Re: [Pharo-project] Networking change in Pharo 1.2?

by Chris Muller

Just bench it: Before change: [ NetNameResolver localHostAddress ] bench " '34,000 per second.' " After change: [ NetNameResolver localHostAddress ] bench " '31 per second.' " In just looking at the reason given for making the change, it says this is to satisfy an _exceptional_ case; e.g., the case where "no network connection is available." Then I look at the new code called by #localHostAddress and becomes obvious why: isConnected "Dirty, but avoids fixing the plugin bug" [NetNameResolver addressForName: 'www.esug.org'.] on: NameLookupFailure do: [:ex| ^false]. ^true A hard-coded nslookup to 'www.esug.org' wrapped in an exception-handler? Wow! If this isn't enough, you can run the Magma test-suite to see the effect on a real-world networking application. I recommend Pharo crew revert this change and consider a different approach. - Chris On Tue, Apr 19, 2011 at 2:27 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > yes > Now do you have a description how we can reproduce your problem because the fix was fixing something. > and it would be good to understand what is the deeper problem. > Stef > > On Apr 19, 2011, at 4:20 AM, Chris Muller wrote: > >> Thank you too; it was a bruising problem I'm glad to have it identified. >> >> On Mon, Apr 18, 2011 at 12:21 PM, Marcus Denker <marcus.denker(a)inria.fr> wrote: >>> >>> On Apr 18, 2011, at 7:14 PM, Chris Muller wrote: >>> >>>>> The only change to NetNameResolver was this: >>>>> >>>>> Â Â Â Â http://code.google.com/p/pharo/issues/detail?id=1853 >>>> >>>> Reverting this change fixed it. >>>> >>> >>> >>> Thanks!

Re: [Pharo-project] Networking change in Pharo 1.2?

by Schwab,Wilhelm K

Stef, What was it fixing? There might be a better solution. I found myself trying to swim in Linux, Pharo and machines with multiple interfaces (wired and wireless) almost simultaneously. I still haven't really figured it out, but *if* #localHostAddress makes sense at all (#localHostAddresses might be more meaningful message), it should probably raise an error if there is not a unique result. #localHostAddress:ifNone:ifMany: would put the sender in control. For your problem, #localHostOrLoopBackAddress would be another option; at least the sender would be knowingly accepting the "risk" of getting the loopback address.

Coool! so it is just a matter of copying your commits to PharoOB repo and updating the confs :) or just to update the confs to get the versions from your repo.

sadly after 10 min I could not find how to integrate your work. I hate this cool UI that are just plain confusing and totally inadapted. I have no idea how to do it. I will try to find but I hate hate this $#%^&*() system.

:) No I was driving all day long yesterday and I will try to find my way in the github interface. Damien showed me how I can pull a request and merge it, so this is time to try for real.

yes Now do you have a description how we can reproduce your problem because the fix was fixing something. and it would be good to understand what is the deeper problem.
