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
to the index due to their implementation limitations (e.g. jgit
running on Java). A configuration option can tell Git to ignore
changes to most of the stat fields and only pay attention to mtime
and size, which these implementations can reliably update. This
avoids excessive revalidation of contents.

gitk, when bound into the git.git project tree, used to live at the
root level, but in 62ba514 (Move gitk to its own subdirectory,
2007-11-17) it was moved to a subdirectory. The code used to track
changes to TCLTK_PATH (which should cause gitk to be rebuilt to
point at the new interpreter) was left in the main Makefile instead
of being moved to the new Makefile that was created for the gitk
project.

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.

This will make it easier to use setup_tool in places where we expect
that the selected tool will not support the current mode.
We need to introduce a new return code for setup_tool to differentiate
between the case of "the selected tool is invalid" and "the selected
tool is not a built-in" since we must call setup_tool when a custom
'merge.<tool>.path' is configured for a built-in tool but avoid failing
when the configured tool is not a built-in.

This test does a commit that is a pure mode change, submits
it to p4 but causes the submit to fail. It verifies that
the state in p4 as well as the client directory are both
unmodified after the failed submit.
On cygwin, "chmod +x" does nothing, so use the test_chmod
function to modify the index directly too.
Also on cygwin, the executable bit cannot be seen in the
filesystem, so avoid that part of the test. The checks of
p4 state are still valid, though.
