2019-10-07Remove unnecessary context parameter for new pipes.Kevin Krakauer
PiperOrigin-RevId: 273421634
2019-08-01tmpfs and ramfs Dirs should drop references on children in Release().Nicolas Lacasse
This is the source of many warnings like: AtomicRefCount 0x7f5ff84e3500 owned by "fs.Inode" garbage collected with ref count of 1 (want 0) PiperOrigin-RevId: 261197093
2019-06-13Plumb context through more layers of filesytem.Ian Gudger
All functions which allocate objects containing AtomicRefCounts will soon need a context. PiperOrigin-RevId: 253147709

2019-05-17Fix gofer rename ctime and cleanup stat_times testMichael Pratt
There is a lot of redundancy that we can simplify in the stat_times test. This will make it easier to add new tests. However, the simplification reveals that cached uattrs on goferfs don't properly update ctime on rename. PiperOrigin-RevId: 248773425 Change-Id: I52662728e1e9920981555881f9a85f9ce04041cf

2019-04-05Use string type for extended attribute values, instead of []byte.Nicolas Lacasse
Strings are a better fit for this usage because they are immutable in Go, and can contain arbitrary bytes. It also allows us to avoid casting bytes to string (and the associated allocation) in the hot path when checking for overlay whiteouts.

2019-03-18Remove references to replaced child in Rename in ramfs/agentfsMichael Pratt
In the case of a rename replacing an existing destination inode, ramfs Rename failed to first remove the replaced inode. This caused: 1. A leak of a reference to the inode (making it live indefinitely). 2. For directories, a leak of the replaced directory's .. link to the parent. This would cause the parent's link count to incorrectly increase. (2) is much simpler to test than (1), so that's what I've done. agentfs has a similar bug with link count only, so the Dirent layer informs the Inode if this is a replacing rename.

2019-01-14Remove fs.Handle, ramfs.Entry, and all the DeprecatedFileOperations.Nicolas Lacasse

2018-12-12Filesystems shouldn't be saving references to Platform.Rahat Mahmood
Platform objects are not savable, storing references to them in filesystem datastructures would cause save to fail if someone actually passed in a Platform. Current implementations work because everywhere a Platform is expected, we currently pass in a Kernel object which embeds Platform and thus satisfies the interface. Eliminate this indirection and save pointers to Kernel directly. PiperOrigin-RevId: 225288336 Change-Id: Ica399ff43f425e15bc150a0d7102196c3d54a2ab
