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.
Closes#33
allow listens to fail, but warn. error if all failed
fmt
So far we only do level 0 and level 1 checks (precense and basic
sanity). The checks done at higher levels in bitcoind are closely
coupled with their database layout.
arguably Closes#13
This change allows wallet to record all transactions in a block before
receving the new block notification, and then process them all
together when the blockconnected notification arrives.
Previously, RemoveMinedTxRequest was being run from a caller which
held a reader lock for the websocket request contexts. When
RemoveMinedTxRequest tried to grab a writer lock, it would block.
This change creates a new function, removeMinedTxRequest, that does
not grab any locks, and the caller (NotifyBlockConnected) grabs a
writer lock instead of a reader lock.
Previously, on a blockconnected notification, the websocket context
reader lock was not always being given up properly. This change
defers the unlock so it will always happen.
This fixes an issue where wallet will stop responding (due to not
being able to complete its handshake) on reconnect.
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 modifies the tests to setup a chain instance backed by the new
memory database backend for btcdb. This allows the tests to avoid
creating and cleaning up files and also allows the tests to run faster
since it can all happen in memory.
The chainSetup function has also been changed to provide logic to switch
on the database type to allow for easy changing of the backend to a
different database type as needed. For example, it could be useful to
provide extra testing against new database backends.
This commit adds a new backend driver which conforms to the btcdb
interface to provide a memory only database. This is primarily useful for
testing purposes as normal operations require a persistent block storage
mechanism.
Rather than defining CheckBlockSanity as a member of a BlockChain
instance, define it at the root level so it is truly context free as
intended. In order to make it context free, the proof of work limit is
now a required parameter.
This change reworks where the command parsing occurs to be done before
handlers are checked. Before, the websocket extension handler called
the standard handler with the same message, and if it was unhandled,
would unmarshal it a second time for checking extension handlers.
This commit adds tests to ensure the new "fast" paths in readElement and
writeElement work properly including proper fallback to the slower
reflection based read/write of the binary package.
This commit modifies the writeElement function to have a "fast path" which uses type
assertions for all of the types which btcwire write so the more expensive
reflection-based binary.Write can be avoided.
Also, this changes all cases that were writing raw ShaHash (32-byte) arrays (which
requires a stack copy) instead simply passing the pointer.
The following benchmark results show the results for serializing a block header
after these changes:
Before: BenchmarkWriteBlockHeader 500000 5566 ns/op
After: BenchmarkWriteBlockHeader 1000000 991 ns/op
This is part of the ongoing effort to optimize serialization as noted in
conformal/btcd#27.
