  • Eclipse Plugin that Opens a Command Line in Eclipse

    - by Jonas Laufu
    I'm looking for an Eclipse plug-in that shows a system (independent) command line in a view that is ideally synchronized with the current project's local path. So basically a shell within Eclipse. The reason for this is to be able to execute custom build commands and script faster than specifying them as launch configurations or having to open a command prompt every time I start eclipse.

  • NSXMLParser Memory Allocation Efficiency for the iPhone

    - by Staros
    Hello, I've recently been playing with code for an iPhone app to parse XML. Sticking to Cocoa, I decided to go with the NSXMLParser class. The app will be responsible for parsing 10,000+ "computers", all which contain 6 other strings of information. For my test, I've verified that the XML is around 900k-1MB in size. My data model is to keep each computer in an NSDictionary hashed by a unique identifier. Each computer is also represented by a NSDictionary with the information. So at the end of the day, I end up with a NSDictionary containing 10k other NSDictionaries. The problem I'm running into isn't about leaking memory or efficient data structure storage. When my parser is done, the total amount of allocated objects only does go up by about 1MB. The problem is that while the NSXMLParser is running, my object allocation is jumping up as much as 13MB. I could understand 2 (one for the object I'm creating and one for the raw NSData) plus a little room to work, but 13 seems a bit high. I can't imaging that NSXMLParser is that inefficient. Thoughts? Code... The code to start parsing... NSXMLParser *parser = [[NSXMLParser alloc] initWithData: data]; [parser setDelegate:dictParser]; [parser parse]; output = [[dictParser returnDictionary] retain]; [parser release]; [dictParser release]; And the parser's delegate code... -(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { if(mutableString) { [mutableString release]; mutableString = nil; } mutableString = [[NSMutableString alloc] init]; } -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(self.mutableString) { [self.mutableString appendString:string]; } } -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if([elementName isEqualToString:@"size"]){ //The initial key, tells me how many computers returnDictionary = [[NSMutableDictionary alloc] initWithCapacity:[mutableString intValue]]; } if([elementName isEqualToString:hashBy]){ //The unique identifier if(mutableDictionary){ [mutableDictionary release]; mutableDictionary = nil; } mutableDictionary = [[NSMutableDictionary alloc] initWithCapacity:6]; [returnDictionary setObject:[NSDictionary dictionaryWithDictionary:mutableDictionary] forKey:[NSMutableString stringWithString:mutableString]]; } if([fields containsObject:elementName]){ //Any of the elements from a single computer that I am looking for [mutableDictionary setObject:mutableString forKey:elementName]; } } Everything initialized and released correctly. Again, I'm not getting errors or leaking. Just inefficient. Thanks for any thoughts!

    Ok, I have a hardcoded string I declare like this name = u"Par Catégorie" I have a # -- coding: utf-8 -- magic header, so I am guessing it's converted to utf-8 Down the road it's outputted to xml through xml_output.toprettyxml(indent='....', encoding='utf-8') And I get a UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 3: ordinal not in range(128) Most of my data is in French and is ouputted correctly in CDATA nodes, but that one harcoded string keep ... I don't see why an ascii codec is called. what's wrong ?

  • Dataset and SQLCe in .net 4

    - by Tyler Edwards
    I'm trying to build a SQLCe table structure dynamically using a dataset as the temporary table structure... Is there a SqlConnection string that will work with SqlCe? There used to be a SqlCeConnection...but I don't find that in the 4.0 framework? Has something replaced this? If the answer is L2S or Entity Framework...can I add columns to SqlCe tables at runtime? If so...how?

    I have a couple of concerns, I'm busy building a normal .mobi site for a client, so basically how I understand this is keep it simply since most phones do not support JavaScript and have a small screen etc. So I build a mobi site using only content and basic links. Now my question is how do mobi widgets work on a mobile site? I've googled and could not find a answer? Is this possible at all?

  • Windows forms application blocks after station lock

    - by Silviu
    We're having a serious issue at work. We've discovered that after the station where the client was running is locked/unlocked the client is blocked. No repaint. So the UI thread is blocked with something. Looking at the callstack of the UI thread (thread 0) using windbg we see that a UserPreferenceChanged event gets raised. It is marshalled through a WindowsFormsSynchronizationContext using it's controlToSend field to the UI. It gets blocked by a call to the marshalling control. The method called is MarshaledInvoke it builds a ThreadMethodEntry entry = new ThreadMethodEntry(caller, method, args, synchronous, executionContext); This entry is supposed to do the magic. The call is a synchronous call and because of that (still in the MarshaledInvoke of the Control class) the wait call is reached: if (!entry.IsCompleted) { this.WaitForWaitHandle(entry.AsyncWaitHandle); } The last thing that i can see on the stack is the WaitOne called on the previously mentioned AsyncWaitHandle. This is very annoying because having just the callstack of the runtime and not one of our methods being invoked we cannot really point to a bug in our code. I might be wrong, but I'm guessing that the marshaling control is not "marshaling" to the ui thread. But another one...i don't really know which one because the other threads are being used by us and are blocked...maybe this is the issue. But none of the other threads are running a message loop. This is very annoying. We had some issues in the past with marshaling controls to the right ui thread. That is because the first form that is constructed is a splash form. Which is not the main form. We used to use the main form to marshal call to the ui thread. But from time to time some calls would go to a non ui thread and some grids would broke with a big red X on them. I fixed this by creating a specific class: public class WindowsFormsSynchronizer { private static readonly WindowsFormsSynchronizationContext = new WindowsFormsSynchronizationContext(); //Methods are following that would build the same interface of the synchronization context. } This class gets build as one of the first objects in the first form being constructed. We've noticed some other strange thing. Looking at the heap there are 7 WindowsFormsSynchronizationContext objects. 6 of these have the same instance of controlToSend, and the other one has some different instance of controlToSend. This last one is the one that should marshal the calls to the UI. I don't have any other idea...maybe some of you guys had this same issue?

  • idlj Ignoring "#pragma prefix"

    - by Benny
    I have an IDL file that has a "#pragma prefix" directive, but whenever I use idlj to build the Java code, it ignores this and generates an _id without the prefix specified. This is a big problem because when _is_a is used, it always returns false, since my generated code does not contain the expected prefix. Please help! Thanks in advance!

  • How to deploy a rar file to jboss

    - by Joshua
    Refer original post here for a reference to the original issue. What plugin should I use to deploy the jackrabbit rar as a separate entity to the jboss installation. I tried the rar module within the maven-ear-plugin which was actually packaging this within the ear file and the rar plugin which seems to be used for packaging a rar. Currently I am using the antrun plugin to deploy the rar file and it's associated ds.xml, is there a different plugin to automate direct deployment.

  • Opt-out of copy constructor

    - by sheepsimulator
    This might be a silly question, but... I've been writing a number of classes that utilize non-copyable members. These classes are never initialized via the copy constructor in my source. When I try to compile without supplying my own copy-constructor, g++ throws out many errors about how it can't build a default copy constructor, due to the non-copyable member objects. Is there a way to tell the compiler to just not give me a copy constructor?
