Add monero_add_minimal_executable and use in tests
This is done in order not to have to relink targets, when just an .so changed, but not its interface.
Tests running after being compiled with `make debug-test` failed with
```
[ FAILED ] block_reward_and_current_block_weight.fails_on_huge_median_size
[ FAILED ] block_reward_and_current_block_weight.fails_on_huge_block_weight
```
With the introduction of the patch in
be82c40703 (diff-1a57d4e6013984c420da98d1adde0eafL113)
the assertions checking the weight of the median and current block
against a size limit were removed. Since the limit is now enforced by a
long divisor and a uint64_t type, checking in a separate test makes
little sense, so they are removed here.
When given a wrong argument, some daemon commands failed with "unknown
command" error, instead of a meaningful error message. This patch
brings consistency into the error messages.
In several places, this patch removes relatively useful messages,
and replaces them with more generic ones. E.g.,
- std::cout << "use: print_pl [white] [gray] [<limit>] [pruned]
[publicrpc]" << std::endl;
+ std::cout << "Invalid syntax: Too many parameters. For more
details, use the help command." << std::endl;
There are two reasons for this:
1. Consistency.
2. Removing duplicates.
The detailed information about the parameters is present in
the help messages already. Having it in two places increases
the risk that the messages would get out of date.
A 20% fluff probability increases the precision of a spy connected to
every node by 10% on average, compared to a network using 0% fluff
probability. The current value (10% fluff) should increase precision by
~5% compared to baseline.
This decreases the expected stem length from 10 to 5. The embargo
timeout was therefore lowered to 39s; the fifth node in a stem is
expected to have a 90% chance of being the first to timeout, which is
the same probability we currently have with an expected stem length of
10 nodes.
IPv6 addresses include a range that can map IPv4 addresses,
which allowed those mapped addresses to bypass filtering.
This filter should be replaced by AS filtering at some point.
