[Solved] Max size for WRITE

[netsoul]

Hi again,

Are there any limitation of maximal size of string in the command 'write' for File plugin? It looks like it works with maximal string length about 700 bytes on my N95. The larger strings invoke a crash of application.

I guess, this's a limitation of GET request.
... is it possible, to define a variable's name in the request, and server will read the variable value from the clip directly, to write to a file?

Hi,
I think string is klData argument, right?
There are no limits set for it.

Lets me test also this..

I guess, this's a limitation of GET request.

I also would think so.

... is it possible, to define a variable's name in the request, and server will read the variable value from the clip directly, to write to a file?

I think this wouldn't be possible. Read/write is only one direction. If there is a really big chunk of data, I would separate that into pieces and append to a file.

cheers,

Unfortunately, not any data can be splited in Flash. And how much time will be required to write 40Kb and more data by 500 byte pieces?

[KL Admin]

This must be something else, due I just wrote 2,5K long string in klData into file. Although player was 1.1 and phone E61.

[C00L]

Hmm, might there be restricted characters in the data you are trying to write? For instance, instead of '&' you should use %26. Jukka, is there any list for such data on Wiki?

Ugur.-

[netsoul]

I use 'escape()' function to encode data before... I'm creating a separate test to investigate it too on my phone.

[KL Admin]

Hi,
that is not necessary. KL can handle even '&' occurs in between the variables. That has been discussed many times;)

Back to the problem; I think loadVariables cannot handle 40Kb of data at a time, and you should have some kind of sending buffer mechanism in FL side.

[netsoul]

I've just tested klFile plugin on my N95 (FL 2.0 preinstalled) in separate application with a 'clear' text - it allows save 614 bytes of the text with url-encoding. So, to write 40Kb by 600 byte portions, it needs 67 iterations. It isn't a perfect solution, IMHO.

[C00L]

Yes, that's not really reasonable. We did not intentionally limit this, I would guess this would be a FL side problem. We should check this out to be sure though. But in any case, I don't think that loadVariables could handle 60Kb of data at one time.

[netsoul]

I didn't tried to use loadVariables for loading a great data into FL 2.1, except of loading via socket with help of native BREW extention.

May be any way exists to use POST method to transmit a data to KL server?

[KL Admin]

Hi,
even I define POST method in loadVariables, and when I check server side logs, I see that FL uses still sometimes GET method.

It would be great to know the logic it follows..

EDIT: Ok, now when I recalled more about this, and the fact that we don't support sending variables in separate header (in POST method), due that might be problematic in some cases.

We'll have some feasibility study about that, if theres any outcome to enable it.

EDIT: Wiki is updated for the POST method usage.

[KL Admin]

We have new information concerning this.
If you try to add very long strings to loadVariables,
Flash will crash. In such cases we'd suggest to write data in parts or just embed all data in loadVariables.

For instance this will cause Flash to crash if "test" variable is about 1000 bytes:
loadVariables("http://127.0.0.1:1001/Basic/file?klCommand=write&klUrlDecodeOff=1&klPath=test2.txt&klData="+test, "");

but as embedded call, it works when you add about 1000 bytes after klData
loadVariables("http://127.0.0.1:1001/Basic/file?klCommand=write&klUrlDecodeOff=1&klPath=test2.txt&klData=
ABCD1234567...

looks like Flash bug?

[netsoul]

Unfortunately, your solution does not work on my N95-1:
- Adobe Flash CS3 does not crash in simulation
- real device application crashes in the similar way both with included and external variables for loadVariables method.
