Maybe the developpers list can help? I try to have the POSIX behaviour under cygwin but get only the windows behaviour even if I compile the library and program with -DBOOST_POSIX_API. What should I do? Regards F.

thread abort exception - continued
by Ninel Evol 09 Jul '07

Sorry, I'm a little late - here goes: Anthony Williams wrote: > The current C++0x thread library proposal (http://www.open- > std.org/jtc1/sc22/wg21/docs/papers/2007/n2320.html) includes > request_cancellation(), which requests a thread cancel at > the next call to cancellation_point() or one of the standard > cancellation points (such as waiting on a condition > variable). I intend to add this facility to Boost.thread > once the move to subversion is complete. Yes - and it's useful. I would like to see both possibili- ties! The cancellation by "polling" is most useful when writing server- or lib-code. A GUI friendly approach has to be different however. If you have to poll anyway - why go through all the thread trouble anyhow - just poll the GUI event loop instead. Creating worker threads is usually done for convenience. Polling is inconvenient. I read the proposal. One thing that stroke me was the list of recommended cancellation points. They all somehow imply that the thread is already "on hold" (if not polling). Let's look at real life examples: 1. You have an editor or whatever application; the user has selected a file that is to be read in. For convenience, the reading takes place in a background thread. The user has the possibility to cancel the operation. Suppose the file is large and being read over a dead slow NFS connection. So (s)he chooses to cancel. Where is you cancellation point in there? Is the application supposed to get stuck (as many do)? 2. The classical worker thread pattern: You have a really tight loop computing something. You just don't want to poll in there as it hurts. The com- pare operation for checking out of the loop every once in a while already costs too much. What do you do? Currently only "dirty killing" is what I could think of and that usually means that you have to do the cleanup in the main thread (not object-oriented). Those patterns can be found in many (if not the majority) of GUI applications. Sure, you can write around it (see Qt) - but that's rather ugly coding... > This is very messy --- it's asynchronous, so will break all > sorts of stuff. POSIX asynchronous thread cancellation has > successfully demonstrated that it's a bad idea, except for > very specific cases. Posix' threads came late - too late. And as usual they didn't really go for a "pragmatic approach". The old saying: "Posix is better than nothing". I agree that it's a bit messy behind the scenes. However, you can have it the easy way. If you put the thread to sleep first - your patient is in a coma; operating on it is not so tricky then. That was only a bare example, you can of course synchronize it (and you might want to do that in many cases;o). Again, let's take a look at an example: A trickier one - cancellation while retaining data: For example the application has computed for hours and you want to abort the operation and let it finish tomorrow 'coz you need to phone ant Hermine and you only have one line... Silly code example: // either declared in the object or on the heap: map< BigUInt, answer_type > *war_dial; // then in the thread you have to put those // critical accesses within a "critical section": noAbortBegin(); war_dial[ number ] = answer; noAbortEnd(); // or for the forgetful as an object: { noAbort na; war_dial[ number ] = answer; } Behind the scenes this basically increments an atomic variable (check and set). So if you have a cancellation request from another thread (say the main thread), the worker thread is put to sleep. Then the no-abort variable is checked, if not zero a flag is set to indicate to the thread to throw an abort-request itself the next time it ends a "critical section" and the counter is zero (nesting). If the no-abort is unchecked (count of zero) you can fix the instruction pointer to let the thread throw an abort-request when it wakes up. Then you wake the sleeping thread and either wait for it to die, wait with a timeout - or (in case it's all on the heap) simply not care anymore. For the latter you have to make sure not to leave any children running while the parents go dead of course... Very much like C++ exceptions this is not that efficient. It's meant for exceptions - and only exceptions. "Abort requested by user" is one of those (and a very common one too). So I would still like to see both approaches implemented (they complement one another). The possibility to cause an exception within a thread no matter what operation it's doing is very powerful. Asking a programmer to protect critical accesses on persistent data/objects with "critical sections" if using that feature is not too much (and incrementing a variable is rather cheap as well). Hope I don't seem to stubborn about this, but I really think that once it would be there C++/C-0x programmers wouldn't want to miss such a feature anymore. --- about wx: Scott McMurray wrote: > > I read that some folks thought about the wxWidgets and the > > Boost (C-0x) team joining forces. > > I think that would be a marvelous idea! > > I think they'd come to blows, given how reluctant wx seems > to be to use any feature added to C++ in the past 17 years > or so :| > > I don't think that's an ezaggeration, either.

Hahaha, yes - arrays, maps and the like as preprocessor macros... also when it comes to posting bug reports it seems very much like someone there is "running a camp"! X-O It is supposed to be about "backward compatibility" with some compilers from the Jurassic period. However, it looks as if "they" intent to start over with version 3. C-0x is going to end up in the same swamp as C++ without a useable GUI support. Sure, you can have second party libraries. But then you also need support for the second party libs (like GUI builders, usually not integrated) and the swamp sets in deep when debugging non-native objects. "Do it by hand Luke"... Like this, C-0x won't stand a chance against free all-in-one Java or C# (reads: "C crooked") alternatives (not that I would use them - coming from the Assembler countries). Despite the reasonable disbelieves I think that there should be a debate with the wx folks. The problem with C-0x seems to be a lack of resources for something as complex as a proper GUI support. With the wx team maybe willing to start all over (they certainly didn't do a bad job!) joining forces could bring C-0x to new highs. It's worth a try, someone cast the first stone PLEASE! :-) > ...

read_write_mutex
by luca regini 09 Jul '07

09 Jul '07

Hi i am working toghether with Andrey Semashev on the implementation of the new boost logging library. This library depends on the boost read_write_mutex that is abandoned on the current version of the library ( 1.34 ). I would like to know if someone is actively developing it otherwise i can take care of developing the windows version. Greets, Luca

extern placeholders and MSVC 8
by Dean Michael Berris 09 Jul '07

09 Jul '07

Hi Everyone, I've encountered a problem with MSVC which I have no idea how to go around with regards to using extern placeholders for template method type deductions. Let me give an example: template <class T> struct some_type { }; struct a_type { } ; extern a_type placeholder ; template <class T> some_type<T> method(T) { return some_type<T>(); }; // ... { method(placeholder); } The code works (compiles fine) in GCC -- it doesn't bother looking for the placeholder during link time. However MSVC 8 throws a fit and doesn't want to link the executable because it keeps looking for the implementation of placeholder -- where the code obviously doesn't require linking to it in any way, except for the purposes of type deduction in the template method. Am I encountering an MSVC bug? Is there a better way of going about this? Insights would be most appreciated. Thanks in advance! -- Dean Michael C.

Some problems about singleton_pool
by Wei FENG 09 Jul '07

09 Jul '07

When using the "singleton_pool" to allocate the new space, I found there is a limitation in this pool. If I want to allocate 16KB memory space,I can do it by call 65503 times( about 1GB space has been used ). Then, I established another singleton_pool object to allocate 1KB space ,this time I succeed 524255 times( about 500MB memory space). I want to know whether there is a limitation in that? thx. ps : the sample codes: typedef boost::singleton_pool<PieceMemoryPoolTag, UDP_BIG_BUFFER_SIZE+1> BigPool; void* BigMemPool::malloc(void) { void *pbuf = BigPool::malloc(); assert(pbuf); if (pbuf != NULL) { memset(pbuf, 0, UDP_BIG_BUFFER_SIZE+1); bigmalloctimes++; char str[128]; sprintf_s(str, "BigMemPool::malloc %lu", bigmalloctimes); } return pbuf; }

[IBD] Request for Comment, Objectives
by Matias Capeletto 09 Jul '07

09 Jul '07

Hello Boost, The Improving Boost Docs project is starting to have real man power. There are more than twelve developers right now working on different parts of it, and we are actively trying to get more people involved. Since we want to build a long term subcommunity which main purpose is to continuously improve the quality of Boost documentation, we would like that our main directives be aligned with the Boost community as a whole. Anticipating some recurring critics we have seen during the last two weeks we would like to include a little FAQ before discussing our objectives. A) Why do we need IBD? -------------------------------------------------------------------- We believe that documentation is a first class citizen in a project, on par with the code. An incredible library is useless with out good docs. Although Boost has one of the greatest documentation available in Open Source projects, we think that it can be improved. For example, a consistent look and feel through Boost libraries will help users to understand that Boost is not simple a collection of quality pieces, but an amazing always evolving maze that must be seen as whole. IBD main purpose is to be another quality reassurance mechanism, trying that Boost Docs be in the better shape possible for each release. B) IBD is a waste of resources, that will be better expended on new libraries and bug fixes. -------------------------------------------------------------------- This is an interesting critic that has pop up in a few threads. We encourage you to check: http://svn.boost.org/trac/boost/wiki/ImprovingBoostDocs#People IBD is offering a place where people that is not a C++ guru (yet) has the opportunity to collaborate with the Boost community. Working with Boost docs will inevitably make us better C++ programmers, and augment the possibilities to become a Boost author or help with patches. We are not wasting Boost resources, we are getting more hands to make Boost a better place. C) IBD new style and resources have a less sober aspect than other Boost resources, lowering the quality of Boost as a whole. -------------------------------------------------------------------- We like to "enjoy quality". Our idea is that having fun and produce quality products are orthogonal process, and since we will invest a lot of our time at IBD we prefer to enjoy or work. We go one step further with this and think that a happy developer produces better quality products. We think that this discussion is very important for the health of our project. Your feedback will be really appreciated. King regards The IBD crowd --------------------------------------------------------------------------- Here are the project objectives reproduced in the thread to comfortably discuss each of them. IBD objectives http://svn.boost.org/trac/boost/wiki/ImprovingBoostDocs#Objectives * Build up a long term community of people that cares and constantly improve boost documentation and tools. * Achieve an unified look and feel between docs and Boost resources, integrating them as much as possible. * Quality documentation - Provide correct, current and readable documentation for the Boost C++ libraries, tools, environment and organization. - Generate Glue docs that sees boost as one tied entity, providing real-world examples, best practices for common tasks and tutorials about how to combine Boost libraries together to build high-quality C++ applications. - Provide a publicly available, vendor-neutral reference manual for the Standard C++ library, STL concepts, data types and algorithms as part of the Boost library documentation. - Make it easier for users to navigate through the enormous amount of boost documentation. - Use latest version of standards and support old browsers. - Include nice looking logos and diagrams. Although Boost libraries are so great that they do not need any marketting at all, lets face it: people are attracted like flies to catchy names and fancy pictures. * Documentation tools and support - Improve the docs tool chain, simplifying and integrating it lowering the barrier for people willing to help us. - Develop tools to automate common task, and to make life easier to boost authors. Docs writers should concentrate on generating content and not on figthing with tools. - Work to make doc tools boost-agnostic. We believe that they are useful beyond the boost community, and would welcome anyone who wishes to use, extend or support them. * Generate formal documents about C++ documentation best practices. * Offer our help to libraries authors. This include translations, proof-reading, proposing examples and tutorials for their libraries and helping them with the docs tool chain. * Offer a place where not C++ experts can help the Boost community. In general the tasks we do here does not involve template metaprogramming or others complex C++ machinery. Dessigners, artists, teachers, web experts, Python programmers and Boost users are very welcome along our lines. * Write docs, include rationales, use our own tools. If we want to improve boost docs, we should start by showcasing best practices in this project. * Enjoy our work. If we are not having fun while improving boost docs something has gone terribly wrong.

[Proto] Access to member in proto expression tree
by dan marsden 08 Jul '07

08 Jul '07

Hi Does proto support member access in its tree generation in any way. I'm looking at a few of the phoenix statement forms, particularly: if_(pred)[statements].else_[statements] and try_[statements].catch_<exception_type>()[statements].catch_call[statements] I need to specify member access to else_ and catch_<exception_type> etc. Is this something I'll have to hand roll, or does proto have some extension mechanism I've missed that will let me add these to the expression tree generation process? As phoenix expressions have operator(), I'm already using an expression wrapper around all my proto expressions, so I presume that is where I would add any special member support?

shared_ptr ticket #398, "Support for embedded VC++ 4.0"
by Peter Dimov 08 Jul '07

08 Jul '07

#398, "Support for embedded VC++ 4.0", http://svn.boost.org/trac/boost/ticket/398 complains that shared_ptr doesn't compile under eVC++ 4.0 because "'type_info' is not a member of 'std'". Can someone who uses or has access to eVC++ 4.0 look at it? Is the ticket still relevant? Can shared_ptr.hpp be made to compile on this platform?
