• gcc : Is using -Werror and -pedantic considered good practice?

  - by Helper Method

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

• Errata for Java Language Specification 3rd Edition

  - by polygenelubricants

  I use JLS extensively both as a learning and teaching resource, but I've noticed that there are some errors in it. There's the simple typos (e.g. JLS 5.1.4 "convesions"), but there's also some that I consider quite serious errors. For example, JLS 18.1 The Grammar of the Java Programming Language is supposed to be the authoritative reference for the grammar of the Java language, but it contains a production rule that never gets used! (e.g. MoreStatementExpressions). Surely this is a sign of more serious errors in other parts of the given grammar, right? So is there an errata for the 3rd edition? Will there ever be? Should we send errors we've found to Sun/Oracle? Will there ever be a 4th edition?

• Why is the latency on one LVM volume consistently higher?

  - by David Schmitt

  I've got a server with LVM over RAID1. One of the volumes has a consistently higher IO latency (as measured by the diskstats_latency munin plugin) than the other volumes from the same group. As you can see, the dark orange /root volume has consistently high IO latency. Actually ten times the average latency of the physical devices. It also has the highest Min and Max values. My main concern are not the peaks, which occur under high load, but the constant load on (semi-)idle. The server is running Debian Squeeze with the VServer kernel and has four VServer containers and one KVM guest. I'm looking for ways to fix - or at least understand - this situation. Here're some parts of the system configuration: root@kvmhost2:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/system--host-root 19G 3.8G 14G 22% / tmpfs 16G 0 16G 0% /lib/init/rw udev 16G 224K 16G 1% /dev tmpfs 16G 0 16G 0% /dev/shm /dev/md0 942M 37M 858M 5% /boot /dev/mapper/system--host-isos 28G 19G 8.1G 70% /srv/isos /dev/mapper/system--host-vs_a 30G 23G 6.0G 79% /var/lib/vservers/a /dev/mapper/system--host-vs_b 5.0G 594M 4.1G 13% /var/lib/vservers/b /dev/mapper/system--host-vs_c 5.0G 555M 4.2G 12% /var/lib/vservers/c /dev/loop0 4.4G 4.4G 0 100% /media/debian-6.0.0-amd64-DVD-1 /dev/loop1 4.4G 4.4G 0 100% /media/debian-6.0.0-i386-DVD-1 /dev/mapper/system--host-vs_d 74G 55G 16G 78% /var/lib/vservers/d root@kvmhost2:~# cat /proc/mounts rootfs / rootfs rw 0 0 none /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 none /proc proc rw,nosuid,nodev,noexec,relatime 0 0 none /dev devtmpfs rw,relatime,size=16500836k,nr_inodes=4125209,mode=755 0 0 none /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 /dev/mapper/system--host-root / ext3 rw,relatime,errors=remount-ro,data=ordered 0 0 tmpfs /lib/init/rw tmpfs rw,nosuid,relatime,mode=755 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev,relatime 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 /dev/md0 /boot ext3 rw,sync,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-isos /srv/isos ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_a /var/lib/vservers/a ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_b /var/lib/vservers/b ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_c /var/lib/vservers/c ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/loop0 /media/debian-6.0.0-amd64-DVD-1 iso9660 ro,relatime 0 0 /dev/loop1 /media/debian-6.0.0-i386-DVD-1 iso9660 ro,relatime 0 0 /dev/mapper/system--host-vs_d /var/lib/vservers/d ext3 rw,relatime,errors=continue,data=ordered 0 0 root@kvmhost2:~# cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sda2[0] sdb2[1] 975779968 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 979840 blocks [2/2] [UU] unused devices: <none> root@kvmhost2:~# iostat -x Linux 2.6.32-5-vserver-amd64 (kvmhost2) 06/28/2012 _x86_64_ (8 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 3.09 0.14 2.92 1.51 0.00 92.35 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 23.25 161.12 7.46 37.90 855.27 1596.62 54.05 0.13 2.80 1.76 8.00 sdb 22.82 161.36 7.36 37.66 850.29 1596.62 54.35 0.54 12.01 1.80 8.09 md0 0.00 0.00 0.00 0.00 0.14 0.02 38.44 0.00 0.00 0.00 0.00 md1 0.00 0.00 53.55 198.16 768.01 1585.25 9.35 0.00 0.00 0.00 0.00 dm-0 0.00 0.00 0.48 20.21 16.70 161.71 8.62 0.26 12.72 0.77 1.60 dm-1 0.00 0.00 3.62 10.03 28.94 80.21 8.00 0.19 13.68 1.59 2.17 dm-2 0.00 0.00 0.00 0.00 0.00 0.00 9.17 0.00 9.64 6.42 0.00 dm-3 0.00 0.00 6.73 0.41 53.87 3.28 8.00 0.02 3.44 0.12 0.09 dm-4 0.00 0.00 17.45 18.18 139.57 145.47 8.00 0.42 11.81 0.76 2.69 dm-5 0.00 0.00 2.50 46.38 120.50 371.07 10.06 0.69 14.20 0.46 2.26 dm-6 0.00 0.00 0.02 0.10 0.67 0.81 12.53 0.01 75.53 18.58 0.22 dm-7 0.00 0.00 0.00 0.00 0.00 0.00 7.99 0.00 11.24 9.45 0.00 dm-8 0.00 0.00 22.69 102.76 407.25 822.09 9.80 0.97 7.71 0.39 4.95 dm-9 0.00 0.00 0.06 0.08 0.50 0.62 8.00 0.07 481.23 11.72 0.16 root@kvmhost2:~# ls -l /dev/mapper/ total 0 crw------- 1 root root 10, 59 May 11 11:19 control lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm1 -> ../dm-4 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm2 -> ../dm-3 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-isos -> ../dm-2 lrwxrwxrwx 1 root root 7 May 11 11:19 system--host-root -> ../dm-0 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-swap -> ../dm-9 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_d -> ../dm-8 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_b -> ../dm-6 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_c -> ../dm-7 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_a -> ../dm-5 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm3 -> ../dm-1 root@kvmhost2:~#

• adding multiple rows to jquery Datatables dynamically

  - by arrowill12

  I am trying to add multiple rows at once to a jQuery Datatable. I would like to be able to create a string such as the one below and call a function to add these elements as rows in the table. Is there a function that will allow me to do this? var trString = "<tr class='custom class'><td></td><td></td></tr><tr class='custom class'><td></td><td></td></tr><tr class='custom class'><td></td><td></td></tr>" I have seen the fnAddData function but I would not be able to add my custom classes dynamically to the rows using that function. Also I have tried fnAddTr but I keep receiving an error saying my object does not have the method "getelementsByTagName" again, is there a function that will allow me to add a string of "" to a datatable?

• Netbeans (PHP) catching syntax error on xml declaration

  - by Mike Valeriano

  Hello. I've just installed and configured Netbeans to work with PHP (including xdebug), and almost everything is working as intended, except that I've been getting "errors" in the IDE after I edited the default webpage template to comply with xhtml 1.1. The template is this: <?xml version="1.0" encoding="${project.encoding}" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=${project.encoding}" /> <title></title> </head> <body> </body> </html> These are the errors I receive (I can't post images yet). Page is created OK, character encoding is inherited from project's settings as expected. It's probably something to do with the xml declaration on top of the document, but I don't really know how to "tune" Netbeans to ignore it and not show the 3 errors on every page I create. The warning is there because NB does not recognize the xhtml 1.1 DTD, so it falls back to html 4.01, which does not support the xmlns attribute in the html tag - and that's the only thing I could find searching around. It will be fixed in the next version, so I'm not worried about it. I know there's nothing wrong with the markup, but there's probably something I'm missing in NB configuration, and I would like to get rid of those messages because they pretty much take all the space I reserve for errors/warnings/tasks. So is there any way I can either make NB recognize this xml declaration or make it ignore these specific "errors"? Thanks.

• How do you use vim's quickfix feature?

  - by hora

  I'm a pretty new Vim user and I've found that its learning curve is quite steep (at least for me). I just installed this vim script for JavaScriptLint error checking, which shows errors in vim's quickfix window once I save a buffer. However, I don't know what to do next.. How do I 'scroll' through all the errors? How do I close the quickfix 'window'? How do I get it to check for errors after I've made changes to my code? I've looked at the vim quickfix docs but the amount of commands are overwhelming and I can't seem to find what I want. Any help would be appreciated. A side question: is there any way to have javascriptlint check for js errors for code residing in a .html file? Thanks!

• ASP.NET aspxerrorpath in URL

  - by theog

  I have a site where I use CustomErrors in the web.config to specify a custom error page, and that's working just fine. The custom 404 page is also specified in the IIS configuration (because if it's not, I don't get my custom 404 page). But I have some logic that kicks in if a user gets a 404 that looks at their requested URL and make a navigation suggestion, if appropriate. This logic relies on the aspxerrorpath value. On my development PC, the aspxerrorpath is correctly appended to the URL, like so: http://localhost:3092/FileNotFound.aspx?aspxerrorpath=/badpage.aspx, but on my test site, there's no aspxerrorpath appended to the URL, so all of my custom logic is bypassed and my suggestions don't work. I'm not sure if this is an IIS config issue or something else. The web server is Windows Server 2008 with IIS 7. Any thoughts? Many Thanks.

• How to safely backport specific linux kernel commits to an older kernel using git

  - by superc0w

  I'm currently on a stable 2.6.32 kernel. But I need certain fixes on 2.6.33 branch to be incorporated into this 2.6.32 kernel so that I can create a custom kernel for testing purposes. I can't apply the said fixes directly to the 2.6.32 source because they seem to have dependencies on other fixes. Is there any safe way to incorporate only the fixes (and all their dependencies) I need into the 2.6.32 kernel with git to create a custom kernel? Assuming there is a way to do the above, is there a way to track the fixes that have been applied to the custom kernel (i.e. track which commits have been applied to the 2.6.32 kernel to create the custom kernel source)?

• Silverlight error-handling conventions: There is no relationship between onSilverlightError and Repo

  - by rasx

  When I see the call System.Windows.Browser.HtmlPage.Window.Eval (which is evil) in ReportErrorToDOM (in App.xaml.cs) this shows me that it has no relationship to onSilverlightError. So what kind of JavaScript-based scenario calls onSilverlightError? When will onSilverlightError definitely be needed? What are Silverlight error-handling conventions in general? This is a very important comment by Erik Monk but needs more detail: There are 2 kinds of terminal errors in Silverlight. 1) Managed errors (hit the managed Application_UnhandledException method). Note that some errors may not even get to this point. If the managed infrastructure can't be loaded for some reason (out of memory error maybe...), you won't get this kind of error. Still, if you can get it, you can use a web service (or the CLOG project) to communicate it back to the server. 2) Javascript errors.

• Getting 500 Error when trying to access Rails application through Apache2

• Exception Class: When to Derive from it, In C# (.Net)?

  - by IbrarMumtaz

  I am continuing with my exam revision. I have come across the usage of the Base Exception class and I have seen it on exam papers also. My question is when do you derive from the Base Exception class? I am of the impression if you want a custom class to throw an exception with more meaningful information, then you can create a custom exception class that contains the exact data that is representative of how your custom class is used and what scenario it is designed to be used for? Why can't my custom exception class derive from 'ApplicationException' or 'SecurityException' or the base 'Exception' class? I am of the impression that I should derive from the base Exception class and not the previous two. My question second is, when would you derive from the other two??? Are there any clear-cut distinctions as to when you would derive from either one of these three? Assuming there are no others I have I have missed out? Thanks, Ibrar

The problem we are facing is that a lot of the headers are included with absolute paths in the Linux format such as: #include /path/to/custom/header.h What I would like to be able to do is have Eclipse CDT map /path/to/custom/ to C:\path\to\custom.

• How to access SharePoint web part properties?

  - by shannon.stewart

  I have created a feature for SharePoint 2007 that has a web part. I have added a custom property to the web part like so: [Personalizable(PersonalizationScope.Shared)] [WebBrowsable(true)] [Category("My Custom Properties")] [WebDisplayName("ServiceURL")] [WebDescription("The URL for the Wcf service")] public string ServiceURL { get; set; } Along with this web part, I've added a custom page that the web part will have a link to. I would like to reference the web part property from the custom page, but I don't know where these properties are stored. I've tried to access it using the code below, but both property collections don't have any properties stored. SPFeaturePropertyCollection spProperties = SPContext.Current.Site.Features[this.FeatureGuid].Properties; or SPFeaturePropertyCollection spProperties = SPContext.Current.Site.Features[this.FeatureGuid].Definition.Properties; My question is how can I get a reference to the web part property from other pages?

• Paypal IPN Confirmation Screen immediately after redirect without reload

  - by Email

  Hi I made a script for IPN which works great but how can i immediately notify the user? I mean paypal redirects the customer to a custom-page i can define, simultanously my ipn.php checked the status, BUT how can i immediately tell the customer on this custom-page that it was successful or not. this custom-page does somehow has to know that this is the customer-xyz which made the ipn-verified!!! payment xyz, but how? i think also this custom-page redirect should wait the 5 seconds because php does only process files/request on-loads... so after 5 seconds the ipnscript surely did complete. Sorry if this question is too newby but i dont know how to notify the customer about the (ipn-verified!!!) payment-status immediately. How do you do this? Thanks so much

• Ruby on Rails bizarre behavior with ActiveRecord error handling

  - by randombits

  Can anyone explain why this happens? mybox:$ ruby script/console Loading development environment (Rails 2.3.5) >> foo = Foo.new => #<Foo id: nil, customer_id: nil, created_at: nil, updated_at: nil> >> bar = Bar.new => #<Bar id: nil, bundle_id: nil, alias: nil, real: nil, active: true, list_type: 0, body_record_active: false, created_at: nil, updated_at: nil> >> bar.save => false >> bar.errors.each_full { |msg| puts msg } Real can't be blank Real You must supply a valid email => ["Real can't be blank", "Real You must supply a valid email"] So far that is perfect, that is what i want the error message to read. Now for more: >> foo.bars << bar => [#<Bar id: nil, bundle_id: nil, alias: nil, real: nil, active: true, list_type: 0, body_record_active: false, created_at: nil, updated_at: nil>] >> foo.save => false >> foo.errors.to_xml => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<errors>\n <error>Bars is invalid</error>\n</errors>\n" That is what I can't figure out. Why am I getting Bars is invalid versus the error messages displayed above, ["Real can't be blank", "Real you must supply a valid email"] etc. My controller simply has a respond_to method with the following in it: format.xml { render :xml => @foo.errors, :status => :unprocessable_entity } How do I have this output the real error messages so the user has some insight into what they did wrong?

• undefined returned for currentView object in Backbone.Marionette

  - by ontk

  I am testing how a layout can listen to its subviews's custom events. I created a jsFiddle here where I have a layout, 2 regions and I instantiated 2 ItemViews and showed them in the layout's regions. The fiddle is in CoffeeScript. <div id="region"></div> <script id="layout-tmpl" type="text/_"> <h3>Heading</h3> <div id="content"></div> <div id="content2"></div> </script> <script id="item-tmpl" type="text/_"> <form> <label>Firstname:</lable> <input type="text" name="firstname" value="<%= firstname %>" /> <input type="button" value="Save" id="save" /> </form> </script> And the CoffeeScript is: SimpleLayout = Backbone.Marionette.Layout.extend template: '#layout-tmpl' regions: main: '#content' other: '#content2' initialize: () -> console.log @ onShow: () -> _.each @.regionManagers, (region, name, something) => console.log region.currentView # @.bindTo region.currentView, "custom:event", @callback callback: () -> alert "HELL YEAH" SimpleItemView = Backbone.Marionette.ItemView.extend template: "#item-tmpl" events: 'click #save': 'save' save: (evt) -> evt.preventDefault() @.trigger "custom:event" region = new Backbone.Marionette.Region el: "#region" layout = new SimpleLayout() region.show layout layout.main.show new SimpleItemView model: (new Backbone.Model firstname: "Olivier") layout.other.show new SimpleItemView model: (new Backbone.Model firstname: "Travis") I want the layout to listen to the ItemViews's custom events. In the onShow, I am looping through the region managers and trying to access the currentView object but it returns undefined. If I attach the same event handlers outside of the SimpleLayout class and after I show the itemviews, then the layout handlers the custom events properly. Thanks for your help.

• Why C# IntelliSense is delayed compared to VB.NET?

  - by Sphynx

  In VB.NET projects, errors are highlighted immediately after cursor leaves the line. IN C#, I have to wait several seconds for IntelliSense to highlight it. Also, C# version doesn't show all project errors in "Errors List", unless you start to build it. Actually, it seems to work differently in every way. Is it possible to adjust that behavior?

• Using MembershipCreateStatus in MVC

  - by Jemes

  How can I use the MembershipCreateStatus in my controller below to identify errors? My controller below creates a new user but I would like to catch any errors from CreateStatus and add the error to my modelstate. [HttpPost] public ActionResult CreateUser(user UserToCreate) { if (ModelState.IsValid) { // TODO: If the UserToCreate object is Valid we'll //Eventually want to save it in a database Membership.CreateUser(UserToCreate.Username, UserToCreate.Password, UserToCreate.Email); return Redirect("/"); } //Invalid - redisplay form with errors return View(UserToCreate); }

• Only variables can be passed by reference

  - by zaf

  I had the bright idea of using a custom error handler which led me down a rabbit hole. Following code gives (with and without custom error handler): Fatal error: Only variables can be passed by reference function foo(){ $b=array_pop(array("a","b","c")); return $b; } print_r(foo()); Following code gives (only with a custom error handler): (2048) Only variables should be passed by reference function foo(){ $a=explode( '/' , 'a/b/c'); $c=array_pop(array_slice($a,-2,1)); return $c; } print_r(foo()); The second one worries me since I have a lot of 'compact' code. So, I either ditch the bright idea of using a custom error handler (to improve my logging module) or expand all my code. Anyone with better ideas? Also, WTF?

• Where is the appropriate place to define inflector rules in CakePHP 1.3?

  - by Daniel Wright

  In CakePHP 1.2, custom inflector rules could be defined in a file app/config/inflections.php. This file was removed in CakePHP 1.3. Instead, the documentation prescribes using the Inflector::rules function to load custom inflections. There's adequate documentation of how to define the custom inflections themselves, but the documentation gives no context—where to use Inflector::rules. Should any custom inflections be defined in the bootstrap.php script? At the top of applicable corresponding controllers? Somewhere else? See also: Configuration: Inflections in the documentation Inflector::rules definition in the API documentation
