[type_traits] Big changes in develop
by John Maddock 30 May '15

30 May '15

A heads up that the "Version2" rewrite of type traits is now in develop. There's still lots to do - more PR's will happen over the coming weeks to remove obsoleted code from other libraries (and quash the warnings that they'd otherwise generate). The docs also need a major update. In the mean time please do shout loudly if there are any regressions caused by this change. Thanks, John.

[type_traits][units] migrating from ice_and
by Jürgen Hunold 28 May '15

28 May '15

Hi! I've noticed that boost/type_traits/detail/ice_or.hpp and boost/type_traits/detail/ice_and.hpp have been deprecated. Both headers are used as an implementation detail in boost/units/scaled_base_unit.hpp, now resulting in lots of warnings: In file included from .../boost/units/scaled_base_unit.hpp:20: .../boost/type_traits/detail/ice_or.hpp:17:10: warning: NOTE: Use of this header (ice_or.hpp) is deprecated [-W#pragma-messages] # pragma message("NOTE: Use of this header (ice_or.hpp) is deprecated") Question: Is there a known migration path from type_traits to what? MPL? Or am I better off copying both files to Boost.Units and be done? Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold ! * voice: ++49 4257 300 !

[testing][teeks] MSVC-14 errors about MSPDB140.DLL
by Andrey Semashev 27 May '15

27 May '15

Hi, All tests for Boost.Log (and I suspect any other built libraries) on MSVC-14 are failing because of this error: LINK : fatal error LNK1101: incorrect MSPDB140.DLL version; recheck installation of this product See here for example: http://www.boost.org/development/tests/develop/developer/output/teeks99-08f… Could this be fixed?

[typeof] Weird VC++ compiler bug
by Edward Diener 27 May '15

27 May '15

I discovered a strange VC++ bug using Boost.typeof. I am not posting this to rag VC++ but wondering if there is some known workaround in Boost or in Boost.config. #include <boost/typeof/typeof.hpp> template <class T> struct dereference { typedef BOOST_TYPEOF_TPL(*T()) type; }; int main() { } Compiling this with VC++12 gives: test_vc_type_of_indirection.cpp(6) : error C2100: illegal indirection test_vc_type_of_indirection.cpp(7) : see reference to class template instantiation 'dereference<T>' being compiled Notice that I am not even instantiating 'dereference'. But if I write: #include <boost/typeof/typeof.hpp> template <class T> struct dereference { void afunction() { typedef BOOST_TYPEOF_TPL(*T()) type; } }; int main() { } all is well, for all the good it does me. BOOST_TYPEOF_TPL(*T()) expands to: typename boost::type_of::msvc_typeid_wrapper<sizeof(*boost::type_of::encode_start(*T()))>::type and if I substitute this directly the same results occur. I can report this to the VC++ bug tracker but wanted to see if this is a known problem with VC++ in Boost, some weird error for which maybe Boost has some workaround syntax.

Fwd: Binary Region Differentials
by Kenneth Adam Miller 27 May '15

27 May '15

Suppose I have a rather huge binary region. Transferring it by any means is an expensive operation. But changes to it will only be some fraction at worst case as large as the binary region itself, but in practice will typically be regional byte blobs, mostly not more than a single kilobyte long.. Is there any data structure that already handles this, where I could say, have every instance start off from the original binary region, and calculate what any other instance of that data structure has by "applicating the deltas"?

Aho - Corasick String Search (for searching multiple patterns) Interface
by meghana madhyastha 26 May '15

26 May '15

Hi, In some of my previous mails I had suggested that the Rabin Karp and Aho - Corasick string search algorithms be implemented as a part of the Boost algorithm library. This is primarily because these algorithms perform well for searching for multiple patterns. The Aho - Corasick algorithm works by building a trie (a tree with each node corresponding to an ASCII character) of the patterns strings and traversing the trie to search for the pattern in a given text. Additionally, the Aho - Corasick introduced the concept of "failure pointer/failure node" which is the node to be traversed when there is a mismatch. For more information: http://en.wikipedia.org/wiki/Aho%E2%80%93Corasick_string_matching_algorithm The interface I propose is as follows. 1. The input of the patterns should be strings within a *container*. This is because these algorithms are primarily used for multiple pattern searching. The user can input pointers/iterators to the first and last pattern . The final output which is returned is a container with each pattern and a iterator/pointer to their occurrences (There are multiple patterns so just returning an iterator/pointer to where the patterns first occurs in the pattern will not suffice). 2. Just like the previous string searching algorithms that have been implemented in Boost, there can be an object based interface as well as a procedure based interface. In the object based interface, the trie is constructed and the failure nodes are computed in the constructor (while creating the object). The user can then search the text using the operator(). template <typename patIter> class aho_corasick { public: aho_corasick(patIter first, patIter last): pat_first(first), pat_last(last), head(std::shared_ptr<trie_node>(new trie_node)) { //first and last are pointers/iterators to the first and last patterns in the container gotoFn(head); failureFn(head); } ~aho_corasick () {}; template <typename corpusIter> corpusIter operator ()(corpusIter corpus_first, corpusIter corpus_last) //Note: using the same notation as used in the other search algorithms. Corpus- refers to the text to be searched. I've implemented this and would like to get feedback/suggestions on the code as well as the interface. Where should I put up the code for it to be reviewed ? Thanks, Meghana
