Subject: [PATCH 2/2] t9902-completion: exercise __git_complete_index_file() directly
Date: Fri, 18 May 2018 16:17:51 +0200 [thread overview]
Message-ID: <20180518141751.16350-3-szeder.dev@gmail.com> (raw)
In-Reply-To: <20180518141751.16350-1-szeder.dev@gmail.com>
The tests added in 2f271cd9cf (t9902-completion: add tests
demonstrating issues with quoted pathnames, 2018-05-08) and in
2ab6eab4fe (completion: improve handling quoted paths in 'git
ls-files's output, 2018-03-28) have a few shortcomings:
- All these test use the 'test_completion' helper function, thus
they are exercising the whole completion machinery, although they
are only interested in how git-aware path completion, specifically
the __git_complete_index_file() function deals with unusual
characters in pathnames and on the command line.
- These tests can't satisfactorily test the case of pathnames
containing spaces, because 'test_completion' gets the words on the
command line as a single argument and it uses space as word
separator.
- Some of the tests are protected by different FUNNYNAMES_* prereqs
depending on whether they put backslashes and double quotes or
separator characters (FS, GS, RS, US) in pathnames, although a
filesystem not allowing one likely doesn't allow the others
either.
- One of the tests operates on paths containing '|' and '&'
characters without being protected by a FUNNYNAMES prereq, but
some filesystems (notably on Windows) don't allow these characters
in pathnames, either.
Replace these tests with basically equivalent, more focused tests that
call __git_complete_index_file() directly. Since this function only
looks at the current word to be completed, i.e. the $cur variable, we
can easily include pathnames containing spaces in the tests, so use
such pathnames instead of pathnames containing '|' and '&'. Finally,
use only a single FUNNYNAMES prereq for all kinds of special
characters.
