Dual logging of changes to a user preference in a computer device

A method for logging changes made to a user preference in a computer device, comprising:

• writing the changes made to the user preference into a configuration file in a short term memory of the computer device;
• in response to a first flush operation, writing the changes made to the user preference from the configuration file in the short term memory of the computer device to a log file of a pair of log files in a long term memory of the computer device, wherein each log file of the pair of log files in the long term memory comprises a header section divided into two subdivisions, each subdivision containing an identifier, and a time stamp section containing a time when either the identification operation or a flush operation occurred, a dirty vector section containing information that identifies the location of the changes made to the user preference written to the configuration file in the short term memory, a plurality of data sections, each data section containing the changes made to the user preference written from corresponding data sections of the configuration file in the short term memory;
• and
• in response to a first write operation after the completion of the first flush operation, writing the changes made to the user preference from the configuration file in the short term memory of the computer device to a configuration file in the long term memory of the computer device.

A method for logging changes made to a user preference in a computer device, comprising:

• writing the changes made to the user preference in a registry hive file in a short term memory of the computer device;
• in response to a flush operation, writing the changes made to the user preference from the registry hive file in the short term memory of the computer device to a hive log file of a pair of hive log files in a long term memory of the computer device, wherein the hive log file is identified by setting a marker associated with the hive log file before writing the changes, wherein each hive log file of the pair of hive log files in the long term memory comprises a header section divided into two subdivisions, each subdivision containing an identifier, and a time stamp section containing a time when either the identification operation or a flush operation occurred, a dirty vector section containing information that identifies the location of the changes made to the user preference written to the configuration file in the short term memory, a plurality of data sections, each data section containing the changes made to the user preference written from corresponding data sections of the configuration file in the short term memory;
• and
• in response to a write operation after the completion of the flush operation, (i) setting the marker from the hive log file of the pair of hive log files to another hive log file of the pair of hive log files in the long term memory;
• and (ii) writing the changes made to the user preference from the registry hive file in the short term memory of the computer device to a hive primary file in the long term memory of the computer device.
