/*
----- Change history -----
20090131: v0.1.0 released
* Some minor things have still to be done.
* Mounting ewf as dd: Seems to work. Diff didn't complain about
changes between original dd and emulated dd.
* Mounting ewf as vdi: Seems to work too. VBox accepts the emulated
vdi as valid vdi file and I was able to mount the containing fs
under Debian. INFO: Debian freezed when not using mount -r !!
20090203: v0.1.1 released
* Multiple code improvements. For ex. cleaner vdi header allocation.
* Fixed severe bug in image block calculation. Didn't check for odd
input in conversion from bytes to megabytes.
* Added more debug output
20090210: v0.1.2 released
* Fixed compilation problem (Typo in image_init_info() function).
* Fixed some problems with the debian scripts to be able to build
packages.
* Added random generator initialisation (Makes it possible to use
more than one image in VBox at a time).
20090215: * Added function init_cache_blocks which creates / loads a cache
file used to implement virtual write capability.
20090217: * Implemented the fuse write function. Did already some basic tests
with dd and it seems to work. But there are certainly still some
bugs left as there are also still some TODO's left.
20090226: * Changed program name from mountewf to xmount.
* Began with massive code cleanups to ease full implementation of
virtual write support and to be able to support multiple input
image formats (DD, EWF and AFF are planned for now).
* Added defines for supported input formats so it should be possible
to compile xmount without supporting all input formats. (DD
input images are always supported as these do not require any
additional libs). Input formats should later be en/disabled
by the configure script in function to which libs it detects.
* GetOrigImageSize function added to get the size of the original
image whatever type it is in.
* GetOrigImageData function added to retrieve data from original
image file whatever type it is in.
* GetVirtImageSize function added to get the size of the virtual
image file.
* Cleaned function mountewf_getattr and renamed it to
GetVirtFileAttr
* Cleaned function mountewf_readdir and renamed it to GetVirtFiles
* Cleaned function mountewf_open and renamed it to OpenVirtFile
20090227: * Cleaned function init_info_file and renamed it to
InitVirtImageInfoFile
20090228: * Cleaned function init_cache_blocks and renamed it to
InitCacheFile
* Added LogMessage function to ease error and debug logging (See
also LOG_ERROR and LOG_DEBUG macros in xmount.h)
* Cleaned function init_vdi_header and renamed it to
InitVirtVdiHeader
* Added PrintUsage function to print out xmount usage informations
* Cleaned function parse_cmdline and renamed it to ParseCmdLine
* Cleaned function main
* Added ExtractVirtFileNames function to extract virtual file names
from input image name
* Added function GetVirtImageData to retrieve data from the virtual
image file. This includes reading data from cache file if virtual
write support is enabled.
* Added function ReadVirtFile to replace mountewf_read
20090229: * Fixed a typo in virtual file name creation
* Added function SetVirtImageData to write data to virtual image
file. This includes writing data to cache file and caching entire
new blocks
* Added function WriteVirtFile to replace mountewf_write
20090305: * Solved a problem that made it impossible to access offsets >32bit
20090308: * Added SetVdiFileHeaderData function to handle virtual image type
specific data to be cached. This makes cache files independent
from virtual image type
20090316: v0.2.0 released
20090327: v0.2.1 released
* Fixed a bug in virtual write support. Checking whether data is
cached didn't use semaphores. This could corrupt cache files
when running multi-threaded.
* Added IsVdiFileHeaderCached function to check whether VDI file
header was already cached
* Added IsBlockCached function to check whether a block was already
cached
20090331: v0.2.2 released (Internal release)
* Further changes to semaphores to fix write support bug.
20090410: v0.2.3 released
* Reverted most of the fixes from v0.2.1 and v0.2.2 as those did not
solve the write support bug.
* Removed all semaphores
* Added two pthread mutexes to protect virtual image and virtual
info file.
20090508: * Configure script will now exit when needed libraries aren't found
* Added support for newest libewf beta version 20090506 as it seems
to reduce memory usage when working with EWF files by about 1/2.
* Added LIBEWF_BETA define to adept source to new libewf API.
* Added function InitVirtualVmdkFile to build a VmWare virtual disk
descriptor file.
20090519: * Added function CreateVirtDir implementing FUSE's mkdir to allow
VMWare to create his <iname>.vmdk.lck lock folder. Function does
not allow to create other folders!
* Changed cache file handling as VMDK caching will need new cache
file structure incompatible to the old one.
20090522: v0.3.0 released
* Added function DeleteVirtFile and DeleteVirtDir so VMWare can
remove his lock directories and files.
* Added function RenameVirtFile because VMWare needs to rename his
lock files.
* VMDK support should work now but descriptor file won't get cached
as I didn't implement it yet.
20090604: * Added --cache commandline parameter doing the same as --rw.
* Added --owcache commandline parameter doing the same as --rw but
overwrites any existing cache data. This can be handy for
debugging and testing purposes.
* Added "vmdks" output type. Same as "vmdk" but generates a disk
connected to the SCSI bus rather than the IDE bus.
20090710: v0.3.1 released
20090721: * Added function CheckFuseAllowOther to check wether FUSE supports
the "-o allow_other" option. It is supported when
"user_allow_other" is set in /etc/fuse.conf or when running
xmount as root.
* Automatic addition of FUSE's "-o allow_other" option if it is
supported.
* Added special "-o no_allow_other" command line parameter to
disable automatic addition of the above option.
* Reorganisation of FUSE's and xmount's command line options
processing.
* Added LogWarnMessage function to output a warning message.
20090722: * Added function CalculateInputImageHash to calculate an MD5 hash
of the first input image's HASH_AMOUNT bytes of data. This hash is
used as VDI creation UUID and will later be used to match cache
files to input images.
20090724: v0.3.2 released
20090725: v0.4.0 released
* Added AFF input image support.
* Due to various problems with libewf and libaff packages (Mainly
in Debian and Ubuntu), I decided to include them into xmount's
source tree and link them in statically. This has the advantage
that I can use whatever version I want.
20090727: v0.4.1 released
* Added again the ability to compile xmount with shared libs as the
Debian folks don't like the static ones :)
20090812: * Added TXMountConfData.OrigImageSize and
TXMountConfData.VirtImageSize to save the size of the input and
output image in order to avoid regetting it always from disk.
20090814: * Replaced all malloc and realloc occurences with the two macros
XMOUNT_MALLOC and XMOUNT_REALLOC.
20090816: * Replaced where applicable all occurences of str(n)cpy or
alike with their corresponding macros XMOUNT_STRSET, XMOUNT_STRCPY
and XMOUNT_STRNCPY pendants.
20090907: v0.4.2 released
- * Fixed a bug in VMDK lock file access. VirtualVmdkLockFileDataSize
+ * Fixed a bug in VMDK lock file access. glob_vmdk_lockfile_size
wasn't reset to 0 when the file was deleted.
* Fixed a bug in VMDK descriptor file access. Had to add
- VirtualVmdkFileSize to track the size of this file as strlen was
+ glob_vmdk_file_size to track the size of this file as strlen was
a bad idea :).
20100324: v0.4.3 released
* Changed all header structs to prevent different sizes on i386 and
amd64. See xmount.h for more details.
20100810: v0.4.4 released
* Found a bug in InitVirtVdiHeader(). The 64bit values were
addressed incorrectly while filled with rand(). This leads to an
error message when trying to add a VDI file to VirtualBox 3.2.8.
20110210: * Adding subtype and fsname FUSE options in order to display mounted
source in mount command output.
20110211: v0.4.5 released
20111011: * Changes to deal with libewf v2 API (Thx to Joachim Metz)
20111109: v0.4.6 released
* Added support for DMG output type (actually a DD with .dmg file
extension). This type is used as default output type when
using xmount under Mac OS X.
20120130: v0.4.7 released
* Made InitVirtImageInfoFile less picky about missing EWF infos.
20120507: * Added support for VHD output image as requested by various people.
* Statically linked libs updated to 20120504 (libewf) and 3.7.0
(afflib).
20120510: v0.5.0 released
* Added stbuf->st_blocks calculation for VHD images in function
GetVirtFileAttr. This makes Windows not think the emulated
file would be a sparse file. Sparse vhd files are not attachable
in Windows.
20130726: v0.6.0 released
* Added libaaff to replace libaff (thx to Guy Voncken).
* Added libdd to replace raw dd input file handling and finally
support split dd files (thx to Guy Voncken).
20140311: v0.7.0 released
* Added libaewf (thx to Guy Voncken).

/*
----- Change history -----
20090226: * Added change history information to this file.
* Added TVirtImageType enum to identify virtual image type.
* Added TOrigImageType enum to identify input image type.
* Added TMountimgConfData struct to hold various mountimg runtime
options.
- * Renamed VDIFILEHEADER to TVdiFileHeader.
+ * Renamed VDIFILEHEADER to ts_VdiFileHeader.
20090228: * Added LOG_ERROR and LOG_DEBUG macros
* Added defines for various static VDI header values
* Added defines for TRUE and FALSE
20090307: * Added defines for various static cache file header values
* Added VdiFileHeaderCached and pVdiFileHeader values to be able to
cache the VDI file header separatly.
20090519: * Added new cache file header structure and moved old one to
- TCacheFileHeader_v1.
+ ts_CacheFileHeader_v1.
* New cache file structure includes VmdkFileCached and pVmdkFile to
cache virtual VMDK file and makes room for further additions so
current cache file version 2 cache files can be easily converted
to newer ones.
20090814: * Added XMOUNT_MALLOC and XMOUNT_REALLOC macros.
20090816: * Added XMOUNT_STRSET, XMOUNT_STRNSET, XMOUNT_STRAPP and
XMOUNT_STRNAPP macros.
20100324: * Added "__attribute__ ((packed))" to all header structs to prevent
different sizes on i386 and amd64.
20111109: * Added TVirtImageType_DMG type.
20120130: * Added LOG_WARNING macro.
- 20120507: * Added TVhdFileHeader structure.
+ 20120507: * Added ts_VhdFileHeader structure.
20120511: * Added endianess conversation macros
