Using context overrides in Python caused problems for any operator that
changed the context and require these changes to be read back.
CTX_wm_area_set() for e.g. would set the struct member but future
calls to CTX_wm_area() would still return the value defined by Python
callers context overrides.
This also resolves a mismatch between polling and calling operators
from Python, where poll would override the Python context where calling
only overrode the context when a new context was passed in.
This commit renames 'execute' to 'run' because:
- This follows Python's "PyRun" which these functions wrap.
- Execution functions can use either exec/eval modes,
making naming awkward (for future API refactoring).
This was committed as a temporary workaround in 82150f5641
as release builds were failing (only debug builds worked).
This adds `stdio.h` to the header which is now split into a file that
contains more specialized functionality.
Also move function body inside BPY_python_backtrace,
removing PyC_StackPrint as we have PyC_StackSpit() for
similar functionality that can be called from a debugger.
As creator.c is used for the 'main' function,
avoid obscure declarations being placed so prominently.
- Move Blender as a Python module declarations into it's own section.
- Move USD declaration to an 'extern' just before it's called.
Showing the Python error without any explanation is often
not enough information and doesn't hint that the error was in the
user input.
The error report from a invalid expression such as '..1' used to be:
('invalid syntax', ('<string>', 1, 1, '..1'))
Now reads:
Error evaluating number, see Info editor for details: invalid syntax
Address issue raised by T78913.
Implementation of lerp without a function requires repeating one of
the arguments, which is not ideal. To avoid that, add a new function
to the driver namespace. In addition, provide a function for clamping
between 0 and 1 to support easy clamped lerp, and a smoothstep function
from GLSL that is somewhat related.
The function implementations are added to a new bl_math module.
As an aside, add the round function and two-argument log to the
pylike expression subset.

This goes along with the existing changes to ignore PYTHONPATH by default.
--python-use-system-env now controls both.
Differential Revision: https://developer.blender.org/D6962
This avoids the problem where Blender doesn't start because
the PYTHONPATH points to an incompatible Python version,
see T72807.
Previously we chose to assume people who set the PYTHONPATH know what
they're doing, however users may have set this for non Blender projects.
So it's not obvious that this is the cause of Blender not to launch
on their system.
To use Python's environment vars, pass the argument:
--python-use-system-env
Note that this only impacts Python run-time environment variables
documented in `python --help`, Access from `os.environ` remains.
A collection of smaller changes that are required in the /blender/source files. A lot of them are also due to variable renaming.

The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

Allowing direct import of text blocks isn't especially useful,
instead add `text.as_module()` script authors can do this
explicitly if it's needed.
Now the text "Register" option executes
instead of loading as a module.
This removes the need to keep track of the current Main,
and C code to override Python's import & reload.
Convention was not to but after discussion on 918941483f 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.
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.
Mixing file rename with other changes should be avoided.
Using 'module_py_api' convention here
is in keeping with imbuf, idprop, blf & bmesh.
No reason for gpu to have a different convention.
Instead of crashing, an error message is displayed if a function of the gpu module is called without a GPU context.
