5922b67 Add assertion and cast before sending reject code (Wladimir J. van der Laan)
a651403 Add absurdly high fee message to validation state (for RPC propagation) (Shaul Kfir)
This gets rid of a warning. Add an assertion to make sure that the
reject code is in the correct range for the network protocol
(if it is outside the range it must be a bug)
7b79cbd limit total length of user agent comments (Pavol Rusnak)
557f8ea implement uacomment config parameter which can add comments to user agent as per BIP-0014 (Pavol Rusnak)
Previously various user-facing strings have used inconsistent currency units "BTC",
"btc" and "bitcoins". This adds a single constant and uses it for each reference to
the currency unit.
Also adds a description of the unit for --maxtxfee, and adds the missing "amount"
field description to the (deprecated) move RPC command.
Fixes#2007
This checks to see if the system clock appears to be bad and gives a
helpful error message. If the user's clock is set incorrectly, hopefully
they'll abort, fix it, and then save themselves a fruitless resync.

c38c49d Fix argument parsing oddity with -noX (Wladimir J. van der Laan)
This avoids that premature return in the condition that a new chain is initialized
results in NULL pointer errors due to recentReject not being constructed.
Also add assertions where it is used.
Introduce a PlatformStyle to handle platform-specific customization of
the UI.
This replaces 'scicon', as well as #ifdefs to determine whether to place
icons on buttons.
The selected PlatformStyle defaults to the platform that the application
was compiled on, but can be overridden from the command line with
`-uiplatform=<x>`.
Also fixes the warning from #6328.
Clean up the code in chainparams a bit more after the recent
refactorings. In particular, make sure the structure of the "RegTest"
params matches the structure of the other classes. This makes the code
clearer to read.
Also remove redundant values of the genesis block in always-specified
optional arguments and mark variable/argument as "const".

Nodes can have divergent policies on which transactions they will accept
and relay. This can cause you to repeatedly request and reject the same
tx after its inved to you from various peers which have accepted it.
Here we add rolling bloom filter to keep track of such rejections,
clearing the filter every time the chain tip changes.
Credit goes to Alex Morcos, who created the patch that this code is
based on.
Original code by Peter Todd. Refactored to not construct the
filter at startup time by Pieter Wuille.
While CBloomFilter is usually used with an explicitly set nTweak,
CRollingBloomFilter is only used internally. Requiring every caller to
set nTweak is error-prone and redundant; better to have the class handle
that for you with a high-quality randomness source.
Additionally when clearing the filter it makes sense to change nTweak as
well to recover from a bad setting, e.g. due to insufficient randomness
at initialization, so the clear() method is replaced by a reset() method
that sets a new, random, nTweak value.
As suggested by Greg Maxwell-- unit test to make sure a block
with a double-spend in it doesn't pass validation if half of
the double-spend is already in the memory pool (so full-blown
transaction validation is skipped) when the block is received.
`bitcoind -X -noX` ends up, unintuitively, with `X` set.
(for all boolean options X)
This result is due to the odd two-pass processing of arguments. This
patch fixes this oddity and simplifies the code at the same time.
Accept strings containing decimal values, in addition to bare values.
Useful from JSON-RPC implementations where it's not possible to have
direct control over the text of numbers (e.g. where numbers are always
doubles), and it's still desired to send an exact value.
This would allow users to post JSON content with numbers encoded like
`{"value": "0.00000001"}` instead of `{"value": 0.00000001}` which some
php/python encoders wrap into 1e-8, or worse.

Handle the case where no chain tip is available, in InvalidChainFound(). This fixes a null pointer deference when running unit tests, if the genesis block or block validation code is broken.
This indicates that, eg, we have a public key for a key which may
be used as a pay-to-pubkey-hash. It generally means that we can
create a valid scriptSig except for missing private key(s) with
which to create signatures.
Since unspendable outputs can't be spent, there is no threshold at which it would be uneconomic to spend them.
This primarily targets transaction outputs with `OP_RETURN`.

Changes:
- cherry-picked on top of bitcoin:master
- added RPC test for fundrawtransaction
JSON makes no distinction between numbers and reals, and our code
doesn't need to do so either.
This removes VREAL, as well as its specific post-processing in
`UniValue::write`. Non-monetary amounts do not need to be forcibly
formatted with 8 decimals, so the extra roundtrip was unnecessary
(and potentially loses precision).
This is the format that was always returned to JSON clients.
The difference was not noticed before, because VREAL values
are post-processed by univalue.
By implementing the functionality directly it breaks the dependency
of rpcserver on utilmoneystr. FormatMoney is now only used for debugging
purposes.
To test, port over the formatting tests from util_tests.cpp to
rpc_tests.cpp.
QT_NO_KEYWORDS prevents Qt from defining the `foreach`, `signals`,
`slots` and `emit` macros.
Avoid overlap between Qt macros and boost - for example #undef hackiness
in #6421.
When no `-rpcpassword` is specified, use a special 'cookie' file for
authentication. This file is generated with random content when the
daemon starts, and deleted when it exits. Read access to this file
controls who can access through RPC. By default this file is stored in
the data directory but it be overriden with `-rpccookiefile`.
This is similar to Tor CookieAuthentication: see
https://www.torproject.org/docs/tor-manual.html.en
Alternative to #6258. Like that pull, this allows running bitcoind
without any manual configuration. However, daemons should ideally never write to
their configuration files, so I prefer this solution.
Add a function `ParseFixedPoint` that parses numbers according
to the JSON number specification and returns a 64-bit integer.
Then this in `AmountFromValue`, rather than `ParseMoney`.
Also add lots of tests (thanks to @jonasschnelli for some of them).
Fixes issue #6297.
I've never liked the chain-specific exception to having to set a
password. It gives issues with #6388 which makes it valid to
set no password in every case (as it enables random cookie authentication).
This pull removes the flag, so that all chains are regarded the same.
It also removes the username==password test, which doesn't provide any
substantial extra security.
Prevents stomping on debug logs in datadirs that are locked by other
instances and lost parameter interaction messages that can get wiped by
ShrinkDebugFile().
The log is now opened explicitly and all emitted messages are buffered
until this open occurs. The version message and log cut have also been
moved to the earliest possible sensible location.
Four cases included:
* The CLTV operand type mismatches the tx locktime. In the script it is
1 (interpreted as block height), but in the tx is 500000000
(interpreted as date)
* The stack is empty when executing OP_CLTV
* The tx is final by having only one input with MAX_INT sequence number
* The operand for CLTV is negative (after OP_0 OP_1 OP_SUB)
No longer relevant after #5957. This hack existed because of another
hack where the numthreads parameter, on regtest, doubled as how many
blocks to generate.
CTransAction::IsEquivalentTo was introduced in #5881.
This functionality is only useful to the wallet, and should never have
been added to the primitive transaction type.
72b9452 When processing RPC commands during warmup phase, parse the request object before returning an error so that id value can be used in the response. (Forrest Voight)
request object before returning an error so that id value can
be used in the response.
Prior to this commit, RPC commands sent during Bitcoin's
warmup/startup phase were responded to with a JSON-RPC error
with an id of null, which violated the JSON-RPC 2.0 spec:
id: This member is REQUIRED. It MUST be the same as the value
of the id member in the Request Object. If there was an error
in detecting the id in the Request object (e.g. Parse
error/Invalid Request), it MUST be Null.
To determine the default for `-par`, the number of script verification
threads, use [boost:🧵:physical_concurrency()](http://www.boost.org/doc/libs/1_58_0/doc/html/thread/thread_management.html#thread.thread_management.thread.physical_concurrency)
which counts only physical cores, not virtual cores.
Virtual cores are roughly a set of cached registers to avoid context
switches while threading, they cannot actually perform work, so spawning
a verification thread for them could even reduce efficiency and will put
undue load on the system.
Should fix issue #6358, as well as some other reported system overload
issues, especially on Intel processors.
The function was only introduced in boost 1.56, so provide a utility
function `GetNumCores` to fall back for older Boost versions.

New, undocumented-on-purpose -mocktime=timestamp command-line
argument to startup with mocktime set. Needed because
time-related blockchain sanity checks are done on startup, before a
test has a chance to make a setmocktime RPC call.
And changed the setmocktime RPC call so calling it will not result in
currently connected peers being disconnected due to inactivity timeouts.
Transactions that fail CLTV verification will be rejected from the
mempool, making it easy to test the feature. However blocks containing
"invalid" CLTV-using transactions will still be accepted; this is *not*
the soft-fork required to actually enable CLTV for production use.
<nLockTime> CHECKLOCKTIMEVERIFY -> <nLockTime>
Fails if tx.nLockTime < nLockTime, allowing the funds in a txout to be
locked until some block height or block time in the future is reached.
Only the logic and unittests are implemented; this commit does not have
any actual soft-fork logic in it.
Thanks to Pieter Wuille for rebase.
Credit goes to Gregory Maxwell for the suggestion of comparing the
argument against the transaction nLockTime rather than the current
time/blockheight directly.
