Re: [boost] UTF8 library - second call for informal review

UCS-2 is a subset of UTF-16, so it should be no problem. "Endianess" is something that is not covered by this library, though. ----- Original Message ---- From: gchen <chengang31(a)gmail.com> To: boost(a)lists.boost.org Sent: Tuesday, December 5, 2006 10:01:57 PM Subject: Re: [boost] UTF8 library - second call for informal review Nemanja Trifunovic wrote: > Hello everybody. > > This is the second call for the informal review of the UTF8 library. It is based on verson 1.02 of UTF8-CPP: http://utfcpp.sourceforge.net/ and you can find it at http://boost-consulting.com/vault/index.php?PHPSESSID=8j6irqkpv3reg5s1gv0lg… > > The library is stable and is being used for several months now. > Hi, The project looks very impressive. Just a question, can it convert UTF-16 in UCS-2BE formt to utf8?

Dear Robert and Johan, I too think that it would be great to have a bioinformatics library. Parts of it may ending up being quite domain specific but there are many algorithms which are also of general interest. Hamming distance & Longest common subsequence are obvious examples. HMMs and dynamic programming also have much general utility. Slightly more esoteric things (?) like MCMC, EM, various sorts of ML are becoming more common place as everyone tries to model everything (e.g. in finance). Part of the attraction of trying to do it in c++ is to see how far absolute performance can be maintained without compromising flexibility and a good design. At the moment, there is little self-contained well designed good performing code freely available for many of these routines in any language. Having it in c++ would be a major boon. Leo Goodstadt

Boost Inspection Report Run Date: 17:05:21 UTC, Tuesday 05 December 2006 An inspection program <http://www.boost.org/tools/inspect/index.html> checks each file in the current Boost CVS for various problems, generating this as output. Problems detected include tabs in files, missing copyrights, broken URL's, and similar misdemeanors. Totals: 11420 files scanned 890 directories scanned (including root) 242 problems reported Problem counts: 0 files with invalid line endings 0 bookmarks with invalid characters 3 invalid urls 175 broken links 21 unlinked files 7 file/directory names issues 1 files with tabs 0 violations of the Boost min/max guidelines 35 usages of unnamed namespaces in headers (including .ipp files) Summary:

[serialization] [msvc-7.0] test_reset_object_address
by Vladimir Prus 05 Dec '06

05 Dec '06

The test fails with: test_reset_object_address.cpp ..\boost\archive\detail\oserializer.hpp(533) : fatal error C1204: compiler limit : internal structure overflow See: http://tinyurl.com/wrtu2 Does this sound to any MSVC guru as an easily workaroundable issue? Note that this is regression -- the test appears to have worked in previous version of the library. But given that 7.0 is some transitional version, there's no point spending *too* much cycles in this. Unless a workaround is found by the end of this week, I'll mark this failure as expected. Thanks, Volodya

[signals] msvc-6.5 failures
by Vladimir Prus 05 Dec '06

05 Dec '06

There are four failures of the signals library on msvc-6.5, like this http://tinyurl.com/tc4et All are access violations on runtime. Doug, do you think you'll have the time next week to look into this? Anybody else is willing to debug the problem? If not, I don't think it makes much sense to hold a release because of problems with many-years-old compiler, so I'll just mark the failures as expected. Thanks, Volodya

[thread] Some thoughts about "atomic"
by Roland Schwarz 05 Dec '06

05 Dec '06

After having tried to learn about atomic from reading through several articles, processor specs and mailing lists, I am more confused than before. I would be glad if we could (re)start a discussion about the topic. Perhaps I am not the only one to benefit from this. Following are some things I learned, but this might be wrong, and I would appreciate clarification. Also some questions: 1) atomicity (in this specialized context) is about optimizing the pattern: enter_critical_section; do_something; leave_critical_section; by making use of processor/platform specific means. In particular in presence of multiple processors. I.e. an atomic lib is primarily about performance. 2) atomicity better would be addressed by the compiler, given a suitable memory model, than as a library. 3) Despite 2) it would be possible to write a library, but it will be hard to get processor independent semantics. E.g. there is one concept of read/write/full memory barriers or another of acquire/release semantics for SMP. 4) Does there exist a canonical set of atomic primitives, from which others can be built? E.g. given atomic_test_and_set, atomic_load and atomic_store is it possible to emulate atomic_compare_and_swap? (without use of system mutices of course.) 5) Is it worth the effort to create a library with processor independent semantics, at the price of not being optimal? E.g. by doing away with the various kinds of barriers, instead simply requiring atomicity and full memory barrier semantics for the operation? Which operations, besides load and store would be essential? Sorry if this is not the perfect list to discuss the topic, but I think boost could possibly benefit from such a library, as previous discussions let me believe. Regards, Roland

[serialization] test_variant_xml_archive
by Vladimir Prus 05 Dec '06

05 Dec '06

Robert, for all appearances, this test failure: http://tinyurl.com/y5gv7s is the problem with the test itself, not with the library. The error message is: Error E2304 ..\libs\serialization\test\test_variant.cpp 171: Constant variable '_Stz' must be initialized The problem is that I can't find that many lines in the file in question. Do you have an idea what's this variable is and how to fix it? Thanks, Volodya

Geometry/Vec lib swizzle syntax prototype

I have uploaded a small prototype that demonstrates the syntax mentioned in the thread below. It is in the Vault under Math - Geometry as swizzle_demo.zip. http://article.gmane.org/gmane.comp.lib.boost.devel/149076/match=geometry+v… Here's a small example showing its use: float4 b(1, 2, 3, 4); float4 a = b.xxxx(); // a is now 1, 1, 1, 1 a = b.wwwz(); // a is now 4, 4, 4, 3 a = b.yzzw(); // a is now 2, 3, 3, 4 a = b.wzyx(); // a is now 4, 3, 2, 1 float4 c(10, 20, 30, 40); c.yz() = b.zy(); // c is now 10, 3, 2, 40 This mimics Cg, HLSL, and GLSL syntax closely. The swizzle syntax is implemented as function calls so that it doesn't increase the size of the vector struct (important for using those structs directly for graphics API calls). The prototype code does not implement arithmetic operators for simplicity's sake, but my local copy has it implemented. This isn't meant as a full library, only a demonstration showing that the swizzle syntax can be achieved rather simply using the Boost PP and TypeTraits libraries. One item that could be changed is the multiple template parameters to the classes. In the discussion that took place during the review of Andy Little's library the prospect of heterogeneous vectors took place. In my opinion heterogeneous vectors work with little expense to the library writer and transparently to the user. It would also "just work" with Andy's Quan library, or the other Units library being developed. This is pretty off-topic for the syntax that I am demonstrating, I just wanted to mention that I hadn't removed it from this demo. It is in no way necessary, but removal would require the macros to be changed a little bit. I have only compiled using VS 7.1 and 8.0. I am by no means a PP or template guru, so I would welcome your thoughts and critiques. --Michael Fawcett
