[test] missing links on doc

06 Mar '08

Hello In the release branch file:///C:/cygwin/home/Vicente/boost/boost_1_35_pre/libs/test/doc/examples/unit_test_example5.html the reference to unit_test_example5.input is invalid. The same is true for unit_test_exampleI.input I in 1..5 The same seams true on trunc. ____________________ Vicente Juan Botet Escriba

[thread] Questions about TSS
by Andrey Semashev 06 Mar '08

06 Mar '08

Hi, I have a couple of questions about thread_specific_ptr in 1.35. 1. I can see that there is an ability to set up a logic of reclaiming resources that thread_specific_ptr points to. Why is it limited (a) only to a pointer to function and (b) can only be set up in thread_specific_ptr's constructor? It might be better to provide interface similar to shared_ptr in this way? BTW, I can see that although the cleanup function is required to receive T* as its argument, it is being passed void* in the run_custom_cleanup_function. Isn't an explicit cast required here? 2. Why thread_specific_ptr isn't copyable? Why can't it share TLS keys (or whatever it uses to find the thread-specific resource) in the dynamically allocated cleanup object? I would expect thread_specific_ptr, being a pointer as its name implies, to be copyable.

[proto] where is proto in svn?
by Phil Endecott 06 Mar '08

06 Mar '08

According to "Installing Proto" at http://boost-sandbox.sourceforge.net/libs/proto/doc/html/boost_proto/users_… " You can get Proto by downloading proto.zip from http://www.boost-consulting.com/vault/index.php?directory=Template%20Metapr… or by accessing Boost's SVN repository on SourceForge.net. Just go to http://svn.boost.org/trac/boost/wiki/BoostSubversion and follow the instructions there for anonymous SVN access. " The instructions linked to at http://svn.boost.org/trac/boost/wiki/BoostSubversion point to svn.boost.org (as I expected), where I can't find proto. So maybe it really does mean SourceForge; I thought that was defunct though. Giving the actual URL for the subversion tree would be really helpful... Oh hang, on I've found a _branch_ called proto at svn.boost.org; is that what I want?... except that it also doesn't seem to have a proto directory! Am I being an idiot? (I did get a bang on the head earlier, maybe it has given me a blind spot between property_tree and ptr_container...) Is everyone else using the zip file? Phil.

call_once, headers and shared libraries
by John Maddock 05 Mar '08

05 Mar '08

This came up in the floating point utilities review without a good answer, but it's a general problem that's in need of one, so let me try again.... Suppose we have some global data that needs to be initialised, the obvious answer is to use boost::call_once to ensure that it gets initialised exactly once. But... what happens if this is used in a header to initialise some static variable inside a template instance, and that template is used in more than one shared library/dll? At least on Windows I'm assuming that each dll gets it's own instance of the template, and we end up with two different versions of the static data with unpleasant results. Other than "don't do that", does anyone have a design or usage pattern that sidesteps this issue? This isn't a hypothetical question either, Spirit is using call once like this inside object_with_id_base<TagT, IdT>::acquire_object_id and perhaps elsewhere as well. It's also a fundamental requirement for custom iostream manipulators to be able to call std::ios_base::xalloc exactly once and store the returned ID for future reference by all subsequent calls, regardless of which shared library or dll they may be in. Incidentally both Boost.Fusion and Boost.Tuples call std::ios_base::xalloc without a call_once guard (so are not thread safe?), and presumably have the multiple-instantiations in different modules problem as well. Looks for a cunning answer yours, John.

[interprocess] Doc bug.
by Rene Rivera 05 Mar '08

05 Mar '08

Ran into something that AFAICT is amiss in the interprocess docs. In various places it says: "If a thread takes ownership of the mutex the mutex must be unlocked by the same mutex." Should that instead say: "If a thread takes ownership of the mutex the mutex must be unlocked by the same thread." Note, the last word. Or is the locking and unlocking at the process level, instead of at the thread level? Meaning should it instead read: "If a process takes ownership of the mutex the mutex must be unlocked by the same process." -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org (msn) - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim,yahoo,skype,efnet,gmail
