[interprocess] non-ASCII characters in headers
by Daniel James 08 May '08

08 May '08

Hi Ion, There are a few non-ASCII characters is the interprocess headers, which cause Boostbook to reject a few of the XML files and miss a few pages from the reference documentation (such as the flat_map documentation). I've fixed them in my doc branch. Is it okay for me to merge it into trunk? http://svn.boost.org/trac/boost/changeset/45154 thanks, Daniel

Why does boost::thread::thread_start_function have catch(...)? (Win32)
by James Talbut 08 May '08

08 May '08

By calling std::terminate in the catch handler we lose the JIT debugger - and thus information about what the exception is that we haven't caught. Without the catch the process is still going to be killed, so what's the benefit of having that? Thanks. Jim P Consider the environment.

I assumed it would be okay because it's spelt that way in other places: http://www.boost.org/users/people/dietmar_kuehl.html http://svn.boost.org/trac/boost/browser/trunk/boost/filesystem/operations.h… I think that the other ways to get this to work would be: to use UTF-8 in the source file, get Doxygen to output UTF-8, or get it to markup the encoding in its output.

[thread] Documentaion and implementation incoherences
by vicente.botet 08 May '08

08 May '08

Hi, Only some comments and questions. * mutex native_handle_type and native_handle() are missing in the doc Should these be defined for timed_mutex, recursive_mutex, ...? * The documentation do not includes a rationale. Could you adapt the rationale from Howard E. Hinnant Mutex, Lock, Condition Variable Rationale http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2406.html#Introduc…, or at least add reference to this document in the rationale?

Hi, Is there any hiden raison explaining the declarations and implementation of thread_group are different for pthread and windons? If not why not to put it in a separate file? Best _____________________ Vicente Juan Botet Escriba

[constrained_value] ignore_policy, overhead?
by Neal Becker 07 May '08

07 May '08

I'm wondering if I can selectively switch off bounds checking without overhead? I added: /** Error policy for constrained that ignores bounds. */ struct ignore { /// The policy invocation operator. /// If @a nv is below the range, assigns @c c.lower_bound() to @a ov. /// If @a nv is above the range, assigns @c c.upper_bound() to @a ov. /// Otherwise fires an assertion. /// @remarks @a V must be @c Assignable from @a L::result_type and @a U::result_type. template <typename V, class L, class U, class C> void operator () (V & ov, const V & nv, const within_bounds < L, value_generator::integral<bool, true>, U, value_generator::integral<bool, true>, C> & c) const { } }; I'm wondering if the this will eliminate all overhead allowing the speed of the underlying ValueType (e.g., int)?

Boost and subdirectories named 'debug'
by Edward Diener 07 May '08

07 May '08

Boost has some subdirectories named 'debug' which contain static files used by some Boost libraries and their dependencies. In some build systems, like MSVC, the 'debug' directory is a directory where intermediate build files, such as object files, are put, and these directories are dynamic in the sense that there contents can always be regenerated from source. A common, if perhaps erroneous, technique of forcing rebuilds in these systems is to wipe out the 'debug' directories. If Boost is in some tree where the 'debug' directories are all being wiped out indiscriminately, then the Boost 'debug' directories get wiped out and source using Boost libraries and/or their dependencies which have 'debug' directories will fail to compile. Yes, I know in the age of IDEs that no one is supposed to build like that anymore, or that it is a very good idea not to put Boost in some tree where the end user decides to arbitrarily wipe out all 'debug' directories in order to force a rebuild, but these things can happen. Because of that this is a gentle suggestion that Boost in the future choose some other name for a subdirectory than 'debug' for those libraries using that name.

[build] symbolic vs hard library links
by Frank Mori Hess 07 May '08

07 May '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 After building boost from svn on linux, I've noticed it produces a mix of symbolic and hard links for the built libraries (output of "ls -l" attached). I'm curious if this was intentional? Have I just configured my source tree in some strange way? - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIIbi+5vihyNWuA4URApvHAJ90L2JBOjvFyPtT1KKRXFS6zsxeigCg0hNH 2FTth+XYWEqSzHFccXRCq/0= =7Uzr -----END PGP SIGNATURE-----

[test] --catch_system_errors questions
by Juergen Hunold 07 May '08

07 May '08

Hi ! I'm using Boost.Test for quite a while and now I wonder if the behaviour of "--catch_system_errors" is correct. I've attached a simple test case which just triggers a simple "assert(false);". Running the testcases with trunk bjam yields one failure and two passing tests. See "test.log" for details. Running the testcases against 1.341. yields three failures with _different_ exit codes. See test_1_34_1.log When looking at the output of trunk "with_catch.test", I see --snip--- with_catch: assert_test.cpp:13: void test_assert::test_method(): Assertion `false' failed. <TestLog><TestSuite name="Master Test Suite"><TestCase name="test_assert"><Message file="assert_test.cpp" line="11">one</Message><Info file="assert_test.cpp" line="12">check true passed</Info><TestingTime>0</TestingTime></TestCase></TestSuite></TestLog><TestResult><TestSuite name="Master Test Suite" result="passed" assertions_passed="1" assertions_failed="0" expected_failures="0" test_cases_passed="1" test_cases_failed="0" test_cases_skipped="0" test_cases_aborted="0"></TestSuite></TestResult> EXIT STATUS: 0 --snap-- So, some observations: Obviously, the UTF succeds in catching the "assert". The resulting message is not in the XML-Log The return code is 0 (Success). A quick look at the new docs prototype at http://www.patmedia.net/~rogeeff/html/utf/usage-recommendations/command-lin… found "If you got fatal exception somewhere within test case, make program generate coredump by adding extra command line argument " This was not easy to spot since the real test cases succeeded with error code 0 and the message was hidden in the log file. I found this because msvc on windows fires up an annoying debug window instead. So it seems this is not working there. So, my questions/suggestions are: Is this a bug ? Or a feature ? And if its a feature, where can I find the rationale ? I think the caught assertions should lead to a non-zero exit code and a failing test suite. And it would be nice if they got properly XML-formatted (but after a quick scan through the source, this seems difficult...) Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold !

[phoenix][spirit] Phoenix 2 already in trunk?
by Dean Michael Berris 07 May '08

07 May '08

I see that there's a new version of Spirit in Boost trunk. I'm just curious though, does this version already have the (much awaited) Phoenix 2 library? If not, is there a good packaging of Phoenix 2 already available? Pointers would be very much appreciated. -- Dean Michael C. Berris Software Engineer, Friendster, Inc.
