workspace/symbol
Summary:
Some URI schemes require a hint path to be provided, and workspace root
path seems to be a good fit.

Summary:
For completion items that would trigger include insertions (i.e. index symbols
that are not #included yet), add a visual indicator "+" before the completion
label. The inserted headers will appear in the completion detail.
Open to suggestions for better visual indicators; "+" was picked because it
seems cleaner than a few other candidates I've tried (*, #, @ ...).
The displayed header would be like a/b/c.h (without quote) or <vector> for system
headers. I didn't add quotation or "#include" because they can take up limited
space and do not provide additional information after users know what the
headers are. I think a header alone should be obvious for users to infer that
this is an include header..
To align indentation, also prepend ' ' to labels of candidates that would not
trigger include insertions (only for completions where index results are
possible).

Summary:
Adds a CodeCompleteOption to folds together compatible function/method overloads
into a single item. This feels pretty good (for editors with signatureHelp
support), but has limitations.
This happens in the code completion merge step, so there may be inconsistencies
(e.g. if only one overload made it into the index result list, no folding).
We don't want to bundle together completions that have different side-effects
(include insertion), because we can't constructo a coherent CompletionItem.
This may be confusing for users, as the reason for non-bundling may not
be immediately obvious. (Also, the implementation seems a little fragile)

Summary:
This is a small code change but vastly reduces noise in code completion results.
The intent of allowing this was to let [sc] ~ "strncpy" and [strcpy] ~ "strncpy"
however the benefits for unsegmented names aren't IMO worth the costs.
Test cases should be representative of the changes here.

Summary:
Caching is now handled by ClangdLSPServer and hidden behind the
GlobalCompilationDatabase interface. This simplifies ClangdServer.
This change also removes the SkipCache flag from addDocument,
which is now obsolete.
No behavioral changes are intended, the clangd binary still caches the
compile commands on the first read.

Sema priority
Summary:
Now we have most of Sema's code completion signals incorporated in Quality,
which will allow us to give consistent ranking to sema/index results.
Therefore we can/should stop using Sema priority as an explicit signal.
This fixes some issues like namespaces always having a terrible score.
The most important missing signals are:
- Really dumb/rarely useful completions like:
SomeStruct().^SomeStruct
SomeStruct().^operator=
SomeStruct().~SomeStruct()
We already filter out destructors, this patch adds injected names and
operators to that list.
- type matching the expression context.
Ilya has a plan to add this in a way that's compatible with indexes
(design doc should be shared real soon now!)

Summary:
This signal is considered a relevance rather than a quality signal because it's
dependent on the query (the fact that it's completion, and implicitly the query
context).
This is part of the effort to reduce reliance on Sema priority, so we can have
consistent ranking between Index and Sema results.

Summary:
This adds more symbols to the index:
- member variables and functions
- enum constants in scoped enums
The code completion behavior should remain intact but workspace symbols should
now provide much more useful symbols.
Other symbols should be considered such as the ones in "main files" (files not
being included) but this can be done separately as this introduces its fair
share of problems.

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:
They cause lots of deserialization and are not actually used.
The ParsedAST accessor that previously returned those was renamed from
getTopLevelDecls to getLocalTopLevelDecls in order to avoid
confusion.
This change should considerably improve the speed of findDefinition
and other features that try to find AST nodes, corresponding to the
locations in the source code.

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.

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
for the problem.

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
crashes, e.g. when parsing comments.
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.

Summary:
To fix a crash in code completion that occurrs when reading doc
comments from files that were updated after the preamble was
computed. In that case, the files on disk could've been changed and we
can't rely on finding the comment text with the same range anymore.
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
we're aware of.

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:
Previous implementation used to extract brief text from doxygen comments.
Brief text parsing slows down completion and is not suited for
non-doxygen comments.
This commit switches to providing comments that mimic the ones
originally written in the source code, doing minimal reindenting and
removing the comments markers to make the output more user-friendly.
It means we lose support for doxygen-specific features, e.g. extracting
brief text, but provide useful results for non-doxygen comments.
Switching the doxygen support back is an option, but I suggest to see
whether the current approach gives more useful results.

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).

Summary:
This patch adds index support for GoToDefinition -- when we don't get the
definition from local AST, we query our index (Static&Dynamic) index to
get it.
Since we currently collect top-level symbol in the index, it doesn't support all
cases (e.g. class members), we will extend the index to include more symbols in
the future.
