• Mercurial hg clone error - "abort: error: Name or service not known"

  - by Bojan Milankovic

  I have installed the latest hg package available for Fedora Linux. However, hg clone reports an error. hg clone http://localmachine001:8000/ repository reports: "abort: error: Name or service not known" localmachine001 is a computer within the local network. I can ping it from my Linux box without any problems. I can also use the same http address and browse the existing code. However, hg clone does not work. If I execute the same command from my Macintosh machine, I can easily clone the repository. Some Internet resources recommend editing .hgrc file, and adding proxy to it: [http_proxy] host=proxy:8080 I have tried that without any success. Also, I assume that proxy is not needed in this case, since the hg server machine is in my local network. Can anyone recommend me what should I do, or how could I track the problem? Thank you in advance.

• in TFS can we customize the merge algorithm (conflict resolution)

  - by Jennifer Zouak

  In our case we want to igonore changes in code comment headers for generated code. In Visual Studio, we can change the merge tool (GUI that pops up) and use a 3rd party tool that is able to be customized to ignore changes (http://msdn.microsoft.com/en-us/library/ms181446.aspx). Great, so a file comparison no longer highlights code comments as differences. However when it comes time to checkin, the TFS merge algorith is still prompting us to resolve conflicts. Is there any way to better inform the merge conflict resolution algorithm about which changes are actually important to us? Or can we replace the algorithm or otherwise have it subcontract its work to a 3rd party?

• Defining Form Input with Dialog

  - by Workoholic

  Hi. I want my php application to allow the user to select a file from their computer. I then want to store the file's path, but I don't want to upload the file. With the <input type="file" />, the file is uploaded, which would take too long. Is there a way to do this? Maybe if I change the input's type to text with jquery right before the form is sent? I could just let the user type the path, but that is not very convenient...

• mingw32-make : "Input line too long" issue

  - by hjsblogger

  We have a Makefile which runs on a Windows 2003 machine and we are using mingw32-make for it. Since the Makefile has many include paths, it exceeds the buffer size of 8K that the cmd can handle [Ref - http://support.microsoft.com/kb/830473/EN-US/due to which the compilation results in "input line too long" issue. I wanted to know the following - What would be the best way to optimize the Makefile as I have already removed unwanted compiler switches, include paths etc. Is there any way we can put all the INCLUDE paths in one .txt file and import it in the Makefile.I could not find any mingw32 documentation for the same. Any other inputs/hints/reference links are most welcome. Thanks, -HJSblogger

• How to walk through two files simultaneously in Perl?

  - by Alex Reynolds

  I have two text files that contain columnar data of the variety position-value. Here is an example of the first file (file A): 100 1 101 1 102 0 103 2 104 1 ... Here is an example of the second file (B): 20 0 21 0 ... 100 2 101 1 192 3 193 1 ... Instead of reading one of the two files into a hash table, which is prohibitive due to memory constraints, what I would like to do is walk through two files simultaneously, in a stepwise fashion. What this means is that I would like to stream through lines of either A or B and compare position values. If the two positions are equal, then I perform a calculation on the values associated with that position. Otherwise, if the positions are not equal, I move through lines of file A or file B until the positions are equal (when I again perform my calculation) or I reach EOF of both files. Is there a way to do this in Perl?

• How can I hide tracing code in Visual Studio IDE C# ?

  - by Mark

  As I'm starting to put more tracing in my code, i'm realizing it adds a lot of clutter. I know Visual Studio allows you to hide and reveal code, however, i'd like to be able group code into "tracing" code and then hide it and reveal at will as i'm reading the code. I suppose it could do this either per file or per class or per function. Is there any way to do this? What do you guys do? Adding some clarification The hide current feature kind of allows you to do this except that when the code is hidden, you can't tell if its tracing or not. You also can't say "hide all tracing code" and "reveal all tracing code" which is useful when reading a function depending on what you are trying to do.

• Regexp to extract sources from different video embeds

  - by Ben

  My SMF forum contains posts with video and I want to extract them to show on the Wordpress main page. My current regexp (thanks to SO!) extracts the url of the videos, which I embed using AutoEmbed. Everything works up until a post looks like this: <embed height="600" width="600" allowscriptaccess="never" quality="high" loop="true" play="true" src="http://mmavlog.net/embed/player.swf?file=http://video.ufc.tv/CSG/UFC113/20100507_ufc113_weigh_in_400k.flv" type="application/x-shockwave-flash"> Here is my current regexp: $regexp = "/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i"; Since the posts can contain <embed> or <object> I realize that looking for the url by the "http" might be inaccurate. How can I use the regexp to look for "src=" for <embed> and "data=" for <object>?

• Download and write .tar.gz files without corruption.

  - by arbales

  I've tried numerous ways of downloading files, specifically .zip and .tar.gz, with Ruby and write them to the disk. I've found that the file appears to be the same as the reference (in size), but the archives refuse to extract. What I'm attempting now is: Thanks! def download_request(url, filePath:path, progressIndicator:progressBar) file = File.open(path, "w+") begin Net::HTTP.get_response URI.parse(url) do |response| if response['Location']!=nil puts 'Direct to: ' + response['Location'] return download_request(response['Location'], filePath:path, progressIndicator:progressBar) end # some stuff response.read_body do |segment| file.write(segment) # some progress stuff. end end ensure file.close end end download_request("http://github.com/jashkenas/coffee-script/tarball/master", filePath:"tarball.tar.gz", progressIndicator:nil)

• What is the easiest way to loop through a folder of files in C#?

  - by badpanda

  I am new to C# and am trying to write a program that navigates the local file system using a config file containing relevant filepaths. My question is this: What are the best practices to use when performing file I/O (this will be from the desktop app to a server and back) and file system navigation in C#? I know how to google, and I have found several solutions, but I would like to know which of the various functions is most robust and flexible. As well, if anyone has any tips regarding exception handling for C# file I/O that would also be very helpful. Thanks!!! badPanda

• After tar extract, Changing Permissions

  - by Moe

  Just a Question Regarding unix and PHP today. What I am doing on my PHP is using the Unix system to untar a tarred file. exec("tar -xzf foo.tar.gz"); Generally everything works fine until I run into this particular foo.tar.gz, which has a file system as follows: Applications/ Library/ Systems/ After running the tar command, it seems that the file permissions get changed to 644 (instead of 755). This causes Permission denied (errno 13) and therefore disabling most of my code. (I'm guessing from lack of privileges) Any way I can stop this tar command completely ruining my permissions? Thanks. Oh and this seems to only happen when I have a foo.tar.gz file that Has this particular file system. Anything else and I'm good.

  - by ajsie

  there are plenty of frameworks for coding MVC web applications. this time im going to code a library (think of Doctrine or Solr) with a bunch of class files. u just include a bootstrap or a class file and you are ready to use my classes. i have never tried to code a library before and intend to code one for learning purpose so that i can use various design patterns i have learned. are there any great frameworks for this, how i should organize the different class files, where i can put configuration files and so on? tutorials or other information would be great too. thanks

• Split text files Accross threads

  - by Kevin

  The problem: I have a few text files (10) with numbers in them on every line. I need to have them split across some threads I create using the pthread library. these threads that are created (worker threads) are to find the largest prime number that gets sent to them (and over all the largest prime from all of the text files). My current thoughts on solutions: I am thinking myself to have two arrays and all of the text files in one array and the other array will contain a binary file that I can read say 1000 lines and send the pointer to the index of that binary file in a struct that contains the id, file pointer, and file position and let it crank through that. a little bit of what I am talking about pthread_create(&threads[index],NULL,calc_sqrt,(void *)threadFields[index]);//Pass struct to each worker Struct: typedef struct threadFields{ int *id, *position; FILE *Fin; }tField; If anyone has any insight or a better solution it would be greatly appreciated Thanks

• Copying files from one directory to another in Java

  - by user42155

  Hello, I want to copy files from one directory to another (subdirectory) using Java. I have a directory, dir, with text files. I iterate over the first 20 files in dir, and want to copy them to another directory in the dir directory, which I have created right before the iteration. In the code, I want to copy the review (which represents the ith text file or review) to trainingDir. How can I do this? There seems not to be such a function (or I couldn't find). Thank you. boolean success = false; File[] reviews = dir.listFiles(); String trainingDir = dir.getAbsolutePath() + "/trainingData"; File trDir = new File(trainingDir); success = trDir.mkdir(); for(int i = 1; i <= 20; i++) { File review = reviews[i]; }

• explain this macro

  - by deostroll

  #define __T(x) L ## x Found in code from one of the MFC source header file. It is mostly used for converting strings to ........ (I don't know what). If I am correct it converts strings to LPCTSTR...don't know what that type is either... I can't seem to convert char* into LPCTSTR. While MFC file handling, the following code will always return error while trying to open the file... char* filepath = "C:\\Program Files\\Microsoft Office\\Office12\\BITMAPS\\STYLES\\GLOBE.WMF"; if( !file.Open((LPCTSTR)filepath , CFile::modeRead, &fexp) ) { fexp.ReportError(); return 1; } But instead if I wrote it this way, it doesn't give error: if( !file.Open( _T("C:\\Program Files\\Microsoft Office\\Office12\\BITMAPS\\STYLES\\GLOBE.WMF") , CFile::modeRead, &fexp) ) { fexp.ReportError(); return 1; } I am looking at passing a variable as the first argument to the CFile::Open() method.

• Unable to remove file using 'rm'

  - by Alvin Sim

  Hi all, In one of our severs (IBM AIX), we have a file in path /data/1002/ which we were not able to remove or delete using the 'rm' command. The error message we got is "rm: A1208001.002: A file or directory in the path name does not exist." With the "-f" option, no error message was displayed, but the file is still there. This file has a '0' byte size and when i use the command "touch A120001.002", i see two files with the same file name in that directory. The directory listing is as below: $ ls -l total 56 -rwxrwxrwx 1 oracle dba 0 Feb 09 11:57 S1208001.002 drwxrwxrwx 4 nobody dba 24576 Feb 09 13:36 backup How do I remove this bogus fie? Thanks.

  I want to add a file hstest.c which comes with bluez package but not by default added to the makefile to the sources that are compiled with the buid system. I read about makefiles and autotools but now I am hesitant to make changes to the makefiles. Should I modify the makefile.am and then run automake or just change the makefile.in or the makefile itself ? and how ? config script Makefile.am Makefile Makefile.in

• bash command for each file in a folder

  - by Robert

  I have a set of files on which I would like to apply the same command and the output should contain the same name as the processed file but with a different extension. Currently I am doing rename /my/data/Andrew.doc to /my/data/Andrew.txt I would like to do this for all the .doc files from the /my/data/ folder and to preserve the name. I tried several versions but I guess I have something wrong in the syntax as I an new to linux.

• Does SCP lock the file it is transfering?

  - by thadon

  Have a situation where we have an application log sitting out on an AIX server. The log is being continually written to from the application, and we have users on Windows who want to view the file. What they've been doing is using WinSCP to transfer the file to their desktop and they open it using a text editor. What I think might be happening is scp is locking the file for the duration of the transfer, and the application ceases to be able to write to the file. The reason I believe this is the log file will stop growing at random points during the day. Is that what perhaps is going on?

• How to stop Excel 2003 from loading a Gazillion files

  - by Gary M. Mugford

  One of my soon-to-be-ex-friends got an Excel file from another friend of his and decided to click on it. It started opening all kinds of files from within Excel. Over 200 and still counting when he called me. I told him to go to task manager, which showed a LOT of files in the applications tab, but only one Excel.exe in the processes tab. Closing it down there, closed down Excel. I then CrossLooped in to see if I could give him a helping hand. Each time Excel was re-opened, the mass influx of files started. They were all kinds of files, PDFs, Docs, JPGs, even some spreadsheets. It looked like the end of solitaire, with multiple windows opening (XP) and the counter on the lone Excel button on the task bar counting off the files. I did the task manager exit routine and went looking for temp files. I CrapCleaned out the system. Made sure I went through the files created in the last hour and deleted anything with a temp anywhere in it. I also deleted the crappy infected/corrupted file from it's place on the desktop (yeah, I know, I yelled for 15 minutes on THAT subject). Despite a delousing, the restart of Excel, which complained of a deactivated add-in, would start the cascading windows, whether I answered yes or no to that question. Yes, it knew it had a serious crash, but why would it just keep on trying to load the bad file, even when I got rid of it? But here's the real question. WHERE was it loading from? I went through the backup folder and NOTHING was there! So what's the process for starting Excel WITHOUT it trying to do a crash recovery? Sort of makes me feel stupid at times. Thanks for any light you can shed on this issue. GM

• Chunking large rsync transfers?

  - by Gabe Martin-Dempesy

  We use rsync to update a mirror of our primary file server to an off-site colocated backup server. One of the issues we currently have is that our file server has 1TB of mostly smaller files (in the 10-100kb range), and when we're transferring this much data, we often end up with the connection being dropped several hours into the transfer. Rsync doesn't have a resume/retry feature that simply reconnects to the server to pickup where it left off -- you need to go through the file comparison process, which ends up being very length with the amount of files we have. The solution that's recommended to get around is to split up your large rsync transfer into a series of smaller transfers. I've figured the best way to do this is by first letter of the top-level directory names, which doesn't give us a perfectly even distribution, but is good enough. I'd like to confirm if my methodology for doing this is sane, or if there's a more simple way to accomplish the goal. To do this, I iterate through A-Z, a-z, 0-9 to pick a one character $prefix. Initially I was thinking of just running rsync -av --delete --delete-excluded --exclude "*.mp3" "src/$prefix*" dest/ (--exclude "*.mp3" is just an example, as we have a more lengthy exclude list for removing things like temporary files) The problem with this is that any top-level directories in dest/ that are no longer present present on src will not get picked up by --delete. To get around this, I'm instead trying the following: rsync \ --filter 'S /$prefix*' \ --filter 'R /$prefix*' \ --filter 'H /*' \ --filter 'P /*' \ -av --delete --delete-excluded --exclude "*.mp3" src/ dest/ I'm using the show and hide over include and exclude, because otherwise the --delete-excluded will delete anything that doesn't match $prefix. Is this the most effective way of splitting the rsync into smaller chunks? Is there a more effective tool, or a flag that I've missed, that might make this more simple?

• How can I remove UNC password from a file

  - by freddoo

  Hi we have an mp4 file on our web server in a virtual directory When we try to access the file we get prompted for a username/password. When I tried to change the path of the virtual directory I got the message 'The following child nodes also define the value of the "UNCPassword" property, which overrides the value you have just set ...' which included the mp4 file that we try to access. How can I remove the UNC Password securing the file? The file is not on a shared drive its on the same drive as the web site root. The funny thing is the path of the virtual directory is not a UNC path it's a full path on the same server d:.....
