new update of the pr with network limits
more debug options:
discarding downloaded blocks all or after given height.
trying to trigger the locking errors.
debug levels polished/tuned to sane values.
debug/logging improved.
warning: this pr should be correct code, but it could make
an existing (in master version) locking error appear more often.
it's a race on the list (map) of peers, e.g. between closing/deleting
them versus working on them in net-limit sleep in sending chunk.
the bug is not in this code/this pr, but in the master version.
the locking problem of master will be fixed in other pr.
problem is ub, and in practice is seems to usually cause program abort
(tested on debian stable with updated gcc). see --help for option
to add sleep to trigger the error faster.
Update of the PR with network limits
works very well for all speeds
(but remember that low download speed can stop upload
because we then slow down downloading of blockchain
requests too)
more debug options
fixed pedantic warnings in our code
should work again on Mac OS X and FreeBSD
fixed warning about size_t
tested on Debian, Ubuntu, Windows(testing now)
TCP options and ToS (QoS) flag
FIXED peer number limit
FIXED some spikes in ingress/download
FIXED problems when other up and down limit
commands and options for network limiting
works very well e.g. for 50 KiB/sec up and down
ToS (QoS) flag
peer number limit
TODO some spikes in ingress/download
TODO problems when other up and down limit
added "otshell utils" - simple logging (with colors, text files channels)
dde7897 Disable legacy fees for now (iamsmooth)
cc74b43 Remove DEFAULT_FEE, add temporary acceptance of too-small per-kb fee >= 0.1, denominations based on DEFAULT_DUST_THRESHOLD, document fee arg to create_transactions as unused, se DEFAULT_DUST_THRESHOLD for wallet dust collection instead of calcualted tx fee (iamsmooth)

If the "enforce DNS checkpoints" flag is not enabled, it should not exit
if DNS checkpoints conflict with the others, but should still print a
warning to the user.
json checkpoints will be checked every 10 minutes, dns every 60.
json checkpoints always enforced, dns still with flag.
conflicting checkpoints is hard fail, but soft if dns enforce flag not
set and dns checkpoints are wonky.
Bounds checking on blockchain_storage' m_blocks.size() when validating
against checkpoints. Also moved initial json & DNS checkpoints load to
after blockchain init.
The daemon should now check for updated checkpoints from
checkpoints.moneropulse.org as well as from the configured json file
every ~1hr (and on launch).
The daemon now has a flag to enable enforcing these checkpoints (rather
than just printing a warning when they fail).
TODO: an easily configurable list of DNS servers to check for
checkpoints as opposed to the hard-coded "checkpoints.moneropulse.org"
For checkpoints being read at runtime to work correctly, the checkpoint
add code needs to not return false if a checkpoint is added that already
exists. In this case, instead return false if the checkpoint is for a
height that already has a checkpoint and the hashes are different.
