I think the change of container from list to vector for ParagraphList is putting us in a bad situation. Remember the weird bug I had to solve with DEPM a few weeks ago: everytime you insert a paragraph in a document, all subsequent paragraphs are cloned and deleted because they have to move.
But the situation seems to be worse. Launch LyX and load Help>Introduction. See how the first paragraph has id 262. This probably means that the whole document has been allocated/deallocated/reallocated just be loading it. Strange. Now, in Document>Settings, change the textclass to article. This gives 3 errors, since the chapter headings have been changed to Standard. But the error list does not work: it searches for id 994 (which was 266 before switching class: document allocated three more time), but 994 does not exist anymore, it is 1258 already :) My problem is that I do not know where and why this happens... But this cannot be good for performance or memory fragmentation anyway. So, would it still be time to go back to std::list or something else? Can we have a vector of share_ptr<Paragraph> or some other wicked construct? Lars? JMarc
