Testy script that validates the table has failed under snapshot ID snap-001b76b801cc0b334
Traceback (most recent call last): File "/srv/testy/wiredtiger/bench/workgen/validate_mirror_tables.py", line 142, in <module> main(sys.argv[1:]) File "/srv/testy/wiredtiger/bench/workgen/validate_mirror_tables.py", line 116, in main mirrors = get_mirrors(db_dir, db_files) File "/srv/testy/wiredtiger/bench/workgen/validate_mirror_tables.py", line 66, in get_mirrors mirror_filename = get_mirror_file(db_dir, f'table:{filename}') File "/srv/testy/wiredtiger/bench/workgen/validate_mirror_tables.py", line 87, in get_mirror_file metadata = c[filename] File "/srv/testy/wiredtiger/build/lang/python/wiredtiger/swig_wiredtiger.py", line 328, in __getitem__ raise KeyError KeyError
Error has happened here within the code:
# Get the mirror for the specified file by examining the file's metadata. Mirror names # are stored in the 'app_metadata' by workgen when mirroring is enabled. If the file has # a mirror, the name of the mirror is returned. Otherwise, the function returns None. def get_mirror_file(db_dir, filename): connection = wiredtiger_open(db_dir, 'readonly') session = connection.open_session() c = session.open_cursor('metadata:', None, None) metadata = c[filename] c.close() result = re.findall('app_metadata="([^"]*)"', metadata) mirror = None if result: app_metadata = dict((a.strip(), b.strip()) for a, b in (element.split('=') for element in result[0].split(','))) if app_metadata.get('workgen_dynamic_table') == 'true' and \ app_metadata.get('workgen_table_mirror') != None : mirror = app_metadata['workgen_table_mirror'] mirror = mirror.split(':')[1] session.close() connection.close() return mirror
The problem seems to be that we are not able to find the specific mirror file within the directory. A quick scan of the data directory shows that all the mirror tables exist.
