Shi, Steven 0e7e7a264c BaseTools: Improve the cache hit in the edk2 build cache
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1927

Current cache hash algorithm does not parse and generate
the makefile to get the accurate dependency files for a
module. It instead use the platform and package meta files
to get the module depenedency in a quick but over approximate
way. These meta files are monolithic and involve many redundant
dependency for the module, which cause the module build
cache miss easily.
This patch introduces one more cache checkpoint and a new
hash algorithm besides the current quick one. The new hash
algorithm leverages the module makefile to achieve more
accurate and precise dependency info for a module. When
the build cache miss with the first quick hash, the
Basetool will caculate new one after makefile is generated
and then check again.

This directory contains the next generation of EDK II build tools and template files.

Templates are located in the Conf directory, while the tools executables for

Microsoft Windows 32-bit Operating Systems are located in the Bin\Win32 directory, other

directory contains tools source.



1. Build step to generate the binary tools.



=== Windows/Visual Studio Notes ===



To build the BaseTools, you should run the standard vsvars32.bat script

from your preferred Visual Studio installation or you can run get_vsvars.bat

to use latest automatically detected version.



In addition to this, you should set the following environment variables:



 * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree

 * BASE_TOOLS_PATH - The directory where the BaseTools source is located.

   (It is the same directory where this README.txt is located.)



After this, you can run the toolsetup.bat file, which is in the same

directory as this file.  It should setup the remainder of the environment,

and build the tools if necessary.



Please also refer to the 'BuildNotes.txt' file for more information on

building under Windows.



=== Unix-like operating systems ===



To build on Unix-like operating systems, you only need to type 'make' in

the base directory of the project.



=== Ubuntu Notes ===



On Ubuntu, the following command should install all the necessary build

packages to build all the C BaseTools:



  sudo apt-get install build-essential uuid-dev



=== Python sqlite3 module ===

On Windows, the cx_freeze will not copy the sqlite3.dll to the frozen

binary directory (the same directory as build.exe and GenFds.exe).

Please copy it manually from <PythonHome>\DLLs.



The Python distributed with most recent Linux will have sqlite3 module

built in. If not, please install sqlit3 package separately.
