permissions

问题 To my knowledge, Java's File class does not support to change the file's permission and last modified date. Is there any proper way to do this in a cross-platform style? 回答1: I'm looking at the Java 6 documentation, and there is a setLastModified() method, as well as setReadable(...) and setWritable(...) and setExecutable(...) methods (all in the java.io.File class). So yes, there is a way... 来源： https://stackoverflow.com/questions/459622/how-to-change-the-files-permission-and-last-modified

问题 I am looking at ways to implement an authorization (not authentication) scheme in my app. There are currently two roles in the system: A and B, but there may be more. User's only have one role. Basically, the I have it set up now is with two database tables. One is for role-based permissions on a model, and the other is for specific user-based permissions. I am thinking that this way, users can have a set of default permissions based on their role-based permissions, but then they can also

问题 I currently have a tree structure containing data elements; on each of these, it is possible to perform basic CRUD operations. From here, I need to implement per-user permissions for each of these four actions. So a given user could be given Create and Read, but no Update or Delete permission. These permissions would then cascade down the tree to any children of the permitted object; therefore, that given user would have Create and Read for any child objects of the root object. What's the

问题 I am using logstash to push all the text logs from storage to elastic search. My storage size is about 1 TB. To Start with I have started to push 368 GB data (may be few hundred thousand files) to elastic search but logstash is failing with following error. {:timestamp=>"2014-05-15T00:41:12.436000-0700", :message=>"/root/share/archive_data/sessionLogs/965c6f46-1a5e-4820-a68d-7c32886972fc/Log.txt: file grew, old size 0, new size 1557420", :level=>:debug, :file=>"filewatch/watch.rb", :line=>"81

问题 I am using Visual Studio 2013(C#) and SSAS 2014 (through AMO). I need to prepare a list of permissions of a given user in the SSAS database. For example, domainName\userName has permissions on the 2 dimensions out of 5 available in the database. I like to prepare a list like this. Dimension Name | Attributes | Dimension used in Cube | VisualTotal | Mdx Set (if any) | Role Name I can loop through Roles and members and get some information. But it seems that it is a long shot and will not be

问题 I know there is getPermissions() method but I don't know how to use it. How can I check using JSch, if user can read files? 回答1: First, you should generally ask a functional question (what do you want to achive), to get an useful answer. You ask for an implementation/technical detail, hence my possibly useless technical answer: SftpATTRS.getPermissions() returns numerical representation of *nix permissions: https://en.wikipedia.org/wiki/File_system_permissions#Numeric_notation It's on its own

问题 Following my previous question I'm now trying to execute a batch file trough NSIS code in order to successfully setup the postgres installation after it is being unzipped. The batch file contains command for initializing the database but it fails because of permission restrictions. I am on a Win7 x64 PC. My user account is the administrator and I start the Setup.exe with Run as adminitrator option. This is the error I get: C:\Program Files (x86)\Poker Assistant>cd "pgsql\bin" C:\Program Files

问题 How does Android perform security checks on native code? Suppose we declare permission X in AndroidManifest.xml, does it mean we inherit that same permission X in our native code? 回答1: How does Android perform security checks? There are basically two ways the permissions are enforced. First of all on kernel level: each installed app is assigned a unique (linux) user id and each time your app is started Android will spawn a process and sets the user id of that process to whatever your app
