- Create a file with image name plus extension ".lock" if an image is opened
in read/write mode. This file will be deleted after closing the image.
- Check for a lock file before opening an image and fail if it exists.
- Check for a lock file before creating a undoable/volatile redolog file and
fail if it exists.
- 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
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
- 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)
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).
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)
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
- set timestamp of r/o disk in volatile mode, too (for save/restore support)
- TODO: save state function for the remaining image modes, restore support
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
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)
