Summary: This diff contains trivial fixes for 6 scan-build warnings: **db/c_test.c** `db` variable is never read. Removed assignment. scan-build report: http://home.fburl.com/~sugak/latest20/report-9b77d2.html#EndPath **db/db_iter.cc** `skipping` local variable is assigned to false. Then in the next switch block the only "non return" case assign `skipping` to true, the rest cases don't use it and all do return. scan-build report: http://home.fburl.com/~sugak/latest20/report-13fca7.html#EndPath **db/log_reader.cc** In `bool Reader::SkipToInitialBlock()` `offset_in_block` local variable is assigned to 0 `if (offset_in_block > kBlockSize - 6)` and then never used. Removed the assignment and renamed it to `initial_offset_in_block` to avoid confusion. scan-build report: http://home.fburl.com/~sugak/latest20/report-a618dd.html#EndPath In `bool Reader::ReadRecord(Slice* record, std::string* scratch)` local variable `in_fragmented_record` in switch case `kFullType` block is assigned to false and then does `return` without use. In the other switch case `kFirstType` block the same `in_fragmented_record` is assigned to false, but later assigned to true without prior use. Removed assignment for both cases. scan-build reprots: http://home.fburl.com/~sugak/latest20/report-bb86b0.html#EndPath http://home.fburl.com/~sugak/latest20/report-a975be.html#EndPath **table/plain_table_key_coding.cc** Local variable `user_key_size` is assigned when declared. But then in both places where it is used assigned to `static_cast<uint32_t>(key.size() - 8)`. Changed to initialize the variable to the proper value in declaration. scan-build report: http://home.fburl.com/~sugak/latest20/report-9e6b86.html#EndPath **tools/db_stress.cc** Missing `break` in switch case block. This seems to be a bug. Added missing `break`. Test Plan: Make sure all tests are passing and scan-build does not report 'Dead assignment' and 'Dead initialization' bugs. ```lang=bash % make check % make analyze ``` Reviewers: meyering, igor, kradhakrishnan, sdong Reviewed By: sdong Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D33795 |
