utf8_codecvt_facet::do_length() signature
by Maurizio Vitale 16 Nov '07

16 Nov '07

w.r.t boost in HEAD and GCC 4.2.1: boost/details/utf8_codecvt_facet.hpp specifies do_length as do_length(const mbstate_t&, const char*, const char*, size_t) const the first const comes from the expansion of the macro BOOST_CODECVT_DO_LENGTH_CONST, which is defined in the same file as: #if !defined(__MSL_CPP__) && !defined(__LIBCOMO__) #define BOOST_CODECVT_DO_LENGTH_CONST const #else #define BOOST_CODECVT_DO_LENGTH_CONST #endif But in GCC 4.2.1 do_length is defined in /usr/include/c++/4.2.1/bits/codecvt.h without the const specifier. This causes a warning. When boost is installed in system include directories this warning is typically masked (unless you use -Wsystem-headers). But people having boost in their own directory (say as a fallback strategy when boost is not found on the system) would see the warning. And if the use -Werror their compilations would stop. I don't know what the standard prescribes for do_length, but at least from the time being GCC should be added to the list of exceptions when defining BOOST_CODECVT_DO_LENGTH_CONST (or if most libraries define the non-const version have that as default and make exceptions for toolchain that have the const specifier. I haven't checked how boost tests are set up, but if they are only run on libraries installed in system directories it might be useful to add tests for when boost is installed locally. This would catch problems like the above. Thanks for the great job on boost and hope this fix can be added to the new release. Best regards, Maurizio

[filesystem] add directory begin() and end()
by v2cechura 16 Nov '07

16 Nov '07

[-- I crosspost this message to Boost Users List by mistake yesterday --] I would like to suggest adding functions (template functions?) that would return "begin" and "end" iterators for given path. I think that it's clearer to see: for_each(directory_begin( dir_path ), directory_end(), do_something()); than: for_each(directory_iterator( dir_path ), directory_iterator(), do_somethig()); The functions directory_begin()/directory_end() would mimic the convenient container.begin()/container.end() functions used in STL. I know that it's merely a decoration but so is std::make_pair. It could just be: template <class Path> inline class basic_directory_iterator<Path> directory_begin(const Path& dp) { return basic_directory_iterator<Path>(dp); } template <class Path> inline class basic_directory_iterator<Path> directory_end() { return basic_directory_iterator<Path>(); } Vaclav Cechura

[thread] TSS Cleanup fixes
by Anthony Williams 16 Nov '07

16 Nov '07

Hi, The attached patch changes the way that TSS cleanup is done. I believe this will fix the problems being experienced with using LoadLibrary, and with the thread_specific_ptr destructor being run before all the TSS data has been cleaned up (e.g. in boost wave). Please could people check that this fixes the problems they are experiencing. If it does, I will commit this to trunk.

[serialization] New Primitive Types
by Andy Tompkins 16 Nov '07

16 Nov '07

Hi, If I create a new class, my_class, am I allowed to mark it as follows: BOOST_CLASS_IMPLEMENTATION ( my_class , boost::serialization::primitive_type ) The comments in level.hpp say that it won't call serialization code, thus I believe (and experience) that I don't need to provide either: template<class Archive> void my_class::serialize(Archive &ar, const unsigned int version) or template<class Archive> void serialize(Archive &ar, my_class &t, const unsigned int version) The comments also say that 'It presumes a member function or template in the archive class that can handle this type.' Does this mean that current archives (text, xml, and binary) are not able to use new primitive types without altering the archive to handle the new primitive? As I try it, both the text and xml archives use stream operators to convert my_class to a string and archive that. The binary archive casts my_class to a void* and outputs sizeof(my_class) bytes to the archive. It this expected behavior? Thanks, Andy.

[rfc] thread-safe monitor objects
by Frank Mori Hess 16 Nov '07

16 Nov '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've written a couple small classes to better support the creation of monitor objects, see: http://www.comedi.org/projects/libpoet/boostbook/doc/boostbook/html/poet/mo… I'd like to know if there's any interest in adding something like this to boost, and also looking for ideas on how to improve my implementation. It works via a monitor_ptr class, which is like a shared_ptr with automatic mutex locking, plus an (optional) monitor_base class that lets classes managed by monitor_ptr do wait/notifies on a condition. I put it in libpoet, but the monitor_ptr and monitor_base stuff really only depends on boost. - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHPIjA5vihyNWuA4URAlXaAJ0YmyV2ZgBTOc1Okn29aHP3Of7R0gCfUrf3 6nVluGNuKFCEy59ukjQcbMY= =u0Sq -----END PGP SIGNATURE-----

[thread] TSS Cleanup on win64
by Anthony Williams 16 Nov '07

16 Nov '07

Please could someone with access to the MSVC compilers on a 64-bit platform replace libs/thread/src/win32/tss_pe.cpp with the attached version and run the test_tss_lib test from the thread library. Currently this test is failing on MSVC 8/win64 due to lack of automatic cleanup of TSS data. Hopefully the attached version of tss_pe.cpp will fix that.

[thread] thread interruption semantics
by Preston A. Elder 16 Nov '07

16 Nov '07

Hey all, I just finally checked out the subversion version of boost (I was still on CVS, oops!). I noticed that the threading library now supports something called 'interruption', which seems to be at the thread level. While I applaud this effort (see a previous post where I created an interruptable_mutex) it has some major deficiencies. First, its presence in the boost::thread class gives the impression the thread can be interrupted at any time. This would mean behavior something akin to a pthread_kill() call in POSIX - which it does not. Second, the only thing it can interrupt in its current implementation is a condition - but unfortunately it does this by doing a broadcast to that condition which means two things. 1) ALL threads waiting on that condition wake up - which is not desired. 2) All threads waiting on that condition try to acquire the same mutex, meaning the thread you interrupted may have to wait for n other threads to acquire the mutex, check to see if they should have woken up, possibly do something, and then go back into the condition before the interrupted thread finally gets the lock, and the exception is thrown. And all this is assuming the coder wrote his code correctly to check to see if he got a condition notification correctly (ie. doesn't assume he can do something if he gets notified, and tries to do something erroneously). Third, interruption should also apply to locks - which would in part solve the above situation. The problem with this of course is that it is less efficient to use a mutex/condition crafted to work with interruptions at the lock level. If you want to continue to offer interruption (which, by the way, I fully support!) - I believe it should be done one of two ways. 1) Use a signal on POSIX systems and find some equivalent mechanism on other systems. This will then actually mean what the user thinks - thread::interrupt() interrupts the thread, not just breaks out of a condition if it happens to be in one. Or 2) Move interruption to its own series of structures. Like I did, with an interruptable_mutex. The advantage of this is twofold: 1) It can be implemented in a non-platform specific manner, using existing data structures, so you implement the interruptable version once (utilizing boost::mutex and boost::condition) and you don't have to care about the underlying platform. This means it doesn't require any OS specific support. 2) It works exactly as the user thinks. An interruptable_mutex can be interrupted while blocked on something to do with it (meaning when trying to acquire a lock on it, OR when waiting on a condition with it). Once again, I'll post the code to my interruptable_mutex - though of course it is based on the CVS (aka. boost 1.34.1) threading library: http://www.neuromancy.net/fisheye/browse/mantra/trunk/Mantra-I/mantra/utils… It uses an interruptable_pred as the predicate that signals the interrupt should happen. So you create an interruptable_pred that has a reference to an interruptable_mutex, and then lock the predicate or pass the predicate to a condition (I had to specialize the wait() functions in condition to make this work, but it DOES work). This allows you to have a single lock, but then have each thread have its own predicate, or even multiple threads to use the same predicate (so a single interrupt interrupts multiple threads potentially). Once again, I applaud you for including interruptions into boost::threads, but it really should be complete. I am probably going to try and re-write my interruptable_mutex to work with the new threading architecture (I will have to understand it better, and figure out how to replicate the current functionality), but in the mean time, something for you all to think about. PreZ :)

[thread] Shared Mutex views?
by Preston A. Elder 16 Nov '07

16 Nov '07

Is there any plan to implement something like this: http://www.neuromancy.net/fisheye/browse/mantra/trunk/Mantra-I/mantra/ utils/shared_mutex_views.h?r=435 So that a shared mutex can be operated like a normal mutex, including scoped_lock behavior, and you can choose whether that scoped_lock behavior should be to acquire an exclusive, a shared, or an upgrade lock? The idea being: // somewhere else shared_mutex smtx; // Where I need it: shared_mutex_view smv(smtx); shared_mutex_view::scoped_lock sl(smv); // ... // OR: exclusive_mutex_view smv(smtx); exclusive_mutex_view::scoped_lock sl(smv); Right now, shared_mutex only has primitives, and cannot be used with things like scoped_lock (aka. unique_lock). Additionally, it cannot be used as a condition, despite the condition framework. These views would facilitate that, however I'll admit, I've not thought of all the implications of such things. PreZ :)

[Thread] Wave segfaults at application cleanup in thread library
by Hartmut Kaiser 16 Nov '07

16 Nov '07

Hi all, Since a couple of days (2-3 days) the Wave tests started to fail because of a crash during application cleanup in the thread library (msvc-8, gcc3.4.5/Mingw - this problem seems to be constrained to the windows platform). The point of the segfault is here: boost/thread/win32/tss.hpp:+30, void cleanup(T* data) const { if(func) { func(data); // <-- here } else { delete data; } } Where data is a valid pointer, but func points somewhere. No code changes have been done lately in Wave (or in Spirit/Phoenix for that matter, because the tss is used in Spirit code). Any clues what might be the reason? Regards Hartmut
