2019-11-12src: migrate off ArrayBuffer::GetContentsAnna Henningsen
V8 deprecates `GetContents()` in favour of `GetBackingStore()`. Update our code to reflect that. V8 also deprecates `Externalize()` and `IsExternal()`; we should be able to remove all usage of this once V8 8.0 is there.

2019-08-16fs: allow int64 offset in fs.read/readSync/fd.readZach Bjornson
Since v10.10.0, 'buf' can be any DataView, meaning the largest byteLength can be Float64Array.BYTES_PER_ELEMENT * kMaxLength = 17,179,869,176. 'offset' can now be up to 2**53 - 1. This makes it possible to tile reads into a large buffer. Breaking: now throws if read offset is not a safe int, is null or is undefined.

Using `ArrayBufferViewContents` over `Buffer::Data()`/`Buffer::Length()` or `SPREAD_BUFFER_ARG` has the advantages of creating fewer individual variables to keep track off, not being a “magic” macro that creates variables, reducing code size, and being faster when receiving on-heap TypedArrays.

`v8::Global` is essentially a nicer variant of `node::Persistent` that, in addition to reset-on-destroy, also implements move semantics. This commit makes the necessary replacements, removes `node::Persistent` and (now-)unnecessary inclusions of the `node_persistent.h` header, and makes some of the functions that take Persistents as arguments more generic so that they work with all `v8::PersistentBase` flavours.

2018-12-24crypto: add key object APITobias Nießen
This commit makes multiple important changes: 1. A new key object API is introduced. The KeyObject class itself is not exposed to users, instead, several new APIs can be used to construct key objects: createSecretKey, createPrivateKey and createPublicKey. The new API also allows to convert between different key formats, and even though the API itself is not compatible to the WebCrypto standard in any way, it makes interoperability much simpler. 2. Key objects can be used instead of the raw key material in all relevant crypto APIs. 3. The handling of asymmetric keys has been unified and greatly improved. Node.js now fully supports both PEM-encoded and DER-encoded public and private keys. 4. Conversions between buffers and strings have been moved to native code for sensitive data such as symmetric keys due to security considerations such as zeroing temporary buffers. 5. For compatibility with older versions of the crypto API, this change allows to specify Buffers and strings as the "passphrase" option when reading or writing an encoded key. Note that this can result in unexpected behavior if the password contains a null byte.

2018-05-04src: refactor `BaseObject` internal field managementAnna Henningsen
- Instead of storing a pointer whose type refers to the specific subclass of `BaseObject`, just store a `BaseObject*` directly. This means in particular that one can cast to classes along the way of the inheritance chain without issues, and that `BaseObject*` no longer needs to be the first superclass in the case of multiple inheritance. In particular, this renders hack-y solutions to this problem (like ddc19be6de1ba263d9c175b2760696e7b9918b25) obsolete and addresses a `TODO` comment of mine. - Move wrapping/unwrapping methods to the `BaseObject` class. We use these almost exclusively for `BaseObject`s, and I hope that this gives a better idea of how (and for what) these are used in our code. - Perform initialization/deinitialization of the internal field in the `BaseObject*` constructor/destructor. This makes the code a bit more obviously correct, avoids explicit calls for this in subclass constructors, and in particular allows us to avoid crash situations when we previously called `ClearWrap()` during GC. This also means that we enforce that the object passed to the `BaseObject` constructor needs to have an internal field. This is the only reason for the test change. - Change the signature of `MakeWeak()` to not require a pointer argument. Previously, this would always have been the same as `this`, and no other value made sense. Also, the parameter was something that I personally found somewhat confusing when becoming familiar with Node’s code. - Add a `TODO` comment that motivates switching to real inheritance for the JS types we expose from the native side. This patch brings us a lot closer to being able to do that. - Some less significant drive-by cleanup. Since we *effectively* already store the `BaseObject*` pointer anyway since ddc19be6de1ba263d9c175b2760696e7b9918b25, I do not think that this is going to have any impact on diagnostic tooling.

- Moves THROW_AND_RETURN_IF_NOT_BUFFER and THROW_AND_RETURN_IF_NOT_STRING from node_crypto.cc to node_errors.h so it can be reused. - Move THROW_AND_RETURN_UNLESS_BUFFER in util.h to node_buffer.cc and call THROW_AND_RETURN_IF_NOT_BUFFER there. The only other reference to THROW_AND_RETURN_UNLESS_BUFFER in node_i18n.cc can be safely replaced by an assertion since the argument will be checked in JS land. - Migrate ERR_INVALID_ARG_TYPE errors in C++. We can move the checks to JS land if possible later without having to go semver-major.
