• System.Web.Caching vs. Enterprise Library Caching Block

  - by ESV

  For a .NET component that will be used in both web applications and rich client applications, there seem to be two obvious options for caching: System.Web.Caching or the Ent. Lib. Caching Block. What do you use? Why? System.Web.Caching Is this safe to use outside of web apps? I've seen mixed information, but I think the answer is maybe-kind-of-not-really. a KB article warning against 1.0 and 1.1 non web app use The 2.0 page has a comment that indicates it's OK: http://msdn.microsoft.com/en-us/library/system.web.caching.cache(VS.80).aspx Scott Hanselman is creeped out by the notion The 3.5 page includes a warning against such use Rob Howard encouraged use outside of web apps I don't expect to use one of its highlights, SqlCacheDependency, but the addition of CacheItemUpdateCallback in .NET 3.5 seems like a Really Good Thing. Enterprise Library Caching Application Block other blocks are already in use so the dependency already exists cache persistence isn't necessary; regenerating the cache on restart is OK Some cache items should always be available, but be refreshed periodically. For these items, getting a callback after an item has been removed is not very convenient. It looks like a client will have to just sleep and poll until the cache item is repopulated. Memcached for Win32 + .NET client What are the pros and cons when you don't need a distributed cache?

• NSURLErrorBadURL error

  - by Victor jiang

  My iphone app called Google Local Search(non javascript version) to behave some search business. Below is my code to form a url: NSString *url = [NSString stringWithFormat:@"http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=%@", keyword]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:url]]; [request setHTTPMethod:@"GET"]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[[NSError alloc] init] autorelease]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; When the keyword refers to english characters, it works fine, but when refers to chinese characters(encoded in UTF8, such as '???' whose UTF8 code is 'e5a4a9 e5ae89 e997a8'), it will report NSURLErrorBadURL error(-1000, Returned when a URL is sufficiently malformed that a URL request cannot be initiated). Why? Then I carry out further investigation, I use Safari and type in the url below: http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=??? It also works, and the output I got from Macsniffer is: /ajax/services/search/local?v=1.0&q=%E5%A4%A9%E5%AE%89%E9%97%A8 So I write a testing url directly in my app NSString *url = [NSString stringWithFormat:@"http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=%E5%A4%A9%E5%AE%89%E9%97%A8"]; And what I got from the Macsniffer is some other thing: /ajax/services/search/local?v=1.0&q=1.687891E-28750X1.417C0001416CP-102640X1.4CC2D04648FBP-9999-1.989891E+0050X1.20DC00184CC67P-953E8E99A8 It seems my keyword "%E5%A4%A9%E5%AE%89%E9%97%A8" was translated into something else. So how can I form a valid url? I do need help!

• aapt not found when building new Android app in NetBeans

• Paperclip and Amazon S3 Issue

  - by Jimmy

  Hey everyone, I have a rails app running on Heroku. I am using paperclip for some simple image uploads for user avatars and some other things, I have S3 set as my backend and everything seems to be working fine except when trying to push to S3 I get the following error: The AWS Access Key Id you provided does not exist in our records. Thinking I mis-pasted my access key and secret key, I tried again, still no luck. Thinking maybe it was just a buggy key I deactivated it and generated a new one. Still no luck. Now for both keys I have used the S3 browser app on OS X and have been able to connect to each and view my current buckets and add/delete buckets. Is there something I should be looking out for? I have my application's S3 and paperclip setup like so development: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] test: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] production: bucket: (unique_name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] has_attached_file :cover, :styles => { :thumb => "50x50" }, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => ":class/:id/:style/:filename" Note: I just added the (unique name) bits, those aren't actually there--I have also verified bucket names, but I don't even think this is getting that far. I also have my heroku environment vars setup correctly and have them setup on dev

• part of contact are repeated after each writing the same contact (Android 2.0+)

  - by Bogus

  Hello, I met this problem at writing contacts by API for Android 2.0 or greater. Each time I write the same contact which already exist in my account (Google account) I got some part of contact aggregated ok but other did not. For example fields like FN, N, ORG, TITLE always are in one copy but TEL, EMAIL, ADR are added extra so after 2nd writing the same contact I have 2 copy the same TEL or EMAIL. How to force API engine to not repeate existed data ? Code: ArrayList ops = new ArrayList(); ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI) .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, accountType) .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, accountName) .build()); ... // adding phone number ContentProviderOperation.Builder builder = ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI); builder.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0); builder.withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE); builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, phoneValue); builder.withValue(ContactsContract.CommonDataKinds.Phone.TYPE, phoneType); // work/home builder.withValue(ContactsContract.CommonDataKinds.Phone.LABEL, phoneLabel); ops.add(builder.build()); ... try { contentResolver.applyBatch(ContactsContract.AUTHORITY, ops); } catch (Exception e) { // } I tried add: AGGREGATION_MODE on AGGREGATION_MODE_DISABLED. but it changed nothing. I will glad for any hint in this case. BR, Bogus

• Try/Catch with jquery ajax request

  - by Anthony

  I am trying to build a Google Chrome extension that makes an ajax request. Something similar to the GMail Checker extension. The problem is that when I do the request using jquery, and I put in the wrong username/password, it fails silently, with the error callback function ignored. If I move the ajax call out of the background.html script (where I can't see the requests in the developer window), to the options.html script, I get a dialog box to re-authenticate. If I hit cancel, THEN the jquery error callback fires. But in the original model extension (again, the Gmail checker), they use plain (non-jquery) ajax calls with a try/catch, and if I put in the wrong credentials, I get an alert saying as much. I tried wrapping the entire jquery call in a try/catch, like so: try { $.ajax({ type: "POST", url: someurl, contentType : "text/xml", data: somedata, username: user, password: pass, success: function(data,status,xhr){ alert("Hurrah!"); }, error: function(xhr, status, error){ alert("Error!" + xhr.status); }, dataType: "xml" }); } catch(e) { alert("You messed something up!"); } But still nothing. Is the error due to it being asynchronous, or is Chrome not returning the request as an error since it wants to re-prompt for credentials? Or do I just not know how to use try/catch? Update Here is a very slimmed down version of how the model code does the request: var req = new XMLHttpRequest(); req.onreadystatechange = function() { try { if ( req.readyState == 4 ) { //Do some stuff with results } } catch (ex) { alert('Error parsing response.'); } } try { req.send (data); } catch (ex) { alert ('Something went wrong with the request.'); }

• Building a Drupal Newsletter Module for handling Newsletter Articles

  - by Michael T. Smith

  We're building a module for generating HTML for email newsletters. We've looked into using a few other modules (SimpleNews, MailChimp, among others), but due to various requirements, it'll be easier and better for us to build a custom solution. Being a new Drupal developer, I'm a bit worried about handling this in a "non-Drupal" way. That being said, my plan is to setup a vocabulary with Newsletters as a term and the actual Newsletters as sub-terms, like so: Newsletters (term) - Newsletter A (sub-term) - Newsletter B (sub-term) This has the added benefit of being able to organize where articles were published (besides just on the site.) The question, though, is how to handle the different Newsletter issues. I could go another level deeper in the vocabulary, like so: Newsletters (term) - Newsletter A (sub-term) - Issue - 2010-03-01 - Issue - 2010-03-02 - Newsletter B (sub-term) - Issue - 2010-03-01 - Issue - 2010-03-08 But I'm wondering if this is adding a bit too much complexity. Once I have this taxonomy setup, when the user went to add new newsletters it would also create a node (content type: newsletter), and when he/she went to add new issues, it would also create a node (content type: issue.) Those would then be the landing pages for that content. So, the question is is there a better way for handling this structure? Is this a Drupal-like solution?

• Encoding a email address that can be used as part of a URL in codeigniter

  - by freedayum

  Is there a way to encode a email address that can be used as a part of a url in codeigniter?. I need to decode back the email address from the url. What I am trying to do is just a -forgotten password recovery- thing. I send a confirmation link to the user's email address, the link needs to be like ../encodedEmail/forgottenPasswordCode (with the forgottenPasswordCode updated in the db for the user with the submitted email). When the user visits that link, I decode the email(if the email - forgottenPasswordCode pair is in the table), i allow them to reset their password (and i reset forgottenPasswordCode back to null). I could just do a loop -checking the table with a select query- (or) -set that forgottenPasswordCode column unique, so i keep generating on a insert failure(would that be a lot faster ?)- until I generate a forgottenPasswordCode that doesn't already exist in the table. But the guy I do this for would not accept it this way:). He wants the checking be done with the user's email, he thinks its much faster. I am working with codeigniter, I used its encode() function, it seems to produce characters like '-slashes-' at times that breaks the encoded-email-string. Any other ideas?

• Linq, Left Join and Dates...

  - by BitFiddler

  So my situation is that I have a linq-to-sql model that does not allow dates to be null in one of my tables. This is intended, because the database does not allow nulls in that field. My problem, is that when I try to write a Linq query with this model, I cannot do a left join with that table anymore because the date is not a 'nullable' field and so I can't compare it to "Nothing". Example: There is a Movie table, {ID,MovieTitle}, and a Showings table, {ID,MovieID,ShowingTime,Location} Now I am trying to write a statement that will return all those movies that have no showings. In T.SQL this would look like: Select m.* From Movies m Left Join Showings s On m.ID = s.MovieID Where s.ShowingTime is Null Now in this situation I could test for Null on the 'Location' field but this is not what I have in reality (just a simplified example). All I have are non-null dates. I am trying to write in Linq: From m In dbContext.Movies _ Group Join s In Showings on m.ID Equals s.MovieID into MovieShowings = Group _ From ms In MovieShowings.DefaultIfEmpty _ Where ms.ShowingTime is Nothing _ Select ms However I am getting an error saying 'Is' operator does not accept operands of type 'Date'. Operands must be reference or nullable types. Is there any way around this? The model is correct, there should never be a null in the Showings:ShowTime table. But if you do a left join, and there are no show times for a particular movie, then ShowTime SHOULD be Nothing for that movie... Thanks everyone for your help.

• C# unaccurate timer?

  - by Ivan

  Hi there, I'm developing an application and I need to get the current date from a server (it differs from the machine's date). I receive the date from the server and with a simple Split I create a new DateTime: globalVars.fec = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, int.Parse(infoHour[0]), int.Parse(infoHour[1]), int.Parse(infoHour[2])); globalVars is a class and fec is a public static variable so that I can access it anywhere in the application (bad coding I know...). Now I need to have a timer checking if that date is equal to some dates I have stored in a List and if it is equal I just call a function. List<DateTime> fechas = new List<DateTime>(); Before having to obtain the date from a server I was using computer's date, so to check if the dates matched I was using this: private void timerDatesMatch_Tick(object sender, EventArgs e) { DateTime tick = DateTime.Now; foreach (DateTime dt in fechas) { if (dt == tick) { //blahblah } } } Now I have the date from the server so DateTime.Now can't be used here. Instead I have created a new timer with Interval=1000 and on tick I'm adding 1 second to globalVars.fec using: globalVars.fec = globalVars.fec.AddSeconds(1); But the clock isn't accurate and every 30 mins the clock loses about 30 seconds. Is there another way of doing what I'm trying to do? I've thought about using threading.timer instead but I need to have access to other threads and non-static functions. Thanks in advance, Ivan

• Character set issues with Oracle Gateways, SQL Server, and Application Express

  - by Brian Deterling

  I am migrating data from a Oracle on VMS that accesses data on SQL Server using heterogeneous services (over ODBC) to Oracle on AIX accessing the SQL Server via Oracle Gateways (dg4msql). The Oracle VMS database used the WE8ISO8859P1 character set. The AIX database uses WE8MSWIN1252. The SQL Server database uses "Latin1-General, case-insensitive, accent-sensitive, kanatype-insensitive, width-insensitive for Unicode Data, SQL Server Sort Order 52 on Code Page 1252 for non-Unicode Data" according to sp_helpsort. The SQL Server databases uses nchar/nvarchar or all string columns. In Application Express, extra characters are appearing in some cases, for example 123 shows up as %001%002%003. In sqlplus, things look ok but if I use Oracle functions like initcap, I see what appear as spaces between each letter of a string when I query the sql server database (using a database link). This did not occur under the old configuration. I'm assuming the issue is that an nchar has extra bytes in it and the character set in Oracle can't convert it. It appears that the ODBC solution didn't support nchars so must have just cast them back to char and they showed up ok. I only need to view the sql server data so I'm open to any solution such as casting, but I haven't found anything that works. Any ideas on how to deal with this? Should I be using a different character set in Oracle and if so, does that apply to all schemas since I only care about one of them.

• How to get around batch file processing limit

  - by Patrick Cuff

  I have a Windows batch file that processes all the files in a given directory. I have 206,783 files I need to process: for %%f in (*.xml) do call :PROCESS %%f goto :STOP :PROCESS :: do something with the file program.exe %1 > %1.new set /a COUNTER=%COUNTER%+1 goto :EOF :STOP @echo %COUNTER% files processed When I run the batch file, the following output is written: 65535 files processed As part of the processing, an output file is created for each file procesed, with a .new extension. When I do a dir *.new it reports 65,535 files exist. So, it appears my command environment has a hard limit on the number of files it can recognize, and that limit is 64K - 1. Is there a way to extend the command environment to manage more than 64K - 1 files? If not, would a VBScript or JavaScript be able to process all 206,783 files? I'm running on Windows 2003 server, Enterprise Edition, 32-bit. UPDATE It looks like the root cause of my issue was with the built-in Windows "extract" command for ZIP files. The files I have to process were copied from another system via a ZIP file. My server doesn't have a ZIP utility installed, just the native Windows commands. I right-clicked on the ZIP file, and did an "Extract all...", which apparently just extracted the first 65,535 files. I downloaded and installed 7-zip onto my server, unzipped all the files, and my batch script worked as intended.

• Presenting UINavigationController modally -- problem setting up tool and nav bar items in root view controller viewDidLoad

  - by Bogatyr

  In my iOS app I'm creating and presenting a UINavigationController modally like so: MyViewController *myvc = [[[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil] autorelease]; UINavigationController *navVC = [[[UINavigationController alloc] initWithRootViewController:myvc] autorelease]; [self presentModalViewController:navVC animated:YES]; In the MyViewController viewDidLoad I'm creating and setting toolbar items for the navigation controller's toolbar, like so: self.navigationController.toolbar.items = [NSArray arrayWithObjects:(items...), nil]; the problem I'm having is that the items don't show up. If instead I call a method from MyViewController's viewDidLoad method that adds the toolbar items via performSelector:withObject:afterDelay:0, then it works perfectly. So there's obviously some race condition going on here with the initial presentation of the UINavigationController, initialization of its toolbar/navbar, and the initialization of the nav bar's specified initial root view controller. I verified in the debugger that the root view controller's viewDidLoad is called after the UINavigationController's viewDidLoad method. In fact, the root view controller's viewDidLoad method is not called until presentModalViewController: is called, and the UINavigationController's viewDidLoad is called within initWithRootViewController, so doesn't that imply that the UINavigationController object should be "all ready to go", including its nav bar and toolbars? I thought at first that the navigation controller's toolbar object may not exist yet at MyViewController's viewDidLoad time, but it clearly does. At least, NSLog shows that it is not nil during MyViewController's viewDidLoad method. In fact, the UINavigationController's toolbar object is identical at both times: in the root view controller's viewDidLoad, and in the "setupToolbar" method that I called with performSelector:withObject:afterDelay, so it's not getting "re-initialized" somehow. So, what's going on here? Why aren't my toolbar modifications "sticking" in MyViewController's viewDidLoad, and why does performing them in the next iteration of the runloop (performSelector:withObject:afterDelay:0) make it work? What is the "right" way of setting up initial navbar / toolbar items in code from the rootViewController of the UINavigationController?

• Fully-loaded UIViewController losing all it's data after adding to scroll view

  - by clozach

  Summary I'm repurposing Apple's Page Control project. In loadScrollViewWithPage:, the view controllers that I'm adding to the scroll view appear on screen without their initialized values, as if displayed directly from the nib. Specifics Here's the code that appears to be working when I step through it: CBFullScreenViewController *controller = [viewControllers objectAtIndex:page]; if ((NSNull *)controller == [NSNull null]) { controller = [[CBFullScreenViewController alloc] init]; // Populate the view from the corresponding CBImage object CBImage *imageObject = [imageArray objectAtIndex:page]; BOOL bookmarked = [imageObject.bookmarked boolValue]; controller.bookmarkButton.highlighted = bookmarked; NSString *subtitle = imageObject.subtitle; controller.closedSubtitleLabel.text = subtitle; // <-- snip...more initialization --> // controller.delegate = self; [viewControllers replaceObjectAtIndex:page withObject:controller]; [controller release]; } // add the controller's view to the scroll view if (nil == controller.view.superview) { CGRect frame = scrollView.frame; frame.origin.x = frame.size.width * page; frame.origin.y = 0; controller.view.frame = frame; [scrollView addSubview:controller.view];//<< controller and subviews } // all have non-null, seemingly // valid values at this point Here's the init method in CBFullScreenViewController: - (id)init { if ((self = [super initWithNibName:@"CBFullScreenViewController" bundle:nil])) { self.cover = [[UIImageView alloc] init]; self.homeButton = [[UIButton alloc] init]; self.tabView = [[UIButton alloc] init]; self.closedSubtitleLabel = [[UILabel alloc] init]; self.openSubtitleLabel = [[UILabel alloc] init]; // <-- snip...more initialization --> // } return self; } While troubleshooting this for the last 2 hours has helped me track down some unrelated memory leaks, I can't for the life of me figure out what's happening to the values I'm putting into my view! Oh, it's probably worth mentioning that I've got @synthesize for each of my outlets, and they're all hooked up in IB. Screenshot here.

• Asterisk Manager API SIPPeers - Permission Denied

  - by Matt H

  I'm wanting to use the asterisk manager api to show the status of all my SIP lines in a PHP web interface. I thought I'd start simple and use telnet to see it working. So I created a user in /etc/asterisk/manager.conf [portal] secret = password read = all,system,call,log,verbose,command,agent,user Then telnet to localhost on port 5038 This is what I get. asterisk ~ # telnet localhost 5038 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Asterisk Call Manager/1.0 Action: login Username: portal Secret: 8u9sdgk Events: off Response: Success Message: Authentication accepted Action: SIPPeers Response: Error Message: Permission denied Why am I getting permission denied? I thought the user has basically full access? Do I need to restart asterisk to make this work? I didn't restart it. On the other hand, I was able to log in which makes me think that the manager.conf has been reloaded as the portal user didn't exist before. Any ideas?

• SMO restore of SQL database doesn't overwrite

  - by Tom H.

  I'm trying to restore a database from a backup file using SMO. If the database does not already exist then it works fine. However, if the database already exists then I get no errors, but the database is not overwritten. The "restore" process still takes just as long, so it looks like it's working and doing a restore, but in the end the database has not changed. I'm doing this in Powershell using SMO. The code is a bit long, but I've included it below. You'll notice that I do set $restore.ReplaceDatabase = $true. Also, I use a try-catch block and report on any errors (I hope), but none are returned. Any obvious mistakes? Is it possible that I'm not reporting some error and it's being hidden from me? Thanks for any help or advice that you can give! function Invoke-SqlRestore { param( [string]$backup_file_name, [string]$server_name, [string]$database_name, [switch]$norecovery=$false ) # Get a new connection to the server [Microsoft.SqlServer.Management.Smo.Server]$server = New-SMOconnection -server_name $server_name Write-Host "Starting restore to $database_name on $server_name."

• Outlook Interop Send Message from Account

  - by Reiste

  Okay, the specs have changed on this one somewhat. Maybe someone can help me with this new problem. Manually, what the user is doing is opening an new message in Outlook (2007 now) which has the "From..." field exposed. They open this up, select a certain account from the Global Address List, and send the message on behalf of that account. Is this possible to do? I can get the AddressEntry from the Global address list like so: AddressList list = null; foreach (AddressList addressList in _outlookApp.Session.AddressLists) { if (addressList.Name.ToLower().Equals("global address list")) { list = addressList; break; } } if (list != null) { AddressEntry entry = null; foreach (AddressEntry addressEntry in list.AddressEntries) { if (addressEntry.Name.ToLower().Equals("outgoing mail account")) { entry = addressEntry; break; } } } But I'm not sure I can make an Account type from the Address Entry. It seems to happen manually, when they select the address to send from. How do I mirror this in the Interop? Thanks! (My Original Question): I developed a small C# program to send email using the Outlook 2007 interop. The client required that the mail not be send using the default account - they had a secondary account they needed used. No problem - I used the Microsoft.Office.Interop.Outlook.Account class to access the availabled accounts, and choose the correct one. Now, it turns out they need this to work in Outlook 2003. Of course, the Account class doesn't exist in the Outlook interop 11.0. How can I achieve the same thing with Outlook 2003? Thanks in advance.

• CData section not finished problem

• Java+DOM: How do I convert a DOM tree without namespaces to a namespace-aware DOM tree?

  - by java.is.for.desktop

  Hello, everyone! I receive a Document (DOM tree) from a certain API (not in JDK). Sadly, this Document is not namespace-aware. As far as I know DOM, once generated, namespace-awareness can't be "added" afterwards. When converting this Document using a Transformer to a string, the XML is correct. Elements have xmlns:... attributes and name prefixes. But from the DOM point of view, there are no namespaces and no prefixes. I need to be able to convert this Document into a new Document which is namespace-aware. Yes, I could do this by just converting it to a string and back to DOM with namespaces enabled. But: nodes of the original tree have user-objects set. Converting to string and back would make a mapping of these user-objects to the new Document very complicated, if not impossible. So I really need a way to convert non-namespace DOM to namespace DOM. Are there any more-or-less straightforward solutions for this? Worst case (what I'm hoping to avoid) would be to manually iterate through old Document tree and create new namespace-aware Node for each old Node. Doing so, one had to manually "parse" namespace prefixes, watch out for xmlns-attributes, and maintain a mapping between prefixes and namespace-URIs. Lots of things to go wrong.

• How can I use Convert.ChangeType to convert string into numerics with group separator?

  - by Loic

  Hello, I want to make a generic string to numeric converter, and provide it as a string extension, so I wrote the following code: public static bool TryParse<T>( this string text, out T result, IFormatProvider formatProvider ) where T : struct try { result = (T)Convert.ChangeType( text, typeof( T ), formatProvider ); return true; } catch(... I call it like this: int value; var ok = "123".TryParse(out value, NumberFormatInfo.CurrentInfo) It works fine until I want to use a group separator: As I live in France, where the thousand separator is a space and the decimal separator is a comma, the string "1 234 567,89" should be equals to 1234567.89 (in Invariant culture). But, the function crashes! When a try to perform a non generic conversion, like double.Parse(...), I can use an overload which accepts a NumberStyles parameter. I specify NumberStyles.Number and this time it works! So, the questions are : Why the parsing does not respect my NumberFormatInfo (where the NumberGroupSeparator is well specified to a space, as I specified in my OS) How could I make work the generic version with Convert.ChangeTime, as it has no overload wich accepts a NumberStyles parameter ?

• Cannot turn off autocommit in a script using the Django ORM

  - by Wes

  I have a command line script that uses the Django ORM and MySQL backend. I want to turn off autocommit and commit manually. For the life of me, I cannot get this to work. Here is a pared down version of the script. A row is inserted into testtable every time I run this and I get this warning from MySQL: "Some non-transactional changed tables couldn't be rolled back". #!/usr/bin/python import os import sys django_dir = os.path.abspath(os.path.normpath(os.path.join(os.path.dirname(__file__), '..'))) sys.path.append(django_dir) os.environ['DJANGO_DIR'] = django_dir os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings' from django.core.management import setup_environ from myproject import settings setup_environ(settings) from django.db import transaction, connection cursor = connection.cursor() cursor.execute('SET autocommit = 0') cursor.execute('insert into testtable values (\'X\')') cursor.execute('rollback') I also tried placing the insert in a function and adding Django's commit_manually wrapper, like so: @transaction.commit_manually def myfunction(): cursor = connection.cursor() cursor.execute('SET autocommit = 0') cursor.execute('insert into westest values (\'X\')') cursor.execute('rollback') myfunction() I also tried setting DISABLE_TRANSACTION_MANAGEMENT = True in settings.py, with no further luck. I feel like I am missing something obvious. Any help you can give me is greatly appreciated. Thanks!

• Generating %pc relative address of constant data

  - by Hudson

  Is there a way to have gcc generate %pc relative addresses of constants? Even when the string appears in the text segment, arm-elf-gcc will generate a constant pointer to the data, load the address of the pointer via a %pc relative address and then dereference it. For a variety of reasons, I need to skip the middle step. As an example, this simple function: const char * filename(void) { static const char _filename[] __attribute__((section(".text"))) = "logfile"; return _filename; } generates (when compiled with arm-elf-gcc-4.3.2 -nostdlib -c -O3 -W -Wall logfile.c): 00000000 <filename>: 0: e59f0000 ldr r0, [pc, #0] ; 8 <filename+0x8> 4: e12fff1e bx lr 8: 0000000c .word 0x0000000c 0000000c <_filename.1175>: c: 66676f6c .word 0x66676f6c 10: 00656c69 .word 0x00656c69 I would have expected it to generate something more like: filename: add r0, pc, #0 bx lr _filename.1175: .ascii "logfile\000" The code in question needs to be partially position independent since it will be relocated in memory at load time, but also integrate with code that was not compiled -fPIC, so there is no global offset table. My current work around is to call a non-inline function (which will be done via a %pc relative address) to find the offset from the compiled location in a technique similar to how -fPIC code works: static intptr_t __attribute__((noinline)) find_offset( void ) { uintptr_t pc; asm __volatile__ ( "mov %0, %%pc" : "=&r"(pc) ); return pc - 8 - (uintptr_t) find_offset; } But this technique requires that all data references be fixed up manually, so the filename() function in the above example would become: const char * filename(void) { static const char _filename[] __attribute__((section(".text"))) = "logfile"; return _filename + find_offset(); }

• Redirect on Ajax Jquery Call

  - by Mark Estrada

  Hi, I am newbie to ajax here and I know somebody would have encountered this problem already. I have a legacy app built on Spring MVC, it has a interceptor(filter) that redirects the user to the login page whenever there is no session. public class SessionCheckerInterceptor extends HandlerInterceptorAdapter { public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { HttpSession session = request.getSession(); // check if userInfo exist in session User user = (User) session.getAttribute("user"); if (user == null) { response.sendRedirect("login.htm"); return false; } return true; } } For non-xmlhttp request, this works fine.. but when I try to use ajax in my application, everything gets weird, it is not able to redirect to the login page correctly. As check the value of the xhr.status = 200 textStatus = parseError errorThrown = "Invalid JSON -Markup of my HTML Login Page- $(document).ready(function(){ jQuery.ajax({ type: "GET", url: "populateData.htm", dataType:"json", data:"userId=SampleUser", success:function(response){ //code here }, error: function(xhr, textStatus, errorThrown) { alert('Error! Status = ' + xhr.status); } }); }); I checked on my firebug that there is a 302 HTTP response but I am not sure how to catch the response and redirect the user to the login page. Any idea here? Thanks.

• Do the ‘up to date’ guarantees for values of Java's final fields extend to indirect references?

  - by mattbh

  The Java language spec defines semantics of final fields in section 17.5: The usage model for final fields is a simple one. Set the final fields for an object in that object's constructor. Do not write a reference to the object being constructed in a place where another thread can see it before the object's constructor is finished. If this is followed, then when the object is seen by another thread, that thread will always see the correctly constructed version of that object's final fields. It will also see versions of any object or array referenced by those final fields that are at least as up-to-date as the final fields are. My question is - does the 'up-to-date' guarantee extend to the contents of nested arrays, and nested objects? An example scenario: Thread A constructs a HashMap of ArrayLists, then assigns the HashMap to final field 'myFinal' in an instance of class 'MyClass' Thread B sees a (non-synchronized) reference to the MyClass instance and reads 'myFinal', and accesses and reads the contents of one of the ArrayLists In this scenario, are the members of the ArrayList as seen by Thread B guaranteed to be at least as up to date as they were when MyClass's constructor completed? I'm looking for clarification of the semantics of the Java Memory Model and language spec, rather than alternative solutions like synchronization. My dream answer would be a yes or no, with a reference to the relevant text.
