The Append / truncate operations were racy. When a datafile reaches 2Gb, a new file is needed. For this operation, we require a writelock, which is not needed in the 99.99% of all cases where the data does fit in the current head-file.
This transition from readlock to writelock was incorrect, and as the readlock was released, a truncate operation could slip in between, and truncate the data. This would have been fine, however, the Append operation continued writing as if no truncation had occurred, e.g writing item 5 where item 0 should reside.
This PR changes the behaviour, so that if when we run into the situation that a new file is needed, it aborts, and retries, this time with a writelock.
The outcome of the situation described above, running on this PR, would instead be that the Append operation exits with a failure.
This PR introduces:
- db.put to put a value into the database
- db.get to read a value from the database
- db.delete to delete a value from the database
- db.stats to check compaction info from the database
- db.compact to trigger a db compaction
It also moves inspectdb to db.inspect.
This PR implements the following modifications
- Don't shortcut check if block is present, thus avoid disk lookup
- Don't check hash ancestry in early-check (it's still done in parallel checker)
- Don't check time.Now for every single header
Charts and background info can be found here: https://github.com/holiman/headerimport/blob/main/README.md
With these changes, writing 1M headers goes down to from 80s to 62s.
This commit splits the eth package, separating the handling of eth and snap protocols. It also includes the capability to run snap sync (https://github.com/ethereum/devp2p/blob/master/caps/snap.md) , but does not enable it by default.

This PR implements unclean shutdown marker. Every time geth boots, it adds a timestamp to a list of timestamps in the database. This list is capped at 10. At a clean shutdown, the timestamp is removed again.
Thus, when geth exits unclean, the marker remains, and at boot up we show the most recent unclean shutdowns to the user, which makes it easier to diagnose root-causes to certain problems.

This PR significantly changes the APIs for instantiating Ethereum nodes in
a Go program. The new APIs are not backwards-compatible, but we feel that
this is made up for by the much simpler way of registering services on
node.Node. You can find more information and rationale in the design
document: https://gist.github.com/renaynay/5bec2de19fde66f4d04c535fd24f0775.
There is also a new feature in Node's Go API: it is now possible to
register arbitrary handlers on the user-facing HTTP server. In geth, this
facility is used to enable GraphQL.
There is a single minor change relevant for geth users in this PR: The
GraphQL API is no longer available separately from the JSON-RPC HTTP
server. If you want GraphQL, you need to enable it using the
./geth --http --graphql flag combination.
The --graphql.port and --graphql.addr flags are no longer available.
This change introduces garbage collection for the light client. Historical
chain data is deleted periodically. If you want to disable the GC, use
the --light.nopruning flag.
The ancients variable in the freezer is a list of hashes, which
identifies all of the hashes to be frozen. The slice is being allocated
with a capacity of `limit`, which is the number of the last block
this batch will attempt to add to the freezer. That means we are
allocating memory for all of the blocks in the freezer, not just
the ones to be added.
If instead we allocate `limit - f.frozen`, we will only allocate
enough space for the blocks we're about to add to the freezer. On
mainnet this reduces usage by about 320 MB.

* core/rawdb: Stop freezer process as part of freezer.Close()
When you call db.Close(), it was closing the leveldb database first,
then closing the freezer, but never stopping the freezer process.
This could cause the freezer to attempt to write to leveldb after
leveldb had been closed, leading to a crash with a non-zero exit code.
This change adds a quit channel to the freezer, and freezer.Close()
will not return until the freezer process has stopped.
Additionally, when you call freezerdb.Close(), it will close the
AncientStore before closing leveldb, to ensure that the freezer goroutine
will be stopped before leveldb is closed.

This PR fixes issues in TableDatabase.
TableDatabase is a wrapper of underlying ethdb.Database with an additional prefix.
The prefix is applied to all entries it maintains. However when we try to retrieve entries
from it we don't handle the key properly. In theory the prefix should be truncated and
only user key is returned. But we don't do it in some cases, e.g. the iterator and batch
replayer created from it. So this PR is the fix to these issues.

Transaction hashes now store a reference to their corresponding
block number as opposed to their hash. In benchmarks this was
shown to reduce storage by over 12 GB.
The main limitation of this approach is that transactions on
non-canonical blocks could never be looked up, however that is
currently not supported.
The database version has been upgraded to version 5 and the
transaction lookup process is backwards-compatible with the
prior two transaction lookup formats prexisting in the
database instance. Tests have been added to ensure this.
* core/rawdb: tiny review nit fixes
This PR is a more advanced form of the dirty-to-clean cacher (#18995),
where we reuse previous database write batches as datasets to uncache,
saving a dirty-trie-iteration and a dirty-trie-rlp-reencoding per block.
