We have a couple of test scripts that are not completely
httpd-specific, but do run a few httpd-specific tests at the end.
These test scripts source 'lib-httpd.sh' somewhere mid-script, which
then skips all the rest of the test script if the dependencies for
running httpd tests are not fulfilled.
As the previous two patches in this series show, already on two
occasions non-httpd-specific tests were appended at the end of such
test scripts, and, consequently, they were skipped as well when httpd
tests couldn't be run.
Add a comment at the end of these test scripts to warn against adding
non-httpd-specific tests at the end, in the hope that they will help
prevent similar issues in the future.

When fetching into a partial clone, Git first prefetches missing
REF_DELTA bases from the promisor remote. (This feature was introduced
in [1].) But as can be seen in a recent test coverage report [2], the
case in which a REF_DELTA base is already present is not covered by
tests.
Extend the tests slightly to cover this case.

2019-05-15).

If we want to check whether an object is missing, the correct flag to
pass to rev-list is --ignore-missing; --exclude-promisor-objects will
exclude any object that came from the promisor remote, whether it is
present or missing. Use the correct flag.

When fetching, the client sends "have" commit IDs indicating that the
server does not need to send any object referenced by those commits,
reducing network I/O. When the client is a partial clone, the client
still sends "have"s in this way, even if it does not have every object
referenced by a commit it sent as "have".
If a server omits such an object, it is fine: the client could lazily
fetch that object before this fetch, and it can still do so after.
The issue is when the server sends a thin pack containing an object that
is a REF_DELTA against such a missing object: index-pack fails to fix
the thin pack. When support for lazily fetching missing objects was
added in 8b4c0103a9 ("sha1_file: support lazily fetching missing
objects", 2017-12-08), support in index-pack was turned off in the
belief that it accesses the repo only to do hash collision checks.
However, this is not true: it also needs to access the repo to resolve
REF_DELTA bases.
Support for lazy fetching should still generally be turned off in
index-pack because it is used as part of the lazy fetching process
itself (if not, infinite loops may occur), but we do need to fetch the
REF_DELTA bases. (When fetching REF_DELTA bases, it is unlikely that
those are REF_DELTA themselves, because we do not send "have" when
making such fetches.)
To resolve this, prefetch all missing REF_DELTA bases before attempting
to resolve them. This both ensures that all bases are attempted to be
fetched, and ensures that we make only one request per index-pack
invocation, and not one request per missing object.

A subsequent patch will perform the same packfile replacement that is
already done twice, so refactor it into its own function. Also, the same
subsequent patch will use, in another way, part of the packfile
replacement functionality, so extract those out too.

Use 'test_atexit' to run cleanup commands to stop httpd at the end of
the test script or upon interrupt or failure, as it is shorter,
simpler, and more robust than registering such cleanup commands in the
trap on EXIT in the test scripts.

A few trivial updates to test to match the current best practices.
- avoid "grep -q" that strips potentially useful output from tests
running under "-v".
- use test_write_lines to prepare multi-line expected output file.
- reserve use of test_must_fail to "git" commands.

Teach list-objects the "tree:0" filter which allows for filtering
out all tree and blob objects (unless other objects are explicitly
specified by the user). The purpose of this patch is to allow smaller
partial clones.
The name of this filter - tree:0 - does not explicitly specify that
it also filters out all blobs, but this should not cause much confusion
because blobs are not at all useful without the trees that refer to
them.
I also considered only:commits as a name, but this is inaccurate because
it suggests that annotated tags are omitted, but actually they are
included.
The name "tree:0" allows later filtering based on depth, i.e. "tree:1"
would filter out all but the root tree and blobs. In order to avoid
confusion between 0 and capital O, the documentation was worded in a
somewhat round-about way that also hints at this future improvement to
the feature.

It is a common mistake to put positional arguments before flags when
invoking git-rev-list. Order the positional arguments last.
This patch skips git-rev-list invocations which include the --not flag,
since the ordering of flags and positional arguments affects the
behavior. This patch also skips invocations of git-rev-list that occur
in command substitution in which the exit code is discarded, since
fixing those properly will require a more involved cleanup.

Some pipes in tests lose the exit code of git processes, which can mask
unexpected behavior like crashes. Split these pipes up so that git
commands are only at the end of pipes rather than the beginning or
middle.
The violations fixed in this patch were found in the process of fixing
pipe placement in a prior patch.

Instead of using a line-continuation and pipe on the second line, take
advantage of the shell's implicit line continuation after a pipe
character. So for example, instead of
some long line \
| next line
use
some long line |
next line
And add a blank line before and after the pipe where it aids readability
(it usually does).
This better matches the coding style documented in
Documentation/CodingGuidelines and used in shell scripts elsewhere in
the tree.

When fetching an object that is known as a promisor object to the local
repository, the connectivity check in quickfetch() in builtin/fetch.c
succeeds, causing object transfer to be bypassed. However, this should
not happen if that object is merely promised and not actually present.
Because this happens, when a user invokes "git fetch origin <sha-1>" on
the command-line, the <sha-1> object may not actually be fetched even
though the command returns an exit code of 0. This is a similar issue
(but with a different cause) to the one fixed by a0c9016abd
("upload-pack: send refs' objects despite "filter"", 2018-07-09).
Therefore, update quickfetch() to also directly check for the presence
of all objects to be fetched. Its documentation and name are also
updated to better reflect what it does.

deref_tag() prints a warning if the object that a tag refers to does not
exist. However, when a partial clone has an annotated tag from its
promisor remote, but not the object that it refers to, printing a
warning on such a tag is incorrect.
This occurs, for example, when the checkout that happens after a partial
clone causes some objects to be fetched - and as part of the fetch, all
local refs are read. The test included in this patch demonstrates this
situation.
Therefore, do not print a warning in this case.

In handle_commit(), it is fatal for an annotated tag to point to a
non-existent object. --exclude-promisor-objects should relax this rule
and allow non-existent objects that are promisor objects, but this is
not the case. Update handle_commit() to tolerate this situation.
This was observed when cloning from a repository with an annotated tag
pointing to a blob. The test included in this patch demonstrates this
case.

The commit that introduced the partial clone feature - 548719fbdc
("clone: partial clone", 2017-12-08) - excluded connectivity checks
for partial clones, but this also meant that it is possible for a clone
to succeed, yet not have all objects either present or promised.
Specifically, if cloning with --filter=blob:none from a repository that
has a tag pointing to a blob, and the blob is not sent in the packfile,
the clone will pass, even if the blob is not referenced by any tree in
the packfile.
Turn on connectivity checks for partial clone.

A filter line in a request to upload-pack filters out objects regardless
of whether they are directly referenced by a "want" line or not. This
means that cloning with "--filter=blob:none" (or another filter that
excludes blobs) from a repository with at least one ref pointing to a
blob (for example, the Git repository itself) results in output like the
following:
error: missing object referenced by 'refs/tags/junio-gpg-pub'
and if that particular blob is not referenced by a fetched tree, the
resulting clone fails fsck because there is no object from the remote to
vouch that the missing object is a promisor object.
Update both the protocol and the upload-pack implementation to include
all explicitly specified "want" objects in the packfile regardless of
the filter specification.

When doing a partial clone or fetch with transfer.fsckobjects=1, use the
--fsck-objects instead of the --strict flag when invoking index-pack so
that links are not checked, only objects. This is because incomplete
links are expected when doing a partial clone or fetch.
