2020-09-22Add 'sequence' zmq publisher to track all block (dis)connects, mempool deltasGregory Sanders
Using the zmq notifications to avoid excessive mempool polling can be difficult given the current notifications available. It announces all transactions being added to mempool or included in blocks, but announces no evictions and gives no indication if the transaction is in the mempool or a block. Block notifications for zmq are also substandard, in that it only announces block tips, while all block transactions are still announced. This commit adds a unified stream which can be used to closely track mempool: 1) getrawmempool to fill out mempool knowledge 2) if txhash is announced, add or remove from set based on add/remove flag 3) if blockhash is announced, get block txn list, remove from those transactions local view of mempool 4) if we drop a sequence number, go to (1) The mempool sequence number starts at the value 1, and increments each time a transaction enters the mempool, or is evicted from the mempool for any reason, including block inclusion. The mempool sequence number is published via ZMQ for any transaction-related notification. These features allow for ZMQ/RPC consumer to track mempool state in a more exacting way, without unnecesarily polling getrawmempool. See interface_zmq.py::test_mempool_sync for example usage.
2020-09-15scripted-diff: Rename SendMessage to SendZmqMessage.Daniel Kraft
Windows headers define SendMessage as a macro, which leads to problems with the method name "SendMessage". To circumvent this, we rename the method to "SendZmqMessage". -BEGIN VERIFY SCRIPT- sed -i 's/SendMessage/SendZmqMessage/g' src/zmq/zmqpublishnotifier.* -END VERIFY SCRIPT-
2020-09-07Replace zmqconfig.h by a simple zmqutil.Daniel Kraft
zmqconfig.h is currently not really needed anywhere, except that it declares zmqError (which is then defined in zmqnotificationinterface.cpp). Note in particular that there is no need to conditionally include zmq.h only if ZMQ is enabled, because the place in the core code where the ZMQ library itself is included (init.cpp) is conditional already on that. This commit removes zmqconfig.h and replaces it by a much simpler zmqutil.h library for zmqError. The definition of the function is moved to the matching (newly created) zmqutil.cpp.
2020-09-07Various cleanups in zmqnotificationinterface.Daniel Kraft
This is a pure refactoring of zmqnotificationinterface to make the code easier to read and maintain. It replaces explicit iterators with C++11 for-each loops where appropriate and uses std::unique_ptr to make memory ownership more explicit.
2020-09-02Merge #14687: zmq: enable tcp keepaliveJonas Schnelli
c276df775914e4e42993c76e172ef159e3b830d4 zmq: enable tcp keepalive (mruddy) Pull request description: This addresses https://github.com/bitcoin/bitcoin/issues/12754. These changes enable node operators to address the silent dropping (by network middle boxes) of long-lived low-activity ZMQ TCP connections via further operating system level TCP keepalive configuration. For example, ZMQ sockets that publish block hashes can be affected in this way due to the length of time it sometimes takes between finding blocks (e.g.- sometimes more than an hour). Prior to this patch, operating system level TCP keepalive configurations would not take effect since the SO_KEEPALIVE option was not enabled on the underlying socket. There are additional ZMQ socket options related to TCP keepalive that can be set. However, I decided not to implement those options in this changeset because doing so would require adding additional bitcoin node configuration options, and would not yield a better outcome. I preferred a small, easily reviewable patch that doesn't add a bunch of new config options, with the tradeoff that the fine tuning would have to be done via well-documented operating system specific configurations. I tested this patch by running a node with: `./src/qt/bitcoin-qt -regtest -txindex -datadir=/tmp/node -zmqpubhashblock=tcp://127.0.0.1:28332 &` and connecting to it with: `python3 ./contrib/zmq/zmq_sub.py` Without these changes, `ss -panto | grep 28332 | grep ESTAB | grep bitcoin` will report no keepalive timer information. With these changes, the output from the prior command will show keepalive timer information consistent with the configuration at the time of connection establishment, e.g.-: `timer:(keepalive,119min,0)`. I also tested with a non-TCP transport and did not witness any adverse effects: `./src/qt/bitcoin-qt -regtest -txindex -datadir=/tmp/node -zmqpubhashblock=ipc:///tmp/bitcoin.block &` ACKs for top commit: adamjonas: Just to summarize for those looking to review - as of c276df775914e4e42993c76e172ef159e3b830d4 there are 3 tACKs (n-thumann, Haaroon, and dlogemann), 1 "looks good to me" (laanwj) with no NACKs or any show-stopping concerns raised. jonasschnelli: utACK c276df775914e4e42993c76e172ef159e3b830d4 Tree-SHA512: b884c2c9814e97e666546a7188c48f9de9541499a11a934bd48dd16169a900c900fa519feb3b1cb7e9915fc7539aac2829c7806b5937b4e1409b4805f3ef6cd1

3e730bf90aaf53c41ff3a778f6aac15d163d1c0c zmq: Fix due to invalid argument and multiple notifiers (João Barbosa) Pull request description: ZMQ initialization is interrupted if any notifier fails, and in that case all notifiers are destroyed. The notifier shutdown assumes that the initialization had occurred. This is not valid when there are multiple notifiers and any except the last fails to initialize. Can be tested by running test/functional/interface_zmq.py from this branch with bitcoind from master. Closes #17185.

2017-04-01Change LogAcceptCategory to use uint32_t rather than sets of strings.Gregory Maxwell
This changes the logging categories to boolean flags instead of strings. This simplifies the acceptance testing by avoiding accessing a scoped static thread local pointer to a thread local set of strings. It eliminates the only use of boost::thread_specific_ptr outside of lockorder debugging. This change allows log entries to be directed to multiple categories and makes it easy to change the logging flags at runtime (e.g. via an RPC, though that isn't done by this commit.) It also eliminates the fDebug global. Configuration of unknown logging categories now produces a warning.
