Our usual shell style is to put the "do" of a loop on its
own line, like:
while $cond
do
something
done
instead of:
while $cond; do
something
done
We have a bit of both in our code base, but the former is
what's in CodingGuidelines (and outnumbers the latter in t/
by about 6:1).

If certain options like --honor-pack-keep, --local, or
--incremental are used with pack-objects, then we need to
feed each potential object to want_object_in_pack() to see
if it should be filtered out. But when the bitmap
reuse_packfile optimization is in effect, we do not call
that function at all, and in fact skip adding the objects to
the to_pack list entirely. This means we have a bug: for
certain requests we will silently ignore those options and
include objects in that pack that should not be there.
The problem has been present since the inception of the
pack-reuse code in 6b8fda2db (pack-objects: use bitmaps when
packing objects, 2013-12-21), but it was unlikely to come up
in practice. These options are generally used for on-disk
packing, not transfer packs (which go to stdout), but we've
never allowed pack reuse for non-stdout packs (until
645c432d6, we did not even use bitmaps, which the reuse
optimization relies on; after that, we explicitly turned it
off when not packing to stdout).
We can fix this by just disabling the reuse_packfile
optimization when the options are in use. In theory we could
teach the pack-reuse code to satisfy these checks, but it's
not worth the complexity. The purpose of the optimization is
to keep the amount of per-object work we do to a minimum.
But these options inherently require us to search for other
copies of each object, drowning out any benefit of the
pack-reuse optimization. But note that the optimizations
from 56dfeb626 (pack-objects: compute local/ignore_pack_keep
early, 2016-07-29) happen before pack-reuse, meaning that
specifying "--honor-pack-keep" in a repository with no .keep
files can still follow the fast path.
There are tests in t5310 that check these options with
bitmaps and --stdout, but they didn't catch the bug, and
it's hard to adapt them to do so.
One problem is that they don't use --delta-base-offset;
without that option, we always disable the reuse
optimization entirely. It would be fine to add it in (it
actually makes the test more realistic), but that still
isn't quite enough.
The other problem is that the reuse code is very picky; it
only kicks in when it can reuse most of a pack, starting
from the first byte. So we'd have to start from a fully
repacked and bitmapped state to trigger it. But the tests
for these options use a much more subtle state; they want to
be sure that the want_object_in_pack() code is allowing some
objects but not others. Doing a full repack runs counter to
that.
So this patch adds new tests at the end of the script which
create the fully-packed state and make sure that each option
is not fooled by reusable pack.

The `perforce` and `perforce-server` package were moved from brew [1][2]

Perforce updates their binaries without version bumps. That made the

workaround is not necessary anymore as Cask [4] allows to disable the
checksum test for individual formulas.

When looking for documentation for a specific function, you may be tempted
to run
git -C Documentation grep index_name_pos
only to find the file technical/api-in-core-index.txt, which doesn't
help for understanding the given function. It would be better to not find
these functions in the documentation, such that people directly dive into
the code instead.
In the previous patches we have documented
* index_name_pos()
* remove_index_entry_at()
* add_[file_]to_index()
in cache.h
We already have documentation for:
* add_index_entry()
* read_index()
Which leaves us with a TODO for:
* cache -> the_index macros
* refresh_index()
* discard_index()
* ie_match_stat() and ie_modified(); how they are different and when to
use which.
* write_index() that was renamed to write_locked_index
* cache_tree_invalidate_path()
* cache_tree_update()

The version of the "replace isatty() hack" that got merged a few
weeks ago did not actually reflect the latest iteration of the patch
series: v3 was sent out with these changes, as requested by the
reviewer Johannes Sixt:
- reworded the comment about "recycling handles"
- moved the reassignment of the `console` variable before the dup2()
call so that it is valid at all times
- removed the "handle = INVALID_HANDLE_VALUE" assignment, as the local
variable `handle` is not used afterwards anyway
