* bjorn/fun-improvements/OTP-9667: sys_pre_expand: Remove incorrect comment compiler: Eliminate use of deprecated erlang:hash/2 beam_asm: Fix broken NewIndex in fun entries beam_asm: Strenghten the calculation of Uniq for funs
2011-11-07beam_asm: Strenghten the calculation of Uniq for funsBjörn Gustavsson
Funs are identified by a triple, <Module,Uniq,Index>, where Module is the module name, Uniq is a 27 bit hash value of some intermediate representation of the code for the fun, and index is a small integer. When a fun is loaded, the triple for the fun will be compared to previously loaded funs. If all elements in the triple in the newly loaded fun are the same, the newly loaded fun will replace the previous fun. The idea is that if Uniq are the same, the code for the fun is also the same. The problem is that Uniq is only based on the intermediate representation of the fun itself. If the fun calls local functions in the same module, Uniq may remain the same even if the behavior of the fun has been changed. See http://erlang.org/pipermail/erlang-bugs/2007-June/000368.htlm for an example. As a long-term plan to fix this problem, the NewIndex and NewUniq fields was added to each fun in the R8 release (where NewUniq is the MD5 of the BEAM code for the module). Unfortunately, it turns out that the compiler does not assign unique value to NewIndex (if it isn't tested, it doesn't work), so we cannot use the <Module,NewUniq,NewIndex> triple as identification. It would be possible to use <Module,NewUniq,Index>, but that seems ugly. Therefore, fix the problem by making Uniq more unique by taking 27 bits from the MD5 for the BEAM code. That only requires a change to the compiler. Also update a test case for cover, which now fails because of the stronger Uniq calculation. (The comment in test case about why the Pid2 process survived is not correct.)
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.

2011-08-30Teach the emacs mode to compile yecc and leex filesTomas Abrahamsson
If visiting a .yrl or .xrl file in emacs with erlang-mode, then the `erlang-compile' function (normally bound to C-c C-k), now knows how to compile yecc and leex files, and then, if that compilation succeeds, also compiles the resulting .erl files. Also introduce a `erlang-compile-command-function-alist' to make it possible to hook in other functions for computing compilation commands/expressions, depending on file name.

File descriptors to import cover data are left opened. When we export and import cover data many times, leaked descriptors cause an error.
2011-04-15Inhibit electric newline after "->" when inside a type specMagnus Henoch
The Erlang mode for Emacs inserts a newline after every "->", which saves you one keystroke when writing a function, but that is inappropriate when writing a type spec, as you'd normally keep the spec on one line. This change inhibits the automatic insertion when the current line starts with "-spec" or "-type".

2011-03-09Declare indentation options as "safe" in erlang-mode for EmacsMagnus Henoch
Emacs has a facility for setting options on a per-file basis based on comments in the source file. By default, all options are considered "unsafe", and the user is queried before the variable is set. This patch declares the variables erlang-indent-level, erlang-indent-guard and erlang-argument-indent to be safe, if the value specified in the source file is valid. Such declarations usually look like this: %% -*- erlang-indent-level: 2 -*- and appear on the first line of the file.
