SLAPD.REPLOG (5)
slapd replication log format
SYNOPSIS
slapd.replog
slapd.replog.lock
DESCRIPTION
The file slapd.replog is produced by the stand-alone LDAP daemon,
slapd ,
when changes are made to its local database that are to be
propagated to one or more replica
slapd s.
The file consists of
zero or more records, each one corresponding to a change, addition,
or deletion from the
slapd
database. The file is meant to be read
and processed by
slurpd ,
the stand-alone LDAP update replication daemon. The records are
separated by a blank line. Each record has the following format.
The record begins with one or more lines indicating the replicas
to which the change is to be propagated:
replica: <hostname[:portnumber]>
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.
time: <integer[.integer]>
Next, the distinguished name of the entry being changed is given:
dn: <distinguishedname>
Next, the type of change being made is given:
changetype: <[modify|add|delete|modrdn]>
Finally, the change information itself is given, the format of which
depends on what kind of change was specified above. For a changetype
of modify, the format is one or more of the following:
add: <attributetype>
<attributetype>: <value1>
<attributetype>: <value2>
...
-
Or, for a replace modification:
replace: <attributetype>
<attributetype>: <value1>
<attributetype>: <value2>
...
-
Or, for a delete modification:
delete: <attributetype>
<attributetype>: <value1>
<attributetype>: <value2>
...
-
If no attributetype lines are given, the entire attribute is to be
deleted.
For a changetype of add, the format is:
<attributetype1>: <value1>
<attributetype1>: <value2>
...
<attributetypeN>: <value1>
<attributetypeN>: <value2>
For a changetype of modrdn, the format is:
newrdn: <newrdn>
deleteoldrdn: 0 | 1
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.
For a changetype of delete, no additional information
is needed in the record.
The format of the values is the LDAP Directory Interchange Format
described in
ldif (5).
Access to the slapd.replog file is synchronized through the
use of
flock (3)
on the file slapd.replog.lock. Any process
reading or writing this file should obey this locking convention.

The following sample slapd.replog file contains information
on one of each type of change.
