[iostreams] #2406: implementation in header causes link errors
by Vladimir Prus 03 Jun '09

03 Jun '09

Looking at Trac, I've run into the bug above, which seems both fairly severe and easy to fix, so I took the liberty to commit a patch: https://svn.boost.org/trac/boost/changeset/53427 I've tested it on Linux. Can somebody give it a try on Windows? While I've added necessary BOOST_IOSTREAMS_DECL, I might have missed something. Thanks, Volodya

[parameter] Testing for existence of a parameter, building ArgumentPacks, more lazy return types
by Jeremiah Willcock 03 Jun '09

03 Jun '09

I have a few questions about the parameter library. Please note that I am using argument packs directly, since I am creating them from another data structure. 1. Is there a way to build Boost.Parameter ArgumentPacks from a program? I am currently using many internal data structures of Boost.Parameter (empty_arg_list and such). Is there another interface to use? 2. Is there a way to tell at compile-time whether a particular parameter exists in an ArgumentPack? I currently have a metafunction that uses a special default type and tests for that; is there a more "official" way? 3. I have a case where the default type for a named parameter cannot be instantiated in some cases where that parameter is given explicitly. The operator||() lazy defaults don't seem to work for that because they get the result_type member from my default right away, even if it won't be used. I currently have a hack to work around this using my parameter_exists test and some metaprogramming. The reason I am working on this low of a level is that I am playing with converting Boost.Graph named parameter structures into ArgumentPacks to have access to Boost.Parameter's nicer capabilities and syntax. I thus need to build all of the argument data structures and such within another function and then access them later. Thank you for your help. -- Jeremiah Willcock

[Modularization] A new approach to header modularization
by Beman Dawes 03 Jun '09

03 Jun '09

I've started to put together a wiki page based on our ongoing Header Modularization discussions. See http://svn.boost.org/trac/boost/wiki/HeaderModularization I listed eight approaches to meeting the Goals/Objectives/Needs/Wants, and was about to identify the weaknesses of each approach when I hit on approach nine: Move (permanently) each library's root/libs/libname contents into root/boost/libname for the library. In other words, instead of moving the boost/... tree headers to the libs/... tree, merge the libs/... tree into the boost/... tree. For example, Boost.Filesystem is currently organized like this: root/ boost/ filesystem.hpp filesystem/ config.hpp convenience.hpp exception.hpp fstream.hpp operations.hpp path.hpp libs/ filesystem/ build/ ... CMakeLists.txt doc/ ... example/ ... index.html ... module.cmake src/ ... test/ ... After the reorganization, filesystem would be organized like this: root/ boost/ filesystem.hpp filesystem/ config.hpp convenience.hpp exception.hpp fstream.hpp operations.hpp path.hpp build/ ... CMakeLists.txt doc/ ... example/ ... index.html ... module.cmake src/ ... test/ ... In theory, the root/libs/... tree isn't needed anymore. In practice we might want to keep a root/libs/libname/index.html entry for each library so docs links don't break. Apologies if someone already suggested this approach. It is so simple I can't believe someone didn't already suggest it. Unless I'm missing something, this is the only approach that appears to do fairly well for all of the Goals/Objectives/Needs/Wants, and very well for most of them. It would require some rework of scripts and other setups that depend on the current organization of libs/..., but that seems minor compared to the long-term benefits. Comments? --Beman

Attachments from old bug tracker
by Jeremiah Willcock 03 Jun '09

03 Jun '09

It appears that somebody attached patches to the equivalent of bug 900 (https://svn.boost.org/trac/boost/ticket/900) in the old bug tracker, and these patches were not moved over to the new tracker. Is it possible to get these attachments? -- Jeremiah Willcock

Just curious, was the presentation by Andrei(Iterators must go) was videotaped? and any chance to grab the videotapes(and the ppts) for earlier boostcons?

[Bug Sprint] What to do with "library submissions"?
by Marshall Clow 03 Jun '09

03 Jun '09

I'm not sure they belong in the Trac system; but where do they belong? I guess it depends on what's going to happen to them.... If they're additions to existing libraries, should they be "feature requests"? If they're new libraries, should they go in the sandbox? https://svn.boost.org/trac/boost/ticket/2749 https://svn.boost.org/trac/boost/ticket/2893 -- -- Marshall Marshall Clow Idio Software <mailto:marshall@idio.com> It is by caffeine alone I set my mind in motion. It is by the beans of Java that thoughts acquire speed, the hands acquire shaking, the shaking becomes a warning. It is by caffeine alone I set my mind in motion.

[#1497] Ruling needed on tracker usage
by Beman Dawes 03 Jun '09

03 Jun '09

Dave is pressing to do something about this ticket: > Yes, please! Beman, please read the head of that thread: > http://thread.gmane.org/gmane.comp.lib.boost.devel/167139 > > IMO this is '''exceedingly''' important, and the only reason I'm not doing > it myself is that it seems to be the domain of the release managers. It > will be an especially huge missed opportunity if we don't get this > straightened out before the bug sprint. Oops! That starts today! We'd > better get moving. > > Again, if there's any way I can help, including writing the policy, please > let me know. By the way, I'm not attached to eliminating "to be > determined," if that helps in any way to resolve this. The concern of the thread mentioned was about milestones for 1.35.0. The same concern applies today, although the milestone numbers have changed. > [the milestone list] > shows all the tickets that have been assigned to the 1.35.0 milestone. > Does this list have any meaning? It doesn't for me, and hasn't since we went to a schedule-driven release system a year and a half ago. > In other words, are we actually > intending to address all of these problems for 1.35, and put off other > tickets for 1.35.1 or 1.36.0? > > IMO getting this list sorted out and handling the tickets one-by-one > is the most productive way to get us from here to a successful release > of 1.35.0.

In an organization with paid developers and paid managers, it might be possible to look at the tickets, look at the people and other resources available, assign milestone priorities accordingly, and then use progress on clearing them as a metric to guide release activities. But I'm at a loss for how we could use such milestones for Boost. So any ideas would be appreciated if folks think the milestones do have a place in Boost's process of getting releases out. --Beman

[profile_templates] minor issue + patch
by Jonathan Franklin 03 Jun '09

03 Jun '09

Steven, I was playing around w/ the profile_templates tool on my Ubuntu box (Jaunty Jackelope - 9.04), and wasn't getting any results. After a little investigation, I discovered that the regex that postprocess.cpp uses for the enter_message wasn't matching the warning that my gcc compiler (4.3.3) was spitting out. Turns out that the regex is looking for a single char here: (.*): warning: .int -----------------^ But I'm getting a unicode E28098 (left single quotation mark), which is 3 chars, hence the failure to match. Being somewhat content w/ my terminal settings (and lazy to boot), I just modified the regex to match .+int instead of .int, and it *seems* to work fine. I think I have a sandbox account, and can commit the attached patch if you like the fix. Jon
