Description:
zeroconfpy2compat 0.19.17
python-zeroconf-py2compat
This is a fork of pyzeroconf, Multicast DNS Service Discovery for Python,
originally by Paul Scott-Murphy (https://github.com/paulsm/pyzeroconf),
modified by William McBrine (https://github.com/wmcbrine/pyzeroconf),
and then further modified (off the 0.19.1 tag, the last to support Py2.7)
by Jamie Alexandre (https://github.com/learningequality/python-zeroconf).
Compatible with:
Bonjour
Avahi
Compared to some other Zeroconf/Bonjour/Avahi Python packages, python-zeroconf:
isn’t tied to Bonjour or Avahi
doesn’t use D-Bus
doesn’t force you to use particular event loop or Twisted
is pip-installable
Python compatibility
CPython 2.7, 3.3+
PyPy 2.2+ (possibly 1.9-2.1 as well)
PyPy3 2.4+
Versioning
This project’s versions follow the following pattern: MAJOR.MINOR.PATCH.
MAJOR version has been 0 so far
MINOR version is incremented on backward incompatible changes
PATCH version is incremented on backward compatible changes
Status
There are some people using this package. I don’t actively use it and as such
any help I can offer with regard to any issues is very limited.
How to get python-zeroconf-py2compat?
PyPI page https://pypi.python.org/pypi/zeroconf-py2compat
GitHub project https://github.com/learningequality/python-zeroconf-py2compat
The easiest way to install python-zeroconf-py2compat is using pip:
pip install zeroconf-py2compat
How do I use it?
Here’s an example of browsing for a service:
from six.moves import input
from zeroconf import ServiceBrowser, Zeroconf
class MyListener(object):
def remove_service(self, zeroconf, type, name):
print("Service %s removed" % (name,))
def add_service(self, zeroconf, type, name):
info = zeroconf.get_service_info(type, name)
print("Service %s added, service info: %s" % (name, info))
zeroconf = Zeroconf()
listener = MyListener()
browser = ServiceBrowser(zeroconf, "_http._tcp.local.", listener)
try:
input("Press enter to exit...\n\n")
finally:
zeroconf.close()
Note
Discovery and service registration use all available network interfaces by default.
If you want to customize that you need to specify interfaces argument when
constructing Zeroconf object (see the code for details).
If you don’t know the name of the service you need to browse for, try:
from zeroconf import ZeroconfServiceTypes
print('\n'.join(ZeroconfServiceTypes.find()))
See examples directory for more.
Changelog
0.19.16
Fix issue preventing TXT record updates from ServiceBrowser
0.19.15
Track all requested broadcast interfaces in addition to those successfully attached
0.19.14
Exclude addresses starting with “169.254” from the list returned by get_all_addresses()
0.19.13
Converts some usage of assert that should likely persist if python -O is used
Breaks out interface attachment from Zeroconf.__init__ into its own method _add_interfaces
Adds corresponding behavior for removing interfaces, along the lines of how _add_interfaces functions but in reverse
Exposes new public method Zeroconf.update_interfaces which triggers add or removal of interfaces
Prevents stack trace reporting of errors that occur because the network is unreachable, errno.ENETUNREACH
Updates Zeroconf.send to accept an interface on which filter the interfaces it sends the messages on,
such that adding and removing interfaces can attempt to send add/remove messages when the interface is removed
