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.
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 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.
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.

Ordinarily, getwork will return an error if btcd is not connected to any
other peers. This commit relaxes that requirement when running in
regression test mode since it is useful for development purposes.
While here, also improve check which returns an error from getwork is not
current to exclude the check when the best chain height is zero since the
code never believes it is current when at height 0.
Along the same lines as the previous commit, the RPCs that return
serialized data structures should use the max protocol version btcd
supports as opposed to the maximum protocol version etcwire supports.
The getinfo RPC should return the max protocol version btcd supports as
opposed to the maximum protocol version btcwire supports. Currently they
are both the same value, so there is no issue. However, they will not
always be the same.
This commit updates the block manager's local chain state when a block
processed by submitting it directly to the block manager as opposed to
only when it comes from the network.
Also, it modifies the submitblock RPC to use the concurrent safe block
manager process block instead of the unsafe btcchain version.
The combination of these two fixes ensure the internal block manager chain
state is properly synced with the actual btcchain state regardless of how
blocks are added.
This change fixes rescan to include transactions that pay to the
pubkey for a rescanned pubkey hash address. This behavior was lost
when the rescan was optimized for specific types of the
btcutil.Address interface.

This commit correctly sets the error in the marhsalled reply if it is
already a *btcjson.Error. Previously it would only set the error if it
was not of that type which led to some RPC results showing no error when
they actually had one.
In Discover, the reponse was lowercased for comparison. However,
this caused a 404 - Not found when fetching the url provided by
the location header if the url contained uppercase.
ok @owainga
In practise the races caused by not protecting these quite simply didn't
matter, they couldn't actually cause any damage whatsoever. However, I
am sick of hearing about these essentially false positivies whenever
someone runs the race detector (yes, i know that race detector has no
false positives but this was effectively harmess).
verified to shut the detector up by dhill.
If we switch the knuth shuffle to the version that swaps the element
with an element between it and the end of the array, then once we have
gotten to the amount of elements we need they won't change later in the
algorithm. Terminating here means that we only do 23% of the length of
the array worth of random swaps at most.
We make ka.na immutable in the address manager. Whenever we would update
the structure we replace it with a new copy. This beats making a copy of
all addresses once per getaddr command (max is just over 23000 we would
be copying, compared to at most 2000 copies on a new getaddr that has
all addresses we know with newer dates).
On unknown inventory types, handleGetDataMsg would loop forever.
After fixing that, if a getdata request only had unknown inventory
types, it would block forever.
ok @davecgh
Copying the RIPEMD160 after SHA256 hash result into a new stack array
to be used as a map lookup key can be quite expensive, and this should
be avoided if possible on intensive tasks such as rescans. This
change takes advantage of the new Hash160 methods of the
AddressPubKeyHash and AddressScriptHash types to use the address's
underlying hash array directly, rather than creating a copy from the
ScriptAddress result.
Unfortunately, for AddressPubKey, ScriptAddress may return either a
byte slice of len 33 or 65 depending on whether the pubkey is
compressed or not, so no such straightforward optimization is
possible.
As a result of this change, I have seen rescans perform roughly 3.5x
faster than before.
The websocket extension command to register for notifications when a new
transaction has been accepted to the memory pool and the resulting
notifications have been renamed. This commit catches up to the change.
