[Serialization] this seems wrong
by Kenny Riddile 05 Dec '08

05 Dec '08

I'm somewhat inexperienced with boost serialization, so forgive me if I'm just missing something. I have a few simple classes that are all serializable. In each class's header, I have BOOST_CLASS_EXPORT( ClassName ) right after the class declaration. All of these classes are header-only, so there is no cpp. All of these classes are very similar, so the statement above is often on the same line of the file (line 21 in this case). When I include all of these headers in a single source … [View More]

[MPL] new run-time algorithm: for_all
by George van Venrooij 05 Dec '08

05 Dec '08

Hello everyone, I recently created a MPL-based run-time algorithm named "for_all" which you can find at the following location: http://tinyurl.com/5a9d9d It is based on the "for_each" algorithm. The main difference is that it traverses a sequence of sequences and constructs new sequences that are then passed to a functor. Read the article for more information. I found it to be very useful in several cases, so I wanted to share it with the community. If you have any comments or … [View More]

boost::interprocess::bad_alloc in copy ctor of slist
by Christoph Mathys 05 Dec '08

05 Dec '08

Hi! I have an object containing an interprocess slist (wrapped in a simple template) which I first construct outside shared memory. Then I want to push_front this object into a slist lying inside shared memory. And I get an interprocess::bad_alloc exception from the lists copy constructor. If I don't use the slist's copy ctor but something like this->assign(x.begin(), x.end()), the code runs through (the list was always empty in the test). I use gcc 4.2.4 on linux 2.6.24 (ubuntu 8.04). … [View More]

Breaking existing libraries
by Tomas Puverle 04 Dec '08

04 Dec '08

You may or may not have noticed a thread I started on boost.users about the breaking changes to Boost.Range. Here’s a short summary: We are currently (firmwide) using boost 1.33.1. I am in the process of trying to migrate and test some of our apps with boost 1.37. In 1.35 there was a breaking change to Boost.Range with respect to how singular ranges behave. This brings up several issues: 1) The breakage was silent. The interface stayed the same but the behavior changed, and drastically … [View More]

[graph] 'short' in bundled property throws boost::bad_any_cast
by remi.chateauneu＠gmx.de 04 Dec '08

Hi, I have a graph with a bundled property whose one of the members is a 'short'. When calling read_graphml, it throws an exception: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_any_cast> >' what(): boost::bad_any_cast: failed conversion using boost::any_cast Same problem with 'unsigned short'. With 'int' and 'long', it works.

[interprocess] maximum length for names of mutexes, memory segments etc.
by JOAQUIN M. LOPEZ MUÑOZ 04 Dec '08

04 Dec '08

A component of Boost.Flyweight called intermodule_holder internally uses some Boost.Interprocess objects with very long names intended to guarantee sistem-wide uniqueness. For instance, this is how such an internal mutex can be named (87 chars): boost_flyweight_intermodule_holder_mutex_5660_601342046_2913549788_3054690985_591945496 Alas seems like 87 chars is too much in some platforms like NetBSD: terminate called after throwing an instance of 'boost::interprocess::interprocess_exception' … [View More]

[interprocess] preparing containers
by Thorsten Ottosen 04 Dec '08

04 Dec '08

Hi Ion, Some of my students tried to use boost::circular_buffer with Boost.Interprocess allocators. Apparently the docs does not mention circular_buffer as one that is compatible with Boost.Interproccess. What do we need to do to make a container that support the special allocators? In particular, if I want to use boost::ptr_vector, then do I need to have stateful allocators (both the normal container allocator, and the clone_allocator)? Thanks -Thorsten
