bug in the Telecom Log Service IDL

  • Key: TLOG-60
  • Legacy Issue Number: 3752
  • Status: closed  
  • Source: Anonymous
  • Summary:

    I have just noticed a bug in the Telecom Log Service IDL. The
    "Log" interface defined in the "DsLogAdmin" module defines "set_qos"
    and "get_qos" operations. And, the DsNotifyLogAdmin::NotifyLog
    interface inherits both the DsLogAdmin::Log interface (indirectly,
    through inheritence of DsEventLogAdmin::EventLog) and the
    CosNotifyChannelAdmin::EventChannel interface. Note that the
    CosNotifyChannelAdmin::EventChannel interface inherits from
    CosNotification::QoSAdmin, which also defines "set_qos" and "get_qos"
    operations! This is invalid IDL inheritence as of CORBA 2.3!

    The same problem exists for the DsTypedNotifyLogAdmin::TypedNotifyLog
    interface. It indirectly inherits both DsLogAdmin::Log and
    CosNotification::QoSAdmin, and thus two versions of "set_qos" and
    "get_qos".

    There are a couple of possible solutions to this problem, but perhaps
    the easiest would be to simply rename the "set_qos" and "get_qos" operations
    defined in the Log interface as "set_log_qos" and "get_log_qos",
    respectively. If only there were an RTF that could do this...

Clarify specification text in section 3.4 Log Generated Events

  • Key: TLOG-25
  • Legacy Issue Number: 2666
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: The specification text is unclear and should make a note in
    section "3.4 Log Generated Events" to explain that the manner
    in which logs send log generated events to their corresponding
    log factories is an implementation detail.

    The idea is that applications (log/LogFactory clients) are only consumers
    of log emitted events, they do not send events to the factory. Therefore, the
    LogFactory does not need to expose the SupplierAdmin interface. How the log
    actually forwards events to the factory is left up to the implementation -
    use a SupplierAdmin object, or other means.

Argument in CapacityAlarmTresholdList tresholds doesn"t appear in IDL

  • Key: TLOG-24
  • Legacy Issue Number: 2665
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: In the specification text, the BasicLogFactory::create() and
    BasicLogFactory::create_with_id() operations have an extra
    argument, in CapacityAlarmThresholdList thresholds, which does
    not appear in the specification IDL. The reference to thresholds
    in the specification text should be removed from the definitions
    of BasicLogFactory::create() and BasicLogFactory::create_with_id().

    The paragraphs in the specification text that describe the create()
    and create_with_id() operations for the other log factories
    (ie. EventLogFactory) should explain that they have an additional
    argument, thresholds, besides the ones defined in the BasicLogFactory.

Adopt current OMG style of using CONST

  • Key: TLOG-22
  • Legacy Issue Number: 2663
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: there are a few enums defined in the
    IDL. Perhaps it would be a good idea to adopt the
    current OMG style of using CONST declarations for
    these values as this allows easy extension of the values (which
    enums do not). It is also nice to define the const types
    as signed and to reserve all positive values for OMG
    use and leave the negative values for vendors.

Text unclear to a log"s behavior when off_duty

  • Summary:

    Summary: The specification text is unclear to a log"s behavior when off_duty.
    What should the log do when it"s not functioning due to being
    outside the interval or shut down according to the weekmask? I assume it"s
    still available for adjusting weekmask parameters, but does it just drop
    log requests on the floor?

    Summary: The specification text is unclear to a log"s behavior when disabled.
    If the log is disabled ("due to some run time catastrophy"), how should
    the log respond to requests? Since it is active enough to respond to
    "get_operational_state ()" requests, shouldn"t it throw exceptions? Is it
    allowed to drop log requests on the floor in that case? It could throw a
    LogLocked exception, but in that case, should the log lock when it enters
    the disabled state?

DsLogNotification::ObjectDeletion in Telecom Log Service

  • Key: TLOG-21

  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: Documents: telecom/98-12-04 (text)
    telecom/99-01-05 (IDL)

    In module DsLogNotification, the event to be sent on log deletion is
    defined as

    struct ObjectDeletion

    { Log logref; LogId id; TimeT time; }

    ;

    Here, "logref" is a reference to the Log object that has just been deleted,
    and hence cannot be used for anything – would it be better to abolish this
    field? (Even though doing so would reduce the symmetry with ObjectCreation).

Clarification for untyped events

  • Key: TLOG-32
  • Legacy Issue Number: 2725
  • Status: closed  
  • Source: Anonymous
  • Summary:

    A clarification needs to be made when untyped events are inserted and retrieved
    from a typed log.

    A client can use the standard "push" operation with a TypedProxyPushConsumer as
    well as the type event operations defined on the interface generating the event.
    What happens if a client invokes the typed_query() operation where some of the events
    that pass the constraint were "push"ed as untyped events? Are those records ignored?
    Are the type related fields of the TypedEventRecord left empty? Should we raise an exception?

Availability status under wrap condition

  • Key: TLOG-36
  • Legacy Issue Number: 2753
  • Status: closed  
  • Source: Fujitsu ( Tom Rutt)
  • Summary:

    The AB raised an issue regarding an ambiguity on the proper value
    for the availability status, when the log is in the wrap condition.
    The FTF editor added the following sentence at the top of page 2-12
    of to telecom/99-05-01, in an effort to clarify the AB issue:

    "When a log is full its availability status will change to
    indicate the log full condition. If a log's full action is set to
    'wrap', it will never be in 'full' condition."

    This same ambiguity was discussed the ITU-T group which
    originally wrote the X.735 spec, and their proposed resolution
    has the opposite affect:

    Add the following explanation to the availability status value as a
    separate para after the text discussing wrap event behaviour :

    "The availability status indicates "logfull" when the capacity of
    the log is exceeded. In the case where halt behaviour is
    specified for the log the value implies no more records can be
    added. If wrap behaviour is specified, the value continues to
    remain as log full even though forthcoming records will be added
    by overwriting existing records. The wrap mode combined with
    logfull condition indicates that old records are lost as
    overwriting takes place. If records are deleted from the log, the
    logfull status value is removed from the availability status in
    either halt or wrap mode."

    The reason the ITU group has recommended "full" status is that it
    gives the information that records are being overwritten. When
    the log is full, records will be lost in response to forthcoming
    events. In Halt mode new records are not logged (i.e., lost),
    while in the wrap mode the oldest records are overwritten (i.e.,
    lost). If a client comes and deletes records, then
    availabilitystatus can be reset. Otherwise one needs to have a
    different behaviour for halt and wrap in terms of the value for
    availability status.

Reset of Capacity Alarm Threshold under wrap condition

  • Key: TLOG-37
  • Legacy Issue Number: 2754
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: This behaviour does not seem correct. Under a wrap condition, a
    capacity alarm gauge threshold should retrigger once in each
    period between wraps, but if the counter resets every time it
    crosses the thresold it will trigger more often. Thus the reset
    of the gauge , under wrap conditions, needs to be reworded as
    follows:

    "
    When a log object is created with the wrap option the capacity
    threshold alarms are triggered as if coupled to a gauge that
    counts from zero to the highest capacity of the log defined
    (reached each time the log wraps) and then resets to zero.

    If a log wraps, and no records are deleted to free space,
    capacity threshold events shall be emitted only when all the
    records in the log prior to the previous wrap occurance are
    completely overwritten. In other words, the gauge threshold is
    reset to zero each time the end of log marker is crossed by the
    addition of a new log record. For example if a log has a capacity
    of 2 Gigabytes a wrap event will occur only when every time 2
    Gigabytes of data have been written to the log.
