# Session Log: J2J Jobs Housekeeping, Watermark-to-Counter (J2J-2), SDP-Aware Deployment (J2J-3) **Date:** 2026-09-13 **Author:** GitHub Copilot CLI (Claude Sonnet 5) **Requested by:** Tom Tyler --- ## Context Started with a P4 login check and a review of `ai_dev_support/AGENTS.md`, then listed the three open J2J- jobs on the Public Depot server (J2J-1, J2J-2, J2J-3) via `ojobs` / `j2j_jobs_report.sh`. ## Work done 1. **Fixed `tools/j2j_jobs_report.sh` referencing a stale filename.** `env.sh` had been renamed to `dev_env.sh`, but the report script's `source` statement (and a `-man`-style comment) still pointed at the old name, causing a "No such file or directory" error on every run (harmless -- the rest of the script still worked -- but noisy). Fixed both references. Change **33765**. 2. **J2J-2: "Change Watermark from a file to a counter stored on the P4 server."** Reviewed the job (title only, no description body) against `bin/sync_jira_to_p4jobs.sh` and confirmed the intent was unambiguous: the JIRA sync watermark was stored in `${StateDir}/last_sync_time`, a local file tying it to one host/checkout. Proposed and implemented: - New `WatermarkCounter` config key (default `jira-sync-watermark`). - `get_watermark()` / `save_watermark()` rewritten to use `p4 counter` via the existing `p4_cmd` wrapper instead of file I/O. An unset P4 counter reads back as `"0"` (verified live against the Public Depot server) -- treated the same as "no watermark yet" for the `InitialLookbackSeconds` fallback. - Added `migrate_legacy_watermark_file()`, called from `init_state()`: seeds the counter from any pre-existing `last_sync_time` file on the first run after upgrade (only if the counter is still unset), then renames the file to `last_sync_time.migrated` so it isn't reread. - Setting/reading the counter needs only the `admin`/`super` P4 access this script's service account already requires for `p4 job -i -f` (per `check_p4_access()`) -- no new privilege grant needed. - Updated the `-man` `STATE FILES` section, the example config written by `--init`, and `docs/sync_jira_to_p4jobs_README.md` to match. - Verified: `bash -n` syntax check, `-man` text renders correctly, and `get_watermark`/`save_watermark` control flow unit-tested with a mocked `p4_cmd` (unset counter -> lookback fallback; save then get round-trips correctly). Could not test against the real Public Depot server directly under my own account -- `p4 protects -m` returns only `write` access there, and setting a counter returned "You don't have permission for this operation," which is expected/consistent with the script's own `admin`-required design. - Change **33766**. 3. **Caught a missed standing policy on my own submit.** A prior session (`SESSION_2026-09-01_p4_credentials_and_preflight_checks.md`) established: bump `declare Version="X.Y.Z"` in `sync_jira_to_p4jobs.sh` with every submit that touches it. Change 33766 touched the script but I forgot the bump. Caught it by checking `p4 filelog` before writing this log, corrected with change **33767** (3.2.0 -> 3.3.0, minor: new backward-compatible config key + storage migration, no breaking CLI/behavior change for operators). 4. Linked jobs to changelists: `p4 fix -c 33766 J2J-2` and `p4 fix -c 33767 J2J-2` (both auto-closed J2J-2, since the changelists were already submitted at fix time). 5. **J2J-3: "Deploy anywhere: Be SDP-aware not SDP-dependent for deployment."** Reviewed `sync_jira_to_p4jobs.sh` and found the runtime defaults (`ConfigFile`, `LogsDir`, `StateDir`) already fell back gracefully from SDP env vars (`P4CSBIN`/`LOGS`/`P4TMP`) to generic `/tmp`-based paths -- but four gaps undercut "deploy anywhere": - `write_example_config()` hardcoded `StateDir=/p4/1/tmp/jira_sync` (an SDP instance-1 path) in the generated example config, instead of following the same env-var-aware fallback as the runtime default. Fixed: now commented out as an example, matching the existing `P4ConfigFile` treatment. - No startup visibility into which mode was active. Added a one-line preflight log message: `Deployment mode: SDP (detected: ...)` or `Deployment mode: standalone (... using generic /tmp-based fallbacks)`. - README was written entirely around SDP paths with no standalone guidance. Added a "Standalone (non-SDP) deployment" section (with a mode-comparison table and a numbered walkthrough) and a matching `DEPLOYMENT` section in `-man`. - Fixed a misleading comment overstating `python3` as an SDP-specific dependency (it isn't -- it's a generic, near-universal one). - No breaking changes; SDP remains the first-class default. Bumped Version 3.3.0 -> 3.4.0 (minor). - Verified: `bash -n` syntax check, `-man DEPLOYMENT` section renders correctly, and the deployment-mode detection logic was unit-tested standalone (`env -i bash ...` with/without the SDP vars set). - Change **33768**, split into its own pending changelist (separate from this session log file, per Tom's request to keep `ai_dev_support/...` changes independently submittable) via `p4 change -o`/`p4 change -i` + `p4 reopen`. Linked with `p4 fix -c 33768 J2J-3` (auto-closed J2J-3). - **Changelist-description correction:** submitting via `p4 submit -c 33768` carried over a stale placeholder description ("...(work in progress)." plus a leftover "" line) from when the changelist was created. Fixed after the fact with `p4 change -u -i` (amends a submitted changelist's description; unlike `-f`, `-u` only requires being the changelist's owner, not `admin` access -- learned this from Tom after initially assuming it was unfixable without admin). 6. **Mac compatibility review** (no code changes -- verification only). Tom asked whether `sync_jira_to_p4jobs.sh` -- envisioned for the Public Depot server / an Ubuntu box -- would also work unmodified from this Mac checkout (`/Users/ttyler/pub/j2j`). Confirmed yes, and demonstrated it live: - Environment check: Homebrew `bash` 5.3.3 (not macOS-stock 3.2 -- needed for `declare -A`/`local` etc.), Homebrew `flock` (not stock on macOS; fd-based `flock -n 9` usage tested directly and works), and Homebrew `python3` 3.14.5 all present. - The script's two BSD/GNU fallback pairs (`date -d ... || date -r ...` and `stat -c ... || stat -f ...`) were tested directly on this Mac's stock BSD `date`/`stat` -- confirmed the GNU-style branch fails as expected and the BSD fallback branch succeeds. - `P4ConfigFile`'s default is derived from the script's own `BASH_SOURCE` location (`AppHome/secure/...`), not cwd or an SDP env var, so it "just works" from this checkout regardless of working directory. - Ran a live, read-only dry run from `/Users/ttyler/pub/j2j` using the pre-existing `secure/dryrun_test.cfg` (from the 2026-08-31 first-dry- run session): `bash bin/sync_jira_to_p4jobs.sh -C secure/dryrun_test.cfg -max 2 -v 4` (no `-y`, so no P4 writes were made). It connected to real JIRA, fetched real SDP issues, previewed two job upserts (`[NoOp] Would upsert: ...`), and read the new P4-counter watermark cleanly via the `bot_p4jira` service account (`P4 access level: admin.`) -- end-to-end confirmation that the J2J-2 watermark-counter change also works from this Mac. - One caveat noted, not a bug: `ConfigFile`'s own *default* path still falls back to `/p4/common/site/bin/...` (an SDP path that can't exist on a Mac) when `P4CSBIN` is unset -- `-C` must be passed explicitly on this platform. Already covered by the J2J-3 "Standalone (non-SDP) deployment" README section added this session. ## Outstanding items / notes for next session 1. J2J-1 (P4Blog idea, filed 2026-08-30) and the `-batch` option design (captured in `SESSION_2026-09-01_p4_credentials_and_preflight_checks.md`) remain open/unimplemented. 2. J2J-2 and J2J-3 are both closed as of this session (changes 33765-33768). 3. No live (`-y`) run of `sync_jira_to_p4jobs.sh` has been done yet from any host, Mac or otherwise -- still previews only. Recommended next step remains the smallest possible blast radius (`-y -max 1`) when ready, per the 2026-09-01 session log.
