a029805f57fa9a4ab9867c0d1e865675d57537c7 build: remove -Qunused-arguments workaround for clang + ccache (fanquake)
Pull request description:
This was added in 386efb7695 to address spammy Clang warnings when building with ccache.
The issue was addressed in [ccache 3.2](https://bugzilla.samba.org/show_bug.cgi?id=8118), and from a look at most major distros, it's only Debian Jessie that has a version of ccache older than that ([3.1](https://packages.debian.org/jessie/ccache)).
Therefore I think it's acceptable to drop this workaround, and re-enable warnings for unused driver arguments (when compiling using Clang and ccache).

Pull request description:
Current approach
- copy accumulated `ret` vector to `arrTmp`
- drop unnecessary elements from `arrTmp`
- reverse `arrTmp`
- clear `ret`
- copy `arrTmp` to the `ret`
New approach
- create a vector from the accumulated `ret` with just the necessary elements already reversed
- copy it to the result
This PR doesn't change behavior.

ac57859e53167f4ff3da467b616b0902c93701a9 qt: Fix deprecated QCharRef usage (Hennadii Stepanov)
Pull request description:
From Qt docs:
- [`QKeyEvent::text()`](https://doc.qt.io/qt-5/qkeyevent.html#text):
> Return values when modifier keys such as Shift, Control, Alt, and Meta are pressed differ among platforms and could return an empty string.
- [`QString::operator[]()`](https://doc.qt.io/qt-5/qstring.html#operator-5b-5d):
> **Note:** Before Qt 5.14 it was possible to use this operator to access a character at an out-of-bounds position in the string, and then assign to such a position, causing the string to be automatically resized. Furthermore, assigning a value to the returned `QCharRef` would cause a detach of the string, even if the string has been copied in the meanwhile (and the `QCharRef` kept alive while the copy was taken). These behaviors are deprecated, and will be changed in a future version of Qt.
Since Qt 5.14 this causes a `QCharRef` warning if any modifier key is pressed while the splashscreen is still displayed.
Fix#18080.
Note: Ctrl+Q will also close the spashscreen now.

b3c4d9bac6910f6c28f6008c5ca7064a315fd2a5 test: rename test suite name "tx_validationcache_tests" to match filename (Sebastian Falbesoner)
Pull request description:
Quoting `src/test/README.md`, '`Adding test cases`':
> "The file naming convention is `<source_filename>_tests.cpp`
> and such files should wrap their tests in a test suite
> called `<source_filename>_tests`."
Currently the unit test source file `txvalidationcache_tests.cpp` contains a unit test suite with the name `tx_validationcache_tests`, which is fixed by this PR. The following shell script shows that this is the only mismatch and for all other unit test source files the test suite names are correct:
```
#!/bin/bash
shopt -s globstar
for test_full_filename in **/*_tests.cpp; do
test_name_file=`basename $test_full_filename .cpp`
test_name_suite=`sed -n "s/^.*TEST_SUITE(\(.*_tests\).*$/\1/p" $test_full_filename`
if [ $test_name_file != $test_name_suite ]; then
echo "TestFilename: $test_name_file != TestSuitname: $test_name_suite"
fi

Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always welcome.
* All other changes should have accompanying unit tests (see `src/test/`) or
functional tests (see `test/`). Contributors should note which tests cover
modified code. If no tests exist for a region of modified code, new tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or an
explanation of the potential issue as well as reasoning for the way the bug
was fixed.
* Features are welcome, but might be rejected due to design or scope issues.
If a feature is based on a lot of dependencies, contributors should first
consider building the system outside of Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.

<!--
Bitcoin Core has a thorough review process and even the most trivial change
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so
patches often sit for a long time.

582e66b6e75d58033987a7b0474226cfdd724ce0 doc: Added regtest config for linearize script (Gr0kchain)
Pull request description:
Updated the example-linearize.cfg file to include support for the regtest chain network config which is used by the ./linearize-data.py
Problem:
Without the regtest magic, genesis hash and path config, the `linearize-data.py` script cannot generate a bootstrap.dat file.
Example:
./linearize-data.py ./linearize.cfg
Read 102 hashes
Genesis block not found in hashlist
Solution:
Added netmagic, genesis and input example parameters to file.
Resolution
1. Starting bitcoind in regtest mode
2. bitcoin-cli generatetoaddress 101 $(bitcoin-cli getnewaddress)
3. ./linearize-hashes.py ./linearize.cfg > ./hashlist.txt
4. ./linearize-data.py ./linearize.cfg
```
$ ./linearize-data.py ./linearize.cfg
Read 102 hashes
Input file /Users/gr0kchain/.bitcoin/regtest/blocks/blk00000.dat
Output file /Users/gr0kchain/Downloads/bootstrap.dat
Done (102 blocks written)
```

*** Please remove the following help text before submitting: ***
Pull requests without a rationale and clear improvement may be closed

<!--
Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always welcome.
* All other changes should have accompanying unit tests (see `src/test/`) or
functional tests (see `test/`). Contributors should note which tests cover
modified code. If no tests exist for a region of modified code, new tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or an
explanation of the potential issue as well as reasoning for the way the bug
was fixed.
* Features are welcome, but might be rejected due to design or scope issues.
If a feature is based on a lot of dependencies, contributors should first
consider building the system outside of Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.

When bitcoind is running in pruned mode, producing a hashlist with `./linearize-hashes.py linearize.cfg > hashlist.txt` and then executing `linearize-data.py linearize.cfg` will produce:
```
Read 313001 hashes
Input file /home/dan/.bitcoin/blocks/blk00000.dat
Premature end of block data
```
This happens because `linearize-data` starts by attempting to process `blk00000.dat` regardless of whether or not `blk00000.dat` actually exists - this may not be the case if working with a pruned node.
This PR adds a function which finds the first block file that does exist, and calls that function when the `BlockDataCopier` is initialized.
This is a refactor of #16431.
<!--
Bitcoin Core has a thorough review process and even the most trivial change
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so
patches often sit for a long time.

Pull request description:
We use build macros such as `AX_CHECK_LINK_FLAG`, that require >=2.64, so our configure should also require Autoconf >= 2.64. The build would already blow up if 2.64 wasn't available. i.e:
```bash
configure.ac:320: error: Autoconf version 2.64 or higher is required
build-aux/m4/ax_check_link_flag.m4:74: AX_CHECK_LINK_FLAG is expanded from...

For reference, Autoconf 2.69 was released in [April of 2012](https://lists.gnu.org/archive/html/autoconf/2012-04/msg00041.html).

fcb72616253ed22e364bc312992d77efc1c4a3c1 Prevent valgrind false positive in rest_blockhash_by_height (Russell Yanofsky)
Pull request description:
A bad interaction between valgrind and clang 6.0.0-1ubuntu2 with -O2 optimizations makes valgrind misleadingly imply C++ code is reading an uninitialized blockheight value in `rest_blockhash_by_height` just because that's what clang optimized code is doing. The C++ code looks like:
```c++
int32_t blockheight;
if (!ParseInt32(height_str, &blockheight) || blockheight < 0) {
```
while the optimized code looks like:
```
0x00000000000f97ab <+123>: callq 0x4f8860 <ParseInt32(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int*)>

0x00000000000f97b4 <+132>: test %ebx,%ebx
0x00000000000f97b6 <+134>: js 0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>
0x00000000000f97bc <+140>: xor $0x1,%al
0x00000000000f97be <+142>: jne 0xf98aa <rest_blockhash_by_height(util::Ref const&, HTTPRequest*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)+378>
```
During the rest_interface.py test:
eef90c14ed/test/functional/interface_rest.py (L266)
when `height_str` is empty, `ParseInt32` returns false and `blockheight` value is never assigned. The optimized code reads the uninitialized `blockheight` value in `0xc(%rsp)` before the checking the `ParseInt32` return value in `%al`, which is harmless, but triggers the following error from valgrind:

This is a known bad interaction between clang and valgrind. The clang optimized code is correct but valgrind has no way of knowing that accessing the uninitialized value isn't a problem. Issue has been reported previously:
- https://bugs.llvm.org/show_bug.cgi?id=32604#c4
- https://github.com/Z3Prover/z3/issues/972
This commit just sets blockheight to -1 as a workaround.
This change was originally made in 41d5d651594c6c939add7a58b7e30c97dccdf24a from #18740 to fix the travis error there (https://travis-ci.org/github/bitcoin/bitcoin/jobs/678453061#L7157) but MarcoFalke suggested https://github.com/bitcoin/bitcoin/pull/18740#discussion_r414772851 moving to a new PR, since apparently the error's been seen on travis previously

f65c9ad40f2f5cdc581bdaf72e7dc68e9d7f7a80 Check for overflow when calculating sum of outputs (Elichai Turkel)
Pull request description:
This was reported by practicalswift here #18046
The exact order of the if, is important, we first do `!MoneyRange(tx_out.nValue)` to make sure the amount is non-negative. and then `std::numeric_limits<CAmount>::max() - tx_out.nValue < nValueOut` checks that the addition cannot overflow (if we won't check that the amount is positive this check can also overflow! (by doing something like `max - -max`))
and only then we make sure that the some is also valid `!MoneyRange(nValueOut + tx_out.nValue)`
if any of these conditions fail we throw.
the overflowing logic:
```
a + b > max // we want to fail if a+b is more than the maximum -> will overflow
b > max - a
max - a < b
```

e980214bc4fd49530e8d50fe0a6657b8583bc6b5 serialization: prevent int overflow for big Coin::nHeight (pierrenn)
Pull request description:
This is an attempt to fix fuzzer issues 1,2,8 reported by practicalswift here : https://github.com/bitcoin/bitcoin/issues/18046
The fuzzer harness doesn't prevent deserialization of unrealistic high values for `Coin::nHeight`. In the [provided examples](https://github.com/bitcoin/bitcoin/issues/18046), we have :
- `blockundo_deserialize` : the varint `0x8DD88DD700` is deserialized as `3944983552` in `Coin::nHeight` (`TxInOutFormatter::Unser`)
- `coins_deserialize` : the varint `0x8DD5D5EC40` is deserialized as `3939874496` similarly
- `txundo_deserialize`: the varint `0x8DCD828F01` is deserialized as `3921725441` in `Coin::nHeight` (`Coin::Unserialize`)
Since `Coin::nHeight` is 31 bit long, multiplying a large value by 2 triggers the fuzzer.
AFAIK those values are unrealistic (~70k years for the smallest..). I've looked a bit a reducing the range of values the fuzzer can deserialize, but this seems to be too much code change for not much.
Hence this PR chooses to static cast `nHeight` when re-serializing; it seems to be the less intrusive/safest way to prevent the fuzzer output.
Another more "upstream" approach would be to limit `Coin::nHeight` values to something more realistic, e.g. `0xFFFFFFF` (~5k years) :
de3a30bab2/src/undo.h (L39) and de3a30bab2/src/coins.h (L71)
Thanks !
NB: i was also not sure about the component/area to prefix the PR/commit with.. ?

7a6627ae87b637bf32c03122865402bd71adf0d1 Fix mining to an invalid target + ensure that a new block has the correct hash internally in Python tests (Samer Afach)
Pull request description:
Test with block 47 in the `feature_block.py` creates a block with a hash higher than the target, which is supposed to fail. Now two issues exist there, and both have low probability of showing up:
1. The creation is done with `while (hash < target)`, which is wrong, because hash = target is a valid mined value based on the code in the function `CheckProofOfWork()` that validates the mining target:
```
if (UintToArith256(hash) > bnTarget)
return false;
```
2. As we know the hash stored in CBlock class in Python is stateful, unlike how it's in C++, where calling `CBlock::GetHash()` will actively calculate the hash and not cache it anywhere. With this, blocks that come out of the method `next_block` can have incorrect hash value when `solve=False`. This is because the `next_block` is mostly used with `solve=True`, and solving does call the function `rehash()` which calculates the hash of the block, but with `solve=False`, nothing calls that method. And since the work to be done in regtests is very low, the probably of this problem showing up is very low, but it practically happens (well, with much higher probability compared to issue No. 1 above).
This PR fixes both these issues.

ddc7e42d600a0cb3e763cda0dc04a1f2f34e9440 build: Set minimum Automake version to 1.13 (Hennadii Stepanov)
Pull request description:
This PR suggests to set the required minimum Automake version to `1.13` explicitly for the following reasons:
- it guarantees that [CVE-2012-3386](https://lists.gnu.org/archive/html/automake/2012-07/msg00023.html) has been fixed
- `AC_CONFIG_MACRO_DIR` macro support, which we already use; from the [release notes](https://lists.gnu.org/archive/html/automake/2012-12/msg00038.html):
> Improvements to aclocal and related rebuilds rules:
> - Autoconf-provided macros AC_CONFIG_MACRO_DIR and AC_CONFIG_MACRO_DIRS are now traced by aclocal, and can be used to declare the local m4 include directories. Formerly, one had to specify it with an explicit '-I' option to the 'aclocal' invocation.
- `AM_SILENT_RULES` macro support (since version `1.11`)
Automake `1.13` requires Autoconf `2.65` or greater. We already have `2.69` since #17769.

For reference, Automake `1.13` was released in [December of 2012](https://lists.gnu.org/archive/html/automake/2012-12/msg00038.html).
CentOS 7 uses Automake [`1.13.4`](https://centos.pkgs.org/7/centos-x86_64/automake-1.13.4-3.el7.noarch.rpm.html)

ACK ddc7e42d600a0cb3e763cda0dc04a1f2f34e9440 - I think adding a minimum required version here is fine. I'd be surprised if someone who is currently building Bitcoin Core was unable to after this change.

aff2748f8aee72f03b5fb6f6f97f0d0f66391755 httpserver: use own HTTP status codes (Filip Gospodinov)
Pull request description:
Before, macros defined in `<event2/http.h>` have been used for some HTTP status codes. `<event2/http.h>` is included implicitly and the usage of its status code macros is inconsistent with the majority HTTP response implementations in this file.
Now, the `HTTPStatusCode` enum from `<rpc/protocol.h>` is consistently used for all HTTP response implementations.
