Jonas Toth 82536501c7 [fix][clang-tidy] fix for r345961 that introduced a test failure on Windows builds
r345961 introduced a path check in
.\tools\clang\tools\extra\test\clang-tidy\clang-tidy-run-with-database.cpp.

r345961 added a check line for a path that only handled / on unix
machines and not \ on windows machines.

This patch handles both cases.

Sam McCall 2eb6b4038a [clangd] Remove didOpen extraFlags extension.
Summary:
This was added in D34947 to support YCM, but YCM actually provides *all* args,
and this was never actually used.
Meanwhile, we grew another extension that allows specifying all args.

I did find one user of this extension: https://github.com/thomasjo/atom-ide-cpp.
I'll reach out, there are multiple good alternatives:
 - compile_commands.txt can serve the same purpose as .clang_complete there
 - we can add an extension to support setting the fallback command

Sam McCall cb50e23ba8 [clang-tidy] Get ClangTidyContext out of the business of storing diagnostics. NFC
Summary:
Currently ClangTidyContext::diag() sends the diagnostics to a
DiagnosticsEngine, which probably delegates to a ClangTidyDiagnosticsConsumer,
which is supposed to go back and populate ClangTidyContext::Errors.

After this patch, the diagnostics are stored in the ClangTidyDiagnosticsConsumer
itself and can be retrieved from there.

Why?
 - the round-trip from context -> engine -> consumer -> context is confusing
   and makes it harder to establish layering between these things.
 - context does too many things, and makes it hard to use clang-tidy as a library
 - everyone who actually wants the diagnostics has access to the ClangTidyDiagnosticsConsumer

The most natural implementation (ClangTidyDiagnosticsConsumer::take()
finalizes diagnostics) causes a test failure: clang-tidy-run-with-database.cpp
asserts that clang-tidy exits successfully when trying to process a file
that doesn't exist.
In clang-tidy today, this happens because finish() is never called, so the
diagnostic is never flushed. This looks like a bug to me.
For now, this patch carefully preserves that behavior, but I'll ping the
authors to see whether it's deliberate and worth preserving.

This patch introduces a new clang-tidy check that matches on all `declStmt` that declare more then one variable
and transform them into one statement per declaration if possible.

It currently only focusses on variable declarations but should be extended to cover more kinds of declarations in the future.
It is related to https://reviews.llvm.org/D27621 and does use it's extensive test-suite. Thank you to firolino for his work!

Roman Lebedev c367ba1923 [clang-tidy] cppcoreguidelines-macro-usage: print macro names
Summary:
The macro may not have location (or more generally, the location may not exist),
e.g. if it originates from compiler's command-line.

The check complains on all the macros, even those without the location info.
Which means, it only says it does not like it. What is 'it'? I have no idea.
If we don't print the name, then there is no way to deal with that situation.

And in general, not printing name here forces the user to try to understand,
given, the macro definition location, what is the macro name?
This isn't fun.

Also, ignores-by-default the macros originating from command-line,
with an option to not ignore those.

I suspect some more issues may crop up later.

Summary:
Detects when the integral literal or floating point (decimal or hexadecimal)
literal has non-uppercase suffix, and suggests to make the suffix uppercase,

All valid combinations of suffixes are supported.

```
  auto x = 1;  // OK, no suffix.

  auto x = 1u; // warning: integer literal suffix 'u' is not upper-case

  auto x = 1U; // OK, suffix is uppercase.

  ...
```

This is a re-commit, the original was reverted by me in

Summary:
Finds classes that not only contain the data (non-static member variables),
but also have logic (non-static member functions), and diagnoses all member
variables that have any other scope other than `private`. They should be
made `private`, and manipulated exclusively via the member functions.

Optionally, classes with all member variables being `public` could be
ignored, and optionally all `public` member variables could be ignored.

Options
-------

* IgnoreClassesWithAllMemberVariablesBeingPublic

  Allows to completely ignore classes if **all** the member variables in that
  class have `public` visibility.

* IgnorePublicMemberVariables

  Allows to ignore (not diagnose) **all** the member variables with `public`
  visibility scope.

Sam McCall 3d0adbe636 [clangd] Enforce rules around "initialize" request, and create ClangdServer lazily.
Summary:
LSP is a slightly awkward map to C++ object lifetimes: the initialize request
is part of the protocol and provides information that doesn't change over the
lifetime of the server.

Until now, we handled this by initializing ClangdServer and ClangdLSPServer
right away, and making anything that can be set in the "initialize" request
mutable.
With this patch, we create ClangdLSPServer immediately, but defer creating
ClangdServer until "initialize". This opens the door to passing the relevant
initialize params in the constructor and storing them immutably.
(That change isn't actually done in this patch).

To make this safe, we have the MessageDispatcher enforce that the "initialize"
method is called before any other (as required by LSP). That way each method
handler can assume Server is initialized, as today.

As usual, while implementing this I found places where our test cases violated
the protocol.

Sam McCall 2c30fbcac5 [clangd] Lay JSONRPCDispatcher to rest.
Summary:
Most of its functionality is moved into ClangdLSPServer.
The decoupling between JSONRPCDispatcher, ProtocolCallbacks, ClangdLSPServer
was never real, and only served to obfuscate.

Some previous implicit/magic stuff is now explicit:
 - the return type of LSP method calls are now in the signature
 - no more reply() that gets the ID using global context magic
 - arg tracing no longer relies on RequestArgs::stash context magic either

This is mostly refactoring, but some deliberate fixes while here:
 - LSP method params are now by const reference
 - notifications and calls are now distinct namespaces.
   (some tests had protocol errors and needed updating)
 - we now reply to calls we failed to decode
 - outgoing calls use distinct IDs
A few error codes and message IDs changed in unimportant ways (see tests).

Jonas Toth 78886233b3 [clang-tidy] New checker for not null-terminated result caused by strlen(), size() or equal length
New checker called bugprone-not-null-terminated-result. This check finds function calls where it is possible to cause a not null-terminated result. Usually the proper length of a string is strlen(src) + 1 or equal length of this expression, because the null terminator needs an extra space. Without the null terminator it can result in undefined behaviour when the string is read.

The following function calls are checked:
memcpy, wmemcpy, memcpy_s, wmemcpy_s, memchr, wmemchr, memmove, wmemmove, memmove_s, wmemmove_s, memset, wmemset, strerror_s, strncmp, wcsncmp, strxfrm, wcsxfrm

The following is a real-world example where the programmer forgot to increase the passed third argument, which is size_t length. That is why the length of the allocated memory is problematic too.

static char *StringCpy(const std::string &str) {
  char *result = reinterpret_cast<char *>(malloc(str.size()));
  memcpy(result, str.data(), str.size());
  return result;
}

After running the tool fix-it rewrites all the necessary code according to the given options. If it is necessary, the buffer size will be increased to hold the null terminator.

static char *StringCpy(const std::string &str) {
  char *result = reinterpret_cast<char *>(malloc(str.size() + 1));
  strcpy(result, str.data());
  return result;
}

Adam Balogh abd72e9851 [clang-tidy] White List Option for performance-unnecessary-value-param, performance-unnecessary-copy-initialization and performance-for-range-copy
New option added to these three checks to be able to silence false positives on
types that are intentionally passed by value or copied. Such types are e.g.
intrusive reference counting pointer types like llvm::IntrusiveRefCntPtr. The
new option is named WhiteListTypes and can contain a semicolon-separated list of
names of these types. Regular expressions are allowed. Default is empty.
