• Can git switch branch without the modification

  - by hguser

  I have a project which have completed the basic models(at master), then I commit them. Then I create two branchs user and product using: git checkout -b user git checkout -b product git checkout user Then I add the codes in the user branch, but I found that I have to make some changes for the basic models. Then I switch to master: git checkout master But I found that the modification I made in the user branch is visible in the working directory now. How to avoid this? Since the change to master and modification will be frequency.

• What is __path__ useful for?

  - by Jason Baker

  I had never noticed the __path__ attribute that gets defined on some of my packages before today. According to the documentation: Packages support one more special attribute, __path__. This is initialized to be a list containing the name of the directory holding the package’s __init__.py before the code in that file is executed. This variable can be modified; doing so affects future searches for modules and subpackages contained in the package. While this feature is not often needed, it can be used to extend the set of modules found in a package. Could somebody explain to me what exactly this means and why I would ever want to use it?

• Apache and Rewrite Module

  - by Yvon Blais

  I created a file .htaccess in the /var/www directory., The rights are root root --wxrwxrwxr The content of the file is : Options +FollowSymlinks RewriteEngine on RewriteLogLevel 3 RewriteLog "/var/log/apache2/rewrite.log" RewriteRule ^(.*?)$ testphp.php When I call the page phpinfo.php, I've got: Loaded Modules ... mod_rewrite ... Therefore, the modules is loaded Afer each modification,I restared the server manually with sudo /etc/init.d/apache2 restart The error.log gives Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.2 with Suhosin-Patch configured -- resuming normal operations When I call a page anyone.htm or anyone.php, the rewrite.log does contain nothing and the real page is called. If I understand, the page anyone.php should be replaced by testphp.php Did I make siomething wrong ? Thanks

• Check if a symlink has changed

  - by BCS

  I have a daemon that, when it's started, loads its data from a directory that happens to be a symlink. Periodically, new data is generated and the symlink updated. I want a bash script that will check if the current symlink is the same as the old one (that the daemon started with) and if not, restart the daemon. My current thought is: if [[ ! -e $old_dir || $(readlink "$data_dir") == $(readlink "$old_dir") ]]; then echo restart ... ln "$(readlink "$data_dir")" "$old_dir" -sf else echo no restart fi The abstract requirement is: each time the script runs, it needs to check if a symlink on a given path now points to a something other than it did the last time and if so do something. (The alternative would be to check if the data at the path has changed but I don't see that being any cleaner.) My questions: Is this a good approach? Does anyone have a better idea? Where should I put $old_dir?

• Design guidelines for cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism (this is work assignment, not homework), This is my first time writing a design document, Our program display images for doctors, and we want to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas: Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• g++: Use ZIP files as input

  - by Notinlist

  We have the Boost library in our side. It consists of huge amount of files which are not changing ever and only a tiny portion of it is used. We swap the whole boost directory if we are changing versions. Currently we have the Boost sources in our SVN, file by file which makes the checkout operations very slow, especially on Windows. It would be nice if there were a notation / plugin to address C++ files inside ZIP files, something like: // @ZIPFS ASSIGN 'boost' 'boost.zip/boost' #include <boost/smart_ptr/shared_ptr.hpp> Are there any support for compiler hooks in g++? Are there any effort regarding ZIP support? Other ideas?

• Editing a 1MB file continuously, what's more efficient?

  - by kmels

  I've to be continuously editing a 1MB file, simulating a file system. I've to modify the directory of File Control Blocks, FAT, blocks, etc. Proffesor recommended overwriting the file every time an update is made. 1MB shouldn't take minutes to do that, but I don't like this way. Is it a FileChannel the way to go here? Also, I understand that if I edit a MappedByteBuffer, the content of the mapped file region is also edited immediately? i.e. is reflexive mapped? Thanks.

• C++ shared libraries

  - by saminny

  Hi, I am trying to get my head around the way shared libraries work in the c++ unix environment. I understand we only need header files and no shared libraries specification when compiling code. But if I want to create an executable or shared library from my compiled files, do I need to specify shared library dependencies (those are dynamic)? And do the paths of shared libraries need to match the path at runtime loading? I am using Linux 2.6.18-164.11.1.el5 #1 SMP x86_64 GNU/Linux I am having a problem where my code is not able to pick up a library at runtime. I have tried setting LD_LIBRARY_PATH and PATH. But at runtime when I run the executable, I get the following error: Error: librc.so: cannot open shared object file: No such file or directory Sam

• Live Mesh has screwed up my file permissions

  - by Jason

  I got the bright idea of using Live Mesh to sync up my development directories between my laptop and desktop machines. It appears that the permission on any new files that are added through Live Mesh do not inherit permissions from the parent directory. Now I cannot overwrite the permissions on those files. I keep getting an "Access is Denied" error when attempting to do so, even if I am running Windows Explorer as administrator. I have two questions: How can I modify the file permissions to allow them to inherit again? Has anyone used Live Mesh to do this sort of thing? Or should I be using FolderShare instead?

• AppEngine and Django: including a template file

  - by PythonPower

  As the title suggests, I'm using Google App Engine and Django. I have quite a bit of identical code across my templates and would like to reduce this by including template files. So, in my main application directory I have the python handler file, the main template, and the template I want to include in my main template. I would have thought that including {% include "fileToInclude.html" %} would work on its own but that simply doesn't include anything. I assume I have to set something up, maybe using TEMPLATE_DIRS, but can't figure it out on my own. EDIT: I've tried: TEMPLATE_DIRS = (os.path.join(os.path.dirname(__file__), 'templates'), ) But to no avail. I'll try some other possibilities too.

• How to get Path Separator in Perl?

  - by ram

  In case of Java, we can get the path separator using System.getProperty("path.separator"); Is there a similar way in Perl? All I want to do is to find a dir, immediate sub directory. Say I am being given two argumens $a and $b; I am splitting the first one based on the path separator and joining it again except the last fragment and comparing with the second argument. The problem is my code has to be generic and for that I need to know whats the system dependent path separator is? Could you help if there is any way to get it? TIA

• How do you set a cookie to be accessible across the entire domain in Javascript

  - by Tzarkov

  I suppose there should be a way to set a cookie to be accessible from the entire domain nevermind from which directory you are setting the cookie. Say in mypage.com/blue/index.php y set the cookie "colour=blue;" this way: document.cookie = "colour" + "=" + "blue" + "; expires=" + expireDate.toGMTString() + "; path=/"; Using this code, the cookie retrieval function in mypage.com/home.php can't access the content of the cookie. If it was just from first level directories that the cookie needs to be set, we would be ok by doing path=../ instead of path=/ But how do you go about writing generic code that sets a cookie that is accessible from any page in that domain not minding how deep in the file structure is the page the cookie is being set from?

• How to write multiple files from one NSData object?

  - by Kevin Cupp

  Hi there! I'm writing an iPhone app that includes in-app purchasing. It downloads a zip file, then I unzip the file using the popular NSData category (zlibDeflate) which outputs the uncompressed file into an NSData object. The zip file contains multiple files in it which I need to write to the Documents directory. How can I write each file separately from this one NSData object? writeToFile just writes the whole thing to one file. Thank you and let me know if you need any more information.

• Recursively disabling CONFIG dependencies on linux kernel builds

  - by Corey Henderson

  When configuring a Linux kernel, I normally start with my distribution's kernel config file. I often want to turn off some entries, but they are sometimes unchangeable because other CONFIG options that depend on it are enabled. I can look up the dependencies manually, which often have dependencies of their own. It can be pretty time consuming to did through them all, especially if you're trying to turn off something like CONFIG_KALLSYMS. Is there a way to specify a CONFIG option you want gone, and have all dependencies automatically selected/disselected as nessisary for you? I looked through all the make options and in the scripts directory, and didn't see anything available for this.

• c# EnumerateFiles wildcard returning non matches?

  - by Sam Underhill

  As a simplified example I am executing the following IEnumerable<string> files = Directory.EnumerateFiles(path, @"2010*.xml", SearchOption.TopDirectoryOnly).ToList(); In my results set I am getting a few files which do no match the file pattern. According to msdn searchPattern wildcard is "Zero or more characters" and not a reg ex. An example is that I am getting a file name back as "2004_someothername.xml". For information there are in excess of 25,000 files in the folder. Does anyone have any idea what is going on?

• VBScript Writing to Server Text File

  - by Keyfer Mathewson

  I have created a VBScript which pulls the service tag, username, and computer name from a computer. What I need to do now is compile this information in a text document. How it's set up is as follows: We have an Active Directory Server, with a folder for login scripts. I have created a batch file to run this .vbs script, and the script works well so far. What I now need is for a file on the AD server, called "logging.txt", to be populated with the information that is created with the .vbs script. This is the script I have so far: 'Get Dell Service Tag Info set ProSet = GetObject("winmgmts:").InstancesOf("Win32_BIOS") Set ProSet1 = GetObject("winmgmts:").InstancesOf("Win32_SystemEnclosure") For each Pro in ProSet For each Pro1 in ProSet1 ServiceTag=Pro.SerialNumber wscript.echo ServiceTag exit for Next exit for Next 'get username and computername, could also be asked in a batch Set oShell = WScript.CreateObject("WScript.Shell") Set oShellEnv = oShell.Environment("Process") sComputerName = oShellEnv("ComputerName") sUsername = oShellEnv("username") wscript.echo sComputerName & " " & sUsername Thank you very much in advance!

• Runtime Error in asp.net site?

  - by Surya sasidhar

  hi, I developed a website in asp.net and i place the site in online. I upload my site in online by using CuteFTP. After uploading when i type my url it is giving error like this... Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

• Windows Service Printing Behaviour

  - by Andre

  Alright, I was tasked to develop a Windows Service that listens to a directory for files that are dropped in it, read them, delete them and print out a report. I installed the service on my work laptop (Win 7 x86) and a test machine (XP x86) under a User account at first. It would do everything as it should except the print the report. No errors, nothing. Then I made it run under Local System and it produced a "No printers found" exception. Converting the app to a Console Application and running on these machines gave the desired result. OK, so now I was assuming that there are security "stuff" involved. Then I installed the service on a Server 2008 x64 machine (under Local System) and it just worked. Can anybody explain to me why this is happening? Why does the service allow printing from Server OS but not from a Desktop OS or am I missing something very obvious?

• compiling QGIS Plugin using make

  On a fresh mac os x 10.8 install, i've Quantum GIS Installed from Kingchaos binaries and running fine. I'm trying to develop a plugin for QGIS, and using Plugin Builder. The skel that Plugin Builder, produces, should work off-the-shelf, but it does not compile using the makefile. Somewhere python can't find (pyuic.py), and it searches for (/Users/kyngchaos/...), path.

• How to ignore an exception and continue processing a foreach loop?

  - by Barry Dysert

  I have a test program that is supposed to loop over all the files under C:. It dies when it hits the "Documents and Settings" folder. I'd like to ignore the error and keep looping over the remaining files. The problem is that the exception is thrown in the foreach, so putting a try/catch around the foreach will cause the loop to exit. And putting a try/catch after the foreach never fires (because the exception is thrown in the foreach). Is there any way to ignore the exception and continue processing the loop? Here's the code: static void Main(string[] args) { IEnumerable<string> files = Directory.EnumerateFiles(@"C:\", "*.*", SearchOption.AllDirectories); foreach (string file in files) // Exception occurs when evaluating "file" Console.WriteLine(file); }
