Hello,
I am pleased to announce the release of GNU dbm version 1.20.
GNU dbm is a library of database functions that use extensible
hashing and work similar to the standard UNIX dbm. These routines
are provided to a programmer needing to create and manipulate a
hashed database.
Here are the compressed sources and a GPG detached signature:
https://ftp.gnu.org/gnu/gdbm/gdbm-1.20.tar.gz
https://ftp.gnu.org/gnu/gdbm/gdbm-1.20.tar.gz.sig
Use a mirror for higher download bandwidth:
https://www.gnu.org/order/ftp.html
Here are the MD5 and SHA1 checksums:
006c19b8b60828fd6916a16f3496bd3c gdbm-1.20.tar.gz
f3200c9c4e5c7de4978f838bbabeaa7c5b857bd7 gdbm-1.20.tar.gz
New in this release:
* New bucket cache
The bucket cache support has been rewritten from scratch. The new
bucket cache code provides for significant speed up of search
operations.
* Change in the mmap prereading strategy
Pre-reading of the memory mapper regions, introduced in version 1.19
can be advantageous only when doing intensive look-ups on a read-only
database. It degrades performance otherwise, especially if doing
multiple inserts. Therefore, prereading is no longer enabled
automatically and a new flag to gdbm_open is provided, which enables
it (GDBM_PREREAD).
Best regards,
Sergey
