From: Andreas Otto on 8 Mar 2010 08:43 Dear User, ANNOUNCE: Major Feature Release ==================================== libmsgque: Application-Server-Toolkit for C, C++, JAVA, C#, TCL, PERL, PYTHON, VB.NET PLMK: Programming-Language-Microkernel NHI1: Non-Human-Intelligence #1 SUMMARY ======= This is a 'major-feature-release' to add 'longtime-transaction' support. A 'longtime-transaction' is a transaction with a possible infinite time period between the start and the end. A 'longtime-transaction' is always a 'persistent-transaction' too. The 'persistent' support is available as an in-memory solution on the 'application-server' or in an additional 'bidirectional-filter' available for the next release. A typical scenario for a 'longtime-transaction' is: * A user with a client connect to the server and start a 'longtime-transaction' job. After a while the user shutdown the client and leave the office. At the next morning the user start the client again and the results are send from the server to the client. * On a space mission the time-overhead between transaction start and end is large. It is usually not possible to keep the client-server-connection open all the time. * On a military action-system the enemy try to interrupted the client-server-connection to disable data communication. To use a 'longtime-transaction' the results are send to a 'client-service' registered with MqServiceCreate. This service and addtional data (I call this data 'local-context-data') have to be added to the 'longterm-transaction' package to be available in the result. On the 'link-target' the 'local-context-data' is initial stripped from the 'data-package' and is later added to the results again. The 'local-context-data' is added to the 'data-package' with MqSendT_START and MqSendT_END. The 'local-context-data' is read from the 'data-package' with MqReadT_START and MqReadT_END.
