2009-12-14Merge branch 'bg/on_load' into ccase/r13b04_devErlang/OTP
* bg/on_load: Test on_load functions that don't return 'ok' Change the expected return value for on_load functions OTP-8339 The expected return value for an on_load function has been changed. (See the section about code loading in the Reference manual.)
2009-12-14Merge branch 'bg/compiler-bopt-bug' into ccase/r13b04_devErlang/OTP
* bg/compiler-bopt-bug: beam_bool: Fix generation of code that does not validate Fix crash in beam_bool OTP-8338 Using complex boolean expressions in ifs could cause the compiler to either crash or teminate with an internal error. (Thanks to Simon Cornish.)
2009-12-14Merge branch 'as/c_nc-fix' into ccase/r13b04_devErlang/OTP
* as/c_nc-fix: c_SUITE: Use new style guard tests Fix c:nc to use outdir or cwd to find compiled object file OTP-8337 c:nc/{1,2} used to assume that the beam file was created in the same directory as the source code and failed to load the code if it was not. Corrected to look for the beam file in the current directory or in the directory specified by the {outdir,Dir} option. (Thanks to Alex Suraci.)

2009-12-14Fix c:nc to use outdir or cwd to find compiled object fileAlex Suraci
Before this patch, c:nc would naively assume the object file was created in the same location as the .erl file. This is often false, for example when an outdir is specified (often the case in make:all([netload])) or calling with c:nc("foo/bar") (because compile:file places bar.beam in the cwd, not foo/).

2009-12-13Test on_load functions that don't return 'ok'Björn Gustavsson
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.
2009-12-11beam_bool: Fix generation of code that does not validateBjörn Gustavsson
The following code (by Simon Cornish) bad(XDo1, XDo2, Do3) -> Do1 = (XDo1 =/= []), Do2 = (XDo2 =/= []), CH1 = if Do1 == true; Do1 == false,Do2==false,Do3 == blah -> ch1; true -> no end, CH2 = if Do1 == true; Do1 == false,Do2==false,Do3 == xx -> ch2; true -> no end, {CH1,CH2}. is optimized by beam_bool even though the optimization is not safe. The trouble is that an assignment to {y,0} no longer occurs on all paths leading to its use. The bug is in dst_regs/2 which is supposed to return a set of all registers assigned in a code block, but it ignores registers assigned in 'move' instructions. Fix the bug by taking 'move' instructions into account. This change is safe since it can only cause more registers to be added to the MustBeKilled and MustBeUnused sets in ensure_opt_safe/6, which means that it can only cause the optimization to be turned off for code that used to be optimized.

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 'po/blowfish_ecb_cbc_ofb-rebased' into ccase/r13b04_devErlang/OTP
* po/blowfish_ecb_cbc_ofb-rebased: Add Blowfish tests Add Blowfish ECB, CBC and OFB modes OTP-8331 The crypto module now supports Blowfish in ECB, CBC and OFB modes. (Thanks to Paul Oliver.)

2009-12-11Add Blowfish ECB, CBC and OFB modesPaul Oliver
My previous patch added CFB mode. This patch adds all remaining Blowfish modes. According to the man page http://www.fifi.org/cgi-bin/man2html/usr/share/man/man3/blowfish.3ssl.gz these are available in all versions of OpenSSL. [ Squashed in elimination of signed/unsigned compiler warnings. /bg ]
2009-12-11Update bootstrap compilerBjörn Gustavsson
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
2009-12-10Fix crash in beam_boolBjörn Gustavsson
The following code crashes beam_bool: bad(XDo1, XDo2, Do3) -> Do1 = (XDo1 =/= []), Do2 = (XDo2 =/= []), if Do1 =:= true; Do1 =:= false, Do2 =:= false, Do3 =:= delete -> no end. (Reported by Simon Cornish; minimized by Kostis Sagonas.) For the moment fix the bug in the simplest and safest way possible (basically, instead of crashing just don't do the optimization). In a future major release (e.g. R14), the following improvements could be considered: * In beam_bool, it should be possible to move the Do1 and Do2 expressions to the pre-block and still optimize the expression in the 'if' statement. * In sys_core_fold, it should be possible to eliminate the try/catch around the guard expression in the 'if', because none of the guard tests can actually fail.

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.
2009-12-09compiler: Teach 'slim' to omit compilation infoBjörn Gustavsson
The original intention for the undocumented 'slim' option was to omit non-essential parts of *.beam files to reduce the size of the primary bootstrap. Therefore, debug information and local function information (only used by xref, not by the loader) are omitted, but information about the compilation time and compiler version are still included. Including compilation information is troublesome, however, when committing the bootstrap into a revision control system, because every beam file is guaranteed to be changed every time the bootstrap is updated. Therefore, change the 'slim' option to also omit compilation information.

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.

2009-12-09.gitignore: Don't ignore script/boot files in bootstrap/binBjörn Gustavsson
The .gitignore files ignores everything in the bootstrap/bin directory, includ checked-in *.boot and *.script files. That makes it impossible to check in updates to those files without using the -f (force option) with "git add". Fix this by adding a negated pattern for script and boot files.

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.
2009-12-01Teach sys:get_status/1,2 to call Mod:format_status/2Steve Vinoski
Restore the ability for gen_server and gen_fsm callback modules to format their own state for display under the sys:get_status/1,2 calls. This ability is extremely useful for new behavior modules based on gen_server or gen_fsm, so that they can display their status in a more meaningful way than just dumping the state record. It is also generally useful for applications wanting to display their gen_server or gen_fsm callback module state in something other than the default manner. Also document the previously undocumented the gen_server:format_status/2 and gen_fsm:format_status/2 optional callback functions that, if exported by the callback module, are invoked when sys:get_status/1,2 are called. Add unit tests to ensure that format_status/2 functions exported from a gen_fsm callback module and a gen_server callback module are called when sys:get_status/1,2 are called.
