Instead of running N pair-wise diff-trees when inspecting a N-parent merge, find the set of paths that were touched by walking N+1 trees in parallel. These set of paths can then be turned into N pair-wise diff-tree results to be processed through rename detections and such. And N=2 case nicely degenerates to the usual 2-way diff-tree, which is very nice. * ks/tree-diff-nway: mingw: activate alloca combine-diff: speed it up, by using multiparent diff tree-walker directly tree-diff: rework diff_tree() to generate diffs for multiparent cases as well Portable alloca for Git tree-diff: reuse base str(buf) memory on sub-tree recursion tree-diff: no need to call "full" diff_tree_sha1 from show_path() tree-diff: rework diff_tree interface to be sha1 based tree-diff: diff_tree() should now be static tree-diff: remove special-case diff-emitting code for empty-tree cases tree-diff: simplify tree_entry_pathcmp tree-diff: show_path prototype is not needed anymore tree-diff: rename compare_tree_entry -> tree_entry_pathcmp tree-diff: move all action-taking code out of compare_tree_entry() tree-diff: don't assume compare_tree_entry() returns -1,0,1 tree-diff: consolidate code for emitting diffs and recursion in one place tree-diff: show_tree() is not needed tree-diff: no need to pass match to skip_uninteresting() tree-diff: no need to manually verify that there is no mode change for a path combine-diff: move changed-paths scanning logic into its own function combine-diff: move show_log_first logic/action out of paths scanning |

The Steps of Build Git with VS2008
1. You need the build environment, which contains the Git dependencies
to be able to compile, link and run Git with MSVC.
You can either use the binary repository:
WWW: http://repo.or.cz/w/msvcgit.git
Git: git clone git://repo.or.cz/msvcgit.git
Zip: http://repo.or.cz/w/msvcgit.git?a=snapshot;h=master;sf=zip
and call the setup_32bit_env.cmd batch script before compiling Git,
(see repo/package README for details), or the source repository:
WWW: http://repo.or.cz/w/gitbuild.git
Git: git clone git://repo.or.cz/gitbuild.git
Zip: (None, as it's a project with submodules)
and build the support libs as instructed in that repo/package.
2. Ensure you have the msysgit environment in your path, so you have
GNU Make, bash and perl available.
WWW: http://repo.or.cz/w/msysgit.git
Git: git clone git://repo.or.cz/msysgit.git
Zip: http://repo.or.cz/w/msysgit.git?a=snapshot;h=master;sf=zip
This environment is also needed when you use the resulting
executables, since Git might need to run scripts which are part of
the git operations.
3. Inside Git's directory run the command:
make common-cmds.h
to generate the common-cmds.h file needed to compile git.
4. Then either build Git with the GNU Make Makefile in the Git projects
root
make MSVC=1
or generate Visual Studio solution/projects (.sln/.vcproj) with the
command
perl contrib/buildsystems/generate -g Vcproj
and open and build the solution with the IDE
devenv git.sln /useenv
or build with the IDE build engine directly from the command line
devenv git.sln /useenv /build "Release|Win32"
The /useenv option is required, so Visual Studio picks up the
environment variables for the support libraries required to build
Git, which you set up in step 1.
Done!
