To figure out the author ident for a commit, we call
determine_author_info(). This function collects information
from the environment, other commits (in the case of
"--amend" or "-c/-C"), and the "--author" option. It then
uses fmt_ident to generate the final ident string that goes
into the commit object. fmt_ident is therefore responsible
for any quality or validation checks on what is allowed to
go into a commit.
Before returning, though, we call split_ident_line on the
result, and feed the individual components to hooks via the
GIT_AUTHOR_* variables. Furthermore, we do extra validation
by feeding the split to sane_ident_split(), which is pickier
than fmt_ident (in particular, it will complain about an empty
email field). If this parsing or validation fails, we skip
updating the environment variables.
This is bad, because it means that hooks may silently see a
different ident than what we are putting into the commit. We
should drop the extra sane_ident_split checks entirely, and
take whatever fmt_ident has fed us (and what will go into
the commit object).
If parsing fails, we should actually abort here rather than
continuing (and feeding the hooks bogus data). However,
split_ident_line should never fail here. The ident was just
generated by fmt_ident, so we know that it's sane. We can
use assert_split_ident to double-check this.
Note that we also teach that assertion to check that we
found a date (it always should, but until now, no caller
cared whether we found a date or not). Checking the return
value of sane_ident_split is enough to ensure we have the
name/email pointers set, and checking date_begin is enough
to know that all of the date/tz variables are set.

When we generate the commit-message template, we try to
report an author or committer ident that will be of interest
to the user: an author that does not match the committer, or
a committer that was auto-configured.
When doing so, if we encounter what we consider to be a
bogus ident, we immediately die. This is a bad idea, because
our use of the idents here is purely informational. Any
ident rules should be enforced elsewhere, because commits
that do not invoke the editor will not even hit this code
path (e.g., "git commit -mfoo" would work, but "git commit"
would not). So at best, we are redundant with other checks,
and at worse, we actively prevent commits that should
otherwise be allowed.
We should therefore do the minimal parsing we can to get a
value and not do any validation (i.e., drop the call to
sane_ident_split()).
In theory we could notice when even our minimal parsing
fails to work, and do the sane thing for each check (e.g.,
if we have an author but can't parse the committer, assume
they are different and print the author). But we can
actually simplify this even further.
We know that the author and committer strings we are parsing
have been generated by us earlier in the program, and
therefore they must be parseable. We could just call
split_ident_line without even checking its return value,
knowing that it will put _something_ in the name/mail
fields. Of course, to protect ourselves against future
changes to the code, it makes sense to turn this into an
assert, so we are not surprised if our assumption fails.

If "git update-ref --stdin" was given a "verify" command with no
"<newvalue>" at all (not even zeros), the code was mistakenly setting
have_old=0 (and leaving old_sha1 uninitialized). But this is
incorrect: this command is supposed to verify that the reference
doesn't exist. So in this case we really need old_sha1 to be set to
null_sha1 and have_old to be set to 1.
Moreover, since have_old was being set to zero, *no* check of the old
value was being done, so the new value of the reference was being set
unconditionally to the value in new_sha1. new_sha1, in turn, was set
to null_sha1 in the expectation that that was the old value and it
shouldn't be changed. But because the precondition was not being
checked, the result was that the reference was being deleted
unconditionally.
So, if <oldvalue> is missing, set have_old unconditionally and set
old_sha1 to null_sha1.

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.

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.

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.

Although the "git notes" man page advertises that we support binary-safe
notes addition (using the -C option), we currently do not support adding
the empty note (i.e. using the empty blob to annotate an object). Instead,
an empty note is always treated as an intent to remove the note
altogether.
Introduce the --allow-empty option to the add/append/edit subcommands,
to explicitly allow an empty note to be stored into the notes tree.
Also update the documentation, and add test cases for the new option.

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().

In preparation for some needed refactoring, rename struct msg_arg to
struct note_data, and rename its instances from "msg" to "d" (also
removing some unnecessary parentheses). The 'msg_arg' name was
inherited from tag.c, but is not really a good name for the contents
of a note.
Also rename write_note_data() to copy_obj_to_fd(), which more aptly
describes what it actually does: Copying the contents of a git object
(given by its SHA1) into a given file descriptor.

This fixes a small buglet when trying to explicitly add the empty blob
as a note object using the -c or -C option to git notes add/append.
Instead of failing with a nonsensical error message indicating that the
empty blob does not exist, we should rather behave as if an empty notes
message was given (e.g. using -m "" or -F /dev/null).
The next patch contains a test that verifies the fixed behavior.

fetch: load all default config at startup
When we start the git-fetch program, we call git_config to
load all config, but our callback only processes the
fetch.prune option; we do not chain to git_default_config at
all.
This means that we may not load some core configuration
which will have an effect. For instance, we do not load
core.logAllRefUpdates, which impacts whether or not we
create reflogs in a bare repository.
Note that I said "may" above. It gets even more exciting. If
we have to transfer actual objects as part of the fetch,
then we call fetch_pack as part of the same process. That
function loads its own config, which does chain to
git_default_config, impacting global variables which are
used by the rest of fetch. But if the fetch is a pure ref
update (e.g., a new ref which is a copy of an old one), we
skip fetch_pack entirely. So we get inconsistent results
depending on whether or not we have actual objects to
transfer or not!
Let's just load the core config at the start of fetch, so we
know we have it (we may also load it again as part of
fetch_pack, but that's OK; it's designed to be idempotent).
Our tests check both cases (with and without a pack). We
also check similar behavior for push for good measure, but
it already works as expected.

The callers of get_merge_bases() can choose to leave object flags
used during the merge-base traversal by passing cleanup=0 as a
parameter, but in practice a very few callers can afford to do so
(namely, "git merge-base"), as they need to compute merge base in
preparation for other processing of their own and they need to see
the object without contaminate flags.
Change the function signature of get_merge_bases_many() and
get_merge_bases() to drop the cleanup parameter, so that the
majority of the callers do not have to say ", 1" at the end.
Give a new get_merge_bases_many_dirty() API to support only a few
callers that know they do not need to spend cycles cleaning up the
object flags.

Just like other hints such as "Changes to be committed" we show in
the editor to remind the committer what paths were involved in the
resulting commit to help improving their log message, this section
is merely a reminder.
Traditionally, it was not made into comments primarily because it
has to be generated outside the wt-status infrastructure, and also
because it was meant as a bit stronger reminder than the others
(i.e. explaining how you resolved conflicts is much more important
than mentioning what you did to every paths involved in the commit).
But that still does not make this hint a part of the log message
proper, and not showing it as a comment is inviting mistakes.
Note that we still notice "Conflicts:" followed by list of indented
pathnames as an old-style cruft and insert a new Signed-off-by:
before it. This is so that "commit --amend -s" adds the new S-o-b
at the right place when used on an older commit.

a HT indented pathname to avoid false positive, but this logic will
