[filesystem] status() if neither file nor directory?
by Beman Dawes 12 May '05

12 May '05

In http://www.esva.net/~beman/filesystem_operations_predicates.htm, the assumptions was that file system entities are either files or directories. But an operating system might support additional file system entities which can only be accessed via a specific API, and can't be accessed via fstreams or directory_iterators. For example, on some operating systems, sockets are file system entities and may be found during directory iterations, but can't be opened as either directories or fstreams. What to do? Possibilities: 1) Add an other_flag and a matching is_other() function. Change definition of exists() to status() & (directory_flag|file_flag|other_flag) 2) Try to identify specific other types like sockets, and define flags and predicate functions for each. Handle future needs by saying an implementation has to define suitable flags and predicate functions for any additional kinds of files. 3) Treat such entities as files. 4) Treat such entities as errors. 5) Treat such entities as not found. To me, (1) seems best. (2) is too open ended, and without a matching API to access the additional types, doesn't do much beyond (1). The others are not acceptable because they are misleading and don't match expectations. Comments? --Beman

[ptr_container] references & copyability etc (was [ptr_container] indirect_fun - do we still need it?)

11 May '05

"Thorsten Ottosen" <nesotto(a)cs.auc.dk> wrote in message news:d5tnql$2ll$1@sea.gmane.org... > what do you need the returned reference for? Just remembering rule: "Create your own classes that behave like int". isn't it? And IMO we should return reference to do these things: template<typename T> class ptr_cc_vector : public ptr_vector<T> //User's class to enable copyability { public: ptr_cc_vector(const ptr_cc_vector & that) : ptr_vector<T>(that.clone()) {} ptr_cc_vector & operator = (const ptr_cc_vector & that) { return *this = that.clone(); // :))) //Above is a bit better than //*this = that.clone(); //return *this; :)) } }; So, using ptr_container::clone is some kind of _very_ explicit copy constucting and assignment operator. Compare: a = b; a = ( b.clone() ); a(b); a( b.clone() ); and should behave like oridinal copy ctor and operator =. /////////////////////////// Let's start a new discussion about copyability :) I find ptr_cc_vector<T> very handy. Why not just enable copy ctor and assignment operator but in docs you will say explicitly that invoking copy ctor and assignment operator can be very very expensive in capital letters?? Or compromise: Add policy class By default ptr_containers are not copyconstructible, but it can be redefined if someone is willing to make ptr_containers copyconstructible template<typename T, ...., bool EnableCopyCtorAnd = DefaultBehavior> class ptr_vector; Someone, like you, will make DefaultBehavior for his ptr_containers Forbid. Someone, like me, will make DefaultBehavior for his ptr_containers Permit. IMO quite flexible, and everybody will be happy :) P.S. What's about clone_allocators - are they going to be not stateless or not? -- Pavel Chikulaev

Formal Review Request -- Interfaces
by Jonathan Turkanis 11 May '05

11 May '05

Hi, I would like to propose the proposed Boost Interfaces library, which I introduced several months ago, for formal review. (Or maybe I should say: I'd like to nominate the candidate Boost Interfaces library.) See http://www.kangaroologic.com/interfaces/ for download and documentation. The version to be reviewed will include a number of changes from the above version; in particular, about half of the features described in "Future Directions" will be implemented. However, the above version is self-contained and suitable for review, so I would like to propose it now and work on integrating the changes while it is sitting in the review queue. Jonathan

[ptr_container] indirect_fun - do we still need it?
by Pavel Chikulaev 11 May '05

11 May '05

Thorsten, Now, when we got rid of ptr_iterators, we don't need indirect_fun, do we? At least as part of ptr_container library? P.S. About copyability: may be then provide some cloning mechanism like: ptr_vector<int> a; ptr_vector<int> b(a.clone()); b = a.clone(); Where ptr_vector<T>::clone doesn't create clone immeadiately, but returns some object that refers to this, and ptr_vector<T> has ctor and assignment operator taking that object.

Re: (Another) socket streams library
by Nathan Myers 11 May '05

11 May '05

I was directed to this thread after some work to make GNU libstdc++ expose POSIX pipe semantics at the istream::readsome() level, which probably will show up in release 4.0.1. (Cf. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21286 ) It started me thinking about how to make an iostream useful when attached to a non-blocking socket. Reading this thread, it seems to me you have stepped in the same trap as most other attempts. There are many, many libraries to make various sources and sinks, including sockets, look like iostreams, but without actually being iostreams. We don't seem to find ourselves using them. For nonblocking socket support to be widely useful, it must be possible to pass such a stream to a library that takes a regular istream& or ostream& argument. This has been characterized as impossible, because iostream semantics are not compatible with non-blocking I/O. While the latter is true, the former is not. The key to the paradox is the expression "out-of-band". The owner of the stream may know things about it, and its underlying socket, that the user of the istream or ostream does not, and can act accordingly. Most particularly, the owner may know that the amount of input or output to be done will not cause any system calls to return EWOULDBLOCK. The next question is, how do we know how much I/O we can do without blocking? It is common for select not to wake up a process for writing on a socket until there is more than (say) 4K of space in the output buffer. Therefore, any use of the socket that will not produce more than 4K of output is safe. An actual TCP "out-of-band" notification from the other end may help, indicating that the last written data have all arrived, proving that a full 64K of buffer space awaits. On input, we must ensure that our override of streambuf::underflow is satisfied by a short read, and that the user of the attached istream will be satisfied with what it actually finds, and won't loop trying to get more. These conditions seem awfully restrictive, but there remain a large class of problems for which they are not *too* restrictive. What remains is to identify and package up all the usable out-of-band notification mechanisms associated with sockets, and try to achieve some abstraction and perhaps even (who knows?) portability.

parameters library and rvalue pitfall
by David Abrahams 11 May '05

11 May '05

I just added an index_result metafunction that was requested during the review, for getting the result of a named parameter lookup, possibly with a default or a lazy default. Whereas previously, you would write the following to implement your function with named parameters, template<class Params> void f_impl(const Params& p) { g( p[name] , p[value || boost::bind(&value_default) ] , p[index | 999 ] ); } now you have the option to write something like this: template<class Params> void f_impl(const Params& p) { typename boost::parameter::index_result< Params, struct name_>::type& n = p[name]; typename boost::parameter::index_result< Params, struct value_, double >::type const& v = p[value || boost::bind(&value_default) ]; typename boost::parameter::index_result< Params, struct index_, int >::type const& i = p[index | 999]; g(n,v,i); } The problem, which you may have noticed, is that in the latter case you may be creating dangling references to destroyed rvalues. In the case of the index parameter above, the rvalue 999 gets bound to a const reference that then *passes through* the operator[] and initializes i. Since p[index | 999] returns a const reference and not a value, i is bound directly to the original rvalue 999 which is destroyed at the end of the full expression. The question is, what should we do about this? It turns out to be surprisingly hard to write the declarations of these temporary variables so they work in all cases. For example, v had to be a const& because in one case index_result<...>::type turned out to be char const[4] and when the default is used, it's double with p[value || ...] returning a double rvalue (by value). Thoughts? -- Dave Abrahams Boost Consulting www.boost-consulting.com

[test] and bcc32 errors
by Russell Hind 11 May '05

11 May '05

Running the regression tests on boost.test with bcc32 leads to many errors like this (and also in other libs regression tests) basic_cstring_test.cpp: Error E2093 c:\Users\russell\Projects\boost-cvs\boost\boost/test/predicate_result.hpp 51: 'operator!' not implemented in type 'tt_detail::equal_impl_frwd' for arguments of the same type in function predicate_result::predicate_result(const tt_detail::equal_impl_frwd &) Any ideas what is going on?

I don't think it makes the code clearer, because it looks like a use of i rather than a declaration. I think it is very important for readability that names be declared explicitly. That is a general point. What you are proposing: for (i: vec) is especially misleading because it is inconsistent with: for (i = vec.begin(); i != vec.end(); ++i) I really don't think one should declare i and the other, not. What's wrong with: for (auto i: vec) ? -- Dave Harris, Nottingham, UK.
