Fix kernel history verification (#1218)
Only rewind kernels to avoid requiring proper bitmap extraction. Also avoids maintaining bitmap data for kernels by introducing a "prunable" flag on PMMR backend.

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

Replace rm_log with leaf_set (compact bitmap) (#1147)
* only store leaves in rm_log

* cleanup

* commit

* add failing test to cover case where we compact
an already compacted data file

* fix the logic for pruning the data file

* rm_log only contains leaves
prunelist only contains non-leaf subtree roots

* cleanup

* commit

* bitmap impl running in parallel

* 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

2fa32d15ce Rustify core/src/core (#1122)
Small refactoring of one folder, if it makes sense I could extend the scope.
* Remove some cloning (real and just verbosity in the code)
* Naming conventions like to/into*
* Some Clippy's suggestions

I found that we don't use field init shorthand syntax, so I didn't touch this part, was it discussed before?

* rework pool to store pool entries
with associated timer and source etc.

* all_transactions

* extra_txs so we can validate stempool against existing txpool

to next relay

* aggregate and fluff stempool is we have no relay

* refactor coinbase maturity

* rewrote basic tx pool tests to use a real txhashset via chain adapter

* rework dandelion monitor to reflect recent discussion
works locally but needs a cleanup

* refactor dandelion_monitor - split out phases

* more pool test coverage

* remove old test code from pool (still wip)

* block_building and block_reconciliation tests
