[Issue 14470] New: Reuse of object memory: new emplace overload
https://issues.dlang.org/show_bug.cgi?id=14470
Issue ID: 14470
Summary: Reuse of object memory: new emplace overload
Product: D
Version: unspecified

Severity: enhancement

As mentioned here:
http://forum.dlang.org/thread/wucqfklowovtyhpaf...@forum.dlang.org#post-ydiprvqyjrqgeahqdbwl:40forum.dlang.org
it would be nice if I could reuse object memory easily. Therefore std.conv
should add an emplace overload which takes an object:
T emplace(T, Args...)(ref T obj, auto ref Args args) if (is(T ==
class)) {
if (obj is null)
return null;
enum size_t ClassSize = __traits(classInstanceSize, T);
void[] buf = (cast(void*) obj)[0 .. ClassSize];
import std.conv : emplace;
return emplace!(T)(buf, args);
}
It would be also nice, if D could add placement-new like C++:
Foo f = new Foo(42);
new (f) Foo(23);
It looks way more cleaner and since D is aiming to be a system language,
reusing memory is a naturally behaviour.

[Issue 14471] New: std.socket: add method for detach socket handle
https://issues.dlang.org/show_bug.cgi?id=14471
Issue ID: 14471
Summary: std.socket: add method for detach socket handle
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: Phobos
Assignee: nob...@puremagic.com
Reporter: kozz...@gmail.com
Current Socket implementation has method handle which return underlying socket
and this can be use to recreate Socket with this(socket_t sock, AddressFamily
af) constructor.
This is quiet usefull when you need accept connection in one thread and
process(send data) in another.
However there is a problem with GC, which close the underlying socket.
while(true) {
if(Socket.select(...) {
auto oClientSocket = oSocket.accept();
...
auto tid = spawn(&processData, oClientSocket.handle());
send(tid, ...);
}
}
...
}
void processData(socket_t handle) {
auto oSocket = new Socket(handle, AddressFamily.INET);
/// processing some data
oSocket.send(aMsg); // this sometimes does not work, becase socket is close
from main thread
}
One workaround is put oClientSocket to some array, or disable GC. But this will
lead to bigger memory consumption. Another way is extend Socket class and
override close method to do nothing (this is what I use now).
But it would be fine if there will be some detach method on std.socket.Socket,
which will return underlying socket (same as handle method) and unset socket
hande in Socket object, so collection will not close original socket handle.

[Issue 14467] arr.capacity sometimes erroneously returns 0
https://issues.dlang.org/show_bug.cgi?id=14467 --- Comment #5 from Steven Schveighoffer --- Thank you, that is indeed the root cause. I have to investigate why that change was made, as most of the lifetime.d assumes GC.query will get the correct block info. Doing a double-lookup does not sound appealing to me as a fix, we need a function that finds the block info even for interior pointers. At this point, the array runtime is going to be severely broken performance-wise. --

Maybe the speculative devirtualization in gcc-4.9 is in some part responsible
for that. Just thinking out loud...

[Issue 14474] New: Use UTF-8 encoding for @cmdfile
https://issues.dlang.org/show_bug.cgi?id=14474 Issue ID: 14474 Summary: Use UTF-8 encoding for @cmdfile Product: D Version: D2 Hardware: x86 OS: Windows Status: NEW Severity: normal Priority: P1 Component: DMD Assignee: nob...@puremagic.com Reporter: davis...@gmail.com Currently `dmd @cmdfile` will read file as simple char string. But when DUB is compiling and creating this file it always saves it in UTF-8. This makes a problem when cmdfile contains paths (source files) with non-ASCII paths/names and thus DMD interprets them incorrectly (it always uses WinAPI ANSI functions which expects them to be encoded in Windows default ANSI code page) Such cmdfile file with non-ASCII paths encoded as UTF-8 will produce "Error: cannot read file" One solution could be to change DUB to save it in Windows default ANSI code page, but I think that's a very bad idea because then that file won't be portable. So best would be to enforce it being in UTF-8 encoding and then decode in DMD for respective code page which is used for WinAPI calls. --

[Issue 14476] New: core.thread unit tests failing on FreeBSD 9+
https://issues.dlang.org/show_bug.cgi?id=14476
Issue ID: 14476
Summary: core.thread unit tests failing on FreeBSD 9+
Product: D
Version: unspecified
Hardware: All
OS: FreeBSD
Status: NEW
Severity: major
Priority: P1
Component: druntime
Assignee: nob...@puremagic.com
Reporter: issues.dl...@jmdavisprog.com
I am consistently seeing this when I try and run druntime's unit tests on
FreeBSD for either 2.067 or master (2.068 alpha):
0.000s PASS release64 object
0.000s PASS release64 core.atomic
0.008s PASS release64 core.bitop
0.000s PASS release64 core.checkedint
0.000s PASS release64 core.demangle
0.000s PASS release64 core.exception
0.000s PASS release64 core.math
0.000s PASS release64 core.memory
posix.mak:230: recipe for target 'obj/64/core/thread' failed
gmake: *** [obj/64/core/thread] Illegal instruction
gmake: *** Deleting file 'obj/64/core/thread'
The druntime unit tests for 2.066 run just fine, so whatever the problem is was
either introduced in 2.067, or a new test that triggers it was introduced.
I'm running the latest PC-BSD on x86_64 (so FreeBSD 10.1), and someone else in
the newsgroup sees the same thing on their 9.1 i386 machine:
http://forum.dlang.org/post/koxlbjptuyccdygvk...@forum.dlang.org
The autotester is not hitting this problem, so clearly, it doesn't exist on all
FreeBSD systems However, apparently, the autotester is currently running
FreeBSD 8.4, so that would imply that the problem only exists in FreeBSD 9+. I
narrowed it down to the last test in core.thread:
unittest
{
auto thr = new Thread(function{}, 10).start();
thr.join();
}
And if I remove the ", 10" from the constructor call, then it works - but then
the druntime unit test build fails later:
Testing link
Testing load
Testing linkD
Testing linkDR
Testing loadDR
Testing host
Testing finalize
Testing link_linkdep
Makefile:28: recipe for target 'obj/freebsd/64/link_linkdep.done' failed
gmake[1]: *** [obj/freebsd/64/link_linkdep.done] Segmentation fault
gmake[1]: Leaving directory
'/usr/home/jmdavis/Programming/github/druntime/test/shared'
posix.mak:242: recipe for target 'test/shared/.run' failed
gmake: *** [test/shared/.run] Error 2
I have no idea if it's a related problem or not, but if it isn't, then another
problem was introduced in 2.067 which only exists on FreeBSD 9+. But
regardless, something about setting the stack size for threads isn't working
properly on FreeBSD 9+.
