[Pharo-project] [ANN] Magma 1.2
by Chris Muller April 20, 2011

April 20, 2011

Magma 1.2 is now finally released for Squeak 4.2, Pharo 1.1 and Pharo 1.2. This new release offers improved performance thanks to minimizing the problem associated with finalization, as well as avoiding Squeak's slow become except once every 30 seconds. See http://wiki.squeak.org/squeak/6163 for release-notes details. I just went through all of the wiki pages and fixed / updated several of them, including new, clean, one-click installation scripts for for Pharo: http://wiki.squeak.org/squeak/2657 Squeak users may install with one-click directly from the SqueakMap Catalog user-interface. I hope Pharo will consider bringing this back into a future version; SqueakMap already has several projects that load from Metacello. I also realized several of Magma's special capabilities have been undocumented. I've now documented them. http://wiki.squeak.org/squeak/6164 This release is, exactly, one year since Magma 1.1, thank you for your patience. As before, support for Magma is described at: http://wiki.squeak.org/squeak/5818

[Pharo-project] Announcer methods are bloated
by DougEdmunds April 20, 2011

April 20, 2011

If Announcements are newly added to core (discussion at http://forum.world.st/Announcements-in-core-images-tc3188286.html) why not start with a trimmed down set of methods? Why start with bloat? Announcer has these two core methods: 1) subscribe:do 2) subscribe:send:to: are fine. There is no need for 3) on:do (just calls 1) 4) on:send:to: (just calls 2) 5) when:do (also justs calls 1) -- View this message in context: http://forum.world.st/Announcer-methods-are-bloated-tp3461131p3461131.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Vanessa and Alexandre show us Hapao, an innovative test coverage tool implemented in the Pharo Smalltalk programming language. You will see how they analyse the ProfStef interactive tutorial, increase test coverage and commit their contribution to SqueakSource. http://www.pharocasts.com/2011/04/test-coverage-with-hapao.html -- Laurent Laffont - @lolgzs Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/ Developer group: http://cara74.seasidehosting.st

[Pharo-project] Networking change in Pharo 1.2?
by Chris Muller April 19, 2011

April 19, 2011

I was able to work on getting Magma 1.2 going in Pharo. It was quite easy to get the code loaded and functioning in Pharo 1.1.1, Pharo 1.2, and Pharo 1.3. But something seems to have changed in Pharo's networking from 1.1.1 to 1.2. All Magma functionality seems to work fine for low-volume activity. However, when the test-suite gets to the HA test cases (at the end), one of the images performing heavy networking activity, consistently gets very slow and bogged down for some reason; causing the clients to timeout and disrupting the test suite. Fortunately, it happens in the same place in the test-suite every time. The UI of the image in question becomes VERY sluggish, but MessageTally spyAllOn: didn't reveal anything useful. What is it doing? I did verify that the Magma server in that image is still functioning; clients were committing, but I had to increase their timeouts from 10 to 45 seconds to avoid timeouts.. Unfortunately, two days of wrangling in Pharo (because I'm an old Squeak dog) I could not nail the problem down; but I have one suspect.. A couple of times, I caught a process seemingly hung up in NetworkNameResolver; trying to resolve an IP from 'localhost'. This exact set of Magma packages is rock-solid on Pharo 1.1.1 and Squeak, but that doesn't mean the problem for sure lies in Pharo 1.2; maybe a networking bug in 1.1.1 is allowing Magma to "misuse" the network and get away with it and Pharo 1.2 is now more strict? I don't know, I would just like to ask the experts here for help who know all what went into Pharo 1.2 so hopefully we can get to the bottom of it. Thanks, Chris

Why merge? Lukas maintains OB and I am sure his version is fine for 1.2... So let's just load it. We just had to temporary fork to make it usable while 1.2 was not yet relased.
