[1.33.0][Iostreams] Spelling mistake in documentation
by Paul 17 Aug '05

17 Aug '05

Hi, I assume someone has seen the couple of spelling mistakes in this paragraph, from the boost::iostreams tutorial page in the docs: <quote> Finally, I sould mention that the Iostremas library provides an easier way to read from an STL container: instances of boost::iterator_range can be added directly to filtering streams and stream buffers. So you could write: </quote> but i'd thought i'd mention it anyway. I searched the lists for 'sould' and didn't find any mention. see ya Paul

boost 1.33.0: Bug in property
by Philipp Thomas 17 Aug '05

17 Aug '05

boost_1_33_0/boost/pending/property.hpp has template <class Tag, class T, class Base = no_property> struct property : public Base { typedef Base next_type; typedef Tag tag_type; typedef T value_type; property() { } property(const T& v) : m_value(v) { } property(const T& v, const Base& b) : Base(b), m_value(v) { } // copy constructor and assignment operator will be generated by compiler T m_value; }; The bug here is that the empty ctor does not initialize m_value which leads to gcc 4.0.1 warning about m_value being used uninitialized. As our automatic build system rejects packages with such warnings I had to fix it :) This is the patch I'm using: --- boost/pending/property.hpp +++ boost/pending/property.hpp @@ -22,7 +22,7 @@ typedef Base next_type; typedef Tag tag_type; typedef T value_type; - property() { } + property() : m_value() { } property(const T& v) : m_value(v) { } property(const T& v, const Base& b) : Base(b), m_value(v) { } // copy constructor and assignment operator will be generated by compiler Philipp -- Philipp Thomas <pth(a)suse.de> Research & Development SUSE LINUX Products GmbH, Maxfeldstr. 5, D-90409 Nuremberg, Germany

Re: [boost] Propose adding Clone Smart Pointer (clone_ptr) to the boost library

But your example code has this problem. > I also think you're right in that I should add more to the > documentation Absolutely. I am sure that this code satisfied a real need that you had. What is not at all clear is whether that need is widespread enough to justify including the clone_ptr in boost. What is needed is some clear documentation including: - an explanation of what problems the class solves ("motivating examples"). Note this doesn't need to be very detailed as too why the problem exists at this point. I imagine most people on this list understand concepts like "slicing". - An overview of the class usage (including the restrictions on how the class may be used) - A description of the specification of the class and its members, including the concepts that the template parameters must model. (Don't worry too much about getting the English right. If the library does go into boost, plenty of people here can help with that later.) Finally you might like to consider the following: A) I can see how something like this might be useful to allow a copyable class which owns an object of a polymorphic type. However, under what circumstances is this better than providing a clone() member in the polymorphic type? B) Under what circumstances is a std::container<clone_ptr<T> > better than a boost::ptr_container<T>? -- Martin Bonner Martin.Bonner(a)Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 441434

Hello, I'm attaching the patch against unintentional(?) "Revision.." underlining (you can see it at boottom of htpp://boost.org page) BTW, Opera displays sans-serif as Verdana and it looks very well. Regards, Janusz

I couldn't see how clone_ptr was going to copy the dynamic type of the argument to the constructor without any information about that dynamic type. Having looked at the code, I don't think it does. It would work if the constructor was declared: foo(DerivedClass*p): m_MyAbstractClassPtr(p) {} or even template <class Derived> foo(Derived *p):m_MyAbstractClassPtr(p) {} but even that will fail if the constructor is called via: Derived *p = new DerivedDerived; foo foo_obj(p); My basic concern is that while clone_ptr could be useful, it only works if people stick rigidly to certain rules. Those rules need to be made VERY clear, otherwise it provides a plentiful supply of rope. It would also be useful to have some documentation of what methods clone_ptr provides, and what effects they have. -- Martin Bonner Martin.Bonner(a)Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 441434
