The plan for the push.default transition had all along been
to use the "simple" method rather than "upstream" as a
default if the user did not specify their own push.default
value. Commit 11037ee (push: switch default from "matching"
to "simple", 2013-01-04) tried to implement that by moving
PUSH_DEFAULT_UNSPECIFIED in our switch statement to
fall-through to the PUSH_DEFAULT_SIMPLE case.
When the commit that became 11037ee was originally written,
that would have been enough. We would fall through to
calling setup_push_upstream() with the "simple" parameter
set to 1. However, it was delayed for a while until we were
ready to make the transition in Git 2.0.
And in the meantime, commit ed2b182 (push: change `simple`
to accommodate triangular workflows, 2013-06-19) threw a
monkey wrench into the works. That commit drops the "simple"
parameter to setup_push_upstream, and instead checks whether
the global "push_default" is PUSH_DEFAULT_SIMPLE. This is
right when the user has explicitly configured push.default
to simple, but wrong when we are a fall-through for the
"unspecified" case.
We never noticed because our push.default tests do not cover
the case of the variable being totally unset; they only
check the "simple" behavior itself.

When synchronizing between working directories, it can be handy to update
the current branch via 'push' rather than 'pull', e.g. when pushing a fix
from inside a VM, or when pushing a fix made on a user's machine (where
the developer is not at liberty to install an ssh daemon let alone know
the user's password).
The common workaround – pushing into a temporary branch and then merging
on the other machine – is no longer necessary with this patch.

Update the working tree accordingly, but refuse to do so if there

The function sometimes returns a newly allocated string and
sometimes returns a borrowed string, the latter of which the callers
must not free(). The existing callers all assume that the return
value belongs to the callee and most of them copy it with strdup()
when they want to keep it around. They end up leaking the returned
copy when the callee returned a new string because they cannot tell
if they should free it.
Change the contract between the callers and system_path() to make
the returned string owned by the callers; they are responsible for
freeing it when done, but they do not have to make their own copy to
store it away.
Adjust the callers to make sure they do not leak the returned string
once they are done, but do not bother freeing it just before dying,
exiting or exec'ing other program to avoid unnecessary churn.

Some file systems do not support the executable bit:
a) The user executable bit is always 0, e.g. VFAT mounted with
-onoexec
b) The user executable bit is always 1, e.g. cifs mounted with
-ofile_mode=0755
c) There are system where user executable bit is 1 even if it
should be 0 like b), but the file mode can be maintained
locally. chmod -x changes the file mode from 0766 to 0666,
until the file system is unmounted and remounted and the file
mode is 0766 again.
This been observed when a Windows machine with NTFS exports a share to
Mac OS X via smb or afp.
Case a) and b) are handled by the current code. Case c) qualifies
as "non trustable executable bit" and core.filemode should be false,
but this is currently not done.
Detect when ".git/config" has the user executable bit set after
creat(".git/config", 0666) and set core.filemode to false. Because
the permission bits on the file is whatever the end user already had
when we are asked to reinitialise an existing repository, and do not
give any information on the filesystem behaviour, do this only when
running "git init" to create a new repository.

"git add foo bar" adds neither foo nor bar when bar is ignored, but dies
to let the user recheck their command invocation. This becomes less
helpful when "git add foo.*" is subject to shell expansion and some of
the expanded files are ignored.
"git add --ignore-errors" is supposed to ignore errors when indexing
some files and adds the others. It does ignore errors from actual
indexing attempts, but does not ignore the error "file is ignored" as
outlined above. This is unexpected.
Change "git add foo bar" to add foo when bar is ignored, but issue
a warning and return a failure code as before the change.
That is, in the case of trying to add ignored files we now act the same
way (with or without "--ignore-errors") in which we act for more
severe indexing errors when "--ignore-errors" is specified.

Most of git-config's command line options use OPT_BIT to
choose an action, and then parse the non-option arguments
in a context-dependent way. However, --get-color and
--get-colorbool are unlike the rest of the options, in that
they are OPT_STRING, taking the option name as a parameter.
This generally works, because we then use the presence of
those strings to set an action bit anyway. But it does mean
that the option-parser will continue looking for options
even after the key (because it is not a non-option; it is an
argument to an option). And running:
git config --get-color some.key -1
(to use "-1" as the default color spec) will barf, claiming
that "-1" is not an option. Instead, we should treat
--get-color and --get-colorbool as action bits, just like
--add, --get, and all the other actions, and then check that
the non-option arguments we got are sane. This fixes the
weirdness above, and makes those two options like all the
others.
This "fixes" a test in t4026, which checked that feeding
"-2" as a color should fail (it does fail, but prior to this
patch, because parseopt barfed, not because we actually ever
tried to parse the color).
This also catches other errors, like:
git config --get-color some.key black blue
which previously silently ignored "blue" (and now will
complain that you gave too many arguments).
There are some possible regressions, though. We now disallow
these, which currently do what you would expect:
# specifying other options after the action
git config --get-color some.key --file whatever
# using long-arg syntax
git config --get-color=some.key
However, we have never advertised these in the
documentation, and in fact they did not work in some older
versions of git. The behavior was apparently switched as an
accidental side effect of d64ec16 (git config: reorganize to
use parseopt, 2009-02-21).

Since time immemorial, the test of whether to set "core.filemode"
has been done by trying to toggle the u+x bit on $GIT_DIR/config,
which we know always exists, and then testing whether the change
"took". I find it somewhat odd to use the config file for this
test, but whatever.
The test code didn't set the u+x bit back to its original state
itself, instead relying on the subsequent call to git_config_set()
to re-write the config file with correct permissions.
But ever since
daa22c6f8d config: preserve config file permissions on edits (2014-05-06)
git_config_set() copies the permissions from the old config file to
the new one. This is a good change in and of itself, but it
invalidates the create_default_files()'s assumption, causing "git
init" to leave the executable bit set on $GIT_DIR/config.
Reset the permissions on $GIT_DIR/config when we are done with the
test in create_default_files().

When we "git checkout $tree", we pull paths from $tree into
the index, and then check the resulting entries out to the
worktree. Our method for the first step is rather
heavy-handed, though; it clobbers the entire existing index
entry, even if the content is the same. This means we lose
our stat information, leading checkout_entry to later
rewrite the entire file with identical content.
Instead, let's see if we have the identical entry already in
the index, in which case we leave it in place. That lets
checkout_entry do the right thing. Our tests cover two
interesting cases:
1. We make sure that a file which has no changes is not
rewritten.
2. We make sure that we do update a file that is unchanged
in the index (versus $tree), but has working tree
changes. We keep the old index entry, and
checkout_entry is able to realize that our stat
information is out of date.

create_note() has a non-trivial interface, and comprises three loosely
related parts:
1. launching the editor with the note contents, if needed
2. appending to an existing note, if append_only was given
3. adding or removing the resulting note, based on whether it's non-empty
Split it along those lines to make the logic clearer: The first part
goes into a new function - prepare_note_data(), with a simpler interface.
The second part is moved into append_edit(), which is the only user of
this code. Finally, the add vs. remove decision is moved into the callers
(add() and append_edit()), keeping the logic for writing the actual note
object in a separate function: write_note_data().
