ばかでかい更新ktkr

Version D 2.020 Oct 20, 2008

New/Changed Features

Improved performance of AAs by rebalancing trees when rehashing.

immutable now is implemented.

Bugzilla 2344: Two wrong lookups for array functions

Bugzilla 2345: Return by reference should be allowed

Posix is now a predefined identifier when compiling under Linux

Based on Sean Kelly's hard work, Phobos has been split into two libraries, druntime.lib and phobos.lib. This will enable better integration with Tango. The user source code changes are:

from to

bit bool

_d_OutOfMemory() onOutOfMemoryError()

import std.asserterror; import core.exception;

import std.hiddenfunc; import core.exception;

import std.switcherr; import core.exception;

import std.array; import core.exception;

import std.outofmemory; import core.exception;

import std.gc; import core.memory;

import std.thread; import core.thread;

SwitchError SwitchException

AssertError AssertException

HiddenFuncError HiddenFuncException

ArrayBoundsError ArrayBoundsException

std.gc.fullCollect() GC.collect()

std.gc.*() memory.gc_*()

_moduleUnitTests() import runtime; runModuleUnitTests()

printf add import std.c.stdio;

Changes to thread:

The thread handle isn't exposed to the user. This can always be obtained using the appropriate OS calls from within the thread.

There is no druntime equivalent for Thread.pause() and Thread.resume(). The closest is thread_suspendAll() and thread_resumeAll()--extern (C) calls meant for use by the GC.

Thread.wait() is renamed to Thread.join().

Sleep functionality is available as Thread.sleep(double), where the parameter represents the number of seconds to sleep (fractional values accepted, obviously).

This is a big change, and expect some problems for a release or two with this.

from	to
bit	bool
_d_OutOfMemory()	onOutOfMemoryError()
import std.asserterror;	import core.exception;
import std.hiddenfunc;	import core.exception;
import std.switcherr;	import core.exception;
import std.array;	import core.exception;
import std.outofmemory;	import core.exception;
import std.gc;	import core.memory;
import std.thread;	import core.thread;
SwitchError	SwitchException
AssertError	AssertException
HiddenFuncError	HiddenFuncException
ArrayBoundsError	ArrayBoundsException
std.gc.fullCollect()	GC.collect()
std.gc.*()	memory.gc_*()
_moduleUnitTests()	import runtime; runModuleUnitTests()
printf	add import std.c.stdio;

関数が参照を返せるようになったので

ref int foo()
{   auto p = new int;
    return *p;
}
...
foo() = 3;  // reference returns can be lvalues

こう書けるようになりました．
