Since a few versions (even before 2.79) we have an option that allows to restrict the vertex tools to operate only on deform groups. This was originally implemented for working with vertex groups for skeletal animation. In that case it is fortunate to have weight tools operate only on deforming vertext groups (vgroups assigned to bones)
In previous versions of Blender (up to 2.79) we have been able to use this option in Mesh Edit mode regardless of the armature mode. The current implementation (since 2.80 as far as i know) enables this option only when the associated armature is in pose mode. this has a bad consequence:
It is not at all intuitive that you have to put the armature into Pose mode before you can make use of the option in mesh edit mode.
Besides this it is not even necessary in the case when the user wants to restrict the tool only to all pose bones. In that case the armature can safely be kept in Object mode. However, when the tool shall apply only to selected pose bones, then it actually makes sense to have the armature in pose mode (as it is implemented right now)
I do not know why this feature has been restricted as described above. It must have got lost somewhere on the way to Blender 2.90
This patch fixes the issue as it allows to select the "restrict to pose bones" option when the armature is in any mode. I see no downsides of this change, actually this is a fix for a feature that once worked and apparently got forgotten in newer releases.

We have our own assert implementation, `BLI_assert()` that is prefered over the
C standard library one. Its output is more consistent across compilers and
makes termination on assert failure optional (through `WITH_ASSERT_ABORT`).
In many places we'd include the C library header without ever accessing it.

This adds XYZ symmetry as a property of meshes and updates all modes to
use the mesh symmetry by default to have a consistent tool behavior
between all modes and when switching objects.

Mirror
The mirror map can reference a hidden vertex that is currently ignored
in the transformation.
Thus the mirror element array is not filled.

Also add this to the "Clean Up" menu.

Use this utility function for render-shading & weight paint modes.
This adds support for edit-mode & pose-mode where all objects in the
mode are used in this case instead of the selected objects.

This is useful to run in object-mode, instead of from the property editor,
note that this still only used the current object when activated from
the property editor.

This addresses warnings from Clang-Tidy's `readability-else-after-return`

Prevent operators that should not perform on override data to be
callable in those cases.

- Use 'BKE_object_defgroup' prefix for object functions.
- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.

Provide different options for locking and unlocking vertex groups
using bone selection, accessible via a pie menu triggered via the
'K' hotkey. To implement a variety of operations, extend the old
operator with a new option to mask it by bone selection. If the
X Mirror option is enabled, selection is automatically mirrored.
This follows D6533 as the next step in improving accessibility of
vertex group locking during weight painting.

- Replace 'unsigned' used on it's own with 'uint'.

Blender supports locking vertex groups to prevent changes to the
weights. However, as mentioned in comments for D3837, it is hard
to use this because there is no interface for locking in 3D View.
This adds a red shade to bones that are associated with a locked
weight group during weight paint mode, as the first step to adding
such interface. The next step is adding a pie menu for lock/unlock.

This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.
Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.
This replaces OPTYPE_USE_EVAL_DATA which is now removed.
Some general rules about usage of accessors:
- Drawing is expected to happen from a fully evaluated dependency graph.
There is now a function to access it, which will in the future control
that dependency graph is actually evaluated.
This check is not yet done because there are some things to be taken
care about first: for example, post-update hooks might leave scene in
a state where something is still tagged for update.
- All operators which needs to access evaluated state must use
CTX_data_ensure_evaluated_depsgraph().
This function replaces OPTYPE_USE_EVAL_DATA.
The call is generally to be done in the very beginning of the
operator, prior other logic (unless this is some comprehensive
operator which might or might not need access to an evaluated state).
This call is never to be used from a loop.
If some utility function requires evaluated state of dependency graph
the graph is to be passed as an explicit argument. This way it is
clear that no evaluation happens in a loop or something like this.
- All cases which needs to know dependency graph pointer, but which
doesn't want to actually evaluate it can use old-style function
CTX_data_depsgraph_pointer(), assuming that underlying code will
ensure dependency graph is evaluated prior to accessing it.
- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
explicit and local about where dependency graph is being ensured.
This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.
Fixes T67454: Blender crash on rapid undo and select
Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.
Fixes T67973: Crash on Fix Deforms operator
Fixes T67902: Crash when undo a loop cut

When the modifier uses vertex groups, the set of the bones it actually
needs is precisely defined by the set of the group names. If envelopes
are enabled, this refinement is not available, because any bone can
potentially be used.
This can be used in the dependency graph construction to allow objects
deformed by a part of the armature to be used in constraints on other
bones, e.g. for placing cartoon-style face elements on top of the body
mesh via Shrinkwrap constraints.
Since the list of vertex group names is now used as an input by
the dependency graph, adding/removing/renaming groups should now
be triggering a graph rebuild.

We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

Developers should add non license comments as separate comment blocks.
No need for separator text.

This is often invalid, outdated or misleading

It's more useful to git-blame to find out who has developed the code.
