Difference between version and

At line 69 added one line
I'm more concerned that there is introduced an opportunity for errors and lost data. What should the wiki do when there is an unknown placeholder? What if the placeholder is duplicated? Data loss is possible when the user tries to move text between pages, or even on the same page, but in two edits -- he will cut the text, save to see how it looks, edit again and paste the text in different place. There is also a possibility of accidental modification of the hash during editing, either by the user himself, or by the text editor (line breaking, autoindenting, spellchecking, autocompletion). The main problem is that such a failure is fatal -- once you save, even pasting the text back wont help, because the placeholder is already deleted on the server. Sure, it's a wiki, so you can probably revert to a previous version and then retry all your changes -- but this in truns destroys the user's work. Turning the "hash" into an actual "perfect" representation of the data, just compressed and base64-encoded is one solution.

To sum up -- I agree that it can be advantagues to use hashes in cases of elaborate elements -- especially when they can contain whitespace and normal text. But at the same time, this has several drawbacks making the whole editor a **little** less friendly and faultproof -- so it seems that the technique can be avoided when it's not actually necessary: when the text of contained object is actually short and robust (no whitespace or other things that could make it look similar to other page content).
