[Issue 5451] Three ideas for RedBlackTree
http://d.puremagic.com/issues/show_bug.cgi?id=5451 --- Comment #3 from Jonathan M Davis 2011-02-16 23:54:25 PST --- The default constructor problem should be easily solvable once RedBlackTree becomes a class, as it appears that it soon will, since Andrei has decided to make the containers in std.container classes instead of structs. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

I think my initial patch was basically correct. Overload sets are not equal to
other Objects.
int Dsymbol::equals(Object *o)
{ Dsymbol *s;
if (this == o)
return TRUE;
s = (Dsymbol *)(o);
-if (s && ident->equals(s->ident))
+// Overload sets don't have an ident
+if (s && ident && s->ident && ident->equals(s->ident))
return TRUE;
return FALSE;
}
The interesting thing, which I hadn't realized before, is that a template alias
parameter can be an overload set.
The question this raises is, are there other places in the code where it's
assumed that every DSymbol has an ident?

Yes, that's a limitation of std.format. It only provides the character ('x',
'd', 's', etc). The same thing applies to std.complex.

[Issue 5603] New: Initialization syntax for dynamic arrays
http://d.puremagic.com/issues/show_bug.cgi?id=5603
Summary: Initialization syntax for dynamic arrays
Product: D
Version: D2
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: DMD
AssignedTo: nob...@puremagic.com
ReportedBy: bearophile_h...@eml.cc
--- Comment #0 from bearophile_h...@eml.cc 2011-02-16 16:23:03 PST ---
Fixed-sized arrays allow to specify an initialization value, or to not specify
one, or to leave the stack memory untouched, for special situations where
performance matters a lot:
// program #1
void main() {
int[5] a2 = void;
int[5] a1 = 1;
int[5][5] m2 = void;
int[5][5] m1 = 1;
}
Dynamic arrays don't allow to specify an initialization value (expecially after
the deprecation of 'typedef', that used to allow the definition of a new int
type with a different init value). DMD has no syntax to allocate an unitialized
array, and currently it is not able to avoid double initializations of dynamic
arrays, an example:
// program #2
void main() {
auto a1 = new int[5];
a1[] = 1;
}
Asm of program #2 (optimized built). __d_newarrayT performs a first
initialization to zero, __memset32 performs a second initialization:
__Dmain comdat
L0: sub ESP,01Ch
mov EAX,offset FLAT:_D11TypeInfo_Ai6__initZ
push 5
push EAX
call near ptr __d_newarrayT
mov 0Ch[ESP],EAX
mov 010h[ESP],EDX
push dword ptr 0Ch[ESP]
push 1
push EDX
call near ptr __memset32
add ESP,014h
add ESP,01Ch
xor EAX,EAX
ret
So to translate the program #1 for dynamic arrays you need something like this
(I am not sure this is fully correct. GC.disable are used because m1/m2 contain
uninitialized pointers):
// program #3
import core.memory: GC;
void main() {
uint ba1 = GC.BlkAttr.NO_SCAN | GC.BlkAttr.APPENDABLE;
int n1 = 5;
int[] a1 = (cast(int*)GC.malloc(int.sizeof * n1, ba1))[0 .. n1];
uint ba2 = GC.BlkAttr.NO_SCAN | GC.BlkAttr.APPENDABLE;
int n2 = 5;
int[] a2 = (cast(int*)GC.malloc(int.sizeof * n2, ba2))[0 .. n2];
a2[] = 1;
uint ba3a = GC.BlkAttr.APPENDABLE;
uint ba3b = GC.BlkAttr.NO_SCAN | GC.BlkAttr.APPENDABLE;
int n3 = 5;
GC.disable();
int[][] m1 = (cast(int[]*)GC.malloc((int[]).sizeof * n3, ba3a))[0 .. n3];
foreach (ref row; m1)
row = (cast(int*)GC.malloc(int.sizeof * n3, ba3b))[0 .. n3];
GC.enable();
uint ba4a = GC.BlkAttr.APPENDABLE;
uint ba4b = GC.BlkAttr.NO_SCAN | GC.BlkAttr.APPENDABLE;
int n4 = 5;
GC.disable();
int[][] m2 = (cast(int[]*)GC.malloc((int[]).sizeof * n4, ba4a))[0 .. n4];
foreach (ref row; m2) {
row = (cast(int*)GC.malloc(int.sizeof * n4, ba4b))[0 .. n4];
row[] = 1;
}
GC.enable();
}
So to avoid all that bug-prone mess I suggest to allow the fixed-sized array
syntax for dynamic arrays too:
// program #4
void main() {
auto a2 = new int[5] = void;
auto a1 = new int[5] = 1;
auto m2 = new int[][](5, 5) = void;
auto m1 = new int[][](5, 5) = 1;
}

Another reduction, uses test1.d and test2.d from the previous comment. It's
clear that IFTI is not required. The issue is instantiating a tuple with an
overload set. If you change the baz(F...) to baz(F) you get:
test0.d(7): Error: template instance baz!(__anonymous) does not match template
declaration baz(F)
which shows that the overload set really doesn't have an identifier.
Also, you can replace the (F...) with (alias F), and still get the segfault. So
it is not a problem with tuples; it's a problem with overload sets of
templates.
=
import test1, test2;
void foo(A)() {}
template baz(F...)
{
enum int baz = 1;
}
static assert(baz!bar == baz!foo);

This is as odd as it gets. In Windows command-line:

module math;

import std.conv;
import std.string;
string prompt = "Enter a number: ";

auto result = to!int(readln().strip);
writeln(result);
}
I run the test module via rdmd, and enter 45:
> rdmd math.d
D:\dev\code\d_code\bugs>Enter a number: 45
'45' is not recognized as an internal or external command,
operable program or batch file.
Now I thought I'm back to command line, but it appears I'm somehow still "in"
rdmd mode:

Finally I'm back to command line

After disassembly I found out that this code was generated(no -O switch):
//asm { mov EBX,3; } bar(4);
mov ebx, 3
push4
mov ebx, large fs:2Ch
mov esi, [ebx]
calldword ptr [esi+4F4h]
mov [ebp+var_20], ebx
//the next round ecx is used...
//asm { mov EBX,5; } bar(6);
mov ebx, 5
push6
mov ecx, large fs:2Ch
mov edx, [ecx]
calldword ptr [edx+4F4h]
mov [ebp+var_20], ebx
Why is DMD not preserving the EBX register in the first call? The worst thing
is that the compiler doesn't even know tha there's something in EBX... This
problem happened to me with when EBX had a this pointer and then DMD didn't
save it and after the function pointer call I got an exception!
I think this is a serious issue and should be looked at ASAP.

The regression was caused by a Phobos change, which has triggered a compiler
segfault in interpret.c.
In attempting to instantiate map!(to), 'to' is a symbol with no identifier.
(.ident is NULL).
The segfault can be prevented in dsymbol.c, line 70, by checking for a null
identifier. But without knowing why we're getting a null identifier, I can't
recommend this as a valid patch.
int Dsymbol::equals(Object *o)
{ Dsymbol *s;
if (this == o)
return TRUE;
s = (Dsymbol *)(o);
-if (s && ident->equals(s->ident))
+if (s && s->ident && ident->equals(s->ident))

The following code works on newer hardware, but terminates with "Illegal
instruction" on some ancient CPUs (details below):
import std.conv;
void main() {
string foo = "1.0";
parse!float(foo);
}

The following code works on 2.051 but not 2.052 beta:
import std.range, std.algorithm, std.functional;
alias SortedRange!(string[], "a < b") Set;
Set readTfList(string setFile) {
string[] raw;
return pipe!(sort, uniq, array, assumeSorted)(raw);
}

The following code crashes the compiler on Windows using the latest beta of
2.052. It works on 2.051.
import std.algorithm, std.math, std.stdio, std.conv;
// std.datetime isn't used but needs to be imported to reproduce the bug.
import std.datetime;
void invert(double[][] mat) {
foreach(i, row; mat) {
double absMax = map!(abs)(row).front;
}
}
void readExp() {
auto handle = File("foo.txt");
auto lines = handle.byLine();
auto ls = lines.front().splitter('\t');
if(!ls.empty) {
auto floats = map!(to!float)(ls).front;
}
}
void main(string[] args) {}
