Key pieces: - Rocky Linux 8 container running --privileged (required to disable transparent hugepages, which DAOS's SPDK housekeeping needs even with a pure-RAM storage tier). - test/scripts/daos_server.yml.in: RAM-emulated SCM storage tier sized and configured for small/CI hosts (system_ram_reserved lowered, scm_hugepages_disabled, nr_hugepages fixed). - test/scripts/daos_pool.sh.in: rewritten for the modern dmg CLI syntax, polling for engine join and pool queryability before signaling readiness to the test driver, to fix races where the harness would start the client before the pool was actually usable. - Excludes 3 known, tracked failures (h5_test_testhdf5, h5_partest_t_bigio, h5vl_ext_h5daos_test_metadata_parallel) so CI stays green on everything that's actually been verified so far - see the PR description for root-cause details on each. - .gitmodules: test/vol temporarily points at the brtnfld/vol-tests fork branch pending HDFGroup/vol-tests#67 merging; revert to HDFGroup/vol-tests once that lands. --- .github/workflows/ci.yml | 122 +++++++++++++++++++++++++++++++- .gitmodules | 5 +- test/CMakeLists.txt | 10 ++- test/scripts/daos_pool.sh.in | 41 ++++++++++- test/scripts/daos_server.yml.in | 18 ++++- 5 files changed, 189 insertions(+), 7 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index e03b043..c06c276 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -27,7 +27,10 @@ jobs: runs-on: ubuntu-latest env: - CLANG_FORMAT_VERSION: 13 + # clang-format-13 is no longer packaged on current ubuntu-latest + # (Ubuntu 24.04) runners; 14 is the oldest still available and + # closest to the original, minimizing reformatting-rule drift. + CLANG_FORMAT_VERSION: 14 steps: - name: Checkout source @@ -55,3 +58,120 @@ jobs: if: github.event_name == 'pull_request' run: test/scripts/gh_format.sh origin/${{ github.base_ref }} + daos-test: + runs-on: ubuntu-latest + + container: + image: rockylinux:8 + options: --privileged + + continue-on-error: ${{ matrix.hdf5_ref == 'develop' }} + + strategy: + fail-fast: false + matrix: + hdf5_ref: [hdf5_1.14.6, develop] + + env: + DAOS_REPO_URL: https://packages.daos.io/v2.6/EL8/packages/x86_64/daos_packages.repo + DAOS_GPG_KEY_URL: https://packages.daos.io/RPM-GPG-KEY + + steps: + - name: Install build prerequisites + run: | + dnf install -y epel-release + dnf groupinstall -y "Development Tools" + dnf install -y cmake git wget mpich mpich-devel libuuid-devel psmisc + echo "/usr/lib64/mpich/bin" >> "$GITHUB_PATH" + echo "LD_LIBRARY_PATH=/usr/lib64/mpich/lib:$LD_LIBRARY_PATH" >> "$GITHUB_ENV" + + - name: Install DAOS (server, client, admin, devel) + run: | + wget -O /etc/yum.repos.d/daos-packages.repo "$DAOS_REPO_URL" + rpm --import "$DAOS_GPG_KEY_URL" + dnf install -y daos-server daos-client daos-admin daos-devel + + - name: Disable transparent hugepages + run: | + echo "Before: $(cat /sys/kernel/mm/transparent_hugepage/enabled)" + echo never > /sys/kernel/mm/transparent_hugepage/enabled + echo "After: $(cat /sys/kernel/mm/transparent_hugepage/enabled)" + + - name: Mount /dev/hugepages + # We run with no NVMe/bdev tier and nr_hugepages=0, but daos_server's + # SPDK housekeeping still unconditionally tries to clean up hugepages + # at engine start/stop and logs a scary (but harmless) "ERROR:" line + # when /dev/hugepages doesn't exist.

Cache the datatype in its serialized (H5Tencode'd) form instead. - daos_vol.c: stop falsely advertising H5VL_CAP_FLAG_EXTERNAL_LINKS and H5VL_CAP_FLAG_UD_LINKS - H5_daos_link_create() hard-errors on H5VL_LINK_CREATE_UD (how H5Lcreate_external() is implemented internally by HDF5), so external/UD links were never actually supported despite the advertised flags. - daos_vol_link.c: reject H5Lcreate_hard() across two different files, matching the existing check already present in the H5Lmove/H5Lcopy path; broaden the creation-order-untracked fallback in H5_daos_link_ibco_task() so H5Ovisit's internal per-group link enumeration (non-recursive, but still needing "best effort" name-order fallback like H5Lvisit) doesn't hard-error when visiting a group without creation-order tracking (e.g. a file's root group). - daos_vol_obj.c: handle H5I_ATTR in the H5VL_OBJECT_BY_SELF target-object resolution used by H5Oget_info and H5Ovisit, instead of type-punning the attribute's H5_daos_item_t header as a full H5_daos_obj_t. HDF5 2.0 (tracked by the develop branch) API compatibility: - daos_vol_private.h: add H5_VERSION_GE-gated macros for H5Tdecode (H5Tdecode1(buf) vs H5Tdecode2(buf, buf_size)) and for looking up this connector's own registered ID by class value (H5VLpeek_connector_id_by_value(), removed in 2.0, vs H5VLget_connector_id_by_value()).

Two switch statements in daos_vol_type.c enumerate all known H5T_class_t values and error out via "invalid type class" on anything unrecognized: - H5_daos_detect_vl_vlstr_ref(): decides whether a type needs H5Tconvert() (always true for VLEN/REFERENCE, never for plain numeric leaf types like INTEGER/FLOAT). - H5_daos_need_bkg(): decides whether a background buffer is needed for conversion, same shape. Add H5T_COMPLEX to the "no conversion / no background buffer needed" group alongside INTEGER/FLOAT, since it's a fixed-size numeric leaf type from the connector's perspective - HDF5 core does all class-specific interpretation (encoding, conversion) transparently via H5Tencode/ H5Tdecode, which this connector already uses everywhere it stores a datatype, so no other connector code needed to change.
