From 203439b2840c4c384060df2fa192994e4b6740ed Mon Sep 17 00:00:00 2001 From: Jiang Xin Date: Tue, 25 Jun 2013 23:53:42 +0800 Subject: test: add test cases for relative_path Add subcommand "relative_path" in test-path-utils, and add test cases in t0060. Johannes tested an earlier version of this patch on Windows, and found that some relative_path tests should be skipped on Windows. This is because the bash on Windows rewrites arguments of regular Windows programs, such as git and the test helpers, if the arguments look like absolute POSIX paths. As a consequence, the actual tests performed are not what the tests scripts expect. The tests that need *not* be skipped are those where the two paths passed to 'test-path-utils relative_path' have the same prefix and the result is expected to be a relative path. This is because the rewriting changes "/a/b" to "D:/Src/MSysGit/a/b", and when both inputs are extended the same way, this just cancels out in the relative path computation.

In most cases, we need a real relative path, such as: ../foo, ../../bar. That's why there is another reimplementation (path_relative()) in quote.c. Borrow some codes from path_relative() in quote.c to refactor relative_path() in path.c, so that it could return real relative path, and user can reuse this function without reimplementing his/her own. The function path_relative() in quote.c will be substituted, and I would use the new relative_path() function when implementing the interactive git-clean later. Different results for relative_path() before and after this refactor: abs path base path relative (original) relative (refactor) ======== ========= =================== =================== /a/b /a/b . ./ /a/b/ /a/b . ./ /a /a/b/ /a ../ / /a/b/ / ../../ /a/c /a/b/ /a/c ../c /x/y /a/b/ /x/y ../../x/y a/b/ a/b/ . ./ a/b/ a/b . ./ a a/b a ../ x/y a/b/ x/y ../../x/y a/c a/b a/c ../c (empty) (null) (empty) ./ (empty) (empty) (empty) ./ (empty) /a/b (empty) ./ (null) (null) (null) ./ (null) (empty) (null) ./ (null) /a/b (segfault) ./ You may notice that return value "." has been changed to "./". It is because: * Function quote_path_relative() in quote.c will show the relative path as "./" if abs(in) and base(prefix) are the same. * Function relative_path() is called only once (in setup.c), and it will be OK for the return value as "./" instead of ".".

This is because arguments look like absolute paths (such as /a/b) for regular Windows programs (*.exe executables, no bash scripts) are changed to Windows paths (like C:/msysgit/a/b). There is no cygpath nor equivalent on msysGit, but it is easy to write one. New subcommand "mingw_path" is added in test-path-utils, so that we can get the expected absolute paths on Windows. E.g. COMMAND LINE Linux output Windows output ================================== ============ =============== test-path-utils mingw_path / / C:/msysgit test-path-utils mingw_path /a/b/ /a/b/ C:/msysgit/a/b/ With this utility, most skipped test cases in t0060 can be turned on to be tested correctly on Windows.
