Aravind Ramesh 9c932816cf db_stress: db_stress segmentation fault (#9219 ) Summary: db_stress asserts/seg-faults with below command (on debug and release builds) ``` "rm -rf /tmp/rocksdbtest*; db_stress --ops_per_thread=1000 --reopen=5" ======================================= Error opening unique id file for append: IO error: No such file or directory: While open a file for appending: /tmp/rocksdbtest-0/dbstress/.unique_ids: No such file or directory Choosing random keys with no overwrite Creating 2621440 locks Starting continuous_verification_thread 2021/11/15-08:46:49 Initializing worker threads 2021/11/15-08:46:49 Starting database operations 2021/11/15-08:46:49 Reopening database for the 1th time WARNING: prefix_size is non-zero but memtablerep != prefix_hash DB path: [/tmp/rocksdbtest-0/dbstress] Segmentation fault ======================================= ``` StressTest() constructor deletes the directory "dbstress" because the option --destroy_db_initially is true by default in db_stress. This Seg fault happens on a new database, UniqueIdVerifier's constructor tries to read the ".unique_ids" file, if the file is not present, ReopenWritableFile() tries to create .unique_ids file, but fails as the directory db_stress is not available. The data_file_writer_ is set as an invalid(null) pointer and in subsequent calls (~UniqueIdVerifier() and UniqueIdVerifier::Verify()) it accesses this null pointer and crashes. This patch creates db_stress directory if it is missing, so the .unique_ids file is created.
