| Subdino | hi. I'm tracking down a high memory usage case in zope 2.8. from what I see, there are far too many ghost objects (20k+) although I set the maximum cache size (and I know it a soft limit) to 4000, suggesting that ghost objects do not obey the limit | 17:58 |
|---|---|---|
| Subdino | those ghost objects are documents in a big OOBTree, so they are referenced by a bucket, which is referenced by an OOBTree, itself referenced by another OOBTree | 17:59 |
| Subdino | so my question is: is there a way to "break" object references in btrees so that buckets can be freed from ghost cache ? | 17:59 |
| Subdino | I have no idea how to technicaly do it yet, like at which point the relation would be interesting to break, I just wonder if it is possible at all | 18:00 |
| mcdonc | Subdino: i don't *think* the cache size limits the number of ghosts. | 18:04 |
| mcdonc | i think the cache size instead limits the number of unghostified objects | 18:04 |
| *** goschtl has quit IRC | 18:04 | |
| mcdonc | and objects are reghostified when that limit is exceeded | 18:04 |
| Subdino | that's the behaviour I observe, yes | 18:04 |
| Subdino | mmh | 18:04 |
| Subdino | from the code, ghosts are flushed when the last reference to them (cache container not counting as a reference) is lost | 18:05 |
| *** mustap has left #zope3-dev | 18:05 | |
| Subdino | so my concern is how to cut down on references | 18:05 |
| Subdino | I'm not sure though about what happens when a transaction requires more objects than the limit allows. I think the required objects are kept live until the transaction ends, and not ghostified. but it's quite hard to observe (I tried to set cache size to 0, but then I hit a considerable amount of errors related to volatile attributes) | 18:09 |
| mcdonc | i think they are only controlled at txn boundaries | 18:11 |
| mcdonc | i'm not sure what would refer to a ghost other than the cache container given everything else is equal | 18:13 |
| mcdonc | Dozer might help here if this is a web app: http://pypi.python.org/pypi?%3Aaction=search&term=dozer&submit=search | 18:13 |
| *** sunew_ has joined #zope3-dev | 18:16 | |
| *** sunew_ has quit IRC | 18:18 | |
| Subdino | I (naively) tracked references, but from python code, so I'm not sure if it's done well: I picked up an OID from detailed cache view of a document which is in my big btree, then grabbed the document via jar, and followed recursively gc.get_referrers() | 18:23 |
| Subdino | that's how I found that the document is referenced by a bucket, referenced by an oobtree, etc | 18:23 |
| Subdino | iirc the bucket is still a live object, not a ghost (and the document is a ghost) | 18:23 |

| supton | generally speaking, how expensive is notify() for an event, if called frequently? I'm considering notifying IObjectModifiedEvent in an application on each property set for a content object with dozens of fields; my handler only updates a datetime field on the object | 23:18 |
| *** whit has quit IRC | 23:23 | |
| mcdonc | supton: notify itself is really cheap but its listeners might be arbitrarily expensive (but you probably knew that) | 23:32 |
