  • magento _redirect with parameters that have + or /

    - by epeleg
    seems like a call to $this->_redirect('*/*/myaction',$myargs); does not properly escape the arguments so if $myargs=array(p1=>'string that has + or / within it') the created URL will be something like: ..../myaction/?p1/string%20that%20has%20+%20or%20/%20within%20it causing the getParams collection on the action to have p1 with value 'string that has or ' <- plus sign missing and value broken and ' within it' with no value or something similar. is there any standard way I should handle the arguments before passing them to _redirect ?

  • Autowire not working in junit test

    - by Dave Paroulek
    I'm sure I'm missing something simple. bar gets autowired in the junit test, but why doesn't bar inside foo get autowired? @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration({"beans.xml"}) public class BarTest { @Autowired Object bar; @Test public void testBar() throws Exception { //this works assertEquals("expected", bar.someMethod()); //this doesn't work, because the bar object inside foo isn't autowired? Foo foo = new Foo(); assertEquals("expected", foo.someMethodThatUsesBar()); } }

  • UITextView disabling text selection

    - by dizy
    I'm having a hard time getting the UITextView to disable the selecting of the text. I've tried: canCancelContentTouches = YES; I've tried subclassing and overwriting: - (BOOL)canPerformAction:(SEL)action withSender:(id)sender (But that gets called only After the selection) - (BOOL)touchesShouldCancelInContentView:(UIView *)view; (I don't see that getting fired at all) - (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view; (I don't see that getting fired either) What am I missing ?

    - by NawaMan
    Hi all. How can I get the size of a versioned file/files? This seems to be a very common operation but I can't find how (Am I missing something?). Well, I can get it indirectly by catting it and count the bytes but this is very slow. Any help would be appropriated.

  • Given this demo, How do I make HTML content area fit to viewport height?

    - by viatropos
    I just made this demo extracting out what I'm trying to accomplish: Autosize Main Content Area I want the pink/yellow area to act according to these rules: Minimum height is the size of its content (which is variable) IF content size is smaller than viewport size Otherwise minimum height is such that it adjusts to fill the window. Checking out the source to that demo, what am I missing? I feel like this is a pretty easy case that shouldn't require javascript. Any ideas?

  • Ubuntu in failed state after upgrade from 10.04 to 10.10 - How to recover?

    - by Harvey
    I was running Ubuntu 10.04 and attempted to upgrade to 10.10. I have a really slow connection (DSL 128kbits/sec) and copying the upgrade files took about 26 hours. I of course let it run unattended. When I came back, I notice the following 3 dlgs: 1. Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg -- configure -a). 2. gpk-update-icon Distribution upgrades available maverick 10.10 (stable) [more information] [Do no show this again] [Cancel] [Ok] 3. gpk-update-icon Security updates available The following important updates are available for your computer: libwebkit-1.0-2-dbg - Web content engine library for Gtk+ - Debugging symbols libcupsimage2 - Common UNIX Printing System(tm) - Raster image library ... What is the best response to all of this? I went through something similar in an attempted network upgrade from 8.04 to 10.04 and had to reload the unbootable machine fresh from distribution media (all data was lost). I'd like to avoid that here. I have not yet responded to the dialogs, and want to make sure the system is still bootable and not lose my data this time.

  • SSL Authentication with Certificates: Should the Certificates have a hostname?

    - by sixtyfootersdude
    Summary JBoss allows clients and servers to authenticate using certificates and ssl. One thing that seems strange is that you are not required to give your hostname on the certificate. I think that this means if Server B is in your truststore, Sever B can pretend to be any server that they want. (And likewise: if Client B is in your truststore...) Am I missing something here? Authentication Steps (Summary of Wikipeida Page) Client Server ================================================================================================= 1) Client sends Client Hello ENCRIPTION: None - highest TLS protocol supported - random number - list of cipher suites - compression methods 2) Sever Hello ENCRIPTION: None - highest TLS protocol supported - random number - choosen cipher suite - choosen compression method 3) Certificate Message ENCRIPTION: None - 4) ServerHelloDone ENCRIPTION: None 5) Certificate Message ENCRIPTION: None 6) ClientKeyExchange Message ENCRIPTION: server's public key => only server can read => if sever can read this he must own the certificate - may contain a PreMasterSecerate, public key or nothing (depends on cipher) 7) CertificateVerify Message ENCRIPTION: clients private key - purpose is to prove to the server that client owns the cert 8) BOTH CLIENT AND SERVER: - use random numbers and PreMasterSecret to compute a common secerate 9) Finished message - contains a has and MAC over previous handshakes (to ensure that those unincripted messages did not get broken) 10) Finished message - samething Sever Knows The client has the public key for the sent certificate (step 7) The client's certificate is valid because either: it has been signed by a CA (verisign) it has been self-signed BUT it is in the server's truststore It is not a replay attack because presumably the random number (step 1 or 2) is sent with each message Client Knows The server has the public key for the sent certificate (step 6 with step 8) The server's certificate is valid because either: it has been signed by a CA (verisign) it has been self-signed BUT it is in the client's truststore It is not a replay attack because presumably the random number (step 1 or 2) is sent with each message Potential Problem Suppose the client's truststore has certs in it: Server A Server B (malicous) Server A has hostname www.A.com Server B has hostname www.B.com Suppose: The client tries to connect to Server A but Server B launches a man in the middle attack. Since server B: has a public key for the certificate that will be sent to the client has a "valid certificate" (a cert in the truststore) And since: certificates do not have a hostname feild in them It seems like Server B can pretend to be Server A easily. Is there something that I am missing?

  • Creating a "permanent" Cocoa object

    - by quixoto
    I have an object factory that hands out instances of certain "constant" objects. I'd like these objects to be protected against bad memory management by clients. This is how I've overridden the class's key methods. Am I missing anything (code or other considerations)? - (id)retain { return self; } - (NSUInteger)retainCount { return UINT_MAX; } - (void)release { // nothing. }
