Give each address a single fixed location in the new and tried tables,
which become simple fixed-size arrays instead of sets and vectors.
This prevents attackers from having an advantages by inserting an
address multiple times.

Make sure that chainparams and logging is properly initialized. Doing
this for every test may be overkill, but this initialization is so
simple that that does not matter.
This should fix the travis issues.
. Closes the bug from commit e179eb3d9b
("bitcoin-qt -help" did not show any message)
. Move all the options in init.cpp (there were already some
options related to bitcoin-qt)
Help messages are formatted programmatically with FormatParagraph
in order not to break existing strings in Transifex.
The new format works even if the translation of the strings
modifies the lenght of the message.
Sqashed 6 commits in a single one.
Help messages correctly formatted for SVGA text mode (132 chars)
Help messages are formatted programmatically with FormatParagraph
in order not to break existing strings in Transifex.
The new format should work even if the translation of the strings
modifies the lenght of the message.
Fix - syntax error
Correct formatting for 79 chars
Correctly based on C++ functions
Removed spare spaces from option strings
Fix - syntax error
When re-indexing, there are a few cases where garbage data may be skipped in
the block files. In these cases, the indices are correctly written to the index
db, however the pointer to the next position for writing in the current block
file is calculated by adding the sizes of the valid blocks found.
As a result, when the re-index is finished, the index db is correct for all
existing blocks, but the next block will be written to an incorrect offset,
likely overwriting existing blocks.
Rather than using the sum of all valid blocks to determine the next write
position, use the end of the last block written to the file. Don't assume that
the current block is the last one in the file, since they may be read
out-of-order.
UNITTEST parameter are not used by any current tests, and the model
(modifyable parameters) is inconvenient when unit-testing. As
they are stored in a global structure eevery test
would have to (re)set up its own parameters.
For consistency it is also better to test with MAIN parameters.

We've chosen to htons/ntohs explicitly on reading and writing
(I do not know why). But as READWRITE already does an endian swap
on big endian, this means the port number gets switched around,
which was what we were trying to avoid in the first place. So
to make this compatible, serialize it as FLATDATA.
- Detect endian instead of stopping configure on big-endian
- Add `byteswap.h` and `endian.h` header for compatibility with
Windows and other operating systems that don't come with them
- Update `crypto/common.h` functions to use compat
endian header
This was added a while ago for testing purposes, but was never intended to be
used. Remove it until upstream libsecp256k1 decides that verification is
stable/ready.
These dialogs will be something that people occasionally open, not keep
open during their session, so just popping it up in a sensible place
is good enough. Remembering only creates potential issues, like spawning
it outside the current screen area.
On Ubuntu this causes the dialogs to be positioned in the
middle of the main dialog, so I didn't add code for that. YMMV.

Code to avoid calling Perfmon too often is only needed when perfmon is actually going to get called.
This is not intended to make any functional difference in the addition of entropy to the random pool.
Backwards-compatibility for libstdc++ is not limited to straightforward abi
changes. Symbol visibility also needs to be taken into consideration, and
that really can't be addressed simply.
Instead, just static-link libstdc++ for backwards-compat.
Split GetNextWorkRequired() into two functions to allow the difficulty calculations to
be tested without requiring a full blockchain.
Add unit tests to cover basic difficulty calculation, plus each of the min/max actual
time, and maximum difficulty target conditions.
This makes it easier for us to replace it if desired, since it's now only in
one spot. Also, it avoids the openssl include from allocators.h, which
essentially forced openssl to be included from every compilation unit.
The fix to NegateSignatureS caused a test which had been failing
in IsValidSignatureEncoding to then fail in IsLowDERSignature.
Add new test so the original check remains exercised.
NegateSignatureS is called with a signature without a hashtype, so
do not save the last byte and append it after S negation.
Updates the two tests which were affected by this bug.
Normally bitcoin core does not display any network originated strings without
sanitizing or hex encoding. This wasn't done for strcommand in many places.
This could be used to play havoc with a terminal displaying the logs,
especially with printtoconsole in use.
Thanks to Evil-Knievel for reporting this issue.
The only time when a client sends a "getaddr" message is when he
esatblishes an Outbound connection (see ProcessMessage() in
src/main.cpp). Another bitcoin client is expected to receive a
"getaddr" message only on Inbound connection. Ignoring "gettaddr"
requests on Outbound connections can resolve potential privacy issues
(and as was said such request normally do not happen anyway).
- rework the function to not log errors but use throw JSONRPCError
- remove a check for IsLocked() that is done in sendtoaddress and
sendfrom RPC calls already
- cache GetBalance() return value, because it's possibly used twice
Bitcoin amounts are stored as uint64 in the protobuf messages (see
paymentrequest.proto), but CAmount is defined as int64_t. Because
of that we need to verify that single and accumulated amounts are
in a valid range and no variable overflow has happened.
- fixes#5624 (#5622)
Thanks @SergioDemianLerner for reporting that issue and also supplying us
with a possible solution.
- add static verifyAmount() function to PaymentServer and move the logging
on error into the function
- also add a unit test to paymentservertests.cpp
c++11 (libc++'s stdlib implementation anyway) doesn't allow for map types to be
forward-declared. for example:
class foo;
std::map<int, foo> bar; // error, foo has not been defined.
class foo{};
Since CWallet and CWalletTx are inter-dependent, but only std::map<*,CWalletTx>
is used, forward-declare CWallet instead and define CWalletTx first.
Despite the mangled git diff, this change only amounts to moving ~320 lines in
a single chunk.
Instead, create a separate function that applies the undo operation of a
CTxInUndo object onto a CCoinsViewCache. This method is used from
DisconnectBlock.
This fixes a potential race condition in the CCheckQueueControl constructor,
which was looking directly at data in CCheckQueue without acquiring its lock.
Remove the now-unnecessary friendship for CCheckQueueControl
Note that this will also require translation changes in Transifex for the key
"A fee higher than %1 is considered an insanely high fee." which is now
"A fee higher than %1 is considered an absurdly high fee."
