2026-04-24task a8: move all binaries under ./cmd/<name>/main.goPaul Buetow
Relocates the two non-canonical main packages so every binary in the repo lives at ./cmd/<BINARY>/main.go: - tools/filewriter/ -> cmd/filewriter/ - integrationtests/cmd/ioworkload/ (20 files) -> cmd/ioworkload/ Consumers updated: - Magefile.go: workloadSourcePath now ./cmd/ioworkload - integrationtests/README.md: structure note points at ../cmd/ioworkload Files moved with git mv so git log --follow history is preserved. cmd/ior/main.go was already canonical and is untouched. Verified: mage build produces the ior binary; go build ./cmd/... builds filewriter and ioworkload; go test ./cmd/ioworkload passes; go vet ./cmd/filewriter ./cmd/ioworkload is clean.

2026-02-21Split ioworkload scenarios.go into per-category filesPaul Buetow
Split the 2494-line scenarios.go monolith into 14 focused files by syscall category: open, readwrite, close, dup, fcntl, rename, link, unlink, dir, stat, sync, truncate, iouring, plus the slimmed-down scenarios.go containing only the registry map, makeTempDir, and crash. Extracted rawLink, rawSymlink, rawReadlink helpers in scenario_link.go to reduce code duplication in linkBasic. Task: #349 (Go best practices: split oversized scenarios file) Amp-Thread-ID: https://ampcode.com/threads/T-019c81c6-e1b6-747a-9144-40f6be997e60 Co-authored-by: Amp <amp@ampcode.com>
2026-02-21Add negative integration tests for io_uring syscalls (EBADF)Paul Buetow
Add two new scenarios and tests: - iouring-enter-ebadf: io_uring_enter with invalid fd 99999 - iouring-register-ebadf: io_uring_register with invalid fd 99999 Both verify ior captures the tracepoint even when the syscall fails.

2026-02-21Add negative integration tests for truncate syscalls (task 348)Paul Buetow
Add two negative test scenarios: - truncate-enoent: SYS_TRUNCATE on nonexistent file, expects ENOENT - truncate-ftruncate-ebadf: SYS_FTRUNCATE on invalid fd 99999, expects EBADF Both verify ior captures tracepoints even when syscalls fail.

2026-02-21Add negative integration tests for sync syscalls (task 348)Paul Buetow
Add three EBADF scenarios testing ior's ability to capture sync-related tracepoints even when the underlying syscall fails: - sync-fsync-ebadf: fsync on invalid fd, expects enter_fsync - sync-fdatasync-ebadf: fdatasync on invalid fd, expects enter_fdatasync - sync-file-range-ebadf: sync_file_range on invalid fd, expects enter_sync_file_range Amp-Thread-ID: https://ampcode.com/threads/T-019c81b4-216a-732c-90b1-e6771e27ed75 Co-authored-by: Amp <amp@ampcode.com>
2026-02-21Add negative integration tests for stat syscalls (task 348)Paul Buetow
Add three negative test scenarios for stat-family syscalls: - stat-enoent: SYS_STAT on nonexistent file (ENOENT) - stat-access-enoent: SYS_ACCESS on nonexistent file (ENOENT, since tests run as root and EACCES is bypassed) - stat-fstat-ebadf: SYS_FSTAT on invalid fd 99999 (EBADF) Each scenario verifies that ior captures the tracepoint on syscall entry even when the syscall fails.

2026-02-21Add negative integration tests for dir syscalls (task 348)Paul Buetow
Add three negative test scenarios for directory operations: - dir-mkdir-eexist: SYS_MKDIR on existing directory (EEXIST) - dir-chdir-enoent: SYS_CHDIR to nonexistent directory (ENOENT) - dir-getdents-ebadf: SYS_GETDENTS64 with invalid fd (EBADF) All use raw syscalls to hit exact tracepoints. Tests verify ior captures events even when syscalls fail (entry-side capture). Amp-Thread-ID: https://ampcode.com/threads/T-019c81ab-0d62-726e-b859-91b4898be6fe Co-authored-by: Amp <amp@ampcode.com>
2026-02-21Add negative integration tests for unlink syscalls (task 348)Paul Buetow
Add three negative test scenarios for unlink syscall family: - unlink-enoent: SYS_UNLINK on nonexistent file (ENOENT) - unlink-rmdir-notempty: SYS_RMDIR on non-empty directory (ENOTEMPTY) - unlink-unlinkat-enoent: SYS_UNLINKAT on nonexistent file (ENOENT) All scenarios use raw syscalls to hit exact tracepoints and verify ior captures them on entry even when the kernel returns an error.

2026-02-21Add negative integration tests for link syscalls (task 348)Paul Buetow
Add three negative scenarios and tests: - link-enoent: hard link to nonexistent source (ENOENT) via raw SYS_LINK - link-symlink-eexist: symlink where target already exists (EEXIST) via raw SYS_SYMLINK - link-readlinkat-einval: readlinkat on non-symlink file (EINVAL) via SYS_READLINKAT All use raw syscalls to hit exact tracepoints. ior captures on syscall entry, so even failed syscalls have their arguments recorded.

2026-02-21Add negative integration tests for rename syscalls (task 348)Paul Buetow
- rename-enoent: rename nonexistent file via SYS_RENAME (ENOENT) - rename-noreplace: renameat2 with RENAME_NOREPLACE on existing target (EEXIST) Both verify ior captures tracepoints on entry even when syscall fails.

2026-02-21Add negative integration tests for fcntl syscalls (task 348)Paul Buetow
Add two negative scenarios: - fcntl-invalid-fd: calls SYS_FCNTL F_GETFL on invalid fd 99999 (EBADF) - fcntl-dupfd-max: calls F_DUPFD with minfd=1<<30 beyond RLIMIT_NOFILE (EINVAL) Both verify ior captures enter_fcntl tracepoints even when syscalls fail.

2026-02-21Add negative integration tests for dup syscallsPaul Buetow
Add three negative test scenarios for dup syscalls: - dup-invalid-fd: dup on invalid fd 99999 (EBADF) - dup2-same-fd: dup2(fd, fd) no-op case (POSIX documented behavior) - dup3-invalid-flags: dup3 with 0xBAD flags (EINVAL) All verify ior captures the tracepoint even when the syscall fails, since BPF reads arguments on syscall entry before execution.
