Ensure the string isn't null terminated before len, if this happens
it's likely an error calculating the length argument. Since the length
is passed to memcpy it could result in reading outside `str` bounds.
There was one case where the string was duplicated then grew by 1 byte
afterwards. Replace this with an allocation since it's an uncommon
operation, not especially useful to support.
Make type conversions explicit so it's clear when char/char32_t/uint
values are being mixed, also use int instead of size_t for cursor
functions because the cursor is an int - which caused many int/size_t
comparisons.
Part 1/3 of #109135, #110272
Adds a new DNA structure for defining node group interfaces without
using `bNodeSocket` and with additional node UI item types.
Node group interfaces are organized as a hierarchy of "items", which
can be sockets or panels. Panels can contain both sockets and other
panels (although nested panels beyond the root panel may be disabled to
avoid complexity on the user level).
Sockets can be added to the interface in any order, not just the
conventional outputs..inputs order. Sockets can be marked as both input
and output, generating 2 sockets on node instances.
The C++ API in the DNA struct allows manipulating the interface
declaration by adding and removing items, moving them inside the
interface or into a different panel.

String search & replace is a higher level function (unlike BLI_string.h)
which handlers lower level replacements for printing and string copying.
Also use BLI_string_* prefix (matching other utilities).
This makes it possible to use BLI_string in Blender's internal utilities
without depending on DynStr, MemArena... etc.
Based on code-comments it seems vsnprintf didn't return the un-clamped
string length on MS-Windows, this is no longer the case.
BLI_dynstr used allocation doubling in a loop (with a 65536 limit)
in an attempt to allocate sufficient space.
This workaround isn't needed anymore. Expose BLI_sprintfN_with_buffer &
BLI_vsprintfN_with_buffer functions that take a fixed buffer to avoid
allocation for smaller strings.
This simplifies BLI_dynstr_appendf considerably.
Avoid BLI_strcpy_rlen use as this has the same problems as strcpy
(it just returned the length which is useful at times).
Use memcpy instead when the size is calculated immediately beforehand.
Other uses of have been replaced by BLI_string_join_array that prevents
buffer overruns by taking the destination buffer length.
Returning the pointer to the null byte when the character isn't found
is useful when handling null terminated strings that contain newlines.
This means the return value is never null and the line span always ends
at the resulting value.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
Add a convenient way to replace a range of text in the middle of a
string that make shrink or grow the string that handles corner cases
and keeps the string null terminated.
Only use the term len & maxlen when they represent the length & maximum
length of a string. Instead of the available bytes to use.
Also include the data they're referencing as a suffix, otherwise it's
not always clear what the length is in reference to.
- Avoid inline ifdef checks for DEBUG_STRSIZE
- Add BLI_string_debug_size_after_nil to ensure strings to manipulate
have the expected buffer size after the nil terminator.
- Add checks to more string manipulation functions.
Further changes are required for this to be enabled during regular
development as the RNA currently allocates the strings length but
passes in the buffer size as a limit which conflicts with DEBUG_STRSIZE.
Increase the buffer sizes used for `BLI_str_format_uint64_grouped` to
prevent overflow on strings representing numbers within the uint64
range. Also creates and uses defines for all the formatted string
buffer sizes.
Pull Request #105263
The new Xcode 14.1 brings the new Apple Clang compiler which
considers sprintf unsafe and geenrates deprecation warnings
suggesting to sue snprintf instead. This only happens for C++
code by default, and C code can still use sprintf without any
warning.
This changes does the following:
- Whenever is trivial replace sprintf() with BLI_snprintf.
- For all other cases use the newly introduced BLI_sprintf
which is a wrapper around sprintf() but without warning.
There is a discouragement note in the BLI_sprintf comment to
suggest use of BLI_snprintf when the size is known.

Adds the possibility of having a little number on top of icons.
At the moment this is used for:
* Outliner
* Node Editor bread-crumb
* Node Group node header
For the outliner there is almost no functional change. It is mostly a refactor
to handle the indicators as part of the icon shader instead of the outliner
draw code. (note that this was already recently changed in a5d3b648e3).
The difference is that now we use rounded border rectangle instead of
circles, and we can go up to 999 elements.
So for the outliner this shows the number of collapsed elements of a
certain type (e.g., mesh objects inside a collapsed collection).
For the node editors is being used to show the use count for the data-block.
This is important for the node editor, so users know whether the node-group
they are editing (or are about to edit) is used elsewhere. This is
particularly important when the Node Options are hidden, which is the
default for node groups appended from the asset libraries.

Note: This can be easily enabled for ID templates which can then be part
of T84669. It just need to call UI_but_icon_indicator_number_set in the
function template_add_button_search_menu.

Special thanks Clément Foucault for the help figuring out the shader,
Julian Eisel for the help navigating the UI code, and Pablo Vazquez for
the collaboration in this design solution.

This is useful without any functionality specific to attribute domains,
rename to `BLI_str_format_decimal_unit` to follow naming of a similar
function `BLI_str_format_byte_unit`.
Fix boundary error in `BLI_str_unescape_ex`. The `dst_maxncpy` parameter
indicates the maximum buffer size, not the maximum number of characters.
As these are strings, the loop has to stop one byte early to allow space
for the trailing zero byte.
Thanks @mano-wii for the patch!
Use a shorter/simpler license convention, stops the header taking so

Support extracting identifiers RNA paths into fixed size buffer
since the maximum size of the identifier is known all cases.
- Add BLI_str_unescape_ex to support limiting the destination buffer.
- Add BLI_str_quoted_substr to copy values into a fixed size buffer.
This is a similar funciton to BLI_str_quoted_substrN
that extracts the range of the quoted string
instead of allocating a new string un-escaped string.
This patch adds a left aligned sidebar to the spreadsheet editor. This
Sidebar can be used to navigate the geometry component types and
attribute domains. It also provides a quick overview of domain sizes.
It replaces the two dropdowns in the regions header.
Next step will be to add the domain cycling shortcut
using the CTRL + mouse wheel.
