Summary:
These decls are sometime used as the canonical declarations (e.g. for go-to-def),
which seems to be bad.
- friend decls that are not definitions should be ignored for indexing purposes
- this means they should never be selected as canonical decl
- if the friend decl is the only decl, then the symbol should not be indexed

Summary:
After this commit, clangd will only keep the last 3 accessed ASTs in
memory. Preambles for each of the opened files are still kept in
memory to make completion and AST rebuilds fast.
AST rebuilds are usually fast enough, but having the last ASTs in
memory still considerably improves latency of operations like
findDefinition and documeneHighlight, which are often sent multiple
times a second when moving around the code. So keeping some of the last
accessed ASTs in memory seems like a reasonable tradeoff.

Summary:
In rL327851 the createUniqueFile() and createTemporaryFile()
variants that do not return the file descriptors were changed to
create empty files, rather than only check if the paths are free.
This change was done in order to make the functions race-free.
That change led to clang-tidy (and possibly other tools) leaving
behind temporary assembly files, of the form placeholder-*, when
using a target that does not support the internal assembler.
The temporary files are created when building the Compilation
object in stripPositionalArgs(), as a part of creating the
compilation database for the arguments after the double-dash. The
files are created by Driver::GetNamedOutputPath().
Fix this issue by cleaning out temporary files at the deletion of
Compilation objects.
This fixes https://bugs.llvm.org/show_bug.cgi?id=37091.

The commit includes two changes:
1. Set DisableFree to false when building the ParsedAST.
This is sane default, since clangd never wants to leak the AST.
2. Make sure CompilerInstance created in code completion is passed to
the FrontendAction::BeginSourceFile call.
We have to do this to make sure the memory buffers of remapped
files are properly freed.
Our tests do not produce any warnings under asan anymore.
The changes are mostly trivial, just moving the code around. So
sending without review.
llvm-svn: 333370
This fix is still quite fragile, the underlying problem is that the
code should not rely on source ranges coming from the preamble to be
correct when reading from the text buffers.
This is probably not possible to achieve in practice, so we would
probably have to keep the contents of old headers around for the
lifetime of the preamble.
llvm-svn: 333369
It turns out that our fix did not solve the problem completely and the
crash due to stale preamble is still there under asan.
Disabling the test for now, will reenable it when landing a proper fix

Summary:
This is more efficient and avoids data races when reading files that
come from the preamble. The staleness can occur when reading a file
from disk that changed after the preamble was built. This can lead to

We do not to rely on symbols from the main file anyway, since any info
that those provide can always be taken from the AST.

To fix a crash in code completion that occurrs when reading doc
comments from files that were updated after the preamble was

The current workaround is to not provide comments from the headers at
all and rely on the dynamic index instead.
A more principled solution would be to store contents of the files
read inside the preamble, but it is way harder to implement properly,
given that it would definitely increase the sizes of the preamble.
Together with D47272, this should fix all preamble-related crashes

Summary:
Currently, we only handle the first callback from sema code completion
and ignore results from potential following callbacks. This causes
causes loss of completion results when multiple contexts are tried by Sema.
For example, we wouldn't get any completion result in the following completion
as the first attemped context is natural language which has no
candidate. The parser would backtrack and tried a completion with AST
semantic, which would find candidate "::x".
```
void f(const char*, int);
#define F(x) f(#x, x)
int x;
void main() {
F(::^);
}
```
To fix this, we only process a sema callback when it gives completion results or
the context supports index-based completion.

Summary:
Code completion scoring was embedded in CodeComplete.cpp, which is bad:
- awkward to test. The mechanisms (extracting info from index/sema) can be
unit-tested well, the policy (scoring) should be quantitatively measured.
Neither was easily possible, and debugging was hard.
The intermediate signal struct makes this easier.
- hard to reuse. This is a bug in workspaceSymbols: it just presents the
results in the index order, which is not sorted in practice, it needs to rank
them!
Also, index implementations care about scoring (both query-dependent and
independent) in order to truncate result lists appropriately.
The main yak shaved here is the build() function that had 3 variants across
unit tests is unified in TestTU.h (rather than adding a 4th variant).

As discussed in D45931, currently, profiling output of clang-tidy is somewhat not great.
It outputs one profile at the end of the execution, and that profile contains the data

not accumulated, it is simply discarded.
It would be nice to improve this.
This differential is the first step - make this profiling info per-TU,
and output it after the tool has finished processing each TU.
In particular, when `ClangTidyASTConsumer` destructor runs.
Next step will be to add a CSV (JSON?) printer to store said profiles under user-specified directory prefix.

Summary:
The Language Server Protocol unfortunately mandates that locations in files
be represented by line/column pairs, where the "column" is actually an index
into the UTF-16-encoded text of the line.
(This is because VSCode is written in JavaScript, which is UTF-16-native).
Internally clangd treats source files at UTF-8, the One True Encoding, and
generally deals with byte offsets (though there are exceptions).
Before this patch, conversions between offsets and LSP Position pretended
that Position.character was UTF-8 bytes, which is only true for ASCII lines.
Now we examine the text to convert correctly (but don't actually need to
transcode it, due to some nice details of the encodings).
The updated functions in SourceCode are the blessed way to interact with
the Position.character field, and anything else is likely to be wrong.
So I also updated the other accesses:
- CodeComplete needs a "clang-style" line/column, with column in utf-8 bytes.
This is now converted via Position -> offset -> clang line/column
(a new function is added to SourceCode.h for the second conversion).
- getBeginningOfIdentifier skipped backwards in UTF-16 space, which is will
behave badly when it splits a surrogate pair. Skipping backwards in UTF-8
coordinates gives the lexer a fighting chance of getting this right.
While here, I clarified(?) the logic comments, fixed a bug with identifiers
containing digits, simplified the signature slightly and added a test.
This seems likely to cause problems with editors that have the same bug, and
treat the protocol as if columns are UTF-8 bytes. But we can find and fix those.

This is a basic implementation of the "workspace/symbol" request which is

improvements could be done in the future.
The index model doesn't contain quite enough symbols for this to cover
common symbols like methods, enum class enumerators, functions in unamed
namespaces, etc. The index model will be augmented separately to achieve this.

Saving these information in the index will make the clangd life eaiser.

Summary:
Pretty straight-forward, just count all the variable declarations in the function's body, and if more than the configured threshold - do complain.
Note that this continues perverse practice of disabling the new option by default.
I'm not certain where is the balance point between not being too noisy, and actually enforcing the good practice.
If we really want to not disable this by default, but also to not cause too many new warnings, we could default to 50 or so.
But that is a lot of variables too...
I was able to find one coding style referencing variable count:
- https://www.kernel.org/doc/html/v4.15/process/coding-style.html#functions
> Another measure of the function is the number of local variables. They shouldn’t exceed 5-10, or you’re doing something wrong.

in a new algorithm in https://reviews.llvm.org/rCTE329873. It was the root of

Summary:
By converting Replacements by AtomicChange, clang-apply-replacements is able like clang-tidy to automatically cleanup and format changes.
This should permits to close this ticket: https://bugs.llvm.org/show_bug.cgi?id=35051 and attempt to follow hints from https://reviews.llvm.org/D43500 comments.

The threshold option is 'MinTypeNameLength' with default value '5'.
With MinTypeNameLength == 5 'int'/'bool' and 'const int'/'const bool'
will not be converted to 'auto', while 'unsigned' will be.

Summary:
It is possible that there will be two different instantiations of
the printer template for a given type and some tests could end up calling the
wrong (default) one. For example, it was seen in CodeCompleteTests.cpp when
printing CompletionItems that it would use the wrong printer because the default
is also instantiated in ClangdTests.cpp.
With this change, objects that were previously printed with a custom Printer now
get printed through the operator<< which is declared alongside the class.
This rule of the thumb should make it less error-prone.

LLVM_ON_WIN32 is set exactly with MSVC and MinGW (but not Cygwin) in
HandleLLVMOptions.cmake, which is where _WIN32 defined too. Just use the
default macro instead of a reinvented one.
See thread "Replacing LLVM_ON_WIN32 with just _WIN32" on llvm-dev and cfe-dev.
No intended behavior change.
