- Introduced `StreamWriter` with configurable block and line buffering policies across builtins.
- Updated pipeline stages and compound commands to execute concurrently as tasks.
- Replaced Linux splice and local stream wrapping with generic `Write` streams and explicit flushing.
- Added regression and streaming smoke tests to verify concurrent output and prevent deadlocks.
Addresses a broad audit of built-in shell utilities against their real counterparts: timeout gains signal delivery, -s/-k/--preserve-status/--foreground/-v, and GNU exit codes; diff defaults to normal format and gains -w/-b/-B/-i/-c/-x/-L/-s/--strip-trailing-cr and proper -r gating; find fixes -newerXY timestamp comparison direction, anchors -regex to whole paths, and gains BSD -perm +mode, -type lists, -size T/P suffixes, -E/-x/-s flags; date gains BSD -r epoch, -v adjustments, -j -f strptime, and non-greedy -I; tail/head accept obsolete -N/+N at any position with any file count; rg resolves case flags by last occurrence and gains --path-separator and clean -0 output; stat prints integer epochs for %X/%Y/%Z and gains BSD -s/-x/-t; cksum is registered as a builtin; truncate implements -o/--io-blocks and b/= size suffixes; sleep/timeout accept infinity; yes/errno/kill accept hyphen-prefixed operands; nohup -- cmd no longer runs --; which gains BSD -s.
- Add comprehensive Nix flake definitions, derivations, modules, and CI workflows.
- Update tests and executables to resolve binaries from PATH rather than absolute paths.
- Ensure byte reproducibility and zeroed timestamps in embedded dashboard archives.
- Add handling for Nix-managed installations in CLI update checks.
Routed sed -f script files and the in-script r/w/s///w file paths through brush-core's shell path normalizer, so /c and /mnt/c aliases open the live Windows drive instead of a phantom current-drive path. Added a Windows -f regression.
Fixes#8355
Normalized utility operands through brush-core's shared shell path resolver so /c and /mnt/c aliases address the live Windows drive. Added Windows-only regression coverage at the Host boundary.
Fixes#8355
Abort shell-internal background tasks when their owning session is dropped, and propagate task abortion into blocking utility cancellation so infinite writers stop.
Fixes#8341
- Synced pi-builtins bazel crate_features with cargo's resolved default
set: bazel features are literal, so the meta-features never expanded
and the procs/rg cluster (nohup, pgrep, pidwait, pkill, proc-match,
ps, rg, sleep, timeout, top) was silently compiled out, leaving the
process builtins unregistered under bazel and failing pi-shell tests.
- Repaired windows compilation of pi-builtins: cfg-gated the
uucore::mode import in mkdir, imported std::env in sort's non-unix
locale probe, mapped ProcInfo::pid through a closure in kill, brought
MetadataExt into scope in wc, and replaced stat's unstable
windows_by_handle metadata with a stable GetFileInformationByHandle
query (volume serial, link count, file index, no-dereference aware).
- Imported HashSet for pi-shell's windows-only PATH merge.
- Added a clippy-ported bazel config + CI bucket so pi-builtins keeps
its manifest-declared clippy allows under the bazel aspect while rustc
warnings stay denied, and zeroed the remaining windows-target rustc
warnings (unused params/imports in find, mv, rm, proc_match, ps).
- Added util.procs to the bazel crate_features: cargo resolves the
builtin.kill -> util.procs implication automatically, but bazel
crate_features are literal, so kill.rs failed with E0432 on
proc_snapshot once HostProcesses became unconditional.
- Imported std::os::fd::AsFd in the linux/android splice path of the wc
builtin (E0405); the import is target-gated like its callers.
- Verified with cargo check -p pi-builtins --no-default-features using
the exact bazel feature list on both the host and (via zig cc)
x86_64-unknown-linux-gnu targets.
- Added `HostProcesses` snapshot and `ChainNode` validation to track ancestry and prevent pid recycling.
- Updated process matching and signal handling to refuse signalling the shell or its ancestor processes.
- Added regression tests verifying that kill builtins safely block ancestor targeting while permitting unrelated processes.
- Added the `smallvec` dependency to support efficient process snapshot tracking.
