d189770080 Wallet LMDB backend (#1151)
* Migrate main node store to LMDB

In preparation to using LMDB as a wallet database, migrate the
node db. There's no point in having 2 key-value stores.
In addition LMDB provides a few advantages as a node db, namely a
much faster build (compared to RocksDb), lesser dependencies and
transactions.

* Migrated p2p store to lmdb, stuff compiles

* More fixes, chain tests starting to pass

* Fixed txhashset rollback messing with block save and general batch delimitation. Chain tests passing.

* rustfmt

* LMDB max map size of 10MB isn't really workable. Half TB seems reasonable.

* Fix wallet tests

* Rather crucial commit was missing

* rustfmt

* Fixing new merged tests following lmdb changes

* rustfmt

* * Make txhashset validation read-only on fast sync to avoid having
a really long open transaction.
* Fix deadlock in new block processing, batch should always be
created within a txhashset lock (when they interact).

* Comment about batch and txhashset interlacing

* Fix store tests to use batch

* Externalize wallet config and seed

* Converted direct read access to file outputs map to an iterator

* Cleaned up and simplified wallet Backend trait:

* No more direct mutable access to internal structures (HashMap)
* Batch interface for all writes
* Remove unneeded read wrapper (read_wallet)

* rustfmt

* First (incomplete) pass at wallet LMDB backend

* Progressing on lmdb backent iml

* Added batch impl for LMDB wallet backend. Pretty much done with it, but not sure how to deal with commit (owned).

* rustfmt

* Wrapping LMDB batch around a refcell to work around borrow rules

* Compilation up to grin chain

Kernel sum and MMR sizes in block header (#1163)
* Add kernel commitments sum and kernel and output MMR sizes to block header
* Sum a block without including previous sums, cleanup. Blocks are now summed and validated based on their own totals and not the totals since genesis. This allows to get rid of BlockSum and simplified the setting of a new block's roots, kernel sum and MMR sizes. Fixes #116
* Additional kernel MMR validation to check all prior header roots successively
* Wallet tests fix

* only store leaves in rm_log

an already compacted data file

* fix the logic for pruning the data file

* rm_log only contains leaves

* rustfmt

* this is better - rewind unremoves outpu pos spent by rewound inputs

* commit

* commit

* pass bitmap around when rewinding

* store and retrieve input bitmap per block from the db

* Replace the RemoveLog with the UTXO set.

* utxo set starting to pass tests

* stuff works...

* split store types out
added some tests to compare the performance of the rm_log and the proposed utxo_set

* pull prune_list out into standalone file

* cleanup, get rid of unused height param

* cleanup and add doc comments

* add support for migrating rm_log to utxo_set

* take snapshot of utxo file during fast sync
implement migration of rm_log -> utxo_set

* rename rewound_copy to snapshot

* fixup pmmr tests to reflect cutoff_pos

* cleanup unused import

* check_compact needs to rewind the utxo_set as appropriate

* fix pool tests

* fixup core tests

* cache block_input_bitmaps via LruCache in store

* cache block header on initial write to db

* rename utxo_set -> leaf_set
and remove references to "spent" in grin_store

* better document the rewind behavior

Cleanup positional indexes for rewind, introducing block markers (#759)

respective positions in the output and kernel MMRs. This is now sufficient

[WIP] Abridged sync (#440)
* Util to zip and unzip directories
* First pass at sumtree request/response. Add message types, implement the exchange in the protocol, zip up the sumtree directory and stream the file over, with necessary adapter hooks.
* Implement the sumtree archive receive logicGets the sumtree archive data stream from the network and write it to a file. Unzip the file, place it at the right spot and reconstruct the sumtree data structure, rewinding where to the right spot.
* Sumtree hash structure validation
* Simplify sumtree backend buffering logic. The backend for a sumtree has to implement some in-memory buffering logic to provide a commit/rollback interface. The backend itself is an aggregate of 3 underlying storages (an append only file, a remove log and a skip list). The buffering was previously implemented both by the backend and some of the underlying storages. Now pushing back all buffering logic to the storages to keep the backend simpler.
* Add kernel append only store file to sumtrees. The chain sumtrees structure now also saves all kernels to a dedicated file. As that storage is implemented by the append only file wrapper, it's also rewind-aware.
* Full state validation. Checks that:
    - MMRs are sane (hash and sum each node)
    - Tree roots match the corresponding header
    - Kernel signatures are valid
    - Sum of all kernel excesses equals the sum of UTXO commitments
minus the supply
* Fast sync handoff to body sync. Once the fast-sync state is fully setup, get bacj in body sync
mode to get the full bodies of the last blocks we're missing.
* First fully working fast sync
* Facility in p2p conn to deal with attachments (raw binary after message).
* Re-introduced sumtree send and receive message handling using the above.
* Fixed test and finished updating all required db state after sumtree validation.
* Massaged a little bit the pipeline orphan check to still work after the new sumtrees have been setup.
* Various cleanup. Consolidated fast sync and full sync into a single function as they're very similar. Proper conditions to trigger a sumtree request and some checks on receiving it.

hash (features|commitment) in output mmr (#615)

* playing around with lock_height as part of the switch commitment hash

* cleanup

* include features in the switch commit hash key

* commit

* rebase off master

* commit

* cleanup

* missing docs

* rework coinbase maturity test to build valid tx

* pool and chain tests passing (inputs have switch commitments)

* commit

* cleanup

* check inputs spending coinbase outputs have valid lock_heights

* wip - got it building (tests still failing)

* use zero key for non coinbase switch commit hash

* fees and height wrong order...

* send output lock_height over to wallet via api

* no more header by height index
workaround this for wallet refresh and wallet restore

* refresh heights for unspent wallet outputs where missing

* TODO - might be slow?

* simplify - do not pass around lock_height for non coinbase outputs

* commit

* fix tests after merge

* build input vs coinbase_input
switch commit hash key encodes lock_height
cleanup output by commit index (currently broken...)

* is_unspent and get_unspent cleanup - we have no outputs, only switch_commit_hashes

* separate concept of utxo vs output in the api
utxos come from the sumtrees (and only the sumtrees, limited info)
outputs come from blocks (and we need to look them up via block height)

* cleanup

* better api support for block outputs with range proofs

* basic wallet operations appear to work
restore is not working fully
refresh refreshes heights correctly (at least appears to)

* wallet refresh and wallet restore appear to be working now

* fix core tests

* fix some mine_simple_chain tests

* fixup chain tests

* rework so pool tests pass

* wallet restore now safely habndles duplicate commitments (reused wallet keys)
for coinbase outputs where lock_height is _very_ important

* wip

* validate_coinbase_maturity
got things building
tests are failing

* lite vs full versions of is_unspent

* builds and working locally
zero-conf - what to do here?

* handle zero-conf edge case (use latest block)

* introduce OutputIdentifier, avoid leaking SumCommit everywhere

* fix the bad merge

* pool verifies coinbase maturity via is_matured
this uses sumtree in a consistent way

* cleanup

* add docs, cleanup build warnings

* fix core tests

* fix chain tests

* fix pool tests

* cleanup debug logging that we no longer need

* make out_block optional on an input (only care about it for spending coinbase outputs)

* cleanup

* bump the build
