Outbound peer logic prevents connecting to addresses that we're already
connected to, so prevent inadvertent eviction of current peers via
test-before-evict by checking this condition and marking current peer's
addresses as Good().
Co-authored-by: John Newbery <john@johnnewbery.com>
Being able to invoke Good() is important for address management (new vs tried
table, tried table eviction via test-before-evict). We mitigate potential
information leaks by not calling Connected() on these peer addresses.
Starting with the Clang shipped with Xcode 12, Apple has enabled
-Werror=implicit-function-declaration by default. This causes bdbs mutex
detection to fail when building on macOS (not cross-compiling):
checking for mutexes... UNIX/fcntl
configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM.
configure: error: Unable to find a mutex implementation
as previously emitted warnings are being turned into errors. i.e:
error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration]
Append -Wno-error=implicit-function-declaration to cflags so that
-Wimplicit-function-declaration returns to being a warning, and the
configure checks will succeed.
Fixes #19411.

Since m_check_ratio is only set once and since the CTxMemPool object is
no longer a global variable, m_check_ratio can be passed into the
constructor of CTxMemPool. Since it is only read from after
initialization, m_check_ratio can also be made a const and hence no
longer needs to be guarded by the cs mutex.
56a461f72796ca60de28e78f144741eb1a4f5213 wallet: fix buffer over-read in SQLite file magic check (Sebastian Falbesoner)
Pull request description:
Looking at our new SQLite database code, I noticed that there is a potential problem in the method `IsSQLiteFile()`: If there is no terminating zero within the first 16 bytes of the file, the `magic` buffer would be over-read in the `std::string` constructor for `magic_str`. Fixed by using the "from buffer" variant of the string ctor (that also takes a size) rather than the "from c-string" variant (see http://www.cplusplus.com/reference/string/string/string/).
The behaviour can be reproduced by the following steps:
* Creating a file of at least 512 bytes in size (to pass the minimum size check) that doesn't contain zero bytes in the magic area, e.g. simply:
`$ python3 -c "print('A'*512)" > /tmp/corrupt_wallet`
* Showing content and size of the `magic_str` string in case the magic check fails
* Create a simple unit test that simply calls `IsSQLiteFile` with the corrupt wallet file
* Run the unit test and see the random gibberish output of `magic_str` after 16 `A`s :-)
Or, TLDR variant, just get the branch https://github.com/theStack/bitcoin/tree/reproduce_sqlite_magic_overread, compile unit Tests and run the script `./reproduce_sqlite_magic_overread.sh`.
Note that this is the minimal diff, probably it would be better to avoid `std::string` at all in this case and just use `memcmp`, strings that include null bytes are pretty confusing.

Pull request description:
> decimal is preferred in accounting applications
https://docs.python.org/3.8/library/decimal.html
Decimal type saves an exact value so better than using float.
~~3 variables declared with type as 'Decimal' in [test/functional/mempool_accept.py](https://github.com/bitcoin/bitcoin/blob/master/test/functional/mempool_accept.py): fee, fee_expected, output_amount~~
~~Not required to convert to string anymore for using the above variables as decimal~~
+ fee, fee_expected, output_amount
~~+ 8 decimal places~~
+ Using value of coin['amount'] as decimal and removed 'int'
+ Removed unnecessary parentheses
+ Remove str() and use quotes
