Compressing blendfiles can help save a lot of disk space, but the slowdown
while loading and saving is a major annoyance.
Currently Blender uses Zlib (aka gzip aka Deflate) for compression, but there
are now several more modern algorithms that outperform it in every way.
In this patch, I decided for Zstandard aka Zstd for several reasons:
- It is widely supported, both in other programs and libraries as well as in
general-purpose compression utilities on Unix
- It is extremely flexible - spanning several orders of magnitude of
compression speeds depending on the level setting.
- It is pretty much on the Pareto frontier for all of its configurations
(meaning that no other algorithm is both faster and more efficient).
One downside of course is that older versions of Blender will not be able to
read these files, but one can always just re-save them without compression or
decompress the file manually with an external tool.
The implementation here saves additional metadata into the compressed file in
order to allow for efficient seeking when loading. This is standard-compliant
and will be ignored by other tools that support Zstd.
If the metadata is not present (e.g. because you manually compressed a .blend
file with another tool), Blender will fall back to sequential reading.
Saving is multithreaded to improve performance. Loading is currently not
multithreaded since it's not easy to predict the access patterns of the
loading code when seeking is supported.
In the future, we might want to look into making this more predictable or
disabling seeking for the main .blend file, which would then allow for
multiple background threads that decompress data ahead of time.
The compression level was chosen to get sizes comparable to previous versions
at much higher speeds. In the future, this could be exposed as an option.

Instead of handling mmap, compression etc. all directly in readfile.c, refactor
the code to use a generic FileReader.
This makes it easier to add new compression methods or similar, and allows to
reuse the logic in other places (e.g. thumbnail reading).

Extend the 'reading error' container to produce the generic short
message in the popup directly visible by the user, and move all detailed
info the `INFO` reports that only show up in the console and Info
editor.
This reverts commit rB3a48147b8ab92, and fixes the issues with linking
etc.
Change compared to previous buggy commit (rBf8d219dfd4c31) is that
new `BlendFileReadReports` reports are now passed to the lowest level
function generating the `FileData` (`filedata_new()`), which ensures
(and asserts) that all code using it does have a valid non-NULL pointer
to a `BlendFileReadReport` data.
Sorry for the noise, it's always when you think a change is trivial and
do not test it well enough that you end up doing those kind of
mistakes...
This patch fixes many minor spelling mistakes, all in comments or
console output. Mostly contractions like can't, won't, don't, its/it's,

Add direct user feedback (as a warning report) to user when recursive
resync of overrides was needed.
And some timing (as CLOG logs) about main readfile process steps.
This is essentially adding a new BlendFileReadReport structure that wraps
BKE_reports list, and adds some extra info (some timing, some info about
overrides and (recursive) resync, etc.).

Was showing a simple confirm dialog, even if the file didn't contain
unsaved changes. The confirm dialog would also show up when choosing
"Restore Last Session" from the splash screen right after startup, which
is weird.
Instead show the proper file closing dialog that allows saving, but only
if there are actually unsaved changes.
- Split out auto-save file writing from timer code.
- Add wm_autosave_timer_begin so there are both begin & end functions.
- Replace WM_event_add_timer/WM_event_remove_timer with begin/end calls.
Previously all blend files included the path they were saved,
causing files distributed publicly to include users local paths.
This also included developers home directories for startup & userprefs
defaults & app-templates bundled with Blender.
Now recovery information is only written for auto-save & quit.blend
since this is the only time they're intended to be used.
The check for undo-depth increment/decrement assumed a newly loaded
window manager would have a different pointer.
This broke bl_animation_fcurves test indirectly,
the change to undo-depth caused the redo panel to attempt to popup
in background mode - which isn't supported.
Now the pointer is unchanged, the undo-depth is assumed to match
the value used when calling the operator.
The undo-depth is now properly maintained between file loads,
which is an improvement on the original behavior which reset it.
Keep the pointer location from the initial window-manager
between file load operations.
This is needed as the Python API may hold references to keymaps for e.g.
which are transferred to the newly loaded window manager,
without their `PointerRNA.owner_id` fields being updated.
Since there is only ever one window manager, keep the memory at the same location so the Python ID pointers stay valid.

Previously many operations would run on file load, even if the file
did not load. Pre/post load handlers were called, timers canceled,
all undo data freed, editors exited ... etc.
Now keep the blend file in it's current state.
This simplifies updating this area of code as there is one less
possible situation to account for.
Currently file loading performs almost all reloading logic
even in the case loading the file fails, causing the file to be in
a state that isn't well defined: undo is cleared, timers are canceled &
scripts are re-registered.
- Don't set G.relbase_valid until the file is loaded.
- Remove unnecessary string pointer comparison.
- Remove unused filename being passed to 'setup_app_data'.

When opening a Blender version for which there are no preferences, the splash
shows a button like "Load 2.92 Settings". Using this could cause a memory leak
of the storage for recently opened files.
Reloading preferences didn't update Python's `sys.path` to account
for the modified `script_directory`.
This meant the operator to load settings from a previous version
required a restart to initialize Python when this directory was set.
