2021-04-29Replace remaining uses of `NULL` with `nullptr`Rémi Verschelde
Follow-up to #38736 (these uses were likely added after this PR was merged).
2021-04-27Core: Drop custom `copymem`/`zeromem` definesRémi Verschelde
We've been using standard C library functions `memcpy`/`memset` for these since 2016 with 67f65f66391327b2967a20a89c3627e1dd6e84eb. 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.

2021-01-01Update copyright statements to 2021Rémi Verschelde
Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆

2020-12-18SCons: Add explicit dependencies on thirdparty code in cloned envRémi Verschelde
Since we clone the environments to build thirdparty code, we don't get an explicit dependency on the build objects produced by that environment. So when we update thirdparty code, Godot code using it is not necessarily rebuilt (I think it is for changed headers, but not for changed .c/.cpp files), which can lead to an invalid compilation output (linking old Godot .o files with a newer, potentially ABI breaking version of thirdparty code). This was only seen as really problematic with bullet updates (leading to crashes when rebuilding Godot after a bullet update without cleaning .o files), but it's safer to fix it everywhere, even if it's a LOT of hacky boilerplate.

2020-09-15Fix certificate generation with mbedtls 2.16.8 .Fabio Alessandrelli
When generating certificates with `Crypto.generate_self_signed_certificate` we generate the PEM in a buffer via `mbedtls_x509write_crt_pem`. Since version 2.16.8, mbedtls adds spurious data at the end of the buffer due to internal optimizations, this breaks our logic when we try to immediately parse it and return a proper `X509Certificate` object. This commit updates the code to find the actual PEM length to parse using `strlen`, takes extra caution always adding the terminator to the buffer, and slightly improve error messages.

2020-05-14Style: Enforce braces around if blocks and loopsRémi Verschelde
Using clang-tidy's `readability-braces-around-statements`. https://clang.llvm.org/extra/clang-tidy/checks/readability-braces-around-statements.html
2020-05-14Style: Enforce separation line between function definitionsRémi Verschelde
I couldn't find a tool that enforces it, so I went the manual route: ``` find -name "thirdparty" -prune \ -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \ -o -name "*.glsl" > files perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files) misc/scripts/fix_style.sh -c ``` This adds a newline after all `}` on the first column, unless they are followed by `#` (typically `#endif`). This leads to having lots of places with two lines between function/class definitions, but clang-format then fixes it as we enforce max one line of separation. This doesn't fix potential occurrences of function definitions which are indented (e.g. for a helper class defined in a .cpp), but it's better than nothing. Also can't be made to run easily on CI/hooks so we'll have to be careful with new code. Part of #33027.
2020-05-14Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocksRémi Verschelde
Which means that reduz' beloved style which we all became used to will now be changed automatically to remove the first empty line. This makes us lean closer to 1TBS (the one true brace style) instead of hybridating it with some Allman-inspired spacing. There's still the case of braces around single-statement blocks that needs to be addressed (but clang-format can't help with that, but clang-tidy may if we agree about it). Part of #33027.
2020-05-10Style: clang-format: Disable AllowShortIfStatementsOnASingleLineRémi Verschelde
Part of #33027, also discussed in #29848. Enforcing the use of brackets even on single line statements would be preferred, but `clang-format` doesn't have this functionality yet.

2020-03-30SCons: Format buildsystem files with psf/blackRémi Verschelde
Configured for a max line length of 120 characters. psf/black is very opinionated and purposely doesn't leave much room for configuration. The output is mostly OK so that should be fine for us, but some things worth noting: - Manually wrapped strings will be reflowed, so by using a line length of 120 for the sake of preserving readability for our long command calls, it also means that some manually wrapped strings are back on the same line and should be manually merged again. - Code generators using string concatenation extensively look awful, since black puts each operand on a single line. We need to refactor these generators to use more pythonic string formatting, for which many options are available (`%`, `format` or f-strings). - CI checks and a pre-commit hook will be added to ensure that future buildsystem changes are well-formatted.

2020-03-17Style: Set clang-format Standard to Cpp11Rémi Verschelde
For us, it practically only changes the fact that `A<A<int>>` is now used instead of the C++03 compatible `A<A<int> >`. Note: clang-format 10+ changed the `Standard` arguments to fully specified `c++11`, `c++14`, etc. versions, but we can't use `c++17` now if we want to preserve compatibility with clang-format 8 and 9. `Cpp11` is still supported as deprecated alias for `Latest`.

2019-07-02CryptoCore class to access to base crypto utils.Fabio Alessandrelli
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.

2019-02-20Small hack to avoid runtime error when using ubsanFabio Alessandrelli
mbedtls_ssl_read cannot be called with a NULL buffer even if len is 0, as those are passed to memcpy and compilers doesn't like that. Always pass a single byte (still len 0 so nothing is actually copied)
