Eject oddity

site_archiver(a)lists.apple.com Delivered-To: darwin-kernel(a)lists.apple.com Thread-index: Acghj0Tlg0VUpI2CEdyRLgAX8si2KA== Thread-topic: Eject oddity User-agent: Microsoft-Entourage/11.3.6.070618 Hi, I have an odd issue with a storage driver for removable media. If you select the media and unmount it by dragging it to the trash, or by selecting Eject from the Finder's File menu, the media unmounts without a problem. But, if you press the Eject button on the keyboard, it doesn't unmount. The Finder still displays that eject graphic, indicating it processed the key press. The media does unmount via the Eject button if the generic IODVDStorageDriver is used instead of my subclass. I don't see any obvious reason why. Anyone with a thought about this? Thanks in advance, Eric _______________________________________________ Do not post admin requests to the list. They will be ignored.

The steps to reproduce are the following: - format volume - mount volume - open volume in the Finder - create a new folder in the Finder (it will be called "untitled folder") - rename it. For example to "FirstFolder" - create another folder (it will be called "untitled folder") - now, when clicking on the first folder ("FirstFolder"), it's name and contents will change to those of "untitled folder". When double clicking on it the contents of the second folder will be shown. Everything is ok with the on-disk structures of the volume. It seems the bug is related to Finder and its interaction with filesystem plug-in. Carbon maintains a { volume id, file id } tuple for identifying files, and treats naming information as a user thing. So when it goes to display a name, it does so by looking up the name from the tuple. If you do not properly maintain separate, unique identifiers for different files in your on disk format, then you will see the behaviour you are seeing (generally, these correspond loosely to having different inode numbers coming back from stat/getattrlist).

Binary driver licensing

site_archiver(a)lists.apple.com Delivered-To: darwin-kernel(a)lists.apple.com Hi, -Dave _______________________________________________ Do not post admin requests to the list. They will be ignored. Darwin-kernel mailing list (Darwin-kernel(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-kernel/site_archiver%40lists.… With the release of Darwin 9 and the Darwin 9 source packages I am wondering if there is any plan to release some of the binary driver kernel extensions as prior Darwin releases have contained. Right now, one must apparently purchase a copy of OS X to be able to run Darwin since several pretty key kernel extensions (e.g. the ACPI platform expert) are not part of the Darwin release. Prior Darwin releases included the binaries with a license to use them and redistribute them in the APPLE_DRIVER_LICENSE.txt file. Is there any chance that these binaries will again be licensed for free use or is AppleI386GenericPlatform the only option now? This email sent to site_archiver(a)lists.apple.com
