permissions

问题 I am trying to programmatically read/write a file in /data directory on a rooted phone. I first shell execute su to make sure my program gets super user access, which works fine. I am able to read/write files in /data thru shell execs commands inside my program, but I am getting " Permission denied " java.io.IOException when using Android File or other APIs. How to use the APIs to read/write to /data on a rooted phone ? this is obviously possible as programs such as Root Explorer does it.

问题 I was debugging a seg fault in a Linux app that was caused by a program trying to change a static constant array structure (so the data was in the read-only section of the ELF and subsequently loaded in a page that was then given read-only permission).

GDB did this without any complaints, and reading the value back proved it had

I've been searching for this issue for a while, but never found the code, which would work. Some of them tried to make it work with Form Requests, but I'm interested in using Middleware. 回答1: Create middleware: php artisan make

问题 OK, I have done some creative searches and am kind of hitting a road block. I am trying to use the linux program "sox." I am trying to call it from my PHP script. The script DOES work if I use the command line. However, when I use PHP exec, it does not work. Example: sox file1.mp3 file2.mp3 tempfile.mp3 -V3 ("V3" specifies a verbose output) When executing in the command line as "User X" or as root, I am able to create the new file. However, when I execute the command as: <?php exec('sox file1

问题 After pushing files to our server, the following post-receive hook is executed: #!/bin/sh export GIT_WORK_TREE=/home/user/www/ git checkout -f However, files get a very odd 600 permission, and folders 700 upon checkout. This is not what I expect (on our other servers we get 644 and 755 ). From this thread I understand that git does not set permissions, so git is not to blame. My question is: what is? How can I figure out what the cause is of this issue? I have already temporarily solved it by

问题 I'm using SQL Server 2008 R2 and I've created a TVP that I want to use as a parameter to a stored proc but I get a message saying that it can't be found or I don't have permission. I can use the TVP in a script or in the body of the stored proc, but when I try to use it as a parameter I get the error. Any thoughts?
