Unlike fetch, we return DER_CSUM on update (turned into EIO by dfs) without any retry. We should retry a few times in case it is a transient error.

The patch also prints more information about the actual checksum mismatch.

Before requesting gatekeeper:

  • Two review approvals and any prior change requests have been resolved.
  • Testing is complete and all tests passed or there is a reason documented in the PR why it should be force landed and forced-landing tag is set.
  • Features: (or Test-tag*) commit pragma was used or there is a reason documented that there are no appropriate tags for this PR.
  • Commit messages follows the guidelines outlined here.
  • Any tests skipped by the ticket being addressed have been run and passed in the PR.

Gatekeeper:

  • You are the appropriate gatekeeper to be landing the patch.
  • The PR has 2 reviews by people familiar with the code, including appropriate owners.
  • Githooks were used. If not, request that user install them and check copyright dates.
  • Checkpatch issues are resolved. Pay particular attention to ones that will show up on future PRs.
  • All builds have passed. Check non-required builds for any new compiler warnings.
  • Sufficient testing is done. Check feature pragmas and test tags and that tests skipped for the ticket are run and now pass with the changes.
  • If applicable, the PR has addressed any potential version compatibility issues.
  • Check the target branch. If it is master branch, should the PR go to a feature branch? If it is a release branch, does it have merge approval in the JIRA ticket.
  • Extra checks if forced landing is requested
    • Review comments are sufficiently resolved, particularly by prior reviewers that requested changes.
    • No new NLT or valgrind warnings. Check the classic view.
    • Quick-build or Quick-functional is not used.
  • Fix the commit message upon landing. Check the standard here. Edit it to create a single commit. If necessary, ask submitter for a new summary.

* DAOS-16445 client: Add function to cycle OIDs non-sequentially (#14999)

We've noticed that with sequential order, object placement is poor.

We get 40% fill for 8GiB files with 25 ranks and 16 targets per rank
with EC_2P1G8. With this patch, we get a much better distribution.

This patch adds the following:

1. A function for cycling oid.hi incrementing by a large prime
2. For DFS, randomize the starting value
3. Modify DFS to cycle OIDs using the new function.

* DAOS-15863 container: fix a race for container cache

while destroying a container, cont_child_destroy_one() releases
its own refcount before waiting, if another ULT releases its
refcount, which is the last one, wakes up the waiting ULT and frees
it ds_cont_child straightaway, because no one else has refcount.

When the waiting ULT is waken up, it will try to change the already
freed ds_cont_child.

This patch changes the LRU eviction logic and fixes this race.

* DAOS-16446 test: HDF5-VOL test - Set object class and container prope… (#15004)

In HDF5, DFS, MPIIO, or POSIX, object class and container properties are defined
during the container create. If it’s DFS, object class is also set to the IOR
parameter. However, in HDF5-VOL, object class and container properties are
defined with the following environment variables of mpirun.

HDF5_DAOS_OBJ_CLASS (Object class)
HDF5_DAOS_FILE_PROP (Container properties)

The infrastructure to set these variables are already there in run_ior_with_pool().
In file_count_test_base.py, pass in the env vars to run_ior_with_pool(env=env) as a
dictionary. Object class is the oclass variable. Container properties can be
obtained from container -> properties field in the test yaml.

This fix is discussed in PR #14964.

For EC object update via CPD RPC, when calculate the bitmap to skip
some iods for current EC data shard, we may input NULL for "*skips"
parameter. It may cause the old logic in obj_get_iods_offs_by_oid()
to generate some undefined DRAM for "skips" bitmap. Such bitmap may
be over-written by others, as to subsequent obj_bulk_transfer() may
be misguided.

The patch also fixes a bug inside obj_bulk_transfer() that cast any
input RPC as UPDATE/FETCH by force.

The memmove read 4288 bytes from offset 4288, whereas the buffer only
had 8569 - 4288 = 4281 bytes from offset 4288. This patch fixes the
problem by adding the min(...) expression.
