[1.34] Regressions
by Thomas Witt 13 May '06

13 May '06

Hi, The following libraries show fails across almost all platforms in the 1.34 regression tests concept_check io mpl ptr_container python wave I would be thankful for a short update on the reason and plans for mitigation. AFAICS this has to be dealt with before we even think about a Beta release. Thanks Thomas Release Manager -- Thomas Witt witt(a)acm.org

[typeof] Limitations in BOOST_TYPEOF_NESTED_TYPEDEF for VC8.0
by Peder Holt 13 May '06

13 May '06

It turns out that BOOST_TYPEOF_NESTED_TYPEDEF has a problem when used inside functions on VC8.0 (possibly other compilers as well) This is because BOOST_TYPEOF_NESTED_TYPEDEF internally defines a member template: struct a { template<typename T> struct b{ }; }; VC8.0 doesn't handle this (error C2892: local class shall not have member templates) It is possible to avoid this problem, but this would cripple BOOST_TYPEOF_NESTED_TYPEDEF because it would reintroduce the BOOST_TYPEOF_LIMIT_SIZE limitation on the expression complexity. The alternative is to disallow NESTED_TYPEDEF inside functions, and write a note on this in the docs. Is this acceptable? Regards, Peder

Proposal: formal update review
by Fernando Cacciola 12 May '06

12 May '06

Given the recent "incident" about users complaining about updates to boost and the fact that we have a wounderful METHOD that gave us so much respect and popularity, I'd like to propose something that's been in my mind for quite some time. The very high quaility of boost libraries is due to the so-called BOOST METHOD (I just coined the term, but how I like it :): the managed and peer-reviewed acceptance process. But there is a "hole" in this method, once a library is accepted the mantainer can do whatever it pleases with it. Of course we all assume and expect the maintainer to keep its hight quality, but this is a deviation from the basic "peer-reviewing is a requirement" principle. If the assumtion here were grounded we could just as well accept libraries directly because we trust the good jugdment of the author; but we don't, and there lies our "credibility". I really think is time to come up with a "direct-update" vs "managed-update" policy. The policy would define which updates can be directly executed by the library mantainer and which need a "formal update rewiew". Naturally, the formal update review should follow the same rules as the formal acceptance review. At the very least, interface-breaking changes should require a formal update review IMO. What do you all think? -- Fernando Cacciola SciSoft http://fcacciola.50webs.com/

interest in patience sorting/longest increasing subsequence lib?
by Vassilii Khachaturov 12 May '06

12 May '06

Dear boost developers, would there be interest in a library implementing the patience sorting/ longest increasing subsequence(s) recovery/length measurement? I do have some preliminary code (which is presently GPL but of course can be released under the boost license as well), which deals with what I myself need to compute in the <subj>, available off http://www.tarunz.org/~vassilii/pub/c++/ (Maybe it's not worth a separate library, but should go into a larger library for whatever sorting-related algorithms, along with the bucket sorter?) I'd be happy to make the code more generic, add the docs, more tests (I actually have more regression tests available), add the concept checking/archetypes, and implement more things beyond what I have already done, but obviously if you folks don't feel that longest increasing subsequences/patience sorting is too narrow a domain to be worth depositing it into boost. Regards, Vassilii

[wave] ifndef/ifdef callbacks
by Felipe Magno de Almeida 12 May '06

12 May '06

Hi, I see that there are some hooks for appending callbacks for certain situations in the preprocessing. I think this is great. But, I would like to know if it is possible for the user to know when the preprocessor is evaluating an preprocessor conditional, and to know what the condition is. And to fork the preprocessing to when the condition is met and when not. Thanks, -- Felipe Magno de Almeida
