Hello FPC-Pascal, I wish to fix this bug http://bugs.freepascal.org/view.php?id=15460 but I had found serious problems to understand how data is structured in the TBufIndex and descendant classes, specially the TDoubleLinkedBufIndex.
Can somebody help me ? From TBufDataset.BuildIndex I think that: PBufRecLinkItem.Next points to next record. PBufRecLinkItem.Prior points to previous record. Maybe PBufRecLinkItem points to the dataset item data ? Which is supossed to be pointed by: (AIndex as TDoubleLinkedBufIndex).FFirstRecBuf (AIndex as TDoubleLinkedBufIndex).FLastRecBuf The first and last item in the dataset ? Also which is the meaning of this line: (AIndex as TDoubleLinkedBufIndex).FLastRecBuf[(AIndex as TDoubleLinkedBufIndex).IndNr].next:=(AIndex as TDoubleLinkedBufIndex).FFirstRecBuf; I'm completly lost in this piece of code, and I really need it as my SQL fetches could take around 1 minute and reorder data is a must. I know I can reissue the query with a different order but this will take around 20 seconds again while doing it in local memory is a breeze. PS: To check changes in FPC I'm launching a complete build (without clean) but this process will take 2 minutes anyway. Is there a faster way to correctly build only the affected package (in this case fcl-db) ? -- Best regards, JoshyFun _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
