Summary:
Fix 59 `cppcoreguidelines-pro-type-member-init` lint warnings by adding `{}` value-initialization to uninitialized member fields across 17 files. This ensures all members are zero/null-initialized by default, preventing potential use of uninitialized values.
Affected files: Index.cpp, Index2Layer.cpp, IndexAdditiveQuantizer.cpp, IndexAdditiveQuantizerFastScan.h, IndexBinaryHash.h, IndexBinaryIVF.cpp, IndexFastScan.h, IndexHNSW.h, IndexIVF.h, IndexIVFAdditiveQuantizer.cpp, IndexIVFFastScan.h, IndexIVFFlat.h, IndexIVFPQ.cpp, IndexIVFPQ.h, IndexPQ.cpp, IndexPQ.h, IndexRowwiseMinMax.cpp.
Differential Revision: D100577736
Summary: Fix 136 `readability-braces-around-statements` lint warnings by adding braces to all single-line `if`, `else`, `for`, and `while` statements across 4 files: `IndexLSH.cpp` (14 issues), `IndexIVFPQ.cpp` (36 issues), `IndexPQ.cpp` (25 issues), and `VectorTransform.cpp` (61 issues). This improves code readability and prevents bugs from accidentally adding statements to unbraced blocks. Differential Revision: D100580151
Summary: Fix 172 `clang-diagnostic-shorten-64-to-32` lint warnings across 29 files by adding explicit `static_cast<int>()` or widening variable types where `size_t`/`idx_t` (64-bit) values were implicitly narrowed to `int`/`int32_t` (32-bit). The fixes fall into two categories: - **Explicit casts**: Where the receiving API requires `int` and the value is known to fit (e.g., vector dimensions, sub-quantizer counts, cluster counts, BLAS parameters) - **Type widening**: Where the variable was unnecessarily narrow (e.g., `int nprobe` → `size_t nprobe`, `int list_no` → `size_t list_no`) Differential Revision: D100588996
…tructors Summary: Fix 73 `cppcoreguidelines-special-member-functions` and `clang-diagnostic-deprecated-copy-with-user-provided-dtor` lint warnings across 32 header files by adding explicit `= default` declarations for copy/move constructors and assignment operators to 46 classes that define user-provided destructors. In C++17+, the implicit generation of copy constructors for classes with user-provided destructors is deprecated. Adding explicit `= default` preserves the existing behavior while satisfying the Rule of Five. Default constructors were also added where needed to maintain existing default-constructibility. Differential Revision: D100592061
…casts Summary: Fix 32 `facebook-avoid-non-const-global-variables` warnings by adding NOLINT comments to intentionally mutable global stats objects and configuration variables that are part of the public API (e.g., `indexIVF_stats`, `hnsw_stats`, `check_compatible_for_merge_expensive_check`). These cannot be made const as they accumulate runtime statistics and provide runtime configuration. Fix 25 `facebook-security-vulnerable-integer-implicit-cast` warnings by adding explicit `static_cast<size_t>()` to one operand before integer multiplication to prevent overflow before widening. Also fix `clang-diagnostic-switch-enum` warnings by adding missing enum cases to switch statements, and various other minor lint fixes including NOLINT for `-inl.h` includes, `ShadowingClass` fix, and `BadImplicitCast` fix.
