Changeset: b90f4b84235c for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB?cmd=changeset;node=b90f4b84235c
Modified Files:
clients/Tests/MAL-signatures.stable.out
clients/Tests/MAL-signatures.stable.out.int128
monetdb5/modules/kernel/batstr.c
Branch: Oct2020
Log Message:
Implemented bulk implementations of suffix,prefix and repeat string functions.
Later I will clean the rest.
We have to review who implemented the batstr module in the past. Doing malloc
and free for every row???
