2022-05-01ripple/fossil: benchmark Chunker using Criterionedef
Performance hovers around 300MiB/s on my machine. Change-Id: I387ccbf065c0b667824ede0675e6a295722f6d4b

2022-05-01ripple/fossil/chunker: simplify and test Chunker::size_hintedef
Full test coverage for fossil/chunker! :) Change-Id: I0436a266220bbed6d85c291dcca827d1770294dd
2022-05-01ripple/fossil/chunker: remove Rolling::try_from_sliceedef
We never actually use this directly, and the resulting branch is test coverage noise. Change-Id: Id32b056ca0cd57965d829085d768012e5a9e05ce
2022-05-01ripple/fossil/chunker: test early cutoff for <= MIN_CHUNK_SIZEedef

Free test coverage win! :) Change-Id: I9bab30e0f0da2810c770cbd8ba5603f0eb2b28e7
2022-05-01ripple/fossil/chunker: clarify MAX_CHUNK_SIZE testedef
Change-Id: Ia5adb5a9056fd0e9ddcd8667c56129219b9d6f52
2022-05-01ripple/fossil/chunker: handle and test boundary condition correctnessedef
This ensures that MIN_CHUNK_SIZE-sized chunks can actually be emitted, and adds tests for both MIN_CHUNK_SIZE and MAX_CHUNK_SIZE chunks. The behaviour for all cases now verifiably matches casync. Change-Id: Ie0bfaf50ec02658069da83ebb30210e6e1963de6
2022-05-01ripple/fossil/chunker: use b-strings for test dataedef
This takes up 80% less vertical space for something that isn't readable to humans to begin with. Change-Id: I04aa27755f0b8d6cdaa83d766f8bf0ecbe3b7a46
2022-04-28ripple/fossil: use to_be_bytes rather than write_u64edef
Change-Id: I7eb02482772f48ca9f486f514b89652a9c5730cd
2022-04-28ripple/fossil: ensure durability of add_pathedef
sled doesn't actually promise not to eat your data until you invoke flush. This is observable under normal circumstances as add_path occasionally just not committing anything to the store. While we're at it, ensure we're syncing the chunks file data to disk, so the database *might* actually be consistent. We're not going for full crash-correctness yet, mostly for performance and complexity reasons. Change-Id: I6cc69a013dc18cd50df26e73801b185de596565c
2022-04-28ripple/fossil: deduplicate using content-defined chunkingedef
This implements casync-style content-defined chunking and deduplication. Change-Id: I42a9b98e1140bed462a5ae1e0aba508bebc9fa0e
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
2022-04-28ripple/fossil: outline write_blob_inneredef

2022-04-26ripple/fossil: use the default sled tree for global metadata, not blobsedef

2022-04-25ripple/fossil: store bao outboard tree in the blob metadataedef
One step closer to genuine incremental blob reads. Change-Id: I796710820c1b69baad91a6dc65f9d7f0dee311d3
2022-04-25ripple/fossil: store blob metadata as protobufedef

2022-04-24ripple/fossil/mount: implement stateful file handlesedef
This will primarily allow us to amortise metadata lookups. Change-Id: Ic92781bf1ded5af62f6e955322bb89623afb2061
2022-04-24ripple/fossil: implement io::Seek for RawBlobedef
Change-Id: I625530fe2f4db89be5889e46f0a5ed50727c8cd1
2022-04-23ripple/fossil: implement a more lightweight blob store backendedef
The sled chunk store works fine, but has pretty awful performance, since sled just doesn't make a particularly good large blob store. This change replaces it with a file-based store using sled purely as a metadata store. Adding LLVM's source tree takes about 120s before, and about 15s after. Change-Id: I5fb22ea79a006fa6bcf5351921038f57f2484112
2022-04-20ripple/fossil: prefer anyhow::Result over io::Resultedef

2022-04-19ripple/fossil: prepare for seekable, streaming blob readingedef
This implements blob reading in terms of RawBlob, a fairly naive streaming blob reader. For now, we still only use it for simple one-shot reads. Change-Id: Iecd4f926412b474ca6f3dde8c6055c0c3781301f
2022-04-19ripple/fossil: add read_write testedef

2022-04-18ripple/fossil: use blake3::CHUNK_LEN as chunk sizeV
This will pave the way for BLAKE3 verified streaming, so we won't have to read objects into memory in their entirety. Change-Id: Ic68dee2ad81448db4969b8c423f0876f0e0272e0
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: 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

2022-04-11ripple/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
