real_pathdup(): fix callsites that wanted it to die on error
In 4ac9006f832 (real_path: have callers use real_pathdup and
strbuf_realpath, 2016-12-12), we changed the xstrdup(real_path())
pattern to use real_pathdup() directly.
The problem with this change is that real_path() calls
strbuf_realpath() with die_on_error = 1 while real_pathdup() calls
it with die_on_error = 0. Meaning that in cases where real_path()
causes Git to die() with an error message, real_pathdup() is silent
and returns NULL instead.
The callers, however, are ill-prepared for that change, as they expect
the return value to be non-NULL (and otherwise the function died
with an appropriate error message).
Fix this by extending real_pathdup()'s signature to accept the
die_on_error flag and simply pass it through to strbuf_realpath(),
and then adjust all callers after a careful audit whether they would
handle NULLs well.

The ewah subsystem typedefs eword_t to be uint64_t, but some
code uses a bare uint64_t. This isn't a bug now, but it's a
potential maintenance problem if the definition of eword_t
ever changes. Let's use the correct type.
Note that we can't use COPY_ARRAY() here because the source
and destination point to objects of different sizes. For
that reason we'll also skip the usual "sizeof(*dst)" and use
the real type, which should make it more clear that there's
something tricky going on.

This memcpy meant to get the sizeof a "struct range", not a
"range_set", as the former is what our array holds. Rather
than swap out the types, let's convert this site to
COPY_ARRAY, which avoids the problem entirely (and confirms
that the src and dst types match).
Note for curiosity's sake that this bug doesn't trigger on
I32LP64 systems, but does on ILP32 systems. The mistaken
"struct range_set" has two ints and a pointer. That's 16
bytes on LP64, or 12 on ILP32. The correct "struct range"
type has two longs, which is also 16 on LP64, but only 8 on
ILP32.
Likewise an IL32P64 system would experience the bug.

line-log.c: prevent crash during union of too many ranges
The existing implementation of range_set_union does not correctly
reallocate memory, leading to a heap overflow when it attempts to union
more than 24 separate line ranges.
For struct range_set *out to grow correctly it must have out->nr set to
the current size of the buffer when it is passed to range_set_grow.
However, the existing implementation of range_set_union only updates
out->nr at the end of the function, meaning that it is always zero
before this. This results in range_set_grow never growing the buffer, as
well as some of the union logic itself being incorrect as !out->nr is
always true.
The reason why 24 is the limit is that the first allocation of size 1
ends up allocating a buffer of size 24 (due to the call to alloc_nr in
ALLOC_GROW). This goes some way to explain why this hasn't been
caught before.
Fix the problem by correctly updating out->nr after reallocating the
range_set. As this results in out->nr containing the same value as the
variable o, replace o with out->nr as well.
Finally, add a new test to help prevent the problem reoccurring in the
future. Thanks to Vegard Nossum for writing the test.

diff: do not short-cut CHECK_SIZE_ONLY check in diff_populate_filespec()
Callers of diff_populate_filespec() can choose to ask only for the
size of the blob without grabbing the blob data, and the function,
after running lstat() when the filespec points at a working tree
file, returns by copying the value in size field of the stat
structure into the size field of the filespec when this is the case.
However, this short-cut cannot be taken if the contents from the
path needs to go through convert_to_git(), whose resulting real blob
data may be different from what is in the working tree file.
As "git diff --quiet" compares the .size fields of filespec
structures to skip content comparison, this bug manifests as a
false "there are differences" for a file that needs eol conversion,
for example.

add--interactive: fix missing file prompt for patch mode with "-i"
When invoked as "git add -i", each menu interactive menu
option prompts the user to select a list of files. This
includes the "patch" option, which gets the list before
starting the hunk-selection loop.
As "git add -p", it behaves differently, and jumps straight
to the hunk selection loop.
Since 0539d5e6d (i18n: add--interactive: mark patch prompt
for translation, 2016-12-14), the "add -i" case mistakenly
jumps to straight to the hunk-selection loop. Prior to that
commit the distinction between the two cases was managed by
the $patch_mode variable. That commit used $patch_mode for
something else, and moved the old meaning to the "$cmd"
variable. But it forgot to update the $patch_mode check
inside patch_update_cmd() which controls the file-list
behavior.
The simplest fix would be to change that line to check $cmd.
But while we're here, let's use a less obscure name for this
flag: $patch_mode_only, a boolean which tells whether we are
in full-interactive mode or only in patch-mode.

submodule init: warn about falling back to a local path
When a submodule is initialized, the config variable 'submodule.<name>.url'
is set depending on the value of the same variable in the .gitmodules
file. When the URL indicates to be relative, then the url is computed
relative to its default remote. The default remote cannot be determined
accurately in all cases, such that it falls back to 'origin'.
The 'origin' remote may not exist, though. In that case we give up looking
for a suitable remote and we'll just assume it to be a local relative path.
This can be confusing to users as there is a lot of guessing involved,
which is not obvious to the user.
So in the corner case of assuming a local autoritative truth, warn the
user to lessen the confusion.
This behavior was introduced in 4d6893200 (submodule add: allow relative
repository path even when no url is set, 2011-06-06), which shared the
code with submodule-init and then ported to C in 3604242f080a (submodule:
port init from shell to C, 2016-04-15).
In case of submodule-add, this behavior makes sense in some use cases[1],
however for submodule-init there does not seem to be an immediate obvious
use case to fall back to a local submodule. However there might be, so
warn instead of die here.
While adding the warning, also clarify the behavior of relative URLs in
the documentation.

(that is to say, as long as the Git part of the path and the query
string is preserved in the final redirect destination, the intermediate
steps can have any URL). However, if one of the intermediate steps
results in an HTTP exception, a confusing "unable to update url base
from redirection" message is printed instead of a Curl error message
with the HTTP exception code.
This was introduced by 2 commits. Commit c93c92f ("http: update base
URLs when we see redirects", 2013-09-28) introduced a best-effort
optimization that required checking if only the "base" part of the URL
differed between the initial request and the final redirect destination,
but it performed the check before any HTTP status checking was done. If
something went wrong, the normal code path was still followed, so this
did not cause any confusing error messages until commit 6628eb4 ("http:
always update the base URL for redirects", 2016-12-06), which taught
http to die if the non-"base" part of the URL differed.
Therefore, teach http to check the HTTP status before attempting to
check if only the "base" part of the URL differed. This commit teaches
http_request_reauth to return early without updating options->base_url
upon an error; the only invoker of this function that passes a non-NULL
"options" is remote-curl.c (through "http_get_strbuf"), which only uses
options->base_url for an informational message in the situations that
this commit cares about (that is, when the return value is not HTTP_OK).
The included test checks that the redirect scheme at the beginning of
this commit message works, and that returning a 502 in the middle of the
redirect scheme produces the correct result. Note that this is different
from the test in commit 6628eb4 ("http: always update the base URL for
redirects", 2016-12-06) in that this commit tests that a Git-shaped URL
(http://.../info/refs?service=git-upload-pack) works, whereas commit 6628eb4 tests that a non-Git-shaped URL
(http://.../info/refs/foo?service=git-upload-pack) does not work (even
though Git is processing that URL) and is an error that is fatal, not
silently swallowed.

docs/diffcore: unquote "Complete Rewrites" in headers
The gitdiffcore documentation quotes the term "Complete Rewrites" in
headers for no real gain. This would make sense if the term could be
easily confused if not properly grouped together. But actually, the term
is quite obvious and thus does not really need any quoting, especially
regarding that it is not used anywhere else.
But more importanly, this brings up a bug when rendering man pages: when
trying to render quotes inside of a section header, we end up with
quotes which have been misaligned to the end of line. E.g.
diffcore-break: For Splitting Up Complete Rewrites
--------------------------------------------------
renders as
DIFFCORE-BREAK: FOR SPLITTING UP COMPLETE REWRITES""
, which is obviously wrong. While this is fixable for the man pages by
using double-quotes (e.g. ""COMPLETE REWRITES""), this again breaks it
for our generated HTML pages.
So fix the issue by simply dropping quotes inside of section headers,
which is currently only done for the term "Complete Rewrites".

When "git merge" detects a path that is renamed in one history
while the other history deleted (or modified) it, it now reports
both paths to help the user understand what is going on in the two
histories being merged.

merge-recursive: make "CONFLICT (rename/delete)" message show both paths
Deletion of a branch "foo/bar" could remove .git/refs/heads/foo
once there no longer is any other branch whose name begins with
"foo/", but we didn't do so so far. Now we do.

In one test, we use "git checkout --orphan HEAD" to create
an unborn branch. Confusingly, the resulting branch is named
"refs/heads/HEAD". The original probably meant something
like:
git checkout --orphan orphaned-branch HEAD
Let's just use "orphaned-branch" here to make this less
confusing. Putting HEAD in the second argument is already
implied.

commit: don't check for space twice when looking for header
Both standard_header_field() and excluded_header_field() check if
there's a space after the buffer that's handed to them. We already
check in the caller if that space is present. Don't bother calling
the functions if it's missing, as they are guaranteed to return 0 in
that case, and remove the now redundant checks from them.

commit: be more precise when searching for headers
Search for a space character only within the current line in
read_commit_extra_header_lines() instead of searching in the whole
buffer (and possibly beyond, if it's not NUL-terminated) and then
discarding any results after the end of the current line.

Add a function for appending the canonized absolute pathname of a given
path to a strbuf. It keeps the existing contents intact, as expected of
a function of the strbuf_add() family, while avoiding copying the result
if the given strbuf is empty. It's more consistent with the rest of the
strbuf API than strbuf_realpath(), which it's wrapping.
Also add a semantic patch demonstrating its intended usage and apply it
to the current tree. Using strbuf_add_real_path() instead of calling
strbuf_addstr() and real_path() avoids an extra copy to a static buffer.

sha1_file: release fallback base's memory in unpack_entry()
If a pack entry that's used as a delta base is corrupt, unpack_entry()
marks it as unusable and then searches the object again in the hope that
it can be found in another pack or in a loose file. The memory for this
external base object is never released. Free it after use.

This variable needs to be specified to make some types of
non-basic authentication work, but ideally this would just
work out of the box for everyone.
However, simply setting it to "1" by default introduces an
extra round-trip for cases where it _isn't_ useful. We end
up sending a bogus empty credential that the server rejects.
Instead, let's introduce an automatic mode, that works like
this:
1. We won't try to send the bogus credential on the first
request. We'll wait to get an HTTP 401, as usual.
2. After seeing an HTTP 401, the empty-auth hack will kick
in only when we know there is an auth method available
that might make use of it (i.e., something besides
"Basic" or "Digest").
That should make it work out of the box, without incurring
any extra round-trips for people hitting Basic-only servers.
This _does_ incur an extra round-trip if you really want to
use "Basic" but your server advertises other methods (the
emptyauth hack will kick in but fail, and then Git will
actually ask for a password).
The auto mode may incur an extra round-trip over setting
http.emptyauth=true, because part of the emptyauth hack is
to feed this blank password to curl even before we've made a
single request.

Adding comments after a tag in the body is a common practise (e.g. in
the Linux kernel) and git-send-email has been supporting this for years
by removing any trailing cruft after the address.
After some recent changes, any trailing comment is now instead appended
to the recipient name (with some random white space inserted) resulting
in undesirable noise in the headers, for example:
CC: "# 3 . 3 . x : 1b9508f : sched : Rate-limit newidle" <stable@vger.kernel.org>
Revert to the earlier behaviour of discarding anything after the (first)
address in a tag while parsing the body.
Note that multiple addresses after are still allowed after a command
line switch (and in a CC header field).
Also note that --suppress-cc=self was never honoured when using multiple
addresses in a tag.

The parse_config_key() function was introduced to make it
easier to match "section.subsection.key" variables. It also
handles the simpler "section.key", and the caller is
responsible for distinguishing the two from its
out-parameters.
Most callers who _only_ want "section.key" would just use a
strcmp(var, "section.key"), since there is no parsing
required. However, they may still use parse_config_key() if
their "section" variable isn't a constant (an example of
this is in parse_hide_refs_config).
Using the parse_config_key is a bit clunky, though:
const char *subsection;
int subsection_len;
const char *key;
parse_config_key: use skip_prefix instead of starts_with
This saves us having to repeatedly add in "section_len" (and
also avoids walking over the first part of the string
multiple times for a strlen() and strrchr()).

refs: parse_hide_refs_config to use parse_config_key
parse_config_key was introduced in 1b86bbb0ade (config: add helper
function for parsing key names, 2013-01-22), the NEEDSWORK that is removed
in this patch was introduced at daebaa7813 (upload/receive-pack: allow
hiding ref hierarchies, 2013-01-18), which is only a couple days apart,
so presumably the code replaced in this patch was only introduced due
to not wanting to wait on the proper helper function being available.
Make the condition easier to read by using parse_config_key.
