shared

问题 I have seen a few answers to this on SOF but most of these are concerned with the use of subdomains, of which none have worked for me. The common one being that the use of session.cookie_domain , which from my understanding will only work with subdomains. I am interested in a solution that deals with deals with entirely different domains (and includes the possibility of subdomains). Unfortunately project deadlines being what they are, time is not on my side, so I turn to SOF's expertise and

问题 How do I determine what process is attached to a shared memory segment? awagner@tree:/home/awagner$ ipcs -m ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x00000000 0 root 777 102400 1 0x00000000 32769 root 774 96 1 dest 0x00000000 98306 awagner 600 393216 2 dest 0x00000000 131075 awagner 600 393216 2 dest i.e. how do I figure out which two processes are attached to shmid 98306? 回答1: I don't think you can do this with the standard tools. You can use ipcs -mp

问题 What is the delay load equivalent in unix based system. I have a code foo.cpp , While compiling with gcc I link it to shared objects(totally three .so files are there.). Each of the .so file for different option. ./foo -v needs libversion.so ./foo -update needs libupdate.so I need the symbol for those libraries should be resolved only at the run time. ./foo -v should not break even if libupdate.so library is not there. It is working in windows using the delay load option(in properties of dll)

问题 I have a shared library loaded using dlopen (with the flags RTLD_NOW | RTLD_GLOBAL ). If this library is using functions from the main program, then it does not unload. So I end up with the same code for this shared lib, even if I unloaded (using dlclose ), changed, compiled, (re)load it. My goal is actually to reload the same library after making changes to it, so that I do not have to relaunch the whole program to test out my code. I am using g++ 4.2.3, on Linux Ubuntu 10.04. (edit) solved:

问题 I am migrating a client's SourceSafe repository (3 projects) to SVN and two of the projects share source files. (These projects are separate products - with different names and release versions, etc) Has SVN resolved this shortcoming? How do people generally handle this scenario? Of the options I know about/can think of Use the external or extern or whatever for SVN. I hear this is not a good option for various reasons Create a new project (maybe called shared) that contains the source. The

问题 I am describing a problem for which it took me quite some time to learn the answer. The "GenericKeychain" example is a good start at providing a wrapper for sharing keychain data between applications when using the accessGroup in the init. However, implementing this in my app yielded an obscure error code (which took forever to locate) -25243, which means: No access control. I ran Apple's example app (GenericKeychain) on my iPad only to get the same error. Huh? Does Apple's documentation fail

问题 I expected that: linking with .o file, and linking with .a file archived from the .o file, should have no difference. But the fact is not. I have got 2 source files, each declaring 1class+1 static object+1 function, and a main.cpp that called one of the functions $cat First.cpp #include<stdio.h> struct First{ First(){printf("First\n");} }; void f1(){printf("f1\n");}//Not called in main static First f_obj; $cat Second.cpp #include<stdio.h> struct Second{ Second(){printf("Second\n");} }; void

问题 We have 2 applications: web-based (PHP) and Desktop (VB) sharing the same database (Hostgator). Our web app has a fast access to the database (it's localhost). Our desktop application suffers with slow access and frequent timeouts. What's the best approach to this kind of issue? Should we share a database? Are there any other solution. Thanks 回答1: Some possible solutions: Get a faster DB server Move your database to a server that is closer to the desktop(s) Host your webserver/DB at the
