Currently, our default branch in tests is "master". This is the Git
default, but the Git default will likely change in the future, so it
makes sense to update our testsuite to be explicit about the branch
name. We'll ensure this continues by building against older versions of
Git as well as newer versions.
We use "main" for the new branch name, since that's the proposed value
upstream.
This commit was made entirely by automated means using the following
command:
git grep -l master t | xargs sed -i -e 's/master/main/g'
If we're attempting to resume a download but the file we have on disk is
the expected size or too large, we'll send an invalid Range header where
the lower bound is greater than the upper bound. If this situation
occurs, simply retry the download from the beginning, since we clearly
don't have the expected data (or we wouldn't be resuming) and it isn't
clear how else to recover.
The printf(1) command, like it's C cousin, takes a format string as its
first argument. If a shell variable is passed as the first argument, it
will be interpreted as a format string; this can lead to surprising
behavior and can cause the test suite to fail if we accidentally insert
a format string character into the variable.
Modify all the places in the individual tests that we use a plain quoted
variable as the format string by running the following Ruby one-liner:
ruby -i -pe '$_.gsub!(/printf "\$/, %q(printf "%s" "$))' t/t-*.sh
Avoid modifying the test helpers, as there are places (such as calc_oid)
where we want to pass text containing escapes (such as "\n") and have
those be properly interpreted by printf(1).
