similar to: [hivex] [PATCH 2/2] hivex: Expose embedded hive file name

The major and minor version were being reported in a debug message. This patch adds the version information to the ABI and reports with hivexml.

The infrastructure for modified-time reporting has been essentially unused. These changes report the registry time by treating the time fields as Windows filetime fields stored in little-Endian (which means they can be treated as a single 64-bit little-Endian integer). This patch adds to the hivex ABI: * int64_t hivex_last_modified (hive_h *) * int64_t hivex_node_timestamp (hive_h *,

This patch adds byte run reporters for node and value metadata in the hivexml program. Each byte run represents the offset and length of a data structure within the hive, one per node, and one or two per value depending on the length of the value data. In order to add this metadata reporting, the following changes were put in place: * Split value_key function into value_key and value_key_len. *

The infrastructure for modified-time reporting has been essentially unused. These changes report the registry time by treating the time fields as Windows filetime fields stored in little-Endian (which means they can be treated as a single 64-bit little-Endian integer). Some of the code changes necessary include: * Exposing the hive_h structure in the hivex header file (via generator.ml) *

This patch adds value_byte_runs and node_byte_runs. Each byte run represents the offset and length of a data structure within the hive, one per node, and one or two per value depending on the length of the value data. These byte run functions also add additional data sanity checks as a hive is being parsed, mainly checking that a node address actually points to a node, and similarly for values.

Reporting value data in attributes has two advantages: * The output of hivexml breaks Python expat processing if binary data makes it out. This was observed in Software hives. * Not having child text makes room for child elements.

Some of the data in names and string values were being unsafely printed, causing some types of XML processors to fail (e.g. Python's Expat).

There's a new syntax check rule from gnulib. It requires that you write e.g., exit (EXIT_SUCCESS), not exit (0). And the same for 1/EXIT_FAILURE and any other constants. There were a lot of violations, including a few false positives, so I started with the exemptions (see the .x-sc file below). Then I converted the vast majority automatically, with this: maint: use EXIT_SUCCESS and

This patch adds hivex_node_struct_length and hivex_value_struct_length to the hivex ABI, to report the amount of hive space used for each stored structure.

All, I am using a pretty crude method to get data out of HDFS via Hive and into R and was curious about alternatives that the group has explored. Basically, I run a system command that runs a hive statement and writes the returned data to a delimited file. Then, I read that file into an object and continue. For example: hive.script <- "select * from orders where date =
