[PATCH] D30610: [clang-tidy] Added options to cppcoreguidelines-special-member-functions check
fgross created this revision.
Herald added subscribers: JDevlieghere, nemanjai.
Added two options to cppcoreguidelines-special-member-functions to allow a more
relaxed checking.
With 'AllowSoleDefaultDtor' set to 1, classes with explicitly defaulted
destructors but no other special members are not flagged anymore:
class foo {
// typical scenario: defaulted virtual destructor in base classes
virtual ~foo() = default;
};
With 'AllowMissingMoveFunctions' set to 1, classes with no move functions at
all are not flagged anymore:
class bar{
~bar();
bar(const bar&);
bar& operator=(const bar&);
};

+Options
+---
+
+.. option:: AllowSoleDefaultDtor
+
+ When set to `1` (default is `0`), this check doesn't flag classes with a sole, explicitly
+ defaulted destructor. An example for such a class is:
+
+ .. code-block:: c++
+
+ struct A {
+ virtual ~A() = default;
+ };
+
+.. option:: AllowMissingMoveFunctions
+
+ When set to `1` (default is `0`), this check doesn't flag classes which define no move
+ operations at all. It still flags classes which define only one of either
+ move constructor or move assignment operator. With this option enabled, the following class won't be flagged:
+
+ .. code-block:: c++
+
+ struct A {
+ A(const A&);

[PATCH] D30841: [clang-tidy] readability-misleading-indentation: fix chained if
fgross updated this revision to Diff 91473.
fgross added a comment.
Replaced std::map with llvm::DenseMap, added comment about traversal.
I just assumed it would traverse in the "right" way, is there any documentation
about AST / matcher traversal?

Now using `ASTContext::getParents` instead of `ChainedIfs` map.
For some reason I thought of `getParents` as an expensive function to call...

[PATCH] D61209: Fix readability-redundant-smartptr-get for MSVC STL
fgross created this revision.
fgross added reviewers: aaron.ballman, alexfh, sbenza.
Herald added a project: clang.
Herald added a subscriber: cfe-commits.
The MSVC STL defines smart pointer `operator*` and `operator->` as method
templates. The existing duck typing implementation doesn't catch this
implementation. To keep the duck typing simple, I added the already existing
list of known standard to the matchers in `registerMatchersForGetArrowStart`.

[PATCH] D33354: [clang-tidy] readability-braces-around-statements false positive with char literals
fgross created this revision.
Herald added a subscriber: xazax.hun.
Single-line if statements cause a false positive when the last token in the
conditional statement is a char constant:
if (condition)
return 'a';
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.

[PATCH] D33354: [clang-tidy] readability-braces-around-statements false positive with char literals
fgross updated this revision to Diff 99576.
fgross added a comment.
After some digging into it, here is my uneducated guess:
The comment in `findEndLocation` states that //"Loc points to the beginning of
the last token before ';'"//. But `checkStmt` calls it with
`FileRange.getEnd().getLocWithOffset(-1)`
so in fact it points to the last char of the last token. For a string literal
this would be '"' or ''', not enough for `Lexer::getLocForEndOfToken` to query
the correct token type. It ends up moving behind the following ';' and skipping
all whitespaces to next token.
I've updated the diff, this seems to resolve the issue. But I'm sure there is a
way to pass the correct location in the first place.

[PATCH] D36308: Add handling for DeducedType to HasDeclarationMatcher
fgross created this revision.
HasDeclarationMatcher did not handle DeducedType, it always returned false for
deduced types.
So with code like this:
struct X{};
auto x = X{};
This did no longer match:
varDecl(hasType(recordDecl(hasName("X"
Because HasDeclarationMatcher didn't resolve the DeducedType of `x`.
This came up because some checks in clang-tidy didn't match as expected anymore.

The scenario I had in mind was legacy code which was written back when it still
was the "rule of three" instead of the "rule of five". Those classes with
defined destructor and copy operations are still perfectly safe, because moving
them falls back to copying. They may not be perfectly tuned for performance,
but having no move operations is not an indication for some resoure management
error. That's why I do think this options makes sense.

>
My 2 cents on this one: Even with `AllowMissingMoveFunctions=1` at least the
missing destructor definition should be diagnosed, because it violates the
classic rule of three. If you delete your copy operations, you likely have some
resources that need to be taken care of in your destructor, so this piece of
code would worry me. Better be clear about it and explicitly default the
destructor.
