Summary: Plain table SSTs could crash sst_dump because of a bug in PlainTableReader that can leave table_properties_ as null. Even if it was intended not to keep the table properties in some cases, they were leaked on the offending code path. Steps to reproduce: $ db_bench --benchmarks=fillrandom --num=2000000 --use_plain_table --prefix-size=12 $ sst_dump --file=0000xx.sst --show_properties from [] to [] Process /dev/shm/dbbench/000014.sst Sst file format: plain table Raw user collected properties ------------------------------ Segmentation fault (core dumped) Also added missing unit testing of plain table full_scan_mode, and an assertion in NewIterator to check for regression. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5940 Test Plan: new unit test, manual, make check Differential Revision: D18018145 Pulled By: pdillinger fbshipit-source-id: 4310c755e824c4cd6f3f86a3abc20dfa417c5e07
