permissions

问题 I am writing a program to mimic the cp utility. However, I cannot get the file permissions to work correctly. I know that they are stored in the structure stat and stored in the st_mode field with stat . My issue is that I do not get the write permission for the group or other categories, i.e. I get -rwxr-xr-x as the permissions for the file even though the source file is -rwxrwxrwx . The statement where I set the permissions is below. if ( (dest_fd = open(dest_file, O_WRONLY|O_CREAT, (stats

问题 I am writing a single page application in React and Redux (with a Node.js backend). I want to implement role-based access control and want to control the display of certain parts (or sub parts) of the app. I'm going to get permissions list from Node.js, which is just an object with such structure: { users: 'read', models: 'write', ... dictionaries: 'none', } key is protected resource, value is user permission for this resource (one of: none , read , write ). I'm storing it into redux state.

问题 If an android application wants to use the Alarm Manager Service, then which permissions the application needs to have? I have tested that it seems that application does not need to have any permission to use the Alarm Manager Service. Is that true? 回答1: Yes, it is true. You do not have to add any special service. Keep in mind that when the handset is restarted the alarms you have set will be lost, so you may want to re-schedule them at boot time, which requires the android.permission.RECEIVE

问题 I am using a linux system and need to experiment with some permissions on a set of nested files and directories. I wonder if there is not some way to save the permissions for the files and directories, without saving the files themselves. In other words, I'd like to save the perms, edit some files, tweak some permissions, and then restore the permissions back onto the directory structure, keeping the changed files in place. Does that make sense? 回答1: hm. so you need to 1) read file
