Michal Gorny a81de445c1 [cmake] Support running extra clang tool tests without static analyzer
Support running the extra clang tool tests when the static analyzer
is disabled. Disable the relevant clang-tidy tests and one include-fixer
test that require it to work.

Previously, the tests were disabled entirely with
CLANG_ENABLE_STATIC_ANALYZER being false. Now, the tests are being
enabled and the relevant tests are excluded and marked unsupported
appropriately.

In order to disable clang-tidy tests, the whole test directory is added
to the exclude lists, to avoid having to explicitly add 'REQUIRES' line
to every single test. If the other solution is preferable, I can update
the patch.

The yamldb_plugin include-fixer test is also updated to be disabled
without static analyzer. It fails in that case because clang is not
outputting a replacement suggestion -- but I don't know the exact
reason why it does not do that.

Sam McCall 9c5ebf7039 [include-fixer] Add fuzzy SymbolIndex, where identifier needn't match exactly.
Summary:
Add fuzzy SymbolIndex, where identifier needn't match exactly.

The purpose for this is global autocomplete in clangd. The query will be a
partial identifier up to the cursor, and the results will be suggestions.

It's in include-fixer because:

  - it handles SymbolInfos, actually SymbolIndex is exactly the right interface
  - it's a good harness for lit testing the fuzzy YAML index
  - (Laziness: we can't unit test clangd until reorganizing with a tool/ dir)

Other questionable choices:

  - FuzzySymbolIndex, which just refines the contract of SymbolIndex. This is
    an interface to allow extension to large monorepos (*cough*)
  - an always-true safety check that Identifier == Name is removed from
    SymbolIndexManager, as it's not true for fuzzy matching
  - exposing -db=fuzzyYaml from include-fixer is not a very useful feature, and
    a non-orthogonal ui (fuzziness vs data source). -db=fixed is similar though.

Sam McCall 573050e703 [include-fixer] Remove line number from Symbol identity
Summary:
Remove line number from Symbol identity.

For our purposes (include-fixer and clangd autocomplete), function overloads
within the same header should mostly be treated as a single combined symbol.

We may want to track individual occurrences (line number, full type info)
and aggregate this during mapreduce, but that's not done here.

Sam McCall b27dc2245f [include-fixer] Add usage count to find-all-symbols.
Summary:
Add usage count to find-all-symbols.

FindAllSymbols now finds (most!) main-file usages of the discovered symbols.
The per-TU map output has NumUses=0 or 1 (only one use per file is counted).
The reducer aggregates these to find the number of files that use a symbol.

The NumOccurrences is now set to 1 in the mapper rather than being inferred by
the reducer, for consistency.

The idea here is to use NumUses for ranking: intuitively number of files that
use a symbol is more meaningful than number of files that include the header.

Manuel Klimek a47515ec4a Improve include fixer's ranking by taking the paths into account.
Instead of just using popularity, we also take into account how similar the
path of the current file is to the path of the header.
Our first approach is to get popularity into a reasonably small scale by taking
log2 (which is roughly intuitive to how humans would bucket popularity), and
multiply that with the number of matching prefix path fragments of the included
header with the current file.
Note that currently we do not take special care for unclean paths containing
"../" or "./".

Haojian Wu c99f72868d [include-fixer] Support processing multiple files in one run.
Summary:
Previously, if we pass multiple files or a file pattern (e.g. /path/to/*.cc) to
include-fixer, include-fixer will apply all replacements to the first argument,
which probably causes crashes.

With this patch, include-fixer can process multiple files now.

Vim and Emacs integration are tested manually.

Haojian Wu 13d3048ced [include-fixer] Keep dot dot in SymbolInfo file paths.
Summary:
Currently, removing dot dot in header's path doesn't make include-fixer
minimize path correctly in some cases, for example, specify a relative search
path based on the build directory("-I../include/").

Besides, removing dot dot can break symbolic link directories. So don't
removing it for now.

Benjamin Kramer b53452b2b1 [include-fixer] Be smarter about inserting symbols for a prefix.
If prefix search finds something where nothing can be nested under (e.g.
a variable or macro) don't add it to the result.

This is for cases like:
header.h:
  extern int a;

file.cc:
namespace a {
  SOME_MACRO
}

We will look up a::SOME_MACRO, which doesn't have any results. Then we
look up 'a' and find something before we ever look up just 'SOME_MACRO'.
With some basic filtering we can avoid this case.

Benjamin Kramer 6b5160a369 [include-fixer] Don't insert #includes if a fatal error occurred.
This typically happens when the user didn't setup include paths correctly
and the fixer starts adding garbage includes. Avoid that. Disable the error
limit though, as we might hit that easily with missing includes and still
want to fix those cases.
