+This extension was generated by the Extension Wizard at
+http://ted.mielczarek.org/code/mozilla/extensionwiz/ .
+This extension is compatible only with Firefox 1.5 and
+above. Most of the files in this package are based on
+the 'helloworld' extension from the Mozillazine Knowledge Base.
+
+You can build an XPI for installation by running the
+build.sh script located in this folder. For development
+you should do the following:
+ 1. Unzip the entire contents of this package to somewhere,
+ e.g, c:\dev or /home/user/dev
+ 2. Put the full path to the folder (e.g. c:\dev\bonjour4firefox on
+ Windows, /home/user/dev/bonjour4firefox on Linux) in a file named
+ bonjour4firefox@apple.com and copy that file to
+ [your profile folder]\extensions\
+ 3. Restart Firefox.
+
+For more information, see the Mozillazine Knowledge Base:

+Building the Bonjour Firefox Extension on Windows
+
+There is a Visual Studio 2005 project file that will build the extension correctly as long as the Visual Studio environment is setup correctly. This code was built against the 1.9 version of the XULRunner SDK. The Visual Studio environment should be modified to add the include and lib paths of the XULRunner SDK. Specifically, the following include paths should be added to VC++ include directories:
+
+…\xulrunner-sdk\include\xpcom
+…\xulrunner-sdk\include\nspr
+…\xulrunner-sdk\include\string
+…\xulrunner-sdk\include\pref
+…\xulrunner-sdk\sdk\include
+
+The following path should be added to VC++ lib directories:
+
+…\xulrunner-sdk\lib
+
+After the code has been built, it can be installed like any other Firefox extension. Please consult Firefox extension documentation for more information on how to package and install Firefox extensions.

+ // DNSServer and creates identical cache entries (perhaps through records in Additional records).
+ // Now if the first one expires and tries to pick the new DNSServer (the original DNSServer
+ // is not responding) we will find cache entries corresponding to both DNSServers.

+ // AnswerQuestionsForDNSServerChanges to deliver the ADD event. This case happens when a
+ // question picks a DNS server for which AnswerNewQuestion could not deliver an answer even
+ // though there were potential cache entries but DNSServer did not match. Now when we
+ // pick a new DNSServer, those cache entries may answer this question.
+ //

+ // the old cache entries to point to the new DNSServer and the caller is expected to
+ // do a purge or reconfirm to delete or validate the RDATA. We don't need to do anything
+ // special for delivering ADD events, as it should have been done/will be done by

+
+// Sleep Proxy Server Property Encoding
+//
+// Sleep Proxy Servers are advertised using a structured service name, consisting of four
+// metrics followed by a human-readable name. The metrics assist clients in deciding which
+// Sleep Proxy Server(s) to use when multiple are available on the network. Each metric
+// is a two-digit decimal number in the range 10-99. Lower metrics are generally better.
+//
+// AA-BB-CC-DD Name
+//
+// Metrics:
+//
+// AA = Intent
+// BB = Portability
+// CC = Marginal Power
+// DD = Total Power
+//
+//
+// ** Intent Metric **
+//
+// 20 = Dedicated Sleep Proxy Server -- a device, permanently powered on,
+// installed for the express purpose of providing Sleep Proxy Service.
+//
+// 30 = Primary Network Infrastructure Hardware -- a router, DHCP server, NAT gateway,
+// or similar permanently installed device which is permanently powered on.
+// This is hardware designed for the express purpose of being network
+// infrastructure, and for most home users is typically a single point
+// of failure for the local network -- e.g. most home users only have
+// a single NAT gateway / DHCP server. Even though in principle the
+// hardware might technically be capable of running different software,
+// a typical user is unlikely to do that. e.g. AirPort base station.
+//
+// 40 = Primary Network Infrastructure Software -- a general-purpose computer
+// (e.g. Mac, Windows, Linux, etc.) which is currently running DHCP server
+// or NAT gateway software, but the user could choose to turn that off
+// fairly easily. e.g. iMac running Internet Sharing
+//
+// 50 = Secondary Network Infrastructure Hardware -- like primary infrastructure
+// hardware, except not a single point of failure for the entire local network.
+// For example, an AirPort base station in bridge mode. This may have clients
+// associated with it, and if it goes away those clients will be inconvenienced,
+// but unlike the NAT gateway / DHCP server, the entire local network is not
+// dependent on it.
+//
+// 60 = Secondary Network Infrastructure Software -- like 50, but in a general-
+// purpose CPU.
+//
+// 70 = Incidentally Available Hardware -- a device which has no power switch
+// and is generally left powered on all the time. Even though it is not a
+// part of what we conventionally consider network infrastructure (router,
+// DHCP, NAT, DNS, etc.), and the rest of the network can operate fine
+// without it, since it's available and unlikely to be turned off, it is a
+// reasonable candidate for providing Sleep Proxy Service e.g. Apple TV,
+// or an AirPort base station in client mode, associated with an existing
+// wireless network (e.g. AirPort Express connected to a music system, or
+// being used to share a USB printer).
+//
+// 80 = Incidentally Available Software -- a general-purpose computer which
+// happens at this time to be set to "never sleep", and as such could be
+// useful as a Sleep Proxy Server, but has not been intentionally provided
+// for this purpose. Of all the Intent Metric categories this is the
+// one most likely to be shut down or put to sleep without warning.
+// However, if nothing else is availalable, it may be better than nothing.
+// e.g. Office computer in the workplace which has been set to "never sleep"
+//
+//
+// ** Portability Metric **
+//
+// Inversely related to mass of device, on the basis that, all other things
+// being equal, heavier devices are less likely to be moved than lighter devices.
+// E.g. A MacBook running Internet Sharing is probably more likely to be
+// put to sleep and taken away than a Mac Pro running Internet Sharing.
+// The Portability Metric is a logarithmic decibel scale, computed by taking the
+// (approximate) mass of the device in milligrammes, taking the base 10 logarithm
+// of that, multiplying by 10, and subtracting the result from 100:
+//
+// Portability Metric = 100 - (log10(mg) * 10)
+//
+// The Portability Metric is not necessarily computed literally from the actual
+// mass of the device; the intent is just that lower numbers indicate more
+// permanent devices, and higher numbers indicate devices more likely to be
+// removed from the network, e.g., in order of increasing portability:
+//
+// Mac Pro < iMac < Laptop < iPhone
+//
+// Example values:
+//
+// 10 = 1 metric tonne
+// 40 = 1kg
+// 70 = 1g
+// 90 = 10mg
+//
+//
+// ** Marginal Power and Total Power Metrics **
+//
+// The Marginal Power Metric is the power difference between sleeping and staying awake
+// to be a Sleep Proxy Server.
+//
+// The Total Power Metric is the total power consumption when being Sleep Proxy Server.
+//
+// The Power Metrics use a logarithmic decibel scale, computed as ten times the
+// base 10 logarithm of the (approximate) power in microwatts:
+//
+// Power Metric = log10(uW) * 10
+//
+// Higher values indicate higher power consumption. Example values:
+//
+// 10 = 10 uW
+// 20 = 100 uW
+// 30 = 1 mW
+// 60 = 1 W
+// 90 = 1 kW

-Renamed mDNSClientAPI.h to mDNSEmbeddedAPI.h
- The name "mDNSClientAPI.h" is misleading to new developers looking at this code. The interfaces

+* DNSServiceSetDispatchQueue
+*
+* Allows you to schedule a DNSServiceRef on a serial dispatch queue for receiving asynchronous
+* callbacks. It's the clients responsibility to ensure that the provided dispatch queue is running.
+*
+* A typical application that uses CFRunLoopRun or dispatch_main on its main thread will
+* usually schedule DNSServiceRefs on its main queue (which is always a serial queue)
+* using "DNSServiceSetDispatchQueue(sdref, dispatch_get_main_queue());"
+*
+* If there is any error during the processing of events, the application callback will
+* be called with an error code. For shared connections, each subordinate DNSServiceRef
+* will get its own error callback. Currently these error callbacks only happen
+* if the mDNSResponder daemon is manually terminated or crashes, and the error
+* code in this case is kDNSServiceErr_ServiceNotRunning. The application must call
+* DNSServiceRefDeallocate to free the DNSServiceRef when it gets such an error code.
+* These error callbacks are rare and should not normally happen on customer machines,
+* but application code should be written defensively to handle such error callbacks
+* gracefully if they occur.
+*
+* After using DNSServiceSetDispatchQueue on a DNSServiceRef, calling DNSServiceProcessResult
+* on the same DNSServiceRef will result in undefined behavior and should be avoided.
+*
+* Once the application successfully schedules a DNSServiceRef on a serial dispatch queue using
+* DNSServiceSetDispatchQueue, it cannot remove the DNSServiceRef from the dispatch queue, or use
+* DNSServiceSetDispatchQueue a second time to schedule the DNSServiceRef onto a different serial dispatch
+* queue. Once scheduled onto a dispatch queue a DNSServiceRef will deliver events to that queue until
+* the application no longer requires that operation and terminates it using DNSServiceRefDeallocate.
+*
+* service: DNSServiceRef that was allocated and returned to the application, when the
+* application calls one of the DNSService API.
+*
+* queue: dispatch queue where the application callback will be scheduled
+*
+* return value: Returns kDNSServiceErr_NoError on success.
+* Returns kDNSServiceErr_NoMemory if it cannot create a dispatch source
+* Returns kDNSServiceErr_BadParam if the service param is invalid or the
+* queue param is invalid

-Renamed mDNSClientAPI.h to mDNSEmbeddedAPI.h

- declared in that file are ONLY appropriate to single-address-space embedded applications.
- For clients on general-purpose computers, the interfaces defined in dns_sd.h should be used.
-
-Revision 1.16 2004/09/16 18:49:34 shersche
-Remove the XP SP2 check before attempting to manage the firewall. There is a race condition in the SP2 updater such that upon first reboot after the upgrade, mDNSResponder might not know that it is running under SP2 yet. This necessitates a second reboot before the firewall is managed. Removing the check will cause mDNSResponder to try and manage the firewall everytime it boots up, if and only if it hasn't managed the firewall a previous time.

-<rdar://problem/4455038> Bonjour For Windows takes 90 seconds to start. This was caused by a bad interaction between the VirtualPC check, and the removal of the WMI dependency. The problem was fixed by: 1) checking to see if WMI is running before trying to talk to it. 2) Retrying the VirtualPC check every 10 seconds upon failure, stopping after 10 unsuccessful tries.

To Do:
- Get unicode name of machine for nice name instead of just the host name.

-<rdar://problem/4455038> Bonjour For Windows takes 90 seconds to start. This was caused by a bad interaction between the VirtualPC check, and the removal of the WMI dependency. The problem was fixed by: 1) checking to see if WMI is running before trying to talk to it. 2) Retrying the VirtualPC check every 10 seconds upon failure, stopping after 10 unsuccessful tries.

-Added support for IPv6 (v4 & v6, v4-only, v6-only, AAAA over v4, etc.). Added support for DNS-SD
-InterfaceID<->Interface Index mappings. Added support for loopback usage when no other interfaces
-are available. Updated unlock signaling to no longer require timenow - NextScheduledTime to be >= 0
-(it no longer is). Added unicast-capable detection to avoid using unicast when there is other mDNS
-software running on the same machine. Removed unneeded sock_XtoY routines. Added support for

-Removed legacy port 53 support as it is no longer needed.
-
-Revision 1.9 2003/08/20 06:21:25 bradley
-Updated to latest internal version of the mDNSWindows platform layer: Added support
-for Windows CE/PocketPC 2003; re-did interface-related code to emulate getifaddrs/freeifaddrs for
-restricting usage to only active, multicast-capable, and non-point-to-point interfaces and to ease
-the addition of IPv6 support in the future; Changed init code to serialize thread initialization to
-enable ThreadID improvement to wakeup notification; Define platform support structure locally to
-allow portable mDNS_Init usage; Removed dependence on modified mDNSCore: define interface ID<->name
-structures/prototypes locally; Changed to use _beginthreadex()/_endthreadex() on non-Windows CE
-platforms (re-mapped to CreateThread on Window CE) to avoid a leak in the Microsoft C runtime;
-Added IPv4/IPv6 string<->address conversion routines; Cleaned up some code and added HeaderDoc.
