[boost] [date_time][thread][string][python][mpi][typeof][function_types] License links in copyright comments
by Daniel James 25 Feb '08

25 Feb '08

Hello all, I've prepared my patches to fix several links to the copyright files. There's a lot of changes, so I've put the patches on the web instead of attaching the patches. I've got three separate patches for fixing different errors. If there are no objections I'll commit them to trunk and release in a few days. First patch is for headers which link to the non-existant LICENSE-1.0. It touches the date time, thread and string algorithm libraries: http://unordered.nfshost.com/x/copyright1.patch The next one fixes links 'http:#www.boost.org/LICENSE_1_0.txt' which seems to be a search and replace error when converting C++ header comments to python. This one is for the python and mpi libraries. http://unordered.nfshost.com/x/copyright2.patch Finally there are a handful of links of the form http:/\/www.boost.org/LICENSE_1_0.txt. These are in the typeof and function types libraries. http://unordered.nfshost.com/x/copyright3.patch There's another link of that form in the script 'libs/typeof/tools/preprocess.pl' but I left it alone as it might be correctly escaped.

Very problem oriented and helping to abstract the platform specifics. * What is your evaluation of the implementation? I didn't look at the code in detail. * What is your evaluation of the documentation? Sufficient. * What is your evaluation of the potential usefulness of the library? Very useful. In fact Joel and I are using the floating point classification and sign-bit routines in SpiritV2 (for both, parsing and generation), and it turned out to be a huge time saver for us. * Did you try to use the library? With what compiler? Did you have any problems? Yes, SpiritV2 is using it. We tried with different versions of gcc, intel and msvc (mainly on windows) * How much effort did you put into your evaluation? Essentially no extra time. I'm reporting what I've learned while writing the Spirit code. * Are you knowledgeable about the problem domain? Using this library helped me to understand some of the problems in this domain. I'm not considering myself to be an expert, though. * Do you think the library should be accepted as a Boost library? Definitely, yes. Regards Hartmut

[Math Toolkit] cdf and pdf of infinity
by Johan Råde 22 Feb '08

22 Feb '08

Hi John, I'm using the Math Toolkit in a statistics app. It works great; you have have done a fantastic job. I minor suggestion: Why not let pdf and cdf accept infinity and negative infinity when the corresponding limits exist? --Johan

[1.35.0] Release candidate process
by Beman Dawes 22 Feb '08

22 Feb '08

There is a seemingly endless set of improvements to *could* be made to 1.35.0. But I think that it is time to try to identify any showstoppers, fix those, and defer everything else to the next release. Because we now build release branch snapshots daily, the process of issuing release candidates is a bit different than in the past. The daily release branch snapshots are in effect the release candidates. So I guess the only thing the release manager has to do is create an RC_whatever tag, rename the current files on the ftp site, and post an announcement. Unless anyone feels a different procedure should be used, I'll go ahead and do that in the next couple of days. For the links to 1.35.0 release related material, including the current snapshot, see http://beta.boost.org/development/testing.html#Snapshots. --Beman

Is more/getting_started.rst obsolete?
by Rene Rivera 22 Feb '08

22 Feb '08

I'm putting some final touches on the docs and web site for release and I was rebuilding the getting started docs. But I'm confused... There's a more/getting_started.rst which one would think corresponds to more/getting_started.html. But currently more/getting_started.html is a redirect to more/getting_started/index.html, and rebuilding from the more/getting_started.rst obliterates the redirect with a bunch of content. Is more/getting_started.rst obsolete? -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org (msn) - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim,yahoo,skype,efnet,gmail

[function] boost::function<>::swap() can throw

What happened to boost-root/index.htm?
by Beman Dawes 21 Feb '08

21 Feb '08

boost-root/index.htm has been deleted and boost-root/readme.html has been added. Is the intent that readme.html becomes the new home page? That would be a breaking change for the many user's who have links on their own pages to Boost's index.htm in their local installation of Boost. "index.htm" was an unfortunate choice of name, so I think the current reorganization would be a good time to change the home page to "index.html". But we will still need "index.htm" to avoid breaking user links (not to mention our own links!), although it can just redirect to "index.html". We could also have a "readme.html" that redirects to "index.html", although it seem unnecessary to me. --Beman
