Yes, I copied the filename exactly. After clearing the cache and visiting a few images the cache is filled like this: $ find . -name '*blob' ./502/0x038c599924e70177.blob ./839/0x038c599924e70177.blob ./828/0x038c599924e70177.blob ./871/0x038cabfeee9f6c88.blob ./291/0x038c599924e70177.blob ./846/0x038c599924e70177.blob ./706/0x038c599924e70177.blob It could be that plone.app.blob does some monkey-patching. I am not aware of any other code in this project that could possibly be involved here. Ehm... there seems to be a a preoccupation with certain blob file names. In fact in a blob cache directory in this project there are only two distinct blob file names, even though there are a bit over one thousand files in exactly 1000 directories: $ find . -name '*blob' | cut -d "/" -f3 | sort | uniq -c | sort -g 61 0x038c599924e70177.blob 997 0x038c64edca37a033.blob $ find . -type d | wc -l 1000 That is pretty weird! I can understand a few duplicates because images are saved in a few sizes, but this is too much. To reiterate some versions: - Plone 3.3.5 - ZODB3 3.8.6-polling - RelStorage 1.5.0b1 - Zope2 2.10.12 - plone.app.blob 1.3 - plone.app.imaging 1.0.1 Blobs are stored in postgres with RelStorage. Layout of the blob cache dir is 'zeocache'. -- Maurits van Rees Web App Programmer at Zest Software: http://zestsoftware.nl Personal website: http://maurits.vanrees.org/ _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
