git/compat/vcbuild, branch v2.2.0

Merge branch 'ks/tree-diff-nway'

2014-06-03T19:06:40Z

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

mingw: activate alloca

2014-04-09T17:08:35Z

Both MSVC and MINGW have alloca(3) definitions in malloc.h, so by moving win32-compat alloca.h from compat/vcbuild/include/ to compat/win32/ , which is included by both MSVC and MINGW CFLAGS, we can make alloca() work on both those Windows environments. In MINGW, malloc.h has explicit check for GNUC and if it is so, defines alloca to __builtin_alloca, so it looks like we don't need to add any code to here-shipped alloca.h to get optimum performance. Compile-tested on Windows in MSysGit. Signed-off-by: Kirill Smelkov Acked-by: Erik Faye-Lund Signed-off-by: Junio C Hamano

MSVC: allow linking with the cURL library

2014-03-27T19:05:14Z

Teach the clink.pl script that -lcurl is a request to link with the cURL library, and drop NO_CURL from config.mak.uname for the MSVC platform. Signed-off-by: Marat Radchenko Signed-off-by: Junio C Hamano

mark Windows build scripts executable

2013-11-25T23:01:22Z

On Windows the convention is to rely on filename extensions to decide whether a file is executable so Windows users are probably not relying on the executable bit of these scripts, but on other platforms it can be useful documentation. Signed-off-by: Jonathan Nieder Signed-off-by: Junio C Hamano

msvc: Fix build by adding missing symbol defines

2013-02-25T20:40:03Z

In particular, remote-testsvn.c fails to compile with two undeclared identifier errors relating to the 'UINT32_MAX' and 'STDIN_FILENO' symbols. In order to fix the compilation errors, we add appropriate definitions for the UINT32_MAX and STDIN_FILENO constants to an msvc compat header file.

msvc: Fix compilation errors caused by poll.h emulation

2013-02-25T20:39:56Z

Commit 0f77dea9 ("mingw: move poll out of sys-folder", 24-10-2011), along with other commits in the 'ef/mingw-upload-archive' branch (see commit 7406aa20), effectively reintroduced the same problem addressed by commit 56fb3ddc ("msvc: Fix compilation errors in compat/win32/sys/poll.c", 04-12-2010). In order to fix the compilation errors, we use the same solution adopted in that earlier commit. In particular, we set _WIN32_WINNT to 0x0502 (which would target Windows Server 2003) prior to including the winsock2.h header file. Also, we delete the compat/vcbuild/include/sys/poll.h header file, since it is now redundant and it's presence may cause some confusion.

MSVC: Remove unneeded header stubs

2011-11-01T03:06:06Z

These headers are no longer needed since they are no longer unnecessarily included in git-compat-util.h. Signed-off-by: Vincent van Ravesteijn Acked-by: Erik Faye-Lund Signed-off-by: Junio C Hamano

msvc: Fix build by adding missing INTMAX_MAX define

2010-12-10T00:00:30Z

Commit c03c831 (do not depend on signed integer overflow, 05-10-2010) provokes an msvc build failure. The cause of the failure is a missing definition of the INTMAX_MAX constant, used in the new maximum_signed_value_of_type(a) macro, which would normally be defined in the C99 header file. In order the fix the compilation error, we add an appropriate definition of the INTMAX_MAX constant, along with INTMAX_MIN and UINTMAX_MAX, to an msvc compat header file.

win32: use our own dirent.h

2010-11-24T00:06:50Z

The mingw-runtime implemenation of opendir, readdir and closedir sets errno to 0 on success, something that POSIX explicitly forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be read due to EMFILE") introduce a dependency on this behaviour, leading to a broken "git clone" on Windows. compat/mingw.c contains an implementation of readdir, and compat/msvc.c contains implementations of opendir and closedir. Move these to compat/win32/dirent.[ch], and change to our own DIR structure at the same time. This provides a generic Win32-implementation of opendir, readdir and closedir which works on both MinGW and MSVC and does not reset errno, and as a result git clone is working again on Windows.
