| Summary | 0000127: Always crashes while comparing system folders, in particular folder "JavaVM.framework" | ||||
| Description | VisualDiffer crashes systematically when comparing two System folders (I need to do this to figure out changes after some software installations). I found this by setting up VisualDiffer as follows: Left side: /Volumes/Boot1/System/Library/ Right side: /Volumes/Boot2/System/Library/ Upon analysis, I found that the crash still occurs when limiting the comparison to: Left side: /Volumes/Boot1/System/Library/Frameworks/JavaVM.framework Right side: /Volumes/Boot2/System/Library/Frameworks/JavaVM.framework Notes: 1- Neither Boot1 nor Boot2 is the current startup disk 2- This is regular system folder coming from a recent Mountain Lion installation (10.8) 3- The crash is near instantaneous after hitting "Show Diffs" The crash also occurs when working from the current startup disk, and setting both sides to the same folder: Left side: /System/Library/Frameworks/JavaVM.framework Right side: /System/Library/Frameworks/JavaVM.framework so it should be easy to reproduce the issue. I wanted to attach a copy of JavaVM.framework folder to this report, so I made several copies of it out of the System folder, but then I found that VisualDiffer does NOT crash when working on those out-of-context folders. I tried to add ".framework" to the default filter, but no effect It is worth noting that JavaVM.framework contains hard links, so maybe this issue is linked to issue # 122 that I previously reported | ||||
| Steps To Reproduce | To reproduce, that should do it: Left side: /System/Library/Frameworks/JavaVM.framework Right side: /System/Library/Frameworks/JavaVM.framework | ||||

I wish to know of any way-arounds, since I badly need VisualDiffer to compare system folders on my current project. How could I exclude such problem folders, or maybe just how to exclude aliases/symlinks /hardlinks since I suspect those are causing the issue??? Thanks! |
|
|
I'm investigating the crash that I've reproduced on my 10.8 machine It is not possible to exclude aliases/symlinks/hardlinks, this is a major bug that must be fixed. |
|
|
Ok found the problem, the *infinite* recursive calls end with app crash I've fixed simply stopping traversing symlinks, they appear as empty folders and the badge icon is shown to communicate to user it is a symlink. If you want I can send you the fixed version so you can test if it fits your needs. |
|
|
Yes please, I'd like to have the fixed version. Do you have access to my email as set in my account here? I will probably need to use it in a few day (I actually stopped using it because of that bug, it was in constant trouble). |
|
|
No need to know you email, I'll attach the file to this bug, |
|
|
Thanks, but sorry, I don't know where the file for the fixed version is. Or did you not post it yet? |
|
|
My internet connection is very slow, now you should see the file. PLEASE Note the copy doesn't is fully functional, this is an alpha. The symlinks folders are copied as empty folders |
|
|
Yes, I got it now. Thanks a lot. Will try later... Is it normal to bear the same version number as what I updated from the Mac App Store, i.e., 1.4.3? |
|
|
yes, it is normal and MAS version and this one can run side by side please remember copy doesn't work at all |
|
|
Copy doesn't work at all? or is it just that Symlinks not being followed? If the latter, then it would just be the perfect way I expect it to work (see my comment 166). I understand it is alpha, but I am surprised to see a symlink transformed into a folder (even if a symlink to a file?). Isn't a symlink just a simple file to start with? I have copied symlinks many times using Finder or Terminal, and they remain symlink files (although I know with Terminal, you can add parameters to follow links, one step or recursively) |
