[work-around] Using proxy on GTK MiniBrowser

Caveat : This code is not contributable!! Just for local test! :-)

Just export http_proxy on your machine.(bashrc, profile, environment .. whatever)

[WebKit] Render code flow when you set src on img tag.

 Aside from setting value via idl interface, rendering has its own flow.

As you can see below, from the loader, RenderObject has callback for its resource change. Then, it will compare the width and height if it really has been changed and trigger setNeedsLayout with relevant value.

How to download webkitgtk-test-fonts archive when you are behind firewall.

As WebKitten, it is unfortunate that I am working behind firewall.
I don't think this is acceptable for web developers.
Anyway, I have no power to get rid of it from my surroundings :-), alternatively here I leave how we can download files, specifically those repositories are not certified.

Easy. Add '--no-check-certificate' option!

wget --no-check-certificate https://github.com/downloads/mrobinson/webkitgtk-test-fonts/webkitgtk-test-fonts-0.0.3.tar.gz

Have fun!

When got os error no 38, function not implemented, on emulation environment

I had got an os error no 38, function not implemented, on emulation environment. This was about shared memory. For this, I made a simple test program.

[test.cpp]

#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <stdlib.h>
#include <sys/mman.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <unistd.h>

extern int errno;

int main()
{
    int fd;

    fd = shm_open("/Test/123456789", O_CREAT | O_CLOEXEC | O_RDWR, S_IRUSR | S_IWUSR);

    if (fd == -1)
        fprintf(stderr, "errno[%d] \n", errno);

    return 0;
}

$ gcc test.cpp -lrt

$ ./a.out

errno[38] // usually return 2, path problem

I first thought it is absurd because shm_open function is really basic function provided by glibc. Later, I got realized this was from emulation environment specifically mount problem.

There was '/dev/shm' linked to '/run/...' but actually '/run/...' path wasn't existed. So I mounted '/run' to virtual path on emulator like '/var/tmp/blahblah/run' and solved the problem. You can do like this 'sudo mount -o bind /run /var/tmp/blahblah/run'.

Hope this might help.

Setting some environment variables

We can avoid unnecessary conflict between two glib 2.0 (new one vs default) by setting env variables in bashrc.

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

export LD_INCLUDE_PATH=/usr/local/include:$LD_INCLUDE_PATH

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

Using latest libsoup for WebKit EFL

WebKit EFL requires newer version of libsoup 2.4 than default in Ubuntu 11.10

Moreover, libsoup has strong dependency on glib 2.0 and more.

So I am writing here about my latest successful assembling.

  • ./configure --prefix=/usr/local
  • make; sudo make install

Grails 2.0 proxy configuration on Windows 7

Like me, behind firewall, some Grails engineers need to set proxy configuration on Windows 7.

This cool link will help you.
