The libstdc++ package contains a rewritten standard compliant GCC Standard C++ Library.
A general purpose cryptography library with TLS implementation
The openssl-libs package contains the libraries that are used by various applications which support cryptographic algorithms and protocols.
The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, exit and more.
MariaDB is a multi-user, multi-threaded SQL database server. It is a client/server implementation consisting of a server daemon (mariadbd) and many different client programs and libraries. This package contains the MariaDB server and some accompanying files and directories. MariaDB is a community developed fork from MySQL.
PCRE2 is a re-working of the original PCRE1 library to provide an entirely new API. Since its initial release in 2015, there has been further development of the code and it now differs from PCRE1 in more than just the API. PCRE2 is written in C, and it has its own API. There are three sets of functions, one for the 8-bit library, which processes strings of bytes, one for the 16-bit library, which processes strings of 16-bit values, and one for the 32-bit library, which processes strings of 32-bit values. Unlike PCRE1, there are no C++ wrappers. The distribution does contain a set of C wrapper functions for the 8-bit library that are based on the POSIX regular expression API (see the pcre2posix man page). These are built into a library called libpcre2-posix. Note that this just provides a POSIX calling interface to PCRE2; the regular expressions themselves still follow Perl syntax and semantics. The POSIX API is restricted, and does not give full access to all of PCRE2's facilities.
The mariabackup tool for physical online backups
MariaDB Backup is an open source tool provided by MariaDB for performing physical online backups of InnoDB, Aria and MyISAM tables. For InnoDB, "hot online" backups are possible.
