  • Instance caching in Objective C

    - by zoul
    Hello! I want to cache the instances of a certain class. The class keeps a dictionary of all its instances and when somebody requests a new instance, the class tries to satisfy the request from the cache first. There is a small problem with memory management though: The dictionary cache retains the inserted objects, so that they never get deallocated. I do want them to get deallocated, so that I had to overload the release method and when the retain count drops to one, I can remove the instance from cache and let it get deallocated. This works, but I am not comfortable mucking around the release method and find the solution overly complicated. I thought I could use some hashing class that does not retain the objects it stores. Is there such? The idea is that when the last user of a certain instance releases it, the instance would automatically disappear from the cache. NSHashTable seems to be what I am looking for, but the documentation talks about “supporting weak relationships in a garbage-collected environment.” Does it also work without garbage collection? Clarification: I cannot afford to keep the instances in memory unless somebody really needs them, that is why I want to purge the instance from the cache when the last “real” user releases it. Better solution: This was on the iPhone, I wanted to cache some textures and on the other hand I wanted to free them from memory as soon as the last real holder released them. The easier way to code this is through another class (let’s call it TextureManager). This class manages the texture instances and caches them, so that subsequent calls for texture with the same name are served from the cache. There is no need to purge the cache immediately as the last user releases the texture. We can simply keep the texture cached in memory and when the device gets short on memory, we receive the low memory warning and can purge the cache. This is a better solution, because the caching stuff does not pollute the Texture class, we do not have to mess with release and there is even a higher chance for cache hits. The TextureManager can be abstracted into a ResourceManager, so that it can cache other data, not only textures.

  • Is arithmetic overflow/underflow generally checked in .Net framework methods?

    - by YWE
    For example, let's use the Add method of the ArrayList class. If I am using the default compiler settings in Visual Studio C# project in which arithmetic overflow is not checked, would ArrayList.Add() throw an OverflowException if I added too many items? Would surrounding the method call with checked or unchecked make any difference? BTW, I would write a test program to determine the answer to this question if I had Visual Studio available to me right now.

  • HTML Encoding with ASP.NET

    - by Corin
    I am currently html encoding all user entered text before inserting/updating a db table record. The problem is that on any subsequent updates, the previously encoded string is reencoded. This endless loop is starting to eat up alot of column space in my tables. I am using parameterized queries for all sql statements but am wondering would it be safe to just let the .NET Framework handle this part without the HTML Encoding?

  • Change library load order at run time (like LD_PRELOAD but during execution)

    - by tylerl
    How do I change the library a function loads from during run time? For example, say I want to replace the standard printf function with something new, I can write my own version and compile it into a shared library, then put "LD_PRELOAD=/my/library.so" in the environment before running my executable. But let's say that instead, I want to change that linkage from within the program itself. Surely that must be possible... right?

  • Using cp command in linux shell, how do I copy a whole directory into another directory?

    - by Dmitry Supranovich
    I have a directory, let's say, "work": ~/work/ This directory has some sub-folders (d1, d2...) in it and files in these sub-folders. I want to make a backup copy in the same folder, so it would be like: ~/backup/work/ However, when I use cp -r ./work ./backup the folder "work" is not copied, only its subfoders (so now it's ~/backup/d1 ~/backup/d2...) Any idea how to make it work? I'm quite new to shell, so I'm missing something :)

  • Django - urls.py - Filenames with a hash/pound (#) sign?

    - by miya
    I'm using django and realized that when the filename that the user wants to access (let's say a photo) has the pound sign, the entry in the url.py does not match. Any ideas? url(r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root': MEDIA_ROOT}, it just says: "/home/user/project/static/upload/images/hello" does not exist when actually the name of the file is: hello#world.jpg Thanks, Nico

  • iPhone dev - showing two locations on the map

    - by Brian
    Now I have the coordinate of two locations, let say locationA with latitude 40 and longitude -80, locationB with latitude 30 and longitude -70, I want to create a mapView that I can see both locations with appropriate viewing distance. I got the new coordinate by finding the midpoint (in this example, {35, -75}), but the question is, How can I get an appropriate viewing distance? In particular, how can I calculate CLLocationDistance (if I'm using MKCoordinateRegionMakeWithDistance) or MKCoordinateSpan (if I'm using MKCoordinateSpanMake). Thanks in advance.

  • Saving an XML that has invalid characters

    - by BDotA
    there are code snippets that strip the invalid characters inside a string before we save it as an XML ... but I have one more problem: Let's say my user wants to have a column name like "[MyColumnOne] ...so now I do not want to strip these "[","] well because these are the ones that user has defined and wants to see them so if I use some codes that are stripping the invalid characters they are also removing "[" and "[" but in this case I still need them to be saved... what can I do?
