2022-05-05ripple/fossil/mount: document how . and .. workedef
Change-Id: I6c4d471b2840613d30ee95efe14547f2f9c0db6b
2022-05-05ripple/fossil/mount: terminate out-of-bounds Node::find earlyedef
Node::find would walk the tree all the way down and to the right if given an out of bounds index. This doesn't affect the return value (None), but it does waste some cycles walking down all the way to the deepest rightmost leaf. Change-Id: Ic2f72aa96291a25819fc6c3c2f060fe0182a7663
2022-05-04ripple/fossil/mount: don't allocate on readdiredef
Change-Id: I319a2de0da0ff71f0f337e5a17ef199f23254b11
2022-05-04ripple/fossil/mount: back memtree with a single Vecedef
A single linear array does everything we need here, since we don't actually use the cheap writes the BTreeMaps would permit us, and we save ourselves the hassle of maintaining two parallel lookup structures. Change-Id: I418b0aaa7a3191fab3195f36f2c68ac0f5f0382b
2022-05-03ripple/fossil: handle missing blobs more gracefullyedef
Change-Id: I8a928b57ecc81bea31d757e73b9ece9474628db4
2022-05-03ripple/fossil/mount: expose arbitrary directories by digestedef
This makes the filesystem more like eg /nix/store. ~/src/ripple> ./target/release/add fossil puma5z7rnb4tmnqk8ixgryobay9ifg8txh69635snkgx8dis6quo ~/src/ripple> ./target/release/mount & ~/src/ripple> ls mnt/puma5z7rnb4tmnqk8ixgryobay9ifg8txh69635snkgx8dis6quo benches build.rs Cargo.toml src Change-Id: Ic35f81ffec521f49ce2e4a414919e1ff717d7041
2022-05-03ripple/fossil/mount: make node references more flexibleedef
Essentially, memtree::Node becomes more of a NodeRef, and Node gets renamed to NodeBuf. This permits calling Node::find with an arbitrary owned Directory, without having to move it into the enum. Change-Id: I93838932a00f2e2073e3c7ddf7ce8d302ed4ed59
2022-05-03ripple/fossil/mount: memtree API cleanupedef
This replaces the tuples with a DirectoryEntry struct. Change-Id: I42a49fee03f7abfac9143c48106ebeb964814ca9
2022-05-03ripple/fossil: don't expose protobufs in the frontendedef
Previously, the CLI took Directory protobufs as input or wrote them as output. Now we just deal in store hashes. Change-Id: I5e0f0f33929ede43d971080c33bdb865f1832b2e
2022-05-03ripple/fossil/add: only accept a single directory argedef
This changes it from building an implicit top-level directory containing all its args, to simply accepting a directory. Change-Id: Iaf00e07d8568367b9eb27f365e8a2eaac3576974
2022-05-03ripple/fossil: make store path configurableedef
Change-Id: Ic410619a6115a7059b79593c6fade38236d4e8c1
2022-05-03ripple/fossil: use clapedef
This adds clap to all our binaries. Only add currently takes any args, but previously, the others did not reject args as they should. Change-Id: I6257fb3b218c624ee0124f6ed7313a579db88c4c
2022-04-28ripple/fossil/mount: don't serve short readsedef
FUSE doesn't actually respect the usual read() contract, so this resulted in us serving truncated files. Change-Id: I8bdb0bd7f03162fb78774f3f84daeefc5ba5e3b1
2022-04-25ripple/fossil/mount: implement incremental file readsedef
Change-Id: Iae189c3107a6841bcbdd75bb57dde785f9548130
2022-04-24ripple/fossil/mount: implement stateful file handlesedef
This will primarily allow us to amortise metadata lookups. Change-Id: Ic92781bf1ded5af62f6e955322bb89623afb2061
2022-04-15ripple/fossil/mount: drop bmapedef
We'll never write a direct block-mapped filesystem, so this won't become relevant. Change-Id: I512ac44fc40f3969c2d54b93a1e2725628f46ed4
2022-04-15ripple/fossil/mount: move writing methods into their own sectionedef
Change-Id: Ia5b63f3be625c738c58a915bc46114cac7acc0a5
2022-04-15ripple/fossil/mount: correctly serve executable filesedef
Change-Id: I1bc7c0db7a0feeb5cb809e9382bf51816ec082c1
2022-04-15ripple/fossil/mount: rm rmdir stubedef
rmdir should be rejected with EROFS. For some reason, the initial EROFS pass missed this. Change-Id: Ib8d7b21b42fcf52e696041aa0ba41be5ab20d326
2022-04-15ripple/fossil/mount: unbreak rustfmtedef
Apparently, rustfmt bugs out if you mix triple-slash and double-slash comments on a struct literal. Change-Id: I609ac42f86875b48947766fa9d67af7ef8997b9b
2022-04-12ripple/fossil/mount: outline node handling logic from file_attr callersedef

2022-04-12ripple/fossil/mount: serve an in-memory filesystem treeedef
Change-Id: I92073aae32bcf603799b83717635a13edbbef190
2022-04-11ripple/fossil/mount: serve a small, static filesystemedef
Serve up an entirely hardcoded minimal filesystem tree, so we can see most of the FUSE plumbing working already. Change-Id: I13c4b534c8dd159d2d2e177497b33f1bec3849ad
2022-04-11ripple/fossil/mount: stub out anything we don't want to implementedef

2021-08-14ripple/fossil: a basic content-addressable storeedef
Fossil stores content-addressed blobs of file contents and Protobuf-encoded directory listings, backed by Sled. Change-Id: I8b49de6342218ca00755cec980b1d0cfb18878a7
