2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289

2019-04-30Implement async MemoryFile eviction, and use it in CachingInodeOperations.Jamie Liu
This feature allows MemoryFile to delay eviction of "optional" allocations, such as unused cached file pages. Note that this incidentally makes CachingInodeOperations writeback asynchronous, in the sense that it doesn't occur until eviction; this is necessary because between when a cached page becomes evictable and when it's evicted, file writes (via CachingInodeOperations.Write) may dirty the page. As currently implemented, this feature won't meaningfully impact steady-state memory usage or caching; the reclaimer goroutine will schedule eviction as soon as it runs out of other work to do. Future CLs increase caching by adding constraints on when eviction is scheduled. PiperOrigin-RevId: 246014822 Change-Id: Ia85feb25a2de92a48359eb84434b6ec6f9bea2cb

2019-03-14Decouple filemem from platform and move it to pgalloc.MemoryFile.Jamie Liu
This is in preparation for improved page cache reclaim, which requires greater integration between the page cache and page allocator. PiperOrigin-RevId: 238444706 Change-Id: Id24141b3678d96c7d7dc24baddd9be555bffafe4
2019-02-07Make context.Background return a global background context.Nicolas Lacasse
It currently allocates a new context on the heap each time it is called. Some of these are in relatively hot paths like signal delivery and releasing gofer inodes. It is also called very commonly in afterLoad. All of these should benefit from fewer heap allocations. PiperOrigin-RevId: 232938873 Change-Id: I53cec0ca299f56dcd4866b0b4fd2ec4938526849

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
2018-10-23Track paths and provide a rename hook.Adin Scannell
This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55
