qa/suites/upgrade: disable min pg per osd warning
disable the TOO_FEW_PGS warning, as 1ac34a5ea3d1aca299b02e574b295dd4bf6167f4 is not backported to mimic, we
will have TOO_FEW_PGS warnings when a healthy cluster is expected when
upgrading from mimic.
this change disables this warning by setting "mon_pg_warn_min_per_osd" to
"0".
this change is not cherry-picked from master. as 1ac34a5ea3d1aca299b02e574b295dd4bf6167f4 is already included by master,
and we don't perform upgrade from mimic on master branch.
qa/tasks: do not cancel pending pg num changes on mimic
mimic does not support auto split/merge, but we do test mimic-x on
nautilus, which ends up with failures like:
ceback (most recent call last):
File "/home/teuthworker/src/git.ceph.com_git_teuthology_py2/teuthology/contextutil.py", line 34, in nested
yield vars

if pool['pg_num'] != pool['pg_num_target']:
KeyError: 'pg_num_target'
so we need to skip this if 'pg_num_target' is not in pg_pool_t::dump().
this change is not cherry-picked from master, as we don't test
mimic-x on master.
Also, mon_pg_warn_min_per_osd is disabled by default now (or set to a
low value in vstart/testing) so there's no need to base the pg count on
this value.
Ideally someday we can remove this so that the default cluster value is
used but we need to keep this for deployments of older versions of Ceph.

client: reset requested_max_size if file write is not wanted
write can stuck at waiting for larger max_size in following sequence of

- client opens a file and writes to position 'A' (larger than unit of

- client closes the file handle and updates wanted caps (not wanting

- client opens and truncates the file, writes to position 'A' again.
At the 1st event, client set inode's requested_max_size to 'A'. At the
2nd event, mds removes client's writable range, but client does not reset

The unmap action only sends a signal to the kernel to notify the

unmap followed by an immediate re-map to the same device might
fail since the unmap is still in-progress.

rgw: reshard: skip stale bucket id entries from reshard queue
If we encounter a reshard queue entry that has an older ID compared to the
bucket's current ID, it'd mean that some other process or a manual reshard has
already processed this entry, skip processing the entry this time. An
alternative is to verify the num_shards that we have in queue >= the current
shards, but this would mean that we may reshard a recently manual resharded
bucket again which might not be intended

mgr: force purge normal ceph entities from service map
Normal ceph services can send task status updates to manager.
Task status is tracked in service map implying that normal
ceph services have entries in service map and daemon tracking
index (daemon state). But the manager prunes entries from daemon
state when it receives an updated map (fs, mon, etc...). This
causes periodic pruning of service map entries to fail for normal
ceph services (those which send task status updates) since it
expects a corresponding entry in daemon state.

FileNotFoundError exception, so the exception is populated to ceph-mgr

mgr/PyModule: fix missing tracebacks in handle_pyerror()
In certain cases, errors raised in mgr modules don't actually result in a
proper traceback in the mgr log; all you see is a message like "'Hello'
object has no a ttribute 'dneasdfasdf'", but you have no idea where that
came from, which is a complete PITA to debug.
Here's what's going on: handle_pyerror() calls PyErr_Fetch() to get
information about the error that occurred, then passes that information
back to python's traceback.format_exception() function to get the traceback.
If we write code in an mgr module that explicitly raises an exception
(e.g.: 'raise RuntimeError("that didn't work")'), the error value returned
by PyErr_Fetch() is of type RuntimeError, and traceback.format_exception()
does the right thing. If however we accidentally write code that's just
broken (e.g.: 'self.dneasdfasdf += 1'), the error value returned is not
an actual exception, it's just a string. So traceback.format_exception()
freaks out with something like "'str' object has no attribute '__cause__'"
(which we don't actually ever see in the logs), which in turn dumps us in a
"catch (error_already_set const &)" block, which just prints out the
single line error string.
https://docs.python.org/3/c-api/exceptions.html#c.PyErr_NormalizeException
tells us that "Under certain circumstances, the values returned by
PyErr_Fetch() below can be “unnormalized”, meaning that *exc is a class
object but *val is not an instance of the same class.". And that's exactly
the problem we're having here. We're getting a 'str', not an Exception.
Adding a call to PyErr_NormalizeException() turns the value back into a
proper Exception type and traceback.format_exception() now always does the
right thing.
I've also added calls to peek_pyerror() in the catch blocks, so if anything
else ever somehow causes traceback.format_exception to fail, we'll at least
have an idea of what it is in the log.
