.SH NAME
|
|
slapd.replog \- slapd replication log format
|
|
.SH SYNOPSIS
|
|
slapd.replog
|
|
slapd.replog.lock
|
|
.SH DESCRIPTION
|
|
.LP
|
|
The file slapd.replog is produced by the stand-alone LDAP daemon,
|
|
.IR slapd ,
|
|
when changes are made to its local database that are to be
|
|
propagated to one or more replica
|
|
.IR slapd s.
|
|
The file consists of
|
|
zero or more records, each one corresponding to a change, addition,
|
|
or deletion from the
|
|
.I slapd
|
|
database. The file is meant to be read
|
|
and processed by
|
|
.IR slurpd ,
|
|
the stand-alone LDAP update replication daemon. The records are
|
|
separated by a blank line. Each record has the following format.
|
|
.LP
|
|
The record begins with one or more lines indicating the replicas
|
|
to which the change is to be propagated:
|
|
.LP
|
|
.nf
|
|
replica: <hostname[:portnumber]>
|
|
.fi
|
|
.LP
|
|
Next, the time the change took place given, as the number of seconds since
|
|
00:00:00 GMT, Jan. 1, 1970, with an optional decimal extension, in order
|
|
to make times unique. Note that slapd does not make times unique, but
|
|
slurpd makes all times unique in its copies of the replog files.
|
|
.LP
|
|
.nf
|
|
time: <integer[.integer]>
|
|
.fi
|
|
.LP
|
|
Next, the distinguished name of the entry being changed is given:
|
|
.LP
|
|
.nf
|
|
dn: <distinguishedname>
|
|
.fi
|
|
.LP
|
|
Next, the type of change being made is given:
|
|
.LP
|
|
.nf
|
|
changetype: <[modify|add|delete|modrdn]>
|
|
.fi
|
|
.LP
|
|
Finally, the change information itself is given, the format of which
|
|
depends on what kind of change was specified above. For a \fIchangetype\fP
|
|
of \fImodify\fP, the format is one or more of the following:
|
|
.LP
|
|
.nf
|
|
add: <attributetype>
|
|
<attributetype>: <value1>
|
|
<attributetype>: <value2>
|
|
...
|
|
-
|
|
.fi
|
|
.LP
|
|
Or, for a replace modification:
|
|
.LP
|
|
.nf
|
|
replace: <attributetype>
|
|
<attributetype>: <value1>
|
|
<attributetype>: <value2>
|
|
...
|
|
-
|
|
.fi
|
|
.LP
|
|
Or, for a delete modification:
|
|
.LP
|
|
.nf
|
|
delete: <attributetype>
|
|
<attributetype>: <value1>
|
|
<attributetype>: <value2>
|
|
...
|
|
-
|
|
.fi
|
|
.LP
|
|
If no \fIattributetype\fP lines are given, the entire attribute is to be
|
|
deleted.
|
|
.LP
|
|
For a \fIchangetype\fP of \fIadd\fP, the format is:
|
|
.LP
|
|
.nf
|
|
<attributetype1>: <value1>
|
|
<attributetype1>: <value2>
|
|
...
|
|
<attributetypeN>: <value1>
|
|
<attributetypeN>: <value2>
|
|
.fi
|
|
.LP
|
|
For a \fIchangetype\fP of \fImodrdn\fP, the format is:
|
|
.LP
|
|
.nf
|
|
newrdn: <newrdn>
|
|
deleteoldrdn: 0 | 1
|
|
.fi
|
|
.LP
|
|
where a value of 1 for deleteoldrdn means to delete the values
|
|
forming the old rdn from the entry, and a value of 0 means to
|
|
leave the values as non-distinguished attributes in the entry.
|
|
.LP
|
|
For a \fIchangetype\fP of \fIdelete\fP, no additional information
|
|
is needed in the record.
|
|
.LP
|
|
The format of the values is the LDAP Directory Interchange Format
|
|
described in
|
|
.BR ldif (5).
|
|
.LP
|
|
Access to the \fIslapd.replog\fP file is synchronized through the
|
|
use of
|
|
.BR flock (3)
|
|
on the file \fIslapd.replog.lock\fP. Any process
|
|
reading or writing this file should obey this locking convention.
|
|
.SH EXAMPLE
|
|
The following sample \fIslapd.replog\fP file contains information
|
|
on one of each type of change.
