"log --pretty" documentation: do not forget "tformat:"
We forgot to list "tformat:<string>" when enumerating possible
values that "--pretty=<format>" can take. It was not described
that "--pretty='string with %s placeholder'" that is not understood
is DWIMmed as "--pretty=tformat:<that string>".
Further, it was unclear what "When omitted, defaults to 'medium'"
was meant. Is it "When --pretty=<something> was not given at all",
or is it "When --pretty is given without =<something>"? Clarify
that it is the latter.
Even though "advice.h" includes "git-compat-util.h", it is not
sensible to have it as the first #include and indirectly satisify
the "You must give git-compat-util.h a clean environment to set up
feature test macros before including any of the system headers are
included", which is the real requirement.
Because:
- A command that interacts with the object store, config subsystem,
the index, or the working tree cannot do anything without using
what is declared in "cache.h";
- A built-in command must be declared in "builtin.h", so anything
in builtin/*.c must include it;
- These two headers both include "git-compat-util.h" as the first
thing; and
- Almost all our *.c files (outside compat/ and borrowed files in
xdiff/) need some Git-ness from "cache.h" to do something
Git-ish.
let's explicitly specify that one of these three header files must
be the first thing that is included.
Any of our *.c file should include the header file that directly
declares what it uses, instead of relying on the fact that some *.h
file it includes happens to include another *.h file that declares
the necessary function or type. Spell it out as another guideline
item.

For some unknown reason, the dd on my Windows box segfaults randomly,
but since recently, it does so much more often than it used to, which
makes running the test suite burdensome.
Use printf to write large files instead of dd. To emphasize that three
of the large blobs are exact copies, use cp to allocate them.
The new code makes the files a bit smaller, and they are not sparse
anymore, but the tests do not depend on these properties. We do not want
to use test-genrandom here (which is used to generate large files
elsewhere in t1050), so that the files can be compressed well (which
keeps the run-time short).
The files are now large text files, not binary files. But since they
are larger than core.bigfilethreshold they are diagnosed as binary
by Git. For this reason, the 'git diff' tests that check the output
for "Binary files differ" still pass.

http-push: trim trailing newline from remote symref
When we fetch a symbolic ref file from the remote, we get
the whole string "ref: refs/heads/master\n", recognize it by
skipping past the "ref: ", and store the rest. We should
chomp the trailing newline.
This bug was introduced in ae021d8 (use skip_prefix to avoid
magic numbers, 2014-06-18), which did not notice that the
length computation fed to xmemdupz was quietly tweaked by 1
to account for this.
We can solve it by explicitly trimming the newline, which is
more obvious. Note that we use strbuf_rtrim here, which will
actually cut off any trailing whitespace, not just a single
newline. This is a good thing, though, as it makes our
parsing more liberal (and spaces are not valid in refnames
anyway).

"git log --grep=<string>" shows only commits with messages that
match the given string, but sometimes it is useful to be able to
show only commits that do *not* have certain messages (e.g. "show
me ones that are not FIXUP commits").
Originally, we had the invert-grep flag in grep_opt, but because
"git grep --invert-grep" does not make sense except in conjunction
with "--files-with-matches", which is already covered by
"--files-without-matches", it was moved it to revisions structure.
To have the flag there expresses the function to the feature better.
When the newly inserted two tests run, the history would have commits
with messages "initial", "second", "third", "fourth", "fifth", "sixth"

It's a common idiom to duplicate a string if it is non-NULL,
or pass a literal NULL through. This is already a one-liner
in C, but you do have to repeat the name of the string
twice. So if there's a function call, you must write:
doc: core.ignoreStat update, and clarify the --assume-unchanged effect
The assume-unchanged bit, and consequently core.ignoreStat, can be
misunderstood. Be assertive about the expectation that file changes should
notified to Git.
Overhaul the general wording thus:
1. direct description of what is ignored given first.
2. example instruction of the user manual action required.
3. use sideways indirection for assume-unchanged and update-index
references.
4. add a 'normally' to give leeway for the change detection.

for-each-ref: always check stat_tracking_info()'s return value
The code handling %(upstream:track) and %(upstream:trackshort)
assumed that it always had a valid branch that had been sanitized
earlier in populate_value(), and thus did not check the return value
of the call to stat_tracking_info().
While there is indeed some sanitization code that basically
corresponds to stat_tracking_info() returning 0 (no base branch
set), the function can also return -1 when the base branch did exist
but has since then been deleted.
In this case, num_ours and num_theirs had undefined values and a
call to `git for-each-ref --format="%(upstream:track)"` could print
spurious values such as
Verify stat_tracking_info()'s return value and do not print anything
if it returns -1. This behavior also matches the documentation ("has

gettext.h: add parentheses around N_ expansion if supported
The gettext N_ macro is used to mark strings for translation
without actually translating them. At runtime the string is
expected to be passed to the gettext API for translation.
If two N_ macro invocations appear next to each other with only
whitespace (or nothing at all) between them, the two separate
strings will be marked for translation, but the preprocessor
will then silently combine the strings into one and at runtime
the string passed to gettext will not match the strings that
were translated so no translation will actually occur.
Avoid this by adding parentheses around the expansion of the
N_ macro so that instead of ending up with two adjacent strings
that are then combined by the preprocessor, two adjacent strings
surrounded by parentheses result instead which causes a compile
error so the mistake can be quickly found and corrected.
However, since these string literals are typically assigned to
static variables and not all compilers support parenthesized
string literal assignments, allow this to be controlled by the
Makefile with the default only enabled when the compiler is
known to support the syntax.
For now only __GNUC__ enables this by default which covers both
gcc and clang which should result in early detection of any
adjacent N_ macros.
Although the necessary tests make the affected files a bit less
elegant, the benefit of avoiding propagation of a translation-
marking error to all the translation teams thus creating extra
work for them when the error is eventually detected and fixed
would seem to outweigh the minor inelegance the additional
configuration tests introduce.

- "exec_cmd.h" became unnecessary at b931aa5a (Call builtin ls-tree

We should have removed the include in the same commit, but we

- "tag.h" and "tree.h" were necessary since 8e440259 (Use blob_,

the type of object by comparing typename with tree_type and
tag_type (pointers to extern strings).
21666f1a (convert object type handling from a string to a number,

could have switched to include "object.h", which is necessary to
use typename(), but it forgot to do so. Because "tag.h" and
"tree.h" include "object.h", it did not need to explicitly
include "object.h" in order to start using typename() itself.
We do not even have to include "object.h" after removing these

When receive.denyCurrentBranch is set to updateInstead, a push that
tries to update the branch that is currently checked out is accepted
only when the index and the working tree exactly matches the
currently checked out commit, in which case the index and the
working tree are updated to match the pushed commit. Otherwise the
push is refused.
This hook can be used to customize this "push-to-deploy" logic. The
hook receives the commit with which the tip of the current branch is
going to be updated, and can decide what kind of local changes are
acceptable and how to update the index and the working tree to match
the updated tip of the current branch.
For example, the hook can simply run `git read-tree -u -m HEAD "$1"`
in order to emulate 'git fetch' that is run in the reverse direction
with `git push`, as the two-tree form of `read-tree -u -m` is
essentially the same as `git checkout` that switches branches while
keeping the local changes in the working tree that do not interfere
with the difference between the branches.
We have been silently tolerating errors by returning early with an
error that the caller ignores since rerere.autoupdate was introduced
in v1.6.0-rc0~120^2 (2008-06-22). So on error (for example if the
index is already locked), rerere can return success silently without
updating the index or with only some items in the index updated.
Better to treat such failures as a fatal error so the operator can
figure out what is wrong and fix it.

This adds support to send-pack to negotiate and use atomic pushes
iff the server supports it. Atomic pushes are activated by a new command
line flag --atomic.
In order to do this we also need to change the semantics for send_pack()
slightly. The existing send_pack() function actually doesn't send all the
refs back to the server when multiple refs are involved, for example
when using --all. Several of the failure modes for pushes can already be
detected locally in the send_pack client based on the information from the
initial server side list of all the refs as generated by receive-pack.
Any such refs that we thus know would fail to push are thus pruned from
the list of refs we send to the server to update.
For atomic pushes, we have to deal thus with both failures that are detected
locally as well as failures that are reported back from the server. In order
to do so we treat all local failures as push failures too.
We introduce a new status code REF_STATUS_ATOMIC_PUSH_FAILED so we can
flag all refs that we would normally have tried to push to the server
but we did not due to local failures. This is to improve the error message
back to the end user to flag that "these refs failed to update since the
atomic push operation failed."

remote-curl: fall back to Basic auth if Negotiate fails
Apache servers using mod_auth_kerb can be configured to allow the user
to authenticate either using Negotiate (using the Kerberos ticket) or
Basic authentication (using the Kerberos password). Often, one will
want to use Negotiate authentication if it is available, but fall back
to Basic authentication if the ticket is missing or expired.
However, libcurl will try very hard to use something other than Basic
auth, even over HTTPS. If Basic and something else are offered, libcurl
will never attempt to use Basic, even if the other option fails.
Teach the HTTP client code to stop trying authentication mechanisms that
don't use a password (currently Negotiate) after the first failure,
since if they failed the first time, they will never succeed.
