Installation

pip install git+https://notabug.org/tinyrabbit/gemcall.git#egg=gemcall
# unofficial package is uploaded on PyPI for convenience
pip install gemcall

Library Usage

import gemcall

response = gemcall.request(url)

# OR

response = gemcall.request(url, clientcert, clientkey)

while True:
    buf = response.read()
    if len(buf) > 0:
        sys.stdout.buffer.write(buf)
    else:
        break

response.discard()

The gemcall.Response object has the following values:

• serverpubkey: the public key part of the server certificate (the ONLY relevant part in TOFU certificate validation).
• responsecode: the response code from the server.
• meta: the rest of the header.

The method read() should be used to get content from the response object. It takes an argument 'bufsize', which is how many bytes it will read at most. This defaults to 4096.

When you are done reading the response you should use the discard() method to close all file handles and sockets the Response object is handling.
