4757c04 [config] Remove blockmaxsize option (John Newbery)
Pull request description:
The blockmaxsize option was marked as deprecated in V0.15.1, and code
was added to convert provided blockmaxsize into blockmaxweight. However,
this code was incorrectly implemented, and blockmaxsize was silently
ignored.
No users have complained about blockmaxsize being ignored, so just
remove it in V0.17.
Fixes #12640

How to Upgrade
|
|
==============
|
|
|
|
If you are running an older version, shut it down. Wait until it has completely
|
|
shut down (which might take a few minutes for older versions), then run the
|
|
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
|
|
or `bitcoind`/`bitcoin-qt` (on Linux).
|
|
|
|
The first time you run version 0.15.0, your chainstate database will be converted to a
|
|
new format, which will take anywhere from a few minutes to half an hour,
|
|
depending on the speed of your machine.
|
|
|
|
Note that the block database format also changed in version 0.8.0 and there is no
|
|
automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading
|
|
directly from 0.7.x and earlier without redownloading the blockchain is not supported.
|
|
However, as usual, old wallet versions are still supported.
|
|
|
|
Downgrading warning
|
|
-------------------
|
|
|
|
The chainstate database for this release is not compatible with previous
|
|
releases, so if you run 0.15 and then decide to switch back to any
|
|
older version, you will need to run the old release with the `-reindex-chainstate`
|
|
option to rebuild the chainstate data structures in the old format.
|
|
|
|
If your node has pruning enabled, this will entail re-downloading and
|
|
processing the entire blockchain.
|
|
|
|
Compatibility
|
|
==============
|
|
|
|
Bitcoin Core is extensively tested on multiple operating systems using
|
|
the Linux kernel, macOS 10.8+, and Windows 7 and newer (Windows XP is not supported).
|
|
|
|
Bitcoin Core should also work on most other Unix-like systems but is not
|
|
frequently tested on them.
|
|
|
|
Notable changes
|
|
===============
|
|
|
|
RPC changes
|
|
------------
|
|
|
|
### Low-level changes
|
|
|
|
- The `createrawtransaction` RPC will now accept an array or dictionary (kept for compatibility) for the `outputs` parameter. This means the order of transaction outputs can be specified by the client.
|
|
- The `fundrawtransaction` RPC will reject the previously deprecated `reserveChangeKey` option.
|
|
- Wallet `getnewaddress` and `addmultisigaddress` RPC `account` named
|
|
parameters have been renamed to `label` with no change in behavior.
|
|
- Wallet `getlabeladdress`, `getreceivedbylabel`, `listreceivedbylabel`, and
|
|
`setlabel` RPCs have been added to replace `getaccountaddress`,
|
|
`getreceivedbyaccount`, `listreceivedbyaccount`, and `setaccount` RPCs,
|
|
which are now deprecated. There is no change in behavior between the
|
|
new RPCs and deprecated RPCs.
|
|
- Wallet `listreceivedbylabel`, `listreceivedbyaccount` and `listunspent` RPCs
|
|
add `label` fields to returned JSON objects that previously only had
|
|
`account` fields.
|
|
- `sendmany` now shuffles outputs to improve privacy, so any previously expected behavior with regards to output ordering can no longer be relied upon.
|
|
|
|
External wallet files
|
|
---------------------
|
|
|
|
The `-wallet=<path>` option now accepts full paths instead of requiring wallets
|
|
to be located in the -walletdir directory.
|
|
|
|
Newly created wallet format
|
|
---------------------------
|
|
|
|
If `-wallet=<path>` is specified with a path that does not exist, it will now
|
|
create a wallet directory at the specified location (containing a wallet.dat
|
|
data file, a db.log file, and database/log.?????????? files) instead of just
|
|
creating a data file at the path and storing log files in the parent
|
|
directory. This should make backing up wallets more straightforward than
|
|
before because the specified wallet path can just be directly archived without
|
|
having to look in the parent directory for transaction log files.
|
|
|
|
For backwards compatibility, wallet paths that are names of existing data files
|
|
in the `-walletdir` directory will continue to be accepted and interpreted the
|
|
same as before.
|
|
|
|
Low-level RPC changes
|
|
---------------------
|
|
|
|
- When bitcoin is not started with any `-wallet=<path>` options, the name of
|
|
the default wallet returned by `getwalletinfo` and `listwallets` RPCs is
|
|
now the empty string `""` instead of `"wallet.dat"`. If bitcoin is started
|
|
with any `-wallet=<path>` options, there is no change in behavior, and the
|
|
name of any wallet is just its `<path>` string.
|
|
|
|
### Logging
|
|
|
|
- The log timestamp format is now ISO 8601 (e.g. "2018-02-28T12:34:56Z").
|
|
|
|
Miner block size removed
|
|
------------------------
|
|
|
|
The `-blockmaxsize` option for miners to limit their blocks' sizes was
|
|
deprecated in V0.15.1, and has now been removed. Miners should use the
|
|
`-blockmaxweight` option if they want to limit the weight of their blocks'
|
|
weights.
