2010-02-02Add option to compress data when copying tables between Mnesia nodesIgor Ribeiro Sucupira
Optionally using data compression for copying Mnesia tables allows the system to be tuned to eliminate network bottlenecks from deployments where enough CPU is available to use zlib. With this patch, running erl -mnesia send_compressed <level> will enable compression for sending tables between nodes. The compression level can be any integer in [0, 9], with 0 (the default) meaning no compression (exactly the previous behaviour) and 9 being the highest compression level. To set any non-zero compression level at the sender, both nodes must have the updated Mnesia modules (the receiver will work according to the sender's configuration).

* at/windows_build_fixes: Updated README.win32 for compiling with VS2008 and issues with mc.exe Allow mc.sh and rc.sh to work when path to mc/rc.exe has spaces OTP-8345 Building on Windows will now work if the paths to mc.exe and rc.exe contain spaces. The README.win32 file has been updated with some information about building using Visual Studio 2008. (Thanks to Andrew Thompson.)
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.)
2009-12-17Fix duplicate ei_tracelevel symbolBjörn-Egil Dahlberg
The symbol ei_tracelevel was not declared extern which could crash the linking step on some compilers. Updated .gitignore to ignore object files in erl_interface.

2009-12-15Updated README.win32 for compiling with VS2008 and issues with mc.exeAndrew Thompson
Visual Studio 2008 puts some things in different places and doesn't include the Message Compiler (mc.exe).
2009-12-15Allow mc.sh and rc.sh to work when path to mc/rc.exe has spacesAndrew Thompson
The eval call in these scripts was failing for me because the path to them on my windows machine contained spaces. I also fixed some copy/paste-os from when (evidently) the mc.sh script was created by copying the rc.sh script and modifying it.

* 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.)
2009-12-14c_SUITE: Use new style guard testsBjörn Gustavsson
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.

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.
