Editing Berkeley DB (section)

==Open-source programs still using Berkeley DB==
BDB was once very widespread, but usage dropped steeply from 2013 (see [[#Licensing|licensing section]]). Notable software that still uses Berkeley DB for data storage include:
* [[Bogofilter]] – A free/open-source [[spam (email)|spam]] filter that saves its wordlists using Berkeley DB by default.<ref>{{Cite web |title=bogofilter -- Fast Bayesian Spam Filter Code (Git) |url=https://sourceforge.net/p/bogofilter/git/ci/main/tree/bogofilter/README |access-date=2024-05-17 |website=sourceforge.net}}</ref>
* [[Citadel/UX]] – A [[collaborative software]] (messaging and groupware) that is directly descended from the [[Citadel (software)|Citadel]] family of programs, which became popular in the 1980s and 1990s as a [[bulletin board system]] platform.
* [[Sendmail]] – A free/open-source [[Message transfer agent|MTA]], first released in 1983 for Linux/Unix systems.
* [[Spamassassin]] – A free/open-source anti-spam application.

Open-source operating systems and languages such as [[Perl]] and [[Python (programming language)|Python]] still support old BerkelyDB interfaces. The [[FreeBSD]] and [[OpenBSD]] operating systems ship Berkeley DB 1.8x to support the <code>dbopen()</code><ref name="FreeBSD Manual Pages">{{cite web | title=dbopen(3) | website=FreeBSD Manual Pages | url=https://man.freebsd.org/cgi/man.cgi?query=dbopen&sektion=3&apropos=0&manpath=FreeBSD+13.1-RELEASE+and+Ports | access-date=2023-04-18}}</ref><ref name="dbopen(3)">{{cite web | title=OpenBSD manual pages | website=dbopen(3) | url=https://man.openbsd.org/dbopen.3 | access-date=2023-04-18}}</ref> operating system call used by password programs such as <code>pwb_mkdb</code>.<ref name="OpenBSD manual pages">{{cite web | title=pwd_mkdb(8) | website=OpenBSD manual pages | url=https://man.openbsd.org/pwd_mkdb | access-date=2023-04-18}}</ref> Linux operating systems, including those based on Debian,<ref name="Webmaster">{{cite web | last=Webmaster | first=Debian | title=Debian -- Details of package libdb5.3 in sid | website=Debian -- Packages | url=https://packages.debian.org/en/sid/amd64/libdb5.3 | access-date=2023-04-18}}</ref> and Fedora<ref name="src.fedoraproject.org">{{cite web | title=Overview - rpms/libdb | website=src.fedoraproject.org | url=https://src.fedoraproject.org/rpms/libdb | access-date=2023-04-18}}</ref> ship Berkeley DB 5.3 libraries.
