; Murmur configuration file.
;
; General notes:
; * Settings in this file are default settings and many of them can be overridden
;   with virtual server specific configuration via the Ice or DBus interface.
; * Due to the way this configuration file is read some rules have to be
;   followed when specifying variable values (as in variable = value):
;     * Make sure to quote the value when using commas in strings or passwords.
;        NOT variable = super,secret BUT variable = "super,secret"
;     * Make sure to escape special characters like '\' or '"' correctly
;        NOT variable = """ BUT variable = "\""
;        NOT regex = \w* BUT regex = \\w*

; Path to database. If blank, will search for
; murmur.sqlite in default locations or create it if not found.
database={{ murmur_database }}

; Murmur defaults to using SQLite with its default rollback journal.
; In some situations, using SQLite's write-ahead log (WAL) can be
; advantageous.
; If you encounter slowdowns when moving between channels and similar
; operations, enabling the SQLite write-ahead log might help.
;
; To use SQLite's write-ahead log, set sqlite_wal to one of the following
; values:
;
; 0 - Use SQLite's default rollback journal.
; 1 - Use write-ahead log with synchronous=NORMAL.
;     If Murmur crashes, the database will be in a consistent state, but
;     the most recent changes might be lost if the operating system did
;     not write them to disk yet. This option can improve Murmur's
;     interactivity on busy servers, or servers with slow storage.
; 2 - Use write-ahead log with synchronous=FULL.
;     All database writes are synchronized to disk when they are made.
;     If Murmur crashes, the database will be include all completed writes.
;sqlite_wal=0

; If you wish to use something other than SQLite, you'll need to set the name
; of the database above, and also uncomment the below.
; Sticking with SQLite is strongly recommended, as it's the most well tested
; and by far the fastest solution.

; If you want to use ZeroC Ice to communicate with Murmur, you need

; Please see the ICE documentation on how to specify endpoints.

; Ice primarily uses local sockets. This means anyone who has a
; user account on your machine can connect to the Ice services.
; You can set a plaintext "secret" on the Ice connection, and
; any script attempting to access must then have this secret
; (as context with name "secret").
; Access is split in read (look only) and write (modify)
; operations. Write access always includes read access,
; unless read is explicitly denied (see note below).
;
; Note that if this is uncommented and with empty content,
; access will be denied.

;
; After setting this option, it is recommend that you inspect your Murmur log
