Git working with release branches and build issues. (+ bonus auto script)

[porky code]

Hello. I am not an absolute newbie and have some experience with Chromium.
Here is discussed
(http://dev.chromium.org/developers/how-tos/get-the-code), Working with release branches section.
My task is to build chromium most stable release. I did it successfully with deprecated process of getting code from svn. But after moving to git I've faced with some issues. And some of them concerning your instructions. I've followed step by step official instruction and created script which automates official wiki actions. Here is github link https://github.com/porkycode/Chromium-Windows-Build
So what are the problems?



1) http://dev.chromium.org/developers/how-tos/get-the-code

"If it's taking a long time or looks like it's fetching a bunch of stuff from svn, something is probably wrong."

It not working not on git from windows command shell, nor on git from depot_tools.
It only works correctly if started from bash from this git distribution http://git-scm.com/download/win
Thats why in my project i need to create separate .sh script


2) http://dev.chromium.org/developers/how-tos/build-instructions-windows

No IDE is installed, however windbg is available in depot_tools\win_toolchain\vs2013_files\win8sdk\Debuggers\x86.

If no IDE installed, After switching to stable branch, and syncing with

gclient sync --jobs 16

the process is failed with error

After installation of  Visual Studio 2013 it works like a charm.


3)  Then I build Chromium. And receive:

ninja: Entering directory `out/Release'
ninja: error: 'C:\Program Files (x86)\Windows Kits\8.0\Redist\D3D\x86\d3dcompiler_46.dll', needed by 'd3dcompiler_46.dll', missing and no known rule to make it

So I need also to install Windows Software Development Kit (SDK) for Windows 8. Why it is not working from depot_tools folder?
After installation of windows 8 sdk error gone.


4) I trying to build again. The process started. Then I receive

[12632/15849] CXX obj\content\renderer\media\content_renderer.media_stream_dispatcher.obj
FAILED: ninja -t msvc -e environment.x86 -- "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64_x86\cl.exe" /nologo /showIncludes /FC @obj\content\renderer\media\content_renderer.media_stream_dependency_factory.obj.rsp /c ..\..\content\renderer\media\media_stream_dependency_factory.cc /Foobj\content\renderer\media\content_renderer.media_stream_dependency_factory.obj /Fdobj\content\content_renderer.cc.pdb

f:\chromium\sourcecode\src\third_party\libjingle\source\talk\app\webrtc\peerconnectioninterface.h(393) : see declaration of 'webrtc::PeerConnectionFactoryInterface::Options'
ninja: build stopped: subcommand failed.

So I need to edit src\third_party\libjingle\

source\talk\app\webrtc\peerconnectioninterface.h
And add  change

 public:
    Options() :
      disable_encryption(false),
      disable_sctp_data_channels(false) {
    }
    bool disable_encryption;
    bool disable_sctp_data_channels;
  };

to

 public:
    Options() :
      enable_aec_dump(false),
      disable_encryption(false),
      disable_sctp_data_channels(false) {
    }
    bool enable_aec_dump;
    bool disable_encryption;
    bool disable_sctp_data_channels;
  };

After this I can build successfully.

But i think this is a problem. According to src/DEPS file "talk" should be 5413

  "src/third_party/libjingle/source/talk":
    (Var("googlecode_url") % "webrtc") + "/branches/3.48/talk@5413",

but when I execute git log in src/third_party/libjingle/source/talk i see

commit fbb1efa61417540336cf52976d4ff4394bfa795b
Author: w...@webrtc.org <w...@webrtc.org@4adac7df-926f-26a2-2b94-8c16560cd09d>
Date:   Fri Dec 13 19:20:56 2013 +0000

    Update stable to r5287.

so "talk" should be 5413 but actually it is 5287

It should be mention that when I use deprecated svn process for getting source code it works correctly. Via svn I receive "talk" of version 5413

So the process works, but somebody, please, guide me to right way. Thanks!
