, we forgot to document one more thing, I think it will make downloading much better for you. It's loadVariables command for Ul/Dl plugin.

Code:

loadVariables("http://127.0.0.1:1001/Basic/uldl?klCommand=loadVariables&klUrl=XXXX, "", "POST");

This will eliminate 2 times AP, if you have to connect to internet before downloading.

Am sure Jukka will update this soon.
