  • cpp/Qt : per class debugging

    - by dzen
    I'm developing a Qt application. For each class, I'm trying to mimic the framework, such as error() and errorString() method, use of Private implementation. But I would like to add a per class debugging: Set a macro to the desired level of debug, have a macro or a function that knows the level of debug, and use qDebug() or qWarning() which is class independant, and will know the current class's name (for some pretty prints) Anyone have a good idea to implement this ?

  • GCC how to block system calls within a program?

    - by CMPITG
    Does anyone tell me how to block system calls within a program, please? I am building a system which takes a piece of C source code, compiles it with gcc and runs it. For security reasons, I need to prevent the compiled program from calling system calls. Is there any way to do it, from the source code level (e.g. stripping the header files of gcc, detecting malicious external calls, ...) to the executable level?

  • What are the Options for Storing Hierarchical Data in a Relational Database?

    - by orangepips
    Good Overviews One more Nested Intervals vs. Adjacency List comparison: the best comparison of Adjacency List, Materialized Path, Nested Set and Nested Interval I've found. Models for hierarchical data: slides with good explanations of tradeoffs and example usage Representing hierarchies in MySQL: very good overview of Nested Set in particular Hierarchical data in RDBMSs: most comprehensive and well organized set of links I've seen, but not much in the way on explanation Options Ones I am aware of and general features: Adjacency List: Columns: ID, ParentID Easy to implement. Cheap node moves, inserts, and deletes. Expensive to find level (can store as a computed column), ancestry & descendants (Bridge Hierarchy combined with level column can solve), path (Lineage Column can solve). Use Common Table Expressions in those databases that support them to traverse. Nested Set (a.k.a Modified Preorder Tree Traversal) First described by Joe Celko - covered in depth in his book Trees and Hierarchies in SQL for Smarties Columns: Left, Right Cheap level, ancestry, descendants Compared to Adjacency List, moves, inserts, deletes more expensive. Requires a specific sort order (e.g. created). So sorting all descendants in a different order requires additional work. Nested Intervals Combination of Nested Sets and Materialized Path where left/right columns are floating point decimals instead of integers and encode the path information. Bridge Table (a.k.a. Closure Table: some good ideas about how to use triggers for maintaining this approach) Columns: ancestor, descendant Stands apart from table it describes. Can include some nodes in more than one hierarchy. Cheap ancestry and descendants (albeit not in what order) For complete knowledge of a hierarchy needs to be combined with another option. Flat Table A modification of the Adjacency List that adds a Level and Rank (e.g. ordering) column to each record. Expensive move and delete Cheap ancestry and descendants Good Use: threaded discussion - forums / blog comments Lineage Column (a.k.a. Materialized Path, Path Enumeration) Column: lineage (e.g. /parent/child/grandchild/etc...) Limit to how deep the hierarchy can be. Descendants cheap (e.g. LEFT(lineage, #) = '/enumerated/path') Ancestry tricky (database specific queries) Database Specific Notes MySQL Use session variables for Adjacency List Oracle Use CONNECT BY to traverse Adjacency Lists PostgreSQL ltree datatype for Materialized Path SQL Server General summary 2008 offers HierarchyId data type appears to help with Lineage Column approach and expand the depth that can be represented.

  • UML diagram for application architecture?

    - by fayer
    i'm trying to map my whole application in a UML diagram and i wonder what diagram type i should use. im not doing this in class level, rather from a bird eye's perspective. single application object (patterns: singleton)(examples: CodeIgniter application) that composes multiple module objects (patterns: singleton, facades)(examples: guestbook, addressbook) that compose multiple low level stand alone objects (examples: mysql mapper, doctrine mapper) that compose various 3rd and in-house libraries (examples: doctrine, solr, xml-parser) what UML diagram is suited for this kind of overview presentation? thanks

  • Updating DetailViewController from RootController

    - by Stefano Salmaso
    I'm trying to create an iPad application with a similar user interface to Apple's Mail application, i.e: RootView controller (table view) on the left hand side of the split view for navigation with a multiple view hierarchy. When a table cell is selected a new table view is pushed on the left hand side The new view on the left side can update the detail view. I can accomplish both tasks BUT NOT TOGETHER. I mean I can make a multi-level table view in the RootController.(HERE you can find the working source code). Or I can make a single-level table view in the RootController which can update the detailViewController (here there is the source code:http://www.megaupload.com/?d=D6L0463G). Can anyone tell me how to make a multi-level table in the RootController which can update a detailViewController? There is more source code at the link but below is the method in which I presume I have to declare a new detailViewController (which has to be put in the UISplitViewController): - (void)tableView:(UITableView *)TableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; // if([Children count] == 0) { /* Create and configure a new detail view controller appropriate for the selection. */ NSUInteger row = indexPath.row; UIViewController <SubstitutableDetailViewController> *detailViewController = nil; if (row == 0) { FirstDetailViewController *newDetailViewController = [[FirstDetailViewController alloc]initWithNibName:@"FirstDetailView" bundle:nil]; detailViewController = newDetailViewController; } if (row == 1) { SecondDetailViewController *newDetailViewController = [[SecondDetailViewController alloc]initWithNibName:@"SecondDetailView" bundle:nil]; detailViewController = newDetailViewController; } // Update the split view controller's view controllers array. NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil]; splitViewController.viewControllers = viewControllers//nothing happens..... [viewControllers release];// } else { //Prepare to tableview. RootViewController *rvController = [[RootViewController alloc]initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.current_level += 1; //Set the title; rvController.current_title = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController.tableView reloadData]; //without this instrucion,items won't be loaded inside the second level of the table [rvController release]; } }

  • SQL Server Transactions how can I commit my transaction

    - by codingguy3000
    I have SQL Server 2005 stored procedure. Someone one is calling my stored procedure within a transaction. In my stored proc I'm logging some information (insert into a table). When the higher level transaction rolls back it removes my insert. Is there anyway I can commit my insert and prevent the higher level rollback from removing my insert? Thanks

  • gcc - using -werror and -std= -pedantic considered good practice?

    - by Helper Method
    I'm just digging into the gcc manual and some things are still unclear to me: a) When specifying a std, should I always use -pedantic in conjunction? b) When using -g, it the standard level sufficient or should I specify level 3, i.e. -g3? c) Is it good practice to use -Werror to promote all warnings to errors and -pedantic-errors to promote all pedantic warnings to errors?

  • web (server) based password manager

    - by laurens
    Hi all! I know there have been a few topics here about password managers but I read them all and did not really find what I'm looking for. What I'd need is a free or cheap (most password mgr software is $500 for 20+ users, exaggerated!) multi-user password manager, highly preferable web-based so that we can host it on one of our local server, of Hyper-V VM's. So: -free or cheap ( <100$) -multi-user of groups -web based -not very hard to install I tried a few, one very expensive, one I did not get to work- Web Keepass Manager This works with tomcat and probably conflicts with our IIS 7.0 or 7.5 PS: thus, nothing online (!) it has to stay local Thanks in advance!

  • m2eclipse sets JDK compliance to 1.4

    - by jihedamine
    Using eclipse 3.5, when I create a new maven project, m2eclipse automatically adds J2SE1.4 to libraries and Compiler Compliance Level to 1.4 (Project properties Java Compiler). My JRE system library is 1.6 and my default compiler compliance level is 1.6. I don't even have 1.4 installed. Can I make m2eclipse use my default settings and prevent it from modifying project settings?

  • Is there a way to control two instantiated systemd services as a single unit?

    - by rascalking
    I've got a couple python web services I'm trying to run on a Fedora 15 box. They're being run by paster, and the only difference in starting them is the config file they read. This seems like a good fit for systemd's instantiated services, but I'd like to be able to control them as a single unit. A systemd target that requires both services seems like the way to approach that. Starting the target does start both services, but stopping the target leaves them running. Here's the service file: [Unit] Description=AUI Instance on Port %i After=syslog.target [Service] WorkingDirectory=/usr/local/share/aui ExecStart=/opt/cogo/bin/paster serve --log-file=/var/log/aui/%i deploy-%i.ini Restart=always RestartSec=2 User=aui Group=aui [Install] WantedBy=multi-user.target And here's the target file: [Unit] Description=AUI [email protected] [email protected] After=syslog.target [Install] WantedBy=multi-user.target Is this kind of grouping even possible with systemd?

    Is there a way to implement the null object design pattern in a generic form so that i don't need to implement it for every buisness object. For me, there are two high level classes you'll need for every business class. One for a single record and another for a list. So i think there should be a way to implement the NULL Object design pattern at a high level and not have to implement it for every class. Is there a way and how please?

    When using Ehcache with Hibernate, is there a way to specify region names with wildcards in the ehcache.xml file? For example, to allow for cache settings at the package level (with * as a wildcard indicator): <cache name="com.example.my.package1.*" ... /> <cache name="com.example.my.package2.*" ... /> (Note: The package-level distinction is just an example. My question is to wildcards in the general case.)

  • Has anyone tried the "objectify" library for Google App Engine?

    - by Spines
    I was using JDO for my google app engine project but got fed up with the additional 5 seconds it adds to my cold start time. I was planning on just writing stuff directly to the database with the low level datastore api, but then I came accross the objectify project ( http://code.google.com/p/objectify-appengine/ ). Apparently its a super light wrapper above the low level api. Does anyone have experiences with this library that they could share?
