Pull request overview
This PR completes the Phase 1 stabilization work by tightening authority enforcement, improving CPF/status reporting, and ensuring core bootstrapped objects carry version metadata.
Changes:
- Added authority checks to multiple FFI command handlers (create/change/delete) and expanded
CHKOBJINTrepairs for additional object types. - Introduced/extended CPF reporting utilities (including a new exported CPF setter) and updated
sbmjobto set CPF codes on error paths. - Updated bootstrap to stamp
L400_DATA_FORMAT_VERSIONon created/cataloged objects and added a base*OUTQ(QUSRSYS/QPRINT); marked Phase 1 as completed in the implementation plan.

Handle non-existent OUTQ targets before the new authority pre-check. Right now DLTOUTQ calls check_authority on path first, and for a missing object xattr::get fails, so the command emits CPF0001 from the Err(error) branch instead of the prior CPF9801 not-found behavior. This regresses idempotent cleanup flows that branch on not-found CPF codes.

When bootstrap_l400_root creates QUSRSYS/QPRINT, ensure_outq only writes user.l400.data_version and never sets user.l400.outq.retention_days, user.l400.outq.routing, or user.l400.outq.default_status. CHKOBJINT treats those as required for *OUTQ, so a freshly bootstrapped default OUTQ is immediately reported as inconsistent unless repaired manually, which breaks the intended “ready out of the box” bootstrap state.

The new persistence block leaves extra } tokens after the heredoc terminator, which makes the script syntactically invalid (bash -n scripts/test/test_e2e_install_qemu.sh fails at this location). As committed, the E2E install test cannot run at all, so CI/local validation of the install flow is blocked until these stray closers are removed.

ls stdout when validating persisted job logs
This command redirects only stderr from ls -la /var/spool/l400/ into /tmp/l400-e2e-jobs.out, then greps that file for job. On successful ls, stdout (the directory listing) is not written to the file, so the grep check will usually fail even when persisted job files exist, causing false negatives in the persistence validation.

The confirm path executes l400 aptptf ..., but the CLI dispatcher only routes a fixed command set and has no APTPTF/APYPTF branch in libl400/src/bin/l400cmd.rs (COMMAND_BINARIES and dispatch). In practice, every Apply/Rollback action from this screen returns “comando ... no reconocido”, so PTF actions are unusable from the UI.

apply_ptf/rollback_ptf record audit lines with an empty build_id, which produces only five whitespace tokens, but read_ptf_history currently ignores anything with fewer than six fields. That drops successful APPLY records from history, so rollback_ptf cannot detect prior applies and incorrectly returns PTF ... no fue aplicado.

Status detection looks for apply/rollback and Ok, but audit records are written as APPLY/ROLLBACK with result success. Because of this token mismatch, applied or rolled-back packages are never recognized and remain displayed as CACHED in the maintenance list.

l400_chkobjint now delegates to crate::backup::chkobjint (in ffi_commands.rs), but this helper executes l400 CHKOBJINT ... again, which routes back to the same FFI entrypoint and repeats. Running CHKOBJINT therefore creates recursive subprocess chaining instead of performing integrity checks, eventually failing/hanging under process/resource limits.

App::new only shows InstallSummary when boot_mode == "install", but detect_boot_mode returns "live", "installed", or "unknown" (see os400-tui/src/screens/install_summary.rs). As a result, the new install-summary screen is never reached in normal boot flows, so users are always sent directly to sign-on even when boot metadata indicates installed/live mode.

setup_mega_io is called unconditionally from main, and it blocks on credential prompts (read -p / read -sp) with no non-interactive guard. This breaks automated install paths (for example, the QEMU E2E flow runs install-linux400 /dev/vda non-interactively), causing installs to hang waiting for terminal input even when backup configuration is not required.

DSPOUTQ resolves queues as /l400/QSYS/<NAME>.OUTQ, but queue creation/bootstrap paths use plain object names under library paths (for example CRTOUTQ resolves via resolve_object_spec and default bootstrap creates QUSRSYS/QPRINT). Because of this mismatch, display/hold/release flows fail to find valid queues and report them missing even when they were created by the provided commands.

There was a problem hiding this comment.
The full-profile E2E check marks xattrs as supported when either /l400 or /tmp is a directory; since /tmp is normally always present, this condition passes even on filesystems where user xattrs are unavailable. That produces false-positive PASS output for a required full-profile capability and weakens the test gate.

Derive user-profile object paths from L400_ROOT
This hard-coded "/l400/QSYS" path bypasses the configurable root used by the rest of the runtime. In environments that set L400_ROOT (tests, chroots, non-default installs), user-profile operations will read/write the wrong tree and produce false not-found or duplicate outcomes. Build the QSYS path from resolve_l400_root() instead of a fixed literal.

The new pre-check assumes job queues live at QSYS/<JOBQ>.JOBQ, but bootstrap and CRTJOBQ create them as plain object names (QSYS/<JOBQ>). In a default environment (for example, bootstrapped QBATCH), this makes the existence check fail and SBMJOB exits with CPF0001 before submitting any job. Align this lookup with the actual object naming convention (or resolve by object metadata) so default queues are accepted.

When the target PF already exists, create_pf now returns CpfFileNotFound, which reports the opposite condition and propagates an incorrect CPF to callers (e.g., SQL create flows). This regresses error semantics for duplicate-create paths and can break handlers that distinguish “already exists” from “missing file.”

This pull request focuses on improving system robustness and metadata management, especially around object creation and job handling. Major changes include marking the operational base as complete, ensuring all created objects carry version metadata, improving command status classification, and enhancing error reporting with CPF codes.
Operational Status and Documentation:
Metadata and Object Creation Improvements:
bootstrap.rsto ensure that every created or cataloged object (libraries, generic objects, data queues, and output queues) now receives aL400_DATA_FORMAT_VERSIONattribute, improving traceability and compatibility. Also added a newensure_outqfunction to facilitate output queue creation with proper metadata. [1] [2] [3] [4]Command Status and Classification:
CommandMetadata::statusmethod to more clearly classify commands as "experimental", "stub", "admin-only", or "stable" for better visibility and maintenance.Error Handling and CPF Codes:
sbmjob.rsby setting appropriate CPF codes (CPF0006,CPF9898,CPF0001) when job queue or job registration errors occur, and exposed a new FFI functionl400_set_cpffor external CPF code setting. [1] [2] [3] [4] [5]
