Remove misc_language.h: Half of it is unused, half of it is crap doesn't
need to be used, and the two useful things (median calculator and a
scope exit caller) were poorly written.
Rewrote median from scratch and moved it out of epee.
Simplified the scope exit handler and moved it to its own small header
in epee.
openssl is a miserable dependency to fight with, especially for
iOS/Android, and we use it for very little:
- it gets (mis)used to write base64 data to a file in wallet2 for things
like multisig data. However this mode is *not* enabled by default,
basically completely unknown, completely unused, only exists in the
cli wallet, and is just dumb. (Honestly the justification given in
the PR is that "Windows users might want it", presupposing that there
exists Windows users who are capable of generating a multisig wallet
in a CLI-only application and yet are incapable of dealing with binary
files).
- it's a dependency of unbound (in order to do dnssec, I believe).
Unbound itself is fairly useless for Oxen, so I've removed it too:
- it does OpenAlias lookups, which are a Monero thing that has never
been used outside Monero, doesn't work reliably (because it fails
if the result isn't DNSSEC validated) and is pointless when we
have ONS.
- it does DNS resolution on seed nodes, but we have never set seed
nodes by name and just use seed node IPs instead (which seems a
bit better anyway since the DNS lookup leaks some metadata).
- it *was* being used for sha256, but an earlier commit in this PR
already replaced that with libsodium (entirely coincidentally).
- for static deps, it enables HTTPS support for the wallet. However
only the CLI wallet actually supports this (the GUI and mobile wallets
don't), and since oxend hasn't support this for a while I have strong
doubts it is being used anywhere. (Plus wallet3 will do everything
encrypted using zmq/libsodium, so doesn't need this to be secure).
Note here that it is *only* removed by this commit for static builds:
if doing a system build that links to libcurl supporting HTTPS then
HTTPS support will still work.
Libexpat is also gone because it was only there for libunbound.
- Aside from converting code, this commit also:
- Cleans out a bunch of epee garbage that this code touches.
- Removes some of the wipeable_string usage from wallet2 added by
upstream Monero, because that usage was worse than useless: every
instance removed uses a wipeable_string but then *copies the value
into a std::string*, which makes the entire thing useless.
It is, however, *worse* than useless because it is deceptive: a casual
observer would think that the values are being wiped, when in
actuality it only added an extra intermediate buffer that gets wiped
while the final destination doesn't. This deception is worse than
nothing, and so I've removed it.
- Removes epee md5 code. It is entirely unused, and was depending on
the removed hex code.
- Removes a bunch of useless functions from
epee/storages/parserse_base_utils.h: in particular the
exception-to-bool wrappers were only being used in the test suite
(which was dumb: the test suite is perfectly capable of a "does not
throw" assertion).
- De-templatizes the parsing code in parserse_base_utils.h that was only
ever called with a `const char*` "It" (except for one place in the
test suite was which easily fixed), and moved the implementation into
a .cpp file.
We have disabled uPnP by default for nearly a year now (#1423) with no
adverse affects; this commit finishes it off entirely, removing it from
the codebase.
Fixes#1419 -- see discussion in that issue for why UPnP really doesn't
add much utility to Oxen.
All the encoding parts move to oxen-encoding recently; this updates to
the latest version of oxen-mq, adds oxen-encoding, and converts
everything to use oxenc headers rather than the oxenmq compatibility
shims.
This makes reachability testing activate at HF19. We probably want to
come back and update this before HF19, but for now we just check but
don't enforce lokinet reachability.
This option is incredibly misguided: exceptions are a normal part of C++
error handling that are used *as intended* in lots of places in the
code. Spewing massive amounts of output every time any exception is
thrown anywhere (even when caught!) is terrible.
More than that, we don't ever build with it enabled (for the above
reasons) so this is all just unused code.
The ONS burn price was lowered in HF 18 and the testnet has
transactions that are over the adjusted price. The codebase allows
for transactions already on testnet but in process broke the test suite.
See PR #1441 for further details
The important part here is removing this line:
if (swarm_to_snodes.size() == 1) return MAX_ID / 2;
because, if we end up in a case where we have only one swarm and it
*already* has that ID (e.g. create 2, which will be [MAX/2,0] then drop
0) then this returns a swarm_id that already exists, which is bad
because then we fail to insert the new swarm, a service node gets left
with an unassigned swarm id, and that then causes issues in SS because
that node thinks it is deactivated because it doesn't have a swarm id
(yet it *is* in the active nodes list, so other network members still
try to talk to it).
Governance reward calculations were hard-coded for == HF17 rather than
>= 17, so for HF18 it was falling back to the old "add up all the
values" method that we used to use. Updated it to support HF18, and add
a static_assert that will fail to compile (without a fix) when we add
HF19.
Also some minor cleanups (mostly indent changes for unnecessary blocks
-- ignore whitespace when looking at the diff).
7293311c52 broke these tests -- they were
broken already because they were testing values under HF13 rules, so the
15k requirement wasn't kicking in. Updated them to better HF versions,
and fixed the tests to respect the HF16 requirement drop.
For some reason we aren't keeping the old chain as an alt chain anymore,
but that shouldn't be a problem: fix the test as well as make some
improvements in the tests it does.
What we are passing here is invalid, and so raises an exception, but the
test structure here doesn't have a nice way to catch that, so just
disable the test.
This adds a variable hack into loki-core that lets us disable the
transaction hard fork requirement so that the test suite can still
generate transactions under older tx rules even though the transactions
will be modern CLSAG txes.
These are sort of bastardized txes that can never occur on the proper
mainnet, but let us keep tests that apply to v2/v3 transactions even
though we can't actually generate proper v2/v3 transactions anymore.
A few tests got removed here because they are testing for old invalid
bulletproof formats that don't matter anymore because they will never be
accepted on the current chain anyway.
There's no reason we need intermediate blocks, so make it just generate
v7@0 (for genesis), v14s to make funds, and the the target. (Or just
v7@0 + target for <v14 hard fork versions).
- updates tests to work properly with current HF
- makes loki_generate_sequential_hard_fork_table jump 7->14....->15->16
rather than intermediate 8-9-10-11-12-13 blocks. (The 14 sequence is
the generate block rewards before 15 lowers and 16 eliminates mining
rewards).
- remove test relying on the old 30-day expiry; that only worked on old
HFs, but also required old (pre-v4) txes which don't work anymore, so I
just removed the test.
When we need to fill a block we are currently generating a ton of
transactions, but that is fairly slow: much faster to generate a small
number of huge txes.
