Our testing didn't reflect reality: live clangd almost always uses a
preamble, and sometimes the preamble behaves differently.
This patch fixes a common test helper to be more realistic.
Preamble doesn't preserve information about which tokens come from the
command-line (this gets inlined into a source file). So remove logic
that attempts to treat symbols with such names differently.
A SymbolCollectorTest tries to verify that locals in headers are not
indexed, with preamble enabled this is only meaningful for locals of
auto-typed functions (otherwise the bodies aren't parsed).
Tests were relying on the fact that the findAnyDecl helper actually did expose
symbols from headers. Resolve by making all these functions consistently
able to find symbols in headers/preambles.

Summary:
Clang's hierarchy is CompilerInstance -> DiagnosticsEngine -> DiagnosticConsumer.
(Ownership is optional/shared, but this structure is fairly clear).
Currently ClangTidyDiagnosticConsumer *owns* the DiagnosticsEngine:
- this inverts the hierarchy, which is confusing
- this means ClangTidyDiagnosticConsumer() mutates the passed-in context, which
is both surprising and limits flexibility
- it's not possible to use a different DiagnosticsEngine with ClangTidy
This means a little bit more code in the places ClangTidy is used standalone,
but more flexibility in using ClangTidy with other diagnostics configurations.

entirely redundant, and indeed all the tests pass.
This solves a problem with embedding clang-tidy: if using a DiagnosticsEngine
which already has file state, re-setting its SourceManager (to the same value)
causes an assertion.
(There are other ways to solve this problem, but this is the simplest).

The size of an os_log buffer is known at any stage of compilation, so making it
a constant expression means that the common idiom of declaring a buffer for it
won't result in a VLA. That allows the compiler to skip saving and restoring
the stack pointer around such buffers.
This also moves the OSLog and other FormatString helpers from
libclangAnalysis to libclangAST to avoid a circular dependency.

The new implementation is a GlobalCompilationDatabase that overlays a base.
Normally this is the directory-based CDB.
To preserve the behavior of compile_args_from=LSP, the base may be null.
The OverlayCDB is always present, and so the extensions to populate it
are always supported.
It also allows overriding the flags of the fallback command. This is
just unit-tested for now, but the plan is to expose this as an extension
on the initialize message. This addresses use cases like

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 should not introduce any behavior changes. It consists of

1. Replacing fall through comments with the LLVM_FALLTHROUGH macro
2. Inserting 'break' before falling through into a case block consisting
of only 'break'.
We were already using this warning with GCC, but its warning behaves
slightly differently. In this patch, the following differences are
relevant:
1. GCC recognizes comments that say "fall through" as annotations, clang
doesn't
2. GCC doesn't warn on "case N: foo(); default: break;", clang does
3. GCC doesn't warn when the case contains a switch, but falls through
the outer case.
I will enable the warning separately in a follow-up patch so that it can
be cleanly reverted if necessary.

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 kept the error (instead of downgrading to a log message) since the range lengths differing does indicate either a bug in the client or server range calculation or the buffers being out of sync (which both seems serious enough to me to be an error). If any existing clients aside from VSCode break they should only break when accidentally typing a Unicode character which should only be a minor nuisance for a little while until the bug is fixed in the respective client.

Standardize on the most common namespace setup in our *.cpp files:

And remove redundant llvm:: qualifiers. (Except for cases like
make_unique where this causes problems with std:: and ADL).
This choice is pretty arbitrary, but some broad consistency is nice.
This is going to conflict with everything. Sorry :-/
Squash the other configurations:
A)
using namespace llvm;
using namespace clang;
using namespace clangd;
void clangd::foo(StringRef);
This is in some of the older files. (It prevents accidentally defining a

void foo(llvm::StringRef) { ... }
This is fine, but in practice the using directive often gets added over time.
C)

This was pretty common, but is a bit misleading: name lookup preferrs

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.

Most of its functionality is moved into ClangdLSPServer.

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

This would buy us more memory. Using a 32-bits integer is enough for
most human-readable source code (up to 4M lines and 4K columns).
Previsouly, we used 8 bytes for a position, now 4 bytes, it would save
us 8 bytes for each Ref and each Symbol instance.
For LLVM-project binary index file, we save ~13% memory.

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));

Summary:
I think this was just copied from somewhere with the belief that it actually
did some crash handling.
Of course the question arises: *should* we set one? I don't think so:
- clangd used to crash a lot, now it's pretty stable, because we found and
fixed the crashes. I think the long-term effects of crashing hard are good.
- the implementation can't do any magic, it just uses longjmp to return without
running any destructors by default. This is unsafe in general (e.g. mutexes
won't unlock) and will certainly end up leaking memory. Whatever UB caused
the crash may still stomp all over global state, etc.
I think there's an argument for isolating the background indexer (autoindex)
because it's not directly under the user's control, the crash surface is larger,
and it doesn't particularly need to interact with the rest of clangd.
But there, fork() and communicate through the FS is safer.

The bug being fixed: when a posting list doesn't exist in the index, it
was previously just dropped from the query rather than being treated as
empty. Now that we have the FALSE iterator, we can use it instead.
The query tree logic previously had a bunch of special cases to detect whether
subtrees are empty. Now we just naively build the whole tree, and rely
on the query optimizations to drop the trivial parts.
Finally, there was a bug in trigram generation: the empty query would
generate a single trigram "$$$" instead of no trigrams.
This had no effect (there was no posting list, so the other bug
cancelled it out). But we now have to fix this bug too.

commit 233092a0 (Add 'let' to the help message., 2015-02-27).
Implement the `l` command now for completeness.

Conditionally compile the parts of clang-tidy which depend on the static
analyzer.
Funnily enough, I made the patch to exclude this from the build in 2013,
and it was committed with the comment that the tool should not be fully
excluded, but only the parts of it which depend on the analyzer should
be excluded.

This commit implements that idea.

check-clangd is included via check-clang-tools, otherwise we will run two
instances of check-clangd in parallel when running 'check-all',
which may have race condition.
llvm-svn: 343526
Summary:
So we don't have to run "check-clang-tools" (which builds and tests all
clang tools) to verify our clangd-related change. It'd save waiting time for
clangd developers.
check-clangd (build ~1000 files, run ~340 tests) vs check-clang-tools (build
~3000 files, run ~1000 tests).
In the future, we probably want to add similar target for other
clang-tools (e.g. clang-tidy).

Summary:
When no scope qualifier is specified, allow completing index symbols
from any scope and insert proper automatically. This is still experimental and
hidden behind a flag.
Things missing:
- Scope proximity based scoring.
- FuzzyFind supports weighted scopes.

Summary:
If we have some range information coming from clang diagnostic, promote
that one even if it doesn't contain diagnostic location inside.
