2022-07-29ripple/minitrace: match identifier style in macrosedef
Having macro identifiers match the "real" identifier style makes macro code markedly more readable. Change-Id: Ib675390cc04941ce782c75b2ee686709441081fc
2022-07-29ripple/minitrace: pluralise newfstatat flags parameteredef
Change-Id: I025b5f707b15933c4dccdf36ce9e2c8d8673fe74
2022-07-28ripple/minitrace: bitflags-ify mmap/mprotect protection flagsedef
Change-Id: Iaf6d5717e2d83a6f81fda34da086311d21f345c2
2022-07-28ripple/minitrace: mark file descriptor parametersedef
This doesn't specifically handle * the distinction between borrowed/owned file descriptors (in non-return positions, that only applies to `close`) * "nullable" fd parameters (-1 for not-present) * other sentinel fds, like AT_FDCWD * fd validity in general Change-Id: I00fa68ec94b8f24e28c661d0c007becb37c0a5f3
2022-07-27ripple/minitrace: remove GRND_ prefix from GrndFlagsedef
Change-Id: Icfcab2fccc1c152a694dfba3ba1e272cdacdbfab
2022-07-27ripple/minitrace: parse mmap flags strictlyedef
Change-Id: I56731f205e065bf501fd31a69c71c10aa7a2f720
2022-07-27ripple/minitrace: mmap fd is an i32, not u64edef
Change-Id: I092d4f47231d560a0c4ac023e63051def34c2c92
2022-07-27ripple/minitrace: better errors for invalid syscall argsedef
Change-Id: I26356c9b88c838e3c87e4083ac17f958c7c57bb7
2022-07-27ripple/minitrace: introduce syscall_bitflags!edef
Squeeze the bitflags / SyscallArg impl boilerplate into one macro. Change-Id: I5b5213b6f3ee11bc61b6f8439ceb2510ef6dffec
2022-07-27ripple/minitrace: implement SyscallArg for bitflagsedef
Change-Id: I1b4e7e01b5d5c840ac2e94f9637552f71e61ed04
2022-07-27ripple/minitrace: disable dead_code lint on SyscallArgsedef
Every single syscall arg producing a warning is just noisy. Change-Id: I339260886110e2982217ebbf9d29cb1cf91c747c
2022-07-27ripple/minitrace: refactor syscall interpretationV
We separate type-based parsing of syscall arguments from more detailed validation based on multiple parameters or on specific values. The former is implemented with a macro that takes syscall signatures and generates the relevant enum variant and parsing code. Co-authored-by: edef <edef@unfathomable.blue> Change-Id: I7e334d3e128e7b1461bfd6fae7c8ec5dd6ada0a8
2022-07-27ripple/minitrace: fix newfstatat dirfd handlingedef
Same bug as Ied63822001c8700fc71c89ec16d18036fbc33972, hiding missing behaviour around dirfd. newfstatat(AT_FDCWD, path, …) is used, as is newfstatat(fd, "", …). Change-Id: I03b9dc5118d7a47514abef82c4a577e8362fbb4d
2022-07-08ripple/minitrace: convert openat dirfd correctlyedef
Our conversion always mangled it, *and* our comparison was inverted, so both bugs remained hidden. Change-Id: Ied63822001c8700fc71c89ec16d18036fbc33972
2022-06-19ripple/minitrace: fix syscall ABIV
The fourth argument is passed in r10, not rcx, which is merely clobbered by syscalls. Change-Id: I0c7210c621f6955deccf21348ce6f495424555cc
2022-06-19Make rustfmt.toml globaledef
Change-Id: I9ef820d2c22d54c6d8d6b259c2eea3f27d6459ac
2022-06-19ripple/fossil: box the bao decoderedef
Shuffling 3k around on the stack doesn't make anyone happy. Change-Id: I444fc22267380d9b99ca63ca148b9a9e85238b5a
2022-06-17ripple/minitrace: add set_tid_address, set_robust_list, and getrandomV
With this, minitrace has all the syscalls needed to run cc1. Change-Id: Iaeef58769f69d64e192af2270eb520e891daec94
2022-06-13ripple/fossil: use std::os::unix::preludeedef
We were accidentally grabbing things from the prelude module already, and this is the cleaner fix. Change-Id: I2c6b669164df11f467eae495d109e096eb267b59
2022-06-12ripple/fossil/chunker: use hex_literal rather than hex escapesedef
A little more explicit, and a bit more readable. Change-Id: Id462c46236e1de547aabd36409260bd1c99f6f88
2022-06-12ripple/website: add SPDX annotationsedef
We haven't picked a license for our web content yet, so this is LicenseRef-NONE for now. Change-Id: Iabfc35860cb8ad0025624161214b1cbb6574e0c5
2022-06-12ripple/shell.nix: provide a wrapper for SUID fusermount(1)edef
fusermount(1) gets shadowed by pkgs.fuse, but we actually need the SUID-root one in the system PATH. This adds a wrapper script that hunts down a SUID-root binary from PATH. Change-Id: Icc5c6789d7b74bf8f6e3c50529333eb6b894527f
2022-05-10ripple/fossil: permit importing trees from git reposedef
Change-Id: I8329f14bddaaa2d141e82c087821e4602bd1259a
2022-05-05ripple/fossil/mount: document how . and .. workedef
Change-Id: I6c4d471b2840613d30ee95efe14547f2f9c0db6b
2022-05-05ripple/fossil/Cargo.toml: sort depsedef
Change-Id: I0710d80e34bcad1d4b1406731f2d790a0e6972f4
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: fix clippy nitedef
Change-Id: I2c9b2a15ac066ec2295d54665afd301f396efdc1
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 digest_from_str and digest_stredef
These decode digests to and from zbase32 for user-facing uses. Change-Id: Ibd2db960044a97812d18d1a3c107521d78bd7f24
2022-05-03ripple/fossil/chunker: clean up SAFETY commentsedef
stdlib code seems to place these before the blocks, so let's copy their style. Change-Id: Ic77ed43bc8c6807c5ddb126e624f263f8bca5b66
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: expose add_directoryedef
Change-Id: I8e976279bd7aaaaf325129dc5c68a6ca5c750dc6
2022-05-03ripple/fossil: don't recursively fsyncedef
`add` takes about 10 seconds to run on a full LLVM tree, unless it were to spend 4 minutes mostly waiting for a series of tiny fsyncs. It did. Change-Id: I492604bae68e3472f8626a112a33d023947e0e86
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
2022-05-02ripple/fossil/chunker: iterate smarteredef
This drops the manual `len <= MIN_CHUNK_SIZE` check, and instead combines it into acquiring the to-be-scanned chunk. The pointer-based design doesn't need the iterator to be enumerated from the start of the buffer, so we don't need to use take/skip. Throughput improves about 5%. Change-Id: Ic430c7afde68bf1acfba1a2137a0b8ac064176ea
2022-05-02ripple/fossil/chunker: use const computation for DISCRIMINATORedef
While `const fn` isn't permitted float computation, regular `const` is. This deals with LLVM's reluctance to inline discriminator_from_average, without forcing us to hardcode a magic number. Change-Id: Ibdbfa4c733468517a2feff1ec0deedd1d9b70d47
2022-05-02ripple/fossil/chunker: remove hasher initialisation bounds checkedef
We already check for `self.buffer.len() <= MIN_CHUNK_SIZE`, but LLVM doesn't seem to notice. This boosts throughput by 35%. Change-Id: I1a0e07d276dcc285f8dec3149a629cb6e865c286
2022-05-02ripple/fossil/chunker: factor out Chunker::cutedef
Change-Id: I4fed55703cd02833f377ed0bbc659f3fcfdb949f
2022-05-02ripple/fossil/chunker: eliminate indexing and bounds checksedef
This improves performance by ~12%. Change-Id: I5612b624da77b138fcfb44cbb439b0106580ed70
2022-05-02ripple/fossil/chunker: hardcode the discriminatoredef
This improves performance by ~17%. I had *expected* that rustc would have reduce it to a constant already, but alas. Change-Id: I5c15fe90244da64498d2d6562262db58242ffb24
