gdbm-1.23 released [stable]

Hello,

We are pleased to announce the release of GNU dbm 1.23.  See below
for a complete list of changes.

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.  For detailed information, visit
<https://www.gnu.org/software/gdbm>.

Here are the compressed sources and a GPG detached signature[*]:

Here are the SHA1 and SHA256 checksums:

dLEIHSH/8TrkvXwW5dblBKTCb3zeHcoNljpIQXS7ys0  gdbm-1.23.tar.gz

The SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.

Noteworthy changes in this release:

* Bucket cache rewritten using a hash table

Change suggested by Terence Kelly.

* Speed up flushing the changed buckets on disk

* New option codes for gdbm_setopt

** GDBM_GETDBFORMAT

Return the database format.

** GDBM_GETDIRDEPTH

Return the directory depth, i.e. the number of initial (most significant)
bits in hash value that are interpreted as index to the directory.

** GDBM_GETBUCKETSIZE

Return maximum number of keys per bucket.

** GDBM_GETCACHEAUTO

Return the status of the automatic cache adjustment.

** GDBM_SETCACHEAUTO

Enable or disable automatic cache adjustment.

Best regards,
Sergey
