ResourceWarning: Enable tracemalloc to get the object allocation traceback

[josephernest]

Hi there,

Do you know what could be the reason for this message:

D:\bottle.py:2269: ResourceWarning: unclosed file <_io.BufferedReader name='D:\\test.webm'>
  func()
ResourceWarning: Enable tracemalloc to get the object allocation traceback
wsgiref\handlers.py:183: ResourceWarning: unclosed file <_io.BufferedReader name='D:\\test.webm'>
ResourceWarning: Enable tracemalloc to get the object allocation traceback

when I serve a HTML page containing

?

The video is loading successfully, but I'd like to remove this warning message if possible.

Thanks!

All the best

Have you tried enable memory tracing through tracemalloc as proposed in the warning message? Could you provide some minimal example code reproducing this issue?

If you are using bottle.static_file() to send files, then that should not happen and I cannot reproduce the issue with a recent version of bottle. Please provide more context, e.g. the ouput of tracemalloc and the exact version of Bottle in use, as well as the core that serves files.
