mingw: add a regression test for pushing to UNC paths

dscho · gitster · commit 16615f0fbc44 · 2017-01-07T13:39:29.000-08:00
On Windows, there are "UNC paths" to access network (AKA shared) folders, of the form \\server\sharename\directory. This provides a convenient way for Windows developers to share their Git repositories without having to have a dedicated server. Git for Windows v2.11.0 introduced a regression where pushing to said UNC paths no longer works, although fetching and cloning still does, as reported here: git-for-windows#979 This regression was fixed in 7814fbe (normalize_path_copy(): fix pushing to //server/share/dir on Windows, 2016-12-14). Let's make sure that it does not regress again, by introducing a test that uses so-called "administrative shares": disk volumes are automatically shared under certain circumstances, e.g. the C: drive is shared as \\localhost\c$. The test needs to be skipped if the current directory is inaccessible via said administrative share, of course.
