"Kevin Lyles via GitGitGadget" <gitgitgadget@gmail.com> writes: > Subject: Re: [PATCH v3 1/2] Allow using stdin in run_on_* functions Imagine that these two commits are applied and appear among hundreds of other commits in the list of contributions. Would this commit title blend in and belong to others? $ git log --oneline --no-merges -100 cf. Documentation/SubmittingPatches:describe-changes. At least, it should somehow hint that the patch is about updating the t1092 test script. Subject: t1092: allow run_on_* functions to use standard input or something. > From: Kevin Lyles <klyles@epic.com> > > The 'run_on_sparse' and 'run_on_all' functions previously did not work > correctly for commands accepting standard input. Our convention is to first describe the status quo in the present tense, so "previously did not" -> "do not". It would be helpful to explain why they do not work, perhaps like so: ... functions do not work for commands that consume their standard input, because they attempt to run the same command in multiple repositories that are set up differently to inspect their behaviour differences. > This also indirectly > affected 'test_all_match' and 'test_sparse_match'. "affected" -> "affects". > Now, we accept standard input and will send it to each command that we > run. This does not impact using the functions for commands that don't > need standard input. And after presenting the observation on the status quo and pointing out the issue we are going to address, it is our convention to write what to do in imperative mood, as if we are ordering the codebase to "become like so". E.g. To allow these commands to consume the standard input, first slurp the contents fed from the standard input to a temporary file, and then run each attempt with its standard input redirected from the temporary file. This way, these multiple attempts will all see the same contents from their standard input. Note that a command that does not read from the standard input does not have to redirect its standard input from </dev/null when using these run_on_* helper functions, as the standard input of the test environment is already connected to /dev/null. or something, perhaps. > Signed-off-by: Kevin Lyles <klyles@epic.com> > --- > t/t1092-sparse-checkout-compatibility.sh | 14 +++++++++----- > 1 file changed, 9 insertions(+), 5 deletions(-) > > diff --git a/t/t1092-sparse-checkout-compatibility.sh b/t/t1092-sparse-checkout-compatibility.sh > index 6fa7f5e9587..87953abf872 100755 > --- a/t/t1092-sparse-checkout-compatibility.sh > +++ b/t/t1092-sparse-checkout-compatibility.sh > @@ -179,22 +179,26 @@ init_repos_as_submodules () { > } > > run_on_sparse () { > + cat >run_on_sparse-input && Mixture of word_with_underscore-and-dash-separation look unexpected; use "run-on-sparse-input" instead, as the output files seem to be named that way? > ( > cd sparse-checkout && > GIT_PROGRESS_DELAY=100000 "$@" >../sparse-checkout-out 2>../sparse-checkout-err > - ) && > + ) <run_on_sparse-input && > ( > cd sparse-index && > GIT_PROGRESS_DELAY=100000 "$@" >../sparse-index-out 2>../sparse-index-err > - ) > + ) <run_on_sparse-input Shouldn't the temporary file be removed at the end, or are the callers expected to live with them?
