72039 - validate |std::auto_ptr| for use in mozilla

Status: RESOLVED WORKSFORME

(Core :: XPCOM, defect)

Description

[Patrick C. Beard]

I propose that we implement an XP version of STL's auto_ptr<T> class, say 
nsAutoPtr<T>, which has essentially the same semantics. This will clean up lots 
of code in the tree, which deals with early returns using goto's, currently a 
necessary evil.

c'mon scc, i double dog dare ya! now you have to do it! ;)

Comment 2

[Scott Collins]

I don't understand what's wrong with the |auto_ptr| that's in the standard
library (provided as part of <memory> or <memory.h>, not in some arbitrary `STL'
header).  Is |auto_ptr| known not to work?  It would suck to steer people away
from one of the best utilities in standard C++.

The bug summary still seems appropriate if I change the task of the bug to
validate |std::auto_ptr| for use in mozilla.

[Darin Fisher]

aren't there issues with member templates?

Comment 4

[Scott Collins]

Presumably, those compilers that have problems with member templates won't have
the member template part of |std::auto_ptr| enabled. We can live without the
automatic conversions these provide in this case, I think.

We have a nsAutoPtr now
