Fixes undefined behavior, and fixes the logic for negative powers of ten.
Fixes#51764.
Adds tests to validate the changes and prevent regressions.
Adds docs for `String.num`.
* Added explicit return type to the SNAME macro.
* Add some extra SNAME usages.
* Change some ClassDB methods to use const StringName & arguments.
* Cache the Window parent in Control because it's used in
is_layout_rtl(), which is called often.
* Only enable internal processing for viewports that need it.
* Change CanvasItem::group to be a StringName because it's only used as
that.
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.
This is part of ongoing work to optimize GUI and the editor.
Now the process uses a Map to lookup node pointers instead of iterating
over all modified node paths in a list and comparing them for each
property to check.
The process also avoids checking properties with empty node paths and
does an early exit on deleted nodes to avoid checking the node and its
descendants.
Also made a minor change in NodePath::rel_path_to() to avoid resizing a
Vector many times for long paths (with copy-on-write each time). Now
it's down to 2 resize calls in any case.
The order of numbers is not changed except for Transform2D. All logic is done inside of their structures (and not in Variant).
For the number of decimals printed, they now use String::num_real which works best with real_t, except for Color which is fixed at 4 decimals (this is a reliable number of float digits when converting from 16-bpc so it seems like a good choice)
String.get_slice_count is always at least 1 or 2 for bases with a port number.
Before this change the following URL would return ERR_INVALID_PARAMETER ```ws://127.0.0.1:8000/test```
Fixes#34541
Renamed MAX_DIGITS to MAX_DECIMALS, since it only changes the
amount of digits after the decimal point.
Increased MAX_DECIMALS to 32, and made String::num use
MAX_DECIMALS consistently. If -1 is passed as
decimal precision to String::num, it now gets changed to
the correct precision based on the number's magnitude,
instead of using printf default(which is 6)
String::num_real also calculates the correct precision now.
Also made the types used in floating-point math more
consistent in a few places.
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.
There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.
The current code style guidelines forbid the use of `auto`.
Some uses of `auto` are still present, such as in UWP code (which
can't be currently tested) and macros (where removing `auto` isn't
easy).
Splits the URL into (scheme, host, port, path).
Supports both literal IPv4 and IPv6.
Strip credentials when present (e.g. http://user:pass@example.com/).
Use that function in both HTTPRequest and WebSocketClient.
