Difference between load-time dynamic linking and run-time dynamic linking

折月煮酒 提交于 2019-11-28 16:34:19
When loading programs into memory, what is the difference between load-time dynamic linking and run-time dynamic linking? load-time linking is when symbols in the library, referenced by the executable (or another library) are handled when the executable/library is loaded into memory, by the operating system. Run-time linking is when you use an API provided by the OS or through a library to load a DLL or DSO when you need it, and perform the symbol resolution then. I know more about Linux DSOs than Windows DLL's but the principle should be the same. .NET libraries may differ. In linux, plugin

loading ELF file in C in user space

无人久伴 提交于 2019-11-28 16:26:08
I am trying to load an ELF file compiled with "gcc -m32 test.c -o test.exe" on Linux in a 64 bit x86 environment. I am trying to load that 32bit file (test.exe) inside a user space ELF loader which has the following core logic (32bit ELF). The problem is that calling into the returned start address results in a segmentation fault core dump. Here is the code: void *image_load (char *elf_start, unsigned int size) { Elf32_Ehdr *hdr = NULL; Elf32_Phdr *phdr = NULL; unsigned char *start = NULL; Elf32_Addr taddr = 0; Elf32_Addr offset = 0; int i = 0; unsigned char *exec = NULL; Elf32_Addr estart = 0

Setting Loader.active to false doesn't release item immediately

安稳与你 提交于 2019-11-28 12:14:49
问题 I have a use case where depending on the presence or absence of a property value an object referencing it is either created or removed. I am using a Loader for the purpose, where the active property is bound to the property, that is when the property has a non-null value the loader is activated, when it is set to null it is deactivated. However the problem is that the loader doesn't release its item immediately, so for a moment the item references a null property, thus is unable to access

how does php autoloader works

Does php class Autoloader opens a file and checks for the class name? I have been looking on how is it actually implemented. One thing I know that its recursive? If I'm wrong please let me know As mentioned overhere : autoloader brief over view How PHP Autoloader works The PHP Autoloader searches recursively in defined directories for class, trait and interface definitions. Without any further configuration the directory in which the requiring file resides will be used as default class path. File names don't need to obey any convention. All files are searched for class definitions. Files which

How to load a local video in React using webpack?

筅森魡賤 提交于 2019-11-27 23:48:05
问题 I can't seem to figure out how to get an html5 video to render in a react app from local files. Literally the only way I've been able to get this to work is like this: <video src="http://www.w3schools.com/html/movie.mp4" controls /> Here's what I've tried 1. Including the path directly <video src={require('path/to/file.mp4')} controls /> which returns an error Module parse failed: /path/to/file.mp4 Line 1: Unexpected token ILLEGAL You may need an appropriate loader to handle this file type. 2

Android: LoaderCallbacks.OnLoadFinished called twice

早过忘川 提交于 2019-11-27 17:26:31
I noticed strange situation using Android Loaders and Fragments. When I invoke LoaderManager.initLoader() after orientation change onLoadFinished is not called (although documentation suggests I should be prepared for this) but it is called twice after this. Here is link to post in google groups which describe the same situation https://groups.google.com/forum/?fromgroups#!topic/android-developers/aA2vHYxSskU . I wrote sample application in which I only init simple Loader in Fragment.onActivityCreated() to check if this happens and it does. Anyone noticed this? You can put the initLoader()

How to use images in css with Webpack

问题 I am making a React w/ Webpack setup and am struggling to do what seems like should be a simple task.

Webpack outputs to a dist folder, but I can't figure out how to get images there. Here is my webpack
