[Pharo-project] Startup/shutdown anecdote
by Schwab,Wilhelm K Sept. 15, 2009

Sept. 15, 2009

I just had an experience that fuels my session manager fire. I loaded Pharo, and it was totally unresponsive. Why? I can't be absolutely certain, but here's my story: last night, I had an open connection to a system visible only with a vpn. With the vpn not in use, either Pharo (or more likely ODBC) went nuts because it could not find the server, and I finally killed the process, started the vpn, and all was well on the next startup. IMHO, hanging like that is one of the worst things software can do, and I think we can do a lot to fix it with a few simple changes. Linux ODBC is probably partly to blame, but it should not have been invoked so early in statup. Someone recently argued against lazy connections, but this would not have happened if they were part of the design. The image would have become helpless once I did something that triggered database activity, but that is where overlapped calls enter the picture. Even without the, at least I would have been able to use the image. Note that if I had taken the offending image to another machine, it could have been useless - not good. Bill

[Pharo-project] [update] #10453
by StÃ©phane Ducasse Sept. 15, 2009

Sept. 15, 2009

10453 ----- - adding removeAll to collections (missing some of them of course) from nicolas add #removeAll suport to collections This is to solve both http://bugs.squeak.org/view.php?id=7177 http://bugs.squeak.org/view.php?id=6937 Comments about the implementation: The super implementation might be enhanced with a shallowCopy in order to provide a working implementation in more cases: self shallowCopy do: [:each | self remove: each]. I believe much subclasses will override, so I did not even bother. Subclass implementation tries to preserve original capacity. This choice is arbitrary and really depends on application side... CharacterSetComplement use a #become:. This is not efficient, but neither would be the addition of all existing characters to the complement (this set is defined by its complement as the name tells). Collection>>#removeAll: also has been modified to handle case of (self removeAll: self). This extends and supersedes the changes from kwl at http://bugs.squeak.org/view.php?id=6937 The big question is what should (self removeAll: self) return? My answer is simple: it returns self (an empty collection). Beware, this will break some chaining: (b removeAll: (a removeAll: a)) ~= (a removeAll: (b removeAll: a)). Anyway, that is not worse than current implementation which will not lead to the most predictible results.

[Pharo-project] Unable to type some czech characters
by Bc. Martin ZÃºber Sept. 15, 2009

Sept. 15, 2009

Hello, I have tried to write some czech text in Pharo, but have found some problems with characters. Have anyone found similiar problem? Here is description of the situation: SMALL CAPS C CARON U+010D: - when written directy (key "4") pharo writes EOL - when typed using dead key CARON and then "c", the char si shown normally in editor SMALL CAPS E CARON U+011B: - unable to write the char directly (key "2" or CARON+e) - pressing two times the key "2" opens the menu "do it, print it..." All these chars can be typed in upper case using the dead key CARON and the char in upper case including upper E CARON. My environment: Windows Vista SP 1 Home Premium CZ, keyboard Czech QWERTY, Pharo1.0beta Latest update: #10446. The useLocale setting is ON for enabled, OFF for local. I have tested another characters, which are in czech alphabet and haven't found any problem. Any idea? With regards Martin

Oops sorry for the dumb post.. (im using my friend laptop and not very handy with keyboard) There is a generic morph, which made specially for scrolling views which not fit fully within display.

thanks, Stef, i will check those packages and the original paint in squeak and start building on the PolyMorph application example + Morphic-Windows / ScrollPane example. i will share iterations as i complete them. delbert -----Original Message----- From: St?phane Ducasse [mailto:stephane.ducasse@inria.fr] Sent: Saturday, September 12, 2009 03:01 AM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Graphics-Centric UI Capability?

Because you have some graphs but they do not use Polymorph. Now once you find please advertise it.

thanks for the reminder, Bill, i will keep device-independence in mind, without losing the understandability of a basic example. delbert -----Original Message----- From: Schwab,Wilhelm K [mailto:bschwab@anest.ufl.edu] Sent: Friday, September 11, 2009 07:10 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Graphics-Centric UI Capability? Caution: this is *not* the answer to your question; I will be waiting to see what the experts say on the subject. One thing I _can_ tell you is that it is often a good idea to write graphics-producing code in terms of a canvas such that it can draw on "anything" (display, image file and printer come to mind) using the device resolution to scale things correctly. I have long been amazed that people create (in Dolphin speak) their own views when an image presenter would the job given a "background" bitmap. There are always exceptions, but IMHO you should at least consider drawing on a Form and displaying that in a appropriate morph, or whatever the gurus suggest. I hope that makes at least some sense.
