This is due to tickets #9279/#8750 not being merged to release from trunk. Robert sent me a direct email saying "See my previous post on this thread to see why we're stuck here." but I've not been able to figure out to what he's referring. I think he was referring to this email: On Oct 31, 2013, at 9:44 AM, Robert Ramey <robertmacleranramey(a)gmail.com> wrote: > I've been trying to get these changes in. I grouped a number of the changes into one batch. I group them because it takes me a long time to test any changes. The fixes seemed simple, but to no one's surprise, they turned out to have some unexpected wrinkles. Right now I'm pending an answer to my recent question on the mailing list regarding TYPE_TRAIT deprecation. Once that gets done I would be ready to merge the trunk into the release. I don't think things are going to fall into place before 1.55 release though. It doesn't sound to me like he's ready to put those changes out into a release at this time. -- Marshall

[endian] status?
by Michael Marcin 04 Nov '13

04 Nov '13

I need to read/write some structs as binary data over an asio tcp socket and convert host<->network byte order. IIRC the endian library was supposed to clean this process up substantially but I can't find it. I thought it passed review years ago but I could be misremembering.

I agree that many Boost libraries are impractical with exception handling disabled, but there is no harm done in supporting BOOST_NO_EXCEPTIONS via boost::throw_exception, since its specification does not allow it to return. -- Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode

I wonder how useful supporting exceptions disabled is in recent years? Most recent C++ code assumes throwing exceptions works, and even games consoles which traditionally were very anti exceptions are beginning to weaken on this [1]. I also note that the C++ 11 standard library does a lot more exception throwing than the C++ 03 standard library, so it would surely be harder use C++ 11 with exceptions disabled. All this said, LLVM used to not use exceptions nor RTTI, and could be compiled with both disabled. No idea if this is still the case. Either way it was/is an interesting choice by a large, modern, non-embedded C++ use case. [1]: http://www.gamedev.net/topic/639123-portable-use-and-disabling-of-exceptions Niall

Concatenating int value to string ..??
by Rahul Mathur 02 Nov '13

02 Nov '13

All, I wish to have string (combination of string value and int value) which increments until 100. The code is as below - --- #include <iostream> #include <cstdlib> #include <string> #include <boost/lexical_cast.hpp> using namespace std; int main() { std::string TID = "Apple"; int TagID = 01, Value = 000 /* 100 IDs*/; std::string TagName, TagInitial, TagUId; TagName = TID + boost::lexical_cast<std::string>(TagID); // Should be as -> Apple01 TagInitial = TagName + boost::lexical_cast<std::string>(Value); // Should be as -> Apple01000 int i = boost::lexical_cast<int>(TagInitial) + 1; // Should be as -> Apple01001 TagUId = boost::lexical_cast<std::string>(i); std::cout << "Tag ID .." << TagUId << endl; } I get below error message - -- terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast> >' what(): bad lexical cast: source type value could not be interpreted as target Aborted (core dumped) -- Any clue? ~ Thanks!!

[Trac] Catch-22: Captcha Errors on legitimate submissions
by Jim Bell 01 Nov '13

01 Nov '13

I had a ticket attachment and comment both rejected from a "captcha error," so I decided to open a Trac ticket on the captcha mechanism itself. But guess what? THAT ticket was also rejected by the captcha error. Catch-22! So I'm posting it here. I get: -------------------------------- Captcha Error Submission rejected as potential spam (StopForumSpam says this is spam (username)) Trac thinks your submission might be Spam. To prove otherwise please provide a response to the following. -------------------------------- But there's nothing following to which to provide a response. Is it mis-configured?

[modularization] Dependency to Boost.Exception unavoidable?
by Daniel Pfeifer 01 Nov '13

01 Nov '13

2013/11/1 Peter Dimov <lists(a)pdimov.com>: > > ->exception is unavoidable because of throw_exception. I think `throw_exception.hpp` belongs to Boost.Utility for two reasons: 1. That file is older than Boost.Exception. 2. It introduces a *conditional* dependency to Boost.Exception. When I provide an implementation for `throw_exception` and/or define BOOST_NO_EXCEPTIONS/BOOST_EXCEPTION_DISABLE accordingly, I would expect *not* having a dependency to Boost.Exception. -- Daniel
