Johannes Schindelin	e4347c9434	msvc: handle DEVELOPER=1 We frequently build Git using the `DEVELOPER=1` make setting as a shortcut to enable all kinds of more stringent compiler warnings. Those compiler warnings are relatively specific to GCC, though, so let's try our best to translate them to the equivalent options to pass to MS Visual C++'s `cl.exe`.

Johannes Schindelin	ed712ef8d5	msvc: ignore some libraries when linking To build with MSVC, we "translate" GCC options to MSVC options, and part of those options refer to the libraries to link into the final executable. Currently, this part looks somewhat like this on Windows: -lcurl -lnghttp2 -lidn2 -lssl -lcrypto -lssl -lcrypto -lgdi32 -lcrypt32 -lwldap32 -lz -lws2_32 -lexpat Some of those are direct dependencies (such as curl and ssl) and others are indirect (nghttp2 and idn2, for example, are dependencies of curl, but need to be linked in for reasons). We already handle the direct dependencies, e.g. `-liconv` is already handled as adding `libiconv.lib` to the list of libraries to link against. Let's just ignore the remaining `-l` options so that MSVC does not have to warn us that it ignored e.g. the `/lnghttp2` option. We do that by extending the clause that already "eats" the `-R` options to also eat the `-l*` options.

Johannes Schindelin	976aaedca0	msvc: add a Makefile target to pre-generate the Visual Studio solution The entire idea of generating the VS solution makes only sense if we generate it via Continuous Integration; otherwise potential users would still have to download the entire Git for Windows SDK. If we pre-generate the Visual Studio solution, Git can be built entirely within Visual Studio, and the test scripts can be run in a regular Git for Windows (e.g. the Portable Git flavor, which does not include a full GCC toolchain and therefore weighs only about a tenth of Git for Windows' SDK). So let's just add a target in the Makefile that can be used to generate said solution; The generated files will then be committed so that they can be pushed to a branch ready to check out by Visual Studio users. To make things even more useful, we also generate and commit other files that are required to run the test suite, such as templates and bin-wrappers: with this, developers can run the test suite in a regular Git Bash after building the solution in Visual Studio. Note: for this build target, we do not actually need to initialize the `vcpkg` system, so we don't.

Jeff Hostetler	dce7d29551	msvc: support building Git using MS Visual C++ With this patch, Git can be built using the Microsoft toolchain, via: make MSVC=1 [DEBUG=1] Third party libraries are built from source using the open source "vcpkg" tool set. See https://github.com/Microsoft/vcpkg On a first build, the vcpkg tools and the third party libraries are automatically downloaded and built. DLLs for the third party libraries are copied to the top-level (and t/helper) directory to facilitate debugging. See compat/vcbuild/README. A series of .bat files are invoked by the Makefile to find the location of the installed version of Visual Studio and the associated compiler tools (essentially replicating the environment setup performed by a "Developer Command Prompt"). This should find the most recent VS2015 or VS2017 installation. Output from these scripts are used by the Makefile to define compiler and linker pathnames and -I and -L arguments. The build produces .pdb files for both debug and release builds. Note: This commit was squashed from an organic series of commits developed between 2016 and 2018 in Git for Windows' `master` branch. This combined commit eliminates the obsolete commits related to fetching NuGet packages for third party libraries. It is difficult to use NuGet packages for C/C++ sources because they may be built by earlier versions of the MSVC compiler and have CRT version and linking issues. Additionally, the C/C++ NuGet packages that we were using tended to not be updated concurrently with the sources. And in the case of cURL and OpenSSL, this could expose us to security issues.

Kirill Smelkov	22f4c27e68	mingw: activate alloca 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.

Ramsay Jones	41f2999180	msvc: Fix compilation errors caused by poll.h emulation 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.

Ramsay Jones	1a3b5a3e5c	msvc: Fix build by adding missing INTMAX_MAX define 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 <stdint.h> 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.

Erik Faye-Lund	d1b6e6e015	win32: use our own dirent.h 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.

Ramsay Jones	38743b7d10	msvc: Fix an "unrecognized option" linker warning Having recently added support for building git-imap-send on Windows, we now link against OpenSSL libraries, and the linker issues the following warning: warning LNK4044: unrecognized option '/lssl'; ignored In order to suppress the warning, we change the msvc linker script to translate an '-lssl' parameter to the ssleay32.lib library. Note that the linker script was already including ssleay32.lib (along with libeay32.lib) as part of the translation of the '-lcrypto' library parameter. However, libeay32.dll does not depend on ssleay32.dll and can be used stand-alone, so we remove ssleay32.lib from the '-lcrypto' translation. The dependence of ssleay32.dll on libeay32.dll is represented in the Makefile by the NEEDS_CRYPTO_WITH_SSL build variable. Also, add the corresponding change to the buildsystem generator.

Ramsay Jones	b5d18b8e6f	Fix the exit code of MSVC build scripts on cygwin During an MSVC build on cygwin, the make program did not notice when the compiler or linker exited with an error. This was caused by the scripts exiting with the value returned by system() directly. On POSIX-like systems, such as cygwin, the return value of system() has the exit code of the executed command encoded in the first byte (ie the value is shifted up by 8 bits). This allows the bottom 7 bits to contain the signal number of a terminated process, while the eighth bit indicates whether a core-dump was produced. (A value of -1 indicates that the command failed to execute.) The make program, however, expects the exit code to be encoded in the bottom byte. Futhermore, it apparently masks off and ignores anything in the upper bytes. However, these scripts are (naturally) intended to be used on the windows platform, where we can not assume POSIX-like semantics from a perl implementation (eg ActiveState). So, in general, we can not assume that shifting the return value right by eight will get us the exit code. In order to improve portability, we assume that a zero return from system() indicates success, whereas anything else indicates failure. Since we don't need to know the exact exit code from the compiler or linker, we simply exit with 0 (success) or 1 (failure).

Marius Storm-Olsen	259d87c354	Add scripts to generate projects for other buildsystems (MSVC vcproj, QMake) These scripts generate projects for the MSVC IDE (.vcproj files) or QMake (.pro files), based on the output of a 'make -n MSVC=1 V=1' run. This enables us to simply do the necesarry changes in the Makefile, and you can update the other buildsystems by regenerating the files. Keeping the other buildsystems up-to-date with main development. The generator system is designed to easily drop in pm's for other buildsystems as well, if someone has an itch. However, the focus has been Windows development, so the 'engine' might need patches to support any platform. Also add some .gitignore entries for MSVC files.
