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.

a62e667296 docs: Add more Doxygen information to Developer Notes (Jon Layton)
Pull request description:
Update information about Doxygen in `doc/developer-notes.md`.
Alternatively, this could have its own file (like `doc/web-documentation.md`), since there are installation steps included.
For example, I had to run:
```
brew install doxygen graphviz
```
on MacOS, otherwise failures occurred.
This information could also be linked to the `doc/release-process.md`.

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/])
```

b6718e373e tests: Use MakeUnique to construct objects owned by unique_ptrs (practicalswift)
Pull request description:
A subset of #14211 ("Use MakeUnique to construct objects owned by unique_ptrs") as suggested by @MarcoFalke in https://github.com/bitcoin/bitcoin/pull/14211#issuecomment-423324019.
Use `MakeUnique` to construct objects owned by `unique_ptr`s.
Rationale:
* `MakeUnique` ensures exception safety in complex expressions.
* `MakeUnique` gives a more concise statement of the construction.

Pull request description:
When analysing includes in the project it is often assumed that the preferred bracket include syntax (`#include <foo.h>`) mentioned in `developer-docs.md` is used consistently. @sipa:s excellent circular dependencies script [`circular-dependencies.py`](50c69b7801/contrib/devtools/circular-dependencies.py) (#13228) is an example of a script making this reasonable assumption.
This PR enables automatic Travis checking of the include syntax making sure that the bracket syntax includes (`#include <foo.h>`) is used consistently.

Suggested formatting for namespaces in the developer guide is currently
inconsistent. This commit updates the developer guide and clang-format
configuration to consistently put "namespace" and opening/closing braces
on the same line. Example:
```c++
namespace boost {
namespace signals2 {
class connection;
} // namespace signals2
} // namespace boost
```
Currently the "Source code organization" section has an example like the one
above, but the "Coding style" section example and description put a newline
between the opening "namespace foo" and brace (but oddly no newline between
closing namespace and brace).
Avoiding newlines before namespace opening braces makes nested declarations
less verbose and also avoids asymmetry with closing braces. It's also a
common style used in other codebases:
* https://google.github.io/styleguide/cppguide.html#Namespaces
* https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Classes
* https://llvm.org/docs/CodingStandards.html#namespace-indentation

6feb46c Add --with-sanitizers option to configure (Evan Klitzke)
Pull request description:
This adds configure options for `-fsanitize=address`, `-fsanitize=thread`, and `-fsanitize=undefined` which are all disabled by default. These flags are useful for developers who wish to do additional safety checking. Note that some of these are mutually incompatible, and these may have a large performance overhead.
There's some kind of strange logic required to properly check for the availability of these flags in a way that works on both GCC and Clang, hopefully the comments make it clear what's going on.

0bd2ec5 Improve formatting of developer notes (Evan Klitzke)
Pull request description:
The developer notes file has gotten pretty large and unwieldly. This reorganizes some content, most notably by adding a TOC to the page. Compare how the page looks in [my branch](https://github.com/eklitzke/bitcoin/blob/developer-notes/doc/developer-notes.md) vs [master](https://github.com/eklitzke/bitcoin/blob/master/doc/developer-notes.md).
I know there's long-term interest in moving a lot of this content to the bitcoin-core/docs repo on GitHub, but this makes things better now.
The TOC format here is a semi-standard extension to Markdown files that you may have seen on GitHub pages in other projects. The `<!-- markdown-toc -->` comments used by these tools to know where the TOC starts/ends. The following tools all understand this format:
* [Sphinx](http://www.sphinx-doc.org/en/master/)
* [Pandoc](https://pandoc.org/)
* [markdown-toc.el](https://github.com/ardumont/markdown-toc) (what I used)
* various plugins for [vim](https://github.com/mzlogin/vim-markdown-toc) and other editors
I used this TOC extension at a previous job, and my observation is that it's fine if people just edit the TOC manually. It's just text and it's not a huge deal if it gets a little out of sync. It can also be regenerated at any time by anyone with any of these tools.

This change significantly increases IBD performance by increasing the
amount of the UTXO index that can remain in memory. To ensure this
doesn't cause problems in the future, a static_assert on the LevelDB
version has been added, which must be updated by anyone upgrading
LevelDB.

Pull request description:
This is a followup to #10783.
- The first commit doesn't change behavior at all, just simplifies code.
- The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
- The third commit updates developer notes after the cleanup.
- The forth commit does some additional code cleanup in `getbalance`.
Followup changes that should happen in future PRs:
- [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
- [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133

A few "a->an" and "an->a".
"Shows, if the supplied default SOCKS5 proxy" -> "Shows if the supplied default SOCKS5 proxy". Change made on 3 occurrences.
"without fully understanding the ramification of a command" -> "without fully understanding the ramifications of a command".
Removed duplicate words such as "the the".
Add error and range-checking parsers for unsigned 32 and 64 bit numbers.
The 32-bit variant is required for parsing sequence numbers from the
command line in `bitcoin-tx` (see #8164 for discussion). I've thrown in
the 64-bit variant as a bonus, as I'm sure it will be needed at some
point.
Also adds tests, and updates `developer-notes.md`.
I've collected these over time, mostly adding notes after
troubleshooting obscure bugs. As I hope to get the community more
involved in the whole process, I think it is useful to add to the
developer-notes.
