It seams that I can not build phobos without compiling dmd.. or maybe I don't know how... Just go and do the changes manually in your local phobos folder, wherever you have DMD installed, since you can't build phobos or dmd. Yes, this won't get into the release for a while. So please do this manually (just copy the file changed by the pull over the existing one). It's something that doesn't need to be compiled into the phobos library, as it's a misrepresentation of the actual object when you compile with unittests, so there is no reason to recompile phobos. -Steve I'm actually a linux and a mac user... this issue happens on a windows ci machine at work. I tried to update the file and compile phobos with that change, and I don't know how to make it work... ` C:\D\dmd2\src\phobos>make -f win64.mak cd etc\c\zlib make -f win64.mak MODEL=64 zlib64.lib "CC=\"\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\cl""\"" "LIB=\"\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\lib""\"" "VCDIR=\Program Files (x86)\Microsoft Visual Studio 10.0\VC" "\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\cl" /c /O2 /nologo /I"\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE" /Zl adler32.c Error: '\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64\cl' not found ` I don't know where I can find a 64bit toolchain for vs2010... I was expecting that dmd uses a newer compiler on windows... I guess that the best approach for me is to wait the next beta release of dmd and try it then... Thanks for the support!

I tried to debug the issue and it looks like the filename is valid and there is no null value. I am thinking that the value is destroyed before it reach the `GetFileAttributesW` or during that call... but I don't see how that is possible.

weird exception on windows
Hi, I noticed that sometimes on windows this line of code crashes the test suites. https://github.com/gedaiu/fluent-asserts/blob/master/core/fluentasserts/core/results.d#L1072 This exception can be captured only with a debugger... is it a dmd bug? ``` Thread 25CC created, Entry: mswsock.7FF9011604C0 EXCEPTION_DEBUG_INFO: dwFirstChance: 1 ExceptionCode: C005 (EXCEPTION_ACCESS_VIOLATION) ExceptionFlags: ExceptionAddress: 7FF9055E302C ntdll.7FF9055E302C NumberParameters: 2 ExceptionInformation[00]: Read ExceptionInformation[01]: Inaccessible Address First chance exception on 7FF9055E302C (C005, EXCEPTION_ACCESS_VIOLATION)! ``` I think this is related with this issue: https://github.com/gedaiu/fluent-asserts/issues/63 Can anyone help me with this? I don't even know how to start fixing this issue... Thanks, Bogdan
Getting the coverage data at runtime
Hi, I am wondering if there is any way of getting the code coverage at runtime... As a I seen in the runtime, the .lst files are created inside this module dealocator: https://github.com/dlang/druntime/blob/master/src/rt/cover.d#L152 and the `Cover[] gdata;` is private, so no way of accessing it... I'm asking this because it would be cool to analyse the coverage at runtime, after each executed test, for example, to see how many lines are covered by a test or to check if the test hits an assert, which will be awesome... Or maybe to add other coverage formats for better integration with IDEs... Thanks!

I don't think any of the SysTime conversion methods are pure since all of them call C functions which pull from the time zone... even if you subclassed the timezone to be pure, SysTime wouldn't pick that up since it uses the impure interface. I guess you could use a casted wrapper to hack in pure too, but I'd say just take the keyword off. Thanks!

std.algorithm can not be used inside pure functions?
Hi,
I'm trying to write a function that saves some structs as csv
file:
```
string toCsv(const(StatStorage) storage) {
return storage.values
.map!(a => [ a.name, a.begin.toISOExtString,
a.end.toISOExtString, a.status.to!string ])
.map!(a => a.join(','))
.join('\n');
}
```
I think that it's obvious that this function has no external
state and from my understanding, it should be a pure function.
But when I declare it as `pure` I get an error `Error: pure
function 'trial.reporters.stats.toCsv' cannot call impure
function 'std.array.join!(MapResult!(__lambda3,
MapResult!(__lambda2, const(Stat)[])), char).join'`.
What am I missing here?

code review based on what I learned from D
Hi,
Recently while I was reviewing some swift code, a colleague left
me the impression that I am the one with the bad habits and these
were learned while coding in D. I still think that I proposed
some changes to avoid some bugs but I was told that I am focusing
on defensive programming and that is a bad thing.
The first issue that I raised was this one:
func renderCell(item: AnyObject, index: Int) {
-fatalError(renderCell has not been implemented)
+
}
where I proposed to make that method abstract or let's not remove
the fatalError message because this method it should be never
called.
The second issue was this:
+init(dataSource: WUPTableDataSource) {
+
+self.dataSource = dataSource
+dataSource.tableView = tableView
where I asked what happens if someone passes a dataSource that
has a tableView set. I this class, there were set some events
bind to the view and it was unclear what happened in that case
and I proposed to add an assert to check if dataSource.tableView
is not set before we set it.
For both of these issues I was told that swift is not Java and if
the situations that I described happens, you don't want to crash
the user app, because this will make the user unhappy.
Those things are for me, good habits that I do when I am
programming with D. What do you think? and if I had bad ideas
with those issues, what I can do to improve my skills?
thanks,
Bogdan

Your safest bet is to use one of the many C authentication libraries out there, since D can call C functions directly. T
