List of all bug fixes and enhancements in D 2.067.
Language Changes
- Destructors for structs allocated on the heap are now invoked.
Previously, when a struct allocated on the heap was freed, the destructor was not invoked. This is no longer the case, and these destructors will now be invoked before the memory is freed by the GC.
- asm statements can now be used in pure, nothrow, @nogc, or @trusted code.
By adding the appropriate attributes to an asm statement you can tell the compiler how that asm code behaves, thus allowing asm statements to be used in pure, nothrow, @nogc, or @safe functions.
asm pure nothrow @nogc @trusted { // the compiler does not check the attributes ret; }
- package protection attribute can be optionally bound to specified package
New optional syntax was added for package protection attribute:
module aaa.bbb.ccc.ddd; // accessible from any module with aaa.bbb in qualified path package(aaa.bbb) void foo() {} // old style, means same as package(aaa.bbb.ccc) package void bar() {}
- Sealed references were added (DIP25)
In @safe functions it is now required to use return ref to return a reference to a parameter or a field of it.
@safe: ref int fun(ref int a) { return a; } // ERROR ref int gun(return ref int a) { return a; } // FINE ref T hun(T)(ref T a) { return a; } // FINE, templates use deduction
See DIP25 for more details.
- The with statement now observes temporary object lifetime
A longstanding bug of the with statement was fixed which prevented the idiomatic use of RAII values.
with (File("output.log", "w")) { writeln("Content"); } // File is automatically closed
Library Changes
- This release comes with various GC optimizations that make many applications faster.
A new GC growth policy was implemented that helps to reduce the number of collections by keeping a collection threshold at 2x the size of the used memory. After each collection the used memory and the threshold are recomputed. This allows for an exponential growth of the GC heap, e.g. during program startup, but limits the heap size relative to the actual used memory. The factor 2x is configurable by setting heapSizeFactor.
The heap traversal during the marking phase is now done using tail recursion with a separate compact state stack. This allows to mark very deep heaps (lists) much faster because the previous recursion limit of 50 is eliminated.
You can see a list of all improvements here.
- volatileLoad and volatileStore intrinsics were added.
Calls to volatileLoad and volatileStore are recognized by the compiler and guaranteed to not be removed or reordered in the same thread.
void example(uint* address, uint value) { import core.bitop; // store value volatileStore(address, value); // wait until value takes affect while (volatileLoad(address) != value) { } }
Note: These intrinsics are currently in core.bitop, but will be moved to core.volatile when volatile is no longer a keyword.
- Experimental: The garbage collector can now be configured through the command line,
the environment or by options embedded into the executable.
By default, GC options can only be passed on the command line of the program to run, e.g.
app "--DRT-gcopt=profile:1 minPoolSize:16" arguments to app
Available GC options are:
- disable:0|1 - start disabled
- profile:0|1 - enable profiling with summary when terminating program
- initReserve:N - initial memory to reserve in MB
- minPoolSize:N - initial and minimum pool size in MB
- maxPoolSize:N - maximum pool size in MB
- incPoolSize:N - pool size increment MB
- heapSizeFactor:N - targeted heap size to used memory ratio
In addition, --DRT-gcopt=help will show the list of options and their current settings.
Command line options starting with "--DRT-" are filtered out before calling main, so the program will not see them. They are still available via rt_args().
Configuration via the command line can be disabled by declaring a variable for the linker to pick up before using its default from the runtime:
extern(C) __gshared bool rt_cmdline_enabled = false;
Likewise, declare a boolean rt_envvars_enabled to enable configuration via the environment variable "DRT_GCOPT:
extern(C) __gshared bool rt_envvars_enabled = true;
Setting default configuration properties in the executable can be done by specifying an array of options named rt_options:
extern(C) __gshared string[] rt_options = [ "gcopt=initReserve:100 profile:1" ];
Evaluation order of options is rt_options, then environment variables, then command line arguments, i.e. if command line arguments are not disabled, they can override options specified through the environment or embedded in the executable.
- byKeyValue was added.
Built-in associative arrays now have a .byKeyValue method that returns a forward range iterating over key/value pairs.
void main() { auto aa = ["a": 1]; foreach (pair; aa.byKeyValue) { assert(pair.key == "a"); assert(pair.value == 1); } }
- enumerate was added.
enumerate enables iteration of ranges with an index variable:
void main() { import std.stdio : stdin, stdout; import std.range : enumerate; foreach (lineNum, line; stdin.byLine().enumerate(1)) stdout.writefln("line #%s: %s", lineNum, line); }
- handle was added.
handle enables exception handling in range compositions:
import std.algorithm : equal; import std.range : retro; import std.utf : UTFException; auto str = "hello\xFFworld"; // 0xFF is an invalid UTF-8 code unit auto handled = str.handle!(UTFException, RangePrimitive.access, (e, r) => ' '); // Replace invalid code points with spaces assert(handled.equal("hello world")); // `front` is handled, assert(handled.retro.equal("dlrow olleh")); // as well as `back`
- An experimental logging system was added.
import std.experimental.logger; void main() { log("message logging in D"); }
