Revision 976aaedca0c6f64b37f4241bf06fa7ab06095986 authored by Johannes Schindelin on 29 July 2019, 20:08:12 UTC, committed by Junio C Hamano on 29 July 2019, 21:51:43 UTC
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.

/*
* The size parameter specifies the available space, i.e. includes
* the trailing NUL byte; but Windows's vsnprintf uses the entire
* buffer and avoids the trailing NUL, should the buffer be exactly
* big enough for the result. Defining SNPRINTF_SIZE_CORR to 1 will
* therefore remove 1 byte from the reported buffer size, so we
* always have room for a trailing NUL byte.
