That kind of implicit includes should really only be done when totally,
absolutely necessary, and ideally only with rather simple 'second-level'
headers.
Otherwise not being explicit with includes always end up biting in
unexpected ways...
- Move static undo variable into 'WriteData',
'memfile_chunk_add' used arguments in a confusing way,
sometimes to set/clear static var.
- Replace checks for 'wd->current' with 'wd->use_memfile'
move memfile vars into 'wd->mem' struct.
- Use a single undo history for all operations.
- UndoType's are registered and poll the context to check if they
should be used when performing an undo push.
- Mode switching is used to ensure the state is correct before
undo data is restored.
- Some undo types accumulate changes (image & text editing)
others store the state multiple times (with de-duplication).
This is supported by checking UndoStack.mode `ACCUMULATE` / `STORE`.
- Each undo step stores ID datablocks they use with utilities to help
manage restoring correct ID's.
Needed since global undo is now mixed with other modes undo.
- Currently performs each undo step when going up/down history
Previously this wasn't done, making history fail in some cases.
This can be optimized to skip some combinations of undo steps.
grease-pencil is an exception which has not been updated
since it integrates undo into the draw-session.
See D3113
- Get memory usage from MemFile instead of MEM API
avoids possible invalid when threads alloc memory.
- Use size_t instead of uint and uintptr_t to store size.
- Rename UndoElem.str -> filename
- Rename MemFileChunk.ident -> is_identical
`my_memcmp` didn't work properly comparing memory sizes not aligned to 4 bytes,
this worked while we used guarded-alloc (which always wrote a guard at the end of each allocation).
Since moving to lockfree allocator it could read uninitialized memory.
It also consistently performed ~10-30% worse then glibc's.
This is typically well optimized, no need to do ourselves.
NOTE: BLI_winstuff.h was meant to be a wrapper around windows.h to handle
undefining various crap that windows.h defines. Platform specific headers
should only have to be included in a few places. This reduces the number
of inclusions of BLI_winstuff.h to 16 which is a much more reasonable
number (than the 144 or whatever it used to be)
- Made unified API for undo calls, to be found in space.c
BIF_undo_push(char *str)
BIF_undo(void)
BIF_redo(void)
These calls will do all undo levels, including editmode and vpaint.
The transition is work in progress, because mesh undo needs recode.
- New global hotkey CTR+Z for undo
Note: 'shaded draw mode' still is SHIFT+Z, the old CTRL+Z was to recalc
the lighting in shaded mode, which already became much more interactive,
like during/after any transform().
Recalc hotkey now is SHIFT+ALT+Z
CTRL+<any modifier>+Z is redo.
- For OSX users; the Apple-key ("Command") now maps to CTRL as well. This
disables the one-mouse-button hack for rightmouse btw, will be fixed in
next commit. At least we can use Apple-Z :)
- Old Ukey for undo is still there, as a training period... my preference is
to restore Ukey to "reload original data" as in past, and only use new
CTRL+Z for undo.
- Added undo_push() for all of editobject.c and editview.c. Meaning we can
start using/testing global undo in the 3d window. Please dont comment on
missing parts for now, first I want someone to volunteer to tackle all of
that.
- Since the global undo has a full 'file' in memory, it can save extremely
fast on exit to <temp dir>/quit.blend. That's default now when global undo
is enabled. It prints "Saved session recovery to ..." in console then.
- In file menu, a new option is added "Recover Last Session". Note that this
reads the undo-save, which is without UI.
- With such nice new features we then can also kill the disputed
Cancel/Confirm menu on Q-KEY.
- Added fix which initializes seam/normal theme color on saved themes.
They showed black now.... (Note: that's in usiblender.c!)
