* filer: skip COLLATE "C" list fallback on CockroachDB CockroachDB string comparison is already byte-ordered, so wrapping the list queries in COLLATE "C" can never change result order. It reports datcollate=en_US.utf8 regardless of how the database was created, so the collation check always misfires and forces the fallback. On 22.1 and older COLLATE "C" is rejected as an invalid locale, turning every filer list query into a hard failure. Detect the backend via version() and keep the default ordering. * filer: test CockroachDB collation detection Cover the CockroachDB skip path and the locale-aware Postgres force path with go-sqlmock.
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) );
