Methods and systems are disclosed which allow shifting inventory to fulfill guaranteed delivery advertisement contracts. Inventory may be allocated from a supply of unallocated inventory to one or more advertisers in accordance with guaranteed delivery agreements. Inventory may be reserved for the one or more advertisers from the remaining supply of unallocated inventory. Inventory may then be allocated to an additional advertiser by using unallocated inventory or shifted inventory, or a combination of unallocated inventory and shifted inventory. The shifted inventory is shifted out of the allocation for the first advertiser and the shifted inventory is replaced by the reserve inventory for the respective advertiser.

The present invention includes a native language verification method for verifying native language information associated with an emulation class. Verification information associated with native language code is obtained. The native language code is referred to by an emulation language class. The legitimacy of the verification information is examined to confirm the native language is uncorrupted.

A present invention emulation internal representation revision method performs revisions on internal representations. In one embodiment of the present invention, an indication of a revision to loaded emulation code is received. Conditions for maintaining consistency are created. An ordered listing for providing an index correspondence to the emulation code is revised. The information from the listing is incorporated in the internal representation of the emulation code, such that a virtual machine implementing the loaded emulation code is not shut down.

Emulation internal representation revision system and method

A present invention emulation class revision process performs emulation class revisions. In one embodiment of the present invention an indication of an emulation class revision initiation is received. A safe state for performing the emulation class revision is established. In one exemplary implementation the safe state retains prior processing results. An emulation class revision is performed.

Emulation class revision system and method

In upgrading a concentrated executable computer code with an upgrade code, indexed lists are created for the concentrated code and for the upgrade code. The indexed lists have index references for code identifiers of code structures in the concentrated code and the upgrade code, respectively. The indexed lists are stored in a virtual table. The concentrated code is integrated with the upgrade code to form an integrated code. The virtual table contains an operable part referable by the integrated code such that when a code structure being executed originates from the concentrated code the indexed list for the concentrated code is stored in the operable part of the virtual table, and when a code structure being executed originates from the upgrade code the indexed list for the upgrade code is stored in the operable part of the virtual table.

System and apparatus for dynamically upgrading concentrated executable computer software code

In upgrading a concentrated executable computer code with an upgrade code, a first indexed list is created of a plurality of index references corresponding to first identifiers of the first type code structures in the concentrated code, the first indexed list further containing upgrade flags to indicate whether corresponding first type code structures identified by the first identifiers have been upgraded. A first indexed upgrade list is created of a plurality of index references corresponding to first identifiers of the first type code structures in the upgrade code. A state of each upgrade flag is set to indicate whether a corresponding first identifier in the first indexed list has been upgraded based on comparing the first identifiers in the first indexed upgrade list with the first identifiers in the first indexed list.
