util.c:
- fix in empty section at the end of the state, showed as bug when having an empty name
DHT.c:
- fix in saving less data than originally announced, showed as bug when not having reached any clients ever (no clients or only with timestamp of zero)
auto_test/crypto_test.c:
- test "endtoend": increased timeout from default ~5s to 15s, making it pass on slower systems
- signed/unsiged warning fixed by cast
- addr_resolve(): for() instead of while(), flip conditions for a much neater function (suggested by Andreas Schneider)
- ip_ntoa(): enforced termination: terminate at the maximum position, that's the one snprintf() may forget
- networking_poll(): forgot tabs2spaces
- get_close_nodes()/sendnodes()/sendnodes_ipv6(): when selecting for SEND_NODES/SEND_NODES_IPV6, treat embedded IPv4-in-IPv6 addresses as being IPv4
Messenger.c:
- added a named constant for sixty seconds friend/client dump
- fix logging to convert client_id to printable before printing
Primary rationale: The part that DHT saves changes if IP is expanded to IPv6. To let people keep their friends/name, change the datafile format now, while everybody is still on the same page.
Loading/Saving rewritten to allow a part of the file to be incomprehensible to the loading routine.
Added a magic cookie at the beginning to mark the file as tox's.
Changes in some part of the datafile can be skipped and the remaining parts still be consumed.
Allows a wide margin of forward compatibility (like the IP to IPv6 transition, but also e.g. a change in the key format).
As long as the file is not completely garbled, the routine will read as much as possible. Only the KEY section is considered mandatory: a malformed key section leads to a negative result.
util.*:
- holds the driving function which jumps from section to section and calls back with section length and tag (type)
Messenger.c,DHT.*:
- new loading functions call the util-function with a callback, which subsequently consumes the sections
- old routines are kept to fall back onto if the magic cookie at the beginning isn't present
- saving is still done in one local routine
