This meeting was between ajm4 and tdb1 to discuss and |
| 8 |
|
possibly implement parts of the CORE and FilterManager |
| 9 |
|
elements of the system. |
| 42 |
|
where thus implemented and the configurator test class |
| 43 |
|
modified to include a test of this system. |
| 44 |
|
|

< |
[tdb1: it was also noted at this stage that a java 'long' is |
| 46 |
< |
infact an IDL 'long long'.] |
| 45 |
> |
It should also be noted at this stage that a java 'long' is |
| 46 |

defined as a 'long long' in the IDL->Java mapping. |

The next item discussed was the CORBA IDL and general system |
| 74 |
|
thing a Host does is obtain its configuration, this is done |
| 75 |
|
by the HostInit object obtaining the configuration of the |
| 76 |
|
host on its behalf. An initial protocol of how this system |
| 77 |
< |
works is as follows: |
| 77 |
> |
works is as follows (of course this is subject to later |
| 78 |
> |
alteration, but seemed like a "good idea at the time"): |
| 79 |
|
|
| 81 |
– |
[tdb1: This is of course subject to alteration, but at the |
| 82 |
– |
time it seemed like a "good idea".] |

|
Host FilterManager.HostInit |
| 81 |
|
STARTCONFIG -> |
| 82 |
|
<- OK | ERROR |
| 90 |
|
ENDCONFIG -> |
| 91 |
|
<- OK |
| 92 |
|
|
| 93 |
+ |
If there is an ERROR returned after STARTCONFIG, this |
| 94 |
+ |
indicates to the Host that there is no configuration |
| 95 |
+ |
available for it at this time. It may be possible to |
| 96 |
+ |
continue using default values, but this is up to the host |
| 97 |
+ |
configuration. Again, this is not a certain feature and |
| 98 |
+ |
should be discussed with other members of the group. |
| 99 |
+ |
|
| 100 |
|
If the property section returns an ERROR then this indicates |
| 101 |
|
to the host that that property requested doesn't exist, the |
| 102 |
|
Host will then deal with this either by ending with an error |
| 103 |
|
on the local system or by ignoring it if it can. |
| 104 |
|
|
| 105 |
< |
[tdb1: An ERROR after STARTCONFIG indicates no configuration |
| 103 |
< |
is available at all (ie. no file found).] |
| 105 |

The above features were implemented. |

The above features where implemented. |

The next item needed to be developed is an architecture for |
| 110 |
|
FilterParent's and FilterChild's, as the next stage of Host |
| 111 |
< |
initialisation is to be passed a reference to a FilterChild. |
| 111 |
> |
initialisation is to be passed a 'reference' to a |
| 112 |
> |
FilterChild. This 'reference' will be a server and a port |
| 113 |
> |
and not a reference in the CORBA or Java way of thinking. |
| 114 |
|
|
| 111 |
– |
[tdb1: "passed a reference" will mean a server and a port, |
| 112 |
– |
not to be confused with Java or CORBA references.] |
| 113 |
– |
|
| 115 |
|
It was noted that on a "heart beat" with the system, a Host |
| 116 |
|
should check to see if its configuration has changed. If it |
| 117 |
|
has it should then re-initialise itself. This will allow |
| 129 |

All code generated was placed in the "experimental" tree of |
| 132 |
< |
CVS, awaiting approval from other group members. |

code during this meeting ;-p |

|
Many small bug fixes were made to the existing code. |
| 138 |
|
|
| 139 |
|
It was also noted that there is a need for coding standards. |

As we had reached an appropriate stage to end, and given the |
| 142 |
< |
late hour, it was decided to conclude the meeting. |
