in go-flags/ini_private.go in function readIni there is no mechanism for
adding inline comments. Only comments that have a semicolon as the first
non-whitespace character are ignored.
According to Wikipedia http://en.wikipedia.org/wiki/INI_file#Comments
inline comments are not universally supported.
This change adds some white space for readability, but
name := strings.TrimSpace(line[1 : len(line)-1]) removes accidental whitespace
left in later.
Closes#135.
Also, since the new websoscket package allows the message type to be set
independently from the type of the variable, remove the casts between
strings and []byte in the websocket read/write paths. This avoids extra
copies thereby reducing the garbage generated.
Closes#134.
Rather than using bytes.NewBuffer, which is a read/write entity
(io.ReadWriter), use bytes.NewReader which is only a read entitiy
(io.Reader) in all cases where it is possible. Benchmarking shows it's
slightly faster and it's also technically more accurate since it ensures
the data is read-only.
There are a few cases where bytes.NewBuffer must still be used since a
buffer with a known length is required for those instances.
This commit resolves an issue where it was possible the block manager
could hang on shutdown due to inventory rebroadcasting. In particular, it
adds checks to prevent modification of the of rebroadcast inventory during
shutdown and adds a drain on the channel to ensure any outstanding
messages are discarded.
Found by @dajohi who also provided some of the code.
This commit updates doc.go to include the new simulation test network
magic constant as well as remove the information about BIP0037 not being
supported since that is no longer true.
This commit helps prevent transaction malleability by enforcing that the
extra dummy value on multisig transaction script contains no data for a
transaction . This syncs with a recent change in Bitcoin Core to remain
compatible.
As part of this change a new constant has been introduced which is used to
specify the script flags which are used for standard transactions. This
constant is then used in both the memory pool and the mining code to
ensure they remain in sync with one another.
Closes#131.
ok @jrick, @dajohi
This flag works similar to the existing --testnet flag does. That is to
say it selects the default simulation test network RPC port for either
btcd or btcwallet depending on whether or not the --wallet flag is also
present.
This commit, along with recent commits to btcnet and btcwire, expose a new
network that is intended to provide a private network useful for
simulation testing. To that end, it has the special property that it has
no DNS seeds and will actively ignore all addr and getaddr messages. It
will also not try to connect to any nodes other than those specified via
--connect. This allows the network to remain private to the specific
nodes involved in the testing and not simply become another public
testnet.
The network difficulty is also set extremely low like the regression test
network so blocks can be created extremely quickly without requiring a lot
of hashing power.
The default network ports are not really part of the wire protocol rather
they are part of a network parameters. Thus, this commit moves them to
the btcnet package.
The genesis blocks are not really part of the wire protocol rather they
are part of a network parameters. Thus, this commit moves the all of the
gensis blocks and tests to the btcnet package.
Also, create variables in the test package for the mainnet genesis hash,
merkle root, and coinbase transaction for use throughout the tests since
they the exported values are no longer available.
The genesis block for each network is a parameter for the network. As
such, it makes more sense to define them in this package instead of in the
wire protocol package.
ok @jrick
The examples uses a btcutil API that was recently updated from passing
btcwire.BitcoinNet to *btcnet.Params. This change updates the btcutil
call in the examples, as well as modifying the example in the README
to match that in doc.go (where errors were handled slightly
differently).
The ParamsForNet function was removed, so likewise this change removes
ErrUnknownNet error that it used to return.
As network registration is now necessary for correct handling of
alternate network encoding magics, and therefore the ErrDuplicateNet
error returned by Register is here to stay, kill the comment about the
error being removed later.
This commit refactors the code to make use of the btcnet package for
network-specific parameters instead of switching on the specific network.
For example, the percentage of the network that needs to run version 2
blocks is different between testnet and mainnet. Previously the code was
using a switch to choose these values. With this refactor, those
parameters are part of the network parameters provided when creating a new
chain instance.
Another example is checkpoints, which have been moved to btcnet so they
can be specified by the caller instead of hard coded into this package.
As a result, the checkpoints for the standard networks are now specified
in the btcnet package.
This makes it easier to add new networks such as a testnet4 should it
become needed. It also allows callers to define their own custom network
parameters without having to modify the code of the package to add new
switch cases for the custom network.
This commit adds more chain-related fields to the parameters as a part of
converting btcchain to work with btcnet parameters instead of coding the
network-specific knowledge into the package itself.
It also moves the checkpoints from btcchain since checkpoints are a
network parameter and make more sense here.
ok @jrick
This commit raises the maximum allowed size for a standard signature
script to cover a 15-of-15 multi-signature pay-to-script-hash with
compressed pubkeys.
This mirrors a recent change to remain compatible with Bitcoin Core.
ok @owinga who also helped verify and correct the script math.
Closes#128.
This change modifies the params struct to embed a *btcnet.Params,
removing the old parameter fields that are handled by the btcnet
package.
Hardcoded network checks have also been removed in favor of modifying
behavior based on the current active net's parameters.
Not all library packages, notable btcutil and btcchain, have been
updated to use btcnet yet, but with this change, each package can be
updated one at a time since the active net's btcnet.Params are
available at each callsite.
ok @davecgh
This change adds two parameters to the Params struct which are used by
btcd to alter behavior based on the active network, rather than
hardcoding checks for a particular network.
The first, ResetMinDifficulty, specifies whether the target difficulty
can change between the retarget intervals.
The second, RelayNonStdTxs, specifies whether standard transaction
checks should not be performed when accepting mempool transactions.
The zero values (false) for both of these bools are the correct
parameter values for mainnet.
While here, rename the test network version 3 to "testnet3", as both
btcd and btcwallet will include additional handling to rename this to
"testnet" for directory names, and a switch to "testnet3" is planned
in the future.
