slapd.replog - slapd replication log format

slapd.replog slapd.replog.lock

The file slapd.replog is produced by the stand-alone LDAP daemon, slapd(8), when changes are made to its local database that are to be propagated to one or more replica slapds. 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(8), 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.

	replica: truelies.rs.itd.umich.edu
	replica: judgmentday.rs.itd.umich.edu
	time: 797612941
	dn: cn=Babs Jensen,dc=example,dc=com
	changetype: add
	objectclass: person
	cn: babs
