by seaside＠rmod.lille.inria.fr

Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts. Just answer informally, and feel free to spawn discussions thereafter! ### Here's what I've been up to since the last WhatsUp: - $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS ### What's next, until 2014-10-31 (*): - $NEXT_STEPS_TOWARDS_WORLD_DOMINATION (*) we'll be expecting results by then ;)

Image Segment semantics and weakness

by Eliot Miranda

Hi All, I want to check my understanding of reference semantics for image segments as I'm close to completing the Spur implementation. Specifically the question is whether objects reachable only through weak pointers should be included in an image segment or not. Remember that an image segment is created from the transitive closure of an Array of root objects, the *segment roots*. i.e. we can think of an image segment as a set of objects created by tracing the object graph from the segment roots. The segment always includes the segment roots. Except for the roots, objects are excluded from the segment that are also reachable form the roots of the system (the *system roots*, effectively the root environment, Smalltalk, and the stack of the current process). Consider a weak array in the transitive closure that is not reachable from the system roots, and hence should be included in the segment. Objects referenced from that weak array may be in one of three categories - reachable from the system roots (and hence not to be included in the segment) - *not* reachable form the system roots, but reachable from the segment roots via strong pointers (and hence to be included in the segment) - *not* reachable form the system roots, *not* reachable from the segment roots via strong pointers Should this last category be included or excluded from the segment? I think that it makes no difference, and excluding them is only an optimization. The argument is as follows. Imagine that immediately after loading the image segment there is a garbage collection. That garbage collection will collect all the objects in the last category as they are only reachable from the weak arrays in the segment. Hence we are free to follow weak references as if they are strong when we create the image segment, leaving it to subsequent events to reclaim those objects. An analogous argument accounts for objects reachable from ephemerons. Is my reasoning sound? -- best, Eliot

Use Komitter in MC Browser?

by Sean P. DeNigris

I hacked the MC Browser to open up a Changes window along-side my commit dialog. Then I realized we already have this (and a bit more) with Komitter. What if we just plug Komitter into the "Save" operation? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Use-Komitter-in-MC-Browser-tp4785411.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Issue 14269 Komitter: Improve layout for long repo names

https://pharo.fogbugz.com/default.asp?14269 Right now, no matter how wide the Komitter window is, the repo drop down often too narrow to see the repo names: <http://forum.world.st/file/n4785409/Screenshot_2014-10-19_16.png> Fix in inbox: SLICE-Issue-14269-Komitter-Improve-layout-for-long-repo-names-SeanDeNigris.1 - Add vertical splitter and intially equal columns between commit message widget and author/repo widgets Ready for review. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Issue-14269-Komitter-Improve-layout-for-long-repo-nam… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] Spec Understandability

by Sean P. DeNigris

Sean P. DeNigris wrote > What is one supposed to do with an error like this? > [snip] Besides error intractability, there is also a cost to understanding the system via exploration - a glorious benefit of Morphic. In the past, one only had to bring up halos on and inspect a button to see how to duplicate its action. Now, to see what happens when one presses Versionner's "Commit the project" button, you have to drill down in the inspector from aButtonXyzMorph -> model -> actionHolder -> value, a tedious and opaque process. Of course, I'm not in any way against Spec or its goals, just sharing my unfolding experience using it. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Spec-Understandability-tp4778370p4785401.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Re: [Pharo-dev] pharo works fine on yosemite

by kilon alios

thats great news, i am in the process of downloading Yosemite and I have my fingers crossed for many apps as this is the first time I install a new macos version so quickly after its release. Most likely I will be fine though. On Sun, Oct 19, 2014 at 2:16 PM, Max Leske <maxleske(a)gmail.com> wrote: > Iâve been developing with Yosemite for the last two weeks.

Iâve been developing with Yosemite for the last two weeks. There seems to be one issue with older VMs that can lock up from time to time. Other than that I havenât experienced any difference to Mavericks (except for the nicer full screen view :) ) Cheers, Max > On 19.10.2014, at 12:57, phil(a)highoctane.be wrote: > > Cool.
