I did this by copying the updated bech32 code, and then re-patching in
our minor changes:
1. Headers modded (we need size_t)
2. Explicit length for bech32_encode/decode (not 90).
3. Exposing and bech32_ prefix for convert_bits, charset, charset_rev.

We should actually be including this (as it may define _GNU_SOURCE
etc) before any system headers. But where we include <assert.h> we
often didn't, because check-includes would complain that the headers
included it too.
Weaken that check, and include config.h in C files before assert.h.

Sometimes it's v0.9.3 and sometimes it's 0.9.3, and I always get it
wrong. This is painful when you have to create a signed tag after
committing to one of the two only to find out you chose wrong and have
to redo the tagging.
This would cause a segfault on the default network parameter for
`dumponchaindescriptors`.

tools: Add `generatehsm` method to hsmtool to derivate BIP32 seeds from a
mnemonic using the BIP39 standard.
The new method uses libwally for the BIP39 to BIP32 derivation. It also
fails if an hsm_secret file already exists, so we do not overwrite
someone else's wallet without noticing.
It allows the use of passphrases, the ECHO mode in the terminal is
disable for higher security.
It currently supports "en", "es", "fr", "it", "jp", "zhs", "zht".

Changelog-Fixed: Actually make the password argument optional for `guesstoremote` and `dumpcommitments` sub-commands, as shown in our documentation and help text.
Reported by `Barno` on #c-lightning IRC.
Before this, docker image will never detects that
`lightning-rpc` was created if it is running in regtest
or testnet, because the file will be created under
subfolder for each network name, and entrypoint does not
check "lightning-rpc" file in those folders.
By specifying `LIGHTNINGD_NETWORK` environment var
in dockerfile, we can now check correct path.
Changelog-Added: Docker build now includes `LIGHTNINGD_NETWORK` ENV variable which defaults to "bitcoin". An user can override this (e.g. by `-e` option in `docker run`) to run docker container in regtest or testnet or any valid argument to `--network`.
Changelog-Added: We now install `lightning-hsmtool` for your `hsm_secret` needs.
See: https://github.com/ElementsProject/lightning/issues/3717#issuecomment-644844594
It seems reasonable to add this to the standard install, and to document it properly as well, hopefully we can fill in the documentation better later on.
According to #3226, it looks like clang's LD error format has changed.
This patch adds the new format so we can parse the mocks successfully.

`struct tx_parts` is just a txid and a bunch of inputs and outputs,
some of which may be NULL.
This is both a nod towards a future where we (or our peer) can combine
HTLCs or (in an eltoo world) commitments, although for the moment all
our tx_parts will be complete.
It also matches our plan to split `bitcoin_tx` into two types: this
`struct tx_parts` where we don't know input amounts etc, and `psbt`
where we do.

- we've moved tmpctx management to setup.c from daemon.c, so we update
the `check-tmpctx`
- `common_setup(char *)` is now a valid analog for `setup_locale`, so we

char *fmt_wireaddr_without_port(const tal_t *ctx UNNEEDED, const struct wireaddr *a UNNEEDED)

When we have only a single member in a TLV (e.g. an optional u64),

Before this patch we used to send `double`s over the wire by just
copying them. This is not portable because the internal represenation
of a `double` is implementation specific.
Instead of this, multiply any floating-point numbers that come from
the outside (e.g. JSONs) by 1 million and round them to integers when
handling them.
* Introduce a new param_millionths() that expects a floating-point
number and returns it multipled by 1000000 as an integer.
* Replace param_double() and param_percent() with param_millionths()
* Previously the riskfactor would be allowed to be negative, which must
have been unintentional. This patch changes that to require a
non-negative number.
Changelog-None
Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.
To resolve this:
* Introduce an error code type with a known size:
`typedef s32 errcode_t`.
* Change all error code macros to constants of type `errcode_t`.
Constants also play better with gdb - it would visualize the name of
the constant instead of the numeric value.
* Change all functions that take error codes to take the new type
`errcode_t` instead of `int`.
* Introduce towire / fromwire functions to send / receive the newly added
type `errcode_t` and use it instead of `towire_int()`.
In addition:
* Remove the now unneeded `towire_int()`.
* Replace a hardcoded error code `-2` with a new constant
`INVOICE_EXPIRED_DURING_WAIT` (903).
Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2
We cannot let users use `sendcustommsg` to inject messages that are handled
internally since it could result in our internal state tracking being borked.
I really want a type which means "I am a wrapped onion reply" as separate
from "I am a normal wire msg". Currently both user u8 *, and I got very
confused trying to figure out where each one was an unwrapped error msg,
or where it still needed (un)wrapping.

Add towire_int() and fromwire_int() functions to "(de)serialize"
"int". This will only work as long as both the caller of towire_int()

of signed integers and have the same sizeof(int).

TIL: `rename` doesn't like its source and target to be on different
partitions. This was causing the `hsmtool` tests to fail whenever we ran them
on a different partition than the lightning-dir (e.g., `/dev/shm` for faster
testing), because we made the backup copy in the current working directory.
This changes this and creates the backup next to the original file, which has
a reasonable chance to be on the same partition.
Changelog-Changed: hsmtool: The `hsmtool` now creates its backup copy in the same directory as the original `hsm_secret` file.
Recent FreeBSD versions use LLVM's lld as a linker, not the GNU ld.
Their behavior slightly differs, so adapt the build system to handle
either one.
* The LLVM's linker prints "undefined symbol:" instead of
"undefined reference to". Tweak tools/mockup.sh to also look for that
message.
* The LLVM's linker may only print the first dozen errors (omitting
the rest to avoid flooding the screen). tools/update-mocks.sh relies
on getting all errors as it extracts the missing symbols' names from
the error output and creates mocks for them. Detect if errors were
omitted and re-run, telling the linker to not omit any. The GNU linker
does not support -error-limit=0, so unfortunately we can't just run
with that option unconditionally from the first attempt.
* Nit: FreeBSD's sed(1) prints "t" for "\t" instead of a horizontal tab.
Use a verbatim tab in the command, instead of "\t" which works on
both.
Changelog-Fixed: Developer mode compilation on FreeBSD.

This, in the case of data loss on a channel with `option_static_remotekey`

Since the parser itself just parses and doesn't include validation anymore we
need to put that functionality somewhere. The validation consists of enforcing
that the types are in monotonically increasing order without duplicates and
that for the even types we know how to handle it.
We were weaving in and out of generic code through `fromwire_tlvs` with custom
parameters defining the types in that namespace. This hard-wires the parser
with the namespace's types. Slowly trying to deprecate `fromwire_tlvs` in
favor of this typesafe variant.
