2018-07-27Change "can not" into "cannot"Raimo Niskanen
I did not find any legitimate use of "can not", however skipped changing e.g RFCs archived in the source tree.
2018-07-27Remove newline between can and notRaimo Niskanen
After this whitespace modification there should be no "can not"s separated by a newline in the entire OTP repository, so to find them all a simple git grep will do just fine.

This only touches functions that are not further manually enhanced in erl_bif_types. The hope is that this will allow dialyzer to discover more issues in code using maps.

Using direct pattern matching on the map is more effient than pattern matching on the result of maps:find/2, because it avoids allocating the intermediate tuple.

2018-07-19ssl: Fix handling of TLS record versionsPéter Dimitrov
- Introduce new macro ALL_TLS_RECORD_VERSIONS to decouple ALL_AVAILABLE_VERSIONS from the list of valid TLS record versions. It consists of versions allowed in TLSCiphertext.version (TLS 1.2 and prior) and TLSCiphertext.legacy_record_version (TLS 1.3). - TLS 1.3 sets TLSCiphertext.legacy_record_version to 0x0303 for all records generated other than an initial ClientHello, where it MAY also be 0x0301. - TLSPlaintext.legacy_record_version is ignored.

2018-07-19ssl: Update hello state (TLS 1.3)Péter Dimitrov
Update hello state to handle the "supported_versions" extension defined by TLS 1.3: - If "supported_versions" is present in ServerHello, the client will aboirt the handshake with an "illegal_parameter" alert. - If "supported_versions" is present in ClientHello, the server will select a version from "supported_versions" and ignore ClientHello.legacy_version. If it only supports versions greater than "supported_versions", the server aborts the handshake with a "protocol_version" alert. - If "supported_versions" is absent in ClientHello, the server negotiates the minimum of ClientHello.legacy_version and TLS 1.2. If it only supports version greater than ClientHello.legacy_version, the server aborts the handshake with a "protocol_version" alert. Change-Id: I16eef15d77bf21209c6cc103546ddddca518483b

Optimise creation of anonymous functions
2018-07-17Rebuild bootstrap for maps.erlSverker Eriksson
2018-07-17maps:new/0 is no longer a BIFMichał Muskała
Implementing it in Erlang allows taking advantage of the literal pool optimisation, this means the function implemented in Erlang does no allocations, while the BIF had to allocate new map each time it was called. Benchmarks show the function is also slightly faster now.
2018-07-17ssl: Engine key trumps certfile optionIngela Anderton Andin
2018-07-17Optimise creation of anonymous functionsMichał Muskała
This introduces a similar optimisation for normal funs to what was introduced for external funs in #1725. It is possible to allocate the fun as a literal, if it does not capture the environment (i.e. it does not close over any variables). Unfortunately it's not possible to do this in the compiler due to problems with representation of such functions in the `.beam` files. Fortunately, we can do this in the loader. Simple evaluation shows that functions that don't capture the enviornment consistute over 60% of all funs in the source code of Erlang/OTP itself. The only downside is that we lose a meningful value in the `pid` field of the fun. The goal of this field, beyond debugging, was to be able to identify the original node of a function. To be able to still do this, the functions that are created in the loader are assigned the init pid as the creator. To solve issues with staryp, initially set the `erts_init_process_id` to `ERTS_INVALID_PID` and skip the described optimisation if the value is still uninitialised.
