[Kde-imaging] flickr / picasaweb?

[Vardhman Jain]

Hey,
     I was trying to figure out the problem behind flickr' upload failing on
KDE4 port for quite a lot of time. I could figure out the root cause but the
solution probably needs some suggestions from someone with more QT
knowledge.

The problem is in the POST request that is being sent to the flickr server
for photo upload. With some ethereal log analysis I cud see that the server
is responding saying the package size is too large. This is happening
because of the HTTP post request data not being properly packed up.

The code for packing uses QTextStream which probably changed its behaviour
from QT3 to 4 or such is my first guess. I tried running this test code to
undestand if QTextStream should be used to append some data in to a
QByteArray (Not sure why we need to do this instead of resizing and updating
the QByteArray, but that aside)

QByteArray qba("test");
QTextStream qts(qba, QIODevice::Append);
qts << "ABCD";
kdDebug() << qba <<"#"<< qts.string() << endl;
qts << endl;
kdDebug << qba << "#" << qts.string() << endl;

I get
test#
test#

Is this expected behaviour or am I doing something wrong. Also is TextStream
supposed to resize bytearray automatically in this case ? (The code related
to these lines is in graphics/kipi-plugins/flickrexport/mpform.cpp)

regards
Vardhman
