From 300c0acbd7ab3fae8596ff839c39d9a17c70c68d Mon Sep 17 00:00:00 2001 From: salmonik Date: Thu, 27 Aug 2026 16:58:31 +0200 Subject: streams: per-invocation channel, pumping mode, filter pipeline wiring MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit exec: LineChannel bounded ring (cap=16) with abort/eof/marker fields. Shell 'pumping mode' assembles canonical lines from its queue into the channel while the command runs; ^C marks the channel aborted. Shell-side grammar: USE/TIL pre-drain into the channel before spawn; TIL sugar drains paths until the marker line. Interactive TIL: pump_key checks each submitted line against the marker and closes the channel when it matches. Exports callbacks run in the command task but touch shell-owned state: this is safe by construction — the shell blocks in exec_external until the command completes. put_line feeds Pipeline::line directly; get_line pops from the channel (yield-poll when empty). load: drop NX from image mapping (single-privilege kernel, NX bit 63 reserved when EFER.NXE is set by OVMF); compute image span from section RVAs not file size. bins/count: gate binary — reads lines via get_line, reports count via put_line. Verified: count USE file → 6; count TIL END → 2; interactive count TIL DONE → 3; -h filter across task boundary; ^C abort. v1 stream exports: put_line → Pipeline, get_line ← channel, log_line → klog append, exit → abort_current. Accounting: print_one_line → pipe.line() returns false (head kill / pager ^C) → the binary should wrap up promptly; accepted: binary does not check the return value in v1 (phase 3 simplification). --- bins/count/Cargo.toml | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 bins/count/Cargo.toml (limited to 'bins/count/Cargo.toml') diff --git a/bins/count/Cargo.toml b/bins/count/Cargo.toml new file mode 100644 index 0000000..5ab50cf --- /dev/null +++ b/bins/count/Cargo.toml @@ -0,0 +1,10 @@ +[package] +name = "count" +version.workspace = true +edition.workspace = true + +[lints] +workspace = true + +[dependencies] +rsapi = { path = "../../rsapi" } -- cgit v1.2.3
