[random] failure of random_test on Red Hat Linux 2.6.9 ia64
by Boris Gubenko 13 Jan '08

13 Jan '08

Boost.Random library test random_test fails on linux_ia64_gcc: see <http://tinyurl.com/32hqlu> . It fails with the similar errors on Sandia-pathscale: see <http://tinyurl.com/2va9tz>. Both platforms are Red Hat Linux 2.6.9 ia64: . linux_ia64_gcc is Red Hat Linux 2.6.9-42.EL . Sandia-pathscale is Red Hat Enterprise Linux 2.6.9-34.0.2.ELsmp The test does NOT fail on Sandia-gcc-64 which is a Red Hat Enterprise Linux 2.6.18-8.el5. x.cpp below is a reduced reproducer. It passes on every platform I tried it on, including Debian GNU/Linux ia64, except Red Hat Linux 2.6.9-42.EL. On the latter, it fails for long double which is how the original test random_test fails on linux_ia64_gcc. On the platforms where it passes it outputs: *** testing float *** g = 1.353399e+00 g2 = 1.353399e+00 *** passed *** *** testing double *** g = 1.353399e+00 g2 = 1.353399e+00 *** passed *** *** testing long double *** g = 1.353399e+00 g2 = 1.353399e+00 *** passed *** On Red Hat Linux 2.6.9-42.EL it outputs: *** testing float *** g = 1.353399e+00 g2 = 1.353399e+00 *** passed *** *** testing double *** g = 1.353399e+00 g2 = 1.353399e+00 *** passed *** *** testing long double *** g = nan g2 = 1.000000e+00 *** failed *** The comment in explicit-failures-markup.xml for random_test for intel-linux-9.0 toolset says: Reported to Intel as issue 409291, and confirmed as a problem. Probably this relates to a specific Linux-Kernal or GLibC version." I'm wondering: is this problem specific to a Linux Red Hat 2.6.9 ia64 Kernal or GLibC version on this platform?

Perfect hashs are a _very_ fast alternative to sequenced if/else if chains. The beauty of this is, that it is possible to generate perfect hashs for any type of key, not only for integer values, which again is of particular interest in dynamic switch scenarios. And I'ld be happy to help with this. Regards Hartmut

Oh, perhaps I'd like to ask a review extension. If Steven can reply to my concerns and is willing to address them, I might still change my vote to a yes. I really need this facility now!

Switch library review - summary of discussion so far
by Stjepan Rajko 12 Jan '08

12 Jan '08

I will try to summarize the discussions happening so far on the Switch library under review - maybe this will be helpful to those considering joining the discussion and submitting a review. * Documentation All reviewers have noted that the documentation could be improved - e.g., additional examples, performance stats, as well as more explanation of the types involved and how they are used. * Return type Tobias Schwinger suggested that the return type should be specified explicitly in the switch_ call, rather than inferring it from the function object, and this is now a part of the recent designs being discussed. Joel de Guzman also suggested that if a version of switch_ should infer the return type, that return type should be a Boost.Variant of the types returned by each of the cases. * Default default behavior If the default behavior is left unspecified, switch_ should invoke the default constructor of the return type in the default case, rather than throwing an exception. This was suggested by Tobias Schwinger after the issue was raised by Dan Marsden. Alexander Nasonov has also indicated that a throwing default case can cause inefficiency, even when it is guaranteed not to be invoked. * Fall-through Alexander Nasonov pointed out the lack of fall-through capability in the submitted implementation. Fall-through has been incorporated into the recent designs being discussed. * Allowing void-returning function objects for the default case with a non-void returning switch Tobias Schwinger mentioned the possibility of allowing default case function objects of void return type even when the switch return type is non-void, as long as the function object call does not return. This would be useful, for example, if the function object is guaranteed to throw. There is still some discussion on whether determining if the return type is void can be done efficiently. * Design There has been a lengthy discussion on the underlying design of the library, what it should offer, and whether the name of the library is appropriate. There are two types of designs that have been put forward as being appropriate and/or necessary for a Boost.Switch library. On one hand, there is the submitted design (labeled "A" in recent postings), which takes the switch cases in an MPL sequence and a single function object containing implementations of all cases. Joel de Guzman has proposed another design (labeled "B"), in which the switch cases are specified separately and allow a different function to be used for each case. Design "A" is better suited for situations in which the number of cases is determined by a compile time constant, while "B" is more appropriate for many use cases, and provides more flexibility and a more familiar syntax. It seems that a consensus has been reached that this library could offer either both interfaces in different layers, or an interface that can be used in different ways for different uses (based on a common concept capturing case sequences). (Apologies if I have missed or misinterpreted something) More reviews/votes would be extremely welcome! Regards, Stjepan

[Range] Misc comments
by brass goowy 12 Jan '08

12 Jan '08

The Intro (intro.html) says, "Below are given a small example..." I think "Here is a small example..." would work. On that same page and other pages this is found: "Warning: support for null-terminated strings is deprecated and will disappear in the next Boost release (1.34)." utility_class.html says, "Recall that many default constructed iterators are singular..." I didn't find other uses of the word singular in the documentation and am not sure what you mean. Are you saying they are not meant to be range endpoints? In the section on portability it says: "Notice also that some compilers cannot do function template ordering properly. In that case one must rely of range_result_iterator and a single function definition instead of overloaded versions for const and non-const arguments." Probably that should be "rely on range_result_iterator..." The history and acknowledgement page says, "The library have been under way for a long time..." Should be, "The library has been under..." In iterator_range.hpp a range is often declared with the name 'r' and then there is code like r.begin and r.end. In my opinion those are distractingly similar to rbegin and rend. I think something like rg.begin and rg.end would be an improvement. I think the "sub" in the class name sub_range is kind of misleading. The documentation has the following: "Imagine that we have an algorithm that searches for a sub-string in a string. The result is an iterator_range, that delimits the match. We need to store the result from this algorithm. Here is an example of how we can do it with and without sub_range std::string str("hello"); iterator_range<std::string::iterator> ir = find_first( str, "ll" ); sub_range<std::string> sub = find_first( str, "ll" );" The docs also say, "The iterator_range class is templated on an Forward Traversal Iterator and should be used whenever fairly general code is needed. The sub_range class is templated on an Forward Range and it is less general, but a bit easier to use since its template argument is easier to specify. The biggest difference is, however, that a sub_range can propagate constness because it knows what a corresponding const_iterator is." The sample code that has a sub-string with either an iterator_range or sub_range and the description of the two classes don't give much basis for sub being in the name. In that last paragraph I quoted, there are two places where it says, "an Forward." I think those should be "a Forward." And swapping "is" and "however" in the last sentence would make it easier to read. I didn't find anything about serialization in the docs. iterator_range has an operator<<, but understandably no operator>>. Do you plan to add something in this area? iterator_range<list<int>::iterator> it_rng; oarch << it_rng; // would need to send the size .................... vector<int> vec; iarch >> vec; That seems useful.

XML
by Adam Badura 11 Jan '08

11 Jan '08

It seems to me that Boost lacks "typical XML parser" (by that I mean something offering DOM and SAX parsing as well as validation and maybe some other features). I did not look at serialization that much but I suspect that it does not offer such properties. Why is that? Any technical reasons? Or maybe "political" reasons? Or perhabs simply no one did it?
