2019-04-29threads: introduce util/threadnames, refactor thread namingJames O'Beirne
This work is prerequisite to attaching thread names to log lines and deadlock debug utilities. This code allows setting of an "internal" threadname per thread on platforms where thread_local is available. This commit also moves RenameThread() out of a more general module and adds a numeric suffix to disambiguate between threads with the same name. It explicitly names a few main threads using the new util::ThreadRename().

In addition: * They're made safely interruptible (`bitcoind` can be shutdown, and no progress in either will be lost, though if incomplete, `invalidateblock` won't continue after restart and will need to be called again) * The validation queue is prevented from overflowing (meaning `invalidateblock` on a very old block will not drive bitcoind OOM) (see #14289). * `invalidateblock` won't bother to move transactions back into the mempool after 10 blocks (optimization). This is not an optimal solution, as we're relying on the scheduler call sites to make sure the scheduler doesn't overflow. Ideally, the scheduler would guarantee this directly, but that needs a few further changes (moving the signal emissions out of cs_main) to prevent deadlocks. I have manually tested the `invalidateblock` changes (including interrupting, and running with -checkblockindex and -checkmempool), but haven't tried the rewinding (which is probably becoming increasingly unnecessary, as very few pre-0.13.1 nodes remain that would care to upgrade).

to hide tx time d45b344ffd Bucket for inbound when scheduling invs to hide tx time (Gleb) Pull request description: It has been brought up to my attention that current random delays mechanism (originally intended to obfuscate transaction metadata) allows to easily estimate the time a transaction was received by a node. It may be done by connecting multiple observer nodes to the same node. Each of those nodes will generate its own schedule of delays. Combined metadata regarding those events from different sources allows an observer to estimate transaction time. After this patch a spy won't gain additional information by just creating multiple connections to a target.

4a6c0e3dcf Modernize best block mutex/cv/hash variable naming (Pieter Wuille) 45dd135039 Fix csBestBlock/cvBlockChange waiting in rpc/mining (Pieter Wuille) Pull request description: This is an alternative to #11694. It reintroduces a uint256 variable with the best block hash, protected by csBestBlock, and only updated while holding it. Also rename the involved variable to modern guidelines, as there are very few uses.

2018-04-02Merge #11742: rpc: Add testmempoolacceptWladimir J. van der Laan
b55555d rpc: Add testmempoolaccept (MarcoFalke) Pull request description: To check if a single raw transaction makes it into the current transaction pool, one had to call `sendrawtransaction`. However, on success, this adds the transaction to the mempool with no easy way to undo. The call `testmempoolaccept` is introduced to provide a way to solely check the result without changing the mempool state.
