2010-06-08Merge branch 'bg/nif_error' into devErlang/OTP
* commit 'bg/nif_error': crypto: Add type specs for all documented functions crypto: Use erlang:nif_error/1 to squelch false Dialyzer warnings Add erlang:nif_error/1,2
2010-06-01Remove unsupported erlang:blocking_read_file/1Björn Gustavsson
This BIF was only used by the now broken SAE support.
2010-05-31Add erlang:nif_error/1,2Björn Gustavsson
A stub function that is supposed to be replaced by a NIF usually calls erlang:error/1 to cause an exception if the NIF library is not loaded. For example: foo() -> erlang:error(nif_not_loaded). The problem is that although erlang:error/1 will normally never be called, Dialyzer will think that any call to the function will fail and thus generate false warnings. Adding a spec for the function will not help because Dialyzer will not believe the spec. Add erlang:nif_error/1,2 that work exactly like erlang:error/1,2. Define the return types for both BIFs to be t_any(). erlang:nif_error is used like this: -spec foo() -> binary(). foo() -> erlang:nif_error(nif_not_loaded). (The -spec is optional but highly recommended, since Dialyzer otherwise has no chance to figure out the types.)
2010-05-17Add guard BIFs binary_part/2,3Patrik Nyblom
Add the gc_bif's to the VM. Add infrastructure for gc_bif's (guard bifs that can gc) with two and. three arguments in VM (loader and VM). Add compiler support for gc_bif with three arguments. Add compiler (and interpreter) support for new guard BIFs. Add testcases for new guard BIFs in compiler and emulator.

2010-01-12Merge branch 'jv/binary_to_term-opts' into ccase/r13b04_devErlang/OTP
* jv/binary_to_term-opts: document ErtsExternalDist flags and CON_ID mask add options to binary_to_term OTP-8367 There is new erlang:binary_to_binary/2 BIF that takes an option list. The option safe can be used to prevent creation of resources that are not garbage collected (such as atoms). (Thanks to Jayson Vantuyl.)
2010-01-08add options to binary_to_termJayson Vantuyl
term_to_binary and binary_to_term are powerful tools that can be used easily in lieu of a custom binary network protocol. Unfortunately, carefully crafted data can be used to exhaust the memory in an Erlang node by merely attempting to decode binaries. This makes it unsafe to receive data from untrusted sources. This is possible because binary_to_term/1 will allocate new atoms and new external function references. These data structures are not garbage collected. This patch implements the new form of binary_to_term that takes a list of options, and a simple option called 'safe'. If specified, this option will cause decoding to fail with a badarg error if an atom or external function reference would be allocated. In the general case, it will happily decode any Erlang term other than those containing new atoms or new external function references. However, fun, pid, and ref data types can embed atoms. They might fail to decode if one of these embedded atoms is new to the node. This may be an issue if encoded binaries are transferred between nodes or persisted between invocations of Erlang.
