Remove the pnext pointer in CBlockIndex, and replace it with a
vBlockIndexByHeight vector (no effect on memory usage). pnext can
now be replaced by vBlockIndexByHeight[nHeight+1], but
FindBlockByHeight becomes constant-time.
This also means the entire mapBlockIndex structure and the block
index entries in it become purely blocktree-related data, and
independent from the currently active chain, potentially allowing
them to be protected by separate mutexes in the future.
At startup, check that the expected genesis is loaded. This should prevent
cases where accidentally a datadir from the wrong network is loaded
(testnet vs mainnet, e.g.).
Compiling on my OSX 10.6 build machine, I get:
Undefined symbols:
"boost::chrono::steady_clock::now()", referenced from:
boost::cv_status boost::condition_variable::wait_for<long long, boost::ratio<1ll, 1000000000ll> >(boost::unique_lock<boost::mutex>&, boost::chrono::duration<long long, boost::ratio<1ll, 1000000000ll> > const&)in bitcoinrpc.o
Linking against the boost_chrono fixes the issue.
Windows builds already link against boost_chrono; Linux doesn't, but compiles (on pull-tester / gitian, at least).
A base_uint used to be made of an array of unsigned ints. This works
fine on most platforms, but might not work on certain present or future
platforms. The code breaks if an unsigned int is 16 or 64 bits, so it's
important to be specific. Also changed "u" to "you".
New method in bitcoinrpc: RunLater, that uses a map of deadline
timers to run a function later.
Behavior of walletpassphrase is changed; before, calling
walletpassphrase again before the lock timeout passed
would result in: Error: Wallet is already unlocked.
You would have to call lockwallet before walletpassphrase.
Now: the last walletpassphrase with correct password
wins, and overrides any previous timeout.
Fixes issue# 1961 which was caused by spawning too many threads.
Test plan:
Start with encrypted wallet, password 'foo'
NOTE:
python -c 'import time; print("%d"%time.time())'
... will tell you current unix timestamp.
Try:
walletpassphrase foo 600
getinfo
EXPECT: unlocked_until is about 10 minutes in the future
walletpassphrase foo 1
sleep 2
sendtoaddress mun74Bvba3B1PF2YkrF4NsgcJwHXXh12LF 11
EXPECT: Error: Please enter the wallet passphrase with walletpassphrase first.
walletpassphrase foo 600
walletpassphrase foo 0
getinfo
EXPECT: wallet is locked (unlocked_until is 0)
walletpassphrase foo 10
walletpassphrase foo 600
getinfo
EXPECT: wallet is unlocked until 10 minutes in future
walletpassphrase foo 60
walletpassphrase bar 600
EXPECT: Error, incorrect passphrase
getinfo
EXPECT: wallet still scheduled to lock 60 seconds from first (successful) walletpassphrase
A green testnet splashscreen with a normal, orange dock icon looks strange and can confuse users.

So we stop getting pull requests (like #2604) fixing problems with disabled Script opcodes.
A hard fork would be required to re-enable these, and if we ever did that we'd require extensive review and testing.
When debugging another issue, I found a hang-during-startup race condition due to
LoadWallet calling SetMinVersion (via LoadCryptedKey).
Writing to the file that you're in the process of reading is a bad idea.
Bitcoin-Qt could core dump if application initialization failed in certain ways.
I double-fixed this:
1) qt/bitcoin.cpp now shuts down core threads cleanly if AppInit2 returns false
2) init.cpp now exits before StartNode() if strErrors is set (no reason to StartNode if we're just going to exit immediately anyway).
Tested by triggering all of the various ways AppInit2 can fail, either by passing bogus command-line arguments or just recompiling tweaked code to simulate failure.
This is a partial fix for #2480
Instead of killing a connection when the receive buffer overflows,
just temporarily halt receiving before that happens. Also, no
matter what, always allow at least one full message in the receive
buffer (otherwise blocks larger than the configured buffer size
would pause indefinitely).
It is possible to have a wallet.dat file without any bestblock
record at all (if created offline, for example), which - when
loaded into a client with a up-to-date chain - does no rescan and
shows no transactions.
Also make sure to write the current best block after a rescan, so
it isn't necessary twice.
* Bugfix: output the correct best block hash (during IBD, it can
differ from the actual current best block)
* Add height to output
* Add hash_serialized, which is a hash of the entire UTXO state.
Can be useful to compare two nodes.
* Add total_amount, the sum of all UTXOs' values.
Previously, JSON-RPC clients accessed URI "/", and the JSON-RPC server
did not care about the URI at all, and would accept any URI as valid.
Change the JSON-RPC server to require URI "/" for all current accesses.
This changes enables the addition of future interfaces at different
URIs, such as pull request #1982 which demonstrates HTTP REST wallet
download.
Or, a future, breaking change in JSON-RPC interface could be introduced
by serving JSON-RPC calls from new URI "/v2/".
This value gets stale really quickly, do not hardcode it into a message.
Completely remove it for now.
Later on, a mechanism will be added to determine fees based on the mempool.
Closes#2576
