KD 12:13 PM Wt Open discussion: RE: Postgresql query runs fast, but then becomes slow
Hey Bruce,
Sounds plausible that indeed the long connection times cause issues with prepared statement planning being held. I think reducing the connection lifetime is not such a bad solution --- the pool allows to avoid opening/closing...

KD 03:16 PM Wt Bug #7396: WTreeView not working when hidden during construction
Roel,
Seems reasonable to me if the same thing didn't work in Wt 3 neither? Otherwise I would be curious how Wt3 got to react to resize?

KD 10:31 AM Wt Support #7373: SEH Exception on Wt:DBO rollback

KD 12:17 PM Wt Help: RE: Using sql_value_traits with unsigned integers (uint64_t, uint32_t etc)
Most databases do not support unsigned integer types (and the standard doesn't specify them), asfaik. The design of the Wt::Dbo is to model the data that can be stored in the database using appropriate types in C so that a one-on-one rel... Koen Deforche

KD 12:02 PM Wt Help: RE: Dbo does not persist changes to fields, only collections
Hey,
Wt::Dbo only takes a call to 'modify()' as an indication that you are modifying the object. But it will flush dirty objects whenever a query needs to be done (to make sure dirty changes are consistent with the result of the query)....

KD 08:19 PM Wt Open discussion: RE: Wt::Dbo::Transaction best practices
Hey,
The design is so that in a function, of which you don't want to assume how and when it will be called, and if that function requires a transaction, it should use one. At least that makes the function work in all situations. If the ...
