blockchain_db: do not throw on expected partial results getting keys
When scanning for outputs used in a set of incoming blocks,
we expect that some of the inputs in their transactions will
not be found in the blockchain, as they could be in previous
blocks in that set. Those outputs will be scanned there at
a later point. In this case, we add a flag to control wehther
an output not being found is expected or not.

db_lmdb: fix bad height saved in tx data
The recent change to not keep separate track of the blockchain
height caused the reported height to jump early in the lmdb
transaction (when the block data is added to the blocks table),
rather than at the end, after everything succeeded. Since the
block data is added before the transaction data, this caused
the transaction data to be saved with a height one more than
its expected value.

Fix this by saving the block data last. This should have no
side effects.

Change logging to easylogging++
This replaces the epee and data_loggers logging systems with
a single one, and also adds filename:line and explicit severity
levels. Categories may be defined, and logging severity set
by category (or set of categories). epee style 0-4 log level
maps to a sensible severity configuration. Log files now also
rotate when reaching 100 MB.

To select which logs to output, use the MONERO_LOGS environment
variable, with a comma separated list of categories (globs are
supported), with their requested severity level after a colon.
If a log matches more than one such setting, the last one in
the configuration string applies. A few examples:

This one is (mostly) silent, only outputting fatal errors:

MONERO_LOGS=*:FATAL

This one is very verbose:

MONERO_LOGS=*:TRACE

This one is totally silent (logwise):

MONERO_LOGS=""

This one outputs all errors and warnings, except for the
"verify" category, which prints just fatal errors (the verify
category is used for logs about incoming transactions and
blocks, and it is expected that some/many will fail to verify,
hence we don't want the spam):

MONERO_LOGS=*:WARNING,verify:FATAL

Log levels are, in decreasing order of priority:
FATAL, ERROR, WARNING, INFO, DEBUG, TRACE

Subcategories may be added using prefixes and globs. This
example will output net.p2p logs at the TRACE level, but all
other net* logs only at INFO:

MONERO_LOGS=*:ERROR,net*:INFO,net.p2p:TRACE

Logs which are intended for the user (which Monero was using
a lot through epee, but really isn't a nice way to go things)
should use the "global" category. There are a few helper macros
for using this category, eg: MGINFO("this shows up by default")
or MGINFO_RED("this is red"), to try to keep a similar look
and feel for now.

Existing epee log macros still exist, and map to the new log
levels, but since they're used as a "user facing" UI element
as much as a logging system, they often don't map well to log
severities (ie, a log level 0 log may be an error, or may be
something we want the user to see, such as an important info).
In those cases, I tried to use the new macros. In other cases,
I left the existing macros in. When modifying logs, it is
probably best to switch to the new macros with explicit levels.

The --log-level options and set_log commands now also accept
category settings, in addition to the epee style log levels.

db_lmdb: guard against going out of sync on unexpected db results
m_num_outputs keeps track of the number of outputs, which should
be the same as the size of both the output_txs and output_amounts
databases. If one goes out of sync, we need to throw to abort
whatever it is we were doing.

wallet: select part of the fake outs from recent outputs
25% of the outputs are selected from the last 5 days (if possible),
in order to avoid the common case of sending recently received
outputs again. 25% and 5 days are subject to review later, since
it's just a wallet level change.

e1c7af35d4 cmake: transitive deps and remove deprecated LINK_*
Keep the immediate direct deps at the library that depends on them,
declare deps as PUBLIC so that targets that link against that library
get the library's deps as transitive deps.

Break dep cycle between blockchain_db <-> crytonote_core.
No code refactoring, just hide cycle from cmake so that
it doesn't complain (cycles are allowed only between
static libs, not shared libs).

This is in preparation for supproting BUILD_SHARED_LIBS cmake
built-in option for building internal libs as shared.

core: faster find_blockchain_supplement
Since this queries block heights for blocks that may or may not
exist, queries for non existing blocks would throw an exception,
and that would slow down the loop a lot. 7 seconds to go through
a 30 hash list.

Fix this by adding an optional return block height to block_exists
and using this instead. Actual errors will still throw an
exception.

This also cuts down on log exception spam.

db_lmdb: fix reorg with "halfway rct" coinbase outputs 2016-08-29 22:44:17 +01:00
moneromooo-monero
c3b3260ae5
New "Halfway RingCT" outputs for coinbase transactions
When RingCT is enabled, outputs from coinbase transactions
are created as a single output, and stored as RingCT output,
with a fake mask. Their amount is not hidden on the blockchain
itself, but they are then able to be used as fake inputs in
a RingCT ring. Since the output amounts are hidden, their
"dustiness" is not an obstacle anymore to mixing, and this
makes the coinbase transactions a lot smaller, as well as
helping the TXO set to grow more slowly.

Also add a new "Null" type of rct signature, which decreases
the size required when no signatures are to be stored, as
in a coinbase tx.

move the rct commitments to the output_amounts database
Since these are needed at the same time as the output pubkeys,
this is a whole lot faster, and takes less space. Only outputs
of 0 amount store the commitment. When reading other outputs,
a fake commitment is regenerated on the fly. This avoids having
to rewrite the database to add space for fake commitments for
existing outputs.

This code relies on two things:

- LMDB must support fixed size records per key, rather than
per database (ie, all records on key 0 are the same size, all
records for non 0 keys are same size, but records from key 0
and non 0 keys do have different sizes).

- the commitment must be directly after the rest of the data
in outkey and output_data_t.
