Endian library - request for comments
by Beman Dawes 03 Jun '06

03 Jun '06

Back in 1999 and 2000, there was discussion of a Boost Endian library to provided portable big and little endian integer types. I've dusted off some old code from Darin Adler, gotten his permission to use the new Boost license, and have put together a library. A zip file of the whole library is available at http://mysite.verizon.net/~beman/endian.zip The docs can be read at http://mysite.verizon.net/~beman/endian.html Comments welcome! --Beman

Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Michael Fink (… [View More]vividos) Assigned to: John Maddock (johnmaddock) Summary: [config] evc4 port Initial Comment: This patch is a port for evc3/4 targeting Windows CE. Reason for the changes in auto_link.hpp: STLport with evc4 cannot be compiled in _STLP_DEBUG mode; the compiler issues wrong ARM code and _STLP_DEBUG mode cannot be used with evc4 ARM. I also introduced a new file wince.hpp in boost/config/platform/, since the defines in the _WIN32_WCE part got too big. ---------------------------------------------------------------------- Comment By: Reece H Dunn (msclrhd) Date: 2006-06-03 20:57 Message: Logged In: YES user_id=761714 I am working on providing support for WinCE platforms by extending the BBv2 msvc.jam toolset. See http://www.reece-dunn.co.uk for the updates. I am adding the -DARM, -DWINCE, etc. as required by the platforms as well as adding -machine:ARM4, etc. to the linker.

Re: [boost] Infinite precision integer draft
by Topher Cooper 03 Jun '06

03 Jun '06

I don't think that it is that important to have unsigned_integer, but this argument against it doesn't stand up: 1) Unsigned integer is not just an arbitrary restriction on range but an important concept in its own right. Its use clarifies intent. In my opinion, for example, it is a common, though minor, programming error to use "int" rather than "unsigned int" when you intend to express cardinality of something (e.g., the size of an array). The only real justification otherwise is to … [View More]allow such practical "tricks" as testing if a decreasing index is less than 0. 2) The extra data type, assuming that the design error of deriving unsigned_integer from integer is avoided, would add complexity for boost maintainers but virtually none for users. It is, after all a logical extension of the built in types -- it takes the user all of 5 seconds to understand it, if that. Good library design is user-centric. Developer-centric design is the root of a great deal of evil. Lack of development/maintenance resources is, of course, a valid argument, but this is a completely different issue than that of the evils of unnecessary complexity. 3) Normal use of an unsigned integer type will never "try" to produce a negative result -- its not a meaningful concept, so if you play by the rules it doesn't happen. You certainly would never try to negate a cardinality (how often do you write code that says "If this string contains 27 characters then I want another one containing -27 characters?). Subtraction does have to be done with care, but in most cases the issue of subtracting a larger from a smaller doesn't come up. Subtraction generally appears, sometimes subtly so, as a computation of the size of the complement of a subset within a larger set. If you are dealing with where you would want to use unsigned integers and you unwittingly do subtract a larger from a smaller value -- if your program logic does not protect you from it -- than you better have an exception. 4) If the exceptions are exceptional than in most systems it is very much more expensive to do an explicit test than to set up to handle an exception.

[type_traits] Recent change broke serialization on Borland
by Nicola Musatti 03 Jun '06

03 Jun '06

Hallo, A recent change to remove_all_extents.hpp broke Spirit 1.6 and thus Serialization on Borland compilers. I think it should be reverted, unless Joel or Robert see a different solution. Cheers, Nicola Musatti

[wave[ Patch for samples Jamfile [.v2]
by Juergen Hunold 02 Jun '06

02 Jun '06

Hi ! I've attached a quick patch for the Jamfiles of libs/wave/samples/waveidl. Someone shortened the filename of "instantiate_re2c_lexer_string.cpp" to "instantiate_re2c_lexer_str.cpp" and forgot to adjust the Jamfiles. Okay to apply (on RC_1_34_0, too) ? Yours, Jürgen -- * Dipl.-Math. JÃ¼rgen Hunold ! Ingenieurgesellschaft fÃ¼r * voice: ++49 511 262926 57 ! Verkehrs- und Eisenbahnwesen mbH * fax : ++49 511 262926 99 !

by David Abrahams 02 Jun '06

It seems as though the OP may not be totally crazy, so we should evaluate his comments and see if the issues can be (or have been) addressed. The article is of course bad publicity for Boost, and I'd like to demonstrate responsiveness if possible. -- Dave Abrahams Boost Consulting www.boost-consulting.com

These are the submitted patches that are waiting to be integrated/rejected/whatever. Which of these are going to be part of 1.34? As you can see, we've picked up a few new ones - currently assigned to "nobody". I know that guy, and he's not very reliable, if you know what I mean. ;-) As always, if you see one that is mis-assigned, or you think that one marked "nobody" is right for you, please don't hesitate to jump in. Thank you for your cooperation! Patches per assignee: Jonathan … [View More]
