• Unittest test case only touches the file name

  - by Chen OT

  I was told that unittest is fast and the tests which touches DB, across network, and touches FileSystem are not unittest. In one of my testcases, its input are the file names (amount about 300~400) under a specific folder. Although these input are part of file system, the execution time of this test is very fast. Should I moved this test, which is fast but touches file system, to higher level test?

• Open file with java application [migrated]

  - by Giaphage47

  I am using Ubuntu. I would like to have a user be able to double-click (or whatever they have set to open a file) on the save file for a java game i'm making, and have the game start and automatically load the save. How could I make the game launch instead of opening the file, and then pass the save's file name or location as an argument? Would i have to have the game create a new mime type the first time it ran, or something similar, so that Ubuntu knows what to do with the save when the user tries to open it?

• A proper file monitoring tool for Windows with notifications

  - by nevvermind

  Developing in PHP, I'm usually confronted with various log files: apache, web apps, error logs etc. I'm currently using Notepad++ with the option to notify me when a file has changed. But when I need to monitor many files, I end up with too many tabs opened. I've used some of these, but they were lacking some basic stuff (like double clicking on the file to open it; oh, c'mon). What do you guys use for monitoring file changes? I needn't be "modern" or fancy. Just a simple "Hey, this file was changed. Here, click on it to open". (Maybe I'll end up making one myself, but I need to learn some more Java).

• How do I see all of the directories shared using Nautilus Sharing Options?

  - by skyblue

  When you share a directory using samba, you can do this system-wide by editing the /etc/samba/smb.conf file (the advanced way) or by right-clicking a directory using Nautilus and selecting 'Sharing Options' (the easy way). However, while I can see what directories are shared system-wide by looking at /etc/samba/smb.conf, if I share directories using Nautilus, I do not know what directories that I (or other users) have shared. So how do I list all the directories that have been shared by samba using Nautilus Sharing Options for all the users on a system?

• Download a file over an active SSH session

  - by Oli

  So I'm SSHed into my Ubuntu server from my Ubuntu desktop. I'm at a certain path and I want to download a file to my local filesystem (preferably the path I was at before I entered the SSH session). I could mount SSH and pull the file across by mouse but what if I was trying to get a root file and logging in by root directly is disallowed? Even if that wasn't the case (it isn't now), surely there must be a simple way of pulling back a file over an active SSH connection. Surely!

• Structuring an input file

  - by Ricardo

  I am in the process of structuring a small program to perform some hydraulic analysis of pipe flow. As I am envisioning this, the program will read an input file, store the input parameters in a suitable way, operate on them and finally output results. I am struggling with how to structure the input file in a sane way; that is, in a way that a human can write it easily and a machine can parse it easily. A sample input file made available to me for a similar program is just a stream of comma-separated numbers that don't make much sense on their own, so that's the scenario I am trying to avoid. Though I am giving the details of my particular problem, I am more interested in general input-file structuring strategies. Is a stream of comma-separated values my best bet? Would I be better off using some sort of key:value structure? I don't know much about this, so any help will probably put me in a better track than I am now.

• Ubuntu 12.04 image size 732MB, will it fit a standard CD?

  - by memius

  I have an old computer that can't handle a boot stick install, so i have to create an actual, old fashioned boot CD. However, the image size for Ubuntu 12.04 is 732MB, which is too large for a CD, which can hold only 700MB. The maintainers of Ubuntu 12.04 say the image size will never go over 700MB, and indeed, the download size seemed to be 689MB. Brasero says it won't burn the CD because the file is too big, what's going on?

• Setting up fastcgi on an Ubunutu server (socket file permissions issue)

  - by gray alien

  I am trying to set up mod_fcgid on my server. Part of the requirement is that Apache needs to create a socket file for mod_fcgid. I specified the folder for Apache to write the socket data to: /var/run/apache2/fcgid I then specified this file in my fcgid.conf file as follows: SocketPath /var/run/apache2/fcgid/sock I then changed the owner of the folder to www-data (the apache user) and gave the owner full permissions to the folder and its contents. I was able to run my test fcgi app then. When I rebooted the machine, y fastcgi app no longer worked. After some investigation, I found that ownership of /var/run/apache2/fcgid has been reset to root, and with permission reset to 700 I have the following questions: Is there something specific about the /var/run folder? why is the permissions being reset after a reboot? Should I move my socket file to another location (in case root automatically takes ownership of contents in this folder for security reasons?) I am running Ubuntu 10.0.4 LTS 64 bit

• Can I dynamicaly size a div based on discreet units and still center? [closed]

  - by Dave

  Here's the problem: I have a website I'm working on that, depending on what the user has selected, will pop up a different number of boxes 80px high and 200px wide and currently set to float:left. These boxes are contained within a div that is basically the whole width of the screen minus some 1% margins. So at the moment they all fill in the box and, depending on screen size, occupy a grid of variable height and width. The problem is, if the screen size makes the containing box, say, 700px wide then you end up with 3 boxes per row and a bloody big margin on the right. What I would like to do is center the grid of boxes inside the containing box so that the margins are equal left and right. I suspect this can't be done since it means the containing box needs to set its size by looking both at the size of the user's window as well as the size of its children. It would be easy to do with javascript but I'd prefer not to if that is an option. If it is truly impossible then I will simply script it and let non-js users see a left-justified set of boxes.

• I have a new file type that I would like to handle in gnome how to get file properties?

  - by Mark

  I have a new file type that I would like to handle in gnome. Establishing a new mime type, a new thumbnailer and a new application to display the file type is done. But I need a new tab on the file properties page. This tab is analogous to the tabs for exif information for jpg files or for encoding information for video codecs, that says how long the video is. The files concerned are embroidery files and the file properties needed to be displayed are things like phisical dimentions of the design, how much thread will be used and how many colours. My belief is that with current gnome 3 this is not possible, am I right? Or should I take a wider view that in Ubuntu, anything is possible, just may be a bit difficult?

• How to execute a "name.desktop" file? [duplicate]

  - by Pubudug

  This question already has an answer here: Running a .desktop file in the terminal 10 answers #!/usr/bin/env xdg-open [Desktop Entry] Version=1.0 Type=Link Name=ShareFolder Icon=/usr/share/icons/DPL/NetworkShare.png Name[en_US]=ShareFolder URL=smb://servername/sharefolder This is my .desktop file which has a URL. How do I execute this desktop shortcut in the terminal? If i double click it works perfectly, but I need to execute this in terminal. I tried Running a .desktop file in the terminal. That didn't work for me either but it does if its an "application" shortcut. I'm trying here to execute "link" .desktop file, where you define in the type section (Type=Link) and (URL=smb://servername/sharefolder)

• VCS for single user using file sync service

  - by StackUnder

  I'm trying to setup a version control for my one man project. My project files are in sync thanks to live mesh (but I could be using dropbox for that matter), between my laptop, my home pc and my office pc. I'm now using Netbeans with local file history. Sometimes it helps to revert to a previous state of one file. But imagine a situation when multiple files have problems. Correct me if I'm wrong but I would have to go to every file and revert to previous "safe" state. I don't like this approach, so I'm considering using a version control between SVN and GIT. I have some previous experience with SVN (TortoiseSVN) and I know that I can create a file:// repo. So, what a want to do is setup a VCS inside my synced folder just to have the ability to "revert" to a previous version if something goes wrong. Since everything's been synced to all computers, I wouldn't ever need to run an update. The file tree organization would be the following: C:...\SyncedFolder\MyProject\ Inside MyProject folder are all the project files plus a directory that has SVN or GIT info of my project (the repo/master). What VCS is best for this situation: SVN or GIT? Does SVN need to store all files from HEAD revision, thus "duplicating" all my project inside my synced folder? Does GIT eliminates this problem? Is this the best approach?

• implementing a download manager that supports resuming

  - by Idan K

  hi, I intend on writing a small download manager in C++ that supports resuming (and multiple connections per download). From the info I gathered so far, when sending the http request I need to add a header field with a key of "Range" and the value "bytes=startoff-endoff". Then the server returns a http response with the data between those offsets. So roughly what I have in mind is to split the file to the number of allowed connections per file and send a http request per splitted part with the appropriate "Range". So if I have a 4mb file and 4 allowed connections, I'd split the file to 4 and have 4 http requests going, each with the appropriate "Range" field. Implementing the resume feature would involve remembering which offsets are already downloaded and simply not request those. Is this the right way to do this? What if the web server doesn't support resuming? (my guess is it will ignore the "Range" and just send the entire file) When sending the http requests, should I specify in the range the entire splitted size? Or maybe ask smaller pieces, say 1024k per request? When reading the data, should I write it immediately to the file or do some kind of buffering? I guess it could be wasteful to write small chunks. Should I use a memory mapped file? If I remember correctly, it's recommended for frequent reads rather than writes (I could be wrong). Is it memory wise? What if I have several downloads simultaneously? If I'm not using a memory mapped file, should I open the file per allowed connection? Or when needing to write to the file simply seek? (if I did use a memory mapped file this would be really easy, since I could simply have several pointers). Note: I'll probably be using Qt, but this is a general question so I left code out of it.

• Calculate total batch upload transfer percent with limited information

  - by GONeale

  Hi there, I have a system which uploads to a server file by file and displays a progress bar on file upload progress, then underneath a second progress bar which I want to indicate percentage of batch complete across all files queued to upload. Information and algorithms I can work out are: Bytes Sent / Total Bytes To Send = First progress bar (eg. 512KB of 1024KB (50%)) That works fine. However supposing I have two other files left to upload, but both file sizes are unknown (as this is only known once the file is about to commence upload, at which point it is compressed and file size is determined) how would I go about making my third progress bar? I didn't think this would be possible as I would need "Total Bytes Sent" / "Total Bytes To Send", to replicate the logic of my first progress bar on a larger scale, however I did get a version working: "Current file number we are on" / "total number of files to send" returning the percentage through the batch, however obviously will not incrementally update and it's pretty crude. So on further thinking I thought if I could incorporate the current file % with this algorithm I could perhaps get the correct progress percentage of my batch's current point. I tried this algorithm, but alas to no such avail (sorry to any math heads, it's probably quite apparent why it won't work) ("Current file number we are on" / "total number of files to send") * ("Bytes Sent" / "Total Bytes To Send") For example I thought I was on the right track when testing with this example: 2/3 (2nd of 3rd file) = 66% (this is right so far) but then when I added * 0.20 (for indicating only 20% of 2nd file has uploaded) we went back to 13%. What I need is only a little over 33%! I did try the inverse at 0.80 and a (2/3 * (2/3 * 0.2)) Can this be done without knowing entire bytes in batch to upload? Please help! Thank you!

• Force Download Files Broken Headers wrong?

  - by Sinan

  if($_POST['mode']=="save") { $root = $_SERVER['DOCUMENT_ROOT']; $path = "/mcboeking/"; $path = $root.$path; $file_path = $_POST['path']; $file = $path.$file_path; if(!file_exists($file)) { die('file not found'); } else { header("Cache-Control: public"); header("Content-Description: File Transfer"); header('Content-Type: application/force-download'); header("Content-Disposition: attachment; filename=\"".basename($file)."\";" ); header("Content-Length: ".filesize($file)); readfile($file);}} As soon as i download the file and open it i get an error message. When i try to open a .doc i get the message : file structure is invalid. And when i try to open a jpg : This file can not be opened. It may be corrupt or a file format that Preview does not recognize. But when i download PDF files, they open without any problem. Can someone help me? P.s. i tried different headers including : header('Content-Type: application/octet-stream');

• Read/Write Files from the Content Provider

  - by drum

  I want to be able to create a file from the Content Provider, however I get the following error: java.io.Filenotfoundexception: /0: open file failed: erofs (read-only file system) What I am trying to do is create a file whenever an application calls the insert method from my Provider. This is the excerpt of the code that does the file creation: FileWriter fstream = new FileWriter(valueKey); BufferedWriter out = new BufferedWriter(fstream); out.write(valueContent); out.close(); Originally I wanted to use openFileOutput() but the function appears to be undefined. Anyone has a workaround to this problem? EDIT: I found out that I had to specify the directory as well. Here is a more complete snippet of the code: File file = new File("/data/data/Project.Package.Structure/files/"+valueKey); file.createNewFile(); FileWriter fstream = new FileWriter(file); BufferedWriter out = new BufferedWriter(fstream); out.write(valueContent); out.close(); I also enabled the permission <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" /> This time I got an error saying: java.io.IOException: open failed: ENOENT (No such file or directory)

• PHP: parse $_FILES[] data in multidimesional array

  - by superUntitled

  I having been looking around for an answer to this and have not found an answer anywhere, I am hoping someone has done this before! I have a form that allows for dynamic duplication of the form fields. The form allows for file uploads and text input, so the data is sent in both $_POST and $_FILES arrays. The the initial set of inputs look like this: <input type="text" name="primary[1][text]" /> <input type="file" name="primary[1][file]" /> <input type="text" class="a" name="secondary[1][text][]" /> <input type="file" name="secondary[1][file][]" /> When duplicated the fields are incremented, they look like this: <input type="text" name="primary[2][text]" /> <input type="file" name="primary[2][file]" /> <input type="text" class="a" name="secondary[2][text][]" /> <input type="file" name="secondary[2][file][]" /> To complicate matters, the "secondary" form fields can also be duplicated (thus the [] at the end of the secondary name array. How can I parse the posted $_FILES array? I have tried something like this: foreach ($_FILES['question'] as $f_num) { echo $f['file']['name']; } but I get an "Undefined index: file... " error.

• Log4net RollingFileAppender Size rollingStyle file extension

  - by BrettRobi

  I am using the RollingFileAppender and the Size rollingStyle. By default it creates backup files with a numbered extension, this drives me nuts. Is it possible to change it so it always uses a defined extension (say .txt or .log) and inserts the number as part of the file name. For example: myapp.log myapp.1.log myapp.2.log myapp.3.log Here is my current configuration: <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="myapp.log"/> <appendToFile value="true"/> <rollingStyle value="Size"/> <maximumFileSize value="1MB"/> <maxSizeRollBackups value="10"/> <staticLogFileName value="true"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date{ISO8601} [%3thread] %-5level %logger{3}: %message%newline" /> </layout> </appender>

• SSIS 2008 Rows per batch and Maximum insert commit size

  - by Nissan Fan

  I've got about 100 million rows that I'm moving in SSIS 2008 via a Data Flow Task. It's pretty much a straight table data copy using a Multicast. My question is this: Using the OLE DB Destination Editor I have two options: Rows per batch and Maximum insert commit size. What are good settings for this? I've only been able to find that you are recommended to set Maximum insert commit size to 2147483647 instead of 0, but then tweak both these settings based on testing. I'm curious to find out if anyone has discovered anything useful in their own management of these values.

• Binding the position and size of a UserControl inside a Canvas in WPF

  - by John

  Hi. We have dynamically created (i.e. during runtime, via code-behind) UserControls inside a Canvas. We want to bind the position (Canvas.Left and Canvas.Top) and width of those sizable and draggable UserControls to a ObservableCollection<. How would we achieve this if the Usercontrol is contained in a DataTemplate which in turn is used by a ListBox whose DataContext is set to the collection we want to bind to? In other words, how do we bind a control's position and size that doesn't exist in XAML, but in code only (because it's created by clicking and dragging the mouse)? Notice that the collection can be empty or not empty, meaning that the size and position stores in a collection item must be correctly bound to so that the UserControl can be sized and positioned correctly in the Canvas - via DataBinding. Is this possible?

• VBA ActiveX controls grow in size over Remote Desktop Connection

  - by Alistair Knock

  We have an Excel workbook with a number of ActiveX controls, running in Excel 2003 on Windows XP. When connecting using Remote Desktop, the ActiveX controls change font, sometimes font size, and sometimes orientation (in the case of a spinner control). This happens on first connection and also as the workbook is used - some of the controls then enlarge in size, often overlapping other controls and part of the workbook. I read somewhere this may be caused by improper connection management (not closing them) leading to increasing memory usage; are there other reasons why the display is so different over Remote Desktop and are there workarounds? (the properties of each control usually remain the same, so force-resizing them doesn't always have an effect)
