Admin Module

This XQuery Module contains functions for performing admin-centric operations such as managing database users and log data.

Conventions

All functions in this module are assigned to the http://basex.org/modules/admin namespace, which is statically bound to the admin prefix.
All errors are assigned to the http://basex.org/errors namespace, which is statically bound to the bxerr prefix.

Functions

admin:sessions

Signatures	admin:sessions() as element(session)*
Summary	Returns an element sequence with all currently opened sessions, including the user name, address (IP:port) and an optionally opened database. The output of this function and the SHOW SESSIONS command is similar.
Examples	admin:sessions() may e.g. return <session user="admin" address="127.0.0.1:6286" database="factbook"/>

admin:logs

Signatures	admin:logs() as element(file)* admin:logs($date as xs:string) as element(entry)* admin:logs($date as xs:string, $merge as xs:boolean) as element(entry)*
Summary	Returns Logging data compiled by the database or HTTP server: If no argument is specified, a list of all log files will be returned, including the file size and date. If a $date is specified, the contents of a single log file will be returned. If $merge is set to true, related log entries will be merged. Please note that the merge might not be 100% successful, as log entries may be ambiguous.
Examples	admin:logs() may return <file size="834367"/>2015-01-23</file> if a single log file exists. admin:logs() ! admin:logs(.) lists the contents of all log files.

admin:write-log

Signatures	admin:write-log($text as xs:string) as empty-sequence()
Summary	Writes a string to the database logs, along with current user data (timestamp, user name). If the function is called in a web application or a database client, the IP will be logged. Otherwise, the string STANDALONE will be logged.

Signatures	admin:delete-logs($date as xs:string) as empty-sequence()
