Is there a tonel:// format for repos?

by Tim Mackinnon

Hi - I converted my project to tonel, and am looking to hook it up to my gitlab pipeline, and for older projects I had a run.st <http://run.st/> script that did: Metacello new baseline: 'WillowPagerDuty'; repository: âfiletree://../src'; load. I get a not found error when I run that, is there a new repo type for tonel eg? Metacello new baseline: 'WillowPagerDuty'; repository: 'tonel://../src'; load. Or is this the PR Esteban was working on earlier this month so that filetree can support tonel? If so, it would be very good to get this support as it makes it much easier to write generic scripts to run in CI projects without having to reference branch names to build things (as its simply the source in you git directory that you want to build locally ) Tim

What I said is that there is a (not so) "new" finalization mechanism called ephemerons implemented in the VM since some time ago, that avoids memory leaks when using weak dictionarys.

That's the "old" ipv4 primitive. The "new" ipv4/ipv6 primitive (sqResolverGetAddressInfoHostSizeServiceSizeFlagsFamilyTypeProtocol) uses getaddrinfo instead, and lets you interate over the results; this is what the SSDP package tries to do when you specify allLocalV4Addresses. It's unreliable because: 1) Finding the correct hostname can be difficult (iirc, some vm's fail the hostname prim, and always returns the fallback 'localhost') 2) It uses DNS lookups, which can both be slow, and depend on network configuration. 3) The correct domain to use when you want aggregated results over multiple interfaces (.local? nothing?) differs from platform to platform. (iirc, OSX only ever returns a single entry if adding .local) "However when I activate a second network interface, this last one returns an empty collection" I just tested on a Windows 10 machine with 6.1 release (Pharo 6.1 stable\Pharo.exe CoInterpreter VMMaker.oscog-eem.2254 uuid: 4f2c2cce-f4a2-469a-93f1-97ed941df0ad Jul 20 2017), for me the statement part := SSDPParticipant new. part allLocalV4Addresses. correctly returns 1/2/1 addresses when connecting/disconnecting to a wireless network :/ Why lookup would start to fail when you activate an interface, and stay failing after you remove it, I couldn't say, but I can say that SSDPParticipant >> hostName returning names that DNS won't resolve properly for some or another reason has been a problem I've encountered before.

Re: [Pharo-users] How to LAN feature

by HilaireFernandes

Hello, Thanks for the tip. Yep, indeed it is possible to get the information from the command line. But I need a strategy that will work on Windows too (75% of the Dr. Geo user base). I have the same problem with bitmap clipboard, I have a strategy only for linux with command line[1], may be for Mac, but I don't know for Windows.
