Roman Lebedev 728284dc39 [clang-tidy] FunctionSizeCheck: wrap FunctionASTVisitor into anon namespace, NFC
This check is relatively simple, and is often being used
as an example. I'm aware of at least two cases, when
simply copying the FunctionASTVisitor class to a new
check resulted in a rather unobvious segfault. Having it
in anonymous namespace prevents such a problem.

No functionality change, so i opted to avoid phabricator,
especially since clang-tidy reviews are seriously jammed.

Jonas Toth a735803801 [clang-tidy] add more aliases for the hicpp module
This patch will introduce even more aliases for the hicpp-module to already existing
checks and is a follow up for D30383 finishing the other sections.
It fixes a forgotten highlight in hicpp-braces-around-statements.rst, too.

Richard Smith 02c3baaad2 Fix ODR violations due to abuse of LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR
This is a short-term fix for PR33650 aimed to get the modules build bots green again.

Remove all the places where we use the LLVM_YAML_IS_(FLOW_)?SEQUENCE_VECTOR
macros to try to locally specialize a global template for a global type. That's
not how C++ works.

Instead, we now centrally define how to format vectors of fundamental types and
of string (std::string and StringRef). We use flow formatting for the former
cases, since that's the obvious right thing to do; in the latter case, it's
less clear what the right choice is, but flow formatting is really bad for some
cases (due to very long strings), so we pick block formatting. (Many of the
cases that were using flow formatting for strings are improved by this change.)

Other than the flow -> block formatting change for some vectors of strings,
this should result in no functionality change.

Yan Wang 36206206cd [clang-tidy][Part1] Add a new module Android and three new checks.
Summary:
A common source of security bugs is code that opens a file descriptors without using the O_CLOEXEC flag.  (Without that flag, an opened sensitive file would remain open across a fork+exec to a lower-privileged SELinux domain, leaking that sensitive data.).

Add a new Android module and one checks in clang-tidy.
-- open(), openat(), and open64() should include O_CLOEXEC in their flags argument. [android-file-open-flag]

Roman Lebedev eb6d821cda [clang-tidy] readability-function-size: fix nesting level calculation
Summary:
A followup for D32942.

Malcolm Parsons has provided a valid testcase that the initial version of the check complained about nested `if`'s.
As it turns out, the culprit is the **partially** un-intentional `switch` fallthrough.
So rewrite the NestingThreshold logic without ab-using+mis-using that switch with fallthrough, and add testcases with nested `if`' where there should be a warning and shouldn't be a warning. This results in a cleaner, simpler code, too.

I guess, now it would be actually possible to pick some reasonable default for `NestingThreshold` setting.

Fixes PR33454.

I was able to find only one coding style referencing nesting:
  - https://www.kernel.org/doc/html/v4.10/process/coding-style.html#indentation
     > In short, 8-char indents make things easier to read, and have the added benefit of warning you when you’re nesting your functions too deep.

This seems too basic, i'm not sure what else to test. Are more tests needed?

For some reason `findEndLocation` seems to skips too many (vertical) whitespaces in this case. The same problem already occured with string literals (https://reviews.llvm.org/D25558), and was fixed by adding a special check for this very case. I just extended the condition to also include char constants. No idea what really causes the issue though.

Jakub Kuderski f8d872c66e [clang-tidy] Fix PR32896: detect initializer lists in modernize-use-empalce
Summary:
This patch fixes [[ https://bugs.llvm.org/show_bug.cgi?id=32896 | PR32896 ]].

The problem was that modernize-use-emplace incorrectly removed changed push_back into emplace_back, removing explicit constructor call with initializer list parameter, resulting in compiler error after applying fixits.
modernize-use-emplace used to check if matched constructor had InitListExpr, but didn't check against CXXStdInitializerListExpr.

Eg.

```
std::vector<std::vector<int>> v;
  v.push_back(std::vector<int>({1})); // --> v.emplace_back({1});

Alexander Kornienko eec01adde3 [clang-tidy] Update IdentifierNamingCheck to remove extra leading/trailing underscores
Summary:
The goal of this change is to fix the following suboptimal replacements currently suggested by clang-tidy:
```
// with MemberPrefix == "_"
int __foo;  // accepted without complaint
```
```
// with MemberPrefix == "m_"
int _foo;
    ^~~~~~
    m__foo
```

I fixed this by
- updating `matchesStyle()` to reject names which have a leading underscore after a prefix has already been stripped, or a trailing underscore if a suffix has already been stripped;
- updating `fixupWithStyle()` to strip leading & trailing underscores before adding the user-defined prefix and suffix.

The replacements are now:
```
// MemberPrefix == "_"
int __foo;
    ^~~~~~
    _foo
```
```
// MemberPrefix == "m_"
int _foo;
    ^~~~~
    m_foo
```

Future improvements might elect to add .clang-tidy flags to improve what is being stripped. For instance, stripping `m_` could allow `m_foo` to be automatically replaced with `_foo`.

If there are errors running clang-apply-replacements, the script currently crashes or displays no error at all.

This patch checks for errors running clang-apply-replacements the same way clang-tidy binary is handled.

Another option would be probably checking for clang-apply-replacements (when -fix is passed) even before running clang-tidy.

The "performance-inefficient-vector-operation" check finds vector oprations in

This is the first version, only detects typical for-loop:

```
std::vector<int> v;
for (int i = 0; i < n; ++i) {
  v.push_back(i);
}

// or

for (int i = 0; i < v2.size(); ++i) {
  v.push_back(v2[i]);
}
```

We can extend it to handle more cases like for-range loop in the future.

Alexander Kornienko ee9247ed13 [clang-tidy] modified identifier naming case to use CT_AnyCase for ignoring case style
Summary:
Using CaseType::CT_AnyCase for selected identifier results in inheriting case style setting from more basic identifier type.

This patch changes CT_AnyCase behavior to ignore case style of specified identifier. If case style was not set, llvm::Optional will be used for keeping this information (llvm::Optional<>::hasVal), thus CT_AnyCase will no longer mean more general identifier style should be used.

This eliminates false-positives when naming convention is not clear for specific areas of code (legacy, third party) or for selected types.

Chandler Carruth 08781dc3b6 Don't make unqualified calls to functions that could well be found via
ADL as reasonable extension points.

All of this would be cleaner if this code followed the more usual LLVM
convention of not having deeply nested namespaces inside of .cpp files
and instead having a `using namespace ...;` at the top. Then the static
function would be in the global namespace and easily referred to as
`::join`. Instead we have to write a fairly contrived qualified name.
I figure the authors can clean this up with a less ambiguous name, using
the newly provided LLVM `join` function, or any other solution, but this
at least fixes the build.

Martin Bohme a6391ae52b [clang-tidy] misc-use-after-move: Fix failing assertion
Summary:
I've added a test case that (without the fix) triggers the assertion,
which happens when a move happens in an implicitly called conversion
operator.

The false positive happens on two neighbour CXXDefaultArgExpr AST nodes.
like below:

```
CXXFunctionalCastExpr 0x85c9670 <col:7, col:23> 'struct ZZ' functional cast to struct ZZ <ConstructorConversion>
 `-CXXConstructExpr 0x85c9518 <col:7, col:23> 'struct ZZ' 'void (uint64, const uint64 *)'
   |-CallExpr 0x85a0a90 <col:10, col:22> 'uint64':'unsigned long long'
   | |-ImplicitCastExpr 0x85a0a78 <col:10> 'uint64 (*)(uint64)' <FunctionToPointerDecay>
   | | `-DeclRefExpr 0x85a09f0 <col:10> 'uint64 (uint64)' lvalue Function 0x85a06a0 'Hash' 'uint64 (uint64)'
   | `-CXXDefaultArgExpr 0x85a0ac8 <<invalid sloc>> 'uint64':'unsigned long long'
   `-CXXDefaultArgExpr 0x85c94f8 <<invalid sloc>> 'const uint64 *'
```

For each particular CXXDefaultArgExpr node, we need to reset
FirstSubExpr, otherwise FirstSubExpr will refer to an incorrect expr.

The check doesn't really know if the code it is warning about came before

about code before the header guard. The location for the warning is still
not optimal, but I don't think fixing that is worth the effort, the
preprocessor doesn't give us a better location.

Alexander Kornienko ebdfb9cf0c [Clang-tidy] check for malloc, realloc and free calls
Summary:
This checker flags the use of C-style memory management functionality and notes about modern alternatives.
In an earlier revision it tried to autofix some kind of patterns, but that was a bad idea. Since memory management can be so widespread in a program, manual updating is most likely necessary.
Maybe for special cases, there could be later additions to this basic checker.

This is the first checker I wrote and I never did something with clang (only compiling programs). So whenever I missed conventions or did plain retarded stuff, feel free to point it out! I am willing to fix them and write a better checker.

I hope the patch does work, I never did this either. On a testapply in my repository it did, but I am pretty unconfident in my patching skills :)

```
// Style options: All identifiers should start with an upper case letter.
struct base { ...  }; 
struct der :  base {
  int field;  // FIXES: int Field;
  der() : der(42) {} // FIXES: Der() : Der(42) {}
  der(int X) : base(), field(X) {} // FIXES: Der(int X) : Base(), field(X)
  // Note that `field` doesn't get replaced
};

  void bar(int x, int y);

  namespace N {
    void bar(int x, int y);
  }

  void foo(){
    auto Test = std::bind(N::bar,1,1);
  }

clang-tidy’s modernize-avoid-bind check suggests writing:

  void foo(){
    auto Test =[] {return bar(1,1);};
  }

instead of:

  void foo(){
    auto Test = [] {return N::bar(1,1);};
  }

So clang-tidy has proposed an incorrect Fix.

Martin Bohme 934743f8f8 [clang-tidy] Add additional diagnostic to misc-use-after-move
Summary:
This adds a diagnostic to the misc-use-after-move check that is output when the
use happens on a later loop iteration than the move, for example:

    A a;
    for (int i = 0; i < 10; ++i) {
      a.foo();
      std::move(a);
    }

This situation can be confusing to users because, in terms of source code
location, the use is above the move. This can make it look as if the warning
is a false positive, particularly if the loop is long but the use and move are
close together.

In cases like these, misc-use-after-move will now output an additional
diagnostic:

  a.cpp:393:7: note: the use happens in a later loop iteration than the move
