Announcing FUSE for macOS 3.4.1 Posted on 24 Jul 2016
Release Notes
-
Remove obsolete task working set cache handling
When mounting a volume with the
noubcoption the kernel extension used to set thenoexecflag for the mount in order to also disable the task working set page cache on disk. However, since the task working set mechanism has been removed in Mac OS X 10.5 thenoexecflag is no longer needed. -
Ignore vnode name cache hits when creating a file
See osxfuse/kext#4 for details.
-
Always set
O_EXCLforFUSE_CREATErequestsThe macOS kernel expects all create calls to return
EEXISTin case the file already exists, regardless of whetherO_EXCLwas specified or not.Resolves osxfuse/osxfuse#209
-
Add mount-time option
excl_createIf the mount-time option
excl_createis specified, theO_EXCLflag will only be set for “truly” exclusive creates, i.e. create calls for which the initiator explicitly set theO_EXCLflag. This allows distributed file systems to determine whether or not to acquire a potentially costly lock to prevent remote create races. Nonetheless, the file system still needs to make sure that there are no local create races. -
Fix mount-time option parsing
Fixes the following error when using the
daemon_timeoutmount-time option in combination with a volume name containing the word “union”.mount_osxfuse: invalid value for argument daemon_timeout -
Don’t kill the file system on short reads
A FUSE user space server receives file system requests from the FUSE device by allocating some memory and calling
read(2). Obviously, the request must fit into that buffer. If it doesn’t, we used to kill the file system.Linux FUSE handles short reads differently. Instead of killing the file system it returns
EIOorE2BIG(in case ofFUSE_SETXATTRrequests). This change aims to replicate the Linux behavior on macOS.Addresses osxfuse/osxfuse#293
-
Remove callbacks for interrupted tickets
Make sure to remove a ticket’s callback when marking it as answered. Otherwise the ticket will be retained by the callback queue until the volume is unmounted.
- Minor optimizations and code cleanup
- Switch to secure website URL
