"git am -3" uses this function to build a tree that records how the
preimage the patch was created from would have looked like. An
abbreviated object name on the index line is ordinarily sufficient
for us to figure out the object name the preimage tree would have
contained, but a change to a submodule by definition shows an object
name of a submodule commit which our repository should not have, and
get_sha1_blob() is not an appropriate way to read it (or get_sha1()
for that matter).
Use get_sha1_hex() and complain if we do not find a full object name
there.
We could read from the payload part of the patch to learn the full
object name of the commit, but the primary user "git rebase" has
been fixed to give us a full object name, so this should suffice
for now.

The local variable sha1_ptr in the build_fake_ancestor() function
used to either point at the null_sha1[] (if the ancestor did not
have the path) or at sha1[] (if we read the object name into the
local array), but 7a98869 (apply: get rid of --index-info in favor
of --build-fake-ancestor, 2007-09-17) made the "missing in the
ancestor" case unnecessary, hence sha1_ptr, when used, always points
at the local array.
Get rid of the unneeded variable, and restructure the if/else
cascade a bit to make it easier to read. There should be no
behaviour change.

Earlier, a230949 (am --rebasing: get patch body from commit, not
from mailbox, 2012-06-26) learned to regenerate patch body from the
commit object while rebasing, instead of reading from the rebase-am
front-end. While doing so, it used "git diff-tree" but without
giving it the "--full-index" option.
This does not matter for in-repository objects; during rebasing, any
abbreviated object name should uniquely identify them.
But we may be rebasing a commit that contains a change to a gitlink,
in which case we usually should not have the object (it names a
commit in the submodule). A full object name is necessary to later
reconstruct a fake ancestor index for them.

When looking at a configuration file edited long time ago, a user
may find 'pull.default = tracking' and wonder what it means, but
earlier we stopped mentioning this value, even though the code still
support it and more importantly, we have no intention to force old
timers to update their configuration files.
Instead of not mentioning it, add it to the description in a way
that makes it clear that users have no reason to add new uses of it
preferring over 'upstream', by not listing it as a separate item on
the same footing as other values but as a deprecated synonym of the
'upstream' in its description.

Currently, a branch filter like `--contains`, `--merged`, or
`--no-merged` is ignored when we are not in listing mode.
For example:
git branch --contains=foo bar
will create the branch "bar" from the current HEAD, ignoring
the `--contains` argument entirely. This is not very
helpful. There are two reasonable behaviors for git here:
1. Flag an error; the arguments do not make sense.
2. Implicitly go into `--list` mode
This patch chooses the latter, as it is more convenient, and
there should not be any ambiguity with attempting to create
a branch; using `--contains` and not wanting to list is
nonsensical.
That leaves the case where an explicit modification option
like `-d` is given. We already catch the case where
`--list` is given alongside `-d` and flag an error. With
this patch, we will also catch the use of `--contains` and
other filter options alongside `-d`.

These are kept short by simply deferring to PEP-8. Most of the Python
code in Git is already very close to this style (some things in contrib/
are not).
Rationale for version suggestions:
- Amongst the noise in [1], there isn't any disagreement about using
2.6 as a base (see also [2]), although Brandon Casey recently added
support for 2.4 and 2.5 to git-p4 [3].
- Restricting ourselves to 2.6+ makes aiming for Python 3 compatibility
significantly easier [4].
- Advocating Python 3 support in all scripts is currently unrealistic
because:
- 'p4 -G' provides output in a format that is very hard to use with
Python 3 (and its documentation claims Python 3 is unsupported).
- Mercurial does not support Python 3.
- Bazaar does not support Python 3.
- But we should try to make new scripts compatible with Python 3
because all new Python development is happening on version 3 and the
Python community will eventually stop supporting Python 2 [5].
- Python 3.1 is required to support the 'surrogateescape' error handler
for encoding/decodng filenames to/from Unicode strings and Python 3.0
is not longer supported.

Some reimplementations of Git does not write all the stat info back

Long time ago, we used to punt on a large (read: asking for more
than 256 refs) fetch request and instead sent a full pack, because
we couldn't fit many refs on the command line of rev-list we run
internally to enumerate the objects to be sent. To fix this,
565ebbf (upload-pack: tighten request validation., 2005-10-24),
added a check to count the number of refs in the request and matched
with the number of refs we advertised, and changed the invocation of
rev-list to pass "--all" to it, still keeping us under the command
line argument limit.
However, these days we feed the list of objects requested and the
list of objects the other end is known to have via standard input,
so there is no longer a valid reason to special case a full clone
request. Remove the code associated with "create_full_pack" to
simplify the logic.

Most Git commands that can be used with or without pathspec operate
tree-wide by default, the pathspec being used to restrict their
scope. A few exceptions are: 'git grep', 'git clean', 'git add -u'
and 'git add -A'. When run in a subdirectory without pathspec, they
operate only on paths in the current directory.
The inconsistency of 'git add -u' and 'git add -A' is particularly
problematic since other 'git add' subcommands (namely 'git add -p'
and 'git add -e') are tree-wide by default. It also means that "git
add -u && git commit" will record a state that is different from
what is recorded with "git commit -a".
Flipping the default now is unacceptable, so let's start training
users to type 'git add -u|-A :/' or 'git add -u|-A .' explicitly, to
prepare for the next steps:
* forbid 'git add -u|-A' without pathspec (like 'git add' without
option)
* much later, maybe, re-allow 'git add -u|-A' without pathspec, that
will add all tracked and modified files, or all files, tree-wide.
A nice side effect of this patch is that it makes the :/ magic
pathspec easier to discover for users.
When the command is called from the root of the tree, there is no
ambiguity and no need to change the behavior, hence no need to warn.

When this change was originally made (0846b0c - git-remote-testpy:
hash bytes explicitly , I didn't realise that the "hex" encoding we
chose is a "bytes to bytes" encoding so it just fails with an error
on Python 3 in the same way as the original code.
It is not possible to provide a single code path that works on
Python 2 and Python 3 since Python 2.x will attempt to decode the
string before encoding it, which fails for strings that are not
valid in the default encoding. Python 3.1 introduced the
"surrogateescape" error handler which handles this correctly and
permits a bytes -> unicode -> bytes round-trip to be lossless. As
the original came from reading the filesystem path, we convert them
back into the original bytes encoded in sys.getfilesystemencoding().
At this point Python 3.0 is unsupported so we don't go out of our
way to try to support it.
