rsim#291 added the ORA-01805 workaround to `ruby_head.yml`. The same root cause -- `gvenzl/oracle-free:latest` shipping a newer timezone-data version than the "latest" Instant Client embeds -- affects every other workflow that combines that image with ruby-oci8: - `truffleruby.yml`: failing on schedule since 2026-05-09 with `ORA-01805` from `ocidatetime.c:119 in oci8lib_truffleruby.so` (https://github.com/rsim/ruby-plsql/actions/runs/25710673905). - `test.yml`: not yet run against the updated image (latest run was 2026-05-08, image upgrade landed on 05-09); will fail on the MRI matrix slots on the next push/PR. - `test_gemfiles.yml`: same situation as test.yml. Apply the same dynamic copy-and-set-ORA_TZFILE step immediately after `Create database user`. `jruby_head.yml` is excluded because it uses the JDBC driver and is not affected (confirmed still green on schedule).

Apply the workaround from #292 to the dev container. CI fixed `ORA-01805: possible error in date/time operation` by copying the running Oracle server's `timezlrg_*.dat` into the Instant Client's `oracore/zoneinfo/` and pointing `ORA_TZFILE` at it. The dev container combines `gvenzl/oracle-free:latest` with the Instant Client installed via the app `Dockerfile`, so it is exposed to the same drift and benefits from the same fix. PR #301 ported the workaround by adding the `docker-outside-of-docker` feature and copying the file from inside the dev container via `docker exec` / `docker cp`. That approach fails on Dev Containers 0.459.0 with the `mcr.microsoft.com/devcontainers/base:trixie` base image because Debian trixie removed `moby-cli`: (!) The 'moby' option is not supported on Debian 'trixie' because 'moby-cli' and related system packages have been removed from that distribution. ERROR: Feature "Docker (docker-outside-of-docker)" failed to install! Move the copy to the host, where Docker is already available. Mirrors rsim/oracle-enhanced#2799. - `.devcontainer/initializeCommand.sh` (new) -- pull `gvenzl/oracle-free:latest`, then extract `$ORACLE_HOME/oracore/zoneinfo/timezlrg_*.dat` from an ephemeral container into `.devcontainer/tzdata/` on the host. No DB start, no readiness wait -- the file ships in the image. - `.devcontainer/devcontainer.json` -- `initializeCommand` now runs the new script (it previously did the inline `docker pull`). The `docker-outside-of-docker` feature, added in #301 and never merged to master, stays absent. - `.devcontainer/docker-compose.yml` -- bind-mount `.devcontainer/tzdata` read-only at `/opt/tzdata` inside the `app` service. - `.devcontainer/postCreateCommand.sh` -- set `ORA_TZFILE` from `/opt/tzdata/timezlrg_*.dat` and persist it via `/etc/profile.d/ora-tzfile.sh` so interactive shells and `bundle exec` runs pick it up. - `.gitignore` -- ignore `.devcontainer/tzdata/`. No `docker-outside-of-docker` feature, no `/var/run/docker.sock` bind, and no network access during the dev container build. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
#291 added the ORA-01805 workaround to
ruby_head.yml. The same root cause —gvenzl/oracle-free:latestshipping a newertimezlrg_*.datthan the "latest" Instant Client embeds — affects every other workflow that combines that image with ruby-oci8:truffleruby.yml: failing on schedule since 2026-05-09 withORA-01805fromocidatetime.c:119 in oci8lib_truffleruby.so(run 25710673905).test.yml: not yet run against the updated image (latest run was 2026-05-08, image upgrade landed on 05-09); will fail on the MRI matrix slots (4.0,3.4,3.3) on the next push/PR.test_gemfiles.yml: same situation astest.yml.Apply the same dynamic copy-and-set-
ORA_TZFILEstep immediately afterCreate database user, identical to #291.jruby_head.ymlis excluded because it uses the JDBC driver and is not affected (confirmed still green on schedule).Stacked on top of #291 in spirit (same fix, same root cause) but contains an independent file set, so the two can land in either order.
