Subject: [PATCH 019/688] Fix P2P::ManagerBase::stop() race condition

This solves a race condition by making sure that during stop() the
P2P::ManagerBase's thread pool waits for all tasks to be flushed
out before its Session objects are closed and the underlying
networking component is destroyed.

+/**
+ *  OrbiterSDK Network Simulator
+ *  Built to stress and test the capabilities of the OrbiterSDK network
+ *  It requires a running instance OrbiterSDK network to connect to (AIO-setup.sh is recommended for local instances)
+ *  It works as following:
+ *  1. The simulator will setup a given number of accounts (Packet size * Worker size)
+ *     with a given amount of native tokens using the chain owner private key.
+ *  2. The simulator will then create X workers where each worker
+ *     will send a "packet" containing one transaction from each account to the chain owner, given that worker HTTP port
+ *     containing a given amount of native tokens.
+ *  3. Each worker will follow the following cycle:
+ *    - Create a packet containing a transaction from each account to the chain owner
+ *    - Send the packet containing the transactions through the respective worker HTTP port
+ *    - Wait for the packet to be confirmed by the network
+ *
+ *  4. The simulator will count and print the following
+ *     - Packet creation time
+ *     - Packet send time
+ *     - Packet confirmation time
+ *     - Total time
+ *
+ * When executing the simulator, it will ask for the following parameters:
+ * 1. Chain owner PrivKey: The private key of the chain owner
+ * 2. Chain ID: The ID of the chain to connect to (for transactions)
+ * 3. Packet size: The number of transactions to send in each packet (also the number of accounts to create)
+ * 4. Packet count: The number of packets to send
+ * 5. Init Native balance (wei): The amount of native tokens to send to each account
+ * 6. Tx Native balance (wei): The amount of native tokens to send in each transaction
+ * 7. Worker threads: The number of worker threads to use to create/send the packets
+ * 8. HTTP IP:PORT: The IP and port of each worker HTTP server
+ *

Subject: [PATCH 044/688] Internal refactor of P2P::Session vs. P2P::ManagerXXX
 classes (#93)

* Replace weak_ptr<Session> with NodeId in Manager* APIs

* Fix SonarQube issue

* Remove retrieving session object for logging errors

* Harden P2P networking shutdown sequence

- Rule out any possibility that ManagerBase::sessions_ will
grow (or shrink) after ManagerBase::close_ is set to true, so that
ManagerBase::stop() can close all registered sessions

- On ManagerBase::stop(), join the Session thread pool after
Server and ClientFactory are stopped (possibly more correct)

* P2P::ManagerBase:

- removed closed_; replaced by started_ (ManagerBase should be
able to start() and stop() repeatedly and safely)
- added stateMutex_ to synchronize start(), stop() and thread pool
- start() creates threadPool_
- stop() destroys threadPool_ (waits for all tasks and joins all
threads, guaranteeing that there is no session/socket message
handling code active when it is time to e.g. destroy the
underlying io_context)
- threadPool_ is now isolated and not forwarded to other objects;
to use the ManagerBase thread pool, other objects have to call a
method on ManagerBase that will service the request, such as
ManagerBase::asyncHandleMessage()

state.cpp (test):

- increased timeout from 5s to 120s in a couple of futures to
avoid random, performance-related failures (logs to cout if they
exceed 5s, which in any case is rare)

* add this->

Subject: [PATCH 101/688] Work on NodeConns

- NodeConns is now a component of ManagerNormal
- Finished BroadcastInfo (but it will probably will be removed/useless)
- Added Notify/Notification as a new P2P message type
- Added NotifyInfo
- Added NodeConns worker thread (100ms info refresh, 10s timeout)
- NodeConns worker thread lifetime tied to ManagerNormal start()/stop()
- Old code is now NodeConns::forceRefresh() (synchronous NodeInfo refresh)

NOTE: There are test failures.

Subject: [PATCH 114/688] Implement Syncer

- Implemented simple syncer loop that will run on boot
- Added a simple 2-node P2P unit test for the Syncer

TODO:

- Need to ensure connectivity is sufficient before Syncer::sync()
is called by the main thread on node boot; this was not tested.

Subject: [PATCH 171/688] - Move broadcast messages (multi-hop) to a new
 Broadcaster component that is owned by the ManagerNormal P2P engine -
 Syncer::sync() accepts a timeout in seconds (default 15s) to wait for peer
 connections to be established by the DiscoveryWorker -
 NodeConns::forceRefresh() releases the lock when requesting NodeInfo since
 that operation now calls NodeConns also - Refactor net/p2p/encoding.* to
 reuse common (de)serialization code blocks - When node N receives a broadcast
 message from node S, N will (optionally) not rebroadcast that message to any
 one of its peers that is also a peer of S (see:
 ManagerNormal::sendMessageToAll())

Subject: [PATCH 179/688] - Add more logging to Syncer::sync() - The return
 value of methods that try to add both regular and validator transactions to
 the data model is now TxStatus, which contains status codes for both
 transaction types - Changed how Broadcaster decides how to process and
 rebroadcast certain messages - Remove BroadcastInfo (renamed to NotifyInfo,
 essentially) - Changed ManagerBase destructor to virtual - Removed
 ManagerDiscovery destructor - Fix ManagerNormal::sendMessageToAll
 send-to-original-sender - Fix missing break in ManagerNormal::handleMessage()
 - Add NodeType tracking to NodeConns to conform to the existing node list
 serializer/deserializer helper in encoding.* - Misc refactors

Subject: [PATCH 181/688] - Fix deadlock in ManagerBase: stop() vs
 asyncHandleMessage() acquiring stateMutex_ exclusively - Fix rdPoS test that
 waits for 10 blocks the right way - Add Utils::safePrintTest() to print also
 when in testcases - Add missing include guard in net/p2p/client.h - Remove
 some dead code

Subject: [PATCH 186/688] Fix bug introduced in last commit (close session on
 race of block broadcast received by multiple net threads)

- Added BlockValidationStatus enum to state.h to differentiate
between block validation failures due to erroneous data and the
block being of an unexpected height
- Added a State::tryProcessNextBlock() method that returns a
BlockValidationStatus instead of throwing an exception
- Broadcaster uses State::tryProcessNextBlock() to differentiate
block with wrong height (i.e. irrelevant) from receiving bad data

Subject: [PATCH 205/688] Misc improvements and fixes

- Re-enabled logging with Logger::logToDebug()
- Logger now logs to bdk.log with support to rotating log files
via a size limit (backs up to bdk.log.0, bdk.log.1, etc.) and a
log file count limit
- Added command-line argument support to bdkd, bdkd-discovery and
bdkd-tests, with support for custom arguments and custom defaults
for each
  - --help / -h
  - --loglevel / -l: set the verbosity level of bdk.log to one of
    TRACE, DEBUG, INFO, WARNING, ERROR, NONE
  - --loglinelimit: set the maximum number of lines to be logged
    before the log file is rotated/archived
  - --logfilelimit: set the maximum number of log files (active +
    archived) that is kept
- Added custom main() to bdkd-tests, allowing us to e.g. configure
the logging for the tests with command-line args (still able to
pass arguments to Catch2 as well)
- Fixed signal handling (^C) & proper shutdown in bdkd &
bdkd-discovery main thread
- Downgraded multiple logging messages to lower log types
- Fixed several redundant State::validateNextBlock() followed
by State::processNextBlock() (using State::tryProcessNextBlock()
instead, which runs block validation only once; also reduces
logging)
- Fixed missing stopWorker() in DumpWorker::~DumpWorker
- Removed a handful of logging to "log.txt" and redirected them
to the new Logger::logToDebug() ("bdk.log") as TRACE messages
- Added event listeners to Catch2, which log entering and leaving
each TEST_CASE and SECTION as INFO log messages
- Added TempLogLevel helper class to the unit test suite to
help changing the log level temporarily for a test or test scope
- Set temp log level for the last rdPoS test (failing) to TRACE

Subject: [PATCH 210/688] Revamp/improve logging & logging tools

- Introduced several xLOGxxxx() macros that make
logging/printing more informative and convenient
- When logging in the context of a running node, print
an unique #nnn node ID, allowing log messages from different
components (Storage, P2P, Consensus, etc.) to be mapped
to the same running node when looking at networked test
logs, for example
- Misc cleanups
- Added TempEchoToCout helper class to unit test suite
that allows the echoing of test log messages to stdout
(substitutes for uploading "bdk.log" from Github when
running PR tests there)
- Enabled TempEchoToCout temporarily for the last rdPoS
test, which is failing

Subject: [PATCH 213/688] P2P module thread count/control improvements

- Added internal controls for client connection threads,
server acceptor threads, and general I/O threads ("netThreads")
- Client connection threads and server acceptor threads set to 1
- Added global dynamic switch for netThreads
- netThreads set to min(4, hardware_concurrency) by default
- Added command-line argument --netthreads <#> to set netThreads
- Unit tests set netThreads to 1 by default
- Misc refactors & cleanups

+// NOTE (Threading): A relatively low net worker thread count is something you want, in general:
+// - It encourages writing good network messaging handlers;
+// - It encourages writing dedicated thread pools elsewhere in the stack to do heavy processing of
+//   messages *after* they are received (you should never have to do heavy computation in io threads);
+// - It avoids having networked unit tests with a massive number of threads to debug;
+// - Even debugging a single node (with e.g. gdb: thread info, bt, ...) is now much simpler;
+// - Having less threads in general reduces the probability that we need to worry about having
+//   thread scheduling & context switching bottlenecks of any sort;
+// - Having multiple threads helps to hide some kinds of bugs, making them harder to reproduce.
+// But if you want to experiment with larger thread counts, it's just a matter of tweaking the constants below.

Subject: [PATCH 221/688] Misc P2P improvements

- removed posting of Message objects in a separate thread pool
for processing; now handleMessage() is done in the same thread
that pumps the bytes out of the peer socket
- single io_context in P2P::ManagerBase, removed io_context from
P2P::Client and P2P::Server/P2P::ServerListener
- single ASIO thread pool in P2P::ManagerBase, removed threading
 from P2P::Client and P2P::Server
- Removed Client, Server, ServerListener classes, and moved all
networking functionality into a ManagerBase::Net helper class
- Fix bug in Server socket acceptance where an error in accepting
a connection results in the server never accepting a connection again
- Fix Session::do_close()
- Changed logical location logging to append the serverPort_ of the
P2P node after the instance ID# (now logs looks like " #nn:nnnn ")
- Improved several P2P logging messages
- Misc refactors/fixes

+// NOTE (Socket options & socket shutdown):
+// The current implementation is designed to completely avoid the TIME_WAIT TCP socket state by:
+// - Setting the SO_LINGER option to ON on all sockets, with a timeout of zero.
+// - NOT issuing a shutdown() to the socket when closing it and just calling close() straight up.
+// The idea here is that:
+// - Once we decide to kill a connection from one side, then it should be completely dead from
+//   that point on, EVEN if it has pending I/O data somewhere in the local networking stack.
+// - A blockchain node is by definition tolerant to any kind of network failure -- even if it is
+//   self-inflicted. It has to work *regardless* of lost or even maliciously corrupted net data.
+// - If we have a need to guarantee data send/receive before planned (app-explicit, orderly)
+//   shutdown, these acknowledgements should be done by our protocol before we tell the
+//   P2P TCP connection at either end to be closed. We should not depend on the TCP stack to do
+//   any work for us post closing a connection/session. In other words, when the code decides
+//   to close a connection, it should also be the moment where it knows any data that positively
+//   must be acknowledged has been acknowledged by virtue of in-band, application-level (i.e.
+//   above the TCP socket impl) traffic.
+// And besides: if the goal is to, for example, write a server that fulfills a request then
+//   closes the connection, it is probably simpler to combine the client closing the connection
+//   when it receives the data with a timer on the server that closes the connection afer some
+//   time elapsed after the last packet of data is sent. That would be simpler than trying to
+//   orchestrate shutdown() and close(), which you would need to do anyay, and achieve the same
+//   result in practice, which is a very low exercising of retries due to closing while data
+//   is still pending (provided the simple timeout is larger enough, and that most clients are
+//   well-behaved anyway and will close the connection before the timeout).
+// This frees the application from having to deal with SO_REUSEADDR for the TCP listen socket,
+//   and it can just refuse to run if there's a local address/port conflict.

 // NOTE (Threading): A relatively low net worker thread count is something you want, in general:
 // - It encourages writing good network messaging handlers;

-// NOTE (Socket options & socket shutdown):
-// The current implementation is designed to completely avoid the TIME_WAIT TCP socket state by:
-// - Setting the SO_LINGER option to ON on all sockets, with a timeout of zero.
-// - NOT issuing a shutdown() to the socket when closing it and just calling close() straight up.
-// The idea here is that:
-// - Once we decide to kill a connection from one side, then it should be completely dead from
-//   that point on, EVEN if it has pending I/O data somewhere in the local networking stack.
-// - A blockchain node is by definition tolerant to any kind of network failure -- even if it is
-//   self-inflicted. It has to work *regardless* of lost or even maliciously corrupted net data.
-// - If we have a need to guarantee data send/receive before planned (app-explicit, orderly)
-//   shutdown, these acknowledgements should be done by our protocol before we tell the
-//   P2P TCP connection at either end to be closed. We should not depend on the TCP stack to do
-//   any work for us post closing a connection/session. In other words, when the code decides
-//   to close a connection, it should also be the moment where it knows any data that positively
-//   must be acknowledged has been acknowledged by virtue of in-band, application-level (i.e.
-//   above the TCP socket impl) traffic.
-// And besides: if the goal is to, for example, write a server that fulfills a request then
-//   closes the connection, it is probably simpler to combine the client closing the connection
-//   when it receives the data with a timer on the server that closes the connection afer some
-//   time elapsed after the last packet of data is sent. That would be simpler than trying to
-//   orchestrate shutdown() and close(), which you would need to do anyay, and achieve the same
-//   result in practice, which is a very low exercising of retries due to closing while data
-//   is still pending (provided the simple timeout is larger enough, and that most clients are
-//   well-behaved anyway and will close the connection before the timeout).
-// This frees the application from having to deal with SO_REUSEADDR for the TCP listen socket,
-//   and it can just refuse to run if there's a local address/port conflict.
-
-// NOTE (Threading): A relatively low net worker thread count is something you want, in general:
-// - It encourages writing good network messaging handlers;
-// - It encourages writing dedicated thread pools elsewhere in the stack to do heavy processing of
-//   messages *after* they are received (you should never have to do heavy computation in io threads);
-// - It avoids having networked unit tests with a massive number of threads to debug;
-// - Even debugging a single node (with e.g. gdb: thread info, bt, ...) is now much simpler;
-// - Having less threads in general reduces the probability that we need to worry about having
-//   thread scheduling & context switching bottlenecks of any sort;
-// - Having multiple threads helps to hide some kinds of bugs, making them harder to reproduce.
-// But if you want to experiment with larger thread counts, it's just a matter of tweaking the constant below.

Subject: [PATCH 245/688] Fix multiple P2P bugs

- Fix non-synchronized access of Session::socket_ (via single Session::strand_)
- Fix P2P the double connection problem (A-->B connect, B-->A connect, B close inbound, A close inbound)
- Fix P2P multiple outgoing connection problem (A-->B, A-->B, A-->B multiple outbound sessions)
- Fix several synchronization & state-transition problems
- Ensure no ~io_context vs. ~Session (~strand, ~socket) races can occur during ManagerBase::stop()
- Ensure P2P application layer does not receive callbacks from stale/dead sessions
- Code refactoring & polishing

-For older distros, you may need to compile some dependencies from source (specifically CMake, Boost and/or GCC). Make sure to either uninstall them from the system first to prevent any version conflicts, or use a workaround like e.g. Debian's `update-alternatives` or similar.
-
-Specifically for GCC, make sure to also export the right paths for compilation in your environment in case you're using a self-compiled build. For example, in a Linux system, put something like this in your `~/.bashrc` file, changing the version accordingly to whichever one you have installed:
-
-```bash
-PATH=/usr/local/gcc-14.1.0/bin:$PATH
-LD_LIBRARY_PATH=/usr/local/gcc-14.1.0/lib64:$LD_LIBRARY_PATH
-```
+There is a script called `scripts/deps.sh` which you can use to check if you have those dependencies installed (`deps.sh --check`), and install them in case you don't (`deps.sh --install`). The script expects dependencies to be installed either on `/usr` or `/usr/local`, giving preference to the latter if it finds anything there (so you can use a higher version of a dependency while still keeping your distro's default one).
 
-#### One-liners
+**Please note that installing dependencies through the script only works on APT-based distros** (Debian, Ubuntu and derivatives) - you can still check the dependencies on any distro, but installing them requires APT. For distros with other package managers and/or distros older than the minimum ones listed above, you're on your own.
 
-* For APT-based distros:
+If you're using a self-compiled GCC build, don't forget to export its installation paths in your `PATH` and `LD_LIBRARY_PATH` env vars. Put something like this in your `~/.bashrc` file for example, changing the version accordingly to whichever one you have installed:
 
 ```bash
-sudo apt install build-essential cmake tmux clang-tidy autoconf libtool pkg-config libabsl-dev libboost-all-dev libc-ares-dev libcrypto++-dev libgrpc-dev libgrpc++-dev librocksdb-dev libscrypt-dev libsnappy-dev libssl-dev zlib1g-dev openssl protobuf-compiler protobuf-compiler-grpc unison git

 **Please note that installing dependencies through the script only works on APT-based distros** (Debian, Ubuntu and derivatives) - you can still check the dependencies on any distro, but installing them requires APT. For distros with other package managers and/or distros older than the minimum ones listed above, you're on your own.

+### GCC-specific tips
+
+For Debian specifically, you can (and should) use `update-alternatives` to register and set your GCC version to a more up-to-date build if required.
+
+If you're using a self-compiled GCC build out of the system path (e.g. `--prefix=/usr/local/gcc-X.Y.Z` instead of `--prefix=/usr/local`), don't forget to export its installation paths in your `PATH` and `LD_LIBRARY_PATH` env vars (to prevent e.g. "version `GLIBCXX_...'/`CXXABI_...` not found" errors). Put something like this in your `~/.bashrc` file for example, changing the version accordingly to whichever one you have installed:
 
 ```bash

 There is a script called `scripts/deps.sh` which you can use to check if you have those dependencies installed (`deps.sh --check`), and install them in case you don't (`deps.sh --install`). The script expects dependencies to be installed either on `/usr` or `/usr/local`, giving preference to the latter if it finds anything there (so you can use a higher version of a dependency while still keeping your distro's default one).
 
-**Please note that installing dependencies through the script only works on APT-based distros** (Debian, Ubuntu and derivatives) - you can still check the dependencies on any distro, but installing them requires APT. For distros with other package managers and/or distros older than the minimum ones listed above, you're on your own.
+**Please note that installing most dependencies through the script only works on APT-based distros** (Debian, Ubuntu and derivatives) - you can still check the dependencies on any distro and install the few ones labeled as "external" (those are fetched through `git`), but if you're on a distro with another package manager and/or a distro older than one of the minimum ones listed above, you're on your own.

+### Tips for dependencies
+
 There is a script called `scripts/deps.sh` which you can use to check if you have those dependencies installed (`deps.sh --check`), and install them in case you don't (`deps.sh --install`). The script expects dependencies to be installed either on `/usr` or `/usr/local`, giving preference to the latter if it finds anything there (so you can use a higher version of a dependency while still keeping your distro's default one).
 
 **Please note that installing most dependencies through the script only works on APT-based distros** (Debian, Ubuntu and derivatives) - you can still check the dependencies on any distro and install the few ones labeled as "external" (those are fetched through `git`), but if you're on a distro with another package manager and/or a distro older than one of the minimum ones listed above, you're on your own.
 
-### GCC-specific tips
-
 For Debian specifically, you can (and should) use `update-alternatives` to register and set your GCC version to a more up-to-date build if required.
 
 If you're using a self-compiled GCC build out of the system path (e.g. `--prefix=/usr/local/gcc-X.Y.Z` instead of `--prefix=/usr/local`), don't forget to export its installation paths in your `PATH` and `LD_LIBRARY_PATH` env vars (to prevent e.g. "version `GLIBCXX_...'/`CXXABI_...` not found" errors). Put something like this in your `~/.bashrc` file for example, changing the version accordingly to whichever one you have installed:

 ### Tips for dependencies
 
-There is a script called `scripts/deps.sh` which you can use to check if you have those dependencies installed (`deps.sh --check`), and install them in case you don't (`deps.sh --install`). The script expects dependencies to be installed either on `/usr` or `/usr/local`, giving preference to the latter if it finds anything there (so you can use a higher version of a dependency while still keeping your distro's default one).
+There is a script called `scripts/deps.sh` which you can use to check if you have those dependencies installed (`deps.sh --check`), install them in case you don't (`deps.sh --install`), and clean up the external ones for reinstalling (`deps.sh --cleanext`). The script expects dependencies to be installed either on `/usr` or `/usr/local`, giving preference to the latter if it finds anything there (so you can use a higher version of a dependency while still keeping your distro's default one).
 
 **Please note that installing most dependencies through the script only works on APT-based distros** (Debian, Ubuntu and derivatives) - you can still check the dependencies on any distro and install the few ones labeled as "external" (those are fetched through `git`), but if you're on a distro with another package manager and/or a distro older than one of the minimum ones listed above, you're on your own.
