Re: [Pharo-project] Fixed: Issue 2754 - DateAndTime creation from string/stream using incorrect default offset
thanks for the explanation. I will integrate your changes. Stef what is the DateAndTime localOffset? Answer the duration we are offset from UTC http://en.wikipedia.org/wiki/Coordinated_Universal_Time - In casual use, when fractions of a second are not important, Greenwich Mean Time (GMT) can be considered equivalent to UTC or UT1. In fact, saying GMT often implies either UTC or UT1. For this reason, saying GMT is generally avoided in technical contexts, with an unambiguous terminology of UTC or UT1 preferred instead. Stéphane Ducasse wrote: Your changes basically uses DateAndTime localOffset when no offset is specified (and before it used zero). It sounds reasonable but I was wondering the impact. Yes, that's correct. I changed it for two reasons: 1. when someone says, 6pm, I don't think they ever mean GMT (unless, of course, that's their local time). 2. The non-[string|stream] instance creation methods (e.g. DateAndTime date: Date today time: Time now) do not operate that way, and return a DateAndTime like 2010-08-10T17:11:36-04:00 (with my local offset) HTH, Sean -- View this message in context: http://forum.world.st/Fixed-Issue-2754-DateAndTime-creation-from-string-stream-using-incorrect-default-offset-tp2315601p2320464.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com. ___ Pharo-project mailing list Pharo-project@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project ___ Pharo-project mailing list Pharo-project@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

The functionality that is described here is better known as coalescing. And it describes better what is going. If a parser is coalescing two things will happen. CDATA sections will be read in as text nodes and then subsequent text nodes are coalesing into a single text node. my 2 cents, Norbert I think preserve is better, if only because coalesceCData just implies a joining together of CDATA sections and says nothing about their status in the DOM tree as XMLString or XMLCData nodes. Although I am not wed to it. I think it is hard to find a word that describes completely what ist going on. And I think that common sense/common usage is also kind of an argument. I didn't start to think of myself what would be the best describing word (quite hard as non-native speaker). If you search the net then you might see (as I did) that it is quite common that this effect is described as coalescing. That was my only reason to speak up because I think its recognition is better this way. If you know about coalescing than the state in DOM tree is pretty obvious. The nodes can coalesce only if they are of the same kind. While a cdata _is_ a text node all cdata nodes are converted to simple text nodes and then all of the text nodes coalesce into one. The state in the DOM is always that there is a single text node after coalescing.

And I'm always thorn apart when writing code if I should use s or not. I think we all want to figure out how it is done best in general. Discussing about a single selector in one piece of code would hardly justify a longer thread :) To me this is really important. I read the Becks but can't even remember which of those. Because it's none of these things you read and you can remember afterwards. Well, at least in my cast this doesn't work and far too lazy to read it over and over. It is 4 pages so this is worth the effort. I will reread them and smalltalk with style. and probably Smalltalk by example.

Re: [Pharo-project] Pharo benchmarks ?
2010/8/11 Cyrille Delaunay cy.delau...@gmail.com Hello, We are looking for any kind of benchmark in pharo, we would like to include such benchmarks in a reporting system for Pharo. Hi. This is an EXCELLENT idea and I really really hope you can make it. I would love to have an addon to Hudson that not only runs the tets, but also the benchmarks. With this, we can see the impact of every system update. At least, what we cover with the benchmarks. What I know is this: http://map.squeak.org/package/3273bc19-5799-4f0d-b303-acff5ffab9e6 http://www.squeaksource.com/SystemBenchmarks They probably won't work out of the box in Pharo but with some changes they may work. I don't know. But Marcus Denker or Adrian may help you much more than me.

Re: [Pharo-project] Instantiating an abstract class

Re: [Pharo-project] Inter-image communication
Which ultimately depends on sockets. Hopefully the next pass will support OpenSSL and be adaptable to things like IrDA (by having hooks sufficient to support anything that makes itself look like a socket), and make either robust use of asynchronous operations or OS threads to the point that non-responsive peers or DNS servers never lock the entire image, just the calling process. ConnectionQueue polls for connections - there needs to be either another semaphore, or another job for one that exists, allowing a process to wait until a client connects rather than looping and adding time delays :( Andreas' SSL plugin might be a good starting point or perhaps one part of a good solution?? Testing needs to be brutal, including viciously timed loss of power to network infrastructure. I am not sure if I can do that at work anymore, but I certainly can build an intranet. In fact, I have a really nice old machine that I rescued from the gas chamber, and an embedded computer (expected soon) that is part of a beta program and needs to be abused in various creative ways. Between them, I should be able to set up a very nice testing ground for network error handling.

Re: [Pharo-project] Closure bytecodes?
2010/8/11 James Ladd james_l...@hotmail.com Hi All, This list has been amazinly quick and helpful so thank you all. I'm continuing my adventure through the bytecode and I have a question about the bytecodes for closures. Below is an example dump of a closure ([]) 165 8F 10 00 1E closureNumCopied: 1 numArgs: 0 bytes 169 to 198 169 10 pushTemp: 0 170 C7 send: class 171 83 11 send: selectors 173 83 10 send: asSortedCollection 175 52 pushLit: WriteStream 176 53 pushLit: String 177 CC send: new 178 EA send: on: The number on the left I will refer to as the line number to make my questions more clear. Firstly, on line 165 the closure is reporting num copied 1. What is the 1 thing that it is copying? http://www.mirandabanda.org/cogblog/2008/06/07/closures-part-i/ http://www.mirandabanda.org/cogblog/2008/07/22/closures-part-ii-the-bytecodes/ Secondly, the send bytecode on line 171 is different to that on line 175. Is it because 175 is using a set of known selectors while 171 has to refer to a literal table? I think you mean lines 171 177 right? If so, then yes, #new is a special selector (see Smalltalk specialSelectors). best Eliot Rgs, James. ___ Pharo-project mailing list Pharo-project@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project ___ Pharo-project mailing list Pharo-project@lists.gforge.inria.fr http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

Re: [Pharo-project] Remove ParagraphEditor
sounds great! regards, Francisco 2010/8/11 Guillermo Polito guillermopol...@gmail.com: Hi! I've prepared a changeset where there are the following changes - replace ParagraphEditor by SmalltalkEditor - replace TextMorphEditor by SmalltalkEditor or TextEditor where it corresponds(or I suppose so) - some changes in SmalltalkEditor and some classes like Workspace, Inspector, ObjectExplorer... following the current versions of them in CUIS - lazy inicialization of keybindings in SmalltalkEditor and TextEditor - removal of ParagraphEditor and TextEditor I'm a little scared to submit this change to the inbox because I would like more people to try it... To install it you have to close every window, open the File browser, install the changeset and close the filebrowser, because if not there may remain references to AnObsoleteParagraphEditor.

Re: [Pharo-project] Closure bytecodes?
Hi Eliot, That is a very nice blog you linked me to. Lots for me to read there. I read this ... The final bytecode is more interesting. 143 1000 Push Closure Num Copied Num Args BlockSize This creates a closure, initializing it from the arguments and the current context. I'm missing something, is num copied the number of temps copied from the containing method?

Re: [Pharo-project] Closure bytecodes?
Hi James, 2010/8/11 James Ladd james_l...@hotmail.com Hi Eliot, That is a very nice blog you linked me to. Lots for me to read there. I read this ... The final bytecode is more interesting. 143 1000 Push Closure Num Copied Num Args BlockSize This creates a closure, initializing it from the arguments and the current context. I'm missing something, is num copied the number of temps copied from the containing method? It is the number of values copied from the stack that become locals of the closure. In Collectioninject: thisValue into: binaryBlock Accumulate a running value associated with evaluating the argument, binaryBlock, with the current value of the argument, thisValue, and the receiver as block arguments. For instance, to sum the numeric elements of a collection, aCollection inject: 0 into: [:subTotal :next | subTotal + next]. | nextValue | nextValue := thisValue. self do: [:each | nextValue := binaryBlock value: nextValue value: each]. ^nextValue the closure [:each | nextValue := binaryBlock value: nextValue value: each] accesses two non-local variables binaryBlock nextValue. Because binaryBlock is not modified its value can be copied directly but because nextValue is modified it cannot be copied and a shared location must be used to hold the value. So the compiler arranges to create an (in this case one-element) array (an indirection vector) to hold nextValue. The hidden variable holding the indirection vector is not modified so its value (the indirection vector) can be copied. Hence [:each | nextValue := binaryBlock value: nextValue value: each] has two copied values, one the value of binaryBlock and another a hidden Array that holds nextValue. Hence the bytecode: push: (Array new: 1) # create the indirection vector popIntoTemp: 2 # store it as the 3rd temp (after firstValue binaryBlock) pushTemp: 0 # push firstValue popIntoTemp: 0 inVectorAt: 2 # initialize nextValue with firstValue self# push the receiver of #do: pushTemp: 1 # push the first copied value binaryBlock pushTemp: 2 # push the second copied value, the indirection vector holding nextValue closureNumCopied: 2 numArgs: 1 bytes 31 to 40 # create the closure with 1 arg and 2 copied values pushTemp: 1 # push binaryBlock (the 1st copied value, the 2nd temp after each) pushTemp: 0 inVectorAt: 2 # push nextValue, the 1st slot in the indirection vector which is the 3rd temp pushTemp: 0 # push each send: #value:value: (2 args) # evaluate binaryBlock value: nextValue value: each storeIntoTemp: 0 inVectorAt: 2 # store the result into nextValue (1st slot in indirection vector) blockReturn # return nextValue as the result of the block send: #do: (1 arg) # evaluate self do: [:each|...] pop# discard the result of elf do: [:each|...] pushTemp: 0 inVectorAt: 2 # push nextValue returnTop # return nextValue as the result of inject:into: If this still doesn't make sense look at the version in the first blog post that uses an explicit array and compare it with the above.
