I am pleased to announce the release of DataMapper 0.10.0 Release Candidate 1.
For the impatient, here are the command line instructions to install it: Install ------- 1) Add gems.datamapper.org as a gem source: gem sources --add http://gems.datamapper.org 2) Install the dm-core gem: sudo gem install dm-core 3) (OPTIONAL) Install whatever dm-more gems you use, eg: sudo gem install dm-aggregates sudo gem install dm-constraints sudo gem install dm-migrations sudo gem install dm-serializer sudo gem install dm-timestamps sudo gem install dm-validations sudo gem install dm-types 4) (OPTIONAL) Install the database driver, or adapter you plan on using, eg: sudo gem install do_sqlite3 # or do_mysql/do_postgres NOTE: dm* and do* gems should be at version 0.10, while extlib will be at version 0.9.13. NOTE: the DO gems probably need more testing with Windows, which we are doing right now. Ted Han will post a follow-up to this thread with the results of the test. What's New ---------- The largest difference between the new 0.10 series and the new 0.9 series is not so much the API changes, it's the approach we've taken to developing it. Rather than add a ton of features and bloat, we took a step back and decided to address two of the weakest areas in DM: specs and documentation. We began documenting the public and semipublic APIs for each method. (A public method is the part of the API that you'd be using as a DataMapper user, while a semipublic API is more for plugin authors). We documented and specced the *intended* behavior of each method, not necessarily the actual behavior, and began working towards making those specs pass. As the spec coverage grew, we began to refactor some of the DM internals to make things more clear, but we tried not to get carried away with this unless it was necessary to make things work. In some cases, like with relationships/associations, to match the intended behavior we had to rewrite nearly all the code. Even with us taking a conservative approach to rewriting internals, there were 2-3x more commits and changes between the 0.9 and 0.10 series than there were since the beginning of the DataMapper project and 0.9, so this is a large update. We also rewrote the Adapter API to make things easier for adapter authors to make full use of the DataMapper features. In the past many adapters only implemented partial behavior because the backends were limited in what they could provide in terms of matching, sorting and limiting the results. In those cases we're now providing helper methods to fill in any holes in the storage engine capabilities. What's left ----------- While working on the 0.10 series we identified a number of areas of improvement, but to avoid getting distracted we've added them to the wiki: (Feedback welcomed) http://wiki.github.com/datamapper/dm-core/roadmap Many To Many associations are much more stable than in the 0.9 series. One of the main reasons we decided to do this release is that we noticed we started spending more time telling people reporting bugs to "try it with dm-core/next", and more often than not it did fix the problem. Are we done with Many To Many associations? No -- there are still a few known issues with edge cases -- but we're 95% of the way there. We still need to continue documenting more of the public and semipublic using YARD format. Also over the next few months we're going to work on increasing the coverage of the specs even further. What we need ------------ We're now at the point where we need some real-world testing outside of a few dedicated people who have been tracking edge. If you have a spec suite, then please upgrade DataMapper, run your specs and report any issues you encounter. (Fix/ignore the deprecation warnings of course) DataMapper is a pretty difficult project to fully spec due to it's flexibility, and ability to use one of dozens of storage adapters. If you do encounter a use case that we haven't covered, please submit a ticket and we'll work on adding it to our spec suite. Report any issues you find in IRC, on the mailing list, or in the tracker: IRC: #datamapper Mailing List: http://groups.google.com/group/datamapper Bug Tracker: http://datamapper.lighthouseapp.com/projects/20609-datamapper Please search through the existing tickets prior to submitting, but when in doubt please create a ticket. I would rather have to sort through dupes or tickets that turn out to be resolved/invalid than for a valid bug to go unreported. Likewise if you're experiencing any problems with 0.9.x, please try the RC1 and see if it resolves your problem. If it does, and you've created a ticket for it, please add a comment to the ticket so we can close the ticket. -- Dan (dkubb) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "DataMapper" group.
