Re: [Pharo-project] [squeak-dev] NetNameResolver/ifconfig/interfaces

by Schwab,Wilhelm K

John, Prompts are bad, at least if they are mandatory. There should be a way to provide a block that takes as argument a collection of the available interfaces; variatiants of the method could do first/last or (hopefully) guess the correct interface as a lot of software seems to do.

It's unclear if reverting the new/old socket stuff in Pharo is a good idea, or if we just adjust things a bit in the name lookup that would solve things. There are two questions to resolve (1) Do we want to return an IPV4 address from the network lookup? or an IPV6 address? (2) What do we do when we have 2 or more active IP interfaces on the machine, prompt for which one to use? Pick one at random, use the first or last one? If the community can decide what to do, then we can propose a solution. So how it works. NetNameResolver localHostAddress fe80::21c:42ff:fe00:9%en5(otter-2.local),0(0) Gah... what's that? Well the interface is: en5: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::21c:42ff:fe00:9%en5 prefixlen 64 scopeid 0x8 inet 10.37.129.2 netmask 0xffffff00 broadcast 10.37.129.255 ether 00:1c:42:00:00:09 media: autoselect status: active supported media: autoselect Thus it's giving me an IPV6 address. The chore is more complicated that one would care to see. I see Microsoft had a hand in defining the spec. So it first asks the gethostname for the name of the host. As an example my macbook pro has Otter-2.local which is what [otter-2:~] johnmci% hostname Otter-2.local That's a bonjour assigned name since if I do [otter-2:~] johnmci% nslookup Otter-2.local Server: 192.168.1.7 Address: 192.168.1.7#53 ** server can't find Otter-2.local: NXDOMAIN Then we are off to: getnameinfo which returns a chain of IPV4 and IPV6 address that Otter-2.local would resolve to. In this case there are six address, broken in to IPV6 and IPV4 fe80::21c:42ff:fe00:8%en4(otter-2.local),0(0)-inet6-stream-tcp fe80::21c:42ff:fe00:9%en5(otter-2.local),0(0)-inet6-stream-tcp fe80::21b:63ff:fe02:d2db%en1(otter-2.local),0(0)-inet6-stream-tcp 10.211.55.2(10.211.55.2),0(0)-inet4-stream-tcp 10.37.129.2(10.37.129.2),0(0)-inet4-stream-tcp 192.168.1.141(192.168.1.141),0(0)-inet4-stream-tcp So looks kinda random, but it's not. It's defined by Microsoft & committee etc. in http://www.faqs.org/rfcs/rfc3484.html The objective is to sort the list into some order. I must say you can't actually tell from reading the docs, and things over the past decade have changed. So I refer to some cheat sheets that *might* be correct. Now the macbook pro in this case uses 192.168.1.141 as the assigned tcp/ip address from our internal DHCP server. The 10.211.55.2 is a parallels shared network adaptor and 10.37.129.2 is the parallels host-only network adaptor. All three interfaces show as active, and if you consider the 'ifconfig -a' below you would be hard pressed to determine which interface is the one facing the company intranet.

How helpful. So how do we know *which* is the proper address to use? Well no idea! However let's see what the API does. NetNameResolver class>> addressesForName: hostName | adresses | adresses := SocketAddressInformation forHost: hostName service: '' flags: 0 addressFamily: 0 socketType: SocketAddressInformation socketTypeStream protocol: SocketAddressInformation protocolTCP. ^adresses Now I can make it return just IPV4 address by doing: NetNameResolver class>> addressesForName: hostName | adresses | adresses := SocketAddressInformation forHost: hostName service: '' flags: 0 addressFamily: SocketAddressInformation addressFamilyINET4 socketType: SocketAddressInformation socketTypeStream protocol: SocketAddressInformation protocolTCP. ^adresses which then NetNameResolver localHostAddress gives: 10.37.129.2(10.37.129.2),0(0) I can also supply a service number string say SSH '22' that give back 10.37.129.2(10.37.129.2),22(ssh) since ssh is binding on all interfaces that's valid. Technically the getnameinfo gives back three address but again the code below grabs the first one which according to the rfc3484 is more likely to be the correct answer. addressForName: hostName "NetNameResolver addressForName: 'impara.de' " "NetNameResolver addressForName: 'localhost' " "NetNameResolver addressForName: '127.0.0.1' " | addresses | self useOldNetwork ifTrue: [^self oldAddressForName: hostName]. addresses := self addressesForName: hostName. ^addresses ifEmpty: [nil] ifNotEmpty: [addresses first socketAddress] But grabbing the first one doesn't meet people's expectations of correctness, however we just don't have enough information to decide *what* is correct. Now some people say OH let's return the en0 one because that is correct? Really how do you know? On my computer en0 is ethernet, but since I'm using wireless then en1 is the correct one. Obviously I could look in the list of IPV6 address find the LOWEST en# value, then grab the IPV4 entry. This would assume I check for the fact that the IPV6 interface has an IPV4 address and the sort order for the IPV6 is the same as for the IPV4. Gee that sounds ok? Well it's not, when for example I tether my MacBook Pro to my iPhone and abuse my privilege to move data over the cellular carrier, ah sorry you USA ATT folks, then the interface is: en6: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::226:8ff:fe72:5aa%en6 prefixlen 64 scopeid 0x9 inet 192.168.20.2 netmask 0xffffff00 broadcast 192.168.20.255 ether 00:26:08:72:05:aa media: 10baseT/UTP status: active supported media: 10baseT/UTP which fails the test that the lowest active en# is the one we want to use. 10.37.129.2(10.37.129.2),0(0)-inet4-stream-tcp 10.211.55.2(10.211.55.2),0(0)-inet4-stream-tcp 192.168.20.2(192.168.20.2),0(0)-inet4-stream-tcp) So the question is what would the community like to see happen.

[Pharo-project] Use of #asMorph

by Igor Stasenko

Hello, lists i'd like to ask an intricate question. Suppose that your morph acts as a container, which needs to hold an items, retrieved from a model object. A model's elements could be any object, and may choose to represent them in a way they like it. So, for instance, if we taking a list, the list elements is represented by a morphs not simple strings. Now, a question: is it fine to use #asMorph as a message to 'convert' a model's item to a morph, which then can be used to reflect given item in list? I.e. something like: model itemsDo: [:item | self addMorph: item asMorph ] In this way, a list is built from morphs, and each list item choosing by itself, what morph should be used to represent itself in a list. But by saying A, we usually need to say B: an object could choose different representation depending on container's properties: model itemsDo: [:item | self addMorph: (item asMorphIn: self) ] So, for example, a compiled method, could choose to represent itself in a list as a simple string with own selector, while in text editor it could choose to display own source code. What you would do in such case? -- Best regards, Igor Stasenko AKA sig.
