Subject: [RFC PATCH v2 01/12] t7300: Add some testcases showing failure to clean specified pathspecs
Date: Thu,  5 Sep 2019 08:47:24 -0700
Message-ID: <20190905154735.29784-2-newren@gmail.com> (raw)
In-Reply-To: <20190905154735.29784-1-newren@gmail.com>

Someone brought me a testcase where multiple git-clean invocations were
required to clean out unwanted files:
  mkdir d{1,2}
  touch d{1,2}/ut
  touch d1/t && git add d1/t
With this setup, the user would need to run
  git clean -ffd */ut
twice to delete both ut files.

A little testing showed some interesting variants:
  * If only one of those two ut files existed (either one), then only one
    clean command would be necessary.
  * If both directories had tracked files, then only one git clean would
    be necessary to clean both files.
  * If both directories had no tracked files then the clean command above
    would never clean either of the untracked files despite the pathspec
    explicitly calling both of them out.

A bisect showed that the failure to clean out the files started with
commit cf424f5fd89b ("clean: respect pathspecs with "-d", 2014-03-10).
However, that pointed to a separate issue: while the "-d" flag was used
by the original user who showed me this problem, that flag should have
been irrelevant to this problem.  Testing again without the "-d" flag
showed that the same buggy behavior exists without using that flag, and
has in fact existed since before cf424f5fd89b.

Add testcases showing that multiple untracked files within entirely
untracked directories cannot be cleaned when specifying these files to
git clean via pathspecs.
