libs/iterator/doc/iterator_facade.html typo?
by Angus Leeming 13 Feb '04

13 Feb '04

libs/iterator/doc/iterator_facade.html#tutorial-example In the section "Template Arguments for iterator_facade" is the subsection "CategoryOrTraversal". I suspect that should be "CategoryOfTraversal" (s/Or/Of/). The iterator_adapter docs spell it "CategoryOrTraversal" too. Regards, Angus

If it runtime errors you could rely on "expected errors" feature. You are right for compile time errors, though one could try to ifdef part of test program. Gennadiy.

[boostbook] setup documentation minor nit:
by Ronald Garcia 13 Feb '04

13 Feb '04

Howdy, In the documentation for setting up boostbook located at: http://www.boost.org/regression-logs/cs-win32_metacomm/doc/html/boostbook.g… The path "tools/build/new" is mentioned as the location of user-config.jam. It appears that the path has since changed to "tools/build/v2". cheers, ron

1.31.1 critical update patch?
by David Abrahams 13 Feb '04

13 Feb '04

We need to fix the regressions in 1.31.0 right away. Since I don't have time to manage a release, and nobody else has volunteered to do it, I'd like to suggest that we post a 1.31.1 "critical update" patch for 1.31.0 on the website. This would save us from having to deal with a site update or making new release archives until someone can really devote the attention a full release deserves. Thoughts? -- Dave Abrahams Boost Consulting www.boost-consulting.com

broken image on the web pages?
by Ronald Garcia 13 Feb '04

13 Feb '04

Howdy, If I go to http://www.boost.org/ and select "Nightly CVS" Under "Documentation", I find a broken image in the top left corner where I would expect to see the Boost logo. I'm presuming that this page is autogenerated from boostbook? Cheers, ron

Constructing boost::posix_time::ptime from "flat" time?
by charles.crain＠ni.com 13 Feb '04

13 Feb '04

I am having a hard time figuring out how to construct a ptime from a "flat" time (i.e., some number of time units since some epoch) other than a time_t. For instance, we have a lot of software here at work that represents time as a double-precision floating point number of seconds since 1/1/1904 00:00:00 GMT. As you can imagine, any sensible number is bigger than a 32-bit integer. I would like to be able to construct a ptime something like this: ptime p(date(1904, Jan, 1), microsec(boost::int64_t(float64_time * 1000000.0)); ...or even better... ptime p(date(1904, Jan, 1), float64_time); Problem is, it seems the constructors to most time_duration types use longs, even if they use int64's internally. I can't get the above example to work with any time past 12/31/1904 23:24:12, which just happens to be 0x80000000 microseconds past 1/1/1904. Another thing I would like to do is construct a ptime from a Win32 FILETIME, which is an int64 number of 100ns intervals since 1/1/1601. Something like this: ptime p(date(1601, Jan, 1), nanosec(100 * fileTime)); Is there a better way to do this? I am using MSVC 6.0 SP5 with Boost 1.31.0. -Charles

boost::function & gcc 2.96 problem

Any news about the formal review process re-animation?
by JOAQUIN LOPEZ MU?Z 12 Feb '04

12 Feb '04

Some weeks ago it was discussed in the mailing list how to boost the review process which seemingly had stuck for quite a while. Unfortunately the discussion seemed to fade away with no definitive conclusions. Could it be possible to know what the status of the review queue is? The review schedule page does not seem to have changed since the discussion took place. I'm interested myself because I applied for formal review some time ago.

I still think a platform guru would be a useful function. This Person would run the tests on his local resources for a particular Platform and help with issues on that platform.

A single >program would cut the overhead, including the human overhead. I would strenuously disagree with this idea. In some cases it would result in a truly humongous program. When I included a test of this nature with my submission last year it was criticized for the above reason - rightly so in my opinion. There are lots of other problems besides. Suppose a test case doesn't compile - then none of the other tests are run. I'm still convinced that the problem with the release process is rooted In developer's desire to include features directly into release "heaven" Without having spent time in development "purgatory". Is_abstract and Autolib come to mind. The branch was announced approx 1 november. The autolib document is dated 26 November. Can't someone just monitor the state Of the development tree and when it looks pretty good say "We're branching today - nothing but bug fixes in the release". The current process is so Painful and takes so long that developers feel under pressure to get the Latest great feature in now because if not its going to take 6 months for The next one. Under this proposal, releases could be more frequent and In smaller increments. After all what's the point of running the tests on The development tree on a daily basis if its going to be more or less Bypassed under pressure for a release? Robert Ramey

A VC6 bug in const_reverse_iterator implementation?
by RGProlog＠aol.com 12 Feb '04

12 Feb '04

I tried to createa const_reverse iterator for the Dynamic Multi Array Library non constant object. It did not work. I then tried the same thing for Boost.Array with the same result. Which made me suspect it was the const_reverse_iterator implementation problem. Any answers? Roman Gitlin
