This commit adds a new function to the blockchain package named
IsCoinBaseTx which performs the same function as IsCoinBase except it
takes raw wire transactions as opposed to the higher level util
transactions.
While here, it also adds a file for benchmarks along with a couple of
benchmarks for the IsCoinBase and IsCoinBaseTx functions.
Finally, the function was very slightly optimized:
BenchmarkIsCoinBaseOld 100000000 10.7 ns/op 0 B/op 0 allocs/op
BenchmarkIsCoinBaseNew 200000000 6.05 ns/op 0 B/op 0 allocs/op
For every transaction in a newly accepted block, process the orphan
pool moving now no longer orphan transactions to the mempool.
Previously, no longer orphan transactions would remain in the orphan
pool.
This change increases the maximum allowed bytes allowed in pushed
data to be considered a nulldata transaction. This matches the current
value the reference implementation uses by default.
This commit provides a new function named PkScriptLocs on the MsgTx type
which can be used to efficiently retrieve a list of offsets for the public
key scripts for the serialized form of the transaction.
This is useful for certain applications which store fully serialized
transactions and want to be able to quickly index into the serialized
transaction to extract a give public key script directly thereby avoiding
the need to deserialize the entire transaction.
This commit modifies finalized transaction check used by the memory pool
and block templates to use the network adjusted time instead of the
unadjusted local time. This helps keep the transactions accepted to the
memory pool, and hence allowed to relay, more consistent across nodes.
When the fields in the command for the getnetworkhashps RPC don't have the
fields set, use the intended default values.
Since the btcjson package sets these fields to the default values when a
command is unmarshaled from the wire, this typically isn't necessary.
However, when the RPC server calls the handler internally with optional
command fields set to nil, as is the case in getmininginfo, the defaults
need to be set as well.
By exporting StandardVerifyFlags, clients can ensure they create
transactions that btcd will accept into its mempool.
This flag doesn't belong in txscript. It belongs in a
policy package. However, this is currently the least worse place.
This modifies the recently added code which rejects free/low-fee
transactions with insufficient priority to ignore resurrected transactions
from disconnected blocks. It also exempts resurrected transactions from
the free/low-fee rate limiting.
This commit moves the definition of the flags which are needed to check
transaction scripts higher up the call stack to pave the way for adding
support for v3 blocks. While here, also spruce up a couple of sections.
There are no functional changes in this commit.
This commit contains what is essentially a complete rewrite of the btcctl
utility to make use of the new features provided by the latest version
btcjson and improve several things along the way. The following
summarizes the changes:
- The supported commands and handling now come directly from btcjson, so
it is no longer necessary to manually add new commands. Once a command
has been registered with btcjson, it will automatically become usable by
btcctl complete with full error handling (once it is re-compiled of
course)
- Rather than dumping the entire list of commands on every error, the user
now must specifically request the list of command via the -l option
- The list of commands is now categorized by chain and wallet and
alphabetized
- The help flag now only shows the help options instead of also dumping
all of the commands
- The error display on valid commands with invalid parameters has been
greatly improved to show the specific parameter number, reason, and
error code
- When a valid command is specified with invalid parameter, only the usage
for that specific command is shown now
- It is now possible to use a SOCKS5 proxy for connection
- The output of commands has been improved in the following ways:
- Strings on commands such as getbestblockhash no longer have quotes
wrapped around them
- Fields that are integers no longer show in scientific notation when
they are large (timestamps for example)
This closes#305 as a side effect.
This commit updates the SearchRawTransactionsCmd verbose parameter in the
latest version of btcjson to an integer to match recent changes to the
previous version of btcjson.
By default, have the mempool reject free and low-fee transactions that
have insufficient priority to be mined in the next block.
Addtionally, add a new configuration option, -norelaypriority, to
disable the check.
This commit converts the RPC server over to use the new features available
in the latest version of btcjson and improve a few things along the way.
This following summarizes the changes:
- All btcjson imports have been updated to the latest package version
- The help has been significantly improved
- Invoking help with no command specified now provides an alphabetized
list of all supported commands along with one-line usage
- The help for each command is automatically generated and provides much
more explicit information such as the type of each parameter, whether
or not it's optional or required, etc
- The websocket-specific commands are now provided when accessing the
help when connected via websockets
- Help has been added for all websocket-specific commands and is only
accessible when connected via websockets
- The error returns and handling of both the standard and websocket
handlers has been made consistent
- All RPC errors have been converted to the new RPCError type
- Various variables have been renamed for consistency
- Several RPC errors have been improved
- The commands that are marked as unimplemented have been moved into the
separate map where they belong
- Several comments have been improved
- An unnecessary check has been removed from the createrawtransaction
handler
- The command parsing has been restructured a bit to pave the way for
JSON-RPC 2.0 batching support
- When invalid HTTP Basic Access Authentication details are provided to
the websocket endpoint, return a WWW-Authenticate header just like the
non-websocket endpoint
- When a connection to the websocket endpoint fails to properly upgrade,
return a 400 Bad Request HTTP error status code
This commit reorders the RPC server code to more closely match the
ordering used by the rest of the code base such that functions are
typically defined before they are used and near their call site.
The ScriptVerifyMinimalData enforces that all push operations use the
minimal data push required. This is part of BIP0062.
This commit mimics Bitcoin Core commit
698c6abb25c1fbbc7fa4ba46b60e9f17d97332ef
This changes the behavior of the rescan RPC to automatically set the
client up for transaction notifications for transactions paying to any
rescanned address and spending outputs in the final rescan UTXO set
after a rescanned is performed through the best block in the chain.
Remove ScriptCanonicalSignatures and use the new
ScriptVerifyDERSignatures flag. The ScriptVerifyDERSignatures
flag accomplishes the same functionality.
`searchrawtransactions` can return multiple transactions. Previously the documentation erroneously had return examples showing only a single tx for each case.
* The documentation previously presented the output for the `non-verbose` case as a single json string, instead of an array of json strings.
* Similarly, for the `verbose` mode, the documentation detailed the output as a single json object, instead of an array of json objects.
This commit contains the entire btcjson repository along with several
changes needed to move all of the files into the btcjson directory in
order to prepare it for merging. This does NOT update btcd or any of the
other packages to use the new location as that will be done separately.
- All import paths in the old btcjson test files have been changed to the
new location
- The coveralls badge has been removed since it unfortunately doesn't
support coverage of sub-packages
This is ongoing work toward #214.
- Also update to use the new container-based builds
- Add coveralls.io support
- Update build badge to use SVG
- Add badges for coverage, license, and godoc
- For now, set it to change to he v2 directory
- This will need to be changed once the v1 code is replaced
This commit implements a reimagining of the way the btcjson package
functions based upon how the project has evolved and lessons learned while
using it since it was first written. It therefore contains significant
changes to the API. For now, it has been implemented in a v2 subdirectory
to prevent breaking existing callers, but the ultimate goal is to update
all callers to use the new version and then to replace the old API with
the new one.
This also removes the need for the btcws completely since those commands
have been rolled in.
The following is an overview of the changes and some reasoning behind why
they were made:
- The infrastructure has been completely changed to be reflection based instead
of requiring thousands and thousands of lines of manual, and therefore error
prone, marshal/unmarshal code
- This makes it much easier to add new commands without making marshalling
mistakes since it is simply a struct definition and a call to register that
new struct (plus a trivial New<foo>Cmd function and tests, of course)
- It also makes it much easier to gain a lot of information from simply
looking at the struct definition which was previously not possible
such as the order of the parameters, which parameters are required
versus optional, and what the default values for optional parameters
are
- Each command now has usage flags associated with them that can be
queried which are intended to allow classification of the commands such
as for chain server and wallet server and websocket-only
- The help infrastructure has been completely redone to provide automatic
generation with caller provided description map and result types. This
is in contrast to the previous method of providing the help directly
which meant it would end up in the binary of anything that imported the
package
- Many of the structs have been renamed to use the terminology from the
JSON-RPC
specification:
- RawCmd/Message is now only a single struct named Request to reflect the fact
it is a JSON-RPC request
- Error is now called RPCError to reflect the fact it is specifically an RPC
error as opposed to many of the other errors that are possible
- All RPC error codes except the standard JSON-RPC 2.0 errors have been
converted from full structs to only codes since an audit of the codebase
has shown that the messages are overridden the vast majority of the time
with specifics (as they should be) and removing them also avoids the
temptation to return non-specific, and therefore not as helpful, error
messages
- There is now an Error which provides a type assertable error with
error codes so callers can better ascertain failure reasons
programatically
- The ID is no longer a part of the command and is instead specified at the time
the command is marshalled into a JSON-RPC request. This aligns better with
the way JSON-RPC functions since it is the caller who manages the ID that is
sent with any given _request_, not the package
- All <Foo>Cmd structs now treat non-pointers as required fields and pointers as
optional fields
- All New<Foo>Cmd functions now accept the exact number of parameters, with
pointers to the appropriate type for optional parameters
- This is preferrable to the old vararg syntax since it means the code will
fail to compile if the optional arguments are changed now which helps
prevent errors creep in over time from missed modifications to optional args
- All of the connection related code has been completely eliminated since this
package is not intended to used a client, rather it is intended to provide
the infrastructure needed to marshal/unmarshal Bitcoin-specific JSON-RPC
requests and replies from static types
- The btcrpcclient package provides a robust client with connection management
and higher-level types that in turn uses the primitives provided by this
package
- Even if the caller does not wish to use btcrpcclient for some reason, they
should still be responsible for connection management since they might want
to use any number of connection features which the package would not
necessarily support
- Synced a few of the commands that have added new optional fields that
have since been added to Bitcoin Core
- Includes all of the commands and notifications that were previously in
btcws
- Now provides 100% test coverage with parallel tests
- The code is completely golint and go vet clean
This has the side effect of addressing nearly everything in, and therefore
closes#26.
Also fixes#18 and closes#19.
* Decouple logging and handling of distinct error messages for cases of
failed tx look up.
* This also fixes a bug wherein the `addrindexer` failed to lookup a tx
(since it didn't exist), but continued since the returned error was
nil.
