• Cisco ASA: How to route PPPoE-assigned subnet?

  - by Martijn Heemels

  We've just received a fiber uplink, and I'm trying to configure our Cisco ASA 5505 to properly use it. The provider requires us to connect via PPPoE, and I managed to configure the ASA as a PPPoE client and establish a connection. The ASA is assigned an IP address by PPPoE, and I can ping out from the ASA to the internet, but I should have access to an entire /28 subnet. I can't figure out how to get that subnet configured on the ASA, so that I can route or NAT the available public addresses to various internal hosts. My assigned range is: 188.xx.xx.176/28 The address I get via PPPoE is 188.xx.xx.177/32, which according to our provider is our Default Gateway address. They claim the subnet is correctly routed to us on their side. How does the ASA know which range it is responsible for on the Fiber interface? How do I use the addresses from my range? To clarify my config; The ASA is currently configured to default-route to our ADSL uplink on port Ethernet0/0 (interface vlan2, nicknamed Outside). The fiber is connected to port Ethernet0/2 (interface vlan50, nicknamed Fiber) so I can configure and test it before making it the default route. Once I'm clear on how to set it all up, I'll fully replace the Outside interface with Fiber. My config (rather long): : Saved : ASA Version 8.3(2)4 ! hostname gw domain-name example.com enable password ****** encrypted passwd ****** encrypted names name 10.10.1.0 Inside-dhcp-network description Desktops and clients that receive their IP via DHCP name 10.10.0.208 svn.example.com description Subversion server name 10.10.0.205 marvin.example.com description LAMP development server name 10.10.0.206 dns.example.com description DNS, DHCP, NTP !

• Clustered MSDTC

  - by niel

  Hi I'm setting up a SQL cluster (SQL 2008), Windows 2008 R2. I enable the network access on local dtc and then create a DTC resource in my cluster . the problem is that when i start up the resource it does nto pull through my settings to enable network access. the log shows this: MSDTC started with the following settings: Security Configuration (OFF = 0 and ON = 1): Allow Remote Administrator = 0, Network Clients = 0, Trasaction Manager Communication: Allow Inbound Transactions = 0, Allow Outbound Transactions = 0, Transaction Internet Protocol (TIP) = 0, Enable XA Transactions = 0, Enable SNA LU 6.2 Transactions = 1, MSDTC Communications Security = Mutual Authentication Required, Account = NT AUTHORITY\NetworkService, Firewall Exclusion Detected = 0 Transaction Bridge Installed = 0 Filtering Duplicate Events = 1 where when i restart the local dtc service it says this: Security Configuration (OFF = 0 and ON = 1): Allow Remote Administrator = 0, Network Clients = 1, Trasaction Manager Communication: Allow Inbound Transactions = 1, Allow Outbound Transactions = 1, Transaction Internet Protocol (TIP) = 0, Enable XA Transactions = 1, Enable SNA LU 6.2 Transactions = 1, MSDTC Communications Security = No Authentication Required, Account = NT AUTHORITY\NetworkService, Firewall Exclusion Detected = 0 Transaction Bridge Installed = 0 Filtering Duplicate Events = 1 settings on both nodes in teh cluster is the same. I have reinstalled and restarted to many times to mention. Any ideas ?

• Add new item to UITableView and Core Data as data source?

  - by David.Chu.ca

  I have trouble to add new item to my table view with core data. Here is the brief logic in my codes. In my ViewController class, I have a button to trigle the edit mode: - (void) toggleEditing { UITableView *tv = (UITableView *)self.view; if (isEdit) // class level flag for editing { self.newEntity = [NSEntityDescription insertNewObjectForEntityName:@"entity1" inManagedObjectContext:managedObjectContext]; NSArray *insertIndexPaths = [NSArray arrayWithObjects: [NSInextPath indexPathForRow:0 inSection:0], nil]; // empty at beginning so hard code numbers here. [tv insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationFade]; [self.tableView setEditing:YES animated:YES]; // enable editing mode } else { ...} } In this block of codes, I added a new item to my current managed object context first, and then I added a new row to my tv. I think that both the number of objects in my data source or context and the number of rows in my table view should be 1. However, I got an exception in the event of tabView:numberOfRowsInSection: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (0) must be equal to the number of rows contained in that section before the update (0), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted). The exception was raised right after the delegate event: - (NSInteger) tableView:(UITableView *) tableView numberOfRawsInSection:(NSInteger) section { // fetchedResultsController is class member var NSFetchedResultsController id <NSFechedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex: section]; NSInteger rows = [sectionInfo numberOfObjects]; return rows; } In debug mode, I found that the rows was still 0 and the event invoked after the the even of toggleEditing. It looks like that sectionInfo obtained from fetchedResultsController did not include the new entity object inserted. Not sure if I miss anything or steps? I am not sure how it works: to get the fetcedResultsController notified or reflect the change when a new entity is inserted into the current managed object context?

• How can I add an additional site to my VPS server?

  - by user482594

  I have a VPS hosting service. First of all, I installed bind9 and everything that my main website works just fine. Now, I bought another domain and set its nameserver address&ip to my website ones. I added a configuration file of that site like '/etc/apache2/sites-available/www.example.com' and I did 'a2ensite www.example.com' to enable the website to apache2. After one, when I reloaded my server, I see '000default' and 'www.example.com' in my '/etc/apache2/sites-enabled/' directory. I have thought I am done with settings, but I still cannot connect to the domain example.com. I think I have read it somewhere that I have to set up 'zone' thing which I did when I was setting dns. For example, zone "example.com" IN { type master; file "example.zone"; allow-update { none; }; }; Is this correct? If so, what are the things that I need to do afteron?

• The type 'XXX' is defined in an assembly that is not referenced exception after upgrade to ASP.NET 4

  - by imran_ku07

     Introduction :          I found two posts in ASP.NET MVC forums complaining that they are getting exception, The type XXX is defined in an assembly that is not referenced, after upgrading thier application into Visual Studio 2010 and .NET Framework 4.0 at here and here .   Description :           The reason why they are getting the above exception is the use of new clean web.config without referencing the assemblies which were presents in ASP.NET 3.5 web.config. The quick solution for this problem is to add the old assemblies in new web.config.          <assemblies>             <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>             <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>             <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>              <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />              <add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, publicKeyToken=b77a5c561934e089" />          </assemblies>    How It works :            Currently i have not tested the above scenario in ASP.NET 4.0 because i have not yet get it. But the above scenario can easily be tested and verified in VS 2008. Just Open the root web.config and remove           <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>             Even you add the reference of System.Core in your project, you will still get the above exception because aspx pages are compiled in separate assembly. You can check this yourself by checking Show Detailed Compiler Output: below in the yellow screen of death, you will find something,/out:"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\root\e907aee4\5fa0acc8\App_Web_y5rd6bdg.dll"             This shows that aspx pages are compiled in separate assembly in Temporary ASP.NET Files.Summary :             After getting the above exception make sure to add the assemblies in web.config or add the Assembly directive at Page level. Hopefully this will helps to solve your problem.

• Add options to select box without Internet Explorer closing the box?

  - by Paul Colby

  Hi, I'm trying to build a web page with a number of drop-down select boxes that load their options asynchronously when the box is first opened. This works very well under Firefox, but not under Internet Explorer. Below is a small example of what I'm trying to achieve. Basically, there is a select box (with the id "selectBox"), which contains just one option ("Any"). Then there is an onmousedown handler that loads the other options when the box is clicked. <html> <head> <script type="text/javascript"> function appendOption(select,option) { try { selectBox.add(option,null); // Standards compliant. } catch (e) { selectBox.add(option); // IE only version. } } function loadOptions() { // Simulate an AJAX request that will call the // loadOptionsCallback function after 500ms. setTimeout(loadOptionsCallback,500); } function loadOptionsCallback() { var selectBox = document.getElementById('selectBox'); var option = document.createElement('option'); option.text = 'new option'; appendOption(selectBox,option); } </script> </head> <body> <select id="selectBox" onmousedown="loadOptions();"> <option>Any</option> </select> </body> </html> The desired behavior (which Firefox does) is: the user see's a closed select box containing "Any". the user clicks on the select box. the select box opens to reveal the one and only option ("Any"). 500ms later (or when the AJAX call has returned) the dropped-down list expands to include the new options (hard coded to 'new option' in this example). So that's exactly what Firefox does, which is great. However, in Internet Explorer, as soon as the new option is added in "4" the browser closes the select box. The select box does contain the correct options, but the box is closed, requiring the user to click to re-open it. So, does anyone have any suggestions for how I can load the select control's options asynchronously without IE closing the drop-down box? I know that I can load the list before the box is even clicked, but the real form I'm developing contains many such select boxes, which are all interrelated, so it will be much better for both the client and server if I can load each set of options only when needed. Also, if the results are loaded synchronously, before the select box's onmousedown handler completes, then IE will show the full list as expected - however, synchronous loading is a bad idea here, since it will completely "lock" the browser while the network requests are taking place. Finally, I've also tried using IE's click() method to open the select box once the new options have been added, but that does not re-open the select box. Any ideas or suggestions would be really appreciated!! :) Thanks! Paul.

  I have a jqGrid multiple search dialog as below: (Note the first empty td in each row). What I want is a search grid like this (below), where: The first td is filled in with "and/or" accordingly. The corresponding search filters are also built that way. The empty td is there by default, so I assume that this is a standard jqGrid feature that I can turn on, but I can't seem to find it in the docs. My code looks like this: <script type="text/javascript"> $(document).ready(function () { var lastSel; var pageSize = 10; // the initial pageSize $("#grid").jqGrid({ url: '/Ajax/GetJqGridActivities', editurl: '/Ajax/UpdateJqGridActivities', datatype: "json", colNames: [ 'Id', 'Description', 'Progress', 'Actual Start', 'Actual End', 'Status', 'Scheduled Start', 'Scheduled End' ], colModel: [ { name: 'Id', index: 'Id', searchoptions: { sopt: ['eq', 'ne']} }, { name: 'Description', index: 'Description', searchoptions: { sopt: ['eq', 'ne']} }, { name: 'Progress', index: 'Progress', editable: true, searchoptions: { sopt: ['eq', 'ne', "gt", "ge", "lt", "le"]} }, { name: 'ActualStart', index: 'ActualStart', editable: true, searchoptions: { sopt: ['eq', 'ne', "gt", "ge", "lt", "le"]} }, { name: 'ActualEnd', index: 'ActualEnd', editable: true, searchoptions: { sopt: ['eq', 'ne', "gt", "ge", "lt", "le"]} }, { name: 'Status', index: 'Status.Name', editable: true, searchoptions: { sopt: ['eq', 'ne']} }, { name: 'ScheduledStart', index: 'ScheduledStart', searchoptions: { sopt: ['eq', 'ne', "gt", "ge", "lt", "le"]} }, { name: 'ScheduledEnd', index: 'ScheduledEnd', searchoptions: { sopt: ['eq', 'ne', "gt", "ge", "lt", "le"]} } ], jsonReader: { root: 'rows', id: 'Id', repeatitems: false }, rowNum: pageSize, // this is the pageSize rowList: [pageSize, 50, 100], pager: '#pager', sortname: 'Id', autowidth: true, shrinkToFit: false, viewrecords: true, sortorder: "desc", caption: "JSON Example", onSelectRow: function (id) { if (id && id !== lastSel) { $('#grid').jqGrid('restoreRow', lastSel); $('#grid').jqGrid('editRow', id, true); lastSel = id; } } }); // change the options (called via searchoptions) var updateGroupOpText = function ($form) { $('select.opsel option[value="AND"]', $form[0]).text('and'); $('select.opsel option[value="OR"]', $form[0]).text('or'); $('select.opsel', $form[0]).trigger('change'); }; // $(window).bind('resize', function() { // ("#grid").setGridWidth($(window).width()); //}).trigger('resize'); // paging bar settings (inc. buttons) // and advanced search $("#grid").jqGrid('navGrid', '#pager', { edit: true, add: false, del: false }, // buttons {}, // edit option - these are ordered params! {}, // add options {}, // del options {closeOnEscape: true, multipleSearch: true, closeAfterSearch: true, onInitializeSearch: updateGroupOpText, afterRedraw: updateGroupOpText}, // search options {} ); // TODO: work out how to use global $.ajaxSetup instead $('#grid').ajaxError(function (e, jqxhr, settings, exception) { var str = "Ajax Error!\n\n"; if (jqxhr.status === 0) { str += 'Not connect.\n Verify Network.'; } else if (jqxhr.status == 404) { str += 'Requested page not found. [404]'; } else if (jqxhr.status == 500) { str += 'Internal Server Error [500].'; } else if (exception === 'parsererror') { str += 'Requested JSON parse failed.'; } else if (exception === 'timeout') { str += 'Time out error.'; } else if (exception === 'abort') { str += 'Ajax request aborted.'; } else { str += 'Uncaught Error.\n' + jqxhr.responseText; } alert(str); }); $("#grid").jqGrid('bindKeys'); $("#grid").jqGrid('inlineNav', "#grid"); }); </script> <table id="grid"/> <div id="pager"/>

• LSI 9285-8e and Supermicro SC837E26-RJBOD1 duplicate enclosure ID and slot numbers

  - by Andy Shinn

  I am working with 2 x Supermicro SC837E26-RJBOD1 chassis connected to a single LSI 9285-8e card in a Supermicro 1U host. There are 28 drives in each chassis for a total of 56 drives in 28 RAID1 mirrors. The problem I am running in to is that there are duplicate slots for the 2 chassis (the slots list twice and only go from 0 to 27). All the drives also show the same enclosure ID (ID 36). However, MegaCLI -encinfo lists the 2 enclosures correctly (ID 36 and ID 65). My question is, why would this happen? Is there an option I am missing to use 2 enclosures effectively? This is blocking me rebuilding a drive that failed in slot 11 since I can only specify enclosure and slot as parameters to replace a drive. When I do this, it picks the wrong slot 11 (device ID 46 instead of device ID 19). Adapter #1 is the LSI 9285-8e, adapter #0 (which I removed due to space limitations) is the onboard LSI.

After getting in contact with a very knowledgeable Supermicro tech, they provided us with a tool called Xflash (doesn't appear to be readily available on their FTP). When we gathered some information using this utility, my colleague found something very strange: root@mogile2 test]# ./xflash.dat -i get avail Initializing Interface. Expander: SAS2X36 (SAS2x36) 1) SAS2X36 (SAS2x36) (50030480:00EE917F) (0.0.0.0) 2) SAS2X36 (SAS2x36) (50030480:00E9D67F) (0.0.0.0) 3) SAS2X36 (SAS2x36) (50030480:0112D97F) (0.0.0.0) This lists the connected enclosures. You see the 3 connected (we have since added a 3rd and a 4th which is not yet showing up) with their respective SAS address / WWN (50030480:00EE917F). Now we can use this address to get information on the individual enclosures: [root@mogile2 test]# ./xflash.dat -i 5003048000EE917F get exp Initializing Interface. Expander: SAS2X36 (SAS2x36) Reading the expander information..........

The first 2 enclosures logical ID is partially masked out where the 3rd one (which has a correct unique enclosure ID) is not. We pointed this out to Supermicro and were able to confirm that this address is supposed to be set during manufacturing and there was a problem with a certain batch of these enclosures where the logical ID was not set. We believe that the RAID controller is determining the ID based on the logical ID and since our first 2 enclosures have the same logical ID, they get the same enclosure ID. We also confirmed that 0000007F is the default which comes from LSI as an ID. The next pointer that helps confirm this could be a manufacturing problem with a run of JBODs is the fact that all 6 of the enclosures that have this problem begin with 00E. I believe that between 00E8 and 00EE Supermicro forgot to program the logical IDs correctly and neglected to recall or fix the problem post production. Fortunately for us, there is a tool to manage the WWN and logical ID of the devices from Supermicro: ftp://ftp.supermicro.com/utility/ExpanderXtools_Lite/. Our next step is to schedule a shutdown of these JBODs (after data migration) and reprogram the logical ID and see if it solves the problem. Update 06/28/12 #2: I just discovered this FAQ at Supermicro while Google searching for "lsi 0000007f": http://www.supermicro.com/support/faqs/faq.cfm?faq=11805. I still don't understand why, in the last several times we contacted Supermicro, they would have never directed us to this article :\

• C#/.NET Little Wonders: The ConcurrentDictionary

  - by James Michael Hare

  Once again we consider some of the lesser known classes and keywords of C#.  In this series of posts, we will discuss how the concurrent collections have been developed to help alleviate these multi-threading concerns.  Last week’s post began with a general introduction and discussed the ConcurrentStack<T> and ConcurrentQueue<T>.  Today's post discusses the ConcurrentDictionary<T> (originally I had intended to discuss ConcurrentBag this week as well, but ConcurrentDictionary had enough information to create a very full post on its own!).  Finally next week, we shall close with a discussion of the ConcurrentBag<T> and BlockingCollection<T>. For more of the "Little Wonders" posts, see the index here. Recap As you'll recall from the previous post, the original collections were object-based containers that accomplished synchronization through a Synchronized member.  While these were convenient because you didn't have to worry about writing your own synchronization logic, they were a bit too finely grained and if you needed to perform multiple operations under one lock, the automatic synchronization didn't buy much. With the advent of .NET 2.0, the original collections were succeeded by the generic collections which are fully type-safe, but eschew automatic synchronization.  This cuts both ways in that you have a lot more control as a developer over when and how fine-grained you want to synchronize, but on the other hand if you just want simple synchronization it creates more work. With .NET 4.0, we get the best of both worlds in generic collections.  A new breed of collections was born called the concurrent collections in the System.Collections.Concurrent namespace.  These amazing collections are fine-tuned to have best overall performance for situations requiring concurrent access.  They are not meant to replace the generic collections, but to simply be an alternative to creating your own locking mechanisms. Among those concurrent collections were the ConcurrentStack<T> and ConcurrentQueue<T> which provide classic LIFO and FIFO collections with a concurrent twist.  As we saw, some of the traditional methods that required calls to be made in a certain order (like checking for not IsEmpty before calling Pop()) were replaced in favor of an umbrella operation that combined both under one lock (like TryPop()). Now, let's take a look at the next in our series of concurrent collections!For some excellent information on the performance of the concurrent collections and how they perform compared to a traditional brute-force locking strategy, see this wonderful whitepaper by the Microsoft Parallel Computing Platform team here. ConcurrentDictionary – the fully thread-safe dictionary The ConcurrentDictionary<TKey,TValue> is the thread-safe counterpart to the generic Dictionary<TKey, TValue> collection.  Obviously, both are designed for quick – O(1) – lookups of data based on a key.  If you think of algorithms where you need lightning fast lookups of data and don’t care whether the data is maintained in any particular ordering or not, the unsorted dictionaries are generally the best way to go. Note: as a side note, there are sorted implementations of IDictionary, namely SortedDictionary and SortedList which are stored as an ordered tree and a ordered list respectively.  While these are not as fast as the non-sorted dictionaries – they are O(log2 n) – they are a great combination of both speed and ordering -- and still greatly outperform a linear search. Now, once again keep in mind that if all you need to do is load a collection once and then allow multi-threaded reading you do not need any locking.  Examples of this tend to be situations where you load a lookup or translation table once at program start, then keep it in memory for read-only reference.  In such cases locking is completely non-productive. However, most of the time when we need a concurrent dictionary we are interleaving both reads and updates.  This is where the ConcurrentDictionary really shines!  It achieves its thread-safety with no common lock to improve efficiency.  It actually uses a series of locks to provide concurrent updates, and has lockless reads!  This means that the ConcurrentDictionary gets even more efficient the higher the ratio of reads-to-writes you have. ConcurrentDictionary and Dictionary differences For the most part, the ConcurrentDictionary<TKey,TValue> behaves like it’s Dictionary<TKey,TValue> counterpart with a few differences.  Some notable examples of which are: Add() does not exist in the concurrent dictionary. This means you must use TryAdd(), AddOrUpdate(), or GetOrAdd().  It also means that you can’t use a collection initializer with the concurrent dictionary. TryAdd() replaced Add() to attempt atomic, safe adds. Because Add() only succeeds if the item doesn’t already exist, we need an atomic operation to check if the item exists, and if not add it while still under an atomic lock. TryUpdate() was added to attempt atomic, safe updates. If we want to update an item, we must make sure it exists first and that the original value is what we expected it to be.  If all these are true, we can update the item under one atomic step. TryRemove() was added to attempt atomic, safe removes. To safely attempt to remove a value we need to see if the key exists first, this checks for existence and removes under an atomic lock. AddOrUpdate() was added to attempt an thread-safe “upsert”. There are many times where you want to insert into a dictionary if the key doesn’t exist, or update the value if it does.  This allows you to make a thread-safe add-or-update. GetOrAdd() was added to attempt an thread-safe query/insert. Sometimes, you want to query for whether an item exists in the cache, and if it doesn’t insert a starting value for it.  This allows you to get the value if it exists and insert if not. Count, Keys, Values properties take a snapshot of the dictionary. Accessing these properties may interfere with add and update performance and should be used with caution. ToArray() returns a static snapshot of the dictionary. That is, the dictionary is locked, and then copied to an array as a O(n) operation.  GetEnumerator() is thread-safe and efficient, but allows dirty reads. Because reads require no locking, you can safely iterate over the contents of the dictionary.  The only downside is that, depending on timing, you may get dirty reads. Dirty reads during iteration The last point on GetEnumerator() bears some explanation.  Picture a scenario in which you call GetEnumerator() (or iterate using a foreach, etc.) and then, during that iteration the dictionary gets updated.  This may not sound like a big deal, but it can lead to inconsistent results if used incorrectly.  The problem is that items you already iterated over that are updated a split second after don’t show the update, but items that you iterate over that were updated a split second before do show the update.  Thus you may get a combination of items that are “stale” because you iterated before the update, and “fresh” because they were updated after GetEnumerator() but before the iteration reached them. Let’s illustrate with an example, let’s say you load up a concurrent dictionary like this: 1: // load up a dictionary. 2: var dictionary = new ConcurrentDictionary<string, int>(); 3:  4: dictionary["A"] = 1; 5: dictionary["B"] = 2; 6: dictionary["C"] = 3; 7: dictionary["D"] = 4; 8: dictionary["E"] = 5; 9: dictionary["F"] = 6; Then you have one task (using the wonderful TPL!) to iterate using dirty reads: 1: // attempt iteration in a separate thread 2: var iterationTask = new Task(() => 3: { 4: // iterates using a dirty read 5: foreach (var pair in dictionary) 6: { 7: Console.WriteLine(pair.Key + ":" + pair.Value); 8: } 9: }); And one task to attempt updates in a separate thread (probably): 1: // attempt updates in a separate thread 2: var updateTask = new Task(() => 3: { 4: // iterates, and updates the value by one 5: foreach (var pair in dictionary) 6: { 7: dictionary[pair.Key] = pair.Value + 1; 8: } 9: }); Now that we’ve done this, we can fire up both tasks and wait for them to complete: 1: // start both tasks 2: updateTask.Start(); 3: iterationTask.Start(); 4:  5: // wait for both to complete. 6: Task.WaitAll(updateTask, iterationTask); Now, if I you didn’t know about the dirty reads, you may have expected to see the iteration before the updates (such as A:1, B:2, C:3, D:4, E:5, F:6).  However, because the reads are dirty, we will quite possibly get a combination of some updated, some original.  My own run netted this result: 1: F:6 2: E:6 3: D:5 4: C:4 5: B:3 6: A:2 Note that, of course, iteration is not in order because ConcurrentDictionary, like Dictionary, is unordered.  Also note that both E and F show the value 6.  This is because the output task reached F before the update, but the updates for the rest of the items occurred before their output (probably because console output is very slow, comparatively). If we want to always guarantee that we will get a consistent snapshot to iterate over (that is, at the point we ask for it we see precisely what is in the dictionary and no subsequent updates during iteration), we should iterate over a call to ToArray() instead: 1: // attempt iteration in a separate thread 2: var iterationTask = new Task(() => 3: { 4: // iterates using a dirty read 5: foreach (var pair in dictionary.ToArray()) 6: { 7: Console.WriteLine(pair.Key + ":" + pair.Value); 8: } 9: }); The atomic Try…() methods As you can imagine TryAdd() and TryRemove() have few surprises.  Both first check the existence of the item to determine if it can be added or removed based on whether or not the key currently exists in the dictionary: 1: // try add attempts an add and returns false if it already exists 2: if (dictionary.TryAdd("G", 7)) 3: Console.WriteLine("G did not exist, now inserted with 7"); 4: else 5: Console.WriteLine("G already existed, insert failed."); TryRemove() also has the virtue of returning the value portion of the removed entry matching the given key: 1: // attempt to remove the value, if it exists it is removed and the original is returned 2: int removedValue; 3: if (dictionary.TryRemove("C", out removedValue)) 4: Console.WriteLine("Removed C and its value was " + removedValue); 5: else 6: Console.WriteLine("C did not exist, remove failed."); Now TryUpdate() is an interesting creature.  You might think from it’s name that TryUpdate() first checks for an item’s existence, and then updates if the item exists, otherwise it returns false.  Well, note quite... It turns out when you call TryUpdate() on a concurrent dictionary, you pass it not only the new value you want it to have, but also the value you expected it to have before the update.  If the item exists in the dictionary, and it has the value you expected, it will update it to the new value atomically and return true.  If the item is not in the dictionary or does not have the value you expected, it is not modified and false is returned. 1: // attempt to update the value, if it exists and if it has the expected original value 2: if (dictionary.TryUpdate("G", 42, 7)) 3: Console.WriteLine("G existed and was 7, now it's 42."); 4: else 5: Console.WriteLine("G either didn't exist, or wasn't 7."); The composite Add methods The ConcurrentDictionary also has composite add methods that can be used to perform updates and gets, with an add if the item is not existing at the time of the update or get. The first of these, AddOrUpdate(), allows you to add a new item to the dictionary if it doesn’t exist, or update the existing item if it does.  For example, let’s say you are creating a dictionary of counts of stock ticker symbols you’ve subscribed to from a market data feed: 1: public sealed class SubscriptionManager 2: { 3: private readonly ConcurrentDictionary<string, int> _subscriptions = new ConcurrentDictionary<string, int>(); 4:  5: // adds a new subscription, or increments the count of the existing one. 6: public void AddSubscription(string tickerKey) 7: { 8: // add a new subscription with count of 1, or update existing count by 1 if exists 9: var resultCount = _subscriptions.AddOrUpdate(tickerKey, 1, (symbol, count) => count + 1); 10:  11: // now check the result to see if we just incremented the count, or inserted first count 12: if (resultCount == 1) 13: { 14: // subscribe to symbol... 15: } 16: } 17: } Notice the update value factory Func delegate.  If the key does not exist in the dictionary, the add value is used (in this case 1 representing the first subscription for this symbol), but if the key already exists, it passes the key and current value to the update delegate which computes the new value to be stored in the dictionary.  The return result of this operation is the value used (in our case: 1 if added, existing value + 1 if updated). Likewise, the GetOrAdd() allows you to attempt to retrieve a value from the dictionary, and if the value does not currently exist in the dictionary it will insert a value.  This can be handy in cases where perhaps you wish to cache data, and thus you would query the cache to see if the item exists, and if it doesn’t you would put the item into the cache for the first time: 1: public sealed class PriceCache 2: { 3: private readonly ConcurrentDictionary<string, double> _cache = new ConcurrentDictionary<string, double>(); 4:  5: // adds a new subscription, or increments the count of the existing one. 6: public double QueryPrice(string tickerKey) 7: { 8: // check for the price in the cache, if it doesn't exist it will call the delegate to create value. 9: return _cache.GetOrAdd(tickerKey, symbol => GetCurrentPrice(symbol)); 10: } 11:  12: private double GetCurrentPrice(string tickerKey) 13: { 14: // do code to calculate actual true price. 15: } 16: } There are other variations of these two methods which vary whether a value is provided or a factory delegate, but otherwise they work much the same. Oddities with the composite Add methods The AddOrUpdate() and GetOrAdd() methods are totally thread-safe, on this you may rely, but they are not atomic.  It is important to note that the methods that use delegates execute those delegates outside of the lock.  This was done intentionally so that a user delegate (of which the ConcurrentDictionary has no control of course) does not take too long and lock out other threads. This is not necessarily an issue, per se, but it is something you must consider in your design.  The main thing to consider is that your delegate may get called to generate an item, but that item may not be the one returned!  Consider this scenario: A calls GetOrAdd and sees that the key does not currently exist, so it calls the delegate.  Now thread B also calls GetOrAdd and also sees that the key does not currently exist, and for whatever reason in this race condition it’s delegate completes first and it adds its new value to the dictionary.  Now A is done and goes to get the lock, and now sees that the item now exists.  In this case even though it called the delegate to create the item, it will pitch it because an item arrived between the time it attempted to create one and it attempted to add it. Let’s illustrate, assume this totally contrived example program which has a dictionary of char to int.  And in this dictionary we want to store a char and it’s ordinal (that is, A = 1, B = 2, etc).  So for our value generator, we will simply increment the previous value in a thread-safe way (perhaps using Interlocked): 1: public static class Program 2: { 3: private static int _nextNumber = 0; 4:  5: // the holder of the char to ordinal 6: private static ConcurrentDictionary<char, int> _dictionary 7: = new ConcurrentDictionary<char, int>(); 8:  9: // get the next id value 10: public static int NextId 11: { 12: get { return Interlocked.Increment(ref _nextNumber); } 13: } Then, we add a method that will perform our insert: 1: public static void Inserter() 2: { 3: for (int i = 0; i < 26; i++) 4: { 5: _dictionary.GetOrAdd((char)('A' + i), key => NextId); 6: } 7: } Finally, we run our test by starting two tasks to do this work and get the results… 1: public static void Main() 2: { 3: // 3 tasks attempting to get/insert 4: var tasks = new List<Task> 5: { 6: new Task(Inserter), 7: new Task(Inserter) 8: }; 9:  10: tasks.ForEach(t => t.Start()); 11: Task.WaitAll(tasks.ToArray()); 12:  13: foreach (var pair in _dictionary.OrderBy(p => p.Key)) 14: { 15: Console.WriteLine(pair.Key + ":" + pair.Value); 16: } 17: } If you run this with only one task, you get the expected A:1, B:2, ..., Z:26.  But running this in parallel you will get something a bit more complex.  My run netted these results: 1: A:1 2: B:3 3: C:4 4: D:5 5: E:6 6: F:7 7: G:8 8: H:9 9: I:10 10: J:11 11: K:12 12: L:13 13: M:14 14: N:15 15: O:16 16: P:17 17: Q:18 18: R:19 19: S:20 20: T:21 21: U:22 22: V:23 23: W:24 24: X:25 25: Y:26 26: Z:27 Notice that B is 3?  This is most likely because both threads attempted to call GetOrAdd() at roughly the same time and both saw that B did not exist, thus they both called the generator and one thread got back 2 and the other got back 3.  However, only one of those threads can get the lock at a time for the actual insert, and thus the one that generated the 3 won and the 3 was inserted and the 2 got discarded.  This is why on these methods your factory delegates should be careful not to have any logic that would be unsafe if the value they generate will be pitched in favor of another item generated at roughly the same time.  As such, it is probably a good idea to keep those generators as stateless as possible. Summary The ConcurrentDictionary is a very efficient and thread-safe version of the Dictionary generic collection.  It has all the benefits of type-safety that it’s generic collection counterpart does, and in addition is extremely efficient especially when there are more reads than writes concurrently.

• How to add an onclick event to a joint.js element?

  - by ahalbert

  I have a joint.js element in a DAG, and would like to be able to trigger an event by clicking on it. I could use $(selector).click(...) to do it, but I was wondering if there was a joint.js specific way of handling it, since that would probobly be better. One event I decided was a candidate for onclick was 'batch:stop' My code: var variable = new joint.shapes.basic.Rect({ name : label, id: label, onclick : function () {alert("hello");}, size: { width: width, height: height }, attrs: { text: { text: label, 'font-size': letterSize, 'font-family': 'monospace' }, rect: { fill : fillColor, width: width, height: height, rx: 5, ry: 5, stroke: '#555' } } }); variable.on('batch:stop', function (element) {alert(""); toggleEvidence(element.name);}); return variable; How should I add an onclick event?

• How do I use SharpSVN to programatically "add to ignore list" for a folder.

  - by Myster

  How do I use SharpSVN to programatically to add a folder to the ignore list? EDIT: Attempted: Here's what I've tried svnClient.GetProperty(new SvnUriTarget("svn://svn.foo.com/" + DatabaseName + "/"), SvnPropertyNames.SvnIgnore, out ignores); ignores += " Artifacts"; var args = new SvnSetPropertyArgs() { BaseRevision = ???, LogMessage = "update ignore list" }; svnClient.SetProperty(new Uri("svn://svn.foo.com/" + DatabaseName + "/"), SvnPropertyNames.SvnIgnore, ignores, args); But I don't know how to get the BaseRevision (I can get it manually, and that works, but all the combinations of GetProperty I tried don't seem to give it to me.) SOLUTION: Based on Bert's Answer SvnGetPropertyArgs getArgs = new SvnGetPropertyArgs(){}; string ignores = "Artifacts"; string result; if(svnClient.GetProperty(new SvnUriTarget("svn://svn.foo.com/" + ProjectName + "/trunk/"), SvnPropertyNames.SvnIgnore,out result)) { ignores = result + " Artifacts"; //TODO: check for existing & tidy formatting. } svnClient.SetProperty(UncPath.TrimEnd('\\'), SvnPropertyNames.SvnIgnore, ignores); SvnCommit(svnClient);
