ok Steve,

U tell us " ...Silently overwriting files is not a sound practice, 
because the files are almost always not the same, so overwriting them 
would make for even worse bugs."

I agree is not a good practice to silently kill non convenient output 
-but- and is a BIG but which in many cases is not considered .. is to 
obvious, let's talk a bit about this bug on the last 2 months ... in 99% 
of last cases ( as on my experience ) was the same file name and version.

If you read carefully what I wrote there about file control ( there are 
few methods - including parsing file content [as brute force] ) you can 
realize that must be not so hard to find a method to see if is the same 
file with the same content - OR not.

Now - if is the same file - the same content - I don't see the reason to 
not overwrite. ????

So I not recommend that as a best practice - but if we have an evidence 
- why we  should stuck on the problem instead of going forward.

Now the second point. If is not the same file -> User can choose what to 
do. OR if we don't consider here so smart users - then a rule (or more) 
must be defined ( regarding the same filename => to keep the bigger 
version / to keep the larger file / or some... ).

Enfin - this can be good for both parts - for the distro and for  the 
independent programmer. If you made a program distributed by others you 
will enjoy idea to put a RULE file on your package - that can be 
interpreted by the mister "Update Manager" - to see what he can do in 
any case. It's about a simple file where -> case 1 -> do that, case 2 -> 
overwrite, case 3 -> delete older file put the newest, case 4 -> phone 
home ...etc.

That's the point - not to ignore this bug ( is too often repeated, 
search bug reports from the last 2 years ...). So please consider a 
possible solution eventually ONLY for the case where we have SAME 
VERSION - SAME NAME - SAME CONTENT ( generally python scripts from 
different sources put the same files in site).

An we just walk forward a bit.

..On my opinion of course.

Anyway, that's my message -> from time to time is good to go somewhere 
on a higher point to see what's here down -> just to not forget the big 
picture.
