  • Python twisted Reactor class

    - by anijhaw
    What is the significance of the decorators @reactor.callWhenRunning, @results_deferred.addCallback @results_deferred.addErrback. Also what are deferred strings, for example in the twisted.internet.utils.getProcessOutput() returns a deferred string what exactly is happening here? I am new to twisted hence this might be a very simple question but reading twisted documentation did not help me much

  • Method for finding memory leak in large Java heap dumps

    - by Rickard von Essen
    I have to find a memory leak in a Java application. I have some experience with this but would like advice on a methodology/strategy for this. Any reference and advice is welcome. About our situation: Heap dumps are larger than 1 GB We have heap dumps from 5 occasions. We don't have any test case to provoke this. It only happens in the (massive) system test environment after at least a weeks usage. The system is built on a internally developed legacy framework with so many design flaws that they are impossible to count them all. Nobody understands the framework in depth. It has been transfered to one guy in India who barely keeps up with answering e-mails. We have done snapshot heap dumps over time and concluded that there is not a single component increasing over time. It is everything that grows slowly. The above points us in the direction that it is the frameworks homegrown ORM system that increases its usage without limits. (This system maps objects to files?! So not really a ORM) Question: What is the methodology that helped you succeed with hunting down leaks in a enterprise scale application?

  • Sysdeo Tomcat DevLoader - Hot deploy of java class causes whole application to restart

    - by Gala101
    Hi, I am using sysdeo tomcat plugin 3.2.1 with eclipse 3.5.1 (Galileo) and tomcat 5.5.23 on windows XP. I can get tomcat plugin working in eclipse, and have extracted devloader.zip into [tomcat]\server\classes. I have also updated the context and now it has this entry: <Context path="/myapp1" reloadable="true" docBase="F:\Work\eclipse_workspace\myapp1" workDir="F:\Work\eclipse_workspace\myapp1\work" > <Logger className="org.apache.catalina.logger.SystemOutLogger" verbosity="4" timestamp="true"/> <Loader className="org.apache.catalina.loader.DevLoader" reloadable="true" debug="1" useSystemClassLoaderAsParent="false" /> </Context> I have activated devloader (in Project Properties Tomcat Devloader Classpath) and have 'checked' all my classes and jars, I haven't 'checked' commons-loggin.jar jsp-api.jar, servlet-api.jar. So on launching tomcat via the plugin, I can get it running with devloader as shown in eclipse console view [DevLoader] Starting DevLoader [DevLoader] projectdir=F:\Work\eclipse_workspace\myapp1 [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/classes/ [DevLoader] added file:/F:/Work/eclipse_workspace/myapp1/WEB-INF/lib/activation.jar However, if I even add a single System.out.println into any java file and save it, the whole application gets reloaded (takes ~80 sec) which is as good as stopping/starting tomcat itself. I've tried adding -Xdebug in JAVA_OPTS in the catalina.bat but no luck :( Can you please guide where I may be doing it wrong.. Please note that I can 'redeploy' the whole application on tomcat but that's not what I need, I am looking to be able to make small changes in java classes 'on-the-fly' while coding/debugging without having to wait for complete app restart. Another annoyance is that restarting tomcat/application causes the session/debug progress to be lost.. Can you please guide me how to go about it. PS: I am not using any ant/maven scripts explicitly, just relying on eclipse to do the build for me (which it does).

  • Trigger element's onclick method with JQuery [ASP.NET]

    - by blu
    I have an ASP.NET server control that inherits from CheckBoxList that renders the controls with a UL and LIs. The control is set to AutoPostBack. Markup: <div id="foo"> <ul> <li> <input type="checkbox" onclick="javascript:setTimeout('__doPostBack(..." ... /> <label ... /> </li> </ul> </div> I would like to trigger the JavaScript that is rendered on the CheckBox when the parent LI is clicked. Here is what I have so far: $("#foo li").click(function() { $(this).find("input:eq(0)").trigger("click"); }); This fires a postback in FF 3.x but the event handler in the codebehind is not fired. In IE 7 a script error comes up and the browser just kind of hangs there for a bit then reloads the page. How should I be doing this?

  • How do you mock a Sealed class?

    - by Brett Veenstra
    Mocking sealed classes can be quite a pain. I currently favor an Adapter pattern to handle this, but something about just keeps feels weird. So, What is the best way you mock sealed classes? Java answers are more than welcome. In fact, I would anticipate that the Java community has been dealing with this longer and has a great deal to offer. But here are some of the .NET opinions: Why Duck Typing Matters for C# Develoepers Creating wrappers for sealed and other types for mocking Unit tests for WCF (and Moq)

  • Generic collection as a Java method argument

    - by Guido
    Is there any way to make this work in Java? public static void change(List<? extends Object> list, int position1, int position2) { Object obj = list.get(position1); list.set(position1, list.get(position2)); list.set(position2, obj); } The only way I've successfully avoided warnings and errors is this: public static <T> T change(List<T> list, int position1, int position2) { T obj = list.get(position1); list.set(position1, list.get(position2)); list.set(position2, obj); return obj; } but I don't like to be forced to return a value.

  • Excel 2003 VBA - Method to duplicate this code that select and colors rows

    - by Justin
    so this is a fragment of a procedure that exports a dataset from access to excel Dim rs As Recordset Dim intMaxCol As Integer Dim intMaxRow As Integer Dim objxls As Excel.Application Dim objWkb As Excel.Workbook Dim objSht As Excel.Worksheet Set rs = CurrentDb.OpenRecordset("qryOutput", dbOpenSnapshot) intMaxCol = rs.Fields.Count If rs.RecordCount > 0 Then rs.MoveLast: rs.MoveFirst intMaxRow = rs.RecordCount Set objxls = New Excel.Application objxls.Visible = True With objxls Set objWkb = .Workbooks.Add Set objSht = objWkb.Worksheets(1) With objSht On Error Resume Next .Range(.Cells(1, 1), .Cells(intMaxRow, intMaxCol)).CopyFromRecordset rs .Name = conSHT_NAME .Cells.WrapText = False .Cells.EntireColumn.AutoFit .Cells.RowHeight = 17 .Cells.Select With Selection.Font .Name = "Calibri" .Size = 10 End With .Rows("1:1").Select With Selection .Insert Shift:=xlDown End With .Rows("1:1").Interior.ColorIndex = 15 .Rows("1:1").RowHeight = 30 .Rows("2:2").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("4:4").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("6:6").Select With Selection.Interior .ColorIndex = 40 .Pattern = xlSolid End With .Rows("1:1").Select With Selection.Borders(xlEdgeBottom) .LineStyle = xlContinuous .Weight = xlMedium .ColorIndex = xlAutomatic End With End With End With End If Set objSht = Nothing Set objWkb = Nothing Set objxls = Nothing Set rs = Nothing Set DB = Nothing End Sub see where I am looking at coloring the rows. I wanted to select and fill (with any color) every other row, kinda like some of those access reports. I can do it manually coding each and every row, but two problems: 1) its a pain 2) i don't know what the record count is before hand. How can I make the code more efficient in this respect while incorporating the recordcount to know how many rows to "loop through" EDIT: Another question I have is with the selection methods I am using in the module, is there a better excel syntax instead of these with selections.... .Cells.Select With Selection.Font .Name = "Calibri" .Size = 10 End With is the only way i figure out how to accomplish this piece, but literally every other time I run this code, it fails. It says there is no object and points to the .font ....every other time? is this because the code is poor, or that I am not closing the xls app in the code? if so how do i do that? Thanks as always!

  • NSURLConnection still calls delegate AFTER cancel method has been called

    - by Shizam
    Hi All, Having a problem with NSURLConnection, if I create a NSURLConnection and call [connection connectionWithRequest] let it load a little then call [connection cancel] most of the time that works fine. However occasionally even after I call [connection cancel] the connection's delegate still gets called (which crashes the app). Googling around it looks like the problem here is a race condition in the runloop, I cancel the connection and release the delegate but before the runloop cycles it calls the delegate functions - crash. Is there a way for me to, after I call [connection cancel] confirm the connection has actually canceled? Even a crappy while() loop will do :(

  • SQLiteDataAdapter Update method returning 0 C#

    - by Lirik
    I loaded 83 rows from my CSV file, but when I try to update the SQLite database I get 0 rows... I can't figure out what I'm doing wrong. The program outputs: Num rows loaded is 83 Num rows updated is 0 The source code is: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited\""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); Console.WriteLine("Num rows loaded is " + ds.Tags.Rows.Count); InsertData(ds, tableName); } } } public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { using (new SQLiteCommandBuilder(sqliteAdapter)) { conn.Open(); Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } } Any hints on why it's not updating the correct number of rows?

  • Why is my addSubview: method causing a leak?

    - by Nathan
    Okay, so I have done a ton of research on this and have been pulling my hair out for days trying to figure out why the following code leaks: [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; UIImage *comicImage = [self getCachedImage:[NSString stringWithFormat:@"%@%@%@",@"http://url/",comicNumber,@".png"]]; self.imageView = [[[UIImageView alloc] initWithImage:comicImage] autorelease]; [self.scrollView addSubview:self.imageView]; self.scrollView.contentSize = self.imageView.frame.size; self.imageWidth = [NSString stringWithFormat:@"%f",imageView.frame.size.width]; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; Both self.imageView and self.scrollView are @propety (nonatomic, retain) and released in my dealloc.. imageView isn't used anywhere else in the code. This code is also run in a thread off of the main thread. If I run this code on my device, it will quickly run out of memory if I continually load this view. However, I've found if I comment out the following line: [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; UIImage *comicImage = [self getCachedImage:[NSString stringWithFormat:@"%@%@%@",@"http://url/",comicNumber,@".png"]]; self.imageView = [[[UIImageView alloc] initWithImage:comicImage] autorelease]; //[self.scrollView addSubview:self.imageView]; self.scrollView.contentSize = self.imageView.frame.size; self.imageWidth = [NSString stringWithFormat:@"%f",imageView.frame.size.width]; [UIApplication sharedApplication].networkActivityIndicatorVisible = NO; Memory usage becomes stable, no matter how many times I load the view. I have gone over everything I can think to see why this is leaking, but as far as I can tell I have all my releases straight. Can anyone see what I am missing?
