  The release script doesn't need to copy images and css - because that's now done in the jamfiles. Also tweak the shell script a tad bit.

Daniel James 55acb6d733 Merge new changes to unordered & hash. 
- Unordered tests can run lightweight test or Boost.Test (at least
   theoretically).
 - Workaround Open BSD's incorrect numeric_limits.
 - Move the hash extensions in their own file.
 - Various small improvements to the unordered docs.
 - Fix some unordered examples.

 2008-03-24 17:03:15 +00:00
Daniel James b2d85ea76b Remove the _fpclass code from floating point hash. 
[SVN r42416]
 2008-01-02 18:08:43 +00:00
Daniel James f0f19cd688 Only suppress warning for Visual C++ 8 and later. Refs #1509 
[SVN r41866]
 2007-12-08 12:24:36 +00:00
Daniel James 210ed051dd Try to suppress a Visual C++ warning. Refs #1509 
[SVN r41864]
 2007-12-08 11:04:40 +00:00
Daniel James b0d0ec44ec Don't use fpclass because it causes a warning for long doubles. I don't know if the warning is vaild here - but I don't want to disable it as it's useful for checking other function calls. 
[SVN r41057]
 2007-11-13 11:51:23 +00:00
Daniel James 035b91bdcd New algorithm for hash floating point numbers. 
[SVN r40264]
 2007-10-21 08:36:47 +00:00
Daniel James ee28cdbcd5 On Cygwin use a binary based hash function for floating point numbers, as 
Cygwin doesn't have decent floating point functions for long doubles.


[SVN r39694]
 2007-10-05 09:46:22 +00:00
Daniel James db8825c7d1 Change a comparison in the float hashing code, which can cause a warning on 
gcc. Although the warning doesn't currently turn up in this branch, it could
be caused quite easily. Originally reported in:

http://lists.boost.org/Archives/boost/2007/08/126084.php


[SVN r38883]
 2007-08-24 02:01:47 +00:00
Daniel James 2ae3f472c1 Remove the errno check when hashing floating point numbers. It's not really 
needed and was causing problems on the Microsoft Windows Smarthone Edition
platform. Fixes #1064.



[SVN r38877]
 2007-08-24 01:11:33 +00:00
Daniel James 33643fd6b3 Update the copyright in the hash library. 
[SVN r38876]
 2007-08-24 01:05:36 +00:00
Daniel James aa7a824c6d Copy hash library from 1.34.1 over trunk. 
For the first merge with the release branch, I only want to include some of the
changes I've been working on (fixes and some trivial changes), so I'm starting
again from 1.34.1.


[SVN r38873]
 2007-08-24 00:42:19 +00:00
Daniel James 567290d703 Avoid a comparison with zero warning on gcc when compiling with -Wextra. 
[SVN r38679]
 2007-08-15 14:35:39 +00:00
Daniel James 27d2c57873 Update copyright on hash headers. 
[SVN r37801]
 2007-05-27 09:07:09 +00:00
Daniel James 3ebd297644 Rename hash_detail::float_limits => hash_detail::limits, since it's also used 
for integers in the tests.


[SVN r35559]
 2006-10-11 18:58:40 +00:00
Daniel James 8aa2b19669 Only use the float.h macros on OpenBSD, it seems that on FreeBSD numeric_limits is actually a better option. 
[SVN r35501]
 2006-10-05 21:22:56 +00:00
Daniel James 64da418fb2 Fix a typo. 
[SVN r35500]
 2006-10-05 21:21:43 +00:00
Daniel James a60b7d12f3 Remove checks for float macros, I was being over-paranoid. 
[SVN r35349]
 2006-09-26 23:28:34 +00:00
Daniel James a08d42c10f Attempting to work round the dodgy std::numeric_limits<long double> on 
some BSDs.


[SVN r35345]
 2006-09-26 20:35:58 +00:00
Daniel James 46654045d7 Comment out an assert which is giving bogus failures. On platforms where it isn't possible to detect NaN or infinity the full hash computation is performed on them. For NaN the result doesn't matter (since NaN != NaN), for infinity it should always give the same result), so the calculation works but unfortuanately, I don't know how to correctly check that v is what I expect in the assertion. 
I could use a different hash function when I don't have fpclassify/fpclass but that shouldn't be necessary.


[SVN r34490]
 2006-07-09 22:50:43 +00:00
Daniel James 572d82713b Update copyright details. 
[SVN r34390]
 2006-06-25 09:59:05 +00:00
Daniel James 4283c17309 Avoid a warning on Visual C++ 
[SVN r34329]
 2006-06-17 21:22:51 +00:00
Daniel James d8c636ef9f Tweak the float hashing algorithm to perform fewer calls to ldexp for some 
types and possibly generate a better hash value.


[SVN r34273]
 2006-06-11 15:29:09 +00:00
Daniel James 82cca89876 Improve support for floating point types with radix != 2. 
[SVN r34272]
 2006-06-11 14:52:55 +00:00
Daniel James 58aec4566a Don't use fpclassify for hashing on OS X. 
[SVN r33875]
 2006-04-30 19:16:08 +00:00
Daniel James e592b7f057 Update the copyright comments in the hash headers. 
[SVN r33370]
 2006-03-18 15:54:53 +00:00
Daniel James fa8ce5ac40 Use _fpclass and fpclassify on less platforms. Hopefully will use them more widely after the release. 
[SVN r33047]
 2006-02-21 00:12:36 +00:00
Daniel James b36cac82c3 In hash_float, only use _fpclass on Visual C++, I'll find out about other compilers later. 
[SVN r32833]
 2006-02-11 21:15:15 +00:00
Daniel James 0a1800f9f8 A couple of workarounds for Digital Mars. 
[SVN r32786]
 2006-02-09 19:22:54 +00:00
Daniel James 1cf74208aa Use fpclassify/_fpclass for the hash function on compilers where I 
know it's available.


[SVN r32782]
 2006-02-09 19:11:09 +00:00
Daniel James 5a5bbbf403 Make hash_float.hpp use its own combine function. This serves two purposes: 
1. hash_float is no longer dependent on the main hash header.
2. hash_float(0) == 0 which makes it easier to implement hash<complex>(),
although this might lead to users assuming that it can be expected even though
it isn't part of the documented interface.


[SVN r32780]
 2006-02-09 19:07:33 +00:00
Daniel James b2be632311 Move include errorno & limits from hash.hpp into hash_float where they should be. 
[SVN r32777]
 2006-02-09 18:55:35 +00:00
Daniel James 81483cc533 Move the float hash function into its own header.
