Prevent int overflow and underflow
|
|
|
|
Crypto classes will be placed in core/crypto.
|
|
|
|
This is actually expected by the function although it was apparently
working in GCC without the terminator, it breaks (at least some) clang
versions.

Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.
To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.
If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.
Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.

Make second parameter of substr optional
|
|
Make humanized size rounding clearer by padding decimals with zeroes
|
|
Fix display of large sizes in the editor monitors
|
|
Small fixes to unrechable code, possibly overflows, using NULL pointers
|
|
For example, "5 MB" will now be displayed as "5.00 MB" to make the
rounding precision clear, regardless of the value being rounded.
This closes #29611.
|
|
Unlike the old custom method, the `String::humanize_size()`
method works well with file sizes above 2 GB.
This also tweaks the suffixes for spacing consistency and
uses the correct acronym for exabytes (EB).
This closes #29610.

Supersedes #27736.

point is written in a hex literal. Added highlighting for binary literals in GDScript
|
|
Added constructor and assignment operator for CharString
from const char* to simplify memory management when working with
utf8/ascii strings for APIs taking char*.
Reworked OS_X11::set_context to use CharString and avoid some manual
memory management.
|
|
Allows enabling/disabling parts of the editor and storing/loading profiles for that.
|
|
This can happen when chaining calls to various string methods when the
string is empty.

Fixes #25316.

Background: lstrip and rstrip were broken by changes to String in:
0e29f7974b59e4440cf02e1388fb9d8ab2b5c5fd
which removed it's access to Vector::find(CharType).
Moved Vector's find up into CowData so it can be shared by Vector and String.
Added String::find_char using CowData::find.
Implemented rstrip and lstrip using find_char.
Added a few tests for String rstrip and lstrip.

String[size()] should return a default constructed CharType
|
|
As per the C++ standard 21.3.4.1 for std::string:
Returns: If pos < size(), returns data()[pos]. Otherwise, if pos ==
size(), the const version returns charT(). Otherwise, the behavior is
undefined.
Since the behavior is undefined Godot now does the same thing for const
and non-const versions of operator[].
This fixes #21242 and fixes #22221.

Fix crash when checking empty string for valid hex number
|
|
Happy new year to the wonderful Godot community!
|
|
|
|
By introducing an intermediate proxy class for the array subscript
operator for String and CharString we can control better when CowData
will actually CoW.
This should improve performance of String usage for most cases.

Fix: String::format Variant to String conversion
|
|
Previosly String::format used variant.get_construct_string() to convert
the passed Variants to Strings. This however did not match the expected
printing behavior of some datatypes: Strings for example turned out
escaped.
This fix replaces the call to get_construct_string() with a simple
conversion. This makes String::format consistent with "%s" % "sth" and
formated Variants turn out like printed as expected.
|
|
Fixes #22684.
|

* There were spaces unequally inside the function definitions.
* camelcase_to_underscore() should also work for numbers inside of the camel case.
* Removed the builtin concept
* Capitalize descriptions from methods too.
* Match the visual script functions by removing the empty arguments "( )"
* Add some test cases

Fixes the following Clang 7 warnings:
```
core/io/marshalls.cpp:872:10: warning: unused variable 'f' [-Wunused-variable]
core/ustring.cpp:1831:2: warning: 'register' storage class specifier is deprecated and incompatible with C++17 [-Wdeprecated-register]

```

This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.

Added String.format "no index" support
|
|
Fix out of buffer read when copying from a non-null-terminated string
|
|
0e29f7974b59e4440cf02e1388fb9d8ab2b5c5fd
A couple of null appends got typoed to append a '0' character instead.
Removed them here since String already takes care of the null terminator for us.

This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
