As some issues that can happen with a Git client can be operating system specific, it can be useful for a server to know which OS a client is using. In the same way it can be useful for a client to know which OS a server is using. Our current agent capability is in the form of "package/version" (e.g., "git/1.8.3.1"). Let's extend it to include the operating system name (os) i.e in the form "package/version-os" (e.g., "git/1.8.3.1-Linux"). Including OS details in the agent capability simplifies implementation, maintains backward compatibility, avoids introducing a new capability, encourages adoption across Git-compatible software, and enhances debugging by providing complete environment information without affecting functionality. The operating system name is retrieved using the 'sysname' field of the `uname(2)` system call or its equivalent. However, there are differences between `uname(1)` (command-line utility) and `uname(2)` (system call) outputs on Windows. These discrepancies complicate testing on Windows platforms. For example: - `uname(1)` output: MINGW64_NT-10.0-20348.3.4.10-87d57229.x86_64\ .2024-02-14.20:17.UTC.x86_64 - `uname(2)` output: Windows.10.0.20348 On Windows, uname(2) is not actually system-supplied but is instead already faked up by Git itself. We could have overcome the test issue on Windows by implementing a new `uname` subcommand in `test-tool` using uname(2), but except uname(2), which would be tested against itself, there would be nothing platform specific, so it's just simpler to disable the tests on Windows.
