• Why is javac 1.5 running so slowly compared with the Eclipse compiler?

  - by Simon Nickerson

  I have a Java Maven project with about 800 source files (some generated by javacc/JTB) which is taking a good 25 minutes to compile with javac. When I changed my pom.xml over to use the Eclipse compiler, it takes about 30 seconds to compile. Any suggestions as to why javac (1.5) is running so slowly? (I don't want to switch over to the Eclipse compiler permanently, as the plugin for Maven seems more than a little buggy.) I have a test case which easily reproduces the problem. The following code generates a number of source files in the default package. If you try to compile ImplementingClass.java with javac, it will seem to pause for an inordinately long time. import java.io.File; import java.io.FileNotFoundException; import java.io.PrintStream; public class CodeGenerator { private final static String PATH = System.getProperty("java.io.tmpdir"); private final static int NUM_TYPES = 1000; public static void main(String[] args) throws FileNotFoundException { PrintStream interfacePs = new PrintStream(PATH + File.separator + "Interface.java"); PrintStream abstractClassPs = new PrintStream(PATH + File.separator + "AbstractClass.java"); PrintStream implementingClassPs = new PrintStream(PATH + File.separator + "ImplementingClass.java"); interfacePs.println("public interface Interface<T> {"); abstractClassPs.println("public abstract class AbstractClass<T> implements Interface<T> {"); implementingClassPs.println("public class ImplementingClass extends AbstractClass<Object> {"); for (int i=0; i<NUM_TYPES; i++) { String nodeName = "Node" + i; PrintStream nodePs = new PrintStream(PATH + File.separator + nodeName + ".java"); nodePs.printf("public class %s { }\n", nodeName); nodePs.close(); interfacePs.printf("void visit(%s node, T obj);%n", nodeName); abstractClassPs.printf("public void visit(%s node, T obj) { System.out.println(obj.toString()); }%n", nodeName); } interfacePs.println("}"); abstractClassPs.println("}"); implementingClassPs.println("}"); interfacePs.close(); abstractClassPs.close(); implementingClassPs.close(); } }

• How to replace all id attributes of a child collection of complex types using jQuery in ASP.net MVC

  - by TJB

  Here's my situation: I'm writing an ASP.net MVC 1 website and I have a create/edit form that uses the default model binding to parse the form into a strongly typed complex object. The object I'm posting has a child collection of another complex type and the way I format my id's for the model binder is as follows: <div class="childContainer" > <!-- There's one of these for each property for each child collection item --> <%= Html.TextBox("ChildCollectionName[0].ChildPropertyName", /* blah blah */ ) %> <%= Html.TextBox("ChildCollectionName[0].OtherChildPropertyName", /* blah blah */ ) %> <!-- ... --> </div> This gets rendered as <div class="childContainer" > <input id="ChildCollectionName[0]_ChildPropertyName" ... /> <input id="ChildCollectionName[0]_OtherChildPropertyName" ... /> ... </div> <div class="childContainer" > <input id="ChildCollectionName[1]_ChildPropertyName" ... /> <input id="ChildCollectionName[1]_OtherChildPropertyName" ... /> ... </div> For each entry in the chlid collection. This collection is dynamically created in the form using jQuery, so entries can be added, removed etc. and whenever there's an operation on the collection I need to update the indexes so that it's bound correctly on the server side. What's the best way to replace all the html input id's when I'm updating the index within the child e.g. replace all [*] -- [N] where N is the correct index. using jQuery / JavaScript ? I have something coded now, but its buggy and I think there is a simpler solution. Also, if you have an easier way to identify the child collection I'll take any advice on that as well. Thanx!

• Copy constructor bug

  - by user168715

  I'm writing a simple nD-vector class, but am encountering a strange bug. I've stripped out the class to the bare minimum that still reproduces the bug: #include <iostream> using namespace std; template<unsigned int size> class nvector { public: nvector() {data_ = new double[size];} ~nvector() {delete[] data_;} template<unsigned int size2> nvector(const nvector<size2> &other) { data_ = new double[size]; int i=0; for(; i<size && i < size2; i++) data_[i] = other[i]; for(; i<size; i++) data_[i] = 0; } double &operator[](int i) {return data_[i];} const double&operator[](int i) const {return data_[i];} private: const nvector<size> &operator=(const nvector<size> &other); //Intentionally unimplemented for now double *data_; }; int main() { nvector<2> vector2d; vector2d[0] = 1; vector2d[1] = 2; nvector<3> vector3d(vector2d); for(int i=0; i<3; i++) cout << vector3d[i] << " "; cout << endl; //Prints 1 2 0 nvector<3> other3d(vector3d); for(int i=0; i<3; i++) cout << other3d[i] << " "; cout << endl; //Prints 1 2 0 } //Segfault??? On the surface this seems to work fine, and both tests print out the correct values. However, at the end of main the program crashes with a segfault, which I've traced to nvector's destructor. At first I thought the (incorrect) default assignment operator was somehow being called, which is why I added the (currently) unimplemented explicit assignment operator to rule this possibility out. So my copy constructor must be buggy, but I'm having one of those days where I'm staring at extremely simple code and just can't see it. Do you guys have any ideas?

• How Do I Setup the Notepad++ Run Command for Ruby?

  - by EstanislaoStan

  I'm trying to setup the Notepad++ IDE so that when I press F6 the Ruby script I'm editing will run. After searching the internet I've found that putting [cmd /K ruby "$(FULL_CURRENT_PATH)"] without the brackets into the run dialogue box that pops up when I press F5 will run basic scripts in the Command Prompt (I'm using Windows 7). However, if my code loads any external data such as .txt files, or as I've found with Gosu, loads any image files, Ruby complains that things do not exist which do in fact exist. I know my code and Ruby installation (Ruby 1.9.3) are fine because prior to now I've been using FreeRIDE, an older, somewhat buggy IDE that I've grown tired of, and my code runs fine when I press F5 using that IDE. Some examples of the complaints follow. My Text Adventure: C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Fold er/Ruby Scripts/Text Adventure/0.1.0/File Parser/DungeonContentFileParser.rb:8:i n `initialize': No such file or directory - Example Dungeon Creator File.txt (Er rno::ENOENT) from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Text Adventure/0.1.0/File Parser/DungeonContentFile Parser.rb:8:in `open' from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Text Adventure/0.1.0/File Parser/DungeonContentFile Parser.rb:8:in `encapsulate_method' from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Text Adventure/0.1.0/File Parser/DungeonContentFile Parser.rb:117:in `sort_room_data_external_method' from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Text Adventure/0.1.0/File Parser/DungeonContentFile Parser.rb:125:in `<main>' D:\Programming Stuff\Notepad++> My Gosu Program: C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Fold er/Ruby Scripts/Game Development/Circular Motion.rb:10:in `initialize': Could no t load image media/Space2.png using either GDI+ or FreeImage: Unknown error (Run timeError) from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Game Development/Circular Motion.rb:10:in `new' from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Game Development/Circular Motion.rb:10:in `initiali ze' from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Game Development/Circular Motion.rb:181:in `new' from C:/Users/Estanislao/Dropbox/Allway Sync/My Important Documents/Text Focused Folder/Ruby Scripts/Game Development/Circular Motion.rb:181:in `<main>' D:\Programming Stuff\Notepad++> If anyone could lend any help at all I'd really appreciate it.

• Can you call FB.login inside a callback from other FB methods (like FB.getLoginStatus) without triggering popup blockers?

  - by Erik Kallevig

  I'm trying to set up a pretty basic authentication logic flow with the FB JavaScript SDK to check a user's logged-in status and permissions before performing an action (and prompting the user to login with permissions if they are not)... User types a message into a textarea on my site to post to their Facebook feed and click's a 'post to facebook' button on my site. In response to the click, I check user's logged in status with FB.getLoginStatus In the callback to FB.getLoginStatus, if user is not logged in, prompt them to login (FB.login). In the callback to FB.login I then need to make sure they have the right permissions so I make a call to FB.api('/me/permissions') -- if they don't , I again prompt them to login (FB.login) The problem I'm running into is that anytime I try to call FB.login inside a callback to other FB methods, the browser seems to lose track of the origin of execution (the click) and thus will block the popup. I'm wondering if I'm missing some way to prompt the user to login after checking their status without the browser mistakenly thinking that it's not a user-initiated popup? I've currently fallen back to just calling FB.login() first regardless. The undesired side effect of this approach, however, is that if the user is already logged-in with permissions and I'm still calling FB.login, the auth popup will open and close immediately before continuing, which looks rather buggy despite being functional. It seems like checking a user's login status and permissions before doing something would be a common flow so I feel like I'm missing something. Here's some example code. <div onclick="onClickPostBtn()">Post to Facebook</div> <script> // Callback to click on Post button. function onClickPostBtn() { // Check if logged in, prompt to do so if not. FB.getLoginStatus(function(response) { if (response.status === 'connected') { checkPermissions(response.authResponse.accessToken); } else { FB.login(function(){}, {scope: 'publish_stream'}) } }); } // Logged in, check permissions. function checkPermissions(accessToken) { FB.api('/me/permissions', {'access_token': accessToken}, function(response){ // Logged in and authorized for this site. if (response.data && response.data.length) { // Parse response object to check for permission here... if (hasPermission) { // Logged in with permission, perform some action. } else { // Logged in without proper permission, request login with permissions. FB.login(function(){}, {scope: 'publish_stream'}) } // Logged in to FB but not authorized for this site. } else { FB.login(function(){}, {scope: 'publish_stream'}) } } ); } </script>

• C++ Regarding cin.ignore()

  - by user1578897

  i would hope someone can modify my code as its so buggy. sometime its work, sometime it dont.. so let me explain more.. Text file data is as below Line3D, [70, -120, -3], [-29, 1, 268] Line3D, [25, -69, -33], [-2, -41, 58] To read the above line.. i use the following char buffer[30]; cout << "Please enter filename: "; cin.ignore(); getline(cin,filename); readFile.open(filename.c_str()); //if successfully open if(readFile.is_open()) { //record counter set to 0 numberOfRecords = 0; while(readFile.good()) { //input stream get line by line readFile.getline(buffer,20,','); if(strstr(buffer,"Point3D")) { Point3D point3d_tmp; readFile>>point3d_tmp; // and so on... Then i did a overload on the ifstream for Line3d ifstream& operator>>(ifstream &input,Line3D &line3d) { int x1,y1,z1,x2,y2,z2; //get x1 input.ignore(2); input>>x1; //get y1 input.ignore(); input>>y1; //get z1 input.ignore(); input>>z1; //get x2 input.ignore(4); input>>x2; //get y2 input.ignore(); input>>y2; //get z2 input.ignore(); input>>z2; input.ignore(2); Point3D pt1(x1,y1,z1); Point3D pt2(x2,y2,z2); line3d.setPt1(pt1); line3d.setPt2(pt2); line3d.setLength(); } But the issue is the record work sometime and sometime it dont.. what i mean is if at this point //i add a cout cout << x1 << y1 << z1; cout << x2 << y2 << z2; //its works! Point3D pt1(x1,y1,z1); Point3D pt2(x2,y2,z2); line3d.setPt1(pt1); line3d.setPt2(pt2); line3d.setLength(); but if i take away the cout it dont work. how do i change my cin.ignore() so the data can be handle properly , consider number range is -999 to 999

• Windows 7, HTTPS WebDav: Asks for password twice and fails. Any workarounds?

  - by AutoDMC

  Howdy. I have a Dav server running with PHP SabreDav (code.google.com/p/sabredav/wiki/Windows) on Cherokee at an HTTPS secured URL. It's set to use https, and uses Digest Authentication. I can log in with multiple browsers and a few third party clients (BitKinex and Java AnyClient can connect and browse as well, caveats below). However, when attempting to log in with Windows 7 (surprise, surprise), it asks for my password twice, then tells me that my folder is invalid. I have verified that the server is using Digest authentication. I've verified multiple times that third party software can connect. I even went out and bought a GoDaddy SSL certificate so my SSL wouldn't be self signed anymore. I've applied the registry hacks here: support.microsoft.com/kb/943280 (Note that the article says the "fix" already exists for Windows 7, I just need magical registry hax to get it to work) I've applied the registry hacks here: support.microsoft.com/kb/941050 I've applied the registry hacks here: support.microsoft.com/kb/841215 (Supposedly allows Basic Auth, which shouldn't apply, but why not?) All to no avail; Windows continues to ask for my password twice, then state that "The folder you entered does not appear to be valid. Please choose another." Try the command line? Sure: I've attempted to access with NET USE "https://dav.example.com/" password /USER:me (System error 59) I've attempted to access with NET USE "https://dav.example.com/" (System error 1790) I've attempted to access with NET USE "https://dav.example.com/subdir/" password /USER:me (System error 59) I've attempted to access with NET USE "https://dav.example.com/subdir/" (System error 1790) For good luck: ping dav.example.com ... works. And again, web browsers can access the share just fine, so can third party tools. Best I can tell at this point is "HAHA, NO WEBDAV FOR YOU ON WINDOWS 7" which would be fine except everyone who will be using this application... uses Windows 7. And most are not as persistent or pugnacious as I am. I feel like I've burned through every random suggestion I've found anywhere in the first 10 pages of Google on every search term I can think of. Any ideas? I need it to be Webdav, I need it to be over HTTPS, and I really do need a method to access it from Windows 7. EXTRA DETAIL: However, the "third party" programs I've tried have either been buggy, incomplete, or have silly ... "glitches." For example, BitKinex seems to fixate on any http error codes sent, so if there's a glitch reading a directory, BAM, that directory is always listed empty. Long directory listings also show up as blank, even though the transfer panel shows that directory listing is still taking place. In any case, BitKinex is useless for development purposes for the reasons above. And besides, I'm building this for people other than myself, people who will want to get this dav share working "the regular way."

• How to Reduce the Size of Your WinSXS Folder on Windows 7 or 8

  - by Chris Hoffman

  The WinSXS folder at C:\Windows\WinSXS is massive and continues to grow the longer you have Windows installed. This folder builds up unnecessary files over time, such as old versions of system components. This folder also contains files for uninstalled, disabled Windows components. Even if you don’t have a Windows component installed, it will be present in your WinSXS folder, taking up space. Why the WinSXS Folder Gets to Big The WinSXS folder contains all Windows system components. In fact, component files elsewhere in Windows are just links to files contained in the WinSXS folder. The WinSXS folder contains every operating system file. When Windows installs updates, it drops the new Windows component in the WinSXS folder and keeps the old component in the WinSXS folder. This means that every Windows Update you install increases the size of your WinSXS folder. This allows you to uninstall operating system updates from the Control Panel, which can be useful in the case of a buggy update — but it’s a feature that’s rarely used. Windows 7 dealt with this by including a feature that allows Windows to clean up old Windows update files after you install a new Windows service pack. The idea was that the system could be cleaned up regularly along with service packs. However, Windows 7 only saw one service pack — Service Pack 1 — released in 2010. Microsoft has no intention of launching another. This means that, for more than three years, Windows update uninstallation files have been building up on Windows 7 systems and couldn’t be easily removed. Clean Up Update Files To fix this problem, Microsoft recently backported a feature from Windows 8 to Windows 7. They did this without much fanfare — it was rolled out in a typical minor operating system update, the kind that don’t generally add new features. To clean up such update files, open the Disk Cleanup wizard (tap the Windows key, type “disk cleanup” into the Start menu, and press Enter). Click the Clean up System Files button, enable the Windows Update Cleanup option and click OK. If you’ve been using your Windows 7 system for a few years, you’ll likely be able to free several gigabytes of space. The next time you reboot after doing this, Windows will take a few minutes to clean up system files before you can log in and use your desktop. If you don’t see this feature in the Disk Cleanup window, you’re likely behind on your updates — install the latest updates from Windows Update. Windows 8 and 8.1 include built-in features that do this automatically. In fact, there’s a StartComponentCleanup scheduled task included with Windows that will automatically run in the background, cleaning up components 30 days after you’ve installed them. This 30-day period gives you time to uninstall an update if it causes problems. If you’d like to manually clean up updates, you can also use the Windows Update Cleanup option in the Disk Usage window, just as you can on Windows 7. (To open it, tap the Windows key, type “disk cleanup” to perform a search, and click the “Free up disk space by removing unnecessary files” shortcut that appears.) Windows 8.1 gives you more options, allowing you to forcibly remove all previous versions of uninstalled components, even ones that haven’t been around for more than 30 days. These commands must be run in an elevated Command Prompt — in other words, start the Command Prompt window as Administrator. For example, the following command will uninstall all previous versions of components without the scheduled task’s 30-day grace period: DISM.exe /online /Cleanup-Image /StartComponentCleanup The following command will remove files needed for uninstallation of service packs. You won’t be able to uninstall any currently installed service packs after running this command: DISM.exe /online /Cleanup-Image /SPSuperseded The following command will remove all old versions of every component. You won’t be able to uninstall any currently installed service packs or updates after this completes: DISM.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase Remove Features on Demand Modern versions of Windows allow you to enable or disable Windows features on demand. You’ll find a list of these features in the Windows Features window you can access from the Control Panel. Even features you don’t have installed — that is, the features you see unchecked in this window — are stored on your hard drive in your WinSXS folder. If you choose to install them, they’ll be made available from your WinSXS folder. This means you won’t have to download anything or provide Windows installation media to install these features. However, these features take up space. While this shouldn’t matter on typical computers, users with extremely low amounts of storage or Windows server administrators who want to slim their Windows installs down to the smallest possible set of system files may want to get these files off their hard drives. For this reason, Windows 8 added a new option that allows you to remove these uninstalled components from the WinSXS folder entirely, freeing up space. If you choose to install the removed components later, Windows will prompt you to download the component files from Microsoft. To do this, open a Command Prompt window as Administrator. Use the following command to see the features available to you: DISM.exe /Online /English /Get-Features /Format:Table You’ll see a table of feature names and their states. To remove a feature from your system, you’d use the following command, replacing NAME with the name of the feature you want to remove. You can get the feature name you need from the table above.

• Metrics - A little knowledge can be a dangerous thing (or 'Why you're not clever enough to interpret metrics data')

  - by Jason Crease

  At RedGate Software, I work on a .NET obfuscator  called SmartAssembly.  Various features of it use a database to store various things (exception reports, name-mappings, etc.) The user is given the option of using either a SQL-Server database (which requires them to have Microsoft SQL Server), or a Microsoft Access MDB file (which requires nothing). MDB is the default option, but power-users soon switch to using a SQL Server database because it offers better performance and data-sharing. In the fashionable spirit of optimization and metrics, an obvious product-management question is 'Which is the most popular? SQL Server or MDB?' We've collected data about this fact, using our 'Feature-Usage-Reporting' technology (available as part of SmartAssembly) and more recently our 'Application Metrics' technology: Parameter Number of users % of total users Number of sessions Number of usages SQL Server 28 19.0 8115 8115 MDB 114 77.6 1449 1449 (As a disclaimer, please note than SmartAssembly has far more than 132 users . This data is just a selection of one build) So, it would appear that SQL-Server is used by fewer users, but more often. Great. But here's why these numbers are useless to me: Only the original developers understand the data What does a single 'usage' of 'MDB' mean? Does this happen once per run? Once per option change? On clicking the 'Obfuscate Now' button? When running the command-line version or just from the UI version? Each question could skew the data 10-fold either way, and the answers only known by the developer that instrumented the application in the first place. In other words, only the original developer can interpret the data - product-managers cannot interpret the data unaided. Most of the data is from uninterested users About half of people who download and run a free-trial from the internet quit it almost immediately. Only a small fraction use it sufficiently to make informed choices. Since the MDB option is the default one, we don't know how many of those 114 were people CHOOSING to use the MDB, or how many were JUST HAPPENING to use this MDB default for their 20-second trial. This is a problem we see across all our metrics: Are people are using X because it's the default or are they using X because they want to use X? We need to segment the data further - asking what percentage of each percentage meet our criteria for an 'established user' or 'informed user'. You end up spending hours writing sophisticated and dubious SQL queries to segment the data further. Not fun. You can't find out why they used this feature Metrics can answer the when and what, but not the why. Why did people use feature X? If you're anything like me, you often click on random buttons in unfamiliar applications just to explore the feature-set. If we listened uncritically to metrics at RedGate, we would eliminate the most-important and more-complex features which people actually buy the software for, leaving just big buttons on the main page and the About-Box. "Ah, that's interesting!" rather than "Ah, that's actionable!" People do love data. Did you know you eat 1201 chickens in a lifetime? But just 4 cows? Interesting, but useless. Often metrics give you a nice number: '5.8% of users have 3 or more monitors' . But unless the statistic is both SUPRISING and ACTIONABLE, it's useless. Most metrics are collected, reviewed with lots of cooing. and then forgotten. Unless a piece-of-data could change things, it's useless collecting it. People get obsessed with significance levels The first things that lots of people do with this data is do a t-test to get a significance level ("Hey! We know with 99.64% confidence that people prefer SQL Server to MDBs!") Believe me: other causes of error/misinterpretation in your data are FAR more significant than your t-test could ever comprehend. Confirmation bias prevents objectivity If the data appears to match our instinct, we feel satisfied and move on. If it doesn't, we suspect the data and dig deeper, plummeting down a rabbit-hole of segmentation and filtering until we give-up and move-on. Data is only useful if it can change our preconceptions. Do you trust this dodgy data more than your own understanding, knowledge and intelligence?  I don't. There's always multiple plausible ways to interpret/action any data Let's say we segment the above data, and get this data: Post-trial users (i.e. those using a paid version after the 14-day free-trial is over): Parameter Number of users % of total users Number of sessions Number of usages SQL Server 13 9.0 1115 1115 MDB 5 4.2 449 449 Trial users: Parameter Number of users % of total users Number of sessions Number of usages SQL Server 15 10.0 7000 7000 MDB 114 77.6 1000 1000 How do you interpret this data? It's one of: Mostly SQL Server users buy our software. People who can't afford SQL Server tend to be unable to afford or unwilling to buy our software. Therefore, ditch MDB-support. Our MDB support is so poor and buggy that our massive MDB user-base doesn't buy it.  Therefore, spend loads of money improving it, and think about ditching SQL-Server support. People 'graduate' naturally from MDB to SQL Server as they use the software more. Things are fine the way they are. We're marketing the tool wrong. The large number of MDB users represent uninformed downloaders. Tell marketing to aggressively target SQL Server users. To choose an interpretation you need to segment again. And again. And again, and again. Opting-out is correlated with feature-usage Metrics tends to be opt-in. This skews the data even further. Between 5% and 30% of people choose to opt-in to metrics (often called 'customer improvement program' or something like that). Casual trial-users who are uninterested in your product or company are less likely to opt-in. This group is probably also likely to be MDB users. How much does this skew your data by? Who knows? It's not all doom and gloom. There are some things metrics can answer well. Environment facts. How many people have 3 monitors? Have Windows 7? Have .NET 4 installed? Have Japanese Windows? Minor optimizations.  Is the text-box big enough for average user-input? Performance data. How long does our app take to start? How many databases does the average user have on their server? As you can see, questions about who-the-user-is rather than what-the-user-does are easier to answer and action. Conclusion Use SmartAssembly. If not for the metrics (called 'Feature-Usage-Reporting'), then at least for the obfuscation/error-reporting. Data raises more questions than it answers. Questions about environment are the easiest to answer.

• Parallelism in .NET – Part 4, Imperative Data Parallelism: Aggregation

  - by Reed

  In the article on simple data parallelism, I described how to perform an operation on an entire collection of elements in parallel.  Often, this is not adequate, as the parallel operation is going to be performing some form of aggregation. Simple examples of this might include taking the sum of the results of processing a function on each element in the collection, or finding the minimum of the collection given some criteria.  This can be done using the techniques described in simple data parallelism, however, special care needs to be taken into account to synchronize the shared data appropriately.  The Task Parallel Library has tools to assist in this synchronization. The main issue with aggregation when parallelizing a routine is that you need to handle synchronization of data.  Since multiple threads will need to write to a shared portion of data.  Suppose, for example, that we wanted to parallelize a simple loop that looked for the minimum value within a dataset: double min = double.MaxValue; foreach(var item in collection) { double value = item.PerformComputation(); min = System.Math.Min(min, value); } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } This seems like a good candidate for parallelization, but there is a problem here.  If we just wrap this into a call to Parallel.ForEach, we’ll introduce a critical race condition, and get the wrong answer.  Let’s look at what happens here: // Buggy code! Do not use! double min = double.MaxValue; Parallel.ForEach(collection, item => { double value = item.PerformComputation(); min = System.Math.Min(min, value); }); This code has a fatal flaw: min will be checked, then set, by multiple threads simultaneously.  Two threads may perform the check at the same time, and set the wrong value for min.  Say we get a value of 1 in thread 1, and a value of 2 in thread 2, and these two elements are the first two to run.  If both hit the min check line at the same time, both will determine that min should change, to 1 and 2 respectively.  If element 1 happens to set the variable first, then element 2 sets the min variable, we’ll detect a min value of 2 instead of 1.  This can lead to wrong answers. Unfortunately, fixing this, with the Parallel.ForEach call we’re using, would require adding locking.  We would need to rewrite this like: // Safe, but slow double min = double.MaxValue; // Make a "lock" object object syncObject = new object(); Parallel.ForEach(collection, item => { double value = item.PerformComputation(); lock(syncObject) min = System.Math.Min(min, value); }); This will potentially add a huge amount of overhead to our calculation.  Since we can potentially block while waiting on the lock for every single iteration, we will most likely slow this down to where it is actually quite a bit slower than our serial implementation.  The problem is the lock statement – any time you use lock(object), you’re almost assuring reduced performance in a parallel situation.  This leads to two observations I’ll make: When parallelizing a routine, try to avoid locks. That being said: Always add any and all required synchronization to avoid race conditions. These two observations tend to be opposing forces – we often need to synchronize our algorithms, but we also want to avoid the synchronization when possible.  Looking at our routine, there is no way to directly avoid this lock, since each element is potentially being run on a separate thread, and this lock is necessary in order for our routine to function correctly every time. However, this isn’t the only way to design this routine to implement this algorithm.  Realize that, although our collection may have thousands or even millions of elements, we have a limited number of Processing Elements (PE).  Processing Element is the standard term for a hardware element which can process and execute instructions.  This typically is a core in your processor, but many modern systems have multiple hardware execution threads per core.  The Task Parallel Library will not execute the work for each item in the collection as a separate work item. Instead, when Parallel.ForEach executes, it will partition the collection into larger “chunks” which get processed on different threads via the ThreadPool.  This helps reduce the threading overhead, and help the overall speed.  In general, the Parallel class will only use one thread per PE in the system. Given the fact that there are typically fewer threads than work items, we can rethink our algorithm design.  We can parallelize our algorithm more effectively by approaching it differently.  Because the basic aggregation we are doing here (Min) is communitive, we do not need to perform this in a given order.  We knew this to be true already – otherwise, we wouldn’t have been able to parallelize this routine in the first place.  With this in mind, we can treat each thread’s work independently, allowing each thread to serially process many elements with no locking, then, after all the threads are complete, “merge” together the results. This can be accomplished via a different set of overloads in the Parallel class: Parallel.ForEach<TSource,TLocal>.  The idea behind these overloads is to allow each thread to begin by initializing some local state (TLocal).  The thread will then process an entire set of items in the source collection, providing that state to the delegate which processes an individual item.  Finally, at the end, a separate delegate is run which allows you to handle merging that local state into your final results. To rewriting our routine using Parallel.ForEach<TSource,TLocal>, we need to provide three delegates instead of one.  The most basic version of this function is declared as: public static ParallelLoopResult ForEach<TSource, TLocal>( IEnumerable<TSource> source, Func<TLocal> localInit, Func<TSource, ParallelLoopState, TLocal, TLocal> body, Action<TLocal> localFinally ) The first delegate (the localInit argument) is defined as Func<TLocal>.  This delegate initializes our local state.  It should return some object we can use to track the results of a single thread’s operations. The second delegate (the body argument) is where our main processing occurs, although now, instead of being an Action<T>, we actually provide a Func<TSource, ParallelLoopState, TLocal, TLocal> delegate.  This delegate will receive three arguments: our original element from the collection (TSource), a ParallelLoopState which we can use for early termination, and the instance of our local state we created (TLocal).  It should do whatever processing you wish to occur per element, then return the value of the local state after processing is completed. The third delegate (the localFinally argument) is defined as Action<TLocal>.  This delegate is passed our local state after it’s been processed by all of the elements this thread will handle.  This is where you can merge your final results together.  This may require synchronization, but now, instead of synchronizing once per element (potentially millions of times), you’ll only have to synchronize once per thread, which is an ideal situation. Now that I’ve explained how this works, lets look at the code: // Safe, and fast! double min = double.MaxValue; // Make a "lock" object object syncObject = new object(); Parallel.ForEach( collection, // First, we provide a local state initialization delegate. () => double.MaxValue, // Next, we supply the body, which takes the original item, loop state, // and local state, and returns a new local state (item, loopState, localState) => { double value = item.PerformComputation(); return System.Math.Min(localState, value); }, // Finally, we provide an Action<TLocal>, to "merge" results together localState => { // This requires locking, but it's only once per used thread lock(syncObj) min = System.Math.Min(min, localState); } ); Although this is a bit more complicated than the previous version, it is now both thread-safe, and has minimal locking.  This same approach can be used by Parallel.For, although now, it’s Parallel.For<TLocal>.  When working with Parallel.For<TLocal>, you use the same triplet of delegates, with the same purpose and results. Also, many times, you can completely avoid locking by using a method of the Interlocked class to perform the final aggregation in an atomic operation.  The MSDN example demonstrating this same technique using Parallel.For uses the Interlocked class instead of a lock, since they are doing a sum operation on a long variable, which is possible via Interlocked.Add. By taking advantage of local state, we can use the Parallel class methods to parallelize algorithms such as aggregation, which, at first, may seem like poor candidates for parallelization.  Doing so requires careful consideration, and often requires a slight redesign of the algorithm, but the performance gains can be significant if handled in a way to avoid excessive synchronization.

• Write-error on swap-device, Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK

  - by Jan

  My root server at 1&1 was unresponsive on HTTP and SSH, so I logged into the serial console . It flooded my connection with endless error messages like quoted below. I initiated a reboot and now everything seems to work properly. After googling, I installed smartctl and ran a short self test, which told me the device was healthy. Is this likely a disk failure soon to happen or could it be just some program going wild? I assume, the swap device could also grow full when huge amounts of memory get consumed by a buggy program? How can I find out for sure? The sever was already unresponsive a week ago when I just restarted it without proper investigation. The server is running on CentOS.

• T-SQL Tuesday #53-Matt's Making Me Do This!

  - by Most Valuable Yak (Rob Volk)

  Hello everyone! It's that time again, time for T-SQL Tuesday, the wonderful blog series started by Adam Machanic (b|t). This month we are hosted by Matt Velic (b|t) who asks the question, "Why So Serious?", in celebration of April Fool's Day. He asks the contributors for their dirty tricks. And for some reason that escapes me, he and Jeff Verheul (b|t) seem to think I might be able to write about those. Shocked, I am! Nah, not really. They're absolutely right, this one is gonna be fun! I took some inspiration from Matt's suggestions, namely Resource Governor and Login Triggers.  I've done some interesting login trigger stuff for a presentation, but nothing yet with Resource Governor. Best way to learn it! One of my oldest pet peeves is abuse of the sa login. Don't get me wrong, I use it too, but typically only as SQL Agent job owner. It's been a while since I've been stuck with it, but back when I started using SQL Server, EVERY application needed sa to function. It was hard-coded and couldn't be changed. (welllllll, that is if you didn't use a hex editor on the EXE file, but who would do such a thing?) My standard warning applies: don't run anything on this page in production. In fact, back up whatever server you're testing this on, including the master database. Snapshotting a VM is a good idea. Also make sure you have other sysadmin level logins on that server. So here's a standard template for a logon trigger to address those pesky sa users: CREATE TRIGGER SA_LOGIN_PRIORITY ON ALL SERVER WITH ENCRYPTION, EXECUTE AS N'sa' AFTER LOGON AS IF ORIGINAL_LOGIN()<>N'sa' OR APP_NAME() LIKE N'SQL Agent%' RETURN; -- interesting stuff goes here GO   What can you do for "interesting stuff"? Books Online limits itself to merely rolling back the logon, which will throw an error (and alert the person that the logon trigger fired).  That's a good use for logon triggers, but really not tricky enough for this blog.  Some of my suggestions are below: WAITFOR DELAY '23:59:59';   Or: EXEC sp_MSforeach_db 'EXEC sp_detach_db ''?'';'   Or: EXEC msdb.dbo.sp_add_job @job_name=N'`', @enabled=1, @start_step_id=1, @notify_level_eventlog=0, @delete_level=3; EXEC msdb.dbo.sp_add_jobserver @job_name=N'`', @server_name=@@SERVERNAME; EXEC msdb.dbo.sp_add_jobstep @job_name=N'`', @step_id=1, @step_name=N'`', @command=N'SHUTDOWN;'; EXEC msdb.dbo.sp_start_job @job_name=N'`';   Really, I don't want to spoil your own exploration, try it yourself!  The thing I really like about these is it lets me promote the idea that "sa is SLOW, sa is BUGGY, don't use sa!".  Before we get into Resource Governor, make sure to drop or disable that logon trigger. They don't work well in combination. (Had to redo all the following code when SSMS locked up) Resource Governor is a feature that lets you control how many resources a single session can consume. The main goal is to limit the damage from a runaway query. But we're not here to read about its main goal or normal usage! I'm trying to make people stop using sa BECAUSE IT'S SLOW! Here's how RG can do that: USE master; GO CREATE FUNCTION dbo.SA_LOGIN_PRIORITY() RETURNS sysname WITH SCHEMABINDING, ENCRYPTION AS BEGIN RETURN CASE WHEN ORIGINAL_LOGIN()=N'sa' AND APP_NAME() NOT LIKE N'SQL Agent%' THEN N'SA_LOGIN_PRIORITY' ELSE N'default' END END GO CREATE RESOURCE POOL SA_LOGIN_PRIORITY WITH ( MIN_CPU_PERCENT = 0 ,MAX_CPU_PERCENT = 1 ,CAP_CPU_PERCENT = 1 ,AFFINITY SCHEDULER = (0) ,MIN_MEMORY_PERCENT = 0 ,MAX_MEMORY_PERCENT = 1 -- ,MIN_IOPS_PER_VOLUME = 1 ,MAX_IOPS_PER_VOLUME = 1 -- uncomment for SQL Server 2014 ); CREATE WORKLOAD GROUP SA_LOGIN_PRIORITY WITH ( IMPORTANCE = LOW ,REQUEST_MAX_MEMORY_GRANT_PERCENT = 1 ,REQUEST_MAX_CPU_TIME_SEC = 1 ,REQUEST_MEMORY_GRANT_TIMEOUT_SEC = 1 ,MAX_DOP = 1 ,GROUP_MAX_REQUESTS = 1 ) USING SA_LOGIN_PRIORITY; ALTER RESOURCE GOVERNOR WITH (CLASSIFIER_FUNCTION=dbo.SA_LOGIN_PRIORITY); ALTER RESOURCE GOVERNOR RECONFIGURE;   From top to bottom: Create a classifier function to determine which pool the session should go to. More info on classifier functions. Create the pool and provide a generous helping of resources for the sa login. Create the workload group and further prioritize those resources for the sa login. Apply the classifier function and reconfigure RG to use it. I have to say this one is a bit sneakier than the logon trigger, least of all you don't get any error messages.  I heartily recommend testing it in Management Studio, and click around the UI a lot, there's some fun behavior there. And DEFINITELY try it on SQL 2014 with the IO settings included!  You'll notice I made allowances for SQL Agent jobs owned by sa, they'll go into the default workload group.  You can add your own overrides to the classifier function if needed. Some interesting ideas I didn't have time for but expect you to get to before me: Set up different pools/workgroups with different settings and randomize which one the classifier chooses Do the same but base it on time of day (Books Online example covers this)... Or, which workstation it connects from. This can be modified for certain special people in your office who either don't listen, or are attracted (and attractive) to you. And if things go wrong you can always use the following from another sysadmin or Dedicated Admin connection: ALTER RESOURCE GOVERNOR DISABLE;   That will let you go in and either fix (or drop) the pools, workgroups and classifier function. So now that you know these types of things are possible, and if you are tired of your team using sa when they shouldn't, I expect you'll enjoy playing with these quite a bit! Unfortunately, the aforementioned Dedicated Admin Connection kinda poops on the party here.  Books Online for both topics will tell you that the DAC will not fire either feature. So if you have a crafty user who does their research, they can still sneak in with sa and do their bidding without being hampered. Of course, you can still detect their login via various methods, like a server trace, SQL Server Audit, extended events, and enabling "Audit Successful Logins" on the server.  These all have their downsides: traces take resources, extended events and SQL Audit can't fire off actions, and enabling successful logins will bloat your error log very quickly.  SQL Audit is also limited unless you have Enterprise Edition, and Resource Governor is Enterprise-only.  And WORST OF ALL, these features are all available and visible through the SSMS UI, so even a doofus developer or manager could find them. Fortunately there are Event Notifications! Event notifications are becoming one of my favorite features of SQL Server (keep an eye out for more blogs from me about them). They are practically unknown and heinously underutilized.  They are also a great gateway drug to using Service Broker, another great but underutilized feature. Hopefully this will get you to start using them, or at least your enemies in the office will once they read this, and then you'll have to learn them in order to fix things. So here's the setup: USE msdb; GO CREATE PROCEDURE dbo.SA_LOGIN_PRIORITY_act WITH ENCRYPTION AS DECLARE @x XML, @message nvarchar(max); RECEIVE @x=CAST(message_body AS XML) FROM SA_LOGIN_PRIORITY_q; IF @x.value('(//LoginName)[1]','sysname')=N'sa' AND @x.value('(//ApplicationName)[1]','sysname') NOT LIKE N'SQL Agent%' BEGIN -- interesting activation procedure stuff goes here END GO CREATE QUEUE SA_LOGIN_PRIORITY_q WITH STATUS=ON, RETENTION=OFF, ACTIVATION (PROCEDURE_NAME=dbo.SA_LOGIN_PRIORITY_act, MAX_QUEUE_READERS=1, EXECUTE AS OWNER); CREATE SERVICE SA_LOGIN_PRIORITY_s ON QUEUE SA_LOGIN_PRIORITY_q([http://schemas.microsoft.com/SQL/Notifications/PostEventNotification]); CREATE EVENT NOTIFICATION SA_LOGIN_PRIORITY_en ON SERVER WITH FAN_IN FOR AUDIT_LOGIN TO SERVICE N'SA_LOGIN_PRIORITY_s', N'current database' GO   From top to bottom: Create activation procedure for event notification queue. Create queue to accept messages from event notification, and activate the procedure to process those messages when received. Create service to send messages to that queue. Create event notification on AUDIT_LOGIN events that fire the service. I placed this in msdb as it is an available system database and already has Service Broker enabled by default. You should change this to another database if you can guarantee it won't get dropped. So what to put in place for "interesting activation procedure code"?  Hmmm, so far I haven't addressed Matt's suggestion of writing a lengthy script to send an annoying message: SET @[email protected]('(//HostName)[1]','sysname') + N' tried to log in to server ' + @x.value('(//ServerName)[1]','sysname') + N' as SA at ' + @x.value('(//StartTime)[1]','sysname') + N' using the ' + @x.value('(//ApplicationName)[1]','sysname') + N' program. That''s why you''re getting this message and the attached pornography which' + N' is bloating your inbox and violating company policy, among other things. If you know' + N' this person you can go to their desk and hit them, or use the following SQL to end their session: KILL ' + @x.value('(//SPID)[1]','sysname') + N'; Hopefully they''re in the middle of a huge query that they need to finish right away.' EXEC msdb.dbo.sp_send_dbmail @recipients=N'[email protected]', @subject=N'SA Login Alert', @query_result_width=32767, @body=@message, @query=N'EXEC sp_readerrorlog;', @attach_query_result_as_file=1, @query_attachment_filename=N'UtterlyGrossPorn_SeriouslyDontOpenIt.jpg' I'm not sure I'd call that a lengthy script, but the attachment should get pretty big, and I'm sure the email admins will love storing multiple copies of it.  The nice thing is that this also fires on Dedicated Admin connections! You can even identify DAC connections from the event data returned, I leave that as an exercise for you. You can use that info to change the action taken by the activation procedure, and since it's a stored procedure, it can pretty much do anything! Except KILL the SPID, or SHUTDOWN the server directly.  I'm still working on those.

• 500 Internal Server Error with PHP application

• The Return Of __FILE__ And __LINE__ In .NET 4.5

  - by Alois Kraus

  Good things are hard to kill. One of the most useful predefined compiler macros in C/C++ were __FILE__ and __LINE__ which do expand to the compilation units file name and line number where this value is encountered by the compiler. After 4.5 versions of .NET we are on par with C/C++ again. It is of course not a simple compiler expandable macro it is an attribute but it does serve exactly the same purpose. Now we do get CallerLineNumberAttribute  == __LINE__ CallerFilePathAttribute        == __FILE__ CallerMemberNameAttribute  == __FUNCTION__ (MSVC Extension)   The most important one is CallerMemberNameAttribute which is very useful to implement the INotifyPropertyChanged interface without the need to hard code the name of the property anymore. Now you can simply decorate your change method with the new CallerMemberName attribute and you get the property name as string directly inserted by the C# compiler at compile time.   public string UserName { get { return _userName; } set { _userName=value; RaisePropertyChanged(); // no more RaisePropertyChanged(“UserName”)! } } protected void RaisePropertyChanged([CallerMemberName] string member = "") { var copy = PropertyChanged; if(copy != null) { copy(new PropertyChangedEventArgs(this, member)); } } Nice and handy. This was obviously the prime reason to implement this feature in the C# 5.0 compiler. You can repurpose this feature for tracing to get your hands on the method name of your caller along other stuff very fast now. All infos are added during compile time which is much faster than other approaches like walking the stack. The example on MSDN shows the usage of this attribute with an example public static void TraceMessage(string message, [CallerMemberName] string memberName = "", [CallerFilePath] string sourceFilePath = "", [CallerLineNumber] int sourceLineNumber = 0) { Console.WriteLine("Hi {0} {1} {2}({3})", message, memberName, sourceFilePath, sourceLineNumber); }   When I do think of tracing I do usually want to have a API which allows me to Trace method enter and leave Trace messages with a severity like Info, Warning, Error When I do print a trace message it is very useful to print out method and type name as well. So your API must either be able to pass the method and type name as strings or extract it automatically via walking back one Stackframe and fetch the infos from there. The first glaring deficiency is that there is no CallerTypeAttribute yet because the C# compiler team was not satisfied with its performance.   A usable Trace Api might therefore look like   enum TraceTypes { None = 0, EnterLeave = 1 << 0, Info = 1 << 1, Warn = 1 << 2, Error = 1 << 3 } class Tracer : IDisposable { string Type; string Method; public Tracer(string type, string method) { Type = type; Method = method; if (IsEnabled(TraceTypes.EnterLeave,Type, Method)) { } } private bool IsEnabled(TraceTypes traceTypes, string Type, string Method) { // Do checking here if tracing is enabled return false; } public void Info(string fmt, params object[] args) { } public void Warn(string fmt, params object[] args) { } public void Error(string fmt, params object[] args) { } public static void Info(string type, string method, string fmt, params object[] args) { } public static void Warn(string type, string method, string fmt, params object[] args) { } public static void Error(string type, string method, string fmt, params object[] args) { } public void Dispose() { // trace method leave } } This minimal trace API is very fast but hard to maintain since you need to pass in the type and method name as hard coded strings which can change from time to time. But now we have at least CallerMemberName to rid of the explicit method parameter right? Not really. Since any acceptable usable trace Api should have a method signature like Tracexxx(… string fmt, params [] object args) we not able to add additional optional parameters after the args array. If we would put it before the format string we would need to make it optional as well which would mean the compiler would need to figure out what our trace message and arguments are (not likely) or we would need to specify everything explicitly just like before . There are ways around this by providing a myriad of overloads which in the end are routed to the very same method but that is ugly. I am not sure if nobody inside MS agrees that the above API is reasonable to have or (more likely) that the whole talk about you can use this feature for diagnostic purposes was not a core feature at all but a simple byproduct of making the life of INotifyPropertyChanged implementers easier. A way around this would be to allow for variable argument arrays after the params keyword another set of optional arguments which are always filled by the compiler but I do not know if this is an easy one. The thing I am missing much more is the not provided CallerType attribute. But not in the way you would think of. In the API above I did add some filtering based on method and type to stay as fast as possible for types where tracing is not enabled at all. It should be no more expensive than an additional method call and a bool variable check if tracing for this type is enabled at all. The data is tightly bound to the calling type and method and should therefore become part of the static type instance. Since extending the CLR type system for tracing is not something I do expect to happen I have come up with an alternative approach which allows me basically to attach run time data to any existing type object in super fast way. The key to success is the usage of generics.   class Tracer<T> : IDisposable { string Method; public Tracer(string method) { if (TraceData<T>.Instance.Enabled.HasFlag(TraceTypes.EnterLeave)) { } } public void Dispose() { if (TraceData<T>.Instance.Enabled.HasFlag(TraceTypes.EnterLeave)) { } } public static void Info(string fmt, params object[] args) { } /// <summary> /// Every type gets its own instance with a fresh set of variables to describe the /// current filter status. /// </summary> /// <typeparam name="T"></typeparam> internal class TraceData<UsingType> { internal static TraceData<UsingType> Instance = new TraceData<UsingType>(); public bool IsInitialized = false; // flag if we need to reinit the trace data in case of reconfigured trace settings at runtime public TraceTypes Enabled = TraceTypes.None; // Enabled trace levels for this type } } We do not need to pass the type as string or Type object to the trace Api. Instead we define a generic Api that accepts the using type as generic parameter. Then we can create a TraceData static instance which is due to the nature of generics a fresh instance for every new type parameter. My tests on my home machine have shown that this approach is as fast as a simple bool flag check. If you have an application with many types using tracing you do not want to bring the app down by simply enabling tracing for one special rarely used type. The trace filter performance for the types which are not enabled must be therefore the fasted code path. This approach has the nice side effect that if you store the TraceData instances in one global list you can reconfigure tracing at runtime safely by simply setting the IsInitialized flag to false. A similar effect can be achieved with a global static Dictionary<Type,TraceData> object but big hash tables have random memory access semantics which is bad for cache locality and you always need to pay for the lookup which involves hash code generation, equality check and an indexed array access. The generic version is wicked fast and allows you to add more features to your tracing Api with minimal perf overhead. But it is cumbersome to write the generic type argument always explicitly and worse if you do refactor code and move parts of it to other classes it might be that you cannot configure tracing correctly. I would like therefore to decorate my type with an attribute [CallerType] class Tracer<T> : IDisposable to tell the compiler to fill in the generic type argument automatically. class Program { static void Main(string[] args) { using (var t = new Tracer()) // equivalent to new Tracer<Program>() { That would be really useful and super fast since you do not need to pass any type object around but you do have full type infos at hand. This change would be breaking if another non generic type exists in the same namespace where now the generic counterpart would be preferred. But this is an acceptable risk in my opinion since you can today already get conflicts if two generic types of the same name are defined in different namespaces. This would be only a variation of this issue. When you do think about this further you can add more features like to trace the exception in your Dispose method if the method is left with an exception with that little trick I did write some time ago. You can think of tracing as a super fast and configurable switch to write data to an output destination or to execute alternative actions. With such an infrastructure you can e.g. Reconfigure tracing at run time. Take a memory dump when a specific method is left with a specific exception. Throw an exception when a specific trace statement is hit (useful for testing error conditions). Execute a passed delegate which e.g. dumps additional state when enabled. Write data to an in memory ring buffer and dump it when specific events do occur (e.g. method is left with an exception, triggered from outside). Write data to an output device. …. This stuff is really useful to have when your code is in production on a mission critical server and you need to find the root cause of sporadic crashes of your application. It could be a buggy graphics card driver which throws access violations into your application (ok with .NET 4 not anymore except if you enable a compatibility flag) where you would like to have a minidump or you have reached after two weeks of operation a state where you need a full memory dump at a specific point in time in the middle of an transaction. At my older machine I do get with this super fast approach 50 million traces/s when tracing is disabled. When I do know that tracing is enabled for this type I can walk the stack by using StackFrameHelper.GetStackFramesInternal to check further if a specific action or output device is configured for this method which is about 2-3 times faster than the regular StackTrace class. Even with one String.Format I am down to 3 million traces/s so performance is not so important anymore since I do want to do something now. The CallerMemberName feature of the C# 5 compiler is nice but I would have preferred to get direct access to the MethodHandle and not to the stringified version of it. But I really would like to see a CallerType attribute implemented to fill in the generic type argument of the call site to augment the static CLR type data with run time data.

  Hi folks, I can't get scipy to function in 32 bit mode when compiled as a i386/x86_64 universal binary, and executed on my 64 bit 10.6.2 MacPro1,1. My python setup With the help of this answer, I built a 32/64 bit intel universal binary of python 2.6.4 with the intention of using the arch command to select between the architectures. (I managed to make some universal binaries of a few libraries I wanted using lipo.) That all works. I then installed scipy according to the instructions on hyperjeff's article, only with more up-to-date numpy (1.4.0) and skipping the bit about moving numpy aside briefly during the installation of scipy. Now, everything except scipy seems to be working as far as I can tell, and I can indeed select between 32 and 64 bit mode using arch -i386 python and arch -x86_64 python. The error Scipy complains in 32 bit mode: $ arch -x86_64 python -c "import scipy.interpolate; print 'success'" success $ arch -i386 python -c "import scipy.interpolate; print 'success'" Traceback (most recent call last): File "<string>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/interpolate/__init__.py", line 7, in <module> from interpolate import * File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/interpolate/interpolate.py", line 13, in <module> import scipy.special as spec File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/__init__.py", line 8, in <module> from basic import * File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/basic.py", line 8, in <module> from _cephes import * ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so, 2): Symbol not found: _aswfa_ Referenced from: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so Expected in: flat namespace in /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so Attempt at tracking down the problem It looks like scipy.interpolate imports something called _cephes, which looks for a symbol called _aswfa_ but can't find it in 32 bit mode. Browsing through scipy's source, I find an ASWFA subroutine in specfun.f. The only scipy product file with a similar name is specfun.so, but both that and _cephes.so appear to be universal binaries: $ cd /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/ $ file _cephes.so specfun.so _cephes.so: Mach-O universal binary with 2 architectures _cephes.so (for architecture i386): Mach-O bundle i386 _cephes.so (for architecture x86_64): Mach-O 64-bit bundle x86_64 specfun.so: Mach-O universal binary with 2 architectures specfun.so (for architecture i386): Mach-O bundle i386 specfun.so (for architecture x86_64): Mach-O 64-bit bundle x86_64 Ho hum. I'm stuck. Things I may try but haven't figured out how yet include compiling specfun.so myself manually, somehow. I would imagine that scipy isn't broken for all 32 bit machines, so I guess something is wrong with the way I've installed it, but I can't figure out what. I don't really expect a full answer given my fairly unique (?) setup, but if anyone has any clues that might point me in the right direction, they'd be greatly appreciated. (edit) More details to address questions: I'm using gfortran (GNU Fortran from GCC 4.2.1 Apple Inc. build 5646). Python 2.6.4 was installed more-or-less like so: cd /tmp curl -O http://www.python.org/ftp/python/2.6.4/Python-2.6.4.tar.bz2 tar xf Python-2.6.4.tar.bz2 cd Python-2.6.4 # Now replace buggy pythonw.c file with one that supports the "arch" command: curl http://bugs.python.org/file14949/pythonw.c | sed s/2.7/2.6/ > Mac/Tools/pythonw.c ./configure --enable-framework=/Library/Frameworks --enable-universalsdk=/ --with-universal-archs=intel make -j4 sudo make frameworkinstall Scipy 0.7.1 was installed pretty much as described as here, but it boils down to a simple sudo python setup.py install. It would indeed appear that the symbol is undefined in the i386 architecture if you look at the _cephes library with nm, as suggested by David Cournapeau: $ nm -arch x86_64 /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so | grep _aswfa_ 00000000000d4950 T _aswfa_ 000000000011e4b0 d _oblate_aswfa_data 000000000011e510 d _oblate_aswfa_nocv_data (snip) $ nm -arch i386 /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/scipy/special/_cephes.so | grep _aswfa_ U _aswfa_ 0002e96c d _oblate_aswfa_data 0002e99c d _oblate_aswfa_nocv_data (snip) however, I can't yet explain its absence.

• How to cope with developing against a poor 3rd party API/application?

  - by wsanville

  I'm a web developer, and my organization has recently started to use a proprietary ASP.NET CMS for our web sites. I was excited to get started using the CMS, thinking it would bring a lot of value to our end users and be fun to work with, since my skills are a good match for the types of projects we're using it for. That was about a year ago. Since then, we've ran into all kinds of issues, from blatant bugs in the product, to nasty edge cases in the APIs, to extremely poor documentation for developers. On about a weekly basis, we are forced to pursue workarounds and rewrite some of the out of the box functionality, and even find some of the basic features unusable. In many cases, since this is a closed source application (and obfuscated of course), there's nothing we can do as developers to solve these issues. So my question is, how does one attempt to develop a good application in such a scenario? The application mostly works when using the the exact out of the box behavior, or using one of the company's starter sites. However, my attempts to use the underlying APIs to implement slightly different, yet reasonable behavior has proved to be extremely time consuming (not to mention just as buggy), given the lack of good information about the APIs. I've given this a lot of thought, and my conflicting viewpoints are the following: Strongly advise against any customization to the CMS, as development time will rise exponentially, or even have an extremely high chance of failing. While this is accurate, I do not want to give the impression that I am not willing to code my own solutions to problems and take the initiative to implement something difficult or complex. I don't want to be perceived as someone who is not motivated, lazy, or not knowledgeable to do anything complex, because this is simply not the case. I love coding my own solutions, trying new/difficult things, I just dislike the vendor app we're using. Continue on the path I'm on now, which is hacking my way past all issues I encounter and try my best to deliver an application that meets the needs and specs exactly. My goals are to make it as seamless and easy to use as possible to the end user, even when integrating the CMS with our other applications internally. The problem I'm finding with this approach is it is very time consuming. I open support cases with the vendor on a regular basis to solve issues and to gain knowledge of their APIs, but this is extremely time consuming, and in some cases it leads to dead ends. I post on the vendors forums on a regular basis but have become frustrated as most of my posts get 0 replies. So, what would you, a reasonable developer, do in this case? How can I make the best of the situation? And just for fun, here are some of the code smells and anti-patterns I've dealt with using the product (aside from their own code blatantly failing): Use of StringBuilder to concatenate a giant string that is hard coded and does not change. They use it to concatenate their Javascript and write it out into the body tags of their pages. Methods that accept object or Microsoft.VisualBasic.Collection as the parameters. In the case of the VB Collection, the data is not a list of any kind, it's used instead of making a class. Methods that return a Hashtable of VB Collections Method names of the form MethodName_v45, MethodName_v20, etc... Multiple classes with the same name in different namespaces with different functionality/behavior. Intellisense that reads "Note: this parameter is non functional" Complete lack of coding standards, API is filled with magic numbers and magic strings. Properties with a getter of type object that accepts totally different things, like enum or strings, and throw exceptions at runtime when you pass in something not supported. And much, much, more...

• Flash Mouse.hide() cmd+tab(alt+tab) bring the mouse back

  - by DickieBoy

  Having a bit of trouble with Mouse.show() and losing focus of the swf This isn't my demo: but its showing the same bug http://www.foundation-flash.com/tutorials/as3customcursors/ What i do to recreate it is: mouse over the swf, hit cmd+tab to highlight another window, result is that the mouse is not brought back and is still invisible, (to get it back go to the window bar at the top of the screen and click something). I have an area in which movement is detected and an image Things I have tried package { import flash.display.Sprite; import flash.display.MovieClip; import com.greensock.*; import flash.events.*; import flash.utils.Timer; import flash.events.TimerEvent; import flash.utils.*; import flash.ui.Mouse; public class mousey_movey extends MovieClip { public var middle_of_the_flash; //pixels per second public var speeds = [0,1,3,5,10]; public var speed; public var percentage_the_mouse_is_across_the_screen; public var mouse_over_scrollable_area:Boolean; public var image_move_interval; public function mousey_movey() { middle_of_the_flash = stage.stageWidth/2; hot_area_for_movement.addEventListener(MouseEvent.MOUSE_OVER, mouseEnter); hot_area_for_movement.addEventListener(MouseEvent.MOUSE_OUT, mouseLeave); hot_area_for_movement.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove); stage.addEventListener(Event.MOUSE_LEAVE, show_mouse); stage.addEventListener(MouseEvent.MOUSE_OUT, show_mouse); stage.addEventListener(Event.DEACTIVATE,show_mouse); hot_area_for_movement.alpha=0; hot_area_for_movement.x=0; hot_area_for_movement.y=34; } public function show_mouse(e) { trace(e.type) trace('show_mouse') Mouse.show(); } public function onActivate(e) { trace('activate'); Mouse.show(); } public function onDeactivate(e) { trace('deactivate'); } public function get_speed(percantage_from_middle):int { if(percantage_from_middle > 80) { return speeds[4] } else { if(percantage_from_middle > 60) { return speeds[3] } else { if(percantage_from_middle > 40) { return speeds[2] } else { if(percantage_from_middle > 20) { return speeds[1] } else { return 0; } } } } } public function mouseLeave(e:Event):void{ Mouse.show(); clearInterval(image_move_interval); } public function mouseEnter(e:Event):void{ Mouse.hide(); image_move_interval = setInterval(moveImage,1); } public function mouseMove(e:Event):void { percentage_the_mouse_is_across_the_screen = Math.round(((middle_of_the_flash-stage.mouseX)/middle_of_the_flash)*100); speed = get_speed(Math.abs(percentage_the_mouse_is_across_the_screen)); airplane_icon.x = stage.mouseX; airplane_icon.y = stage.mouseY; } public function stageMouseMove(e:Event):void{ Mouse.show(); } public function moveImage():void { if(percentage_the_mouse_is_across_the_screen > 0) { moving_image.x+=speed; airplane_icon.scaleX = -1; } else { moving_image.x-=speed; airplane_icon.scaleX = 1; } } } } Nothing too fancy, im just scrolling an image left of right at a speed which is generated by how far you are from the middle of the stage, and making an airplane moveclip follow the mouse. The events: stage.addEventListener(Event.MOUSE_LEAVE, show_mouse); stage.addEventListener(MouseEvent.MOUSE_OUT, show_mouse); stage.addEventListener(Event.DEACTIVATE,show_mouse); All fire and work correctly when in the browser, seem a little buggy when running a test through flash, was expecting this as ive experienced it before. The deactivate call even runs when testing and cmd+tabbing but shows no mouse. Any help on the matter is appreciated Thanks, Dickie

• Basic C question, concerning memory allocation and value assignment

  - by VHristov

  Hi there, I have recently started working on my master thesis in C that I haven't used in quite a long time. Being used to Java, I'm now facing all kinds of problems all the time. I hope someone can help me with the following one, since I've been struggling with it for the past two days. So I have a really basic model of a database: tables, tuples, attributes and I'm trying to load some data into this structure. Following are the definitions: typedef struct attribute { int type; char * name; void * value; } attribute; typedef struct tuple { int tuple_id; int attribute_count; attribute * attributes; } tuple; typedef struct table { char * name; int row_count; tuple * tuples; } table; Data is coming from a file with inserts (generated for the Wisconsin benchmark), which I'm parsing. I have only integer or string values. A sample row would look like: insert into table values (9205, 541, 1, 1, 5, 5, 5, 5, 0, 1, 9205, 10, 11, 'HHHHHHH', 'HHHHHHH', 'HHHHHHH'); I've "managed" to load and parse the data and also to assign it. However, the assignment bit is buggy, since all values point to the same memory location, i.e. all rows look identical after I've loaded the data. Here is what I do: char value[10]; // assuming no value is longer than 10 chars int i, j, k; table * data = (table*) malloc(sizeof(data)); data->name = "table"; data->row_count = number_of_lines; data->tuples = (tuple*) malloc(number_of_lines*sizeof(tuple)); tuple* current_tuple; for(i=0; i<number_of_lines; i++) { current_tuple = &data->tuples[i]; current_tuple->tuple_id = i; current_tuple->attribute_count = 16; // static in our system current_tuple->attributes = (attribute*) malloc(16*sizeof(attribute)); for(k = 0; k < 16; k++) { current_tuple->attributes[k].name = attribute_names[k]; // for int values: current_tuple->attributes[k].type = DB_ATT_TYPE_INT; // write data into value-field int v = atoi(value); current_tuple->attributes[k].value = &v; // for string values: current_tuple->attributes[k].type = DB_ATT_TYPE_STRING; current_tuple->attributes[k].value = value; } // ... } While I am perfectly aware, why this is not working, I can't figure out how to get it working. I've tried following things, none of which worked: memcpy(current_tuple->attributes[k].value, &v, sizeof(int)); This results in a bad access error. Same for the following code (since I'm not quite sure which one would be the correct usage): memcpy(current_tuple->attributes[k].value, &v, 1); Not even sure if memcpy is what I need here... Also I've tried allocating memory, by doing something like: current_tuple->attributes[k].value = (int *) malloc(sizeof(int)); only to get "malloc: * error for object 0x100108e98: incorrect checksum for freed object - object was probably modified after being freed." As far as I understand this error, memory has already been allocated for this object, but I don't see where this happened. Doesn't the malloc(sizeof(attribute)) only allocate the memory needed to store an integer and two pointers (i.e. not the memory those pointers point to)? Any help would be greatly appreciated!

• What's the best name for a non-mutating "add" method on an immutable collection?

  - by Jon Skeet

  Sorry for the waffly title - if I could come up with a concise title, I wouldn't have to ask the question. Suppose I have an immutable list type. It has an operation Foo(x) which returns a new immutable list with the specified argument as an extra element at the end. So to build up a list of strings with values "Hello", "immutable", "world" you could write: var empty = new ImmutableList<string>(); var list1 = empty.Foo("Hello"); var list2 = list1.Foo("immutable"); var list3 = list2.Foo("word"); (This is C# code, and I'm most interested in a C# suggestion if you feel the language is important. It's not fundamentally a language question, but the idioms of the language may be important.) The important thing is that the existing lists are not altered by Foo - so empty.Count would still return 0. Another (more idiomatic) way of getting to the end result would be: var list = new ImmutableList<string>().Foo("Hello"); .Foo("immutable"); .Foo("word"); My question is: what's the best name for Foo? EDIT 3: As I reveal later on, the name of the type might not actually be ImmutableList<T>, which makes the position clear. Imagine instead that it's TestSuite and that it's immutable because the whole of the framework it's a part of is immutable... (End of edit 3) Options I've come up with so far: Add: common in .NET, but implies mutation of the original list Cons: I believe this is the normal name in functional languages, but meaningless to those without experience in such languages Plus: my favourite so far, it doesn't imply mutation to me. Apparently this is also used in Haskell but with slightly different expectations (a Haskell programmer might expect it to add two lists together rather than adding a single value to the other list). With: consistent with some other immutable conventions, but doesn't have quite the same "additionness" to it IMO. And: not very descriptive. Operator overload for + : I really don't like this much; I generally think operators should only be applied to lower level types. I'm willing to be persuaded though! The criteria I'm using for choosing are: Gives the correct impression of the result of the method call (i.e. that it's the original list with an extra element) Makes it as clear as possible that it doesn't mutate the existing list Sounds reasonable when chained together as in the second example above Please ask for more details if I'm not making myself clear enough... EDIT 1: Here's my reasoning for preferring Plus to Add. Consider these two lines of code: list.Add(foo); list.Plus(foo); In my view (and this is a personal thing) the latter is clearly buggy - it's like writing "x + 5;" as a statement on its own. The first line looks like it's okay, until you remember that it's immutable. In fact, the way that the plus operator on its own doesn't mutate its operands is another reason why Plus is my favourite. Without the slight ickiness of operator overloading, it still gives the same connotations, which include (for me) not mutating the operands (or method target in this case). EDIT 2: Reasons for not liking Add. Various answers are effectively: "Go with Add. That's what DateTime does, and String has Replace methods etc which don't make the immutability obvious." I agree - there's precedence here. However, I've seen plenty of people call DateTime.Add or String.Replace and expect mutation. There are loads of newsgroup questions (and probably SO ones if I dig around) which are answered by "You're ignoring the return value of String.Replace; strings are immutable, a new string gets returned." Now, I should reveal a subtlety to the question - the type might not actually be an immutable list, but a different immutable type. In particular, I'm working on a benchmarking framework where you add tests to a suite, and that creates a new suite. It might be obvious that: var list = new ImmutableList<string>(); list.Add("foo"); isn't going to accomplish anything, but it becomes a lot murkier when you change it to: var suite = new TestSuite<string, int>(); suite.Add(x => x.Length); That looks like it should be okay. Whereas this, to me, makes the mistake clearer: var suite = new TestSuite<string, int>(); suite.Plus(x => x.Length); That's just begging to be: var suite = new TestSuite<string, int>().Plus(x => x.Length); Ideally, I would like my users not to have to be told that the test suite is immutable. I want them to fall into the pit of success. This may not be possible, but I'd like to try. I apologise for over-simplifying the original question by talking only about an immutable list type. Not all collections are quite as self-descriptive as ImmutableList<T> :)
