Re: [webkit-dev] Error Handling in webkit

[Nitin Walke]

Hi Jenson,

  I didn't get curl header file in webkit.Can u explain in brief how can we
convert curl error to http error? Where we have to make code changes in
webkit so that we can get proper message on browser?Is there a standerd way
to do this?I am new in webkit.
Thanks in advance.

Regards,
Nitin

Re: [webkit-dev] Xcopy: Cannot perform a cyclic copy

[Paul Pedriana]

I believe that output is not indicating a build failure and that it can
be ignored. 

The WebKit Windows build produces a number of "red herring" outputs
(output that looks like an error but isn't), and the traffic on this
mailing list would likely be reduced if this was documented. Ditto for
the other undocumented gotchas of the Windows build. Perhaps we should
form a little committee to address this.





  Hi,
  I am working on a university project to build a webbrowser using
WebKit framework for my class. I followed all the instruction on the webkit.org page,
however, i get an error when i try to build webkit. 
  The error message:
   
  "Microsoft (R) Visual Studio Version
8.0.50727.762.

1>Cannot perform a cyclic copy
1>0 File(s) copied"
  This is the first error that occurs. I know why Xcopy fails, but i
don't know what i have to change to make it work. If anyone has an idea
or experience with this error, please let me know. It will be very
appreciated.
  I am using Windows XP, Visual Studio 2005.

Re: [webkit-dev] want to port JIT to MIPS

[x yz]

Thanks a lot otherwise I have misunderstanding. Yes I'll do wrec first. I just 
want to clean up possible blocking issues.

I see wrec uses regparm(3) and jit always use fastcall for X86?
In JIT.cpp ctiTrampoline put CallFrame in edi, but how about other arguments - 
where are they be fetched/poped from stack? 

when deal with caller/callee saved regs, gcc MIPS just preserves them when 
necesasary. The problem is after JIT used gcc may not have enough knowledge on 
"necessary", do we have a way to force gcc always preserve 
them? 

how to identify a patch (patchimm/patchptr/patchaddr) relates to a data field 
in an instruction or relates to an element in a data array? In Mips the former 
means the 32bit needs to be separated into two 16bits and patched into two 
instructions. But if a 32bit is a pointer in a pointer array, we can save it 
directly.

Re: [webkit-dev] Webkit Building errors in VC++2005

[Frank Thomsen]

Hi Mital

I read that wiki page, as well as followed the guidelines beginning with 
http://webkit.org/building/tools.html to the lette. I had two colleagues do the 
same - same result. It was when I found the link included in the last mail that 
I finally got a breakthrough. There is just too much information missing in the 
"official" guidelines, I'm sorry to say. I would advice someone to rewrite it :)

Frank

hi,
It seems that u have not followed the instructions for building webkit in 
Windows.
refer http://trac.webkit.org/wiki/BuildingOnWindows

also check weather u have all the required packages for cygwin are installed 
properly. verify wiht the below list.

Hi



I ran into the exact same problem (amongst a lot of others); The guideline on 
webkit.org it far from helpful. So I dug through the net and 
found the following two pages. Hopefully they can be of some assistance. Pay 
close(!) attention to the first - a lot of good hints!
