- only pause mining once we've got the lock (in practice, it'll
already be paused by another thread if we can't get the lock
at once though)
- do not call prepare_handle_incoming_blocks when we dismissed
all the blocks, it only causes cleanup_handle_incoming_blocks
to complain afterwards
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.

In particular, the prepare_handle_incoming_blocks call
is pretty lengthy, and entirely pointless in the common
case where several different connections will prepare
the exact same blocks.
- fix wrong block being used when a new block is received between
a node elaying a fluffy block and sending a new fluffy block
with txes a peer did not have
- misc a neverending ping pong requesting the same missing txids
when a new block is received in the meantime, causing the top
block to not be the one we need
- send the original fluffy block message block height when sending
a new fluffy block, not the current top height, which might
have been updated since
- avoid sending back the whole block blob when asking for txes,
send only the hash instead
- plus misc cleanup and additional debugging logs
When exiting while the miner is running, finding a block after
the p2p layer has been shutdown will cause a crash as the now
uninitialized p2p layer is asked to relay the found block to
any peers.
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.
source, and CPU has been idle for some time, then begin mining to some
threshold (don't destroy the users' CPU).
This patch only supports windows and linux (I've only tested on Win64 and
Ubuntu).
The variables currently default to pretty conservative values (i.e. 20%
CPU mining threshold).
Zero change is sent to a random address, which confuses the code
which determines which key to use to encrypt the payment id.
Ignore zero amounts for this purpose, so the payment id gets
encrypted with the real destination's key.

If a rct transaction can be made with just one input, a second
output will be added. This output will be the smallest amount
output available. However, if this output is a non rct output
with less available fake outs than requested, the transaction
will be rejected. We now check the histogram to only consider
outputs with enough available fake outs in the first place.
poolstate.bin and p2pstate.bin are stored in .bitmonero/ if the default
P2P port is being used.
If another port is used both files are stored in
.bitmonero/PORTNUMBER/.
Easily fixed by moving a C++ header out of 'extern "C" {...}'.

This would have tried to send a second output to make the tx
look like the 2/2 ideal, but it would not fail to find one
because picking an output from preferred_inputs priority list
did not remove it from the unused tranfer/dust outputs, so
it would try to send the same output twice.
While there, I also added a check to avoid sending a second
input if it's related to the first. Better 1/2 than linking
inputs, I think.
A random peer from the gray peer list is selected and a connection is
made to check if the peer is alive.
If the connection and handshake are successful the peer is promoted to
the white peer list, in case of failure the peer is evicted from the
gray peer list.
The connection is closed after the check in either case.
This avoids indirectly leaking the real output to the daemon,
and is faster.
This will still happen for more complex cases, especially
when cancelling a tx and "re-rolling" it.
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.

If a checksum word is present, language detection would use
just the word prefixes. However, a set of word prefixes may
be found in more than one language, and so the wrong language
may be found first, which could then fail the checksum, since
the check may be done with a different unique prefix length
from the one it was created from.
We now make a checksum test when we we detect a language from
prefixes only, to make sure we have the correct one.
fsync the DB asynchronously, to allow block download/verification
to proceed while syncing. Sync after every batch. Note that
"fastest" still defaults to fastest:async:1000.
If we'd make a rct tx with just one input, we try to add
a second one to match the 2/2 ideal. This means more txes
use that template (and are thus using a larger anonymity
set), and it coalesces outputs "for free". We use the
smallest amount outputs in priority for this, so we can
"clean" the wallet at the same time.
