c37851de5752f107c16e19317f28038b6b7ca2dc rpc: Make unloadwallet wait for complete wallet unload (João Barbosa)
Pull request description:
Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.
This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.
Replaces #14919, fixes#14917.

f1bd03eb013b96ff040a8f835e4137fbd2a38cda [depends, zmq, doc] upgrade zeromq to 4.2.5 and avoid deprecated zeromq api functions (mruddy)
Pull request description:
Upgrade the ZeroMQ dependency from version 4.2.3 to the latest stable version 4.2.5.
This PR Follows the lead of https://github.com/bitcoin/bitcoin/pull/11986.
I upgraded both patch files to correspond to the version `4.2.5` libzmq files.
I assume doing so is still necessary and correct.
Without updating the patch line numbers, things appear to work, but you get extra log messages while building `depends` because things don't exactly match, e.g.:
```
/bitcoin/depends> make zeromq
Extracting zeromq...
/bitcoin/depends/sources/zeromq-4.2.5.tar.gz: OK
Preprocessing zeromq...
patching file src/windows.hpp
Hunk #1 succeeded at 58 (offset 3 lines).
patching file src/thread.cpp
Hunk #1 succeeded at 307 with fuzz 2 (offset 87 lines).
Hunk #2 succeeded at 323 with fuzz 2 (offset 90 lines).
```
Updating the patches seemed cleaner, so I did it. Note that libzmq had some whitespace changes, so that's why the updated patches do too.

Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/13213.
Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected.
Two points:
- The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used?
- Should we do something like this to regtest? Or these "niceties" do not matter when on regtest?
Thanks!

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

895e6bbb2241e9175463734f3677398a9f38f0f8 build: if VERSION_BUILD is non-zero, include it in the package version (Andrew Chow)
Pull request description:
As noted on IRC, the filenames of the gitian build results do not contain the 4th digit of the version number if it has one, e.g. 0.17.0.1 produces files with the number 0.17.0. Furthermore, when RC's are built, the resulting filenames are of the release version and do not include `rc` in them. This occurs because `configure.ac` is written to create version numbers of the form `major.minor.rev` instead of `major.minor.rev.build` and without any rc version as it does not handle rc numbers.
This PR changes `configure.ac` to include the build number if it is greater than 0. It will also include the rc number if it is greater than 0. So the filenames of the gitian builds will now contain the full version number.
This behavior can be tested by setting `_CLIENT_VERSION_BUILD` and `_CLIENT_VERSION_RC` to non-zero values and then doing `make dist`. A tar file should be created with the correct versioning.

aa929abf8dc022e900755234c857541faeea8239 [docs] Update developer notes to discourage very long lines (John Newbery)
Pull request description:
Mandatory rules on line lengths are bad - there will always be cases where a longer line is more readable than the alternative.
However, very long lines for no good reason _do_ hurt readability. For example, this declaration in validation.h is 274 chars:
```c++
bool ConnectTip(BlockValidationState& state, const CChainParams& chainparams, CBlockIndex* pindexNew, const std::shared_ptr<const CBlock>& pblock, ConnectTrace& connectTrace, DisconnectedBlockTransactions& disconnectpool) EXCLUSIVE_LOCKS_REQUIRED(cs_main, m_mempool.cs);
```
That won't fit on one line without wrapping on my 27" monitor with a comfortable font size. Much easier to read is something like:
```c++
bool ConnectTip(BlockValidationState& state, const CChainParams& chainparams,
CBlockIndex* pindexNew, const std::shared_ptr<const CBlock>& pblock,
ConnectTrace& connectTrace, DisconnectedBlockTransactions& disconnectpool)
EXCLUSIVE_LOCKS_REQUIRED(cs_main, m_mempool.cs);
```
Therefore, _discourage_ (don't forbid) line lengths greater than 100 characters in our developer style guide.
100 chars is somewhat arbitrary. The old standard was 80, but that seems very limiting with modern displays.

5c3eaf9983043db1b61a98c95d692a6958670b86 doc: Add warnings for http interfaces limitations (Fabian Jahr)
Pull request description:
`libevent`, which is used for our rest interface, can use up all of the available file descriptors in a system if too many connections are opened at once. If a new block is connected at the same time and can not be written to disk because there are no file descriptors available, the node crashes. Based on my investigation so far the issue is best solved upstream which means we have to wait for the next release (2.2). In the meantime it would be good if we would warn users of this limitation.
See #11368 for more background.

d48c1e837ae1bd08e0f18ad1b57ff72675c3d6ad Add window final block height to getchaintxstats (Jonathan "Duke" Leto)
Pull request description:
This patch is motivated by the desire to make the output of `getchaintxstats` more useful and optimized for applications to consume and render the data.
Firstly, this data is already available to the RPC, no additional work is done. Currently additional RPC calls will be needed to look up the height of the final block in the window or the block height that began the window.
By adding the block height of the final block in the window, the JSON is "self-contained" and applications can calculate the exact block height range of the window with no additional RPC requests.
For example, a web application which wants to render historical information for `getchaintxstats` RPC on various window sizes might call the RPC with various window lengths, once per day, and store the JSON results somewhere. Because the final block height of each dataset is included, it's no extra work to determine the exact block window range of each JSON response.

64b27c46e4c21fc7902a69d8ddb6791ef417c4af docs: add reduce-memory.md (fanquake)
Pull request description:
Following some discussion in https://github.com/bitcoin-core/docs/issues/50, this adds Wladimir's [reducing bitcoind memory usage gist](https://gist.github.com/laanwj/efe29c7661ce9b6620a7) to `/doc`.
The conclusion seemed to be that if the main repo already has [reduce-traffic.md](https://github.com/bitcoin/bitcoin/blob/master/doc/reduce-traffic.md), then we could also add `reduce-memory.md`.

01971da9bd docs: Add productivity notes for "dummy rebases" (Carl Dong)
Pull request description:
When rebasing, we often want to do a "dummy rebase" whereby we are not rebasing over an updated master. This is because rebases can be confusing enough already, and we don't want to resolve upstream conflicts together with our local rebase conflicts due to fixup commits, commit rearrangements, and such. This productivity section details how to do such "dummy rebase"s.

a67d71311d [doc] developer-notes.md: point out that UniValue deviates from upstream (Sjors Provoost)
Pull request description:
While debugging an issue I was somewhat surprised to [learn](https://github.com/bitcoin/bitcoin/pull/14164#issuecomment-419752678) that we've moved `src/univalue` from https://github.com/jgarzik/univalue to https://github.com/bitcoin-core/univalue, that these repos are both maintained and they're different.
The first mention of using the bitcoin-core repo is from late 2015 in #7157. I didn't check when the last common ancestor commit is.
I couldn't find documentation as to why (these things just happen in open source of course), but at minimum we should make this more clear.
There's also the following line in `config.ac` that I'm not sure what to do with:
```
AC_INIT([univalue], [1.0.3],
[http://github.com/jgarzik/univalue/])

Rationale:
For new developers, they might be confused if they see that function arguments are sometimes `camelCase`'d in the codebase. This makes it clear that they _should_ be `snake_case`'d (maybe because no one's gotten to fixing them yet).

-------------------------------
This refactors the tx index code to be in it's own class and get built concurrently with validation code. The main benefit is decoupling and moving the txindex into a separate DB. The primary motivation is to lay the groundwork for other indexers that might be desired (such as the [compact filters](https://github.com/bitcoin/bips/pull/636)). The basic idea is that the TxIndex spins up its own thread, which first syncs the txindex to the current block index, then once in sync the BlockConnected ValidationInterface hook writes new blocks.
### DB changes
At the suggestion of some other developers, the txindex has been split out into a separate database. A data migration runs at startup on any nodes with a legacy txindex. Currently the migration blocks node initialization until complete.
### Open questions
- Should the migration of txindex data from the old DB to the new DB block in init or should it happen in a background thread? The downside to backgrounding it is that `getrawtransaction` would return an error message saying the txindex is syncing while the migration is running.
### Impact
In a sample size n=1 test where I synced nodes from scratch, the average time [Index writing](https://github.com/bitcoin/bitcoin/blob/master/src/validation.cpp#L1903) was 3.36ms in master and 1.72ms in this branch. The average time between `UpdateTip` log lines for sequential blocks between 400,000 and IBD end on mainnet was 0.297204s in master and 0.286134s in this branch. Most likely this is just variance in IBD times, but I can try with some more trials if people want.
