Re: [Pharo-project] [SPAM] Re: why are Bitmaps instanciated even in headless mode?

by Schwab,Wilhelm K

Options are always good. I would not at all recommend removing the current null display and sound drivers. However, it would be nice to see the image and vm cooperate to emulate Dolphin's session managers and associated deployment design. IMHO Object Arts went a little overboard with stripping; we would not have to work that hard at it to have something very useful.

Default actions that return nil merely push problems down stream to a point where there is no context to figure out what went wrong. I think much of this goes back to the late 70's and early 80's, before structured exception handling, and has never been modernized. Dolphin, which started life in the mid 90's, is built from the ground up to do these things correctly. Once one learns that the exceptions are indeed helping to make things work reliably, it is hard to imagine making something robust without them. > > Exceptions can be expensive, both to set up handlers, and even more so when exceptions are thrown. You have identified the answer, which is to provide #readFrom:ifFail: (or #readFrom:onError: - whatever you want to call it) that evaluates a block when things go wrong, which allows one to bypass the overhead, much like #at:ifAbsent:; if error and remedy are near by, it is easy to do and skips the overhead. For the lazy<g>, or simply for frameworks that can/should use exceptions to handle exceptional conditions (big separation between the problem and anything that knows how to cope with it), #readFrom: (without the block) does the robust/correct thing, and raises an exception. As you no doubt know, it can (often should) be written in terms of #readFrom:ifFail: with the block raising the exception. > > Things will break for a while, but I hesitate to think how much stuff is just plain broken and we never notice it because things answer nil and/or ignore error conditions. The industry tried to formalize such head-in-the-sand-hope-it-goes-away design under the fancy name "defensive programming." It remains a useful approach when used sparingly to keep critical systems running, but it generally failed under its own lack of merit. It was popularized as a way to cope with the dreaded UAEs of 16 bit Windows, which was in turn due to the lack of exception handling and ensured execution in the GUI, which lead to incomplete cleanup, memory leaks, and all kinds of crashes. > > YES.

Since it quickly became obvious to me that #next and #next: were not going to change any time soon, I simply stopped using them myself; instead I write code using #nextOne, #nextMany:, and #nextAvailable:.

I also have some text converters modeled after Dolphin's framework. I don't think I have released those yet, but plan to do so eventually.
