Four Questions on boost::shared_ptr
by Jon Wang 04 Feb '02

04 Feb '02

Hi, I've got several questions about the former version of boost::shared_ptr. Would someone please help me? 1. Mr Stroustrup said that there wasn't a need for auto_array, for "a better solution is to use a vector". So, should we use vector or scoped_array/shared_array? 2. In the document, four implementations are said to have been discussed: Direct detached, Indirect detached, Embedded detached and Placement detached. I've tried to describle them (Are I right? See the attached file), but I don't understand the Placement detached. Could someone please tell me what it's like? 3. In the file smart_ptr.hpp, we can see the private function shared_ptr::share. void share(T* rpx, long* rpn) { if (pn != rpn) { ++*rpn; // done before dispose() in case rpn transitively // dependent on *this (bug reported by Ken Johnson) dispose(); px = rpx; pn = rpn; } } // share I'm sorry that I don't understand that reason why ++*rpn should be done before dispose(). Would someone please give me an example? Or is it like this? #include <boost/smart_ptr.hpp> struct A { boost::shared_ptr<A> v; }; int main() { A* pa = new A; boost::shared_ptr<A> ptr(pa); ptr = pa->v; } 4. Why not use policies? I'm afraid that the word "parameterization will discourage users" might not be always true, for we can use default parameters. Jon Wang 2002-01-31

boost python and smart pointers
by Martin Strubel 01 Feb '02

01 Feb '02

Hello, I've lately experimented with Boost.Python and found it pretty useful. Though I've run into one thing which I couldn't figure out by the documentation, I hope someone can give me a hint there: I have a function returning a pointer to an 'owned' structure, i.e. its container takes care of creation and deletion. In Python, I want to wrap this pointer into a direct reference to the struct, i.e. no copying. To guard the access and make sure the object can't be accessed after the deletion, I want to wrap the smart pointer AS a python object. for example, a C++ function returning an 'owned' face from a mesh: FaceSmartPtr Mesh::addFace() { .. } should be wrapped for access in Python like: f = mesh.addFace() with subsequent calls for face manipulation like: f.addVertex((0.0, 0.0, 0.0)) where this should again call something like if (f_sptr.isValid()) f_sptr->addVertex(...); else throw_pyException_ptrInvalid(); Does Boost support this automatically ? Or do I have to wrap all these functions myself ?

I've been using the ACE_Malloc framework from ACE (http://cs.wustl.edu/~schmidt/ACE.html) to solve a similar problem (sharing statics between DLL's). It takes a little while to figure out because the documentation is a little slim, but once you do it pays off pretty quickly. Doxygen documentation for ACE_Malloc is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Malloc__T.html and the shared_mem memory pool is at: http://doc.ece.uci.edu/Doxygen/Current/html/ace/classACE__Shared__Memory__Po ol.html I ended up not having to write an STL allocator using ACE_Malloc, but I don't think it would be too difficult.

I have 47 more files checked into source control that everybody else has to download (and have the tool check every time they refresh) so that I can parse a command line.

Evidently reviewers thought 20 was reasonable, and I assume that some major problems are solved by the 47 headers that weren't by 20.

object_pool, O(N) destroy?
by kevin_godden＠agilent.com 29 Jan '02

29 Jan '02

Hi, I am considering using boost::object_pool for fast allocation and deallocation of likkle container/token objects. I need to make this as fast as possible, to this end I wonder why object_pool seems to use boost::pool::ordered_free() (O(N)) rather than the faster free() (O(1))? There must be a reason, but I can't seem to find it in the Lib's documentation. I would be interested in hearing if peoples experiences/comments on using object_pool. Thanks for reading! Kevin\

I agree, it does sound like a job for a Policy whatsit. If I get a chance I could try a few things and see if anything works out and let you know.

Dependencies for tokenizer?
by Anthony Kolarik 29 Jan '02

In order to use the tokenizer classes I end up requiring 47 files, which seems a little steep for my purposes. All I really need is to tokenize strings based on a couple of single char delimiters. Kind of a C++ step above strtok() was what I had in mind. Any ideas about how to get this functionality w/o all the headers? Thanks, -- Tony K.

Thanks for the Info Steve, In this case, I am less interested in the pool's destructor as I _should_ have a 1 to 1 on malloc()ing and destroying the individual objects (if all goes well...). The pool will only be destroyed once during the lifetime of the application so I could probably suffer a O(N^2) pool destructor. I will try what you recommend in your postscript. Thanks again..

The object_pool keeps its free list ordered because of the requirements of its destructor. Its destructor steps through the free list, calling the destructor for any objects that weren't freed. The current algorithm is O(N) because the free list is ordered; if it wasn't ordered, it would be O(N^2). I'll document this in the code. -Steve P.S. An object_pool without the destructor behaviour may be what you want. Boost.Pool doesn't provide one, but you could just cut & paste the object_pool, remove the destructor, and change ordered_malloc/ordered_free to the regular malloc/free (you also won't need nextof).

1_26_0: regex/thread on W32 build via jam?
by Bruno.Voigt＠ic3s.de 28 Jan '02

28 Jan '02

Hi! For my statically linked application (w32/sol8/linux) I was up to now using only the boost regex library. I build the regex lib the oldstyle way going to the build path and calling nmake -f vc7.mak, etc. In the project settings I included the regex/build/vc7 path as an additional lib search path. The buld step works as expected this way. boost::thread does provide only the newstyle jam build way. So I downloaded the boost::winbuild stuff and tried to build the whole boost via jam -sBOOST_ROOT=. -sTOOLS=msvc. It shows some errors for some pytho stuff but builds the regex and thread lib part. So I get for example a path boost_1_26_0\libs\regex\build\bin\libboost_regex.lib\msvc\release\runtime-link-dynamic with a libboost_regex.lib But how do I have to change my project settings for a static executable? I just changed the the lib search path to this new monster path and it does not work The linker is missing the vc7-re300dm.lib then. And how to link the boost thread stuff? Is it supported for statically linked apps at all? Any suggestions on how to make use of the jam build stuff in the right way ae really appreciated.

Suggestion -- Boost Building
by Duane Murphy 26 Jan '02

26 Jan '02

It seems a lot of questions come up on the list about "building" the boost libraries. I wonder how many of these people realize that most of the functionality of the Boost "libraries" is completely encapsulated in the header files? There are significant portions like regex and the graph library (?) that do require compiling, but much of it does not. Is there anything that can be done to make it more clear that compiling is often not necessary? I'm just trying to relieve some stress from people who may very well not require compiling. And I have compassion for those that do and are having trouble. I'm not sure exactly what can be done, but it might be worth some thought. ...Duane

I wonder if someone can help me get up and running with Boost using VC7. I've tried to follow the Boost Build documentation, and am running into problems. A description of different things I've tried is below. Thanks in advance for any help anyone can provide! So far I've downloaded the Windows version of Boost.Build, and have run boost-build.exe (I couldn't tell if it did anything.) I added the boost-build directory to my PATH by hand, along with the VC7/bin directory. I also remember some discussion about how jam couldn't handle VC's default install dir (which is, for the purposes of this discussion, where mine is) because it has spaces in it, so I've used SUBST to define Z: as my VS.NET path. When I run jam from the boost_1_26_0 dir, using: jam -sBOOST_ROOT=. -sTOOLS="msvc" I get errors that look like: msvc-C++-action libs\regex\build\bin\libboost_regex.lib\msvc\debug\runtime-link- dynamic\c_regex_traits.obj c_regex_traits.cpp c1xx : fatal error C1108: unable to find DLL: 'mspdb70.dll' Z:\vc7\bin\cl /Zm400 -nologo -GX -c -I"libs\regex\build" -Fo"libs\reg ex\build\bin\libboost_regex.lib\MSVC\debug\c_regex_traits.obj" -Tp"libs\regex\b uild\../src\c_regex_traits.cpp" ...failed msvc-C++-action libs\regex\build\bin\libboost_regex.lib\MSVC\debug\c_regex_traits.obj ... msvc-C++-action libs\regex\build\bin\libboost_regex.lib\MSVC\debug\c_regex_traits_common.obj c_regex_traits_common.cpp c1xx : fatal error C1108: unable to find DLL: 'mspdb70.dll' So I added VC7's common7/IDE/ directory to my path, because that's where mspdb70.dll lives, but it didn't resolve the issue. Delving deeper into the docs, I found the suggestion that I do: set TOOLS=msvc jam instead of what the top level docs say, but then I get a message that I didn't set the toolset, and I should use: set VISUALC=<path> set JAM_TOOLSET=VISUALC jam When I do that, I get: Compiler is Microsoft Visual C++ warning: unknown rule project-root warning: unknown rule subinclude warning: unknown rule subinclude warning: unknown rule subinclude warning: unknown rule subinclude ...found 7 targets...
