In my environment, gadwall always fails like:
C:\temp>python -m gadwall duck.db
Traceback (most recent call last):
File "C:\Program Files\Python39\lib\runpy.py", line 197, in _run_module_as_main
return _run_code(code, main_globals, None,
File "C:\Program Files\Python39\lib\runpy.py", line 87, in _run_code

cmd = Gadwall(args.filename.name)
File "C:\Program Files\Python39\lib\site-packages\gadwall.py", line 22, in __init__
self.conn = duckdb.connect(file_name)
RuntimeError: IO Error: Cannot open file "duck.db": The process cannot access the file because it is used by another process.
(Sorry, the last sentence may be wrong: it was in German, i translated it myself as i do not know how to force it to English)
I could fix this by two changes: I changed
parser.add_argument('filename', type=FileType('r'))
args = parser.parse_args()
cmd = Gadwall(args.filename.name)
to
parser.add_argument('filename')
args = parser.parse_args()
cmd = Gadwall(args.filename)
In fact, i wonder how the original code could work. But i did not find documentation of what argparse "returns" in case of type=FileType().
My environment:
Windows 10 21H2 (Build 19044.1586), 64bit
Python 3.9.6, 64bit
argparse-1.4.0
duckdb-0.3.2
gadwall-0.1.0
Kind regards,
