    ceph-disk: rely on /dev/disk/by-partuuid instead of special-casing journal symlinks
    
    This was necessary when ceph-disk-udev didn't create the by-partuuid (and
    other) symlinks for us, but now it is fragile and error-prone.  (It also
    appears to be broken on a certain customer RHEL VM.)  See
    d7f7d613512fe39ec883e11d201793c75ee05db1.
    
    Instead, just use the by-partuuid symlinks that we spent all that ugly
    effort generating.

    mon: Monitor: StoreConverter: clearer debug message on 'needs_conversion()'
    
    The previous debug message outputted the function's name, as often our
    functions do.  This was however a source of bewilderment, as users would
    see those in logs and think their stores would need conversion.  Changing
    this message is trivial enough and it will make ceph users happier log
    readers.

    mon: Monitor: do not reopen MonitorDBStore during conversion
    
    We already open the store on ceph_mon.cc, before we start the conversion.
    Given we are unable to reproduce this every time a conversion is triggered,
    we are led to believe that this causes a race in leveldb that will lead
    to 'store.db/LOCK' being locked upon the open this patch removes.
    
    Regardless, reopening the db here is pointless as we already did it when
    we reach Monitor::StoreConverter::convert().

    messages/MClientReconnect: clear data when encoding
    
    The MClientReconnect puts everything in the data payload portion of
    the message and nothing in the front portion.  That means that if the
    message is resent (socket failure or something), the messenger thinks it
    hasn't been encoded yet (front empty) and reencodes, which means
    everything gets added (again) to the data portion.
    
    Decoding keep decoding until it runs out of data, so the second copy
    means we decode garbage snap realms, leading to the crash in bug
    
    Clearing data each time around resolves the problem, although it does
    mean we do the encoding work multiple times.  We could alternatively
    (or also) stick some data in the front portion of the payload
    (ignored), but that changes the wire protocol and I would rather not
    do that.

    mon: once sync full is chosen, make sure we don't change our mind
    
    It is possible for a sequence like:
    
     - probe
     - first probe reply has paxos trim that indicates a full sync is
       needed
     - start sync
     - clear store
     - something happens that makes us abort and bootstrap (e.g., the
       provider mon restarts
     - probe
     - first probe reply has older paxos trim bound and we call an election
     - on election completion, we crash because we have no data.
    
    Non-determinism of the probe decision aside, we need to ensure that
    the info we share during probe (fc, lc) is accurate, and that once we
    clear the store we know we *must* do a full sync.

    The PaxosServiceMessage version field is meant for client-coordinated

    mon: be smarter about calculating last_epoch_clean lower bound
    
    We need to take PGs whose mapping has not changed in a long time into
    account.  For them, the pg state will indicate it was clean at the time of
    the report, in which case we can use that as a lower-bound on their actual
    latest epoch clean.  If they are not currently clean (at report time), use
    the last_epoch_clean value.

    osd: report pg stats to mon at least every N (=500) epochs
    
    The mon needs a moderately accurate last_epoch_clean value in order to trim
    old osdmaps.  To prevent a PG that hasn't peered or received IO in forever
    from preventing this, send pg stats at some minimum frequency.  This will
    increase the pg stat report workload for the mon over an idle pool, but
    should be no worse that a cluster that is getting actual IO and sees these
    updates from normal stat updates.
    
    This makes the reported update a bit more aggressive/useful in that the epoch
    is the last map epoch processed by this PG and not just one that is >= the
    currenting interval.  Note that the semantics of this field are pretty useless
    at this point.

    osd: limit number of inc osdmaps send to peers, clients
    
    We should not send an unbounded number of inc maps to our peers or clients.
    In particular, if a peer is not contacted for a while, we may think they
    have a very old map (say, 10000 epochs ago) and send thousands of inc maps
    when the distribution shifts and we need to peer.
    
    Note that if we do not send enough maps, the peers will make do by
    requesting the map from somewhere else (currently the mon).  Regardless
    of the source, however, we must limit the amount that we speculatively
    share as it usually is not needed.

    mon: fix osdmap stash, trim to retain complete history of full maps
    
    The current interaction between sync and stashing full osdmaps only on
    active mons means that a sync can result in an incomplete osdmap_full
    history:
    
     - mon.c starts a full sync
     - during sync, active osdmap service should_stash_full() is true and
       includes a full in the txn
     - mon.c sync finishes
     - mon.c update_from_paxos gets "latest" stashed that it got from the
       paxos txn
     - mon.c does *not* walk to previous inc maps to complete it's collection
       of full maps.
    
    To fix this, we disable the periodic/random stash of full maps by the
    osdmap service.
    
    This introduces a new problem: we must have at least one full map (the first
    one) in order for a mon that just synced to build it's full collection.
    Extend the encode_trim() process to allow the osdmap service to include
    the oldest full map with the trim txn.  This is more complex than just
    writing the full maps in the txn, but cheaper--we only write the full
    map at trim time.
    
    This *might* be related to previous bugs where the full osdmap was
    missing, or case where leveldb keys seemed to 'disappear'.

    client: remove O_LAZY
    
    The once-upon-a-time unique O_LAZY value I chose forever ago is now
    O_NOATIME, which means that some clients are choosing relaxed
    consistency without meaning to.
    
    It is highly unlikely that a real O_LAZY will ever exist, and we can
    select it in the ceph case with the ioctl or libcephfs call, so drop
    any support for doing this via open(2) flags.
    
    Update doc/lazy_posix.txt file re: lazy io.

    mon: remove bad assert about monmap version
    
    It is possible to start a sync when our newest monmap is 0.  Usually we see
    e0 from probe, but that isn't always published as part of the very first
    paxos transaction due to the way PaxosService::_active generates it's
    first initial commit.
    
    In any case, having e0 here is harmless.

    mon/Paxos: fix sync restart
    
    If we have a sync going, and an election intervenes, the client will
    try to continue by sending a new start_chunks request.  In order to
    ensure that we get all of the paxos commits from our original starting
    point (and thus properly update the keys from which they started),
    only pay attention if they *also* send their current last_committed
    version.  Otherwise, start them at the beginning.

    mon: include any new paxos commits in each sync CHUNK message
    
    We already take note of the paxos version when we begin the sync.  As
    sync progresses and there are new paxos commits/txns, include those
    and update last_committed, so that when sync completes we will have
    a full view of everything that happened during sync.
    
    Note that this does not introduce any compatibility change.  This change
    *only* affects the provider.  The key difference is that at the end
    of the sync, the provide will set version to the latest version, and
    not the version from the start of the sync (as was done previously).

    mds: warn on unconnected snap realms
    
    When there are more than one active MDS, restarting MDS triggers
    assertion "reconnected_snaprealms.empty()" quite often. If there
    is no snapshot in the FS, the items left in reconnected_snaprealms
    should be other MDS' mdsdir. I think it's harmless.
    
    If there are snapshots in the FS, the assertion probably can catch
    real bugs. But at present, snapshot feature is broken, fixing it is
    non-trivial. So replace the assertion with a warning.

    mon/PGMonitor: use post_paxos_update, not init, to refresh from osdmap
    
    We do two things here:
     - make init an one-time unconditional init method, which is what the
       health service expects/needs.
     - switch PGMonitor::init to be post_paxos_update() which is called after
       the other services update, which is what PGMonitor really needs.
    
    This is a new version of the fix originally in commit
    a2fe0137946541e7b3b537698e1865fbce974ca6 (and those around it).  That is,
    this re-fixes a problem where osds do not see pg creates from their
    subscribe due to map_pg_creates() not getting called.

    The create_initial() method may get called multiple times; make sure it
    will unconditionally generate new/initial rotating keys.  Move the block
    up so that we can easily assert as much.

    common/pick_addresses: behave even after internal_safe_to_start_threads
    
    ceph-mon recently started using Preforker to working around forking issues.
    As a result, internal_safe_to_start_threads got set sooner and calls to
    pick_addresses() which try to set string config values now fail because
    there are no config observers for them.
    
    Work around this by observing the change while we adjust the value.  We
    assume pick_addresses() callers are smart enough to realize that their
    result will be reflected by cct->_conf and not magically handled elsewhere.

    mon/PaxosService: allow paxos service writes while paxos is updating
    
    In commit f985de28f86675e974ac7842a49922a35fe24c6c I mistakenly made
    is_writeable() false while paxos was updating due to a misread of
    Paxos::propose_new_value() (I didn't see that it would queue).
    This is problematic because it narrows the window during which each service
    is writeable for no reason.
    
    Allow service to be writeable both when paxos is active and updating.

    Treat this as an extension of the recovery process, e.g.
    
     RECOVERING -> ACTIVE
    or
     RECOVERING -> UPDATING_PREVIOUS -> ACTIVE
    
    and we are not active until we get to "the end" in both cases.

    mon/Paxos: not readable when LOCKED
    
    If we are re-proposing a previously accepted value from a previous quorum,
    we should not consider it readable, because it is possible it was exposed
    to clients as committed (2/3 accepted) but not recored to be committed, and
    we do not want to expose old state as readable when new state was
    previously readable.

    mon/Paxos: go active *after* refreshing
    
    The update_from_paxos() methods occasionally like to trigger new activity.
    As long as they check is_readable() and is_writeable(), they will defer
    until we go active and that activity will happen in the normal callbacks.
    
    This fixes the problem where we active but is_writeable() is still false,
    triggered by PGMonitor::check_osd_map().

    Do the paxos refresh inside finish_proposal, ordered *after* the leader

    does not kill us.
    
    Also, remove unnecessary finish_queued_proposal() and move the logic inline
    where the bad leader assertion is obvious.
