9554a2133e Always enable the portable ISO image file support. The option --enable-cdrom now
only controls the presence of platform-specific code to access CDROM/DVD devices

b1d4a96983 Rewrite of the lowlevel cdrom code
- class cdrom_base_c now provides portable ISO image access methods
- platform specific classes implement access to cdrom/dvd devices

b452803be5 Preparing lowlevel cdrom rewrite
- use #if BX_SUPPORT_CDROM instead of #ifdef LOWLEVEL_CDROM
- devices with cdrom support now use the base class cdrom_base_c
- cdrom count variable moved to cdrom.cc
- cdrom_misc.cc: don't use ioctl's for ISO files

e29957cca2 Removed 'delete' (-d) option and added new 'backup' (-b) option.
In convert/resize mode a backup can be created if the new file name
is not specified or the same as the source file name. In commit mode
both base image and redolog file are affected by the backup switch.
Added Linux specific file copy code using '/bin/cp'.

2c779f60da bximage convert / resize: show source disk image mode

66b311a8a6 Some work on the new bximage utility
- added support to use 'concat' and 'dll' mode images as convert source.
  A prefix ("concat:" or "dll:") must be added to the path since autodetection
  doesn't work for these modes.
- create: fixed virtual disk size calculation based on C/H/S
- convert / resize (interactive mode): use original filename as the template for
  the new one if not specified on the command line

f622a042c4 Added initial version of a new bximage utility written in C++ for image
creation, conversion and rodolog commit. Image creation support is not
present yet and the executable has not been added to standard compile yet.
TODO #1: add floppy and hard disk image creation support (from bximage.c)
TODO #2: implement support for conversion to vmware and vpc formats
TODO #3: add MSVC (nmake and workspace) support

17970857b8 added new bx_param_string_c methods isempty() and sprint()
- isempty() returns 1 if string length is 0 or string has special value "none"
- sprint() copies the formatted / converted string into a buffer
- use new methods in some parts of the code (TODO: win32 dialogs)
- check for the special value "none" to avoid failures

698afee9aa undoable / volatile mode: added support for other types of r/o base images.
These hdimage modes are now supported: flat, sparse, growing, vmware3, vmware4
und vpc. The image mode is auto-detected, so no change of configuration syntax
is necessary (TODO: documentation update). Example:

ata0-master: type=disk, mode=volatile, path=vmware4-test.img

fb778e706c - sparse: simplified restore code
- redolog class: added support for opening redolog file in read-only mode
- open backups for header check in read-only mode (growing, undoable, volatile, vpc)

d6bdc0c18f vpc-img: implemented check_format() for image autodetection 2012-10-03 21:25:20 +00:00
Volker Ruppert
961a88ab43 - started implementation of hdimage mode autodetection and use it to check the
type of the r/o disk for the undoable / volatile mode. The format check code
  is currently written for flat, sparse and growing images. The undoable and
  volatile mode now cause a panic if the r/o image mode is unsupported.
- TODO #1: rewrite the header checks for vmware3, vmware4 and vpc images to make
  them usable for autodetection.
- TODO #2: add support for other types of r/o disks in undoable/volatile mode.
- TODO #3: add an image mode 'auto' for the supported types (NOTE: unknown images
  can be treated as flat ones if their size is multiple of 512).

b142dbcc2c - add new function hdimage_open_file() that returns file size and modification
time if requested (reduces code duplication)
- 'vpc' image mode: moved header check to a separate function that opens the
  file, checks header/footer and returns disk type (if requested)
- implemented restore function for 'vpc' mode images
- gui: updated yes/no dialog message after saving state
- save/restore documentation update (TODO: developer doc)

31461c26fb - added helper function hdimage_copy_file() for the hdimage restore functions.
On win32 the native CopyFile() function is used. The restore function should
  work this way: coherency check (if necessary), close current image, copy saved
  image from restore path (overwrites existing one), finally re-open image.
- implemented restore function for 'flat' and 'undoable' mode images
2012-09-22 10:04:28 +00:00

28bc5e4bc2 - moved coherency check for r/o disk and journal to a separate function to

bcd0a58537 - simplified save_state() method of 'sparse' mode images (saving parent images
not necessary, since all changes go to the toplevel image)
2012-09-20 20:41:14 +00:00
Volker Ruppert
50482a9f2b - implemented save state function for the disk image modes 'vmware3', 'vmware4'

7da5057be5 - implemented save state function for redolog_t based disk image modes (growing,
undoable, volatile)
- TODO: save state function for the remaining image modes, restore support
- save/restore: when saving binary data to a file, use the full parameter path
  (except "bochs." prefix) as the file name to avoid overwriting duplicates

9ee5a77747 - started implementation of sav/restore support for hard disk images using a
dummy parameter and it's save/restore handlers. Currently only the save
  support is implemented and the specific save function is only written for
  flat mode images (copies whole disk image file to the save/restore folder).
- TODO #1: implement save function for the other disk image modes
- TODO #2: add restore support (replace disk image file with the one from the
           save/restore folder)
