How to build dmd properly?
Hello, I have the next code (minimized with DustMite):
struct Tup(T...)
{
bool opEquals() {
foreach (i; T)
static if (__traits(compiles, mixin("new
InputRangeObject11261!(abs_class)")))
msg;
}
}
/**/
void test3()
{
Tup!(int, double) ;
}
interface InputRange11261(E)
{
}
template InputRangeObject11261(R)
{
alias typeof(init.front()) E;
class InputRangeObject11261 : InputRange11261!E
{
}
}
class abs_class
{
}
The problem that I'm compiling dmd v2.083.1 and the version which
built I gives me the next error:

Re: Anonymous mapped regions increases unlimitely on spawn
So it looks like a bug, and I have reported about it: https://issues.dlang.org/show_bug.cgi?id=19487
Re: Anonymous mapped regions increases unlimitely on spawn
So more digging.. dtor of Thread calls in GC.collect() if thread is finished. But it's do nothing because bool not_registered = !next && !prev && (sm_tbeg !is this); is always true... So how to register the thread?
Re: Anonymous mapped regions increases unlimitely on spawn
So in digging by this problem, I have made simple patch to
druntime. I have added in druntime/src/core/thread.d to
final Thread start() nothrow

printf("start Thread\n");
And to
~this() nothrow @nogc
import core.stdc.stdio;
printf("detach Thread\n");
I recompiled phobos to apply changes to druntime and I see that
"start Thread" there is, but "detach Thread" printed only at the
end of process even if I do GC.collect().
So dtor of class Thread doesn't call on GC. Why?
Anonymous mapped regions increases unlimitely on spawn
Hello! I have the program which uses BDB and while testing often makes spawn. And after 12 hours of testing bdb said: mmap: Cannot allocate memory But the problem that I've found that it is not BDB created too many maps. Watching for /proc/[PID]/maps shows that number of anonymous mapped regions increases on 2 every spawn process, and never decreases even after finishing the spawned thread. According to logs my program made 32543 spawns for test time. And my /proc/sys/vm/max_map_count = 65530. So only 444 maps was allocated by other reasons and 65086 by spawn. So what to do? How to make spawn decrease count of anonymous mapped regions?

Re: How to debug FinalizeError?
No I'm not preallocating any exceptions. It was idea, but I removed all calls which can make throw. I'm using very old dmd 2.074.1, so as I have patched it for my text editor with IDE functions. I had a year break in development, so now I need to rewrite all my patches. But exactly the output of my program looks like this: core.exception.FinalizeError@src/rt/lifetime.d(1407): Finalization error === Bypassed === BerkeleyDB exceptions mixed with output of destructors || core.exception.InvalidMemoryOperationError@src/core/exception.d(696): Invalid memory operation It means that "Invalid memory operation" occurred earlier than "Finalization error"? The line on which shows the pointer src/rt/lifetime.d(1407) is exactly: onFinalizeError(*pc, e); Why gdb doesn't see this function? My program (the text editor) had run test all night under gdb with break on InvalidMemoryOperationError and didn't fall. So it is very-very-very hard to reproduce. And I haven't ideas where maybe this throw. At least I don't see any throw in explicit form.
Re: derelict-sdl2 automatically stripping the SDL_ prefix from names
Hello, as I know allMembers returns members not recursively. If
you want to get really all members you need to make recursive
function. In my program I used the next routine to print all
members of module:
static void allMembersOfModule(string module_name, bool
root=false)()
{
static if (module_name != "object" &&
module_name != __MODULE__)
{
mixin("import "~module_name~";");
pragma(msg, module_name~":");
foreach(member; __traits(allMembers, mixin(module_name)))
{
static if (__traits(compiles, mixin(member)) &&
(!__traits(compiles, __traits(getProtection,
mixin(member))) ||
__traits(getProtection, mixin(member)) !=
"private" &&
__traits(getProtection, mixin(member)) !=
"package"))
pragma(msg, member);
}
static if (root || module_name == "std.algorithm" ||
module_name == "std.range")
{
import std.algorithm.searching: startsWith;
foreach(member; __traits(allMembers,
mixin(module_name)))
{
static if (__traits(compiles, mixin(member)) &&
__traits(compiles,
mixin(member).stringof.startsWith("module ")) &&
mixin(member).stringof.startsWith("module "))
{
allMembersOfModule!(member);
}
}
}
}
}
As I know it worked good. Maybe it helps to you also.
How to debug FinalizeError?
Hello! After long-long time of debugging, I just have decided InvalidMemoryOperationError in my program. But now my program after few hours of testing again crashes with "Finalization error". What this error means exactly? I again did something wrong in destructor? And how to debug it? I tried "break onFinalizeError" in gdb like "break onInvalidMemoryOperationError", but it says: Function "onFinalizeError" not defined. There are too few information about this error in documentation and forum, and I didn't find anything about it in wiki. Thank you.

Hello! I'm trying to do some strange thing: compile some

Other function is for example:
auto megafunction()

neither a nor b are declared in this scope.
But exp.declaration._scope is null.

It is impossible to consider all it by myself. It means write the

How to make autocompletion for IDE?
Hello!
I have written my text editor with highlighting, and now I want
to add IDE features to it.
I want to make autocompletion, but not only complete members of
class/struct, but also all functions which maybe used with type,
if the first argument of the function is this type. I.e. in
"a".fromStringz() style instead of fromStringz(a).
For it I will take editable now sources, add to it lines like
this:
foreach(d; __traits(allMembers, std.string))
{
if (is(typeof(mixin("\"abc\"."~d~"()"
pragma(msg, "\"abc\"."~d~"()" );
}
So it will print all methods which can be called for strings as
"abc".function().
And I want to compile this file with options "-c -o-".
The problem that compilation for files with avarage count of
imports may take e.g. 7 seconds..
7 seconds is too long to wait autocompletion.
But compiler really do this "task" with autocompletion requests
very fast.
And I think how to implement the next:
Add the task to some other file task.d. import it to the first
file with mixin(import("task.d")). Change syscall open() to my
function which if will see that it opens "task.d" waiting the
time when user will ask autocomplete (press Ctrl-space), and then
write the task to "task.d" and continue execution of compiler...
The problem that I see in this conception is that seems not
possible write such import which will be imported only when
compiler starts handle templates and simultaneously in the place
where will be accessed all local variables of a function.
Any ideas?

How to write in D grep not slower than GNU grep?
GNU grep is pretty fast, it's tough to beat it reading one line
at a time. That's because it can play a bit of a trick and do
the initial match ignoring line boundaries and correct line
boundaries later. There's a good discussion in this thread
("Why GNU grep is fast" by Mike Haertel):

Thank you. I understand yet another trick:
$ find . -exec file -bi {} +
is the same
$ file -bi `find .`
Too slow readln
Hello, there!
I have the next "grep" code:
https://dpaste.dzfl.pl/7b7273f96ab2
And I have the directory to run it:
$ time /home/undefer/MyFiles/Projects/TEST/D/grep "HELLO" .
./strace.log: [pid 18365] write(1, "HELLO\n", 6HELLO
real1m17.096s
user0m54.828s
sys 0m13.340s
The same result I get with ldc2..
The same with bash and grep:
$ time for i in `find .`; do file -b "$i" | grep -q text && grep
-a "HELLO" "$i"; done
[pid 18365] write(1, "HELLO\n", 6HELLO
real0m42.461s
user0m23.244s
sys 0m22.300s
Only `file` for all files:
$ time find . -exec file {} + >/dev/null
real0m15.013s
user0m14.556s
sys 0m0.436s
Only grep for all files:
$ for i in `find .`; do file -b "$i" | grep -q text && echo "$i";
done > LIST1
$ time for i in `cat LIST1`; do grep -a "HELLO" "$i"; done
[pid 18365] write(1, "HELLO\n", 6HELLO
real0m4.431s
user0m1.112s
sys 0m3.148s
So 15+4.4 much lesser than 42.46. Why? How "find" so fast can run
"file" so many times?
And why 42.461s much lesser 1m17.096s?
The second version of grep:
https://dpaste.dzfl.pl/9db5bc2f0a26
$ time /home/undefer/MyFiles/Projects/TEST/D/grep2 "HELLO" `cat
LIST1`
./strace.log: [pid 18365] write(1, "HELLO\n", 6HELLO
real0m1.871s
user0m1.824s
sys 0m0.048s
$ time grep -a "HELLO" `cat LIST1`
./strace.log:[pid 18365] write(1, "HELLO\n", 6HELLO
real0m0.075s
user0m0.044s
sys 0m0.028s
The profiler says that readln eats CPU. So why 0m0.075s much
lesser 0m1.871s?

I have found, it was code like:
string path = "C:";
string parent = path[0..path.lastIndexOf("\\")];
And in mini program it works and shows diagnostic message.
Where my diagnostic message in more complicate program???

The program exits unexpectedly
Hello! I'm starting port my program to Windows _without_ Cygwin and found big trouble. My main thread exits unexpectedly without any diagnostic messages. The second thread still lives when it happens. The visual studio debugger say that thread exits with code 2. What it maybe?

The order of libraries makes error in dub
Hello, dub makes string like the next to compile my program
(WS_32.LIB at the beginning):
$ dmd -m32mscoff -lib
-of.dub\\build\\library-debug-windows-x86-dmd_2072-83D2723917096513EB360761C22DDD87\\db.lib -debug -g -w -version=Have_bdb2d WS_32.LIB libdb53d.lib source/berkeleydb/* -vcolumns
Error: Error reading file 'WS_32.LIB'
So it shows error.
In other order (libraries at the end):
$ dmd -m32mscoff -lib
-of.dub\\build\\library-debug-windows-x86-dmd_2072-83D2723917096513EB360761C22DDD87\\db.lib -debug -g -w -version=Have_bdb2d -Isource source/berkeleydb/* libdb53sd.lib WS2_32.LIB -vcolumns
No error.
But (again WS_32.LIB at beginning):
$ dmd -m32mscoff WS2_32.LIB libdb53sd.lib
transactions_test/writer source/berkeleydb/*
LINK : warning LNK4098: defaultlib 'LIBCMTD' conflicts with use
of other libs; use /NODEFAULTLIB:library
Again no error, only warning.

Re: How to use library compiled with Microsoft Visual Studio 2015 in D?
OK, I have found. It must be library WS2_32.LIB from Microsoft SDK. But dumpbin doesn't show __imp__htonl@4 symbol there. The magic! Thank you!

How to use library compiled with Microsoft Visual Studio 2015 in D?
Hello! I have compiled libdb (BerkeleyDB) with Microsoft Visual Studio 2015. 1) "Debug" mode. I have libdb53d.dll file. Do implib. The linker doesn't seen symbols from the library! Do "lib -l". In the list of symbols "db_create", linker searches "_db_create". Is it the problem? 2) "Debug-Static" mode. I have libdb53d.lib file. Try to compile. linker say that it has unsupported COFF format. Read about COFF2OMF, buy extended utils to get it. $ coff2omf libdb53d.lib Segmentation Fault Try like on page http://www.digitalmars.com/ctg/coff2omf.html: $ link /lib /convert file.lib LINK : warning LNK4044: unrecognized option '/convert'; ignored So nothing works.
