The weight unit is merely a consensus rule detail and is largely
irrelevant for fee-rate calculations and mempool policy rules (e.g. for
package relay and TRUC limits), so there doesn't seem to be any value of
using a granularity that we can't even guarantee to reach exactly
anyway.
Switch to the more natural unit of vsize instead, which simplifies both
the padding implementation and the current tests that take use of this
padding. The rather annoying multiplications by `WITNESS_SCALE_FACTOR`
can then be removed and weird-looking magic numbers like `4004` can be
replaced by numbers that are more connected to actual policy limit
constants from the codebase, e.g. `1001` for exceeding
`TRUC_CHILD_MAX_VSIZE` by one.
Behavior prior to this commit allows some transactions to
enter into the local mempool but not be reported to the user
when encountering a PackageValidationResult::PCKG_TX result.
This is further compounded with the fact that any transactions
submitted to the mempool during this call would also not be
relayed to peers, resulting in unexpected behavior.
Fix this by, if encountering a package error, reporting all
wtxids, along with a new error field, and broadcasting every
transaction that was found in the mempool after submission.
Note that this also changes fees and vsize to optional,
which should also remove an issue with other-wtxid cases.
Test for scenario(s) outlined in PR 28251.
Test what happens when a package transaction spends a mempool coin which
is fetched and then disappears mid-package evaluation due to eviction or
replacement.
We want to be able to re-use fill_mempool so that none of the tests
affect each other.
Change the logs from info to debug because they are otherwise repeated
many times in the test output.
Since this test was changed to use MiniWallet instead of the Bitcoin
Core wallet (see commit d447ded6ba),
the setting doesn't have any effect and hence can be removed.
By specifying the `datacarriersize` option instead of the more
generic `acceptnonstdtxn`, we can be more specific about what
part of the transaction is non-standard and can be sure that all
other aspects follow the standard policy.
The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.

The helper `send_large_txs` in its current interface has a fee_rate
parameter, implying that it would create a transaction with exactly that
rate. Unfortunately, this fee rate is only passed to MiniWallet's
`create_self_transfer` method, which can't know that we append several
tx outputs after, increasing the tx's vsize and decreasing it's fee rate
accordingly.
In our case, the fee rate is off by several orders of magnitude, as the
tx's vsize changes changes from 96 to 67552 vbytes (>700x), i.e. the
value passed to this function is neither really a fee rate nor an
absolute fee, but something in-between, which is very confusing.
Clarify the interface by passing an absolute fee that is deducted in the end
(and verified, via testmempoolaccept) and also describe how we come up with the
value passed.
Because the right-hand side of this comparison can be influenced
externally, e.g. via the -maxmempool argument, the existing mempool state,
host memory usage, etc.
aad3090 [rpc] Adding ::minRelayTxFee amount to getmempoolinfo and updating mempoolminfee help description (Jeff Rade)
Pull request description:
These are RPC document changes from #11475 which is now merged. Took into consideration comments from #11475 and #6941 for this PR.
Biggest change here is when calling `getmempoolinfo`, will now show the `minrelaytxfee` in the JSON reponse (see below):
```
$ bitcoin-cli getmempoolinfo
{
"size": 50,
"bytes": 13102,
"usage": 70480,
"maxmempool": 300000000,
"mempoolminfee": 0.00001000,
"minrelaytxfee": 0.00001000
}
```
Fixes#8953

Almost all test scripts currently need to override the __init__()
method. When they do that they need to call into super().__init__() as
the base class does some generic initialization.
This commit makes the base class __init__() call into set_test_params()
method. Individual test cases can override set_test_params() to setup
their test parameters.
