yes please remove it. I was the one who was probably most interested
in it in past.

...speaking of which...

It's probably about time someone sends a patch to remove cef, it has
been a while since anyone cared for it.

Heh, you're lucky with "oe-core maintenance".

My "bitbake world" builds have few components like this, webkitgtk (used to
have webkit1, webkit2 and webkit2-efl as separate builds), 2 chromiums (x11
and wayland), cef (luckily broken and whitelisted for a while), firefox,
qtwebengine, qtwebkit. Each taking usually even more time than "simplest"
webkitgtk2.

Building world with just oe-core takes just hour(s), add few layers like me
and it's day(s).

So progress bars are nice, but I still hate looking at them.

webkit is already using gold by default, except for some architectures 
(aarch64, mips) where it used to fail - maybe it is not necessary anymore.

In order of decreasing tongue in cheekiness.

1. Rewrite webkit in something that is not C++ - by far the most awful 
language when it comes to compile times.


2. Use icecc.bbclass to 'borrow' computing power from colleagues 
(untested, unproven).


3. Invest into a serious CPU. I have 22 cores here, and it is not a 
luxury, but an absolute necessity to get anything done as far as oe-core 
maintenance goes. Webkit's do_compile takes about half an hour - I can 
almost see that progress bar move :)

this is not easy and from my side what I have done some profiling based
on the buildstats to figure out the top consumers recipes/tasks. As you
mentioned, webkitgtk is the winner, at least for utimes!

[yocto] webkitgtk2 progress bar

2017-05-24 Thread Gary Thomas 

I see that the latest master update has brought a progress bar
for this (and presumably other 'cmake' based packages) - very nice :-)

Now [tongue-in-cheek], can someone do something about the horrendous
build times for such packages (webkitgtk2 can take up to 3 hours on
my [no so slow] build host!)?
