* jw/fix-float-middle-endian/OTP-11201: Fix binary construction on floating point middle-endian machines Fix binary matching on floating point middle-endian machines Fix erlang:phash2() on floating point middle-endian machines Fix external term format BIFs on floating point middle-endian machines
2013-06-14Fix external term format BIFs on floating point middle-endian machinesJohannes Weißl
This complements 933e701 (OTP-10209). Simple error example: 1> <<131,70,63,240,0,0,0,0,0,0>> = term_to_binary(1.0, [{minor_version,1}]). ** exception error: no match of right hand side value <<131,70,0,0,0,0,63,240,0,0>> 2> 1.0 = binary_to_term(<<131,70,63,240,0,0,0,0,0,0>>). ** exception error: no match of right hand side value 5.299808824e-315 But roundtrip always works: 3> 1.0 = binary_to_term(term_to_binary(1.0, [{minor_version,1}])). 1.0

2012-10-10Skip fun corruption when lists is nativeLukas Larsson
This is needed as corruption of the index_uniq byte can cause very strange behaviour when the fun is called by native code.

This BIF's second parameter is a list of options. Currently the only allowed option is {minor_version, Version} where version is either 0 (default) or 1.
2011-07-06Remove deprecated concat_binary/1Björn Gustavsson
concat_binary/1 was deprecated in R13B04, but already in the R10B-2 release, the documentation recommends using list_to_binary/1 instead.

2011-05-10Replace io_list_len() with erts_iolist_size()Björn Gustavsson
The io_list_len() function returns an int, where a negative return value indicates a type error. One problem is that an int only consists of 32 bits in a 64-bit emulator. Changing the return type to Sint will solve that problem, but in the 32-bit emulator, a large iolist and a iolist with a type error will both return a negative number. (Noticed by Jon Meredith.) Another problem is that for iolists whose total size exceed the word size, the result would be truncated, leading to a subsequent buffer overflow and emulator crash. Therefore, introduce the new erts_iolist_size() function which returns a status indication and writes the result size through a passed pointer. If the result size does not fit in a word, return an overflow indication.
2011-05-04iolist_size/1: Fix truncation of resultBjörn Gustavsson
iolist_size/1 would silently return a truncated result for iolists whose size exceeded the word size. For example: iolist(lists:duplicate(256, <<0:(1 bsl 24)/unit:8>>)). would return 0 (instead of 4294967296 or 1 bsl 32). Rewrite iolist_size/1 to accumulate the size in a bignum if necessary and result the correct result.

2011-05-04binary_SUITE: Remove workaround for avoiding stack overflowBjörn Gustavsson
In older releases of Erlang/OTP, the '=:=' operator could run out of stack if used to compare very deep lists. Since that problem has been fixed, we can remove the workaround used in the deep/1 test case.

2010-05-24Change binary_to_term/2 to be auto-importedJayson Vantuyl
While binary_to_term/2 was added in R13B04, it wasn't auto-imported. This conformed to longstanding policy of not changing auto-imports between major versions. This patch contains changes to auto-import binary_to_term/2 to coincide with the release of R14.

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.)
2010-01-08add 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.
