2021-02-18Merge #19809: log: Prefix log messages with function name and source code ↵Wladimir J. van der Laan
location if -logsourcelocations is set b4511e2e2ed1a6077ae6826a9ee6b7a311293d08 log: Prefix log messages with function name if -logsourcelocations is set (practicalswift) Pull request description: Prefix log messages with function name if `-logfunctionnames` is set. Yes, exactly like `-logthreadnames` but for function names instead of thread names :) This is a small developer ergonomics improvement: I've found this to be a cheap/simple way to correlate log output and originating function. For me it beats the ordinary cycle of 1.) try to figure out a regexp matching the static part of the dynamic log message, 2.) `git grep -E 'Using .* MiB out of .* requested for signature cache'`, 3.) `mcedit filename.cpp` (`openemacs filename.cpp` works too!) and 4.) search for log message and scroll up to find the function name :) Without any logging parameters: ``` $ src/bitcoind -regtest 2020-08-25T03:29:04Z Using RdRand as an additional entropy source 2020-08-25T03:29:04Z Using 16 MiB out of 32/2 requested for signature cache, able to store 524288 elements 2020-08-25T03:29:04Z Using 16 MiB out of 32/2 requested for script execution cache, able to store 524288 elements 2020-08-25T03:29:04Z Loaded best chain: hashBestChain=0fff88f13cb7b2c71f2a335e3a4fc328bf5beb436012afca590b1a11466e22ff height=0 date=2011-02-02T23:16:42Z progress=1.000000 2020-08-25T03:29:04Z block tree size = 1 2020-08-25T03:29:04Z nBestHeight = 0 2020-08-25T03:29:04Z Imported mempool transactions from disk: 0 succeeded, 0 failed, 0 expired, 0 already there, 0 waiting for initial broadcast 2020-08-25T03:29:04Z 0 addresses found from DNS seeds ``` With `-logthreadnames` and `-logfunctionnames`: ``` $ src/bitcoind -regtest -logthreadnames -logfunctionnames 2020-08-25T03:29:04Z [init] [ReportHardwareRand] Using RdRand as an additional entropy source 2020-08-25T03:29:04Z [init] [InitSignatureCache] Using 16 MiB out of 32/2 requested for signature cache, able to store 524288 elements 2020-08-25T03:29:04Z [init] [InitScriptExecutionCache] Using 16 MiB out of 32/2 requested for script execution cache, able to store 524288 elements 2020-08-25T03:29:04Z [init] [LoadChainTip] Loaded best chain: hashBestChain=0fff88f13cb7b2c71f2a335e3a4fc328bf5beb436012afca590b1a11466e22ff height=0 date=2011-02-02T23:16:42Z progress=1.000000 2020-08-25T03:29:04Z [init] [AppInitMain] block tree size = 1 2020-08-25T03:29:04Z [init] [AppInitMain] nBestHeight = 0 2020-08-25T03:29:04Z [loadblk] [LoadMempool] Imported mempool transactions from disk: 0 succeeded, 0 failed, 0 expired, 0 already there, 0 waiting for initial broadcast 2020-08-25T03:29:04Z [dnsseed] [ThreadDNSAddressSeed] 0 addresses found from DNS seeds ``` ACKs for top commit: laanwj: Code review ACK b4511e2e2ed1a6077ae6826a9ee6b7a311293d08 MarcoFalke: review ACK b4511e2e2ed1a6077ae6826a9ee6b7a311293d08 🌃 Tree-SHA512: d100f5364630c323f31d275259864c597f7725e462d5f4bdedcc7033ea616d7fc0d16ef1b2af557e692f4deea73c6773ccfc681589e7bf6ba970b9ec169040c7

Specific usage of those messages should be in p2p.py. This PR moves test framework specific constants to p2p.py. It also changes the SUBVERSION constant to be a string instead of a bytes object. That means that it needs to be explicitly converted to a bytes object to serialize into a version message. Failing to do so would cause an easy-to-spot bug. This should avoid silent failures like the one solved in #20522.

Using the given address, `getaddressinfo` will look up which `DescriptorScriptPubKeyMan` can be used to produce that address. It will then return the descriptor for that `DescriptorScriptPubKeyMan` in the `parent_desc` field. The descriptor will be in a normalized form where the xpub at the last hardened step is derived so that the descriptor can be imported to other wallets. Tests are added to check that the correct descriptor is being returned for the wallet's addresses and that these descriptors can be imported and used in other wallets. As part of this PR, a `ToNormalizedString` function is added to the descriptor classes. This really only has an effect on `BIP32PubkeyProvider`s that have hardened derivation steps. Tests are added to check that normalized descriptors are returned.

2021-02-17[test] Check user agent string from test framework connectionsJohn Newbery
Add a check that new connections from the test framework to the node have the correct user agent string. This makes bugs easier to detect if the user agent string ever changes.
2021-02-17[test] Add P2P_SERVICES to p2p.pyJohn Newbery
The messages.py module should contain code and helpers for [de]serializing p2p messages. Specific usage of those messages should be in p2p.py. Therefore specify the nServices value in the calling code, not in the messages.py module.
2021-02-17[test] Move MY_RELAY to p2p.pyJohn Newbery
messages.py is for message and primitive data structures. Specifics about the test framework's p2p implementation should be in p2p.py. Also rename to P2P_VERSION_RELAY. Also rename msg_version.nRelay to relay. In Bitcoin Core, this is referred to as fRelay, since it's a bool, so this field has always been misnamed.

The messages.py module should contain code and helpers for [de]serializing p2p messages. Specific usage of those messages should be in p2p.py. Therefore move MY_VERSION to p2p.py. Also rename to P2P_VERSION to distinguish it from other versioning used in Bitcoin/Bitcoin Core. Also always set the nVersion field in CBlockLocator to 0 and ignore the field in deserialized messages. The field is not currently used for anything in Bitcoin Core.

de85af5cce727981383ac0fe81f635451b331f23 test: store subversion (user agent) as string in msg_version (Sebastian Falbesoner) Pull request description: It seems more natural to treat the "subversion" field (=user agent string, see [BIP 14](https://github.com/bitcoin/bips/blob/master/bip-0014.mediawiki#Proposal)) of a node as pure string rather than a bytestring within the test framework. This is also suggested with the naming prefix in `msg_version.strSubVer`: one probably wouldn't expect a field starting with "str" to be a bytestring that needs further decoding to be useful. This PR moves the encoding/decoding parts to the serialization/deserialization routines so that the user doesn't have to bother with that anymore. Note that currently, in the master branch the `msg_version.strSubVer` is never read (only in `msg_version.__repr__`); However, one issue that is solved by this PR came up while testing #19509 (not merged yet): A decoding script for binary message capture files takes use of the functional test framework convert it into JSON format. Bytestrings will be convered to hexstrings, while pure strings will (surprise surprise) end up without modification in the file. So without this patch, we get: ``` $ jq . out.json | grep -m5 strSubVer "strSubVer": "2f5361746f7368693a32312e39392e302f" "strSubVer": "2f5361746f7368693a302e32302e312f" "strSubVer": "2f5361746f7368693a32312e39392e302f" "strSubVer": "2f5361746f7368693a302e32302e312f" "strSubVer": "2f5361746f7368693a32312e39392e302f" ``` After this patch: ``` $ jq . out2.json | grep -m5 strSubVer "strSubVer": "/Satoshi:21.99.0/" "strSubVer": "/Satoshi:0.20.1/" "strSubVer": "/Satoshi:21.99.0/" "strSubVer": "/Satoshi:0.20.1/" "strSubVer": "/Satoshi:21.99.0/" ``` ACKs for top commit: jnewbery: utACK de85af5cce727981383ac0fe81f635451b331f23 Tree-SHA512: ff23642705c858e8387a625537dfec82e6b8a15da6d99b8d12152560e52d243ba17431b602b26f60996d897e00e3f37dcf8dc8a303ffb1d544df29a5937080f9

There are a few moveonyish/refactoring commits to allow for halfway decent unittests. Basic structure is included for specifying and checking the assumeutxo hash values used to validate activated snapshots. Initially I had specified a few height/hash pairs for mainnet in this change, but because of the security-critical nature of those parameters, I figured it was better to leave their inclusion to a future PR that includes only that change - my intent being that reviewers will be more likely to verify those parameters firsthand in a dedicated PR. Aside from that and the snapshot activation logic, there are a few related changes: - ~~allow caching the `nChainTx` value in the CCoinsViewDB; this is set during snapshot activation. Because we don't necessarily have access to the full chain at the time of snapshot load, this value is communicated through the snapshot metadata and must be cached within the chainstate to survive restarts.~~ - break out `CreateUTXOSnapshot()` from dumptxoutset. This is essentially a move-only change to allow the reuse of snapshot creation logic from within unittests. - ...and a few other misc. changes that are solely related to unittests. The move-onlyish commit is most easily reviewed with `--color-moved=zebra`.

After improving robustness with this approach (commits 1-3), it turned out that there were still some fails, but those were unrelated to zmq: Out of 500 runs, 3 times `sync_mempool()` or `sync_blocks()` timed out, which can happen because the trickle relay time has no upper bound -- hence in rare cases, it takes longer than 60s. This is fixed by enabling immediate tx relay on node1 (commit 4), which as a nice side-effect also gives us a rough 2x speedup for the test. For further details, also see the explanations in the commit messages. There is no guarantee that the test is still not flaky, but it would help if potential reviewers would run the following script locally and report how many runs failed (feel free to do less than 1000 runs, as this takes quite a long if ran with `--valgrind`): ``` #!/bin/sh OUTPUT_FILE=./zmq_results echo ===== repeated zmq test ===== > $OUTPUT_FILE for i in `seq 1000`; do echo ------------------------ echo ----- test run $i ----- echo ------------------------ echo --- $i --- >> $OUTPUT_FILE ./test/functional/interface_zmq.py --valgrind if [ $? -ne 0 ]; then echo "FAILED. /o\\" >> $OUTPUT_FILE else echo "PASSED. \\o/" >> $OUTPUT_FILE fi done echo Failed test runs: grep FAILED $OUTPUT_FILE | wc -l ``` ACKs for top commit: jonatack: Light ACK ef21fb7313005a8a2d4f03fb4056f1f66c1b04f0 with the caveat that I was unable to make the test fail with valgrind both here and on master, so I can't vouch that it actually fixes the CI flakiness.

Effectively, this reverts f4beb4996d27f2cdaf4f0a63e7dc044bf17decce. The difference to the previous version is that this runs with the `--min-confidence 100` setting. From https://pypi.org/project/vulture/: > Use `--min-confidence 100` to only report code that is guaranteed to be unused within the analyzed files. So this should avoid the previous issues where static analysis had wrong positives due to the dynamic nature of Python code by only reporting things that are unambiguous (such as code after a `return` statement). As such, there is not suppressions list. My motivation was mainly #21081 which would have been caught by this (as can be seen by the CI run failing). This is still marked as draft because #21081 is needed to get the linter to pass. Also, there is a second problem that this found (see https://github.com/bitcoin/bitcoin/pull/19509/files#r571454691).

Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible. Two other points: [Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179): > It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet. Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on: * The version of Boost. * The platform you're building for. * Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences). * Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`. A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point. With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc. Previous similar PRs were #19183 & #20922. The authors are included in the commits here. Also related to #21022 - pthread sanity checking.

2021-02-09zmq test: speedup test by whitelisting peers (immediate tx relay)Sebastian Falbesoner
Speeds up the zmq test roughly by a factor of 2x (~20 sec. instead of ~40 sec.) and also avoids timeouts on the synchronization methods (sync_mempool() / sync_blocks()) that happened with a slight chance. This is due to the fact that there is no upper bound on the trickle relay time, so even the default of 60s is sometimes too low. Fixed by enabling immediate tx relay on node1.
2021-02-09zmq test: fix flakiness by using more robust sync methodSebastian Falbesoner
After connecting the subscriber sockets to the node, there is no guarantee that the node's zmq publisher interfaces are ready yet, which means that potentially the first expected notification messages could get lost and the test fails. Currently this is handled by just waiting for a short period of time (200ms), which works most of the time but is still problematic, as in some rare cases the setup time takes much longer, even in the range of multiple seconds. The solution in this commit approaches the problem by using a more robust method of syncing up, originally proposed by instagibbs: 1. Generate a block on the node 2. Try to receive a notification on all subscribers 3. If all subscribers get a message within the timeout (1 second), we are done, otherwise repeat starting from step 1
2021-02-09zmq test: accept arbitrary sequence start number in ZMQSubscriberSebastian Falbesoner
The ZMQSubscriber reception methods currently assert that the first received publisher message has a sequence number of zero. In order to fix the current test flakiness via "syncing up" to nodes in the setup phase, we have to cope with the situation that messages get lost and the first actual received message has a sequence number larger than zero.

Tests which rely on or test legacy wallet behavior are disabled and skipped when BDB is not compiled. For the components of some tests that are for legacy wallet things, those parts of the tests are skipped. For the majority of tests, changes are made so that they can be run with either legacy wallets or descriptor wallets without materially effecting the test. Most tests only need the wallet for balance and transactions, so the type of wallet is not an important part of those tests. Additionally, some tests are wallet agnostic and modified to instead use the test framework's MiniWallet.

Most importantly it fixes the TestShell docs which are simply incorrect. The second commit removes the instances of `setup_clean_clain` in functional tests where it is not changing the default. This used to be part of #19168 which also sought to rename`setup_clean_chain`.

It answers a question anyone new to Bitcoin's P2P protocol has had: "Can I see what messages my node is sending and receiving?". ## Functionality When a new debug-only command line argument `capturemessages` is set, any message that the node receives or sends is captured. The capture occurs in the MessageHandler thread. When receiving a message, it is captured as soon as the MessageHandler thread takes the message off of the vProcessMsg queue. When sending, the message is captured just before the message is pushed onto the vSendMsg queue. The message capture is as minimal as possible to reduce the performance impact on the node. Messages are captured to a new `message_capture` folder in the datadir. Each node has their own subfolder named with their IP address and port. Inside, received and sent messages are captured into two binary files, msgs_recv.dat and msgs_sent.dat, like so: ``` message_capture/203.0.113.7:56072/msgs_recv.dat message_capture/203.0.113.7:56072/msgs_sent.dat ``` Because the messages are raw binary dumps, included in this PR is a Python parsing tool to convert the binary files into human-readable JSON. This script has been placed on its own and out of the way in the new `contrib/message-capture` folder. Its usage is simple and easily discovered by the autogenerated `-h` option. ## Future Maintenance I sympathize greatly with anyone who says "the best code is no code". The future maintenance of this feature will be minimal. The logic to deserialize the payload of the p2p messages exists in our testing framework. As long as our testing framework works, so will this tool. Additionally, I hope that the simplicity of this tool will mean that it gets used frequently, so that problems will be discovered and solved when they are small. ## FAQ "Why not just use Wireshark" Yes, Wireshark has the ability to filter and decode Bitcoin messages. However, the purpose of the message capture added in this PR is to assist with debugging, primarily for new developers looking to improve their knowledge of the Bitcoin Protocol. This drives the design in a different direction than Wireshark, in two different ways. First, this tool must be convenient and simple to use. Using an external tool, like Wireshark, requires setup and interpretation of the results. To a new user who doesn't necessarily know what to expect, this is unnecessary difficulty. This tool, on the other hand, "just works". Turn on the command line flag, run your node, run the script, read the JSON. Second, because this tool is being used for debugging, we want it to be as close to the true behavior of the node as possible. A lot can happen in the SocketHandler thread that would be missed by Wireshark. Additionally, if we are to use Wireshark, we are at the mercy of whoever it maintaining the protocol in Wireshark, both as to it being accurate and recent. As can be seen by the **many** previous attempts to include Bitcoin in Wireshark (google "bitcoin dissector") this is easier said than done. Lastly, I truly believe that this tool will be used significantly more by being included in the codebase. It's just that much more discoverable.
