Behavior of absolute("") in v4

[Pesa]

(Like #300, I'm not sure if this is a bug or I'm misreading the documentation)

absolute() on an empty path is defined as being equal to absolute(base) / path(). Let's assume base is /foo. With Boost Filesystem v4 we get the following:

• absolute(path()) returns /foo
• absolute(base) / path() returns /foo/

This is because the behavior of operator/= changed in v4. Which one is correct?

[Lastique]

Which one is correct?

Both are, according to path modification rules in v3 and v4. This is intended behavior.

[Pesa]

Sorry, I'm not sure I understand. What do you mean that both are correct? Is the documentation of absolute wrong for v4 then?

[Lastique]

In what way is it wrong?

[Pesa]

It says:

Returns: A absolute path composed according to the following table [...] return absolute(base) / p

(I'm looking at the bottom right cell)

Not sure what "according to" means formally, but as I said earlier, for an empty path p, absolute(p) and absolute(base) / p give different results in v4.

[Lastique]

I'm not sure what the problem is. Yes, the result is different between v3 and v4, and that is as expected. The v4 result is correct - in v4.

[Pesa]

I'm not talking about v3, or the difference between v3 and v4. This entire issue is exclusively about v4.

[Lastique]

Ah, sorry, I misunderstood the original post. Yes, in v4, result should be /foo/.

Thanks!
