Soft links and endpoints

Hello,
I would be grateful if someone would confirm to me the following:
A soft link always relates to an external endpoint.
Is the above statement true?
Julien.

Soft, hard, and standard links always apply to internal endpoints (external and internal endpoints are defined by the spec in section 5.1.7). They are used to govern connections made by the NMR between service consumers and providers.
External endpoints are used only for endpoint reference (EPR) generation. (External service providers are considered internal endpoints, since they are proxied by the binding components.)

Soft links and inodes

It's my understanding that a unix file consists of three components: a filename, an inode, and the data. So if you create a text file called "original", you get something like this:
original -------> inode ------> data
Then if you create a soft link to the original file, the soft link has its own filename, inode, and data--where the data is the filename of the original file. So for instance, if you use the command:
$ cat soft_link
it traverses the chain:
softlink-->softlink's inode-->data-->original-->original's inode-->original's data
On the other hand, if you create a hard link to the original file, the hard link does not get its own inode; its filename points to the original file's inode. So for instance, if you use the command:
$cat hard_link
it traverses the chain:
hard_link ---> original's inode ---> original's data
and then the original's data is displayed.
However, on mac os x when I do an ls -i on the soft link to display its inode, it displays the same inode number as the original file. Furthermore, if I rm(remove) the original file and recreate it using touch original, the new original gets a new inode number, and the soft_link's inode changes to the new inode. I don't understand that. I expected that the soft_link initially would have a different inode number than the original, and that the soft link's inode would not change when the original was recreated.

You may want to read this page: http://linuxgazette.net/105/pitcher.html
It contains a pretty good explanation of the difference between a soft link and a hard link but it doesn't directly answer your question about the inodes. However, it appears that there's a subtle difference in the way "ls" acts depending on whether you give it a filename or not and depending on whether you use the "-l" option in conjunction with "-i".
Here, with filenames and without "-l" it appears that basic.file and softlink.file have the same inodes:
<pre>
iMacHerman:~/Desktop/temptest steve$ ls -i basic.file
3723769 basic.file
iMacHerman:~/Desktop/temptest steve$ ls -i softlink.file
3723769 softlink.file
</pre>
Yet here, without filenames and using the "-l" option you can see that the softlink.file's inode is different (while hardlink.file is the same):
<pre>
iMacHerman:~/Desktop/temptest steve$ ls -li
total 24
3723769 -rw-r--r-- 2 steve steve 27 Feb 24 08:01 basic.file
3723769 -rw-r--r-- 2 steve steve 27 Feb 24 08:01 hardlink.file
3723768 lrwxr-xr-x 1 steve steve 10 Feb 24 07:59 softlink.file -> basic.file
</pre>
Here using both a filename and "-l" you again get softlink.file's actual inode:
<pre>
iMacHerman:~/Desktop/temptest steve$ ls -li softlink.file
3723768 lrwxr-xr-x 1 steve steve 10 Feb 24 07:59 softlink.file -> basic.file
</pre>
And here leaving off filename gives you softlink's actual inode even though the "-l" option was not used:
<pre>
iMacHerman:~/Desktop/temptest steve$ ls -i
3723769 basic.file 3723769 hardlink.file 3723768 softlink.file
</pre>
So it appears that if you do not use the "-l" option and you give "ls" a filename that it follows the softlink and reports the inode of the original file. Other variations (using "-l" or leaving off the soft link's filename list the soft link's actual inode. This seems a little confusing to me and possibly a bug in "ls"... but maybe there's a reason for it working this way???
Steve
PS - and if you do what you described, delete and then recreate the original "basic.file" it will get a new inode. And if you use the first variation of "ls" (without "-l" but with softlink's filename) then it will indeed appear that softlink's inode changed to match the new basic.file
<pre>
iMacHerman:~/Desktop/temptest steve$ rm basic.file
iMacHerman:~/Desktop/temptest steve$ touch basic.file
iMacHerman:~/Desktop/temptest steve$ ls -i basic.file
3723912 basic.file
iMacHerman:~/Desktop/temptest steve$ ls -i softlink.file
3723912 softlink.file
</pre>
But using one of the other options shows that softlink's actual inode did not change:
<pre>
iMacHerman:~/Desktop/temptest steve$ ls -li
total 16
3723912 -rw-r--r-- 1 steve steve 0 Feb 24 08:29 basic.file
3723769 -rw-r--r-- 1 steve steve 27 Feb 24 08:01 hardlink.file
3723768 lrwxr-xr-x 1 steve steve 10 Feb 24 07:59 softlink.file -> basic.file
</pre>

Soft links and xcode projects

In other unix environments using soft links ("ln -s") is a handy way of "abstracting away" at the file system level what a file or directory actually contains, so that its contents can be easily changed without having to modify the original file or directory. In other words, if I have eg. three versions of the same file, and several projects share the usage of one of those files, I can easily change which version of the file those projects will use by simply making a softlink that points to the file I want, and make those projects depend on that softlink (they see it as a regular file). If I later want to change the file in question, I only need to change the softlink to point to another version of the file.
This is especially useful when dealing with a third-party library that gets regular updates. I can install the third-party library somewhere, with the version number of the library in the directory name, and have a more generic directory name as a softlink (as a concrete example, I could have a softlink named "cocos2d" pointing to a directory named "cocos2d-iphone-0.99.5"). If I update the library, I can install it in a new directory (eg. "cocos2d-iphone-1.0.1") and simply change the softlink to point to the new directory, and then recompile the projects that depend on it.
The problem is that Xcode doesn't like softlinks. I don't know if this is a feature of MacOS X in general, or a quirk in Xcode in particular. The problem is that Xcode doesn't want any softlinks in any of its paths, and instead always resolves where the softlink is really pointing to. Thus if I add, for example, the file "libraries/cocos2d/cocos2d-ios.xcodeproj" to the project, what ends up in the project is actually a reference to "libraries/cocos2d-iphone-0.99.5/cocos2d-ios.xcodeproj". Thus the whole softlink is circumvented, making it useless. If I update the library in question, I have to go through all the projects that use it and change the references to point to the new directory. This causes only needless extra work.
This resolving of softlinks only happens when adding a new file to the xcode project. Xcode doesn't seem to change them afterwards, if they already exist in the project. In the past I could get around this problem by editing the project file directly with a text editor and forcing the path to refer to the softlink. However, all the paths in xcode 4 projects seem to be obfuscated, making this impossible. Another possibility is to rename the directory in question with the name of the softlink, then add it to the project, then restore its original name and then add the soft link.
Is there any better way of doing this?

Hello I have probably exact same problem with source files whereas a constant location (my softlink) points to different version of the sources in a repository. For example:
../MyProject/DependantProjetXyz could point to
../Repository/DependantProjectXyz/V1.0
../Repository/DependantProjectXyz/V1.1
My xcode project is setup with ../MyProject/DependantProjetXyz which is pretty useful as I don't need to update all the include and lib path everytime I update the dependancies.
The main problem I am facing is that if I have a compilation error in the dependancies, xcode isn't able to automatically bring me to the error. It simply open the file and position at the very first line in the file. No highlight.
I am forced to use contextual menu on the error then reveal in the log to find the line number and manually navigate to that line. In other words, I am almost back to good old command line compilation with separate text editor...
BTW, this was all working fine before upgrade to xcode 4.
Was a bug filed on this issue?

Sharing album artwork with fast user switching and soft links

We have 4 users, 4 iPods, 4 sets of playlists. Each has their own account. All the music lives on an external drive and each iTunes is set to store its music in the same shared folder. That all works fine.
Now we're getting into album artwork, and I want to share that too. I found a posting somewhere that suggested a soft link from /Users/Me/Music/iTunes/Album Artwork -> /Volumes/BigDrive/iTunes Artwork. I did that with one user and it worked fine - copied Album Artwork folder and set soft link and voila, all the art. I also set all permissions to allow r/w from everyone.
But when I set the soft link from 2nd user, iTunes shows no art. I can browse all the art files fine from that users Finder.
Thanks for any help!
mac mini Mac OS X (10.4.9) iTunes 7.1.1

And just like that I may have found the solution! IT suddenly occured to me that one of the settings that got changed when we imported my wife's profile was a change to the sleep settings. Previously, I had had my iMac set to never go to sleep, since it shares our media with the rest of the house and runs eyeTV to record TV shows and such. For a little while after my wife's account was imported the settings to changes so that the computer would go to sleep after 15 minutes. I'm not totally sure why, but I think having that set up somehow meant that when we switched accounts my other account just "went to sleep" and therefore stopped sharing the iTunes library. After I noticed the change and switched the computer back to "never" for sleep the problem seems to have stopped.
So perhaps check your sleep settings? That seems to be the only change I can think of that got things working correclty for me. I'll keep digging though and see if I can find any more helpful info. Good luck!

JDK 1.3 Soft Links in CLASSPATH

Hi,
I found that the JDK1.3 javac compiler doesn't
follow soft-links in unix filesystem. Whereas in
JDK1.1.6 I was able to specify classpath through
soft links also.
Can anyone give more insight into this? Can this
behavior be tailored - either via JDK or UNIX?
Thanks,
Hari

This looks like Bug 4266026 in the Bug Database. It's fixed in JDK 1.4 and maybe 1.3.1.

Classloader & soft links & stat calls

Solaris 7 - WLAS 4.5.1
Our servlet class loader is loading classes that it resolves thru a soft

satisfactory level, does anyone have any idea about performance with respect
to loading classes and the soft linked directory structure?
Thanks,

We have a stable 4.5.1 that we are migrating to another server, given that
we have a stable system we want to migrate as-is to the new server, then
migrate from 4.5.1 to 5.1 ... then to 6.x. I cannot convince the client to
go to a new server with a new application server all in one step.

Same answer as to your other question. WLS 5.1.
You can spend weeks or months trying to figure this out or got to 5.1 andget
it over with.
What's the point in solving the problem for 4.5.1 if
1) going to 5.1 is painless
2) you're going to go to 5.1 anyway

IPhoto 9.1.1 ('11) messed up soft links

I recently noticed that iPhoto is not following all of my aliases to find the original photos. I do not copy my photos to iPhoto, so when I import them, iPhoto creates an alias to the original file (which is on the same volume).
It turns out that iPhoto has a problem with a whole bunch of Unix style soft links that I created within the iPhoto directory structure when I moved my photos from an external drive to my boot volume. When I did this, I had written a shell script to search for the original on its new location and replace the stale OS X Alias (which pointed to the old volume) with a soft link to the new file. It seemed to work fine way back then (1/31/08).
At first, I thought that iPhoto was not following the soft links. However, when I examine the original files to which the soft links pointed, they have all been changed to Aliases!!!! It appears that the original photo data is still intact in each of the files, yet if you do a Get Info, it is an alias.
I've tested a couple of ideas on solutions:
a) cp -X of the original file to get rid of the extended attribute info. Still doesn't work. However, the new file (without the extended attributes) does open in Preview so that I can see the original jpg.
b) replacing a soft link with a Finder Alias to the 'cp -X' file. Still doesn't work.
What should I do now?
Thanks!
Henry Flurry

Hmm ... that doesn't ring true. iPhoto only has problems with the photos that were soft links. Here's what I imagine happened:
1) iPhoto recognizes that the original photo is a link
2) It then decides to update the extended attributes and, assuming that the file is an Alias instead of a Unix Soft Link, opens the file directly to update the extended attributes
3) Because the file is a soft link, the fopen (or whatever it uses) opens up the original file directly, and not the link
4) When the extended attributes are updated, they end up getting added to the original data file.
I'll admit that this is conjecture and I don't know why iPhoto would be updating the extended attributes. Does iPhoto store any data in this? Could this be something further I need to update?
I'd like to poke around a bit more. For iPhoto 11, what is the directory structure of the iPhoto library? Perhaps I'm making wrong assumptions on which files to change.
Thanks!

Use a soft link to move /Users to another volume

I'd like to move /Users to another volume, so that I can have the OS and applications on an SSD, without having to get an SSD of several terabytes.
Users log in to a Mac Pro using Active Directory accounts. Consequently, they do not have accounts on the Mac, and I cannot use Mac user properties to move their home directories. Also, the set of users who can log in is limited only by the AD user base, which has tens of thousands of entries. Of course, I cannot change the AD schema. So it has to be a solution that happens automatically. If a new user logs, her home directory must be automatically created on a volume which is not the startup.
I made a soft link from the startup volume to the new volume where I want the homes to go. This seems to work. After a restart, all the applications I tried had no problem following the soft link.
Is there any danger here? Or is there some better solution? I tried, following a suggestion which apparently worked in older versions of the OS, to make an entry in /etc/fstab to mount the new disk as /Users. This did not work in Mavericks (my test machine). The new disk appeared in Disk Utility, but could not be mounted. Perhaps it would work on Mountain Lion, which is the machine where this change ultimately needs to be implemented.
I will be obliged for any suggestions or warnings.

Reading through the article you referenced, I noticed they talked about downsides to moving home directory.
The issue about non-boot drives not being as protected as the boot drive.
Specifically related to permissions. I'm not exactly sure what they mean. If you ignore permissions on the non-boot drive that means that others can browse any of those files?
I'm assuming they mean you would have to change the permissions on the non-boot drive? But does that mean that only the original owner can change those permissions? Or can any user change permissions on a non-boot drive?
How is this different from user files on the boot drive? Can't you change permissions on your home directory?
I'm interested in moving my directory to the non-boot drive, so I'd like to understand the downsides. Especially anything related to user security.
Thanks.

How to update link and import data of relocated incx file into inca file?

Subject : how to update link and import data of relocated incx file into inca file.? The incx file was originally part of the inca file and it has been relocated. ------------------- Hello All, I am working on InDesignCS2 and InCopyCS2.

Getting links and its names from a html file

Hi everyone
My problem about the a getting links with name from a html file. For example
İn a web page in this site ?SUN? when use click SUN the browser open http://java.sun.com
İ want both of them, so the links and name. I can succeeded the get link but i don t know how to get the link name.
For example :
setRightComponent(Component)
İn this code segment i want to get B tag. But how i don t know. To get A tag i used this code
List result = new ArrayList();
try {
// Create a reader on the HTML content
URL url = new URI(uriStr).toURL();
URLConnection conn = url.openConnection();
Reader rd = new InputStreamReader(conn.getInputStream());
// Parse the HTML
EditorKit kit = new HTMLEditorKit();
HTMLDocument doc = (HTMLDocument)kit.createDefaultDocument();
kit.read(rd, doc, 0);
// Find all the A elements in the HTML document
HTMLDocument.Iterator it = doc.getIterator(HTML.Tag.A);
while (it.isValid()) {
SimpleAttributeSet s = (SimpleAttributeSet)it.getAttributes();
String link = (String)s.getAttribute(HTML.Attribute.HREF);
if (link != null) {
result.add(link);
it.next();
İ can use B tag but i don t know hot to get its value because it has no prefix such as HREF....
i am sorry if i use a bad explanation style or incorrect word.

Hi Jeff I have uninstalled Muse from my applications and have tried to download the new version but it displays a message 'file not found'. I have included a screenshot.

On YouTube, I can't play playlists there. It says I need to update my Java and it is updated already. When I go to different sites like Yahoo! the links and images are all distorted. This is the second time this has happened to me now

Hello Firefox,
I am having problems with my Firefox's image processor I believe. My web browser is fine but then a few minutes later I get some weird look on my page. It then just stays here and I can't fix it. When I go to Yahoo all the links and images do not look normal. I really cannot explain this and wish I could send a picture instead. When I go to the Log in page for Facebook I do not see the image of the small faces networking around the world. It's blank and the links are widely spread apart. With YouTube the page is also distorted. Nothing is arranged properly. I can watch videos. However when I go to someone's profile or a playlist videos cannot play or show up. It says I need to update my Java player and it is already updated. It still happens when I uninstall and re install back. I was only able to fix this problem by uninstalling everything related to Firefox. I do not know how to solve this any other way. I don't like it when all my information is lost such as saved passwords and bookmarks. If there is any way to solve this thanks. I don't want to uninstall this again.

My iMessage says it needs to be activated but i clicked the link and it already says its been activated...how do i get my imessage to turn on?

I just updated my 3GS to the 6 and everything has turned out well, but when i started signing up for the imessage i ran into some problems. I went through each step as it asked and then it sent a verification link to my email and thats where im lost at. I went to my email and clicked on the link and it says my account has already been verified. When i go back to settings and down to messages where you turn on imessage it says "waiting for activation. What is going on? thanks in advance

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

Safari 6.0 crash when right clicking a link and choosing open in new tab

Hi all, just a general question. I admit i did not search the forums yet. Hopefully this little annoyance can be resolved.
When using safari on say CNN.COM i'll right click on a link and choose Open in new tab. safari randomly disappears. no crash warnings, just gone. I can open it right up and be fine sometimes all day. This has happened to me about 5x since ML was released (i wiped my laptop the day it came out)
This has happened on a couple of different website at different times of the day. only safari was running. No other apple apps have this issue.
I have a MacBook Pro from earily '08 type 4,1
i have only apple software on this machine
i do have adobe flash installed v11.3 updated today.
i do have lastpass enabled
i do have ad-block disabled
While i'm waiting for help from you guys i'll disable all addon's and try to remove adobe to see if that is the issue. Is there any other steps i can try like delete .plist file or maybe even trying a new user profile. I am a IT professional and am not afraid to get my hands dirty trying to get this resovlved.
Thanks in advance.
P.S. i'll search the forums too and if i see a similar post i'll remove this one.
Bill Siegfried.

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the page that opens.
Step 1
Enter the name of the crashed application or process in the Filter text field. Post the messages from the time of the last crash, if any — the text, please, not a screenshot.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in the Console window, look under User Diagnostic Reports for crash reports related to the process. The report name starts with the name of the crashed process, and ends with ".crash". Select the most recent report and post the contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

How can I stop from getting the "Firefox is already running" error message when trying to open links and FF has already been opened through a symbolic link?

I use symbolic links and program shortcuts as a way to easily open different Firefox profiles ie. one for casual/personal use and another for work. This works well, but I get the "Firefox is already running, but is not responding" error message if I try to open external links with FF as my default browser. FF is actually open and running fine, but I guess it doesn't acknowledge this fact because of how I'm originally starting the process.
I wasn't able to add the symbolically linked executables to the default program pane. Is there a way to bypass this error or other way to fix this?
The solution to the question linked below is what I'm using to open the different FF profiles.
http://superuser.com/questions/255312/pin-same-app-multiple-times-in-windows-7

hello, this is probably happening when you run the default profile with the -no-remote switch.
