These are unlikely to happen at random, but Wijaya et al made
a paper about it, so people might try it on purpose now (and it
turns out it's easy to add anyway)
This will avoid careless forkers polluting the shared database
even if they make their own chain. They'll then automatically
start using another subdb, and any key-reusing fork of those
forks will reuse their subdbs.
It scans for known spent outputs and stores their public keys
in a database which can then be read by the wallet, which can
then avoid using those as fake outs in new transactions.
Usage: monero-blockchain-blackball db1 db2...
This uses the shared database in ~/.shared-ringdb

178014c9 split off readline code into epee_readline (moneromooo-monero)

437421ce wallet: move some scoped_message_writer calls from the libs (moneromooo-monero)
e89994e9 wallet: rejig to avoid prompting in wallet2 (moneromooo-monero)
ec5135e5 move input_line from command_line to simplewallet (moneromooo-monero)

default install targets
Binaries available to download on https://getmonero.org/downloads/ as
embedding monerod, monero-wallet-{cli,rpc} and
monero-blockchain-{ex,im}port.
This change synchronise download results with a manual build from
source
And optimize import startup:
Remember start_height position during initial count_blocks pass
to avoid having to reread entire file again to arrive at start_height
4e0e4e99 blockchain_import: warn for chunks over 500000, not 100000 (moneromooo-monero)
5b29e87f blockchain_import: properly cleanup core/db on exit (moneromooo-monero)
e167c4d9 blockchain_import: do not error out on truncated files (moneromooo-monero)
Hide DB types from db_types.h - no reason to recompile dependencies
when DB types change.
Also remove lingering in-memory DB references, they've been
obsolete since 9e82b694da

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.
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.
TEST:
blockchain_export -h
This should show "berkeley" as an available option to --database.
With an existing BerkeleyDB database, run:
blockchain_export --database berkeley
Pass the CMake bit width setting to compile flags for blockchain_import
and blockchain_converter.
For LMDB on 32-bit, hyc has found that batch size of 100 appears to be a
good default.
These modes match those optionally provided as part of the daemon's
--db-type argument.
Argument after the # is interpreted as a composite mode if there's only
one (no comma separated arguments).
Sample usage:
blockchain_import --database lmdb#fastest
blockchain_import --database berkeley#fastest
Multiple specific DB flags are still supported, e.g.
blockchain_import --database lmdb#nosync,nordahead
blockchain_import --database berkeley#txn_nosync
