Krasimir Georgiev e6035a51f7 [clangd] Add parameter and return type information to completion results
Summary:
This patch adds information about the parameters and return types of completion
candidates.
Previously, for the following code:
```
struct S {
  int func(int a, double b) const;
};
```
the completer would only return the label of the candidate `func`.
Now it will also return the return type `int` and will format the label for the
candidate as `func(int a, double b) const`.

Alexander Kornienko 08936e4740 [clang-tidy] New checker to replace dynamic exception specifications
Summary:
New checker to replace dynamic exception
specifications

This is an alternative to D18575 which relied on reparsing the decl to
find the location of dynamic exception specifications, but couldn't
deal with preprocessor conditionals correctly without reparsing the
entire file.

This approach uses D20428 to find dynamic exception specification
locations and handles all cases correctly.

With the change https://reviews.llvm.org/D33013 driver will not build
compilation object if command line is invalid, in particular, if
unrecognized option is provided. In such cases it will prints diagnostics
on stderr. The test 'clang-tidy/diagnostic.cpp' checks reaction on
unrecognized option and will fail when D33013 is applied because it checks
only stdout for test patterns and expects the name of diagnostic category
prepared by clang-tidy. With this change the test makes more general check
and must work in either case.

Alexander Kornienko a0ddf5fc1c [clang-tidy] readability-braces-around-statements false positive with char literals
Summary:
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.

Alexander Kornienko 6180337fe1 [clang-tidy] Optimize GlobList::contains
With large lists of checks and large number of warnings GlobList::contains
starts being ridiculously CPU hungry, since it runs regexp match per glob.
Caching results of glob matching in a StringMap significantly speeds up check
filtering even for small GlobLists.

/tmp/q.cc:

void f() {
  int I;
  {int I;}
  {int I;}
  {int I;}
  ... // 200k times
}

Summary:
A refactoring to decouple ProtocolHandlers and Language Server input parsing
loop from the ClangdLSPServer.
The input parsing was extracted from `main` to a function(runLanguageServerLoop).
ProtocolHandlers now provide an interface to handle various LSP methods,
this interface is used by ClangdLSPServer.
Methods for code formatting were moved from ProtocolHandlers to ClangdServer.
ClangdLSPServer now provides a cleaner interface that only runs Language Server
input loop.

Summary:
This commit restores r303067(reverted by r303094) and fixes the 'formatting.test'

The failure is due to destructors of `ClangdLSPServer`'s fields(`FixItsMap` and
`FixItsMutex`) being called before destructor of `Server`. It led to the worker
thread calling `consumeDiagnostics` after `FixItsMutex` and `FixItsMap`
destructors were called.
Also, clangd is now run with '-run-synchronously' flag in 'formatting.test'.

Jakub Kuderski 4cdeb41072 [clang-tidy] modernize-use-emplace: Remove unnecessary make_tuple calls
Summary:
This patch makes modernize-use-emplace remove unnecessary make_ calls from push_back calls and turn them into emplace_back -- the same way make_pair calls are handled.
Custom make_ calls can be removed for custom tuple-like types -- two new options that control that are `TupleTypes` and `TupleMakeFunctions`. By default, the check removes calls to `std::make_pair` and `std::make_tuple`.

Eq.

```
std::vector<std::tuple<int, char, bool>> v;
v.push_back(std::make_tuple(1, 'A', true)); // --> v.emplace_back(1, 'A', true);
```

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`.

Benjamin Kramer d3326a04e0 [Clangd] Failed to decode params using 1.x-compatible request message
textDocument/completion sends a TextDocumentPositionParams message in the 2.x
and 3.x. But in 1.x it was instead a TextDocumentPosition with inlined
parameters. This means that the "uri" field is at the top level and not in
textDocument. Because of this, some clients that maintain compability with 1.x
have both uri and textDocument.uri. Clangd, however, early returns in the
presence of anything but 'textDocument' or 'position' which prevents a client
compatible with both 3.x and 1.x to work correctly. If Clangd was a bit more
permissive (no early return), clients implementing all the versions of the
protocol would work.

Summary:
The "performance-inefficient-vector-operation" check finds vector oprations in
for-loop statements which may cause multiple memory reallocations.

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.

Krasimir Georgiev 50117372db [clangd] Extract FsPath from file:// uri
Patch contributed by stanionascu!

rfc8089#appendix-E.2 specifies that paths can begin with a drive letter e.g. as file:///c:/.
In this case just consuming front file:// is not enough and the 3rd slash must be consumed to produce a valid path on windows.

The patch introduce a generic way of converting an uri to a filesystem path and back.

Haojian Wu 74f823a045 [clang-rename] Support renaming qualified symbol
Summary:
The patch adds a new feature for renaming qualified symbol references.
Unlike orginal clang-rename behavior, when renaming a qualified symbol to a new
qualified symbol (e.g "A::Foo" => "B::Bar"), this new rename behavior will
consider the prefix qualifiers of the symbol, and calculate the new prefix
qualifiers.  It aims to add as few additional qualifiers as possible.

As this is an early version (only supports renaming classes), I don't change
current clang-rename interfaces at the moment, and would like to keep its
(command-line tool) behavior. So I added new interfaces for the prototype.
In the long run, these interfaces should be unified.

No functionality changes in original clang-rename command-line tool.

This patch also contains a few bug fixes of clang-rename which are discovered by
the new unittest:

* fix a potential nullptr accessment when class declaration doesn't have definition.
* add USRs of nested declartaions in "getNamedDeclFor".

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.

Summary:
When changing namespaces, the tool adds leading "::" to references that need to
be fully-qualified, which would affect readability.

We avoid adding "::" when the symbol name does not conflict with the new
namespace name. For example, a symbol name "na::nb::X" conflicts with "ns::na"
since it would be resolved to "ns::na::nb::X" in the new namespace.

Use the LLVM_UTILS_PROVIDED variable to determine whether test tool
dependencies should be exposed for clang-tools-extra tests. If clang is
being built stand-alone and LLVM test tools (FileCheck, count and not)
are installed, the top-level CMakeLists.txt of clang sets this variable
to indicate that they will not be built as a part of this build,
and therefore no dependencies should be emitted for them. This fixes
the dependency errors when building clang stand-alone with tests

Benjamin Kramer 5957a19630 [clangd] Fix not being able to attach a debugger on macOS
Clangd is often waiting for input on getline as it awaits requests. If the
getline is interrupted, it causes the system call (read) to fail and the EINTR
error to be set. This can be seen when attaching a debugger such as LLDB on
macOS. On macOS (and possibly other operating systems), this system call is not
restarted after interruption but on Linux it is restarted which is why
attaching a debugger does work correctly there.

The solution is to work around the non-restarting system call by checking the
errno for EINTR when the stream fails and try again. This should be safe on all
Unixish platforms.

Sam McCall 9c5ebf7039 [include-fixer] Add fuzzy SymbolIndex, where identifier needn't match exactly.
Summary:
Add fuzzy SymbolIndex, where identifier needn't match exactly.

The purpose for this is global autocomplete in clangd. The query will be a
partial identifier up to the cursor, and the results will be suggestions.

It's in include-fixer because:

  - it handles SymbolInfos, actually SymbolIndex is exactly the right interface
  - it's a good harness for lit testing the fuzzy YAML index
  - (Laziness: we can't unit test clangd until reorganizing with a tool/ dir)

Other questionable choices:

  - FuzzySymbolIndex, which just refines the contract of SymbolIndex. This is
    an interface to allow extension to large monorepos (*cough*)
  - an always-true safety check that Identifier == Name is removed from
    SymbolIndexManager, as it's not true for fuzzy matching
  - exposing -db=fuzzyYaml from include-fixer is not a very useful feature, and
    a non-orthogonal ui (fuzziness vs data source). -db=fixed is similar though.

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.

Alexander Kornienko ce482d9269 [clang-tidy] Fix a few more issues in google-readability-casting
* suggest static_cast instead of reinterpret_cast for casts from void*
* top-level const doesn't need a const_cast
* don't emit a separate "possibly redundant cast" warning, instead suggest
  static_cast (in C++ only) and add a little hint to consider removing the cast

Alexander Kornienko d993e76a18 [clang-tidy] Function names configurable for cppcoreguidelines-nomalloc - checker
Summary:
Hello everybody,

this is an incremental patch for the NoMalloc-Checker I wrote. It allows to configure the memory-management functions, that are checked,
This might be helpful for a code base with custom functions in use, or non-standard functionality, like posix_memalign.

Benjamin Kramer f0af3e6b01 [clangd] Add support for FixIts.
Summary:
This uses CodeActions to show 'apply fix' actions when code actions are
requested for a location. The actions themselves make use of a
clangd.applyFix command which has to be implemented on the editor side. I
included an implementation for vscode.

This also adds a -run-synchronously flag which runs everything on the main
thread. This is useful for testing.

Haojian Wu b780c59b93 [clang-tidy] Fix a false positive on modernize-use-nullptr check.
Summary:
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.
