Hi Marcel,


just two notes from my side, but no clear opinion here. :-)


> I assume that the user can spare those extra megs on disk while working.


On my main machine, I have 233 .image files with 28 GB in total. So maybe "those extra megs" could indeed be relevant ... But I did not do a rough calculation. :-)


> Which server images save on a regular basis? :-D


The image for https://t.me/SqueakSmalltalkBot does, once in ten minutes. Will this increase the wear and tear of my raspi's SD card? :-) To be honest, I would prefer it if "Smalltalk snapshot: ... andQuit: ..." would support the server use case out-of-the-box, too, without extra scripting. But if we are only talking about a few kilobytes here, I don't mind. :-)


Best,

Christoph

Hi Tim --

I know. Is this a problem? I assume that the user can spare those extra megs on disk while working. Yet, it is annoying to get a stuttering system after snapshotting, which might even encourage people to not save that often.

Which server images save on a regular basis? :-D You can always call "Form shutdown: true" and "TTCFont shutdown: true" in your server scripts directly before snapshotting ... I assume that servers have such scripts anyway and those two extra lines wouldn't hurt...

Best,
Marcel

The problem here is image file bloating; the hibernation is intended to save (quite a bit of) space in the image file. If we only hibernate when save&quitting then we will see patterns in the snapshot file size like

100mb
112mb
121mb
(quit) 101mb

.. which maybe wouldn't bother anyone, maybe would annoy some?

Also, a few save-no-quits followed by a damn-I-broke-it-quit-no-save would lave the large file as the one you have to start up. It should start ok but might be a problem for server cases where startup time is important?

High-tech-insane solution - use DTL's spawn-an-image and have that image do the hibernate & save! Couldn't possibly go wrong...
