From d79b14556922e5b7139268e92f2dface8d174278 Mon Sep 17 00:00:00 2001 From: Shourya Shukla Date: Thu, 27 Aug 2020 23:15:01 +0530 Subject: t7421: eliminate 'grep' check in t7421.4 for mingw compatibility The 'grep' check in test 4 of t7421 resulted in the failure of t7421 on Windows due to a different error message error: cannot spawn git: No such file or directory instead of fatal: exec 'rev-parse': cd to 'my-subm' failed: No such file or directory Tighten up the check to compute 'src_abbrev' by guarding the 'verify_submodule_committish()' call using `p->status !='D'`, so that the former isn't called in case of non-existent submodule directory, consequently, there is no such error message on any execution environment. The same need not be implemented for 'dst_abbrev' and is rather redundant since the conditional 'if (S_ISGITLINK(p->mod_dst))' already guards the 'verify_submodule_committish()' when we have a status of 'D'. Therefore, eliminate the 'grep' check in t7421. Instead, verify the absence of an error message by doing a 'test_must_be_empty' on the file containing the error.
