  • Visual Studio 2008 project file does not load because of an unexpected encoding change.

    - by Xenan
    In our team we have a database project in visual Studio 2008 which is under source control by Team Foundation Server. Every two weeks or so, after one co-worker checks in, the project file won't load on the other developers machines. The error message is: The project file could not be loaded. Data at the root level is invalid. Line 1, position 1. When I look at the project file in Notepad++, the file looks like this: ??<NUL?NULxNULmNULlNUL NULvNULeNULrNULsNULiNULoNULnNUL ... and so on (you can see <?xml version in this) whereas an normal project file looks like: <?xml version="1.0" encoding="utf-16"?> ... So probably something is wrong with the encoding of the file. This is a problem for us because it turns out to be impossible to get the file encoding correct again. The 'solution' is to throw away the project file an get the last know working version from source control. According to the file, the encoding should be UTF-16. According to Notepad++, the corrupted file is actually UTF-8. My questions are: Why is Visual Studio messing up the encoding of the project file, apparently at random times and at random machines? What should we do to prevent this? When it has happened, is there a possibility to restore the current file in the correct encoding instead of pulling an older version from source control? As a last note: the problem is with one single project file, all other project files don't expose this problem.

  • jQuery - I'm getting unexpected outputs from a basic math formula.

    - by OllieMcCarthy
    Hi I would like to start by saying I'd greatly appreciate anyones help on this. I have built a small caculator to calculate the amount a consumer can save annually on energy by installing a ground heat pump or solar panels. As far as I can tell the mathematical formulas are correct and my client verified this yesterday when I showed him the code. Two problems. The first is that the calculator is outputting ridiculously large numbers for the first result. The second problem is that the solar result is only working when there are no zeros in the fields. Are there some quirks as to how one would write mathematical formulas in JS or jQuery? Any help greatly appreciated. Here is the link - http://www.olliemccarthy.com/test/johncmurphy/?page_id=249 And here is the code for the entire function - $jq(document).ready(function(){ // Energy Bill Saver // Declare Variables var A = ""; // Input for Oil var B = ""; // Input for Storage Heater var C = ""; // Input for Natural Gas var D = ""; // Input for LPG var E = ""; // Input for Coal var F = ""; // Input for Wood Pellets var G = ""; // Input for Number of Occupants var J = ""; var K = ""; var H = ""; var I = ""; // Declare Constants var a = "0.0816"; // Rate for Oil var b = "0.0963"; // Rate for NightRate var c = "0.0558"; // Rate for Gas var d = "0.1579"; // Rate for LPG var e = "0.121"; // Rate for Coal var f = "0.0828"; // Rate for Pellets var g = "0.02675"; // Rate for Heat Pump var x = "1226.4"; // Splittin up I to avoid error var S1 = ""; // Splitting up the calcuation for I var S2 = ""; // Splitting up the calcuation for I var S3 = ""; // Splitting up the calcuation for I var S4 = ""; // Splitting up the calcuation for I var S5 = ""; // Splitting up the calcuation for I var S6 = ""; // Splitting up the calcuation for I // Calculate H (Ground Sourced Heat Pump) $jq(".es-calculate").click(function(){ $jq(".es-result-wrap").slideDown(300); A = $jq("input.es-oil").val(); B = $jq("input.es-storage").val(); C = $jq("input.es-gas").val(); D = $jq("input.es-lpg").val(); E = $jq("input.es-coal").val(); F = $jq("input.es-pellets").val(); G = $jq("input.es-occupants").val(); J = ( A / a ) + ( B / b ) + ( C / c ) + ( D / d ) + ( E / e ) + ( F / f ) ; H = A + B + C + D + E + F - ( J * g ) ; K = ( G * x ) ; if ( A !== "0" ) { S1 = ( ( ( A / a ) / J ) * K * a ) ; } else { S1 = "0" ; } if ( B !== "0" ) { S2 = ( ( ( B / b ) / J ) * K * b ) ; } else { S2 = "0" ; } if ( C !== "0" ) { S3 = ( ( ( C / c ) / J ) * K * c ) ; } else { S3 = "0" ; } if ( D !== "0" ) { S4 = ( ( ( D / d ) / J ) * K * d ) ; } else { S4 = "0" ; } if ( E !== "0" ) { S5 = ( ( ( E / e ) / J ) * K * e ) ; } else { S5 = "0" ; } if ( F !== "0" ) { S6 = ( ( ( F / f ) / J ) * K * f ) ; } else { S6 = "0" ; } I = S1 + S2 + S3 + S4 + S5 + S6 ; if(!isNaN(H)) {$jq("span.es-result-span-h").text(H.toFixed(2));} else{$jq("span.es-result-span-h").text('Error: Please enter numerals only');} if(!isNaN(I)) {$jq("span.es-result-span-i").text(I.toFixed(2));} else{$jq("span.es-result-span-i").text('Error: Please enter numerals only');} }); });

  • NHibernate's ISQLQuery returns instances that are of an unexpected type.

    - by Frederik Gheysels
    Hi all, I'm using NHibernate 2.1.2.400, and I'm having an issue with a an ISQLQuery query. The reason why I use an ISQLQuery here, is that this query uses a table for which I have no entity mapped in NHibernate. The query looks like this: ISQLQuery query = session.CreateSQLQuery ( "select p.*, price.* " + "from prestation p left outer join prestationprice price on p.PrestationId = price.PrestationId " + "where p.Id IN ( select id from prestationregistry where ..."); 'Prestationregistry' is the table that is not known by NHibernate (unmapped, so therefore the native SQL Query). my code continues like this: query.AddEntity ("p", typeof(Prestation)); query.AddJoin ("price", typeof(PrestationPrice)); query.SetResultTransformer (Transformers.DistinctRootEntity); var result = query.List(); So far so good. I expect that I'm given a list of 'Prestation' instances as a result of this query, since I declared 'Prestation' as being the root-object that has to be returned by the AddEntity method. I also expect that the PrestationPrices for each Prestation are eagerly loaded by this query (hence the AddJoin method). To my surprise, the List() method returns a collection of PrestationPrice instances instead of Prestation instances. How come ? Am I doing something wrong ? And if so, could you be so kind to tell me what I'm doing wrong ? Edit: Additional Info: When I debug, and put a watch on the 'query' instance, I can see that the queryReturns member of the query contains 2 items: - one NativeSqlQueryRootReturn instance who'se ReturnEntityName is 'Prestation' - one NativeSqlQueryJoinReturn When I do not specify the 'DistinctRootEntity' result transformer, the query returns instances of 'Prestation' instead of PrestationPrice. However, it contains multiple copies of the same instance.

  • How to shutdown local tomcat server when closing browser window?

    - by agez
    Hi, I hava a web app running on a local tomcat server. When the user starts the app (via desktop shortcut) the server starts and the app is opened in a browser window. But when the user just clicks on the close button to stop the application the server is still running in the background - that's annoying. I tried to utilize the "unonload" and "onbeforeunload" events from javascript but unfortunately these events are also fired on some other requests in the app. So I can't use them, except I do a lot of refactoring. Does anyone have an idea for a possible solution? Btw, what I find interesting is the behaviour of Visual Studio when debugging a web application. When I close the browser window Visual Studio also gets a trigger to stop debug mode. So it seems it somehow notices the close event of the browser window, which would be exactly what I need. But I don't know how they do it... Cheers, Helmut

  • Unexpected results when looking at ASCII codes in C++.

    - by Columbo
    Hello, The bit of code below is extracting ASCII codes from characters. When I convert characters in the normal ASCII region I get the value I expect. When I convert £ and € from the extened region I get a load of 1's padding the INT that I'm storing the character in. e.g. the output of the below is: 45 (ascii E as expected) FFFFFF80 (extended ascii € as expected but padded with ones) It's not causing me an issue but I'm just wondering why this happens. Here's the code... unsigned int asciichar[3]; string cTextToEncode = "E€"; for (unsigned int i = 0; i < cTextToEncode.length(); i++) { asciichar[i] = (unsigned int)cTextToEncode[i]; cout << hex << asciichar[i] << "\n"; } Can anyone explain why this is? Thanks

  • I am trying to access the individual bytes in a floating point number and I am getting unexpected results

    - by oweinh
    So I have this so far: #include <iostream> #include <string> #include <typeinfo> using namespace std; int main () { float f = 3.45; // just an example fp# char* ptr = (char*)&f; // a character pointer to the first byte of the fp#? cout << int(ptr[0]) << endl; // these lines are just to see if I get what I cout << int(ptr[1]) << endl; // am looking for... I want ints that I can cout << int(ptr[2]) << endl; // otherwise manipulate. cout << int(ptr[3]) << endl; } the result is: -51 -52 92 64 so obviously -51 and -52 are not in the byte range that I would expect for a char... I have taken information from similar questions to arrive at this code and from all discussions, a conversion from char to int is straightforward. So why negative values? I am trying to look at a four-byte number, therefore I would expect 4 integers, each in the range 0-255. I am using Codeblocks 13.12 with gcc 4.8.1 with option -std=C++11 on a Windows 8.1 device.

  • How to play an .mp3 using QBuffer with Phonon in a PyQt Qt environment

    - by thedax
    With the code I have right now I CAN play .mp3 data from files succesfully. However I need to play the same data using a QtCore.QBuffer (NOT from a file). When I use the example of the docs it errors an unexpected type of QBuffer! However...... that is what it SHOULD see, according to the docs. But............... it throws: TypeError: Phonon.MediaObject.setCurrentSource(Phonon.MediaSource): argument 1 has unexpected type 'QBuffer' The code I use is (1): someBuffer = QtCore.QBuffer() someBuffer.writeData(TrackData) mediaObject.setCurrentSource(someBuffer) I also tried (2): someBuffer = QtCore.QBuffer() mediaObject.setCurrentSource(someBuffer) someBuffer.writeData(TrackData) and (3): someBuffer = QtCore.QBuffer() someBuffer.writeData(TrackData) mediaObject.setCurrentSource(Phonon.MediaSource(someBuffer)) The last example (3) throws an different ERROR and wipes my Gui off screen ;-) ASSERT: "d-connected" in file /builddir/build/BUILD/phonon-4.5.1/phonon/streaminterface.cpp, line xxxx Notes: TrackData contains the mp3 data and IS PLAYING OK when I write it to a File and use that as a resource to mediaObject.setCurrentSource(Phonon.MediaSource())I also experimented with a QByteArray but that leads to the same "unexpected QBuffer" error. To be more precise everything I feed setCurrentSource is not accepted. Tried a string (errors an unexpected type of String), tried a QBuffer (errors an unexpected type of QBuffer), tried a QByteArray (errors an unexpected type of QByteArray). BTW: I run Qt, PyQt on Linux. Any ideas??

  • Software Architecture Analysis Method (SAAM)

    Software Architecture Analysis Method (SAAM) is a methodology used to determine how specific application quality attributes were achieved and how possible changes in the future will affect quality attributes based on hypothetical cases studies. Common quality attributes that can be utilized by this methodology include modifiability, robustness, portability, and extensibility. Quality Attribute: Application Modifiability The Modifiability quality attribute refers to how easy it changing the system in the future will be. This to me is a very open-ended attribute because a business could decide to transform a Point of Sale (POS) system in to a Lead Tracking system overnight. (Yes, this did actually happen to me) In order for SAAM to be properly applied for checking this attribute specific hypothetical case studies need to be created and review for the modifiability attribute due to the fact that various scenarios would return various results based on the amount of changes. In the case of the POS change out a payment gateway or adding an additional payment would have scored very high in comparison to changing the system over to a lead management system. I personally would evaluate this quality attribute based on the S.O.I.L.D Principles of software design. I have found from my experience the use of S.O.I.L.D in software design allows for the adoption of changes within a system. Quality Attribute: Application Robustness The Robustness quality attribute refers to how an application handles the unexpected. The unexpected can be defined but is not limited to anything not anticipated in the originating design of the system. For example: Bad Data, Limited to no network connectivity, invalid permissions, or any unexpected application exceptions. I would personally evaluate this quality attribute based on how the system handled the exceptions. Robustness Considerations Did the system stop or did it handle the unexpected error? Did the system log the unexpected error for future debugging? What message did the user receive about the error? Quality Attribute: Application Portability The Portability quality attribute refers to the ease of porting an application to run in a new operating system or device. For example, It is much easier to alter an ASP.net website to be accessible by a PC, Mac, IPhone, Android Phone, Mini PC, or Table in comparison to desktop application written in VB.net because a lot more work would be involved to get the desktop app to the point where it would be viable to port the application over to the various environments and devices. I would personally evaluate this quality attribute based on each new environment for which the hypothetical case study identifies. I would pay particular attention to the following items. Portability Considerations Hardware Dependencies Operating System Dependencies Data Source Dependencies Network Dependencies and Availabilities  Quality Attribute: Application Extensibility The Extensibility quality attribute refers to the ease of adding new features to an existing application without impacting existing functionality. I would personally evaluate this quality attribute based on each new environment for the following Extensibility  Considerations Hard coded Variables versus Configurable variables Application Documentation (External Documents and Codebase Documentation.) The use of Solid Design Principles

  • MySQL InnoDB disappeared, all InnoDB data cant be accessed

    - by dogmatic69
    Mysql (including InnoDB) was working fine, after a restart the other day when mysql starts it says in the logs: 140604 23:36:07 [Note] Plugin 'FEDERATED' is disabled. 140604 23:36:07 [Note] Plugin 'InnoDB' is disabled. In the app it says: SQLSTATE[42000]: Syntax error or access violation: 1286 Unknown storage engine 'InnoDB' Now, according to google this is a very simple fix, just remove the ib_logfile[0|1] files, which I have done and does not do anything.

  • How to properly deny Railo directory access through Apache

    - by Sn3akyP3t3
    I've been battle tested on this and failed to achieve my goal which is to deny all access to all directories except the Public directory and only allow access to all all other directories with specific IP addresses. To get Railo+Apache+Tomcat installed I pretty much followed this script: https://github.com/talltroym/Railo-Ubuntu-Installer-Script then verified settings with this tutorial: http://blog.nictunney.com/2012/03/railo-tomcat-and-apache-on-amazon-ec2.html From the installation script these mods are enabled: sudo a2enmod ssl sudo a2enmod proxy sudo a2enmod proxy_http sudo a2enmod rewrite sudo a2ensite default-ssl Outside of the script I copied the sites-available to sites-enabled then reloaded Apache. I have a directory created for Railo cmfl located at /var/www/Railo/ Navigating the browser to http ://Server_IP_Address/Railo forces ssl and relocates to https ://Server_IP_Address/Railo which shows off index.cfm. Not providing index.cfm and omitting https indicates that the DirectoryIndex directive and RewriteCond of Apache appears to be working for the sites-enabled VirtualHost. The problem I'm encountering is that I cannot seem to deny access to all directories except Public. My directory structure is rather simple and looks like this: Railo error Public NotPublic Sandbox These are my sites-enabled configurations: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www #Default Deny All to prevent walking backwards in file system Alias /Railo/ "/var/www/Railo/" <Directory ~ ".*/Railo/(?!Public).*"> Order Deny,Allow Deny from All </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

When you need a different shutdown # approach you can use one of the following variables: # o ssl-unclean-shutdown: # This forces an unclean shutdown when the connection is closed, i.e. no # SSL close notify alert is send or allowed to received. This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too. Use variable "nokeepalive" for this. # Similarly, one has to force some clients to use HTTP/1.0 to workaround # their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and # "force-response-1.0" for this. BrowserMatch "MSIE [2-6]" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 # MSIE 7 and newer should be able to use keepalive BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown DirectoryIndex index.cfm index.cfml default.cfm default.cfml index.htm index.html #Proxy .cfm and cfc requests to Railo ProxyPassMatch ^/(.+.cf[cm])(/.*)?$ http://127.0.0.1:8888/$1 ProxyPassReverse / http://127.0.0.1:8888/ #Deny access to admin except for local clients <Location /railo-context/admin/> Order deny,allow Deny from all # Allow from <Omitted> # Allow from <Omitted> Allow from 127.0.0.1 </Location> </VirtualHost> </IfModule> The apache2.conf includes the following: # Include the virtual host configurations: Include sites-enabled/ <IfModule !mod_jk.c> LoadModule jk_module /usr/lib/apache2/modules/mod_jk.so </IfModule> <IfModule mod_jk.c> JkMount /*.cfm ajp13 JkMount /*.cfc ajp13 JkMount /*.do ajp13 JkMount /*.jsp ajp13 JkMount /*.cfchart ajp13 JkMount /*.cfm/* ajp13 JkMount /*.cfml/* ajp13 # Flex Gateway Mappings # JkMount /flex2gateway/* ajp13 # JkMount /flashservices/gateway/* ajp13 # JkMount /messagebroker/* ajp13 JkMountCopy all JkLogFile /var/log/apache2/mod_jk.log </IfModule> I believe I understand most of this except the jk_module inclusion which I've noticed has an error that shows up in the logs that I can't sort out: [warn] No JkShmFile defined in httpd.conf. Using default /etc/apache2/logs/jk-runtime-status I've checked my Regular expression against the paths of the directories with RegexBuddy just to be sure that I wasn't correct. The problem doesn't appear to be Regex related although I may have something incorrect in the Directory directive. The Location directive seems to be working correctly for blocking out Railo admin site access.

  • Select (loop) or command not working in shell-script

    - by user208098
    I've been tinkering with Linux and Unix for years but still a novice in my mind and recently find myself trying to be more pro with it as I work in IT. So with that notion I'm studying shell scripting. I've hit a snag in ubuntu using the latest version 13.10 Saucy. When I use the select command in a sh script it doesn't work, depending on how I format the command it will either return Unexpected "do" or Unexpected "done". See the following two examples: This section of code produces an unexpected "do" error: #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit do case $opt in "option1") echo "you chose choice 1" ;; "option2") echo "you chose choice 2" ;; "option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done This section of code produces an unexpected "done" error. #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit ; do case $opt in "Option1") echo "you chose choice 1" ;; "Option2") echo "you chose choice 2" ;; "Option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done When I enter these parameters into the command line interactively or manually I get the desired result which is a list of choices to choose from. However when executed from a script I get the before mentioned errors. Also a side note I have tried this in Fedora as a script and it worked perfectly so my question is why isn't it working in Ubuntu, is this a difference between RHL and Debian? Or is it a bug in the latest version of Ubuntu? Thanks in advance for any help! KG

  • Black login screen Ubuntu 12.04 if WGA cable pluged in on reboot

    - by Sulliwane
    I'm using Ubuntu 12.04.1, 64 bits, installed on a Z77 Pro4 (ASrock motherboard), crucial M4 SSD drive (sata 3), and intel i5 3570k (ivy bridge). I have this annoying problem : When I startup the computer, I get a CLI login prompt : At this moment, if I press enter, i get the usual CLI login prompt. If not, here is what I get : From now, if I login using CLI, i identify the lightdm processus, kill and start it : #ps -A | grep lightdm #sudo kill -9 1273 #sudo lightdm and miracle, these commands bring back the gui login screen. BUT It's very annoying as I have to repeat these steps at every boot, and the people using this desktop are not familiar with linux at all! So I tried to figure out the cause and here is what I found : If, when I shutdown the computer, the WGA cable is not pluged in, then Ubuntu will boot on GUI login screen without a glitch! But If the WGA cable is pluged in when shuting down, I will get CLI login prompt... Note 1: I installed linux kernel 3.4, but it hasn't solve the problem. Note 2: Is it linked to the new HD 4000 integrated graphic processor ? Note 3: If i boot on an USB stick (Ubuntu 12.04), NO problems ! Note 4: If booting on the SSD, when clicking "shutdown" button, the shutdown process never ends up (logout screen keep displaying and fans are still rolling). But if booting on USB stick, the shutdown action runs properly.

  • horizontal line across screen at startup

    - by Debbie Poole
    I recently ran an upgrade from 12.04 to 12.10 and was using Nvidia current tested drivers and all seemed ok at first. Then suddenly every time I started the computer and shutdown, the graphical plymouth logo changed to text.The only changes I made to try to correct this issue were; sudo apt-get --purge remove nvidia-current nvidia-settings sudo apt-get --purge autoremove sudo apt-get clean sudo apt-get update sudo apt-get install nvidia-current and this made no change at all to the display. Then I read somewhere that Nouveau drivers may be the answer, so I installed them to use instead, and hey presto, the shutdown screen displays the Plymouth splash. However with startup, I get a stable purple screen, for a while, and than a thick black horizontal line appears, really ugly-looking, and then the loging screen appears to be ok. Can I correct the login screen same as the shutdown screen?

  • WUBI install not completing on Dell Latitude D600 using 10.04 and 10.10

    - by Dennis
    While trying to install a dual boot from LiveCD, WUBI seems to go through all the steps correctly. It unpacks everything, reboots, starts to finalize the install, brings up the install slide show and seems to do everything necessary. The slide show disappears and what is left is what would normally be the background, however there is no login, no panels, no response to any input or keystrokes. Using 10.04 I had a mouse cursor (working) with 10.10, not even that. In 10.04 The only way to reboot is to shutdown using the power switch. When it reboots it goes through the "finalizing install" phase again. In 10.10 if I hit the power switch it brings up a shutdown menu that doesn't respond to the keyboard, but does shutdown when the 60 seconds expire.

  • Ubuntu Wubi Booting Problem

    - by D3s7
    i have a problem with my Ubuntu 12.04 Wubi installation, sometimes when booting, the computer will get to the purple screen without the Ubuntu logo, then will go to a black screen and then lots of white saccaged colors will appear and i will be taken to the login page. But sometimes, it just get stuck on the black screen and does nothing and i have to hard shutdown and retry it until it works. What may cause this problem and why? I can shutdown correctly. Thanks for helping. Edit: RADEON HD 7650M Graphic card with latest available Drivers on amd's driver download site (fglrx drivers caused shutdown problems so i removed them). Screen resolution is 1600x900.

  • Plagued by multithreaded bugs

    - by koncurrency
    On my new team that I manage, the majority of our code is platform, TCP socket, and http networking code. All C++. Most of it originated from other developers that have left the team. The current developers on the team are very smart, but mostly junior in terms of experience. Our biggest problem: multi-threaded concurrency bugs. Most of our class libraries are written to be asynchronous by use of some thread pool classes. Methods on the class libraries often enqueue long running taks onto the thread pool from one thread and then the callback methods of that class get invoked on a different thread. As a result, we have a lot of edge case bugs involving incorrect threading assumptions. This results in subtle bugs that go beyond just having critical sections and locks to guard against concurrency issues. What makes these problems even harder is that the attempts to fix are often incorrect. Some mistakes I've observed the team attempting (or within the legacy code itself) includes something like the following: Common mistake #1 - Fixing concurrency issue by just put a lock around the shared data, but forgetting about what happens when methods don't get called in an expected order. Here's a very simple example: void Foo::OnHttpRequestComplete(statuscode status) { m_pBar->DoSomethingImportant(status); } void Foo::Shutdown() { m_pBar->Cleanup(); delete m_pBar; m_pBar=nullptr; } So now we have a bug in which Shutdown could get called while OnHttpNetworkRequestComplete is occuring on. A tester finds the bug, captures the crash dump, and assigns the bug to a developer. He in turn fixes the bug like this. void Foo::OnHttpRequestComplete(statuscode status) { AutoLock lock(m_cs); m_pBar->DoSomethingImportant(status); } void Foo::Shutdown() { AutoLock lock(m_cs); m_pBar->Cleanup(); delete m_pBar; m_pBar=nullptr; } The above fix looks good until you realize there's an even more subtle edge case. What happens if Shutdown gets called before OnHttpRequestComplete gets called back? The real world examples my team has are even more complex, and the edge cases are even harder to spot during the code review process. Common Mistake #2 - fixing deadlock issues by blindly exiting the lock, wait for the other thread to finish, then re-enter the lock - but without handling the case that the object just got updated by the other thread! Common Mistake #3 - Even though the objects are reference counted, the shutdown sequence "releases" it's pointer. But forgets to wait for the thread that is still running to release it's instance. As such, components are shutdown cleanly, then spurious or late callbacks are invoked on an object in an state not expecting any more calls. There are other edge cases, but the bottom line is this: Multithreaded programming is just plain hard, even for smart people. As I catch these mistakes, I spend time discussing the errors with each developer on developing a more appropriate fix. But I suspect they are often confused on how to solve each issue because of the enormous amount of legacy code that the "right" fix will involve touching. We're going to be shipping soon, and I'm sure the patches we're applying will hold for the upcoming release. Afterwards, we're going to have some time to improve the code base and refactor where needed. We won't have time to just re-write everything. And the majority of the code isn't all that bad. But I'm looking to refactor code such that threading issues can be avoided altogether. One approach I am considering is this. For each significant platform feature, have a dedicated single thread where all events and network callbacks get marshalled onto. Similar to COM apartment threading in Windows with use of a message loop. Long blocking operations could still get dispatched to a work pool thread, but the completion callback is invoked on on the component's thread. Components could possibly even share the same thread. Then all the class libraries running inside the thread can be written under the assumption of a single threaded world. Before I go down that path, I am also very interested if there are other standard techniques or design patterns for dealing with multithreaded issues. And I have to emphasize - something beyond a book that describes the basics of mutexes and semaphores. What do you think? I am also interested in any other approaches to take towards a refactoring process. Including any of the following: Literature or papers on design patterns around threads. Something beyond an introduction to mutexes and semaphores. We don't need massive parallelism either, just ways to design an object model so as to handle asynchronous events from other threads correctly. Ways to diagram the threading of various components, so that it will be easy to study and evolve solutions for. (That is, a UML equivalent for discussing threads across objects and classes) Educating your development team on the issues with multithreaded code. What would you do?
