pulsectl-asyncio's Issues

time_t portability

For your FFI you define timeval as follows:

class timeval(c.Structure):
    _fields_ = [
        ('tv_sec', c.c_longlong),
        ('tv_usec', c.c_long),
    ]

This is, unfortunately not portable as tv_sec is of type time_t which may also be c_long (as it is in my case), and then overflowing like this later on:

  File "/usr/lib/python3.6/selectors.py", line 445, in select
    fd_event_list = self._epoll.poll(timeout, max_ev)
OverflowError: timestamp too large to convert to C _PyTime_t

because the upper bytes are undefined. Forcing c_long instead helps in my case but i suspect this is also not more portable - even though one might get away with it...

Connecting with Pulse Audio from service

Hi! I'm using the library to create an Ubuntu service that connects with Pulse Audio and automatically ducks music applications when something else is running.

When I run the script, it runs perfectly, but when I run it as a service, it fails to connect with the Pulse Audio server. Any ideas why please? This is the traceback:

Mar 08 21:52:11 nitro python[47240]: Traceback (most recent call last):

Mar 08 21:52:11 nitro python[47240]: pulsectl.pulsectl.PulseError: Failed to connect to pulseaudio server

This is my service:

[Unit]
Description=Auto-ducker
After=multi-user.target
[Service]
Type=simple
Restart=always
ExecStart=/path/to/venv/bin/python /path/to/main.py
[Install]
WantedBy=multi-user.target

I have tried:

  • Specifying the server manually. When I run pulse.server_info(), the server name shows as 'pulseaudio'. When I specify the server (async with pulsectl_asyncio.PulseAsync('volume-increaser', server='pulseaudio') as pulse:), it fails to connect.
  • Running the service with User=nicholas and Group=nicholas, my user and user group.

In both cases, the server fails to connect to the pulseaudio server.

not existing pulsectl versions in setup.cfg

guess, it should be:

[options]
packages = pulsectl_asyncio
python_requires = >=3.6
install_requires =
    pulsectl >=23.5.0,<=23.5.1
include_package_data = True

or currently:

[options]
packages = pulsectl_asyncio
python_requires = >=3.6
install_requires =
    pulsectl >=23.5.0,<=23.5.2
include_package_data = True

in setup.cfg?

else it can't be satisfied, it think...

Deprecation of module inspect on python 3.11
