Revision history for Perl extension Parse::Win32Registry. ** 1.0 2012-04-29 Added support for decoding System Mandatory Label ACEs (a feature introduced with Windows Vista) and added the command line script regml.pl for listing keys with explicit System Mandatory Label ACEs set. Improved handling of security descriptors. Tidied up various aspects of the wxWidgets and GTK applications, and harmonised functionality between the various pairs of equivalent programs, with a minor difference being the wxWidgets applications following Windows keyboard shortcut conventions while the GTK applications following Linux keyboard shortcut conventions. The get_data method of Value objects now returns the unpacked integer value for REG_DWORD_BIG_ENDIAN value types instead of the original packed binary data. Added support for values with 'big data'. Thanks to Harlan Carvey for all his help with this. ** 0.60 2010-08-15 Parse::Win32Registry now requires Perl 5.8.1. Implemented new RGKN and RGDB Block objects for Windows 95 registry files. Now both Windows 95 and Windows NT registry files have a get_block_iterator method, which replaces the get_hbin_iterator previously provided for Windows NT registry files. (For backwards compatibility, calling the get_hbin_iterator method will call the get_block_iterator method.) Some performance improvements have been made to the processing of REG_MULTI_SZ value data (in the get_data method of Value objects), to the generation of hexdumps (in the hexdump function and the unparsed method of Entry objects), and to the generation of REGEDIT-style octet strings (in the as_regedit_export method of Value objects). Uncompressed (Unicode) key and value names are now correctly read from Windows NT registry files. The following new scripts have been added: wxregcompare.pl, wxregscope.pl, and wxregview.pl. The existing regcompare.pl, regscope.pl, and regview.pl scripts have been renamed to gtkregcompare.pl, gtkregscope.pl, and gtkregview.pl respectively. The wx scripts require Mattia Barbon's wxPerl library and the gtk scripts require Gtk-Perl. (Binary versions of wxPerl are currently available in ActivePerl.) gtkregscope.pl and wxregscope.pl use the new get_block_iterator method, so can read both Windows 95 or Windows NT registry files. gtkregcompare.pl and wxregcompare.pl allow the Select Files dialog to be cancelled to make it possible to review the currently selected files. regmultidiff.pl now displays changes in a summary mode. The previous format is available by specifying the -l or --long option. ** 0.51 2009-10-04 Added new regscope.pl script, a GTK+ registry entry viewer that uses color to highlight different types of registry entries. Documented the get_name method of SID objects and the get_value_data method of Key objects. The as_string method of the ACE object and the as_stanza method of the SecurityDescriptor object now include the well known SID names (as returned by each SID object's get_name method). Updated the regview.pl and regcompare.pl scripts: regview.pl and regcompare.pl can now select keys and/or values when searching, regview.pl can now sort columns (e.g. keys can be sorted by timestamp, values by type, etc), regcompare.pl can now bookmark keys or values, and regview.pl now has a basic report view. Fixed the get_subtree_iter and make_multiple_subtree_iterator methods to return the root key(s) of the subtree(s) as the documentation indicates. regview.pl, regmultidiff.pl, and regcompare.pl amended to accommodate these changes. Fixed redisplay problem closing dialogs using Escape in regview.pl and regcompare.pl. Makefile.pl now includes all scripts as exe_files. ** 0.50 2009-07-19 Security information is now extracted from Windows NT registry files. Key objects now provide a get_security method which returns a new Security object. The various methods of a Security object will return Security Descriptor, ACL, ACE, and SID objects. The support functions unpack_sid, unpack_ace, unpack_acl, and unpack_security_descriptor have been added to allow the manual extraction of security information from value data. The support functions compare_multiple_keys and compare_multiple_values have been added for comparing keys and values. Updated scripts: regview.pl now provides searches and displays security information for keys. regtree.pl now draws lines connecting subkeys to their parent keys. regdump.pl can now display class names and security information. regfind.pl and regtimeline.pl can now display value data as a hexdump, and regfind.pl now searches raw data for unicode matches. New scripts: regmultidiff.pl is a command line program for comparing multiple registry files, and replaces regdiff.pl. regcompare.pl is a GTK+ Registry Compare program, and also provides searches. regsecurity.pl displays registry security entries. regshell.pl is a interactive console program for browsing registry files that offers tab completion of key and value names if Term::Readline is available. Iterators for processing keys and values have now been added, mainly to support GUI programs (see regview.pl and regcompare.pl). Key objects now offer the get_subkey_iterator, get_value_iterator, and get_subtree_iterator methods. The support functions make_multiple_subkey_iterator, make_multiple_value_iterator, and make_multiple_subtree_iterator have been added for processing multiple registry files simultaneously. Similarly, iterators have been added for scanning registry files entry by entry. The new Hbin object has been created to represent the individual hbins that make up Windows NT registry files. Now you can either iterate through all the entries in a registry file, or iterate through all the hbins in a registry file and through each entry of each hbin. The as_hexdump method provided by Entry, Key, and Value objects has been renamed to unparsed to more accurately reflect what it shows. The Entry, Key, and Value objects now provide the following methods: get_length, get_tag, is_allocated, get_raw_bytes, looks_like_key, looks_like_value, and looks_like_security. Warnings generated by parse errors are now disabled by default. ** 0.41 2008-12-14 Added the new get_class_name function for Windows NT registry keys. Added the regclassnames.pl script to demonstrate finding keys that have class names, and updated regview.pl to display the timestamp and class names of keys in additional columns. ** 0.40 2008-09-28 Added new scripts: regexport.pl for exporting keys and values using the Windows Registry Editor Version 5.00 format, regscan.pl for dumping all the entries in a registry file, regstats.pl for providing basic statistics, regtimeline.pl for listing keys and values in date order, regtree.pl for dumping a registry file as an intended tree, and regview.pl, a GTK+ Registry Viewer. Updated regdump.pl and regfind.pl to provide new options. Changed parse errors to generate warnings instead of croaking. Documented this in the Handling Invalid Data section. The get_data method of Value objects now handles REG_MULTI_SZ data by returning a list of its elements in an array context, and a string in a scalar context. The output of get_data_as_string is unaffected. Added new Registry object methods: get_virtual_root_key, get_timestamp, get_timestamp_as_string, and get_embedded_filename. Added new Key object methods: as_regedit_export, get_parent, and is_root. Added new Value object methods: as_regedit_export, and get_raw_data. Added the get_next_entry and move_to_first_entry methods to the Registry object for iterating through all the entries in a registry file. Added the Entry object class as a generic object to represent these entries. Added the methods parse_info and as_hexdump to Entry, Key, and Value objects. Support function convert_filetime_to_epoch_time renamed to unpack_windows_time, added the function unpack_unicode_string, and documented hexdump. ** 0.30 2007-07-01 Added two new scripts: regfind.pl for searching keys, values, and data for a search string, and regdiff.pl for comparing two registry files and displaying the differences. dumpreg.pl renamed to regdump.pl and command line options simplified. Introduced the as_string method for Key and Value objects. This is intended to be a more usable replacement for the print_summary method. The get_data_as_string method changed to return REG_DWORD values as a hexadecimal number followed by its decimal equivalent. Clarified that REG_DWORD values are returned as unsigned integers. Support functions convert_filetime_to_epoch_time and iso8601 documented. Fixed bugs handling unusual key names in the get_subkey method. ** 0.25 2006-11-12 Fixed a bug with new WinNT key objects incorrectly setting the offsets to subkey lists and value lists when the offset to the parent key had a particular value. ** 0.24 2006-10-29 Key objects now have a get_path method, which returns the path to that key from the root key of a registry file. Documentation updated to describe the new method. dumpreg.pl updated to use get_path. Dropped the prefix_pattern and long_prefix_pattern configuration options from Getopt::Long. (which required an unnecessarily recent version of Getopt::Long) ** 0.23 2006-08-13 Key objects now have the get_timestamp and get_timestamp_as_string methods, although only Windows NT registry keys will return valid values. print_summary nows also displays the timestamp for Windows NT registry keys. Documentation updated to reflect this. Makefile.PL now installs the dumpreg.pl script. ** 0.22 2006-08-06 Included the script dumpreg.pl as both a tool for examining registry files, and as an example. Offsets that require adjustment by fixed amounts (this applies to entries in the RGKN block of Windows 95 registry files and to all entries in the hbin blocks of Windows NT registry files) are now amended before being stored, rather than at seek time. Troubleshooting section added to the documentation. ** 0.21 2006-07-30 Checks added after every sysread, and improvements attempted for the error messages presented. Internal error messages have been made distinct from parse errors. The code that looks up the RGDB entry for Win95 keys has been revised to remove some duplicate code. It's still too long. Reading REG_DWORD values which are not the expected four bytes in length no longer results in an exception. get_data now returns undef for these values instead of failing. get_data_as_string updated to return (no data) when get_data returns an empty string, and (invalid data) when get_data returns undef (which should only occur for invalid REG_DWORD values). ** 0.20 2006-07-23 Released to CPAN.
