Hi, this is an awesome project! I really want to do some contributions. After git clone, I installed all the requirements and then started to run the test cases. But sadly, they were totally failed.

This is an example error.

Hi @leeexyz you probably forgot to run build.py to build Cython extensions, let me know if it helps, I appreciate your interest :)

@frnkvieira Thanks for your quick reply :) After built, I still got many errors.

I am not sure if the SSL handshake error is related to pyenv.

Can you please show me the value of (host, port) at the last stack trace ? (This line: "sock.connect((host, port))")... You can put a breakpoint there or add a print statement right before this line to get the value. Many thanks!

@frnkvieira I printed some values as follows.

+1, I got the same error

I got the same error too. In my system, I have to 'pip install cython' to make 'build.py' run, and it failed.

$ python --version; uname -a

If that helps.

That's one of the reasons I created #85

In MacOS (with a few other cases) the socket library raises a few different exceptions that I was unaware of, I think I got them fixed, I'll push an update tonight and update here so you guys can check it out. Many thanks!

I think this is issue is gone in master branch but I'll work more on it by Monday, I appreciate your feedback on this, thanks !

@frnkvieira Even installed the patch, I still encounter this issue.

Here are some tries I made to reproduce the issue.

First, I added two line before and after sock.connect((host, port)).

# vibora.utils.wait_server_available
            print("connecting:", (host, port))
            sock.connect((host, port))
            print("connected")

1. Runing the server directly, it was ok.

Python 3.6.5 (default, Jun 29 2018, 23:22:22)

connected
# Vibora (0.0.7) # http://127.0.0.1:5000
^C>>> 

2. Runing the test client, but it cannot connect to port 52652. The wired thing is the port was listening. localhost:52652 (LISTEN)

>>> app.test_client()
connecting: ('127.0.0.1', 52652)
....... keep printing

python  73617 tuisku   17u  IPv4 0x17a6fed7972984b5      0t0  TCP localhost:52652 (LISTEN)

3. And when the timeout error occurred, I tried to connect it manually.

Finally, I thought it should be the server is not ready yet. So, I added a sleep statement before wait_server_available. Surprisingly, it worked!

# vibora.Vibora.run
        if not sock:
            import time
            time.sleep(1)
            wait_server_available(host, port)

>>> from vibora import Vibora
>>> app = Vibora()
>>> app.test_client()
connecting: ('127.0.0.1', 53329)
connected
<vibora.client.session.Session object at 0x1052edf20>

Hope this is useful. :)
