Description Elias Probst 2011-12-23 08:21:05 UTC

Version: unspecified (using Devel)
OS: Linux

When pasting text, longer than 513 characters (URL-encoded 741) using the default engine 'kde' (paste.kde.org), the upload will fail.

Reproducible: Always

Steps to Reproduce:
1. Copy the following text (it ends in a whitespace)
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet
This is

2. Paste it using the 'kde' engine to the pastebin applet
3. It works
4. Add a single character to the previous text, so copy the following text:
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet
This is a text which is just there to test a bug in the pastebin applet

4. Paste it using the 'kde' engine to the pastebin applet

Actual Results:
3. works
4. doesn't work

Expected Results:
3. works
4. works

Although the error is caused by the application running on paste.kde.org, I believe this could be solved in the shareprovider engine. It currently uses GET as submit method, while the form on paste.kde.org uses POST to submit the data.

Using:
KDE 4.7.90 (4.8.0 beta2)
Qt 4.7.4

Hello,

Thanks for reporting! The 'GET' shouldn't be a problem as it's supported by the API: http://paste.kde.org/doc/api/

Other backends work well with the same text. Interesting. I'll investigate but it would be good if you could take a look too as I'm a little bit out of time.

Thanks!

This is a good junior job for someone looking into starting kde development :)

Comment 3 Dario Cambié 2012-08-04 10:31:59 UTC

The problem is indeed the GET method (probably the URL becomes too long?) since changing

function method() {
    return "GET";
}

to

function method() {
    return "POST";
}


in kde/kde-workspace/plasma/generic/dataengines/share/backends/kde/contents/code/main.js make the plasmoid works with long text (cfr. http://paste.kde.org/528422/)

Fix Bug 289647 - Default text engine 'kde' fails when pasting text longer than 513/741 characters

Use "post" instead of "get" method for kde paste bin.
HTTP get method only support 1024 url length.
FIXED-IN: 4.11.0
