Image growing size

Hi all,

The official image i've downloaded weighted about 40 MB. Now its size is about 200 MB. What is the explanation? Is this normal or have i done something wrong?

I haven't been using globals, just downloaded and defined some packages. The only over persistent thing i've done is to keep an instance variable in some classes i wanted to have a unique instance.

Best,

Laura

Re: Image growing size

Try to open monticello and select any repo, right click and clear the package cache.

If you are using monticello that is.

Also close all windows, open a workspace and do the

10 timesRepeat: [ Smalltalk garbageCollect].

Re: Image growing size

Do any of your (class/pool variable) singleton instances store data? add a #clearAll or #reset (mySingletonVar := nil) to the class side -- or whatever fits your app -- and do that before that #garbageCollect block. [In fact, put that in some XXXAdmin class]

Good Luck,

Hello,

There could be many reasons why you would have such a big image.

The most common reason is the monticello metadata, as Phil said.

Another reason could be because some caches and objects that are flushed on snapshot, so if you looked at the image size at runtime and not the file size (for example, the Display object, which is huge, is not in the snapshot, same thing for the AST cache) it is bigger.

Another reason is that you may have kept persistent some data that refers to a huge graph of objects / a lot of objects. In the past, it happened to me that I kept errors in a collection to be able to debug them after the program execution (debugging directly the error would crash the image because it was errors in critical processes), but those errors were referencing a huge graph of nodes and after several thousands errors the image was overflowing its 1Gb limit.

So what do you keep persistent in your application ? Does it refer to a lot of objects without you knowing it ?

Re: Image growing size

I've tried, at some degree, all of your suggestions, but i failed to reduce the image size significantly. I'll keep trying, meantime i've started with a fresh image.

Thank you for your answers.

Re: Image growing size

Personally I never got a 200MB image size, you have very likely
persisted large collection of objects of your own in your image.

You might want to inspect this to see if this gets you something
interesting.

(Object allSubclasses collect: [ :aClass |
aClass -> aClass allInstances size])
sort: [ :a :b | a value > b value ]

It takes some time to run, especially in a larger image.

Re: Image growing size

Hi,

a fairly long report on the image and memory hogs is :

SmalltalkImage current reportCPUandRAM

Writes files in the image folder containing all the information. Takes a while to run.

I had this trouble with Squeak. It transpired that Squeak has a recycle bin! I changed a preference and all my junk objects disappeared.

The essence of object orientation is that objects collaborate to achieve a goal.

Cool. I didn't know that one. Thanks.

Re: Image growing size

Problemution (problem+solution) found!

I've tried

clearing package cache, image cleanup -> size decreased a little.

unloading all my packages -> size unchanged.

Yet i haven't thought as my doing about TilingWindowManager i've installed! It has an option for snapshooting worlds, it's possible i've been triggering it involuntarily with some shortcut i wasn't aware of, anyway if this was the case i get no visual notification when snapshooting (like the one you get when saving the image).

disabled TilingWindowManager -> size decreased about 200 MB, down to 20 MB.

Also the discussion brought up very interesting msg collaborations snippets and system features for future reference!

Best,

Laura

That sounds like an important discovery, there were memory complaints before, ...

I am using TWM and yes it gobbles memory.

Disable/GC/Enable is indeed aomething do every once in a while.

No need for snapshots for this to occur.

A couple of Nautilus windows do the same.

Youcan close them all in TWM and still have them eat memory.

Re: Image growing size

As I have discovered recently I quite regularly have large images (500+ MB); the reason seems to be combination of memory leaks, Roassal (maybe Athens), GUI, and a LOT of saving while having all those things opened. But Image cleanup tends to shrink it back to tens of megabytes.

Personally I don't care about the size but saving the image progressively slows done as it gets bigger.
