@ajnelson hivexml: Do not print null input times
Dealing with "1601-01-01T00:00:00Z" is unnecessarily awkward, especially
since the value only represents a 0 found in the data.

@hillu hillu hivex: Added gnulib includes from builddir, as suggested by the Gnuli…
…b documentation; link hivexml against libgnu.

    Since some modules (`getopt', for example) may copy files
    into the build directory, `top_builddir/lib' is needed as well as
    `top_srcdir/lib'. -- GNU Gnulib manual, section 2.2 Initial import

This fixes an in-tree build failure on a Debian/sid system (see
below). hivexml could be built out-of-tree, but it turned out that due
to a missing include path, in this case the system's getopt
implementation was used insted of Gnulib's.

@ajnelson hivexml: Add byte run reporting functions
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.

Peter Fokker patch for read support of "li"-records from "ri" intermediate
Richard,

Thank you for creating the hivex-library. Studying your source code helped
me a great deal to better understand the internals of the Windows Registry.

However, while I was browsing a real-world SOFTWARE-hive (XP, SP3) I
could not browse to the '\Classes' key. Instead I got this (debug)-message:

    get_children: returning ENOTSUP because ri-record offset does not
point to lf/lh (0x49020)

I tracked this issue down and I discovered that the intermediate
"ri"-record may not only contain offsets to "lf" and "lh" but to
"li"-records too.

Attached is a patch against hivex.c v1.3.3 that recognises
"li"-records referenced from "ri"-records. For me this fixed the issue
with browsing the '\Classes' key.

Note that I have not fixed the related problem of rewriting
"li"-records when inserting a new subkey or deleting an
existing one. This sure would cause problems when I were to
add/delete a subkey to/from '\Classes'.

RWMJ:
The original patch submitted is here:
https://www.redhat.com/archives/libguestfs/2012-March/msg00035.html
Changes made:
 - Removed commented-out code for writing.
 - Re-added some checking code to reduce the delta of this patch
   to the previous code.  The checks can be removed in a separate
   patch if necessary.

I rewrote the function to be more sane.

@rwmjones rwmjones arm: Prevent cast-align warnings.
The implicit alignment of char* is 1 byte, so on ARM we get a
cast-align warning whenever we try to cast this to a larger type
(eg. casting to uint32_t).

The implicit alignment of void* is whatever malloc returns, and so
this can be cast to any type.

The cost of this is that we have to add (char *) casts all over the
code, but this seems unavoidable.

Thanks: Leif Lindholm, Peter Robinson.

@ajnelson Mac OS X: Link iconv in libhivex
hivexml on OS X was failing with a symbol-not-found error while
dynamically linking.  Adding iconv to libhivex fixes the issue and lets
OS X process 'images/large' with hivexml.

It took careful iconv autotool additions to get compilation working in
Fedora as well, but these two lines build and run on OS X 10.6 and
10.8, and Fedora 17 and 18.

Unfortunately, a separate issue is revealed here in OS X, as some of
the hivexml value data appears as Kanji.  However, that is an issue
distinct from getting the program to run.

@hillu hillu Relax size checks for integer types
I recenetly came across a Windows XP image, where one REG_QWORD value
(HKLM\Software\Microsoft\Windows\CurrentVersion\Group Policy\State\Machine\Scripts\Shutdown\0\0\ExecTime)
would be displayed by hivexsh but hivex_value_qword() would return -1.

It turned out that the data length of this value was 16 bytes instead
of 8.

There is no problem in simply interpreting the first 4 (DWORD) or
8 (QWORD) bytes -- if there are enough bytes to be interpreted.

@hillu hillu Add read support for "big data" blocks to hivex
Large values are split into multiple blocks. References to these
sub-blocks are kept in a list whose structure seems to be identical to
a value list.

A "db" record contains information on the number of sub-blocks and a
pointer to the list. It is referenced by the vk record.

I came across this when comparing the contents of HKLM\SOFTWARE hives
from Windows7 systems and finding that hivex_value_value would only give
me identical first 12 bytes for certain records though the data size had
changed. If one runs hivexsh with debug messages enabled, it gives a
warning when listing these values, for example:

SOFTWARE\Microsoft\SystemCertificates\AuthRoot\AutoUpdate> lsval
[...]
hivex_value_value: warning: declared data length is longer than the
block it is in (data 0x28b9b60, data len 115347, block len 16)

  git grep -P 'le\d+toh\s*\([^)]*\+'

@ajnelson lib: Promote byte_conversions.h #include to hivex-internal.h
This patch addresses a build failure in OS X.  Running git-bisect on a
straightforward build (bootstrap, autogen.sh, configure, make, make
install) showed this as the "Bad commit:"
3e7c039

The issue is that hivex-internal.h uses le32toh in a static inline
function.  In case `configure` doesn't find le32toh, byte_conversions.h
defines it.  But hivex-internal.h doesn't include the safety definition.

OS X demonstrates this a problem.  Neither endian.h nor byteswap.h are
found with `configure` in OS X 10.8.5 (XCode 5), but the headers are
both found in Fedora 19 and Ubuntu 13.04.  This patch to configure.ac
further logs that only ntohl is available for byte swaps:

    @@ -153,6 +153,8 @@ AC_REPLACE_FUNCS([mmap])
     dnl Functions.
     AC_CHECK_FUNCS([bindtextdomain])

    +AC_CHECK_FUNCS([le32toh ntohl bswap_32 __bswap_32])
    +

(As an aside, it's curious that a missing byteswap.h didn't cause
hivex-internal.h to fail to build.)
(As another aside, this is an interesting example of lazy symbol
binding failing with an inline function.)

The problem is resolved by having hivex-internal.h include
byte_conversions.h.  This obviates most of the other direct inclusions
of byte_conversions.h.  (One persists under sh/.)

This patch builds and runs hivexml on images/large fine in Ubuntu 13.04
and Fedora 19.  It also allows builds to succeed in OS X, but doesn't
run hivexml for an unrelated reason.  The _iconv_open
symbol-not-found issue, that I thought was previously resolved
(491ba0f), resurfaced.

Convert the tests to the MiniTest test framework, but keeping the usage

@Lekensteyn Lekensteyn Fix overly long assertion string
With GCC 4.9.1 I get a -Woverlength-strings warning:
hivex-internal.h:123:23: error: string length ‘3823’ is greater than ...
   (STREQLEN (((struct ntreg_hbin_block *)((char *) (h)->addr + (offs)))->id, (eqid), 2))

The compile command can be shortened to:

    cd lib && cpp -DHAVE_CONFIG_H -I.. -I../gnulib/lib  -I. \
        -Woverlength-strings -Werror -g -O2 write.c

After that, be amazed at the huge assertion string produced by the
macro which is also visible in libhivex.so (two times).

To fix that mess, use an inline function. The `STR*` macros were moved
and a string.h header added since STREQLEN is used in the function.

@Lekensteyn Lekensteyn python: use errors more specific than RuntimeError
KeyError is documented as:
"Raised when a mapping (dictionary) key is not found in the set of
existing keys."

TypeError is documented as:
"Raised when an operation or function is applied to an object of
inappropriate type."

RuntimeError is documented as:
"Raised when an error is detected that doesn’t fall in any of the other
categories."

Let's be more specific with exceptions. The exception all inherit from
StandardError (and from Exception), but not from RuntimeError, so this
might need some code changes (if users would catch this specific error).
However, this behavior was not documented so it is perfectly fine to
change it.

@Lekensteyn Lekensteyn python: fix crash by validating key and value
User-visible changes: no crashes if you try to pass a non-str type as
key/value in Python 3. Exceptions are thrown rather than silently
ignoring type violations (such as passing a Unicode string as value
in Python 2).

Until now, Python 2 keys and values were assumes to be bytes, in
Python 3 these were seen as Unicode strings instead. Remove the
compile-check for a deprecated Python 2 function (`PyString_AsString`)
and check for byte types instead.

For keys, accept both strings and bytes as the common case is to pass
a ASCII string name. (The `\u20ac` Unicode character (Euro-sign) is
apparently also valid as key name, verified with Python 3 and
Windows 7).

For values, be more conservative and reject all types except bytes. This
better matches the C API and removes the burden of character conversion
from the wrapper. Instead, callers should know the correct encoding
and terminate strings.

Modify tests to specify bytes instead of strings. (Otherwise Python 3
would break while Python 2 still passes.)

…t (RHBZ#1145056).

hivex_value_data_cell_offset may return 0 to indicate that the data is
inline.  This is not an error return, but it was possible for errno to
have a random (non-zero) value along this path.  Explicitly set errno
= 0 on this path.

@ptoscano ptoscano Fix shebang in perl scripts
Instead of hardcoding the location of perl (assuming it is installed in
/usr), use /usr/bin/env to run it, and thus picking it from $PATH.
This makes it possible to run these scripts also on installations with
perl in a different prefix than /usr.

Also, given that we want enable warnings on scripts, turn the -w
previously in shebang to explicit "use warnings;" in scripts which
didn't have it before.
