Thanks for reporting this issue. I was able to reproduce your issue if I used a .icns file that was > 128K. I've just submitted a fix to the mainline codebase; it should be fixed in the next release of MacFUSE Core.
The problem was related to the getxattr "position" argument that is used on resource forks. When returning a synthesized resource fork to hold the custom icon, I was always returning the data for the entire resource fork rather than the subrange requested. This should only affect the case where your file system is using iconDataAtPath and the synthesized resource fork becomes larger than 128K. There isn't really a workaround for the 1.5 or previous MacFUSE releases. It should be possible on MacFUSE 1.7 to work around this by implementing: valueOfExtendedAttribute:ofItemAtPath:position:error: and returning the resource fork data yourself. You can use GMResourceFork to help you construct the resource fork data. This shouldn't be an issue on Tiger since it uses AppleDouble files (._foo) for resource fork data. Keep in mind that icon data with 512x512 representations can become quite large. In my experience I don't think using these in your file systems is worth the overhead. ted On Wed, Jul 9, 2008 at 6:40 PM, henrion <[EMAIL PROTECTED]> wrote: > > I've got a filesystem in Objective-C based off of the HelloFS sample > code.
