Remove the redundant REG_NEWLINE regcomp() flag from the code that
compiles a fixed-string regular-expression.
The REG_NEWLINE causes metacharacters such as "." to match a newline,
since the basic_regex_quote_buf() function being called here escapes
all metacharacters using REG_NEWLINE is confusing and redundant.
The use of this flag was introduced as an unintended emergent property
of 793dc676e0 ("grep/icase: avoid kwsset when -F is specified",
2016-06-25).
That change amended the existing regflags, which were initialized to
REG_NEWLINE in init_grep_defaults() assuming a subsequent non-fixed
regcomp().
Manual testing reveals that this was always redundant, since no flags
of any use were inherited from opt->regflags even back
then. 793dc676e0 passes all tests with this on top:

if (opt->ignore_case)
Since this isn't used for anything and never was, remove it to reduce
confusion when reading this code.

Refactor calls to the grep machinery to always pass opt.ignore_case &
opt.extended_regexp_option instead of setting the equivalent regflags
bits.
The bug fixed when making -i work with -P in commit 9e3cbc59d5 ("log:
make --regexp-ignore-case work with --perl-regexp", 2017-05-20) was
really just plastering over the code smell which this change fixes.
The reason for adding the extensive commentary here is that I
discovered some subtle complexity in implementing this that really
should be called out explicitly to future readers.
Before this change we'd rely on the difference between
`extended_regexp_option` and `regflags` to serve as a membrane between
our preliminary parsing of grep.extendedRegexp and grep.patternType,
and what we decided to do internally.
Now that those two are the same thing, it's necessary to unset
`extended_regexp_option` just before we commit in cases where both of
those config variables are set. See 84befcd0a4 ("grep: add a
grep.patternType configuration setting", 2012-08-03) for the code and
documentation related to that.
The explanation of why the if/else branches in
grep_commit_pattern_type() are ordered the way they are exists in that
commit message, but I think it's worth calling this subtlety out
explicitly with a comment for future readers.
Even though grep_commit_pattern_type() is the only caller of
grep_set_pattern_type_option() it's simpler to reset the
extended_regexp_option flag in the latter, since 2/3 branches in the
former would otherwise need to reset it, this way we can do it in one
place.

Remove the redundant re-assignments of the fixed/pcre1/pcre2 fields to
zero right after the entire struct has been set to zero via
memset(...).
See an earlier related cleanup commit e0b9f8ae09 ("grep: remove
redundant regflags assignments", 2017-05-25) for an explanation of why
the code was structured like this to begin with.

Remove the redundant re-assignment of the fixed field to zero right
after the entire struct has been set to zero via memset(...).
Unlike some nearby commits this pattern doesn't date back to the
pattern described in e0b9f8ae09 ("grep: remove redundant regflags
assignments", 2017-05-25), instead it was apparently cargo-culted in
9eceddeec6 ("Use kwset in grep", 2011-08-21).

Adjust a now-redundant assignment to extended_regexp_option to make it
zero if grep.extendedRegexp is not set. This is always called right
after init_grep_defaults() which memsets the entire structure to 0, so
there's no need to set it again to zero.
However the reason for the if/else pattern is a holdover from[1] where
this was adjusted from a bitfield assignment to a boolean. Rather than
getting rid of the assignment to 0 in all cases, let's just use the
value returned by git_config_bool(), which is more idiomatic and in
sync with the rest of the boolean handling in this function.
This is a logical follow-up to my commit to remove redundant regflags
assignments[2]. This logic was originally introduced in [3], but as
explained in the former commit it's working around a pattern in our
code that no longer exists, and is now confusing as it leads the
reader to think that this needs to be flipped back & forth.

Stop assigning 0 to the extended_regexp_option field right after we've
zeroed out the entire struct with memset() just a few lines earlier.
Unlike some of the code being refactored in subsequent commits, this
was always completely redundant. See the original code introduced in
84befcd0a4 ("grep: add a grep.patternType configuration setting",
2012-08-03).

When help.autoCorrect is enabled, an invalid git command prints a
warning and a continuation message, which differs depending on
whether or not the value of help.autoCorrect is positive or
negative.

With help.autoCorrect < 0:

The continuation message's phrasing is awkward. This commit cleans it up.
As a bonus, we now use full-sentence strings which make translation easier.

"git add -p" were updated in 2.12 timeframe to cope with custom
core.commentchar but the implementation was buggy and a
metacharacter like $ and * did not work.

add--interactive: quote commentChar regex
add--interactive: handle EOF in prompt_yesno

Since c9d961647 (i18n: add--interactive: mark
edit_hunk_manually message for translation, 2016-12-14),
when the user asks to edit a hunk manually, we respect
core.commentChar in generating the edit instructions.
However, when we then strip out comment lines, we use a
simple regex like:
/^$commentChar/
If your chosen comment character is a regex metacharacter,
then that will behave in a confusing manner ("$", for
instance, would only eliminate blank lines, not actual
comment lines).
We can fix that by telling perl not to respect
metacharacters.

The prompt_yesno function loops indefinitely waiting for a
"y" or "n" response. But it doesn't handle EOF, meaning
that we can end up in an infinite loop of reading EOF from
stdin. One way to simulate that is with:
echo e | GIT_EDITOR='echo corrupt >' git add -p
Let's break out of the loop and propagate the undef to the
caller. Without modifying the callers that effectively turns
it into a "no" response. This is reasonable for both of the
current callers, and it leaves room for any future caller to
check for undef explicitly.

`for_each_bisect_ref()` is called by `for_each_bad_bisect_ref()` with
a term "bad". This used to make it call `for_each_ref_in_submodule()`
with a prefix "refs/bisect/bad". But the latter is the name of the
reference that is being sought, so the empty string was being passed
to the callback as the trimmed refname. Moreover, this questionable
practice was turned into an error by
b9c8e7f2fb prefix_ref_iterator: don't trim too much, 2017-05-22
It makes more sense (and agrees better with the documentation of
`--bisect`) for the callers to receive the full reference names. So
* Add a new function, `for_each_fullref_in_submodule()`, to the refs
API. This plugs a gap in the existing functionality, analogous to
`for_each_fullref_in()` but accepting a `submodule` argument.
* Change `for_each_bad_bisect_ref()` to call the new function rather
than `for_each_ref_in_submodule()`.
* Add a test.

Commit 28ed9830b1 (get_packed_ref_cache(): assume "packed-refs" won't
change while locked, 2017-05-22) assumes that the "packed-refs" file
cannot change while we hold the lock. That assumption is
justified *if* the lock has been held the whole time since the
"packed-refs" file was last read.
But in `lock_packed_refs()`, we ourselves lock the "packed-refs" file
and then call `get_packed_ref_cache()` to ensure that the cache agrees
with the file. The intent is to guard against the possibility that
another process changed the "packed-refs" file the moment before we
locked it.
This check was defeated because `get_packed_ref_cache()` saw that the
file was locked, and therefore didn't do the `stat_validity_check()`
that we want.
The mistake was compounded with a misleading comment in
`lock_packed_refs()` claiming that it was doing the right thing. That
comment came from an earlier draft of the mh/packed-ref-store-prep
patch series when the commits were in a different order.
So instead:
* Extract a function `validate_packed_ref_cache()` that does the
validity check independent of whether the lock is held.
* Change `get_packed_ref_cache()` to call the new function, but only
if the lock *isn't* held.
* Change `lock_packed_refs()` to call the new function in any case
before calling `get_packed_ref_cache()`.
* Fix the comment in `lock_packed_refs()`.

$commit1:$path $commit2:$path", used to be shown with the full
object name as given on the command line, but it is more natural to
use the $path in the output and use it to look up .gitattributes.
* jk/diff-blob:
diff: use blob path for blob/file diffs
diff: use pending "path" if it is available
diff: use the word "path" instead of "name" for blobs
diff: pass whole pending entry in blobinfo
handle_revision_arg: record paths for pending objects
handle_revision_arg: record modes for "a..b" endpoints
t4063: add tests of direct blob diffs
get_sha1_with_context: dynamically allocate oc->path
get_sha1_with_context: always initialize oc->symlink_path
sha1_name: consistently refer to object_context as "oc"
handle_revision_arg: add handle_dotdot() helper
handle_revision_arg: hoist ".." check out of range parsing
handle_revision_arg: stop using "dotdot" as a generic pointer
handle_revision_arg: simplify commit reference lookups
handle_revision_arg: reset "dotdot" consistently

"git describe --contains" penalized light-weight tags so much that
they were almost never considered. Instead, give them about the
same chance to be considered as an annotated tag that is the same

A common pattern to free a piece of memory and assign NULL to the
pointer that used to point at it has been replaced with a new
FREE_AND_NULL() macro.
* ab/free-and-null:
*.[ch] refactoring: make use of the FREE_AND_NULL() macro
coccinelle: make use of the "expression" FREE_AND_NULL() rule
coccinelle: add a rule to make "expression" code use FREE_AND_NULL()

Replace occurrences of `free(ptr); ptr = NULL` which weren't caught by
the coccinelle rule. These fall into two categories:
- free/NULL assignments one after the other which coccinelle all put
on one line, which is functionally equivalent code, but very ugly.
- manually spotted occurrences where the NULL assignment isn't right
after the free() call.

Add a FREE_AND_NULL() wrapper marco for the common pattern of freeing
a pointer and assigning NULL to it right afterwards.
The implementation is similar to the (currently unused) XDL_PTRFREE
macro in xdiff/xmacros.h added in commit 3443546f6e ("Use a *real*
built-in diff generator", 2006-03-24). The only difference is that
free() is called unconditionally, see [1].
See [2] for a suggested alternative which does this via a function
instead of a macro. As covered in replies to that message, while it's
a viable approach, it would introduce caveats which this approach
doesn't have, so that potential change is left to a future follow-up
change.
This merely allows us to translate exactly what we're doing now to a
less verbose & idiomatic form using a macro, while guaranteeing that
we don't introduce any functional changes.

Using "git add d/i/r" when d/i/r is the top of the working tree of
a separate repository would create a gitlink in the index, which
would appear as a not-quite-initialized submodule to others. We
learned to give warnings when this happens.

Some submodule tests do some setup outside of a test_expect
block. This is bad because we won't actually check the
outcome of those commands. But it's doubly so because "git
add submodule" now produces a warning to stderr, which is
not suppressed by the test scripts in non-verbose mode.
This patch does the minimal to fix the annoying warnings.
All three of these scripts could use more cleanup of related
setup.

It's an easy mistake to add a repository inside another
repository, like:
git clone $url
git add .
The resulting entry is a gitlink, but there's no matching
.gitmodules entry. Trying to use "submodule init" (or clone
with --recursive) doesn't do anything useful. Prior to
v2.13, such an entry caused git-submodule to barf entirely.
In v2.13, the entry is considered "inactive" and quietly
ignored. Either way, no clone of your repository can do
anything useful with the gitlink without the user manually
adding the submodule config.
In most cases, the user probably meant to either add a real
submodule, or they forgot to put the embedded repository in
their .gitignore file.
Let's issue a warning when we see this case. There are a few
things to note:
- the warning will go in the git-add porcelain; anybody
wanting to do low-level manipulation of the index is
welcome to create whatever funny states they want.
- we detect the case by looking for a newly added gitlink;
updates via "git add submodule" are perfectly reasonable,
and this avoids us having to investigate .gitmodules
entirely
- there's a command-line option to suppress the warning.
This is needed for git-submodule itself (which adds the
entry before adding any submodule config), but also
provides a mechanism for other scripts doing
submodule-like things.
We could make this a hard error instead of a warning.
However, we do add lots of sub-repos in our test suite. It's
not _wrong_ to do so. It just creates a state where users
may be surprised. Pointing them in the right direction with
a gentle hint is probably the best option.
There is a config knob that can disable the (long) hint. But
I intentionally omitted a config knob to disable the warning
entirely. Whether the warning is sensible or not is
generally about context, not about the user's preferences.
If there's a tool or workflow that adds gitlinks without
matching .gitmodules, it should probably be taught about the
new command-line option, rather than blanket-disabling the
warning.

'git_config_with_options()' takes a 'config_options' struct which
contains feilds for 'git_dir' and 'commondir'. If those feilds happen
to be NULL the config machinery falls back to querying global repository
state. Let's change this and instead use these fields in the
'config_options' struct explicilty all the time. Since the API is
slightly changing to require these two fields to be set if callers want
the config machinery to load the repository's config, let's change the
name to 'config_with_optison()'. This allows the config machinery to
not implicitly rely on any global repository state.
