Moved from SingletonsAreEvil in Jan. 2005. The discussion below appears to have taken place in 2002.
I hope you don't delete this page. This page is distinct from SingletonPattern because it expresses a peculiar, controversial judgement about singletons. I'm already disappointed that this page has been watered down from its rhetorically excessive former glory. Also, the SingletonPattern page has grown enormous. -- BenKovitz
Mar 18 2002: Regroupings, nothing added or deleted. -- francis
Apr 8 2002: Regroupings. (Hm, this refactoring would go more quickly if the stuff on this page didn't make me feel so dumb ...) -- francis
Apr 20 2002: Moved lots of text to SingletonPattern. -- francis
Francis, I just retrieved a relevant chunk of the 'double checked locking' page and stuffed it into the singleton page. It looks like most of the issues are in there now. I'm not sure whether it's best to condense the issues on the one page, or refactor them into lots of little pages which express each issue. I like the idea of the latter, but don't want to get in your way. Nice to see someone getting on with it. Cheers. :) -- RichardHenderson.
Thanks for the help.
The reason I'm doing this is because I don't think SingletonsAreEvil is a sufficiently distinct page title from SingletonPattern. I'd rather SplitByTopicNotByOpinion, so eventually we might have pages like SingletonCreation? and SingletonsAreGlobal?, or whatever. Moving everything to SingletonPattern is just an intermediate step. -- francis
Feb 20 2003: Moved text to SingletonPattern. -- francis
Wow, this is a very very bad refactoring. This used to be a page I could direct people to. Now, well, I guess I'll have to wait until you get rid of this page and then I'll make another one with the same title. So, Francis, you "don't think" it is a good idea to have this page. Perhaps, we should do some kind of poll. I'll bet I can drum up several hundred people that "do think" it is a good idea to have this page. One of the great values of the Wiki has been to have a place to discuss opinions. You are in the process of destroying that value. Perhaps, I'll move on as many others have. -- MikeCorum
Francis, I'm a great admirer of your work, but I think you've erred a little here; whilst the idea of "merging this page into SingletonPattern [because] it contains a lot of interesting text that would be easier to find" is a good one (information wants to be useful!), to "refactor it away into nothingness" would, I think, be an error. The name reflects an opinion which some people evidently hold, and which has attracted useful discussion; it's also a classic hackish way of naming the position. Perhaps the final form of the page should reflect its name: it should state the case and refer to problems with singletons (on their own pages) - with, if possible, a healthy dose of excessive rhetoric! -- TomAnderson
Plus then MikeCorum and (presumably) others would be able to direct people to a page for the specific problem they're referring to in each particular case (if they have a particular one in mind).
I'm sorry if other people think this is a bad refactoring. I thought I was doing the right thing, but then, I never claimed to be perfect. Allow me to state my concerns, and why I did what I did, and maybe we can come to a solution that keeps everybody happy.
If I remember the state of the singleton-related pages correctly in the past, there were actually three separate pages covering the topic in general: SingletonPattern, SingletonsAreGood, and SingletonsAreEvil. After a time of heavy discussion all three were quite big and sprawling, which leads to problems like:
I'd also like to make it clear that my attempts at refactoring are in no way an attempt to rewrite the discussion to give the "Singletons are good" side the upper hand. I don't consider it a resolved issue. SingletonPattern is, to me, the best neutral title for this material to start at. Just because I'm advocating that we do away with the page title SingletonsAreEvil does not at all mean that I'm advocating we do away with that opinion.
But others are saying they found the page useful for expressing a certain sort of opinion. I think that's legitimate. Maybe they're seeing a form there that I couldn't see. From my memory, it looked a lot like the original SingletonPattern page. That page goes like this:
It would appear that the smart thing to do is to put the pros and cons in bullet points in SingletonPattern, then reference all discussion to a SingletonPatternDiscussion? page. This seems to be the trend in reducing clutter and duplication for other contentious issues. I'm trying to do some of this for the document and requirements pages; work is going slooooow. -- MartySchrader
So then would we delete this page? -- francis
Affimative. I imagine all the Singleton diatribe can be pared down to a single page, either as a pro/con DocumentMode thing or as a point/counterpoint "discussion" between two DramaticIdentity actors, a la DialecticMode. Eh?
I suggest restructuring thusly:
