Re: [Pharo-project] Pharo Smalltalk + Riak = Phriak

by Nicolas Petton

BTW, I'll release RiakDocument soon, a Magritte-described layer on top of Phriak that we use for saving data in SmalltalkHub. Ohh, and I'll have good news about SmalltalkHub soon ;) Cheers, Nico On 15/02/12 11:50, Nicolas Petton wrote: > Hi! > > GÃ¶ran and I worked on a Riak client for Pharo Smalltalk named Phriak. > You can download the code at http://www.squeaksource.com/Phriak > Today I released the version 0.3. > > Riak is a screamingly cool NoSQL database that scales like crazy.

[Pharo-project] Pharo Smalltalk + Riak = Phriak

by Nicolas Petton

Hi! GÃ¶ran and I worked on a Riak client for Pharo Smalltalk named Phriak. You can download the code at http://www.squeaksource.com/Phriak Today I released the version 0.3. Riak is a screamingly cool NoSQL database that scales like crazy. It's a distributed, data agnostic db (see http://wiki.basho.com/Riak.html) There's a Metacello package ConfigurationOfPhriak for simple loading. As of today, Phriak supports (through the HTTP API): - Bucket properties - Objects metadata - Links and link walking - Secondary indexing - Map/Reduce - VClock and Siblings resolution Cheers, Nico -- Nicolas Petton http://nicolas-petton.fr

Indeed. Now I would love that we rethink our trait implementation and tool support but no time. On Feb 15, 2012, at 6:40 AM, blake wrote: > This is kinda cool: > > http://phpmaster.com/using-traits-in-php-5-4/ >

Re: [Pharo-project] garbage collection

by Henrik Johansen

I sort of doubt Magma uses anything registering external objects but the standard Socketsâ¦ While interrupting finalization process _could_ be a culprit, I'd rather watch for something like what happened with the InputEventFetcher, where registration/deregistration ends up not being symmetric. Perhaps Magma tries to reuse existing Socket instances by calls to initialize:/acceptFrom: for example? I think changing ExternalSemaphoreTable to a weak structure would be a really bad idea btw. All of a sudden, you free up slots which were previously taken for insertion of old objects. There is no guarantee the external user of the semaphore will stop using the index it was given just because the image no longer holds a reference to the object which used to occupy that index. So if you register a new object in the same slot, in the case of Sockets at least, you could potentially end up responding to signals from both the old external user, and the new one. TLDR; Any object registered in this table by definition needs explicit cleanup of external users before they are GC'd. Thus, making the table weak makes no sense.

Re: [Pharo-project] troubles with glamour finder in pharo 1.4

by Tudor Girba

Thanks, Ben. You can: - load it in Pharo 1.4: Gofer new squeaksource: 'Glamour'; package: 'ConfigurationOfGlamour'; load. (ConfigurationOfGlamour project version: 'default') load: #('Core' 'Morphic') - or download the ready-made Moose image: http://ci.moosetechnology.org/job/moose-latest-dev/lastSuccessfulBuild/arti… To reproduce the problem, try this: GLMFinder new show: [:a | a list display: [:x | 1 to: x ]]; openOn: 100 and then click on the first and on the second to try to get the third pane. The third pane does not appear, but the scrollbar does. The relevant code is in GLMPaneScroller.
