Eric Fiselier a2a6f85366 [clang-tidy]: Google: new check 'google-upgrade-googletest-case'
Introduce a new check to upgrade user code based on API changes in Googletest.

The check finds uses of old Googletest APIs with "case" in their name and replaces them with the new APIs named with "suite".

Bjorn Pettersson f0f63cab7f [clangd] Fix NDEBUG build problem introduced by rL366698
Sprinkled some #ifndef NDEBUG in Selection.cpp to make
it possible to build with NDEBUG defined.

The problem was introduced in rL366698 when using dlog
for some debug printouts. The dlog macro expands to
DEBUG_WITH_TYPE, which isn't using it's arguments in
optimized builds (when NDEBUG is defined).

Sam McCall 91e8eac73a [clangd] Support extraction of binary "subexpressions" like a + [[b + c]].
Summary:
These aren't formally subexpressions in C++, in this case + is left-associative.
However informally +, *, etc are usually (mathematically) associative and users
consider these subexpressions.

We detect these and in simple cases support extracting the partial expression.
As well as builtin associative operators, we assume that overloads of them
are associative and support those too.

Tom Roeder fc8c65b2e1 [clang-tidy] Add a module for the Linux kernel.
Summary:
Now that clang is going to be able to build the Linux kernel again on
x86, and we have gen_compile_commands.py upstream for generating
compile_commands.json, clang-tidy can be used on the Linux kernel
source.

To that end, this commit adds a new clang-tidy module to be used for
checks specific to Linux kernel source. The Linux kernel follows its own
style of C, and it will be useful to separate those checks into their
own module.

This also adds an initial check that makes sure that return values from
the kernel error functions like PTR_ERR and ERR_PTR are checked. It also
makes sure that any functions that directly return values from these
functions are checked.

Sam McCall 8faffec4e2 [clangd] Also accept flags from CLANGD_FLAGS variable.
This simplifies various workflows, particularly in debugging/development.
e.g. editors will tend to propagate flags, so you can run
`env CLANGD_FLAGS=-input-mirror-file=/tmp/mirror vim foo.cc` rather than
change the configuration in a persistent way.
(This also gives us a generic lever when we don't know how to customize
the flags in some particular LSP client).

While here, add a test for this and other startup logging, and fix a
couple of direct writes to errs() that should have been logs.

Sam McCall bdc6b6e410 [clangd] SelectionTree treats TranslationUnitDecl (mostly) consistently with other containers.
Summary:
Previously TranslationUnitDecl would never be selected.
This means root() is never null, and returns a reference.

commonAncestor() is in principle never null also, but returning TUDecl
here requires tweaks to be careful not to traverse it (this was already
possible when selecting multiple top-level decls, and there are associated bugs!)
Instead, never allow commonAncestor() to return TUDecl, return null instead.

Sam McCall 7fc8f415ea [clangd] Add dlog()s for SelectionTree, enabling -debug-only=SelectionTree.cpp
Summary:
SelectionTree is a RecursiveASTVisitor which processes getSourceRange() for
every node. This is a lot of surface area with the AST, as getSourceRange()
is specialized for *many* node types.
And the resulting SelectionTree depends on the source ranges of many
visited nodes, and the order of traversal.

Put together, this means we really need a traversal log to debug when we
get an unexpected SelectionTree. I've built this ad-hoc a few times, now
it's time to check it in.

Example output:
```

Kadir Cetinkaya 006d1915e2 [clangd] BackgroundIndex stores shards to the closest project
Summary:
Changes persistance logic to store shards at the directory of closest
CDB. Previously we were storing all shards to directory of the CDB that
triggered indexing, it had its downsides.

For example, if you had two TUs coming from a different CDB but depending on the
same header foo.h, we will store the foo.h only for the first CDB, and it would
be missing for the second and we would never persist it since it was actually
present in the memory and persisted before.

This patch still stores only a single copy of a shard, but makes the directory a
function of the file name. So that the shard place will be unique even with
multiple CDBs accessing the file. This directory is determined as the first
directory containing a CDB in the file's parent directories, if no such
directory exists we make use of the home directory.

Ilya Biryukov f81ee439a4 [clang-tidy] Adjust location of namespace comment diagnostic
Summary:
If there is no comment, place it at the closing brace of a namespace
definition. Previously it was placed at the next character after the
closing brace.

The new position produces a better location for highlighting in clangd
and does not seem to make matters worse for clang-tidy.

Matthias Gehre ffca322266 [clang-tidy] initial version of readability-convert-member-functions-to-static
Summary:
Finds non-static member functions that can be made ``static``.

I have run this check (repeatedly) over llvm-project. It made 1708 member functions
``static``. Out of those, I had to exclude 22 via ``NOLINT`` because their address
was taken and stored in a variable of pointer-to-member type (e.g. passed to
llvm::StringSwitch).
It also made 243 member functions ``const``. (This is currently very conservative
to have no false-positives and can hopefully be extended in the future.)

You can find the results here: https://github.com/mgehre/llvm-project/commits/static_const_eval

Sam McCall 9470142ca5 [clangd] Implementation of auto type expansion.
Add a tweak for clangd to replace an auto keyword to the deduced type.

This way a user can declare something with auto and then have the
IDE/clangd replace auto with whatever type clangd thinks it is. In case
of long/complext types this makes is reduces writing effort for the
user.

The functionality is similar to the hover over the auto keyword.

Example (from the header):

```
/// Before:
///    auto x = Something();
///    ^^^^
/// After:
///    MyClass x = Something();
///    ^^^^^^^
```

Don Hinton 43d75f9778 Recommit "[CommandLine] Remove OptionCategory and SubCommand caches from the Option class."
Previously reverted in 364141 due to buildbot breakage, and fixed here
by making GeneralCategory global a ManagedStatic.

Summary:
This change processes `OptionCategory`s and `SubCommand`s as they
are seen instead of caching them in the Option class and processing
them later.  Doing so simplifies the work needed to be done by the Global
parser and significantly reduces the size of the Option class to a mere 64
bytes.

Removing  the `OptionCategory` cache saved 24 bytes, and removing
the `SubCommand` cache saved an additional 48 bytes, for a total of a
72 byte reduction.

Sam McCall 2f760c44e6 [clangd] Rewrite of logic to rebuild the background index serving structures.
Summary:
Previously it was rebuilding every 5s by default, which was much too frequent
in the long run - the goal was to provide an early build. There were also some
bugs. There were also some bugs, and a dedicated thread was used in production
but not tested.

 - rebuilds are triggered by #TUs built, rather than time. This should scale
   more sensibly to fast vs slow machines.
 - there are two separate indexed-TU thresholds to trigger index build: 5 TUs
   for the first build, 100 for subsequent rebuilds.
 - rebuild is always done on the regular indexing threads, and is affected by
   blockUntilIdle. This means unit/lit tests run the production configuration.
 - fixed a bug where we'd rebuild after attempting to load shards, even if there
   were no shards.
 - the BackgroundIndexTests don't really test the subtleties of the rebuild
   policy (for determinism, we call blockUntilIdle, so rebuild-on-idle is enough

Summary:
I assume showing docs is going to be part of structured hover rendering, but
it's unclear whether that's going to make clangd 9 so this is low-hanging fruit.

Note: Since `StringLiteral::outputString` dumps most nonprintable
characters in octal value, the exact string literal format isn't preserved,
e.g. `"\x01"` becomes `'\001'`.

Sam McCall 674d8a947c [clangd] Use xxhash instead of SHA1 for background index file digests.
Summary:
Currently SHA1 is about 10% of our CPU, this patch reduces it to ~1%.

xxhash is a well-defined (stable) non-cryptographic hash optimized for
fast checksums (like crc32).
Collisions shouldn't be a problem, despite the reduced length:
 - for actual file content (used to invalidate bg index shards), there
   are only two versions that can collide (new shard and old shard).
 - for file paths in bg index shard filenames, we would need 2^32 files
   with the same filename to expect a collision. Imperfect hashing may
   reduce this a bit but it's well beyond what's plausible.

This will invalidate shards on disk (as usual; I bumped the version),
but this time the filenames are changing so the old files will stick
around :-( So this is more expensive than the usual bump, but would be
good to land before the v9 branch when everyone will start using bg index.

Francis Visoiu Mistrih e0308279cb [Bitcode] Move Bitstream to a separate library
This moves Bitcode/Bitstream*, Bitcode/BitCodes.h to Bitstream/.

This is needed to avoid a circular dependency when using the bitstream
code for parsing optimization remarks.

Since Bitcode uses Core for the IR part:

libLLVMRemarks -> Bitcode -> Core

and Core uses libLLVMRemarks to generate remarks (see
IR/RemarkStreamer.cpp):

Core -> libLLVMRemarks

we need to separate the Bitstream and Bitcode part.

For clang-doc, it seems that it doesn't need the whole bitcode layer, so
I updated the CMake to only use the bitstream part.

Haojian Wu 7c251fa069 [clangd] Collect the refs when the main file is header.
Summary:
Previously, we only collect refs of the symbols which are declared in
the preamble and referenced in the main file, it works well when the
main file is .cpp file.

However, when the main file is .h file (when opening a .h file in the
editor), we don't collect refs of the symbol declared in this file, so we miss
these refs in our dynamic index.

A typical scenario:

1. Open Foo.h (which contains class Foo)
2. Open Foo.cpp, call find references for Foo

And we only get refs from Foo.cpp.

JF Bastien 0e82895826 BitStream reader: propagate errors
The bitstream reader handles errors poorly. This has two effects:

 * Bugs in file handling (especially modules) manifest as an "unexpected end of
   file" crash
 * Users of clang as a library end up aborting because the code unconditionally
   calls `report_fatal_error`

The bitstream reader should be more resilient and return Expected / Error as
soon as an error is encountered, not way late like it does now. This patch
starts doing so and adopting the error handling where I think it makes sense.
There's plenty more to do: this patch propagates errors to be minimally useful,
and follow-ups will propagate them further and improve diagnostics.

Yitzhak Mandelbaum 039af0ea03 [clang-tidy] Generalize TransformerClangTidyCheck to take a rule generator.
Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

Yitzhak Mandelbaum 83b1580e1b [clang-tidy] Fix ClangTidyTest to initialize context before checks.
Summary:
Currently, `clang::tidy::test::runCheckOnCode()` constructs the check
instances *before* initializing the ClangTidyContext. This ordering causes
problems when the check's constructor accesses the context, for example, through
`getLangOpts()`.

This revision moves the construction to after the context initialization, which
follows the pattern used in the clang tidy tool itself.

Julie Hockett b1f01e27ec [clang-doc] Add basic support for templates and typedef
In serialize::parseBases(...), when a base record is a template
specialization, the specialization was used as the parent. It should be
the base template so there is only one file generated for this record.
When the specialized template is implicitly declared the reference USR
corresponded to the GlobalNamespace's USR, this will now be the base
template's USR.

More information about templates will be added later.

In serialize::emiInfo(RecorDecl*, ...), typedef records were not handled
and the name was empty. This is now handled and a IsTypeDef attribute is
added to RecordInfo struct.

In serialize::emitInfo(CXXMethodDecl*, ...), template specialization is
handled like in serialize::parseBases(...).

Bitcode writer and reader are modified to handle the new attribute of
RecordInfo.

Haojian Wu b5ce4e5ea3 [clangd] Perform merge for main file symbols.
Summary:
Previously, we randomly pick one main file symbol in dynamic index, we

It fixes the issue where sometimes we fail to go to the symbol definition, see:

1. call go-to-decl on Foo in Foo.cpp
2. jump to Foo.h, call go-to-def on Foo in Foo.h

we can't go back to Foo.cpp -- because we open Foo.cpp, Foo.h in clangd, both
files have Foo symbol (one with def&decl, one with decl only), we randomely
choose one.

Sam McCall 25c6257ba0 [clangd] Revamp textDocument/onTypeFormatting.
Summary:
The existing implementation (which triggers on }) is fairly simple and
has flaws:
 - doesn't trigger frequently/regularly enough (particularly in editors that type the }
 for you)
 - often reformats too much code around the edit
 - has jarring cases that I don't have clear ideas for fixing

This implementation is designed to trigger on newline, which feels to me more
intuitive than } or ;.
It does have allow for reformatting after other characters - it has a
basic behavior and a model for adding specialized behavior for
particular characters. But at least initially I'd stick to advertising
\n in the capabilities.

This also handles comment splitting: when you insert a line break inside
a line comment, it will make the new line into an aligned line comment.

Working on tests, but want people to patch it in and try it - it's hard to
see if "feel" is right purely by looking at a test.

Nikolai Kosjar 60e1296a9a [clang-tidy] Make the plugin honor NOLINT
Instantiate a ClangTidyDiagnosticConsumer also for the plugin case and
let it forward the diagnostics to the external diagnostic engine that is
already in place.

One minor difference to the clang-tidy executable case is that the
compiler checks/diagnostics are referred to with their original name.
For example, for -Wunused-variable the plugin will refer to the check as
"-Wunused-variable" while the clang-tidy executable will refer to that
as "clang-diagnostic- unused-variable". This is because the compiler
diagnostics never reach ClangTidyDiagnosticConsumer.

This commit updates the check as follows:
(1) Do not emit fixes for extern global constants.
(2) Allow the second character of prefixes for constants to be numeric (the new guideline is that global constants should generally be named with a prefix that begins with a capital letter followed by one or more capital letters or numbers).

Chris Bieneman 760a9ee63c Support codesigning bundles and forcing
Summary:
Clangd's framework is assembled by copying binaries from the lib and bin directories into a bundle shape. This results in an invalid bundle code signature because the signature only applies to the binaries not the resources.

This patch adds two new options to `llvm_codesign` to enable re-signing the library and XPC service as bundles.

The `BUNDLE_PATH` option allow specifying an explicit path to codesign, which enables signing bundles which aren't generated using CMake's `FRAMEWORK` or `BUNDLE` target properties.

The `FORCE` option allows re-signing binaries that have already been signed. This is required for how clangd exposes the clangd library and tools as both XPC and non-XPC services using the same binary.
