Commit 0696232390 (pack-redundant: fix crash when one packfile in repo,
2020-12-16) added one some new tests to t5323. At the time, the sub-repo
we used was called "master". But in a parallel branch, this was switched
to "main".
When the latter branch was merged in 27d7c8599b (Merge branch
'js/default-branch-name-tests-final-stretch', 2021-01-25), some of those
spots caused textual conflicts, but some (for tests that were far enough
away from other changed code) were just semantic. The merge resolution
fixed up most spots, but missed this one.
Even though this did impact actual code, it turned out not to fail the
tests. Running 'cd "$master_repo"' ended up staying in the same
directory, running the test in the main trash repo instead of the
sub-repo. But because the point of the test is checking behavior when
there are no packfiles, it worked in either repo (since both are empty
at this point in the script).

Carefully excluding t5310, which is developed independently of the
current patch series at the time of writing, we now use `main` as
default branch in t5[0-4]*. This trick was performed via
$ (cd t &&
sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
-e 's/Master/Main/g' -- t5[0-4]*.sh &&
git checkout HEAD -- t5310\*)
This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.

We are about to search-and-replace all mentions of `master` in t5323 by
`main`, which is two characters shorter. To prepare for that, let's add
padding to centered lines that will make them briefly uncentered, but
will be re-centered in the commit that performs that rename.
Doing it this way (instead of padding after replacing) makes it easier
to verify the validity of the patch that replaces `master` by `main`.

Warn loudly when the "pack-redundant" command, which has been left
stale with almost unusable performance issues, gets used, as we no
longer want to recommend its use (instead just "repack -d" instead).

pack-redundant: gauge the usage before proposing its removal

The subcommand is unusably slow and the reason why nobody reports it
as a performance bug is suspected to be the absense of users. Let's
show a big message that asks the user to tell us that they still
care about the command when an attempt is made to run the command,
with an escape hatch to override it with a command line option.
In a few releases, we may turn it into an error and keep it for a
few more releases before finally removing it (during the whole time,
the plan to remove it would be interrupted by end user raising hand).

Command `git pack-redundant --all` will crash if there is only one
packfile in the repository. This is because, if there is only one
packfile in local_packs, `cmp_local_packs` will do nothing and will
leave `pl->unique_objects` as uninitialized.
Also add testcases for repository with no packfile and one packfile
in t5323.

SZEDER reported that test case t5323 has different test result on MacOS.
This is because `cmp_pack_list_reverse` cannot give identical result
when two pack being sorted has the same size of remaining_objects.
Changes to the sorting function will make consistent test result for
t5323.
The new algorithm to find redundant packs is a trade-off to save memory
resources, and the result of it may be different with old one, and may
be not the best result sometimes. Update t5323 for the new algorithm.

When calling `git pack-redundant --all`, if there are too many local
packs and too many redundant objects within them, the too deep iteration
of `get_permutations` will exhaust all the resources, and the process of
`git pack-redundant` will be killed.
The following script could create a repository with too many redundant
packs, and running `git pack-redundant --all` in the `test.git` repo
will die soon.
#!/bin/sh
repo="$(pwd)/test.git"
work="$(pwd)/test"
i=1
max=199
if test -d "$repo" || test -d "$work"; then
echo >&2 "ERROR: '$repo' or '$work' already exist"
exit 1
fi
git init -q --bare "$repo"
git --git-dir="$repo" config gc.auto 0
git --git-dir="$repo" config transfer.unpackLimit 0
git clone -q "$repo" "$work" 2>/dev/null
while :; do
cd "$work"
echo "loop $i: $(date +%s)" >$i
git add $i
git commit -q -sm "loop $i"
git push -q origin HEAD:master
printf "\rCreate pack %4d/%d\t" $i $max
if test $i -ge $max; then break; fi
cd "$repo"
git repack -q
if test $(($i % 2)) -eq 0; then
git repack -aq
pack=$(ls -t $repo/objects/pack/*.pack | head -1)
touch "${pack%.pack}.keep"
fi
i=$((i+1))
done
printf "\ndone\n"
To get the `min` unique pack list, we can replace the iteration in
`minimize` function with a new algorithm, and this could solve this
issue:
1. Get the unique and non_uniqe packs, add the unique packs to the
`min` list.
2. Remove the objects of unique packs from non_unique packs, then each
object left in the non_unique packs will have at least two copies.
3. Sort the non_unique packs by the objects' size, more objects first,
and add the first non_unique pack to `min` list.
4. Drop the duplicated objects from other packs in the ordered
non_unique pack list, and repeat step 3.
Some test cases will fail on Mac OS X. Mark them and will resolve in
later commit.
