Alexander Kornienko c0308c451b [clang-tidy] modernize-use-auto: don't remove stars by default
Summary:
By default, modernize-use-auto check will retain stars when replacing an explicit type with `auto`: `MyType *t = new MyType;` will be changed to `auto *t = new MyType;`, thus resulting in more consistency with the recommendations to use `auto *` for iterating over pointers in range-based for loops: http://llvm.org/docs/CodingStandards.html#beware-unnecessary-copies-with-auto

The new  `RemoveStars` option allows to revert to the old behavior: with the new option turned on the check will change `MyType *t = new MyType;` to `auto t = new MyType;`.

Benjamin Kramer b53452b2b1 [include-fixer] Be smarter about inserting symbols for a prefix.
If prefix search finds something where nothing can be nested under (e.g.
a variable or macro) don't add it to the result.

This is for cases like:
header.h:
  extern int a;

file.cc:
namespace a {
  SOME_MACRO
}

We will look up a::SOME_MACRO, which doesn't have any results. Then we
look up 'a' and find something before we ever look up just 'SOME_MACRO'.
With some basic filtering we can avoid this case.

Benjamin Kramer 5e6b35f4d1 [include-fixer] Also look up prefixes of queries.
This is used to find nested classes. For a nested name foo::bar::qux we
will first look up foo::bar::qux, then foo::bar, then foo unless we find
a result. This is used to support nested classes which are not part of
the index but can only be used if the header for the parent context is
included.

Samuel Benzaquen 4e05b82cc4 [clang-tidy] Speedup misc-static-assert.
Summary:
Speedup the misc-static-assert check by not use `stmt()` as the toplevel matcher.
The framework runs a filter on the matchers before trying them on each node and
uses the toplevel type for this.
Using `stmt()` as the toplevel causes the matcher to be run on every `Stmt` node,
even if the node doesn't match the desired types.

This change speeds up clang-tidy by ~5% in a benchmark.

Etienne Bergeron bda187decd [clang-tidy] New checker for redundant expressions.
Summary:
This checker finds redundant expression on both side of a binary operator.

The current implementation provide a function to check whether expressions
are equivalent. This implementation is able to recognize the common
subset encounter in C++ program. Side-effects like "x++" are not considered
to be equivalent.

There are many False Positives related to macros and to floating point
computations (detecting NaN). The checker is ignoring these cases.

Example:
```
    if( !dst || dst->depth != desired_depth ||
        dst->nChannels != desired_num_channels ||
        dst_size.width != src_size.width ||
        dst_size.height != dst_size.height )    <<--- bug

3) Added matching of macro wrapper used with clang on linux.

Etienne Bergeron bae829ede5 [clang-tidy] Add new checker for comparison with runtime string functions.
Summary:
This checker is validating suspicious usage of string compare functions.

Example:
```
  if (strcmp(...))       // Implicitly compare to zero
  if (!strcmp(...))      // Won't warn
  if (strcmp(...) != 0)  // Won't warn
```

This patch was checked over large amount of code.
There is three checks:
  [*] Implicit comparator to zero (coding-style, many warnings found),
  [*] Suspicious implicit cast to non-integral (bugs!?, almost none found),
  [*] Comparison to suspicious constant (bugs!?, found two cases),

Example:
[[https://github.com/kylepjohnson/sigma/blob/master/sigma/native-installers/debian/dependencies/files/opt/sigma/E/HEURISTICS/che_to_precgen.c |
https://github.com/kylepjohnson/sigma/blob/master/sigma/native-installers/debian/dependencies/files/opt/sigma/E/HEURISTICS/che_to_precgen.c]]

```
      else if(strcmp(id, "select") == 0)
      {
         array->array[i].key1 = 25;
      }
      else if(strcmp(id, "sk") == 28)      // BUG!?
      {
         array->array[i].key1 = 20;
      }
```

Alexander Kornienko bfb43b7298 [Clang-tidy] Fix for crash in modernize-raw-string-literal check
Summary:
Clang-tidy modernize-raw-string-literal check crashes on run-time assert while it is evaluating compiler predefined identifiers such as
- __FUNCTION__
- __func__
- __PRETTY_FUNCTION__

Check is asserting because it cannot find opening quote for such string literal. It occurs only on debug build config.
I think that it would be good to prune such cases by crossing off predefined expressions - there is no need to evaluate such matches.

Benjamin Kramer 6b23626192 [include-fixer] Add a prototype for a new include fixing tool.
Summary:
The goal of this tool is fairly simple, look up unknown identifiers in a
global database and add the corresponding #include line. It accomplishes
this by hooking into Sema as an ExternalSemaSource and responding to typo
correction callbacks. This means we can see the unknown identifier before
it's being munged by error recovery.

This doesn't work perfectly yet as some typo corrections don't emit
callbacks (delayed typos), but I think this is fixable. We also handle
only one include at a time as this is meant to be run directly from
the editing environment eventually. Adding multiple includes at the same
time is tricky because of error recovery.

This version only has a a dummy database, so all you can do is fixing
missing includes of <string>, but the indexer to build a database will
follow soon.

Etienne Bergeron 9cfd8cea6b [clang-tidy] Add more detection rules for redundant c_str calls.
Summary:
The string class contains methods which support receiving either a string literal or a string object.

For example, calls to append can receive either a char* or a string.
```
  string& append (const string& str);
  string& append (const char* s);
```

Which make these cases equivalent, and the .c_str() useless:
```
  std::string s = "123";
  str.append(s);
  str.append(s.c_str());
```

In these cases, removing .c_str()  doesn't provide any size or speed improvement.
It's only a readability issue.

If the string contains embedded NUL characters,  the string literal and the string
object won't produce the same semantic.

Etienne Bergeron 1f696b316c [clang-tidy] Add new checker for suspicious sizeof expressions
Summary:
This check is finding suspicious cases of sizeof expression.

Sizeof expression is returning the size (in bytes) of a type or an
expression. Programmers often abuse or misuse this expression.

This checker is adding common set of patterns to detect some
of these bad constructs.


Some examples found by this checker:

R/packages/ifultools/ifultools/src/fra_neig.c
```
        /* free buffer memory */
        (void) mutil_free( dist_buff, sizeof( ctr * sizeof( double ) ) );
        (void) mutil_free( nidx_buff, sizeof( ctr * sizeof( sint32 ) ) );
```


graphviz/v2_20_2/lib/common/utils.c
```
static Dtdisc_t mapDisc = {
    offsetof(item, p),
    sizeof(2 * sizeof(void *)),
    offsetof(item, link),
    (Dtmake_f) newItem,
    (Dtfree_f) freeItem,
    (Dtcompar_f) cmpItem,
    NIL(Dthash_f),
    NIL(Dtmemory_f),
    NIL(Dtevent_f)
};
```


mDNSResponder/mDNSShared/dnsextd.c
```
	context = ( TCPContext* ) malloc( sizeof( TCPContext ) );
	require_action( context, exit, err = mStatus_NoMemoryErr; LogErr( "AcceptTCPConnection", "malloc" ) );
	mDNSPlatformMemZero( context, sizeof( sizeof( TCPContext ) ) );
	context->d		 = self;

Summary:
In Release mode, the check was infinite looping over chromium code base.

It seems there is something strange with the creation of the Maps.
I believe the compiler is making some assumption with the implicit conversion from enum <-> int.

By moving the map to a standard switch/cases, we no longer allocate memory and we can keep the same behavior. For a small amount of elements, this is fine.

Gabor Horvath 5273f615c4 [clang-tidy] Extension of checker misc-misplaced-widening-cast
Summary:
Existing checker misc-misplaced-widening-cast was extended:
- New use cases: casted expression as lhs or rhs of a logical comparison or function argument
- New types: beside int, long and long long various char types, short and int128 added
- New option to check implicit casts: forgetting a cast is at least as common and as dangerous as misplacing it. This option can be disabled.

This patch depends on AST Matcher patches D17986 and D18243 and also contains fix for checker misc-bool-pointer-implicit-conversion needed because of the fix in the AST Matcher patch.

Etienne Bergeron 1eec3f01f0 [clang-tidy] Reduce false-positive ratio in misc-suspicious-missing-comma check.
Summary:
This patch is adding detection of common string literal patterns
that should not trigger warnings.

  [*] Add a limit on the number of concatenated token,
  [*] Add support for parenthese sequence of tokens,
  [*] Add detection of valid indentation.

As an example, this code will no longer trigger a warning:
```
const char* Array[] = {
  "first literal"
    "indented literal"
    "indented literal",
  "second literal",
  [...]
```

Alexander Kornienko 09464e63d8 [clang-tidy] fix a couple of modernize-use-override bugs
Fix for __declspec attributes and const=0 without space

This patch is to address 2 problems I found with Clang-tidy:modernize-use-override.

1: missing spaces on pure function decls.

Orig:
void pure() const=0
Problem:
void pure() constoverride =0
Fixed:
void pure() const override =0

2: This is ms-extension specific, but possibly applies to other attribute types. The override is placed before the attribute which doesn’t work well with declspec as this attribute can be inherited or placed before the method identifier.

Orig:
class __declspec(dllexport) X : public Y

{
void p();
};
Problem:
class override __declspec(dllexport) class X : public Y

{
void p();
};
Fixed:
class __declspec(dllexport) class X : public Y

{
void p() override;
};

Etienne Bergeron 3e4adf1762 [clang-tidy] Add a new checker to detect missing comma in initializer list.
Summary:
This checker is able to detect missing comma in 
an array of string literals.

```
  const char* A[] = {
    "abc",
    "def"   // missing comma (no compiler warnings)
    "ghi",
  };
```

The ratio of false-positive is reduced by restricting the
size of the array considered and the ratio of missing
comma.

To validate the quantity of false positive, the checker
was tried over LLVM and chromium code and detected these
cases:
