This commit modifies the logging to also log all output to a rolling log
file in the btcd home directory under the logs folder. It uses a maximum
size of 10MB per log file and a max rotation size of 3. This means the
log files will not exceed 30 megabytes.
The code was previously only changing the logging level if it wasn't the
default which is accurate for setting the log level once at startup time,
but it needs to set it unconditionally to allow dynamic updates.
Also, make every subsystem within btcd use its own logger instance so each
subsystem can have its own level specified independent of the others.
This is work towards #48.
- Remove periods from --rpccert/--rpckey since none of the other options use
them
- Make it a little more clear that the --listen and --rpclisten options can be
used multiple times by changing the summary to start with "Add an ..."
which also matches the --addpeer style
All rpc sockets now listen using TLS by default, and this can not be
turned off. The keys (defauling to the datadirectory) may be provided by
--rpccert and --rpckey. If the keys do not exist we will generate a new
self-signed keypair with some sane defaults (hostname and all current
interface addresses).
Additionally add tls capability to btcctl so that it can still be used.
The certificate to use for verify can be provided on the commandline or
verification can be turned off (this leaves you susceptible to MITM
attacks)
Initial code from dhill (rpc tls support) and jrick (key generation),
cleanup, debugging and polishing from me.
The regression test mode is special and therefore most likely will not
want to use the same settings that are in the configuration file. The -C
option can still be used to specify a config file in regression test mode
if desired.
This commit makes use of the new default-mask go-flags option in
conjunction with delaying the usage display until after the config file is
parsed. This has a couple of nice properties such as showing the actual
values that will be used as loaded from the specific config file instead
of the defaults specified in btcd itself, and also allows any config file
parsing errors to be shown prior to displaying the usage.
This allows the provision of address/port pairs to be listened on instead
of just providing the port. e.g.:
btcd --listen 1.2.3.4:4321 --listen 127.0.0.01 --listen [::1]:5432
When --proxy and --connect are used, we disable listening *unless* any --listen
arguments have been provided, when we will listen on those addresses as
requested.
Initial code by davec, integration by myself.

This commit makes use of the new btcutil.AppDataDir function which chooses
appropriate data directories for each supported operating system. It also
adds code to the upgrade path to properly migrate existing data from the
old to new locations.
This is part of work toward issue #30.
This commit provides a new --cpuprofile flag that can be used to specify a
file path to write CPU profile data into. The resulting profile can then be
consumed by the 'go tool pprof' command.
This commit provides a new flag, --nocheckpoints, to disable built-in
checkpoints.
Checkpoints are used for a number of things such a ensuring
the block chain being downloaded matches various known good blocks,
allowing quicker verification on old blocks since scripts don't have to be
executed, and preventing forks from old blocks, etc.
This commit adds environment variable expansion and path cleaning to the
data directory. This allows the user to specify data paths in the config
file such as datadir=~/.btcd/data and datadir=$SOMEVAR/btcd. It also
adds usage instructions and an example to the sample btcd.conf file.
This commit modifies the way the data paths are handled. Since there will
ultimately be more data associated with each network than just the block
database, the data path has been modified to be "namespaced" based on the
network. This allows all data associated with a specific network to
simply use the data path without having to worry about conflicts with data
from other networks.
In addition, this commit renames the block database to "blocks" plus a
suffix which denotes the database type. This prevents issues that would
otherwise arise if the user decides to use a different database type and
a file/folder with the same name already eixsts but is of the old database
type. For most users this won't matter, but it does provide nice
properties for testing and development as well since it makes it easy to
go back and forth between database types.
This commit also includes code to upgrade the old database paths to the
new ones so the change is seamless for the user.
Finally, bump the version to 0.2.0.
This change paves the way for saving more than just the block database to
the filesystem (such as address manager data, index data, etc) where the
name "dbdir" no longer makes sense.
When running in regression test mode, it is unlikely the user wants to
connect to permanent peers they have configured in their config file.
This commit modifies the code to ignore the config file entry when in
regression test mode. The user can still provide -a (or --addpeer) on the
command line to override this if they really want to connect out to a
specific peer during regression test mode.
Although not required if the proxy set is indeed Tor, setting this option
does the following:
- Sends DNS queries over the Tor network (during dns seed lookup). This
stops your IP from being leaked via DNS.
- Does not disable the listening port. This allows the hidden services
feature of Tor to be used.
