• C# Basic Multi-Threading Question: Call Method on Thread A from Thread B (Thread B started from Thre

  - by Nick

  What is the best way to accomplish this: The main thread (Thread A) creates two other threads (Thread B and Thread C). Threads B and C do heavy disk I/O and eventually need to pass in resources they created to Thread A to then call a method in an external DLL file which requires the thread that created it to be called correctly so only Thread A can call it. The only other time I ever used threads was in a Windows Forms application, and the invoke methods were just what I needed. This program does not use Windows Forms, and as such there are no Control.Invoke methods to use. I have noticed in my testing that if a variable is created in Thread A, I have no trouble accessing and modifying it from Thread B/C which seems very wrong to me. With Winforms, I was sure it threw errors for trying to access things created on other threads. I know it is unsafe to change things from multiple threads, but I really hoped .NET would forbid it altogether to ensure safe coding. Does .NET do this, and I am just missing the boat, or does it only do it with WinForm apps? Since it does seemingly allow this, do I do something like an OS would do, create a flag and monitor it from Thread A to see if it changes. If it does, then call the method. Doesnt the event handler essentially do this, so could an event be used somehow called on the main thread?

• How to use an excel data-set for a multi-line ggplot in R?

  - by user1299887

  I have a data set in excel that I am trying to create a multiple line plot with on R. The data set contains 7 food groups and the calories consumed daily associated to the groups. As well, there is that set of data over 38 years (from 1970-2008) and I am attempting to use this data set to create a multiple line plot on R. I have tried for hours on end but can not seem to get R to recognize the variables within the data set.

• InputDispatcher Error

  - by StarDust

  INFO/ActivityManager(68): Process com.example (pid 390) has died. ERROR/InputDispatcher(68): channel '406ed580 com.example/com.example.afeTest (server)' ~ Consumer closed input channel or an error occurred. events=0x8 ERROR/InputDispatcher(68): channel '406ed580 com.example/com.example.afeTest (server)' ~ Channel is unrecoverably broken and will be disposed! ERROR/InputDispatcher(68): Received spurious receive callback for unknown input channel. fd=165, events=0x8 Can anyone tell what may be the reason behind this error? I've ported a native code on the Android-ndk. One thing I noticed regarding fd (that may be some reason :S) My code uses fd_sets which was defined in winsock2.h But I didn't find fd_sets defined in android-ndk. So I had included "select.h" where fd_set is a typedef in the android-ndk: typedef __kernel_fd_set fd_set; Here is the log cat: 04-06 11:15:32.405: INFO/DEBUG(31): *** *** *** *** *** *** *** *** ***

• What is the best way to configure Apache or AWS to support a Rails multi tenancy application that allows each customer to have their own domain name?

  - by Ryan Arneson

  I'm building a Rails 3 SaaS site that allows for multi-tenancy. When a customer signs up they put in their own domain name, e.g. example.com. I need example.com to point to my SaaS application and serve them their content. My questions are as follows: Do I need to create an Apache vhost for each customer using their own domain? Is there an easier way with CNAME's to just have the customer point to the IP address of my server(s) that then forwards the request onto my application through some catch all vhost? Would I be able to create the CNAME record for the customer so they don't have to do any setup? Would this be a case better suited to Amazon Web Services? Any help or explanation or corrections on my understanding of dns would be appreciated. I'm a developer so the server ops portion of this is a bit cloudy.

• Running two Magentos installations, one of which has 3 stores set up as multi-store. Which server?

  - by Pedro Peixoto

  I want to run 4 Magento stores in 2 different installations. 1 is a standalonne installation with 3 languages. The other is a multi-store with 3 different online stores in different domains. At the moment we have a VPS with 1GB memory, would that be enough? I ask because I've finished the standalone store and already put it online, and the server is already running on 62% memory. The ideal would be that this is enough as my company wouldn't like to move to a Dedicated Server (as it involves costs). I'm sure I can try to optimize Magento to run on lower memory (I'm expecting visits averaging 2000/day on all sites), if I could have some tips on the best way to do that Id appreciate it too.

So do I have to change to or pick any specific channel for installation? Please tell me is their any stable and properly working channel which I should choose for installation or what should I do?

• Use native HBitmap in C# while preserving alpha channel/transparency. Please check this code, it works on my computer...

  - by David

  Let's say I get a HBITMAP object/handle from a native Windows function. I can convert it to a managed bitmap using Bitmap.FromHbitmap(nativeHBitmap), but if the native image has transparency information (alpha channel), it is lost by this conversion. There are a few questions on Stack Overflow regarding this issue. Using information from the first answer of this question (How to draw ARGB bitmap using GDI+?), I wrote a piece of code that I've tried and it works. It basically gets the native HBitmap width, height and the pointer to the location of the pixel data using GetObject and the BITMAP structure, and then calls the managed Bitmap constructor: Bitmap managedBitmap = new Bitmap(bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); As I understand (please correct me if I'm wrong), this does not copy the actual pixel data from the native HBitmap to the managed bitmap, it simply points the managed bitmap to the pixel data from the native HBitmap. And I don't draw the bitmap here on another Graphics (DC) or on another bitmap, to avoid unnecessary memory copying, especially for large bitmaps. I can simply assign this bitmap to a PictureBox control or the the Form BackgroundImage property. And it works, the bitmap is displayed correctly, using transparency. When I no longer use the bitmap, I make sure the BackgroundImage property is no longer pointing to the bitmap, and I dispose both the managed bitmap and the native HBitmap. The Question: Can you tell me if this reasoning and code seems correct. I hope I will not get some unexpected behaviors or errors. And I hope I'm freeing all the memory and objects correctly. private void Example() { IntPtr nativeHBitmap = IntPtr.Zero; /* Get the native HBitmap object from a Windows function here */ // Create the BITMAP structure and get info from our nativeHBitmap NativeMethods.BITMAP bitmapStruct = new NativeMethods.BITMAP(); NativeMethods.GetObjectBitmap(nativeHBitmap, Marshal.SizeOf(bitmapStruct), ref bitmapStruct); // Create the managed bitmap using the pointer to the pixel data of the native HBitmap Bitmap managedBitmap = new Bitmap( bitmapStruct.bmWidth, bitmapStruct.bmHeight, bitmapStruct.bmWidth * 4, PixelFormat.Format32bppArgb, bitmapStruct.bmBits); // Show the bitmap this.BackgroundImage = managedBitmap; /* Run the program, use the image */ MessageBox.Show("running..."); // When the image is no longer needed, dispose both the managed Bitmap object and the native HBitmap this.BackgroundImage = null; managedBitmap.Dispose(); NativeMethods.DeleteObject(nativeHBitmap); } internal static class NativeMethods { [StructLayout(LayoutKind.Sequential)] public struct BITMAP { public int bmType; public int bmWidth; public int bmHeight; public int bmWidthBytes; public ushort bmPlanes; public ushort bmBitsPixel; public IntPtr bmBits; } [DllImport("gdi32", CharSet = CharSet.Auto, EntryPoint = "GetObject")] public static extern int GetObjectBitmap(IntPtr hObject, int nCount, ref BITMAP lpObject); [DllImport("gdi32.dll")] internal static extern bool DeleteObject(IntPtr hObject); }

• How to install DBD::mysql on OS X Server 10.6?

  - by Zoran Simic

  Trying to install DBD::mysql on OS X Server 10.6 (mac mini server). But I'm missing the mysql headers apparently. Since mysql is already part of OS X Server 10.6, I would like to NOT install anything else (no fink or darwin ports installs), just whatever's needed to get DBD::mysql installed and working. Do you know how I could do that? Do I have to install the headers somewhere? And if so, where? (again: I don't want to install another version of mysql on the box, want to use the version it came with). Is there a way to install DBD::mysql without compiling any C files? This is the error I get (the actual error is much longer, but these are the most meaningful bits, this is the first error reported). Checking if your kit is complete...

• How do I install Citrix receiver?

  Has anyone managed to get the Citrix receiver client working in 64-bit Natty (11.04). It seems libmotif4 won't install multi-arch (32 bit and 64 bit libraries). I also see crazy dependency errors despite the libraries being present. Here is what I received initially when trying to install icaclient.deb from Citrix; sudo dpkg -i Downloads/icaclient_11.100_i386.patched.deb dpkg: error processing Downloads/icaclient_11.100_i386.patched.deb (--install): package architecture (i386) does not match system (amd64) Errors were encountered while processing: Downloads/icaclient_11.100_i386.patched.deb I then installed the 32 bit libraries. sudo apt-get install ia32-libs ia32-libs-gtk Then I noticed libmotif4 (a dependency of the citrix client) wasn't present so I installed the 64bit version. sudo apt-get install libmotif4 I then tried to force the 32 bit version; sudo dpkg --force-architecture -i Downloads/libmotif4_2.3.3-5_i386.deb dpkg: warning: overriding problem because --force enabled: package architecture (i386) does not match system (amd64) Selecting previously deselected package libmotif4:i386. dpkg: error processing Downloads/libmotif4_2.3.3-5_i386.deb (--install): libmotif4:i386 2.3.3-5 (Multi-Arch: no) is not co-installable with libmotif4:amd64 2.3.3-5ubuntu1 (Multi-Arch: no) which is currently installed So I uninstalled the 64 bit version and tried to install the 32 bit version. This worked, but when I attempt to install Citrix I enter dependency hell. sudo dpkg --force-architecture -i Downloads/icaclient_11.100_i386.patched.deb dpkg: warning: overriding problem because --force enabled: package architecture (i386) does not match system (amd64) Selecting previously deselected package icaclient:i386.

Unpacking icaclient:i386 (from .../icaclient_11.100_i386.patched.deb) ... dpkg: dependency problems prevent configuration of icaclient:i386: icaclient:i386 depends on libc6 (>= 2.3). icaclient:i386 depends on libice6 (>= 1:1.0.0). icaclient:i386 depends on libsm6. icaclient:i386 depends on libx11-6. icaclient:i386 depends on libxaw7. icaclient:i386 depends on libxext6. icaclient:i386 depends on libxmu6. icaclient:i386 depends on libxp6. icaclient:i386 depends on libxpm4. icaclient:i386 depends on libxt6. dpkg: error processing icaclient:i386 (--install): dependency problems - leaving unconfigured Errors were encountered while processing: icaclient:i386 So the state it's in, there's no icaclient binaries installed only the docs. It is complaining about libraries that are indeed present (libc6 64 bit and 32 bit). libmotif4 is only 32 bit installed and won't install alongside libmotif4 64 bit. libmotif4 error when you try to install it alongside the 32bit instance; libmotif4:amd64 2.3.3-5 (Multi-Arch: no) is not co-installable with libmotif4:i386 2.3.3-5ubuntu1 (Multi-Arch: no) which is currently installed Any tips?

• Why is multithreading often preferred for improving performance?

  - by user1849534

  I have a question, it's about why programmers seems to love concurrency and multi-threaded programs in general. I'm considering 2 main approaches here: an async approach basically based on signals, or just an async approach as called by many papers and languages like the new C# 5.0 for example, and a "companion thread" that manages the policy of your pipeline a concurrent approach or multi-threading approach I will just say that I'm thinking about the hardware here and the worst case scenario, and I have tested this 2 paradigms myself, the async paradigm is a winner at the point that I don't get why people 90% of the time talk about multi-threading when they want to speed up things or make a good use of their resources. I have tested multi-threaded programs and async program on an old machine with an Intel quad-core that doesn't offer a memory controller inside the CPU, the memory is managed entirely by the motherboard, well in this case performances are horrible with a multi-threaded application, even a relatively low number of threads like 3-4-5 can be a problem, the application is unresponsive and is just slow and unpleasant. A good async approach is, on the other hand, probably not faster but it's not worst either, my application just waits for the result and doesn't hangs, it's responsive and there is a much better scaling going on. I have also discovered that a context change in the threading world it's not that cheap in real world scenario, it's in fact quite expensive especially when you have more than 2 threads that need to cycle and swap among each other to be computed. On modern CPUs the situation it's not really that different, the memory controller it's integrated but my point is that an x86 CPUs is basically a serial machine and the memory controller works the same way as with the old machine with an external memory controller on the motherboard. The context switch is still a relevant cost in my application and the fact that the memory controller it's integrated or that the newer CPU have more than 2 core it's not bargain for me. For what i have experienced the concurrent approach is good in theory but not that good in practice, with the memory model imposed by the hardware, it's hard to make a good use of this paradigm, also it introduces a lot of issues ranging from the use of my data structures to the join of multiple threads. Also both paradigms do not offer any security abut when the task or the job will be done in a certain point in time, making them really similar from a functional point of view. According to the X86 memory model, why the majority of people suggest to use concurrency with C++ and not just an async approach ? Also why not considering the worst case scenario of a computer where the context switch is probably more expensive than the computation itself ?

• When is a SQL function not a function?

  - by Rob Farley

  Should SQL Server even have functions? (Oh yeah – this is a T-SQL Tuesday post, hosted this month by Brad Schulz) Functions serve an important part of programming, in almost any language. A function is a piece of code that is designed to return something, as opposed to a piece of code which isn’t designed to return anything (which is known as a procedure). SQL Server is no different. You can call stored procedures, even from within other stored procedures, and you can call functions and use these in other queries. Stored procedures might query something, and therefore ‘return data’, but a function in SQL is considered to have the type of the thing returned, and can be used accordingly in queries. Consider the internal GETDATE() function. SELECT GETDATE(), SomeDatetimeColumn FROM dbo.SomeTable; There’s no logical difference between the field that is being returned by the function and the field that’s being returned by the table column. Both are the datetime field – if you didn’t have inside knowledge, you wouldn’t necessarily be able to tell which was which. And so as developers, we find ourselves wanting to create functions that return all kinds of things – functions which look up values based on codes, functions which do string manipulation, and so on. But it’s rubbish. Ok, it’s not all rubbish, but it mostly is. And this isn’t even considering the SARGability impact. It’s far more significant than that. (When I say the SARGability aspect, I mean “because you’re unlikely to have an index on the result of some function that’s applied to a column, so try to invert the function and query the column in an unchanged manner”) I’m going to consider the three main types of user-defined functions in SQL Server: Scalar Inline Table-Valued Multi-statement Table-Valued I could also look at user-defined CLR functions, including aggregate functions, but not today. I figure that most people don’t tend to get around to doing CLR functions, and I’m going to focus on the T-SQL-based user-defined functions. Most people split these types of function up into two types. So do I. Except that most people pick them based on ‘scalar or table-valued’. I’d rather go with ‘inline or not’. If it’s not inline, it’s rubbish. It really is. Let’s start by considering the two kinds of table-valued function, and compare them. These functions are going to return the sales for a particular salesperson in a particular year, from the AdventureWorks database. CREATE FUNCTION dbo.FetchSales_inline(@salespersonid int, @orderyear int) RETURNS TABLE AS  RETURN (     SELECT e.LoginID as EmployeeLogin, o.OrderDate, o.SalesOrderID     FROM Sales.SalesOrderHeader AS o     LEFT JOIN HumanResources.Employee AS e     ON e.EmployeeID = o.SalesPersonID     WHERE o.SalesPersonID = @salespersonid     AND o.OrderDate >= DATEADD(year,@orderyear-2000,'20000101')     AND o.OrderDate < DATEADD(year,@orderyear-2000+1,'20000101') ) ; GO CREATE FUNCTION dbo.FetchSales_multi(@salespersonid int, @orderyear int) RETURNS @results TABLE (     EmployeeLogin nvarchar(512),     OrderDate datetime,     SalesOrderID int     ) AS BEGIN     INSERT @results (EmployeeLogin, OrderDate, SalesOrderID)     SELECT e.LoginID, o.OrderDate, o.SalesOrderID     FROM Sales.SalesOrderHeader AS o     LEFT JOIN HumanResources.Employee AS e     ON e.EmployeeID = o.SalesPersonID     WHERE o.SalesPersonID = @salespersonid     AND o.OrderDate >= DATEADD(year,@orderyear-2000,'20000101')     AND o.OrderDate < DATEADD(year,@orderyear-2000+1,'20000101')     ;     RETURN END ; GO You’ll notice that I’m being nice and responsible with the use of the DATEADD function, so that I have SARGability on the OrderDate filter. Regular readers will be hoping I’ll show what’s going on in the execution plans here. Here I’ve run two SELECT * queries with the “Show Actual Execution Plan” option turned on. Notice that the ‘Query cost’ of the multi-statement version is just 2% of the ‘Batch cost’. But also notice there’s trickery going on. And it’s nothing to do with that extra index that I have on the OrderDate column. Trickery. Look at it – clearly, the first plan is showing us what’s going on inside the function, but the second one isn’t. The second one is blindly running the function, and then scanning the results. There’s a Sequence operator which is calling the TVF operator, and then calling a Table Scan to get the results of that function for the SELECT operator. But surely it still has to do all the work that the first one is doing... To see what’s actually going on, let’s look at the Estimated plan. Now, we see the same plans (almost) that we saw in the Actuals, but we have an extra one – the one that was used for the TVF. Here’s where we see the inner workings of it. You’ll probably recognise the right-hand side of the TVF’s plan as looking very similar to the first plan – but it’s now being called by a stack of other operators, including an INSERT statement to be able to populate the table variable that the multi-statement TVF requires. And the cost of the TVF is 57% of the batch! But it gets worse. Let’s consider what happens if we don’t need all the columns. We’ll leave out the EmployeeLogin column. Here, we see that the inline function call has been simplified down. It doesn’t need the Employee table. The join is redundant and has been eliminated from the plan, making it even cheaper. But the multi-statement plan runs the whole thing as before, only removing the extra column when the Table Scan is performed. A multi-statement function is a lot more powerful than an inline one. An inline function can only be the result of a single sub-query. It’s essentially the same as a parameterised view, because views demonstrate this same behaviour of extracting the definition of the view and using it in the outer query. A multi-statement function is clearly more powerful because it can contain far more complex logic. But a multi-statement function isn’t really a function at all. It’s a stored procedure. It’s wrapped up like a function, but behaves like a stored procedure. It would be completely unreasonable to expect that a stored procedure could be simplified down to recognise that not all the columns might be needed, but yet this is part of the pain associated with this procedural function situation. The biggest clue that a multi-statement function is more like a stored procedure than a function is the “BEGIN” and “END” statements that surround the code. If you try to create a multi-statement function without these statements, you’ll get an error – they are very much required. When I used to present on this kind of thing, I even used to call it “The Dangers of BEGIN and END”, and yes, I’ve written about this type of thing before in a similarly-named post over at my old blog. Now how about scalar functions... Suppose we wanted a scalar function to return the count of these. CREATE FUNCTION dbo.FetchSales_scalar(@salespersonid int, @orderyear int) RETURNS int AS BEGIN     RETURN (         SELECT COUNT(*)         FROM Sales.SalesOrderHeader AS o         LEFT JOIN HumanResources.Employee AS e         ON e.EmployeeID = o.SalesPersonID         WHERE o.SalesPersonID = @salespersonid         AND o.OrderDate >= DATEADD(year,@orderyear-2000,'20000101')         AND o.OrderDate < DATEADD(year,@orderyear-2000+1,'20000101')     ); END ; GO Notice the evil words? They’re required. Try to remove them, you just get an error. That’s right – any scalar function is procedural, despite the fact that you wrap up a sub-query inside that RETURN statement. It’s as ugly as anything. Hopefully this will change in future versions. Let’s have a look at how this is reflected in an execution plan. Here’s a query, its Actual plan, and its Estimated plan: SELECT e.LoginID, y.year, dbo.FetchSales_scalar(p.SalesPersonID, y.year) AS NumSales FROM (VALUES (2001),(2002),(2003),(2004)) AS y (year) CROSS JOIN Sales.SalesPerson AS p LEFT JOIN HumanResources.Employee AS e ON e.EmployeeID = p.SalesPersonID; We see here that the cost of the scalar function is about twice that of the outer query. Nicely, the query optimizer has worked out that it doesn’t need the Employee table, but that’s a bit of a red herring here. There’s actually something way more significant going on. If I look at the properties of that UDF operator, it tells me that the Estimated Subtree Cost is 0.337999. If I just run the query SELECT dbo.FetchSales_scalar(281,2003); we see that the UDF cost is still unchanged. You see, this 0.0337999 is the cost of running the scalar function ONCE. But when we ran that query with the CROSS JOIN in it, we returned quite a few rows. 68 in fact. Could’ve been a lot more, if we’d had more salespeople or more years. And so we come to the biggest problem. This procedure (I don’t want to call it a function) is getting called 68 times – each one between twice as expensive as the outer query. And because it’s calling it in a separate context, there is even more overhead that I haven’t considered here. The cheek of it, to say that the Compute Scalar operator here costs 0%! I know a number of IT projects that could’ve used that kind of costing method, but that’s another story that I’m not going to go into here. Let’s look at a better way. Suppose our scalar function had been implemented as an inline one. Then it could have been expanded out like a sub-query. It could’ve run something like this: SELECT e.LoginID, y.year, (SELECT COUNT(*)     FROM Sales.SalesOrderHeader AS o     LEFT JOIN HumanResources.Employee AS e     ON e.EmployeeID = o.SalesPersonID     WHERE o.SalesPersonID = p.SalesPersonID     AND o.OrderDate >= DATEADD(year,y.year-2000,'20000101')     AND o.OrderDate < DATEADD(year,y.year-2000+1,'20000101')     ) AS NumSales FROM (VALUES (2001),(2002),(2003),(2004)) AS y (year) CROSS JOIN Sales.SalesPerson AS p LEFT JOIN HumanResources.Employee AS e ON e.EmployeeID = p.SalesPersonID; Don’t worry too much about the Scan of the SalesOrderHeader underneath a Nested Loop. If you remember from plenty of other posts on the matter, execution plans don’t push the data through. That Scan only runs once. The Index Spool sucks the data out of it and populates a structure that is used to feed the Stream Aggregate. The Index Spool operator gets called 68 times, but the Scan only once (the Number of Executions property demonstrates this). Here, the Query Optimizer has a full picture of what’s being asked, and can make the appropriate decision about how it accesses the data. It can simplify it down properly. To get this kind of behaviour from a function, we need it to be inline. But without inline scalar functions, we need to make our function be table-valued. Luckily, that’s ok. CREATE FUNCTION dbo.FetchSales_inline2(@salespersonid int, @orderyear int) RETURNS table AS RETURN (SELECT COUNT(*) as NumSales     FROM Sales.SalesOrderHeader AS o     LEFT JOIN HumanResources.Employee AS e     ON e.EmployeeID = o.SalesPersonID     WHERE o.SalesPersonID = @salespersonid     AND o.OrderDate >= DATEADD(year,@orderyear-2000,'20000101')     AND o.OrderDate < DATEADD(year,@orderyear-2000+1,'20000101') ); GO But we can’t use this as a scalar. Instead, we need to use it with the APPLY operator. SELECT e.LoginID, y.year, n.NumSales FROM (VALUES (2001),(2002),(2003),(2004)) AS y (year) CROSS JOIN Sales.SalesPerson AS p LEFT JOIN HumanResources.Employee AS e ON e.EmployeeID = p.SalesPersonID OUTER APPLY dbo.FetchSales_inline2(p.SalesPersonID, y.year) AS n; And now, we get the plan that we want for this query. All we’ve done is tell the function that it’s returning a table instead of a single value, and removed the BEGIN and END statements. We’ve had to name the column being returned, but what we’ve gained is an actual inline simplifiable function. And if we wanted it to return multiple columns, it could do that too. I really consider this function to be superior to the scalar function in every way. It does need to be handled differently in the outer query, but in many ways it’s a more elegant method there too. The function calls can be put amongst the FROM clause, where they can then be used in the WHERE or GROUP BY clauses without fear of calling the function multiple times (another horrible side effect of functions). So please. If you see BEGIN and END in a function, remember it’s not really a function, it’s a procedure. And then fix it. @rob_farley

• Question about POP3 message termination octet

  - by user361633

  This is from the POP3 RFC. "Responses to certain commands are multi-line. In these cases, which are clearly indicated below, after sending the first line of the response and a CRLF, any additional lines are sent, each terminated by a CRLF pair. When all lines of the response have been sent, a final line is sent, consisting of a termination octet (decimal code 046, ".") and a CRLF pair. If any line of the multi-line response begins with the termination octet, the line is "byte-stuffed" by pre-pending the termination octet to that line of the response. Hence a multi-line response is terminated with the five octets "CRLF.CRLF". When examining a multi-line response, the client checks to see if the line begins with the termination octet. If so and if octets other than CRLF follow, the first octet of the line (the termination octet) is stripped away. If so and if CRLF immediately follows the termination character, then the response from the POP server is ended and the line containing ".CRLF" is not considered part of the multi-line response." Well, i have problem with this, for example gmail sometimes sends the termination octet and then in the NEXT LINE sends the CRLF pair. For example: "+OK blah blah" "blah blah." "\r\n" That's very rare, but it happens sometimes, so obviously i'm unable to determine the end of the message in such case, because i'm expecting a line that consists of '.\r\n'. Seriously, is Gmail violating the POP3 protocol or i'm doing something wrong? Also i have a second question, english is not my first language so i cannot understand that completely: "If any line of the multi-line response begins with the termination octet, the line is "byte-stuffed" by pre-pending the termination octet to that line of the response. Hence a multi-line response is terminated with the five octets "CRLF.CRLF"." When exactly CRLF.CRLF is used? Can someone gives me a simple example? The rfc says that is used when any line of the response begins with the termination octet. But i don't see any lines that starts with '.' in the messages that are terminated with CRLF.CRLF. I checked that. Maybe i don't understand something, that's why i'm asking.

• Mac OS X 10.6 Setup for Apache/MySQL/Perl

  - by Russell C.

  I just got a new Mac and have been trying to setup a local development environment for my perl applications for a few days now with no luck. I'm getting no where fast so I hope someone else who has done this successfully could help. I started by installing MAMP which I thought would take care of everything for me but unfortunately it doesn't take care of some important perl modules. I used CPAN to install all our required modules except that it seems DBD::mysql doesn't install correctly through CPAN. After reading a lot online, lots of people reported problems with this and recommended using MacPorts to install the module which I have tried doing with no luck using the following command: sudo port install p5-dbd-mysql After what seems like a successful install of DBD::mysql, Apache continues to report the following error when trying to run any of our Perl scripts: [Fri Apr 30 18:51:07 2010] [error] [client 127.0.0.1] install_driver(mysql) failed: Can't locate DBD/mysql.pm in @INC (@INC contains: /Library/Perl/Updates/5.10.0/darwin-thread-multi-2level /Library/Perl/Updates/5.10.0 /System/Library/Perl/5.10.0/darwin-thread-multi-2level /System/Library/Perl/5.10.0 /Library/Perl/5.10.0/darwin-thread-multi-2level /Library/Perl/5.10.0 /Network/Library/Perl/5.10.0/darwin-thread-multi-2level /Network/Library/Perl/5.10.0 /Network/Library/Perl /System/Library/Perl/Extras/5.10.0/darwin-thread-multi-2level /System/Library/Perl/Extras/5.10.0 .) at (eval 1835) line 3.

• Using RabbitMQ (Java client), is there a way to determine if network connection is closed during con

  - by MItch Branting

  I'm using RabbitMQ on RHEL 5.3 using the Java client. I have 2 nodes (machines). Node1 is consuming messages from a queue on Node2 using the Java helper class QueueingConsumer. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(); ... Process message - delivery.getBody() } If the interface is brought down on Node1 or Node2 (e.g. ifconfig eth1 down), the client (above) never knows the network isn't there anymore. Does RabbitMQ provide some type of configuration on the Java client that can be used to determine if the connection has gone away. Shutting down the RabbitMQ server on Node2 will trigger a ShutdownSignalException, which can be caught and the app can go into a reconnect loop. But bringing down the interface doesn't cause any type of exception to happen, so the code will be waiting forever on consumer.nextDelivery(). I've also tried using the timeout version of this call. e.g. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); int timeout_ms = 30000; while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(timeout_ms); if (delivery == null) { if (channel.isOpen() == false) // Seems to always return true { throw new ShutdownSignalException(); } } else { ... Process message - delivery.getBody() } } but appears that this always returns true (even though the interface is down). I assume registering for the ShutdownListener on the connection will yield the same results, but haven't tried that yet. Is there a way to configure some sort of heartbeat, or do you just have to write custom lease logic (e.g. "I'm here now") in order to get this to work?

• Remote EJB lookup issue with WebSphere 6.1

  - by marc dauncey

  I've seen this question asked before, but I've tried various solutions proposed, to no avail. Essentially, I have two EJB enterprise applications, that need to communicate with one another. The first is a web application, the second is a search server - they are located on different development servers, not in the same node, cell, or JVM, although they are on the same physical box. I'm doing the JNDI lookup via IIOP, and the URL I am using is as follows: iiop://searchserver:2819 In my hosts file, I've set searchserver to 127.0.0.1. The ports for my search server are bound to this hostname too. However, when the web app (that uses Spring btw) attempts to lookup the search EJB, it fails with the following error. This is driving me nuts, surely this kind of comms between the servers should be fairly simple to get working. I've checked the ports and they are correct. I note that the exception says the initial context is H00723Node03Cell/nodes/H00723Node03/servers/server1, name: ejb/com/hmv/dataaccess/ejb/hmvsearch/HMVSearchHome. This is the web apps server NOT the search server. Is this correct? How can I get Spring to use the right context?

• fmod VS2008 unresolved externals in dependant project

  - by Tom J Nowell

  Im currently trying to use the latest stable fmod ex in my project. I have a main executable in a project called engine4, and a project named DX9Platform in the solution as well which ti depends on. All the fmod code is in this DX9Platform project, which generates a lib file. DX9Platform includes fmodex_vc.lib and builds fine. However buildign Engien4 results in unresolved external symbol messages referencing files that use fmod in the DX9Platform project I have tried adding fmodex_vc.lib to the Engine4 project, with no success, how do I fix this? Heres the linker output: 3>------ Build started: Project: Engine4, Configuration: Release Direct3D9 Win32 ------ 3>Linking... 3>DX9PlatformLib.lib(CFmodSound.obj) : error LNK2001: unresolved external symbol _FMOD_System_Create 3>DX9PlatformLib.lib(CFmodSound.obj) : error LNK2001: unresolved external symbol "public: enum FMOD_RESULT __thiscall FMOD::System::createSound(char const *,unsigned int,struct FMOD_CREATESOUNDEXINFO *,class FMOD::Sound * *)" (?createSound@System@FMOD@@QAE?AW4FMOD_RESULT@@PBDIPAUFMOD_CREATESOUNDEXINFO@@PAPAVSound@2@@Z) 3>DX9PlatformLib.lib(CFmodSound.obj) : error LNK2001: unresolved external symbol "public: enum FMOD_RESULT __thiscall FMOD::System::getVersion(unsigned int *)" (?getVersion@System@FMOD@@QAE?AW4FMOD_RESULT@@PAI@Z) 3>DX9PlatformLib.lib(CFmodSound.obj) : error LNK2001: unresolved external symbol "public: enum FMOD_RESULT __thiscall FMOD::System::init(int,unsigned int,void *)" (?init@System@FMOD@@QAE?AW4FMOD_RESULT@@HIPAX@Z) 3>DX9PlatformLib.lib(CFModAudioObject.obj) : error LNK2001: unresolved external symbol "public: enum FMOD_RESULT __thiscall FMOD::System::playSound(enum FMOD_CHANNELINDEX,class FMOD::Sound *,bool,class FMOD::Channel * *)" (?playSound@System@FMOD@@QAE?AW4FMOD_RESULT@@W4FMOD_CHANNELINDEX@@PAVSound@2@_NPAPAVChannel@2@@Z) 3>DX9PlatformLib.lib(CFModAudioObject.obj) : error LNK2001: unresolved external symbol "public: enum FMOD_RESULT __thiscall FMOD::Channel::getPaused(bool *)" (?getPaused@Channel@FMOD@@QAE?AW4FMOD_RESULT@@PA_N@Z) 3>DX9PlatformLib.lib(CFModAudioObject.obj) : error LNK2001: unresolved external symbol "public: enum FMOD_RESULT __thiscall FMOD::Channel::setPaused(bool)" (?setPaused@Channel@FMOD@@QAE?AW4FMOD_RESULT@@_N@Z) 3>DX9PlatformLib.lib(CFModAudioObject.obj) : error LNK2001: unresolved external symbol "public: virtual class IAudioObject * __thiscall CFModAudioObject::LoadFile(char const *)" (?LoadFile@CFModAudioObject@@UAEPAVIAudioObject@@PBD@Z) 3>D:\media\desktop\engine4\Engine4\Output\Release Direct3D9\Engine4.exe : fatal error LNK1120: 8 unresolved externals 3>Build log was saved at "file://d:\media\desktop\engine4\Engine4\Engine4\intermediate\Release Direct3D9\BuildLog.htm" 3>Engine4 - 9 error(s), 0 warning(s) ========== Build: 1 succeeded, 1 failed, 0 up-to-date, 1 skipped ==========
