This script compared paths relative to the report directory to test for exclusion,
meaning the directory exclusions did not work properly, as they were relative to
the project root.
Fix this by creating absolute paths through the combination of:
'git ls-files --full-name' and 'git rev-parse --show-toplevel'
b09dab0f2d Prevent mutex lock fail even if --enable-debug (Akio Nakamura)
Pull request description:
This PR intends to resolve#15227.
```configure --enable-debug``` enables ```#ifdef DEBUG_LOCKORDER```.
Then ```lockdata``` (in sync.cpp) will be initialized same as other static objects.
But unfortunately, ```lockdata.push_lock()``` was called before its initialization (via initializing ```signatureCache``` which is declared in ```script/sigcache.cpp```) on macOS.
This PR apply the "Construct On First Use Idiom" to ```lockdata``` to prevent it.

This PR intends to resolve#15227.
"configure --debug-enabled" enables "#ifdef DEBUG_LOCKORDER".
Then "lockdata" (in sync.cpp) will be initialized same as other
static objects.

When running tests with --usecli, unify the conversion from argument objects to
strings using a new function arg_to_cli(). This fixes boolean arguments when
using named arguments.
Also use json.dumps() to get the string values for arguments that are dicts and
lists so that bitcoind's JSON parser does not become confused.
a36d97d866 Default -whitelistforcerelay to off (Suhas Daftuar)
Pull request description:
No one seems to use this "feature", and at any rate the behavior of relaying transactions when they violate local policy is error-prone, if we ever consider changing the ban behavior of our software from one version to the next.
Defaulting this to off means that users who use -whitelist won't be unexpectedly surprised by this interaction. If anyone is still relying on this feature, it can still be explicitly turned on.

Pull request description:
This documents some information about using the RPC interface securely, as suggested in https://github.com/bitcoin-core/bitcoincore.org/pull/637 by @luke-jr and @TheBlueMatt. I think it should fit in well with #14458, but is not dependent on it (and shouldn't have any significant merge conflicts with it).

fdf82ba18 Update all subprocess.check_output functions in CI scripts to be Python 3.4 compatible (Graham Krizek)
Pull request description:
CI is failing the `lint` stage on every Cron run (regular PR/Push runs still pass). The failure was introduced in 74ce326 and has been broken since. The Python version running in CI was downgraded to 3.4 from 3.6. There were a couple files that were using the `encoding` argument in the `subprocess.check_output` function. This was introduced in Python 3.6 and therefore broke the scripts that were using it. The `universal_newlines` argument was used as well, but in order to use it we must be able to set encoding because of issues on some BSD systems.
To get CI to pass, I removed all `universal_newline` and `encoding` args to the `check_ouput` function. Then I decoded all `check_output` return values. This should keep the same behavior but be Python 3.4 compatible.

keypool runs out, etc.), notify the GUI that the keypool has changed. The

da6011826a Fix macOS launch-at-startup memory issue (Jonas Schnelli)
516437a1b7 Qt: remove macOS launch-at-startup option when compiled with > macOS 10.11 (Jonas Schnelli)
Pull request description:
The launch-at-startup API Bitcoin Core uses on macOS where removed in macOS 10.11 leading to a segmentation-fault due to the weak-linking when not actively compiled against SDK 10.11 (`-mmacosx-version-min=10.11`)
This PR removes the launch-at-startup feature on macOS when compiled with macOS min version > 10.11 (the default is always the macOS version you compile on).
**The depends built binaries (Gitian) are not affected since we are building with min macOS 10.10.**
Users self compiling on macOS > 10.11 can re-enable the feature by compiling with min version <= 10.11 (`CXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" ./configure`)
**Isn't there a new API from Apple?**
Yes, [there is](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLoginItems.html).
It will require to create a helper application which needs to be embedded in the .app folder (needs code signing as well). Developers willing to go down that rabbit hole are welcome.

This allows incoming connections from peers which are only banned
due to an automatic misbehavior ban if doing so won't fill inbound.
These peers are preferred for eviction when inbound fills, but may
still be kept if they fall into the protected classes. This
eviction preference lasts the entire life of the connection even
if the ban expires.
If they misbehave again they'll still get disconnected.
The main purpose of banning on misbehavior is to prevent our
connections from being wasted on unhelpful peers such as ones
running incompatible consensus rules. For inbound peers this
can be better accomplished with eviction preferences.
A secondary purpose was to reduce resource waste from repeated
abuse but virtually any attacker can get a nearly unlimited
supply of addresses, so disconnection is about the best we can
do.
Introduces `TestNode.profile_with_perf()` context manager which
samples node execution to produce profiling data.
Also introduces a test framework flag, `--perf`, which will run
perf on all nodes for the duration of a given test.

b301950df3 Made expicit constructor CTransaction(const CMutableTransaction &tx). (lucash-dev)
faf29dd019 Minimal changes to comply with explicit CMutableTransaction -> CTranaction conversion. (lucash-dev)
Pull request description:
This PR is re-submission of #14156, which was automatically closed by github (glitch?)
Original description:
This PR makes explicit the now implicit conversion constructor `CTransaction(const CMutableTransaction&)` in `transaction.h`.
Minimal changes were made elsewhere to make the code compilable. I'll follow up with other PRs to address individually refactoring functions that should have a `CMutableTransaction` version, or where a `CTransaction` should be reused.
The rationale for this change is:
- Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
- This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
- Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
- Making it explicit allows for easier reasoning of performance trade-offs.
- There has been previous performance issues caused by unneeded use of this implicit conversion.
- This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

Pull request description:
This does not remove OpenSSL, but makes our own PRNG the 'main' one; for GetStrongRandBytes, the OpenSSL RNG is still used (indirectly, by feeding its output into our PRNG state).
It includes a few policy changes (regarding what entropy is seeded when).
Before this PR:
* GetRand*:
* OpenSSL
* GetStrongRand*:
* CPU cycle counter
* Perfmon data (on Windows, once 10 min)
* /dev/urandom (or equivalent)
* rdrand (if available)
* From scheduler when idle:
* CPU cycle counter before and after 1ms sleep
* At startup:
* CPU cycle counter before and after 1ms sleep
After this PR:
* GetRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* GetStrongRand*:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* From scheduler when idle:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter before and after 1ms sleep
* Perfmon data (on Windows, once every 10 min)
* At startup:
* Stack pointer (which indirectly identifies thread and some call stack information)
* rdrand (if available)
* CPU cycle counter
* /dev/urandom (or equivalent)
* OpenSSL
* CPU cycle counter again
* Perfmon data (on Windows, once every 10 min)
The interface of random.h is also simplified, and documentation is added.
This implements most of #14623.
