Ain't nobody got time for link/cmake skullduggery.

2b4cab3 epee: fix potential hang on exit (moneromooo-monero)
|
|
Also close sockets on failure, just in case
|
|
Useful for debugging users' logs
|
|
|
|
and all other associated IPC
|
|
Use boost::unordered_map instead.
|
|
|
|
Instead of using boost::uuids::generate_random, which uses
uninitialized stuff *on purpose*, just to annoy people who
use valgrind
|

Since connections from the ::connect method are now kept in
a deque to be able to cancel them on exit, this leaks both
memory and a file descriptor. Here, we clean those up after
30 seconds, to avoid this. 30 seconds is higher then the
5 second timeout used in the async code, so this should be
safe. However, this is an assumption which would break if
that async code was to start relying on longer timeouts.
|
|
When the boost ioservice is stopped, pending work notifications
will not happen. This includes deadline timers, which would
otherwise time out the now cancelled I/O operations. When this
happens just after starting a new connect operation, this can
leave that operations in a state where it won't receive either
the completion notification nor a timeout, causing a hang.
This is fixed by keeping a list of connections corresponding
to the connect operations, and cancelling them before stopping
the boost ioservice.
Note that the list of these connections can grow unbounded, as
they're never cleaned up. Cleaning them up would involve
working out which connections do not have any pending work,
and it's not quite clear yet how to go about this.

It does not expose the RPC for commands like start_mining, etc
(ie, commands a public node operator might want to be restricted)
|
|
With minor cleanup and fixes (spelling, indent) by moneromooo
|
|
old unbound #warning does not block compilation
unit tests build fine. Even though the RPC/P2P network type is required again
|
|
works for unit tests build, too
|
|
|
|
|
|
|
|
Daemon interactive mode is now working again.
RPC mapped calls in daemon and wallet have both had connection_context
removed as an argument as that argument was not being used anywhere.

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.

thought it was already fixed, apparently commit got lost somewhere
|

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)
