  • Replace carriage returns and line feeds in out.println?

    - by Mike
    I am a novice coder and I am using the following code to outprint a set of Image keywords and input a "|" between them. <% Set allKeywords = new HashSet(); for (AlbumObject ao : currentObjects) { XmpManager mgr = ao.getXmpManager(); if (mgr != null) { allKeywords.addAll(mgr.getKeywordSet()); } } //get the Iterator Iterator itr = allKeywords.iterator(); while(itr.hasNext()){ String str = itr.next(); out.println(str +"|"); } %> I want the output to be like this: red|blue|green|yellow but it prints out: red| blue| green| yellow which breaks my code. I've tried this: str.replaceAll("\n", ""); str.replaceAll("\r", ""); and str.replaceAll("(?:\\n|\\r)", ""); No luck. I'd really appreciate some help!

  • Why doesn't this work?

    - by Kyle W
    take = raw_input('Please enter the string of numbers that compose code\n\n\t') y = str(take) l = [] for i in xrange(0, len(y), 3):         l.append(str(y[i:i+3])) b = len(l) a = 0 while(a!=b):         c = l[a].replace('444', ' ')         c = l[a].replace('111', 'a')         c = l[a].replace('112', 'b')         c = l[a].replace('113', 'c')         c = l[a].replace('114', 'd')         c = l[a].replace('115', 'e')         etc...         a = a + 1 filename = 'decmes.txt' file = open(filename, 'w') file.write(c) file.close() I can enter anything, just 111 for example and it gives me back the same thing I put in. Maybe it's something dumb, but I can't figure it out.

  • Learning PostgreSql: polymorphism

    - by Alexander Kuznetsov
    Functions in PL/PgSql are polymorphic, which is very different from T-SQL. Demonstrating polymorphism For example, the second CREATE FUNCTION in the following script does not replace the first function - it creates a second one: CREATE OR REPLACE FUNCTION public .GetQuoteOfTheDay ( someNumber INTEGER ) RETURNS VARCHAR AS $body$ BEGIN RETURN 'Say my name.' ; END ; $body$ LANGUAGE plpgsql ; CREATE OR REPLACE FUNCTION public .GetQuoteOfTheDay ( someNumber REAL ) RETURNS VARCHAR AS $body$ BEGIN RETURN...(read more)

  • Context Issue in ASP.NET MVC 3 Unobtrusive Ajax

    - by imran_ku07
        Introduction:          One of the coolest feature you can find in ASP.NET MVC 3 is Unobtrusive Ajax and Unobtrusive Client Validation which separates the javaScript behavior and functionality from the contents of a web page. If you are migrating your ASP.NET MVC 2 (or 1) application to ASP.NET MVC 3 and leveraging the Unobtrusive Ajax feature then you will find that the this context in the callback function is not the same as in ASP.NET MVC 2(or 1). In this article, I will show you the issue and a simple solution.       Description:           The easiest way to understand the issue is to start with an example. Create an ASP.NET MVC 3 application. Then add the following javascript file references inside your page,   <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>             Then add the following lines into your view,   @Ajax.ActionLink("About", "About", new AjaxOptions { OnSuccess = "Success" }) <script type="text/javascript"> function Success(data) { alert(this.innerHTML) } </script>              Next, disable Unobtrusive Ajax feature from web.config,   <add key="UnobtrusiveJavaScriptEnabled" value="false"/>              Then run your application and click the About link, you will see the alert window with "About" message on the screen. This shows that the this context in the callback function is the element which is clicked. Now, let's see what will happen when we leverage Unobtrusive Ajax feature. Now enable Unobtrusive Ajax feature from web.config,     <add key="UnobtrusiveJavaScriptEnabled" value="true"/>              Then run your application again and click the About link again, this time you will see the alert window with "undefined" message on the screen. This shows that the this context in the callback function is not the element which is clicked. Here, this context in the callback function is the Ajax settings object provided by jQuery. This may not be desirable because your callback function may need the this context as the element which triggers the Ajax request. The easiest way to make the this context as the element which triggers the Ajax request is to add this line in jquery.unobtrusive-ajax.js file just before $.ajax(options) line,   options.context = element;              Then run your application again and click the About link again, you will find that the this context in the callback function remains same whether you use Unobtrusive Ajax or not.       Summary:          In this article I showed you a breaking change and a simple workaround in ASP.NET MVC 3. If you are migrating your application from ASP.NET MVC 2(or 1) to ASP.NET MVC 3 and leveraging Unobtrusive Ajax feature then you need to consider this breaking change. Hopefully you will enjoy this article too.     SyntaxHighlighter.all()

  • Eclipse has multiple issues after JRE-6 (OpenJDK) upgrade

    I'm on 12.04 LTS, and trying to use Eclipse Indigo.

After that (but I cannot swear it is the root cause), I have the following issues in Eclipse: When trying to launch the simplest HelloWorld program (which behaves fine with manual javac/java), I get either nothing or: An internal error occurred during: "Launching HelloWorld". org/eclipse/jdt/debug/core/JDIDebugModel I get an "Error log" tab in the console panel, with an error: Could not create the view: An unexpected exception was thrown. (Follows a consequent NullPointerException stacktrace between sun.util.calendar.ZoneInfoFile.getZoneIDs(ZoneInfoFile.java:785) and org.eclipse.equinox.launcher.Main.main(Main.java:1386)) When trying to access the Installed JREs part of the preferences, I get a popup saying: Unable to create the selected preference page. An error occurred while automatically activating bundle org.eclipse.jdt.debug.ui (162). And the preference tab says An error has occurred when creating this preference page. Until today I had a manually installed Eclipse (one of the official bundles available on their site), I've tried to replace it by the repository version and I get the same errors. What should I do to make Eclipse work again? Another person reports: Same happened to me after updating last night. Already tried reinstalling Eclipse and Java, starting Eclipse with -clean and starting new workspace and new .eclipse dir, but nothing helps.

  • Merging paragraphs in MS Word 2007

    - by Rajneesh Jain
    My name is Rajneesh Jain from New Delhi, India. I saw your code on merging and re-formatting paragraphs in MS Word 2007. I am facing problem of text overflow. The code I used is: Sub FixParagraph() ' ' FixParagraph Macro ' ' Dim selectedText As String Dim textLength As Integer selectedText = Selection.Text ' If no text is selected, this prevents this subroutine from typing another ' copy of the character following the cursor into the document If Len(selectedText) <= 1 Then Exit Sub End If ' Replace all carriage returns and line feeds in the selected text with spaces selectedText = Replace(selectedText, vbCr, " ") selectedText = Replace(selectedText, vbLf, " ") ' Get rid of repeated spaces Do textLength = Len(selectedText) selectedText = Replace(selectedText, " ", " ") Loop While textLength <> Len(selectedText) ' Replace the selected text in the document with the modified text Selection.TypeText (selectedText) End Sub

  • What's the best practice for async APIs that return futures on Scala?

    - by Maurício Linhares
    I have started a project to write an async PostgreSQL driver on Scala and to be async, I need to accept callbacks and use futures, but then accepting a callback and a future makes the code cumbersome because you always have to send a callback even if it is useless. Here's a test: "insert a row in the database" in { withHandler { (handler, future) => future.get(5, TimeUnit.SECONDS) handler.sendQuery( this.create ){ query => }.get( 5, TimeUnit.SECONDS ) handler.sendQuery( this.insert ){ query => }.get( 5, TimeUnit.SECONDS ).rowsAffected === 1 } } Sending the empty callback is horrible but I couldn't find a way to make it optional or anything like that, so right now I don't have a lot of ideas on how this external API should look like. It could be something like: handler.sendQuery( this.create ).addListener { query => println(query) } But then again, I'm not sure how people are organizing API's in this regard. Providing examples in other projects would also be great.

  • Best way to prevent UIPanGestureRecognizer from firing when moving sprites in cocos2d

    - by cjroebuck
    Im using UIPanGestureRecognizer in my cocos2d game to do drag and drop of sprites. I have a row of sprites and when I drag a sprite on top of another one, the sprite underneath it and any other sprites between should shift left or right out of the way to allow space to drop the currently selected sprite. This is working ok, however, if I am too quick at dragging the sprite around the screen, this triggers another round of the UIPanGestureRecognizer's callback method, and screws up the logic, as the sprites are in-between shifting. I need a way to freeze the callback from firing, whilst the other sprites are shifting, then once they have finished moving, re-enable the callback to fire. Whats the best way to do this?

  • Ad-hoc String Manipulation With Visual Studio

    - by Liam McLennan
    Visual studio supports relatively advanced string manipulation via the ‘Quick Replace’ dialog. Today I had a requirement to modify some html, replacing line breaks with unordered list items. For example, I need to convert: Infrastructure<br/> Energy<br/> Industrial development<br/> Urban growth<br/> Water<br/> Food security<br/> to: <li>Infrastructure</li> <li>Energy</li> <li>Industrial development</li> <li>Urban growth</li> <li>Water</li> <li>Food security</li> This cannot be done with a simple search-and-replace but it can be done using the Quick Replace regular expression support. To use regular expressions expand ‘Find Options’, check ‘Use:’ and select ‘Regular Expressions’ Typically, Visual Studio regular expressions use a different syntax to every other regular expression engine. We need to use a capturing group to grab the text of each line so that it can be included in the replacement. The syntax for a capturing group is to replace the part of the expression to be captured with { and }. So my regular expression: {.*}\<br/\> means capture all the characters before <br/>. Note that < and > have to be escaped with \. In the replacement expression we can use \1 to insert the previously captured text. If the search expression had a second capturing group then its text would be available in \2 and so on. Visual Studio’s quick replace feature can be scoped to a selection, the current document, all open documents or every document in the current solution.

  • Is there a command-line utility app which can locate a specific block of lines in a text file?

    - by fred.bear
    The text "search and replace" utility programs I've seen, seem to only search on a line-by-line basis... Is there a command-line tool which can locate one block of lines (in a text file), and replace it with another block of lines.? For example: Does the test file file contain this exact group of lines: 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe: All mimsy were the borogoves, And the mome raths outgrabe. 'Beware the Jabberwock, my son! The jaws that bite, the claws that catch! Beware the Jubjub bird, and shun The frumious Bandersnatch!' I want this, so that I can replace multiple lines of text in a file and know I'm not overwriting the wrong lines. I would never replace "The Jabberwocky" (Lewis Carroll), but it makes a novel example :)

  • Callbacks: when to return value, and when to modify parameter?

    - by MarkN
    When writing a callback, when is best to have the callback return a value, and when is it best to have the callback modify a parameter? Is there a difference? For example, if we wanted to grab a list of dependencies, when would you do this: function GetDependencies(){ return [{"Dep1" : 1.1}, {"Dept2": 1.2}, {"Dep3" : 1.3}]; } And when would you do this? function RegisterDependencies(register){ register.add("Dep1", 1.1); register.add("Dep2", 1.2); register.add("Dep3", 1.3); }

  • Which part of this simple script is breaking internet explorer?

    I'm writing a simple virtual keyboard for Arabic (indic) digits. Just links that, when clicked, produce the corresponding Unicode Indic character.

  • Manipulating columns of numbers in elisp

    - by ~unutbu
    I have text files with tables like this: Investment advisory and related fees receivable (161,570 ) (71,739 ) (73,135 ) Net purchases of trading investments (93,261 ) (30,701 ) (11,018 ) Other receivables 61,216 (10,352 ) (69,313 ) Restricted cash 20,658 (20,658 ) - Other current assets (39,643 ) 14,752 64 Other non-current assets 71,896 (26,639 ) (26,330 ) Since these are accounting numbers, parenthesized numbers indicate negative numbers. Dashes represent 0 or no number. I'd like to be able to mark a rectangular region such as third column above, call a function (format-column), and automatically have (-73135-11018-69313+64-26330)/1000 sitting in my kill-ring. Even better would be -73.135-11.018-69.313+0.064-26.330 but I couldn't figure out a way to transform 64 -- 0.064. This is what I've come up with: (defun format-column () "format accounting numbers in a rectangular column. format-column puts the result in the kill-ring" (interactive) (let ((p (point)) (m (mark)) ) (copy-rectangle-to-register 0 (min m p) (max m p) nil) (with-temp-buffer (insert-register 0) (goto-char (point-min)) (while (search-forward "-" nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward "," nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward ")" nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward "(" nil t) (replace-match "-" nil t) (just-one-space) (delete-backward-char 1) ) (goto-char (point-min)) (while (search-forward "\n" nil t) (replace-match " " nil t)) (goto-char (point-min)) (kill-new (mapconcat 'identity (split-string (buffer-substring (point-min) (point-max))) "+")) (kill-region (point-min) (point-max)) (insert "(") (yank 2) (goto-char (point-min)) (while (search-forward "+-" nil t) (replace-match "-" nil t)) (goto-char (point-max)) (insert ")/1000") (kill-region (point-min) (point-max)) ) ) ) (global-set-key "\C-c\C-f" 'format-column) Although it seems to work, I'm sure this function is poorly coded. The repetitive calls to goto-char, search-forward, and replace-match and the switching from buffer to string and back to buffer seems ugly and inelegant. My entire approach may be wrong-headed, but I don't know enough elisp to make this more beautiful. Do you see a better way to write format-column, and/or could you make suggestions on how to improve this code?

  • Regex For Finding Ctypes with Int32

    - by Stefan H
    (Hey all, I am looking for a little regex help... I am trying to find all CType(expression,Int32) s and replace them with CInt(expression) This, however, is proving quite difficult, considering there could be a nested Ctype(expression, Int32) within the regex match. Does anyone have any ideas for how to best go about doing this? Here is what I have now: Dim str As String = "CType((original.Width * CType((targetSize / CType(original.Height, Single)), Single)), Int32)" Dim exp As New Regex("CType\((.+), Int32\)") str = exp.Replace(str, "CInt($1)") But this will match the entire string and replace it. I was thinking of doing a recursive function to find the outer most match, and then work inwards, but that still presents a problem with things like CType(replaceChars(I), Int32)), Chr(CType(replacementChars(I), Int32) Any tips would be appreciated. Input returnString.Replace(Chr(CType(replaceChars(I), Int32)), Chr(CType(replacementChars(I), Int32))) Output: returnString.Replace(Chr(CInt(replaceChars(I))),Chr(CInt(replacementChars(I)))) Edit: Been working on it a little more and have a recursive function that I'm still working out the kinks in. Recursion + regex. it kinda hurts. Private Function FindReplaceCInts(ByVal strAs As String) As String System.Console.WriteLine(String.Format("Testing : {0}", strAs)) Dim exp As New Regex("CType\((.+), Int32\)") If exp.Match(strAs).Success Then For Each match As Match In exp.Matches(strAs) If exp.Match(match.Value.Substring(2)).Success Then Dim replaceT As String = match.Value.Substring(2) Dim Witht As String = FindReplaceCInts(match.Value.Substring(2)) System.Console.WriteLine(strAs.IndexOf(replaceT)) strAs.Replace(replaceT, Witht) End If Next strAs = exp.Replace(strAs, "CInt($1)") End If Return strAs End Function Cheers,

  • How to append \line into RTF using RichTextBox control

    - by Steve Sheldon
    When using the Microsoft RichTextBox control it is possible to add new lines like this... richtextbox.AppendText(System.Environment.NewLine); // appends \r\n However, if you now view the generated rtf the \r\n characters are converted to \par not \line How do I insert a \line control code into the generated RTF? What does't work: Token Replacement Hacks like inserting a token at the end of the string and then replacing it after the fact, so something like this: string text = "my text"; text = text.Replace("||" "|"); // replace any '|' chars with a double '||' so they aren't confused in the output. text = text.Replace("\r\n", "_|0|_"); // replace \r\n with a placeholder of |0| richtextbox.AppendText(text); string rtf = richtextbox.Rtf; rtf.Replace("_|0|_", "\\line"); // replace placeholder with \line rtf.Replace("||", "|"); // set back any || chars to | This almost worked, it breaks down if you have to support right to left text as the right to left control sequence always ends up in the middle of the placeholder. Sending Key Messages public void AppendNewLine() { Keys[] keys = new Keys[] {Keys.Shift, Keys.Return}; SendKeys(keys); } private void SendKeys(Keys[] keys) { foreach(Keys key in keys) { SendKeyDown(key); } } private void SendKeyDown(Keys key) { user32.SendMessage(this.Handle, Messages.WM_KEYDOWN, (int)key, 0); } private void SendKeyUp(Keys key) { user32.SendMessage(this.Handle, Messages.WM_KEYUP, (int)key, 0); } This also ends up being converted to a \par Is there a way to post a messaged directly to the msftedit control to insert a control character? I am totally stumped, any ideas guys? Thanks for your help!

'.' + x[1] : ''; var rgx = /(\d+)(\d{3})/; while (rgx.test(x1)) x1 = x1.replace(rgx, '$1' + ',' + '$2'); return x1 + x2; } Now same here I need to restrict user to enter not morethan 5 digits after decimal (ex: Allow: 12,23,221.34323 Not Allow: 12,23,232.232423 I can change above javascript to work that?

  • Understanding C# async / await (1) Compilation

    - by Dixin
    Now the async / await keywords are in C#. Just like the async and ! in F#, this new C# feature provides great convenience. There are many nice documents talking about how to use async / await in specific scenarios, like using async methods in ASP.NET 4.5 and in ASP.NET MVC 4, etc. In this article we will look at the real code working behind the syntax sugar. According to MSDN: The async modifier indicates that the method, lambda expression, or anonymous method that it modifies is asynchronous. Since lambda expression / anonymous method will be compiled to normal method, we will focus on normal async method. Preparation First of all, Some helper methods need to make up. internal class HelperMethods { internal static int Method(int arg0, int arg1) { // Do some IO. WebClient client = new WebClient(); Enumerable.Repeat("http://weblogs.asp.net/dixin", 10) .Select(client.DownloadString).ToArray(); int result = arg0 + arg1; return result; } internal static Task<int> MethodTask(int arg0, int arg1) { Task<int> task = new Task<int>(() => Method(arg0, arg1)); task.Start(); // Hot task (started task) should always be returned. return task; } internal static void Before() { } internal static void Continuation1(int arg) { } internal static void Continuation2(int arg) { } } Here Method() is a long running method doing some IO. Then MethodTask() wraps it into a Task and return that Task. Nothing special here. Await something in async method Since MethodTask() returns Task, let’s try to await it: internal class AsyncMethods { internal static async Task<int> MethodAsync(int arg0, int arg1) { int result = await HelperMethods.MethodTask(arg0, arg1); return result; } } Because we used await in the method, async must be put on the method. Now we get the first async method. According to the naming convenience, it is named MethodAsync. Of course a async method can be awaited. So we have a CallMethodAsync() to call MethodAsync(): internal class AsyncMethods { internal static async Task<int> CallMethodAsync(int arg0, int arg1) { int result = await MethodAsync(arg0, arg1); return result; } } After compilation, MethodAsync() and CallMethodAsync() becomes the same logic. This is the code of MethodAsyc(): internal class CompiledAsyncMethods { [DebuggerStepThrough] [AsyncStateMachine(typeof(MethodAsyncStateMachine))] // async internal static /*async*/ Task<int> MethodAsync(int arg0, int arg1) { MethodAsyncStateMachine methodAsyncStateMachine = new MethodAsyncStateMachine() { Arg0 = arg0, Arg1 = arg1, Builder = AsyncTaskMethodBuilder<int>.Create(), State = -1 }; methodAsyncStateMachine.Builder.Start(ref methodAsyncStateMachine); return methodAsyncStateMachine.Builder.Task; } } It just creates and starts a state machine, MethodAsyncStateMachine: [CompilerGenerated] [StructLayout(LayoutKind.Auto)] internal struct MethodAsyncStateMachine : IAsyncStateMachine { public int State; public AsyncTaskMethodBuilder<int> Builder; public int Arg0; public int Arg1; public int Result; private TaskAwaiter<int> awaitor; void IAsyncStateMachine.MoveNext() { try { if (this.State != 0) { this.awaitor = HelperMethods.MethodTask(this.Arg0, this.Arg1).GetAwaiter(); if (!this.awaitor.IsCompleted) { this.State = 0; this.Builder.AwaitUnsafeOnCompleted(ref this.awaitor, ref this); return; } } else { this.State = -1; } this.Result = this.awaitor.GetResult(); } catch (Exception exception) { this.State = -2; this.Builder.SetException(exception); return; } this.State = -2; this.Builder.SetResult(this.Result); } [DebuggerHidden] void IAsyncStateMachine.SetStateMachine(IAsyncStateMachine param0) { this.Builder.SetStateMachine(param0); } } The generated code has been refactored, so it is readable and can be compiled. Several things can be observed here: The async modifier is gone, which shows, unlike other modifiers (e.g. static), there is no such IL/CLR level “async” stuff. It becomes a AsyncStateMachineAttribute. This is similar to the compilation of extension method. The generated state machine is very similar to the state machine of C# yield syntax sugar. The local variables (arg0, arg1, result) are compiled to fields of the state machine. The real code (await HelperMethods.MethodTask(arg0, arg1)) is compiled into MoveNext(): HelperMethods.MethodTask(this.Arg0, this.Arg1).GetAwaiter(). CallMethodAsync() will create and start its own state machine CallMethodAsyncStateMachine: internal class CompiledAsyncMethods { [DebuggerStepThrough] [AsyncStateMachine(typeof(CallMethodAsyncStateMachine))] // async internal static /*async*/ Task<int> CallMethodAsync(int arg0, int arg1) { CallMethodAsyncStateMachine callMethodAsyncStateMachine = new CallMethodAsyncStateMachine() { Arg0 = arg0, Arg1 = arg1, Builder = AsyncTaskMethodBuilder<int>.Create(), State = -1 }; callMethodAsyncStateMachine.Builder.Start(ref callMethodAsyncStateMachine); return callMethodAsyncStateMachine.Builder.Task; } } CallMethodAsyncStateMachine has the same logic as MethodAsyncStateMachine above. The detail of the state machine will be discussed soon. Now it is clear that: async /await is a C# language level syntax sugar. There is no difference to await a async method or a normal method. As long as a method returns Task, it is awaitable. State machine and continuation To demonstrate more details in the state machine, a more complex method is created: internal class AsyncMethods { internal static async Task<int> MultiCallMethodAsync(int arg0, int arg1, int arg2, int arg3) { HelperMethods.Before(); int resultOfAwait1 = await MethodAsync(arg0, arg1); HelperMethods.Continuation1(resultOfAwait1); int resultOfAwait2 = await MethodAsync(arg2, arg3); HelperMethods.Continuation2(resultOfAwait2); int resultToReturn = resultOfAwait1 + resultOfAwait2; return resultToReturn; } } In this method: There are multiple awaits. There are code before the awaits, and continuation code after each await After compilation, this multi-await method becomes the same as above single-await methods: internal class CompiledAsyncMethods { [DebuggerStepThrough] [AsyncStateMachine(typeof(MultiCallMethodAsyncStateMachine))] // async internal static /*async*/ Task<int> MultiCallMethodAsync(int arg0, int arg1, int arg2, int arg3) { MultiCallMethodAsyncStateMachine multiCallMethodAsyncStateMachine = new MultiCallMethodAsyncStateMachine() { Arg0 = arg0, Arg1 = arg1, Arg2 = arg2, Arg3 = arg3, Builder = AsyncTaskMethodBuilder<int>.Create(), State = -1 }; multiCallMethodAsyncStateMachine.Builder.Start(ref multiCallMethodAsyncStateMachine); return multiCallMethodAsyncStateMachine.Builder.Task; } } It creates and starts one single state machine, MultiCallMethodAsyncStateMachine: [CompilerGenerated] [StructLayout(LayoutKind.Auto)] internal struct MultiCallMethodAsyncStateMachine : IAsyncStateMachine { public int State; public AsyncTaskMethodBuilder<int> Builder; public int Arg0; public int Arg1; public int Arg2; public int Arg3; public int ResultOfAwait1; public int ResultOfAwait2; public int ResultToReturn; private TaskAwaiter<int> awaiter; void IAsyncStateMachine.MoveNext() { try { switch (this.State) { case -1: HelperMethods.Before(); this.awaiter = AsyncMethods.MethodAsync(this.Arg0, this.Arg1).GetAwaiter(); if (!this.awaiter.IsCompleted) { this.State = 0; this.Builder.AwaitUnsafeOnCompleted(ref this.awaiter, ref this); } break; case 0: this.ResultOfAwait1 = this.awaiter.GetResult(); HelperMethods.Continuation1(this.ResultOfAwait1); this.awaiter = AsyncMethods.MethodAsync(this.Arg2, this.Arg3).GetAwaiter(); if (!this.awaiter.IsCompleted) { this.State = 1; this.Builder.AwaitUnsafeOnCompleted(ref this.awaiter, ref this); } break; case 1: this.ResultOfAwait2 = this.awaiter.GetResult(); HelperMethods.Continuation2(this.ResultOfAwait2); this.ResultToReturn = this.ResultOfAwait1 + this.ResultOfAwait2; this.State = -2; this.Builder.SetResult(this.ResultToReturn); break; } } catch (Exception exception) { this.State = -2; this.Builder.SetException(exception); } } [DebuggerHidden] void IAsyncStateMachine.SetStateMachine(IAsyncStateMachine stateMachine) { this.Builder.SetStateMachine(stateMachine); } } Once again, the above state machine code is already refactored, but it still has a lot of things. More clean up can be done if we only keep the core logic, and the state machine can become very simple: [CompilerGenerated] [StructLayout(LayoutKind.Auto)] internal struct MultiCallMethodAsyncStateMachine : IAsyncStateMachine { // State: // -1: Begin // 0: 1st await is done // 1: 2nd await is done // ... // -2: End public int State; public TaskCompletionSource<int> ResultToReturn; // int resultToReturn ... public int Arg0; // int Arg0 public int Arg1; // int arg1 public int Arg2; // int arg2 public int Arg3; // int arg3 public int ResultOfAwait1; // int resultOfAwait1 ... public int ResultOfAwait2; // int resultOfAwait2 ... private Task<int> currentTaskToAwait; /// <summary> /// Moves the state machine to its next state. /// </summary> public void MoveNext() // IAsyncStateMachine member. { try { switch (this.State) { // Original code is split by "await"s into "case"s: // case -1: // HelperMethods.Before(); // MethodAsync(Arg0, arg1); // case 0: // int resultOfAwait1 = await ... // HelperMethods.Continuation1(resultOfAwait1); // MethodAsync(arg2, arg3); // case 1: // int resultOfAwait2 = await ... // HelperMethods.Continuation2(resultOfAwait2); // int resultToReturn = resultOfAwait1 + resultOfAwait2; // return resultToReturn; case -1: // -1 is begin. HelperMethods.Before(); // Code before 1st await. this.currentTaskToAwait = AsyncMethods.MethodAsync(this.Arg0, this.Arg1); // 1st task to await // When this.currentTaskToAwait is done, run this.MoveNext() and go to case 0. this.State = 0; MultiCallMethodAsyncStateMachine that1 = this; // Cannot use "this" in lambda so create a local variable. this.currentTaskToAwait.ContinueWith(_ => that1.MoveNext()); break; case 0: // Now 1st await is done. this.ResultOfAwait1 = this.currentTaskToAwait.Result; // Get 1st await's result. HelperMethods.Continuation1(this.ResultOfAwait1); // Code after 1st await and before 2nd await. this.currentTaskToAwait = AsyncMethods.MethodAsync(this.Arg2, this.Arg3); // 2nd task to await // When this.currentTaskToAwait is done, run this.MoveNext() and go to case 1. this.State = 1; MultiCallMethodAsyncStateMachine that2 = this; this.currentTaskToAwait.ContinueWith(_ => that2.MoveNext()); break; case 1: // Now 2nd await is done. this.ResultOfAwait2 = this.currentTaskToAwait.Result; // Get 2nd await's result. HelperMethods.Continuation2(this.ResultOfAwait2); // Code after 2nd await. int resultToReturn = this.ResultOfAwait1 + this.ResultOfAwait2; // Code after 2nd await. // End with resultToReturn. this.State = -2; // -2 is end. this.ResultToReturn.SetResult(resultToReturn); break; } } catch (Exception exception) { // End with exception. this.State = -2; // -2 is end. this.ResultToReturn.SetException(exception); } } /// <summary> /// Configures the state machine with a heap-allocated replica. /// </summary> /// <param name="stateMachine">The heap-allocated replica.</param> [DebuggerHidden] public void SetStateMachine(IAsyncStateMachine stateMachine) // IAsyncStateMachine member. { // No core logic. } } Only Task and TaskCompletionSource are involved in this version. And MultiCallMethodAsync() can be simplified to: [DebuggerStepThrough] [AsyncStateMachine(typeof(MultiCallMethodAsyncStateMachine))] // async internal static /*async*/ Task<int> MultiCallMethodAsync(int arg0, int arg1, int arg2, int arg3) { MultiCallMethodAsyncStateMachine multiCallMethodAsyncStateMachine = new MultiCallMethodAsyncStateMachine() { Arg0 = arg0, Arg1 = arg1, Arg2 = arg2, Arg3 = arg3, ResultToReturn = new TaskCompletionSource<int>(), // -1: Begin // 0: 1st await is done // 1: 2nd await is done // ... // -2: End State = -1 }; multiCallMethodAsyncStateMachine.MoveNext(); // Original code are moved into this method. return multiCallMethodAsyncStateMachine.ResultToReturn.Task; } Now the whole state machine becomes very clean - it is about callback: Original code are split into pieces by “await”s, and each piece is put into each “case” in the state machine. Here the 2 awaits split the code into 3 pieces, so there are 3 “case”s. The “piece”s are chained by callback, that is done by Builder.AwaitUnsafeOnCompleted(callback), or currentTaskToAwait.ContinueWith(callback) in the simplified code. A previous “piece” will end with a Task (which is to be awaited), when the task is done, it will callback the next “piece”. The state machine’s state works with the “case”s to ensure the code “piece”s executes one after another. Callback If we focus on the point of callback, the simplification  can go even further – the entire state machine can be completely purged, and we can just keep the code inside MoveNext(). Now MultiCallMethodAsync() becomes: internal static Task<int> MultiCallMethodAsync(int arg0, int arg1, int arg2, int arg3) { TaskCompletionSource<int> taskCompletionSource = new TaskCompletionSource<int>(); try { // Oringinal code begins. HelperMethods.Before(); MethodAsync(arg0, arg1).ContinueWith(await1 => { int resultOfAwait1 = await1.Result; HelperMethods.Continuation1(resultOfAwait1); MethodAsync(arg2, arg3).ContinueWith(await2 => { int resultOfAwait2 = await2.Result; HelperMethods.Continuation2(resultOfAwait2); int resultToReturn = resultOfAwait1 + resultOfAwait2; // Oringinal code ends. taskCompletionSource.SetResult(resultToReturn); }); }); } catch (Exception exception) { taskCompletionSource.SetException(exception); } return taskCompletionSource.Task; } Please compare with the original async / await code: HelperMethods.Before(); int resultOfAwait1 = await MethodAsync(arg0, arg1); HelperMethods.Continuation1(resultOfAwait1); int resultOfAwait2 = await MethodAsync(arg2, arg3); HelperMethods.Continuation2(resultOfAwait2); int resultToReturn = resultOfAwait1 + resultOfAwait2; return resultToReturn; Yeah that is the magic of C# async / await: Await is not to wait. In a await expression, a Task object will be return immediately so that execution is not blocked. The continuation code is compiled as that Task’s callback code. When that task is done, continuation code will execute. Please notice that many details inside the state machine are omitted for simplicity, like context caring, etc. If you want to have a detailed picture, please do check out the source code of AsyncTaskMethodBuilder and TaskAwaiter.

  • Apache2, FastCGI, PHP-FPM, APC on virtualmin panel with nginx front end reverse proxy

    - by Ünsal Korkmaz
    My dream setup: php 5.3.6 + mysql 5.5.10 on Apache2, FastCGI, PHP-FPM, APC with nginx 1.0 front end reverse proxy. And as free server management panel: Virtualmin GPL on centos 5.6 In a new centos 5.6 setup. Using this code for installing virtualmin: wget http://software.virtualmin.com/gpl/scripts/install.sh chmod +x install.sh ./install.sh After setup, i see php is 5.1 and mysql is 5.0 version. And system not supporting php-fpm but supporting fcgid wrapper. I did following changes: wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1.0-6.ius.el5.noarch.rpm wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm rpm -Uvh ius-release*.rpm epel-release*.rpm yum install yum-plugin-replace yum remove mysql.i386 yum replace mysql --replace-with mysql55 service mysqld restart chkconfig mysqld on mysql_upgrade --password=1234 yum replace php --replace-with php53u yum install php53u-fpm php53u-pecl-apc service httpd restart chkconfig php-fpm on service php-fpm start I am not sure why virtualmin installing both mysql.i386 and 64 bit version together but needed to remove one of them for using yum replace. So i had php 5.3.6 + mysql 5.5.10 with PHP-FPM, APC installed. But virtualmin not supporting PHP-FPM + fastcgi and its still running on fcgid. I am ultra newbie on server management so i couldnt find workaround after this. I want to switch fcgid wrapper to PHP-FPM + fastcgi at least for 1 virtual server. And if i can find a fix for this section, i want to setup nginx 1.0 as front end reverse proxy for serving static files and passing php files to apache. http://nginxcp.com/ is what i want but its for cpanel.
