In d8193743e08 (usage.c: add BUG() function, 2017-05-12), a new macro
was introduced to use for reporting bugs instead of die(). It was then
subsequently used to convert one single caller in 588a538ae55
(setup_git_env: convert die("BUG") to BUG(), 2017-05-12).
The cover letter of the patch series containing this patch
(cf 20170513032414.mfrwabt4hovujde2@sigill.intra.peff.net) is not
terribly clear why only one call site was converted, or what the plan
is for other, similar calls to die() to report bugs.
Let's just convert all remaining ones in one fell swoop.
This trick was performed by this invocation:
sed -i 's/die("BUG: /BUG("/g' $(git grep -l 'die("BUG' \*.c)

Migrate the struct alternate_object_database and all its related
functions to the object store as these functions are easier found in
that header. The migration is just a verbatim copy, no need to
include the object store header at any C file, because cache.h includes
repository.h which in turn includes the object-store.h

Commit 722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03) regressed pushes to
repositories with colon (or semi-colon in Windows in them)
because it adds the repository's main object directory to
GIT_ALTERNATE_OBJECT_DIRECTORIES. The receiver interprets
the colon as a delimiter, not as part of the path, and
index-pack is unable to find objects which it needs to
resolve deltas.
The previous commit introduced a quoting mechanism for the
alternates list; let's use it here to cover this case. We'll
avoid quoting when we can, though. This alternate setup is
also used when calling hooks, so it's possible that the user
may call older git implementations which don't understand
the quoting mechanism. By quoting only when necessary, this
setup will continue to work unless the user _also_ has a
repository whose path contains the delimiter.

This avoids "." and "..", as we already do, but also leaves
room for index-pack to store extra data in the quarantine
area (e.g., for passing back any analysis to be read by the
pre-receive hook).

The presence of the GIT_QUARANTINE_PATH variable lets any
called programs know that they're operating in a temporary
object directory (and where that directory is).

Once objects are added to the object database by a process,
they cannot easily be deleted, as we don't know what other
processes may have started referencing them. We have to
clean them up with git-gc, which will apply the usual
reachability and grace-period checks.
This patch provides an alternative: it helps callers create
a temporary directory inside the object directory, and a
temporary environment which can be passed to sub-programs to
ask them to write there (the original object directory
remains accessible as an alternate of the temporary one).
See tmp-objdir.h for details on the API.
