1.33.0 Release, why not Beta it first?
by Michael Goldshteyn 02 Aug '05

02 Aug '05

I am going to once again raise the issue of putting the releases into Beta, prior to making a final (6-9 month) release. Perhaps we need a policy of the release being in a final Beta built form for some period, say 2-4 weeks, prior to the final release. I think this will allow people who wait for a packaged version to experiment with any newly added features, fixes, etc... and report issues that can be resolved in the final release, but were not made visible by the regression tests. Just my opinion, Mike

[Brian Braatz Writes:] ideas- have the container accept a list of possible index types then use inherit_linearly<> to make those types- (only as pointers) then when the index gets runtime added- you store it in the generated objects Additionally- one could also force the user to make a struct to use as a tag to reference the index (instead of the number) using this "type tag", you can lookup the runtime object(s) which were dynamically added. What I am suggesting is a similar design to what I recently got working on something else (almost ready for sharing with the world). I have yet another plan trip tomorrow (ALL DAY tomorrow). I will code a small sample of what I am suggesting. (code is easier to talk about than concepts sometimes :) ) Joaquín M López Muñoz writes: > If I wasn't clear enough please tell me so and > I'll try to elaborate.

[1.33.0] Partial thaw on branch for fixing the remaining failures
by Doug Gregor 02 Aug '05

02 Aug '05

The RC_1_33_0 branch is partially thawed so that we can fix the remaining failures for release. I've started the regression notifications again, this time on the release branch: when no more failures show up, we release. Library authors: for any failures that you will not fix, mark them as expected failures on the branch. If you believe there is a configuration problem on one of the test machines, write to the list to say what you think is going on and we'll try to get it fixed. The list of issues we need to fix before we can release is here: http://engineering.meta-comm.com/boost-regression/CVS-RC_1_33_0/ developer/issues.html Doug

[1.33.0] 300+ Broken links
by Jonathan Turkanis 01 Aug '05

01 Aug '05

Hi, I ran a shareware HTML link checker on release candidate 1, and found 334 broken links; I'm attaching the report. A few of them appear bogus ("Error: invalid syntax"), and some appear to reflect the temporary unavailability of news.gmane.org, but most appear legitimate. I'll volunteer to fix as many of them as I can, if it's not too late to make it into the relapse. Some I can't fix, because I don't know where they're supposed to point. Here are the affected areas of Boost: Libraries: - compatibility - conversion - crc - date_time - disjoint_sets - filesystem - format - function - graph - hash - iterator - math - minmax - multi_index - numeric/conversion - numeric/interval - numeric/ublas - parameter - preprocessor - property_map - ptr_container - python - random - range - rational - regex - serialization - smart_ptr - spirit - test - threads - timer - tuple - type_traits - utility - variant - wave Tools: - build (v1 + v2) - boostbook Misc: - index.htm - doc/html/index.html - doc/html/who_s_using_boost_.html - doc/html/who_s_using_boost_/open.html - more/discussion_policy.htm - more/mailing_lists.htm - more/test_policy.htm - more/background.html - more/bibliography.html - more/cpp_committee_meetings.html - more/error_handling.html - more/formal_review_schedule.html - more/generic_exception_safety.html - more/generic_programming.html - more/getting_started.html - more/regression.html - more/version_history.html - more/writingdoc/template/definitions.html - people/darin_adler.htm - people/dietmar_kuehl.htm - people/jonathan_turkanis.htm - people/mark_rodgers.htm - people/people.htm - people/ralf_w_grosse_kunstleve.htm - people/vesa_karvonen.htm Jonathan
