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.
* Address index is built up concurrently with the `--addrindex` flag.
* Entire index can be deleted with `--dropaddrindex`.
* New RPC call: `searchrawtransaction`
* Returns all transacitons related to a particular address
* Includes mempool transactions
* Requires `--addrindex` to be activated and fully caught up.
* New `blockLogger` struct has been added to factor our common logging
code
* Wiki and docs updated with new features.
* When an inv is to be sent to the server for relaying, the sender
already has access to the underlying data. So
instead of requiring the relay to look up the data by
hash, the data is now coupled in the request message.
This was previously hard-coded to zero instead of using the offset
provided by the median time source which takes time samples from the other
connected nodes.
This commit modifies the getblocktemplate RPC to correctly handle the
curtime field.
Currently, the RPC server will refuse to serve a block template if the
current time is before the minimum allowed time for a block even though
the real generated block template already accounted for it.
This consists of three changes:
- Remove the unnecessary and incorrect check in the RPC invocation for the
current time against the min required time since it is already handled
properly by the block template generation.
- Expose the network time source to the RPC work state and use the
adjusted time for checking against the maximum allowed time instead of
the current time.
- Set the returned RPC result curtime field to the time of the generated
block header.
Fixes#209.
This commit modifies the creation of RPC results to ignore errors in
script disassembly since they already contain the error string inline and
the RPC results must still be generated regardless.
This was already done in the decodescript RPC, however the same thing was
not being done in the higher level verbose transaction results. This
applies to both the createrawtransaction and decoderawtransaction RPCs.
Also, since this was the only thing that could error within those
functions, the error returns and caller checking of now non-existent
errors have been removed.
Fixes#210.
This commit introduces a new flag, --notls, which can be used to disable
TLS for the RPC server. However, the flag can only be used when the RPC
server is bound to localhost interfaces. This is intended to prevent the
situation where someone decides they want to expose the RPC server to the
web for remote management/access, but forgot they have TLS disabled.
This commit corrects the error check from the createTxRawResult call in
handleGetRawTransaction. It was previously given a different name which
resulted in the wrong error being checked.
Fixes#196.
This prevents a downgrade attack to the vulnerable SSLv3. While here,
go ahead and require at least TLS 1.2 since TLS 1.0 and 1.1 have their
own set of issues and it's only a matter of time before those would
need to be completely avoided as well.

This commit addresses a few nitpicks in the recent getrawmppol update
which populates the starting and current priority fields.
In particular:
- Move the new calcInputValueAge function before the function which
invokes it so it is consistent with the rest of the mempool code
- Double space after periods for consistency
- Correct the comments for calcInputValueAge to indiciate that inputs
which are in the the memory pool count as zero toward the value age
rather than the incorrect claim that that the overal input value age is
zero when one of them does
- Rename endingPriority to currentPriority to match the RPC field and its
actual function
- Make the comment about using zero when input transactions can't be found
for some reason more accurate since there can be (and frequently is)
more than one input transaction
This commit uses the new MedianTimeSource API in btcchain to create a
median time source which is stored in the server and is fed time samples
from all remote nodes that are connected. It also modifies all call sites
which now require the the time source to pass it in.
This change modifies the behavior of the gettxout RPC to match the
behavior of the reference client. If a transaction output is spent by
a mined transaction, the handler will now return nil (JSON null).
While here, avoid indexing some slices multiple times, by creating a
local variable instead.
This commit implements reject handling as defined by BIP0061 and bumps the
maximum supported protocol version to 70002 accordingly.
As a part of supporting this a new error type named RuleError has been
introduced which encapsulates and underlying error which could be one of
the existing TxRuleError or btcchain.RuleError types.
This allows a single high level type assertion to be used to determine if
the block or transaction was rejected due to a rule error or due to an
unexpected error. Meanwhile, an appropriate reject error can be created
from the error by pulling the underlying error out and using it.
Also, a check for minimum protocol version of 209 has been added.
Closes#133.
This commit implements a portion of the mutations section of BIP0023.
In particular, it adds the mutable, mintime, maxtime, and noncerange keys
to the returned block template along with indicating support for the time,
transactions/add, prevblock, and coinbase/append mutations. Also, the
addition of the mintime and maxtime fields imply support for the
time/decrement and time/increment mutations. Further, if the caller
indicates the coinbasevalue capability, the coinbasetxn field will be
omitted thereby implying support for the coinbase and generation
mutations.
Closes#124.
This commit implements the long polling portion of the getblocktemplate
RPC as defined by BIP0022. Per the specification, each block template is
returned with a longpollid which can be used in a subsequent
getblocktemplate request to keep the connection open until the server
determines the block template associated with the longpollid should be
replaced with a new one.
This is work towards #124.
This commit implements the non-optional and template tweaking support for
the getblocktemplate RPC as defined by BIP0022. This implementation does
not yet include long polling support.
This is work towards #124.
