Recently logged changes - some hidden / missing functionality
by itsme213 08 Jan '08

08 Jan '08

I am getting more familiar with the dreaded "Recently logged changes" than I like. Is any of the following available? - directly cut off all items before a certain time (I cannot seem to sort the whole list chronologically) - pick one of most recent items tool shows preceding items you either must or might need - if class is missing, more recent corresponding DoIt: - for method chosen, most recent methods in its called set (perhaps transitively) - search for class | method | string These are more about finding the ones I need, less about eliminating the ones I don't need. Thoughts? Sophie

Swazoo 2.1 web server released
by Janko Mivšek 08 Jan '08

08 Jan '08

Dear Squeakers, New Swazoo 2.1 is released, with an easier startup as a main new feature. Now you can start simply by: SwazooServer startOn: somePort and Swazoo will start listening on all IP interfaces on your machine. It will also ignore host in web requests. This is very handy for running Swazoo behind load balancers and is the same as WAKom startOn: somePort on Commanche. This version is also much improved in terms of serving directly to the wild wild Internet. It is available here: o Damien's squeak-web image: http://squeak.ofset.org/squeak-web/ o Universes: Network, Swazoo version 2.1 o SqueakSource: http://www.squeaksource.com/Swazoo.html, Releases, Swazoo.2.1.mcz See http://www.swazoo.org for more Swazoo can be now used as a web server for two web frameworks: * Aida/Web: On Squeak and VisualWorks: load version 5.4 or later * Seaside 2.8, 2.9: On Squeak load from Universes (Web development beta): Seaside-Adapters-Swazoo For instance, on Damien's squeak-web you can now run both web frameworks side by side: SwazooServer demoStart then open http://localhost:8888 SwazooSeaside startOn: 8088 then open http://localhost:8088/seaside Best regards Janko Mivšek Maintainer of Swazoo

Backporting operation in Monticello
by Bergel, Alexandre 08 Jan '08

08 Jan '08

Dear List, What is the exact meaning of the Backport button in Monticello? The method MCWorkshopCopy>>backportChangesTo: suggest that a package is "adapted" to one of its ancestor. Is there a difference with loading a new version of its package?

Process>>terminate woes
by Andreas Raab 08 Jan '08

08 Jan '08

Hi - I had an eventful (which is euphemistic for @!^# up) morning caused by Process>>terminate. In our last round of delay and semaphore discussions I had noticed that there is a possibility of having a race condition in Process>>terminate but dismissed it as being of an application problem (e.g., if you send #terminate make sure you have only one place where you send it). This morning proved conclusively that this is a race condition which can affect *every* user of the system. It is caused by Process>>terminate which says: myList remove: self ifAbsent: []. The reason this is so problematic is that the modification of myList is not atomic and that because of the non-atomic modification there is a possibility of the VM manipulating the very same list concurrently due to an external event (like a network interrupt). When this happens in "just the right way" the effect is that any number of processes at the same priority will "fall off" of the scheduled list. In the image that I was looking at earlier we had the following situation: * ~40 processes were not running * The processes had their myList be an empty linked list * The processes were internally linked (via nextLink) * The processes were all at the same priority Given that most of the processes were unrelated other than having the same priority I think the evidence is pretty clear. The question is now: How can we fix it? My proposal would be to simply change primitiveSuspend such that for a non-active process it will primitively take the process off its suspendingList. This makes suspend a little more general and (by returning the previous suspendingList) it will also guard us against any following cleanup (like the Semaphore situations earlier). Unfortunately, this *will* require VM changes but I don't think it can be helped at this point since the VM will be manipulating these lists atomically anyway. The good news though is that we can have reasonable fallback code which does just exactly what we do today as a fallback to primitiveSuspend. Any comments? Alternatives? Suggestions? Cheers, - Andreas

Arrays / collections with literal syntax - fixed size?
by itsme213 07 Jan '08

07 Jan '08

Are #(...) and {...} the only 2 short, non-message-passing syntaxes for creating collections? They both seem to yield Array, which apparently has a fixed size. I'm curious about why the only (I think) convenient syntax for simple collection usage has this restriction on what you can do with it. And as far as I can tell, there is no similar convenient syntax for dictionaries. Is that true? I am trying to build up some simple declarative meta-data structures and find a big jump in verbosity from simple syntax to constructing things by message-passing. Thanks - Sophie

Version name in Monticello
by Bergel, Alexandre 07 Jan '08

07 Jan '08

Hi List again, Recently I discovered that the name of a version may be changed when saving. What is the typical situation to do this? It seems that changing name may put MC into trouble. It may be hard to see different branches. Any comment on this?

by merlyn＠stonehenge.com 07 Jan '08

The initials "pf" aren't registered. :( I need to know if more maintenance is planned, or if I can just take over... I found a problem with the types returned in the current protocol. -- Randal L.
