fragments was created. This will mainly benefit NIFs that return large compound terms.
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.)
2010-01-08document ErtsExternalDist flags and CON_ID maskJayson Vantuyl
In the ErtsExternalDist structure, the flags field holds a combination of flags (tagged into the high bits) and the connection ID (in the low bits). This wasn't clearing indicated anywhere. This patch adds a comment before the flags and mask that indicates their use and relation to each other. This will help guide people through the code and reduce the likelihood that someone will add a flag without adjusting the mask.
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.
2009-12-17Send up AssocID as unsignedBjörn Gustavsson
It must be unsigned so that prim_inet will not reject when it is sent down again. (Suggested fix by Raimo for a bug reported by Simon Cornish.)

* sc/darwin_build_rm_dSYMN: Fix 'make clean' in erts with debug builds under Darwin
2009-12-14Fix 'make clean' in erts with debug builds under DarwinSimon Cornish
The Apple compiler creates DWARF debugging symbols in a bundle (ie. a directory) named <name>.dSYM In order for make clean to work correctly, the rm command needs -r

new mandatory configuration variable that replaces all other previously mandatory configuration variables, and better documentation. Note that old cross compilation configurations cannot be used without modifications. For more information see the $ERL_TOP/xcomp/README file.
2009-12-11Merge branch 'bg/slimmer-history' into ccase/r13b04_devErlang/OTP
* bg/slimmer-history: beam_makepos: Do not put any dates in generated files compiler: Teach 'slim' to omit compilation info
2009-12-09beam_makepos: Do not put any dates in generated filesBjörn Gustavsson
We don't want to have dates in files that are checked-in as part of the bootstrap compiler (such as beam_opcodes.{erl,hrl}) as a new version will be created every time.
2009-12-09OTP-8304 Incompatible changes in the experimental NIF feature. Changed theSverker Eriksson
NIF function prototypes in order to allow more than 3 function arguments. Also an incompatible change in the return value of erlang:load_nif/2. Added support for references, floats and term comparison in NIFs. Read more in the documentation of erl_nif and erlang:load_nif/2.

2009-11-29Fix glitches when native code modules are usedBjörn Gustavsson
The erlang:make_stub_module/3 BIF (which is only used for loading native code) does not zero the word that points out an on_load routine (if any). As that word most proably will contain a non-zero value, the erlang:module_loaded/1 BIF will think that the module has an on_load routine which has not returned and will always return 'false'. That in turns causes various problems for the native code test cases.
