14 months agoLeader should always apply modifications as local 76/82576/24
Tomas Cere [Tue, 18 Jun 2019 12:54:56 +0000 (14:54 +0200)]
Leader should always apply modifications as local

Normally an entry application is as follows:
1. leader sends an append entry off to persistence and replicates it to
2. leaders creates its ClientRequestTracker
3. when the entry is done with persistence and replication leader moves its
   commit index
4. part of moving the commit index is sending an ApplyState message which
   finalizes the entry application in the DataTree
5. The ApplyState determines if a ClientRequestTracker is present and adds
   an identifier to the ApplyState message if it is. This determines the way
   in which the finalize of the entry application happens in the DataTree.
   If it is present the entry is applied as if it originated on the leader,
   if it is not present it is applied as if the node is a follower.

The problem is when the leader flaps in a leader -> follower -> leader
transition after 2. and before 4..

This would mean that the new leader no longer has the ClientRequestTracker
which was created in the previous leader state, which means that when it
starts with 5. it will create the ApplyState without an identifier
and the entry finishes up the application as if the node is a follower.

This means that it will be applied without finishCommit which means that
the transaction will be forever stuck in COMMIT_PENDING state until
the node would be restarted.

Change this up, so that the leader will apply modifications as local, even
when it looses its ClientRequestTracker and add Identifiable to payloads
which require it.

Since this code path should never occur when we are candidate, catch this
transition. As ClientRequestTracker becomes an optional entity, we hide that
as well.

a few of stateful encoding rules.

Where Lithium did encoding did not perform any look-behind except
for LeafSetEntryNodes and only maintained simple coding tables,
this coder maintains simple 'parent' state tracking.

While the state tracking is not mandated on the encoder side, some
amount of tracking is required in the decoder side to provide full
coverage of coding constructs.

Two examples of this are:
- parent QName references, which are expanded to cover not only
  LeafSet/LeafSetEntry, but also UnkeyedList/UnkeyedListEntry
  and most importantly Map/MapEntry pairs
- Map/MapEntry tracking is also important for coding leaf nodes
  which represent keys -- in those cases emitting the leaf value
  is superfluous, as it can be looked up from MapEntry's predicates

Add Magnesium encoding tokens

Changes to how uint8/16/32/64 types are mapped results in the need
to transfer the new value types. These represent 4 brand new tokens,
which need to be handled.

One option would be to fork NeonSR2 and modify it, somehow dealing
with value lookups (i.e. Uint8 is not valid in SR2 stream, but tokens
are shared across Lithium/NeonSR).

Another option is to create a streaming format from scratch, coming
up with a completely new family of tokens and encoding rules. This
is attractive, as both current formats have three deficiencies:

1) they encode MapEntry key values twice, once in the leaf itself
   and once in the entry's NodeIdentifierWithPredicates
2) they are '0-happy', i.e. they do not recognize that integer codes
   and sizes are typically much smaller than the 4-byte range and thus
   much of the stream is just small ints encoded as 4 bytes
3) while they are simple and straighforward, they also end up wasting
   bits -- the four token families (codes, value types, node types,
   path argument types) each have at most 15 distinct values, and
   hence the bytes used to transmit them have 4 empty bits (or more)

Hence we take the other option and design a streaming format with
brand new tokens, which are structured to carry as much more
information per byte.

This is done by combining 'type' information with forward coding
hints, for example:

- a Boolean leaf value would previously require 2 bytes:
    (byte)    ValueTypes.BOOL_TYPE
    (byte)    true/falseIn the new tokens
  whereas new tokens express this in one byte:
    (byte)    LeafValue.BOOLEAN_{FALSE,TRUE}
- a byte[5] value would require 10 bytes to encode:
    (byte)    ValueTypes.BINARY_TYPE
    (int)     length
    (5 bytes) bytes
  whereas new tokens express this in 6 bytes:
    (byte)    ValueTypes.BINARY_0 + 5 (works up to 127)
    (5 bytes) bytes

A similar approach is taken when encoding NormalizedNode types. Here
we recognize there are only 14 node types (currently) and hence we
can provide up to 4 additional bits for information about how the
node's identifier is encoded.

For PathArguments, we also use separate coding, where the format
is flexible based on the 4 types on identifiers there are, each
having slightly different format. Most notable here is the integration
of QName reference coding (for normal PathArguments) and integrated
set size coding (for AugmentationIdentifiers).

This this patch adds just the token definitions, along with basic
documentation and version declaration.
