Nico Weber e028de43cd check-clang-tools: Actually build and run XPC test
The CMake variable controlling if XPC code is built is called
CLANGD_BUILD_XPC but three places unintentionally checked the
non-existent variable CLANGD_BUILD_XPC_SUPPORT instead, which (due to
being nonexistent, and due to cmake) always silently evaluated to false.

Luckily the test still seems to pass, despite never running after being
added almost 3 months ago in r351280.

Nico Weber fee435702d gn build: Add build files for clangd xpc framework code
This is a bit of a larger change since this is the first (and as far as
I can tell only) place where the LLVM build produces macOS framework
bundles.

GN has some built-in support for this, so use that.
`gn help create_bundle` has a terse description (but it's a bit
outdated: `deps` must be `public_deps` and the conditionals in the
example in the help aren't quite right on non-iOS).

We need a new 'copy_bundle_data' tool, and since we copy the clangd.xpc
bundle as bundle_data into ClangdXPC.framework it needs to be able to
handle directories in addition to files.

GN also insists we have a compile_xcassets tool even though it's not
used. I just made that run `false`.

Despite GN's support for bundles, we still need to manually create the
expected symlink structure in the .framework bundle. Since this code
never runs on Windows, it's safe to create the symlinks before the
symlink targets exist, so we can just make the bundle depend on the
steps that create the symlinks. For this to work, change the symlink
script to create the symlink's containing directory if it doesn't yet
exist.

I locally verified that CMake and GN build create the same bundle
structure. (I noticed that both builds set LC_ID_DYLIB to the pre-copy
libClangdXPCLib.dylib name, but that seems to not cause any issues and
it happens in the CMake build too.)

(Also add an error message to clangd-xpc-test-client for when loading
the dylib fails – this was useful while locally debugging this.)

Summary:
Finally, we are here!

Analyzes OpenMP Structured Blocks and checks that no exception escapes
out of the Structured Block it was thrown in.

As per the OpenMP specification, structured block is an executable statement,
possibly compound, with a single entry at the top and a single exit at the
bottom. Which means, ``throw`` may not be used to to 'exit' out of the
structured block. If an exception is not caught in the same structured block
it was thrown in, the behaviour is undefined / implementation defined,
the program will likely terminate.

Stephane Moore 5f70c473c9 [clang-tidy] Disable google-runtime-int in Objective-C++ 🔓
Summary:
In contrast to Google C++, Objective-C often uses built-in integer types
other than `int`. In fact, the Objective-C runtime itself defines the
types NSInteger¹ and NSUInteger² which are variant types depending on
the target architecture. The Objective-C style guide indicates that
usage of system types with variant sizes is appropriate when handling
values provided by system interfaces³. Objective-C++ is commonly the
result of conversion from Objective-C to Objective-C++ for the purpose
of integrating C++ functionality. The opposite of Objective-C++ being
used to expose Objective-C functionality to C++ is less common,
potentially because Objective-C has a signficantly more uneven presence
on different platforms compared to C++. This generally predisposes
Objective-C++ to commonly being more Objective-C than C++. Forcing
Objective-C++ developers to perform conversions between variant system types
and fixed size integer types depending on target architecture when
Objective-C++ commonly uses variant system types from Objective-C is
likely to lead to more bugs and overhead than benefit. For that reason,
this change proposes to disable google-runtime-int in Objective-C++.

[3] "Types long, NSInteger, NSUInteger, and CGFloat vary in size between
32- and 64-bit builds. Use of these types is appropriate when handling
values exposed by system interfaces, but they should be avoided for most
other computations."

Ilya Biryukov 373bee85c2 [clangd] Tune the fuzzy-matching algorithm
Summary:
To reduce the gap between prefix and initialism matches.

The motivation is producing better scoring in one particular example,
but the change does not seem to cause large regressions in other cases.

The examples is matching 'up' against 'unique_ptr' and 'upper_bound'.
Before the change, we had:
  - "[u]nique_[p]tr" with a score of 0.3,
  - "[up]per_bound" with a score of 1.0.

A 3x difference meant that symbol quality signals were almost always ignored
and 'upper_bound' was always ranked higher.

However, intuitively, the match scores should be very close for the two.

After the change we have the following scores:
- "[u]nique_[p]tr" with a score of 0.75,
- "[up]per_bound" with a score of 1.0.

Summary:

work with different STL implementations, fix clangd/clangd#9.

To generate the symbol mapping, we parse the cppreference symbol index
page to build a lookup table.

The mapping is not completed, a few TODOs:
  - support symbols from different headers (e.g. std::move)
  - support STL macros
  - support symbols from std's sub-namespaces (e.g. chrono)

Summary:

clang tool invocations adjust commands normally like this. In clangd we have
different code paths for invoking a frontend action(preamble builds, ast builds,
background index, clangd-indexer) they all work on the same GlobalCompilationDatabase
abstraction, but later on are subject to different modifications.

This patch makes sure all of the clangd actions make use of the same compile
commands before invocation.

Enables background-index to work on chromium codebase(since they had dependency
file output in their compile commands).

would be install-clang-headers. Rename the existing target to
install-clang-resource-headers to free up the install-clang-headers name
for the new target, following the discussion on cfe-dev [1].

I didn't find any bots on zorg referencing install-clang-headers. I'll
send out another PSA to cfe-dev to accompany this rename.

Paul Hoad 68f5e5456f [clang-tidy] add OverrideMacro to modernize-use-override check
Summary:
The usefulness of **modernize-use-override** can be reduced if you have to live in an environment where you support multiple compilers, some of which sadly are not yet fully C++11 compliant

some codebases have to use override as a macro OVERRIDE e.g.

```
// GCC 4.7 supports explicit virtual overrides when C++11 support is enabled.
```

This allows code to be compiled with C++11 compliant compilers and get warnings and errors that clang, MSVC,gcc can give, while still allowing other legacy pre C++11 compilers to compile the code. This can be an important step towards modernizing C++ code whilst living in a legacy codebase.

When it comes to clang tidy, the use of the **modernize-use-override** is one of the most useful checks, but the messages reported are inaccurate for that codebase if the standard approach is to use the macros OVERRIDE and/or FINAL.

When combined with fix-its that introduce the C++11 override keyword, they become fatal, resulting in the modernize-use-override check being turned off to prevent the introduction of such errors.

This revision, allows the possibility for the replacement **override **to be a macro instead, Allowing the clang-tidy check to be run on  both pre and post C++11 code, and allowing fix-its to be applied.

```
struct Foo{ Foo(int); };
void bar(Foo);
vod foo() {
  int x;
  bar(^x);
}
```
Performing a GoTo on the point specified by ^ would give two results one
pointing to line `int x` and the other for definition of `Foo(int);`

a binary answer whether an exception could occur and if yes which types are
thrown.
This refactoring allows keeping track if there is a unknown factor, because the
code calls to some functions with unavailable source code with no `noexcept`
information.
This 'potential Unknown' information is propagated properly and can be queried
separately.

when handling a qualifier that is unresolved, we change the unresolved name and
scopes so that the fixer will fix "clang::clangd::X" in the following example.

For example, if an index symbol has location in a .proto file and an AST symbol
has location in a generated .proto.h file, then we prefer location in .proto
which is more meaningful to users.

Also use `mergeSymbols` to get the preferred location between AST location and index location in go-to-def.

Malcolm Parsons 297b6a2b6e [clang-tidy] Don't use assignment for value-initialized enums
Summary:
The modernize-use-default-member-init check crashes when trying to
create an assignment value for a value-initialized enum because it isn't a
BuiltinType.
An enum cannot be initialized by assigning 0 to it unless a cast is added.
It could be initialized with an enumerator with the value 0, but there might not
be one.
Avoid these issues by ignoring the UseAssignment setting for value-initialized
enums.

Fixes PR35050.

Paul Hoad 6bfd721571 [clang-tidy] Add options to bugprone-argument-comment to add missing argument comments to literals
bugprone-argument-comment only supports identifying those comments which do not match the function parameter name

This revision add 3 options to adding missing argument comments to literals (granularity on type is added to control verbosity of fixit)

```
CheckOptions:
  - key:             bugprone-argument-comment.CommentBoolLiterals
    value:           '1'
  - key:             bugprone-argument-comment.CommentFloatLiterals

  - key:             bugprone-argument-comment.CommentNullPtrs

Sam McCall 2048f22892 [clangd] Lib to compute and represent selection under cursor.
Summary:
The primary problem this solves is to expose the codeAction selection to
AST-based refactorings in a way that makes it easy and efficient for them to
bind to the right parts of the AST.

It should also allow us to make XRefs based features (textDocument/definition)
more robust, more easily implement textDocument/typeDefinition etc.
As an example, template parameter references can be identified without special
handling.
There should be slight speedup too: we can prune most of the AST traversal
in most cases.

Elephant in the room: this is similar-but-different to Tooling/Refactoring/ASTSelection.
That captures a smaller set of AST nodes, has a slightly different way of
representing selections, and generally has mare features and does more work.
The overall shape is pretty similar, and yet I can't quite get to behave as I
expect.

Sam McCall 866ba2c924 [clangd] Implement textDocument/declaration from LSP 3.14
Summary:
LSP now reflects the declaration/definition distinction.

Language server changes:
 - textDocument/definition now returns a definition if one is found, otherwise
   the declaration. It no longer returns declaration + definition if they are
   distinct.
 - textDocument/declaration returns the best declaration we can find.
 - For macros, the active macro definition is returned for both methods.
 - For include directive, the top of the target file is returned for both.
There doesn't appear to be a discovery mechanism (we can't return everything to
clients that only know about definition), so this changes existing behavior.
In practice, it should greatly reduce the fraction of the time we need to show
the user a menu of options.

C++ API changes:
 - findDefinitions is replaced by locateSymbolAt, which returns a
   vector<LocatedSymbol> - one for each symbol under the cursor.
 - this contains the preferred declaration, the definition (if found), and
   the symbol name
This API enables some potentially-neat extensions, like swapping between decl
and def, and exposing the symbol name to the UI in the case of multiple symbols.

Jonas Toth 9b127421b6 [clang-tidy] refactor bugprone-exception-escape analysis into class
Summary:
The check `bugprone-exception-escape` does an AST-based analysis to determine
if a function might throw an exception and warns based on that information.
The analysis part is refactored into a standalone class similiar to
`ExprMutAnalyzer` that is generally useful.
I intent to use that class in a new check to automatically introduce `noexcept`
if possible.

Ilya Biryukov c6ed77812b [clangd] Drop fixes if replying with tweaks resulted in an error
This should not happen in normal operation, as it implies that the diagnostics
with some available fixes were produced but the AST is invalid.
Moreover, the code had an error: always returned code actions ignoring the
SupportsCodeAction capability and writing a test for this is impossible,
since this can only happen due to programmer's error rather than invalid inputs.

This fixes most references to the paths:
 llvm.org/svn/
 llvm.org/git/
 llvm.org/viewvc/
 github.com/llvm-mirror/
 github.com/llvm-project/
 reviews.llvm.org/diffusion/

to instead point to https://github.com/llvm/llvm-project.

This is *not* a trivial substitution, because additionally, all the
checkout instructions had to be migrated to instruct users on how to
use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of
checking out various projects into various subdirectories.

I've attempted to not change any scripts here, only documentation. The
scripts will have to be addressed separately.

Ilya Biryukov cce67a32cf [clangd] Interfaces for writing code tweaks
Summary:
The code tweaks are an implementation of mini-refactorings exposed
via the LSP code actions. They run in two stages:
  - Stage 1. Decides whether the action is available to the user and
    collects all the information required to finish the action.
    Should be cheap, since this will run over all the actions known to
    clangd on each textDocument/codeAction request from the client.

  - Stage 2. Uses information from stage 1 to produce the actual edits
    that the code action should perform. This stage can be expensive and
    will only run if the user chooses to perform the specified action in
    the UI.

One unfortunate consequence of this change is increased latency of
processing the textDocument/codeAction requests, which now wait for an
AST. However, we cannot avoid this with what we have available in the LSP
today.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Chandler Carruth 469bdefd44 Install new LLVM license structure and new developer policy.
This installs the new developer policy and moves all of the license
files across all LLVM projects in the monorepo to the new license
structure. The remaining projects will be moved independently.

Note that I've left odd formatting and other idiosyncracies of the
legacy license structure text alone to make the diff easier to read.
Critically, note that we do not in any case *remove* the old license
notice or terms, as that remains necessary until we finish the
relicensing process.

I've updated a few license files that refer to the LLVM license to
instead simply refer generically to whatever license the LLVM project is
under, basically trying to minimize confusion.

This is really the culmination of so many people. Chris led the
community discussions, drafted the policy update and organized the
multi-year string of meeting between lawyers across the community to
figure out the strategy. Numerous lawyers at companies in the community
spent their time figuring out initial answers, and then the Foundation's
lawyer Heather Meeker has done *so* much to help refine and get us ready
here. I could keep going on, but I just want to make sure everyone
realizes what a huge community effort this has been from the begining.

Martin Bohme c4db59c63c [clang-tidy] Treat references to smart pointers correctly in use-after-move.
Summary:
Previously, we weren't recognizing these as smart pointers and thus
weren't allowing non-dereference accesses as we should -- see new test
cases which fail without the fix.

Paul Hoad b16e288c7d [clang-tidy] add options documentation to readability-identifier-naming checker
Summary:
The documentation for this clang-checker did not explain what the options are. But this checkers only works with at least some options defined.

To discover the options, you have to read the source code. This shouldn't be necessary for users who just have access to the clang-tidy binary.

This revision, explains the options and gives an example.

Patch by MyDeveloperDay.

Summary:
Files without any symbols were never marked as updated during indexing, which resulted in failure while writing shards for these files.

This patch fixes the logic to mark files that are seen for the first time but don't contain any symbols as updated.

Sam McCall 2dccf13538 [clangd] Unlink VFS working dir from OS working dir.
A lot of our previous FS manipulation was thread-unsafe in practice with
the RealFS implementation.

This switches to a different RealFS mode where path-manipulation is used
to simulate multiple working dirs.
r351050 both added this mode and removed the cache. If we want to
move back to the old implementation we need to put the cache back.

Jonas Toth 6a9f831ffd [clang-tidy] Fix case of local variables in modernize-use-nodiscard checker
Summary:
Correct the case of the local variables..

Rational:
I want to be able to run clang-tidy on new clang-tidy checker code prior to creating a review (to demonstrate we should dog food our own tools during development, not my suggestion but @Eugene.Zelenko)

To this end I am running the following in a script, prior to make a change.

```
tidy:
    @for source in $$(git status -suno | grep ".cpp$$" | cut -c4-) ;\
    do \
        clang-tidy -quiet  $$source -- $(TIDY_FLAGS);\
    done

```

I then want to go through the checkers and see which checkers most closely match the review style of the reviewers

```
---
Checks:          '
-clang-diagnostic-*,
readability-identifier-naming,
llvm-header-guard
'
WarningsAsErrors: ''
HeaderFilterRegex: ''
AnalyzeTemporaryDtors: false
FormatStyle:     LLVM
CheckOptions:
  - key:             readability-identifier-naming.IgnoreFailedSplit
    value:           '0'
  - key:             readability-identifier-naming.VariableCase
    value:           'CamelCase'
  - key:             readability-identifier-naming.LocalVariableCase
    value:           'CamelCase'
...

```

Unfortunately in doing so, I have identified that my previous review {D55433} it violates what looks like to be the convention of local variables being in CamelCase.

Sending this small review in the hope it can be corrected.

This would save us some memory and disk space:
  - Dex usage (261 MB vs 266 MB)
  - Disk (75 MB vs 76 MB)

It would save more when we index the main file symbol D55185.
