• I have a ConnectException that isn't being caught for some reason

  - by aakbari1024

  I'm working on an Android application that uses sockets. I have a function called initializeStreams() which opens the socket and attempts a connection. This function throws a ConnectException if the connection could not be established. But for some reason, in the code that calls initializeStreams(), which has a catch block for ConnectException, the log prints out its own stack trace for the exception instead of going to the catch block. The catch block is never reached at all, even though the exact exception is being thrown. Here's the code: The try block: try { initializeStreams(); /* drivesList = new ArrayList<String>(); drivesList = enumerateDrives();*/ } catch (ConnectException e) { //Log.i(TAG, "caught connect exception"); /*loadingProgress.dismiss(); retryConnection();*/ } initializeStreams(): public void initializeStreams() throws ConnectException { try { Log.i(TAG, "Attempting to connect"); requestSocket = new Socket(SERVER_ADDR, PORT); /* other code */ } catch (IOException e) { e.printStackTrace(); } I can't figure this out, so any help would be much appreciated. }

• How do I detect a file write error in C?

  - by rich

  I have an embedded environment where a user might insert or remove a USB flash drive. I would like to know if the drive has been removed, or if there is some other problem when I try to write to the drive. However, Linux just saves the information in its buffers and returns with no indicated error. The computer I'm using comes with a 2.4.26 kernel and libc 2.3.2. I'm mounting the drive this way: i = mount(MEMORY_DEV_PATH, MEMORY_MNT_PATH, "vfat", MS_SYNCHRONOUS, NULL); That works: 50:/root # mount /dev/scsi/host0/bus0/target0/lun0/part1 on /mem type vfat (rw,sync) 50:/root # Later, I try to copy a file to it: int ifile, ofile; ifile = open("/tmp/tmpmidi.mid", O_RDONLY); if (ifile < 0) { perror("open in"); break; } ofile = open(current_file_name.c_str(), O_WRONLY | O_SYNC); if (ofile < 0) { perror("open out"); break; } #define BUFSZ 256 char buffer[BUFSZ]; while (1) { i = read(ifile, buffer, BUFSZ); if (i < 0) { perror("read"); break; } j = write(ofile, buffer, i); if (j < 0) { perror("write"); break; } if (i != j) { perror("Sizes wrong"); break; } if (i < BUFSZ) { printf("Copy is finished, I hope\n"); close(ifile); close(ofile); break; } } If this snippet of code is executed with a write-protected USB memory, the result is Copy is finished, I hope amid a flurry of error messages from the kernel on the console. I believe the same thing would happen if I simply removed the USB drive (without unmounting it). I have also fiddled with devfs. I figured out how to get it to automatically mount the drive, (with the REGISTER event) but it never seems to trigger the UNREGISTER when I pull out the memory. How can I determine in my program whether I have successfully created a file? Update 4 July: It was a silly oversight of me not to check the result from close(). Unfortunately, the file can be closed without error. So that didn't help. What about fsync()? That sounds like a good idea, but that didn't catch the error either. There might be some interesting information in /sys if I had such a thing. I believe that didn't get added until 2.6.?. The comment(s) about the quality of my flash drive are probably justified. It's one of the earlier ones. In fact, write protect switches seem to be extremely rare these days. I think I have to use the overkill option: Create a file, unmount & remount the drive, and check to see if the file is there. If that doesn't solve my problem, then something is really messed up! Note to myself: Make sure the file you try to create isn't already there! By the way, this does happen to be a C++ program. You can tell by the .c_str() which I had intended to edit out for simplicity.

• How can I most accurately calculate the execution time of an ASP.NET page while also displaying it o

  - by henningst

  I want to calculate the execution time of my ASP.NET pages and display it on the page. Currently I'm calculating the execution time using a System.Diagnostics.Stopwatch and then store the value in a log database. The stopwatch is started in OnInit and stopped in OnPreRenderComplete. This seems to be working quite fine, and it's giving a similar execution time as the one shown in the page trace. The problem now is that I'm not able to display the execution time on the page because the stopwatch is stopped too late in the life cycle. What is the best way to do this?

• LinkDemand error on webserver when using TrackSource

  - by robertpnl

  Hi, On a webserver (shared hosting provider) I published a website with a ADO.Net Framework model in use with MySql Connector 6.3.1. When I request a page, a Security Exception will be happen with this error messages: "LinkDemand The type of the first permission that failed was: System.Security.Permissions.SecurityPermission The Zone of the assembly that failed was: MyComputer ". This exception raised when code collect the listeners of a tracksource: public class MySqlTrace { private static TraceSource source = new TraceSource("mysql"); static MySqlTrace() { foreach (TraceListener listener in source.Listeners) // <-- Exception throw here { // ... } } } The web.config doesn't have any trace data or system.diagnostics. My question is, why will a get a LinkDemand security exception during collecting the source listeners. What can maybe be wrong in here?

• Best practice for handling memory leaks in large Java projects?

  - by knorv

  In almost all larger Java projects I've been involved with I've noticed that the quality of service of the application degrades with the uptime of the container. This is most probably due to memory leaks in the code. The correct way to solve this problem is obviously to trace back to the root cause of the problem and fix the leaks in the code. The quick and dirty way of solving the problem is simply restarting Tomcat (or whichever servlet container you're using). These are my three questions: Assume that you choose to solve the problem by tracing the root cause of the problem (the memory leaks), how would you collect data to zoom in on the problem? Assume that you choose the quick and dirty way of speeding things up by simply restarting the container, how would you collect data to choose the optimal restart cycle? Have you been able to deploy and run projects over an extended period of time without ever restarting the servlet container to regain snappiness? Or is an occasional servlet restart something that one has to simply accept?

• Using ActiveRecord::Base.transaction in a rake task?

  - by Brian Jordan

  I am writing a rake task which, at one point, uses a custom YAML file import method to seed the database. At one point in the import code, I have: ActiveRecord::Base.transaction do Trying to run the rake task throws: You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] The stack trace points to the aforementioned line in the code. Is there a way to instantiate ActiveRecord::Base during a rake task? Thanks!

• Small footprint on a Laptop

  - by sqldebacle

  I am trying to find a solution where I can do the following: 1) Run a small footprint on my laptop 2) Run virtual instances of OS w/ no primary OS installed. All the OS that I will ever use will be all virtualized. I tried playing around with the VMware Esxi, and got it to boot it from the flash drive, etc. But this just runs the server. I cannot actually run my virtual instances from there. Anyone has done this? Something similar implemented with VMWare products without needing 2 computers will be great. Thanks, -Subhash

• Is there a faster method then StringBuilder for a max 9-10 step string concatenation?

  - by Pentium10

  I have this code to concate some array elements: StringBuilder sb = new StringBuilder(); private RatedMessage joinMessage(int step, boolean isresult) { sb.delete(0, sb.length()); for (int i = 0; i <= step; i++) { if (mStack[i] == null) continue; rm = mStack[i].getCurrentMsg(); if (rm == null || rm.msg.length() == 0) continue; if (sb.length() != 0) { sb.append(", "); } sb.append(rm.msg); } return sb.toString(); } Important the array holds max 10 items, so it's not quite much. My trace output tells me this method is called 18864 times, 16% of the runtime was spent in this method. Can I optimize more?

• Can't unlock locked screen, in Ubuntu 12

  - by Camille Goudeseune

  After locking the screen (with a keystroke bound to xlock -nice 8 -mode blank), I can unlock the screen as expected, but only within a few minutes. After being locked overnight, when I hit a key (even Ctrl+Alt combos), the screen stays black with just a brief white flash across the middle of both monitors. The workaround is to ssh in from another host and restart X. Some months ago, this happened every few weeks. By now it happens almost every morning. How do I even start to diagnose this? What might I look for in log files? (The intermittency is particularly troubling.) Failing that, is there an alternative to xlock aka xlockmore? Hardware: 3-year-old HP minitower, GEForce 9800 GT, two Asus LCD monitors. Software: Ubuntu 12.04.2 LTS. Window manager awesome-wm. NVidia driver 304.88. XLock version xlockmore-5.31.

• Nested for loop error with !null checking an element that doesn't exist

  - by Programatt

  I am currently using nested for loops in a 2D array of size 4,2. When I run my program, I get index out of bounds Exception on the following line else if (state[i][j+1] != null && state[i][j].getFlash() <= state[i][j].getCycleLength() && state[i][j+1].getCycleLength() == state[i][j].getCycleLength()){ } It says the index out of bounds is 2. I would understand the error if I wasn't checking to see if [i][j+1] wasn't null, but I don't understand the exception with the check? I tried moving around the !null check but the program still fails on this line. Any help would be greatly appreciated. Stack trace: Exception in thread "Timer-0" java.lang.ArrayIndexOutOfBoundsException: 2 at NatComp.data$1.run(data.java:67) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462)

• Redirect traffic to local address so iOS speedtest app measures LAN speed

  - by ivan_sig

  I have mounted a Speedtest Mini server on a local LAMP, so I can test my LAN speeds effortlessly just by opening the URL with a Flash enabled web browser, the thing is, I want my iOS and Android devices to test with the LAN server too, not with the WAN, as I'm trying to measure LAN-Only performance. Is there a way so I can redirect the traffic intended to an specific external IP (The one of the real server) to my local server?. I know the servers IP as a short Wireshark analysis gave me the data, but still searching for a way to make that redirect. I have Jailbreak and root on my devices, so playing with system files is not a problem. I've tried mounting a proxy and making redirects by the hosts file and domain names, but it looks like Ookla's app relies on IP address only.

• iPhone Wait For Animation Ending

  - by paul simmons

  Hi, In an iPhone application, I try to catch animation endings using setAnimationDidStopSelector. I try to suspend code execution until animation ends. I have tried this; set a global BOOL variable, set it to TRUE before commiting animation and after commiting animations waited using a while loop. In the setAnimationDidStopSelector, set the BOOL variable to FALSE and hope while loop to break. But unluckily this did not work, the code did not even fall into setAnimationDidStopSelector (I check that with some trace outputs). What do you suggest?

• Weird exception with delayed_job

  Trying to queue a job with delayed_job as follows: Delayed::Job.enqueue(BackgroundProcess.new(current_user, object)) current_user and object are not nil when I print them out.

• Seam log4j credential logs

  - by Marc

  In Seam, using log4, I would like to have my info, warn and error always logging the logged in user (if so) name to be logged with whatever the log message is. Being a consistant thing I do not want to have to grab the logged-in user name, and prefix the message. so I attempted to populate the log4j NDC to have it as a field of the log message. Pushing the user name on successful login: NDC.push(credentials.getUsername()); Which works, but the NDC is managed per thread, so once another thread processes a request from the same logged in user, the trace of this user name is lost. I was thinking that there should be a common pattern to accomplish this simple task which is attaching each log message to the logged user, using the NDC or not, to know exactly what user triggered what action. Anyone knows the appropriate way to accomplish this?

• I can't change a value, for a web service using an axiom client!

  - by adrian7

  Hi.I just started learning about web serices. I succesfuly installed Tomcat, and deployed axis2 on it. I followed the tutorial from here http://ws.apache.org/axis2/1_1_1/quickstartguide.html . I made the StockQuoteService web service, moved the .aar file in the WEB-INF/services folder and tested it - it worked all fine. Then I made a client for the servce. I took the source code of the file AXIOMClient.java from the dir described here http://ws.apache.org/axis2/1_1_1/quickstartguide.html#clientaxiom , imported the classes in Eclipse Java IDE and runned it. I tested and the update method works from the browser when calling http://localhost:8080/axis2/services/StockQuoteService/update?symbol=WSO&price=144 But from my java client update method is not working at all, when calling getPrice I always receive 42.00. What am I doing wrong? or, how can I trace what is happening?

• Displaying Nested Array Content with Time Delay in Flex

  - by MooCow

  I have a JSON array that look like this: (array here) I'm trying to use Flex to display each Project and its Milestone elements similar to a nested for-loop for 15 seconds per Milestone element before advancing to the next Project. I was shown a technique that works well for something without another array buried into it. var key:int = 0; var timer:timer = new timer (10000, project.length); timer.addEventListener (TimerEvent.TIMER, function showStuff(event:EVENT):void { trace project[key].projectName; key++; }); timer.start(); But that only replicate a single FOR-LOOP and not a nested FOR-LOOP. Any suggestions?

• Documenting software-updates semi-automatically in MacOS X by parsing log files?

  - by Martin

  I'd like to document changes I made to my computer (running MacOS 10.6.8) to be able to identify the sources of eventual problems. Mostly I install updates when a software notifies me about a newer version and offers me a dialog to download and install the update. Currently I'm documenting those updates "by hand" by noting in a text file, when I have e. g. installed a Flash-Player update or updated another 3rd party software ... I wonder if I could achieve that easier and semi-automatically by parsing system logfiles for certain texts like "install" and that way directly get the relevant information: what has been installed (Software and version) when has been installed where has it been installed/what has changed Is there a way to extract such information by a script from the existing logfiles?

• Dying SanDisk Memory Stick Pro Duo

  - by Different55

  I have a Memory Stick Pro Duo and after attempting to delete the largest file from a Mac the stick has become unusable. I can almost access it. When I put it in my PC I can open/delete/copy/paste/rename/modify one file/folder, then it can't detect the card. If I reinsert the card I can move on to the next file, but this is really annoying and my PSP won't read it at all. The memory card access light will flash for a really long time before it says that every file is corrupted. When I have tried to format it with either the PC, PSP, or a camera that uses a memory stick pro duo, it fails. I've tried with all the different options on windows, I tried formatting it through CMD, but nothing I have tried works. Should I copy every file off one by one or is there a way to fix it?

• iMac with Mountain Lion and Mavericks

  - by bob

  I have been starting up my iMac (Mavericks) with a flash drive that boots up Mountain Lion so that I can use an app that is incompatible with Mavericks. Question: I have a single external backup drive always connected to my Mac. I am thinking of partitioning that drive and giving each partition a unique name, e.g., Backup 1 and Backup 2. I intend then to boot up in Mavericks and tell Time Machine to back up to Backup 1, and then boot up in Mountain Lion and tell Time Machine to back up to Backup 2. Will this work, i.e., will the appropriate partition automatically back up the system in which it is booted?
