Does NSFileHandle manage a file descriptor
NSPipe * write = [NSPipe pipe];
NSFileHandle * writeHandle = [write fileHandleForWriting];
I know what the above does and how to use it, I just don't like using something without know 100% how it works. So just to clarify, does "[write fileHandleForWriting];" return a file descriptor that "writeHandle" manages or is it something more complex with Obj -C?

Yes. It is a plain file handle made more complex with an Objective-C wrapper.

Problem with file descriptors not released by JMF
Hi,
I have a problem with file descriptors not released by JMF. My application opens a video file, creates a DataSource and a DataProcessor and the video frames generated are transmitted using the RTP protocol. Once video transmission ends up, if we stop and close the DataProcessor associated to the DataSource, the file descriptor identifying the video file is not released (checkable through /proc/pid/fd). If we repeat this processing once and again, the process reaches the maximum number of file descriptors allowed by the operating system.
The same problem has been reproduced with JMF-2.1.1e-Linux in several environments:
- Red Hat 7.3, Fedora Core 4
- jdk1.5.0_04, j2re1.4.2, j2sdk1.4.2, Blackdown Java
This is part of the source code:
// video.avi with tracks audio(PCMU) and video(H263)

Many thanks.Its a bug on H263, if you test it without h263 track or with other video codec, the release will be ok.
You can try to use a not-Sun h263 codec like the one from fobs or jffmpeg projects. -
How to determine which file descriptor opened my driver?
Suppose a user process opens my driver twice. How does open() determine which file descriptor opened the device? In Linux, the kernel will pass a pointer to a structure which represents the open file descriptor. However, Solaris only passes the device number to open(), so I can only determine my device was opened, but not which file. I need this information because my driver needs to keep track of all file descriptors opened for the device.
Thanks!
-DarrenI'm still at a loss why you need to know the file descriptor value (unless the app is sufficiently spaghettied that it has to query the driver to figure out what it opened with what). It's like asking what filename was used to open the device (which you can't get either). Since Solaris is based on a Streams framework, it would be bad to have drivers to even think it has a direct mapping into user space. It would be the same in asking (using /bin/sh):
prog3 4>&1 3>&1 2>&1 | prog2 | prog1
and you want to know from prog1 what descriptor prog3 wrote to. I don't see how linux even does this properly, since any given file open can have multiple file descriptors (via dup). -
SMC - "The management domain file...does not exist"
Hi All,
Just a quickie to see if anyone has seen this and has any pointers to getting out of it...
Solaris 10 u5 x86. Machine has got SRSS4.0 running on it, the only other modification is CUPS is running in favour of the Solaris lp stuff (got instructions for this off a BigAdmin article).
Anyways, I use SMC to manipulate user/group stuff on the local machine. SMC launches just fine, and I can gather System Information, view logs, disk configuration, processes etc. However, when attempting to do any user/group/role stuff management, I authentication with root role, click on the relevant panel, and get this:
"The management server cannot perform the operation requested.
If this problem persists, refer to the Log Viewer for additional information and contact your Sun Microsystems support provider.
The actual error reported was:
The management domain file:/shadowfire/127 does not exist or cannot be managed on server shadowfire."
The behaviour is consistent. Gee, it was running fine before, AFAIK...
Any pointers to what may have come unstuck gratefully appreciated, as always :)
DaveI came across the same problem late July almost same day - on a brand new M4000 server with Solaris 10. I use an X-windows client to connect in and open Common Desktop Environment as "root". Then when I invoke SMC it works for everything except trying to open User Maintenance - then I get the error above.
I came across something quite by accident whilst I was being advised to make edits to /etc/hosts (which I dont think made a difference anyway so I wont mention them)
If I use my X-Windows client and open Common Desktop Environment as an ordinary user (say "joe") - then invoke SMC from the menu - when asked by the SMC utility to provide a logon then (as you would) enter the root username and password, guess what ! - I could open the User Maintenance icon without the error appearing and make changes and save them.
Funny how a less privileged user than root invoking CDE seems to provide a basis to get the option to work! I still get the error by using CDE as root
Wanna Try it? -
Increase file descriptor limits on managed server
Hi,
we have an Admin Server which manages a managed server.
We need to increase file descriptor limits of managed server.
We modified the script commEnv.sh on Admin server and we successfully increased to 65,536 the limit. Here is the log of the boot of Admin Server
####<Sep 25, 2013 11:04:18 AM CEST> <Info> <Socket> <lv01469> <AdminServer> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1380099858592> <BEA-000416> <Using effective file descriptor limit of: 65,536 open sockets/files.>
How can we do the same thing on managed server. We tried to modify the same script (commEnv.sh) on managed server but the file descriptor limits is still 1,024.
####<Sep 25, 2013 11:23:30 AM CEST> <Info> <Socket> <lv01470> <119LIVE_01> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1380101010988> <BEA-000415> <System has file descriptor limits of - soft: 1,024, hard: 1,024>

It was necessary restart Node Manager after modify the commEnv.sh. -
Latest version of Lightroom will not download RAW files from my D750. How does one get around this? Bought Lightroom for it's ability to manage RAW files and now very disappointed.
Here is the contents of a batch file which will convert whatever raws you drop on it:
"C:\Program Files (x86)\Adobe\Adobe DNG Converter" -cr7.1 -dng1.4 -p0 %*
Once you download the latest converter (release candidate from adobe labs, if necessary), and save the appropriate contents of the batch file (change path to match your system, and parameters to match your druthers, if applicable), the procedure is:
1. Drop raw files on bat file.
2. Import as usual (the DNGs).
Not too bad once you're set up (if DNG converter supports your raws).
Documentation:
http://wwwimages.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/dng_commandline.pd f
Note: on Mac, you may need to use "$@" (with the double-quotes) instead of %* (which is dos batch syntax), and you will need to use the full path to the converter executable file, e.g.
“/Applications/Adobe DNG Converter.app/Contents/MacOS/Adobe DNG Converter”
If too much, just use the GUI instead of the bat file.

Hello I am running Windows 8 Single Language Edition.
I tried to Make a NAS folder available offline by right clicking on the folder. But "Make Available Offline" option is missing.
Then went to Control Panel->Sync Centre clicking "Manage offline files" does nothing.
How to fix my issue?
Thanks,
Simon MandyHi Simon,
Regarding to this issue, please refer to this article:

Sudden increase in open file descriptors
Our system is live since an year and half and for the first time I encountered the following exception
"java.net.SocketException: Too many open files"
When our internet application stopped responding I immediately checked the number of open file descriptors on my Solaris machine by using the "lsof" command and found that it was an abnormal 600 value and as I continued monitoring it reached 1024 in matter of minutes and WebLogic gave the above exception. The current setting for file descriptors is 1024. But all these days the average number of open file descriptors was well below 220.
I also took thread dumps and found that most of the threads were stuck at the following location

There is no file descriptor leak in the application. My question is since all the threads are hung at JDBC and socket level, does it mean that a faulty query would have triggered this problem(may be the database was too busy executing a faulty query).
I suspect this because I recieved a database exception soon after the problem appeared. One of my database insert transaction had timed out after 300 seconds. Also this was the first time I recieved this kind of an exception

Hi,
I am using WebLogic 8.1 SP2 on a Solaris machine.Ok, good enough. Once WebLogic times out a transaction, it rolls it back on the
connection. That Sybase driver's rollback doesn't unfortunately affect it's
own running statements. For 81sp3 we added code to explicitly cancel any ongoing
statement during a rollback. This may be what you need to free up those
threads and the socekts the driver may be keeping open. If you can upgrade
to a newer version of 8.1, this code will free you up. Alternately, you can
try either upgrading to Sybase'e latest driver or to our BEA driver for Sybase.
Ask support for the latest BEA driver package for 8.1.

Raghu -
Open/Save Dialog does not show new files?
Say you are working on a logic file in a folder and you have
a few audio and movie files in that folder, and you launch
Logic and via the open/save dialog window you add a few
files to your song and in that dialog window you can see
all the files in that folder.
Then, in the Finder you add a few more files and movies to
that folder and again use the open/save dialog window to
add more files BUT the new files you added since launching
logic are NOT SHOWN in the dialog window ! ?
What's the deal with that?
Every other app can show files added since the launch of the
application, why not Logic?
PowerBook G4 1GHz Mac OS X (10.3.9)project manager
um, yeah.
Should not need the project manager simply to see new files added to a directory in a Open/Save dialog window since last opening the app.
I did a scan, a extended scan, opened all the little turn down arrows of the
full path to the directory I knew there to be the new files and yes, Logic
shows them there in the "Project manager".
BUT Logic still does not show the files in the Open/Save dialog windows.
This is strange because even simple app like TextEdit can show
new files in it's Open/Save dialog function windows without the need of
a project manager.
I have to quit and re-launch each time to see any new files? -
Sorry this is the 1st time and I don't know what to do. I have lost the ability to manually manage my music/video files. After upgrading it worked for a few days as I was adding music to my phone. After 2 days, I couldn't anymore. I have windows 7 ultimate 32, iTunes 11, and iPhone 4 on 6.0.1. With the iPhone connected, under the summary page, manually manger is clicked. iTunes Match is off in iTunes and on phone. I have uninstalled and reinstalled. Copied my media back into the media folder. I have also done a factory reset and restored from back up and still can't add music manually. All my music is stored on an external be aide the media folder is in the primary hard drive. I can try adding to the iTunes library and add that way without manually adding each song but I feel that defeats the purpose. I'm in contact with individual DJs that make their own music and yes it is sold intubes and that was never the issue before. I will do a factory reset on the phone, so a clean install of 11 again and just add my apps back but I don't know what else to do. Also, I am only using one computer to manage my files and it is the only computer authorized for my phone. There is no other computer! I am open to any ideas.
Thank you in advance
Caliph3001. - krusade.netUpdate:
I mean that the dj's create their own music and the music isn't sold in iTunes. Also, I have done the factory reset clean, installation of Itunes 11 (*lost all of my apps - yeah the back up i have didn't have all the apps or they are read as apps but said that they are missing - redownloading them now the ones that can be retrieved now) and it still gives me the black "no" arrow when trying to drag and drop - but I have figured that I would just copy the files into the main library, but it defeats the purpose of having an external with all my files. Is there away to get iTunes to recognize my hd as the library? A new issue developed, it kept saying that it was connected to another library and to connect it would have to erase everything on the phone so I agreed. And it seems to be fine now besides the copy and paste. I have added a few more issues that risen since this began below.
A few more questions:
After a clean installation: I have lost most of the paid apps. Does Itunes back up a history or was it stricly on my computer? Some of these were paid apps and I dont want to have to purchase them again. There should be something connected to your name within the store account that stores all the purcchase you have made and allow you to redownload them as in the playstation network. Also, how do people retrieve lost apps if the only back up was on their computer that crashed? Is there any to get Itunes to recognize my external HD as a library of my music? -
How can I STOP iTunes from automatically trying to add podcasts to my iPod when I plug it in and sync it, so I can manage the files? I have already unchecked "Sync Podcasts" and "Automatically include,"yet EVERY time I sync it,it still transfers podcasts as the last step, and at other times randomly, when trying to just add some MP3's to a playlist, for example. I can't seem to find any other option to uncheck, and can't find an answer from my so-far internet searching.
erict, you blew me away with that suggestion! It was something so simple I couldnt believe I hadnt thought of it! But in the end it didn't work, which I was really surprised about. On Windows anytime anything was moved itunes was hoplessly lost, but on this mac it still kept up with everything. I tried renaming folders, moving folders, and even renaming moved folders but it still kept trying to import.
I even went as far as deleting EVERYTHING i had moved to the Mac, which didnt really work. It still kept trying to import what wasnt there which made it continue to freeze up. However, after doing this it, the freezing was not nearly as bad. It gave me enough of a break to cancel it through the itunes dialog box at the top of the app. So in the end, thats all I really needed to do, only before I had deleted everything the freezing would not allow me to do it.
So now Im reimporting everything again, only slowly, and only a few Artists at a time. -
Bad File Descriptor in /dev/fd/3, and 94Gb of disk space missing
I noticed a few days ago, possibly as the result of a recent kernel panic, that I have a large chunk of hard drive space missing. The Finder reports that I have approximately 89Gb of free space, but using "df" reports that there is approximately 178Gb free. Using "du" doesn't report any unexpected huge files, so I tried running GrandPerspective. In addition to the usual file usage and free space, this shows a single 94Gb block of "miscellaneous used space".
I then booted into Single User mode to run fsck on the startup drive. This reported several errors, and took 3 passes to repair the directory structure, but didn't recover the missing space. I have subsequently run TechTool Pro and DiskWarrior on the startup drive (both of which found various minor errors), but the 94Gb still refuses to show itself.
I then tried using "find" to look for single large files, using "sudo find / -size +94371840" (anything larger than 90Gb), and I get the following errors:
find: /dev/fd/3: Bad file descriptor
find: /dev/fd/4: Not a directory
find: /dev/fd/5: Not a directory
After searching Google, a "Bad file descriptor" error points to an inode issue, that fsck cannot fix, but I don't know enough (read: anything) about inodes to risk running the clri command to zero the problem inode.
Short of blanking the startup disk and installing from scratch (not an attractive option), is there anything I can do to fix the broken inode and recover the missing space?
Any help appreciated.Drawing Business wrote:

This is not an error and always happens with find unless you exclude the /dev hierarchy from the search. (Interestingly this seems to have gone away with 10.5??)
To locate your missing space, try WhatSize. Another alternative which I have not used personally is Disk Inventory X.
As an additional point, with 10.4 it is actually better to use Disk Utility, since it does more than fsck: Resolve startup issues and perform disk maintenance with Disk Utility and fsck, quote:
Note: If you're using Mac OS X 10.4 or later, you should use Disk Utility instead of fsck, whenever possible. -
Where is the file descriptor leak in this code?
The following "appendStringToFile" method is used to append a String to a file. My java app calls this method a few times per minute, and then crashes after running for about 12 hours. The exception is "Too many open files". The code that calls it does so from a synchronized block, so concurrency is not the problem, and it would seem that only one file descriptor should be used at a time.
Can anyone find the problem?
public static void createParentDirectoryIfNeeded(String path) {
String dirPath = path.substring(0, path.lastIndexOf('/'));
File dir = new File(dirPath);
if (!dir.exists()) {
dir.mkdirs();
public static void appendStringToFile(String s, String path) {
FileWriter fileWriter = null;
try {
createParentDirectoryIfNeeded(path);
// create file if it doesn't already exist
File file = new File(path);
file.createNewFile();
if (s != null) {
fileWriter = new FileWriter(file, true);
fileWriter.write(s.toCharArray());
} catch (IOException ioe) {
ErrorHandler.handleError(ioe, LOG);
} finally {
if (fileWriter != null) {
try {
fileWriter.close();
} catch (IOException ioe) {
ErrorHandler.handleError(ioe, LOG);

Edited by: mikewertheim on Sep 26, 2008 11:56 AMI don't know what is causing your problem but I can suggest several improvements.
1) Given a file 'f' then one can create the parent directory using f.getParentFile().mkdirs();so that one does not need to useString dirPath = path.substring(0, path.lastIndexOf('/')); 2) There is not need to test if the directory exists before creating it. If it exists then f.getParentFile().mkdirs(); will just do nothing.
3) There is no need to usefile.createNewFile();because if the file does not exist then fileWriter = new FileWriter(file, true);will create it. -
Until the last month or so, I've used a powermac G5 as my computer. Now that I've added a shiny new MBP with a 750 gb drive, I'm having all the normal growing pains that come with such. Amazed with the speed boost, having to learn to deal with big time limitations on storage.
Right now, I'm trying to figure out managing movie files. Up until now, I upload most if not all my movie files from my iPhone or Canon 7d into iPhoto. Then later, open iMovie and it "sees" them and does what it does and so forth. Basically, I was using iPhoto and iMovie to handle movie files.
Now that I'm using a MBP, I don't know that I'm going to continue using the powermac G5. Not much, anyways. The speed is way to amazing with the MBP. Not only that, I'm using Aperture 3 for managing pics and it happens to upload videos. I posted in the Ap3 community a similar question regarding managing movies with my current setup.
Should I turn off the import movies option for Ap3 and only use iMovie to continue to manage movie files?
considering movie files, which are primarily HD ones for me now, I have iPhoto, iMovie, and now Ap3 that I can import movies to. If i were using a big desktop macPro with tons of HD space, I really wouldn't think much about hard drive space.
However, now that I'm entering the world of laptop computing for the first time, managing disk space (as you all know) is a specialty all its own, I'm learning quickly. As far as Aperture is concerned, I referenced all my masters off the HD inside the MBP onto an external drive so I can free up some space. I freed up almost 400 gbs!
Now I'm looking at how to manage movie files on a MBP.
Real world example: went to a concert last night, filmed over 2 hours of movie files of the concert. Before I import them off my iPhone, I'm wondering where in the world to import them to. iPhoto? iMovie? Ap3?
What do you all suggest I do with a MBP and managing movie files? Should I continue with importing to iPhoto and letting iMovie then "see" them and do it's thing? Or should I get another external FW800 drive and start using it just for movie files?
What would you long term users of laptops suggest as the best long term approach to managing movie files (which program, internal Vs external, etc) on a macbookpro?
ThanksIt won't take too much time for your hard drive to fill up with movies you've processed through Aperture or iMovie. Many users opt to dedicate an external hard drive for their movie projects, and I can recommend the G-Drive and Seagate Go Drive for speed and reliability. I don't own OWC drives, but they're rated well, too. A one-TB drive will keep you going for a long time.
Process your movies as little as possible. Depending on he content, you can lose a little every time you transfer the data. Use a single format to manage your documents, since this will minimize conversion. Your process flow seems to rely on iMovie to manage movies. -
Where to download and manage video files at...
I take most my videos on my iPhone 4 now. I notice I can download them in iPhoto. They then show up in iMovie.
#1 - are they working off the same database/same files or is it copied over into iMovie?
I just purchased Aperture 3. It is supposed to work with video files.
I also do use a handheld HD video recorder on rare occasions, but haven't used it in a while to be honest.
I was pondering all this and am wondering the best way to manage my video. I use Final Cut Express for most of my video editing, although I do now use iMovie some since I purchased a macbook pro.
So I'm all over the place, I suppose. iPhoto to download, iMovie for some editing, FCE for editing, and now Aperture enters the picture.
I'm not sure if Aperture works off the iPhoto library or if I have to download it separately into Aperture.
Somewhere in this mixture, I guess I'm wondering the most simple direct way to manage my video files. What method should I import my video files: iPhoto? iMovie? Aperture? or does it matter? Do they all access the same basic structure of files or do they do their own thing and copy from one source to another?
And if I'm going to mix files from my iphone and hand held HD, I'm wondering the best way to basically download and manage video files.
Suggestions appreciated.Saving into iPhoto certainly works. If you save it there, iMovie can access it, but iMovie will not duplicate it.
You should have the option in Aperture to have Aperture be the default application and if so, your videos would be there. Once again, iMovie can see them and edit them without duplicating them.
However, to me, the most straightforward way would be to import the movies directly from your phone into iMovie. Then you can use all the library management features of the iMovie Events.
To do this, I would open the Image Capture Utility and plug in your iPhone. You should see the iPhone listed as a device in Image Capture. Right click on this device, and select iMovie as a default application. It has been a while since I did this, so that is approximate, but it should get you there.
