Re: How do I use Socket.select?

What else is there to select that I'm missing? Or is it mostly

The read set is used to determine if a socket has data waiting to 
read. It just happens that with a listening socket, that means 
there's a new connection. With a normal socket, it means data 
packets are ready. Maybe you should take a look at the classic 
Beej's guide, which covers the C API. Should be easy to translate 
to the std.socket API.

@Nemanja Boric I would not recommend calling those APIs on 
Windows because they work on entire directories, not suitable for 
individual files and sometimes  those functions not even work 
when other programs change the files in a non standard way (that 
has happened to me before when editing through a text editor)
@Enjoys Math The way I usually deal with this problem is I save 
the filename, the time and handler function in an associative 
array and loop through when something changes, this way you can 
delete, sort, etc on the map when the files are deleted or so.

Hope this helps a little.

Sure, when you get a leader that is weak on vision then he or she 
might opting for milking the customer base to satisfy stock 
owners and over time erode support… So there most certainly can 
be radical changes when the original «gründer» or a strong 
«visonary» is displaced. I think it would have been very 
difficult to displace Steve Jobs though.


You could probably make the same argument about IKEA. As long as 
the original vision is strong (good value affordable-DIY 
furniture) then it will be difficult to displace, with weak 
leadership that could erode and profits would outweigh vision and 
they would erode their brand (what-we-are-all-about).


"growing and retaining market share" is a part of "all about 
making money", to me. My definition of "not all about making 
money" is when a company does things to benefit the environment 
or citizens or employees that they could have legally avoided, 
which gives them lower profits than they would have had from 
the other course of action.


It all depends. Are the stock markets fully rational? Probably 
not, many invest based on what they think other investors will 
like and not by analysing objective measures of profits.  Some 
companies are not even on the stock market (i.e. IKEA is a 
foundation). Will stock markets only reward companies that have 
good objective profits to show to or will they also reward 
companies that have low profit margins but are insanely big?


IBM were insanely big in terms of market dominance. Silicon 
Graphics and SUN were big in high-performance computing. Where 
did that go? There is a perception that being big will 
necessarily mean large profits in the future. That may be the 
case, but it could also mean that you've got a juggernaut that is 
difficult to steer…


However, I think it is very difficult for a company over time to 
retain a strong brand vision if they only care about short-term 
profits. With weak leaders that are not capable of projecting 
visions then the share owners will take control and perhaps send 
the company in the wrong direction… With good communication of 
strong visions it is harder to get a majority behind such changes.


I see Amazon as foregoing profits now for growth - and also 
wiping out the competition - in order to reap massive profits 
in the future.  At least, I haven't heard of them foregoing 
profits in order to benefit employees, citizens or the 
environment. Their stock price has a very high valuation (PE 
ration of 285.1), reflective of investors expecting massive 
profits in the future.


Right, but how rational is that analysis? I find better deals and 
better products on dedicated netshops. If Amazon controlled the 
search applications, then it would look more certain. But as long 
as there are free price-comparison applications… Who knows if 
being that generic will be an advantage.


E.g. is it conceivable that Amazon could beat IKEA? And will 
people in the future buy physical books, music or movies? What is 
the long term market place for Amazon?


(I like Amazon for convenience though.)

That is what I see as the Apple way of doing things from their 
beginning back in the late 1970s. They make premium and/or 
unique products and then mark them up more than anybody in the 
industry. Their products have always been unique with regard to 
the OS (except for a year or two when they allowed Mac clones) 
making the situation that no other manufacturer can offer an 
identical product.


Sure, but Steve Jobs understood that they should try to make 
their products available on the grass-root level also. So they 
made a line that was affordable enough for people to buy for 
school class rooms and teenagers. Those are future customers, so 
even if you don't make large profit margins it is a good 
investment. iOS is a bit generic and identity-less compared to 
say MacOS.


Current Apple management does not understand that and schools get 
good deals on Windows PCs instead…

I realize that the challenge here is context detection; perhaps

my IDE AST tool does this and even more (detection of parameters,

I'm definitely not a MSFT fan boy.

I would probably have .NET languges installed too, which I don't.

The only thing I have in my development environment that's

have anything else installed from VS.


For the simply fact, I don't write any .NET code privately. I 
have some projects I still maintain, but I can do that without VS.


All projects I have that I currently work on are written in D or

[Issue 17979] New: Improve documentation for lazy parameters

[d-bugmail--- via Digitalmars-d-bugs]

https://issues.dlang.org/show_bug.cgi?id=17979

  Issue ID: 17979
   Summary: Improve documentation for lazy parameters
   Product: D
   Version: D2
  Hardware: x86_64
OS: Linux
Status: NEW
  Severity: enhancement
  Priority: P1
 Component: dlang.org
  Assignee: nob...@puremagic.com
  Reporter: criman...@gmail.com

Lazy parameters in fact implemented using delegates and affect @nogc
possibility. I propose additions to documentation:

https://dlang.org/spec/function.html#parameters section

It needs to write that the delegate is used, and explicitly document what
exactly happens in the case of several occurrences of the used parameter -
whether the delegate is called each time, or only the first, and then the
returned value is used (affects non-pure lazy parameters).

https://dlang.org/spec/garbage.html#op_involving_gc

It will be useful to mention lazy parameters in this list too.

A DIP could be formulated to only address the problem at hand. BTW, 
here's a really fun example:


void fun(long) { assert(0); }
void fun(bool) {}

enum int a = 2;
enum int b = 1;

void main()
{
fun(a - b);
}

The overload being called depends on (a) whether a - b can be computed 
during compilation or not, and (b) the actual value of a - b. Clearly a 
big problem for modular code. This is the smoking gun motivating the DIP.

I understand what you mean, but I don't think it is a 
scientific fact that companies are all about making money. They 
are run by humans with a set of beliefs and desires which they 
operate under…


But those humans at the top, working for public companies, are 
monitored by a board and stockholders who place "making money" as 
the main, and normally only, measure of their job performance.


Anyway, even companies that are all about making money need to 
think long term, meaning to take care of their long term 
reputation. Microsoft was not all about making money in the 
90s, but they were all about growing and retaining market share 
using bad business practices and that cost them their 
reputation among IT professionals.


"growing and retaining market share" is a part of "all about 
making money", to me. My definition of "not all about making 
money" is when a company does things to benefit the environment 
or citizens or employees that they could have legally avoided, 
which gives them lower profits than they would have had from the 
other course of action. There are donations for various causes 
made by some public companies, but I think those are normally an 
insignificant percentage of their profits.


Companies like Amazon are more about growth than making money… 
Some banks are more about being big than making money long 
term… Too big to fail and the government will save your ass. 
Etc.


I see Amazon as foregoing profits now for growth - and also 
wiping out the competition - in order to reap massive profits in 
the future.  At least, I haven't heard of them foregoing profits 
in order to benefit employees, citizens or the environment. Their 
stock price has a very high valuation (PE ration of 285.1), 
reflective of investors expecting massive profits in the future.




I don't know. I use a mac daily, but there is not a single 
product in their line today that is anywhere near good value 
compared by what you get by building your own Linux/Windows box 
or buy a quality non-Apple product from Samsung or Asus…


That is what I see as the Apple way of doing things from their 
beginning back in the late 1970s. They make premium and/or unique 
products and then mark them up more than anybody in the industry. 
Their products have always been unique with regard to the OS 
(except for a year or two when they allowed Mac clones) making 
the situation that no other manufacturer can offer an identical 
product.

The assembly code uses static allocation of registers, but 
because of the differences in how registers are used in Win64

e.g. below.

With above in place, the code can use the mnemonics to refer to 
the registers rather than the registers themselves. This allows 
the assembly code to be coded once for both architectures.

As far as I understand, the D Language Foundation itself can work

projects by the help of scholarship recipients paid by donations.

For me I see 3 ways to get enhancement / issues solved:
- Work on my spare time on the issue
- Motivate others to work in their spare time on the issue :)
- Donate to the D Language Foundation

Dub / Dub repository are already great products but in my opinion

Not sure I understand the question. Once the defines are there I 
can write following:


  | // Call luaF_close
  | mov CARG1, L   // arg1 = L
  | mov CARG2, BASE// arg2 = base
  | call extern luaF_close // call luaF_close

As you can see above, CARG1, L, CARG2, BASE are all mnemonics 
that map to registers. However this is only defined in one place.

fwiw, you can get rid of the naughty pthread_join call which would result in
undefined behaviour for detached threads by replacing it with a simple
sleep(3), which will result in the same segfault inside the D runtime,
effectively proving that a completely valid C program can call into completely

You can use just string parameters instead of enums, then you can 
pass arbitrary arguments to the instructions. The compiler will 
tell you if something is wrong with the syntax of the generated 
assembly.

How do I use Socket.select?

[Anonymouse via Digitalmars-d-learn]

I've been using blocking Sockets with timeouts for a while now, 
but wherever I look the word is "do consider using a non-blocking 
socket". Even the docs for std.socket.setOption;


In a typical application, you might also want to consider using 
a non-blocking socket instead of setting a timeout on a 
blocking one.


So I'm trying to wrap my head around select but I can't get it to 
work in any way that's better than my current blocking reads.


A SocketSet is a bundle of Sockets that you can add to and remove 
from, but you can't index. They're just there but out of reach.


A call to Socket.select(SocketSet readers, SocketSet writers, 
SocketSet error) *blocks* (unless supplied a timeout), and when 
something happens returns a number telling you how many sockets 
changed status, but not which.


The Sockets of those three SocketSets now magically disassociated 
themselves if they weren't one of those that changed status. You 
then have to call {readers,writers,error}.isSet(mySocket) and 
manually delve which one is still in there, and by extension, 
which one did change.


But a "status change" for a reading Socket is "stuff can now 
connect", for a writing one "connection established", and not 
sure about the error ones. It doesn't seem to be "there's data 
waiting to be read" which I'd hoped for, since my program (IRC 
bot) in essence connects once and stays such throughout its life.


What else is there to select that I'm missing? Or is it mostly a 
thing for programs with lots of Sockets, lots of connections?

No, the classes and structs of the examples are simply declared 
as 'static' because they are located in a 'unittest' block. You 
can ignore the keyword...it just means that they are declared as 
if they would stand at the global scope.

Yes. In conditional expressions, you get an implicitly inserted cast to
bool. So, you have an implicit, explicit cast to bool (weird as that
sounds). If the implicit cast to integers to bool were removed (meaning
neither integer literals nor VRP allowed the conversion), then it would have
no effect on if statements or loops and whatnot. It would affect
overloading and other expressions. So, something like

bool a = 2 - 1;

or

auto foo(bool) {...}
foo(1);

wouldn't compile anymore. But something like

if(1)

would compile just fine, just like

if("str")

compiles just fine, but

auto foo(bool) {...}
foo("str");

does not.

A DIP could be formulated to only address the problem at hand. 
BTW, here's a really fun example:


void fun(long) { assert(0); }
void fun(bool) {}

enum int a = 2;
enum int b = 1;

void main()
{
fun(a - b);
}

The overload being called depends on (a) whether a - b can be 
computed during compilation or not, and (b) the actual value of 
a - b. Clearly a big problem for modular code. This is the 
smoking gun motivating the DIP.


As I understand it, the case above can be solved by changing the 
overload resolution rules without deprecating the implicit 
conversion to bool.  A PR for such a fix was submitted here 
https://github.com/dlang/dmd/pull/1942.


I fear a proposal to deprecate the implicit conversion to bool 
based solely on the example above could be refused in favor of 
overload resolution changes.  IMO, the example above, while 
certainly a smoking gun, is actually just a symptom of the deeper 
problem, so I tried to make that case in the DIP.


The DIP has been submitted here 
https://github.com/dlang/DIPs/pull/99


Perhaps I'm not the right person to be formulating these 
arguments, but given that the issue has been in Bugzilla for 4 
years, I'm probably all you've got.  Sorry.

This is an ER only for Posix actually. Under Windows, 
1. the MS std C lib has the right primitive.
2. the allocator has custom primitives for the Mars std C lib (which does a new
alloc + copy)

Under Posix, the alligned alloc routines exist but only alloc / free.
So because of 2. i don't see why alloc + copy wouldn't not be done for Posix.
