No assumptions are made about semantics, only that the required operations exist for ValueType. What is the default value type in Quan? I'm guessing it has something to do with a united value or some other manipulation of value semantics within Quan? Also be careful of literal values and promotions. 3 is an integer, 3.0 is a double, 3L is a long, 3LL is a long long, etc. Eric.

But on systems which support WCONTINUED boost.process shouild support it.

[RC_1_34_0] MSVC 8.0 link looking for lib*
by Dean Michael Berris 18 Aug '06

18 Aug '06

Hi Everyone, I've recently updated my local copy of RC_1_34_0 (as in a couple days ago), and the build/install problem recurred: when I do `bjam --v2 install' the headers (boost/*.hpp) weren't copied to the destination directory (c:\install by default, and even in --prefix=...) and the library files don't have the `lib' prefix (boost_date_time-vc80-1_34.lib) save for libboost_prg_exec_monitor and libboost_unit_test_framework. This used to be fixed, but now it seems like the build scripts were reverted or something else happened between then and now. Hope this helps, and keep up the great work guys! -- Dean Michael C.

[Asio] How do i code a resource clean server shutdown?
by Rod Morison 18 Aug '06

18 Aug '06

I'm studying the async daytime server example, Daytime.3 (0.3.7 flavor): http://asio.sourceforge.net/boost_asio_0_3_7/libs/asio/doc/tutorial/tutdayt… (I'm doing an Asio proof/concept for an app that has to dynamically change it's service ports.) I'm trying to think through how to perform a clean shutdown in this example. There could be a number of pending async_write()'s, each with their own socket and uncalled handler. There is probably also a socket waiting on the async_accept() with an an uncalled handler. Questions: - With the work pending, io_service will need to call it's interrupt() function (from another thread) to stop processing, correct? - If io_service is destroyed, what happens to the otherwise pending work, i.e., the async_write's and async_accepts that it controls? What about the socket resources? - I can close the tcp::acceptor in tcp_server, but what about the socket that's listening on it? - If Asio doesn't release system handles, e.g., sockets, how do I get at the resources to clean up? - Is there an example of a resource clean shutdown? I skimmed the example apps and didn't see one first pass. Thanks, Rod - If the io_service is destroyed, what Is there a way to do this with the io_service? In a watchdog thread... -call io_service.interrupt() to stop processing -tell the tcp_server to The io_service.run() won't exit until all services and handlers are finished. Let me take a stab at a shutdown design and perhaps Asio vets would be willing to tear it apart/fix it? This assumes the Daytime.3 server code at http://asio.sourceforge.net/boost_asio_0_3_7/libs/asio/doc/tutorial/tutdayt… (I noticed the 0.3.6 example is somewhat different.) in tcp_server ------------- - add a cleanup() method that calls acceptor_.close() in main() --------- - add a watchdog thread that will shutdown the server's io_service - if shutdown time then How do I notify handlers io_service.dispatch() or io_service.post() to wake up handlers

That needs to be fixed. Thanks for pointing it out. For now you could use: ip::tcp::resolver::query query("foobar.com", "0"); instead to get the same effect. Cheers, Chris

[asio][tr2] rough draft of TR2 proposal
by Christopher Kohlhoff 17 Aug '06

17 Aug '06

Hello all, I have just uploaded a rough early draft of a TR2 proposal based on asio: <http://sourceforge.net/project/showfiles.php?group_id=122478&package_id=199…> The contents of the proposal are based on the system error_code version I uploaded to the vault a few weeks back. There are some minor differences however, and I plan to update the code and upload a new version that matches in the near future. Feedback is welcome. Please keep in mind that there's still a lot left to write. In particular, the design discussion is really just a quick aggregation of some existing docs plus some points that I want to expand further. I'd be interested to hear what else people would like to see covered. I know there are opinions on things like how stuff should be arranged into header files, so let's hear them :) Also, does anyone know of (or would like to invent) some standardese for discussing threading issues like thread safety and memory visibility? Cheers, Chris

TR1 Mathematical Special Functions
by Joel Eidsath 17 Aug '06

17 Aug '06

Is there anyone working on adding a boost-license compliant implementation of these to boost.TR1? I'm looking at the possibility of doing some work on this as part of a directed study. What is the status of the TR1 math special functions in regards to standardization, etc.? As I recall, there were problems in the TR1 specification as far as error boundaries go. Joel Eidsath
