Re: [Pharo-dev] untypeable key combination

by Nicolai Hess

We now use a new class for the space-key as key combination. fixed and included in 50045 (https://pharo.fogbugz.com/default.asp?15529) This way we don't end up with hundreds of obsolete class instances. But the problem with circular references still exist. 15535 <https://pharo.fogbugz.com/default.asp?15535> break circular reference for keymappings I could need some help here, any idea how to work with the key mapping registration without holding (or how to release) strong references? thanks in advance nicolai 2015-02-20 9:26 GMT+01:00 Marcus Denker <marcus.denker(a)inria.fr>: > > > On 19 Feb 2015, at 10:19, Nicolai Hess <nicolaihess(a)web.de> wrote: > > > > Fogbugz issue 14936 > > and slice in inbox > > > > After loading this slice, there are still many references to the (now) > obsolete class KMUntypeableSingleKeyCombination. > > I tried to remove these references with the following code : > > > > NECPreferences popupShowWithShortcut: nil. > > KMSingleKeyCombination reset. > > KMSpecialCharSingleKeyCombination reset. > > KMRepository reset. > > > > > > But they arent removed. > > > > Anyone knows how to re-init all users of > KMUntypeableSingleKeyCombination ? > > > > > > Very strangeâ¦ using âexplore pointersâ with the old inspector, it shows > lots of instancesâ¦ I sadly have no > time to now look deeper, but the pointer explorer should be a way to find > who holds onto themâ¦ > > Marcus > > > >

OLEDB versus ODBC

by Ben Coman

I hust bumped into some old news (2011) I hadn't heard before that I thought might be of interest to those working on database drivers for Pharo, to perhaps not spend any time on OLEDB. "Microsoft announced it will focus on supporting the Open Database Connectivity (ODBC) approach for SQL Server application programming interfaces (APIs) in the near future. Microsoft indicated that it will gradually step away from supporting OLE DB." https://redmondmag.com/articles/2011/09/01/microsoft-shifting-to-open-datab… cheers -ben
