25,107,717 | 0 | <p>I just encountered this issue in CE v1.9.0.1. My admin module was getting all processes as a collection and looping through each one calling reindexEverything(). I based the code on the adminhtml process controller which was working fine, but my code wasn't working at all.</p> <p>I finally figured out the issue was that I had previously set the reindex mode to manual (to speed up my product import routine) as follows:</p> <pre><code>$processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_MANUAL)); // run product import $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); foreach($processes as $p) { if($p->getIndexer()->isVisible()) { $p->reindexEverything(); //echo $p->getIndexer()->getName() . ' reindexed<br>'; } } $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_REAL_TIME)); </code></pre> <p>SOLUTION: set mode back to MODE_REAL_TIME before reindexing everything:</p> <pre><code>$processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_MANUAL)); // run product import $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_REAL_TIME)); $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); foreach($processes as $p) { if($p->getIndexer()->isVisible()) { $p->reindexEverything(); //echo $p->getIndexer()->getName() . ' reindexed<br>'; } } </code></pre> <p>Note: these are snips from a few different methods hence the repeated assignment of $processes etc..</p> <p>It seemed reindexEverything() wasn't doing anything when the processes index mode was set to MODE_MANUAL. Setting mode back to MODE_REAL_TIME and then calling reindexEverything worked fine.</p> <p>I hope this helps someone as I had a few frustrated hours figuring this one out!</p> <p>Thanks</p> |
931,767 | 0 | <h2>Binary Trees</h2> <p>There exists two main types of binary trees, balanced and unbalanced. A balanced tree aims to keep the height of the tree (height = the amount of nodes between the root and the furthest child) as even as possible. There are several types of algorithms for balanced trees, the two most famous being AVL- and RedBlack-trees. The complexity for insert/delete/search operations on both AVL and RedBlack trees is <strong><em>O(log n)</em></strong> or <strong>better</strong> - which is the important part. Other self balancing algorithms are AA-, Splay- and Scapegoat-tree.</p> <p>Balanced trees gain their property (and name) of being balanced from the fact that after every delete or insert operation on the tree the algorithm introspects the tree to make sure it's still balanced, if it's not it will try to fix this (which is done differently with each algorithm) by rotating nodes around in the tree.</p> <p>Normal (or unbalanced) binary trees do not modify their structure to keep themselves balanced and have the risk of, most often overtime, to become very inefficient (especially if the values are inserted in order). However if performance is of no issue and you mainly want a sorted data structure then they might do. The complexity for insert/delete/search operations on an unbalanced tree range from O(1) (best case - if you want the root) to O(n) (worst-case if you inserted all nodes in order and want the largest node)</p> <p>There exists another variation which is called a randomized binary tree which uses some kind of randomization to make sure the tree doesn't become fully unbalanced (which is the same as a linked list)</p> |

8,023,571 | 0 | What's wrong with this QuickSort program? <p>I've written a QuickSort algorithm based off pseudo-code that I had been given. I've been running through the outputs for about 4 hours now and I can't seem to find exactly why my algorithm starts to derail. This sort of collection logic is something I struggle with.</p> <p>Anyway, whenever I run my program there's 3 possible results:</p> <ol> <li>The list is organized and is 100% correct.</li> <li>The list is 90% organized, one or two pairs of elements are off.</li> <li>The list is never sorted and results in an infinite loop.</li> </ol> <p>Given my results it leads me to believe that something has to do with the <code>index</code> variable I'm using. However, I can' figure out why or what's wrong with it.</p> <p>Here's ALL of my code that I use for my QuickSort algorithm:</p> <pre><code>public void QuickSort(IList<int> list, int l, int r) { if (l>=r) return; int index = Partition(list, l, r); Console.WriteLine("index: " + index); QuickSort(list, l, (index-1)); QuickSort(list, (index+1), r); } public int Partition(IList<int> list, int l, int r) { int pivot = list[l]; int i = l; int j = r + 1; do { do { i++; } while(i < list.Count && list[i] < pivot); do { j--; } while(j > 0 && list[j] >= pivot); Swap(list, i, j); } while(i<j); Swap(list, i ,j); Swap(list, j, l); return j; } public void Swap(IList<int> list, int i, int j) { //Console.WriteLine("Swapping [i] " + list[i] + " with [j] " + list[j]); //PrintList(list, i, j, false); int temp = list[i]; list[i] = list[j]; list[j] = temp; //PrintList(list, j, i, true); } </code></pre> <p>PrintList is simply used to test my outputs.</p> <p>Here is a sample input/output:</p> <p>INPUT: [18,43,5,73,59,64,6,17,56,63]</p> <p>OUTPUT: [5,6,18,17,43,59,56,63,64,73]</p> |

5,177,191 | 0 | <p><em>(I realise this question is old, but it's something that other people might want an answer to)</em></p> <p>BASIC Authentication doesn't really allow what you're asking for, but you can get something that works a bit like what you want, if you're willing to live with some "quirks".</p> <p>BASIC Authentication has 2 aspects that make it hard to control in this way</p> <ul> <li>It is stateless</li> <li>It is client-side</li> </ul> <p>Both of those aspects are features, but they make it hard to link BASIC authentication to Java sessions. That is why alternate login mechanisms (like Java FORM login exist)</p> <p><strong>BASIC Authentication is stateless</strong><br> That means that the client has absolutely no idea what is going on on the server-side, and it certainly has no way of linking a set of BASIC Authentication credentials to a cookie (which is what mostly controls the java session)<br> What happens in that the browser will simply send the username+password with <em>every</em> request, until it decides to stop (generally because the browser was closed, and a new browser session was created).<br> The browser doesn't know what the server is doing with the credentials. It doesn't know whether they're needed any more, or not, and it doesn't know when the server side has decided that a "new session" has started, it just keeps on sending that username+password with each request.</p> <p><strong>BASIC Authentication is Client-Side</strong><br> That dialog for the user/password is handled by the client. All the server says is "The URL you requested needs a username+password, and we've named this security realm 'xyz' ".<br> The server doesn't know whether the user is typing in a password each time, or whether the client has cached them. It doesn't know if there really is a user there, or whether the password was pulled out of a file.<br> The only thing the server can do is say "You need to give me a user+password before accessing this URL"</p> <p><strong>How to fake it</strong><br> Essentially, you need to detect (i.e. make an educated guess) when the browser is sending old credentials and then send the "Please give me a user+password" response (HTTP 401) again.</p> <p>The simplest way to do that is to have a filter in your application that detects the first time the user has logged in for that session, and sends a <code>401</code> response code. Something like:</p> <pre><code> if(session.getAttribute("auth") == null) { response.setStatus(401); response.setHeader("WWW-Authenticate", "basic realm=\"Auth (" + session.getCreationTime() + ")\"" ); session.setAttribute("auth", Boolean.TRUE); writer.println("Login Required"); return; } </code></pre> <p>In that example I've named the realm with the creation time of the session (although it's not very pretty - you'd probably want to format it differently). That means that the name of the security realm changes each time you invalidate the session, which helps prevent the client from getting confused (why is it asking me for a user+password again, for the same realm, when I just gave one?).<br> The new realm name will not confuse the servlet container, because it will never see it - the client response does not include the realm name.</p> <p>The trick though, it that you don't want the user to get asked for their password twice the first time they logon. And, out of the box, this solution will do that - once for the container to ask for it, and then again when your filter does.</p> <p><strong>How to avoid getting 2 login boxes</strong> There are 4 options.</p> <ol> <li>Do it all in code.</li> <li>Use a secondary session cookie to try and tell whether the user is logging in for the first time. </li> <li>Have your root URL be unsecured (but have it do nothing)</li> <li>Have all your app be unsecured, except for 1 page, and redirect users to that page if they are not logged in.</li> </ol> <p><strong>Do it in code</strong></p> <p>If you're happy to do all of the security inside your own servlet/filter, and get no help from the servlet container (Jetty) then that's not too hard. You simply turn off BASIC auth in your web.xml, and do it all in code. (There's a fair bit of work, and you need to make sure you don't leave any security holes open, but it's conceptually quite easy)<br> Most people don't want to do that.</p> <p><strong>Secondary Cookies</strong><br> After a user logins in to your application, you can set a cookie ("authenticated") that expires at the end of the browser session. This cookie is tied to the browser session and <strong>not</strong> to the Java session.<br> When you invalidate the Java session - <em>do not</em> invalidate the <em>"authenticated"</em> cookie.<br> If a user logs in to a <em>fresh</em> java session (i.e. <code>session.getAttribute("auth")==null</code>), but still has this <em>"authenticated"</em> then you know that they're re-using an existing browser session and are <em>probably</em> re-using existing HTTP authentication credentials. In that case you do the <code>401</code> trick to force them to give new credentials.</p> <p><strong>Unsecured root URL</strong><br> If your root URL is unsecured, and you know that this is the URL that your users always login to, then you can simply put your "auth"/<code>401</code> check at that URL, and it will solve the problem. But make sure you don't accidentally open a security hole.<br> This URL should not have any functionality other than redirecting users to the "real" app (that is secured)</p> <p><strong>Single secured URL</strong><br> Have 1 URL that is secured (e.g. "/login").<br> As well as your "auth"/<code>401</code> filter, have another filter (or additional code in the same filter) on all pages (other than login) that checks whether <code>request.getUserPrincipal()</code> is set. If not, redirect the user to "/login".</p> <p><strong>The <em>much</em> easier solution</strong><br> Just use a FORM login method instead of BASIC authentication. It's designed to solve this problem.</p> |

25,276,484 | 0 | <p>Your performance is pretty good. Your problem is that you're being abused by, what sounds like poor coding, in the sproc you mentioned. So, let's say you manage to improve the performance of your query by 90% and soon after the sproc starts calling your query 20,000 times... you're back where you started. </p> <p>I would begin by investigating the problem sproc to see if there's a better solution than thousands of calls in a short period of time. Could be a simple fix of not calling a query from a loop, as a simple example. The client code could also use caching instead of calling a query repeatedly for data that doesn't change much.</p> <p>If you want to follow the performance route then I would suggest denormalizing. Since your query results are boxed by week, denormalizing is actually a good solution. You would create another table and populate it with results from your query... You would also not be calling tour subqueries all the time. SQL Server usually optimizes for that but it's definitely something worth trying. </p> <p>Good luck. </p> |

11,517,151 | 0 | How to manually install .Net 4.0.x and 4.5 on XP <p>XP isn't a supported OS for .NET 4.5. This is a known issue.</p> <p>I read a few months back that the reason XP can't install 4.5 is because there are kernel API that 4.5 calls which don't exist on XP. I also read that it would be possible to inject your own implementation of the 'new' kernel calls to an XP machine - and 4.5 <em>could</em> run.</p> <p>I can no longer find this information. Does anyone know more about this?</p> <p>A second, but related, question is - how can I take upgraded .Net 4.0 libraries from a windows 7 machine (which had 4.5 installed) and inject them into an xp machine? I believe I read that the implemention files of 4.5 are actually the same as the 4.0 files, there are not two sets. And in fact, the two .net folders (4.0 and 4.5) are only the interfaces - which link back to these same files. If this is the case, then a manual injection of the 4.0 files would likely need the solution to my first question.</p> <p>In short - does anyone have more information about hacking/manually upgraded .net for xp?</p> |

If the upgrades are don in-place (keeping the machine name the same and preserving the SSB endpoint settings) then you won't have to change anything after the upgrade, it should just keep working.</p> <p>If you do side-by-side upgrade then you will have to port the SSB endpoint settings and certificates used from one instance to the other, along with moving the database.</p> <p>Keep in mind that if you have a problem and you are forced to rollback to a backup then your entire, distributed, system state will not be consistent (basically conversations will no longer match the send sequence number and receive sequence numbers) and you may have to force some close conversations (manual END ... WITH CLEANUP on a case by case) or nuke the entire broker in the DB (ALTER DATABASE ... SET NEW_BROKER). Lets hope you won't have to do this. If is feasible then you could simply stop the entire system (eg. run ALTER ENDPOINT ...

31,193,716 | 0 | UITabBarController - transition from one tab's navigation stack to a view controller of another tab's navigation stack <p>Novice iOS developer here. I am making a simple tabbed chat application in Swift using a UITabBarController. For simplicity, let's assume the application only has two tabs, "Contacts" and "Chats". Each of the two tabs has a navigation controller. </p> <p>The "Chats" navigation stack begins with a UITableViewController called "ChatsTableViewController" which lists the user's chats. When the user selects a chat, the app segues to a MessagesViewController which displays the messages for the selected chat.</p> <p>The "Contacts" navigation stack includes a UITableViewController which lists the user's contacts. Upon selecting a contact, another view controller is presented modally, asking the user whether they would like to begin a chat with the selected contact, and giving them the option to cancel. If the user chooses to begin a chat, I would like to transition from this modal view controller to the MessagesViewController of the "Chats" tab, passing the information necessary to display the chat (which I have at the ready in the modal view controller).</p> <p>When the MessagesViewController loads, regardless of whether we get to it by selecting a chat from the "Chats" tab or by creating a new chat from the "Contacts" tab, it should have a navigation bar at the top with a "Back" button that takes the user to the ChatsTableViewController.</p> <p>I have done a good deal of searching, but have not found any solutions that fit what I need. Any suggestions would be greatly appreciated! Here is a summary of what I am looking for.</p> <ol> <li>Standard way to perform a transition from a view controller in one tab's navigation stack to a view controller (that is not the root view controller in my case) of another tab's navigation stack, while passing relevant information to display in the destination view controller.</li> <li>The view controller I transition to should have a navigation bar with a back button that takes the user to the previous view controller in its navigation stack, just as if they had accessed it from the normal navigation flow of the tab.</li> </ol> <p><strong>EDIT</strong>: I've found that you can easily switch tabs programmatically using <code>self.tabBarController?.selectedIndex = index_of_tab_to_switch_to</code>, however, this takes me to the first view of the tab and I am still unsure of how I can pass data.

1,255,891 | 0 | <p>Maybe it won't be a full answer to your question, but here's what I've been able to find so far : there is some kind of a partial answer in the book "<strong>Extending and Embedding PHP</strong>", written by Sara Golemon (<a href="http://rads.stackoverflow.com/amzn/click/067232704X" rel="nofollow noreferrer">amazon</a> ; some parts are also available on google books).</p> <p>The relevant part <em>(a note at the top of page 56)</em> is :</p> <blockquote> <p>Ever wonder why some extensions are configured using <code>--enable-extname</code> and some are configured using <code>--with-extename</code>? Functionnaly, there is no difference between the two. In practice, however, <code>--enable</code> is meant for features that can be turned on witout requiring any third-party libraries. <code>--with</code>, by contrast, is meant for features that do have such prerequisites.</p> </blockquote> <p>So, not a single word about performance (I guess, if there is a difference, it is only a matter of "<em>loading one more file</em>" vs "<em>loading one bigger file</em>") ; but there is a technical reason behind this possibility.</p> <p>I guess this is done so PHP itself doesn't <strong>require</strong> an additionnal external library because of some extension ; using the right option allows for users to enable or disable the extension themselves, depending on whether or not they already have that external library.</p> |
29,879,976 | 0 | <p>I had the same problem and i was already applying the Judah answer before i found this topic after some googling. </p> <p>Well, imo the Judah answer is partially correct. I found a better answer <a href="https://social.msdn.microsoft.com/Forums/en-US/751637d8-2c98-49d1-a4d3-9bc0ef0996c1/runworkercompleted-not-capturing-exceptions?forum=csharplanguage" rel="nofollow">here</a></p> <p>The debugger is making the work well, if you run the application in "real-world conditions", the RunWorkerCompleted deals with the exception as expected and the application behavior is also the expected.</p> <p>I hope this answer helps.</p> |
15,249,497 | 0 | <p>selectedRow is populated after you click the row, while you are trying to loop trough it after binding the click handler, but before the actual click. You have to move that code in the click handler</p> |
4,471,371 | 0 | <p>This has nothing to do with calling revalidate as recommended by another and likely has all to do with calling a method on the wrong object. In your showEmployeesActionPerformed method you create a new Company object, one that is not visualized. The key is to call this method on the proper reference, on the visualized GUI. You do this by passing a reference to the visualized GUI object into the class that is wanting to call methods on it. This can be done via a setCompany method:</p> <pre><code>setCompany(Company company) { this.company = company); } </code></pre> <p>or via a constructor parameter.</p> |

10,545,891 | 0 | <p>It appears that you are using this database migration solely for populating the data. </p> <p>Database migrations are meant for changing the database schema, not for populating the database (though you can add some logic to populate the database after the change; for example, if you add a column - role to users table, you can add some custom logic to populate the newly added field for existing entries in users table). Refer to rails api - <a href="http://guides.rubyonrails.org/migrations.html" rel="nofollow">migrations</a> for details. </p> <p>If you forgot add the code to populate the database in your previous database migration, you can undo the previous migration and apply it again using: </p> <pre><code>rake db:rollback ... Edit the previous migration ..Add the code to populate rake db:migrate </code></pre> <p>If you just want to populate the database, you should seed the database instead. Watch <a href="http://railscasts.com/episodes/179-seed-data" rel="nofollow">this railscast</a> for more information.</p> <p>EDIT: To seed the database: </p> <p>Create a file called db/seeds.rb<br> Add the record creation code like this: </p> <pre><code>['Sampath', 'Suresh'].each do |name| User.create(role: 'admin', username: name) end </code></pre> <p>Then, </p> <pre><code>rake db:seed </code></pre> <p>This will read the seeds.rb and populate the database.</p> |
31,613,860 | 0 | <p>What's wrong with a <code>500 Internal Server Error</code>?! That's exactly what you experience. Your script is wrong and dies a sudden death; that's an internal error in your server. A <code>500</code> response signals to the client that there was an error which is not the fault of the client, so the client should not use whatever response it received and maybe try again later. That's exactly what must happen in this scenario and that's what <code>display_errors=off</code> does.</p> |

4,110,181 | 0 | <p>I don't understand your concern about G, H, I appearing on branchB instead of branchA. What I mean is, if you rename your <code>branchA</code> to <code>branchB</code>, and branch off from <code>I</code> to create the new <code>branchA</code>, and commit <code>M</code> to <code>branchA</code>, you should get what you want.</p> <p>As far as I know, the branches are simply named heads pointing to particular commits (look at .git/refs/heads), and the rest of the tree is determined solely by parent-child relationships in git. Even if you somehow manage to rebase J-K-L onto a new branchB, and commit M to the now vacant space, the object data would be identical. Both M and J would point at I as their parents, and G/D would point to C as their parents, and the rest would simply point to their immediate parent. Am I missing something here?</p> |

Then i created a branch B, from branch A. Both branches are evolving concurrently. </p> <p>At some point i cherry-picked some revisions from branch B into trunk to get some features developed in branch B.</p> <p>Now, i synced branch A with trunk:</p> <pre><code>~/branch_a$ svn merge ^/trunk ~/branch_a$ svn commit </code></pre> <p>No problems here. Next step is to sync B with A:</p> <pre><code>~/branch_b$ svn merge ^/trunk </code></pre> <p>Here i get some tree conflicts, in files/dirs that already existed in trunk before the merge but were changed in the cherry-picks i did earlier (don't know if it has anything to do with it, i'm just mentioning it):</p> <pre><code> C some_dir/other_dir/some_file.php > local add, incoming add upon merge C some_other_dir/some_sub_dir > local add, incoming add upon merge </code></pre> <p>Essentially i want the versions of the files that are coming in from the merge and discard the current version. What's the best way to solve this?</p> <p>Thanks in advance!</p> |
