* filer: escape LIKE wildcards in SQL list prefixes ListDirectoryPrefixedEntries bound prefix+"%" straight into a LIKE clause, so '_' and '%' in object names (e.g. Langfuse keys like call_03_...) acted as wildcards: wrong results and a ~40x slower range scan because (dirhash, name) can no longer be narrowed. Escape '!'/'%'/'_' in the prefix and declare ESCAPE '!' in the generated list SQL so every abstract_sql backend (mysql, mysql2, postgres, postgres2, sqlite) matches literally with identical semantics. '!' is used instead of '\' because SQLite shares SqlGenMysql but would reject the MySQL-style '\\' literal, and '\' would still need escaping itself. * filer: escape LIKE wildcards in YDB list prefixes Same wildcard-in-prefix bug as the abstract_sql backends: YQL LIKE treated '_' and '%' in the prefix as wildcards. Apply the shared LikePattern helper and declare ESCAPE '!' (YQL allows any escape char except '%', '_' and '\'). * test: cover literal '_'/'%'/'!' prefixes in sqlite filer listing End-to-end regression test through SqliteStore against a real database; runs in CI under the sqlite build tag.
1. create "seaweedfs" database export PGHOME=/Library/PostgreSQL/10 $PGHOME/bin/createdb --username=postgres --password seaweedfs 2. create "filemeta" table $PGHOME/bin/psql --username=postgres --password seaweedfs CREATE TABLE IF NOT EXISTS filemeta ( dirhash BIGINT, name VARCHAR(65535), directory VARCHAR(65535), meta bytea, PRIMARY KEY (dirhash, name) );
