It's because runWorkerTask internally passes its arguments

The workaround is to pass a pointer instead:

How Appender calculate cash size?
If I right understand Appender and ~ have buffers to minimize allocations. "Appender's local capacity storage will give you a pretty big boost" (с) Adam "Appender maintains its own array metadata locally, so it can avoid global locking for each append where capacity is non-zero." (с) Docs So if I right understand appender reserve more to prevent unneeded allocations. It's seems that here is calculation new size https://github.com/dlang/phobos/blob/master/std/array.d#L3163 So it's allocate more memory that needed, but I can't understand it's algorithm. Who could explain how it's work on low level? How it's make decision how much memory needed to be pre-allocated to minimize allocations?

On the heap, unless you are allocating it via e.g. alloca.
If

MyStruct mystruct;
is located on stack, why:
MyStruct [] mystructs;

- string mystr = "lng-" ~ language;
- foreach(i, line; arrayOfLines )
li
code.mystr #{line}
I need to get HTML code like this:
some D code
But class name become "mystr" and I am getting:
some D code

Re: How to cleanup array of structs?

How to cleanup array of structs?
I remember that there was topic about remobing data from
struct/arrays of structs. But I do not remember what is idiomatic
way to do it, and can't google it.
something like:
struct MyTrack
{
ulong id;
string recordDate;
int velocity;
int maxAllowedSpeedForRoad;
}
MyTrack mytrack;
MyTrack [] mytracks;
// filling
mytracks.clean() or what?
Re: Best way for handle missing args in REST interface in vibed
I had post question here http://forum.rejectedsoftware.com/groups/rejectedsoftware.vibed/thread/43511/
Re: Best way for handle missing args in REST interface in vibed
@rootPathFromName
interface API
{
@path("mytrack") @method(HTTPMethod.GET)Json
doTrackSpeedAnalyze(int trackid, string startDateTime, string
endDateTime);
}
class MyRouter : API
{

this(Config config, Database database)
{
this.config = config;
this.database = database;
}
@path("/")
void foo(string _error = null) // I expect that this will
be called if exception happen in doTrackSpeedAnalyze
{
writeln("Error in console"); // does not writing on
console
}
override:
@errorDisplay!foo
Json doTrackSpeedAnalyze(int trackid, string
startDateTime, string endDateTime) //
/api/mytrack?trackid=123=2000=2010
{
if(endDateTime == "0")
{
throw new Exception("Some fields are empty");
}
return Json.emptyObject;
}
}
What I am doing wrong? Should I do override for foo? Should foo
present in `interface`?
Re: Best way for handle missing args in REST interface in vibed
I wrote next code:
void foo(string _error = null)
{
writeln("Error");
}
override:
@errorDisplay!foo
Json doTrackSpeedAnalyze(int trackid, string
startDateTime, string endDateTime) //
/api/mytrack?trackid=123=2000=2010
{
if(endDateTime.length == 0)
{
throw new Exception("End Date must not be empty");
}
return Json.emptyObject;
}
If I access to url: /api/mytrack?trackid=123=2000
(witout endDateTime) I am expecting execution foo() block, but it
does not happens. Why?
And what do Exception here? Why should handle it?

Getopt default int init and zero
I would like to check if user specified `0` as getopt parameter.
But the problem that `int`'s are default in `0`. So if user did
not specified nothing `int x` will be zero, and all other code
will work as if it's zero.
In std.typecons I found Nullable that allow init int to zero. I
tried to do:
Nullable!int dateInterval;
try
{
auto helpInformation = getopt(args,
"interval|i", "Interval of selection in dayes",
);
}
But I am getting error:

How to write parser?
I am trying to learn how to write text parser. I have example doc
with follow format:
#Header
my header text
##SubHeader
my sub header text
###Sub3Header
my sub 3 text
#Header21
my header2 text
##SubHeader21
my header2 text
###SubHeader22
my header3 text
I would like to wrap all level(#) tags to HTML div's, to get it's
look like:
#Header
my header text
##SubHeader
my sub header text
###Sub3Header
my sub 3 text
#Header21
my header2 text
##SubHeader21
my header2 text
###SubHeader22
my header3 text
It's seems that I wrong understand parser logic. I am trying to
do it's in next way:
bool isH1Open;
bool isH2Open;
bool isH3Open;
string newcontent;
foreach(line; content.lineSplitter)
{
if(line.length > 3) // to prevent access to line < 3 symblos
{
if(!isH1Open && line[0] == '#' && line[1] != '#')
{
isH1Open = true;
line = `` ~ "\n" ~ line ;
newcontent ~= line;
continue;
}
if(isH2Open && line[1] == '#' && line[2] != '#')
{
isH2Open = false;
line = "\n" ~ `` ~ "\n";
newcontent ~= line;
continue;
}
if(isH1Open && line[0] == '#' && line[1] != '#')

So using write[ln]() to check floating-point values isn't a
good idea as you may lose precision; hex formatting (or a
proper debugger) is a much better choice. Additionally, your
value isn't *exactly* representable; you may want to read up on
floating-point representations if that's unclear.

toISOExtString is a normal member function on DateTime, not a
static member function. If point[1].coerce!string is giving you
a string in Boost's "simple time" format (e.g. "2016-Jan-04
12:19:17"), then
DateTime.fromSimpleString(point[1].coerce!string) will give you
a DateTime. Then if you called toISOExtString() on that, e.g.
DateTime dt = DateTime.fromSimpleString(point[1].coerce!string);
string str = dt.toISOExtString();
then the string would be in the ISO extended format (e.g.
"2016-01-04T12:19:17"). If you then wanted that in the format
"2016-01-04 12:19:17", then you could just replace the 'T' with
' ', e.g.
DateTime dt = DateTime.fromSimpleString(point[1].coerce!string);
string str = dt.toISOExtString().replace("T", " ");
And if you have "2016-01-04 12:19:17", and you want to convert
that to the Boost simple time format, you could do
DateTime dt = DateTime.fromISOExtString(str.replace(" ", "T"))
auto simpleStr = dt.toSimpleString();
Hopefully, that helps.

Btw, `cargpspoints.length * typeof(cargpspoints[0]).sizeof` and `cargpspoints.length * cargpspoints[0].sizeof` show same result.

}
I expected that on every step:
`foreach(item; getTablesGPSSensorList)` structures `carGPSPoint`
will be recreated and memory will be free. But App after starting
begin eat memory, and do it till reach 1750 of RAM. After it it's
not crush, but simply stop other processing.
1. By the code on every iterate `carGPSPoint` should be recreated
and memory should be free, why this does not happen?

Can't build simple project. Very strange errors
I am getting very strange bug on very simple project. Here is sources http://rgho.st/7j5LQLZxb (blue button for downloading). On: dub build I am getting error: Unexpected OPTLINK Termination at EIP=0040F60A EAX=0393 EBX=00438C70 ECX=0EE6 EDX=02CE ESI=0104 EDI=03930468 EBP=0019FF38 ESP=0019FEF0 First=00402000 on: dub build --compiler=ldc2 It's buildable, but I am getting error on execution. The error says that file is corrupted. If comment mysql driver. database.d: import std.stdio; import std.string; import core.thread; import ddb.postgres; // import mysql; // <-- here import vibe.d; import config; the project begin buildable with dmd and ldc2 and run ok. I haven't seen such error before. I tried to clean link OPTLINK (R) for Win32 Release 8.00.17 DMD32 D Compiler v2.074.0 But I tested it on 2.073.0 too Also I tried to cleanup folder: AppData\Roaming\dub but it did not help :( Any ideas?

Well in modern operating systems that is a file with a very complex structure inside, like PE-COFF or ELF. It has a bunch of things as part of this, a dynamic relocation table, sections and symbols. Now, there is a very important symbol it provides a "main" function. Normally the libc takes ownership of this and then on calls to the c-main that we all know and love (druntime uses this and then passes it to another symbol called _Dmain). What is the difference between a shared library and an executable? Well not much, no main function for starters (although Win32 based ones do have something like it in its place) and a couple of attributes stored in the file. Executables like shared libraries are final binaries, they cannot be further linked with, at least with the most common formats + linkers anyway. You asked about the difference between a static library and a shared library, it isn't quite the right comparison. You should be asking about static libraries versus object files. In essence a static library is just a group of object files. Not too complicated. Ok, but what about Go? I have heard that it's compile all code to single exe? What is the way it's done there?

Could anybody give very easy explanation about what different between static and dynamic libs. I read a lot of information that dynamic lib allow to loading at runtime and bla-bla-bla, but still do not understand what different between compilation at dynamic and static lib. For example: 1. Does every lib can be compiler as static and as dynamic? 2. Can already compiled lib be converted to from static to dynamic and vise-versa. 3. If I have any dynamic lib, the only way is distribute it with app (or use import) or there is way to embed code from it to app? Personaly I like if I can get single bin without any external dependence. In a lot of cases size do not important, it's better to have single bin, than heap of libs.
