[circular_buffer] some comments and suggestions
by Thorsten Ottosen 23 Jan '08

23 Jan '08

Hi Jan, #1 I was browsing through the docs in trunk. First I noticed that the default constructor has the follwoing postcondition: capacity() == max_size() && size() == 0 I find that somewhat unfortunate that it allocates a huge amount of memory. It seems to me that it is too easy to do that by coincidence. The usual rule for std containers is to never allocate by default and anticipate a call to reserve() or the first element. It also seems to me that this will create problems when the container is used in containers that might use default construction. #2 I think it would be useful to add a predicate called is_linearized(), so one can check if this property holds. Also, if this do hold, I should be able the get fast iterators to this linear segment, perhaps by calling .base() on the iterators which then simply return a pointer (I know I can get the pointers by array_one(), but I would more often need the iterators). #3 I think it would be useful to add rotate() as a member function. AFAICT, it can in many times (if not all) be much faster than std::rotate() because it can simply move a few elements and then simply adjust the iterators. -Thorsten

Boost Lib Design Question - TR1
by Jared McIntyre 23 Jan '08

23 Jan '08

I was hoping to get some of your thoughts on best practices for TR1 usage in boost libraries (maybe there is already a recommendation that I haven't seen yet). I'd like for some of the libraries I'm working on in the sandbox to use the TR1 namespace wherever possible, since this seems more future proof than using the boost namespace. I understand how to use the TR1 namespace in boost so that it uses the TR1 implementation of the compiler provider if it exists, or the version of boost if it doesn't. For libraries in boost, I don't see a really "clean" way to do this as it seems it would require the user to add an additional include path beyond just the standard boost path (just like you do if you use it outside) to use my library. Is anyone trying to code their boost library to the TR1 namespace? How are you doing it? Thanks, Jared

I do think it would be a good idea if things that were identified as critical fixes were made more broadly visible. I venture to guess that a lot of people on the mailing list look at the Boost home page for updates fairly infrequently. Chad

[math - quaternions, octonions] Template parameter
by Adam Badura 22 Jan '08

22 Jan '08

The template parameter may be something else then "float", "double" or "long double"? If no then I think the documentation should state it clear and it seems to me that it does not at all. (From what I recall specification of std::complex for example explicitely prohibits other specializations then those three types.) Why all functions take parameter T as "T const&" even in specialization and not boost::call_traits<T>::param_type which would be most probably (so I susppect) non reference type? Adam Badura

[random] uniform_real & uniform_01: is the implementation still buggy?
by Thorsten Ottosen 22 Jan '08

22 Jan '08

Hi, These two classes are marked with the following note: "Note: The current implementation is buggy, because it may not fill all of the mantissa with random bits." What is the practical effect of this bug? Are there any plans to debug it? Thanks -Thorsten

[test] Patch for Apache stdlib?
by John Maddock 22 Jan '08

22 Jan '08

Is there any reason why this patch: http://svn.boost.org/trac/boost/ticket/1542 can't be immediately applied to the Trunk? BTW <eh.h> is documented by MS as being the *required* header in order to use _set_se_translator see http://msdn2.microsoft.com/en-us/library/5z4bw5h5(VS.80).aspx so unless there are any objections, I'll probably apply this later this weekend.

My point is that you cannot always control the use of the default constructor ... libraries call it now and then, and it pretty much renders circular_buffer unusable with those libraries.

I guess this would be handy: void rotate( const_iterator newBegin ); precondition: newBegin in [begin(),end()). if we added a new overload taking three iterator arguments like, std::rotate(), I think it might not yield any performance improvement over the std::version. -Thorsten _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost __________________________________________________________ Sent from Yahoo!

#1 I don't agree. I tried to design the circular_buffer as close as possible to the other std containers.

Critical bugfix for Boost.Function on 12/19
by Chad Walters 21 Jan '08

21 Jan '08

I just noticed this announcement on the Boost home page: December 19, 2007 - Critical Bug in Function Library * Boost.Function in Boost 1.34.x has a bug that affects the construction of Boost.Function objects in a multi-threaded context. The problem has been fixed in the Boost trunk and for the upcoming Boost 1.35.x. To patch your Boost 1.34.x, copy the files function_base.hpp and function_template.hpp into the Boost directory boost/function. Two questions come to mind, one technical and the other procedural: 1. What other Boost libraries make use of Boost.Function in a way that might tickle this particular bug? I'd like to understand if we are being affected by this in any way and while we aren't using Boost.Function directly, perhaps we are using it indirectly. More generally, is there a good way to understand which Boost libraries are dependent on which other libraries? 2. I can't seem to find any mention of this on the user, devel, or announce mailing lists. Is there some place besides the home page where things like this get publicized? I guess I would have expected this to come through on at least of one of those three lists. Thanks for any insights. Chad

Boost.Python without Python
by Edson Tadeu 21 Jan '08

Hi, Boost.Python has a great dispatch mechanism, complete with type and methods registry, and works nice with template types (given the instantiations), and overloading -- with the extra bonus of working across shared-object boundaries. It could be very useful for many other purposes, if it were not so tied to Python. I'm thinking about multi-methods / multiple dispatching / generic factories / plug-ins. Shared objects that register extensions when loaded, e.g., register new concrete objects and new specializations for already existent methods. Is there any library that already does this? Can the non-python code be easily separated from the python-dependent code in Boost.Python? Is there already some effort to do something like this? Thanks in advance, Edson

64-bit Boost.Integer
by Phil Endecott 20 Jan '08

20 Jan '08

Dear All, Back in April 2007 I posted a patch to add 64-bit ints to Boost.Integer: http://lists.boost.org/Archives/boost/2007/04/119895.php Scott McMurray replied to say that a patch for this was already waiting and hopefully "will get applied once 1.34 is dealt with". As far as I can see, the Boost.Integer in the release branch still doesn't have this: http://svn.boost.org/svn/boost/branches/release/boost/integer.hpp What needs to be done so that this functionality is included in 1.36? Phil.

[filesystem] POSIX compliant readdir_r to fix ticket #1578
by Beman Dawes 20 Jan '08

20 Jan '08

Sun supplies both POSIX and non-POSIX versions of readdir_r, according to http://docs.sun.com/app/docs/doc/819-2243/readdir-3c?a=view. The compliant version is selected by defining _POSIX_PTHREAD_SEMANTICS. So it looks to me that the fix for ticket #1578 (which is reporting the bug that results when the non-POSIX version is used) is to define _POSIX_PTHREAD_SEMANTICS at the beginning of boost-root/libs/filesystem/src/operations.cpp. This will cause the POSIX version to be used. I don't have access to a Sun system so can't test that. There is also a small chance that the same macro is used on some other platform in a conflicting way. I'd appreciate it if someone with access to a Sun system could test this (using the program given in the #1578). If I don't hear anything in a day or so, I'll go ahead and make the change to the trunk. Thanks, --Beman

Custom deleter for ptr_vector?
by Robert Dailey 20 Jan '08

20 Jan '08

Hi, I was wondering it is currently possible to give ptr_vector a custom deleter? This could simply be in the form of a functor. If this feature does not exist, would it be hard to add? For example, you could do this: namespace boost { namespace detail { template< typename t_type > struct default_deleter { void operator() ( t_type* ptr ) { delete ptr; } }; } template< typename t_type, typename t_deleter = detail::default_deleter<t_type> > class ptr_vector { private: std::vector<t_type*> m_pointers; public: ~ptr_vector() { std::for_each( m_pointers.begin(), m_pointers.end(), t_deleter() ); } }; }

[review] General comment on boost::singleton
by Marcus Lindblom 19 Jan '08

19 Jan '08

Hi, I haven't looked into it at detail, but I've followed the discussion on the singleton's to be or no to be. I think the singleton lib is good as a boost addition, because having many different singleton implementations suck. I also think that boost should encourage good code style. Therefore, I vote for an implementation that both separates the concepts provided (i.e. safe construction, uniqueness, global access & locking). The lib should also provide some kind of unifying scheme, so that the "classic-singleton" can be achieved by applying everything. Also, I think some good motivational documentation on why the classic singleton is not a scalable idea would be appropriate, so that we could get users to think about the orthogonal concepts and whether they really do need all concepts in one go. (Many of us have found out that we only need a subset, after much pain....) Cheers, /Marcus

[flyweight] Remainder: Flyweight review will start January 21
by Ion Gaztañaga 18 Jan '08

18 Jan '08

Hi to all, Flyweight library will be reviewed January 21-30. For those interested in the library, this post contains all the information needed for the review: *Author:* Joaquín M. López Muñoz *Description:* Flyweights are small-sized handle classes granting constant access to shared common data, thus allowing for the management of large amounts of entities within reasonable memory limits. Boost.Flyweight makes it easy to use this common programming idiom by providing the class template flyweight<T>, which acts as a drop-in replacement for const T. *Online docs:* http://tinyurl.com/2sstyr http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/index.html *Download:* http://tinyurl.com/hrdm6 http://www.boost-consulting.com/vault/index.php?&direction=0&order=&directo… *Notes:* 1) We've seen some suggestions in the mailing list for Flyweight. Joaquín has nicely explained a couple of issues that we'd like to address/discuss in the review: http://tinyurl.com/33ghtf http://svn.boost.org/svn/boost/sandbox/flyweight/libs/flyweight/doc/review_… 2) Flyweight needs Boost 1.35 elements because the library depends on libraries like Interprocess for some features/tests. Since SVN snapshot tarballs seem to be missing these days, those who want to try flyweight can download a working SVN-HEAD snapshot here: http://igaztanaga.drivehq.com/boost_trunk.tar.bz2 3) Serialization tests won't work. This feature is expected to work when some new features (discussed in the mailing list between Joaquín and Robert Ramey) are added in Boost.Serialization. Those are expected for Boost 1.36. Regards, Ion

[smart_ptr] shared_ptr documentation inconsistency
by Frank Mori Hess 18 Jan '08

18 Jan '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The default shared_ptr constructor, which creates an empty shared_ptr, gives "use_count() == 0" as a post condition. However, the documentation for use_count says it returns "an unspecified nonnegative value when *this is empty". I'd like it to return 0 for an empty shared_ptr, as that appears to be the only way to distinguish an empty shared_ptr from one sharing ownership of a null pointer. - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHkRr05vihyNWuA4URArScAKCpSzE1iBEP02fn5GJhs3n/rwoItwCgkAxf uRlugdHTVX9TIsZH5swMy70= =9uJe -----END PGP SIGNATURE-----
