Re: Network Trash

2016-04-12 Thread Jim Luther
Apple doesn't support trash directories (or temporary item directories) on network volumes and hasn't for quite a while because there is no good mechanism to clean up trash on network volumes (i.e., if a user mounts a network volume, moves files to the trash, unmounts the network volume, and

Q_MOUNT kernel event and that's what causes the kNotifyVFSMount BSD notification to be sent. At that time, file systems must be ready to respond to requests correctly. If they don't, they have a bug. - Jim > On Sat, 1 Apr 2017, Jim Luther wrote: > >> Scott, if you walk through that code

As -[NSURL getResourceValue:forKey:error:] is documented, "If this method returns YES and the value is populated with nil, it means that the resource property is not available for the specified resource, and that no errors occurred when determining that the resource property was unavailable."

Re: searchfs support on APFS

2017-07-22 Thread Jim Luther
FSCatalogSearch is part of the deprecated Carbon File Manager API. The Carbon File Manager API exposes file IDs and directory IDs as 32-bit values and so FSCatalogSearch will never be supported on APFS (which use 64-bit file IDs and directory IDs). In 10.13: • PBCatSearch on APFS volumes will

As things work today... When a user drags a file system volume out the Devices sidebar list, the Visibility is set to NeverVisible for that device in the list (as you can see below). The Bookmark is a URL bookmark object (serialized) used to determine which file system volume should be hidden

Here's something that is kind of related that I ran into recently. If you have code that is checking the ownership and permissions of a file system object and attempting to correct the ownership and permissions if it is wrong, don't bother if the MNT_IGNORE_OWNERSHIP mount flag is set --

I don’t really have time to look at the current fts implementation, but… it has several options that effect performance (in particular, the FTS_NOCHDIR, FTS_NOSTAT, FTS_NOSTAT_TYPE, and FTS_XDEV options). If you are trying to compare fts to CFURLEnumerator (for example), use FTS_NOCHDIR and
