OK, this was was my experiment.... Image fresh with all my app and dependencies loades: 30MB
After using it for some days/weeks: 160MB. SpaceTally new printSpaceAnalysis showed: Class code space # instances inst space percent inst average size ByteString 2785 413144 116244078 69.90 281.36 Array 3712 181772 8466668 5.10 46.58 ByteArray 8574 1319 8186802 4.90 6206.82 Bitmap 3653 303 6656340 4.00 21968.12 CompiledMethod 22467 90554 5685374 3.40 62.78 After executing ImageCleaner cleanUpForRelease: 36MB Then...I searched which part of #cleanUpForRelease: was making the difference, and it was: Smalltalk cleanUp: true except: #() confirming: false. So now it was time to know WHICH class did the diference, so I modified #cleanUp: aggressive except: exclusions confirming: aBool in these lines: "Run the cleanup code" classes do:[:aClass| Transcript show: 'Image size before cleaning ', aClass name, ' : ', Smalltalk imagePath asFileReference size asString. aClass cleanUp: aggressive. 3 timesRepeat: [Smalltalk garbageCollect]. Smalltalk snapshot: true andQuit: false. Transcript show: 'Image size after cleaning ', aClass name, ' : ', Smalltalk imagePath asFileReference size asString. ] displayingProgress: [:aClass| 'Cleaning up in ', aClass name]. I then opened a Transcript, and evaluated Smalltalk cleanUp: true except: #() confirming: false. I went to prepare Mate, and when I come back, the result was, of course: "Image size after cleaning MCFileBasedRepository : 39744008" That clean up ends up doing: flushAllCaches self allSubInstancesDo: [:ea | ea flushCache] So it sends #flushCache to all instances of MCHttpRepository and MCFileBasedRepository. Now what I wanted to see if it there was a particular repo that could take most of the space (like package-cache). And indeed, it was...I modified #flushCaches to: flushAllCaches | file | file := 'repos.txt' asFileReference writeStream text. self allSubInstancesDo: [:each | file nextPutAll: 'Image size before cleaning ', each printString, ' : ', Smalltalk imagePath asFileReference size asString; cr. each flushCache. 3 timesRepeat: [Smalltalk garbageCollect]. Smalltalk snapshot: true andQuit: false. file nextPutAll: 'Image size after cleaning ', each printString, ' : ', Smalltalk imagePath asFileReference size asString;cr. ]. file flush; close. And then I looked in the 'repos.txt' file. My package cache repo cleaned 60 MB. Glorp cleaned 35MB. Seaside30 cleaned 10MB. So...cleaning cache of just 3 repos frees approx 100MB. The question is....can we flush the cache safely? If they are called "cache", then I guess yes, we can. Thoughts?
