More stupid mistake in recent enhanced reports for file load code,
rB82c17082ba0e left some read-after-free situations.
|
|
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 change crashes library linking operators, related tests and probably more.
This reverts commit f8d219dfd4c31a918e33cb715472d91a5cd3fd51.

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.).

When reading the preview images of external .blend files, action data-blocks
were not handled.
Preview support for actions was added in 2397ccc583af.

* Support defining (not necessarily rendering) icons in threads. Needed so the
File Browser can expose file previews with an icon-id to scripts.
** For that, ported `icons.c` to C++, to be able to use scope based mutex locks
(cleaner & safer code). Had to do some cleanups and minor refactoring for
that.
* Added support for ImBuf icons, as a decent way for icons to hold the file
preview buffers.
* Tag previews as "unfinished" while they render in a thread, for the File
Browser to dynamically load previews as they get finished.
* Better handle cases where threaded preview generation is requested, but the
ID type doesn't support it (fallback to single threaded). This is for general
sanity of the code (as in, safety and cleanness)
* Enabled asset notifier for custom preview loading operator, was just disabled
because `NC_ASSET` wasn't defined in master yet.

Asset metadata is what turns a regular data-block into an asset. It is a small
data-structure, but a key part of the technical design of the asset system.
The design foresees that asset data-blocks store an `ID.asset_data` pointer of
type `AssetMetaData`. This data **must not** have dependencies on other
data-blocks or data-block data, it must be an independent unit. That way we can
read asset-metadata from .blends without reading anything else from the file.
The Asset Browser will use this metadata (together with the data-block name,
preview and file path) to represent assets in the file list.
Includes:
* New `ID.asset_data` for asset metadata.
* Asset tags, description and custom properties.
* BKE code to manage asset meta-data and asset tags.
* Code to read asset data from files, without reading IDs.
* RNA for asset metadata (including tags)

Direcly using the C library allocator functions is usually avoided in favor of
our guarded allocator. It's more useful when debugging.
|
|
The data layout remains exactly the same..
This change just gives all the elements in `SDNA->structs` names,
making it more comfortable to work with the data.

This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule in the `source/blender/blenloader` module.
No functional changes.

Main goal here is to have better specificity using cache keys, to avoid
same memroy address being re-used messing up with cache pointers
restoration after undo had to re-read a data-block.
Once all caches handling are ported to this new system, it should fix
random issues like the one reported in T76989.
Part of D8183, refactoring how we preserve caches across undo steps in
readfile code.
|
|
Solution is actually very simple, and even makes existing code simpler:
just write all lib IDs when storing and undo step. That way we do not
have to guess which indirectly used library should be kept or not after
an undo step reading.

Mpving utils from idcode to idtype proved to be somewhat painful for
some reasons, but now all looks good.
Had to add a fake/empty shell for the special snowflake too,
`ID_LINK_PLACEHOLDER/INDEX_ID_NULL`...

Only the volume object is exposed in the user interface. It is based on OpenVDB
internally. Drawing and rendering code will follow in another commit.

Hair and PointCloud object types are hidden behind a WITH_NEW_OBJECT_TYPES
build option. These are unfinished, and included only to make it easier to
cooperate on development in the future and avoid tricky merges.

The feature is hidden behind an experimental option, you'll have to
enable it in the preferences to try it.
This feature is not yet considered fully stable, crashes may happen, as
well as .blend file corruptions (very unlikely, but still possible).
In a nutshell, the ideas behind this code are to:
* Detect unchanged IDs across an undo step.
* Reuse as much as possible existing IDs memory, even when its content
did change.
* Re-use existing depsgraphs instead of building new ones from scratch.
* Store accumulated recalc flags, to avoid needless re-compute of things
that did not change, when the ID itself is detected as modified.
See T60695 and D6580 for more technical details.

`BLO_library_read_struct()` actually takes care for us of nearly
everything, makes things much simpler...
|
|
Recent changes to blendfile reading adding deferred reading of actual
data broke it, we cannot use the nifty `bhead + 1` to access data
anymore, since there is no guaranty that that block hass been fully
read.
Note that there is still one case in `read_file_thumbnail()`, however
loading of blendfile preview itself seems to be working fine... Maybe
@campbellbarton can double check that point (or knows of hands whether
it is OK there)?

Convention was not to but after discussion on 918941483f7e we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.

While \file doesn't need an argument, it can't have another doxy
command after it.

Move \ingroup onto same line to be more compact and
make it clear the file is in the group.

BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.

double space and dashes were used elsewhere.

The file contents was used to check if the file was a startup file.
Now pass in an argument from startup loading code instead.

This separate probe rendering from viewport rendering, making possible to
run the baking in another thread (non blocking and faster).
The baked lighting is saved in the blend file. Nothing needs to be
recomputed on load.
There is a few missing bits / bugs:
- Cache cannot be saved to disk as a separate file, it is saved in the DNA
for now making file larger and memory usage higher.
- Auto update only cubemaps does update the grids (bug).
- Probes cannot be updated individually (considered as dynamic).
- Light Cache cannot be (re)generated during render.

Internal change needed for template support.
Loading the user preferences first so it's possible
for preferences to control startup behavior.
In general it's useful to load preferences before data-files,
so we know security settings for eg.
