Desktop deployment
by Noury Bouraqadi June 18, 2014

June 18, 2014

Hi, In the chapter on desktop deployment [1], what do the installers do? I'm more specifically interested in the Mac OS one. I guess it builds a .dmg file. What should I provide as input ?

UserManager hierarchy
by Pavel Krivanek June 18, 2014

June 18, 2014

Hi, most of issues with shrinking to the basic headless image are related to UserManager. Currently UserManager is subclass of DummyUserManager and I really think that we should change it to use the similar approach as the UIManager. UserManager (abstract class) - DummyUserManager (for no real users management) - KeyChainUserManager (or some other name, current UserManager class) The second option is to avoid the next strange "Dummy" class and make UserManager as concrete class with void functionality. It will be called using UserManager default or UserManager current instead of current Smalltalk tools userManager that makes unwelcome dependency of the kernel on tools. BTW I think that the message #current would be much better for UIManager too because it should be possible to use multiple UIs for the same image at once (e.g. Morphic and web-based UI) What do you think? Cheers, -- Pavel

Connecting ZnLogEvents to SystemLogger or Beacon
by Sven Van Caekenberghe June 18, 2014

June 18, 2014

Hi, I think we are all pretty much on the same page with how we think logging has to be done. In any case, here is the code (one, 1, line of code) that connects ZnLogEvent with either SystemLogger or Beacon - provided I understood everything correctly. ZnLogEvent announcer when: ZnLogEvent do: [ :each | BasicLog message: each ] for: #systemLogger. ZnLogEvent announcer when: ZnLogEvent do: [ :each | WrapperSignal log: each ] for: #beacon. Now this is using a wrapper object, BasicLog and WrapperSignal respectively. It even seems to work without the wrapping as well. ZnLogEvent announcer when: ZnLogEvent do: [ :each | LogDispatcher current addLog: each ] for: #systemLogger. ZnLogEvent announcer when: ZnLogEvent do: [ :each | Beacon announce: each ] for: #beacon. Question is, is the wrapping needed ? For the implementation or for the user ? Right now, only a timestamp is added. As I indicated before, I don't think that even 'forcing' a particular timestamp is a good idea. Here is my reasoning. Log events arrive in a certain order and that order should be maintained. Making log events sortable could be nice to have, but it is not 100% necessary. The same goes for uniquely identifying log events, nice to have but not necessary. A timestamp might seem like a good idea for both properties, but it is not. Consider: (Array streamContents: [ :set | 1000 timesRepeat: [ set nextPut: DateAndTime now ] ]) asSet. The set will contain only a couple of instances. And this is for the most precise timing that we currently have. It is also easy to think of alternatives for DateAndTime that some people might prefer: just Time, seconds, micro or milliseconds since a reference, ZTimestamp (which I use in other code), some class from Chronos, whatever. Features, abstraction, performance, precision, memory consumption are all different. But regardless of clock precision, I think an id is useful as a secondary sort or identity criterium, just in case. But again, I would not require it. On the other hand, we need common protocol. What about the following: each log event object should implement #timestamp, which has to return a Magnitude compatible object so that increasing values conform with the order of the events (but not necessarily vice versa).

[ann] beacon - a slim announcement-based logging engine
by Tudor Girba June 18, 2014

June 18, 2014

Hi, I like very much the new energy people are putting into creating the SystemLogger engine for Pharo. I think this is a specifically important area for which we have to have a solution out of the box. At the same time, I also think that Pharo provides an infrastructure that makes room for ideas that are otherwise hard to reach in other languages or environments. Stef asked for collaborations around this project, so here is my literally small contribution: a rather different logging engine. It is called Beacon, it is based entirely on Announcements, it has ~200 lines of code, it has no tags or levels, and in my opinion it is fully functional. You can see a detailed description here including some informal comparisons with SystemLogger: http://www.humane-assessment.com/blog/beacon Please let me know what you think. I would be happy to join forces to reach a mature solution that is both versatile and that can show how Pharo is different. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

zip filesystem test cases?
by Tudor Girba June 18, 2014

June 18, 2014

Hi, I am looking into how to fix the Zip FileSystem: https://pharo.fogbugz.com/f/cases/12826/Zip-FileSystem-does-not-work Has any of you ever used it before? Also, Camillo mentioned that he saw some test cases, but I could not find any (I also checked in the repo of Lukas). Does any of you have some more information? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
