Simplify bswap_16 implementation on platforms which don't already have it defined.
This has no effect on the generated assembly; it just simplifies the source code.
Use POSIX rename atomicity at the `bitcoind` side to create a working
cookie atomically:
- Write `.cookie.tmp`, close file
- Rename `.cookie.tmp` to `.cookie`
This avoids clients reading invalid/partial cookies as in #11129.
1. Calculate nblocks more adaptive.
If not specify nblocks-parameter, illegal parameter error
will happen when target block height is below blocks for 1 month.
To avoid this error, set default nblocks to
min(blocks for 1 month, target block's height - 1)
And allowing 0 so that this RPC works good even if target block is
genesis block or 1st block.
2. Correct error message.
nblocks accepts [0 .. block's height -1] . so fix as following:
"Invalid block count: should be between 0 and the block's height - 1"
3. Add check 0-divide.
If nTimeDiff = 0 then returns {... "txrate":} and
bitcoin-cli cannot handle the response.
To avoid this error, do not return "txrate" if nTimeDiff = 0.
4. Add following 3 elements to the return object.
1) 'window_block_count' : Size of the window in number of blocks.
2) 'window_tx_count' : The number of transactions in the window.
3) 'window_interval' : The elapsed time in the window.
They clarify how 'txrate' is calculated. 2) and 3) are returned
only if 'window_block_count' is a positive value.
5. Improve help text for 'time' as following.
'The timestamp for the final block in the window in UNIX format.
CWallet::MarkConflicted may acquire the cs_main lock after
CWalletDB::LoadWallet acquires the cs_wallet lock during wallet initialization.
(CWalletDB::LoadWallet calls ReadKeyValue which calls CWallet::LoadToWallet
which calls CWallet::MarkConflicted). This is the opposite order that cs_main
and cs_wallet locks are acquired in the rest of the code, and so leads to
POTENTIAL DEADLOCK DETECTED errors if bitcoin is built with -DDEBUG_LOCKORDER.
This commit changes CWallet::LoadWallet (which calls CWalletDB::LoadWallet) to
acquire both locks in the standard order. It also fixes some tests that were
acquiring wallet and main locks out of order and failed with the new locking in
CWallet::LoadWallet.
Error was reported by Luke Dashjr <luke-jr@utopios.org> in
https://botbot.me/freenode/bitcoin-core-dev/msg/90244330/
In a signature, it contains an ASN1 integer which isn't strict-DER conformant due to excessive 0xff padding:

Instead of passing a StartShutdown reference all the way up from
txdb, give ShowProgress a "resumeable" boolean, which is used to
inform the user if the action will be resumed, but cancel is always
allowed by just calling StartShutdown().
Removes vchDefaultKey which was only used for first run detection.
Improves wallet first run detection by checking to see if any keys
were read from the database.
This will now also check for a valid defaultkey for backwards
compatibility reasons and to check for any corruption.
Keys will stil be generated on the first one, but there won't be
any shown in the address book as was previously done.
Only change in behavior is that unsupported combinations of parameters now
trigger more specific error messages instead of the vague "JSON value is not a
string as expected" error.
This changes RPC methods to treat null arguments the same as missing arguments,
instead of throwing type errors. Specifically:
- `getbalance` method now returns the wallet balance when the `account` param
is null instead of throwing a type error (same as when parameter is missing).
It is still an error to supply `minconf` or `watchonly` options when the
account is null.
- `addnode` and `setban` methods now return help text instead of type errors if
`command` params are null (same as when params are missing).
- `sendrawtransaction`, `setaccount`, `movecmd`, `sendfrom`,
`addmultisigaddress`, `listaccounts`, `lockunspent` methods accept null
default values where missing values were previously allowed, and treat them
the same.
This commit just moves a few function declarations and updates callers.
Function bodies are moved in two followup MOVEONLY commits.
This change is desirable because wallet.h/cpp are monolithic and hard to
navigate, so pulling things out and grouping together pieces of related
functionality should improve the organization.
Another proximate motivation is the wallet process separation work in
https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially)
parameter parsing and fee estimation are still done in the main process rather
than the wallet process, and having functions that run in different processes
scrambled up throughout wallet.cpp is unnecessarily confusing.
Currently difficulty adjustment violations are not reported for
chains that branch off before the last checkpoint. Change this
by moving the checkpoint check after the difficulty check.
