When run on Windows, flashproxy-reg-email produces the following error:

Failed to register: [Errno 185090050] _ssl.c:340: error:0B084002:x509 certific
ate routines:X509_load_cert_crl_file:system lib

This is due to the use of tempfile.NamedTemporaryFile? to store a TLS certificate. On windows NT or later, the temporary file cannot be reopened while still in use. See the tempfile module documentation at

I think this would be best fixed using the code related to ticket #7016 (running as a managed proxy), to take
into account TOR_PT_STATE_LOCATION. Should I wait until the code for that ticket is merged into the main repo,
or just clone and work from there?

I have a fix for this at, branch ticket#7271.    

I use mkstemp and close the file when done.

Priority: minormajor looks good. I'm guessing that because of the following, there is an exception at runtime unless we use the file descriptor functions?

comment:4 Changed 5 years ago by aallai

mkstemp returns a file descriptor instead of a file object, I had misread the doc. We could use os.fdopen on it, and then use the regular file functions.

Thanks, I squashed the two commits and merged them.
