# Session Log — 2026-05-21

Work on `trim_excess_metadata.sh`. Bumped to **v1.12.0**.

## Ask

1. Review the script.
2. Implement enhancement: don't delete labels/groups/clients/branches owned by a kept user.
3. General review — flag obvious bugs and suggest fixes.
4. Add a count-rich summary at the end.
5. Ignore intentionally incomplete features (Streams, Jobs and Fixes).

## Decisions

- **Owner-based keep**: applied to clients, branches, labels only. Groups intentionally **excluded** — they have multi-valued `Owners:` and user opted to keep the rule simple. Groups are kept only via the `keep_groups.txt` file.
- **Scope of bug fixes**: do #1, #2, #6 from my review. Skip #3.
  - #3 (the asymmetric "No X detected" being `errmsg` vs `msg`) is **intentional**. In the context of this script, a server with zero submitted changes or zero local/remote/stream depots means something is very wrong upstream — those should remain errors. Do not normalize them.

## Changes made

### Enhancement (owner-based keep, Phases 2/3/4)
- After the existing keep-file check, look up `Owner:` via `p4 -ztag -F %Owner% <spec> -o <name>`. If the owner is in `KeepUsersFile`, skip deletion and bump `*KeptByOwner`.

### Bug fixes
- **#1: Unsafe grep anchors.** All keep-file membership checks switched from `grep -q "^$Name$"` to `grep -Fxq -- "$Name" "$KeepFile"`. Affects Phases 2, 3, 4, 5, 7. Avoids regex injection from spec names containing `.`, `[`, `*`, etc.
- **#2: Phase 11 depot pipeline bug.** Old form `p4 depots | grep ... > TmpFile` inherited `grep`'s exit status, so a zero-match grep falsely triggered `"Could not get list of depots."` Rewritten: capture `p4 depots` first, filter `local|remote|stream` types inside the loop. New post-loop check fires `errmsg "No local/remote/stream depots detected."` if nothing of the right type was found.
- **#6: Self-delete preflight.** New check after access-level verification: fetches the operating P4 user via `p4 -ztag -F %userName% info` and aborts during preflight if that user is missing from `KeepUsersFile`. Prevents Phase 5 from deleting the script's own running user mid-run.

### Cosmetic
- `-man` text had two "Phase 9" lines. Streams now correctly listed as **Phase 8**.

### Documentation
- `-man` "FILES" section gained a paragraph explaining the owner-based keep behavior, including the group exception.

### Summary rework (replaces the trailing block)
Per-type counts now printed before the final pass/fail line:
- LDAP specs: Deleted, Failed
- Clients: Total examined, Ignored (non-empty view), Kept (keep file), Kept (owned by kept user), Deleted, Failed
- Branches: same shape as Clients
- Labels: same shape as Clients
- Users: Total, Kept, Deleted, Failed
- Shelved changelists: Deleted, Failed
- Groups: Total, Kept, Deleted, Failed
- Submitted changelists: Delete attempts (only empties succeed)
- Depots: Total examined, Empty, Non-empty (ignored), Deleted, Failed

In Dry Run mode the "Deleted" label switches to "Would delete" automatically. Note: `cmd()` returns 0 in NoOp mode without acting, so dry-run "Failed" counts will be 0 — that's working as intended.

## Validation
- `bash -n` clean.
- `shellcheck` clean.

## Open items before submit
- Regenerate the doc file: `./trim_excess_metadata.sh -man > trim_excess_metadata.command_summary.txt`
- User to test (Dry Run first, then Live).

## P4 status going into testing
- `trim_excess_metadata.sh` opened for edit.
- `trim_excess_metadata.command_summary.txt` opened for edit (still to regenerate).
- `trim_excess_metadata.sh.bak` not on client — untouched.
