v1.14.31c's matrix jobs failed on Upload digest with GHESNotSupportedError
— Gitea Actions doesn't support actions/upload-artifact@v4+.
Separately, build-omos arm64 hung silently for 12 min in Set-up job,
likely catthehacker pull contention between concurrent matrix children.
Rather than downgrade artifacts to @v3, collapse the matrix entirely.
docker/build-push-action@v7 with platforms: linux/amd64,linux/arm64
publishes a proper multi-arch manifest in one job, so the
artifact-passing and imagetools create merge dance only existed to
support a matrix split we no longer need.
The matrix was designed around load: true disk exhaustion (v1.14.30b),
but push-by-digest streams straight to the registry with fundamentally
different disk profile. Reclaim step gives enough headroom for the
combined amd64+arm64 push case.
Workflow: 7 jobs → 5. docker-publish.yml: 263 → ~110 lines of YAML.
Also:
- timeout-minutes: 90 on build jobs so hung builds fail explicitly
- BUILDKIT_PROGRESS=plain at workflow level for line-by-line arm64 logs
- AGENTS.md §CI quirks documents the Gitea-specific traps
(upload-artifact@v3-only, dash-not-bash, build-push-action@v7
multi-arch convention, reclaim requirement)
The mempalace Python package ships a 'mempalace-mcp' console entry
point; 'uv tool install' places it on PATH as a shim whose shebang
points at the isolated venv's Python. Our hand-rolled wrapper at
/usr/local/bin/mempalace-mcp-server was duplicating what uv installs
for free — one less file to maintain.
Fixes the MCP error users saw after the v1.14.28b → v1.14.29 upgrade
path: custom opencode.json files typically had the pre-v1.14.29
command ['python3', '-m', 'mempalace.mcp_server'] which worked with
the old pip install but fails silently after the uv-tool migration
because system python3 cannot import from the venv. Opencode surfaced
this as 'MCP error -32000: connection closed'.
- generate-config.py now emits ['mempalace-mcp'] and keys its detect
on shutil.which('mempalace-mcp').
- Dockerfile drops 'COPY rootfs/usr/local/bin/' and the chmod of the
wrapper. Build shrinks from 30 to 29 stages.
- rootfs/usr/local/bin/ removed entirely.
- Smoke test asserts /usr/local/bin/mempalace-mcp is executable and
prints its symlink target.
- README's MemPalace section shows ['mempalace-mcp'] and explicitly
warns against the old pattern with the observed failure mode.
- CHANGELOG adds a v1.14.29c entry.
Main changes:
- Extract opencode.json generation from entrypoint-user.sh into a
standalone Python script (rootfs/usr/local/lib/opencode-devbox/
generate-config.py). Preserves the never-overwrite-existing-config
guarantee. Cuts entrypoint-user.sh from 176 to 97 lines.
- Install MemPalace via 'uv tool install' into an isolated venv at
/opt/uv-tools/mempalace/ with a /usr/local/bin/mempalace-mcp-server
wrapper, replacing the 'pip install --break-system-packages' escape
hatch. The wrapper is what generate-config.py references in the
auto-generated opencode.json. Also fix 'mempalace init' in
entrypoint-user.sh to use --yes so first-start initialization isn't
interactive (this used to hang or print prompts into the user's
terminal). Gated by INSTALL_MEMPALACE build arg (default true) so
users who don't need AI memory can shave ~300 MB.
- Sentinel-file pattern in entrypoint.sh volume-ownership loop: write
.devbox-owner after a successful chown -R, skip the recursive walk
on subsequent starts when the sentinel matches FINAL_UID:FINAL_GID.
Cuts multi-second startup costs to milliseconds on large volumes
(nvim plugins, palace data). UID changes still trigger a full chown.
- Float all GitHub/Gitea-hosted binary versions: gosu, fzf, git-lfs,
neovim, bat, eza, zoxide, uv, gitea-mcp now default to 'latest' and
resolve the newest upstream release at build time via the /releases/
latest redirect. Go (go.dev JSON feed) and oh-my-opencode-slim (npm
@latest) likewise. Intentional pins still in place: OPENCODE_VERSION,
NODE_VERSION=22, DEBIAN_VERSION=trixie-slim. Each *_VERSION ARG
accepts an explicit value to lock a specific version when needed.
- New scripts/smoke-test.sh verifies binary presence, opencode startup,
entrypoint user drop, generate-config idempotency, bun's presence-
per-variant, and image size against thresholds (2500 MB base, 3000
MB OMOS). Prints resolved component versions as its first step so
CI logs always record what got baked into a given image.
- New .gitea/workflows/validate.yml runs on push to main and PRs:
single-arch amd64 build, smoke test, DOCKER_HUB.md sync check. Tag-
triggered docker-publish.yml now smoke-tests each variant on amd64
before the full multi-arch push.
- scripts/generate-dockerhub-md.py auto-generates DOCKER_HUB.md from
README.md using explicit SECTION_RULES. --check mode fails CI when
the committed file is out of sync. Enforces the 25 kB Docker Hub
limit. Adding a new README section forces an explicit keep/drop/
replace decision.
- Remove dead INSTALL_PYTHON build arg (was a no-op since mempalace
added python3 unconditionally).
Previous phrasing treated the letter suffix as a plain alphabetical
sequence, which led to confusion about whether the first rebuild
should be 'a' or 'b'. Spell out the intent: the suffix is the build
ordinal, and the letter 'a' is reserved to mean '1st build' — which
always uses the bare tag (no letter). So letters start at 'b' for
the 2nd build, 'c' for the 3rd, and so on.
Examples for opencode version 1.14.20:
1st build: v1.14.20
2nd build: v1.14.20b
3rd build: v1.14.20c
Bump OPENCODE_VERSION ARG from 1.14.19 to 1.14.20 to track the new
upstream release on npm.
Clarify the tagging convention in AGENTS.md: the first build on a new
opencode version uses the bare 'v{opencode_version}' tag (no letter
suffix). Letter suffixes (a, b, c, ...) are reserved for container-
level rebuilds on the same opencode version (CVE fixes, doc changes,
entrypoint bugs). The previous wording implied a letter was always
required, which was never the actual behaviour.
