Abstract: Systems and methods for implementing polymorphic allocators in an operating system are disclosed. An illustrative method includes a method of allocating memory space in a memory by creating a first allocator. In response to receiving a first request to allocate memory space in the memory for a data buffer instance using the first allocator, the method allocates one or more pages of a first region in the memory by populating one or more entries of an allocator table. The one or more entries of the allocator table correspond to the one or more pages of the first region. The entries of the allocator table are indexed by page indexes corresponding to page addresses identifying the pages of the first region in the memory. Each of the populated entries of the allocator table includes a specific allocator identifier identifying a corresponding allocator to that entry.

Abstract: Systems and methods for creating a new entry in a hierarchical state data structure with object entries is disclosed. The method includes allocating a shared memory buffer for a new entry in a shared memory. A request to create the new entry for a child object in a hierarchical state data structure in the shared memory is received. The new entry is to span at least one shared memory buffer uniquely identifiable in a location of the shared memory. The child object is a logical representation of a state of a system. In response to a request for an allocation of a shared memory buffer within a region of the shared memory for the new entry, a location identifier corresponding to a location of a parent entry holding a parent object to the child object in the hierarchical state data structure of an allocated region is received. The child object is created in the shared memory buffer for the new entry, and the new entry is available for concurrent access by one or more readers of the shared memory.

Abstract: Systems and methods for processing memory address spaces corresponding to a shared memory are disclosed. After a writer restart process, pre-restart writer pointers of a pre-restart writer addressable space in the shared memory are replaced with corresponding location independent pointers. A writer pointer translation table is rebuilt in the shared memory to replace an association of modified pre-restart writer pointers and pre-restart translation base pointers based on the pre-restart writer pointers, respectively, with an association of modified post-restart writer pointers and post-restart translation base pointers based on post-restart writer pointers, respectively. After the writer pointer translation table is rebuilt, the location independent pointers are replaced with post-restart writer pointers in the shared memory, respectively, and the post-restart writer pointers are stored in the shared memory for access by one or more readers of the shared memory.

Abstract: A table (1) has a table top (2) containing an opening (3). A heating appliance (10) is in the opening (3) wherein the heating appliance (10) extends at least beneath the table top (2). The table top opening (3) comprises a recess (5) in which the heating appliance (10) is received, and the recess (5) has at least one wall (7) below the table top (2). The heating appliance (10) has a substantially sealed chamber (13) for receiving combustible fuel (47) with which the heating appliance (10) is used, and the chamber (13) has at least one window (35, 45).

Abstract: A table (1) comprises a table top (4), a heating appliance (3), and a heating appliance holder (2) holding the heating appliance (3). The heating appliance holder (2) comprises a holder main body (7) and a table top holder (8) for holding the table top (4), the table top holder (8) being spaced apart from the holder main body (7) by at least one gap (20).

Abstract: Techniques are described herein for managing data structure groups. Such techniques may include providing to a data structure group, by a reader, a plurality of data structure identifiers including a first data structure identifier and a second data structure identifier; mounting, by the data structure group, a first data structure identified by the first data structure identifier and including a first instance identifier; mounting, by the data structure group, a second data structure identified by the second data structure identifier and including a second instance identifier; making a first determination that the first data structure and the second data structure are mounted; making a second determination that the first instance identifier and the second instance identifier match; and marking, based on the first determination and the second determination, the data structure group as ready-to-read.

Abstract: A method and apparatus of a device that grows and/or shrinks a table that is shared between a writer and a plurality of readers is described. In an exemplary embodiment, a device receives an entry to be added to the shared table. In response to receiving the entry, the device remaps shared table to add a new storage segment to the shared table. The device further adds the entry to the shared table, where the entry is stored in the new storage segment. In addition, the device updates a shared table characteristic to indicate that the shared table has changed. The device further shrinks the shared table by remapping the table to remove a segment of the table.
