• PHP: Can pcntl_alarm() and socket_select() peacefully exist in the same thread?

  - by DWilliams

  I have a PHP CLI script mostly written that functions as a chat server for chat clients to connect to (don't ask me why I'm doing it in PHP, thats another story haha). My script utilizes the socket_select() function to hang execution until something happens on a socket, at which point it wakes up, processes the event, and waits until the next event. Now, there are some routine tasks that I need performed every 30 seconds or so (check of tempbanned users should be unbanned, save user databases, other assorted things). From what I can tell, PHP doesn't have very great multi-threading support at all. My first thought was to compare a timestamp every time the socket generates an event and gets the program flowing again, but this is very inconsistent since the server could very well sit idle for hours and not have any of my cleanup routines executed. I came across the PHP pcntl extensions, and it lets me use assign a time interval for SIGALRM to get sent and a function get executed every time it's sent. This seems like the ideal solution to my problem, however pcntl_alarm() and socket_select() clash with each other pretty bad. Every time SIGALRM is triggered, all sorts of crazy things happen to my socket control code. My program is fairly lengthy so I can't post it all here, but it shouldn't matter since I don't believe I'm doing anything wrong code-wise. My question is: Is there any way for a SIGALRM to be handled in the same thread as a waiting socket_select()? If so, how? If not, what are my alternatives here? Here's some output from my program. My alarm function simply outputs "Tick!" whenever it's called to make it easy to tell when stuff is happening. This is the output (including errors) after allowing it to tick 4 times (there were no actual attempts at connecting to the server despite what it says): [05-28-10 @ 20:01:05] Chat server started on 192.168.1.28 port 4050 [05-28-10 @ 20:01:05] Loaded 2 users from file PHP Notice: Undefined offset: 0 in /home/danny/projects/PHPChatServ/ChatServ.php on line 112 PHP Warning: socket_select(): unable to select [4]: Interrupted system call in /home/danny/projects/PHPChatServ/ChatServ.php on line 116 [05-28-10 @ 20:01:15] Tick!

• BlackBerry JDE supported devices?

  - by nuggon

  I'm developing BlackBerry applications with the JDE plugin for Eclipse (version 1.0.0.67), and I was wondering if there's a list somewhere of devices that these applications will run on. It's for commercial purposes, and we need to be able to tell our clients what the supported devices are. Perhaps I'm asking a stupid question, but I need to be sure. If you need more information than what I'm giving, please ask. Thanks.

• Naming conventions for private members of .NET types

  - by Joan Venge

  Normally when I have a private field inside a class or a struct, I use camelCasing, so it would be obvious that it's indeed private when you see the name of it, but in some of my colleagues' C# code, I see that they use m_ mostly or sometimes _, like there is some sort of convention. Aren't .NET naming conventions prevent you from using underscores for member names? And when you mention the MS naming conventions or what not, they tell you it's the best way, but don't explain the reasoning behind it.

• Cleaning up C# compiler warning CS3016: Arrays as attribute arguments is not CLS-compliant

  - by mark

  I have some code, which generates this warning in several places. I want to fix them, but I do not know where they are because the C# compiler does not report the line of the error (there is an open MS Connect issue for that). Is there a tool, which can tell me where is the problematic code? IL level tool is fine, known the method name and declaring type is good enough.

• COM IUnknown and do I need a pointer to it first before calling CoGetClassObject?

  - by Tony

  In COM, when you want to create an instance of some COM Server object, do you first need to get a pointer to it's IUnknown interface and only then create a class object using CoGetClassObject? As far as I understand it, IUnknown is used to manage object lifetimes, so from my understanding, whatever object the client wants to create, one needs a pointer to it's IUnknown interface implementation first. Sound correct? If not, can anyone tell me how it works?

• Can you determine hasLayout in IE8's developer toolbar?

  - by D_N

  There was a lot of talk that IE8 was supposed to fix/remove hasLayout. Doesn't seem to have happened, though it's not usually an issue. The problem is that when it does crop up there doesn't seem to be a way for IE8's developer toolbar to tell you hasLayout is being applied, as it used to do in IE7's developer toolbar. Does anyone have a workaround? Am I missing something obvious?

  I have read about NSPasteBoard in the Apple documentation, and how it allows for applications to write into the PasteBoard and allow other applications to read that text and use it. Could someone tell me how to paste text from am application (that sits in the status bar) into a NSTextField that is inside a different application. What I am trying to do is something similar what Snippet and SnippetsApp do. If I am completely stupid and missed the obvious in Apple Docs, could you please point me to the right path :) Thanks!
