Issues Descriptions

What should an ORB do when it does not find any profile in an IOR

  • Legacy Issue Number: 3234
  • Status: closed  
  • Source: Thematix Partners LLC ( Jishnu Mukerji [X] (Inactive))
  • Summary:

    As per the discussion in the Interop RTF meeting in Mesa, it was decided to
    split up 2457 into two parts as follows:

    Part 1: What should an ORB do when it does not find any profile in an IOR that
    it is able to use? This should usually not happen in a CORBA interoperability
    compliant ORB, but the possibility should be covered in the spec anyway.

Standard System Exception minor codes missing in Chapter 13

  • Legacy Issue Number: 2961
  • Status: closed  
  • Source: Thematix Partners LLC ( Jishnu Mukerji [X] (Inactive))
  • Summary:

    Chapter 13 (formal/99-07-17) is missing specification of minor codes for many
    the standard system exceptions that are specified to be raised under various
    circumstances.

  • Reported: CORBA 2.3.1 — Tue, 26 Oct 1999 04:00 GMT

Component ids in 13.6.2.2

  • Legacy Issue Number: 2914
  • Status: closed  
  • Source: Floorboard Software ( Jonathan Biggar)
  • Summary:

    Also, 13.6.2.2 claims "ORB services are assigned component identifiers
    in a namespace that is distinct from the the profile identifiers".
    What is the significance of this statement?

  • Reported: CORBA 2.3.1 — Wed, 22 Sep 1999 04:00 GMT

Transmission of type codes across 2.2/2.3 boundaries

  • Legacy Issue Number: 1962
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: Suppose I am using a 2.3 ORB and receive a type code from a 2.2 ORB without
    a repository ID. What am I supposed to do if I want to send that type
    code somewhere else? (This could happen for an event channel, for example.)

  • Reported: CORBA 2.2 — Wed, 16 Sep 1998 04:00 GMT

LOCATE_FORWARD_PERM and hash()

  • Legacy Issue Number: 1486
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: With GIOP 1.2, we added LOCATE_FORWARD_PERM to the protocol, which
    permanently replaces an IOR with a different one. I believe we shouldn"t
    have done this because it creates an internal inconsistency. The
    Object::hash() operation requires that the hash value for a reference
    must be immutable during its life time. (Unfortunately, "life time" isn"t
    well-defined.)

Conflict between POA & Exceptions spec for OBJECT_NOT_EXIST

  • Legacy Issue Number: 3919
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    There is a conflict between the specification of the OBJECT_NOT_EXIST
    exception and its use in the POA spec. The exception definition says
    that OBJECT_NOT_EXIST means that an object has gone away forever, and
    that clients should tidy up references to it. However, the POA spec
    requires an ORB to raise this exception in cases where the object may
    not have gone away for ever.

    In particular, 11.2.6 (in the 5 May 2.4 Draft) requires an ORB to raise
    OBJECT_NOT_EXIST if request comes in for a child POA that is not active
    and was not activated by the application's POA Activator. While this
    may mean that the object has gone away for ever, it doesn't always
    mean that. For example:

    1) If the server admin has stuffed port number allocations, a server
    may accidentally get requests for POAs that it doesn't know about.

    2) If the server has been incorrectly (re-)built one of its "static"
    child POAs might not be activate.

    3) If the server is buggy and / or its persistent state is flakey,
    it may temporarily fail to dynamically activate a child POA.

    In each case, the problem MAY be one that can be fixed, allowing the
    missing POA to reappear in a few minutes. It is therefore inappropriate
    for the ORB to be telling the client that the Object has gone away for
    ever.

    For what it is worth, I think the ORB should raise another exception,
    say OBJ_ADAPTER, in the default case. It might raise OBJECT_NOT_EXIST
    if it (somehow) tracks the lifecycle of transient and / or persistent
    POAs, or if the application code tells it the POA no longer exists.
    Note: I'm not suggesting that an ORB be required to support such things.

    The other alternative is to change the definition of OBJECT_NOT_EXIST
    to remove the implication that the object has gone away forever and
    the suggestion that clients should throw away references to the object.
    [I think that's wrong though ...]

    should the request block, or can it be rejected?

Null valuetypes not supported by DynValue

  • Legacy Issue Number: 3250
  • Status: closed  
  • Source: IONA ( Mark Spruiell)
  • Summary:

    DynValue is missing support for null valuetypes. There is no
    way to determine whether a DynValue represents a null valuetype,
    nor is there any way to dynamically construct an Any containing
    a null valuetype.

    Proposed resolution:

    Add the following operations to the DynValue interface:

    boolean is_null();
    void set_to_null();
    void set_to_value();

    And replace the description of the interface with the following text:

    The DynValue interface can represent both null and non-null
    valuetypes. For a DynValue representing a non-null valuetype, the
    DynValue's components comprise the public and private members of
    the valuetype, including those inherited from concrete base valuetypes,
    in the order of definition. A DynValue representing a null valuetype
    has no components and a current position of -1.

    boolean is_null();

    The is_null operation returns TRUE if the DynValue represents
    a null valuetype.

    void set_to_null();

    The set_to_null operation changes the representation of a DynValue
    to a null valuetype. Specifically, the current components of the DynValue
    are destroyed, component_count returns zero and the current position is
    set to -1.

    void set_to_value();

    The set_to_value operation changes the representation of a DynValue
    to a non-null valuetype. The state of the DynValue is initialized
    exactly as if create_dyn_any_from_type_code had been invoked.
    The set_to_value operation has no effect when invoked on a DynValue
    representing a non-null valuetype.

    The remaining operations of the DynValue interface have equivalent
    semantics to DynStruct. When invoked on a DynValue representing a
    null valuetype, get_members and get_members_as_dyn_any return an empty
    sequence.

Expected behavior of POA configured with ServantLocator receiving LocateRe

  • Legacy Issue Number: 2791
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: This is an issue with the Portable Object Adapter:

    If a POA configured with a ServantLocator receives a LocateRequest, what
    is the expected behavior? A ServantLocator expects to receive an operation
    name as a parameter to preinvoke() and postinvoke(), but there is no
    operation name in a LocateRequest.

    We could just return a true response to the LocateRequest and not involve
    the ServantLocator. That might mislead the sender though. If the sender
    received a true response and then sent a message they might get an
    OBJECT_NOT_EXIST exception back.

    We could pass an operation name like "_locate" to the manager. That would
    let the manager know that a location request was being processed, and the
    underscore would signify that it is an internal message since it"s not a
    _get or _set.

IDL format for RepositoryId

    Following statement in CORBA V2.3 (06/1999),

    the OMG IDL format for Repository IDs:

    >> The RepositoryId consists of three components, separated by

    The first component is the format name, "IDL."

    The second component is a list of identifiers, separated by
    "/" characters.

    These identifiers are arbitrarily long sequences of alpha-
    betic, digit, underscore ("_"), hyphen ("-"), and period (".")
    characters. Typically, the first identifier is a unique prefix,
    and the rest are OMG IDL Identifiers that make up the scoped

    • Furthermore, I propose be more specific on the definition
      of the Repository Id. The above definition does not

DynUnion incomplete

  • Legacy Issue Number: 4005
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    given the a DynUnion value, I want to find out whether the discriminator
    currently indicates the default case. For example:

    union u switch (long)

    { case 0: long l; case 1: char c; case 2: double d; default: float f; }

    ;

    For this union, I want to know whether the default member is active, that is,
    whether the discriminator has a value other than 0, 1, or 2.

    Finding out whether the discriminator indicates the default case is currently
    rather difficult. I have to:

    1) get the union type code
    2) collect the values of all the explicit case labels from
    the type code
    3) check if the discriminator currently has a value that is not
    one of the explicit case labels values

    It would be much nicer to add the following to DynUnion:

    interface DynUnion : DynAny

    { boolean is_set_to_default_case(); // ... }

    ;

    The is_set_to_default_case operation returns true if a union has
    an explicit default label and the discriminator value does not
    match any of the union's other case labels.

#pragma version issue

  • Legacy Issue Number: 4016
  • Status: closed  
  • Source: AT&T ( Duncan Grisby)
  • Summary:

    In the CORBA 2.4 spec, chapter 10, the definition of #pragma ID has
    been modified so that later re-declarations of the same ID for a type
    are permitted. Before, it was explicitly an error to use #pragma ID
    for a type more than once, even if the same IDs were given.

    The section of #pragma version has not been updated. This means that
    handling of the two similar pragmas is now inconsistent:

    interface A {};
    #pragma ID A "LOCAL:foo"
    #pragma ID A "LOCAL:foo" // OK in 2.4, error in 2.3

    interface B {};

Servant deactivation callback?

  • Legacy Issue Number: 4014
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    Consider a servant for a persistent object that sits in front of a database.
    Assume a simple implementation model, using RETAIN and
    USE_ACTIVE_OBJECT_MAP_ONLY.

    We have n CORBA objects with n servants, and each servant implements
    its operations by reading/writing through to the persistent store, possibly
    also caching some state and maintaining other resources, such as database
    connections or memory buffers.

    I want to implement a life cycle destroy() operation. In the body of
    destroy, I have to write something like:

    void
    Foo_impl::
    destroy() throw(CORBA::SystemException)

    { my_poa->deactivate_object(my_oid); // Cannot remove database record here or do any other // cleanup. }

    The problem is that the servant can't simply blow things away at that
    point because there may be other operations running concurrently in the
    same servant, and those operations would get awfully surprised if their
    state suddenly disappeared.

    So, I delay reclaiming resources and deleting the database record until
    the servant becomes idle. In C++, that's no problem. Eventually, the
    servant's AOM entry disappears and (at least if I use reference-counted
    servants) that triggers the destructor of the servant, and I can
    clean up in the destructor.

    However, it appears that this doesn't work for other languages because they
    may not have destructors or, like Java, make no guarantees about when
    the destructor will be called.

    The problem is that there is no way for me to find out at what
    point the servant becomes idle, so that I could clean up.

    I think we need a callback from the ORB to the server application code that
    notifies the server when a servant finally becomes idle. Otherwise, it is
    pretty much impossible to implement life cycle support in languages other
    than C++, especially for threaded servers.

why was is_abstract added to structs in CORBA IR?

  • Summary:

    I was wondering if anyone can explain the rationale for adding the field

    2.3 Interface Repository specification. (I do know about abstract interfaces,

    Basically, a CORBA 2.3 client using stubs compiled from the latest IDL cannot
    interoperate using IIOP with the Interface Repository of a pre-CORBA 2.3 ORB,
    because virtually any client of the IR will want to obtain a
    FullInterfaceDescription from an InterfaceDef, and a pre-CORBA 2.3 ORB will
    not marshal the 'is_abstract' field for the description struct, thereby the
    CORBA 2.3 client will fail to unmarshal the struct.

Absence of Wide Character Code Set

  • Legacy Issue Number: 3576
  • Status: closed  
  • Source: Anonymous
  • Summary:

    CORBA is inconsistent on how to deal with the lack wide character code set
    information in an IOR and the codes set service context.

    When a server receives a service context without a wide character code set
    specified, then it is supposed to raise BAD_PARAM when it receives wide
    characters data from the client.

    However a client is supposed to raise INV_OBJREF if the IOR is missing
    from the server's native wchar code set . In CORBA 2.3, section13.7.2.6,
    "Code Set Negotiation", it says, "... a server that supports interfaces
    that
    use wide character data is required to specify its native wchar code set;
    if
    one is not specified, then the client-side ORB raises exception
    INV_OBJREF."

    This requires a client to know whether a server supports interfaces that
    use
    wide character data at the time the client receives an IOR. To determine
    this when the first IOR is received is a burdensome task. The client orb
    would be forced to apply an exhaustive examination, such scanning all of
    the
    server's IDL bindings or the contents of the IFR looking for wchar types.
    Additionally the client may need to determine if some Any might flow
    containing wchar data.

    I propose that the client's behavior be changed to match the server's. If
    any wide character data is encountered and the server's IOR was missing
    the native wchar code set, (which would cause the wide character
    transmission
    code set to not be negotiated), the client should raise BAD_PARAM.

    This will allow common marshal and demarshal code to be independent of
    whether it is running as a client or server. It also allows users to not
    configure
    wide character code sets if they know they aren't using them.

ORB throwing exception if it finds unknown service context

  • Legacy Issue Number: 3565

  • Source: UBS ( Urs Kuenzler)
  • Summary:

    Why does it make sense at all to allow an ORB to throw an exception if it finds
    a service context it does not "understand"? This is not very helpful for
    interoperability. Would a sending ORB have to handle this exception and resend
    the same request without context to allow to interoperate with an ORB throwing
    BAD_PARAM in this case? If an unknown service context is sent with a reply, the
    receiving ORB would throw BAD_PARAM at the caller (even if it got a valid
    reply). The originator of the service context wouldn't even know.

Wrong minor code specified in Chapter 13

  • Legacy Issue Number: 3561
  • Status: closed  
  • Source: Thematix Partners LLC ( Jishnu Mukerji [X] (Inactive))
  • Summary:

    In document ptc/00-03-02 on page 13-30 in the last bullet on that page it says: "If a system
    exception is raised , it shall be BAD_PARAM with an OMG standard minor code of 1".

    This cannot be right because the OMG standard minor code of 1 for BAD_PARAM is assigned to "failure
    to register, unregister or lookup value factory."

    I recommend that we change this minor code to a new one that is properly allocated with the
    associated text that reads something like: "Service context not understood". I am still wondering
    though why BAD_PARAM is the correct exception to raise. Wouldn't BAD_CONTEXT be more appropriate?

    In any case we have to change the minor code, even if we cannot make up our minds about which
    exception.

marshalling of null values unclear

  • Summary:

    Description: Instruction for marshalling of null values is missing (in

    ptc/99-03-07). Issues include:

    • The null_tag token is included in the grammar, but it's purpose is
      described nowhere. If this is the intended encoding of any null value,
      how are the typing semantics of values to be maintained? For example,
      which type-specific factory is to be used to create the null value to
      be
      passed to the servant? How are the truncation semantics to be
      preserved?
    • There is a statement in 15.3.4.5 that "[t]he tag value 0 is reserved
      for future use". Does this refer to null_tag? (Note that there seems to
      be
      inconsistent use of "tag" within the text.) If so, how are null values
      to be marshalled? The grammar doesn't seem to allow for zero length
      value_data.

CDR Encapsulation Issue

  • Legacy Issue Number: 3096
  • Status: closed  
  • Source: Camros Corporation ( Jeffrey Marshall)
  • Summary:

    In the current 2.3 spec section 15.3.3 on Encapsulation
    states in the last paragraph:
    "Note that this gaurantees a four-octet alignment of the
    start of all encapsulated data within GIOP messages and
    nested encapsulations(2)"

    There's a foot note on the bottom of the page stating:
    (2) "Accordingly, in cases where encapsulated data holds
    data with natural alignment of greater than four
    octets, some processors may need to copy the octet
    data before removing it from the encapsulation. The
    GIOP protocol itself does not require encapsulation
    of such data"

    Here's the problem, the latest revisions have added support
    for a "[unsigned] long long" being the discriminator type
    within a union and therefore the encapsulated information
    for a tk_union TypeCode could have alignment needs of eight,
    not four.

    The footnote needs to be revised to indicate that copying
    could be necessary for some type code indirections or at
    least the sentence stating that "GIOP problem itself..."
    should be removed/revised. Of course we could try to
    remove support for "long long" discriminators....

    Some of the interoperability testing we've been doing
    indicates that all but one vendor who supports long long
    discriminator types are not doing things correctly...

Preserving unencapsulated information

  • Legacy Issue Number: 3327
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    Page 15-50 of 2.3.1:

    ORBs that suport only version 1.1. or 1.2 IIOP profiles must
    ignore, but preserve, any data in the profile that occurs
    after the components member.

    A 1.2 ORB is obliged to ignore, but preserve, any information that follows
    the components member in 1_1 profile body. I think the cost of implementing
    this is quite high. What follows after the components member is not in
    a separate encapsulation. So, an ORB that receives an IOR that indeed has
    data after the components member doesn't understand anything about that data
    and therefore must treat it as a blob of bits.

    However, the IOR might be little-endian and the receiving ORB might be
    big-endian. When the receiving ORB wants to send the IOR back out, it
    can't send it as a big-endian IOR because it can't know how to byte-swap
    the data that follows the components member. That means that a big-endian
    ORB is obliged to remarshal the IOR back as a little-endian IOR.
    That's inconvenient, to say the least.

    I don't think it makes sense to require an ORB to preserve something that
    is not encapsulated, simply because the cost of doing this is high.
    (The ORB has to keep a copy of the marshaled profile around because of
    the trailing bit it doesn't understand.)

Indirection for value types

  • Legacy Issue Number: 3315
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    Section 15.3.4, page 15-18:

    The encoding used for indirection is the same as that used for
    recursive TypeCodes (i.e., a 0xffffffff indirection marker
    followed by a long offset (in units of octets) from the beginning
    of the long offset).

    [...]

    Indirections may refer to any preceding location in the GIOP
    message, including previous fragments if fragmentation is used.
    This includes any previously marshaled parameters.

    The beginning of the section ("is the same as that used for recursive
    TypeCodes") is in conflict with what appears at the end ("refer to any
    preceding location in the GIOP message [...]. This includes any previously
    marshaled parameters.")

    This is incorrect because the indirection for type codes does not permit
    indirections that span type code boundaries (page 15-27):

    The indirection applies only to TypeCodes nested within
    some "top-level" TypeCode. Indirected TypeCodes are not
    "freestanding," but only exist inside some other encoded TypeCode.

    I would suggest to rephrase the first part of what is on page 15-18
    to avoid saying that the indirection is the same as for type codes
    because that's simply not the case.

chunked value encoding:

  • Summary:

    a chunk can be followed by:

    1. a new chunk (starting with its size tag)

    2. a new value (value_tag | 0 | value_ref)

    (valueref = 0xffffffff)
    3. an end tag
    (0x80000000 <= end_tag <= 0xffffffff)

    A value indirection and a "top-level" end tag, both have the same tag (0xffffffff).
    Consequently, the 0xffffffff tag marks the end of the current value but it is not clear whether or not a new value (indirection) has started.

    An example where this situation occurs is a ring buffer that is chunked encoded.

Supporting TAG_MULTIPLE_COMPONENTS

  • Summary:

    I have a question on how can ORB vendor support profile with ID

    enough information to drive a complete invocation. Let us say we have an
    IOR with one profile and the ID is TAG_MULTIPLE_COMPONENTS. As per
    13.6.2.2, the profile body in this case contains a
    MultipleComponentProfile. Let us again assume that there is only one
    TaggedComponent with component id of TAG_CODE_SETS and its component
    data.

    I just misinterpret the spec completely?

GIOP version and CloseConnection

  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    I believe that, at some point, we decided that it is legal to send
    request for different GIOP versions over the same connection. Could someone
    please confirm or deny? (My memory is a bit hazy on the details.)

    At any rate, careful scrutiny of the spec does not reveal any words that would
    either state that separate connections must be used for different GIOP versions
    or that they can share a single connection. A definite statement is required
    either way.

    Assuming that different GIOP versions can indeed coexist on the same
    connection, we get an interesting problem: for GIOP 1.0 and 1.1, the spec
    disallows a client to send a CloseConnection message; for GIOP 1.2, it
    requires the client to send a CloseConnection message. This begs the question:
    if different GIOP versions can coexist on the same connection, it becomes
    impossible to achieve orderly connection shutdown. Sending a CloseConnection
    message is illegal for GIOP 1.0 and 1.1, whereas it is required for
    GIOP 1.2... So, what's the client to do if multiple GIOP versions are used
    over the same connection?

Transferring Java exception reason string across the wire

  • Legacy Issue Number: 3405
  • Status: closed  
  • Source: International Business Machines ( Russell Butek)
  • Summary:

    Although this is a Java-specific issue, I suspect it will have to be
    decided in interop, therefore I'd like this to be an interop issue. I've
    cc'ed java-rtf since I'm sure they'll be interested.

    System exceptions only have: minor code, completion status. Java
    exceptions all have a reason string as well. This is a potentially
    significant bit of info that is not getting transferred across the wire in
    Java ORB implementations. Our rmi over iiop customers expect this
    information.

    Our suggested solution is to create another service context for a system
    exception reason string. When a system exception occurs, on a Java server,
    the ORB places the reason string into this service context on the reply
    message. On a Java client, the ORB checks for and extracts this string and
    uses it when creating the system exception instance which is propagated to
    the application code. If the service context doesn't exist, the Java ORB
    just does what it does today. Any other client bindings may ignore this
    service context.

    Java bindings do not need to change for this proposal.

    To be more precise (sorta), we need three things:
    1. A new service context ID

    const ServiceId SystemExceptionReason = TBD;

    2. The context data associated with this ID is a CDR encapsulation of a
    string.
    3. Some verbage somewhere describing this.

    Section 15.3.4.5 contains an inconsistency in the description of how end tags

    contains a chunked value (CV1). Should the end tag for CV1 contain a nesting
    depth of -2 or -1?

    The following sentence in the spec seems to imply that the correct value is -2:

    > The end tag is a negative long whose value is the negation of the absolute
    > nesting depth of the value type ending at this point in the CDR stream.

    However the spec also says:

    > The outermost value type will always be terminated by an end tag with a
    > value of -1.

    which is not true if the end tag for CV1 is written as -2, since no end tag
    with a -1 value will be written.

    Proposed resolution:

    Delete the second above sentence from the spec.

    define up to 4096 minor codes for each system exception."

    Section 3.17 - Standard Exceptions - states:

    "Within a vendor assigned space, the assignment of values to minor codes is
    left to the vendor."

    The first dictates that minor code numbers are in the space of each

Chunked GIOP marshalling for variable-length types

  • Legacy Issue Number: 1677
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: Following the discussion of valuetype chunking in the OBV group, I"ve
    been thinking that the arguments advanced for it really apply to all
    the other variable-length types in CORBA (sequences and strings) as
    well as to OBV value types, and wonder if we might try a small change
    to the marshalling rules.

    Currently, we marshal a string (say) by sending the length of the
    string followed by the bytes of the string. If we don"t know the
    string"s length in advance, say because we are reading it from stdin
    or a subprocess, we need to buffer it in memory and send it as one big
    thing. That"s inefficient.

Optimization of LOCATION_FORWARD replies

  • Legacy Issue Number: 1133
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: As of GIOP/IIOP 1.1, if a server wants to have a client
    use some locally hashed down object_key in future requests
    for an object, it must require one of the following:
    a) the client use a LocateRequest in order for the server
    to reply with a forwarded object reference that has
    a hashed down object key.
    b) respond with an OBJECT_FORWARD reply to the request,
    forcing the client to remarshal the request with the
    new target (the forwarded object reference"s key).
    With some already recommended changes to GIOP 1.1,
    such a reply will only require remarshaling the
    message header, but an extra roundtrip is still required.

    This could be avoided by addind a new service context
    to the reply that contains the forward IOR, or a new
    Reply type such as NO_EXCEPTION_AND_FORWARD that
    indicates the first request has succeeded and that
    subsequent requests can use the supplied forward IOR.

Compacting GIOP Messages by using templates

  • Legacy Issue Number: 1131
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: A common server pattern is that of "factory". As a result
    of a request, a Factory returns an object reference.
    Frequently, these object references differ only by a
    small fraction of their full size. For example, object
    references may be exactly the same except for the object_key
    member of a GIOP profile and maybe the repository_id field
    of the IOR. Allowing the factory to return a more compact
    representation of the object reference would yield great
    savings in message size.
    If the server or client can establish a template for filling
    out object references (or possibly any type of data), a
    more compact on-the-wire form can be used for such object
    references once the template is established.

    Indirections are already used in the marshaling of TypeCodes
    to allow compacting of messages. This can be extended
    to also allow indirection for strings. The current
    encoding of a string is the unsigned long number of characters
    in the string, followed by the null-terminated characters
    comprising the string. If we resolve the maximum value
    for unsigned long "0xffffffff" for indirections, the
    next byte can refer to a previously marshaled string.

  • Summary:

    It is probably not a good idea to mandate an implementation for
    Enumeration, since there may be different options for implementing.
    For example, it may be desirable for
    performance reasons to implement a form of lazy Enumeration that does
    not carry with it every element that it can contain, but requiring
    this kind of implementation can be overkill for some
    applications. Given this, Enumeration is defined as an abstract
    valuetype and at least one concrete specialization of it is
    required. In addition, FOR INTEROPERABILITY, at least one STANDARD
    implementation must also be provided so that client stubs and server
    skeletons know how to marshal and unmarshal Enumeration values.

destroy() for local objects

  • Legacy Issue Number: 3236
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    every ORB I know of implements the various destroy() operations on
    local objects (such as policies or DynAny) as a no-op and destroys the local
    object on the final call to release() instead. Yet, the spec still requires
    programmers to call destroy(). The problem with this is that programmers
    can easily end up writing non-portable code without any visible problem.
    Then, when code is moved to another ORB, it is conceivable that it will
    leak objects.

    This isn't very pretty. I think we should get rid of the destroy() calls
    on local objects (possibly with the exception of the ORB object, although
    the entire shutdown issue for that is quite a mess anyway). It doesn't
    make sense to require the programmer to make a destroy() call for something
    that naturally can be reference counted.

Do EJB-mapped attributes go to the ComponentDefault interface?

    When mapping EJB set/get methods to a CCM view, it is not clear whether the

    Issue:
    Set/get method pairs on the EJB remote interface map to IDL attributes, but
    do these attributes end up in the XXXDefault interface or in the XXX
    component definition? Section 8.2.1.2 of the specification seems to imply
    they belong in the XXXDefault interface, but section 5.3.2 says the
    component definition for a basic CCM "shall only contain zero or more
    attribute declarations", which suggests that attributes of a CORBA
    Component belong in the component definition. Also, the mapping in the
    other direction (EJB view of a CCM), described in 8.3.1, suggests that CCM
    attributes are always found in the component definition itself. It appears
    that both versions will work, but this point is worth clarifying.

CCM Issue: Is CCMObject::remove intended to be available to the CCM client?

  • Legacy Issue Number: 3183
  • Status: closed  
  • Source: International Business Machines ( Mr. Ignacio Silva-Lepe)
  • Summary:

    Section 5.12.1 of the spec can be interpreted to mean that the
    CCMObject::remove call is not intended for use by CCM clients; but this is
    inconsistent with the EJB/CCM mapping given in chapter 8.

    Issue:
    The explanation given for the CCMObject::remove call in section 5.12.1 is:
    "This operation is called when a component is about to be destroyed.
    The component
    can perform any cleanup processing required (e.g. releasing resources)
    prior to its
    destruction."
    This explanation can be interpreted to mean that the call is a private call
    from a CCM container to one of its components; if it has this internal
    purpose then it might not be
    intended for use by CCM clients wanting delete the component. However,
    table 8-1 shows that the CCM view of an EJB maps this call to the
    EJBObject.remove()
    method. This implies that the method is intended for client use as the
    EJBObject.remove() is. If so, then it also makes more sense to implement
    the
    CCMHome::remove() method in terms of the EJBObject.remove() method, rather
    than the current mapping which requires an EJB Handle.

    Proposal: (a) Change the text for remove() in 5.12.1 to say: "This
    operation is used to delete a component".
    (b) Change the mapping in table 8-1 for CCMHome::remove to use

Small optimization for the GIOP header

  • Summary:

    I think I found a possible (very minor) optimization for the
    GIOP 1.3 spec, but maybe I'm missing something in GIOP 1.2

    The new <target> field on the RequestHeader_1_2 structure is
    always aligned to a 4 byte boundary, the reserved[3] field ensures
    that. Consequently the discriminant for the TargetAddress union
    does not end on a 4 byte boundary, but will require 2 bytes of padding
    following it, since all the union values in this case start on 4 byte
    boundaries.

    IMHO, using just 1 byte for the reserved[] field, would have
    resulted in more natural alignments. Did I get something wrong here?

    Well, a new Java release is upon us, and with it comes a new CORBA
    implementation. I'm trying Java 2 SE 1.3 CORBA clients against an ILU
    2.0beta1 CosNaming server, and we find that the Java ORB cannot
    reliably connect to the server. Why not? First, we must analyze the
    IOR provided by the ILU service:

    IOR:000000000000002849444C3A6F6D672E6F72672F436F734E616D696E672F4E616D696E67436F6E746578743A312E300000000002000000000000002F0001000000000016776174736F6E2E706172632E7865726F782E636F6D00270F0000000B4E616D6553657276696365000000000100000024000100000000000100000001000000140001001800010001000000000001010000000000

    If we look at this (those who've received it un-truncated) we find that it advertises the following:

    _IIOP_ParseCDR: byte order BigEndian, repository id <IDL:omg.org/CosNaming/NamingContext:1.0>, 2 profiles
    _IIOP_ParseCDR: profile 1 is 47 bytes, tag 0 (INTERNET), BigEndian byte order
    _IIOP_ParseCDR: profile 2 is 36 bytes, tag 1 (MULTIPLE COMPONENT), BigEndian byte order
    (iiop.c:parse_IIOP_Profile): bo=BigEndian, version=1.0, hostname=watson.parc.xerox.com, port=9999, object_key=<NameService>
    (iiop.c:parse_IIOP_Profile): encoded object key is <NameService>

    (iiop.c:parse_MultiComponent_Profile): native codeset for CHARACTER is 00010100, with 0 converters

    That is, there's a vanilla Internet profile (bo=BigEndian,
    version=1.0, hostname=watson.parc.xerox.com, port=9999,
    object_key=<NameService>), plus a Multicomponent profile, noting that
    the ILU ORB's native codesets are Latin-1 and UCS-2.

    OK, great. Now we get the first message from the Java ORB:

    Note that we are seeing a CodeSets service context, even though the
    request is GIOP 1.0. The service context specifies a TCS-C of ASCII,
    and a TCS-W of UCS-2.

    The question is, what should the server do with it?

    First of all, there seems to be no way in which the algorithm in
    section 13.2.7.6 can result in the TCS-C specified in the service
    context. So perhaps this bug should be detected and signalled back to
    the sending ORB. How? Using CODESET_INCOMPATIBLE might make sense,
    but that really doesn't flag the bug in the client-side implementation
    of the codesets determination algorithm. Perhaps a straight
    COMM_FAILURE would be better. Opinions?

    Secondly, since this is GIOP 1.0, the client could reasonably ignore
    the service context, and go ahead with using its default codeset
    (Latin-1). However, to do so risks comm failure down the line, as
    ASCII (the TCS-C assumed by the client) does not permit many Latin-1
    characters. It seems better to flag this situation up front.

Version and byte order changes when fragmenting messages (interop)

  • Legacy Issue Number: 3680
  • Status: closed  
  • Source: ICL ( Chris Wood)
  • Summary:

    It's occoured to me that according to the spec it's allowable for
    a message to be fragmented and have second and subsequent
    fragments change the version fields.

    Having the version change while in the middle of reading a
    wstring could cause problems, the CDR encoding of version 1.1
    strings is always two bytes longer than the corresponding 1.2
    encoding, if the version changed while in the middle of reading
    the wstring the length field would be out by two.

    Secondly if request IDs are per-protocol rather than
    per-connection (as aired in issue 3438) then the request ids of
    the fragments could interfere.

    I think an extra phrase should be added to the spec with regards
    to fragmentation, similar to the one regarding byte order:

    The version of fragments must match the version of the initial message that
    the fragment extends.

wchar alignment in GIOP 1.2

  • Legacy Issue Number: 4007
  • Status: closed  
  • Source: Borland Software Corporation ( Vishy Kasar)
  • Summary:

    I have a question on the octet alignment requirement for wchar as
    mentioned in Table 15-1 of CORBA 2.3. In 15.3.1.6 the spec states that

    "For GIOP version 1.2, wchar is encoded as an unsigned binary octet
    value followed by the octet sequence representing the encoded value of
    the wchar. The initial octet contains a count of the number of elements
    in the sequence and the elements of the sequence of octets represent the
    wchar, using the negotiated wide character encoding"

    If this is a variable length octet sequence anyway, specifying an octet
    alignment for this does not make sense. Our assumption is that alignment
    is specified only for GIOP 1.1 style wchars and is irrelevant for
    GIOP 1.2 style wchars. I am looking for confirmation of that assumption.

    If that is a valid assumption, shall we change the table 15.1 third row
    first column entry to state "wchar (in GIOP 1.1)" instead of "wchar"?

    If that is not a valid assumption, what are we aligning here? The length
    byte? The elements of octet sequence? What is the benefit of any
    aligning in this case?

CCM Issue: How are standard EJB exceptions mapped into the CCM View

  • Legacy Issue Number: 3182
  • Status: closed  
  • Source: International Business Machines ( Mr. Ignacio Silva-Lepe)
  • Summary:

    Chapter 8 of the spec specifies mappings between EJB operations and their
    equivalents in the CCM view, but it leaves the mappings of standard EJB
    exceptions unclear.

    Issue:
    Create methods on an EJB home interface all throw the standard
    javax.ejb.CreateException; finder methods on the EJB home interface all
    throw the javax.ejb.FinderException; and remove methods on both home and
    remote interfaces all throw the javax.ejb.RemoveException. In a few cases
    chapter 8 gives an implied mapping: for example, the FinderException on the
    findByPrimaryKey method seems to map to either the
    Components.UnknownKeyValue exception or to the Components.InvalidKey
    exception on the equivalent find_by_primary_key CCM method. Even in these
    cases the names are sometimes inappropriate. In the majority of cases,
    however, there is simply no CCM equivalent to the EJB exception, and bridge
    implementors are left to wonder whether they should attempt a non-standard
    mapping.

    Proposal:
    (a) Add the new CCM standard exceptions Components.CreationFailure,
    Components.NotFound, and Components.RemovalFailure
    (b) Add Components.CreationFailure to the raises clause of all create
    methods on implicit and explicit home interfaces
    (c) Add Components.NotFound to the raises clause of
    find_by_primary_key on implicit home interfaces, and to the raises clause
    of all finder methods on explicit home interfaces
    (d) Add Components.RemovalFailure to the raises clause on the remove
    operation on implicit home interfaces, to the CCMObject.remove operation,
    and to the CCMHome.remove_component operation
    (e) Specify in chapter 8 that the EJB Finder exception is always
    mapped to Components.CreationFailure; that the EJB CreateException is
    always mapped to Components.CreationFailure; and that the EJB
    RemoveException is always mapped to Components.RemovalFailure.
    (f) Make explicit in chapter 8 the already implied mapping bewteen the
    EJB DuplicateKeyException and the Components.DuplicateKeyValue exception

implementing import for C++

  • Source: Progress Software ( Steve Vinoski)
  • Summary:

    I'm concerned that for C++, implementing "import" as currently specified in
    the Components spec will be extremely difficult.

    Imagine how you might implement this: your IDL compiler generates a C++
    header file for all imported name scopes and creates #include directives
    for these files in the C++ code generated for the main IDL file. The main
    problem is that importable name scopes are modules, interfaces, valuetypes,
    structures, unions, and exceptions. To import an exception, for example,
    the import mechanism would have to keep a dependency graph for that
    exception type and make sure that all dependencies are generated into the
    header file so the C++ compilation won't fail. This seems way too complex,
    and I don't see the value of being able to import individual structs and such.

Nested Recursive Structs Legal in 2.3.x?

  • Legacy Issue Number: 3764
  • Status: closed  
  • Source: Perot Systems ( Bill Binko)
  • Summary:

    Given the IDL below, is the third case (labeled "Nested Recursive
    Case") legal in CORBA 2.3.x? (I understand that the answers to my questions
    may change in 2.4: I am interested in possible flaws in 2.3 at the moment).
    If it is legal, I have some concerns listed after the IDL:

    //IDL
    module recurse
    {
    //Recursive Struct: This is legal
    struct TestStruct1

    { sequence<TestStruct1> list; }

    ;
    // Nested Struct: This is legal
    struct TestStruct2 {
    struct TestStruct3

    { long threeMember; }

    twoMember;
    };
    // Nested Recursive Case: IS THIS LEGAL?
    struct One {
    struct Two

    { sequence<One> twoMember; }

    oneMember;
    };
    };

    1) If this IDL is loaded into an IFR, and the type() method of the StructDef
    for ::recurse::One::Two is called, what should happen? I can think of at
    least three interpretations of the spec (in particular, section 10.5) :

    a) type() should fail since the TypeCode for Two is not valid
    outside of the definition of One. If this is the case, what should it
    throw? (the natural result of many implementations would be MARSHAL, but
    that seems wrong)

    b) type() should succeed and should include a complete, valid
    TypeCode of the form:

    //BEGIN TYPECODE//
    Struct_tc(Two)
    MemberList
    StructMember
    twoMember,
    TypeCode: Struct_tc(One)
    MemberList
    StructMember
    oneMember,
    TypeCode: Recursive_tc("IDL:recurse/One/Two:1.0")
    //END TYPECODE//

    c) type() should succeed and should include a complete, valid
    TypeCode of the form:

    //BEGIN TYPECODE//
    Struct_tc(Two)
    MemberList
    StructMember
    twoMember,
    TypeCode: Struct_tc(One)
    MemberList
    StructMember
    oneMember,
    TypeCode: Struct_tc(Two)
    MemberList
    StructMember
    twoMember,
    TypeCode: Recursive_tc("IDL:recurse/One:1.0")
    //END TYPECODE//

    2) Similarly, what should the behavior be when the type() method on the
    generated structs (or their Helper classes in Java) are called? In
    particular, at what point is the ORB responsible for "embedding" the
    recursive TypeCode in its enclosing TypeCode as specified by section 10.7.3
    "Creating TypeCodes"?

    For example, given the following code (in Java, but applied to other
    languages):

    TypeCode recursiveTC = orb.create_recursive_tc("IDL:recurse/One:1.0");

    org.omg.CORBA.StructMember[] members = new
    org.omg.CORBA.StructMember[1];
    members[0] = new org.omg.CORBA.StructMember("twoMember",
    _orb().create_sequence_tc(0, recursiveTC), null);
    /1/ TypeCode twoType = _orb().create_struct_tc(id(), "Two", members);

    members = new org.omg.CORBA.StructMember[1];
    members[0] = new org.omg.CORBA.StructMember("oneMember", twoType,
    null);
    /2/ TypeCode oneType = _orb().create_struct_tc(id(), "One", members);

    If 1 attempted to resolve the recursive TC, it would fail.
    If 2 attempted to resolve the recursive TC, it would succeed, but would
    have to traverse all of twoType's members to see if there was a recursive TC
    in there.

    Any other thoughts on this issue would be appreciated.

incomplete rules for forward declaration of structs/unions

  • Summary:

    1. The phrase "the only recursion permitted for constructed types with the exception of value types" is confusing: a) valuetypes are not constructed types b) the definition of a valuetype may indeed be recursive, but then so can interfaces - why are these not mentioned? Are you trying to say something specific with regard to valuetypes?

    2. The cross reference in the first example should be 3.10.7 not 3.10.3.

    3. Why does the second paragraph on page 3-38 insist that a forward declared definition must follow "in the same source file"? While this is sensible I do not see the point in enforcing it (there is a separate rule about repository IDs which has a bearing). I couldn't find a statement requiring completion of forward interface and valuetype declarations to compare with - I have always assumed these must be satisfied too.

    Interface B has an inherited operation named B. Whether it is legal or

    within interface B.

    This issue is subtly different from the discussions in issue 3525.
    Operations and attributes are more strongly "introduced" into the
    inherited interface than type declarations are, since inherited type
    declarations can be overridden, but operations and attributes cannot.

    I think the IDL specification should be clarified to state whether the

Values for CORBA::ARG_IN,... not defined

  • Legacy Issue Number: 3905
  • Status: closed  
  • Source: Oracle ( Harold Carr)
  • Summary:

    This is a core issue.

    formal/99-10-07 (and orbrev/00-09-01) section 7.1.1 claims
    arg_modes is a bit mask with CORBA::ARG_IN, ... as possible values.
    The values are not defined in that document.

    The values defined in ptc/00-01-08 (IDL to Java mapping)
    section 1.19.4 do not look like bit masks:

    typedef unsigned long Flags;
    const Flags ARG_IN = 1;
    const Flags ARG_OUT = 2;
    const Flags ARG_INOUT = 3;
    const Flags CTX_RESTRICT_SCOPE = 15;

    This needs clarification (e.g., how wide is the bit mask, what
    are the values, or, if not a bit mask, a better definition).

"omg.org" prefix missing from interceptor specification and its reference

  • Legacy Issue Number: 3862
  • Status: closed  
  • Source: Oracle ( Harold Carr)
  • Summary:

    The specification, ptc/00-08-06, defines the following modules:

    Dynamic
    IOP_N
    PortableInterceptor

    These modules reference the following modules:

    CORBA
    IOP
    Messaging

    The CORBA 2.4 specification, orbrev/00-09-01, only explicitly specifies:

    #pragma prefix "omg.org"

    for:

    DynamicAny (page 196)
    CORBA, the Interface Repository Case, (p 280)
    PortableServer (page 338)

    and the Messaging specification, orbos/98-05-05, specifies the prefix
    for messaging.

    ----------

    Proposed solution:

    Either explicitly add

    #pragma prefix "omg.org"

    before Dynamic, IOP_N, PortableInterceptor, CORBA (in general), and IOP

    OR

    Change, the second paragraph of 10.6.7 RepositoryIDs for OMG-Specified Types
    (page 270)

    from:

    "All official OMG IDL files shall contain the following pragma prefix
    directive:

    #pragma prefix "omg.org"

    unless said file already contains a pragma prefix identifying the
    original source of the file (e.g., "w3c.org")."

    to:

    "All official OMG IDL modules shall contain the following pragma prefix
    directive:

    #pragma prefix "omg.org"

    unless said file already contains a pragma prefix identifying the
    original source of the module (e.g., "w3c.org")."

    ----------

    Discussion:

    Perhaps we can interpret 10.6.7 above to mean already mean the all
    official OMG modules have the "omg.org" prefix. In that case, there
    is no issue.

Inheritance description incorrect

  • Key: CORBA24-84
  • Legacy Issue Number: 3525
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    On page 3-46, CORBA 2.3, we have some old words that got forgotten during
    the scope resolution rule cleanup we did some time ago:

    Inheritance produces shadow copies of the inherited identifiers;
    that is, it introduces names into the derived interface, but these
    names are considered to be semantically the same as the original
    definition. Two shadow copies of the same original (as results
    from the diamond shape in Figure 3-1 on page 3-21) introduce a
    single name into the derived interface and don't conflict with
    each other.

    That's wrong because it confuses visibility of an identifier with introduction
    of an identifier (which are different things). I would suggest to reword
    as follows:

    Inheritance produces shadow copies of the inherited identifiers;
    that is, inherited identifiers are visible in derived interfaces.
    Such identifiers are considered to be semantically the same as
    the original definition. Two shadow copies of the same original (as
    results from the diamond shape in Figure 3-1 on page 3-21) do
    not conflict with each other.

    This simply gets rid of the word "introduces", which has the wrong meaning.

    Note that these words have been wrong all along, even before we changed
    the name lookup rules. That's because, if inherited identifiers were
    indeed introduced into the derived interface, the following would be illegal
    (but has in fact never been illegal):

    interface B

    { typedef string S; }

    ;

    interface D : B

    { typedef long S; }

    ;

ORB mediation for servant managers, references for servant managers?

  • Key: CORBA24-83
  • Legacy Issue Number: 3460
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    Two questions:

    1) Are calls to operations on servant managers mediated by the ORB?

    2) Is it legal to export the object reference for a servant manager
    to another process?

    For question 1, the answer would appear to be no. Here is why:

    Page 11-17:

    Inactive state

    When a POA manager is in the inactive state, the associated POAs
    will reject new requests. [...] If the client is co-resident in
    the same process, the ORB could raise the OBJ_ADAPTER system
    exception, with standard minor code 1, to indicate that the
    object implementation is unavailable. [...]

    If the transition into the inactive state is a result of calling
    deactivate with an etherealize_objects parameter of

    • TRUE - the associated POAs will call etherealize for
      each active object associated with the POA once all
      currently executing requests have completed processing
      (if the POAs have the RETAIN and USE_SERVANT_MANAGER
      policies). If a servant manager has been registered for
      the POA, the POA will get rid of the object. If there
      are any queued requests that have not yet started
      executing, they will be treated as if they were new
      requests and rejected.

    If calls to servant managers were to be ORB-mediated, the calls to
    etherealize() cannot possibly be dispatched because the corresponding
    servant manager is already in the inactive state. The only logical conclusion
    I can see is that calls to servant managers are not mediated by the ORB.

    I think the spec should be updated to state this.

    For question 2, the answer would also appear to be no:

    Exporting a reference to a servant manager outside my own address space
    makes no sense whatsoever. Here a servant manager offers either
    incarnate() and etherealize(), or it offers preinvoke() and postinvoke().
    These are the only operations that are possible (apart from operations
    on Object). If it were possible to export a reference to a servant
    manager to another address space, there is nothing the receiver of
    the reference could do with it (other than call operations on Object).
    That's because incarnate(), etherialize(), and preinvoke use a native
    type (servant). postinvoke() doesn't use a native type, but
    accepts a parameter of type POA, so postinvoke cannot be invoked
    remotely either (because POA is locality constrained and its
    reference cannot be marshaled).

    So, it appears clear that export of servant manager references should be
    illegal and flagged the same way as an attempt to export a POA manager
    reference.

    The spec currently says this about servant managers:

    A ServantManager object must be local to the process containing
    the POA objects it is registered with.

    Contrast this with POA managers, for which the spec says:

    A POAManager object must not be exported to other processes,
    or externalized with ORB::object_to_string. If any attempt is
    made to do so, the offending operation will raise a MARSHAL
    system exception. An attempt to use a POAManager object with
    the DII may raise the NO_IMPLEMENT exception.

    To me, it looks like we should say the same thing for servant managers as
    for POA managers.

    And, by the same reasoning, I think it also must be said for the
    AdapterActivator interface: it doesn't make sense to marshal a reference
    for an adapter activator because the only operation (unknown_adapter) has
    an in parameter of type POA, which cannot come from a remote location.

Policy Management in the ORB core

  • Key: CORBA24-92
  • Legacy Issue Number: 3614
  • Status: closed  
  • Source: foxfield-sw.demon.co.uk ( Nick Sharman)
  • Summary:

    (All document refs to ptc/00-03-02, but I think the relvant sections are the
    same in ptc/00-04-05)

    (a) Sec. 4.3.7.1 (Object::get_policy) says that the "effective Policy is the
    intersection of the values allowed by the effective override and the
    IOR-specified Policy." What does this mean? For example, the example
    MyPolicy given in 4.8.5 appears to define some range or interval, so the
    intersection of two MyPolicy objects has some meaning - but I doubt if it's
    reasonable to expect the ORB to deduce that.

    I suggest that the effective policy is:

    • any override of that type if there is one, else
    • any IOR-specified policy of that type if there is one, else
    • the system default of that type if there is one, else
    • the null Policy reference (or a system exception? which?).

    This is feasible and consistent with normal meaning of "override" as
    "replace", not "modify".

    (b) Sec. 4.3.7.2 (Object::get_client_policy) suggests that the ORB searches
    the object's overrides, then PolicyCurrent's overrides, then PolicyManager's
    overrides. If it can't find any in those, then it can return the system
    default. I suggest the system default be left out of this search - it's not
    an override, it's a final default - and that we define what happens if no
    policy of the right type can be found, either null or a system exception.

    (c) Sec. 4.3.8.1 (Object::set_policy_overrides) and sec. 4.9.3.1
    (PolicyManager::set_policy_overrides) both allow the existing set of
    overrides either to be replaced or to be extended.

    If the set is to be extended, and the new overrides contain a Policy of a
    type for which there is already an override, should the supplied Policy
    (1) replace the existing Policy silently, or
    (2) be ignored silently, or
    (3) cause a system exception (and which)?

    Whatever the value of 'set_add', if the supplied Policy list contains two
    Policies of the same type, which one prevails, if any? I suggest
    "implementation defined", but we could mandate a system exception.

    Another is using quotation mark.
    Is the rule adapted in IDL preprocessor?
    Could you send me a document about Preprocessing rule?

    Another question is #ifdef, #ifndef.
    Is this option able to be duplicated?

    Last question is about position of inclusion command.
    In some example in specification 2.3, I find this example.

ORB shutdown vs destroy

  • Key: CORBA24-90
  • Legacy Issue Number: 3608
  • Status: closed  
  • Source: Borland Software Corporation ( Vishy Kasar)
  • Summary:

    CORBA2.3.1 section 4.11.5 destroy() has following information.

    Once an ORB is destroyed, another call to ORB_init with same ORBid will
    return a reference to a newly constructed ORB.

    My assumption here is if I call shutdown() on an ORB followed by
    ORB_init() with the same ORBid as of the shutdown ORB, I get the same
    ORB back. Essentially, we can not get rid of that ORB until destroy() is
    called. Is this a valid assumption? If so, can we add a sentence to that
    effect to shutdown() section?

description of unknown_adapter

  • Legacy Issue Number: 3740
  • Status: closed  
  • Source: Oracle ( Anita Jindal)
  • Summary:

    2. According to CORBA V2.3 spec, 99-10-07.pdf, section 11.3.3.2
    description of unknown_adapter, indicates that:
    " The implementation of this operation should either create the specified
    POA and return TRUE, or it should return FALSE. If the operation returns TRUE,
    the ORB will proceed with processing the request. If the operation returns
    FALSE,
    the ORB will return OBJECT_NOT_EXIST to the client."

    In Section 11.3.8.3, find_POA specifies the following:

    "If a child POA with the specified name does not exist and the value of
    the activate_it parameter is TRUE, the target POA's AdapterActivator,
    if one exists, is invoked, and, if it successfully activates the child POA,
    that child POA is returned. Otherwise, the AdapterNonExistent exception is
    raised."

    Since find_POA itself invokes the unknown_adapter() method on the
    AdapterActivator.
    If the unknow_adapter() returns false, the find_poa() should throw an
    OBJECT_NOT_EXIST exception. This is not very clear from explanation in
    section 11.3.8.3.

Missing exception for activation

    For explicit activation, the spec says:

    11.3.8.15 activate_object

    ObjectId activate_object(in Servant p_servant)
    raises (ServantAlreadyActive, WrongPolicy);

    This operation requires the SYSTEM_ID and RETAIN policy; if not
    present, the WrongPolicy exception is raised.

    And:

    void activate_object_with_id(

    raises (ObjectAlreadyActive, ServantAlreadyActive, WrongPolicy);

    This operation requires the RETAIN policy; if not present, the
    WrongPolicy exception is raised.

    Neither section says that IMPLICT_ACTIVATION would be required.

    The intent for IMPLICIT_ACTIVATION was that it permits implicit activation
    as well as explicit activation. However, I can infer this only by reading
    between the lines. In particular, in section 11.2.7, the intent is never
    made clear.

    I would suggest to change the the text in section 11.2.7 from:

AbstractBase not declared.

  • Source: Département Informatique & Réseaux ( Thomas Quinot)
  • Summary:

    The standard IDL files included in the corba/ subdirectory
    of the IDL text files archive, formal/00-04-01, should be compilable
    with any compliant IDL parser. Most notably, these files comprise
    a "corba/orb.idl" source file, whose inclusion in application
    IDL files is necessary whenever an application has to manipulate
    type CORBA::TypeCode (as mandated by section "3.14 CORBA module"
    of the CORBA specification v. 2.3).

    It is thus expected that the file corba/orb.idl be a legal
    IDL specification.

    This is not the case, because the corba/orb.idl files #includes
    a CORBA_Stream.idl file, which contains the following declaration:

    abstract valuetype DataOutputStream

    { [...] void write_Abstract (in AbstractBase value); [...] }

    In this declaration, the syntax of the language imposes that
    the name AbstractBase be interpreted as a <scoped_name>.
    This <scoped_name> is not defined in corba/orb.idl or any of
    the files it #includes.
    The declaration is therefore illegal.

    According to the CORBA 2.3 specification, section
    "4.2 The ORB operations", module CORBA contains a declaration
    "native AbstractBase".

    The following resolution is therefore proposed for this issue:

    In file corba/orb.idl, include the followinf declaration:

    deactivate_object was called. In this case, POA continues to service
    those requests and throws OBJECT_NOT_EXIST for future requests if the
    object is not activable.

    2. Active requests are any requests. In this case, POA will continue
    to service requests that come even after deactivate_object was called
    as long as deactivation is not complete.

    So what is the intended interpretation? I suspect it is 1. If so, can we

    make this section clearly state that?

how are valid ORBids determined

  • Legacy Issue Number: 3443
  • Status: closed  
  • Source: Cisco Systems ( Paul Kyzivat)
  • Summary:

    Section 4.5.1 of the CORBA core document explains the ORBid argument to
    ORBinit. However, it is sufficiently vague to present implementation and
    usage problems.

    It says:

    "All ORBid strings other than the empty string are allocated
    by ORB administrators and are not managed by the OMG."

    It fails to define ORB administrator. This administrator could be the
    developer of the application calling the ORB, or it could be the
    administrator of the machine on which the ORB will run, or it could be the
    developer of the ORB itself. Each answer to this question may result in a
    different mechanism for determining if a supplied ORBid is valid.

POA namespace and ORB ID

  • Status: closed  
  • Source: Oracle ( Ken Cavanaugh)
  • Summary:

    Section 4.6 of CORBA 2.3.1 addresses the meaning of the ORBid argument. It is clear
    that ORB_init can be called multiple times in the same address space resulting in
    different ORBs. I think the CORBA spec should make it clear that all of these ORBs
    have different POA namespaces. This should probably be indicated in section 11.2.3
    by stating something like:

    If an application makes use of multiple ORBs in the same address space, each
    ORB defines its own separate POA namespace. In particular, each ORB returns a
    distinct root POA in response to a resolve_initial_references( "RootPOA" )
    call.

servant_to_id versus servant_to_reference

  • Key: CORBA24-94
  • Legacy Issue Number: 3636
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    This operation requires the USE_DEFAULT_SERVANT policy or a
    combination of the RETAIN policy and either the UNIQUE_ID or
    IMPLICIT_ACTIVATION policies; if not present, the WrongPolicy
    exception is raised.

    Note that there is nothing conditional here. If these policies are not
    present, the operation raises an exception.

    Compare this with servant_to_reference:

    This operation requires the RETAIN policy and either the
    UNIQUE_ID or IMPLICIT_ACTIVATION policies if invoked outside
    the context of an operation dispatched by this POA.

    Note that, in this case, we have a qualification:

    "... if invoked outside the context of an operation..."

    Why the difference between the two? They almost do the same thing, namely,
    map from a servant to an object ID. It's just that servant_to_reference,
    after it has the object ID, also embeds that object ID in a reference.

    So, shouldn't the two operations behave the same way? In particular,
    why should servant_to_id raise an exception if I call it from within the
    context of an executing operation on the specified servant?

    In other words, it seems that the behavior specified for servant_to_reference
    is correct and should apply equally to servant_to_id. In effect, calling
    the operation from withing an executing operation on the specified servant
    should do the same thing as calling get_object_id on the POA Current and
    use the resulting id.

    Am I missing something?

ORB::shutdown underspecified

  • Key: CORBA24-93
  • Legacy Issue Number: 3618
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    If I call ORB::shutdown(), it implicitly calls POA::destroy() on the
    Root POA.

    I assume that the value of the wait_for_completion parameter to
    ORB::shutdown() should be passed through to POA::destroy()? The spec isn't
    entirely clear on this point.

    Further, what is the effect of calling ORB::shutdown() on the value
    of the etherealize_objects parameter for POA::destroy()? Since ORB::shutdown()
    doesn't have an etherealize_objects parameter itself, the value passed
    through to POA::destroy must be implicit, but the spec doesn't say what
    it is.

    Similarly, ORB::destroy() implicitly calls ORB::shutdown(). From the
    second-last para on page 4-35, it would appear that this implicit call
    is made as ORB::shutdown(true) rather than ORB::shutdown(false). It
    might be nice to make this explicit so I don't have to read between the
    lines to figure it out.

Incorrect use of negative fixed scale

  • Key: CORBA24-87

  • Source: Cisco Systems ( Paul Kyzivat)
  • Summary:

    In section 3.9.2 (of ptc/99-12-07) on semantics of constants,
    an example is given showing 3000.00D being of type fixed<1,-3>.
    This is inconsistent with statements elsewhere that fixed scale is a
    non-negative quantity.

    Also, the preceding explanation states: "... leading and trailing zeros are
    factored out, INCLUDING NON-SIGNIFICANT ZEROS BEFORE THE DECIMAL POINT."
    This rule of course leads to negative scale factors, so it must also be
    incorrect.

    Suggested Revision:

    Change the following text:

    "A fixed-point literal has the apparent number of total and fractional
    digits, except leading and trailing zeros are factored out, including
    non-significant zeros before the decimal point. For example, 0123.450d is
    considered to be fixed<5,2> and 3000.00d is fixed<3,-1>."

    to:

    "A fixed-point literal has the apparent number of total and fractional

is_equivalent and policies

  • Summary:

    How should is_equivalent() behave if I compare two references that denote
    the same object at the same location, using the same profiles, etc, but
    differ in the policies? Do differences in the policies affect the outcome?

    My gut feeling is that is_equivalent() should return false in this case
    because it uses reference identity, not object identity. However, we
    are rapidly approaching the point where is_equivalent() might as well
    unconditionally return false because we are adding more and more flavours
    of additional information into IORs as time goes by. Invocation policies,
    transaction policies, codesets, multiple profiles, optional components,
    etc, etc.

    Does is_equivalent() require a more precise definition in order to remain
    useful?

POA servant_to_id inconsistent with servant_to_reference

  • Key: CORBA24-89
  • Legacy Issue Number: 3607
  • Status: closed  
  • Source: Humboldt-Universitaet ( Martin von Loewis)
  • Summary:

    In CORBA 2.3, servant_to_id does not work if the POA has the RETAIN,
    MULTIPLE_ID, and NO_IMPLICIT_ACTIVATION policies, even if
    servant_to_id is invoked in the context of the specified servant.
    According to 11.3.8.20, such a call raises WrongPolicy.

    Inconsistent with that specification, it is apparently still possible
    to obtain the ID for that servant, using

    id = poa.reference_to_id(poa.servant_to_reference(self))

    This works since 11.3.8.21/3 supports all cases of currently-active

Valuetypes with multiple interfaces

  • Key: CORBA24-88
  • Legacy Issue Number: 3589
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    consider the following, which as valid IDL as best as I can figure out:

    interface I1 {};
    abstract valuetype V1 supports I1 {};

    interface I2 {};
    abstract valuetype V2 supports I2 {};

    interface I3 {};
    valuetype V3 : V1, V2 supports I3 {};

    The above raises some very interesting issues. For one, this can't be
    mapped into C++ for a number of reasons (largely having to do with
    ambiguous multiple inheritance). However, there much deeper issues here
    relating to the object model. Some questions:

    • What is the type of the a V3 instance?
    • What is the repository ID of that instance?
    • What is the return value of a call to _this()?
    • What is the result of invoking

    is_a("IDL:I1");
    is_a("IDL:I2");
    is_a("IDL:I3");

    on an I3 reference?

    • What are the results of I1::narrow(), I2::narrow(), and I3::narrow()
      on an I3 reference?
    • What is returned by a call to get_interface()?
    • What are the results of traversing the above in an IFR?

    There are probably more questions along these lines. They all aim at
    the fact that the above construct effectively creates an object that has
    multiple unrelated interfaces. This flies in the face of the CORBA
    type system, which fundamentally requires every object to have exactly
    one most-derived type.

    I think we need to put the axe through constructs such as the one above
    in a hurry!

Non-escaped keywords in published IDL

  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    I know that this is probably not the best RTF to send this to, but the
    issue spans RTFs and we don't have RTFs for the collection or the life cycle
    service, so I'm sending this to the Core RTF for want of a better task force...

    In the CosLifeCycle IDL (formal/98-10-01.idl), we have:

    module CosLifeCycle{

    typedef CosNaming::Name Key;
    typedef Object Factory;
    typedef sequence <Factory> Factories;

    The two occurences of "Factory" are illegal. According to the comment
    at the beginning of the module, this should read:

    module CosLifeCycle{

    typedef CosNaming::Name Key;
    #ifdef NO_ESCAPED_IDENTIFIERS
    typedef Object Factory;
    typedef sequence <Factory> Factories;
    #else
    typedef Object _Factory;
    typedef sequence <_Factory> Factories;
    #endif

    The same problem also appears in formal/98-10-15.idl.

    Also in formal/98-10-01.idl:

    // C o l l e c t i o n F a c t o r i e s
    interface CollectionFactories : CollectionFactory {
    boolean add_factory (
    in Istring collection_interface,
    in Istring impl_category,
    in Istring impl_interface,
    in CollectionFactory factory);

    // ...

    // R A C o l l e c t i o n F a c t o r i e s
    interface RACollectionFactories : RACollectionFactory {
    boolean add_factory (
    in Istring collection_interface,
    in Istring impl_category,
    in Istring impl_interface,
    in RACollectionFactory factory);

    Both operation definitions need the same #ifdef to map away from the
    "factory" keyword that is used as a parameter name.

    That same problem also appears in formal/98-10-03.idl.

    I guess the IDL in the formal CORBAservices documents should be fixed too.

POA status during destruction is unclear

  • Legacy Issue Number: 3436
  • Status: closed  
  • Source: Cisco Systems ( Paul Kyzivat)
  • Summary:

    The description of POA destroy in section 11.3.8.4 is unclear.
    There are several ways to implement this, which may result in problems
    porting application code between orbs.

    Some of the ambiguities are:

    1) It may or may not be legal for an application to create new child POAs
    while the existing children are being destroyed. This could happen
    explicitly or via AdapterActivators. Such behavior could prevent destruction
    from ever completing.

    2) If the POA's POAManager is in the holding state at the time of
    destruction (or if its state is changed to holding during the destruction
    process), it isn't clear what happens to the held requests.

    3) If the POA's POAManager is active, what happens to requests that arrive
    after the call to destroy but before the destruction becomes apparent? If
    they are to be serviced, a sufficiently rapid arrival rate may prevent the
    destruction from ever completing.

Problem with valuetype parameter copying

  • Key: CORBA24-77
  • Legacy Issue Number: 3364
  • Status: closed  
  • Source: Floorboard Software ( Jonathan Biggar)
  • Summary:

    Corba 2.3.1 section 5.2.4.3 states that valuetypes passed as parameters
    are copied when passed into the receiving context. Is this also true
    for valuetypes that are embedded in a contructed IDL type passed as a
    parameter?

    Example:

    // IDL

    valuetype V { };

    struct S

    { V a_v; }

    ;

    interface I

    { S op(in S s1, inout S s2, out S s3); }

    ;

    When I::op is called are the valuetypes embedded in s1, s2, s3 and the
    return value supposed to be copied when making a collocated call?

    Example 2:

    // IDL

    interface J

    { any op(in any a1, inout any a2, out any a3); }

    ;

    If one of the any parameters to J::op contains a valuetype, must it be
    copied before/after a collocated call? What if the any contains a
    struct S instead?

    It seems to me we need to revisit the valuetype copying issue. We have
    three choices:

    1. Valuetypes are not copied for collocated calls.
    2. Only valuetypes as explicit parameters are copied for collocated
    calls.
    3. All valuetypes are copied no matter how deeply they are nested in
    parameters.

    Currently the specification is ambiguous as to whether the semantics are
    supposed to be case 2 or 3. Case 3 is the only one that provides
    guaranteed location transparency, but the cost to implement case 3 for
    collocated calls far too high. It would effectively require the same
    overhead as marshalling/unmarshalling for any operation that has a
    valuetype embedded in a complex IDL type or any.

    So, given that transparency for collocated calls cannot be maintained
    without high overhead, should we completely remove the copying
    requirement because transparency cannot be maintained, or should we just
    document that case 2 is the accepted semantic?

    • Is it legal to call poll_response more than once?

    I think that, for the first three, we should raise BAD_INV_ORDER. We
    also need minor codes for those.

    For case four, I'd suggest that calling poll_response multiple times is OK,
    but that calling it once get_response was called should raise BAD_INV_ORDER.

Efficient construction of Any types w/o DynamicAny

    I'm thinking of a dynamic DII gateway that needs to shovel large

    must employ the DynAny type, and loop over the number of elements,
    calling insert_octet() or get_octet() repeatedly. This is inefficient,
    especially for large sequences/arrays of basic types.

    I think that a more efficient mechanism might be useful for some

  • Source: BROKAT Informationssysteme ( Blake Biesecker)
  • Summary:

    In order to resolve the OTS RTF issue 1819, we need
    to have clearer wording regarding what COMPLETED_NO.

    Since we now have the POA, the following phrase from
    section 3.17 is not clear enough:

    COMPLETED_NO The object implementation was never initiated prior to the exception being raised

    In order to get proper rollback logic for transactions
    that get system exceptions and, I'd imagine, to get
    proper fault tolerant behavior, it needs to be made
    clear that COMPLETED_NO means that absolutely no execution
    on the server took place prior to the exception being
    raised. Without such a clarification, it is not possible
    to guarantee data integrity for fault tolerance and it
    forces the OTS to insist on a strict rollback policy when
    a system exception is raised.

    In particular, with the advent of the POA, "object implementation"
    is not as clear as it once was. Does this include servant
    locators, for example.

    As a place to start, I'd like to suggest this instead:

    COMPLETED_NO No execution was initiated in the server prior to the exception being raised

    (The archive for issue 1819 contains a lot more
    discussion on this topic as it relates to the

    and unions) must have the same prefix in effect wherever they appear.

    construct result in a compile-time diagnostic. For example:

Can native be used in constructed IDL types?

  • Key: CORBA24-69
  • Legacy Issue Number: 3258
  • Status: closed  
  • Source: Floorboard Software ( Jonathan Biggar)
  • Summary:

    CORBA 2.3.1, section 3.10.5 says:

    "A native type may be used to define operation parameters and results.
    However, there is no requirement that values of the type be permitted in
    remote invocations, either directly or as a component of a constructed
    type."

    This is ambiguous as to whether a native type may be used in a
    constructed IDL type that is intended to be used only locally:

    // IDL

    native MyNative;

    struct MyStruct

    { MyNative a_native; }

    ;

    So, should the first sentence in 3.10.5 be read to mean that native may
    ONLY be used in parameters & results? If so, we ought to put the word
    "only" in there.

response_flags in interop draft

  • Key: CORBA24-76
  • Legacy Issue Number: 3338
  • Status: closed  
  • Source: UBS ( Hans Kneubuehl)
  • Summary:

    n the interop draft (ptc/00-02-04) the response_flags are defined now in terms
    of SyncScope. However, SyncScope does only apply to oneway, DII with
    INV_NO_RESPONSE, and sendc-stubs with no reply handler. The Messaging
    submission explicitly defines that it is ignored in the other cases.

    from CORBA Messaging:

    interface SyncScopePolicy

    This interface is a local object derived from CORBA::Policy. It is applied to
    oneway
    operations to indicate the synchronization scope with respect to the target of
    that
    operation request. It is ignored when any non-oneway operation is invoked. This
    policy is also applied when the DII is used with a flag of INV_NO_RESPONSE since
    the implementation of the DII is not required to consult an interface
    definition to
    determine if an operation is declared oneway. The default value of this Policy
    is not
    defined. Applications must explicitly set an ORB-level SyncScopePolicy to ensure
    portability across ORB implementations. When instances of SyncScopePolicy are
    created, a value of type Messaging::SyncScope is passed to
    CORBA::ORB::create_policy. This policy is only applicable as a client-side
    override. The client’s SyncScopePolicy is propagated within a request in the
    RequestHeader’s response_flags as described in GIOP Request Header.

Inheritence table 3-10 wrong?

  • Key: CORBA24-66
  • Legacy Issue Number: 3203
  • Status: closed  
  • Source: Floorboard Software ( Jonathan Biggar)
  • Summary:

    There appears to be a minor glitch in table 3-10. It states that
    stateful valuetypes can only support one non-abstract interface, but it
    is not clear what is correct for abstract valuetypes or abstract
    interfaces, since it uses the words "supports", not "supports single" or
    "multiple" which are used elsewhere. It certainly does not appear
    reasonable for abstract valuetypes to be able to inherit from more than
    one non-abstract interface when stateful valuetypes cannot.

    This brings up a question: Can abstract valuetypes support non-abstract
    interfaces? It's not clear to me what the answer to this ought to be.

    Anyway, it appears to me that part of the table should look like this
    instead:

    May inherit from: | Interface | Abstract Interface
    ---------------------------------------------------------------------------
    Abstract | *no or supports single| multiple
    Value |

#pragma rules are too restrictive

  • Key: CORBA24-71
  • Legacy Issue Number: 3269
  • Status: closed  
  • Source: Triodia Technologies Pty Ltd ( Michi Henning)
  • Summary:

    I think the current rules for #pragma are too tight and we need to relax
    them. In particular, for the ID pragma (page 10-43):

    If an attempt is made to assign a repository ID to the same
    IDL construct a second time, a compile-time diagnostic shall
    be emitted, regardless of whether the second ID is in conflict or not:

    interface A {};
    #pragma ID A "IDL:A:1.1"
    #pragma ID A "IDL:X:1.1" // Compile-time error

    interface B {};
    #pragma ID B "IDL:BB:1.1"
    #pragma ID B "IDL:BB:1.1" // Compile-time error

    This causes problems with separate compilation. For example:

    // x.idl
    namespace Foo

    { // ... };
    #pragma ID Foo "IDL:blah:1.0"

    // y.idl
    namespace Foo { // ... }

    ;
    #pragma ID Foo "IDL:blah:1.0"

    // z.idl
    #include "x.idl"
    #include "y.idl"

    The same problem arises with the version pragma, because I may want to
    change the version in two different source files.

    The resolution to issue 3048 special-cases TypeCode in a manner that

    the CORBA module, and thus is properly named CORBA::TypeCode, this is
    highly irregular because it means we have a scoped keyword. Second, this
    change also significantly breaks working products – it adopts
    implementation details of certain compilers and rules out already-working
    implementation approaches of other existing compilers. The OMG is not
    supposed to dictate implementation. Finally, the rationale for the changes
    made for 3048 centered around unquantifiable performance issues that IMO
    affect only a very small minority of applications.

Non-standard system exceptions

  • Key: CORBA24-50
  • Legacy Issue Number: 3104
  • Status: closed  
  • Source: hursley.ibm.com ( Simon Nash)
  • Summary:

    Section 3.17.1 says that "ORB implementations may raise non-standard system
    exceptions." This raises a number of questions:

    1. How are non-standard system exceptions defined? Are they defined using
    IDL, or are they PIDL? If they are IDL, how are they identified as
    system exceptions by the language mappings?

    2. The definitions in section 3.17.1 for standard system exceptions appear
    to be IDL, but I believe the intention is that they are PIDL. This
    should be stated clearly.

    3. Should non-standard system exceptions be defined in the CORBA module like
    the standard system exceptions? There are three choices:
    a. They must be in the CORBA module.
    b. They must not be in the CORBA nmodule.
    c. They can either be in the CORBA nodule or in other modules.

    4. Point 3 raises the more general question of whether it is legal for ORB
    vendors to add non-standard definitions to the CORBA module. Section 3.14
    says that "Names defined by the CORBA specification are in a module named
    CORBA," but it does not say whether these are the only names that may appear
    in the module named CORBA. This should be clarified.

Use of Principal in GIOP Module erroneous

  • Key: CORBA24-49
  • Legacy Issue Number: 3095
  • Status: closed  
  • Source: Thematix Partners LLC ( Jishnu Mukerji [X] (Inactive))
  • Summary:

    In spite of objections based on misunderstandings from certain quarters
    I would like to propose that Principal in the IDL describing GIOP as
    excerpted below be replaced by "sequence <octet>". For whatever it might
    be worth, doing so would make the IDL in the GIOP module actually
    compilable for the first time in its entire existence!

    module GIOP { // IDL extended for version 1.1 and 1.2
    // GIOP 1.0
    struct RequestHeader_1_0

    { // Renamed from RequestHeader IOP::ServiceContextList service_context; unsigned long request_id; boolean response_expected; sequence <octet> object_key; string operation; Principal requesting_principal; ^^^^^^^^^ }

    ;

    // GIOP 1.1
    struct RequestHeader_1_1

    { IOP::ServiceContextList service_context; unsigned long request_id; boolean response_expected; octet reserved[3]; // Added in GIOP 1.1 sequence <octet> object_key; string operation; Principal requesting_principal; ^^^^^^^^^ }

    ;

    ...
    };

    Firstly, ever since the GIOP standard was adopted, the use of Principal
    in that struct has been erroneous, since it is undefined in GIOP module,
    unless adorned with a CORBA:: prefix. Secondly, in effect all that it is
    trying to say
    is that the Principal is represented as a sequence<octet> in the header
    field
    requesting_principal, not a Principal pseudo-interface, which is
    undefined in that context anyway. Thirdly, even if you could find a
    definition for an unadorned Principal somewhere, what is the meaning of
    that type when CDR encoded? It really is
    nothing but sequence<octet>.

    I think this issue should go to the Interop RTF.

  • Summary:

    The current spec for local interfaces disallows making calls to a local

    for implementors of scripting languages. That's because, for a scripting
    language, everything is a DII request. Local interfaces, therefore, force
    the implementor to wrap all pseudo-objects and local interfaces in
    special wrapper objects.

    For pseudo-objects, there is nothing we can do. However, for local
    interfaces, we could require DII calls to be supported.

    Chapter 5.2.5: Value type semantics should not define that an instance of a

    mappings (e.g. C++) because it contradicts the kind and nature of value types.

    A value type instance IS NOT an object reference even if it is registered with
    the ORB. Therefore, if a construct conceptually is not a subtype of another
    construct, it should not be possible that it substitutes the other. Also, it
    should not be required that there are any shortcuts which automatically convert

    99-07-07.pdf, Chapter 3, "OMG IDL Syntax and Semantics", pages 3-37..3-39,
    definition of "sequence" type:

    There is no explicit definition what length sequence may have at run
    time. Things are perfectly defined for sequence bounds (i.e. maximum
    size at compile time) which is explicitly declared to be a positive
    integer. However, nothing is said whether length of sequence at run
    time can be: (a) positive; or (b) non-negative; or even (c) negative.

TypeCode issue

  • Key: CORBA24-45
  • Legacy Issue Number: 3048
  • Status: closed  
  • Source: ZeroC ( Marc Laukien)
  • Summary:

    At present, the following IDL code is illegal:

    interface I

    { CORBA::TypeCode get_type(); }

    ;

    To make it legal, "orb.idl" must be included. From the spec:

    "The file orb.idl contains the IDL definitions for the CORBA module. The
    file orb.idl must be included in IDL files that use names defined in the
    CORBA module."

    I don't think that this is a good idea, because of the following
    reasons:

    • TypeCode is PIDL, not IDL. So orb.idl can only be used as a "switch"
      to enable TypeCode, but it cannot contain a "real" IDL definition for
      TypeCode.
    • Having to include orb.idl for every little program that requires
      TypeCode means a huge overhead, as orb.idl includes everything from
      the CORBA module (including the IFR!).

    I don't see any reason why TypeCode should only be available if orb.idl
    is included. To me, TypeCode is "built-in", even if it doesn't have a
    keyword. So it appears rather strange to me that I have to artificially
    disable TypeCode in our IDL parser if orb.idl is not included, just to
    be compliant with the spec.

    I would therefore propose to allow CORBA::TypeCode in IDL even if
    orb.idl is not included.

IDL scoping rules

    On the other hand, if module Inner2 were:

    module Inner2

    { typedef Inner1::S1 S2; // Inner1 introduced typedef string inner1; // Error typedef string S1; // OK }

    ;

    The definition of inner1 is now an error because the identifier
    Inner1 referring to the module Inner1 has been introduced in the
    scope of module Inner2 in the first line of the module declaration.
    Also, the declaration of S1 in the last line is OK since the
    identifier S1 was not introduced into the scope by the use of
    Inner1::S1 in the first line.

    This is fine, but it doesn't make it clear that, if the name is qualified,
    it is not introduced into the scope.

    handle a TypeCode argument that has a TCKind of either tk_null or tk_void.

    I assume these are valid argument TypeCodes that do not result in an
    InconsistentTypeCode exception, and the returned DynAny is simply one that
    fulfills the basic DynAny interface and has no components. However, it
    would be nice to explicitly document the cases for these two TypeCodes,
    though, given that they're a little different from other TypeCodes in that
    they can't have any associated values.

IDL and C++ relationship

PIDL vs Local

  • Key: CORBA24-33
  • Legacy Issue Number: 2974
  • Status: closed  
  • Source: Fujitsu ( Tom Rutt)
  • Summary:

    Regarding using a version in a repository ID:

    If old PIDL were to be recast to local, each time the
    interface def would be enhanced (by adding new local
    operations), the IDL module would have to be appropriately
    versioned.

    I also point out that using a version for corba::object's repository
    id seems inappropriate, since there are multiple version of
    corba::object which the omg never bothered to version, since they
    did not have to.

    Thus, in summary, putting version 1.0 to correspond to a pidl interface
    implies stability in that inteface (i.e., it will not change without
    changing
    the version number), which the OMG has never enforced for PIDL.

URLs interact poorly with code set selection

  • Legacy Issue Number: 2900
  • Status: closed  
  • Source: Cisco Systems ( Paul Kyzivat)
  • Summary:

    The corbaname & corbaloc url formats provide a situation where an IOR
    designating a server is created and used by a client without input by
    that server.

    One (optional) element of an IOR is a CodeSetComponent specifying the
    code sets that the server is willing/able to utilize. Normally these are
    examined by a client and used to select a pair of code sets (narrow and
    wide) to be used for communication between client and server.

    Chapter 13 of the Corba spec states: "If the code set component is not
    present in a multi-component profile structure, then the deault char
    code set is ISO 8859-1 for backward compatibility. However, there is no
    default wchar code set. If a server supports interfaces that use wide
    character data but does not specify the wchar code sets that it
    supports, client-side ORBs will raise exception INV_OBJREF."

    This seems to imply one of the following:
    1) URLs may not be used to reference interfaces that employ wide
    characters;
    2) URLs must generate IORs with a code set component supporting
    wchar data;
    3) The CORE must be changed to relax the above restrictio

Wchar as discriminator in union

  • Key: CORBA24-10
  • Legacy Issue Number: 2859
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: Just got a question from our IDL compiler folks - I think they"ve
    found a bug in the 2.3 IDL chapter..... (actually the bug has been there
    for a while)..

    Looking at the new CORBA2.3 book,

    The syntax for discriminated unions are described on two pages (3-16 and
    3-36).
    On both pages the <wchar_type> isn"t included in the grammar for
    <switch_type_spec>. Therefore my conclusion was that it shouldn"t be
    allowed. The problem is that further down on page 3-36 there is a table
    for "case label matching" and in that table wchar is listed as a

Problem with text of POAManager::deactivate()

  • Key: CORBA24-23
  • Legacy Issue Number: 2911
  • Status: closed  
  • Source: Floorboard Software ( Jonathan Biggar)
  • Summary:

    The first paragraph of 11.3.2.6 says:

    This operation changes the state of the POA manager to inactive. If
    issued while the POA manager is in the inactive state, the
    AdapterInactive exception is raised. Entering the inactive state causes
    the associated POAs to reject requests that have not begun to be
    executed as well as any new requests.

    But the last paragraph says:

    If deactivate is called multiple times before destruction is complete
    (because there are active requests), the etherealize_objects parameter
    applies only to the first call of deactivate; subsequent calls with
    conflicting etherealize_objects settings will use the value of the
    etherealize_objects from the first call. The wait_for_completion
    parameter will be handled as defined above for each individual call
    (some callers may choose to block, while others may not).

    So which is right? Is does a subsequent call to deactivate() raise
    AdapterInactive, or does it succeed, perhaps blocking until completion?

creation of arguments to TypeCode creation ops

  • Key: CORBA24-19
  • Legacy Issue Number: 2907
  • Status: closed  
  • Source: DSTC ( Stephen Crawley)
  • Summary:

    It is not clear from section 10.7.3 of CORBA 2.3 how much param checking
    the ORB operations for TypeCode creation should do. It is also unclear
    whether only the BAD_PARAM exception should be raised, or whether some
    others are legitimate; e.g. BAD_TYPECODE.

    Here are some detailed questions on TypeCode creation argument checking:

    1) should the operations that take a "name" argument check that it
    is a valid IDL name? A non null string?

    2) should the operations that take a "RepositoryId" argument check
    that it has a recognisable format?

    3) should the operations that take content and member types as
    parameters check that they are legitimate; i.e. that they
    don't have kinds tk_null, tk_void or tk_exception.

    4) should the operations that take members check that the member
    names are valid IDL names and that they are unique within the
    member list?

    5) should create_union_tc check that there are no duplicate label
    values? Should it check that the labels' TypeCodes are equal to
    discriminator TypeCode? Or equivalent?

    6) should create_union_tc check that the supplied discriminator
    type is legitimate?

    There are probably more cases as well.

DynFixed editorial issue

  • Key: CORBA24-18
  • Legacy Issue Number: 2906
  • Status: closed  
  • Source: Progress Software ( Steve Vinoski)
  • Summary:

    In the CORBA 2.3 spec for DynFixed::set_value (page 9-14) it says, "If val
    contains a value whose scale exceeds that of the DynFixed or is not
    initialized, the operation raises InvalidValue."

    Later in the same paragraph it says, "If val has more fractional digits
    than can be represented in the DynFixed, fractional digits are truncated
    and the return value is false."

    Given that the term "scale" is used with the fixed-point type to describe
    the number of fractional digits, these two quoted sentences are confusing
    and appear to contradict one another.

    I propose changing the first quoted sentence to: "If val contains a value
    whose number of digits exceeds the maximum number of digits specified by
    the TypeCode of the DynFixed, or if val is not initialized, the operation
    raises InvalidValue."

mixing giop versions

  • Key: CORBA24-3
  • Legacy Issue Number: 2822
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: The spec is currently unclear on when and how messages with different
    giop versions may share a single connection.

    This has already been discussed, with different RTF members holding
    positions running the range from: "all messages on a connection must
    have the same giop version" to "messages with differing giop versions
    must be permitted on the same connection". So clearly there is an issue.

    The resolution of this issue should address at least the following
    unclear points:

    1) suppose a client orb supporting giop 1.2 initiates an invocation on
    an IOR with iiop version 1.1. As a result, it establishes a new
    connection and sends the request using giop 1.1. Later, the same client
    obtains another IOR referencing the same transport address, but
    specifying iiop version 1.0.

    • may the same connection be used to send a request to the new IOR?
    • if so, what giop version should be used to send the request?

    2) Later, the same client obtains another IOR referencing the same
    transport address, but specifying iiop version 1.2.

    • may the same connection be used to send a request to the new IOR?
    • if so, what giop version should be used to send the request
    • if so, what giop version should be used to send subsequent requests
      to the IORs mentioned in (1).

    3) Imagine a day in the not too distant future, when giop 1.3 has been
    approved and implemented. A client that supports giop 1.3 obtains an IOR
    with iiop version 1.2, establishes a new connection, and then sends a
    request using giop 1.2. A service context offering bidirectional giop is
    sent with this request, and accepted by the server. The client provides
    the server (that supports giop 1.3) with a callback IOR that has iiop
    version 1.3, and the server attempts to call back on it.

    • may the callback use the incoming connection?
    • if so, what giop version should the request use?
    • if so using v1.2, what if the callback request requires a feature
      only available in giop 1.3?

interop issue: what system exceptions may be raised on GIOP 1.0?

  • Key: CORBA24-2
  • Legacy Issue Number: 2819
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: An issue we"ve run across is enumerating the set of system exceptions
    that are valid to be passed via GIOP 1.0 (and similarly for 1.1, and
    1.2). This is important for implementations of GIOP, which are, for
    instance, attempting to map wire exceptions to C++ exceptions, and is
    also important for packet-sniffing implementations.

    Since many conforming GIOP 1.0 implementations were built (and bought)
    and incorporated into products before various CORBA system exceptions
    were added to the Core, it seems that servers should not raise `newer"
    exceptions back to older clients – that is, clients speaking GIOP 1.0.
    Instead, they should map those `newer" exceptions to UNKNOWN, I"d guess.
