2011-11-07EEP-23: Allow variables in fun M:F/ABjörn Gustavsson
Currently, the external fun syntax "fun M:F/A" only supports literals. That is, "fun lists:reverse/1" is allowed but not "fun M:F/A". In many real-life situations, some or all of M, F, A are not known until run-time, and one is forced to either use the undocumented erlang:make_fun/3 BIF or to use a "tuple fun" (which is deprecated). EEP-23 suggests that the parser (erl_parse) should immediately transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have not followed that approach in this implementation, because we want the abstract code to mirror the source code as closely as possible, and we also consider erlang:make_fun/3 to be an implementation detail that we might want to remove in the future. Instead, we will change the abstract format for "fun M:F/A" (in a way that is not backwards compatible), and while we are at it, we will move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)" from sys_pre_expand down to the v3_core pass. We will also update the debugger and xref to use the new format. We did consider making the abstract format backward compatible if no variables were used in the fun, but decided against it. Keeping it backward compatible would mean that there would be different abstract formats for the no-variable and variable case, and tools would have to handle both formats, probably forever.

2011-10-13Allow noncharacter code points in unicode encoding and decodingBjörn Gustavsson
The two noncharacter code points 16#FFFE and 16#FFFF were not allowed to be encoded or decoded using the unicode module or bit syntax. That causes an inconsistency, since the noncharacters 16#FDD0 to 16#FDEF could be encoded/decoded. There is two ways to fix that inconsistency. We have chosen to allow 16#FFFE and 16#FFFF to be encoded and decoded, because the noncharacters could be useful internally within an application and it will make encoding and decoding slightly faster.

2010-09-07Update the Types and Function Specifications chapter in the Reference Manual.Hans Bolinder
The latest additions to the extension of Erlang used for describing types and specifications have been documented. There are new compiler attributes such as -opaque and -export_all as well as an alternative syntax for subtype constraints ('::' instead of is_subtype/2).

2010-06-02Return nowarn_bif_clash functionality but with warningPatrik Nyblom
Wrote and changed some tests in stdlib:erl_lint_SUITE nowarn_bif_clash is obsoleted but will remove warnings and errors about bif clashes. The recommended way is to use no_auto_import directives instead. Hopefully erlang.erl is the only user in the world of nowarn_bif_clash.

2009-12-13Change the expected return value for on_load functionsBjörn Gustavsson
An on_load function is supposed to return 'true' to indicate that the module should be loaded, and 'false' if it should be unloaded. But returning any other term, as well as causing an exception, will also unload the module. Since we don't like boolean values mixed with other values, change the expected return value as follows: * If 'ok' is returned, the module will remain loaded and become callable. * If any other value is returned (or an exception is generated), the module will be unloaded. Also, if the returned value is not an atom, send a warning message to the error_logger (using error_logger:warning_msg/2). The new interpretation of the return value means that an on_load function can now directly return the return value from erlang:load_nif/2.
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.
2009-12-03documentation: Fix bugs introduced in the SGML to XML transitionHans Bolinder
In the transition from SGML to XML (several releases ago), bugs were introduced in the documentation, for instance "\n" replaced by newlines. Correct those bugs. Also correct double backslashes. They seem to have been introduced very early in the development of OTP. According to Lars they "solved" a bug in the generation of HTML &c. Now that standard tools are used instead of docbuilder, the bug has become visible.
