Boost Regression test failures Report time: 2007-02-01T14:03:12Z This report lists all regression test failures on release platforms. Detailed report: http://engineering.meta-comm.com/boost-regression/CVS-RC_1_34_0/developer/i… The following platforms have a large number of failures: intel-linux-9.0 415 failures in 24 libraries (35 are from non-broken platforms) algorithm/string (1 of 2 failures are from non-broken platforms) bind (1) config (0 of 1 failures are from non-broken platforms) date_time (0 of 21 failures are from non-broken platforms) dynamic_bitset (1) filesystem (2 of 4 failures are from non-broken platforms) function (1) graph (0 of 2 failures are from non-broken platforms) iostreams (0 of 4 failures are from non-broken platforms) iterator (2) math (1) multi_index (0 of 1 failures are from non-broken platforms) numeric/interval (7) parameter (0 of 1 failures are from non-broken platforms) program_options (0 of 7 failures are from non-broken platforms) ptr_container (0 of 1 failures are from non-broken platforms) python (1 of 63 failures are from non-broken platforms) regex (2 of 36 failures are from non-broken platforms) serialization (0 of 215 failures are from non-broken platforms) spirit (2 of 7 failures are from non-broken platforms) statechart (0 of 2 failures are from non-broken platforms) test (11 of 22 failures are from non-broken platforms) thread (1 of 8 failures are from non-broken platforms) wave (2 of 5 failures are from non-broken platforms) Test failures marked with a (*) represent tests that failed on platforms that are considered broken. They are likely caused by misconfiguration by the regression tester or a failure in a core library such as Test or Config. |algorithm/string| regex: intel-linux-9.0* replace: msvc-8.0 |bind|

Boost.Accumulators Review
by Javier Estrada 01 Feb '07

01 Feb '07

Eric, I've the following documentation comments: In user_s_guide.html#accumulators.user_s_guide.the_accumulators_framework ------------------- Missing indeterminate article: The first sentence in The Accumulators Framework reads: "The Accumulators Framework is framework..." Should read: "The Accumulators Framework is a framework..." ------------------- Typo: cacheing for caching The sentence in the last bullet in The Accumulators Framework section reads: "...resolving dependencies between requested calculations, possibly cacheing intermediate results" Should read: "...resolving dependencies between requested calculations, possibly caching intermediate results" ------------------- Typo: calcualte for calculate The C++ comment in the code below section Passing Optional Parameters reads: // This will calcualte the left tail and my_order_variate for N == 2 Should read: // This will calculate the left tail and my_order_variate for N == 2 ------------------- Inconsistency: No hyperlink for external<> In the Accumulators Toolbox section, the table cell that contains external<> does not have a hyperlink ------------------- Typo: are for is In Extending the Accumulators Framework section, the sentence that reads: Also covered are how to control the dependency resolution of features within an accumulator set. Should read: Also covered is how to control the dependency resolution of features within an accumulator set. ------------------- Typo: explanitory for explanatory In Extending the Accumulators Framework section, the sentence that reads: Much of the above should be pretty self-explanitory Should read: Much of the above should be pretty self-explanatory ------------------- Typo: double be In the Defining a New Feature section, the sentence: The result of mpl::apply< impl, sample-type, weight-type >::type must be be the type of the accumulator that implements this feature. Should read: The result of mpl::apply< impl, sample-type, weight-type >::type must be the type of the accumulator that implements this feature. ------------------- Regards, Javier

[graph] leda_graph.hpp
by Jens Müller 01 Feb '07

Hi all, I looked at the leda_graph.hpp and made the following changes: * property map interface to the LEDA edge_array class nearly 1:1 copy of node_array stuff * adapter for non-templated 'graph' class added nearly 1:1 copy of code for GRAPH<vtype,etype> * fixed access functions (outside iterator code) to use member functions of the graph/GRAPH class see http://www.algorithmic-solutions.info/leda_manual/graph.html * replaced leda_something by leda::something (node, edge) * make iterators use 'public' LEDA interfaces see http://www.algorithmic-solutions.info/leda_manual/graph.html * implemented clear_vertex * implemented EdgeListGraph concept * edge_iterator class * edges function Still have to test them, though, and clarify copyright stuff with my boss. I have one question about leda_graph_id_map: Is the id() member function for nodes (and edges) officially defined somewhere? Jens

[thread] regressions for msvc-8.0 x64
by Roland Schwarz 01 Feb '07

01 Feb '07

I am unsure how this "regression" should be handled. Since this _is_ a new compiler it is not really a regression, but on the other hand the compilers toolset name is the same as for x32. 1) Is there a way to explicitly markup as expected to fail conditioned on x64 ? 2) I do not have yet an x64 compiler so I will not be able to implement the tss cleanup for static linking for 1.34. I'll do this later. Roland

Regression count further dropping down ...
by Roland Schwarz 01 Feb '07

01 Feb '07

Most of the issues of borland-5.8.2 and msvc-6.5 have been resolved. 1) The next major candidate seems to be: intel-linux-9.0 Anyone working on this already? 2) msvc-6.5 test library Joaquin has provided a patch for which I asked Gennadiy for permission to apply. Roland

Accumulators review
by John Maddock 01 Feb '07

01 Feb '07

This is the first part, of what will probably end up a multi-part review. First the headline - I do think that the library should be included in Boost - although I do have some reservations as noted below. This part-review covers the documentation and a few simple tests I've conducted. Later I'll try writing some accumulators so that I can comment better on the design. Documentation review ~~~~~~~~~~~~~~~~~~~ Tutorial: ~~~~~~~~~ I'm fairly sure that the whole accumulator_set_wrapper business could be completely avoided with a TR1 conforming reference_wrapper - which unfortunately we don't have in Boost just yet - none the less this may be worthwhile mentioning. The "push all the data in this sequence" idiom seems like a very common use case to me, is it not worthwhile supporting this directly via a couple of member functions: template <class It> accumulator_set& accumulator_set::push_range(It begin, It end); template <class Seq> accumulator_set& accumulator_set::push_sequence(Seq const& s); Typo in "This will calcualte the left" Statistic accumulators: ~~~~~~~~~~~~~~~~~~~~~~ Kurtosis ~~~~~~~~ This is going to confuse folks - I know it's got Paul and I into trouble already! You're returning the "Kurtosis Excess" rather than the "Kurtosis Proper". In the Math Toolkit stats functions we called these functions "kurtosis" and "kurtosis_excess", and I'd favour similar naming here, or at least a strong warning to the effect that there are multiple definitions in the literature - otherwise unwary users will get into all kinds of trouble. Differing implementations? ~~~~~~~~~~~~~~~~~~~~~~~~~~ feature_of and as_feature get mentioned in the tutorial, along with a sentence to say that there can be different implementations of the same feature, but there is no explanation of how this works, and the links to the reference pages for as_feature and feature_of are distinctly detail free :-( This all leads on to the algorithms used for the mean and variance etc: I assume that these are of the "naive" variety? Perfectly satisfactory for simple cases, but there are well known pathological situations where these fail. I'm also missing accessors for: the standard deviation, "unbiased" variance, and the unbiased (N-1) standard deviation. I realise I could write these myself, but they would seem to be common enough cases to warrant inclusion in the library. As it stands, I had to jump through hoops to get data I could compare with "known good values". BTW, I assume that there are no accumulators for Autocorrelation Coefficient calculation? Which leads on to a quick comparison I ran against the "known good" data here: http://www.itl.nist.gov/div898/strd/univ/homepage.html The test program is attached, and outputs the relative error in the statistics calculated. Each test is progressively harder than the previous one, the output is: PI data: Error in mean is: 0 Error in SD is: 3.09757e-016 Lottery data: Error in mean is: 6.57202e-016 Error in SD is: 0 Accumulator 2 data: Error in mean is: 9.25186e-015 Error in SD is: 2.71685e-012 Accumulator 3 data: Error in mean is: 5.82076e-016 Error in SD is: 0.0717315 Accumulator 4 data: Error in mean is: 9.87202e-015 Error in SD is: -1.#IND As you can see the calculated standard deviation gets progressively worse, in the final case, the computed variance is actually -2, which is clearly non-sensical (and hence the NaN when using it to compute the standard deviation) :-( I haven't tried to debug these cases: stepping through the accumulator code is not something I would recommend to anyone frankly (having tried it previously). No doubt other torture tests could be constructed for the mean - exponentially distributed data where you see one or two large values, followed by a large number of very tiny values springs to mind - this is the sort of situation that the Kahan summation algorithm gets employed for. I'm not sure what one should do about this. These certainly illustrate the kinds of trap that the unwary can fall into. It's particularly a problem for the "scientist in a rush" who may not be either a C++ or statistical expert (whether (s)he thinks they are or not!) but needs a library to quickly and reliably calculate some stats. Better documentation would certainly help, but guidance on (or provision of - perhaps by default) better algorithms might be welcome as well. That's all for now, Regards, John.

request to patch libs/serialization/build/Jamfile.v2 for support of msvc-6.5
by Roland Schwarz 01 Feb '07

01 Feb '07

I tried to port parts of the libs/serialization/build/serialization.jam to bbv2 for better support of the msvc-6.5 compiler. I am currently running a regression which seems to have far lower failing tests. To build with this compiler it is necessary to check out the SPIRIT_RC_1_6_2 branch to a directory first. In the environmet or better in site-config the statement path-constant SPIRIT_RC_1_6_2 : "H:/Projects/boost/SPIRIT_RC_1_6_2" ; has to be added. Of course the shown path needs to be replaced with your checkout path. (Forgetting to do this will emit an error message with instructions.) Unfortunately this approach does not help with borland-8.5.2 because it still does not compile with SPIRIT_RC_1_6_2 in place. Any help on this highly appreciated!
